524ade78a6 chore(release): v0.4.0 
Phase 2 ships: Doors B and C, the extraction registry, the guard adapter,
and with them the first and only runtime dependency this library takes.
The minor bump is the news consumers are waiting on -- installing the
package now installs llm-ingestion-guard>=0.2,<0.3, though importing it
still does not import the guard.

Two behaviour changes carried in the same release are called out in the
changelog rather than buried: an extraction title containing `[` or `]`
now fails at manifest load (ingest-spec section 4), and the section 3
ownership scan no longer deletes files another manifest stamped into the
same bundle.

uv.lock was stale -- it predated the guard dependency and could not be
regenerated, because the guard is not on a package index. A
[tool.uv.sources] entry pins the same tag the README documents, so
`uv lock`/`uv sync` resolve. It is uv-specific dev metadata: the built
wheel still carries `Requires-Dist: llm-ingestion-guard<0.3,>=0.2`,
verified against the wheel, so the range remains the pin and the git URL
remains a channel.

Binary extraction (pdf/docx/xlsx behind [extract]) is deliberately not in
this release and is stated as outstanding in both README and changelog.

425 tests green; ruff, ruff format and mypy --strict clean.

0b77c58a1c docs(plan): correct the Phase 4 parity oracle and the catalog re-pin premise 
Both were wrong, and the convention owner corrected them: this library is not
a marketplace plugin, so there is no catalog ref to re-pin -- the integration
is a registry entry in the catalog's parity gate. And the catalog's vendored
okf-check.mjs is not byte-identical to okr's (~141 differing lines of code, an
intentional layer-1 floor), so it cannot serve as a conformance oracle. Parity
is behavioural over the spec section 3 floor in default read-mode, per file,
measured by that gate over an adversarial corpus.

241e00f27a feat(guard): wire Doors B and C to the real guard (Phase 2 step 4) 
Adds llm_ingestion_guard>=0.2,<0.3 as this library's first and only runtime
dependency, and guard_adapter.py -- the one module that imports it. The flows
themselves are unchanged: they still take an injected gate, and importing the
package still does not import the guard, so a Door A consumer is unaffected by
the dependency's state.

Door B screens the exact bytes it persists. The guard's §6 bookends
(prepare_input -> model -> screen_output) assume a model call in between; this
library makes none, and prepare_input returns prompt-shaped text (sanitized
AND spotlight-fenced with a per-call nonce) that must never reach disk. So the
adapter calls screen_output alone, on the extracted text as it stands, and
hands that same text back -- the verdict is then a statement about the bytes
actually written. This supersedes the plan's "bookends" wording, recorded
there under "Settled during implementation (step 4)".

It follows that the gate refuses rather than repairs: a file carrying an
invisible carrier is rejected, not stripped and persisted. Sanitizing first
would write a document differing invisibly from the operator's file while
source_sha256 still points at the original bytes. Operator decision; the
policy is PRESET_USER_UPLOAD, so any finding at all is held back.

Door C hands the bundle over whole to okf.import_bundle, which resolves the
cross-link graph across concepts. Per-concept reasons are derived from the
scan findings (severity:label) because stamp_concept keeps the disposition and
drops the reason strings behind it.

Assumption B1 closes as a signature smoke test over what the adapters actually
call -- screen_output and okf.import_bundle signatures, the Disposition values
both doors compare by value, the Origin/Channel vocabularies Door C validates,
the result fields read, and the upload preset's shape. prepare_input is not
pinned: drift there cannot reach this library. Behaviour is pinned against the
real scanner too, including the persist-gate proof that a fail-secure fixture
leaves the bundle byte-identical.

B2 closes with it: git+https tag install over anonymously readable HTTPS, no
credential. A direct reference is an install-time channel, not the pin -- the
range stays in pyproject, is satisfied by the tag install today, and resolves
normally once the package index exists. A packaging test enforces that the
guard remains the only runtime dependency (verified by hand-mutation).

f10fc60de2 feat(import): Door C flow against an injected import gate (Phase 2 step 5) 
Reads an external OKF bundle as {bundle-relative path -> document text},
hands it WHOLE to an injected gate over the guard's okf.import_bundle (a
bundle-level call: it resolves the cross-link graph across concepts), and
merges only concepts clearing the non-blocking floor. Same injection pattern
as Door B, so the core stays dependency-free while the CI channel for the
real guard is settled.

Two constraints shaped the design and are pinned by tests:

- A merged concept is written VERBATIM. Stamping provenance into it would
  require round-tripping its frontmatter through this library's line-oriented
  parser, which cannot represent the block lists the guard's parser accepts --
  silent data loss -- and would persist bytes the guard never screened.
- Ownership is therefore proven by content identity: identical bytes at the
  target name are a no-op re-merge (re-import of an unchanged bundle is
  idempotent), and anything else at the name is refused. Curated content and
  an updated concept are refused alike; refusing is what never destroys.

The floor is fail-closed beyond the plan's "no error" wording: an error, an
unrecognised disposition, and a concept the gate returned no verdict for are
all refusals. quarantine_review stays its own bucket, as at Door B.
origin/channel are validated against the guard's pinned vocabulary -- it
derives trust from origin by enum identity, so an unrecognised string would be
silently downgraded rather than caught.

Three primitives promoted for reuse rather than duplicated:
reduce_to_id_grammar and check_filename_length to materialize.py, and
extract.decode_text. Door C slugs the WHOLE concept path, so tables/users.md
and views/users.md stay distinct. Concept discovery folds case explicitly
rather than globbing *.md, whose case-sensitivity follows the filesystem and
would import the same bundle differently on APFS and ext4.

README's "what is gated today" section corrected: it claimed nothing is gated,
which is no longer true, but the honest statement is narrower than "the doors
are gated" -- the library cannot verify that an injected adapter is a real
guard, and a permissive stub is believed.

405 tests green; ruff, ruff format and mypy --strict clean.

d812a839be feat(inbox): Door B flow against an injected guard gate (Phase 2 step 3) 
`process_inbox(inbox_dir, bundle_dir, ingested_at, *, okf_type, gate)`:
per dropped file, bytes -> extract_text -> guard gate -> render -> collision
gate -> write -> index link. Returns an InboxResult whose four buckets
(persisted / quarantined / rejected / failed) are disjoint and complete, so a
file that vanished shows up as a missing entry rather than as nothing.

The guard is INJECTED rather than imported. The library calls no guard
function and makes no security decision: the Gate adapter returns a
GateDecision carrying the guard's own disposition value and the sanitized
text, and the flow only branches on it. That keeps the core dependency-free
while B2 (the guard's CI channel) is still open, and lets the persist and
refuse branches run deterministically against a test double.

Decisions taken with the operator this session:

- What is persisted is the gate's SANITIZED text, not the extracted text.
  Screening one string and writing another would make the verdict a statement
  about bytes nobody kept. `sanitize` is exported by the guard precisely for
  callers composing the checklist themselves, so this is sanctioned API, not
  a reimplementation. Door B has no model call, so the fenced text the
  bookends produce for a transform is never persisted.
- Quarantine is reported apart from rejection. QUARANTINE_REVIEW means "hold
  for human review" — an operator queue — where FAIL_SECURE is a decision.
  No quarantine directory in v1; that stays an extension point.

Fails closed by construction: only the guard's non-blocking floor (`warn`)
persists, so a renamed member, a future disposition or an adapter typo lands
in `rejected` rather than being guessed safe.

One bad file never aborts the run. Only three conditions fail the whole run,
and each is wrong for every file at once: an invalid `ingested_at`, a reserved
`okf_type`, and a missing inbox directory.

New code `inbox_slug_collision`: two dropped files reducing to one generated
name are BOTH refused. Persisting one would let iteration order decide the
winner, and overwriting would lose the other's content.

Phase 1 primitives are reused, never duplicated, so four helpers become
package-internal names (write_bytes, link_in_index, parse_frontmatter,
INDEX_NAME) and link_in_index learns to append to an empty index — Door A
always seeds its index with bundle_summary, but Door B has no summary to
invent and must not open with a blank line.

b7f5ce3800 feat(inbox): fail-fast on filenames over the 255-byte limit 
The slug inherited the whole filename stem with no length bound, so a long
dropped name produced a filename the filesystem cannot hold — surfacing as an
untyped OSError at the write, with an errno that differs per platform (63 on
macOS, 36 on Linux). The inbox contract promises a typed per-file outcome, so
the gate belongs in the pure function that forms the name.

Refusal, not truncation: truncating is lossy AND collision-prone — two long
names sharing a prefix would reduce to one filename and the second write would
silently claim the first file. Same posture as `inbox_slug_empty`: the library
never invents a filename the operator did not give it. The message carries the
actual size and the limit, since the fix is to rename the dropped file.

Limit verified empirically on APFS 2026-07-25: a 255-byte component writes, a
258-byte one raises errno 63. ext4 and NTFS cap at the same 255.

New MaterializationError code `inbox_slug_too_long`, registered in the errors
docstring and in the error-code conformance suite.

6b9b21c602 feat(inbox): Door B provenance render + filename slug (Phase 2 step 2) 
Second guard-independent step of Phase 2: the pure functions that turn a
dropped file's name and extracted text into an OKF concept file, with the
§7-analogous honesty marker. No runtime dependency, no guard call, no model
call — the persist gate is still steps 4–5.

- `inbox_slug(filename)` reduces a name to the Phase 1 id grammar
  (`[a-z0-9][a-z0-9-]*`): drop the final extension, lowercase, collapse every
  run of non-grammar characters to one `-`, strip the ends. A name that
  reduces to nothing fails fast rather than inventing an `untitled` fallback
  that would silently collide across unrelated files.
- `inbox_filename(slug)` namespaces it `inbox-{slug}.md`, disjoint from
  `index.md`, Door A's `ingest-*`, and `promoted-verdict-*` for every slug the
  grammar admits (asserted over a hostile-name table, not one example).
- `render_inbox_concept(...)` emits the six-key layer in fixed order — `type`,
  `title`, `source_file`, `source_sha256`, `ingested_at`, `generated: true` —
  with the digest taken over the ORIGINAL dropped bytes, never the extracted
  text, so provenance stays re-verifiable against the operator's file. Body is
  normalised to LF-only with exactly one trailing newline (dropped files
  legitimately arrive with CRLF; Door A can validate instead because it renders
  its own bodies).

Slugging normalises to NFC first. macOS (APFS) hands filenames over
decomposed, so `é` arrives as `e` + combining acute: without normalising, the
combining mark alone becomes a separator and the base letter survives
(`cafe`), where the composed form is one non-grammar character (`caf`) — one
visual filename, two slugs, depending on where the string came from. The test
pins both forms with explicit escapes so it cannot depend on the test file's
own encoding. No transliteration, deliberately: mapping non-ASCII to ASCII is
a semantic claim the slugger cannot make (Norwegian `møte`/meeting would
become `mote`/fashion). The readable name survives verbatim in `title`.

Fail-fast gates, all typed: reserved `verdict` layer refused at this door too
(the promotion gate stays the only path in); a title that is multi-line or
contains `[`/`]` refused, matching Door A's manifest rule, because it renders
verbatim into `- [title](target)`; a multi-line `source_file` refused because
line-oriented frontmatter would take the injected lines. Four new stable
MaterializationError codes, each with its entry in the test_error_codes.py
registry: `inbox_slug_empty`, `inbox_title_invalid`,
`inbox_source_file_invalid`, `okf_type_reserved`.

`ingested_at` validation moves to a shared `validate_ingested_at` in
materialize.py and is called by both doors — one rule in one place is what
keeps the determinism contract from drifting apart per door.

TDD: tests/test_inbox.py precedes the implementation. 325 tests green;
mypy --strict, ruff check/format, and the sanitize|quarantine|lexicon
boundary grep-gate clean; runtime dependencies still exactly none; the Phase 1
golden suite still passes byte-for-byte.

db93de4aef feat(extract): Door B extraction registry (Phase 2 step 1) 
First, guard-independent step of Phase 2: a stdlib-only registry mapping a
dropped file's extension to its text extractor, with the fail-fast gates that
keep binary parsing out of core. `extract_text(filename, data)` dispatches
(case-insensitively) to:

- `md`/`txt` — utf-8-sig passthrough (BOM never leaks, baseline parity with
  Door A's read_csv);
- `csv` — the Phase 1 `render_table` (renderer reused, not duplicated);
- `json` — verbatim inside `render_fenced_block`;
- `html`/`htm` — text via `html.parser`, `script`/`style` stripped, tags as
  word boundaries (spec B3: adequate for v1, richer is out of scope).

`pdf`/`docx`/`xlsx` are `[extract]`-gated; until that extra ships a parser they
fail fast with a typed error naming the extra — never a silent skip, never a
bundled parser in core. New `ExtractionError(IngestError)` carries four stable
codes (`extractor_unknown`, `extractor_extra_missing`, `extractor_decode_error`,
`extractor_empty_csv`); a non-UTF-8 file is a typed corrupt-input failure, never
a leaked UnicodeDecodeError. `extract_text` returns text content only — LF
framing and concept frontmatter are the materializer's job (step 2).

No runtime dependency and no guard call yet (the guard pin and 0.4.0 land with
the persist gate in steps 4–5). TDD: test_extract.py + the four codes in the
test_error_codes.py registry precede the implementation; mypy --strict, ruff,
and the `sanitize|quarantine|lexicon` boundary grep-gate all clean; the Phase 1
golden suite still passes byte-for-byte.

99c899f4ed docs(plan): correct Door C guard call — v0.2 has no allow_reserved kwarg 
Stage 0 guard-readiness check (this session) verified the real
`llm-ingestion-guard` v0.2.0 surface against ground truth: the Door C plan
assumed `okf.import_bundle(bundle, origin=…, channel=…, allow_reserved=False)`,
but the shipped signature is `import_bundle(bundle, *, origin, channel)` — no
`allow_reserved` parameter. Reserved-name rejection of `index.md`/`log.md` is
unconditional in the guard (OKFPathError, no toggle), so the intended default
semantics are unchanged; only the documented call was wrong and would have
raised TypeError if written verbatim. Correct the plan line before Phase 2
code is written against it.

verified before any Phase 2 code, Phase 2 split guard-independent-first,
Phase 3's configurability extracted only after two concrete consumers
exist, Phase 4 code last on a frozen contract with its coordination
started early. Connective tissue over the four per-phase plans; owns the

5aa020f4b2 feat(manifest): reject [/] in extraction title (ingest-spec §4) 
Ingest-spec §4 (ratified D1, commons bfa5a9b) requires a title to reject
`[` and `]` fail-fast at manifest load. The title is rendered verbatim into
the index link label and frontmatter (§5/§6), where a bracket would break
index-link and navigation parsing (method-spec §3 Step 1). The rule was
specced but unenforced: validation only checked single-line.

Satisfies the commons "Title link-safety" load-bearing §11 seam. Same
`manifest_schema` error code as the sibling single-line/max_rows rules;
parametrized cases added to test_manifest and test_error_codes.

3a85a4785e test(errors): pin __cause__ preservation on every fail-fast wrap 
The six `raise TypedError(...) from exc` sites (manifest.py x3, materialize.py,
connectors.py x2) turn leaked OSError / ValueError / sqlite3.Error / URLError
into typed IngestErrors while keeping the original under __cause__ — but no
test asserted the chain, so a stray bare `raise` could drop the cause
unnoticed. Add a conformance suite, one test per site, each asserting the
chained cause type. The module docstring documents the invariant. Companion
to test_error_codes.py, which pins the `.code` on the same sites.

1747238a83 fix(materialize): scope §5 replacement to the running manifest's stem 
The §3 ownership scan classified every ingest-stamped file as replaceable,
so materializing one manifest into a bundle deleted the ingest files another
manifest had stamped there — and removed their index links too.

Narrow ownership to files whose stamp names the running manifest by stem.
The stamp is `{stem}@{sha256[:16]}`; matching on the stem, not the whole
stamp, lets an edited manifest still reclaim the files a prior run of the
same manifest wrote (the stem is stable across content edits), while a
different manifest sharing the bundle keeps its own files. Implements the
trinn-e §10.2 decision. This does not close the operator-copy restriction
(a generated file copied into curated content), which stays documented in
ingest-spec.md:69-72, not enforced.

## [0.4.0] — 2026-07-25
Phase 2. The bundle inbox (Door B) and external-bundle import (Door C) ship,
and with them this library's first — and only ever — runtime dependency.
### Added
- **Door B — bundle inbox (`process_inbox`).** Per dropped file: bytes →
extraction → persist gate → render → collision gate → write → index link.
Returns an `InboxResult` whose four buckets (`persisted`, `quarantined`,
`rejected`, `failed`) are disjoint and complete, so a file that vanished
mid-run surfaces as a missing entry rather than as nothing. One bad file
never aborts the run: only an invalid `ingested_at`, a reserved `okf_type`,
and a missing inbox directory fail the whole run, each being wrong for every
file at once. Concept files are named `inbox-{slug}.md`, disjoint from
`index.md`, Door A's `ingest-*`, and `promoted-verdict-*`; `source_sha256`
is taken over the original dropped bytes, so provenance stays re-verifiable
against the operator's file.
- **Door C — external bundle import (`import_bundle`).** Reads an external OKF
bundle and hands it *whole* to an injected gate over the guard's
`okf.import_bundle` — a bundle-level call, because it resolves the
cross-link graph across concepts — merging only concepts that clear the
non-blocking floor. Two invariants, both load-bearing: a merged concept is
written **verbatim** (stamping it would require round-tripping frontmatter
through this library's line-oriented parser, which cannot represent the
block lists the guard's parser accepts, and would persist bytes the guard
never screened), and ownership is therefore proven by **content identity** —
an occupied target name is re-used only when the bytes there are already
identical, never overwritten. Re-importing an unchanged bundle is a no-op.
- **`extract_text` — the Door B extraction registry.** All file-type → text
extraction lives in this library, because the guard is text-only. `md`/`txt`
pass through, `csv` renders the markdown table, `json` is fenced verbatim,
and `html`/`htm` reduce to text with `html.parser` — stdlib throughout.
`pdf`, `docx`, and `xlsx` are gated behind the `[extract]` extra, which
ships no parser yet: those types fail fast with a typed error naming the
extra, never a silent skip.
- **`llm_ingestion_okf.guard_adapter`** — the shipped gate over the real
guard (`inbox_gate`, `import_gate`), and the only module here that imports
it. Door B screens the exact bytes it persists: the guard's `prepare_input`
bookend prepares text for a model call this library never makes, so
`screen_output` alone is used and the screened string is the written string.
It follows that the gate **refuses rather than repairs** — a file carrying
an invisible carrier is rejected, not stripped and persisted. The policy is
`PRESET_USER_UPLOAD`, so any finding at all is held back.
- **15 new stable error codes**, each registered in the `errors.py` docstrings
(the stability contract) and pinned by the error-code conformance suite:
`extractor_decode_error`, `extractor_empty_csv`, `extractor_extra_missing`,
`extractor_unknown`, `import_label_invalid`, `import_path_empty`,
`import_path_too_long`, `import_provenance_invalid`,
`import_slug_collision`, `inbox_slug_collision`, `inbox_slug_empty`,
`inbox_slug_too_long`, `inbox_source_file_invalid`, `inbox_title_invalid`,
`okf_type_reserved`.
### Changed
- **`llm-ingestion-guard>=0.2,<0.3` is now a mandatory runtime dependency.**
Installing this package installs the guard. Importing it does not: only
`guard_adapter` imports the guard, so a Door A consumer keeps working
whatever state the dependency is in, and the doors themselves still take an
*injected* gate. Until the guard is published to a package index, install it
from its tag — see the README. A packaging test enforces that this stays the
only runtime dependency.
- **An extraction `title` containing `[` or `]` is rejected at manifest load**
(ingest-spec §4, ratified D1). Previously only single-line was validated. A
manifest that loaded before and carries a bracket in a title now fails fast
with code `manifest_schema`: the title renders verbatim into the index link
label `- [title](target)`, where a bracket breaks index-link and navigation
parsing downstream.
### Fixed
- **Materializing one manifest no longer deletes the files another manifest
stamped into the same bundle.** The §3 ownership scan classified every
ingest-stamped file as replaceable, so a second manifest sharing a bundle
removed the first one's concept files and their index links. Ownership is
now narrowed to files whose stamp names the running manifest by stem — the
stem is stable across content edits, so an edited manifest still reclaims
what a prior run of itself wrote. The operator-copy restriction (a generated
file copied into curated content) remains documented, not enforced.
### Notes
- Phase 2's binary extraction is **not** in this release: the `[extract]`
extra is declared but empty, and `pdf`/`docx`/`xlsx` therefore fail fast.
That is the one outstanding item from the phase, and it ships separately.
- Exception `__cause__` preservation is now pinned by a conformance suite, one
test per fail-fast wrap site, alongside the existing `.code` suite.

### What is gated today: nothing
### What is gated today: read this before trusting a door
Door A — the only door shipped so far — is **ungated**. The package has zero
runtime dependencies and calls no guard function before writing to disk.
`materialize_bundle` writes what it is given.
- **Door A (`materialize_bundle`) is ungated.** It calls nothing before
writing to disk and writes what it is given. A caller materializing
untrusted content is responsible for gating it.
- **Doors B and C (`process_inbox`, `import_bundle`) gate through an adapter
you pass in.** Each takes a `gate` argument; the flow hands it the content
and obeys the verdict, refusing to persist anything that does not clear the
guard's non-blocking floor — including a disposition it does not recognise,
and (at Door C) a concept the gate returned no verdict for. What it cannot
do is check that your adapter is a real guard: a permissive stub approves
everything, and the flow will believe it.
If you materialize external or otherwise untrusted content, gating is **your**
responsibility at the call site: `okf.import_bundle` for received bundles, or
`prepare_input`/`screen_output` around extracted text. The guard-calling
persist gates are part of Doors B and C (phase 2), not of Door A.
`llm_ingestion_okf.guard_adapter` is the adapter over the real guard, and the
only module here that imports it — importing the package itself does not:
This is stated plainly because the earlier wording ("calls the guard at every
persist gate") described the intended end state in the present tense, and a
consumer reasonably read it as safe-by-default.
```python
from llm_ingestion_okf import process_inbox
from llm_ingestion_okf.guard_adapter import inbox_gate
result = process_inbox(inbox_dir, bundle_dir, "2026-07-25T12:00:00Z",
okf_type="reference", gate=inbox_gate)
```
Two properties of that adapter are worth knowing before you rely on it.
It screens the **exact bytes it persists** — the guard's `prepare_input`
bookend prepares text for a model call, which this library never makes, so
only `screen_output` is used and the screened string is the written string.
And it **refuses rather than repairs**: a file carrying an invisible
zero-width or bidi character is rejected, not silently stripped and written.
Door B screens under the untrusted-upload policy, so any finding at all is
held back rather than persisted.
This section is stated plainly because earlier wording ("calls the guard at
every persist gate") described the intended end state in the present tense,
and a consumer reasonably read it as safe-by-default.

Python 3.10+, and exactly one runtime dependency — the security boundary,
`llm-ingestion-guard>=0.2,<0.3`. Everything else is stdlib. Until that

pip install "llm-ingestion-guard @ git+https://git.fromaitochitta.com/open/llm-ingestion-pipeline-security.git@v0.2.0"

A git URL is a PEP 508 direct reference and pins one exact tag, so it is an
install-time *channel*, not the pin: the range above stays the declared
dependency and resolves normally once the package index exists. The optional
`[extract]` extra (pdf/docx/xlsx parsers) is not populated yet. The planned
Node half targets Node/ESM with zero npm dependencies.

# Execution order — the full roadmap, sequenced
Status: approved sequencing across all remaining phases. This doc is the
connective tissue between the per-phase plans; it owns the *order and the
reasons*, not the phase detail. Each phase's detail and verification live in its
own doc:
- `docs/plan/phase-1-door-a.md` — DONE, shipped at v0.3.2.
- `docs/plan/phase-2-doors-b-c.md`
- `docs/plan/phase-3-configurable-contract.md`
- `docs/plan/phase-4-node-half.md`
Headline order: **Stage 0 (guard gate) → Phase 2 → Phase 3 → Phase 4 code**,
with Phase 2 split guard-independent-first and Phase 4's *coordination* started
in parallel from the beginning. The quality argument for this order is below —
it is not merely the roadmap numbering.
## Stage 0 — Guard readiness (gate; do first, cheap)
Before any Phase 2 code, confirm `llm-ingestion-guard` 0.2 exists with the
pinned surface (`prepare_input`, `screen_output`, `okf.import_bundle`,
disposition enum) and is installable in CI. This is Phase 2's assumptions
B1+B2; B2 is explicitly "not yet decided", and the guard is a separate repo
(`open/llm-ingestion-pipeline-security`), so its readiness is partly outside
this repo's control.
Why first: it is the single biggest unknown, it is cheap to check (read the
guard repo), and its answer decides the *shape* of Phase 2 — run straight
through, or front-load the guard-independent half while readiness is confirmed
in parallel. Do not build a bearing dependency into the plan on an unverified
foundation. If the surface has drifted from what the plan assumes, the whole
persist-gate design must know now, not at the integration step.
Outcome recorded in STATE before Phase 2 code starts.
## Phase 2 — Doors B/C (split: guard-independent first)
Internal order follows the phase-2 doc's TDD steps, deliberately:
1. **Guard-independent half (steps 1–2):** extraction registry (stdlib core
types, fail-fast on unknown extension and on `[extract]` types without the
extra) + provenance rendering and filename slugging (pure functions). Zero
external dependency, maximal test-determinism, reuses the Phase 1 renderer.
Highest-quality-yield work to start with; validates B3 (`html.parser`
adequacy) early while it is cheap to change.
2. **Guard seam (steps 3–5):** Door B against a *stub* guard first (nail the
disposition control flow deterministically), then integration with the *real*
guard, then Door C. Stub-first means that when the real-guard integration
test is the only thing that can newly fail, a failure isolates cleanly to the
integration boundary. Door B before Door C: C reuses B's guard-gate pattern
and both reuse Phase 1 primitives.
This is where `pyproject` runtime deps become exactly the guard pin — a
semver-worthy event (propose 0.4.0), its own CHANGELOG entry.
## Phase 3 — Configurable bundle contract (only after 2)
Extract configurability only once Door A **and** Door B/C both concretely use
the type/layer/frontmatter/reserved-file constants. Phase 3 abstracts a pattern;
you need ≥2 real consumers before the right seams are visible. Building the
config object first would be speculative abstraction — an explicit anti-pattern.
The proving consumer (`claude-code-llm-wiki`, `strict-v1`) is the concrete
second profile that proves the abstraction is not single-use.
The 2→3 boundary has no painful retrofit: Phase 2 already leaves the seam open —
Door C v1 deliberately does NOT persist the guard log "because reserved-file
policy differs per consumer and becomes configurable in Phase 3." This is where
the contract becomes explicit and frozen — the precondition for a clean Node
port.
## Phase 4 — Node half (two clocks)
**Coordination clock — start early, parallel to Stages 0–3, but only the
shape-independent agreements.** Phase 4's hard preconditions are agreements, not
code: okr's reference-impl lift *in principle*, catalog as re-pin owner,
guard-as-contract at the Node persist seam, and the linkedin-studio
non-normalization carve-out can all be initiated early — via coord — so they are
settled when code starts. The one agreement that must WAIT is the exact
second-brain *contract shape*: the phase-4 doc ties the catalog-spec
expressiveness check to Phase 3's split-table step, so do not freeze the
cross-runtime contract before Phase 3 has proven the profile can express it.
**Code clock — last.** The Node/ESM implementation ports a *frozen, explicit*
contract (Phase 3's output) and uses the shared fixture suite as the
cross-runtime conformance oracle. Porting before the contract is frozen means
chasing a moving target and guaranteed drift between halves. Halves share
contract and fixtures, never code.
## Quality spine (holds across every stage)
- TDD iron law throughout: no production code without a failing test first.
- The golden/fixture suite is the backbone — every phase extends it; it is the
regression oracle and, in Phase 4, the cross-runtime conformance oracle. It
never goes non-byte-exact.
- Determinism invariant every phase (explicit `ingested_at`, LF-only,
byte-exact). Phase 2 adds: the guard *version* is part of the input surface —
pin it.
- Boundary grep-gate green every phase: `grep -rn "sanitize\|quarantine\|lexicon"
src/` empty (guard imports only).
- One phase = one release with a CHANGELOG entry; the guard dependency landing in
Phase 2 is the architectural milestone.
## Verification — the gate between each handoff
These are the objective checks that a stage is done and the next may begin:
1. **Enter Phase 2:** guard readiness recorded in STATE — either "0.2 API
matches + installable in CI" or an explicit "front-load guard-independent
half; guard integration blocked on <named item>".
2. **Phase 2 → Phase 3:** Phase 1 golden suite still byte-for-byte; `pyproject`
runtime deps == exactly `llm-ingestion-guard>=0.2,<0.3`; persist-gate proof
test green (a fail-secure fixture yields zero new files).
3. **Phase 3 → Phase 4:** golden suite byte-identical under `DEFAULT`
(`git diff --stat examples/` empty for the phase); `STRICT_V1` cross-profile
rejection tests pass both directions; split-table artifact under `docs/`
reviewed with the operator (contract is frozen and expressive enough for the
second-brain spec).
4. **Phase 4 code start:** each shape-independent coordination step has a
recorded sign-off; the contract-shape agreement is signed off *after* the
Phase 3 split-table, not before.
5. **Throughout:** `mypy --strict src/`, `ruff check .`, `ruff format --check .`
clean; boundary grep-gate empty.

(reserved-file policy differs per consumer and becomes configurable in
Phase 3).
### Settled during implementation (step 4)
- **Door B calls `screen_output` alone, and this supersedes deliverable 3's
"`prepare_input`/`screen_output` bookends".** The bookends assume a model
call between them; this library makes none, and `prepare_input` returns
prompt-shaped text (sanitized *and* spotlight-fenced with a per-call nonce)
that must never reach disk. The adapter therefore screens the extracted
text as it stands and persists that same string, so the verdict is a
statement about the bytes actually written.
- **The gate refuses; it does not repair.** Sanitizing before persisting
would write a document differing invisibly from the operator's file while
`source_sha256` still points at the original bytes. A file carrying an
invisible carrier is rejected instead — the guard's own doctrine is that a
carrier has no legitimate place in a reference file, and this library's
posture everywhere else is fail-fast, never repair. Operator decision.
- **The policy is `PRESET_USER_UPLOAD`** (untrusted tier, quarantine floor):
an inbox drop is an untrusted upload, so any finding at all is held rather
than written. A caller needing another tier injects their own adapter.
- **`guard_adapter.py` is the only module that imports the guard**, and the
package `__init__` does not import it, so a Door A consumer's import path
is unaffected by the dependency's state.
- **Assumption B1 pins what the adapters call, not the whole guard.**
`prepare_input` is dropped from the smoke test: drift there cannot reach
this library. What is pinned: `screen_output` and `okf.import_bundle`
signatures, the `Disposition` values both doors compare against, the
`Origin`/`Channel` vocabularies Door C validates, the result fields the
adapters read, and the upload preset's shape.
- **The pin stays a range; the git URL is an install channel.** A PEP 508
direct reference pins one tag and cannot express `>=0.2,<0.3`, but it is an
install-time channel rather than a dependency declaration: the range is
what `pyproject.toml` carries, it is satisfied by the tag install today,
and it resolves normally once the package index exists (confirmed by the
guard repo, superseding an earlier reading that the range had to go).
- **Door C reasons are derived, not carried.** The guard's `stamp_concept`
keeps a concept's disposition and drops the reason strings behind it, so
the adapter reports `severity:label` per finding — the audit trail actually
available at that seam.
### Settled during implementation (step 5)
- **Verbatim merge, no frontmatter of ours.** A merged concept is written
exactly as the gate saw it. This is a correctness constraint, not a
preference: the guard's frontmatter parser accepts block lists, which this
library's line-oriented `parse_frontmatter` cannot round-trip, so stamping
provenance into an external concept would silently drop sender data — and
would persist bytes the guard never screened.
- **Ownership by content identity.** With no stamp available, an occupied
target name is re-used only when the bytes already there are identical (a
no-op re-merge, so re-import of an unchanged bundle is idempotent).
Anything else at the name — curated content or an updated version of the
same concept — is refused under `collision_unstamped`; the operator removes
the file to accept an update. A configurable stamping/reserved-file policy
is Phase 3's.
- **The merge floor is fail-closed, not "no error".** Deliverable 1's wording
is the looser reading: a concept carrying no error but a FAIL_SECURE or
unrecognised disposition is refused, and a concept the gate returned no
verdict for at all is refused. Only the guard's non-blocking floor merges —
the same floor Door B applies, with `quarantine_review` reported as its own
bucket rather than folded into rejection.
- **Upstream has already moved past the pin (observed, not acted on).** The
guard's `main` carries a commit that adds `allow_reserved=True` to
`okf.import_bundle` and *scans* `index.md`/`log.md` in a mode-b import
instead of path-rejecting them. The pin is the `v0.2.0` tag, where the
kwarg does not exist and rejection is unconditional, so this door is built
against the tag. Whoever bumps the pin owns re-checking that branch: today
a reserved name in a received bundle arrives as a per-concept rejection.
- **`origin`/`channel` are validated against the guard's pinned vocabulary.**
The guard derives trust from `origin` by enum *identity*, so an unrecognised
string would be silently downgraded to untrusted. The library refuses to
carry a provenance declaration it cannot recognise rather than let a typo
decide trust — refusing to guess, not deciding trust itself.
## Design decisions fixed by this plan

"""The only module in this library that imports `llm-ingestion-guard`.
Doors B and C take an INJECTED gate so the flows stay dependency-free and
testable; this module is the adapter a caller injects when the gate should be
the real guard. It translates in one direction only — guard verdict in, the
door's decision type out — and takes no decision of its own. Everything a
verdict depends on happens inside the guard.
**Door B screens the exact bytes it persists.** The guard's §6 bookends
(`prepare_input` -> model -> `screen_output`) assume a model call in between;
this library makes none, and `prepare_input` returns prompt-shaped text
(sanitized AND spotlight-fenced with a per-call nonce) that must never reach
disk. So the adapter calls `screen_output` alone, on the extracted text as it
stands, and hands that same text back. Two consequences, both deliberate:
- an invisible carrier is REFUSED rather than stripped-and-persisted. The
guard's own doctrine is that a carrier has no legitimate place in a
reference file, and sanitizing before persisting would write a document
that differs invisibly from the operator's file while `source_sha256`
still points at the original bytes. This library validates and refuses;
it does not repair.
- the verdict is a statement about the persisted document, because the
screened string and the written string are the same string.
The policy is `PRESET_USER_UPLOAD`: an inbox drop is an untrusted upload, so
any finding at all is held for review rather than written. A caller who needs
another tier writes their own three-line adapter — that is what the injected
seam is for.
**Door C hands the bundle over whole.** `okf.import_bundle` resolves the
cross-link graph across concepts, so gating them one at a time would throw
half the gate away. The adapter maps each `ConceptResult` to an
`ImportDecision` and returns the guard's log body unwritten.

"""Door C: external bundle import — read, gate per concept, merge the accepted.
A third-party OKF bundle is read as `{bundle-relative path -> document text}`,

resolves the cross-link graph across concepts, so gating them one at a time
would throw that half of the gate away), and only concepts whose verdict clears

A merged concept is written VERBATIM — exactly the text the gate saw. Nothing
of this library's is merged into its frontmatter, and that is a correctness
constraint, not a preference: the guard's frontmatter parser accepts block
lists, which this library's line-oriented :func:`parse_frontmatter` cannot
round-trip, so re-rendering a concept would silently drop data the sender
supplied. It would also persist bytes the guard never screened.
That leaves ownership to be proven by content identity instead of by a stamp:
a target name held by byte-identical content is a no-op re-merge (so re-import
of an unchanged bundle is idempotent), and a target name held by anything else
is refused. Curated content and an UPDATED external concept are refused alike —
the library cannot tell them apart without a marker it has no safe place to
write, and refusing is the answer that never destroys. A configurable
reserved-file/frontmatter policy is Phase 3's; this is the v1 floor.

`source_file`, `source_sha256`, `ingested_at`, `generated: true`).
`source_sha256` is taken over the ORIGINAL dropped bytes, never over the
extracted text, so provenance stays re-verifiable against the operator's file.
`ingested_at` is explicit and validated by the same rule as Door A: no
wall-clock anywhere. Output is LF-only with exactly one trailing newline.
`process_inbox` is the flow: per file, extracted text goes through the guard
gate before anything is written, and only the gate's non-blocking floor
persists. No model call anywhere, and no security decision here — the gate
supplies the verdict and this module only obeys it.

"""Exception chaining: every fail-fast wrap preserves its `__cause__`.
The library turns leaked stdlib failures (OSError, ValueError, sqlite3.Error,
URLError) into typed IngestErrors at the boundary — but always with
`raise TypedError(...) from exc`, never a bare `raise`. That `from exc` keeps
the triggering exception under `__cause__`, so an operator reading a traceback
still sees the underlying cause (which file, which OS error, which SQL fault)
beneath the typed message. This file IS the conformance suite for that
invariant: one test per `raise ... from exc` site, asserting the chained type.
Companion to test_error_codes.py, which pins the `.code` on the same sites.

"""Doors B and C against the REAL `llm-ingestion-guard` (Phase 2 step 4).
Steps 3 and 5 exercised the flows against test doubles; this suite wires the
pinned dependency in and pins two different things:
- **the surface (assumption B1).** `test_guard_*` reads the guard's actual
signatures, enum values and result fields, and compares them against the
constants the library branches on. These tests are the upgrade-drift alarm:
they fail when the dependency moves under us, which is the only way a
by-value comparison (`"warn"`) can be kept honest without importing the
enum into the flow modules.
- **the behaviour.** A benign fixture persists; a fixture the guard fails
secure on leaves the bundle byte-identical. Verdicts here come from the
real scanner, so these are the tests that would notice the adapter passing
the wrong text, the wrong policy, or the wrong direction of the branch.
The adapters are deliberately thin, and that is the point: everything a
verdict depends on happens inside the guard.

"""Door C import flow against a stub import gate (Phase 2 step 5).

What the flow owes the caller, and what this suite pins:
- the guard decides per concept; the library only branches on the verdict and
never re-derives one (an unrecognised disposition, and a concept the gate
returned no verdict for, must both fail CLOSED);
- a merged concept is written VERBATIM — exactly the text handed to the gate,
with no frontmatter of ours merged into it (round-tripping the concept's own
frontmatter through this library's line-oriented parser would silently
destroy the block lists the guard's parser accepts);
- ownership is proven by content identity, not by a stamp: a target name held
by identical bytes is a no-op re-merge, and a target name held by ANYTHING
else is refused — curated content and a changed external concept alike;
- one bad concept never aborts the run;
- the guard's log body is returned to the caller, never persisted (the
reserved-file policy is Phase 3's).

"""Door B inbox flow against a stub guard (Phase 2 step 3).
The stub stands in for the pinned `llm-ingestion-guard` surface so the persist,
quarantine and reject branches run deterministically without the dependency
installed. It is a TEST DOUBLE and lives here on purpose — never in `src/`.
What the flow owes the caller, and what this suite pins:
- the guard decides; the library only branches on the verdict and never
re-derives one (an unrecognised disposition must fail CLOSED);
- what is persisted is the guard's SANITIZED text, so the bytes screened at
the gate are exactly the bytes written;
- one bad file never aborts the run — every per-file failure is reported and
the remaining files still process;
- the collision gate runs before any mutation and never overwrites curated
content, exactly as at Door A.
