chore(release): prepare 1.1.0 — version sync, changelog, front-page limitations

Version 1.1.0 in pyproject, the package, uv.lock and every README install
line; the "current tag" entry moves to v1.1.0 and v1.0.0 becomes history.
The CHANGELOG states what a user notices: BM25 ranking on passages and
titles, sub-questions in one call, a map per bundle, a weak-coverage
signal, one generic skill plus the server as the standard way in over a
folder, --gate in okf project, and okf-consumption/2 as BREAKING for a
reader of withheld. Known limitations gain the vocabulary route through
the map, the retrieval gate's red rows as they stand under BM25, the
answer smoke test (no corpus content, no counts) and unmeasured speed.

eval/svar/ is ignored the way eval/soek's sets are: answers about a
consumer's corpus are inputs, never committed. No tag, no push.

+## [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.

+  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.

+- **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:
+  `docs/2026-09-19-eol-stroemmen-som-ikke-maler.md`.
+- **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.

+- **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.

+  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

+## 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.

+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

+`--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

+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.

+Eight rows, exit 0 only when every one is green, 1 otherwise, 2 for wrong

+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

+`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

+Four tools on a multi-bundle server and **three** on a single-bundle one —

+| `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 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
+> not build.** A declared size and a decompressed stream size are two
+> independent numbers: `/Length` is the COMPRESSED length, and nothing in the
+> dictionary states what `get_data()` returns. A second independent review
+> measured a 408 516-byte PDF declaring **1x1** and carrying 400 MB of
+> deflated zeros being CARRIED, with no rejection, at **892 MB of peak RSS** —
+> the same failure mode this round set out to close, reached through the other
+> number. The bound was real and it bound the wrong thing. What this round
+> DID close is the declared size and the `data:` URI; the stream itself is
+> bounded from `docs/2026-09-18-bildestien-holder-0-10-1.md`, and the
+> paragraph below about a verbatim file is corrected there too.
+
+**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.

+## 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
+> `/Filter [/FlateDecode /FlateDecode]`: 1 636 bytes of file, 889 573 376
+> bytes of peak RSS, still refused at the end by the backstop after the memory
+> was spent. The sentence below that the measurement "runs before
+> `get_data()`" is true; the sentence in the section after it, that the
+> measurement covers the case where "`FlateDecode` is the first filter", was a
+> bound on the first link and was therefore not a bound. The round that closes
+> it, with the three classes of filter and the refusal for the ones no chunked
+> measurement can reach, is
+> [`docs/2026-09-18-filterkjeden-og-backstoppen.md`](2026-09-18-filterkjeden-og-backstoppen.md).
+> That round also found the backstop this paragraph leans on had **no test at
+> 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]`, 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 |

+earlier and under a code that says why. No other rejection moves.

+
+Eight mutations, one line each, in the class the order named. The harness runs

+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.

+# 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` |

+| `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 |

+
+**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.

+                                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.

+# 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` |

+| H4 | the mutation harness is not a gate | `verdict(survived, errors)` | `6abe4b4` -> `f5b263f` |

+| — | 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

+   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.
 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.

+   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
    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

+  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

+- **Say what is not covered** in one sentence, in the same prose. A gap stated

+
+    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).

+"""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.

+
+    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.

+    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

+    second one. Measured 2026-09-18 on `0f308c1`: 1 636 bytes of file became

+
+    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

+    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

+"""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.

+is that the per-bundle form's cost is not hypothetical: it goes stale the

+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 --

+
+`inventory.json` and `rejected-inventory.json` are what `tools/okf_witness.py`

+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

+|---|---|
+| `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. |

+**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.

+"""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.

-#: Two independent builds of it differ in NOTHING (`diff -rq`), including
-#: `log.md`, which carries the corpus path and never the bundle's own.
-#:
-#: CONCEPT IDS MOVED IN THIS REBUILD, and not only because the count did.
-#: Round 9 strips pandoc's `{#sheet-N}` / `{#slide-N}` anchor where a title is
-#: formed, and a concept's filename is reduced FROM its title, so TWO ids on
-#: this bundle are renamed:
-#:   del-ii-bilag-7-prisskjema/prissammenstilling-sheet-1 -> .../prissammenstilling
-#:   del-ii-bilag-0-dokumentliste-del-ii/ark1-sheet-1     -> .../ark1
-#: The first is an id `portfolio-optimiser` has cited in writing. The rename
-#: was authorised by the operator on 2026-09-09 after the exposure was counted:
-#: 2 of 810 concepts on the previous default and 2 of 1108 on Arm B.

-#: `--close-span-gaps` each moved it by NOTHING, which is the point of both --

-#: 436 -> 453 with round 9's `--contents-name`, which does add concepts: a run

-#: names the quota as its cause by turning it off. What the gain is NOT: hit@8
-#: scores whether the gold DOCUMENT appears among the delivered excerpts, and a
