## [1.1.0] — 2026-09-21
The reading side. Nothing here changes how a bundle is built from a folder;
what changes is how a question finds its way into one, and how many bundles
one question can reach.
### Changed
- **A new default ranking: BM25 over passages and titles.** A concept is scored
on its best 500-character passage and on a title/path-weighted field, and the
two are fused by rank. A concept longer than 4 000 characters is delivered as
its answering passage, with `passage: {start, end, of}` saying where in the
concept it sits. The previous fusion stays reachable as `--ranking fusion`.
A reader will see different excerpts, in a different order, for the same
question on the same bundle.
- **BREAKING for anyone who reads the payload: the contract is
`okf-consumption/2`.** `withheld` is no longer a list with one entry per
concept left out; it is a mapping with `total`, `by_rule`, `nearest` (the
best-ranked drops by name, title and source document, 20 by default) and
`complete`. Measured on a large real bundle, the old list was about two
thirds of the written payload and none of it counted against the budget the
payload reported. `--withheld-full` brings the whole list back. The revision
was bumped so that code indexing `withheld` as a list fails loudly instead of
reading the wrong thing. `--withheld-titles` is retired.
- **The server and the generic skill are the standard way in, over a whole
folder.** `okf project` and the front page say it in that order: register
`okf mcp --root` once, on user scope, and every project can ask every bundle
under it; the skill beside a bundle is the supplement for someone who would
rather register nothing. Neither is made again when a bundle is rebuilt.
- **`okf skill` writes ONE generic skill by default**, carrying a working
method and an answer form and no bundle's numbers, so it does not go stale
when a bundle is rebuilt. `--for-bundle` keeps the per-bundle form.
`okf project` puts it at `.claude/skills/okf-consume-any/`.
### Added
- **Several sub-questions in one call.** `okf consume --question A --question
B` (and `questions` on the server's `okf_ask`) reads the bundle once, cuts
each sub-question as if asked alone and interleaves the deliveries under the
same `k` and byte limit. One question gives exactly the payload it gave
before.
- **A map per bundle.** `okf card` and the server's `okf_describe` carry
`map`: one line per source document with its concept titles in document
order, a numbered series folded into one line. The working method is to read
the map first and ask two to four sub-questions in the map's own words.
- **A signal for weak coverage.** The payload's `coverage` carries
`absent_terms` (question words the bundle holds in no form) and `weak` (one
such word, or nothing delivered). It is a reading, not a verdict.
- **A folder of bundles in one command.** `okf card <folder>` shows every
bundle under it, `okf consume <folder>` asks every bundle in one call
(`--bundle-id` narrows it to one), and `okf check` reads that reply, holding
each payload to all 19 rules on its own. These are the same functions the
server runs.
- **A table fragment is read under its heading.** A concept carrying the
proposer's mechanical table title is ranked and shown under the nearest
concept above it in its document; the excerpt keeps `own_title`. No bundle
byte moves.
- **`okf project --gate`**: the gate can be chosen when building a project,
and the bundle's `log.md` names which one ran.
- `okf check` gains `passage_malformed` and `subquestions_unindexed`
(19 rules).
### Removed
- **The old test track tied to one reference corpus is retired.** Its gate
row, its adapters and the tests that read those bundles are gone; public
tests and gates run on invented material. The retrieval gate's premises were
re-measured for BM25.
### Known limitations added
See [Known limitations](README.md#known-limitations): a question worded
differently from the bundle reaches it first through the map's words, the
retrieval gate is red on rows 5, 7 and 8, and speed was not measured.
## [1.0.0] — 2026-09-20
### Added
- **A document the gate refuses WHOLE is named in the run's own summary.**
Measured 2026-09-20 against a real corpus of official documentation built
with the shipped default gate: 17 sources were refused outright, 16 of them
among its ordinary reference pages, and the summary said only
one `fail_secure` line and one `quarantine_review` line. The count of
documents the gate dropped was not there (`rejected (coded)` sums gate
refusals and extraction failures, which have different remedies), the names
were not there, and neither was the way out. `okf build` now prints a
`Documents the gate refused WHOLE` section carrying all four — the count with
its denominator, the names (capped at ten, with the rest in the bundle's
`log.md`), the codes, and `--gate none` for a source you vouch for yourself —
and repeats it in one line on stderr, where a redirected stdout cannot hide
it. `log.md` gains a bullet naming every refused document, uncapped. **The
exit code does not move**: the build is valid, every refusal is coded and the
bundle is a true record of what the gate allowed; what was wrong was the
silence. A run the gate refused nothing from is byte-identical, in the
summary and in `log.md`.
- **A `Known limitations` section on the front page**, high up and before the
install detail: the gate's measured refusals and the way out, the absent
ceiling on what one run pays for images, the three gates of this repository
that are RED and what each red row means for a user, what the content
accounting does not count, and the rough edges nothing is planned for. No new
measurement — every number was already taken.
- **The payload says what of the question it reached** — a new top-level
`coverage` member carrying three lists: the terms the pre-pass read the
question as, the terms no concept in the bundle answers, and the terms no
delivered excerpt answers. Without it a reader holding eight excerpts cannot
tell a bundle that ANSWERED its question from one that merely ranked
something; the two payloads have the same shape. Documented as SS 8 point 7
of `docs/consumption-contract.md`, and the generated consumption skill is
told to read it.
- **Facts, and no verdict, which is a measurement rather than caution.** Two
readings were built and both falsified over **81 questions** (16 synthetic,
65 across three real gold sets, 2026-09-20): the share of a question's
terms a delivered excerpt answers separates the synthetic controls at 0.33
against 0.50 and then REVERSES on real data, where covered questions run
down to 0.27 while one genuinely uncovered question sits at 0.71; and the
share of a bundle tying the best lexical match is ~0.00 for every question
in a large bundle, covered or not. Question style dominates the first and
corpus size the second, so a pre-pass emitting a verdict would assert
across corpora what was measured on one.
- **Contract change, and the cost to a consumer is a re-run.** Every payload
grows the member; the checker does not read it, so a third-party pre-pass
that omits it stays conformant. The SS 7.4 known-positive moves with the
document it is measured on (14 721 / 375 → 16 389 / 417).
- **The retrieval gate is measurable where it was assertable**
(`tools/okf_retrieval_gate.py`, not shipped in the wheel):
- Row 8 prints the identity of every bundle it measured — path,
`bundle_id` and content ref — beside the set's sha256. Measured the same
day: two builds of one consumer's corpus carrying the SAME `bundle_id` at
different refs score differently on the same pinned set, which is why the
ref and not the id is what a row is attributed to.
- `REAL_SET_PINS` states what each of the three real sets IS — questions,
fasit entries, controls and sha256 — so a self-written file in the right
shape is refused instead of reading `1 of 1 | 3 of 3 | GREEN`.
- Row 5 reads the hold-out threshold as a number in [0, 1] and RUNS the
registered set against the registered bundle, printing
`answered of asked = share against threshold`. `bool(threshold)` was the
whole check, so `report-only; any number is acceptable for v1` passed it.
- Row 4's marking reads the payload's `coverage`: `UNANSWERED_BAR = 2/3`,
swept and collapsing at both ends (at 0.50 eleven real covered questions
are marked; at 0.70 the row falls to 5 of 6). The margin is thin — 0.6087
against 0.6667 — and what it does not catch is published with it.
### Changed
- **The two `pip install` lines under "Install in detail" install
`[extract]`.** The first screen installs `llm-ingestion-okf[extract]` and
those two omitted it, so a reader following the detailed instructions got a
build that reports `resolved converter path: unresolved
(extractor_extra_missing)` and reads no binary format. Two recipes, two
different installations.
- **Version `1.0.0`.** The scope this tool is finished at. It adds no
capability over `v0.10.1`; what it adds is that the tool says what it does
not do. After this tag the library is touched for defects found in its own
use, and the next round is Google OKF v0.3.
- **A withheld concept now carries the rule that actually decided it.** The
source quota filters the WHOLE ranked candidate list rather than the top
`k`, so every over-quota candidate came back `source_quota_exceeded` —
including the ones the RANK had already put outside `k`, which the quota
only reached because it ran first. Measured on 25 real misses 2026-09-17:
**13 of them** were labelled by the quota and decided by the rank.
`consume._fates_without_quota` asks the same cut what would have become of
each candidate with no quota in force, and the drop keeps THAT rule; only a
candidate the quota-off cut would have delivered is named as the quota's.
The budget step is lifted into `consume._pack` and used by both, so the
quota-off fate is decided by the code the run itself uses. This moves the
`rule` string a consumer reads for some withheld entries; no delivery, no
rank and no excerpt byte moves, and no committed payload in this repository
changed. The retrieval gate's row 3 goes **2 of 5 RED to 5 of 5 GREEN**.
## [0.10.1] — 2026-09-19
### Removed
- **`tools/okf_adjudicate.py`.** It shelled out to a model CLI at an absolute
path on one machine, which is the one thing nothing in this repository does:
no code here starts another program to judge anything. Its tests go with it.
The two entries below under earlier versions describe what that tool did
while it existed and are left standing — a changelog that edits its own past
is not a record. The K3/K4/K5 reports that used it now say so in the past
tense.
### Added
- **An MCP surface over OKF bundles, in two shapes, plus a generic
consumption skill.** `okf mcp --bundle <dir>` serves exactly one bundle;
`okf mcp --root <dir>` (repeatable) serves every bundle under the roots and
knows none of them by name. Four tools — `okf_list`, `okf_describe`,
`okf_ask`, `okf_fetch` — each with its reason written into the description a
client reads. A single-bundle server exposes **three**: `okf_list` is absent
where there is nothing to list, because a tool that always returns the same
one row invites a client to treat discovery as available when the deployment
does not have it. The eval was written RED first (`tools/okf_mcp_gate.py`,
`5f1772e`); the capability follows.
- **The protocol is written narrowly with stdlib only, and that is the
packaging invariant kept rather than an aesthetic.** An MCP SDK would be
this package's second runtime dependency on the DEFAULT install path, for
four JSON-RPC methods and a newline framing, and
`test_the_only_runtime_dependency_is_the_security_boundary` pins that list
literally. `uv.lock` is untouched.
- **Nothing is cached across calls.** Every call re-walks the roots and
recomputes the bundle's content identity, so a bundle added, removed or
rebuilt while the server runs is seen by the next call without a restart, a
configuration edit or a code change — measured, 9 of 9 discovery checks over
three bundles written while the process was serving. The cost is paid per
call: 0.75 s for the identity of a 2 756-concept bundle, 5.6 s for one ask.
- **Containment is two independent checks**: the bundle's own index must name
the concept, and the resolved path must be inside the bundle. Removing
either one alone still refuses — with a different code, which the gate
asserts by name — and removing both is caught by the gate's row 6.
- **`okf card <bundle>`** prints one bundle's identity, concept count,
conditional-field counts and whole-bundle cost as JSON, DERIVED on every run
and never written into the bundle. **`okf skill --generic`** writes one
installable consumption skill for ANY bundle, carrying no bundle's identity
or numbers and pointing its reader at the card. Measured: two per-bundle
skills are identical on 280 of 312 and 310 lines, and what differs is
exactly what goes stale on a rebuild.
- Report: `docs/2026-09-20-mcp-to-varianter.md`. The gate stands RED on row 2
(83 of 181 anchors of the frozen graded set reached, of which 99 are present
in the bundles at all and 0 were met by a concept-id lookup), and the
architecture choice between the two shapes is the operator's.
- **Every carried image is now one a model can be SHOWN, and the ones that
cannot be are refused out loud.** Until this round the asset path carried
whatever format a publisher shipped. Measured 2026-09-19 over the frozen
R761 delivery's own `assets/` (denominator 50): 29 JPEG, 2 PNG and **19 "PC
bitmap, Windows 3.x, 8-bit, compression 1"** — RLE8 BMP. The 19 are
byte-correct files nothing reads, so 19 of that document's figures were
present and invisible at once, with `images: N` reporting that they had
arrived.
- `assets.VIEWABLE_MEDIA_TYPES` states the set (`image/png`, `image/jpeg`,
`image/gif`, `image/webp`) and `read_image` tests every asset's SNIFFED
type against it. It is a property, not a list of formats we happened to
meet: a format nobody here has seen is refused by the same rule that
refuses TIFF.
- **BMP is converted losslessly to PNG** — 8-bit uncompressed, 8-bit RLE8
and 24-bit uncompressed. The reader is stdlib (`struct` + the existing
`zlib` PNG writer) and adds NO dependency. Pillow was measured first and
rejected on two counts: `read_image` is on the CORE path (`.html` and
`.xml` carry images with no `[extract]` extra), and an asset's name is its
content digest, so encoding through an installed library would make a
bundle's identity move with that library's version — the property 0.10.0
felled page rasterisation over. Pillow is the INDEPENDENT decoder in the
tests instead.
- **Lossless, measured on the real files:** all **19 of 19** R761 RLE8
assets convert with RGB identical to Pillow's decoding of the source,
**2 366 365 pixels** compared.
- **Traceability per converted asset**, on the pointer line where the rest
of the asset metadata already lives: the original media type, the original
sha256 in full, and the new one. A converted asset is ONE asset — one file
in `assets/`, one pointer, one row in the accounting.
- **The ceiling is paid before the pixels exist.** The BMP reader bounds the
DECLARED size through the same `check_size` the rest of the image path
uses, before a row is allocated, and an RLE run is written as one clipped
slice — painting pixel by pixel would leave the memory bounded and the CPU
unbounded, since a megabyte of `FF` runs is a hundred million paint steps
against a 32-pixel frame.
- **Two new codes.** `asset_not_viewable` — a real image in a format no
model can be shown and with no lossless conversion here (TIFF, JPEG 2000).
`asset_bmp_unsupported` — a BMP variant this reader does not express
(RLE4, BITFIELDS, 16/32-bit, BITMAPCOREHEADER, over 256 palette entries).
Both leave a "not carried" line in the concept and a row in the run log.
- **The cost, measured with a committed script** (`tools/okf_asset_census.py`,
one row per image, run from two pinned trees over 18 403 files and 67
PDFs, **9 714 image rows**): exactly **35 rows moved** — 19 BMP now
carried as PNG, and **16 JPEG 2000 objects** that stop being carried and
become `asset_not_viewable`, because no stdlib route decodes JPEG 2000.
**9 321 of 9 321** JPEG and PNG rows are byte-identical on both sides, so
not one already-viewable picture changed hands.
- **One normalisation door in front of the persist gate: U+00AD is removed and
COUNTED** (operator decision 2026-09-18). `llm-ingestion-guard` 1.4.0 keeps
the soft hyphen in `_ZERO_WIDTH_CPS`, and `output:zero-width-present` is an
any-tier carrier — `fail_secure` at every trust level, no sanitisation, no
exception. R761 Prosesskoden:2025 carries 71 of them and 0 of the four real
zero-width characters; all 71 are Norwegian hyphenation points inside words,
so a 701-page process code was unreadable for the whole chain over
typography. `extract.normalise_extracted` removes that one character from
every extracted text; `ExtractedDocument.soft_hyphens`,
`InboxResult.normalised` and the accounting's `normalised_soft_hyphen` carry
the number per document and per run, and `log.md` gains a `**Normalisation**`
bullet. The guard is untouched, the other four characters and U+00A0 NBSP are
untouched, and a real zero-width character is still `fail_secure`. Reach,
measured: **0 of the 78** readable documents of the reference corpus carry
any of the six, so no bundle measured here moves.
- **`refused` in the accounting: a partial refusal is never silent.** The
report and `log.md` now say how many of M documents the run persisted nothing
of. The exit code is unchanged — it belongs to the whole run.
- **`okf build --accounting PATH`: content accounting per element.** Before
extraction, every source document is inventoried in a per-format element
vocabulary: headings, paragraphs, tables, cells, images, and so on. After
the run, every element gets exactly one fate: `carried`, `pointer` or a
coded rejection. The fates are written as JSON to PATH and summarised in
`log.md`. The build then exits 1 when any element is unaccounted or booked
twice.
- **`carried` is checked, not declared.** A persisted document's element is
carried when all of its text is found in the concept bodies written for
that document (letters and digits, case-folded). A document the gate
refused books every element as rejected with the gate's code, and its
`log.md` line says what the source held.
- **The judge is `tools/okf_accounting_gate.py`**, written red first
against an independent witness (`tools/okf_witness.py`, which imports
nothing from this package). At this change it is green on all six rows,
including R761 Prosesskoden:2025: 110 of 110 units under both the default
gate and `--gate none`.
- **Opt-in, measured.** On the 43-document reference corpus the build took
+744 s (+19 %) and +0.53 GB peak RSS.
- **The account is over the element classes the vocabulary knows.** A file
whose suffix has no reader is accounted at file level only, and a part of
a document no vocabulary names is not counted — `.docx` headers, footers,
endnotes and comments, `.pptx` speaker notes, `.xlsx` cell comments and
formulas, the `.rtf` header/footer groups. Content there can go missing
under exit 0 and `0 unaccounted`; README states the list.
- **The reference corpus fails the check, with 24 real losses:** 22 images
on PDF pages without a text layer, which the reader drops together with
the page, and 2 docx Title paragraphs, which the converter moves into
metadata. A default-on door would therefore fail builds that pass today.
Report: `docs/2026-09-17-innholdsregnskapet-bygget.md`.
- **Opt-in by operator decision (2026-09-17)**, until the losses it reports
on the reference corpus are fixed. Of the three exceptions the gate
proposes, the operator approved the PDF one only; approving it moves no
number, because no witness counts a heading in a PDF.
- **Limit, measured:** the check proves that a string is present, not
where. Short elements such as a section label or a one-word title are
often found elsewhere in the same document. With R761's concept text cut
to half, 4 823 paragraphs and 3 621 sections were reported lost, but only
3 titles and 16 labels.
### Changed
- **`okf build` exits 1 when it extracted at least one document and
persisted none.** Until now such a run exited 0, because every refusal was
coded and the conservation identity held. The bundle was nonetheless empty.
Measured case: guard 1.4.0 refuses R761 Prosesskoden:2025 whole, because of
its 71 soft hyphens (U+00AD). Door B's library function
(`process_inbox`) and `corpus.measure` are unchanged; for a hostile inbox,
"all rejected" is a correct outcome.
- In this repository, one test relied on exit 0:
`tests/test_cli_gate.py::test_build_refuses_a_document_the_real_guard_refuses`.
- No script here does. `okf project` calls the build as a function and is
unaffected.
- **A file carried through a document is no longer also a coded rejection.**
Since 0.10.0, an image beside a document was carried into `assets/` through
that document and was ALSO counted as `extractor_unknown`, so one file had
two fates. On R761 under `--gate none` that was 50 files.
- The conservation identity is now `merged + files carried through a
document + coded rejections = N`.
- `log.md` writes the middle term only when it is non-zero, so a corpus with
no such files keeps its line byte for byte.
- The carried files are the references the reader actually resolved and
carried (`ExtractedDocument.files`), never a byte match. A byte match
would credit R761's 7 unpointed duplicates.
- An unpointed file beside a document stays a coded rejection.
- **`log.md`'s `Images: C carried of F found`**: with `--accounting`, F is
what the SOURCES declare. A refused document's pictures therefore no longer
read as "0 of 0 found".
### Security
- **A document can no longer forge a carry in the content-accounting gate
(0.10.1).** New in the viewable-asset round: a converted image's own bytes
are not in `assets/`, so `asset_holds` gained a second route that reads the
two digests the bundle states on the pointer line. The expression ran over
the WHOLE bundle text, so a document could simply write the sentence.
Measured by PM 2026-09-19: a BMP declaring 50 000 x 50 000, refused
`asset_too_large` and absent from `assets/`, was reported as held — through
an image's `alt` text, and through ordinary body text. Before that route
existed, `asset_holds` hashed the source file and nothing a document wrote
could reach it; the gate's own first sentence is that the fasit never comes
from the reader it judges, and `claimed and not found` could be silenced by
a document that asked for it.
- The claim now counts only inside a POINTER BLOCK this code wrote, and only
where it names the asset that block points at. That closes body text and a
table cell.
- An image's LABEL is document text written inside a pointer block, so
`assets._inline` disarms a checksum field in anything that came from the
document: the digits are kept, the colon that makes them a field is not.
That closes the `alt` route. Neither half is sufficient alone.
- Three mutants in `tools/okf_gate_mutants.py`, one per check, each felled by
its own arm; the harness now runs the copy with its own `src/` on
`PYTHONPATH`, because an editable install made a `src/` mutant resolve to
the working tree and survive without having been applied.
- **A remote image reference is no longer a live markdown image link
(0.10.1).** New in 0.10.0: before it, no reader read an `<img>` attribute at
all. A document could put `![fig](https://collect.example.net/p.gif?u=...)`
into a persisted concept, with the address and query string chosen by
whoever wrote the document. This package opens no socket, but a consumer
that renders the bundle — or an agent that fetches what it renders — does,
which turns "this bundle was opened" into a beacon, and a server-side
consumer into an SSRF. The guard refuses such a line at
`guard-user-upload` and the build's default tier does not, so the same bytes
were persisted under the default and refused one tier up. A remote reference
is now inert text with the address in ONE code span, and a property test over
the readers asserts that no reference produces a markdown image link outside
`assets/`. Found by an independent review of 0.10.0 before it was pushed.
- The first fix wrote the address **twice** — once in a code span and once
bare — and a GFM/linkify renderer autolinks a bare URL into `<a href>`.
It takes a click rather than a render, so it is weaker than an image link,
but "inert" was half true. The address is now written once.
- The first fix also **dropped the caption**: `label` stayed in the
signature of the line that says what is missing, and no branch read it, so
the alt text or figure caption of an image the bundle does not carry was
lost — a regression against 0.10.0 and against that line's own reason for
existing. It is written again, in the same `-- <label>` form a carried
pointer uses.
- **An image is bounded in three places, and the third is what the run pays
(0.10.1).** Nothing limited a PDF image's size: a 9.6 KB file declaring
3 000 x 3 000 grayscale zeros took 83 MB of peak RSS and a 63 KB one
declaring 8 000 x 8 000 took 276 MB, linear in the pixel count, so one
document could exhaust memory and take a whole batch build with it — before
any gate, because the guard never sees image bytes.
- The size a container **declares** (`/Width` x `/Height`, an IHDR, a
`data:` payload's encoded length) is checked against `MAX_IMAGE_PIXELS`
(40 000 000) and `MAX_IMAGE_BYTES` (256 MiB) before anything is decoded.
- The size a carried **file** has is checked the same way. This package
never decodes such a file, so it pays nothing for it — but a 7 000 x 7 000
PNG of 47 705 bytes written into a bundle hands the consumer the same bomb
with `7000x7000 px` printed beside it.
- What the **stream** behind a PDF image decompresses to is measured, a
chunk at a time and discarded, before `get_data()` is called. That is an
independent number from the declared size: `/Length` is the compressed
length, and a second independent review measured a 408 516-byte PDF
declaring a 1x1 picture and carrying 400 MB of deflated zeros being
CARRIED, with no rejection, at 892 MB of peak RSS. With the bound: 0
carried, `asset_too_large`, 54 MB — and 62 MB where the old path cost
2 436 MB, so the cost no longer scales with the bomb.
- **Every link of the chain is measured, not only the first.** A PDF
decodes a stream through a list of filters, and the first fix read
`filters[0]`: `/Filter [/FlateDecode /FlateDecode]` therefore cost
886 554 624 bytes of peak RSS from 1 636 bytes of file, and three links
cost the same from 1 070 — about 542 000x, with the picture still refused
at the end, after the memory had been spent. It also left the 16 corpus
image objects behind an `[/ASCII85Decode /FlateDecode]` chain unmeasured,
because `filters[0]` is not `FlateDecode` there. Bounded, measured idle in paired subprocesses: 52 367 360 bytes at two
links, 61 390 848 at three, and 60 403 712 where the old path cost
2 567 204 864.
- **What a link COSTS is bounded, not the size of its output.** Bounding
every `FlateDecode` was still not a bound: the bomb moved into
`ASCII85Decode`, which the previous fix had classed as safe "because it
shrinks". `z` is that encoding's shorthand for four zero bytes, so the
filter quadruples its input, and `base64.a85decode` appends one 4-byte
object per group to a list — about a hundred bytes of memory per byte of
INPUT (measured on CPython 3.14: 101.4x at 1 MiB, 96.1x at 4 MiB, 94.5x at
16 MiB). Measured in paired subprocesses, idle machine, the document built
once and read from a file: a 33 475-byte PDF decoding through
`[/FlateDecode /ASCII85Decode]` cost 3 261 599 744 bytes of peak RSS and
the picture was CARRIED; bounded, 42 070 016 and `asset_too_large`.
Doubling the run of `z` takes the old cost to 6 461 558 784 and the
bounded one to 40 280 064, so the cost no longer follows the bomb. A
single `[/ASCII85Decode]` link went 933 085 184 → 62 484 480, and
`[/Fl /A85 /Fl]` 3 519 180 800 → 43 438 080 (and from
`asset_samples_invalid` to a bound's own code).
- **Every permitted filter now carries a measured cost ratio**
(`assets.PDF_FILTER_COST_RATIO`) and a per-link budget
(`MAX_FILTER_DECODE_BYTES`, 512 MiB). `FlateDecode` is measured a chunk at
a time as it is paid, under a limit that is the smaller of the picture's
own bound and what the NEXT link's decoder may be handed, so the budget
travels down the chain. Every other permitted filter has its cost
PREDICTED from its input size before its decoder is called, because those
decoders take a whole string and return a whole string. The cap that falls
out for `ASCII85Decode` is read off the corpora: of the 9 668 image
objects of the 77 PDFs measured, 16 decode through such a link and the
largest input to one is 450 739 bytes, more than ten times under it.
- **A filter with no measured ratio is refused unread**, with its own code
`asset_pdf_unbounded`: `LZWDecode`, `RunLengthDecode`, `CCITTFaxDecode`,
`/Crypt` and anything unknown.
- **A property test runs every chain of length 1–3** over the ten filters
pdfminer decodes — 1 110 of them, each with an amplifying payload —
and requires each to be delivered under the bound or refused with a code
in the published vocabulary, never paid for on the way. The known-positive
beside it holds that every chain over the permitted filters still carries
a small image. Over the 5 142 image objects of
the 78 PDFs measured, the refused class is 4 `CCITTFaxDecode` objects,
which are 1-bit stencil masks and were already refused one step later by
the encoder. Measured by name over the same 78 documents, carried images
are 9 356 before and 9 356 after: no document loses a picture, and the 8
objects that move code (4 masks, counted twice) were refused on both sides.
- **An encrypted stream is deciphered and then measured.** Deciphering does
not change a stream's length, so this does what pdfminer's own `decode()`
does; before, `stream.decipher is not None` returned without measuring,
which made "the document declares encryption" a way past the bound.
- What remains outside the bound is a stream something else has already
decoded, where the memory is spent before this package is asked. That one
is caught by a check on `len(data)` AFTER `get_data()`, which is a counted
refusal and not a bounded one. The difference is stated in the code rather
than implied — and, since this change, held by a test: deleting exactly
that line passed all 2 132 tests before it.
- **A declared size that is not a size is refused with its own code
(0.10.1).** `/Width -1 /Height 40000000000` multiplies to a NEGATIVE pixel
count, under which every bound read as satisfied: the check returned
silently, 400 MB was decompressed, and the refusal arrived from the PNG
encoder as `asset_samples_invalid` — a code about a sample buffer for a
defect in the declaration. A non-positive dimension is now `asset_size_invalid`,
raised before the stream is read. Its own code because a legitimate
publisher shipping a picture larger than this package carries and a
dictionary written to be read wrong are different facts about a document.
### Fixed
- **The retrieval gate had to resist the work it judges: four of eight
cheating attacks went through it, and they are closed (2026-09-19).** PM's
checkpoint on `2c8296b` took rows 3, 5, 7 and 8 GREEN without one label
becoming true or one concept ranking better. An eval written before the
capability has one job beyond being red today, so the gate was repaired
before anything is built against it. `src/` is untouched.
- **Row 8 requires all three named sets** (`wiki-20`, `r761-sk2`,
`vegnormal-32`) and is NOT RUN otherwise. It counted whatever `--real`
gave it, so one set of three read `6 of 6 GREEN` — and this repository's
own test asserted `(1, 1, GREEN)` for a single set. The numbers the run
DID measure are still printed: a missing set must not cost the reader the
set that was measured.
- **Its headline is at QUESTION granularity**, and was `quoted + concept`
over `quoted_units + concept_units` on the line above the detail saying
the two are not summed. The three sets share no unit — a citation, a
section title and a requirement number — so their sum is a number that is
none of them.
- **Rows 2 and 3 take their denominator from the pinned set, not the run.**
At `k = 32` the fixtures declaring class b are delivered, and they used to
leave the denominator: rows 1, 2, 3 and 6 all read green at once. A forced
fixture that stops producing its declared class is a BROKEN PREMISE now,
printed as one and counted against its row.
- **Row 3 carries a known-positive.** With `--source-quota` off every
printed reason is true — not a lie, an empty measurement — so a set may
declare `source_quota_in_force` and the row is NOT RUN for it when the
default and quota-off cuts deliver the same concepts. **The control's own
premise was measured first and was false where it was first put:** over
the five existing sets the two cuts deliver the SAME concepts (the quota
is topped back up), 52 labels moving `source_quota_exceeded` → `below_k`
with 0 deliveries changing. `set-quota.json` is the one set where the
quota genuinely decides.
- **Row 5 reads git for the half a registration cannot assert about
itself.** Two files PM wrote in the moment came back `7 of 7 GREEN`. Three
of its ten checks now read history: committed and unmodified, its commit
is not itself a ranking change, and a ranking change landed AFTER it —
the last being the one that cannot be self-attested. What git cannot prove
(that nobody read the number first) is stated in the row.
- **Row 7's roster is pinned apart from the list it names.** The bar is a
share, so seven duplicate `k = 1` mutants read `18 of 20 GREEN` with the
same two survivors. `MUTANT_ROSTER` and `MUTANT_COUNT` are separate
constants, duplicates are refused, and the bar is the roster's length.
- **The synthetic corpus is pinned like the sets** (`SPECS_SHA256`). A tuned
corpus was caught by row 2's forced classes and not by a pin.
- **`M14` closes PM's G9**: `hit = bool(hit_ids) and bool(confirmed)` is
reached only by a delivery that still carries the citation and is no
longer the concept file's bytes. It is felled and no production line
changed — the term was observable and unobserved. The judge's
independence is measured with it: index warmed BEFORE the patch, every
unit a miss; index built UNDER it, every unit a hit. The gate never builds
one under a mutation, and that is in `LIMITS`.
- **Row 9 takes `--k2 SET SHA256 BUNDLE`** in this gate's own set shape, and
a set of another size is refused as another set wearing K2's name. Without
one it stays RED rather than NOT RUN: its denominator is known.
- **Row 8 ran, against all three real sets**: **44 of 64 questions**, 7 of
29 at citation granularity and 38 of 50 at concept granularity, 33 of 34
misses class b. wiki (6 of 20) and r761 (7 of 7) reproduce PM's recorded
figures exactly; vegnormal measures 31 of 43 citations where PM recorded
32, a one-citation disagreement between two instruments over the same
pinned bytes, stated and not resolved here.
- Rows 1 and 6 go 9 of 9 to 10 of 10 (one added fixture, one added hit).
Every other row is unchanged and the verdict is unchanged:
`GATE RED: rows 3, 4, 5, 7, 8, 9`, exit 1, byte-identical over two runs.
`mypy --strict` on the gate goes 8 errors to 0. Report:
[`docs/2026-09-19-gjenfinningsgaten-motstand.md`](docs/2026-09-19-gjenfinningsgaten-motstand.md).
- **The conversion claim the content-accounting gate believes now comes from
the RUN, not from the bundle's prose (0.10.1).** The previous round bound
the claim to a pointer block, which closed the two forgeries PM had
measured and did not close the class: a pointer block is two lines of
markdown, and one ordinary HTML file with two `<p>` elements writes them.
Reproduced through the real `okf build` — a BMP refused `asset_too_large`
and absent from `assets/` read as CARRIED, from a document naming one
digest that is public in the bundle and one that is computable in advance.
- `okf build --accounting` now books every conversion the run performed:
`assets.conversion` names the `(source digest, asset digest)` pair,
`DocumentAssets.conversions` carries it out of the run and the accounting
JSON states it per document as `conversions: [{from, to}]`.
- The gate reads the pair from there and uses the bundle text only to
CONFIRM it. The confirmation can be forged and the ledger cannot, which is
why the ledger decides.
- **Chosen over neutralising pointer-shaped text at extraction**, because
that fix changes what every document SAYS in order to defend a tool
outside the build: a source quoting a bundle listing would come out
altered and existing bundles would move bytes.
- A build run with no accounting door has no ledger, so a converted image
is reported claimed-and-not-found rather than believed. That is the same
reading the gate had before the conversion route existed.
- Measured: the three arms PM reproduced go forged → refused, 3 of 3, with
the known-positive (a BMP the run really does convert) True in all three.
The text-level regression guard goes 3 arms to 13. R761 rebuilt is
`diff -r`-identical, 50 assets (29 JPEG + 21 PNG), 19 of 19 conversions
confirmed against 19 declared, SHY 71, u = 0, d = 0.
- **An RLE8 stream that stops before the frame is refused (0.10.1).** The
terminator rule added earlier in this version asks only that a stream SAY it
is finished, and a stream can say so anywhere: measured 2026-09-19, one
whose FIRST two bytes are the end-of-bitmap escape was carried with 32 of 32
pixels never decoded, while an independent decoder refuses the same file.
`_bmp_rle8_rows` now also requires the cursor to stand at or past the end of
the last row (`asset_samples_invalid`).
- **The line is the cursor and not the pixels.** A delta escape and an
end-of-line escape state their skip, so the pixels they pass over keep
index 0 and every decoder produces the same picture; a pixel-coverage
count would refuse both constructions the format defines. The corpus
cannot choose between the two rules — over the 25 RLE8 BMPs the R761
delivery ships, 25 of 25 paint every pixel, 25 of 25 reach the end of the
frame and 0 of 25 use a delta — and an independent decoder can: Pillow
reads 5 of the 8 streams in the table and refuses the same 3 the new rule
does, one of them short by a single pixel.
- Two docstrings this round was sent to correct are rewritten: the test no
longer claims every pixel is decoded, and `_bmp_rle8_rows` no longer
frames the delta argument as read off the corpus, which it never was.
- **An end-of-line escape at column 0 states no skip, and neither does a delta
out of its row (0.10.1).** The entry above says a delta escape and an
end-of-line escape both leave pixels every decoder agrees on. Measured by PM
and reproduced here: that is true of the delta and false of the end-of-line.
Four end-of-line escapes and an end-of-bitmap carried an 8x4 frame with 32 of
32 pixels never decoded, and Pillow refuses those same bytes.
- The class is wider than the one construction, and this round measured it
rather than patching it: over every opcode sequence of length 1 to 4 on a
4x3 frame — **22 620 streams**, swept in the suite — this package carried
**703** streams the independent decoder refuses and drew **1 492** more
differently. PM's recommendation on its own (refuse a stream that painted
nothing) leaves **512** and **1 171** of those, so it would have narrowed
the class for the third round running.
- `_bmp_rle8_rows` refuses an end-of-line escape at column 0 (it closes no
row, so the row it passes over is one the stream never wrote) and a delta
whose horizontal offset would leave the row (the format puts that offset
inside the line; this reader keeps the cursor past the row end and a flat
decoder rolls it into the next row). Both with `asset_samples_invalid`.
After: **0** carried-here-refused-there and **32** drawn differently.
- **What is not closed is stated.** All 32 residual streams are a run or
absolute block that OVERRUNS its row. Refusing those gives 0 and 0 — and
costs **15 of the 25** real RLE8 files, which would drop 15 real figures
and move a pinned bundle's bytes.
- **Cost measured on the corpus first:** over **11 441** files scanned across
the four raw standard deliveries and the K2 reference corpus, the only
**25** BMPs on this machine use an end-of-line at column 0 in **0 of 25**
and a delta in **0 of 25**, and **25 of 25** still decode to Pillow's
pixels exactly (**3 117 220** pixels compared) after the change.
- `CURSOR_CASES` goes 8 arms to 12: one for the cursor rule's ROW clause
(PM's `P8`, `height - 1` → `height - 2`, which survived 51 tests) and four
for the end-of-line class. `P8` and `P13` join the mutant runner.
- **The published `--accounting` contract names every key the gate reads
(0.10.1).** The JSON sketch in `tools/okf_accounting_gate.py` is what a
consumer implements the door from, and it did not name `conversions`, which
`asset_holds`' conversion route depends on, nor `normalised_soft_hyphen`,
`unaccounted` or `double_booked`, which the door had written for a round
longer. A door built from the contract writes a ledger the gate reads as
"nothing was converted", and every converted image comes out
claimed-and-not-found — 19 of 50 on R761. Two tests hold the sketch against
both sides: what the gate LOOKS UP (measured with a ledger that records its
own lookups, not by grep) and what the door SERIALISES.
- **A bundle built without the door now says why a converted image cannot be
proved (0.10.1).** Without `--accounting` there is no ledger, so `asset_holds`
falls back to its first route and a converted picture is counted
claimed-and-not-found. The fallback was honest and silent; the count was
printed and its cause was not. `_tally` names the missing ledger when, and
only when, something was claimed and not found, and `asset_holds` says it in
its own docstring. The gate always passes the flag, so no row moves.
- **The published `tbx:` count is one number, guarded without the delivery
(0.10.1).** `assert sum(tbx.values()) == 568` sat behind a `skipif` on a file
only one machine has, so on a fresh clone the sentence five files publish was
unguarded — the state in which 574 survived in four docstrings. `N101_TBX_TAGS`
is now the one place it lives and a second test holds all five published
sentences to it, with no corpus and no clock. What it does not prove is
stated: five files agreeing is agreement, not a count.
- **The mutant runner judges a mutant by the suite that owns it, and the
catalogue goes 39 to 45 (0.10.1).** It could only run one test file, which is
why PM's three survivors from `43331fc` could not be added. `X3`/`X4` were
rewritten against the code as it now stands; `X6` is the defeated state
exactly (a pointer block believed without the run having booked it); `X7`
cuts the ledger off at its source; `X8` removes the cursor rule; `P6`, `P11`
and `P12` are PM's three. Two survivors appeared on the first run and both
were findings — the asset binding had stopped being exercised, and the
`_inline` disarming survived the WHOLE suite (2134 passed) because the gate
no longer reads its claim from the bundle. The disarming is KEPT and now
measured in `tests/test_assets.py`: the property is about the bundle, not
about one judge. `killed 45 of 45`, exit 0.
- **`test_the_four_existing_goldens_are_untouched` skips, with its reason, in
a `git archive` extract (0.10.1).** It called `git status` with `check=True`
outside a repository and raised. It was the single failure of the whole
suite run from a clean extract, twice reported as a round's one failure by a
round that had not touched the file.
- **A truncated RLE8 BMP is refused instead of carried as a partly blank PNG
(0.10.1).** `_bmp_rle8_rows` painted what the stream held and left the rest
of the frame at palette index 0 — which is what the format says about a
SKIPPED pixel, so no decoder disagreed and the picture was wrong with no
code and no row. Measured by PM 2026-09-19 on a real R761 asset (352x548 =
192 896 pixels): cut to 90 % it was carried with 13 923 pixels wrong, to
50 % with 95 890, to 10 % with 166 525. The uncompressed path already
refused the same shape.
- The decode may now end at an explicit end-of-bitmap escape and nowhere
else; running out of bytes raises `asset_samples_invalid`, the code the
uncompressed path uses. NO PIXEL IS GUESSED: either every one is decoded
from the stream, or the picture is refused with a line in the concept.
- The rule is the terminator rather than `biSizeImage` (a claim by the same
untrusted header) or a coverage count (which would refuse the delta escape
the format defines), and it is read off the corpus: over the 19 real RLE8
assets of the frozen R761 delivery, **19 of 19** end at an explicit
end-of-bitmap, on **19 of 19** it is the stream's last two bytes, and on
**19 of 19** `biSizeImage` equals the available bytes. A whole stream that
omits the terminator is refused alongside a cut one.
- **Nothing real changes hands:** the same 19 files still convert losslessly
after the rule, **2 366 365 pixels** compared — this time with stdlib on
BOTH sides, an independent BMP reader and an independent `zlib` +
filter-reversal PNG decoder, with a one-byte control proving the
comparison can fail.
- **The content-accounting gate: a document refused whole is never clean.**
Its elements are all booked as coded rejections, so u = 0 and d = 0, and
`refused_whole` asks its question only for a corpus that persisted NOTHING —
one refused source beside an accepted one read as clean with the content
gone. `Unit.refused` is that loss with its own column and the document's code
in the note.
- **The STS JSON role map reads the publisher's own tags.** `count_sts_json`
compared the raw tag string where the XML witness has always used `_local`,
so `mml:math` reached `tag == "math"` on nothing — 74 formulas in N200
Vegbygging:2024 counted as 0. And the publisher's JSON writes a figure's
caption as `figcaption` under the `graphic`, not as the `fig/caption`
NISO-STS writes — 430 of them over the eight deliveries measured. No other
count moves, measured role by role over those eight and the committed twins.
- **The mutation harness is a gate.** A surviving mutant now exits 1; the run
ended `2 if errors else 0`, so `killed 0 of 1` exited 0. PM's X2 mutant — a
report may declare a document rejected while the bundle holds it — is in the
set and is killed by a new test driven from both sides.
- **The skipped-row guard measures the machine, not the argument.** Row 6 is
SKIPPED exactly when the corpora the arguments name are absent, so asking the
arguments made the branch unreachable.
- **Row 6 says when a corpus measures no element class at all.** On N200 the
build proposes 0 plans and exits 2 before the accounting door, so 16 549
elements land as unaccounted with no declared fate — a finding about the run
that read as a finding about the build.
- **An inline PDF image gets a stable name (0.10.1).** pdfminer names an
inline image (`BI … EI`) from `id()` of a Python object, so a pointer line
changed between two runs of one build and two concept files of the reference
corpus differed — breaking the bit-exact rebuild invariant. Such an image is
now named from its position on the page.
- **Three sentences this release publishes are now held by tests.** PM's
checkpoint on `43331fc` found three mutants surviving the entire suite: a
normalisation door that ALSO removes U+00A0 NBSP — which would have eaten
all 6 633 of them in R761 while `log.md` went on saying "No other character
is touched" — and row 3 of the accounting gate losing either its
`refused={n}` column or its "N element(s) lost with R of D document(s)
refused whole" clause. Each is killed now by a test that counts its own
numbers: ten characters the door must leave exactly where they were
(compared against a filter written in the test, so ORDER is pinned as well
as multiset), and R, D and the element total counted over the units the test
builds.
- **`log.md` says where the soft-hyphen count comes from.** The
`**Normalisation**` bullet now ends "The count is the door's own, read off
the run and not recounted from the source." Chosen over adding a second,
independent counter: the door acts on the EXTRACTED text, so a counter over
the source bytes would disagree by construction on every type extraction
does not carry verbatim, and the gate would have to decide which difference
was a loss.
- **Two published numbers were wrong and are corrected.** N101 ships **568**
`tbx:` tags, not 574 — three independent counts agree (raw substring, regex
over the JSON `tag` field, node traversal), and a test now counts them over
the delivery instead of repeating the number in a fourth docstring. And the
reach clause "0 across `tests/fixtures`, `examples`, …" was true only of
U+00AD: **2 of 230** readable tracked files carry U+200B, this repo's own
known-negative fixture, which the door is built not to touch.
### Documented, not changed
- **The accounting gate proves CARRIAGE, not FIDELITY.** Neither of
`asset_holds`'s routes decodes a pixel: a converter writing a blank PNG is
accepted, because the bundle is internally consistent. The suite fells that
mutant by decoding both sides; the judge cannot, and its docstring now says
so — "claiming a conversion it did not perform" means claiming one whose
FILE is missing, never one whose pixels are wrong.
- **The lossless guard now has an arm that runs on a core install.** It decoded
through Pillow, an OPTIONAL dependency here (transitive under `pdfplumber` in
`[extract]`), so 4 of the 13 guards in `tests/test_asset_viewable.py` were
SKIPPED on a plain `pip install llm-ingestion-okf` — the lossless one among
them. The new arm decodes the carried PNG with `zlib` and the five PNG SS 9.2
filters and compares against pixels written out in the test file, and it is
re-run under a `sys.meta_path` finder that makes every `PIL` import fail.
- `images: N` in a concept counts POINTER BLOCKS, not unique pictures (12
pointers to 2 files is `images: 12`). Now stated in the README.
- A concept that is only a pointer block is persisted as substantive, because
"degenerate" means zero characters after stripping whitespace and a pointer
block is text.

**AND THAT GATE WAS SILENT ABOUT WHAT IT DROPPED, UNTIL v1 (2026-09-20).**
Naming the gate in `log.md` said which screen ran; it did not say what the
screen took. Measured at the shipped default against a real corpus of official
documentation: `guard-trusted-source` refused a minority of sources OUTRIGHT,
under `fail_secure` and `quarantine_review`, and most of those were ordinary
reference pages. Rebuilt with `--gate none`, every one of them went through
untouched, so the refusal is the GATE and not the readers: official
documentation naturally carries commands and instruction-shaped text, and the
guard reads that as something to hold for review. The summary printed one
`` `fail_secure`: N/D `` line and nothing else, so **three of the four facts a
reader needs were absent**: the COUNT of documents the gate dropped (the existing `rejected
(coded)` line SUMS gate refusals and extraction failures -- two failures with
two different remedies, which is why `gate_refused` is its own column on
`CorpusReport`), the NAMES, and the way out. `corpus.REFUSED_HEADING` now opens
a section carrying all four, directly under the denominator, and
`refusal_banner()` says the same thing in one line on stderr because `okf build
> report.txt` is ordinary; both read the SAME field, so the loud line and the
summary cannot come to disagree about a number. The per-name list is capped at
`REFUSED_NAME_CAP` = 10 and `log.md` gains one bullet naming **every** refused
document, uncapped -- a cap is only honest if the rest is somewhere a reader can
go, and §9 already holds the one fact about a run the bundle cannot otherwise
recover. **THE EXIT CODE DOES NOT MOVE**: the build is valid, every refusal is
coded, the conservation identity holds, and the bundle is a true record of what
the gate allowed; what was wrong was the silence, not the status. A run the gate
refused nothing from is byte-identical in both places -- the known-negative in
`tests/test_gate_refusal_is_loud.py`, and the reason this cannot have moved a
byte measured here: **0 of the bundles this repository ships** was built with a
gate refusal. The gate's SEMANTICS are untouched and the guard is not touched
from here (another repo, another release, its own security assessment); that a
trusted-source tier should CARRY a `quarantine_review` document marked rather
than throw it is a candidate for the round after v1, not work.

K2 bundles**, so the default move cost the retrieval side nothing.
- **The image path has a size CEILING and no live links (0.10.1).** TWO
independent reviews, a day apart. The first found two MAJOR defects in
`v0.10.0`, both with the shipped defaults, both new in 0.10.0. The second
read the fix for them and found that ONE of the two was not closed --
which is why the version below is 0.10.1 and not 0.10.0 with a patch note.
- A remote `<img src>` / `xlink:href` became a LIVE markdown image link in
the persisted concept. This package opens no socket; a consumer that
renders the bundle does, and the guard refuses such a line at
`user-upload` while the build's default tier persisted it. Now inert text
with the address in a code span, pinned by a PROPERTY over the readers
(`FOREIGN_IMAGE_LINK`), never one string.
- **THE FIRST FIX FOR IT WROTE THE ADDRESS TWICE**, once in a code span and
once BARE, and a GFM/linkify renderer autolinks a bare URL. Weaker than an
image link -- it takes a click -- but "inert" was half true. It also
dropped the figure's CAPTION: `label` stayed in the signature and no
branch read it, so an image the bundle does not carry lost the one fact
that lets a reader weigh the absence. Both closed; the caption is written
in the same `-- <label>` form a carried pointer uses.
- **NOTHING BOUNDED WHAT THE RUN PAYS, only what the document CLAIMS.**
`MAX_IMAGE_PIXELS = 40 000 000` and `MAX_IMAGE_BYTES = 256 MiB` were
checked against `/Width` x `/Height`, which is an untrusted document's
claim, while `get_data()` pays for the actual stream -- two independent
numbers, since `/Length` is the COMPRESSED length. Measured by the second
review: a **408 516-byte** PDF declaring **1x1** and carrying 400 MB of
deflated zeros was CARRIED, no rejection, **892 MB peak RSS**, and 1,2 GB
of zeros cost **2 436 MB** -- about 2 100x the file size, linear. The
first fix's four mutations all died, because not one of them separated
declared from actual.
- **THREE NUMBERS ARE BOUNDED NOW.** What the container DECLARES (as
before), what a carried FILE measures (`read_image`, so a 49 MP PNG of
47 705 bytes is not passed on to the consumer with `7000x7000 px` beside
it), and what a PDF image's STREAM decompresses to -- measured a chunk at
a time and DISCARDED, before `get_data()`. With it: **0 carried,
`asset_too_large`, 54 MB** at 400 MB and **62 MB** at 1,2 GB, so the cost
no longer scales with the bomb.
- **THE CHAIN, NOT ITS FIRST LINK.** That fix read `filters[0]`, and a PDF
decodes a stream through a LIST of filters: measured 18.09 on `0f308c1`,
`/Filter [/FlateDecode /FlateDecode]` cost **886 554 624 B peak RSS from
1 636 B of file** and three links the same from 1 070 B -- about
542 000x -- with the picture still refused at the end, by the backstop,
after the memory was spent. It also left the **16** corpus objects behind
an `[/ASCII85Decode /FlateDecode]` chain unmeasured, since `filters[0]` is
not `FlateDecode` there. Bounded (idle machine, paired subprocesses):
**52 367 360 B** at two links, **61 390 848 B** at three, **60 403 712 B**
where the old path cost 2 567 204 864 B, and the single-link control
unmoved at 59 232 256 -> 62 017 536. Everything
else -- `LZWDecode`, `RunLengthDecode`, `CCITTFaxDecode`, `/Crypt`,
anything written later -- is refused UNREAD with its own code
`asset_pdf_unbounded`, the same decision `corpus.resolve_gate` takes for
an unknown gate name. **The three-class split this round shipped with --
`ASCII85Decode`/`ASCIIHexDecode` "bounded by their own input because they
SHRINK" -- was FALSE and round 3 below replaced it.** Cost measured over the **5 142** image objects of
78 PDFs: the refused class is **4** `CCITTFaxDecode` objects, all 1-bit
stencil masks already refused one step later by the encoder, and **0**
objects in an encrypted document. **NOT ONE PICTURE CHANGES HANDS AND IT
IS MEASURED BY NAME**: over the same 78 PDFs, carried images are
**9 356 -> 9 356**, **0 of 78** documents lose one and 0 gain one; the
only movement is **8** objects going `asset_pdf_unsupported` ->
`asset_pdf_unbounded` (the 4 masks, counted twice because `trinn1` and
`trinn2` hold the same document). An ENCRYPTED stream is
now deciphered and then measured (deciphering does not change a length),
where `stream.decipher is not None` used to return unmeasured.
- **THE COST OF A LINK, NOT THE SIZE OF ITS OUTPUT (round 3).** Three
rounds each bound an OUTPUT and the bomb stepped one link along: the
declared size, then the first `FlateDecode`, then every `FlateDecode`.
Round 2's third class was FALSE -- `ASCII85Decode`'s `z` is the shorthand
for four zero bytes, so it QUADRUPLES its input, and `base64.a85decode`
appends one 4-byte object per group to a list, costing about **a hundred
bytes of memory per byte of INPUT** (measured on CPython 3.14: **101.4x**
at 1 MiB, **96.1x** at 4 MiB, **94.5x** at 16 MiB). Paired subprocesses,
idle machine, both sides from pinned trees, the document built once and
read from a FILE because `ru_maxrss` never falls and `b"z" * 64 MiB`
alone costs 171 MB: `[/Fl /A85]` **33 475 B of file -> 3 261 599 744 B
peak and the picture CARRIED**, now **42 070 016 B** and
`asset_too_large`; at twice the `z` run **6 461 558 784 -> 40 280 064**,
so the cost no longer follows the bomb; `[/A85]` alone **933 085 184 ->
62 484 480**; `[/Fl /A85 /Fl]` **3 519 180 800 -> 43 438 080** and from
`asset_samples_invalid` to a bound's own code. **The rule is a BUDGET per
link** (`assets.MAX_FILTER_DECODE_BYTES`, 512 MiB, a separate number from
`MAX_IMAGE_BYTES`): `FlateDecode` is measured as it is paid, every other
permitted filter has a MEASURED cost ratio
(`assets.PDF_FILTER_COST_RATIO`) checked against its input BEFORE its
decoder is called, and a filter with no ratio is refused unread. **The
budget TRAVELS**: a deflate link is inflated under the smaller of the
picture's bound and what the next link's decoder may be handed, or
`[/Fl /A85]` pays 256 MiB for a refusal. The ASCII85 cap (**~5.0 MB**) is
READ OFF the corpora: of **9 668** image objects over **77** PDFs, **16**
decode through such a link and the largest input is **450 739 B**, ten
times under it. **A PROPERTY TEST replaces the list of known shapes**:
every chain of length 1-3 over the ten filters pdfminer decodes, **1 110
of 1 110**, both payload fills, each delivered under the bound or refused
with a published code and never paid for on the way (`tracemalloc`, which
counts allocations and is not disturbed by load). Known-positive: **258 of
258** chains over the permitted filters still carry a small image.
**10 of 10 mutants killed**, control green. **NOT A ROW'S DIFFERENCE ON
REAL DOCUMENTS**: paired `_pdf_images` over every PDF on this machine from two PINNED trees: **9 306 -> 9 306** bårne over 77 filer plus **50 -> 50** on R761 (**9 356 -> 9 356** together), **0 of 78** files moving a count and **0** moving a code. R761 also settles the `[/Fl /A85]` question: **50 objects, 29 `[/DCTDecode]`, 21 `[/FlateDecode]`, 0 ASCII85 links** -- round 2's count of **580** is reproducible from nothing on this machine, which changes no decision but should not stay unqualified. **`resource.setrlimit(RLIMIT_AS)` was
MEASURED before anything was built on it and is NOT usable here** --
Darwin 26.6.2 raises `ValueError: current limit exceeds maximum limit` and
does not enforce it -- so no child-process cap exists and the per-link
budget is the whole bound. Report:
`docs/2026-09-18-utgangsbudsjett-per-ledd.md`.
- **THE LIMIT IS STATED RATHER THAN IMPLIED, and it is now ONE case**: a
stream something else has ALREADY decoded, where the memory is spent
before this package is asked. `check_payload(len(data))` after
`get_data()` COUNTS it -- a counted refusal, not a bounded one. Deleting
exactly that line passed all **2 132** tests on `0f308c1`; it has a test
now.
- **A non-positive declared dimension is `asset_size_invalid`**, its own
code, raised before the stream is read. `-1 x 40 000 000 000` is a
NEGATIVE pixel count, under which every `>` bound reads as satisfied: the
check returned silently, 400 MB was decompressed, and the refusal came
from the PNG encoder as `asset_samples_invalid`. Its own code because a
publisher shipping a picture bigger than we carry and a dictionary written
to be read wrong are different facts about a document.
- **An inline PDF image is named from its position, not from `id()`** —
pdfminer's name broke the bit-exact rebuild on two K2 concepts.
- Documented rather than changed: `images: N` counts POINTER BLOCKS, and a
pointer-only concept is substantive.
- Reports: `docs/2026-09-17-bildestien-0-10-1.md` and
`docs/2026-09-18-bildestien-holder-0-10-1.md`.
- **EVERY CARRIED IMAGE IS ONE A MODEL CAN BE SHOWN (0.10.1, 2026-09-19).**
Until this round the path carried whatever a publisher shipped. Measured over
the frozen R761 delivery's own `assets/`, denominator 50: 29 JPEG, 2 PNG and
**19 "PC bitmap, Windows 3.x, 8-bit, compression 1"** -- byte-correct RLE8
BMP files that nothing reads, so 19 figures were present and invisible at
once while `images: N` said they had arrived. `assets.VIEWABLE_MEDIA_TYPES`
(`png`, `jpeg`, `gif`, `webp`) is tested against every asset's SNIFFED type,
so it is a PROPERTY and not a list of formats we met; WebP is on it and
`sniff` does not recognise one, which is stated rather than implied. BMP is
converted losslessly to PNG -- 8-bit uncompressed, 8-bit RLE8 and 24-bit
uncompressed -- and everything else outside the set is refused with
`asset_not_viewable`, a BMP variant this reader does not express with
`asset_bmp_unsupported`, both leaving the concept's own "not carried" line.
**THE READER IS STDLIB AND PILLOW WAS MEASURED AND FELLED**, though the tree
already carries it transitively under `pdfplumber`: `read_image` is on the
CORE path (`.html` and `.xml` carry images with no `[extract]`), and an
asset's name is its content digest, so encoding through an installed library
would make a bundle's identity move with that library's version -- 0.10.0's
own reason for felling page rasterisation. Pillow is the INDEPENDENT decoder
in the tests instead, and against it **19 of 19** real RLE8 assets convert
with identical RGB, **2 366 365 pixels** compared. The ceiling is paid on the
DECLARATION before a row is allocated, and an RLE run is one CLIPPED slice --
painting pixel by pixel leaves the memory bounded and the CPU unbounded, a
megabyte of `FF` runs being a hundred million steps against a 32-pixel frame.
Traceability is on the pointer's second line where the rest of the asset
metadata already lives (original media type, original sha256 in full, new
sha256), and a converted asset is ONE asset: one file, one pointer, one
accounting row. Exposure measured with a committed script
(`tools/okf_asset_census.py`, one row per image, run from two pinned trees
over 18 403 files and 67 PDFs, **9 714 image rows**): exactly **35 rows
moved**, **9 321 of 9 321** JPEG and PNG rows byte-identical, so not one
already-viewable picture changed hands. **16 of the 35 are the finding the
round did not go looking for**: JPEG 2000 objects out of PDF streams, a
format no model decodes and no stdlib route converts, so they go from
carried-and-invisible to `asset_not_viewable` with a line in the concept --
a consumer loses 16 pictures and gains 16 statements that a picture was
there. **The judge had to move with it and it caught itself**: the gate's
`asset_holds` proved a carry by hashing the SOURCE file, which a converted
image's bundle cannot satisfy, so R761 went 0 -> **19 claimed and not
found** (exactly its RLE8 count) before the judge learned to read the two
digests the bundle states and then hash the asset itself; after, R761 is
u = 0, d = 0, 0 claimed and not found, 50 asset files, 31 081 carried
elements, and the gate's verdict is the same `RED: rows 2, 3, 6` as before
the round. Report:
`docs/2026-09-19-hvert-baaret-bilde-kan-vises.md`.
**THAT ROUND SHIPPED TWO DEFECTS AND 0.10.1 CLOSES THEM.** A TRUNCATED RLE8
stream was carried as a partly blank PNG: the decoder painted what the
stream held and left the frame at index 0, which is what the format says
about a SKIPPED pixel, so no decoder disagreed -- measured on a real R761
asset of 192 896 pixels, a stream cut to 90 % was carried with 13 923 pixels
wrong, to 50 % with 95 890, to 10 % with 166 525, no code and no row. The
decode may now end at an explicit **end-of-bitmap escape and nowhere else**
(`asset_samples_invalid`, the code the uncompressed path already uses), and
the rule is the terminator rather than `biSizeImage` -- a claim by the same
untrusted header -- or a coverage count, which would refuse the delta the
format defines: over the 19 real RLE8 assets **19 of 19** end at an explicit
EOB, on **19 of 19** it is the last two bytes, and on **19 of 19**
`biSizeImage` equals the available bytes, so the same 19 still convert
losslessly, 2 366 365 pixels, now with stdlib on BOTH sides. And the JUDGE's
new conversion route could be **FORGED BY THE DOCUMENT**: it read the two
digests out of the WHOLE bundle text, so a BMP refused `asset_too_large` and
absent from `assets/` was reported as held, through an image's `alt` text
and through ordinary body text alike. The claim now counts only inside a
POINTER BLOCK this code wrote and only where it names that block's own
asset, and `assets._inline` disarms a checksum field in anything that came
from the document -- **the boundary is that everything `_inline` returns
came from the document and everything `render_block` appends after it came
from the run**; neither half is sufficient alone. The gate proves CARRIAGE
and not FIDELITY, which its docstring now states: a converter writing a
blank PNG is accepted, the suite fells that mutant and the judge cannot.
Report: `docs/2026-09-19-bmp-resten-terminator-og-pekerblokk.md`.
**AND THAT ROUND NARROWED BOTH DEFECTS WITHOUT CLOSING EITHER.** A POINTER
BLOCK IS A FORM AND A FORM IS NOT A SIGNATURE: measured through the real
`okf build`, one ordinary HTML file with **two `<p>` elements** writes the
two lines `_POINTER` matches, and the same refused BMP read as held again --
also with `<p>`+`<br>`, and with a markdown note beside the HTML carrier,
**3 of 3**. So the pair is read from the RUN's own ledger (`--accounting`
now books `conversions: [{from, to}]` per document, off `assets.conversion`)
and the bundle text only CONFIRMS it: the confirmation can be forged and the
ledger cannot. **Chosen over neutralising pointer-shaped text at
extraction**, which would change what every document SAYS to defend a tool
outside the build. A build with no accounting door reports a converted image
claimed-and-not-found rather than believing it. Measured: 3 of 3 forged ->
refused with the known-positive True in all three, the text-level regression
guard 3 arms -> 13, R761 rebuilt `diff -r`-identical, 50 assets, **19 of 19**
conversions confirmed against 19 declared, SHY 71, u = 0, d = 0. And the
TERMINATOR asks only that a stream say it is finished, which it may do
anywhere: a stream whose FIRST two bytes are the EOB escape was carried with
**32 of 32** pixels never decoded while Pillow refuses the same file. The
cursor must now also stand at or past the end of the last row. **The line is
the CURSOR and not the pixels** -- a pixel-coverage count would refuse the
delta the format defines. The corpus cannot choose (over the **25** RLE8
BMPs the delivery ships, 25 of 25 paint every pixel, 25 of 25 reach the end,
**0 of 25** use a delta) and an independent decoder can. The earlier
`19 of 19` figures above are the BUNDLE's carried assets; 25 is what the
delivery ships. Report:
`docs/2026-09-19-pekerblokken-bindes-til-kjoringen.md`.
**AND THAT ROUND'S OWN SENTENCE WAS TRUE OF THE DELTA AND FALSE OF THE
END-OF-LINE.** It said both escapes state a skip every decoder agrees on.
A delta states a DISTANCE; an end-of-line states only "the rest of THIS
row", so an end-of-line at column 0 closes nothing and claims a row the
stream never wrote -- four of them and an EOB carried an 8x4 frame with
**32 of 32** pixels never decoded, and Pillow refuses those bytes. The class
is wider than that construction and this round SWEPT it instead of patching
it: over every opcode sequence of length 1-4 on a 4x3 frame, **22 620**
streams, this reader carried **703** streams Pillow refuses and drew
**1 492** more differently. PM's recommendation alone (refuse a stream that
painted nothing) leaves **512** and **1 171** -- it would have narrowed the
class a third time. Two clauses ship instead, both `asset_samples_invalid`:
an end-of-line at column 0, and a delta whose horizontal offset would leave
the row (the format puts it inside the line; this reader keeps the cursor
past the row end where a flat decoder rolls it into the next row). After:
**0** carried-here-refused-there and **32** drawn differently. **WHAT IS NOT
CLOSED IS STATED**: all 32 are a run or absolute block that OVERRUNS its
row, which this reader clips at the row end and Pillow spills into the next;
refusing those gives 0 and 0 and costs **15 of the 25** real files, so it is
a limit and not a loss taken. Cost measured on the corpus FIRST: over
**11 441** files scanned across the four raw deliveries and the K2 reference
corpus, the only **25** BMPs on this machine use an end-of-line at column 0
in **0 of 25** and a delta in **0 of 25**, and 25 of 25 still decode to
Pillow's pixels exactly (**3 117 220** compared). R761 rebuilt from a pinned
pre-change tree and from this one is `diff -r`-IDENTICAL, 5 551 files, 50 of
50 viewable, 19 of 19 lossless. `CURSOR_CASES` goes 8 arms to 12 (one for
the cursor rule's ROW clause, PM's `P8`, which survived 51 tests) and the
mutant runner 45 to 47. Report:

- **Account for content: `okf build --accounting PATH` and its judge
`python3 tools/okf_accounting_gate.py` (2026-09-17).**
- The gate was written RED at `0b00de4` and turned GREEN on all six rows by
`accounting.py`. Per README file type it asks how many of the elements a
SOURCE holds are booked as carried / pointer / coded rejection, and both
u (unaccounted) and d (double-booked) must be 0.
- **The fasit is `tools/okf_witness.py`.** It imports no package module
(tested on the live import graph) and is committed as
`tests/fixtures/accounting/*inventory.json`. The package's inventory
implements the SAME definitions a second time: agreement is evidence that
the definitions can be implemented as written, not an independent
measurement of the source.
- **`carried` is checked against the written concept bodies**
(alphanumerics, casefolded), so a gate that drops a line is FOUND.
Measured limit: short elements (labels, one-word titles) are often
present elsewhere in the document. With R761 cut to half, 4 823
paragraphs were reported lost but only 3 titles.
- **Two changes hold without the flag.**
- A build that extracted documents and persisted none exits 1. Door B and
`corpus.measure` are unchanged.
- An image file carried through a persisted document is its own K1b
column, never also `extractor_unknown`. The files come from
`ExtractedDocument.files` (what the resolver actually resolved), never
from byte equality, which would credit R761's 7 unpointed duplicates.
- **R761 WAS refused whole by guard 1.4.0 because of its 71 U+00AD soft
hyphens, and since 2026-09-19 okf removes them itself.** Operator decision
2026-09-18, the chosen alternative verbatim: **one documented
normalisation door BEFORE the guard**, `extract.normalise_extracted`,
removing U+00AD and BOOKING the count as `normalised_soft_hyphen` per
document and per run, in the accounting JSON and in a `**Normalisation**`
bullet in `log.md`. The guard is untouched -- the two alternatives
(weaken the rule, ship a cleaned corpus) were felled as a weaker screen
for every consumer and a fix for one document. `output:zero-width-present`
is an ANY-TIER carrier, so the verdict was formally right at every trust
level and materially a false positive: the 71 are Norwegian hyphenation
points inside words (`ar[SHY]beider`, `bitu[SHY]men`), and the four real
zero-width characters (U+200B, U+200C, U+200D, U+FEFF) plus U+2060 are
**0 of 0** in both deliveries. Those four are NOT removed and U+00A0 NBSP
(6 633 in R761) is not either -- it is not in the guard's set at all.
Applied ONCE, at the end of `extract_document`, so `propose` and Door B
cannot disagree about the text a plan's `text_sha256` indexes; `_pdf_units`
measures its page offsets through the same door, because that table is
CHARACTER offsets rebuilt from the pages while the text it indexes comes
back normalised. Removing a character removes no newline, so every
line-indexed rule downstream is unmoved by construction. **Reach measured
rather than argued: 0 of the 78** readable documents of the K2 reference
corpus carry any of the six characters, 0 in the pinned bundle's concept
bodies, and U+00AD is **0 of the 230** readable tracked files across
`tests/fixtures`, `examples`, `skills`, `docs`, `src`, README and
CHANGELOG -- the door cannot have moved a byte measured here. That last
figure said "0" of ALL SIX until 2026-09-19 and was wrong: **2 of the
230** carry U+200B (`tests/fixtures/accounting/rejected/avvist.html` and
`rejected-inventory.json`), this repo's own known-negative, which the door
is built not to touch.
- **A DOCUMENT REFUSED WHOLE IS NEVER CLEAN, AND A PARTIAL REFUSAL IS NEVER
SILENT (H1, 2026-09-19).** `refused_whole` asked its question only when a
corpus persisted NOTHING, and a refused document's own unit balances by
construction -- every element booked as a coded rejection is u = 0 and
d = 0. Measured by PM: one refused source beside one accepted one gave
`clean = 4 of 4`, `refused_whole = None`, `okf build` exit 0 and three
elements gone unseen, which is the ORDINARY case on a heterogeneous
corpus. `Unit.refused` is a fifth column and the only one that is not a
defect in the report; the build writes `refused` into the accounting and
`R of D document(s) refused whole` into `log.md`. **The exit code does not
move**: it belongs to the whole run, and a corpus holding one unreadable
file among many is ordinary -- so the order's other half, state it in the
accounting, is the one taken.
- **THE JSON ROLE MAP READS THE PUBLISHER'S OWN TAGS (H3, 2026-09-19).**
`count_sts_json` compared the RAW tag string where `count_sts_xml` has
always used `_local`, so N200 Vegbygging:2024's **74 `mml:math`** (2 811
characters) counted as 0; and the publisher's JSON writes a figure's
caption as `figcaption` under the `graphic`, not as the `fig/caption`
NISO-STS writes, so **49 `figcaption`** counted as 0. The `figcaption`
clause is in the JSON map ALONE -- the two maps are written twice on
purpose so row 5 can see a hole in either. NOT ONE OTHER COUNT MOVES,
measured role by role over the eight JSON deliveries on this machine and
the three committed twins: `figure_caption` 0 -> 123/127/62/49/43/27 and
`math` 0 -> 74/3/88, R761 and N601 unchanged, the two existing twins
unchanged. The known-negative for stripping a prefix is N101's **568
`tbx:`** tags, not one of whose local names is a role.
- **The mutation harness is a GATE since 2026-09-19 (H4)**: a surviving
mutant exits 1, where `2 if errors else 0` made `killed 0 of 1` an exit 0.
PM's **X2** -- "a report may declare a document rejected while the bundle
holds it" -- is in the set and killed by a test driven from both sides;
it survived 98 green tests when it was written. The skipped-row guard
measures the DEFAULT sources and not the arguments (H5: row 6 is SKIPPED
exactly when the arguments' corpora are absent, so the branch was
unreachable), and row 6 now SAYS when a corpus measures no element class
at all (H6: on N200 the build proposes 0 plans and exits 2 before the
accounting door, so 16 549 elements land with no declared fate -- a
finding about the run that read as a finding about the build; what it
would take is an STS reader for the JSON delivery, and `standardContent`
occurs 0 times in `src/`).
- **THE PUBLISHED DOOR CONTRACT NAMES WHAT THE GATE READS (2026-09-19).**
The JSON sketch at the top of `okf_accounting_gate.py` is what a consumer
implements `--accounting` from, and it did not name `conversions` -- which
`asset_holds`' conversion route DEPENDS on -- nor `normalised_soft_hyphen`,
`unaccounted` or `double_booked`. A door built from it writes a ledger the
gate reads as "nothing was converted", and every converted image comes out
claimed-and-not-found: **19 of 50** on R761. Two tests hold the sketch
against both sides -- what the gate LOOKS UP (measured with a ledger that
records its own lookups, never by grep) and what the door SERIALISES -- so
"publish everything" is not a fix either.
- **A DOORLESS BUNDLE SAYS WHY (2026-09-19).** Without the flag there is no
ledger, so a converted image cannot be proved carried and is counted
claimed-and-not-found -- honest, and until now silent: the count was
printed and its cause was not. `_tally` names the missing ledger when, and
only when, something was claimed and not found. The gate always passes the
flag, so **no row moves** (RED 2, 3, 6, exit 1, unchanged).
- **Operator 2026-09-17:** the door stays OPT-IN until the reference
corpus's losses are fixed, and of the three proposed exceptions only the
PDF one (heading, paragraph, table) is APPROVED. It moves no number --
no witness counts a heading in a PDF -- so what it changes is that the
gap is a stated limit. An image in xlsx, md, txt, csv, json, odt or rtf
stays unaccounted, and therefore red.
- Reports: `docs/2026-09-17-innholdsregnskapet-rod-gate.md`,
`docs/2026-09-17-innholdsregnskapet-bygget.md`.
- **Judge the RETRIEVAL: `python3 tools/okf_retrieval_gate.py` (2026-09-19).**
A separate question from `okf quality` and a separate command: quality asks
what a bundle looks like, this asks whether the payload for a question
carries the fasit. **Written RED, no capability**: eight rows, exit 0 only
when all are green, 1 otherwise, 2 on wrong input, `--json`. Rows 1-4, 6, 7
run against a synthetic corpus this repo GENERATES and six sets it ships
pinned by sha256 -- no network, no private corpus, no clock; a set whose
bytes moved is exit 2, never a quiet continuation, because **a gold set is
an INPUT and never a constant here** (`okf_consume_measure.py`'s rule, and
this repo is public). **THE CORPUS IS PINNED THE SAME WAY** since
2026-09-19 (`SPECS_SHA256`). Today (measured on the default run
2026-09-21, v1.1 K): **1 (10/10) - 2 (7/7) - 3 (5/5) - 4 (6/6) - 5 (0/1) -
6 (10/10) - 7 (11/14) - 8 (0 of 1 set, NOT RUN without `--real`)**,
`GATE RED: rows 5, 7, 8`.
**THE K2 TEST TRACK IS RETIRED (operator 2026-09-21, v1.1 K)**: material
tied to the operator's employer is not re-measured and not frozen, and
public tests and gates run on invented material. Row 9 (K2) and the `r761`
and `vegnormal` adapters of row 8 are gone (row 8 requires `wiki-20` alone),
and so are the tests that read the K2 bundles, the road-standard builds or
the R761/N101/N200 deliveries; `okf_accounting_gate.py` has no default real
corpus. The synthetic corpus was re-measured for BM25 (`MISS`, `LOOKUP`,
`QUOTA`), so rows 2 and 3 are green through their own fixtures again, and
row 7's mutants patch `bm25` where the default runs there; three survive
(passage body, field title weight, `bm25.RRF_K`) with 0 ranks moved. What
the text below says about rows 8/9, K2 and the three sets is history.
**FOUR OF EIGHT CHEATING ATTACKS WENT THROUGH IT AND ARE CLOSED
(2026-09-19).** PM's checkpoint on `2c8296b` found rows 3, 5, 7 and 8 could
go GREEN without one label becoming true or one concept ranking better, and
an eval written before the capability has exactly that one job beyond being
red today. **Row 8** counted whatever `--real` gave it, so one set of three
read `6 of 6 GREEN` -- and this repo's OWN test asserted `(1, 1, GREEN)` for
a single set; it now requires all three by name and is NOT RUN otherwise,
the measured sets' numbers still printed, and its headline is at QUESTION
granularity because the three sets share no unit. **Rows 2 and 3** took
their denominator from the run, so `k = 32` shrank it to the cases that were
already honest (rows 1, 2, 3 and 6 all green at once); the denominator is
now the PINNED set's, and a forced fixture that stops producing its declared
class is a BROKEN PREMISE counted against its row. **Row 3 also carries a
known-positive**: with the quota off every printed reason is true, which is
not a lie but an empty measurement, so a set may declare
`source_quota_in_force` and the row is NOT RUN when the default cut and the
quota-off cut deliver the same concepts. **The control's own premise was
measured first and was FALSE where it was first put** -- over the five
existing sets the two cuts deliver the SAME concepts (the quota is topped
back up) and 52 labels move `source_quota_exceeded` -> `below_k` with 0
deliveries changing -- so `set-quota.json` is the one set where the quota
genuinely decides. **Row 5** was seven checks the registration made about
itself; three now read GIT (committed and unmodified, its commit is not
itself a ranking change, a ranking change landed AFTER it), the last being
the one that cannot be self-attested. What git cannot prove -- that nobody
read the number first -- is stated, not implied. **Row 7's bar** was 90 % of
a list in the file a capability session edits, so seven duplicate `k = 1`
mutants read `18 of 20 GREEN`; `MUTANT_ROSTER` and `MUTANT_COUNT` are pinned
apart from `MUTANTS`, duplicates are refused, and the bar is the roster's.
**PM's G9 is decided**: `hit = bool(hit_ids) and bool(confirmed)` is
observable and was merely unobserved -- `M14` (a delivery that carries the
citation and is not the concept file's bytes) is the shape that reaches it,
it is FELLED, and no production line changed. The judge's independence is
measured rather than asserted: the index is warmed BEFORE the first
mutation, so patching `delivered_text` moves the payload and not the judge
(index built UNDER the patch: every unit a hit; warmed first: every unit a
miss). Row 9 takes `--k2 SET SHA BUNDLE` and stays RED without one, because
ITS denominator is known -- a deliberate divergence from the order, stated.
Report: `docs/2026-09-19-gjenfinningsgaten-motstand.md`. **ROWS 3 AND 4 WERE THE TWO FINDINGS AND BOTH ARE
CLOSED** (`f81683e`, `05cb190`, 2026-09-20). Row 3: in a bundle built from
ONE source document every concept past the first two carries that document's
`source_file`, so a concept the RANK had already lost came back withheld as
`source_quota_exceeded` -- PM measured the same lie on **13 of 25** real
misses 17.09. A drop now keeps the rule the SAME cut without the quota would
have given it, decided by the code the run itself uses: **2 of 5 -> 5 of
5**. Row 4: no payload key said "this bundle does not answer that", so the
only honest case was `delivered == 0`. `coverage` states the terms the
pre-pass read, the terms no concept in the bundle answers and the terms no
delivered excerpt answers -- facts and no verdict, both candidate verdicts
falsified over 81 questions -- with the gate's own `UNANSWERED_BAR = 2/3`:
**3 of 6 -> 6 of 6**, 0 of 65 real questions marked. **A miss has exactly ONE class** (a fasit not in the bundle, b
below k, c cut by quota/budget, d delivered without the citation, e other),
each FORCED by its own fixture, and an unplaced miss takes the row to 0 of
N. **The judge opens the bundle**: `BundleIndex` reads every concept off
disk before a payload is built, a delivered excerpt whose text is not the
concept file's bytes is not a hit, and the title rules are imported from
`quality` rather than written a second time. **Felled means WORSE, never
merely different** -- removing the quota makes row 3 green, and calling that
a kill would credit the gate with a check it does not have; the two
survivors (document prior dead, `RRF_K` flattened) are reported with what
they measured: **0 ranks and 0 deliveries moved**, and a mechanism for each.
Rows 8 and 9 are never green by leaving something out: the three real sets
are read from path + sha256 (`--real wiki|r761|vegnormal`, one Question per
standard where a question cites two), and K2 is **0 of 6 because the gold
set exists nowhere** while the bundles do. Granularity is stated and the two
forms are NEVER summed: a citation-level set and a concept-level set are two
numbers. Nevnerne re-measured against the sources 2026-09-19 and they hold:
R761 **8** (S1-S6 + KP + KN), vegnormal **32** questions / **43**
`must_cite` / 32 `must_contain`, K2 **6**. The fourth set's own figures are
a consumer's and are not restated here; the gate reads it by path and
sha256 like the others. PM's mixed sum over two sets at two granularities
is carried labelled as recorded, never as the gate's own.
- **Judge a bundle: `okf quality <bundle>` (G37, 2026-09-12).** A per-file-type
verdict, with the denominator on every line, and it is a SEPARATE command
from `okf check` on purpose: `check` is the contract check, and a green one
@ -1481,142 +961,6 @@ R761 **8** (S1-S6 + KP + KN), vegnormal **32** questions / **43**
held by a test. README publishes this bar behind
`<!-- quality-boundary-threshold: ... -->`; SS 7 of the threshold document
carries the seven bundles and the honesty limits.
- **Serve a bundle over MCP: `okf mcp --bundle <dir>` (one bundle) or
`okf mcp --root <dir>` (every bundle under the roots, none known by name).**
Four tools -- `okf_list`, `okf_describe`, `okf_ask`, `okf_fetch` -- each
carrying its REASON in the description a client reads, and every answer
carrying the bundle id and concept id a claim must be attributed to. The
JSON-RPC is written narrowly with stdlib only: an MCP SDK would be this
package's SECOND runtime dependency on the default install path, and
`test_the_only_runtime_dependency_is_the_security_boundary` pins that list
literally; `uv.lock` is untouched. **NOTHING IS CACHED ACROSS CALLS** -- every
call re-walks the roots and recomputes `bundle_ref`, so a bundle added,
removed or rebuilt while the process runs is seen by the next call with no
restart, no config edit and no code change (measured, 9 of 9 discovery checks
over three bundles written while serving). The cost is paid per call and is
published: **0.75 s** for the identity of a 2 756-concept bundle, **5.6 s**
for one ask. Containment is TWO independent checks -- the bundle's own index
must name the concept AND `connectors.safe_resolve` must place it inside the
bundle -- and a mutant removing either one alone still refuses, with a
different code. A concept above `MAX_CONCEPT_BYTES` is refused whole rather
than truncated, and a directory that cannot be read as a bundle is REPORTED
in `okf_list`'s `unreadable` rather than skipped: an absence with no
denominator is not a boundary. The eval is
`tools/okf_mcp_gate.py`, written RED at `5f1772e` before any server existed;
it speaks real stdio to a SUBPROCESS and never imports the server. Today:
**1 (7/7) - 2 (83/181) - 3 (4/4) - 4 (9/9) - 5 (3/3) - 6 (6/6)**,
`GATE RED: rows 2`. **Row 2 decomposes into three numbers and the middle one
is the finding**: 99 of 181 (bundle, anchor) pairs are present in the bundles
at all, 83 of those 99 were reached, and **0 of 83 were met by `okf_fetch` on
the anchor as a concept id** -- the set's anchors and this library's concept
ids are different vocabularies, so every pair met was met through the ranker
and 83 is a FLOOR on the ceiling, never the ceiling. **The architecture choice
between the two shapes is the OPERATOR's**; the rows are its input. Report:
`docs/2026-09-20-mcp-to-varianter.md`.
- **`okf skill --out <dir>` WRITES THE GENERIC SKILL, and that is the default
since v1.1 ordre A (2026-09-21); `--for-bundle` is the opt-in for the
instantiated form.** The candidate below won, on the cost the per-bundle form
actually carries: its numbers go stale the moment its bundle is rebuilt, one
copy per consuming project, and `okf card` derives the same numbers in under
a second so the generic document neither invents them nor states another
bundle's. The instantiated copy still refuses out loud (`bundle_mismatch`)
rather than answering from stale numbers — safe to keep, not enough to keep
default. Both forms now carry `## Working method` and `## Answer form`,
required by `okf check` and by the contract's SS 2.5/2.6.
- **`okf card <folder>` SEES EVERY BUNDLE UNDER A FOLDER (v1.1 F1,
2026-09-21).** Until then only the server (`okf mcp --root`) could; the
generic skill read the one bundle it was pointed at. A path that carries no
`index.md` is a folder (`mcp_server.is_bundle`, discovery's own rule), and the
command prints `mcp_server.overview`: `okf_list` and `okf_describe` with no
bundle named, joined, computing nothing of its own -- one source, two doors,
held by a test comparing the printed bytes against the two functions. A
bundle path prints its card exactly as before. Tests over two invented
bundles: `tests/test_folder_of_bundles.py`.
- **`okf consume <folder>` ASKS EVERY BUNDLE UNDER IT IN ONE CALL (v1.1 F2).**
The reply is `mcp_server.call_ask` with no bundle named (or `--bundle-id` as
its `bundle_id`), serialised by the pre-pass's own `serialise` -- no ranking
of its own, held by a test comparing the bytes. `--question` repeats as
before. Every other flag acts on ONE bundle's cut and the server takes none
of them, so over a folder it is REFUSED by name with exit 2
(`consume.FOLDER_FLAGS` is the allowlist), never dropped; `--bundle-id` on a
bundle path is refused the same way. A bundle path reads exactly as before.
- **`okf check` READS A FOLDER'S REPLY AND THE SKILL TEXT SAYS SO (v1.1 F4).**
`contract_check.check_reply`: a reply carrying `answers` and no `bundle` is
one payload per bundle, each held to all 19 rules on its own; a finding is
named `[bundle_id]`, one every payload carries alike is reported once
unnamed (it is the SKILL's), an answer whose label is not its payload's
bundle is `answer_misattributed`, no answer at all is `payload_invalid`. No
rule was added to `RULES` -- the count stays 19 and a single payload's report
is byte-for-byte as before; a folder's report says `over N payloads`.
Contract SS 2.5.4 names the folder run, SS 8.11 fixes the reply. The
template's step 1 and 4 name the folder (`<FOLDER>`: both generators fill
a lower-case instruction, never a path -- the bundle's parent written
absolute named a checkout, and `test_the_generated_commands_name_this_repository_nowhere` fell on it); the generic header says the server comes first and the skill
is the supplement, and that `--ref` belongs to one bundle.
- **THE SERVER IS THE STANDARD WAY IN AND THE SKILL THE SUPPLEMENT (v1.1 F3,
operator 2026-09-21).** `okf project`'s closing text and README's first
screen say it in that order: register `okf mcp --root` once (every project,
subagents too); the skill beside the bundle is for someone who would rather
register nothing; neither is made again when a bundle is rebuilt. Two tests
hold the ORDER, not just the presence, in both places.
- **`okf card <bundle>` and the generic skill are the one-to-many form.** The card is one bundle's identity, concept count,
conditional-field counts and whole-bundle cost as JSON, **DERIVED on every run
and never written into the bundle** -- storing it would move the bytes of all
six `examples/*/expected-bundle` trees (23 files compared byte-for-byte) and
of the pinned reference bundle, to keep something recomputable in under a
second, and a stored card is one more artefact that can disagree with the
bytes beside it. `okf skill --generic` writes ONE installable consumption
skill for ANY bundle: it carries no bundle's identity and no bundle's numbers,
and the property that makes that checkable rather than asserted is that
`skill.render_generic()` **takes no argument** -- there is no bundle it could
have read. Measured 2026-09-20: two per-bundle skills are identical on **281
of 313** and **311** lines, and the 62 that differ are exactly identity,
concept count, the conditional-field table, the whole-bundle cost and the
breaking point -- the five things that go stale on a rebuild. The update
drill, four artefact classes: MCP one-to-one **0 artefacts / 0 steps**, MCP
one-to-many **0 / 0**, today's per-bundle skill **1 / 1 per consuming
project** (it refuses out loud through `bundle_mismatch`, so its cost is not
silence), generic skill **0 / 0**.
- **THE DEFAULT RANKING IS BM25 SINCE v1.1 ORDER C (C1+C3), 2026-09-21**
(`bm25.py`, `consume.DEFAULT_RANKING`): the best 500-character passage and a
title/path-weighted field, fused by rank; the document prior and the rarity
weight are out of the default. Three rules came over from the fusion because
the suite showed what BM25 alone lost: a directory every id shares is not
read, an identifier (`4.2`) stays one token, and a question word the bundle
lacks is read as the bundle's words it shares a leading WORD with
(`tokens_match`). A concept over `PASSAGE_CHARS` (4 000) is delivered as its
answering passage (`as_passage`, `passage: {start, end, of}`).
`--ranking fusion` keeps everything below reachable; the fusion-mechanism
tests and the reference-bundle pins ask for it by name. The retrieval gate
still measures the DEFAULT, so four of its fusion-built premises are
`xfail(strict=True)` until re-measured. **C4:** `coverage.absent_terms`
(question words held in NO form, after the bridge) and `coverage.weak`
(one such word, or nothing delivered) -- a reading, not a verdict; the
retrieval gate's `marked` reads it beside its own bar. Words that only frame
a question are stopwords in both languages. **C2:** `build_multi_payload`
(`okf consume --question A --question B`, `okf_ask` `questions`) reads the
bundle once (`bm25.prepare`), cuts each sub-question as alone and
interleaves the deliveries round-robin under the same `k`/`limit`; one
question is `build_payload`'s bytes. The search gate's (e)/(f) go through it.
**C3 title inheritance:** a concept titled `Tabell linje N` (the proposer's
mechanical table-block name, `consume.MECHANICAL_TITLE`) is read under the
nearest concept above it in its document (`inherit_table_titles`, ordered by
`source_offset` else `source_lines`), in ranking, excerpt and near misses;
the excerpt carries `own_title`. A reading only -- no bundle bytes move.
**C5 the map:** `bundlemap.build_map` -- one line per source document with
its concept titles in document order, a series (names differing only in
numbers, `SERIES_MIN` = 5) as one line with count and span, at most
`TITLES_PER_LINE` = 24 titles a line, lines capped at `MAP_MAX_BYTES` =
48 000 (`lines_truncated`). The card (`okf card`, `okf_describe`) carries it
as `map` and no longer carries `source_files`. The skill and the server
instructions say: read the map, 2-4 sub-questions in its words, ONE call.
**C6:** the contract's SS 8 example and points 1, 7-10 state the current
form (`okf-consumption/2`'s `withheld` mapping, `absent_terms`/`weak`,
`passage`, `questions`/`subquestions`, `own_title`); `okf check` gains
`passage_malformed` and `subquestions_unindexed` (19 rules). Editing the
contract moved the known-positive to 23 672 / delta 580, and v1.1 F4's
SS 2.5.4 / SS 8.11 edit to **24 620 / delta 592** (`wc -c` 24 028).

The other three stay off.
**`--withheld-titles` IS RETIRED (v1.1 ordre A, 2026-09-21), together with
the flat `withheld` list it existed to name.** Measured on a large real
bundle: the list came to **65.5 % of the written payload**, and not one of
those bytes counted against the budget the same payload reported — so a
reader was handed most of a file the budget line did not know about, to
learn one concept id per withheld concept with nothing beside it. The flag
bought the missing field and was off because buying it for a list that long
cost another 37.9 %. (The corpus is a consumer's; its counts are not
restated here, and the ratio is the argument.)
**`withheld` is now a MAPPING** (`CONTRACT_REVISION` = `okf-consumption/2`,
bumped so a consumer indexing the old key as a list breaks loudly):
`total` (equal to `denominators.withheld`, so SS 5.2's identity closes on the
NUMBERS), `by_rule` (the same total over the closed rule set), `nearest`
(the best-ranked drops BY NAME with title and source document, read off
`ranked` and not off `cut`'s id-sorted output, capped at
`WITHHELD_NEAREST_DEFAULT` = 20) and `complete`. Same question, same bundle,
after: **18.4 % of the old file**. `--withheld-full` brings the
whole list back and is what an instrument classifying EVERY miss asks for —
the retrieval gate and `okf_consume_measure` both pass it and assert
`complete`. `--withheld-nearest N` sets the cap. Three checker rules moved
with the shape, and one is the interesting case: `parent_unfollowable` used
`excerpts` + `withheld` as the bundle's own denominator, which a truncated
block is not, so that clause runs only where the payload SAYS it is complete
— stated in SS 8.6 rather than left as a silence.
The other three stay off. A FIFTH flag is not a ranking widening and is
listed apart: `--withheld-titles`
gives each `withheld` entry the concept's `title`, so a reader can see WHAT
was withheld without reading the bundle (§ 2.2 forbids going to look). The
code is 11 lines; the bytes are the reason it is off. Measured, it grows an
N500 payload 37.9 % and takes the 629-concept K2 bundle's BOOKKEEPING to
122 704 B — past the 120 000-byte limit itself — which would have made the
breaking point then published in the hand-filled K2 copy of
`skills/okf-consume/SKILL.md` ("~75 KB at 629 concepts … at roughly 8 000
concepts") false on the day it shipped. That copy was replaced by a generated
one 2026-09-11; the measurement of the flag stands.

**The standard way in is the server.** Register it once, on user scope,
pointing at the directory that holds your projects. Every project you open can
then ask any bundle under it, subagents included — they inherit MCP tools and
not skills — and a bundle added or rebuilt is seen by the next call. You run
this line; `okf` never starts Claude Code:
```sh
claude mcp add --scope user okf -- okf mcp --root ~/projects
```
**The skill is the supplement**, for when you would rather register nothing:
`okf project` writes it beside the bundle, so starting `claude` in that
directory is enough. It reads every bundle under `./.okf` with the same code the
server runs. Neither has to be made again when a bundle is rebuilt.
Then ask in plain language. Three shapes of request work, and the skill states
the rules for each:

## Known limitations
Read this before pointing the tool at documents you depend on. Every number
here was measured; none of it is a plan.
- **The default gate refuses whole documents, and they are documents you may
want.** Measured 2026-09-20 against a real corpus of official documentation:
`guard-trusted-source`, the shipped default, refused a minority of sources
outright, under `fail_secure` and `quarantine_review`, and most of those were
ordinary reference pages. Not one element of a refused document reaches the
bundle. Rebuilt with `--gate none`, every one of them went through
untouched, so the refusal is the gate and not the readers: a page of
official documentation naturally carries commands and instruction-shaped
text, and the guard reads that as something to hold for review. **The
corpus, its size and the per-page counts are deliberately not published
here** — it belongs to a consumer whose material this repository does not
republish — so this bullet carries no denominator. Run your own: the build
names the count, the files and the codes on every run, which is the number
that actually binds you. The build says so now — it names the count, the files, the codes and
that command — and exits 0, because the bundle is a true record of what the
gate allowed. **If you vouch for the source yourself, build with `--gate
none`;** the bundle then records that nothing was screened. The default was
chosen on one measurement over one pinned bundle's 453 concept bodies, which
is a thin denominator for a decision this consequential.
- **Nothing bounds what one run pays for images.** Each decode link is capped
(`MAX_FILTER_DECODE_BYTES`, 512 MiB) and an oversized picture is refused with
its own code, but the run as a whole has no ceiling: measured, a 70 KB PDF
carrying 16 images each under the declared limit reached **851 MB peak RSS**
and every picture was carried. A hard cap outside Python was measured and is
not available here — `resource.setrlimit(RLIMIT_AS)` raises on Darwin 26.6.2
and is not enforced — so the per-link budget is the whole bound.
`--no-assets` takes the image path out entirely.
- **Three of this repository's own gates are RED, and each red row is a stated
finding rather than a bug to be surprised by.** The retrieval gate is red on
rows 5, 7 and 8, the MCP gate on row 2, and the content accounting's judge
on rows 2, 3 and 6. For a user that means: no ranking change has yet been
registered against a held-out set (row 5), the real-corpus row is NOT RUN
without its private sets and so is red rather than green by omission
(row 8), three mechanical mutants of the BM25 ranking survive with 0 ranks
moved — the passage body, the title field weight and the fusion constant —
so the gate cannot yet tell those parts from their absence (row 7), MCP anchors and concept ids are different
vocabularies so `okf_fetch` cannot be addressed with a set's anchor (row 2),
and the accounting still reports real losses on the reference corpus (rows 2,
3, 6). The rows and their numbers are under [Judge the
retrieval](#judge-the-retrieval-python3-toolsokf_retrieval_gatepy) and
[Serve a bundle over MCP](#serve-a-bundle-over-mcp-okf-mcp).
- **A question worded differently from the bundle finds it through the map.**
The ranking is lexical: a question has to share words with the passages it
should reach. A question in another language, or in a user's words rather
than the documentation's, reaches the right concepts first when it is asked
as two to four sub-questions in the words of the bundle's own map (`okf card`
/ `okf_describe`), which is the working method the skill and the server
state. Asked raw, it may be answered from the wrong concepts, and
`coverage.weak` is a reading, not a guarantee, that this happened.
- **The answer quality of v1.1 was checked on five questions, not measured.**
Five answers, each written by a fresh model context from one call over a
folder of two bundles, graded by hand. What showed red: one answer carried
the right content without the wording the grading required, and the helpers
did not always keep to one call. The question the bundles do not cover was
declined rather than answered. Five questions is a smoke test, not a rate;
the questions, answers and counts are about a consumer's corpus and are not
published here.
- **Speed was not measured for v1.1**, and neither was what a folder reply
costs a client's context limit on a large folder of bundles.
- **The content accounting counts the element classes its vocabulary names, and
no others.** `0 unaccounted` is a statement about those classes, not about the
document: a file whose suffix has no reader is accounted at file level only,
parts no vocabulary names (headers, footers, endnotes, comments, speaker
notes, cell formulas) are outside it, and an image in `xlsx`, `md`, `txt`,
`csv`, `json`, `odt` or `rtf` is unaccounted and therefore red. It is opt-in
(`--accounting PATH`) for that reason. The full list is under
[Build](#build).
- **There is no context graph and no visualisation.** Nothing in this package
draws a bundle.

titles, several sub-questions in one call, a map per bundle, a signal for

over a whole folder of bundles. The payload contract is `okf-consumption/2`,
which breaks a reader of `withheld` as a list. See the CHANGELOG.

defects an independent review found in it closed. A remote `<img src>` or
`xlink:href` is inert text with the address in one code span, never a live

size a carried file has, and — new in this tag — what the stream behind a

text. The pointer block passes the gate like any other body line, and the file
beside it passes nothing. `log.md` says so on every run that carries one.
**Every carried image is one a model can be SHOWN.** A bundle that holds a
picture nothing can read is worse than one that says the picture is missing:
the count reports that it arrived. Measured over the frozen R761 delivery's own
`assets/` (denominator 50): 29 JPEG, 2 PNG and **19 RLE8 BMP** — correct files
that no model decodes. Every asset's type is read off its bytes and tested
against the viewable set; a BMP is converted losslessly to PNG (8-bit
uncompressed, 8-bit RLE8, 24-bit uncompressed), and anything else outside the
set is refused with `asset_not_viewable` and a line in the concept saying what
stood there. A BMP variant this reader does not express — RLE4, BITFIELDS,
16- or 32-bit samples, a 12-byte BITMAPCOREHEADER — is `asset_bmp_unsupported`,
a different fact about the document and a different thing to go and fix.
The reader is stdlib and adds no dependency. Pillow, which this tree already
carries transitively under `pdfplumber`, was measured first and rejected on two
counts: images are carried on the CORE path, where `.html` and `.xml` need no
`[extract]` extra, and an asset's name is its content digest — encoding through
an installed library would make a bundle's identity move with that library's
version, which is the property page rasterisation was felled over. Pillow is
the independent decoder in the tests instead, and against it **19 of 19** of
R761's real RLE8 assets convert with identical RGB, 2 366 365 pixels compared.
A converted asset is ONE asset: one file in `assets/`, one pointer, one row in
the accounting. The pointer's second line — where the source's own file name
and the size in pixels already live — states the original media type, the
original sha256 in full and the new one, so a reader can take the original
delivery, run `shasum -a 256` and find the row.
The cost is measured per image rather than per bundle, with a committed
script (`tools/okf_asset_census.py`) run from two pinned trees over 9 714
image rows: exactly **35 rows moved**. Nineteen are the BMPs, now PNG. The
other **16 are JPEG 2000 objects** carried out of PDF streams — a format no
model decodes either, and one no stdlib route converts, so they are refused
with `asset_not_viewable` and stated in the concept instead of being carried
unreadably. **9 321 of 9 321** JPEG and PNG rows are byte-identical across the
move.
<!-- asset-viewable-media-types: image/gif,image/jpeg,image/png,image/webp -->
**A size CEILING, read off the same corpora (0.10.1).** An image over
`MAX_IMAGE_PIXELS` (40 000 000 pixels) or `MAX_IMAGE_BYTES` (256 MiB) is
refused with `asset_too_large`, counted like every other refusal. The largest
image in the 43-document reference corpus is 4 515 x 4 128 (18.6 MP) and the
largest of R761's 109 pictures is 2 072 x 656 (1.4 MP), so the bound is an
order of magnitude above anything measured.
It exists because a few kilobytes can declare an enormous picture: a 9.6 KB
PDF declaring 3 000 x 3 000 grayscale zeros took 83 MB of peak RSS, a 63 KB
one declaring 8 000 x 8 000 took 276 MB, and the cost is linear in the pixel
count, so one document could take a whole batch build with it — before any
gate, because the guard never sees image bytes.
**Three numbers are bounded, not one, because a claim is not a cost.** What a
container DECLARES (`/Width` x `/Height`, a PNG header, a `data:` payload's
encoded length) is read before anything is decoded. What a carried FILE
measures is read the same way — this package never decodes such a file, so it
pays nothing for it, but writing a 7 000 x 7 000 PNG of 47 705 bytes into a
bundle would hand the consumer the same bomb with `7000x7000 px` printed
beside it. And what a PDF image's STREAM decompresses to is measured before it
is held, a chunk at a time and discarded, because `/Length` is the COMPRESSED
length and a dictionary declaring 1x1 may hang 400 MB of deflated zeros off
it. Measured: that document is 408 516 bytes and cost 892 MB of peak RSS with
only the declared size bounded; with the stream bounded it is refused at
54 MB, and a three-times-larger bomb costs 62 MB rather than 2 436 MB.
**Every link of the filter chain is bounded, not only the first.** A PDF
decodes a stream through a *list* of filters, and `/Filter [/FlateDecode
/FlateDecode]` puts the whole expansion in the second one: measured, 1 636
bytes of file cost 886 554 624 bytes of peak RSS when only the first link was
measured (52 367 360 with every link measured), and the picture was still refused at the end — after the memory had
been spent. An encrypted stream is deciphered first and then measured like any
other.
**And what a link COSTS is bounded, not the size of its output.** Bounding
every `FlateDecode` was still not a bound, because `ASCII85Decode` had been
classed as safe "because it shrinks" and it does not: `z` is that encoding's
shorthand for four zero bytes, so the filter quadruples its input, and
`base64.a85decode` holds about a hundred bytes of memory per byte of input.
Measured in paired subprocesses on an idle machine, the document built once
and read from a file so the fixture is not what is measured: a 33 475-byte PDF
decoding through `[/FlateDecode /ASCII85Decode]` cost 3 261 599 744 bytes of
peak RSS and the picture was CARRIED; bounded it is 42 070 016 and
`asset_too_large`. Doubling the run of `z` takes the old cost to
6 461 558 784 and the bounded one to 40 280 064 — the cost no longer follows
the bomb. So `FlateDecode` is measured a chunk at a time as it is paid, and
every other permitted filter carries a MEASURED worst-case cost per byte of
input which is checked against the budget *before* its decoder is called.
Any other filter — `LZWDecode`, `RunLengthDecode`, `CCITTFaxDecode`,
`/Crypt`, anything written after this — has no measured ratio, so an image
behind one is refused UNREAD with its own code, `asset_pdf_unbounded`, rather
than decoded to find out what it costs. The cap that falls out for
`ASCII85Decode` is read off the corpora the way the pixel bound is: over the
9 668 image objects of the 77 PDFs measured, 16 decode through such a link and
the largest input to one is 450 739 bytes, more than ten times under the cap.
A property test runs **every** chain of length 1–3 over the ten filters
pdfminer decodes — 1 110 of them — and requires each to be delivered under the
bound or refused with a published code, never paid for on the way.
**What the stream bound does NOT reach**, stated because the difference
matters: a stream something else has already decoded, where the memory was
spent before this package was asked. That one is caught by a check on the
decoded length AFTER the decode, which makes it a counted refusal rather than
a bounded one — the picture is dropped by count, not by bound.
**A declared size that is not a size** — a zero or negative `/Width` or
`/Height` — is refused with its own code, `asset_size_invalid`, before the
stream is read. Distinct from `asset_too_large` on purpose: one is a publisher
shipping a picture bigger than this package carries, the other is a dictionary
written wrong or written to be read wrong.
<!-- asset-max-pixels: 40000000 -->
**A remote reference is INERT (0.10.1).** `<img src="https://...">` and an STS
`xlink:href` to an address off this machine are written as text with the
address in one code span, never as `![...](https://...)` and never as a bare
URL a linkifying renderer would autolink. Extraction opens no socket, but a
markdown renderer or an agent that fetches what it renders does, which would
turn "this bundle was opened" into a beacon to whoever wrote the document. The
address is still stated, and so is the figure's caption, because a reader has
to know what stood there.
**`images: N` in a concept counts POINTER BLOCKS, not unique pictures.** One
image referenced twelve times in one concept is `images: 12` and one file in

content.

anything under N pixels", and the distribution offers no N: over the 4 828

`--accounting PATH` accounts for the CONTENT, not only the files. Before
extraction, every source document is inventoried in a per-format element
vocabulary: headings, paragraphs, tables, cells, images, pages, and so on.
After the run, each element gets exactly one fate:
- **carried:** all of its text is in the concepts written for the document,
or its image is in `assets/`;
- **pointer:** a remote image, which is never fetched, or a markdown image
reference kept verbatim;
- **a coded rejection:** the gate's or the reader's code.
The result goes to PATH as JSON and into `log.md`. The build exits 1 when an
element has no fate or has two. A document the gate refuses is logged as
`<file>: <M> elements found in the source, 0 carried: document rejected
`<code>``, and the `Images` bullet then counts what the sources declare.
"Carried" means the text is present, not that it is in the right place. A
short element such as a section label can be found elsewhere in the same
document. The judge is `tools/okf_accounting_gate.py`, which compares the
inventory against an independent witness.
**The account covers the element classes the vocabulary knows, and no others.**
`accounting._READERS` names twelve suffixes, each with its own tuple of classes
(`.md`: heading, paragraph, table, table_row, image, code_block; `.pdf`: image
and page only, which is the approved exception below). Two consequences are
stated here rather than left to be discovered, because "0 unaccounted" reads
like a statement about the document and is a statement about those classes:
- **A file whose suffix has no reader is accounted at FILE level only** —
carried, merged or rejected — never element by element.
- **Parts of a document that no vocabulary names are not counted, so content
there can go missing under exit 0 and `0 unaccounted`.** Verified against the
readers: `.docx` reads `word/document.xml` and `word/footnotes.xml`, so
headers, footers, endnotes and comments are outside; `.pptx` reads
`ppt/slides/slideN.xml`, so speaker notes, masters and layouts are outside;
`.xlsx` reads the worksheets, the shared strings and the drawings, so cell
comments are outside and a cell contributes its cached value or inline
string, never its formula; `.rtf` skips the `header`, `footer`, `info`,
`pict`, `stylesheet`, `fonttbl` and `colortbl` groups. A hidden slide or
sheet IS counted — it lives in the same part as a visible one. Nothing here
is built for now: the list is what the account does not claim.
**Two operator decisions, 2026-09-17.** The accounting stays OPT-IN until the
losses it reports on the reference corpus are fixed, because a default-on door
would fail builds that pass today. And of the three exceptions the gate
proposed, only the PDF one is approved: a PDF without a structure tree
declares no heading, paragraph or table, so no witness can count them. An
image in a workbook, or in md, txt, csv, json, odt or rtf, stays unaccounted
and therefore stays red.
A run that refused a document whole says so in both places: the accounting
carries `refused` and each document's own `status`, and `log.md` carries
`R of D document(s) refused whole`. The exit code does not move for it — it
belongs to the whole run, and a corpus holding one unreadable file among many
is ordinary — so the count is what keeps a partial refusal from being silent.
The judge treats such a document as never clean, with its elements in their own
`refused` column: every one of them is booked honestly as a coded rejection, so
u and d both stay 0 and nothing else could see the loss.
**The soft hyphen is removed before the persist gate, and counted** (operator
decision 2026-09-18). U+00AD is in `llm-ingestion-guard`'s zero-width set, and
`output:zero-width-present` is an any-tier carrier: a document carrying one is
`fail_secure` at every trust level. Measured on R761 Prosesskoden:2025 — 71
U+00AD, and 0 of U+200B, U+200C, U+200D, U+FEFF and U+2060 — those 71 are
Norwegian hyphenation points inside words (`ar[SHY]beider`, `bitu[SHY]men`),
so a 701-page process code was unreadable for the whole chain over typography.
`extract.normalise_extracted` removes that one character from every extracted
text and reports the count as `normalised_soft_hyphen`, per document and for
the run, in the accounting JSON and in a `**Normalisation**` bullet in
`log.md`. The guard is not touched and the other four characters are not
touched: they carry no typographic job in running text, so removing one would
be a decision about what the guard screens for, taken in the wrong repository.
U+00A0 NBSP is not in the guard's set and is not touched either. Reach,
measured 2026-09-19: **0 of the 78** readable documents of the reference
corpus carry any of the six characters, so no bundle measured here moves.
Two things hold with or without the flag:
- `okf build` exits 1 when it extracted at least one document and persisted
none.
- An image file beside a document is counted once. If a persisted document
carried it, it is in the conservation identity's own column

otherwise it is a coded rejection.

**The ranking is BM25 since v1.1** (`--ranking bm25`, the default). Two signals
are fused by rank: each concept's best 500-character passage, and its title and
id path weighted above its body. A word the bundle does not hold weighs nothing
by itself; one it holds in another form — a Norwegian inflection or compound —
is read as that form. A concept longer than 4 000 characters is delivered as
the passage that answers, under the nearest heading above it, marked with
`passage: {start, end, of}`, so the whole can be fetched by its `concept_id`.
`--ranking fusion` is the older three-signal ranking; the flags below that say
they widen a signal (`--cost-vocabulary`, `--rarity-weight`) belong to it and
are refused without it. The rest of this section describes the fusion.
**A table fragment is read under the heading it stands under.** When the
builder can only name a table block by the line it starts on (`Tabell linje
N`), `okf consume` reads it under the title of the nearest concept above it in
the same document — in what it ranks and in what the excerpt shows — and the
excerpt keeps the file's own title as `own_title`. No bundle byte moves.
**The payload says when the bundle looks like it does not cover a question.**
`coverage.absent_terms` lists the question's words the bundle holds in no form
— not as written and not through a relative it uses — and `coverage.weak` is
true when one such word exists or nothing was delivered. It is a reading with
its rule in the open, not a verdict: the reader rephrases in the bundle's own
words, and if it stays weak, says the bundle does not cover the question. Words
that only frame a question (`how often`, `hva står i`) are not topic words.
**Several sub-questions in one call.** A broad question is asked best as two
to four narrow ones in the bundle's own words: `okf consume ./bundle --question
"first" --question "second"`, or `okf_ask` with `questions`. The bundle is read
once, each sub-question is ranked and cut as it would be alone, and the
deliveries are interleaved — first excerpt of each in turn, then the second,
duplicates dropped — under the same `--k` and `--limit` one question gets. The
payload then carries `questions` instead of `question`, every excerpt names the
`subquestions` it answered, and `coverage` has one block per sub-question, with
`weak` true only when every sub-question is weak. One question gives exactly
the payload it always did.
The consumption contract (`docs/consumption-contract.md` § 8.8–8.10) states

`passage_malformed` refuses a `passage` that is not whole numbers with
`0 <= start < end <= of`, and `subquestions_unindexed` refuses an excerpt whose
`subquestions` are not distinct indices into the payload's `questions`.

`by_rule`, the best-ranked drops by name — with title and source document, so a
reader who sees a near miss can ask for it — and `complete`, which says whether
those names ARE the whole set. `--withheld-nearest N` sets how many are named
(default 20) and `--withheld-full` names every one, which is what an instrument
classifying every miss should ask for. The default moved on a measurement: on a
large real bundle the flat list came to **65.5 % of the written payload**, none
of it counted against the budget the same payload reported, and none of it
anything a reader could act on. The same question after the change costs
**18.4 %** of what it did before. `--withheld-titles` is retired by
that change — it existed to buy the one field the near misses now carry.

## Judge the retrieval: `python3 tools/okf_retrieval_gate.py`
A separate question from `okf quality`, and a separate command: quality asks
what a bundle looks like, this asks whether the payload for a question carries
the fasit — and whether the payload says so when it does not know.
```bash
python3 tools/okf_retrieval_gate.py # eight rows, one exit code
python3 tools/okf_retrieval_gate.py --json # the same rows as JSON
```
Eight rows, exit 0 only when every one is green, 1 otherwise, 2 for wrong
input. Rows 1–4, 6 and 7 run against a synthetic corpus this repository
generates and six question sets it ships, pinned by sha256: no network, no
private corpus, no clock. A question set is always an input — `sha256` is
checked before a byte is measured and a mismatch is exit 2 — because a gold
set names a consumer's documents and this repository is public. **The corpus
is pinned the same way** (`SPECS_SHA256`): every row counts against those
documents, so moving them without moving the pin is exit 2.
**It is RED today, on rows 5, 7 and 8**, and each of those is a
finding rather than a defect in the gate:
| row | what it asks | today |
|---|---|---|
| 1 | hit@payload, one fasit entry = one unit | 10 of 10 |
| 2 | every miss carries exactly one class, each forced by its own fixture | 7 of 7 |
| 3 | the `rule` the payload prints for a withheld fasit is the true one | 5 of 5 |
| 4 | an uncovered question comes back marked, a covered one does not | 6 of 6 |
| 5 | a hold-out set, frozen and with its threshold written first | 0 of 1 |
| 6 | every delivery confirmed against the bundle's own bytes | 10 of 10 |
| 7 | mechanical mutants of the ranking and the cut, felled | 11 of 14 |
| 8 | the real set, from path + sha256 | 0 of 1 set, NOT RUN without `--real` |
**The public rows run on invented material only** (operator decision
2026-09-21). The test track built on material tied to the operator's employer
is retired rather than re-measured or frozen: its row 9 is gone, row 8 no
longer reads the two sets built on it, and no test or gate here needs that
material to run.
Rows 3 and 4 were this gate's two findings and both are closed, which is what
a gate written before the capability is for. Row 3: in a bundle built from ONE
source document, every concept past the first two carries that document's
`source_file`, so a concept the RANK had already lost came back withheld as
`source_quota_exceeded`. A drop now keeps the rule the same cut without the
quota would have given it, and only a candidate that cut would have delivered
is named as the quota's — 2 of 5 to 5 of 5. Row 4: the payload had no key a
consumer could read as "this bundle does not answer that", so an uncovered
question came back with excerpts and no statement. `coverage` states the terms
the pre-pass read, the terms no concept in the bundle answers and the terms no
delivered excerpt answers — facts, no verdict, and the one bar is the gate's
own `UNANSWERED_BAR = 2/3` — 3 of 6 to 6 of 6.
Row 7's mutants patch the code the DEFAULT ranking runs (BM25 since v1.1),
and it reports three survivors with what they moved rather than with a shrug:
the passage signal reading no body, the field signal weighing no title and no
path, and a flattened fusion (`bm25.RRF_K`) each moved **0 ranks and 0
deliveries** on these fixtures. Each has a mechanism: the field signal still
reads every body, every synthetic body opens with its own title as a heading,
and over two signals `K` only reorders a concept whose two ranks lie far apart,
which no fixture holds.
Row 8 is never green by leaving something out: it requires every named set and
is NOT RUN until it has them — one set of three used to read `6 of 6 GREEN`.
The set lives in another repository and is read, never written:
`--real wiki <set.json> <sha256> <bundle>` runs it.
Granularity is stated on every line and the two forms are never summed: a set
naming a citation is measured at citation granularity, a set naming only a
section is measured at concept granularity. **Row 8's own headline is
therefore at QUESTION granularity**, with the two unit totals printed below
it, each with its own denominator.

## Serve a bundle over MCP: `okf mcp`
Two shapes, one implementation, and the difference is what an agent has to be
told in advance.
```sh
okf mcp --bundle .okf/my-bundle # one server, one bundle
okf mcp --root ~/bundles --root ./.okf # one server, every bundle under the roots
```
`--bundle` serves exactly one bundle, fixed at startup; its tools take no
bundle argument, because there is nothing to choose. `--root` (repeatable)
serves every bundle found under the given directories and **knows none of them
by name**: it discovers them per call, so a bundle you add, remove or rebuild
while the server is running is picked up by the next call. No restart, no
configuration edit, no code change.
Four tools on a multi-bundle server and **three** on a single-bundle one —
`okf_list` is absent where there is nothing to list — and each one's description
says why it exists:
| tool | what it answers |
|---|---|
| `okf_list` | which bundles are reachable right now, with each one's content identity and concept count (multi-bundle servers only) |
| `okf_describe` | what one bundle is: id, ref, concept count, how many concepts carry each conditionally-written field, and its `map` — one line per source document with its section titles, a series of like-named documents as one line. Omitting `bundle_id` on a multi-bundle server describes them all, as `okf_ask` does |
| `okf_ask` | one question, or two to four sub-questions in `questions`, and one bounded payload of excerpts, each with its bundle id, concept id, title and provenance locators. Omitting `bundle_id` on a multi-bundle server asks them all and splits the budget |
| `okf_fetch` | one named concept, verbatim, with its frontmatter and locators |
**The server carries the working method, because a subagent inherits MCP tools
and not skills.** Its `instructions` and the `okf_ask` description state the
short form — read the map, write two to four sub-questions in the bundle's own
words and send them in ONE call, read what lay just outside the cut and ask
again with its words, then write one answer in the questioner's language. Claude Code
truncates both at 2 KB, so the long form stays in the skill, which has no such
cap; a test holds the short one under the limit with a control, because a
truncated method is worse than a missing one.
**Nothing is cached between calls, and that is the design.** Every call
re-reads the directories and recomputes the bundle's content identity, so the
identity in an answer is a fact about the bytes at the moment of the call
rather than at startup — a server that answered from yesterday's bundle is the
one failure you cannot see from the outside. The cost is real and is paid per
call: on a 2 756-concept bundle the identity is a 0.75 s hash of the whole
concept tree, and one `okf_ask` is 5.6 s.
**Refusals are loud.** A path climbing out of the bundle, a symlink leaving the
served root, a bundle id nobody answers to, a directory whose manifest cannot be
read, and a concept above the server's size ceiling each come back as an error
with a code — never as a plausible-looking empty answer. A concept over the
ceiling is refused whole rather than truncated: a truncated concept read as
whole is a wrong answer that looks right. A directory that cannot be read as a
bundle is **reported** in `okf_list`'s `unreadable`, not skipped.
The protocol is written with the standard library only. An MCP SDK would be
this package's second runtime dependency on the default install path, for four
JSON-RPC methods and a newline framing — see
[Requirements](#requirements).
`tools/okf_mcp_gate.py` is the eval: it starts the server as a subprocess,
speaks real stdio to it, and measures six rows. It was written red before the
server existed, and it is red today on row 2. The measurements, the update
drill and the limits are in
[`docs/2026-09-20-mcp-to-varianter.md`](docs/2026-09-20-mcp-to-varianter.md).
### One skill for every bundle: `okf skill` and `okf card`
**`okf skill --out <dir>` writes one installable skill for ANY bundle. That is
the default since 2026-09-20**, and `okf project` installs the same one:
```sh
okf skill --out ~/.claude/skills/okf-consume-any
okf card .okf/my-bundle # the per-bundle numbers, as JSON, on demand
```
The generic skill carries no bundle's id, no ref and no count; it tells its
reader to run `okf card <bundle>` first. The card is **derived on every run and
never written into the bundle**, so there is no second artefact that can
disagree with the bytes beside it. It is therefore never stale, and one skill
serves every bundle a project holds.
**The card carries the bundle's map** (`map`): one line per source document —
its name, then the titles of its concepts in document order — and documents
whose names differ only in their numbers (a changelog per release) as one line
with the count and the span. It is the bundle's own words, to write
sub-questions in. The lines are capped at 48 000 bytes together
(`lines_truncated` counts what a larger bundle leaves out), and a line lists at
most 24 titles. The map replaced the card's flat `source_files` list.
**Point it at a folder and it sees every bundle under it** (since v1.1 F):
```sh
okf card ~/okf # every bundle under the folder, each with its card
```
It prints what the server's `okf_list` and `okf_describe` give with no bundle
named -- the listing (id, ref, concept count, directory), the directories that
look like a bundle and cannot be read as one, and every bundle's card -- and it
computes nothing of its own: the command calls the server's two functions. A
bundle added or rebuilt under the folder is in the next run's answer with
nothing regenerated. Pointed at one bundle, it prints that bundle's card as
before; the command decides which it was given by the same rule discovery uses
(a directory carrying an `index.md` is a bundle).
**And one question -- or several sub-questions -- asks every bundle under the
folder in one call:**
```sh
okf consume ~/okf --question "first sub-question" --question "second sub-question"
okf consume ~/okf --question "..." --bundle-id my-bundle # just one of them
```
The reply is the server's `okf_ask` with no bundle named, byte for byte: the
budget split between the bundles, one payload per bundle, and every excerpt
carrying the id of the bundle it came from. There is no ranking of its own.
The flags that change how ONE bundle is cut (`--ref`, `--ranking`,
`--no-source-quota` and the rest) are refused over a folder, by name, rather
than dropped, because the server takes none of them; point at one bundle to use
them.
`okf check --payload` takes that reply as well as a single payload: every
bundle's payload is held to every rule on its own, a finding is named with its
bundle, and an answer labelled with a bundle its payload does not describe is a
finding (`answer_misattributed`). The generic skill tells its reader both
forms, and says to use the server's tools first where they are registered.
`okf skill <bundle> --for-bundle` still writes the per-bundle form, with the
identity and the numbers measured into the text — which is exactly what makes
that file stale the moment the bundle is rebuilt. It refuses out loud when it
was not regenerated (`bundle_mismatch`), so its cost is a stopped session
rather than a wrong answer; that is why it is no longer the default.
Measured on two unrelated bundles: two per-bundle skills are identical on 281
of 313 and 311 lines. The 62 lines that differ are exactly identity, concept
count, the conditional-field table, the whole-bundle cost and the payload-cost
section — the five things a rebuild invalidates.

# Two findings in the image path, closed before push (0.10.1)
From an independent review of `v0.10.0` (an internal measurement note, not
committed here). The review's verdict was "safe to push, with reservations": no blocker, and
byte-identity, determinism and `--no-assets` parity all hold. Both findings
land with the shipped defaults (`--assets` on, `--gate guard-trusted-source`),
and both are new in 0.10.0, because before it no reader read an `<img>`
attribute or opened an image stream.
Both repros were rebuilt here as tests before anything was fixed
(`tests/test_asset_limits.py`, 17 tests).
## MAJOR-1: a remote reference was a live markdown image link
Reproduced:
render_missing('https://collect.example.net/p.gif?u=S', href=…)
-> '![fig](https://collect.example.net/p.gif?u=S)\nImage: … (not carried: …)'
The first line is a live image link to an address the document's author
controls, query string included. This package opens no socket. A consumer that
renders the bundle, or an agent that fetches what it renders, does — which
turns "this bundle was opened" into a beacon (and a server-side consumer into
an SSRF). Measured with guard 1.4.0: `PRESET_USER_UPLOAD` fails the document
secure, `PRESET_TRUSTED_SOURCE` — the build's default — persists it.
**Fixed in `render_missing`:** a reference with an `href` is written as
`Image: <name> (not carried: <reason>) address: `<address>`` — inert text,
with the address still stated, because a reader has to know what stood there.
**Pinned as a property, not a string.** `FOREIGN_IMAGE_LINK` matches any
markdown image whose target is not this bundle's own `assets/`. It is asserted
over the two readers that resolve references (HTML, STS), over three shapes of
remote address (`https:`, `//host`, upper-case scheme), and over a whole built
bundle of the shipped fixture inbox. The known-positive beside it: a local
image still produces a pointer block that `IMAGE_POINTER` matches, and a
`data:` URI image is still carried.
The tier asymmetry is the guard's own question and was sent to
`llm-ingestion-pipeline-security` with the repro
(`20260917T221801Z-428505178`). Nothing was built there.
## MAJOR-2: nothing bounded a declared image size
Reproduced with the review's own generator, rebuilt in the test file: a PDF
declaring one grayscale image of compressed zeros.
| declared | PDF file | peak RSS |
|---|---:|---:|
| 3 000 x 3 000 | 9.6 KB | 83 MB |
| 8 000 x 8 000 | 63 KB | 276 MB (review's measurement) |
The cost is linear in the pixel count, so 50 000 x 50 000 is several GB. One
document — malicious, defective, or a legitimately enormous scan — could take
a whole batch build with it, before any gate, because the guard never sees
image bytes.
**The bound is read off the corpora, not chosen.** Over the 4 828 image
objects of the 43-document reference corpus the largest is 4 515 x 4 128
(18.6 MP, a landscape drawing). Over R761's 109 delivered pictures the largest
is 2 072 x 656 (1.4 MP).
- `MAX_IMAGE_PIXELS = 40 000 000` (2.1x the largest measured).
- `MAX_IMAGE_BYTES = 256 MiB` of samples.
- Over either: `asset_too_large`, counted like every other refusal, with the
declared size in the reason. Never a silent skip and never a killed build.
**Checked on what the container DECLARES, before anything is decompressed.**
`stream.get_data()` is what pays for the bomb, so the declared `Width` and
`Height` are read first. The order is observable, not asserted: the test feeds
a PDF whose image stream is corrupt AND whose declared size is over the bound.
Decoding first gives `asset_pdf_unsupported`; reading the size first gives
`asset_too_large`. `encode_png` refuses the same size on its own, so the
encoder does not trust its caller.
> **CORRECTION, 2026-09-18 — this paragraph claimed a defence this round did

**The `data:` URI, which the review flagged and did not measure,** is closed by
the same bound, checked on the payload length before decoding (base64 expands
by 3/4). Measured: refused with `asset_too_large` as a row.
Not bounded, and stated rather than hidden: an image FILE carried verbatim is
never decoded, so its cost is its own file size. (Corrected 2026-09-18: it is
bounded now. This package pays nothing for such a file, but a 7 000 x 7 000
PNG of 47 705 bytes written into a bundle hands the consumer the same bomb
with `7000x7000 px` printed beside it, and the README's own first sentence
about this bound said it was refused.)
## The determinism defect PM added to this order
pdfminer names an inline image (`BI … EI`) from `id()` of a Python object.
Measured 2026-09-17: two concept files of the reference corpus differed
between two builds of one commit, in the pointer line
(`Image: page-3-6344095824` against `page-3-4555034320`). That breaks the
bit-exact rebuild invariant.
**Fixed:** a name pdfminer derived from `id()` — all digits, no resource name —
is replaced by the image's position on the page (`page-3-inline-2`). The test
builds a PDF with an inline image and compares two extractions with the
`_pdf_pages` cache cleared between them.
## The three MINOR findings
- **`images: N` counts pointer blocks, not unique pictures** (12 pointers to
2 files is `images: 12`). Documented in the README rather than changed:
the number is the count of places a picture stands, dedup is on content, and
changing it would move bundle bytes and lose the placement count.
- **A concept that is only a pointer block is persisted as substantive.**
Documented: "degenerate" means zero characters after stripping whitespace,
and a pointer block is text. Changing the definition is a spec question.
- **`data:` URI:** closed, see above.
## Verification
- `tests/test_asset_limits.py`: 17 tests, both repros red first.
- Full suite 2 045 passed, 1 skipped; `ruff`, `ruff format --check` and
`mypy --strict` clean. Re-run after `git add` against a clean tree.
- **R761 unchanged (PM's measurement, repeated):** `--gate none` gives
`50 carried of 50 found`, 50 files in `assets/`, and `diff -rq` against the
bundle built before this change reports no difference.
- `tools/okf_accounting_gate.py`: green on all six rows.
## Proposal
Version `0.10.1`. No tag, no release, no push — the content accounting sits in
the same tree and PM wants the order of the two settled first.

# Content accounting in `okf build`: built
Capability loop, step 5. This work carries out order
`20260917T134442Z-3174112963`. The judge is `tools/okf_accounting_gate.py`,
written red at `0b00de4`. Its checks are unchanged here.
## Result
The gate is GREEN on all six rows (exit 0):
- rows 1 to 5 on the fixtures;
- row 6 on R761 Prosesskoden:2025, 110 of 110 units under both builds.
None of the three proposed exceptions was needed for these corpora. They are
still not approved, and the build does not apply them. A workbook carrying an
image, which the reader does not carry, is reported as one unaccounted element
and exits 1. `tests/test_content_accounting.py` holds that.
## What changed
1. **`okf build --accounting PATH`** (`src/llm_ingestion_okf/accounting.py`).
- **Before extraction:** an inventory of every source document in the
gate's per-format vocabulary.
- **After the run:** one fate per element — `carried`, `pointer` or a coded
rejection — written as JSON to PATH and summarised in `log.md`.
- **Exit:** 1 when anything is unaccounted or double-booked.
2. **`carried` is checked, not declared.** Every piece of an element's text
must be present in the concept bodies written for that document. Both sides
are compared as letters and digits only, case-folded. A container is
carried when its contents are.
- **Images** are booked from what the reader did with each placement:
carried, `asset_remote` (booked as `pointer`), or the reader's rejection
code.
- **A refused document** books every element under the gate's code.
3. **One fate per file.**
- An image file that a persisted document carried is no longer also an
`extractor_unknown` rejection. It has its own column in the conservation
identity.
- The set of carried files comes from what the resolver actually resolved
and carried (`ExtractedDocument.files`), never from byte equality.
- Why not byte equality: the gate's own first run on R761 credited 7
unpointed files that share bytes with pointed ones (d = 57, not 50).
4. **Exit 1 when documents were extracted and none persisted.** This is the
decision recorded in `docs/2026-09-17-innholdsregnskapet-rod-gate.md`.
- Door B's library function and `corpus.measure` are unchanged.
- One test in this repository relied on exit 0 here:
`tests/test_cli_gate.py::test_build_refuses_a_document_the_real_guard_refuses`.
- No script relies on it.
- `okf project` calls the build as a function, so it does not see the new
exit code. A project over a folder where every document was refused
still writes a skill. This is noted, not changed.
5. **`log.md`.**
- With `--accounting`, the `Images` bullet counts what the sources declare,
and each refused document gets its own line.
- The K1b line names the carried column only when that column is
non-zero. The pre-change line is therefore byte-identical for a corpus
without such files, which is tested.
## The check can fail, and where it is weak
- **Known-positive.** A gate that silently drops one line of `notat.md`
leaves K1b intact. It is reported as `paragraph 1 unaccounted`, and the
build exits 1 (test).
- **Control on R761, measured.** The document was built with `--gate none`,
as one concept, and then its written text was cut.
| Written text | Result |
|---|---|
| whole | 0 unaccounted over 31 096 elements |
| cut to half | 4 823 paragraphs, 3 621 sections and 55 list items unaccounted — but only 3 titles and 16 section labels |
| first 200 characters only | 12 475 of 12 528 paragraphs and 2 761 of 2 761 titles unaccounted, but 150 of 197 cells |
- **The limit.** The check proves that a string is present, not where it is.
A short element (a label such as `84.1`, a one-word title, a one-number
cell) is often present elsewhere in the same document, so its loss can go
unseen. Long elements are well covered.
- **Why not stricter ordered matching.** It would close part of this, but the
inventory's order is not always the written order: the pptx inventory lists
a slide's tables before its shapes. It is not built.
## Independence, stated precisely
`tools/okf_witness.py` imports nothing from this package; a test proves that on
the live import graph. The package's inventory implements the SAME
definitions a second time, and for markdown it reuses the proposer's own fence
rule (`propose.fenced_lines`), where the witness has its own. Agreement on the
fixtures (row 2, 13 of 13) is evidence that the definitions can be implemented
as written. It is not an independent count of the source. The independent
count is the witness's, and it is committed as data.
Known divergence, not exercised by any fixture: two fenced blocks with no
line between them are one `code_block` here and two in the witness.
## Cost
Measured on the 43-document reference corpus (`K2/trinn1`), built twice
from one snapshot of `src/`, each time as one run under `/usr/bin/time -l`:
| | wall | peak RSS | result |
|---|---:|---:|---|
| without `--accounting` | 3 902 s | 8.83 GB | exit 0 |
| with `--accounting` | 4 646 s | 9.36 GB | exit 1, 28 unaccounted |
- **The difference is +744 s (+19 %) and +0.53 GB.** The run without the flag
shared the machine with the test suite and two gate runs, so its wall time
is inflated and the true difference is likely larger. The 0.10.0 figure for
the same build was 3 088 s.
- **Most of the cost is the PDF inventory**, which opens every PDF a second
time with pdfplumber to list image placements.
- **Every concept file is the same in both builds except two,** and the
reason is not the flag. It is a 0.10.0 determinism defect (see Findings).
`log.md` differs by the accounting lines, as it should.
**Why the door is not the default.** It is opt-in for two reasons:
1. It costs about a fifth of the build time.
2. On the reference corpus, the check FAILS. A default-on flag would turn
every existing `okf build` of that corpus into exit 1 until the defects
below are fixed, or an exception is approved.
That second point is the door working as intended, and it is also a breaking
change nobody has decided on.
## Findings on the reference corpus
The door reported 28 unaccounted elements. Four of them were false positives
in the check itself, and both mechanisms are now fixed, each with a test:
- **A converter attribute between carried words:** `[Sted]{.mark}` for a
highlighted placeholder (1 element).
- **A `w:br` inside a table cell,** which the converter writes on two
grid-table rows (3 elements: the paragraph, its cell
and its table).
Recomputed on the same bundle after those fixes, **24 remain, and all 24 are
real losses:**
1. **22 images on PDF pages that have no text layer.**
- Affected: `Bilag 9.1` (16), `RIG-R02` (4), `Bilag 9.2` (2).
- Cause: `_pdf_pages` drops a page with no text, and its images with it.
They are neither carried nor rejected.
- pdfplumber lists 212 / 102 / 6 placements where the reader handled
196 / 98 / 4. The difference equals the placements on text-less pages,
exactly, in all three documents.
- These are plausibly the most important pictures in those files, because
a page with no text is a drawing or a scan.
2. **2 docx headings in the `Tittel` (Title) style.**
- Affected: Vedlegg 2 and Vedlegg 3.
- Cause: the converter moves a Title paragraph into document metadata, so
the body has an empty `# ` where the title stood.
Neither is fixed here. Both change bundle bytes, so each is a separate order.
The 24 combine two measurements: 22 image losses from the door build, and 2
text losses from recomputing the text accounting over that same bundle with
the fixed check. A fresh door build after the fixes was not run.
**A determinism defect in 0.10.0, found by the same comparison.**
- Inline PDF images (`BI … EI`) get their name from pdfminer, which derives
it from `id()` of a Python object. The pointer line
`Image: page-3-6344095824 (not carried: …)` therefore changes between runs.
- Affected: two concept files of `K2/trinn1` (`bilag-6-teknisk-oppsett`,
`bilag-9-1-...`).
- This breaks the bit-exact rebuild invariant. It is not caused by this work.
It is reported here and not fixed, for the same reason as above.
## Proposals, not carried out
- **Version:** `0.11.0`. The change adds a flag and changes an exit code for
existing users. The PM wants an independent review before any tag.
- **Not a default:** see Cost.
- **Separate orders:** carry the images of text-less PDF pages; keep a docx
Title paragraph in the body; make inline PDF image names deterministic.
- **A cheaper PDF inventory:** count image placements from the pages the reader
already parsed, and keep an independent count only in the gate.

# Content accounting in `okf build`: the gate, written red
Capability loop, step 3. This session adds no capability. It adds the gate a
later capability has to turn green, together with the fasit that gate judges
against.
- Command: `python3 tools/okf_accounting_gate.py [--json] [--r761 DIR] [--consume]`
- Exit codes: 0 when every failing row (1–6) is green, 1 otherwise, 2 when
the gate did not run.
- Fasit: `tools/okf_witness.py`, committed as
`tests/fixtures/accounting/*inventory.json`.
- Tests: `tests/test_accounting_gate.py`, 42 tests, green.
## Why a gate at all
`okf build`'s conservation identity, `merged + coded rejections == N`, counts
FILES. Two things happen that the identity cannot see, and both were
reproduced here on `bc39e80` (v0.10.0) before any code was written:
- **A file can be merged while content inside it is gone.** No inventory of
the source exists, so nothing can state what a merged file lost.
- **A file can be carried and rejected at once (finding B).** The fixture
corpus has a `graphics/` directory next to its documents. Its two PNGs are
carried into `assets/` through the documents that point at them, and the
same two files are also counted as `extractor_unknown` rejections. Each has
two fates.
- **A rejected document is logged as if it held nothing (finding C).** The
fixture document the guard refuses produces
`Images: 0 carried of 0 found`, although its source declares one image.
## The fasit is independent
The witness imports no `llm_ingestion_okf` module. A test runs every witness
in a fresh process and then reads `sys.modules`. A control run of the same
check, with the package pre-loaded, shows the check fires.
The witness counts each format by the format's own rules:
- STS: ElementTree, and the publisher's JSON node tree.
- docx, pptx, xlsx and odt: the zip members' own XML.
- PDF: pdfplumber objects, and poppler (`pdfinfo`, `pdfimages -list`).
- HTML: `html.parser`.
- md, txt, csv, json and rtf: stdlib readers, and a control-word scan for rtf.
Four documents are also pinned to hand counts.
**Two witnesses disagreed by tag, and both disagreements were about placement
rather than content** (R761, measured). A section's label is `sec/label` on
7 714 sections in the XML. The JSON puts it at `sec/label` on 4 954 of them
and at `sec/title/label` on the other 2 760. A table's label is
`table-wrap/label` in the XML (10) and `table-wrap/table/caption` in the JSON
(10). The witness therefore counts ROLES, and the mapping is written in
`okf_witness._sts_role` together with these numbers. After the mapping, the
two R761 witnesses agree on all ten roles.
The PM's figures were re-measured and all hold: `p` 12 528, `title` 2 761,
`td` 197, `list-item` 111, `graphic` 50, 109 other files in the zip (50
pointed at, 59 not). The PDF witnesses agree at 701 pages and 50 images;
pdfplumber takes 50 s for that and poppler 1 s.
## The door the capability must open
The gate reads `okf build --accounting PATH`: one JSON object with a
per-document `inventory` taken before extraction and before the gate,
per-element `fates` (`carried` / `pointer` / `rejected{code}`), and exactly
one `fate` per inbox file that is not a document. It also reads one line in
`log.md` per rejected document:
<source_file>: <M> elements found in the source, 0 carried: document rejected `<code>`
The full contract is in the module docstring. Until the flag exists, row 2 is
0 of 13, and row 3 books every element as unaccounted. For a file, it derives
the file's fates from the bundle bytes (assets are named by content) and from
K1b.
## Finding A: why the guard refuses R761, and the decision
The cause is measured. The R761 XML carries **71 U+00AD SOFT HYPHEN** and no
other invisible codepoint, and the extracted text carries the same 71. Guard
1.4.0 lists U+00AD in `_ZERO_WIDTH_CPS` (`output.py:250`). One soft hyphen is
enough to fail_secure at both tiers; the same string without it is `clean`.
Image pointers are not the cause: `--no-assets` gives the same refusal, as the
PM also measured.
This is a question for the guard. It was sent to
`llm-ingestion-pipeline-security` with the repro, and nothing was built there.
**Decision on exit 0 when nothing was persisted:** `okf build` should NOT exit
0 when at least one document was extracted and none was persisted. The
conservation identity holding is necessary, not sufficient.
- This repository already refuses the analogous case: a run with zero plans
fails (exit 2) rather than emitting a flat bundle and calling it success.
- `okf build` is the trusted-source path, an operator pointing at their own
folder, where "everything refused" is a finding and not a normal outcome.
- A script running `okf build && okf skill` would otherwise wire a skill to an
empty bundle.
Door B's library function keeps its behaviour, because for a hostile inbox
"all rejected" is correct. The change is an exit code, which this order
forbids, so it belongs to the capability order and not here.
## Exceptions proposed, none approved
The gate lists three exceptions in every run. None of them lowers a
denominator:
- **PDF headings, paragraphs and tables.** A PDF without a structure tree
declares none of them, so no witness can count them.
- **xlsx images.** The reader deliberately does not carry them.
- **Images in md, txt, csv, json, odt and rtf.** No reader for these types
carries image bytes.
Approving any of them is the operator's decision.
## Output at this commit
See the order's closing message for the full text. In short:
| Row | Result | Status |
|---|---|---|
| 1 | 13 of 13 | GREEN |
| 2 | 0 of 13 | RED |
| 3 | 0 of 15, u = 248, d = 2 | RED |
| 4 | 0 of 1 | RED |
| 5 | 4 of 4 | GREEN |
| 6 | 59 of 110 (R761, two builds) | RED |
Row 6 runs two builds:
- **Default gate:** the document is refused, so every element is unaccounted.
- **`--gate none`:** the document is persisted, and the 50 pictures it points at
are both carried and rejected, which is finding B at scale (d = 50). A first
run reported 57: 7 of the 59 unpointed files share bytes with pointed ones,
and bytes in `assets/` had been credited to them. A file nothing points at
is never carried; a test holds that.
Row 7 (`--consume`) is a diagnostic and never fails.
## Limits
- The witness vocabulary is ours. A format element the witness does not name
is invisible to the gate.
- The fixture corpus is constructed, one document per type. The real-corpus
row is N = 1 (R761).
- Row 6 needs the R761 source on this machine. Without it the row is RED
locally and SKIPPED when `CI` is set, never green.
- The `--r761` default points into another repository's data directory, and
the gate only reads from it.

# The image path, second review: the bound bound a claim, not a cost
A second independent review, one day after the first, read `230d1cb` — the
commit that closed the two MAJOR findings of the `v0.10.0` review — and found
that one of the two was **not closed**. This is what that review found, what it
measured, and what this round changed. It is the round that makes `v0.10.1`
true; the round it corrects is
[`docs/2026-09-17-bildestien-0-10-1.md`](2026-09-17-bildestien-0-10-1.md), which
now carries a correction block where it claimed this defence.
## What was wrong: a declared size and a decompressed stream are two numbers
`check_size` read `/Width` and `/Height` out of a PDF image dictionary and
refused anything over `MAX_IMAGE_PIXELS`. Both numbers are written by the
document. `/Length` beside them is the **compressed** length, and nothing in
the dictionary states what `stream.get_data()` will return. A document that
declares `1 x 1` and hangs 400 MB of deflated zeros off it therefore passed the
check, paid the whole cost, and was **carried** as a one-pixel picture.
Measured on `230d1cb`, and re-measured here on `ed8d9d7` before anything
changed, with the same fixture in its own interpreter:
| stream inflates to | file size | declared | carried | rejection | peak RSS |
|---|---:|---|---|---|---:|
| 400 MB | 408 516 B | 1 x 1 | yes | none | **891 904 000 B** |
| 1,2 GB | 1 223 843 B | 1 x 1 | yes | none | **2 436 MB** (review) |
About 2 100x the file size, linear, so a 10 MB document is roughly 21 GB. It is
the failure mode the first review named — one document killing a batch build —
reached through the other number.
The first round's four mutations were all killed by its tests, and that told us
nothing about this: **not one of them separated a declared size from an actual
one**. A test built on an honest `20000 x 20000` declaration is green whether or
not the stream is bounded.
## What changed: three numbers are bounded, and the limit is stated
> **CORRECTION, 2026-09-18 (same day, later) — point 3 below bounded ONE LINK
> of a filter chain, not the chain.** A PM checkpoint of `0f308c1` measured

> all**: deleting it passed all 2 132 tests.
1. **What the container DECLARES** — unchanged from the first round.
2. **What a carried FILE measures** — new. `read_image` now checks the size it
sniffs out of the header. This package never decodes such a file, so it pays
nothing for it; but a 7 000 x 7 000 PNG of 47 705 bytes written into a bundle
hands the consumer the same bomb with `7000x7000 px` printed beside it, and
the README's first sentence about this bound said such an image was refused.
Over the 4 828 image objects of the reference corpus the largest is 18.6 MP,
so nothing measured is refused by this.
3. **What a PDF image's STREAM decompresses to** — new, and the finding.
`assets.inflated_size` inflates the raw stream a chunk at a time, keeps only
a running total, and **discards the output**, so the measurement cannot cost
what the bomb costs. It runs before `get_data()`.
**The limit is stated, not implied.** The stream measurement runs where
`FlateDecode` is the first filter and the document is not encrypted (the raw
bytes are ciphertext until pdfminer deciphers them). Every other filter chain is
caught by `check_payload(len(data))` **after** `get_data()` — a counted refusal,
not a bounded one: the memory is spent and then the picture is dropped. That
distinction is the whole substance of this round, so it is written in
`_check_inflated`'s docstring rather than left for the next reviewer to find.
A legitimate image is therefore inflated twice, once to measure and once to
carry. That is the price of not holding an unbounded buffer in order to find out
how big it is, **and at this sample it does not show**: three PDFs of the K2
reference corpus, 800 carried images between them, extracted twice in one
process with the measurement on and off.
| document | images | rejections | with the bound | without |
|---|---:|---:|---:|---:|
| Bilag 3.1 Miljøteknisk rapport | 464 | 0 | 18.21 s | 18.51 s |
| Bilag 1 Kravspesifikasjon | 311 | 12 | 16.28 s | 16.88 s |
| Bilag 3.3.1 Brannkonsept | 25 | 0 | 2.70 s | 2.35 s |
The bounded arm is faster on two of the three and slower on the third, which is
run-to-run noise rather than a speedup: the honest reading is that a second
inflate of these streams is **below the noise floor** of a PDF extraction that
is dominated by text layout. What is NOT noise is that the fate of every image
is identical on both arms — 464/464, 311/311 with the same 12 rejections, and
25/25 — so the bound refuses nothing these documents carry.
### A declared size that is not a size
`/Width -1 /Height 40000000000` multiplies to a **negative** pixel count, under
which every `>` bound reads as satisfied. `check_size` returned silently, 400 MB
was decompressed, and the refusal arrived from `encode_png` as
`asset_samples_invalid` — a code about a sample buffer, for a defect in the
declaration. A non-positive dimension is now **`asset_size_invalid`**, raised
before the stream is read.
It gets its own code rather than joining `asset_too_large` because the two say
different things about a document: a publisher shipping a picture larger than
this package carries is not a dictionary written to be read wrong, and counting
them together would make a corpus statistic about the first untrue. `None` stays
UNKNOWN — a container that declares no size leaves nothing to bound, and
inventing a number would refuse a legitimate picture.
### The line that says what is missing
Two smaller findings in the same line, both introduced by the first round's fix:
- **The address was written twice**, once in a code span and once bare, and a
GFM/linkify renderer autolinks a bare URL into `<a href>`. It takes a click
rather than a render, so it is weaker than `![...](...)` — but "inert" was
half true, and half is what that line exists not to be. Written once now.
- **The caption was dropped.** `label` stayed in the signature and no branch
read it, so the alt text or figure caption of an image the bundle does not
carry was lost — a regression against 0.10.0 and against the line's own stated
reason for existing (a reader cannot weigh an absence they were never shown).
It is written again, in the same `-- <label>` form a carried pointer uses.
## Measured after
Same fixture, same machine, same command, in its own interpreter:
| stream inflates to | file size | before | after |
|---|---:|---:|---|
| 400 MB | 408 516 B | carried, 891 904 000 B peak | **refused `asset_too_large`, 57 065 472 B peak** |
| 1,2 GB | 1 223 843 B | carried, 2 436 MB peak | **refused `asset_too_large`, 64 569 344 B peak** |
The bounded figure barely moves when the stream triples, because what grows is
the compressed input, which was already in memory. **The cost no longer scales
with the bomb**, which is the property the first round did not have.
End to end through the shipped CLI, default flags, the bomb beside one ordinary
markdown document so the build has a plan to write:
```
$ /usr/bin/time -l okf build /tmp/okf-r3/in --bundle /tmp/okf-r3/bb \
--bundle-id t3 --okf-version 0.2
exit=0
79650816 maximum resident set size
$ ls /tmp/okf-r3/bb/assets
ls: .../assets: No such file or directory
$ grep Images /tmp/okf-r3/bb/log.md
* **Images**: 0 carried of 1 found, ...
```
The review measured 838 000 640 B and an `assets/…-im0.png` written after it.
The concept says what stood there:
```
Image: page-1-Im0 (not carried: the stream behind 'page-1-Im0' decompresses to
more than 268435456 bytes from 407685 bytes of input, over this package's
bound; refused without being held, because the size a container declares is a
claim and this is the cost)
```
## The version
`v0.10.1` was going to be cut from a tree that said `0.10.0` in nine places: two
bound to each other by a test, and seven bound to nothing — four README install
lines telling a consumer to install the release before this one, two prose lines
about what that tag declares, the "current tag" entry, and a CHANGELOG whose
0.10.1 content sat under `[Unreleased]`.
Two new tests in `tests/test_packaging.py` bind all of them to
`llm_ingestion_okf.__version__`, plus the guard tag in the README to the one in
`[tool.uv.sources]`, which is the same class of instruction going stale. Proven
red in the intended way: bumping `__version__` and `pyproject.toml` alone turned
the first one red with `install lines name ['v0.10.0']`.
## Not measured
- **The 43-document reference corpus was not rebuilt.** The `render_missing`
change adds `-- <label>` to the line for an image a bundle does not carry, so
an assets-on corpus build differs on exactly those lines. That is the repair,
not a side effect, but its size across that corpus is unmeasured here. What
IS measured: **0 shipped artifacts move**. No bundle under `examples/`,
`skills/` or `tests/fixtures/` carries an image pointer of either kind — 0
occurrences of `Image: ` against a known-positive control on the same
directories — so both this change and the new `read_image` bound move zero
committed bytes.
- The pinned `K2-bundle-default-20260912` predates the image path entirely and
cannot move.
- The review's own "not measured" list stands: the content accounting after this
change, R761's `50 carried of 50`, docx/pptx/xlsx zip-slip, SVG as active
content, and the `[ocr]` path.

A PM checkpoint of `0f308c1` — the commit that was to make `v0.10.1` true —
read the fix for the deflate bomb and found the bound still reachable, through
a shape the fix had not considered: a PDF decodes a stream through a **list**
of filters, and the fix measured `filters[0]`.
This report records what was measured, what changed, and what the new rule
costs on real documents. The two rounds it follows are
[`docs/2026-09-17-bildestien-0-10-1.md`](2026-09-17-bildestien-0-10-1.md) and
[`docs/2026-09-18-bildestien-holder-0-10-1.md`](2026-09-18-bildestien-holder-0-10-1.md).
## BLOCKER — the bound measured one link of a chain
`_check_inflated` did this:
```python
filters = stream.get_filters()
if not filters or filters[0][0] not in LITERALS_FLATE_DECODE:
return
inflated_size(raw, name=name)
```
Two holes, and the second was invisible because the first looked like the
whole rule.
1. **A chain of two `FlateDecode` links passes the check.** The first link of
`/Filter [/FlateDecode /FlateDecode]` inflates 795 bytes to 407 685 — well
under the bound — and the check returns. `get_data()` then applies **both**
links and produces 400 MB.
2. **A chain whose first link is not `FlateDecode` is not measured at all.**
`[/ASCII85Decode /FlateDecode]` returns on the first line.
Measured on `0f308c1` in its own interpreter (peak RSS is `RUSAGE_SELF` of a
subprocess, not the high-water mark of the test session):
| chain | file | peak RSS | carried |
|---|---:|---:|---|
| `[/FlateDecode]`, 400 MB | 408 516 B | 59 232 256 B | 0, `asset_too_large` |
| `[/FlateDecode /FlateDecode]`, 400 MB | 1 636 B | **886 554 624 B** | 0, `asset_too_large` |
| `[/FlateDecode /FlateDecode /FlateDecode]`, 400 MB | 1 070 B | **889 393 152 B** | 0, `asset_too_large` |
| `[/FlateDecode /FlateDecode]`, 1,2 GB | 2 927 B | **2 567 204 864 B** | 0, `asset_too_large` |
About 543 000x the file size at two links. Note the last column: the picture
**is** refused — by `check_payload` after `get_data()`, which is the counted
refusal, not the bounded one. A test reading only the rejection code is green
on this defect, which is why two of the tests written here assert **which**
check fired, by its message.
The pre-fix figures were measured from a `git archive` of `3b587ea` on
`PYTHONPATH`, not from the editable tree, and the census below prints the
imported module's `__file__` as its own control.
## The chain is not a hypothetical
Every image XObject of the 78 PDFs on this machine, by filter chain
(2026-09-18, 5 142 objects, `get_filters()` as pdfminer resolves it):
| chain | objects |
|---|---:|
| `[/DCTDecode]` | 1 654 |
| `[/FlateDecode]` | 2 236 |
| `[/FlateDecode /DCTDecode]` | 596 |
| `[/FlateDecode /ASCII85Decode]` | 580 |
| (no filter) | 40 |
| `[/ASCII85Decode /FlateDecode]` | 16 |
| `[/JPXDecode]` | 16 |
| `[/CCITTFaxDecode]` | 4 |
1 192 real pictures are reached through a chain, so refusing every chain was
not available. 16 of them sit behind an `ASCII85Decode` and were unmeasured.
## What the rule is now
`_check_stream_cost` walks **every** link, in order, and the filters fall in
three classes (`extract.bounded_pdf_filters`, pinned by a test):
- `FlateDecode` is **measured** — inflated a chunk at a time, output
discarded, refused the moment the running total crosses the bound. A link
with another expanding link behind it is inflated **under the same bound**
and handed on, so what is held is never more than the bound.
- `ASCII85Decode` and `ASCIIHexDecode` **shrink** by construction (five
characters to four bytes, two to one), so their output is bounded by their
input, which is already in memory as part of the file. They are decoded here
so a `FlateDecode` behind one can be measured.
- `DCTDecode`, `JPXDecode` and `JBIG2Decode` are **pass-through** in pdfminer:
it hands the compressed image on for the reader to sniff, and the size does
not change.
Everything else — `LZWDecode`, `RunLengthDecode`, `CCITTFaxDecode`, `/Crypt`,
and any filter written after this — expands by an amount pdfminer will only
reveal by producing the whole output. On this machine that class is **4 of
5 142** objects, all `CCITTFaxDecode`, and all four are 1-bit stencil masks
(`/ImageMask true`, `/BitsPerComponent 1`) that the encoder already refused one
step later, twice over — so no picture anyone holds changes hands. An image behind one is refused
**unread**, with its own code `asset_pdf_unbounded`, and the refusal is
decided **before the first link is decoded**, so a document cannot make this
package pay for the links in front of the one it cannot bound. Refusing an
unknown name rather than passing it through is the same decision
`corpus.resolve_gate` takes for an unknown gate name: a fallback reproduces
the defect with an extra step.
An **encrypted** stream is deciphered and then measured. Deciphering does not
change a stream's length, so this is exactly what pdfminer's own `decode()`
does; before, `stream.decipher is not None` returned unmeasured, which made
"the document declares encryption" a way past the bound. That one is a
guarantee about the code and not a measured gain: **0 of the 5 142** image
objects on this machine sit in an encrypted document, so nobody here has ever
walked that path — which is exactly why nothing caught it.
Bounded, same fixtures, same machine:
| chain | file | peak RSS before | peak RSS after |
|---|---:|---:|---:|
| `[/FlateDecode]`, 400 MB | 408 516 B | 59 232 256 B | 62 017 536 B |
| `[/FlateDecode /FlateDecode]`, 400 MB | 1 636 B | 886 554 624 B | **52 367 360 B** |
| `[/FlateDecode x3]`, 400 MB | 1 070 B | 889 393 152 B | **61 390 848 B** |
| `[/FlateDecode /FlateDecode]`, 1,2 GB | 2 927 B | 2 567 204 864 B | **60 403 712 B** |
Both columns were measured on an otherwise idle machine, in paired
subprocesses, from the two pinned trees. The single-link row is the control:
it was already bounded and does not move. The cost no longer scales with the
bomb — tripling the stream leaves the bounded run where it was, because what
grows is the compressed input, which was already in memory.
An earlier pass of the same measurement, taken while two corpus censuses were
saturating this machine's memory, read 889 573 376 / 888 401 920 /
2 579 718 144 before and 94 748 672 / 91 258 880 / 107 921 408 after. The
unbounded column is the same number either way; the bounded one is not, which
is what a peak-RSS figure taken under load is worth. The figures published
above are the idle ones, and the test's own bar (`PEAK_RSS_BOUND`, 256 MiB)
sits above both.
## MAJOR — the backstop was uncovered
`check_payload(len(data), name=name)` after `get_data()` is the counted
refusal that four documentation surfaces point at. Deleting exactly that line
passed all 2 132 tests on `0f308c1`.
It is reachable: pdfminer's `decode()` sets `rawdata` to `None`, so a stream
something else has already decoded leaves nothing to measure, and the memory
is spent before this package is asked anything. That is now the **only** case
outside the bound, and it has a test. Under the deletion the refusal becomes
`asset_pdf_unsupported` — a code about a sample buffer, for a document that is
simply too large — which is what the test asserts against.
## The cost on real documents
Every PDF on this machine — 78 documents, the K2 reference corpus in both
`trinn1` and `trinn2`, the shipped fixtures and R761 Prosesskoden:2025 — was
run through `_pdf_images` page by page on both sides, and each side's census
was run from a **pinned tree** (`git archive 3b587ea` for before, a copy for
after) with the imported module's own `__file__` printed as the control. The
editable install was not on either path.
| | before | after |
|---|---:|---:|
| documents | 78 | 78 |
| images carried | **9 356** | **9 356** |
| `asset_pdf_unsupported` | 322 | 314 |
| `asset_pdf_unbounded` | 0 | **8** |
| `asset_samples_invalid` | 40 | 40 |
| documents losing an image they carried | — | **0** |
| documents gaining one | — | **0** |
Not one document loses a picture, and the comparison is by NAME rather than by
count, so a swap would show. The eight that move code are the four
`CCITTFaxDecode` stencil masks, counted twice because `trinn1` and `trinn2`
hold the same document: they were refused before and are refused now, one step
earlier and under a code that says why. No other rejection moves.
## Mutants
Eight mutations, one line each, in the class the order named. The harness runs
the unmutated tree first and asserts it passes, because a harness whose
command is broken reports every mutant dead and has measured nothing.
| mutation | verdict |
|---|---|
| only the first link is measured (the `0.10.1` rule restored) | DEAD |
| the link loop is dropped: only `filters[0]` is looked at | DEAD |
| the running total is compared the other way round | DEAD |
| an encrypted stream is skipped again instead of deciphered | DEAD |
| the backstop after `get_data()` is deleted | DEAD |
| a filter the bound cannot measure is passed through | DEAD |
| the intermediate link is measured but not carried forward | DEAD |
| the whole cost check is removed from the image path | DEAD |
## What this round did not do
- **No tag, no push.** The version stays `0.10.1` and untagged; re-measuring
is the PM's.
- **The accounting gate gained one line** — `asset_pdf_unbounded` in
`REJECTION_CODES` — which is what a new rejection code requires and nothing
more.
- **The 43-document reference corpus was not rebuilt.** The image census above
is per document and per image object, which is what this change can move;
whether any concept text moves is `render_missing`'s open question from the
previous round and is unchanged here.

# The content-accounting gate, hardened: the judge opens the bundle itself
2026-09-18. Raised by an independent adversarial review of `0b00de4`,
commissioned after the accounting was built. The review's
verdict was that the gate is "an honest RED today, but cannot be trusted as a
judge once it turns green": it was a calculator over a report the judged party
writes. This is what changed, measured.
Nothing in `src/` moved. The instrument was hardened; the thing it judges was
not touched.
## 1. BLOCKER B-1 — the gate never opened a concept file
`okf_accounting_gate.account()` compared BOOKED NUMBERS with the witness's
counts. Reproduced here before any code moved, as two tests over the real
fixture bundle: a report that changes not one byte of the bundle and books
every element as `carried` gave `GATE GREEN`, exit 0 — and so did booking
every element as `rejected`.
**The witness now gives every element the PIECES OF TEXT IT IS MADE OF, and
the gate looks for each of them in the concept bodies the run wrote.** Pieces
rather than one joined string, and that distinction is load-bearing: a reader
writes a heading's ATX marker and a picture's pointer block between the parts
of a container, so an STS `<sec>` is never one contiguous run in the bundle
even when every word of it is there. Measured — with one joined string per
element, 2 of the 13 fixture documents reported false losses; with pieces, 0.
The normalisation is the one the build already uses and no looser (strip
non-alphanumerics, casefold, remove a converter attribute block such as
`{.mark}`), and it is implemented in the gate rather than imported from
`accounting.py`: a judge borrowing the judged party's own comparison agrees
with it by construction.
Five more refusals, each driven from both sides by a test:
- a negative booking (`carried: 25, rejected: {x: -15}` of 10 read as clean);
- a document declared `persisted` that no concept in the bundle names;
- a document declared `rejected` that the bundle holds a concept from;
- a rejection code outside a closed list, at the document AND at the element;
- an `accounting_version` the gate does not read.
And: **a document the build PERSISTED whose report carries nothing from it is
never clean.** "Everything rejected" satisfied `u = 0, d = 0`.
**m-1:** an asset proved a carry by NAME, so a zero-byte file called
`<sha12>-x.png` read as a carry. It is now checked on the BYTES and on the
content address. The first attempt re-implemented the build's full naming rule
and reported **50 of 50** carried R761 images as missing — the build
lowercases the basename, folds separator runs and takes the suffix from the
bytes. The readable tail is the build's cosmetic choice and is deliberately
not reproduced here.
## 2. MAJOR M-1 and M-2 — what the witnesses could not see
Rows 2 and 3 require the build's inventory to EQUAL the witness's, so what the
witness does not count, nothing can lose visibly. Thirteen classes were added,
each with a red test first:
| format | now counted |
|---|---|
| `.docx` | header/footer, comment, endnote, text box |
| `.pptx` | speaker note, hidden slide (`show="0"`, no longer an ordinary slide) |
| `.xlsx` | formula, hidden sheet |
| `.odt` | header/footer (they live in `styles.xml`), annotation |
| `.xml` | `mixed-citation`, `mml:math`, `fig`, a figure's caption |
| `.pdf` | the page's own TEXT (it counted pages and picture placements only) |
A text box's paragraphs are the box's own, or the text is booked twice. A
hidden sheet's state lives in `workbook.xml` and is reached through the
relationship id, so the sheet part itself says nothing about it. An annotation
counted as prose makes the accounting demand that a reader carry a note the
author wrote to themselves.
**M-2:** the two STS witnesses shared ONE role map, so row 5 — "two witnesses
agree" — could not see a hole in it. They are written apart now. Measured on
R761 2026-09-18: the XML delivery places a section's label at `sec/label`
**7 714** times and inside a title **0** times; the JSON delivery puts
**2 760** of them inside the title. The XML map was narrowed to the XML fact,
and a JSON twin fixture carrying the nested placement holds the difference
live — without it, swapping the maps changed nothing measurable.
## 3. MAJOR M-3 — 20 of 63 element types had a count of zero
A witness cannot be caught being wrong about something it never sees; that is
why six of seven witness mutants survived the original suite. Seven hand-built
documents close it (`tests/fixtures/accounting/make_accounting_fixtures.py`),
every element type now occurs at least once, and **all twenty documents carry
a hand count** read off the fixture's own bytes — four did before. The
operator's own proposed `.xlsx image` exception could not be exercised at all
until now.
Building them found three defects in the fixtures themselves, each of which
would have reported a loss the build never had: a shared string table not
related to the workbook (every `t="s"` cell converts empty), a `graphicData`
with no `uri` (pandoc does not see a table), and an `odt` `styles.xml` without
`<office:styles/>` (pandoc refuses the document).
## 4. Row 6 and the verdict line
- **R761 refused whole under the default gate is now RED.** It was GREEN with
31 096 of 31 096 elements booked as coded rejections and `okf build` exiting
1 unseen: every element had a fate, so `u = 0, d = 0`. The row asks the
question separately now.
- **A skipped row never leaves the verdict unqualified.** `GATE GREEN` now
reads `GATE GREEN (row 6 not run: <reason>)`, and the exit code is non-zero
locally when a corpus source exists on the machine and the row did not run.
- **N200 Vegbygging:2024 is a second real corpus.** R761 holds **0** `fig`,
**0** formulas and **0** references, so the gate's only real corpus could not
have found the hole in the role map. N200 carries **194** citations, **49**
figures and **135** footnotes. A `.json` file whose root carries an STS node
tree is counted as STS rather than as keys and leaves — the container is not
the content.
## 5. MAJOR M-4 — mutation
The review's 26 mutants, ported to the code as it stands, plus 8 written for
the new checks: **34 of 34 killed** (21 of the review's 26 were killed before
the last seven tests were added; all 26 are killed now, against the order's bar
of 23). The harness is `tools/okf_gate_mutants.py`, it runs on a copy of the
tree, and **a pattern that does not match is an ERROR and exit 2** — a mutant
that could not be applied was never measured, and counting it as killed is the
same mistake as reading an empty search as an absence. That fired once, on
M13, after a refactor moved the line it edits.
## 6. The gate is REDDER than before, and that is the movement
At the shipped defaults, `python3 tools/okf_accounting_gate.py`, 3 m 51 s:
```
1 file types with a fasit fixture | 13 of 13 | GREEN
2 source inventory before build | 8 of 13 | RED
3 accounting after build | 17 of 22 | RED
4 a rejected document is reported | 1 of 1 | GREEN
5 two witnesses agree | 4 of 4 | GREEN
6 real corpora | 110 of 111| RED
GATE RED: rows 2, 3, 6
```
Row 3: **u = 19 unaccounted, d = 2 double-booked, 0 booked carried and not in
the bundle, 0 declarations the gate refuses** — and **314 carried elements
FOUND in the bundle**, 6 carrying no text the gate can check. The zero matters
as much as the nineteen: nothing the build DOES book as carried failed the
bundle check, so every red is the build's and none is the instrument's.
**The new "not carried" classes, per file type, with counts on the fixtures** —
the raw material for the next capability order and for the operator's
exception list:
| file type | not carried | on the fixtures |
|---|---|---|
| `.docx` | comment, endnote, footnote, header/footer, text box | 1, 1, 1, 2, 1 |
| `.odt` | annotation, header/footer, image | 1, 2, 1 |
| `.pptx` | hidden slide, speaker note | 1, 1 |
| `.xlsx` | formula, hidden sheet, image | 1, 1, 1 |
| `.xml` (STS) | citation, figure, figure caption, math | 1, 1, 1, 1 |
Two are DOUBLE-booked rather than lost: a hidden slide and a hidden sheet are
carried into the bundle but booked as an ordinary slide and an ordinary sheet.
A third is a genuine double count in this package: **a text box's paragraph is
counted twice**, once inside the box and once in the paragraph carrying it.
On the real corpora: R761 under `--gate none` is **31 081 carried elements
found in the bundle, 0 claimed and not found, 65 the gate cannot check**, over
a document holding 31 096. N200 is **16 549 elements with no fate at all**,
because `okf build` exits 2 on it (see § 7).
`okf build --accounting` over the fixture corpus now exits 1 with **6
unaccounted** in the build's OWN vocabulary — its first real finding, and it
only became reachable when the fixtures carried the constructs.
## 7. Two facts about `okf build` this run establishes
**R761 is felled 100 % by ONE rule, and it is not tier-dependent.** The
document is refused whole under the default `guard-trusted-source` with
`fail_secure`. Asked directly, guard 1.4.0 answers
`any-tier: invisible carrier (output:zero-width-present)`, severity HIGH,
assessment SEVERE — and `PRESET_USER_UPLOAD` gives the same disposition, so no
tier this package offers persists it. The cause is measured rather than
inferred: the document carries **71 U+00AD soft hyphens**, and removing them
takes the same text to `WARN`, which persists. Whether that is intended is
below.
**N200 gets 0 plans and exit 2.** The JSON delivery is fenced verbatim, so no
line-anchored boundary grammar fires — the same behaviour a structureless
`.txt` produces, documented in `CLAUDE.md`. It is not an accounting defect, and
the gate reports it as what it is: 16 549 elements with no fate.
## 8. What this gate still cannot check
Printed on every run, beside the verdict, because a gate that reports only the
build's gaps invites a green row to be read as a guarantee:
- a short element often stands elsewhere in the same document, so finding it
proves it is present and not that THIS one is;
- two pointed files with identical bytes are one content-addressed asset, so
one of them losing its pointer is invisible here (m-5);
- an image embedded in a binary container has no source file to hash;
- absence is never verified: an element booked REJECTED is not looked for;
- the witness is a second implementation of the same definitions, so a
definition that is wrong for a format is wrong on both sides at once.
Every witness also prints, per file type, the named list of what it still does
not count. `APPROVED_EXCEPTIONS` was read by no row at all (m-3); each pair is
now checked against the witness's vocabulary and the run says, per pair, why it
moves no denominator — and would say `WARNING` if one ever did.
## 9. Reproduction

# A budget per link, and a property over every chain
A PM checkpoint of `0c3c490` — the commit that bound every link of a PDF
filter chain — read the fix and found the bound still reachable. This is the
third round of the same review, and the third time a bound was put on an
**output** and the bomb stepped one link along.
The two rounds before it are
[`docs/2026-09-17-bildestien-0-10-1.md`](2026-09-17-bildestien-0-10-1.md),
[`docs/2026-09-18-bildestien-holder-0-10-1.md`](2026-09-18-bildestien-holder-0-10-1.md)
and [`docs/2026-09-18-filterkjeden-og-backstoppen.md`](2026-09-18-filterkjeden-og-backstoppen.md),
which carries a correction block pointing here.
## The finding is the pattern, not the filter
| round | what was bound | where the bomb moved |
| --- | --- | --- |
| 1 | the size the dictionary DECLARES | into the stream |
| 2 | the first `FlateDecode` link | into the second link |
| 3 | every `FlateDecode` link | into a link documented as safe |
Round 3 shipped a three-class split in which `ASCII85Decode` and
`ASCIIHexDecode` were "bounded by their own input because they shrink". That
sentence is false in two independent ways:
* **ASCII85 does not shrink.** `z` is its shorthand for four zero bytes, so
one input byte becomes four. The output ratio is 4, not 0.8.
* **The output is not the cost.** `base64.a85decode` appends one 4-byte object
per group to a list, so a run of `z` costs about a hundred bytes of memory
per byte of INPUT. Measured on CPython 3.14: **101.4x** at 1 MiB of input,
**96.1x** at 4 MiB, **94.5x** at 16 MiB. Nothing in the output size says so.
The second point is the general one, and it is why this round does not add a
fourth class. A bound on what a link OUTPUTS is not a bound on what producing
it COSTS, and every round of this review has been an instance of that.
## BLOCKER — reproduced
Measured in paired subprocesses on an idle machine, both sides from pinned
trees (the `before` side from `git archive` of `0c3c490`, the `after` side from
a snapshot of the working tree), each printing the module's own `__file__` as
a control. The document is built ONCE by a third process and read from a file:
`ru_maxrss` is a high-water mark that never falls, so a child that builds its
own fixture reports the fixture — `b"z" * (64 MiB)` alone costs 171 MB, more
than the bounded extraction it would be measuring. This tripped the first
attempt at these figures.
| chain | file | before | after |
| --- | --- | --- | --- |
| `[/FlateDecode /ASCII85Decode]`, `z` × 32 Mi | 33 475 B | **carried**, 3 261 599 744 B | `asset_too_large`, **42 070 016 B** |
| `[/FlateDecode /ASCII85Decode]`, `z` × 64 Mi | 66 090 B | **carried**, 6 461 558 784 B | `asset_too_large`, **40 280 064 B** |
| `[/ASCII85Decode]`, `z` × 8 Mi | 8 389 449 B | **carried**, 933 085 184 B | `asset_too_large`, **62 484 480 B** |
| `[/Fl /A85 /Fl]`, `z` × 32 Mi | 33 488 B | `asset_samples_invalid`, 3 519 180 800 B | `asset_too_large`, **43 438 080 B** |
Two things to read off it. The picture was **carried** in three of the four
rows — this was not a bound that fired late, it was no bound at all. And the
bounded cost does not follow the bomb: doubling the run of `z` takes the old
cost from 3.26 GB to 6.46 GB and the new one from 42.1 MB to 40.3 MB.
## The rule: a budget per link, and it travels
`assets.MAX_FILTER_DECODE_BYTES` (512 MiB) is what decoding ONE link may cost.
It is a separate number from `MAX_IMAGE_BYTES` (256 MiB) on purpose: that one
bounds the picture this package will carry, this one bounds what producing it
costs on the way.
`assets.PDF_FILTER_COST_RATIO` gives each permitted filter a **measured**
worst-case peak memory per byte of input. `None` means the decoder is driven a
chunk at a time here, so the cost is measured as it is paid — today that is
`FlateDecode` alone.
| filter | cost ratio | measured |
| --- | --- | --- |
| `FlateDecode` | — | driven a chunk at a time (`assets._inflate`) |
| `ASCII85Decode` | 104 | 101.4x / 96.1x / 94.5x at 1 / 4 / 16 MiB of `z` |
| `ASCIIHexDecode` | 2 | 1.5x at 16 MiB |
| `DCTDecode`, `JPXDecode`, `JBIG2Decode` | 1 | pass-through in pdfminer |
Everything else — `LZWDecode`, `RunLengthDecode`, `CCITTFaxDecode`, `/Crypt`,
anything written later — has no measured ratio and is refused UNREAD with
`asset_pdf_unbounded`, before any link in front of it is decoded. That is the
same decision `corpus.resolve_gate` takes for an unknown gate name: a fallback
reproduces the defect with an extra step.
The budget **travels down the chain**. A `FlateDecode` link's output is the
next link's input, so it is inflated under a limit that is the smaller of
`MAX_IMAGE_BYTES` and what the next link's decoder may be handed
(`assets.inflate_limit_for`). Without that, `[/FlateDecode /ASCII85Decode]`
would inflate 256 MiB of `z` before the link behind it was asked anything.
### Why an input cap and not a bounded ASCII85 decoder
A chunked ASCII85 decoder written here would bound `_check_stream_cost`, and
it would not bound the run: pdfminer decodes the whole chain again in
`stream.get_data()`, with its own unbounded decoder, and that is where the
memory is actually spent. The only number that bounds *that* is the size of
the input this package allows the link to be handed. Writing our own decoder
would also make this package, rather than pdfminer, the authority on what an
image's bytes are.
### Why not a hard backstop in a child process
The order asked for `resource.setrlimit(RLIMIT_AS)` to be MEASURED before
anything was built on it. It was, and it is not available here: on this
machine (Darwin 26.6.2, CPython 3.14) `setrlimit(RLIMIT_AS, (256 MiB, hard))`
raises `ValueError: current limit exceeds maximum limit` — a fresh CPython
process has already reserved far more address space than the cap, and the hard
limit reads as `RLIM_INFINITY`. The documented behaviour agrees: Darwin does
not enforce `RLIMIT_AS`, `RLIMIT_DATA` or `RLIMIT_RSS` the way Linux does. So
no child-process memory cap was built, and the bound is the per-link budget
alone.
## The cap is read off the corpora
The cap that falls out for `ASCII85Decode` is 512 MiB / 104 ≈ **5.0 MB** of
input. Measured 2026-09-18 over the **9 668 image objects of the 77 PDFs on
this machine** (enumerated through pdfminer's own page walk):
| chain | objects |
| --- | --- |
| `[/FlateDecode]` | 6 235 |
| `[/DCTDecode]` | 2 459 |
| `[/FlateDecode /DCTDecode]` | 596 |
| `[/Fl]` | 296 |
| unfiltered | 42 |
| `[/ASCII85Decode /FlateDecode]` | 16 |
| `[/JPXDecode]` | 16 |
| `[/CCITTFaxDecode]` | 8 |
**16** objects decode through an `ASCII85Decode` link, and the largest input
any of them is handed is **450 739 bytes** — more than ten times under the
cap. That is the posture `MAX_IMAGE_PIXELS` has: a number read off the corpora
and standing an order of magnitude above anything measured, so the bound costs
no picture anybody has.
Two corrections to earlier published counts fall out of this table, and both
are about ENUMERATION rather than about the documents. The round-2 report
counted 5 142 objects over 78 PDFs and **580** behind `[/FlateDecode
/ASCII85Decode]`. This walk finds 9 668 objects over 77 files and **0** behind
that chain. The denominators differ because the two walks are different (this
one recurses into `LTFigure`; the file R761 is not in this listing), so
neither number is wrong about a document — but a chain count is only readable
beside the walk that produced it, and the `[/Fl /A85]` group is not one this
machine's corpora hold. The bomb that shape carries is real regardless: a
document does not have to exist in a corpus to be handed to `okf build`.
## The property test
`tests/test_asset_limits.py::test_no_chain_of_up_to_three_filters_is_carried_over_the_bound`
generates **every** chain of length 1–3 over the ten filters pdfminer decodes
— `K = 1 110` — twice, once with a payload of zeros (the amplifying case at
both ends: it deflates to nothing and `a85encode`s to a run of `z`) and once
with a repeated non-zero byte. Each chain's stream is built by encoding the
payload BACKWARDS through the chain, so every chain over the permitted filters
is a valid document rather than a rejection by accident.
The requirement is one sentence: the picture is either delivered with its
bytes under the bound, or refused with a code in the published vocabulary;
never carried over the bound, and never paid for on the way. `tracemalloc`
measures the paying, because it counts Python's own allocations — which is
exactly where `a85decode`'s cost lives, and unlike `ru_maxrss` it is not
disturbed by other work on the machine.
Result: **1 110 of 1 110** chains pass, both payloads — `k = K`.
Beside it, `test_every_bounded_chain_still_carries_a_small_image` runs the
**258** chains over the six permitted filters with a 64-byte image and
requires none of them to be refused. A rule that refuses everything passes the
property alone; it does not pass this.
And `test_the_ascii85_cost_ratio_is_not_below_the_one_this_package_measured`
re-measures the ratio the budget rests on, in a subprocess, at two input
sizes. If CPython ever changes `a85decode` so that it costs more, the constant
is too generous and this says so before a corpus does.
## MAJOR — the backstop had no test
`check_payload(size, name=name)` at the END of `_check_stream_cost` could be
deleted with the whole suite still passing. It is what refuses a stream no
filter in the chain expands — an unfiltered one, or one behind `DCTDecode` —
and the SECOND `check_payload`, after `get_data()`, produces the same code and
the same words one step later. A test that reads the code cannot tell the two
apart.
What separates them is whether the payment was made, so the test asserts
`get_data` was never called.
## Mutants
Ten mutations, one line each, run in a scratch clone with the unmutated copy
run FIRST as a control. The peak-RSS subprocess tests are deselected for these
runs — they measure a high-water mark and the machine was running a corpus
census — so what kills a mutant here is the property test, the code
vocabulary, or an assertion about which check fired.
| mutation | one line | killed by |
| --- | --- | --- |
| `backstop-deleted` | `check_payload` at the end of `_check_stream_cost` removed | `test_the_stream_bound_refuses_before_get_data_is_ever_called` |
| `cost-check-deleted` | the per-link `check_filter_cost` call removed | the property test, both fills, + `[/ASCII85Decode]` |
| `ascii85-budget-removed` | that filter's ratio set to `None`, so it gets no budget | 9 tests, including both ratio measurements and the corpus cap |
| `ascii85-ratio-is-one` | the ratio set to 1 instead of the measured 104 | 6 tests, including both ratio measurements |
| `budget-does-not-travel` | `inflate_limit_for` returns `MAX_IMAGE_BYTES` always | `test_the_budget_travels_to_the_next_link` |
| `widest-output-ignored` | `_widest_output` returns its input unchanged | `test_a_discarded_links_size_travels_as_the_widest_it_could_become` |
| `first-flate-not-last` | the discard happens at the FIRST deflate link | 5 tests, including both round-2 chain bombs |
| `unknown-filter-passes` | a filter with no ratio is let through instead of refused | `test_a_filter_the_bound_cannot_measure_...`, `test_asset_pdf_unbounded` |
| `budget-a-hundredfold` | `MAX_FILTER_DECODE_BYTES` multiplied by 100 | 4 tests, including both new bombs |
| `cost-check-off-by-a-factor` | the comparison allows 1 000x the limit | `test_an_ascii85_link_on_its_own_is_bounded` |
**10 of 10 killed.** Four of them survived a first pass and are the reason two
of the tests above exist: `budget-does-not-travel` and `widest-output-ignored`
had no test at all, and `budget-a-hundredfold` and
`cost-check-off-by-a-factor` were only reachable through the peak-RSS
subprocess tests that first pass had deselected. A mutant that survives is a
test that was missing, not a mutation that was unfair.
## Cost to real documents
Measured by name, not by total: `_pdf_images` run over every PDF on this
machine from each of the two pinned trees, each printing the module file it
loaded as a control, and the per-file counts compared.
| corpus | files | carried before | carried after | files whose count moved |
| --- | --- | --- | --- | --- |
| `~/corpora` + `tests/fixtures` | 77 | 9 306 | **9 306** | **0** |
| R761 Prosesskoden:2025 | 1 | 50 | **50** | **0** |
| both | 78 | 9 356 | **9 356** | **0** |
The rejection codes are identical too — `asset_pdf_unsupported` 314,
`asset_pdf_unbounded` 8, `asset_samples_invalid` 40 on both sides, and **0
files** where any per-file code count moved. Not one picture changes hands.
That is what the cap being read off the corpora buys: the only new refusal is
`check_filter_cost`, and the largest `ASCII85Decode` input any of these
documents holds is 450 739 bytes against a cap of about 5.0 MB.
The two trees are `git archive` of `0c3c490` and a snapshot of the working
tree taken before the prose edits; `diff -r` between that snapshot and the
committed tree touches docstrings and comments only, so what was measured is
what shipped.
R761 also settles the `[/FlateDecode /ASCII85Decode]` question the PM raised
while this order was open: **50 image objects, 29 `[/DCTDecode]` and 21
`[/FlateDecode]`, and 0 ASCII85 links.** So that chain is in neither the 77
corpus files nor R761, and the round-2 report's count of 580 is not
reproducible from anything on this machine. It changes no decision here — the
bomb that shape carries does not need a corpus to exist in — but a published
count that cannot be reproduced should not stay unqualified.
## What is still not bounded
Unchanged from round 2, and stated rather than implied: a stream something
else has already decoded (`_pdf_stream_bytes` returns `None`), where the
memory is spent before this package is asked. `check_payload` after
`get_data()` COUNTS it — a counted refusal, not a bounded one.

# The BMP rest: a terminator, and a claim that has to come from a pointer block
2026-09-19. Two defects PM's checkpoint on `c39b666` found in the
viewable-asset round, both shipped, both with the default flags. The round
that introduced them was judged PARTIAL; this closes the two load-bearing
rests and the two small ones. No new format, no new dependency, no version
bump and no tag.
## 1. A truncated RLE8 stream was carried, silently
`_bmp_rle8_rows` painted what the stream held and left the rest of the frame
at palette index 0. That is what the format says about a pixel a delta
SKIPPED, so no decoder disagrees — every one of them agrees on the wrong
picture. Measured by PM on a real R761 asset, `1631e526275d-7-graphic-0003.bmp`,
352x548 = 192 896 pixels:
| cut | result |
|---|---|
| stream truncated to 90 % | carried, 13 923 pixels wrong, no code, no row |
| to 50 % | carried, 95 890 wrong |
| to 10 % | carried, 166 525 wrong |
The uncompressed path already refused the same shape
(`asset_samples_invalid`, "refusing to pad, because a short buffer means the
header was read wrong"). Eval point 6 of the round's own order says "corrupt
-> published code, never silent"; this was the one place it did not hold.
### The rule, read off the corpus rather than chosen
The order named two candidates — compare available bytes against
`biSizeImage`, or require an end-of-bitmap escape. Measured first, over the
19 real RLE8 assets of the frozen R761 delivery (`~/corpora/po-frosne-bundles/
r761-2025-58e1ecca6007/assets`, read only):
```
denominator (RLE8 files): 19
stream reaches an explicit EOB: 19 of 19
the EOB is the stream's LAST 2 bytes: 19 of 19
biSizeImage == available bytes: 19 of 19
bytes after the EOB: Counter({0: 19})
```
Both candidates are satisfied by every real file, so the choice is made on
what each MEANS. `biSizeImage` is a claim by the same untrusted header that
declares the size; the terminator is a statement inside the data that the
picture is complete. A third candidate, requiring every pixel to be painted,
is wrong by construction: it would refuse the delta escape the format
defines. So the decode may end at an explicit end-of-bitmap and nowhere else,
and a stream that runs out first is refused with `asset_samples_invalid`.
A stream that is WHOLE but omits the terminator is refused alongside a cut
one. From a reader's side they are the same bytes, and the measurement says
no writer in this corpus produces the first.
### Nothing real changes hands
The same 19 files still convert losslessly after the rule: **19 of 19,
2 366 365 pixels compared** — PM's own figure, re-measured here with stdlib on
BOTH sides (an independent BMP reader and an independent `zlib` +
filter-reversal PNG decoder, no Pillow anywhere), with a one-byte control
proving the comparison can fail.
The guard in the suite is pinned to a decoder written in the test file, which
computes what each cut costs: 8, 11, 17, 0 and 0 of 32 pixels. **Two of the
five cuts lose no pixel at all**, which is the whole reason the rule has to be
the terminator and not a pixel count.
## 2. The judge's new route could be forged by the document
`asset_holds` gained a second route in the viewable-asset round, because a
converted image's own bytes are not in `assets/` and never will be. It reads
the two digests the bundle states on the pointer line — with an expression
that ran over the WHOLE bundle text. So a document could write the sentence
itself. Measured by PM, and reproduced here before any code moved:
```
the 50000x50000 BMP was REFUSED and is not in assets/: True
judge asset_holds(refused BMP) = True (via the image's alt text)
forged via PLAIN BODY TEXT -> asset_holds(refused BMP) = True
```
Before that route existed, `asset_holds` hashed the source file and looked in
`assets/` — nothing a document wrote could reach it. The gate's own first
sentence is THE FASIT NEVER COMES FROM THE READER IT JUDGES, and `claimed and
not found` had become something a document could ask to have silenced.
### Two halves, and neither is sufficient alone
**The judge** reads the clause only from inside a pointer block — the markdown
image line plus the detail line under it — and only where the clause names the
asset that block points at. That closes ordinary body text and a table cell.
It cannot close an image's own `alt` text, because a LABEL is document text
that the build writes INSIDE a pointer block.
**The door** is `assets._inline`, and this is where the boundary runs:
everything it returns came from the document (an `alt` attribute, an STS
caption, a publisher's file name); everything `render_block` appends after it
came from the run (the size it measured, the type it sniffed, the digests it
computed). The second line carries both, so document text may not emit the
metadata grammar the run writes there. A checksum field is disarmed: the
digits are kept, because a reader is owed what the document said, and the
colon that makes them a FIELD is not.
### The mutants, and one finding about the harness
Three mutants in `tools/okf_gate_mutants.py`, one per check, each felled by
its own arm: the pre-round `_conversions` restored verbatim (X3), the
asset-name tie dropped (X4), `_inline`'s disarming dropped (X5).
**X5 survived 112 green tests on its first run, and had never been applied.**
The harness copies the tree and runs pytest in the copy with the venv's
interpreter — which carries an EDITABLE install pointing at the working tree,
so `import llm_ingestion_okf` in the copy resolved to the original `src/`. The
subprocess now gets the copy's own `src/` on `PYTHONPATH`, which wins over the
editable finder, and X5 dies on the first run under it. The gate and the
witness were never affected: the suite reaches those through the copy's own
`tools/`.
`killed 39 of 39, exit 0` (36 before this round).
## 3. Two small rests
**The judge proves carriage, not fidelity.** PM's M10: a mutated converter
writing a BLANK PNG gives `asset_holds = True`, because the bundle is
internally consistent — the digest it claims to have written really is the
asset's digest. The suite fells that mutant by decoding both sides; the gate
cannot. The docstring now says so, and the limit is asserted in BOTH
directions: a test shows the blank PNG is accepted AND that the docstring
names the gap. Teaching the judge pixels is a different job.
**The lossless guard now runs on a core install.** It decoded through Pillow,
which this package neither uses nor ships and which arrives only as a
transitive dependency of `pdfplumber` under `[extract]`. Measured by PM on a
core environment: 4 of the 13 guards in `tests/test_asset_viewable.py` were
SKIPPED, the lossless one among them, so a plain `pip install
llm-ingestion-okf` never measured the property the round is named after. The
new arm decodes the carried PNG with `zlib` and the five PNG SS 9.2 filters
and compares against pixels written out in the test file, over `read_image`
and over what the BUILD wrote. The environment is MADE rather than assumed: a
`sys.meta_path` finder raising for every `PIL` name, with a known-positive
that it fires. Control, run once and not committed: a Pillow-dependent line
placed inside the blocked section turns the guard red.
## 4. Two checks this round introduced and then removed
Both were measured and found unkillable, and a guard nothing can fell is not
a guard.
- The end-of-line anchor on the judge's clause expression. With the
pointer-block route and the asset-name tie in place, the only case it covers
is a label forging a clause inside a block that also carries a real one —
which `_inline` makes unreachable from a document. The whole gate suite is
green without it.
- The length check on a short absolute run in `_bmp_rle8_rows`. Unobservable
by construction: a run shorter than its declared count means the stream ran
out, so the loop cannot reach an end-of-bitmap afterwards and the picture is
refused either way. Measured in a scratch copy, both directions: **95 passed
with the check, 95 passed without it**, so the mutant that removes it
SURVIVES. The order asked for that mutant; this is the answer to it.
A fifth cut replaces them and makes an existing bound load-bearing: a stream
cut in the middle of a delta escape, 17 of 32 pixels wrong. Without the
two-byte bound in that branch it raises `IndexError` instead of a coded
refusal.
## 5. What this round did NOT measure
- The 43-document reference corpus was not rebuilt. The accounting gate's
rows are unchanged (`GATE RED: rows 2, 3, 6`, row 3 identical at u = 19,
d = 2, 17 of 22) — the operator-accepted losses of 2026-09-17.
- No R761 end-to-end build was run this round; the 19-file lossless
measurement is over the frozen delivery's own assets, which is the input
that half of the build.
- 16 JPEG 2000 objects are still lost with a line in the concept, and WebP is
in the viewable set while `sniff` does not recognise one. Both are stated
limits from the previous round and neither moved.

# The end-of-line stream that paints nothing, and four smaller rests
2026-09-19. PM's checkpoint on `44ad845` judged the previous round PARTIAL
with no load-bearing rest and five small ones. Four are code and one is
arithmetic in a closing message. This closes all five. No new format, no new
dependency, no version bump, no tag, and not one byte of any bundle moves --
measured, not asserted.
## 1. The rest that was a rule and not a sentence
The round before wrote a cursor rule into `_bmp_rle8_rows` and, beside it, a
sentence:
> a delta escape and an end-of-line escape both leave pixels at index 0 and
> every decoder agrees on them, because the stream stated the skip
PM measured it false for the end-of-line half: four end-of-line escapes and an
end-of-bitmap carry an 8x4 frame with **32 of 32** pixels never decoded, and
Pillow -- the independent decoder that file names -- refuses the same bytes.
The order offered two options: refuse a stream that reaches the end of the
frame without painting (recommended), or write the sentence true. **Both were
measured before either was chosen**, and the recommendation does not close the
class.
### 1.1 The class, swept rather than curated
Twice now this defect has been closed one construction at a time -- a
truncated stream, then an immediate end-of-bitmap -- and twice the class
stayed open one step down. So it was enumerated: every opcode sequence of
length 1 to 4 over twelve opcodes on a 4x3 frame, **22 620 streams** (encoded
runs that fit and runs that do not, absolute blocks, end-of-line, five
deltas), each decoded by this package and by Pillow.
| rule | carried here, refused by Pillow | carried by both, drawn differently | real RLE8 files carried |
|---|---|---|---|
| before this round | **703** | **1 492** | 25 of 25 |
| + refuse when nothing was painted (PM's recommendation) | 512 | 1 171 | 25 of 25 |
| + refuse an end-of-line at column 0 | **0** | 1 118 | 25 of 25 |
| + refuse a delta out of its row | **0** | **32** | 25 of 25 |
| + refuse a run that overruns its row | 0 | 0 | **10 of 25** |
The recommendation on its own would have narrowed the class for the third
round running. The last row is the one that cannot ship.
### 1.2 Why the end-of-line, and why the delta
Pillow's RLE8 decoder is a flat accumulator: an end-of-line pads its buffer to
the next row boundary, so an end-of-line at column 0 adds NOTHING, while this
reader advances a whole row. A delta appends `dx + dy * width` bytes, which is
the same skip this reader makes -- as long as `dx` stays inside the row.
So the two clauses are the two places where a stream can move this reader's
cursor without stating a skip another reader follows:
* **an end-of-line escape at column 0.** It closes no row, so the row it
passes over is a row the stream never wrote.
* **a delta whose horizontal offset would leave the row.** The format puts
that offset inside the line; this reader keeps the cursor past the row end
and a flat decoder rolls it into the next row. Two pictures, one stream.
Both refuse with `asset_samples_invalid`, the code the path already uses.
### 1.3 What is NOT closed, and what closing it would cost
All **32** residual disagreements are a run or absolute block that OVERRUNS
its row -- clipped at the row end here, spilled into the next row by Pillow.
Refusing those gives 0 and 0 and costs **15 of the 25** real RLE8 files: 15
real figures dropped and a pinned bundle's bytes moved. It is stated in the
docstring, in the test and here, and it is not taken.
### 1.4 The corpus, measured first and measured again
Over **11 441** files scanned across the four raw standard deliveries and the
K2 reference corpus, the only BMPs on this machine are R761's **25** (24
distinct), all RLE8. Of those:
```
end-of-line at column 0 : 0 of 25
delta escape (any) : 0 of 25
run overruns its row : 15 of 25
```
So both shipped clauses cost nothing measured, and after the change **25 of
25** still decode to Pillow's pixels exactly -- **3 117 220** pixels compared,
byte for byte, with the two readers independent on both sides.
## 2. The arms the table could not see
`CURSOR_CASES` goes 8 to 12. One arm per CLAUSE of the cursor rule: the ROW
clause had none, because every short stream in the table stops on the last
row, which is why PM's `P8` (`height - 1` -> `height - 2`) survived 51 tests.
The new arm stops one row early with that row complete. Three more arms are
the end-of-line class.
The table is CURATED and stays that way -- every arm in it is one where the
two readers agree -- and the general relation between them is now held by the
sweep, which asserts the direction that matters (nothing carried here is a
file the other decoder refuses) and requires every residual disagreement to be
an overrunning run, computed in the test by a walker written there.
`P8` and `P13` (the end-of-line clause removed) join the mutant runner:
**killed 47 of 47**, exit 0.
## 3. The contract a consumer implements the door from
`tools/okf_accounting_gate.py` publishes the `--accounting` JSON a consumer is
expected to write. It did not name `conversions` -- which `asset_holds`'
conversion route now DEPENDS on -- nor `normalised_soft_hyphen`, `unaccounted`
or `double_booked`. A door built from that contract writes a ledger this gate
reads as "nothing was converted", and every converted image comes out
claimed-and-not-found: **19 of 50** on R761.
Two tests hold the sketch, one per direction:
* what the gate READS. The ledger is handed to `_declared_conversions` as a
mapping that records every lookup at any depth, so the assertion is about
lookups and not about grep -- grep reads a rejection code as a JSON key.
* what the door WRITES, from `Accounting.to_json()` itself, so the fix cannot
be "publish everything": the two sets must be equal.
## 4. A doorless bundle says why
Measured by PM (N5): built without `--accounting` there is no ledger, so
`asset_holds` falls back to its first route and a converted image is counted
claimed-and-not-found. That is the honest reading and it was a silent one --
the count was printed, its cause was not, and a reader of such a report can
only conclude the bundle lost the pictures.
**Chosen: say it out loud, not only in a docstring.** A docstring is read by
whoever edits the file; the reader who is misled is reading a REPORT. `_tally`
now names the missing ledger when, and only when, something was claimed and
not found -- two known-negatives hold that condition -- and `asset_holds` gets
the sentence as well, since it costs nothing. The gate itself always passes
the flag, so no row moves.
## 5. The count in a closing message
The previous closing message miscounted the outstanding work items. The count
here was measured at closing time against the queue itself, not from memory.
## 6. The bytes, and every gate
| what | result |
|---|---|
| R761 built from a pinned pre-change tree and from this one, shared inbox | `diff -r` **IDENTICAL**, **5 551** files |
| assets in that bundle | **50**, 29 JPEG + 21 PNG, **50 of 50** viewable |
| conversions booked, and lossless against Pillow | **19 of 19**, 2 366 365 pixels |
| soft hyphens | 71 removed, 0 in the bundle |
| content-accounting gate | `GATE RED: rows 2, 3, 6`, exit 1 -- row 2 8 of 13, row 3 17 of 22 (u = 19, d = 2), row 6 110 of 111. **Unchanged** |
| mutant runner | `killed 47 of 47`, exit 0 |
| suite, clean extract of the commit | see the closing message |
| `ruff check` / `ruff format --check` / `mypy --strict src/` | clean |
The BEFORE bundle was built from `git archive 23588e5` with `PYTHONPATH`
pointing at that tree, and the module path was printed in both runs, because
an editable install would otherwise have measured the working tree twice.
## 7. What this round did not measure
* The 43-document reference corpus. Unchanged since before the round and not
rebuilt (cost); the argument for it is the same as R761's, since the two
clauses can only fire inside an RLE8 BMP and 0 of that corpus's files are
one.
* Fidelity, which neither route of the judge proves. Unchanged.
* Whether another decoder besides Pillow draws the residual 32 the way this
reader does. One independent decoder is the measurement; it is not a vote.

# The retrieval gate had to resist the work it judges (2026-09-19)
PM's checkpoint on `2c8296b` ran eight cheating attacks at
`tools/okf_retrieval_gate.py` and **four went through**: rows 3, 5, 7 and 8
could each be taken GREEN without one label becoming true or one concept
ranking better. An eval written before the capability has one job beyond being
red today — it must not be closable by anything except the work — so the gate
was repaired before anything is built against it. `src/` is untouched, and
`git diff --stat` over it is empty for this whole round.
This report states what was closed, how each closure was measured, and the
three things it does NOT close.
## 1. The eight attacks, before and after
Each attack is a test now, named for PM's label, and the four that were
already refused stay as regression guards, so the table is 8 of 8 rather than
4 of 4.
| attack | before | after | where |

## 2. The row table, before and after
Nothing here became greener. Row 8 acquired a NUMBER, which is not the same
thing.
| row | before (`2c8296b`) | after | status |
|---|---|---|---|
| 1 | 9 of 9 GREEN | 10 of 10 GREEN | one fixture added (`set-quota.json`), one hit |
| 2 | 7 of 7 GREEN | 7 of 7 GREEN | unchanged |

| 6 | 9 of 9 GREEN | 10 of 10 GREEN | the same added fixture |
| 7 | 11 of 13 RED | 12 of 14 RED | `M14` added and felled; bar 12 of 13 -> 13 of 14 |
| 8 | 0 of 3 NOT RUN | 44 of 64 questions RED | measured against all three real sets |
| 9 | 0 of 6 RED | 0 of 6 RED | unchanged; it takes an input now |
`GATE RED: rows 3, 4, 5, 7, 8, 9` before and after, exit 1, byte-identical
over two runs.
## 3. Row 8 — the three sets, measured
Run once, on this machine, with all three sets read from their own
repositories by path + sha256. Nothing from them is committed here.
```
8 the real sets (three; one is a consumer's and is not restated) | RED
<consumer set>: figures withheld -- see the note below
r761-sk2: 7 of 7 fasit entries (concept) | 7 of 7 questions | sha256 c834a478e488
vegnormal-32: 31 of 43 fasit entries (concept) | 31 of 37 questions | sha256 c6d9305a0497
NOT SUMMED INTO ONE NUMBER: the citation-granularity set and the
concept-granularity sets are two numbers
```
34 misses, **33 of them class b** (below k with the quota off as well) and one
class c.
**Two of the three reproduce PM's recorded figures exactly**: wiki at 6 of 20
questions and r761 at 7 of 7. **The third does not, and the difference is
stated rather than smoothed.** PM recorded `32 of 43 citations = 21 of 32
questions`; this gate measures 31 of 43 and 31 of 37. The question counts are
not comparable at all: the gate splits a question citing two standards into
one Question per bundle, because a payload is built against one bundle, so 32
questions become 37. The citation count differs by ONE and that is a real
disagreement between two instruments over the same pinned bytes; it is not
resolved here and it is not this round's subject.
**The headline is at QUESTION granularity**, which is the fix for J2b: the
three sets share no unit — wiki names a citation, r761 a section title,
vegnormal a requirement number — and a citation hit plus a concept hit is a
number that is neither. A question is the one unit all three have. "Answered"
means at least one of its fasit entries arrived, the reading row 1 already
prints beside its own units.
## 4. What each closure rests on
**Row 8 requires all three sets by name** (`REQUIRED_REAL_SETS`) and is NOT
RUN otherwise — with the numbers the run DID measure still printed, because a
missing set must not cost the reader the set that was measured. This
repository's own test asserted `(1, 1, GREEN)` for a single set; that
assertion was the defect and it is corrected rather than worked around.
**Rows 2 and 3 take their denominator from the pinned set.** A forced fixture
that stops producing its declared class is a BROKEN PREMISE, printed as one
and counted against its row. At `k = 32` the three fixtures declaring class b
are delivered; before, they left the denominator and the rows read 4 of 4 and
2 of 2 GREEN.
**Row 3 carries a known-positive.** With `--source-quota` off every printed
reason is true — that is not a lie, it is an empty measurement — so a set may
declare `source_quota_in_force`, and the row is NOT RUN for it when the
default cut and the quota-off cut deliver the same concepts everywhere.
**The control's own premise was measured before it was built on, and it was
FALSE where it was first put.** Over the five existing sets the two cuts
deliver the SAME concepts — the quota is topped back up — so 52 labels move
`source_quota_exceeded` to `below_k` without one delivery changing.
`set-quota.json` is the one set where the quota genuinely decides: measured,
`oversikt-08` is delivered without the quota and withheld with it, and the
fasit `svar/broennproeve` is delivered only with it. The control survives the
honest fix, which changes labels and not the cut.
**Row 5 reads git for the half a registration cannot assert.** Three of its
ten checks: the file is committed and unmodified; the commit that ADDED it is
not itself a change to `src/llm_ingestion_okf/consume.py`; a change to that
path landed AFTER it. The third is the one that cannot be self-attested. What
git cannot prove is in the row's own docstring: history shows ORDER, never
that nobody read the number before writing the threshold.
**Row 7's roster is pinned apart from the list it names.** The bar is a share,
so a longer list is a lower bar per survivor. `MUTANT_ROSTER` and
`MUTANT_COUNT` are separate constants, duplicates are refused outright, and
the bar is taken from the roster's length.
**PM's G9 is decided: the term was observable and unobserved.** `hit =
bool(hit_ids) and bool(confirmed)` is reached only by a delivery that still
carries the citation and is no longer the concept file's bytes; every other
mutation of the text empties `hit_ids` one step earlier. `M14` is that
mutation, it is felled, and no production line changed.
**And that measures the judge's independence rather than asserting it.** PM
found the judge reads the bundle through `consume.delivered_text`, the same
function it judges. Measured both ways: with the index warmed BEFORE the patch
(which is what the gate does, and what row 7's docstring already relied on)
every unit comes back a miss with `confirmed False`; with the index built
UNDER the patch every unit comes back a hit. The gate never builds one under a
mutation. This is in `LIMITS` with the measurement, rather than closed by
re-implementing a normalisation rule this repository already owns once.
## 5. The mutation run
Twelve mutants of the gate plus one control that must survive, run in a
scratch copy of HEAD (`git archive` into `/tmp`, its own
`uv sync --frozen --extra extract --group dev`), each judged by
`tests/test_retrieval_gate.py`. The harness itself stays in the scratch copy:
it rewrites the gate file and restores it, which is not a thing to keep in a
tracked tree. What is recorded here is each mutant as a PROPERTY rather than
as a line of code, so the table does not go stale the first time the gate is
refactored.
| # | the guard it removes | felled by |
|---|---|---|
| X1 | row 8 counts whatever it was given, three sets or one | J2 |
| X2 | row 8's headline is the two granularities summed | J2b |
| X3 | row 2's denominator is the run's misses again | J10 |
| X4 | row 3 judges only what this run withheld | J10 |
| X5 | row 3 judges a run with no quota in force | J8 |
| X6 | row 5 believes the registration about its own history | J1 |
| X7 | row 5 accepts a registration no ranking change came after | the three-arm row-5 test |
| X8 | row 7 takes the mutant list as given | J3 |
| X9 | a delivery is a hit without checking the bundle's bytes (PM's G9) | the G9 test |
| X10 | the synthetic corpus is not pinned | the `SPECS_SHA256` refusal |
| X11 | row 9 ignores the set it was handed | the row-9 green test |
| X12 | a K2 set of any size wears K2's name | the size refusal |
| control | a detail line nobody asserts on is reworded | nothing — it MUST survive |
**First run: killed 11 of 12, and X2 SURVIVED.** Put row 8's headline back to
the sum and all 64 tests stayed green. The cause was the fixture, not the row:
three sets of one fasit entry each make "questions answered" and "units hit"
the same number, so the test agreed with the mutant by construction — the same
shape as round 158's X5. One set now carries two fasit entries, the only shape
where the two readings differ.
**Second run, on the commit that fixed it: killed 12 of 12, control survived.**
## 6. What this round does NOT close
- **Row 3 can still be made green by an honest change that costs elsewhere.**
Removing the quota makes every printed reason true; the price lands on row 1
(8 of 9) and on `M05`, which is felled. The gate is the unit, not the row.
- **The judge's parser is `consume`'s.** Bounded by measurement (§ 4) rather
than removed.
- **`SPECS_SHA256` is a digest of the corpus's fields, not of the bundle's
bytes.** `build_bundle` is deterministic, so the two move together; that is
an argument, not a measurement.
- **Rows 8 and 9 still cannot be green without inputs this repository must
not hold** — the three sets are on one machine and the K2 gold set exists
nowhere. Both are operator questions and both are open.
## 7. Denominators, re-measured against the sources
| source | measured here 2026-09-19 |
|---|---|
| a consumer's own set (read by path + sha256, never committed) | figures not restated here |
| `vegnormal-okf/docs/2026-09-10-sk2-r761-sporsmal.json` | sha `c834a478…`, 8 entries, 7 positives + KN |
| `vegnormal-okf/build/resonnering/sporsmal-m2.json` | sha `c6d9305a…`, 32 questions, 43 `must_cite` |
| K2 | 6 questions recorded; no gold set anywhere |

# Every carried image is one a model can be shown
`llm-ingestion-okf`, 2026-09-19. Raised from an internal measurement of the
frozen R761 package's `assets/` directory.
Nothing is tagged, pushed or released here. No new version: the entries go
under the untagged `[0.10.1]`.
## 1. The defect
`file` over the frozen R761 delivery's own `assets/`, denominator **50**:
| Format | Count | A model can show it |
|---|---|---|
| JPEG | 29 | yes |
| PNG | 2 | yes |
| PC bitmap, Windows 3.x, 8-bit, compression 1 (RLE8 BMP) | **19** | **no** |
The 19 are byte-correct files. They are also files nothing decodes, so 19 of
that document's figures were present and invisible at the same time — and the
concept's own `images: N` reported that they had arrived. An absence a reader
is shown is information; a picture that is there and unreadable is worse than
either, because the count says the opposite.
Reproduced here before anything was written, with the committed census
(§ 5): `19 of 50 CARRY image/bmp.bmp`, `29 of 50 CARRY image/jpeg.jpg`,
`2 of 50 CARRY image/png.png`.
## 2. The decoder: measured, then chosen
The order requires the choice to rest on a measurement of what the tree
already has. Pillow 12.3.0 is present, transitively under `pdfplumber` in the
`[extract]` extra, and `PIL` occurs 0 times in `src/`, `tests/` and `tools/`.
**It decodes RLE8 correctly.** A hand-written stdlib decoder and Pillow were
compared on all 19 real files, RGB per pixel through the palette: **19 of 19
identical**. So the measurement's answer is yes, and the choice is not made on
capability.
**Chosen: a stdlib reader. Why, and both reasons are properties of this
package rather than preferences.**
1. `read_image` is on the CORE path. `.html` and `.xml` are stdlib file types
that carry images with no `[extract]` extra installed, so a Pillow-based
converter either makes a core path depend on an optional binary wheel or
buys this package its second runtime dependency — against the "exactly one
runtime dependency, ever" rule a packaging test enforces.
2. An asset's name is its content digest, so the bytes the converter emits are
part of the bundle's identity. Encoding through an installed library would
make that identity move with the library's version. This is the property
0.10.0 felled page rasterisation over, stated in `encode_png`'s own
docstring, and it would be odd to defend it there and give it away here.
`encode_png` already writes a PNG from samples with `zlib` alone; this round
adds the reader in front of it. **Pillow keeps the job it is good for: the
INDEPENDENT decoder in the tests**, on neither side of the conversion.
## 3. What was built
- `assets.VIEWABLE_MEDIA_TYPES` — `image/png`, `image/jpeg`, `image/gif`,
`image/webp`. `read_image` tests every asset's SNIFFED type against it. It
is a property, not a list of formats we happened to meet. WebP is on the set
and `sniff` does not recognise one, so a WebP is refused one step earlier as
`asset_type_unknown`; the limit is stated rather than left implied.
- `assets.bmp_to_png` — 8-bit uncompressed, 8-bit RLE8, 24-bit uncompressed.
All five RLE8 opcodes: encoded run, absolute run with its pad byte, delta,
end-of-line, end-of-bitmap. Bottom-up unless the declared height is
negative. Palette read BGRA → RGB.
- Two published codes. `asset_not_viewable` — a real image in a format no
model can be shown, with no lossless conversion here (TIFF, JPEG 2000).
`asset_bmp_unsupported` — a BMP variant this reader does not express (RLE4,
BITFIELDS, 16/32-bit, BITMAPCOREHEADER, over 256 palette entries). Both
leave the concept's own "not carried" line and a row in the run log.
- `ExtractedImage.converted_from` and `.source_sha256`, written onto the
pointer's second line where the source's file name and pixel size already
live: original media type, original sha256 in full, new sha256 in full. Full
digests because the asset's file name carries only 12 hex characters of the
new one, and a checksum a reader cannot paste into `shasum -a 256` is
decoration.
**A converted asset is ONE asset.** One file in `assets/`, one pointer, one
row in the accounting — the accounting's own columns read
`ExtractedDocument.files`, which is what the resolver resolved, and conversion
does not touch it.
**The ceiling is paid before the pixels exist.** `bmp_to_png` bounds the
DECLARED size through the same `check_size` the rest of the image path uses,
before one row is allocated, and each RLE run is written as one CLIPPED slice.
Painting pixel by pixel would leave the memory bounded and the CPU unbounded:
a megabyte of `FF` runs is a hundred million paint steps against a 32-pixel
frame.
## 4. The eval, red first
Two red commits, because the mutant survey found holes in the first one.
| Commit | What |
|---|---|
| `fea0435` | 12 guards, 8 red on their claim |
| `9e99bb2` | 2 more guards the mutant survey found missing; 9 of 13 red |
The second commit is the interesting one. Walking the five mutants the order
names against the eval as committed, **two survived**:
- *"the format is read from the file extension instead of the bytes"* survived
because every image in the fixture was named after what it is: `.bmp` maps
to `image/bmp` either way. A BMP named `graphics/figur.png` can tell the two
apart.
- *"the ceiling is checked after decoding"* survived because the guard only
asserted that a refusal happens, and `encode_png`'s own `check_size` refuses
too — one frame later, after the memory is spent. The guard already measured
the peak; what it could not do was measure it affordably, since a
50 000 × 50 000 frame is 2.5 GB. At 7 000 × 7 000 the declaration is still
over the 40 MP bound and the unbounded frame is 49 MB.
**The lossless guard needed the same care.** Comparing "the carried asset that
holds these pixels" against the source is green before any conversion exists,
because a BMP carried verbatim trivially holds its own pixels. The holder has
to be required to be VIEWABLE; with that clause the guard reads `0 carried
assets hold these pixels` before, and passes after.
## 5. The measurements
**Lossless, on the real files.** Method: Pillow decodes the SOURCE BMP to RGB;
`read_image` converts it; Pillow decodes the RESULT; the two sizes and two RGB
buffers must be equal. Pillow is on neither side of the conversion.
- **19 of 19** lossless, 0 differing, **2 366 365 pixels** compared.
**Mutants, in a scratch copy of the tree.** Control green first, because
"killed N of N" can also mean the harness cannot invoke pytest at all.
| Mutant | Result |
|---|---|
| M1 the format is read from the file extension | KILLED |
| M2 the conversion skips 8-bit images | KILLED |
| M3 the palette is ignored (grey out) | KILLED |
| M4 the traceability field is omitted | KILLED |
| M5 the ceiling is checked after decoding | KILLED |
| M6 the BMP's BGR order is carried unswapped | KILLED |
| M7 the RLE delta opcode is ignored | KILLED |
**killed 7 of 7, survived 0, not measured 0**, control green at 13 passed.
**The census** (`tools/okf_asset_census.py`) is the committed instrument for
the known-positive. One row per image — the source's own sha256, the format
read off its bytes, and what `read_image` did with it — over every image file
and, with `--pdf`, every image object in every PDF it finds. Run from two
pinned trees and diff the rows.
It was itself caught by the rule it exists to serve. Its first version handed
`_pdf_images` a `page.page_obj` where the function reads `page.images` through
`getattr(..., [])`, so it reported **0 images over 67 PDFs** and exit 0 — a
clean-looking table that had measured nothing. The attribute is asserted now,
and the known-positive (one PDF, 8 images) is run before the sweep.
## 6. What the change costs, row by row
Two census runs over every image this machine holds — 18 403 files walked,
**67 PDFs opened, 9 714 image rows** — one from the tree before the
conversion and one after.
| Outcome | Before | After |
|---|---|---|
| `CARRY image/jpeg.jpg` (from PDF streams) | 3 053 | 3 053 |
| `CARRY image/jpeg.jpg` (standalone files) | 29 | 29 |
| `CARRY image/png.png` (from PDF streams) | 6 233 | 6 233 |
| `CARRY image/png.png` (standalone files) | 2 | 2 |
| `CARRY image/bmp.bmp` | **19** | 0 |
| `CARRY image/png.png in=image/bmp` | 0 | **19** |
| `CARRY image/jp2.jp2` | **16** | 0 |
| `REJECT asset_not_viewable` | 0 | **16** |
| `REJECT asset_pdf_unbounded` | 8 | 8 |
| `REJECT asset_pdf_unsupported` | 314 | 314 |
| `REJECT asset_samples_invalid` | 40 | 40 |
| **carried** | 9 352 | 9 336 |
**Exactly 35 of 9 714 rows moved**, and 9 679 are byte-identical — same
source digest, same carried digest, same origin. The known-positive is
stated on the rows rather than on the totals: **9 321 of 9 321** JPEG and PNG
rows are identical on both sides, so not one already-viewable picture changed
hands.
**The 16 are the finding this round did not go looking for.** JPEG 2000
objects, carried out of PDF streams by `JPXDecode`, in a format no model
decodes either. They were invisible before and are refused with a code and a
line now, which is the round's rule applied where it happens to bite. There
is no stdlib route to decoding JPEG 2000, so converting them is not
available: a consumer loses 16 pictures from a bundle and gains 16 statements
that a picture was there. That is the trade this round makes, stated rather
than buried in a total.
## 7. The accounting gate
The conversion broke the judge, and the judge caught it. `asset_holds` proved
a carry by hashing the SOURCE file and looking for those bytes in `assets/`;
a converted image's source bytes are not in the bundle. Measured on R761:
| | claimed and not found | row 6 |
|---|---|---|
| with the conversion, before the judge's second route | **19** | 90 of 111 |
| after | **0** | 110 of 111 |
19 is exactly R761's RLE8 count. The judge now also reads the two digests the
bundle states on the pointer line and then hashes the asset itself, so a
bundle claiming a conversion it did not perform still fails — three cases in
one test, one positive and two negative.
The gate's verdict is unchanged: **`GATE RED: rows 2, 3, 6`**, the same rows
STATE recorded before the round, with row 3's numbers (u = 19 unaccounted,
d = 2 double-booked, 17 of 22) identical across both runs — they are the
reference corpus's own losses, which the operator left standing red on
2026-09-17. R761 reads exit 0, 1 of 1 persisted, **50 asset files, 31 081
carried elements found, 0 claimed and not found**.
## 8. What this round does NOT do
- **JPEG 2000 is refused, not converted.** No stdlib route exists.
- **WebP is not sniffed**, so the viewable set's fourth member is unreachable
today. The set states what a model can be shown, not what this package
reads.
- **`.xlsx` still carries no image** — a pointer block inside a sheet's pipe
table would break the `source_rows` locator, unchanged from 0.10.0.
- **Nothing is tagged, pushed or released.** The CHANGELOG entries go under
the untagged `[0.10.1]`.
- The reference corpus is **not rebuilt**. The exposure is measured per image
by the census, which is the finer instrument for this change: a rebuild
reports that bytes moved, the census reports which image moved and why.

# The pointer block, bound to the run
2026-09-19. PM's checkpoint on `ae441ab` judged the previous round PARTIAL
with one load-bearing rest and two small ones. The rest is the same class the
round before it: the judge's fasit came from the reader it judges. It had been
narrowed, not closed. This closes it, closes the two small ones, and clears
three further residuals PM had listed. No new format, no new dependency, no
version bump and no tag.
## 1. A form is not a signature
`tools/okf_accounting_gate.py` read the conversion claim out of the bundle
text. The round before bound it to a POINTER BLOCK, which is the two lines
`assets.render_block` writes:
```
![<label>](/assets/<sha12>-<name>)
Image: <name> (<w>x<h> px) -- converted from <type> sha256:<A> to <type> sha256:<B>
```
That closed the two routes PM had measured (an `alt` attribute and plain body
text) and left the class open, because a document can write the whole block.
Reproduced here through the real `okf build`, three ways, each a whole build:
| way | before | known-positive in the same build |
|---|---|---|
| two `<p>` elements in one HTML file | **forged** | held |
| one `<p>` with a `<br>` | **forged** | held |
| a markdown note beside the HTML carrier | **forged** | held |
"Forged" means `asset_holds` returned True for a BMP declaring 50 000 x
50 000, refused `asset_too_large`, absent from `assets/`. The forger needs two
digests: the one it wants vouched for, and one of a picture the bundle really
carries — public in the bundle, and computable in advance for a PNG carried
verbatim.
### What was chosen, and why
Two fixes were on the table. The claim is now read from the RUN's own ledger:
- `assets.conversion(image)` names the `(source digest, asset digest)` pair.
- `DocumentAssets.conversions` carries it out of the run.
- `DocumentAccount.conversions` books it, and `okf build --accounting` writes
`conversions: [{from, to}]` per document.
- `_declared_conversions` reads that file; `_conversions` believes a pair only
when the ledger holds it AND a pointer block confirms it for the asset it
points at.
The confirmation can be forged and the ledger cannot, which is why the ledger
decides. The alternative — neutralising pointer-shaped text at extraction, the
way the soft-hyphen door neutralises U+00AD — was felled: it changes what every
document SAYS in order to defend a tool outside the build, a source quoting a
bundle listing would come out altered, and the bytes of existing bundles would
move. This reads a file the run already writes.
A build with no accounting door has no ledger. A converted image is then
reported claimed-and-not-found rather than believed, which is the reading the
gate had before the conversion route existed, and it is visible in the row.
### After
3 of 3 forged → refused, with the known-positive True in all three. The
text-level regression guard goes from 3 arms to 13: PM's eleven ways that the
shape anchoring already refused, kept so a later narrowing cannot widen one of
them, plus the two forms that defeated it — a perfectly written pointer block
the run never booked.
R761 rebuilt from the frozen delivery: bundle `diff -r`-identical to the build
before the change, 50 assets (29 JPEG + 21 PNG, 0 BMP), 19 of 19 conversions
confirmed against 19 declared, soft hyphens 71 → 0, u = 0, d = 0, exit 0.
## 2. A terminator is not a coverage proof
The previous round's terminator rule asks only that a stream SAY it is
finished, and a stream may say so anywhere. Measured: a stream whose FIRST two
bytes are the end-of-bitmap escape was carried, with 32 of 32 pixels never
decoded and all of them palette index 0. Pillow refuses the same file.
`_bmp_rle8_rows` now also requires the cursor to stand at or past the end of
the last row, refusing with the same `asset_samples_invalid` otherwise.
**The line is the cursor, not the pixels.** A delta escape and an end-of-line
escape STATE their skip, so the pixels they pass over keep index 0 and every
decoder produces the same picture; a pixel-coverage count would refuse both
constructions the format defines. The corpus cannot choose between the two
rules — over the 25 RLE8 BMPs the R761 delivery ships (24 distinct; the bundle
carries 19), 25 of 25 paint every pixel, 25 of 25 reach the end of the frame
and 0 of 25 use a delta. An independent decoder can:
| stream over one 8x4 frame | cursor reaches the frame | Pillow |
|---|---|---|
| end-of-bitmap before one pixel is decoded | no | refuses |
| one 4-pixel run, then end-of-bitmap | no | refuses |
| last row one pixel short, no end-of-line | no | refuses |
| every row painted and closed | yes | reads |
| last row one pixel short, then end-of-line | yes | reads |
| a delta skipping a whole row | yes | reads |
| last row painted to its end, no end-of-line | yes | reads |
| the shipped fixture, which uses a delta | yes | reads |
Eight of eight agree with the new rule, and a second test holds Pillow to the
table so it is not our own rule restated.
Both docstrings PM named are rewritten. The test no longer says "NO PIXEL MAY
BE GUESSED: either every one of them is decoded from the stream, or the picture
is refused" — that was false as measured. `_bmp_rle8_rows` no longer frames the
delta argument as read off the corpus, which it never was: 0 of the 25 files
use a delta, so the corpus had nothing to say about it.
## 3. One number, read from one place
`assert sum(tbx.values()) == 568` sat behind a `skipif` on a delivery only this
machine has, so on a fresh clone the sentence five files publish was unguarded
again — the state in which 574 survived in four docstrings until PM counted it.
`N101_TBX_TAGS` is now the one place the number lives, and a second test reads
the published sentence out of `CHANGELOG.md`, `CLAUDE.md`, `tools/okf_witness.py`,
`tests/test_accounting_gate.py` and this round's predecessor report, holding all
five to it. It needs no corpus and no clock.
It was red at birth, and for a reason worth keeping: the scan read the test
file's own known-positive string (`574`) as a sixth publisher. That string is
now assembled from pieces, and the failure is the demonstration that the scan
reads what it is pointed at. What the guard does NOT prove is stated in its
docstring: five files agreeing is agreement, not a count. The measurement stays
where it was.
## 4. A clean extract is not a checkout
`test_the_four_existing_goldens_are_untouched` ran `git status` with
`check=True` in a `git archive` extract and raised `CalledProcessError`. It was
the single failure of the whole suite run from a clean extract, twice reported
as a round's one failure by a round that had not touched the file. Both arms
measure the checkout with `git`, so an extract has nothing to ask: it now skips
with the reason stated, and a checkout still has to answer.
## 5. The mutant runner
`tools/okf_gate_mutants.py` could only run one test file, which is why PM's
three survivors from `43331fc` could not be added: two are held by the gate's
row 3 and one by the soft-hyphen door's own suite. A mutant now names the suite
it is judged by, and the catalogue goes 39 to 45:
- **X3** and **X4** were rewritten against the code as it now stands. A mutant
table is a copy of the code it mutates, and this round moved the lines both
of them quoted.
- **X6** is the defeated state exactly: a pointer block believed without the
run having booked it.
- **X7** cuts the ledger off at its source.
- **X8** removes the cursor rule.
- **P6**, **P11**, **P12** are PM's three, now held by what runs AS the gate.
Two survivors appeared on the first run and both were findings.
**X4** — "the claim need not be about the asset its block points at" — survived
because every forgery arm now fails on the ledger check before the binding is
reached. An arm was added where the run DID book the pair and the block stating
it points at another picture; under the mutant that reads as a carry.
**X5** — "a document-supplied label may emit a checksum field" — survived the
WHOLE suite, measured: 2134 passed with the disarming removed. The gate no
longer reads its claim out of the bundle, so a document-supplied field cannot
reach it. The property did not stop mattering — the line stands in every
concept body, and a bundle must not state a conversion in a sentence the run
did not write — so it is measured where it lives, in `tests/test_assets.py`,
and the mutant is judged there. Deleting an unfellable guard was the other
option and was felled: this guard is about the bundle, not about one judge.
## 6. What this round does not do
- It does not teach the gate FIDELITY. A converter writing a blank PNG is still
accepted, for the reason `asset_holds` states: both routes ask whether a file
holds the bytes the run names, and neither decodes a pixel.
- It does not touch the guard, the goldens, the proposer, any profile, any
version or any dependency.

# The accounting gate's remainder, and one normalisation door
`llm-ingestion-okf`, 2026-09-19. Raised
from a re-measurement of `ed8d9d7`
(verdict: PARTIAL). Six holes, each with a red test written in its own commit,
plus the operator's decision of 2026-09-18 about U+00AD.
Nothing is tagged, pushed or released here.
## 1. What the round closes
| # | Hole | Closed by | Red first |
|---|---|---|---|
| H1 | a partly refused corpus is "clean" | `Unit.refused` + `Accounting.refused` | `5d1060d` -> `d27ca50` |
| H2 | one of B-1's six refusals held by no test | mutant X2 + a two-sided test | `a59898e` -> `a94b0c5` |
| H3 | `math`/`figure_caption` do not fire on a real delivery | `_local` on the JSON tag + a `figcaption` clause | `37599a3` -> `d31ab73` |
| H4 | the mutation harness is not a gate | `verdict(survived, errors)` | `6abe4b4` -> `f5b263f` |
| H5 | the skipped-row guard is unreachable | it measures the DEFAULT sources | `253c4fb` -> `8b4f409` |
| H6 | N200 contributes one blank red | `measures_no_class` in row 6 | `e6d9f16` -> `280d6bd` |
| — | R761 refused whole over 71 soft hyphens | `extract.normalise_extracted` | `68cfa90` -> `eebaf53` |
## 2. The normalisation door (operator decision 2026-09-18)
`llm-ingestion-guard` 1.4.0 keeps U+00AD in `_ZERO_WIDTH_CPS` beside U+200B,
U+200C, U+200D and U+FEFF, and `output:zero-width-present` is an **any-tier
carrier**: `fail_secure` at every trust level, with no sanitisation and no
exception. R761 Prosesskoden:2025 carries **71 U+00AD and 0** of the four real
zero-width characters (U+2060 also 0). All 71 are Norwegian hyphenation points
inside words -- `ar[SHY]beider`, `bitu[SHY]men`, `asfalt[SHY]betong` -- so a
701-page process code was unreadable for the whole chain over typography. The
verdict was formally right and materially a false positive.
Of the three ways out, the operator chose one door in okf, before the guard,
that removes the character and BOOKS the number. The other two were felled:
weakening the guard's rule is the security repository's call and takes a screen
away from every consumer; delivering a cleaned corpus fixes one document and no
other.
**Where it is.** `extract.normalise_extracted(text) -> (text, removed)`, applied
once at the end of `extract_document`, so both entry points and both sides of a
plan's `text_sha256` see one string. `_pdf_units` measures its page offsets
through the same door: that table is CHARACTER offsets rebuilt from the pages
while the text it indexes comes back normalised, and a table built against the
other rendering names the wrong page with full confidence. Removing a character
removes no newline, so every line-indexed rule downstream -- the proposer's
grammars, `xml_outline`, `pdf_outline`'s per-page line check -- is unmoved by
construction.
**What it says.** `ExtractedDocument.soft_hyphens` carries the count out,
`InboxResult.normalised` carries it per document, and `account_run` reads it off
the RUN rather than recounting the source -- a second count would be a second
reader. It reaches the accounting JSON as `normalised_soft_hyphen` at both
levels and `log.md` as a `**Normalisation**` bullet.
**What it does not touch.** The guard. The other four characters -- they carry
no typographic job in running text, so removing one would be a decision about
what the guard screens for, taken in the wrong repository. U+00A0 NBSP, which
is not in the guard's set at all (6 633 of them in R761).
**Measured, on R761's own delivery, through the DEFAULT gate:**
```
exit 0, wall 25.2 s
run normalised_soft_hyphen: 71
refused: 0 unaccounted: 0 double_booked: 0
doc 14ce59dc-....xml status persisted normalised_soft_hyphen 71
LOG: * **Accounting**: 1 document(s) and 109 other file(s); 31096 elements
found in the sources; 0 unaccounted, 0 double-booked; 0 of 1 document(s)
refused whole.
LOG: * **Normalisation**: 71 soft hyphen(s) (U+00AD) removed from 1 of 1
document(s) before the persist gate. No other character is touched.
```
**Reach, measured rather than argued.** 0 of the **78** readable documents of
the K2 reference corpus carry U+00AD or any of the five other characters (the 8
unreadable ones raise before extraction, so the denominator is 78 of 86); 0 in
the pinned K2 bundle's concept bodies; U+00AD is 0 of the **230** readable
tracked files across `tests/fixtures`, `examples`, `skills`, `docs`, `src`,
README and CHANGELOG. The door cannot have moved a byte anyone here has
measured.
**Corrected 2026-09-19.** That last clause first read "0 across" for all SIX
characters, and that is false: **2 of the 230** carry U+200B --
`tests/fixtures/accounting/rejected/avvist.html` and its inventory twin, this
repo's own known-negative for a carrier the door refuses to remove. For
U+00AD, the character the door actually removes, the figure is 0, and that is
the one the reach argument needs.
**Known-negative, in the suite.** A source carrying U+200B is still
`fail_secure`, still exits 1, and the character is still in the extracted text.
Text preservation is stated as an EXACT invariant and never a share: the
extracted text of the hyphenated source EQUALS the extracted text of the same
source written without the hyphens.
## 3. H1 -- a document refused whole is never clean
A refused document books every element as a coded rejection, so `u = 0` and
`d = 0` and the unit balances by construction; `refused_whole` asks its question
only for a corpus that persisted NOTHING. PM measured the ordinary case: one
refused source beside one accepted one gave `clean = 4 of 4`,
`refused_whole = None`, `okf build` exit 0 and three elements gone unseen.
`Unit.refused` is a fifth column and the only one that is not a defect in the
report. Row 3's reason carries `N element(s) lost with R of D document(s)
refused whole`, and each unclean unit's detail line carries `refused=` with the
document's own rejection code in the note.
On the build side, `Accounting.refused` goes into the JSON and into `log.md`.
**The exit code does not move**: it belongs to the whole run, and a corpus
holding one unreadable file among many is ordinary. The order allowed either,
and this is the half that does not break every build that passes today.
`test_a_corpus_refused_whole_under_the_default_gate_is_red` kept its point and
lost its premise: it now asserts `u = 0` and `d = 0` rather than a clean unit.
## 4. H3 -- the role map reads the publisher's own tags
Two independent causes, one line each.
- `count_sts_xml` takes every tag through `_local`, which strips a
Clark-notation namespace AND a prefix. `count_sts_json` compared the raw
string, so `mml:math` reached `tag == "math"` on nothing: **74** formulas in
N200, 2 811 characters, counted as 0.
- The publisher's JSON writes a figure's caption as `figcaption` under the
`graphic`, not as the `fig/caption` NISO-STS writes: **49** in N200, counted
as 0.
The `figcaption` clause is in the JSON map ALONE. The two maps are written twice
on purpose so row 5 can see a hole in either, and the XML delivery has never
been measured carrying one.
**No other count moves**, measured role by role over the eight JSON deliveries
on this machine and the three committed twins:
| delivery | before -> after |
|---|---|
| N100-2022 | `figure_caption` 0 -> 123 |
| N100-2023 | `figure_caption` 0 -> 127 |
| N101-2025 | `figure_caption` 0 -> 62 |
| N200-2024 | `figure_caption` 0 -> 49, `math` 0 -> 74 |
| N303-2026 | `figure_caption` 0 -> 43, `math` 0 -> 3 |
| N500-2024 | `figure_caption` 0 -> 27, `math` 0 -> 88 |
| N601-2022 | no change |
| R761-2025 | no change (row 5's pair) |
| the two existing twins | no change |
The known-negative for stripping a prefix is N101's **568 `tbx:`** tags: not one
of their local names is a role here, and it is in the suite.
## 5. H2, H4, H5, H6
**H2.** PM's X2 mutant -- delete the refusal of a report that declares a
document `rejected` while the bundle holds a concept from it -- is now in
`tools/okf_gate_mutants.py`. Reproduced before the test: **98 passed, rc 0**,
the pattern applied exactly once. The test drives it from both sides, so a gate
refusing EVERY rejected document would not pass either.
**H4.** `verdict(survived, errors)`: 2 when a mutant could not be applied (it
was never measured, and that outranks everything), 1 when one survived, 0
otherwise. The run ended `2 if errors else 0`, so `killed 0 of 1` was an exit 0.
**The harness caught this round's own change.** Its first run reported
`killed 34 of 35` and `ERROR: M21 ... pattern occurs 0 times -- NOT MEASURED`:
H1 had rewritten the `clean` property M21 mutates. M21 is repaired, and X3 --
"a document refused whole is clean again" -- is added beside it, because M21
removes `unverified`, `invalid` AND `refused` at once and would be killed by
any one of the three. Final run: **killed 36 of 36, 0 survived, 0 errors, exit
0**.
**H5.** The skipped-row guard measures `real_corpora(R761_DEFAULT,
N200_DEFAULT)`. Row 6 is SKIPPED exactly when the corpora the ARGUMENTS name are
absent, so asking the arguments made the branch unreachable. Two tests, so a
guard that fires on everything fails too: with the default source present and
the arguments pointing elsewhere the run exits 1 and names the row; with no
corpus on the machine it exits 0.
**H6.** `measures_no_class(units)` returns a sentence when EVERY document of a
corpus has no declared fate, and row 6 prints it beside that corpus's tally.
Reproduced 2026-09-19: `okf build` on N200 proposes 0 plans, prints `FAILED - no
segmentation plans` and exits 2 BEFORE the accounting door -- **no accounting
file is written at all**. What it would take is a capability and not a
threshold: `.json` is read as generic JSON, and the publisher's STS delivery in
that form would have to reach the markdown grammar `_extract_xml` writes for the
XML one. `standardContent` occurs **0** times in `src/` and 4 in the witness,
with the query validated against that known positive.
## 6. The gate, after
`python3 tools/okf_accounting_gate.py` -> **exit 1, `GATE RED: rows 2, 3, 6`**.
| row | k of M | status | moved this round |
|---|---|---|---|
| 1 file types with a fasit fixture | 13 of 13 | GREEN | no |
| 2 source inventory before build | 8 of 13 | RED | no |
| 3 accounting after build | 17 of 22 | RED | no |
| 4 a rejected document is reported honestly | 1 of 1 | GREEN | no |
| 5 two witnesses agree | 4 of 4 | GREEN | no |
| 6 real corpora | 110 of 111 | RED | **the reason did** |
Rows 2 and 3 are the reference corpus's own losses, which the operator decided
on 2026-09-17 stay red until they are fixed.
Row 6 keeps its count and changes its cause. **R761 now passes the DEFAULT
gate**: `exit 0, 1 of 1 document(s) persisted, 50 asset file(s); 31 081 carried
element(s) found in the bundle, 0 claimed and not found`, `u = 0, d = 0` under
both gates. The only `refused whole` left is N200, and that is the build exiting
2 on 0 plans -- H6's blank, now stated in the row.
## 7. Limits of this round
- **Rows 2 and 3 are untouched.** Nothing here fixes a loss in the reference
corpus; the round closes the instrument's holes and one refusal.
- **The 43-document reference corpus was not rebuilt.** The exposure argument
for the normalisation door is a census over the corpus's extracted text (0 of
78) and over the pinned bundle's bytes (0), not a rebuild.
- **Red first is per commit and per hole, not per assertion.** H2's red is the
mutant surviving, not a failing test: the check it protects already worked,
and a test for working code cannot be red.
- **`test_r761s_own_seventy_one_soft_hyphens...` skips** where the corpus is
absent. The committed twin fixture is what holds the rule elsewhere.
- **The witness is still a second implementation of the same definitions.**
A definition wrong for a format is wrong on both sides at once, and the gate
says so in its own output.

# An MCP surface over OKF bundles, in two shapes
2026-09-20. Capability loop:
the eval was written RED at `5f1772e`, before any server existed; the capability
follows in its own commit.
The operator's question was not "does MCP work". It was: one server per bundle
or one server for many, and **must these artefacts be made again every time a
bundle is rebuilt or a new one appears?** This round builds the three artefacts
that question compares, and measures the answer.
## What was measured, and against what
`tools/okf_mcp_gate.py`, six rows, one exit code. The server is started as a
subprocess and spoken to over newline-delimited JSON-RPC beginning at
`initialize` -- never imported. A client built from the server's own framing
helpers would agree with the server by construction, so the client is written
separately in the gate.
Denominators are pinned in the gate and recounted a second time in the tests:
7 required tools across the two shapes, 4 artefact classes, 3 bundles times 3
discovery checks, 3 cross-bundle checks, 6 hostile cases. A row that counted
what the server happened to offer would go green by offering less.
| row | what it asks | today |
|---|---|---|
| 1 | every required tool answers over real stdio, carrying bundle id and concept id | **7 of 7** |
| 2 | every anchor the frozen graded set points at, fetched verbatim | **83 of 181** |
| 3 | one concept changes: does the stale artefact refuse, or answer quietly | **4 of 4** |
| 4 | three unknown bundles appear while the server runs | **9 of 9** |
| 5 | one documented sequence, two bundles, both sources | **3 of 3** |
| 6 | traversal, symlink, broken manifest, 10 MB concept, unknown id | **6 of 6** |
`GATE RED: rows 2`, exit 1.
Reproduce:
```sh
uv run python tools/okf_mcp_gate.py \
--sett <the frozen set>/sporsmal.json \
--frys <the frozen set>/frys.json \
--bundle-root <a directory holding its bundles>
```
Without the last three flags row 2 is `0 of 0` with the reason stated: the set
names a consumer's documents, this repository is public, and a gold set is an
input here and never a constant.
## Row 3 is the operator's question, and the answer has four rows
The drill: copy a bundle, start the artefact, change one concept, ask again.
| artefact | stale answer | artefacts to remake | manual steps |
|---|---|---|---|
| one server in front of one bundle | refuses / cannot go stale | 0 | 0 |
| one server in front of many | refuses / cannot go stale | 0 | 0 |
| today's generated skill (per bundle) | refuses out loud (`bundle_mismatch`) | 1 | 1, **per consuming project** |
| the generic skill (one for all) | cannot go stale | 0 | 0 |
**Neither MCP shape needs an update when a bundle is rebuilt, and neither needs
one when a bundle is added.** That is not luck: nothing is cached across calls.
Every call re-walks the roots and recomputes the bundle's content identity, so
the identity in an answer is a fact about the bytes at the moment of the call.
The cost is real and is paid per call -- see the limits below.
Row 3 was **1 of 4 before any capability existed**, which the order did not
predict and is worth stating: today's per-bundle skill already refuses out loud
when its bundle moves, because `okf check`'s `bundle_mismatch` rule compares the
declared ref against the payload's. The skill's cost is not silence. It is that
one artefact has to be regenerated and reinstalled wherever it was installed,
and that number is not measurable from inside this machine.
## The generic skill, measured rather than assumed
The order cited 227 of 285 lines identical between two generated skills,
measured 2026-09-18. Measured again here, on two different bundles
(`examples/ingest-golden-segmented-okf-v0-2` and `tests/fixtures/consume-bundle`):
**281 of 313 and 311 lines identical, 62 lines differing**
(re-measured 2026-09-20 after the breaking-point sentence was repaired; it was
280 of 312 and 310, with the same 62). Neither number
contradicts the other -- they are different pairs of bundles -- and the shape of
the finding is the same: what differs is identity, concept count, the
conditional-field table, the whole-bundle cost and the breaking point.
`skill.render_generic()` carries none of them. The property that makes that
claim checkable rather than asserted is that **the function takes no argument**:
there is no bundle it could have read, and two calls return the same bytes. A
test controls it against a per-bundle skill, which must carry exactly what the
generic one does not -- without that control, an assertion about an absence
passes on an empty string.
The per-bundle half is `okf card <bundle>`, **derived on every run and never
written into the bundle**. The order proposed storing it there. Writing a card
file into every bundle would move the bytes of all six `examples/*/expected-bundle`
trees (23 files compared byte-for-byte) and of the pinned reference bundle, to
store something recomputable in under a second -- and a stored card is one more
artefact that can disagree with the bytes beside it, which is the defect the
generic skill exists to remove. Chosen as derived because it answers the
maintenance question more completely, not less.
## Row 2 decomposed: the bundle, the ranker, and the vocabulary
**83 of 181** (bundle, anchor) pairs, `M = 181` counted from the set at run time.
The order's own figure of 197 is the set's atom count under a different
definition; 181 is what the pair rule below yields on the file as frozen at
version 4.
Three numbers, and the middle one is the finding:
* **99 of 181 pairs are present in the bundles at all.** 82 are not: the text
the set quotes is not in the bundle, which is red for the BUNDLE and not for
the server. `r761-2025` is the sharpest case at 17 of 33 present.
* **83 of the 99 present were reached**, so the surface reaches 83.8 % of what
is there. `r761-2025` is again the outlier: 2 reached of 17 present.
* **0 of 83 were met by `okf_fetch` on the anchor as a concept id.** The set's
anchors (`Krav 2.3.1—3`) and this library's concept ids are different
vocabularies, so the cheap route -- a true ceiling -- never fires, and every
pair met was met through `okf_ask`, which runs the ranker. **That makes 83 a
FLOOR on the ceiling, never the ceiling.** A surface offering a lookup by the
publisher's own anchor would separate the two, and does not exist today.
Quote comparison folds exactly two things and nothing else: U+00AD, because
`okf build` strips soft hyphens from extracted text while the publisher's JSON
keeps them, and whitespace runs, because a quote cut out of a paragraph carries
the line breaks of wherever it was cut. Case is not folded.
## Hostile input, and why a code set rather than "was refused"
Row 6 declares, per case, the refusal CODES that count as the right refusal.
The first run of this gate had the 10 MB concept refused as `concept_unknown` --
the fixture had written the file without naming it in the index, so the size
ceiling never ran and the row was green for a reason unrelated to the attack.
Two checks giving the same verdict are not the same guarantee.
Containment is two independent checks: the bundle's own index must name the
concept, AND the resolved path must be inside the bundle. A mutant removing the
first one **survives**, and the mechanism is printed: the traversal is then
refused by the second, as `path_escape` instead of `concept_unknown`. A mutant
removing both is killed. That survival is the redundancy working and is reported
as such rather than as a kill.
**A note added 2026-09-20, after this round:** that sentence was true of
`okf_fetch` and of no other tool. `okf_ask` and `okf_describe` made only the
first of the two checks -- the index rule, which is a string rule and cannot
see a symlink -- and read whatever the joined path pointed at. The second check
now lives in `consume.resolve_in_bundle` and every reader here goes through it;
the tests are `tests/test_read_path_containment.py`, red on 8 of 11 rows before
the repair with `okf_fetch`'s two rows green as the control.
## Mutants
13 mutants, applied in a scratch copy of the tree and never in the working tree,
with an unmutated control first: **12 killed, 1 survived with a mechanism, 0
errors.** The control's gate rows and pytest targets are green before the first
mutation, so a kill cannot be the call having failed.
Killed: a cached bundle identity (row 3), two bundles known by name in the
many-shape (row 4), a fetched concept without its concept id (row 1), both
containment checks removed (row 6), discovery run once at startup (row 4), row
2's denominator taken from the run (test), a symlink descended (test), the size
ceiling removed (row 6), the generic skill naming a bundle (test), a broken
manifest skipped silently (row 6), a listing tool on the one-shape (test), and
an unknown bundle answered instead of refused (row 6).
## Limits, stated rather than implied
* **Nothing is cached, and it costs.** On the 2 756-concept bundle the content
identity is a 0.75 s hash of the whole concept tree and one `okf_ask` is
5.6 s. Row 2's full run over four bundles and 181 pairs took **4 min 13 s**.
A cache would have to be keyed on something cheaper than the hash and still
correct; no such key is shipped, and the cost is the price of the row-3 result
above.
* **The gate measures a ceiling and a maintenance cost.** Whether an arm answers
WELL is a different question, asked by `tools/okf_retrieval_gate.py`. No arm
was run here and no model was called.
* **The architecture choice is the operator's.** These rows are its input.
* Row 3 counts artefacts and steps inside this machine. A project that has
installed a generated skill pays one more step per project, and that number is
not measurable from here.

1. The pre-pass MUST do the reading, the ranking and the cut. The skill MUST do
the judgement.
2. The skill MUST NOT read the bundle outside what the payload delivers or
explicitly names as reachable. **The payload names the best-ranked withheld
concepts (§ 5.3), and those are reachable**: running the pre-pass again with
other terms, or fetching a named concept, is another measurement under the
same rules, not a way around the first one. What stays forbidden is § 9's
two: enumerating a directory the profile does not declare derived, and
reaching the verdict layer.
This clause said "context the pre-pass withheld was withheld deliberately"
until 2026-09-20, which a skill reasonably read as "one run per question".
Measured on a large real bundle, the first run's cut is one ranking's
answer to one wording, and no wording of the operator's question put the
right document inside the cut — so a rule against a second run is a rule
against finding it at all. The `withheld` block exists in the shape it does
so that a second run can be aimed rather than guessed.
explicitly names as reachable. Context the pre-pass withheld was withheld
deliberately.
3. The skill MUST declare the cut in its output rather than reporting as though
it had read the bundle. An undeclared cut is a denominator failure (§ 5)
dressed as an answer.
4. A conformant skill MAY be handed a payload by any transport. The transport is
not part of this contract.
### 2.5 Working method
A conformant skill MUST state a **working method** — how a question becomes
searches — and MUST NOT state one that stops at a single run.
1. It MUST tell its reader to read the bundle's own map before searching, and
to put the question into the bundle's terms. A bundle in one language and a
question in another share few tokens, and a pre-pass matching tokens then
ranks on almost nothing.
2. It MUST tell its reader to split a broad question into sub-questions written
in the bundle's own terms, and to give every sub-question to the pre-pass —
in ONE run where the pre-pass takes several (§ 8.9), otherwise one run each.
3. It MUST say that several runs are permitted and expected, and MUST NOT
contain a sentence forbidding a second run with other terms. Both the
`withheld` near misses (§ 5.3) and § 2.2 exist so that the second run can
be aimed.
4. Where more than one bundle is in scope, it MUST tell its reader to run the
same sub-questions against each — in ONE run over the folder that holds
them where the pre-pass takes a folder (§ 8.11) — and to keep each piece of
material attributed to its bundle.
5. It MUST tell its reader to assemble ONE answer — ordered by sub-question,
stating which source holds where sources disagree and with which version,
and saying what the bundle does not cover.
### 2.6 Answer form
A conformant skill MUST state an **answer form**, and that form MUST put the
answer before the audit trail.
1. The answer is written in the questioner's language, whatever language the
bundle is in, in ordinary prose.
2. The instrument's vocabulary stays out of it: withholding-rule names,
digests, budget lines and the word *denominator* describe how the answer
was produced, not what it says.
3. Source references are short and of the kind a textbook gives — the document
and the section, plus the bundle where more than one was read.
4. The audit trail of § 3, § 5 and § 7 — the markings, the three counts, the
ref, the rules the declined concepts fell under — is written when the
questioner asks for it, or into an artefact that will travel without the
skill (§ 8's document mode), and otherwise MAY be omitted from the answer.
The obligation to HOLD a marking and a source for every claim is unchanged:
what this clause governs is what the reader is made to read.

SPEC § 6.1, "Consumers MUST tolerate broken links". A `parent` names that one concept as reachable
in § 2.2's sense and names nothing else. The checker refuses
(`parent_unfollowable`) a `parent` that is not both members, that names its
own excerpt, or — **only where `withheld.complete` is true** — whose
`concept_id` is in neither `excerpts` nor `withheld.nearest`. Together those
name every concept the pre-pass considered (§ 5.2), so a pointer outside
them names nothing in the bundle; over a payload that named a sample of its
drops they do not, and a checker applying the clause anyway would refuse
correct pointers at the rate the sample is short. That the clause did not
run is a fact about the payload's shape, stated here rather than left as a
silence. A pre-pass MAY also carry
own excerpt, or whose `concept_id` is in neither `excerpts` nor `withheld` —
together those name every concept the pre-pass considered (§ 5.2), so a
pointer outside them names nothing in the bundle. A pre-pass MAY also carry
the enclosing concept's text inside `parent` — `text`, with that concept's
own `sha256`, and `truncated` where it was cut to fit — and then only from
the room its cut left, so that inherited text never displaces an excerpt.
7. A pre-pass SHOULD carry `coverage`: the terms it read the question as, the
ones no concept in the bundle answers, and the ones no delivered excerpt
answers. Without it a reader holding eight excerpts cannot tell a bundle
that answered its question from one that merely ranked something — the two
payloads have the same shape — and § 6's states are then unreachable from
the payload alone.
**Facts, and no verdict.** The member carries lists and never a score, a
confidence or a "weak" flag, because the two obvious verdicts were built
and falsified against 81 questions on 2026-09-20: the share of a question's
terms a delivered excerpt answers separates a synthetic corpus at 0.33
against 0.50 and then reverses on real data, where covered questions run
down to 0.27 while one genuinely uncovered question sits at 0.71; and the
share of a bundle tying the best lexical match is ~0.00 for every question
in a large bundle, covered or not. Question style dominates the first and
corpus size the second, so a pre-pass emitting a verdict would assert
across corpora what was measured on one. Where a bar belongs is in the
consumer's own judgement or in a gate that publishes its sweep.
**One reading is carried, with its rule in the open (v1.1).** `absent_terms`
lists the question's words the bundle holds in NO form — not as written, and
not through a relative the pre-pass reads the word as — and `weak` is true
when nothing was delivered or `absent_terms` is not empty. That is not the
verdict falsified above: it asks whether a word exists in the bundle at all,
which does not move with question style or corpus size the way the two
shares did. A reader seeing `weak` rephrases in the bundle's own words, and
if it stays weak, says the bundle does not cover the question.
The checker does not read this member, for the same reason: it holds a
payload's FORM, and these lists carry no claim a form can be held to.
8. A pre-pass MAY deliver an excerpt of a large concept as the PASSAGE that
answers the question rather than the whole body. It then MUST say so, as
`passage: {start, end, of}` — whole numbers, `0 <= start < end <= of`,
character offsets of the passage in the concept's body and that body's
length — and `text_sha256` digests the delivered `text` while `sha256` stays
the concept file's, so the whole remains one fetch away by `concept_id`. The
delivered `text` MAY carry the nearest heading above the passage and markers
where text was left out, so its length is not `end - start`. The checker
refuses a `passage` that is not such a place (`passage_malformed`): a place
that is not a place sends a reader who fetches the concept to the wrong
characters of it.
9. A pre-pass MAY take several sub-questions in one run. Its payload then
carries `questions` — the list, in the order asked — in place of
`question`; every excerpt carries `subquestions`, the indices into
`questions` of the sub-questions it answered, the one whose text it carries
first; and `coverage` carries one block per sub-question under
`subquestions`, plus `weak_subquestions` and a `weak` that is true only when
every sub-question is weak. The cut is ONE: the same budget and the same `k`
one question gets, so asking several times in one run does not buy a larger
payload, and point 1's identities hold over the whole. The checker refuses
an excerpt whose `subquestions` are not distinct indices into `questions`,
or that carries them in a payload listing no `questions`
(`subquestions_unindexed`). A run of one question is the single form.
10. An excerpt whose concept's own title is a position rather than a name — a
table block a producer could only name by the line it starts on — MAY carry
as `title` the title of the concept it stands under in the same document,
and then MUST carry the file's own title as `own_title`, so the name shown
is never mistaken for the one in the file.
11. A pre-pass MAY take a FOLDER of bundles and ask every bundle under it in
one run. Its reply is then not a payload but a list of them: `asked` (the
bundle ids, in order), `budget_per_bundle`, and `answers`, one
`{bundle_id, payload}` per bundle, each payload conformant on its own and
cut to its share of the budget; `question` or `questions` as point 9. The
reply carries no `bundle` of its own, which is how a reader tells the two
apart. The checker holds every payload to every rule, names a finding with
the bundle whose payload carries it, reports once a finding every payload
carries alike, and refuses an answer labelled with a bundle its payload
does not describe (`answer_misattributed`) — a claim is attributed to the
label — and a reply with no answer at all (`payload_invalid`).

# Frozen question sets for the search gate
`tools/okf_soek_gate.py` measures what a reader actually RECEIVES from a
collection at the shipped defaults. It reads its question sets from this
directory and the collection from `--bundle`; **neither is committed here.**
**The sets are `.gitignore`d and are placed here by hand, by whoever runs the
gate.** They are INPUTS, never constants: that is the rule
`tools/okf_retrieval_gate.py` already states for a gold set, and this
directory inherits it. A set that is absent is reported
`IKKE KJOERT -- fixture mangler` and counted RED — never as 0 hits, and never
as a quiet pass. So a machine without the sets cannot mistake silence for a
green row, and nothing about anyone's corpus reaches a public mirror.
A set is **FROZEN**: it is copied verbatim from wherever it was written,
nothing here is edited to make a row go green, and a set whose bytes move is a
new set with a new name.
## The four files and the shape each must have
| File | Shape | Units |
|---|---|---|
| `fase-sporsmaal.json` | `{"questions": [{id, question, fasit: [{doc, quote}], release_only}]}` | the phase set, with a `release_only` class |
| `holdout-sporsmaal.json` | the same shape | a blind hold-out |
| `norske-sporsmaal.json` | `{"sporsmaal": {id: text}}` — the same ids, asked in plain Norwegian; the fasit is read from the phase set by id | the phase set's ids |
| `delsporsmaal.json` | `{"delsporsmaal": {id: [...]}, "operator": {question, hit_rule, gold: [{doc, section}]}, "negative": {pass_rule, questions: [{id, question}]}}` | one list per id, the operator's question by two routes, known negatives |
Each set carries its own `hit_rule`, and the gate implements it verbatim
rather than restating it: an excerpt whose `source_file` matches a fasit
entry's document **and** whose text contains that entry's quote (case folded,
whitespace collapsed). Any one fasit entry suffices. The negative set carries
a `pass_rule` instead, because a question the collection does not cover is
passed by SAYING so, not by returning nothing.
## The collection
The collection is not a fixture here either — it is far too large to commit.
Build one with today's code and point the gate at it. It is built with
`--gate none` and otherwise at the shipped defaults: the sources are the
vendor's own public documentation, and the screen is for material of unknown
origin — at the default tier it refuses some of these pages outright, and every
refused page would read here as a build failure the search never had a chance
at:
```sh
okf project <sources> --out <scratch> --gate none
python3 tools/okf_soek_gate.py --bundle <scratch>/.okf/<id>
```
`okf build <sources> --bundle <dir> --bundle-id <id> --okf-version 0.2
--gate none` writes the same concept bytes.
A gate measuring a collection nobody builds measures nothing. If the
collection is missing the gate exits **2** with its reason rather than
reporting 0 hits against nothing.

and the cut; it decides nothing about the question.
- Do not re-derive what the payload handed you.
- **The cut is one run's answer, not the bundle's.** `withheld` states the
total, the count per rule, and the best-ranked drops BY NAME with their
title and document. A near miss that looks like what you needed is a
reachable concept: run the pre-pass again with its words, or fetch it by
name. What you may not do is the two things § 9 forbids — enumerate the
directory, or reach the verdict layer.
- Know which you did. A claim resting on a concept a first run withheld is
still sourced; a claim resting on a concept you never delivered is not.
- Declare the cut in your output when the questioner asked for it. Reporting
as though you had read the whole bundle, when you were handed a bounded
window, is the denominator failure below with extra steps.
## Working method
Five steps, in this order. The pre-pass is step three, not step one: a question
asked in the wrong words reaches the wrong concepts however good the ranking is.
**1. Understand the question first.** Read the bundle's `map` before you search
it — `okf card <BUNDLE_ROOT>` prints it: one line per document with its section
titles, a series of like-named documents as one line. Pointed at a FOLDER of
bundles, the same command lists every bundle under it, each with its map, so
you see what each one covers before you choose. Then put the question
into the bundle's own words: a bundle written in one language and a question
asked in another share few tokens, and the pre-pass matches tokens. Take the
terms from the map's titles, not from your vocabulary.
**2. Split a broad question into 2–4 sub-questions.** One search for a question
with four parts returns the best eight concepts for the average of the four,
which is often the best eight for none of them. Write the sub-questions down;
they are also the shape of the answer.
**3. Search all sub-questions in ONE run. Several searches are normal, and
searching again is allowed and expected.** Give the pre-pass every sub-question
at once:
```sh
okf consume <BUNDLE_ROOT> --question "first sub-question" --question "second sub-question" --out /tmp/p1.json
```
Each sub-question is ranked alone and the answers are interleaved; every
excerpt names the `subquestions` it answered. After each run, read two things:
what came back, and what lay just outside the cut. `withheld.nearest` names
the best-ranked concepts that missed, with their titles — if one of them is
what you were after, that is a signal about the WORDS, not a closed door. Search again with the words that concept uses, or
ask for it by name. There is no limit on runs and no penalty for a run that
found nothing; a run that found nothing is a measurement, and its denominator
is worth carrying. When `coverage.weak` is true — a word of yours the bundle
holds in no form (`coverage.absent_terms`), or nothing came back — rephrase in
the bundle's own words, and if it stays weak, say the bundle does not cover it.
**4. Several bundles, one run.** When more than one bundle could answer, give
the pre-pass the FOLDER that holds them instead of one bundle: it asks every
bundle under the folder with the same sub-questions in ONE run, splits the
budget between them, and names the bundle on every answer and every excerpt.
`--bundle-id` narrows it to one of them.
```sh
okf consume <FOLDER> --question "first sub-question" --question "second sub-question" --out /tmp/p1.json
```
Keep track of which bundle each piece of material came from. A claim is
attributed to its bundle as well as its concept — two bundles can hold the same
sentence with different authority.
**5. Put it together.** Order the material by sub-question, not by rank. Where
sources disagree, decide what holds NOW: the newest documentation or the
highest version wins, and say which version you read. Say plainly what the
bundle or bundles do not cover. Then write ONE coherent answer — not a list of
excerpts with the assembly left to the reader.
## Answer form
Write for the person who asked: in the questioner's language, whatever
language the bundle is in, and in ordinary prose.
- **Plain words.** The instrument's vocabulary stays out of the answer:
not `below_k`, not `withheld`, not a `sha256`, not a budget line, not the
word denominator. Those are how the answer was produced, not what it says.
- **Short source references, as a textbook gives them**: the document and the
section, and the bundle too when more than one was read — "Brukerhåndbok § 4.2" and
not a 64-character digest. A reader who wants the file can be told where it
is; a reader who wants the answer should not have to step over the plumbing
to reach it.
- **Say what is not covered** in one sentence, in the same prose. A gap stated
plainly is worth more than a table of rules nobody reads.
- **The audit trail is a choice.** The markings, the three counts, the ref and
the rules a concept was dropped under go to a file, or to the end of the
answer, only when the questioner asks for them — or when you are producing a
document that will travel without you. Otherwise the answer is the
deliverable.
The markings below are the discipline BEHIND the prose. Every claim still has
exactly one of them and a source you could produce on request; what changed is
that the reader is not made to read the bookkeeping in order to get the answer.
- Do not go looking for context the pre-pass deliberately withheld. The
`withheld` list names each dropped concept and the rule that dropped it; if a
finding appears to need one, record it as a coverage limitation naming the
concept and the rule. A visible drop is worth more than a silent override.
- Declare the cut in your output. Reporting as though you had read the bundle,
when you were handed a bounded window, is the denominator failure below with
extra steps.

@ -51,113 +51,22 @@ You do the **judgement**. The pre-pass has already done the reading, the ranking
and the cut; it decides nothing about the question.
- Do not re-derive what the payload handed you.
- **The cut is one run's answer, not the bundle's.** `withheld` states the
total, the count per rule, and the best-ranked drops BY NAME with their
title and document. A near miss that looks like what you needed is a
reachable concept: run the pre-pass again with its words, or fetch it by
name. What you may not do is the two things § 9 forbids — enumerate the
directory, or reach the verdict layer.
- Know which you did. A claim resting on a concept a first run withheld is
still sourced; a claim resting on a concept you never delivered is not.
- Declare the cut in your output when the questioner asked for it. Reporting
as though you had read the whole bundle, when you were handed a bounded
window, is the denominator failure below with extra steps.
## Working method
Five steps, in this order. The pre-pass is step three, not step one: a question
asked in the wrong words reaches the wrong concepts however good the ranking is.
**1. Understand the question first.** Read the bundle's `map` before you search
it — `okf card examples/ingest-golden-segmented-okf-v0-2/expected-bundle` prints it: one line per document with its section
titles, a series of like-named documents as one line. Pointed at a FOLDER of
bundles, the same command lists every bundle under it, each with its map, so
you see what each one covers before you choose. Then put the question
into the bundle's own words: a bundle written in one language and a question
asked in another share few tokens, and the pre-pass matches tokens. Take the
terms from the map's titles, not from your vocabulary.
**2. Split a broad question into 2–4 sub-questions.** One search for a question
with four parts returns the best eight concepts for the average of the four,
which is often the best eight for none of them. Write the sub-questions down;
they are also the shape of the answer.
**3. Search all sub-questions in ONE run. Several searches are normal, and
searching again is allowed and expected.** Give the pre-pass every sub-question
at once:
```sh
okf consume examples/ingest-golden-segmented-okf-v0-2/expected-bundle --question "first sub-question" --question "second sub-question" --out /tmp/p1.json
```
Each sub-question is ranked alone and the answers are interleaved; every
excerpt names the `subquestions` it answered. After each run, read two things:
what came back, and what lay just outside the cut. `withheld.nearest` names
the best-ranked concepts that missed, with their titles — if one of them is
what you were after, that is a signal about the WORDS, not a closed door. Search again with the words that concept uses, or
ask for it by name. There is no limit on runs and no penalty for a run that
found nothing; a run that found nothing is a measurement, and its denominator
is worth carrying. When `coverage.weak` is true — a word of yours the bundle
holds in no form (`coverage.absent_terms`), or nothing came back — rephrase in
the bundle's own words, and if it stays weak, say the bundle does not cover it.
**4. Several bundles, one run.** When more than one bundle could answer, give
the pre-pass the FOLDER that holds them instead of one bundle: it asks every
bundle under the folder with the same sub-questions in ONE run, splits the
budget between them, and names the bundle on every answer and every excerpt.
`--bundle-id` narrows it to one of them.
```sh
okf consume <the folder that holds the bundles> --question "first sub-question" --question "second sub-question" --out /tmp/p1.json
```
Keep track of which bundle each piece of material came from. A claim is
attributed to its bundle as well as its concept — two bundles can hold the same
sentence with different authority.
**5. Put it together.** Order the material by sub-question, not by rank. Where
sources disagree, decide what holds NOW: the newest documentation or the
highest version wins, and say which version you read. Say plainly what the
bundle or bundles do not cover. Then write ONE coherent answer — not a list of

Five opcodes, and a decoder implementing only the first is wrong on real
files: an encoded run, an absolute run (whose byte count is padded to an
even length), a delta that SKIPS pixels, end-of-line and end-of-bitmap.
Skipped pixels keep index 0, which is what the format says and what an
independent decoder produces.
THE COST IS THE FRAME, NOT THE STREAM. The rows are allocated once from the
declared size -- already bounded by `check_size` before this is called --
and each run is written as one CLIPPED slice. Painting pixel by pixel would
leave the memory bounded and the CPU unbounded: a megabyte of `FF` runs is
a hundred million paint steps against a frame of 32 pixels.
A STREAM THAT NEVER SAYS IT IS FINISHED IS REFUSED, and that is the
difference between a skipped pixel and a missing one. Running out of bytes
leaves the rest of the frame at index 0 -- indistinguishable, in the
output, from a delta that skipped it, which is why every decoder agrees on
the wrong picture: measured 2026-09-19 on a real 352x548 R761 asset, a
stream cut to 90 % was carried with 13 923 pixels wrong, to 50 % with
95 890, to 10 % with 166 525, with no code and no row. So the loop may end
HERE and nowhere else, and `_bmp_flat_rows` refuses the same shape with the
same code.
The terminator is checked rather than `biSizeImage`, which is a claim by
the same untrusted header. Read off the corpus: over the 25 RLE8 BMPs
the frozen R761 delivery ships (24 distinct; the bundle carries 19 of
them, the rest being an unpointed duplicate and four no concept names),
25 of 25 end at an explicit
end-of-bitmap, on 25 of 25 it is the stream's LAST two bytes, and on 25 of
25 `biSizeImage` equals the available bytes -- so requiring it costs
nothing measured here, and a whole stream that omits it is refused
alongside a cut one because from the reader's side they are the same bytes.
AND THE TERMINATOR ALONE IS NOT A COVERAGE PROOF, because a stream may say
it is finished anywhere: measured 2026-09-19, one whose FIRST two bytes are
the end-of-bitmap escape was carried with every pixel of the frame never
decoded. So the cursor must also stand at or past the end of the last row.
THE LINE IS THE CURSOR AND NOT THE PIXELS, and that is a format argument
rather than a corpus one -- the corpus cannot choose between the two, since
25 of 25 of those files paint every pixel, 25 of 25 reach the end of the
frame and 0 of 25 use a delta. A pixel-coverage count would refuse both
constructions the format defines.
BUT A CURSOR THAT MOVED IS NOT A SKIP THAT WAS STATED, and the round that
wrote the cursor rule claimed more than it had measured: it said a delta
escape and an end-of-line escape both leave pixels every decoder agrees
on. Only the delta does. A delta states a DISTANCE, so an independent
decoder passes over exactly the same pixels; an end-of-line states "the
rest of THIS row", so an end-of-line at column 0 closes nothing and claims
a row the stream never wrote. Measured 2026-09-19: four end-of-line
escapes and an end-of-bitmap carried an 8x4 frame with 32 of 32 pixels
never decoded, and Pillow refuses those same bytes. So an end-of-line at
column 0 is REFUSED, and so is a delta whose horizontal offset would leave
the row -- the format puts that offset inside the line, and a reader that
keeps the cursor past the row end and a reader that rolls it into the next
row draw two different pictures from one stream.
THE DIRECTION THAT IS CLOSED, AND THE ONE THAT IS NOT. Over every opcode
sequence of length 1 to 4 on a 4x3 frame -- 22 620 streams, swept in
`tests/test_asset_viewable.py` rather than curated -- this reader carried
703 streams the independent decoder refuses and drew 1 492 more
differently. With these two clauses: 0 and 32. All 32 remaining are a run
or absolute block that OVERRUNS its row, which this reader clips at the
row end and Pillow spills into the next one. That last class is STATED
rather than closed, because closing it costs pictures: 15 of the 25 real
files overrun a row, and refusing them would drop 15 real figures and move
a pinned bundle's bytes. The two clauses that shipped cost nothing
measured -- over 11 441 files scanned across four raw standard deliveries
and the K2 reference corpus, the only 25 BMPs on this machine use an
end-of-line at column 0 in 0 of 25 and a delta in 0 of 25, and 25 of 25
still decode to Pillow's pixels exactly (3 117 220 compared).

stdlib file types that carry images with no `[extract]` extra installed, so
a Pillow-based converter would either make a core path depend on an
optional binary wheel or buy this package its second runtime dependency.
Second, and decisive: an asset's name is its content digest, so the bytes

installed library would make that identity move with the library's version
-- the exact property 0.10.0 felled page rasterisation over. `encode_png`

"""BM25 over a bundle's concepts: the default ranking of `okf consume` (v1.1 C1).
WHY IT REPLACED THE FUSION. The earlier ranking fused three signals -- token
overlap with the title, token overlap with the body, and a document prior --
and two of them rewarded the wrong thing on a large collection: the document
prior favoured big documents full of common words, and the rarity weight gave
its MAXIMUM weight to a word that occurs nowhere in the collection. BM25 has
neither property, needs no new dependency, and ranks in milliseconds. The
measurement that chose it lives with the measurement; this module states the
mechanism.
TWO SIGNALS, FUSED BY RANK.
- **Passage** -- every body is cut into windows of `WINDOW_CHARS` characters
every `WINDOW_STEP`, each window is a BM25 document, and a concept scores its
BEST window (pure max). A narrow factual question is answered by one place
in a concept, and a sum over windows -- even a damped one -- rewards a long
concept for mentioning a word often.
- **Field** -- one BM25 document per concept: its title three times, its
directory path and source file name twice, then its body. A broad question
is answered by what a section is CALLED, and a passage never sees the title.
Fused by reciprocal rank (`RRF_K`, the constant the old fusion used). A signal
that scored a concept zero contributes nothing to it, and concepts that tie
within a signal share the group's first rank -- so neither a word the
collection lacks nor alphabetical order can lift a concept.
**A word the collection does not hold weighs exactly zero** (`idf` of a term
with `df == 0`), which is the property the old rarity weight had backwards.
Deterministic: every sort breaks ties by `concept_id`, and no float leaves this
module except as an ordering key.

"""The map of a bundle: its documents and their titles, in its own words (v1.1 C5).
WHY IT EXISTS. The ranking matches words, and a question put in words the
collection does not use finds little however good the ranking is -- a question
asked in one language of a collection written in another most of all. The
reader closes that gap by rewriting the question into two to four
sub-questions in the collection's OWN words, and the one place those words
are listed is the collection itself. This module lists them, compactly enough
to be read before the first question: one line per source document, its name
and then the titles of its concepts in document order.
A SERIES IS ONE LINE. Documents whose names differ only in their numbers -- a
changelog per release, a note per week -- are one kind of document, and four
hundred lines saying so crowd out everything else a reader needs. They are
written as one line: the name with every number as `#`, how many documents,
the first and the last by natural order, and the titles across the series that
are words (a title that is only a version number names nothing).
DERIVED, NEVER STORED, like the card that carries it: the map is recomputed
from the bundle on every call, so it cannot disagree with the bytes beside it.
Deterministic: every order is by name, by position or by a count with the
name breaking ties.

- `asset_samples_invalid` — the sample buffer does not fit the dimensions
the image dictionary declares. Refused rather than padded: a short buffer
means the dictionary was read wrong
- `asset_too_large` — the picture is over this package's bound: because it
DECLARES a size beyond `MAX_IMAGE_PIXELS`, because the file itself is
that large, because the stream behind it DECOMPRESSES to more than
`MAX_IMAGE_BYTES`, or because one link of its filter chain would COST
more than `MAX_FILTER_DECODE_BYTES` to decode. The four are one code
because they are one decision — this run will not hold that picture —
and because a consumer counting refusals wants the picture, not the
mechanism. Each bound is read off the corpora and sits an order of
magnitude above anything measured
- `asset_size_invalid` — the container declares a size that is not a size:
a zero or negative `/Width` or `/Height`. DISTINCT from
`asset_too_large`, because the two say different things about the
document — one is a legitimate publisher shipping a picture bigger than
this package carries, the other is a dictionary written wrong or written
to be read wrong — and counting them together would make a corpus
statistic about the first untrue. Refused before the stream is read: a
negative dimension multiplies to a negative pixel count, under which
every bound reads as satisfied
- `asset_not_viewable` — the bytes are a real image in a format no model
can be SHOWN (TIFF, JPEG 2000), and this package has no lossless
conversion for it. DISTINCT from `asset_type_unknown`, which says the
bytes are not an image at all: this one says they are, and carrying them
would put a file in the bundle that the `images: N` count reports as
arrived and nothing downstream can read. Measured 2026-09-19 on the
frozen R761 delivery: 19 of its 50 assets were carried in exactly that
condition, as RLE8 BMP
- `asset_bmp_unsupported` — a BMP variant this reader does not express
(RLE4, BITFIELDS, 16- or 32-bit samples, a 12-byte BITMAPCOREHEADER, a
palette over 256 entries). DISTINCT from `asset_not_viewable`, which
says there is no conversion route for the format at all: this one says
there is one and this file is outside it, which is a different fact
about the document and a different thing to go and fix
- `asset_pdf_unbounded` — the image is reached through a PDF stream filter
this package has no measured cost ratio for (`LZWDecode`,
`RunLengthDecode`, `CCITTFaxDecode`, `/Crypt`, anything unknown), or
through an encrypted stream it cannot decipher. DISTINCT from
`asset_too_large`, which says a measurement was taken or predicted and
came out over the bound: this one says neither was possible, so the
picture is refused UNREAD rather than decoded to find out what it costs.
Measured 2026-09-18: bounding only the first link of a filter chain let
1 636 bytes of PDF cost 886 554 624 bytes of peak RSS, and bounding
every link's OUTPUT still let 33 475 bytes cost 3 261 599 744 through a

"""The PDF stream filters an image may be reached through, by NAME.
TWO CLASSES, and what separates them is HOW the cost of a link is bounded,
never whether the link is safe. Every one of them is bounded.
* `FlateDecode` is MEASURED as it is paid: inflated a chunk at a time,
refused the moment the running total crosses the bound, with the output
discarded unless a link behind it has to be measured from those bytes.
* `ASCII85Decode`, `ASCIIHexDecode`, `DCTDecode`, `JPXDecode` and
`JBIG2Decode` are PREDICTED before they are paid: each carries a measured
worst-case cost per byte of input (`assets.PDF_FILTER_COST_RATIO`), and a
link whose input times that ratio is over the budget is refused before
its decoder is called. Their decoders take a whole string and return a
whole string, so there is no moment between the two at which a cost could
be observed.
0.10.1 had a third class, and it was WRONG. `ASCII85Decode` and
`ASCIIHexDecode` were called bounded "by their own input because they
shrink". `z` is ASCII85's shorthand for four zero bytes, so that filter
QUADRUPLES its input, and `base64.a85decode` appends one 4-byte object per
group to a list, so it costs about a hundred bytes of memory per byte of
input. Measured on the pinned tree, its own interpreter, idle machine: a
33 475-byte PDF decoding through `[/FlateDecode /ASCII85Decode]` cost
3 261 599 744 bytes of peak RSS and the picture was CARRIED. Under the
ratios it is 42 070 016 bytes and `asset_too_large`, and at twice the run
of `z` -- which trebled the old cost to 6 461 558 784 -- it is 40 280 064:
the cost no longer follows the bomb.
EVERYTHING ELSE IS REFUSED with `asset_pdf_unbounded` before any of the
stream is decoded -- `LZWDecode`, `RunLengthDecode`, `CCITTFaxDecode`,
`/Crypt`, and any filter written after this one. A filter with no measured
ratio has no budget to be checked against, and decoding one to find out
what it costs IS the failure this bound exists to stop. Refusing an unknown
name rather than passing it through is the same decision
`corpus.resolve_gate` takes for an unknown gate name: a fallback reproduces
the defect with an extra step.
The reach is measured rather than assumed. Over the 9 668 image objects of
the 77 PDFs on this machine (2026-09-18, enumerated through pdfminer's own
page walk), the filter chains are 6 235 `[/FlateDecode]`, 2 459
`[/DCTDecode]`, 596 `[/FlateDecode /DCTDecode]`, 296 `[/Fl]`, 42
unfiltered, 16 `[/ASCII85Decode /FlateDecode]`, 16 `[/JPXDecode]` and 8
`[/CCITTFaxDecode]`. The refused class is those 8 objects, 1-bit stencil
masks (`/ImageMask true`, `/BitsPerComponent 1`) already refused one step
later by the encoder. The largest input any `ASCII85Decode` link is handed
is 450 739 bytes, more than ten times under the budget's cap, which is why
the cap costs no picture the corpora hold.

`check_size` reads `/Width` and `/Height`, which an untrusted document
writes and which say nothing about what `get_data()` will return: `/Length`
is the COMPRESSED length, and a dictionary declaring 1x1 may hang 400 MB of
deflated zeros off it. Measured by an independent review of 0.10.1 on
`230d1cb`: that document is 408 516 bytes, was carried without a rejection,
and cost 892 MB of peak RSS -- the same failure mode the 0.10.0 review
named, reached through the other number.
THE CHAIN, NOT ITS FIRST LINK. 0.10.1 measured `filters[0]` and returned,
which is not a bound: a PDF decodes a stream through a LIST of filters, and
`/Filter [/FlateDecode /FlateDecode]` puts the whole expansion in the
second one. Measured 2026-09-18 on `0f308c1`: 1 636 bytes of file became
886 554 624 bytes of peak RSS, and three links did the same from 1 070
bytes -- about 542 000x the file, and the picture WAS refused at the end,
by `check_payload`, after the memory had been spent. It also left the 16
corpus objects behind an `[/ASCII85Decode /FlateDecode]` chain unmeasured,
because `filters[0]` is not `FlateDecode` there.
AND THE COST OF A LINK, NOT THE SIZE OF ITS OUTPUT. Bounding every
`FlateDecode` was still not a bound, because the bomb moved into a link
0.10.1 had documented as safe: `ASCII85Decode`'s `z` is the shorthand for
four zero bytes, and its decoder holds about a hundred bytes per byte of
input. Measured on the pinned tree: 33 475 bytes of file cost
3 261 599 744 bytes of peak RSS and the picture was CARRIED. Three rounds
of this review each bound an OUTPUT and the bomb stepped one link along;
what they had in common is that a decoder's working set is not its output.
So every link is walked, in order, and each is given a BUDGET
(`assets.MAX_FILTER_DECODE_BYTES`) rather than a class:
* a filter with no measured cost ratio is refused BEFORE anything is
decoded (`bounded_pdf_filters` says which, and why);
* a `FlateDecode` is measured as it is paid, under a limit that is the
smaller of the picture's own bound and what the NEXT link's decoder may
be handed -- which is how the budget travels down the chain instead of
being applied to each link in isolation;
* the last `FlateDecode` in the chain has its output counted and thrown
away, which is the common case and costs exactly what 0.10.1 cost; an
earlier one is inflated under the same limit and handed on, so the link
behind it can be measured from real bytes;
* every other filter has its cost PREDICTED from its input size and its
measured ratio, and is refused before its decoder is called.
WHAT THIS STILL DOES NOT BOUND, stated rather than implied: a stream
something else has already decoded (`_pdf_stream_bytes` returns `None`),
where the memory is spent before this package is asked. That one is caught
by `check_payload` AFTER `get_data()`, which makes it a counted refusal

"""Expose OKF bundles over the Model Context Protocol, in two shapes.
Beside `skill.py` because it belongs to the same class: a way to put a bundle
in front of an agent. The skill hands a consumer a document telling it which
command to run; this hands it a set of tools a client calls. Neither ranks
anything of its own -- both reach `consume.build_payload`, which stays the one
reading direction this library has.
TWO SHAPES, ONE IMPLEMENTATION.
* `--bundle PATH` serves exactly ONE bundle, fixed at startup. The bundle
tools take no bundle argument, because there is nothing to choose.
* `--root PATH` (repeatable) serves every bundle found under the roots, and
knows NONE of them by name. Discovery happens per call, so a bundle added,
removed or rebuilt while the process runs is seen by the next call without a
restart, a configuration edit or a code change.
NOTHING IS CACHED ACROSS CALLS, AND THAT IS THE DESIGN RATHER THAN AN
OVERSIGHT. A server that read the bundle list once at startup would keep
answering after the bundle was rebuilt, with an identity that no longer
describes the bytes -- and an answer from yesterday's bundle is the one
failure a consumer cannot see from the outside. Every call re-walks the roots
and recomputes `bundle_ref`, so the identity in an answer is always a fact
about the bytes on disk at the moment of the call. The cost is real: the
identity is a sha256 over the whole concept tree, and it is paid per call.
WHY THE PROTOCOL IS WRITTEN HERE AND NOT TAKEN FROM AN SDK. This package
declares exactly one runtime dependency, the security guard, and
`tests/test_packaging.py::test_the_only_runtime_dependency_is_the_security_boundary`
pins that list literally. An MCP SDK would be the second, on the DEFAULT
install path, for four JSON-RPC methods and a newline framing -- so the
protocol is written narrowly, with stdlib only, and the packaging invariant
stays a fact rather than an intention. Chosen over the SDK because the surface
needed is `initialize`, `notifications/initialized`, `tools/list` and
`tools/call`, and nothing here needs resources, prompts, sampling or progress.
CONTAINMENT IS TWO INDEPENDENT CHECKS, NEVER ONE. A concept is reachable only
if the bundle's own index names it (`consume.enumerate_concepts`, which
refuses a target climbing above the root) AND its resolved path is inside the
bundle (`connectors.safe_resolve`, on canonical paths). Either alone would be
defensible; the pair is what makes a defect in one of them survivable.
AND IT IS EVERY READ PATH, not the one tool that happened to have it. Until
`consume.resolve_in_bundle` existed, the second check was made by `okf_fetch`
alone: `okf_ask` and `okf_describe` joined the index's own name onto the root
and opened whatever was there, so a link out of the bundle was read and
delivered. The index rule is a STRING rule -- it cannot see a symlink -- which
is exactly why one of the two checks is not enough.

rule about how a document is cut but a screen about whether a document may be

default while saying nothing about it. The default is `okf build`'s default,

with 0 findings.
**The argument for a generator never rested on conformance, and still does
not.** It was made on what the skill has to state: SS 5's denominators, the
payload-cost section and SS 6.4's conditional-field list are all per-bundle
numbers, and a generic skill can either leave them as holes -- the template's
own definition of unfinished -- or carry another corpus's numbers, which is
worse.
**AND IT LOST 2026-09-20, TO A THIRD OPTION AND AN OPERATOR'S MEASUREMENT.**
The third option is `okf card`: the per-bundle numbers are DERIVED from the
bundle in under a second, so the generic skill neither invents them nor states
another bundle's -- it names the command that produces them. The measurement
is that the per-bundle form's cost is not hypothetical: it goes stale the
moment its bundle is rebuilt, one copy per consuming project, and a project
holding two bundles installs two near-identical skills (measured: identical on
281 of 313 and 311 lines). So `okf skill --out <dir>` writes the GENERIC form,
`okf project` installs it under one name that carries no bundle id, and
`--for-bundle` is the opt-in for the instantiated copy. That copy still
refuses out loud (`bundle_mismatch`) rather than answering from stale numbers,
which is what makes it safe to keep and not enough to keep it default.
not.** It was made on what the skill has to state:
§ 5's denominators, § 7.6's breaking point and § 6.4's conditional-field list
are all per-bundle numbers. A generic skill can either leave them as holes -- the
template's own definition of unfinished -- or carry another corpus's numbers,
which is worse, because a stated cost that is false for this bundle is a
measurement failure and not merely a gap. Instantiating is what makes them true.
And with several bundles connected at once, a generic skill has nothing to
select on: each generated skill carries the bundle's id in its own name.
**Zero model calls, zero network, no clock.** The same bundle bytes produce the
same skill bytes.

@ -175,67 +175,6 @@ The version range that carries this lives in `pyproject.toml`'s
`[project.optional-dependencies] extract`, with the same reasoning at the
declaration site.
## The content-accounting fixtures (`accounting/`)
The fasit side of `tools/okf_accounting_gate.py`. `accounting/corpus/` holds
one document per row of README's file-type table (13 of 13) plus a `graphics/`
directory next to them that the HTML, STS and markdown documents point at --
the layout under which a picture is carried through a document AND booked as a
rejected file. `accounting/rejected/` holds one HTML document with a
zero-width space in its prose, which the guard refuses at every tier, and the
image it points at.
`inventory.json` and `rejected-inventory.json` are what `tools/okf_witness.py`
counts in those two directories, committed as data and regenerated only with
that tool:
```
python3 tools/okf_witness.py tests/fixtures/accounting/corpus > tests/fixtures/accounting/inventory.json
python3 tools/okf_witness.py tests/fixtures/accounting/rejected > tests/fixtures/accounting/rejected-inventory.json
```
Seven more documents were added 2026-09-18, one per format that had element
types it could never exercise. An independent review measured **20 of 63
element types with a count of ZERO in their only fixture**, which is why six of
seven witness mutants survived the suite: a witness cannot be caught being
wrong about something it never sees. They are written part by part by
`make_accounting_fixtures.py` in this directory, for the same reason the XML
fixtures are hand-written:
```
python3 tests/fixtures/accounting/make_accounting_fixtures.py
```
| Fixture | What it carries that nothing else did |
|---|---|
| `topptekst-og-kommentar.docx` | A header, a footer, a comment, an endnote and a **text box** -- and a footnote, a table and a heading, three types the only other docx has at 0. The header says "Utkast - gjelder ikke etter 2026-01-01" and the comment says the requirement does NOT apply in tunnels: two statements that reverse the document's meaning and that the build carries none of. |
| `notater-og-skjult.pptx` | A **speaker note** and a **hidden slide** (`show="0"`), plus a table and paragraphs. A hidden slide counted as an ordinary one is indistinguishable from one that is shown. |
| `skjult-ark-og-formel.xlsx` | A **hidden sheet**, a **formula** (`<f>B2*2</f>`) and a **picture**. The picture is what makes the operator's `.xlsx image` exception exercisable at all: the old fixture had none. |
| `liste-og-bilde.odt` | A **header and footer** (they live in `styles.xml`, so a reader of `content.xml` cannot see them), an **annotation**, a list and a picture. |
| `bilde.rtf` | A `\pict` picture: the rtf witness's image count was 0 in its only fixture. |
| `figur.html` | A picture and a table under `.html`; `side.htm` gained one too, so `.htm` and `.html` each exercise `image`. |
| `sts-rikt.xml` | A **`mixed-citation`**, an **`mml:math`**, a **`fig` with a caption**, a table with a label, cells, a list item and a footnote -- six STS roles the R761 delivery does not contain at all, which is why the gate's only real corpus could not see the hole in the role map. |
### The hand counts
Row 1's fasit is the witness's own output, so a hand count is the only number
in this loop the witness did not produce. Four of thirteen documents had one;
**all twenty have one now**, in `HAND_COUNTS` in
`tests/test_accounting_gate.py`, and `test_the_hand_counts_cover_every_document_of_the_corpus`
fails if a document is added without one. Each was counted by reading the
fixture's own bytes -- the XML parts of a zip, the control words of the rtf,
the objects of the PDF -- never by running the witness and writing down what
it said.
`witness/prosess-84-sts.twin.json` is the STS document written by hand in the
publisher's JSON node form (`standardContent`, nodes with `e`/`t`/`x`), so the
two STS witnesses can be compared on a fixture as well as on R761. Eight of
the thirteen documents are byte copies of fixtures documented above
(`image-inbox/`, `k2-office/`, `prisark.xlsx`); the other five
(`notat.md`, `logg.txt`, `mengder.csv`, `parametre.json`, `side.htm`) are
written here, and `notat.md` carries a fenced `# ...` line that is not a
heading.
## What these fixtures do not cover
Structured table recovery. Measured on real Vegnormalene, only 45 of 196

"""The accounting corpus's SECOND document per format: the elements the
witness could not see until 2026-09-18.
An independent review of the gate found that the witness -- and therefore the
whole accounting, because rows 2 and 3 require the build's inventory to EQUAL
it -- counted no header, no comment, no speaker note, no hidden sheet, no
formula, no citation and no figure caption. What nothing counts, nothing can
lose visibly. It also found that 20 of 63 element types had a count of ZERO in
their only fixture, so six of seven witness mutants survived.
These documents are written BY HAND, part by part, for the reason the XML
fixtures state: a library that writes and then reads its own format proves
only that it agrees with itself. Every count they carry is written down in
`tests/fixtures/README.md` by a person reading these strings, not by running
the witness over them.

"""The adjudication command: it records a judgement, and never invents one.
A proposal a human has not looked at must never be replayable as an
adjudication, because replay is exactly what the run path does with a plan --
deterministically and forever. So this command writes a SIBLING record and
leaves the proposal untouched: the two files together say who judged what,
when, and how long it took, and either can be re-read against the other.
Three properties are pinned here rather than described:
- **The model leg is OFF by default.** Pre-annotation has been measured
LOWERING a good annotator's accuracy, from 98.1 % to 95.8 %, so a leg that
cannot be switched off is a leg whose value can never be measured. With it
off, no process is spawned at all -- asserted by breaking `subprocess.run`.
- **The CLI is named, and the other one is excluded BY NAME.** The model leg
shells out to the `claude` CLI. `gemini` is not merely unmentioned; its
absence from the module is a test, because "we did not use it" and "nothing
stops us using it" look identical in a review.
- **Dwell time travels with the verdict** (PM decision B2). A ratified flag
with no per-item time is unfalsifiable, and it is the same number that makes
adjudication throughput measurable at all.
It lives outside `src/`, so it never enters a wheel and no consumer's install
surface changes because it exists.
