Adopting `active:raw-html-link` was one id. Publishing it honestly was the whole of `active_tag_class` — one function, three branches, no way to state the split without the no-URL narrowing and the 0.6.0 external-target rule. On the old predicate a bare `</a>` is active by name, so a consumer implementing from the hybrid would emit the new label where the seed runtime emits nothing. The file is now two pins, stated as two: v0.3.4/0bf0729 everywhere except the raw-HTML classifier, v0.7.0/be9759b there. The drift between them was measured field by field against the imported module rather than assumed, after stripping inline-flag rendering and applying the file's own declared quote normalisation so a spelling difference could not masquerade as drift. Exactly one published field had moved, and not the one this release was about: `html.active_tags` carried the MUTATOR's 23-name set where the gate means the SCANNER's 22. Correct at the 0.3.4 pin, wrong from 0.6.0 on. Kept as `html.mutator_tags`. The sweep covered 93 cases, not the 6 obvious ones. The narrowing can silence an `active:` finding inside the `observed_out_of_scope` evidence of a LEXICON case, and that field is guarded by no test anywhere — stale entries there survive forever. One case moved: html-obfuscation__aria-label, whose `<a aria-label=…>` carries no URL attribute. Its fixture is deliberately not rewritten; the residue is true at the commit `measurement` pins, and rewriting one of 83 would leave two commits under a header naming one. Recorded, dated and pinned in the manifest. The strongest check is not the digest: the checker rebuilds the published classifier from the JSON alone, importing nothing from the runtime, and differential-tests it against `active_tag_class` over 42 probe tags. 0 disagreements. That is what licenses shipping a classifier as data. No `aliases.llm_security` published, on this file or on carriers.

That was an accurate description of the rule and it cost a real case: see `omitted_payloads`, where the guard's seventh active-content payload was dropped for exactly this reason. The rule is now extended rather than worked around. NOTE that the omitted payload has NOT been added back — extending the derivation makes it expressible, but it was omitted on a second ground as well (its in-scope finding set is identical to the case built from coverage.py:476), and that ground still stands unexamined against the new rule. Adding it is a separate decision, not a consequence of this one."

See that file's `pattern_id_space.single_runtime`. `codepoints/carriers.json` (added in 0.4.0) is a THIRD standing again, and the difference is worth stating rather than leaving to be inferred: BOTH runtimes implement its tables — llm-security builds its zero-width, tag-range and BIDI sets from this very file — but only one of them has published a label for the finding. So its three cases are measured against the guard and are `not-applicable` for llm-security TODAY, for a reason that will lapse: the alias slot in `carriers.json` is empty because that runtime's carrier findings carry no id yet, not because it does not implement the table.

A shared id space presupposes a table reconciliation that has not happened. Membership diverges both ways, and `Slack/Discord Webhook URL` (order 13) and `Azure AI Services Key` (order 4) are here and absent from the guard. CORRECTED IN 0.3.1: through 0.3.0 this text ended '(the guard has `gcp-service-account-json` and `openai-api-key-legacy`, which are absent here; ...)'. Two entries were named as one kind of fact, and they are two different kinds. Measured here on 2026-08-11 by running this file's own patterns, in `order`, over a service-account document, against the guard at commit `e671edb` — 18 patterns then, 19 since `secret-egress.json` 0.3.0. (1) `gcp-service-account-json` is NOT a coverage hole here. A complete service-account key file matches this table at order 11, `Private Key PEM Block`: that pattern's prefix group `(?:RSA |EC |DSA |OPENSSH )?` is optional, so the bare PKCS#8 header `-----BEGIN PRIVATE KEY-----` such a file carries is matched. What differs is the CUT POINT: the same document with its `private_key` field removed matches nothing here, while the guard's `\"type\"\\s*:\\s*\"service_account\"` still fires — the guard detects the document MARKER, this table detects the KEY MATERIAL. Both fire on a real key file; only the guard fires on a stripped one. That is exactly the cut-point divergence this blocker is about, and it is not a missing entry. (2) `openai-api-key-legacy` WAS a real hole here and is CLOSED IN 0.3.2. Through `secret-egress.json` 0.2.0 no pattern in this file matched a legacy `sk-…T3BlbkFJ…` key, measured the same way, and llm-security's 18 -> 19 report stood recorded as their unreproduced claim because the commit carrying it was not yet on their public remote. It is now: `refs/heads/main` reads `47905da`, `088e458` is an ancestor of it (checked with `git merge-base --is-ancestor`, not read off their log), and `secret-egress.json` 0.3.0 carries the entry re-extracted from the module text at that commit, with all 19 positions compared for name, source, flags and order. So the two tables now agree on this one shape. What has NOT changed is the reason this blocker exists: 19 against 25 at different cut points is still a table reconciliation nobody has performed, and one closed hole is not that reconciliation."

"retired_blocker_text": "No adoptable id space, and until 0.3.3 the shape of the problem was mis-recorded here. CORRECTED IN 0.3.3: through 0.3.2 this text opened 'The guard emits TWO stage-coupled labels for the same carrier depending on pipeline position — `sanitize:zero-width` (input) versus `output:zero-width-present` (output), and the same split for bidi and unicode-tag'. The split is NOT the same for unicode-tag, and it was not the same on the day that sentence was written: the artifact-side label for tags is `lexicon:unicode-tags-present`, emitted from `lexicon.py`, not an `output:`-prefixed one. Checked at guard commit `e671edb` — the commit this blocker's sibling was measured against — where `coverage.py` already asserted that label, and re-measured at `a59184b`. So the earlier text was wrong when written, not stale. `output.py` states the delegation in a comment: Unicode-tag / PUA stego 'is already surfaced by scan_lexicon (`lexicon:unicode-tags-present`), so it is not repeated'. The labels are therefore not stage-coupled at all. The guard's `Finding` carries a `detector` field alongside `label`, and the prefix is that field's value: `lexicon:unicode-tags-present` carries `detector=\"lexicon\"`, `output:zero-width-present` carries `detector=\"output\"`, `sanitize:*` is emitted by `sanitize.py`. THE PREFIX NAMES THE DETECTOR, not the pipeline stage — and for tags one detector serves both entry points, which is why there is no sixth `output:` label to find. Measured 2026-08-11 at `a59184b`. What remains open is smaller than 'invent a stage-neutral id', and none of it is a naming question. Six labels exist to adopt verbatim, the way the lexicon's 83 ids were adopted from this same runtime: `sanitize:zero-width` / `output:zero-width-present`, `sanitize:bidi-override` / `output:bidi-present`, `sanitize:unicode-tag` / `lexicon:unicode-tags-present`. Three objections stand against adopting them, all measured at llm-security `47905da`: (a) `sanitize:` asserts an ACTION — the carrier was stripped — and llm-security strips nothing. `scanners/unicode-scanner.mjs` exports a single entry point, `scan(targetPath, discovery)`, which reports presence with `scanner: 'UNI'` and a prose `title` and no id at all. Adopting verbatim would hand one runtime an id whose name asserts something it does not do. (b) Three of the six name a persist gate llm-security does not have. The corpus already has the verdict for that — `not-applicable`, spec section 1.1, which attaches to a declared TABLE — and it applies cleanly today, because that runtime's `DECLARED_TABLES` names the lexicon and nothing else (measured at 47905da). WHAT REMOVES IT IS COMMONS PUBLISHING THE ALIAS: their suite derives its registered set by walking each vendored file for any node carrying an `aliases.llm_security` key, then asserts every registered table appears in the declared set — the section 1.1 anti-narrowing floor. The granularity is the FILE, not the entry. So a single carrier id carrying that alias forces `codepoints/carriers.json` into their declared set, obliges them to run all six carrier cases, and converts the three artifact-side ones from not-applicable into failures. Section 1.1 forbids the per-case exit by name, calling it the silent skip section 1 forbids. The choice is therefore between minting only the input-side three, accepting three standing failures that describe an architectural difference rather than a defect, and publishing carrier ids with no llm_security alias at all — a guard-only id space, worth choosing out loud rather than arriving at by omission. (c) The entry point pinned for llm-security in `measurement.runtimes` (`scanForInjection`, the injection scanner) does not reach carriers at all; carrier findings there come from the path-based unicode scanner instead. A carrier case therefore needs a per-scope entry point per runtime, which this manifest expresses nowhere — it pins one entry point per runtime for the whole corpus. Note that both runtimes already consume this file's tables: llm-security builds its zero-width, tag-range and BIDI sets from `codepoints/carriers.json` via `scanners/lib/codepoints.mjs`. The divergence is in what the finding is CALLED and where it can be observed, never in which code points are carriers. STATUS: put to both runtimes as a decision request on 2026-08-11 over coord, carrying exactly the three objections above and asking each the question only it can answer - the guard whether `lexicon:` on the tag path is intentional and whether `sanitize:` names a detector or an action, llm-security whether it adopts commons ids for carriers at all and which of not-implemented-per-runtime or mint-only-the-input-side it wants. Unanswered as of this version. A correction followed the same day, on this repository's own error: the request asserted that the corpus had no third verdict for an unreachable case, when section 1.1's `not-applicable` is exactly that and the registration mechanism above is what would take it away. Nothing is minted until both have ruled, and a further reason not to pre-mint is that publishing a single alias is itself the irreversible act — it moves another runtime's declared set by force of its own test suite."

"status_basis": "Not run, and the reason is a NAME rather than a capability: this runtime implements the carrier tables — it builds its zero-width, tag-range and BIDI sets from this file — but its carrier findings carry no id yet (`scanner: 'UNI'`, a severity and a prose title, stated by it on 2026-08-13). Until it publishes a label and the alias is added here, the file is outside its declared set and these three cases are `not-applicable` under spec section 1.1.",
|
|
"measurement_boundary": "This repository does not execute consumer code and its carrier entry point is path-based besides, so no result for this runtime was produced by any means. `observed_out_of_scope` naming only the guard is therefore a measurement boundary, not an oversight — the same boundary `authored_payloads` records for the variant lexicon case."

"inputs_chosen_rather_than_taken": "Unlike the 83 lexicon cases and the 6 active-content ones, these three inputs come from no runtime's payload set — neither runtime ships carrier payloads. They were authored here and each was checked to produce exactly one in-scope finding and no residue, so that each case measures ONE carrier. Candidate inputs whose tag payload decoded to an injection string were probed and set aside for the same reason `prepare_input` was set aside as an entry point: a fixture that trips two detectors measures two things.",
|
|
"known_boundary_not_minted": "U+200D between two emoji is EXEMPT on both of the guard's surfaces since v0.6.1, and the guard warned that a naive zero-width fixture carrying an emoji-adjacent joiner would be failed by design. Verified here at `be9759b`, and the zero-width fixture carries a bare U+200B between two letters instead. The exemption itself is a real behavioural boundary and a candidate variant case; it is NOT minted, because three cases were ratified and because whether the exemption is a shared rule or one runtime's policy has not been put to the other runtime."
