fix(security): use security@ as the reporting contact, not hello@

hello@ works, but two different addresses across sibling org repos
force a reporter finding a vulnerability to guess which one is the
security channel. security@fromaitochitta.com is the designated one.

+  versjonen som er pinnet, og re-pinning er en egen release. Mot en TREDJEPARTS-implementasjon
+  av samme tabell gjelder §7 uendret. Til og med `v0.8.1` sto regelen uskopet. Se
+  `spec/conformance-corpus.md` §7.1.
+- **En case er ikke mintbar uten inngangspunkt for sitt scope.** Korpuset pinner ikke
+  lenger ett inngangspunkt per runtime for alt — `manifest.json` →
+  `entry_points_by_scope` bærer inngangspunkt, **findings-accessor** og
+  **fixture-presentasjon** per scope per runtime. En runtime hvis flate er sti-basert kan
+  ikke måle en løs `input.txt`, og en fixture den får som løs tekst måler ingenting
+  samtidig som den ser ut som en pass. Nytt scope ⇒ fyll ut alle tre FØR første case.

+  fixturene tilbake fra disk og utleder alt på nytt (digest, id fra case-id, scope,
+  exact-within-scope). Ligger i scratchpad, aldri i repoet.
+- **En innsnevring måles mot HELE korpuset, ikke mot casene den handler om.** Endrer en
+  oppdatering hva en runtime *slutter* å rapportere, kan den tømme et `observed_out_of_scope`
+  hvor som helst — også på caser scopet til en helt annen tabell. Det feltet er evidens
+  (spec §5), så **ingen testsuite noe sted vokter det**: en foreldet oppføring består hver
+  kjøring for alltid. Kjør hver committet case gjennom sitt eget scopes inngangspunkt og
+  sammenlign mot BEGGE stedene fixturen fører en runtime-label — `findings` (mappet via
+  tabellens aliases) og `observed_out_of_scope`. Målt 2026-08-13: seks «åpenbare» caser
+  flyttet seg ikke, én lexicon-case gjorde det.
+- **En foreldet residue-oppføring skrives ikke om — den pinnes.** `observed_out_of_scope` er
+  sann ved commiten `measurement` pinner. Retter du én av 83, står 82 målinger ved én commit
+  og én ved en annen, under en header som navngir én. Før avviket i manifestet med dato og
+  commit i stedet. Å re-pinne hele korpuset er en egen beslutning.
+- **Like funn-sett betyr ikke lik feilflate.** Spørsmålet som avgjør om en variant-case skal

+  inputen kan FEILE, innenfor scope, under en endring i den scopede datafila som den første
+  ville bestå. Korpusets første variant forventer nøyaktig samme funn som base-casen og
+  gater likevel noe base-casen ikke ser: base-inputen matcher mønsteret både i publisert og
+  i tidligere, strengere form. En payload hvis skille ligger i en tabell vi ikke publiserer
+  består ikke terskelen og føres som navngitt utelatelse. Spec §6 bærer regelen.
+
+### Id-rom: adoptert vs. navngitt
+
+Standard er **adopsjon verbatim** fra en runtimes egne labels (leksikonets 83, active
+contents 6). Å NAVNGI en id her er unntaket og krever at begge runtimes er spurt først —
+`carrier:*` er den eneste så langt, og `carriers.json` bærer begrunnelsen.
+
+To regler som ikke er utledbare fra dataene:
+
+- **Et prefiks som bare betyr noe inne i én runtime kan ikke bære et DELT id-rom.** Guarden
+  korrigerte oss selv på at «prefiks == `detector`-feltet» gjelder seks carrier-labels og

+# Conventions
+
+The rules a change to this repository is held to, in one place.
+
+Nothing here is new policy. Every rule below was already being applied — some of it stated in
+[README.md](README.md), some in [SECURITY.md](SECURITY.md), some only visible in the shape of
+the files themselves. It is collected here because a convention that only exists in the
+maintainer's head is not a convention an outside reader can meet, and because two of the
+decisions this repository makes — that nothing here runs, and that pull requests are switched
+off — look arbitrary until the reason is written down next to them.
+
+This file binds **contributions to this repository**. It does not bind the runtimes that read
+the data; that is what `spec/` is for, and those files say `Status: normative` and mean it.
+
+## The charter: nothing here runs
+
+**This repository contains no executable code, and it will not acquire any.**
+
+Not permitted, without exception:
+
+- `.mjs`, `.js`, `.ts`, `.py`, `.sh` — or any other file that implements detection, scanning,
+  normalisation, scoring or I/O;
+- `package.json`, `pyproject.toml`, lockfiles, dependencies, build steps;
+- an import of, or knowledge of, any framework, SDK or runtime;
+- network access, model calls, dependence on the clock, or randomness.
+
+Permitted: JSON data, normative specifications in Markdown, and conformance fixtures
+(`input.txt` plus `expected.json`).
+
+The reason is `fork-and-own`. A consumer on a runtime nobody here has thought of should be able
+to vendor this repository without inheriting a single technology choice. A build step is a
+technology choice; so is a test runner. The moment one exists, the set of runtimes that can
+adopt this core shrinks to the set that tolerates it.
+
+The consequence is that **this repository cannot validate itself**. There is no CI in this
+organisation and nothing runs on push. The checks below are yours to run, and they are the only
+ones there are.
+
+## How a change gets in — and why not by pull request
+
+Pull requests are switched off on the canonical repository at
+`git.fromaitochitta.com/open/llm-security-commons`, and issues are not the reporting channel
+either. That is deliberate, and the reason is stronger than a preference about tooling.
+
+This repository is **vendored into independent runtimes** — a Claude Code plugin on Node/ESM, a
+Python guard, an advisory surface — each pinning a tag. The contract between them is semver, and
+a change to detection data changes what those runtimes *find*. A patch to a pattern table is not
+a contribution that can be merged and then socialised; it is a contract change that has to be
+coordinated with every consumer **before it exists**, because the moment it is tagged, the next
+consumer to pull it gets different findings than the one that pulled yesterday. A merge button
+does not do that, and nothing downstream of a merge button can.
+
+So the routes in are:
+
+1. **Fork and own it.** MIT, and an intended use rather than a tolerated one. If you need a
+   different value in your runtime, this is the fast path and it is fully supported.
+2. **Report it privately** — see [SECURITY.md](SECURITY.md). A wrong entry in a detection table
+   is a silent false negative in every runtime that reads it, so a report about one is a
+   security report even though nothing here executes. That file also explains why a confirmed
+   defect in extracted data is usually decided in the runtime it came from before it changes
+   here.
+
+If you maintain a consumer, the coordination channel is direct contact with the maintainer, not
+this repository's forge surface.
+
+## Data files (JSON)
+
+- **Every JSON file carries a top-level `"version"`** — a semver string. No exceptions.
+- **Every JSON file states what it is and where its data came from**, in a top-level
+  `"$comment"` or `"description"`. Provenance is not optional metadata here; it is what makes
+  the difference between a table and a rumour.
+- 2-space indentation, LF line endings, a trailing newline, UTF-8 without BOM.
+- **Code points are written as strings** — `"U+200B"` — never as the raw invisible character.
+  Review cannot see what it cannot render, and a reviewer who cannot see a character cannot
+  check it. The single exception is `conformance/*/input.txt`, which by definition contains the
+  actual bytes.
+- **Keys are stable identifiers.** Consumers match on them. **Changing a key is a breaking
+  change** and is versioned as one.
+
+The four files that carry detection material — `codepoints/carriers.json`,
+`signatures/secret-egress.json`, `signatures/malware-signatures.json`,
+`signatures/active-content.json` — take one further rule, which is the most important line in
+this document:
+
+> **They are changed only from verified source data** — a dump from the owning repository, the
+> Unicode standard, published vendor documentation. Never from memory, never "filled in for
+> consistency". A guessed code point or a regex with wrong escaping is a silent false negative:
+> a detector that looks like it is working and is not looking. If an entry cannot be verified,
+> leave it out, or mark it explicitly unverified in its `$comment`.
+
+## Specifications (Markdown)
+
+- A normative specification carries **`Status: normative`** at the top and uses RFC 2119 terms
+  (MUST / MUST NOT / SHOULD / MAY) in uppercase, deliberately. These files bind the
+  implementations that read them.
+- An informative document (`docs/`) carries **`Status: informative`** and is **never ground
+  truth**. It records measurements, history and open disagreements; a runtime is not wrong for
+  disagreeing with one.
+- Naming a file that does not exist yet is allowed where the layout is part of the contract —
+  `spec/decode-pipeline.md` is named in README.md and marked **Planned**. It is not a link, and
+  nothing depends on it. A normative spec guessed at would be worse than an absent one.
+
+## Conformance cases
+
+- One directory per case: `conformance/<case-id>/input.txt` and
+  `conformance/<case-id>/expected.json`.
+- `<case-id>` is stable and descriptive. **Changing a case id is a breaking change** — a
+  published conformance result names it.
+- `expected.json` is **ground truth**. If a runtime disagrees with it, the runtime is wrong.
+- One way that reverses: the fixture is proven wrong. Then the fixture changes **in its own
+  commit, with the reason written down** — never folded into a change that does something else,
+  because a fixture edit is the one edit that can make every conforming runtime wrong
+  identically.
+- The other, added in `v0.9.0`: where a case's scope is a table only one runtime implements and
+  that runtime authored the payload, a divergence by **that** runtime is neither a proven-wrong
+  fixture nor necessarily its bug. The fixture is not rewritten on the divergence alone — it is
+  recorded against the version pinned, and re-pinning is a separate release. Through `v0.8.1`
+  this list carried only the first way. See
+  [`spec/conformance-corpus.md` §7.1](spec/conformance-corpus.md).
+- A case declares the data files it is `scope`d to. A runtime that does not implement a scoped
+  table reports the case `not-applicable` — a third verdict beside pass and fail, and one that
+  must be reported rather than dropped from the denominator. See
+  [`spec/conformance-corpus.md`](spec/conformance-corpus.md).
+
+## When a value may change
+
+Detection values do not change here because someone here judged them wrong. Three mechanisms
+have moved a value so far, and each is recorded in the file itself rather than only in the
+changelog:
+
+1. **Re-extraction** — the owning runtime changed its own value, and this repository re-read the
+   source at a pinned public commit. Recorded in `source_fidelity.post_extraction_drift`.
+2. **Retraction** — this repository described its own provenance wrongly. The stored value may
+   have been right all along; the account of where it came from was not. Recorded in
+   `source_fidelity.retracted`.
+3. **Owner-directed authoring** — the owning runtime decided a value and asked this repository
+   to carry it, because the dependency has inverted: the source now reads *this* file and holds
+   no literal to re-read. Recorded separately, in `source_fidelity.owner_directed_changes`,
+   precisely because calling it drift would assert that the source moved and commons followed —
+   which would be false in the one direction that matters.
+
+What is **not** on that list is merit. Data extracted from an implementation is kept
+behaviour-identical to it on purpose, because a copy that disagrees with its source is the exact
+failure this repository exists to prevent. Producing one as a *fix* would be self-defeating. If
+you believe an extracted value is wrong, say so — and expect the decision to be taken in the
+runtime where the pattern is under test.
+
+Data **authored here** rather than extracted — conformance payloads, flagged as
+`authored_payloads` in `conformance/manifest.json` — is this repository's own to correct.
+
+## Versioning
+
+Two version numbers, and they are not locked to each other:
+
+- **The repository tag** (`vX.Y.Z`) versions **the contract**: the file set, the key names, the
+  case ids, the disposition semantics.
+- **Each JSON file's own `"version"`** is bumped when *that file* changes.
+
+What counts as which:
+
+| Change | Bump |
+| --- | --- |
+| New data field, new entry | minor |
+| Changed or removed key, case id, or layout | **major** — consumers break |
+| A change to what a conforming runtime *finds* | minor in 0.x, and the changelog says so |
+
+That last row is why **the changelog entry is the thing to read before upgrading, not the
+version number**. Pre-1.0, a release that changes findings is still a minor bump; only the entry
+tells you whether your assertions move.
+
+Consumers vendor **a tag, never `main`** — a conformance result can only be attributed to a tag.
+Nothing polls for updates; when a change moves detection data, the maintainer notifies known
+consumers directly, and their upgrade remains their own action on their own schedule.
+
+## Checks to run before proposing a change
+
+There is no CI. These four are the validation surface, they run offline in a second, and each
+one has been confirmed to go red on a violation rather than merely green on a clean tree.
+
+```bash
+# 1. Every JSON file is well-formed
+find . -name '*.json' -not -path './.git/*' -print0 \
+  | xargs -0 -n1 python3 -m json.tool > /dev/null && echo OK
+
+# 2. Every JSON file outside conformance/ carries a top-level "version"
+find . -name '*.json' -not -path './.git/*' -not -path './conformance/*' -print0 \
+  | xargs -0 python3 -c 'import json,sys
+missing=[p for p in sys.argv[1:] if "version" not in json.load(open(p))]
+print("\n".join("MISSING version: "+p for p in missing) or "OK")'
+
+# 3. Every spec carries its normative marker (prints offending files, nothing = clean)
+grep -L 'Status: normative' spec/*.md || echo OK
+
+# 4. Charter guard: no executable code has crept in
+find . -type f \( -name '*.mjs' -o -name '*.js' -o -name '*.ts' -o -name '*.py' -o -name '*.sh' \) \
+  -not -path './.git/*' | grep . && echo 'CHARTER VIOLATION' || echo OK
+```
+
+They are written as shell one-liners rather than shipped as a script because a script would be
+`.sh`, and check 4 would then fail on the tooling meant to enforce it.
+
+What they do **not** check: whether a value is *correct*. Nothing offline can. That is what the
+conformance corpus is for, and it runs in each consumer's own test suite against a pinned tag —
+constraining two of the seven data files, which is a real limit and is stated in
+[README.md](README.md) under **Known limitations**.

+- `signatures/active-content.json` — 7 cases, one per published id, the seventh added in

+  runtime declares which commons data files it implements, and a case scoped outside that
+  set was never addressed to it. See [§1.1](spec/conformance-corpus.md) — and note that
+  `not-applicable` says the corpus did not ask, never that the runtime is blind.
+- `codepoints/carriers.json` — 3 cases, added in v0.5.0. **Both** runtimes implement these
+  tables; only one has published a label for the finding. So these three are `not-applicable`

+
+One case remains unshipped, for the secret-egress table, and it is not blocked on effort. The
+reasons are three, they were measured, and they are independent — none of them dissolves under
+anything this repository can run alone. **(1) There is no id space on the commons side.** The
+seed this table was ported from carries a name and a pattern per entry and nothing else, so its
+entries are keyed by human-readable name while the other runtime emits `egress:<id>` labels —
+and a fixture names labels. This is the hard blocker, and the only one of the three that an
+answer can resolve; the answer belongs to the runtimes that own the seeds, not to a name coined
+here. **(2) Match semantics disagree**, and an id space would not close it: this table declares
+first-match-wins with `ordering.normative: true`, the other runtime reports every match, and one
+witness — an `Authorization` header holding a three-part JWT — produces one label here and two
+there. That difference is exactly what an `expected.json` encodes. **(3) Membership diverges in
+both directions, and the divergence is inherited rather than introduced.** The two sides hold 19
+entries and 25, but they are ports of two *different* source tables in one source repository, so
+re-measuring either port cannot close it. `conformance/manifest.json` records all three under
+`scope_planned.blockers`, and the method behind every number is in
+[the divergence measurement](docs/secret-egress-divergence.md).
+
+The carrier blocker closed in v0.5.0 and is kept, with its retired text, under
+`scope_planned.blockers_resolved` — including the correction one runtime volunteered against
+a general rule this repository had written down and should not have.

+## Contributing
+
+[CONVENTIONS.md](CONVENTIONS.md) is the whole rule set a change here is held to: the charter
+(nothing runs, and why that is load-bearing rather than fussy), the file conventions, when a
+detection value is allowed to move, how the two version numbers work, and the four offline
+checks that stand in for the CI this organisation does not have.
+
+It also answers the question the forge surface raises on its own: **pull requests are switched
+off, deliberately.** This repository is vendored into independent runtimes that pin a tag, so a
+change to detection data changes what they *find* — that has to be coordinated with each
+consumer before it exists, which a merge button cannot do. Fork-and-own is the supported path;
+a wrong entry is reported privately.
+
+## Reporting a wrong entry
+
+A wrong code point or a mis-escaped regex here is a silent false negative in every runtime
+that reads it, so it is a security report even though nothing runs. Send it privately — see
+[SECURITY.md](SECURITY.md), which also explains why a confirmed defect in extracted data is
+decided in the runtime it came from before it is changed here.

+# Security policy
+
+This repository ships **no runnable code** — no package, no build, no dependency tree,
+nothing that executes on your machine. So the usual question, *can this be exploited*,
+has an unusual answer here: the attack surface is the **data**.
+
+Seven data files here carry the detection material — pattern tables, code-point carriers,
+calibration thresholds, an OWASP mapping — and several independent runtimes read them at the
+same time. A wrong code point, a mis-escaped regex, a fixture that expects a miss: none of that
+crashes anything. It produces a detector that looks like it works and is not looking. That
+is the vulnerability class this policy is about, and a report of one is welcome even though
+no code changes as a result.
+
+## Reporting
+
+**Do not open a public issue.** A report here usually names an input that gets *past* a
+detector, and that is a working bypass against every consumer until it is closed.
+
+Report privately by email:
+
+- **security@fromaitochitta.com**, with `SECURITY` at the start of the subject.
+
+Pull requests are not the channel either — they are switched off on the canonical
+repository, and not as an oversight. This repository is vendored into independent runtimes
+that pin a tag; a change to detection data changes what those runtimes *find*. Such a change
+has to be coordinated with each consumer before it exists, which a merge button does not do.
+Fork-and-own is the supported path.
+
+Please include:
+
+- the file and the entry — its `name`, `order` or `id`, whichever that file uses;
+- the tag you read (`v0.3.0`, not "main");
+- the input that should have matched and does not, or the input that matches and should not;
+- what a consuming runtime actually does today, if you have measured it.
+
+**Obfuscate live payloads.** Do not send a working credential or a live carrier. Spell
+invisible characters as code points the way the tables do (`"U+200B"`), and use placeholder
+key material — a report should not itself be a delivery mechanism.
+
+## What counts as a vulnerability here
+
+In scope — all of these are real reports:
+
+1. **A detection entry that is a silent false negative.** A wrong code point, a regex whose
+   escaping is wrong for the declared dialect, missing or wrong flags, a pattern that fails
+   to compile in a documented engine and gets skipped rather than reported.
+2. **A conformance fixture that sanctions a miss.** `expected.json` is ground truth: a
+   runtime that disagrees with it is deemed wrong (as scoped by `spec/conformance-corpus.md`
+   §7.1, which narrows who that reaches and not this direction). A fixture that expects too
+   little makes every conforming runtime wrong identically, and the corpus will not catch it.
+3. **A normative clause that mandates unsafe behaviour.** The `spec/` files bind the
+   implementations that consume them, so a weak rule propagates to all of them.
+4. **A real secret or personal data in the repository or its history.** The history is
+   public in full.
+5. **Data that has gone stale against its declared source in a way that under-detects.**
+   Each data file names its source in a `provenance` block. If that source has since added
+   or corrected an entry, the copy here under-matches, and a consumer vendoring it is less
+   protected than the runtime it was taken from.
+
+Out of scope — documented boundaries, not vulnerabilities. See **Known limitations** and
+**Non-goals** in [README.md](README.md):
+
+- a detection class absent from the tables entirely (coverage is the union of what the seed
+  implementations detected, not of what exists);
+- a table implemented by only one runtime, and cases marked `not-applicable` for the others;
+- disagreement about a `calibration.json` threshold — the thresholds are published, the
+  policy built on them belongs to the consumer;
+- a divergence already recorded in [`docs/lexicon-port-divergence.md`](docs/lexicon-port-divergence.md);
+- the five data files no fixture constrains, and the finite homoglyph map.
+
+If you are unsure which side something falls on, report it privately anyway.
+
+## Why a confirmed defect is usually not fixed here first
+
+This is the part that differs from an ordinary repository, and it is worth reading before
+you conclude that a fix is being stalled.
+
+Most data here is an **extraction**: a copy of a table that lives in a runtime, kept
+behaviour-identical to it on purpose. Correcting an entry here — even a genuinely wrong one
+— would make the copy disagree with the implementation it was taken from. Two implementations
+answering differently on the same input is precisely the failure this repository exists to
+prevent, so producing one as a *fix* would be self-defeating.
+
+A confirmed defect in extracted data therefore travels:
+
+1. the report reaches the maintainer here, privately;
+2. the owning runtime is identified — every data file names it in `provenance.source_repo`
+   — and the report is routed there;
+3. the decision is taken **there**, where the pattern is under test against a real suite;
+4. once the source has moved, this repository **re-extracts** from a pinned public commit
+   and tags a release;
+5. consumers pull that tag on their own schedule.
+
+Stated plainly, because it affects you: fix latency is bounded by the owning runtime's
+schedule and by each consumer's pull, not by this repository's. If you need protection
+sooner than that, the fix belongs in your own runtime; this repository is where it becomes
+shared, not where it becomes real.
+
+Two things do **not** take that route:
+
+- **A real secret in the repository or its history** (class 4) is handled here, immediately.
+- **Data authored in this repository** rather than extracted — it is flagged as such where
+  it occurs, for example `authored_payloads` in `conformance/manifest.json` — is this
+  repository's own to correct.
+
+The precedent is on the record. In `v0.3.0` a detection pattern changed value here for the
+first time, and it changed because the owning runtime had changed its own and this
+repository re-read the source — not because a reviewer here judged the old value wrong.
+`docs/lexicon-port-divergence.md` records a row where two runtimes still disagree and this
+repository deliberately did *not* pick a winner. Provenance is the ground for moving a
+value. Merit is not, and the day it becomes the ground, the guarantee is gone.
+
+## Supported versions
+
+Pre-1.0. Only the latest tag is fixed; there are no back-ported branches.
+
+Consumers vendor this repository (`git subtree`, or a pinned copy) rather than installing
+it, so a fix reaches a consumer only when that consumer pulls the new tag. There is no CI in
+this organisation and nothing polls for updates. When a fix changes detection data, the
+maintainer notifies the known consumers directly — but their upgrade is their own action, on
+their own schedule.
+
+Read the `CHANGELOG.md` entry before upgrading rather than the version number: in 0.x, a
+change to what a conforming runtime *finds* is still a minor bump.
+
+## Disclosure
+
+There is no formal embargo SLA here. The maintainer will acknowledge the report, agree a fix
+and disclosure timeline with the reporter, and credit the reporter in the `CHANGELOG.md`
+entry unless they prefer to remain anonymous.
+
+If the report is a false negative in a table that has already shipped, the changelog entry
+will say what slipped through, in enough detail that a consumer still pinned to the older
+tag can judge whether it is exposed. Naming it is the point of fixing it.

+
+At the time this file was written, `<script>alert(1)` (unclosed) and `<script src=x.js>` were
+commons misses only in the sense that commons was a byte-identical extraction of
+`llm-security`, so "commons misses" meant "commons and `llm-security` both miss, the guard
+does not." That symmetry broke on `llm-security`'s side.
+
+`llm-security` commit `90f576f` (`fix(llm-security): v8.x-A - close <script> recall hole, add
+whole-table ReDoS gate`) replaced the source pattern
+
+```
+<script\b[^>]*>[\s\S]*?<\/script>
+```
+
+with
+
+```
+<script\b[^>]*>
+```
+
+dropping the closing-tag requirement that produced the recall hole this file first measured.
+Both witnesses now match on `llm-security`'s side. Verified directly against the module at
+commit `c67bad3` (2026-08-10, first commit carrying the change) and re-confirmed unmoved at
+`b1ba1fb` (2026-08-11, current public-remote HEAD as fetched this session) — `git diff
+c67bad3..b1ba1fb -- scanners/lib/injection-patterns.mjs` is empty, so no later commit touched
+the pattern a second time.
+
+The guard's pattern was never the same construct: `<script\b[^><]*>`, negated-class excluding
+both `>` and `<` (`src/llm_ingestion_guard/injection_lexicon.json:463`, unchanged since
+`de09711`, re-confirmed unmoved through current guard HEAD `0dce50f`, 2026-08-11). The two
+patterns now agree on **shape** — both drop the closing-tag requirement, both are a single
+negated-class run immediately after `<script\b` — but they are still not byte-identical: the
+guard's excluded-character class also excludes `<`, `llm-security`'s does not. That one-byte
+difference is unresolved on both sides (see *Open questions* in the coordination thread); it
+does not reopen the closing-tag question, which is settled.
+
+**Commons converged in lexicon `0.7.0` (2026-08-11), and this row is closed on the closing-tag
+axis.** Through `0.6.0` commons was the sole diverger of the three: both `llm-security` and the
+guard matched `<script src=x.js>` and unclosed `<script>alert(1)`, and commons' extracted pattern
+still required `</script>`. Commons now carries `<script\b[^>]*>` — byte-identical to
+`llm-security`'s `RegExp.prototype.source` at `b1ba1fb`, verified by compiling both.
+
+The decision was **re-extraction, not revision**, and the distinction is what made it available
+at all under the behaviour-preservation invariant. That invariant forbids commons from correcting
+seed data it believes is wrong; it does not forbid re-reading the source after the source itself
+moved and its owner asked. The lexicon's declared provenance is `llm-security`'s injection table,
+and being loadable verbatim by that table's owner is the one thing it exists to do — the standing
+alternative was a per-pattern override in `llm-security`'s own loader, i.e. a published core that
+its source repository could not load as published. Operator decision, 2026-08-11, on
+`llm-security`'s blocking coord request. Explicitly **not** decided by the 2-of-3 majority: a
+count of implementations is not a mandate over detection data, and the provenance argument would
+have held with the guard on either side.
+
+The direction matters for what it cannot break: the new form matches a strict superset of the old
+one, so relative to `0.6.0` it can add matches and cannot add a false negative. The reverse change
+would not have been adoptable on the same reasoning.
+
+**The one-byte span difference is CLOSED as of commons `0.8.0`** — all three runtimes now carry
+`[^><]*`. What follows is the account of the divergence while it was open, kept because the table
+below is the measurement that made the closure decidable, and because a consumer diffing against
+`v0.3.0` will find the two changed rows and needs the coordinate.
+
+While it was open, the guard excluded `<` from its negated class and the other two did not. The
+three forms turn out to be **totally ordered by what they match** — each a strict superset of the
+next:
+
+| Witness | commons `0.7.0` / `llm-security` `[^>]` | guard `[^><]`, and commons from `0.8.0` | commons ≤ `0.6.0` |
+| --- | --- | --- | --- |
+| `<script>steal()</script>` | match | match | match |
+| `<script src=x.js>` | match | match | no match |
+| `<script>alert(1)` | match | match | no match |
+| `<script\n  src=x>` | match | match | no match |
+| `<script a="<" >x` | **match** | **no match** | no match |
+| `<script<div>` | **match** | **no match** | no match |
+
+Measured by compiling all three forms, not reasoned from the character classes. The last two rows
+are the whole residual divergence.
+
+The witness set and the ordering observation are `llm-security`'s, from their coord message of
+2026-08-11T11:01:59Z; both were **reproduced here independently** before being recorded, including
+the strict-superset property in both directions. Their reading of it: `[^><]` refuses to cross a
+`<`, and since anything that reaches `[^>]`-and-not-`[^><]` already contains a literal `<script`
+opening tag, the narrower class buys an empty false-positive surface in exchange for two dropped
+input classes — a recall loss with no precision gain to trade for.
+
+**That argument is recorded, not endorsed, and it did not decide commons' form.** Commons carries
+`[^>]` because the lexicon's declared provenance is `llm-security`'s table (see above), not
+because their regex won on merit — the same reasoning would have taken commons to `[^><]` had the
+source been the guard's. `llm-security` asked to hear the guard's reason for `[^><]` — a ReDoS
+bound, or a span-extraction consumer needing the run to stop at `<` — before commons shipped, and
+commons shipped first. That order is deliberate rather than an oversight: a reason that beats this
+argument is a reason for the *guard's own port*, and commons would still track its declared
+source. Put to the guard as an open question 2026-08-11; unanswered at time of writing.
+
+**How it resolved, and why the resolution used the same rule rather than overturning it.** Both
+halves of that open question came back the same day. The guard answered that `[^><]` is a
+*measured* ReDoS fix on their side (their commit `cff0437`), not an aesthetic choice — so the
+"reason that beats this argument" the paragraph above asked for turned out to exist. And commons
+then measured its own copy and found the same defect in it: `<script\b[^>]*>` and
+`<iframe\b[^>]*src…` are both quadratic in scan length, the second one having been named by nobody
+until it was counted. `llm-security` re-measured rather than taking the report, reached `[^><]*`
+independently, and asked commons to carry it — because their table is now *built from this file*,
+so there is no local literal left for them to change without forking.
+
+The paragraph above said commons "would still track its declared source." That is exactly what
+`0.8.0` does: the declared source chose `[^><]*` and commons followed. The rule did not bend to
+accommodate a better argument — the argument won *at the source*, which is the only place this
+repository lets an argument decide a `pattern` value. The recall cost stated in the two bold rows
+of the table is now paid deliberately: measured across all 90 conformance cases, zero lost a match
+and zero gained one, so the dropped classes remain real and remain unwitnessed by the corpus.

+  chars of `'<iframe '`. **Both figures are superseded — see the correction box above:

+
+What this does and does not license:
+
+- It does **not** license changing either pattern here. Both are byte-identical to
+  `llm-security`'s source, and the behaviour-preservation invariant is not suspended because
+  the measurement is unwelcome. Commons carries `[^>]` on provenance and would carry `[^><]`
+  had the source been the guard's — that was true before this measurement and stays true after.
+- It does mean the finding is **owed to the owning runtime**, which is `llm-security` for both
+  patterns. Sent 2026-08-11, with these numbers and the `iframe-src` row they did not have.
+
+  **Outcome, same day:** the owning runtime reproduced both rows on its own vendored copy,
+  measured the exposure at its real entry-point caps (which the numbers above deliberately do not
+  cover — a pattern cost is not an exposure), judged it unacceptable, chose `[^><]*` over
+  `[^>]{0,256}` on the grounds that a bound is paddable, and asked commons to carry the change.
+  Commons `0.8.0` carries it. Note what did **and did not** license that: the measurement above
+  still licenses nothing on its own, and the two bullets stand as written. What licensed the
+  change is the *owner's decision*, arriving through the one channel this repository accepts for
+  moving a `pattern` value. Had they declined, the rows would still read `[^>]*` today and this
+  document would record a permanent divergence instead.
+- The guard's own honest disclosure belongs on the record too: their suite passes under both
+  forms (717 green), because the DoS row that ought to discriminate uses `'<script>'` as its
+  repeating unit, which supplies the `>` and never exercises the run. The invariant is
+  documented there and not test-enforced. A conformance case could hold it — but a fixture that
+  pins a *timing* property is a different kind of case from anything in this corpus today, and
+  minting one is not commons' call to take alone.

+# Secret-egress divergence — commons vs the Python guard
+
+**Status: informative.** Nothing here is normative and nothing here changes a data file. It
+records a measured disagreement between two tables that were believed to be two cuts of one
+source, and turns out not to be. Under this repository's behaviour-preservation invariant,
+a divergence found here is **reported, not fixed**.
+
+Produced 2026-08-13. Every number below came from a command; the scripts live in the session
+scratchpad rather than in this repository, because executable code here would breach the
+charter. They are reproducible from the method column. The guard was read via
+`git archive v0.7.0`, never from its working copy.
+
+**The premise this document was opened to test does not survive it.** The open question was
+recorded as "19 entries here against the guard's 25, cut at different granularity" — one
+table, two granularities. That is not what the two files are. They are ports of **two
+different source tables in the same source repository**, and the granularity difference is a
+consequence of that, not the cause. Everything below follows from correcting that premise.
+
+## What was compared
+
+| Side | Artefact | Version / coordinate |
+| --- | --- | --- |
+| commons | [`signatures/secret-egress.json`](../signatures/secret-egress.json) | file `version` 0.3.0, 19 entries |
+| guard | `llm-ingestion-pipeline-security` `src/llm_ingestion_guard/output.py` `_SECRET_PATTERNS` | tag `v0.7.0` = commit `be9759b`, 25 entries |
+| seed A | `llm-security` `hooks/scripts/pre-edit-secrets.mjs` `SECRET_PATTERNS` | commit `47905da`, 19 entries — what commons ported |
+| seed B | `llm-security` `knowledge/secrets-patterns.md` | commit `47905da`, blob `a7ed469`, 33 entries — what the guard ported |
+
+**The guard's v0.7.0 is the guard's current behaviour.** `git diff v0.7.0..aff3511 -- src/`
+is empty, where `aff3511` was the guard's head when this was measured. Pinning at the tag
+therefore costs no currency; it is not a waypoint measurement.
+
+**Seed B was read, not accepted.** The guard's module docstring asserts *"Ported from the
+`llm-security` `knowledge/secrets-patterns.md` seed"*. That assertion is a claim about a
+third repository and would be an attribution, not a finding, if it were relayed. It was
+measured instead: the file exists at the pinned commit on the public remote, and all 25 of
+the guard's ids appear in it verbatim — `0` guard ids are absent from seed B. The docstring
+is correct.
+
+**Both seeds are named in commons' own file.** `signatures/secret-egress.json`'s `$comment`
+already says which of the two it took and that the other *"is a separate PCRE-flavoured
+agent-consumed variant that stays where it is"*. What was not known until now is that the
+guard ported the other one.
+
+## Result
+
+| Measure | Method | Result |
+| --- | --- | --- |
+| Entry count, both sides | count entries | 19 and 25 |
+| Seed B entry count | parse the `.md` at the pinned blob | 33 |
+| Guard ids present in seed B | set membership on `id` | **25/25** |
+| Seed B ids the guard did not port | set difference | **8** |
+| Guard vs seed B, field-identical | compare regex (after stripping seed B's `(?i)` inline rendering), flags and severity | **16/25** |
+| — of the 9 remaining, escaping-only | unescape the guard's `\"` (a Python raw-string artefact) and compare for string identity | **4/4 identical** |
+| — of the 9 remaining, behaviourally real | differential match comparison | **5** — 4 connection strings, 1 capture-group change |
+| commons vs guard, byte-identical patterns | unescape both sides' `\/` and `\"`, compare source + flags | **2/19** |
+| Differential probe corpus | one witness per guard id, plus each side's exclusive shapes and the semantics witness | 36 probes |
+| Shapes commons reports and the guard is silent on | differential | **7 witnesses, across 5 commons entries** |
+| Shapes the guard reports and commons is silent on | differential | **3** |
+| Match-semantics divergence | one witness matching two entries on both sides | **1 label vs 2 labels** |
+
+16 field-identical + 4 escaping-only + 5 real = 25.
+
+**The `2/19` is the number that says these are not two cuts of one table.** Only
+`GitHub Fine-Grained PAT` ↔ `github-pat-fine-grained` and `OpenAI Legacy API Key` ↔
+`openai-api-key-legacy` are byte-identical after unescaping. Even `AWS Access Key ID` is not:
+commons has `AKIA[0-9A-Z]{16}` and the guard has the same run anchored, `\bAKIA[0-9A-Z]{16}\b`.
+The earlier note calling that pair the one clean 1:1 was wrong, and was wrong by transcription
+rather than by measurement.
+
+## Match semantics: the divergence that is not about membership
+
+This is the finding a membership table would hide, and it is the one a consumer implementing
+from commons will get wrong first.
+
+`signatures/secret-egress.json` declares ``match_semantics: "first match wins; patterns are
+evaluated in ascending `order`"``, marks `ordering.normative: true`, and names
+`last_entry_is_load_bearing: "JWT (three-part token)"` — the JWT entry is placed last
+precisely so a token inside an `Authorization` header is reported as the header, not as a
+bare JWT.
+
+The guard's `scan_secret_egress` runs `finditer` over all 25 patterns and adds a finding for
+every match. Order carries **no** semantics there, and there is no first-match-wins layer.
+
+Measured on one witness — an `Authorization` header whose value is a three-part JWT:
+
+| Side | Finding set |
+| --- | --- |
+| commons, under its own declared contract | `Authorization header with token` — one label |
+| guard, `scan_secret_egress` at `v0.7.0` | `egress:bearer-token`, `egress:jwt-token` — two labels |
+
+Both detect the credential. They disagree about what a report says, which is what a
+`conformance/expected.json` encodes. Two runtimes that both "pass" here would still produce
+different fixture files.
+
+The commons side of this was not hand-rewritten: the evaluator compiles the patterns out of
+the JSON, in `order`, applying `re.I` exactly where the file's own `dialect.translation_notes`
+say to, and stops at the first hit. The guard side is the imported module. Neither table was
+transcribed.
+
+## Membership, measured
+
+Every row below comes from running a witness input through both sides, not from reading the
+two regexes side by side.
+
+| commons `order` / name | guard ids observed | Relation |
+| --- | --- | --- |
+| 0 `AWS Access Key ID` | `aws-access-key-id` | 1:1, guard anchored |
+| 1 `AWS Secret Access Key` | — | **guard silent** |
+| 2 `Azure Connection String (AccountKey/SharedAccessKey/sig)` | `azure-storage-key` | overlap; see below |
+| 3 `Azure AD ClientSecret` | `azure-client-secret` | 1:1 |
+| 4 `Azure AI Services Key` | — | **guard silent** |
+| 5 `GitHub Token` | `github-pat-classic`, `github-oauth-token`, `github-server-token` | 1:3, **plus 2 prefixes neither guard id covers** |
+| 6 `npm Token` | `npm-token` | 1:1 |
+| 7 `Anthropic API Key` | `anthropic-api-key` | 1:1 |
+| 8 `OpenAI Project Key` | `openai-project-key` | 1:1 |
+| 9 `GitHub Fine-Grained PAT` | `github-pat-fine-grained` | 1:1, **byte-identical** |
+| 10 `Google API Key` | `gcp-api-key` | 1:1 |
+| 11 `Private Key PEM Block` | `rsa-private-key`, `ec-private-key`, `pkcs8-private-key` | 1:3, **minus one PEM label** |
+| 12 `JWT Secret` | — | **guard silent** |
+| 13 `Slack/Discord Webhook URL` | — | **guard silent** |
+| 14 `Generic credential assignment` | `generic-api-key`, `config-password`, `config-secret` | 1:3 |
+| 15 `Authorization header with token` | `bearer-token` (+ `jwt-token`, see semantics) | 1:1 |
+| 16 `Database connection string` | `postgres-connstr`, `mysql-connstr`, `redis-connstr` | 1:3, **minus the MongoDB SRV form** |
+| 17 `OpenAI Legacy API Key` | `openai-api-key-legacy` | 1:1, **byte-identical** |
+| 18 `JWT (three-part token)` | `jwt-token` | 1:1 |
+
+Guard ids with no commons entry firing on their own witness: `gcp-service-account-json`,
+`mongodb-connstr` — and `ec-private-key` on the `ENCRYPTED` header.
+
+`Azure Connection String` is listed as *overlap* rather than 1:1 deliberately. Commons'
+entry is `(?:AccountKey|SharedAccessKey|sig)=[A-Za-z0-9+/=]{20,}` — three alternatives, no
+length pin. The guard's `azure-storage-key` is `AccountKey=([A-Za-z0-9+/]{86}==)` — one
+alternative, exact length. The corpus witnessed only the `AccountKey` shape, where both fire.
+`SharedAccessKey=` and `sig=` were not witnessed; seed B carries them under separate ids
+(`azure-servicebus-connstr`, `azure-sas-token`) that the guard did not port. Read this row as
+"one witnessed overlap", not as a coverage claim.
+
+## What each side misses that the other catches
+
+**Commons reports, guard silent — 7 witnesses across 5 commons entries:**
+
+| Witness shape | commons entry | Why the guard is silent |
+| --- | --- | --- |
+| `ghu_` prefixed token | `GitHub Token` | guard ported `ghp`/`gho`/`ghs`; no id for `ghu` |
+| `ghr_` prefixed token | `GitHub Token` | same |
+| `aws_secret_access_key = <40 chars>` | `AWS Secret Access Key` | seed B has `aws-secret-access-key`; guard did not port it |
+| `Ocp-Apim-Subscription-Key` assignment | `Azure AI Services Key` | absent from seed B entirely |
+| `JWT_SECRET` assignment | `JWT Secret` | absent from seed B entirely |
+| Slack webhook URL | `Slack/Discord Webhook URL` | absent from seed B entirely |
+| Discord webhook URL | `Slack/Discord Webhook URL` | same |
+
+One row is one witness, so two commons entries appear twice: `GitHub Token` covers five
+prefixes behind one name, and `Slack/Discord Webhook URL` covers two hosts. Counting rows
+rather than entries would overstate how much of commons the guard is missing, and counting
+entries rather than rows would hide that `GitHub Token` is only *partly* uncovered — its
+`ghp`/`gho`/`ghs` prefixes map onto three guard ids just fine.
+
+Three of the seven are the sharper finding: the `Ocp-Apim-Subscription-Key`, `JWT_SECRET` and
+webhook shapes are not entries the guard declined to port, they are entries **seed B does not
+have**. Seed A carries three shapes seed B never did.
+
+**Guard reports, commons silent — 3 shapes:**
+
+| Shape | guard id | Why commons is silent |
+| --- | --- | --- |
+| `"type": "service_account"` | `gcp-service-account-json` | seed A has no GCP service-account marker |
+| `-{5}BEGIN ENCRYPTED PRIVATE KEY-{5}` | `ec-private-key` | commons' PEM alternation is `(?:RSA \| EC \| DSA \| OPENSSH )?`; `ENCRYPTED` is not in it |
+| `mongodb+srv://user:pw@host` | `mongodb-connstr` | commons' scheme run is `(?:postgres\|mysql\|mongodb\|redis)://` — the `+srv` suffix breaks the literal |
+
+The `mongodb+srv` miss is worth naming precisely: commons is not missing MongoDB, it is
+missing the **SRV** form, which is the form Atlas hands out. Plain `mongodb://` is caught.
+
+**This asymmetry is not a scoreboard.** Each side is faithful to its own seed. Every shape in
+the left table is present in seed A and absent from seed B; every shape in the right table is
+the reverse. Neither port is wrong about its source. The seeds disagree.
+
+## False-positive suppression: a layer commons has no field for
+
+The guard applies value-based suppression to the five entries that capture a value
+(`_is_fp_value`): structural placeholders (`your-`, `<`, `>`, `***`), word-boundary
+placeholder words (`example`, `changeme`, `todo`, …), variable references (`${`, `$(`,
+`os.environ`, `process.env`, …), all-same-character values, and values under 8 characters.
+
+Measured:
+
+| Witness | commons (first match) | guard |
+| --- | --- | --- |
+| `password: 'your-password-here'` | `Generic credential assignment` | — suppressed |
+| `api_key: '${MY_API_KEY_VALUE}'` | `Generic credential assignment` | — suppressed |
+
+Commons has no field that could carry this. `dialect.translation_notes` warns in prose that
+the generic entries are *"shape matches, not proofs of a live credential"* and assigns the
+trade-off to the consumer's policy — which is a correct statement of ownership and is also
+why two consumers reading commons will produce different reports on the same placeholder.
+Seed B carries the suppression semantics per entry in a `false_positive_notes` field; seed A
+carries name and pattern only, so commons had nothing to extract. This is a gap in the seed,
+not an omission in the extraction.
+
+## The connection-string bound
+
+The guard bounds the password run in all four connection-string patterns at
+`MAX_CONNSTR_VALUE = 256`, and its module explains why in full: an unbounded run in front of
+a required literal makes every start position rescan the tail when the literal never arrives.
+They measured 8.2 s at 100 000 characters on crafted `redis://:` input and extrapolated to
+hours at their own 1 000 000-character cap. Seed B's connection-string patterns are unbounded;
+this is one of the 5 real guard-vs-seed-B drifts, and it is a deliberate, documented one.
+
+Commons' `Database connection string` is `(?:postgres|mysql|mongodb|redis):\/\/[^\s]+@[^\s]+`
+— **shape-analogous** to what the guard bounded. Measured against the exact boundary:
+
+| Password length | commons | guard |
+| --- | --- | --- |
+| 12 | matches | `egress:postgres-connstr` |
+| 256 | matches | `egress:postgres-connstr` |
+| 257 | matches | — |
+| 300 | matches | — |
+
+Read this as two facts, not one verdict. Commons has recall the guard traded away above 256
+characters. Commons also carries the runtime shape the guard's measurement was about — and
+carries it in an *unanchored* form (`[^\s]+@[^\s]+` rather than the guard's
+`[^:@\s]+:…@[^\s'"]+`), so the two are not the same pattern under load and no timing claim
+about commons is made here. **Nothing is changed on that basis.** The entry is faithful to
+seed A, the file that owns it is `llm-security`'s, and the behaviour-preservation invariant
+puts the decision there. It is reported, and the guard's measurement is cited so the owner
+does not have to redo it.
+
+## Severity and ids: what commons does not carry
+
+Seed B carries `id` and `severity` per entry; the guard preserved both, and all 25 severities
+are field-identical to the seed. Seed A carries neither, so commons carries neither, and its
+`evidence_limits` says so explicitly: *"No severity, and no per-entry disposition, was
+supplied … so neither is invented here."*
+
+That restraint was right and it has a consequence: **commons has no id space for this table.**
+Its entries are keyed by human-readable `name` (`"GitHub Token"`), while the guard emits
+`egress:<id>` labels. A `conformance/expected.json` scoped to secret egress cannot be written
+against commons today, because a fixture names labels and commons has none to name.
+
+The 25 guard ids are **not guard-internal labels**. They are seed B's ids, adopted verbatim,
+which was measured above (25/25 present in the seed). That makes the id space question a
+question for `llm-security` first — they own both seeds and the id space in one of them — and
+for the guard second. Per this repository's naming rule, **no id is proposed here.** The rule
+that `carrier:*` established applies exactly: naming an id in a shared space is the exception,
+it requires both runtimes asked first, and publishing `aliases.<runtime>` is irreversible at
+file granularity.
+
+## What this does not show
+
+- **It does not show that either table is wrong.** Both are faithful ports. The disagreement
+  is between seed A and seed B, inside `llm-security`, and only that repository can say
+  whether two tables is intentional (one engine-consumed, one agent-consumed) or whether one
+  supersedes the other.
+- **It does not measure seed A's current state.** Commons' fidelity to seed A was verified at
+  commit `47905da` and this document adds nothing to that.
+  *(Seed B was read at the same commit, which is a shared coordinate and not the commit the
+  guard ported from. That was going to be a caveat — a seed-B entry that moved between the
+  guard's port and `47905da` would show up here as guard drift. It is dissolved by measurement
+  instead: `git log -- knowledge/secrets-patterns.md` in a deepened mirror returns exactly one
+  commit at or before `47905da`, `f153f96`, dated 2026-04-08, and the guard's `output.py` was
+  first committed 2026-07-04. The seed had been still for three months when the port was
+  written and has not moved since. Reading it at `47905da` reads what the guard ported from,
+  so the 5 real drifts are guard-side by measurement rather than by inference.)*
+- **It does not compare coverage.** The probe corpus has one witness per guard id plus each
+  side's exclusive shapes — 36 inputs. It is built to expose membership and semantics, not to
+  estimate recall. `SharedAccessKey=` and `sig=` Azure shapes, and seed B's 8 unported ids,
+  have no witness here.
+- **It does not measure the runtimes' entry points.** Both sides were driven at table level:
+  commons through an evaluator compiled from its own JSON under its own declared contract, the
+  guard through `scan_secret_egress` directly. What `scan_output` composes around it —
+  decode-and-rescan re-labelling findings as `decoded:egress:*`, the oversize cap — is not in
+  scope and would change the finding sets.
+- **It does not touch `manifest.json`.** `scope_planned.blockers` still names this divergence
+  as the blocker for egress cases. Whether this document dissolves that blocker or merely
+  describes it is a separate decision, and it depends on answers this document does not have.
+
+## Consequence for `conformance/`
+
+An egress case is not mintable today, and the reason has changed. It was recorded as "the two
+tables are cut at different granularity". The measured reasons are three, and they are
+independent:
+
+1. **No id space on the commons side.** A fixture names labels. Commons has names, not ids.
+   This is the hard blocker and it is the subject of the outgoing question to both runtimes.
+2. **Match semantics disagree.** Even with an id space, the Bearer-plus-JWT witness produces a
+   one-label expectation under commons' declared contract and a two-label one from the guard.
+   A fixture would have to encode one of them.
+3. **Membership disagrees in both directions**, and the disagreement is inherited from two
+   different seeds rather than from a porting error — so it cannot be closed by re-measuring
+   either port.
+
+None of the three is dissolved by a measurement this repository can run alone. Per
+`conformance/manifest.json` → `entry_points_by_scope`, a new scope also needs an entry point,
+a findings accessor and a fixture presentation for every runtime before its first case, and
+those three slots are empty for egress on both runtimes. That requirement stands independently
+of everything above.

 negative, which is the failure mode this corpus exists to catch. A case that cannot be run
 MUST be reported as an error, not as a pass.
 
+### 1.1 Declared tables and `not-applicable`
+
+The runtimes that share this core do not implement the same set of data files, and some
+never will: a table can be meaningful in an output gate and meaningless in the surface next
+to it. §1 as stated would make every such case a permanent failure, which reports an
+architectural difference as a defect and tells a reader nothing.
+
+A runtime claiming conformance therefore MUST declare **the set of commons data files it
+implements**, and MUST publish that set alongside its conformance result. A case whose
+`scope` (§4) names a data file outside the declared set MUST be reported as
+**`not-applicable`** — a third verdict beside pass and fail, and a different thing from the
+error of §1. §1's error means *this runtime tried and could not*; `not-applicable` means
+*this question was never addressed to this runtime*.
+
+A `not-applicable` case MUST still be enumerated in the result. It MUST NOT be counted as a
+pass, and MUST NOT be silently dropped from the denominator: `76/83 passed` and
+`76 passed, 7 not-applicable` describe different runtimes, and only the second one can be
+checked.
+
+Two constraints keep the verdict from becoming an exit:
+
+- A runtime MUST NOT withdraw a table from its declared set in order to convert failing
+  cases into `not-applicable` ones. The declaration describes what the runtime implements,
+  not what it would prefer to be asked. Narrowing it is a visible change to a published
+  claim, and it MUST be reported as such rather than made quietly between runs.
+- `not-applicable` attaches to a **table**, never to a case. A runtime that declares a table
+  MUST run every case scoped to it, including the ones it fails. Per-case opt-out is exactly
+  the silent skip §1 forbids.
+
+**The shape of the declaration.** A runtime publishing a declaration MUST use the shape in
+[`schema/conformance-declaration.schema.json`](../schema/conformance-declaration.schema.json):
+runtime, the commons commit measured, the declared table set, and the four verdict counts with
+their total. The requirement is the shape, not a validation step — nothing in this repository
+runs, so no runtime is gated on it. It exists because a free-form declaration makes
+`83 passed, 6 not-applicable` unparseable by anyone but its author, and a result only its
+author can read is not a cross-runtime measurement. That schema also carries the two arithmetic
+invariants this section implies but cannot state in prose without ambiguity: the counts MUST sum
+to the total, and the total MUST equal the corpus case count at the commit measured.
+
+A runtime SHOULD derive its declared set from the same constant its runner uses to accept or
+reject a `scope`, rather than maintain a second list beside it, and SHOULD record which of the
+two it did. The anti-narrowing constraint above is then structural rather than promised:
+narrowing the declaration is narrowing what the runtime accepts, which is a change to code with
+tests behind it instead of an edit to a published file nobody re-reads.
+
+**What the verdict does not say.** `not-applicable` records that a runtime does not implement
+a named commons table. It is not a statement that the runtime is blind to the phenomenon
+behind it — a runtime may well detect the same construct through some other mechanism that
+this corpus does not constrain, and reading the verdict as a coverage gap would assert
+something nobody measured. See §8.

+**"Belongs to" means published in that file, never "shares its prefix."** A runtime MUST
+decide membership by looking the id up in the scoped data file, and MUST NOT infer it from

 The scoping is what makes the exactness safe. The two seeding runtimes do not implement the

 would fail for reasons that have nothing to do with the pattern under test. Scoping the

+Through version 0.1.1 this paragraph ended "…asks a question both can answer", which held

+true the moment a case was scoped to `signatures/active-content.json`, which only one of them
+has. Scope narrows *what* is compared; it does not guarantee that every runtime is a valid
+addressee of the comparison. That second question is answered by the declared table set in
+§1.1, and a case scoped outside a runtime's declared set is `not-applicable` there rather
+than failed.
 
 The exactness is what makes the corpus worth running. A corpus that only checks that the
 expected finding is *present* is passed by a runtime that flags everything.

+`--` does not occur there either: the ratified ids use single hyphens throughout, measured
+across every id space this repository publishes and every case id in the corpus. That
+measurement is what keeps the reverse transform **lexical**. A runtime recovers a
+`pattern_id` by splitting the string, and MUST NOT need a lookup against the published id
+list to find where the id ends and the variant begins — a reverse transform that has to ask
+which of two readings is real is a different rule from the one written above, and it fails
+on the first id space that is vendored without its lookup table.
+
+**A `pattern_id` may carry more than one case.** Through corpus version 0.2.0 this section
+said the opposite: that a case id derives from a pattern id alone, so a single-finding scope
+holds at most one case per pattern id, with nowhere in the name to put a second. Corpus
+version 0.3.0 extended the derivation with the optional suffix above, and the corpus has
+shipped a case under it since (`hybrid-xss__script-tag--src-no-close`, whose own `$comment`
+carries the rationale for that one). The superseded sentence is named here rather than edited
+away, because it was the stated ground on which a real payload was dropped —
+`omitted_payloads` in [`conformance/manifest.json`](../conformance/manifest.json) records
+that ground as withdrawn and a second, independent ground as still standing.
+
+The bar for minting a second case is neither that the two inputs differ, nor that their
+in-scope finding sets differ:
+
+> A variant case MAY be minted when the second input can fail, **within the case's scope**,
+> under a change to a scoped data file that the first input would pass. Where no edit to a
+> published table separates the two inputs, the second case cannot fail in any way the first
+> does not, and it MUST NOT be minted.
+
+Equal in-scope finding sets do not settle that question, and reading them as if they did is
+the error this paragraph replaces. The corpus's first variant case expects exactly the
+finding set its base case expects — one `pattern_id`, one scope, one `match` — and still

 their own test suites; a renamed case is a silently disappeared test.

+### 7.1 Where the second paragraph does not hold
+
+**Through corpus version 0.8.1 this section stated the rule above with no scope at all**, and
+the scope was load-bearing: the justification names *two* implementations. Where a case's
+scope is a table only one runtime implements, and that runtime authored the payload the case
+was extracted from, there is no second implementation whose disagreement the paragraph could
+adjudicate. Which cases those are is recorded in the corpus, not asserted per run — see
+`active_content_provenance.asymmetry` in
+[`conformance/manifest.json`](../conformance/manifest.json).
+
+For such a case, a disagreement by the **seed runtime itself** is a third thing, and it is
+neither of the two the paragraph offers:
+
+- The fixture is not proven wrong. It recorded that runtime's behaviour correctly at the
+  commit and version its own measurement block pins, and a later classification does not
+  reach back and falsify an earlier measurement.
+- The runtime does not necessarily have a bug. Where the seed runtime has stated that the
+  classification behind such a table is calibration it does not freeze, a release that
+  classifies the payload differently is a change it reserved, not a defect.
+
+So: the fixture MUST NOT be rewritten on the strength of the divergence alone; the divergence
+SHOULD be recorded against the version pinned; and re-pinning the case to a later version of
+the seed runtime is a separate decision, taken deliberately and released on its own. This is
+the disposition §5 already applies to a stale `observed_out_of_scope` entry, extended to the
+one place where it can reach a verdict — and a divergence recorded here is the signal that
+the re-pinning decision is due, not a reason to leave it open.
+
+Three things this does **not** do.
+
+- **It creates no fourth verdict.** The counts of §1.1 and
+  [`schema/conformance-declaration.schema.json`](../schema/conformance-declaration.schema.json)
+  are unchanged: a case whose expected findings are not produced still **fails**, and is still
+  named in `failed_cases`. What changes is what the failure licenses concluding, not what is
+  reported.
+- **It does not reach a third-party implementer** of the same table. Against them the fixture
+  is the contract, exactly as §7 states — which is what these cases were minted to provide,
+  and the only thing they can prove while one runtime is all there is.
+- **It is not a licence to self-declare.** The exemption is carried by the corpus's own
+  provenance record for the scope. A runtime MUST NOT claim it for a case by asserting that
+  its own divergence is calibration.
