f926071348 fix(llm-security): compileRules coerces a non-string pattern instead of dropping the rule
new RegExp(pattern, 'i') never throws when pattern is a truthy non-string
(e.g. an object) — it ToString-coerces it first. The truthy-only guard
(`!rule.pattern`) let such a rule through as a real, compiled RegExp,
bypassing the try/catch meant to drop malformed rules. Worse than a silent
drop: `new RegExp("[object Object]", "i")` is parsed as a character class
over o/b/j/e/c/t/space, so the "dropped" rule instead becomes a
near-universal false-positive matcher. Same path for the built-in
commons-backed ruleset and the operator's sig.custom_rules_path (both
route through compileRules).

Fix: require typeof rule.pattern === 'string' before compiling. Verified
the golden dump pins no rule that exists only because of this coercion —
it regenerates byte-identically after the fix.

eceb71bbb3 fix(llm-security): SIG self-flagged the vendored commons it detects from
Scanning this repository with the SIG scanner produced 7 findings, 4 of them
on our own detection data: scanners/commons/CHANGELOG.md and
scanners/commons/signatures/malware-signatures.json. The ruleset that describes
xmrig and webshells is, byte for byte, a document containing those strings, so
the engine matched it as malware. EXCLUDED_PATH_RE already carried
knowledge/, tests/, docs/ and node_modules/ for exactly this reason; the
vendored commons arrived in v8 Phase 5 (bbada84) without being added.

One alternation branch closes it. Tests first: two cases added to
describe('signature-scanner: path exclusions'), both verified red against the
real scan() entry point before the regex changed.

Stated plainly, because it is a real cost and not a technicality: the branch is
`scanners\/commons` behind the existing `(^|\/)` prefix, so it matches that
two-segment path ANYWHERE in a target's relative path, not only at its root. A
webshell planted at vendor/scanners/commons/shell.php in a hostile repository is
therefore invisible to SIG. The second new test asserts that blind spot
deliberately, so it can never be discovered by accident. It is accepted because
anchoring at ^scanners/commons/ would miss the same payload one directory
deeper while re-opening the self-flag whenever the plugin is scanned from a
parent directory. TRG, AST, entropy and supply-chain still read these files;
only SIG identity-matching is blinded.

scanners/lib/supply-chain-data.mjs is NOT excluded. Its finding is a true
positive against real blocklist data.

Measured before: 7 findings. After: 3 (2 on STATE.md, 1 on
supply-chain-data.mjs). signature-scanner.test.mjs 23/23; custom-rules + e2e
54/54; golden-baseline 8/8 with suite-counts.json untouched.

bbada84e9f refactor(llm-security): build the SIG ruleset from vendored commons (malware-signatures 0.1.0)
Fifth and last consumer swap of v8 Phase 5 step 4. The seven known-bad-identity
signatures stop living in knowledge/signatures.json and are built from the
vendored commons artifact signatures/malware-signatures.json instead.

Measured before the swap over all seven positions -- id, family, severity,
pattern, description, provenance, key order, and recompilation identity under
the engine's unconditional `i` flag: zero divergences over 56 checks, in order.
The commons copy was extracted from this repository's own file at b0de0ca and
had not drifted.

knowledge/signatures.json is REMOVED rather than left in place. Keeping it would
have left two files spelling one table with nothing gating the drift, and its
golden `file:` pin would have gone on passing while pinning bytes no scanner
reads -- a gate reporting success without running. The pin is replaced by a
walked-module anchor over SIGNATURE_RULES, which is strictly stronger: the pin
covered the bytes on disk, the walk covers what `new RegExp` made of them.
Golden diff was exactly that and nothing else: 7 ADDED, 1 REMOVED, 0 CHANGED
(102/7/5 -> 109/7/4), each added source verified equal to the recompiled commons
pattern.

compileRules() moves into the new lib module and is exported, so the built-in
ruleset and the operator's sig.custom_rules_path path keep one implementation
rather than two copies of the defaulting logic.

Coverage by construction, not by memory: the probe table in the scanner test is
asserted against the LOADED ruleset, so a rule commons adds cannot arrive
without an end-to-end probe. Mutation of the vendored JSON fires in three
directions -- under-match (xmrig alternative dropped) reddens two scanner tests
plus golden; over-match (webshell rule widened to a bare `shell`) reddens the
clean-fixture false-positive probe plus golden; reorder reddens the declared-
order test plus golden.

Loud failure is contract: an unresolvable commons writes one line to stderr
rather than silently disabling known-malware detection, and never throws.

Suite 2247 / 2241 pass / 6 skipped / 0 fail. suite-counts.json untouched.

c9652a6d3d refactor(llm-security): build the secret table from vendored commons (secret-egress 0.3.0)
The 19 fixed credential shapes in pre-edit-secrets.mjs were regex literals;
they now come from signatures/secret-egress.json in the vendored commons via
a new scanners/lib/secret-egress.mjs. Policy-injected custom patterns (entries
20+) are unchanged and still appended by the hook.

Measured before the swap, not assumed: all 19 positions compared for order,
name, regex source and flags, plus recompilation identity, against the literal
table sliced out of the module text. Zero divergences. Commons had reported
the same result; that was their measurement, so this one was run anyway.

STATE's expectation that the golden gate would go red on both table records
and file sha256 was wrong: pre-edit-secrets.mjs is in neither PINNED_FILES nor
WALKED_MODULES, so the table had no golden coverage at all and the swap moved
nothing. Rather than leave the vendored data with only behavioural coverage,
secret-egress.mjs joins WALKED_MODULES — walked, not pinned, since it inlines
no regex of its own. Golden diff was 19 ADDED, 0 CHANGED, 0 REMOVED, each
source byte-identical to the pre-swap literal; re-blessed. suite-counts.json
untouched.

Tests: coverage is derived from the loaded table, so an entry commons adds
cannot arrive without an end-to-end probe. All 19 now block through the real
hook and are asserted by label, which also pins the ordering contract (a
Bearer-wrapped JWT must report as the header). Mutating the vendored JSON
fires in both directions plus reorder: under-match (AKIA quantifier) reddens
3 hook tests + golden; over-match (Anthropic key truncated to its prefix)
reddens the false-positive probe + golden; moving the JWT entry ahead of the
Bearer entry reddens the ordering test.

Suite 2231 tests / 2223 pass / 6 skipped. The two parallel-run failures
(pre-compact size-cap, benchmark) pass alone — the known timing flakes.

30dba2a457 docs(llm-security): recover the Windows sandboxing guidance stranded at the split
catalog found commit 0b795b1 sitting on `feat/add-ms-ai-architect` in the
marketplace forge -- a monorepo-path docs commit
(`plugins/llm-security/README.md`) that was only partially carried across
the repo split. Their read was that the CVE reference and
`transfer.fsckObjects` were rewritten into main independently while the
Windows half was never brought over.

Verified here before acting: `AppContainer`, `Windows Sandbox` and
`AppArmor` each grep 0 in our README and 0 at the published v7.8.3 tag,
while `CVE-2024-32002` and `transfer.fsckObjects` are present. Partial
transfer confirmed, not a deliberate drop.

Recovers the three missing pieces:
  - the per-platform sandbox matrix, including the Ubuntu 24.04+ AppArmor
    caveat that explains why bwrap fails there
  - the Windows options table (Windows Sandbox / Docker Desktop / WSL2 /
    AppContainer) with isolation level and requirements
  - the note on why Node's --permission model does not apply: it restricts
    fs access within the Node process and does not sandbox child
    processes, and git is a separate OS process

The layer table already in main is kept as-is -- it postdates the stranded
commit and is more accurate than the version there. Only the one-line
Windows sentence is replaced.

All 8 external links verified live (HTTP 200) rather than copied forward
on trust.

909dd581af docs(llm-security): consolidate GOVERNANCE.md to the canonical copy (org-ops D11)
Removes this repo's GOVERNANCE.md and repoints its one reference to the
canonical file in repo-standard, both in the same commit so no
LINK-INTERNAL-MISSING window opens between the two.

Verified here rather than taken from the census message: the canonical
URL returns HTTP 200, md5 3df3603325d3d6937fd560c3f67b5a5d, 131 lines --
matching org-ops' measurement exactly -- and a diff against our copy
shows only the generalising "plugin"/"marketplace" -> "repository"/
"organisation" wording, same 131 lines, no content removed.

Our copy was byte-identical to the stated baseline
(md5 736fc9d6af84fbd83c9cc7f860d8c8b7). Grep confirms README.md:5 was
the only reference in this repo, matching the measured site list.
Nothing gates on the file for us: GOVERNANCE.md is in required_files for
the catalog class only, and this repo's class is plugin.

18bc1dc92e fix(llm-security): the ReDoS gate timed every pattern and reached 8 of 45
The v8.x-A whole-table gate times every exported pattern against a corpus
of 8 hand-written units and asserts its own coverage -- but the assertion
`covers every exported pattern` guards the pattern LIST, not the input
corpus. A pattern is only measured if some unit happens to carry its
leading literal; otherwise it fails on the first character and reports
green having measured nothing.

Measured on the pre-swap tables: 37 of the 45 prefix-bearing patterns
were never reached, including BOTH quadratic hybrid-xss rows this gate
was believed to cover. `<script ` and `<iframe ` appear in no unit, so
the two rows commons independently measured as quadratic ran their
literal-prefix check and stopped. Same defect class as all of v7.8.2:
reported success without running.

Hand-writing 37 more units does not fix it -- it re-arms the same trap at
the next pattern. Class 3 derives each attack unit from the pattern's OWN
literal prefix, so coverage is a function of the table rather than a list
someone must remember to extend. 64KB rather than the 512KB read cap for
the class-1 reason: a quadratic pattern met at 512KB stalls the run for
minutes instead of failing it.

Proven to fire, both directions, against the vendored file:
  - gate written first, pre-swap: RED, naming script-tag 1429ms and
    iframe-src 1161ms against a 150ms budget (exit 1)
  - post-swap: GREEN, 17.7ms for all 45 probes (exit 0)
  - vendored JSON mutated back to [^>]*: golden AND ReDoS gates both exit 1
  - vendored JSON corrupted: golden exit 1, conformance 3 fail
  - restored: all green

Clean-table margin at 64KB is ~700x: worst legitimate pattern 1.66ms.

Carried with the commons v0.4.3 subtree pull, which is what makes the
gate passable. v0.4.0 was the tag commons announced; v0.4.1-v0.4.3 came
after and touch no data table -- lexicon 0.8.0 and secret-egress
0.3.0/19 are identical across all four -- so v0.4.3 was taken for the
conformance manifest correction (302625e) they sent separately.

Golden re-blessed after a post-by-post diff: exactly 2 changed records,
both [^>]* -> [^><]*, 0 added, 0 removed, reference run 61/61 unchanged.
The file-sha256 layer did NOT move, contrary to the note in STATE: it
pins scanners/lib/injection-patterns.mjs, which has held no literals
since be14867. The vendored lexicon is covered by the regex layer only.

The script-tag tripwire pinned the old form and fired correctly. Updated
to the v0.4.x form and widened to the iframe row, which had no tripwire
while it was quadratic -- which is why nobody had named it.

Full suite 2193 pass / 6 skipped. The one red is the documented
pre-compact size-cap timing flake; passes alone (exit 0), as do
attack-simulator and the gate itself.

47905dacae feat(llm-security): publish the spec 1.1 conformance declaration as an artifact
Closes the gap STATE has been carrying since e1511f9. Section 1.1's runtime
behaviour has been correct since then -- the third verdict is real, the
declared set is one constant with two uses -- but what we PUBLISHED was a
console.log summary: the right facts in a format only its author could
parse, which is most of what section 1.1 exists to prevent. Commons
shipped a shape for it in v0.3.0
(schema/conformance-declaration.schema.json 0.1.0), so the artifact can
now exist.

Every field is counted from the run rather than restated. The cases record
their own verdict as they execute, keeping `failed` (ran and disagreed)
apart from `error` (could not run) on exactly the distinction section 1
turns on. `commons_commit` is read out of the subtree-pull subject in our
own history rather than transcribed into a constant that would drift at
the next pull, and it refuses to publish a coordinate it cannot determine
-- a fabricated commit is worse than no declaration. The artifact is
gitignored: a committed declaration keeps asserting what was true once,
and nothing makes it wrong out loud when it stops being.

Validated once against the vendored schema with a real 2020-12
implementation: VALID, and the validator proven discriminating by six
negative controls it rejected (dropped zero-count, unknown key,
out-of-enum source, non-integer count, missing enumeration, malformed
case id). Continuous validation would mean a Python dependency in a suite
that has none, so what stays is the cheap half that actually drifts -- the
two key sets, asserted exactly.

TWO DEFECTS FOUND BY MUTATING THIS GATE, both in its own first draft:

1. It lived in `after()`. Measured on Node 25.8.2: an assertion that fails
   in an after hook prints under "failing tests" and marks the suite red,
   but leaves `fail 0` and exit code ZERO. `npm test` and CI would have
   read a falsified declaration as green. The gate against "reports
   success without running" was itself reporting success without running.
   It is now a test, declared last, and the verdict-count assertion is
   what guards the ordering that makes "last" meaningful.

2. Nothing tied the PUBLISHED `declared_tables` to the runner's constant.
   Substituting a literal list left every other assertion green, because
   they all read the constant rather than what was published -- so
   `declaration_source: derived-from-runner` could be a lie with no code
   change to point at. Now asserted identical.

Seven mutations, all exiting non-zero: dropped zero-count, falsified
not_applicable, unpublished field, hand-maintained tables, lied-about
source, and a hardcoded `passed` combined with a genuine case failure.

Published this run: 90 total, 84 passed, 0 failed, 6 not-applicable,
0 error, at commons 4641a7b (v0.3.0). Full suite 2192 pass / 0 fail /
6 skipped.

be148671ee feat(llm-security): swap injection tables to vendored commons lexicon
Third consumer swap of v8 Phase 5 step 4, after codepoints and OWASP_MAP,
and the last one with a behavioural gate behind it. The 83 regex literals
leave injection-patterns.mjs; the four arrays are now built in
scanners/lib/injection-lexicon.mjs from the vendored
lexicon/injection-lexicon.json and re-exported unchanged, so every
consumer sees the same published surface.

Behaviour-preserving by measurement, not by intent. The proven recipe ran
in order: a differential over all 83 positions (regex source, flags,
label, aliases.llm_security) found 0 divergences BEFORE anything changed;
the golden dump was then diffed post-for-post rather than read as a 9000-
character assertion, and the ONLY changed record was the sha256 of
injection-patterns.mjs itself -- 83 regex posts, 7 table records and all
counts identical. That single file digest is the diff a swap MUST produce,
so the baseline was re-blessed rather than silenced.

Two deliberate departures from the two earlier swaps:

FAILURE IS LOUD. codepoints and owasp-map fail silently on purpose: an
empty codepoint table weakens normalization, an empty OWASP map mislabels
a report. An empty injection table is different in kind -- scanForInjection
returns found:false for every input, and the UserPromptSubmit scan, the
MCP output scan and the pre-compact scan all go blind while reporting
success. That is precisely the v7.8.2 defect class, which bit this plugin
four times in one release. An unresolvable commons therefore writes one
line to stderr naming the disabled capability. It still does not throw:
hooks run per-tool-call, and a module-load throw breaks the tool call
instead of degrading the scan. The warning is suppressed for an explicit
commonsRoot, so tests and dev checkouts stay quiet and the line keeps
meaning something.

ENTRIES COMPILE DEFENSIVELY. commons is vendored data, not code. An
uncompilable pattern or unknown flag would throw inside new RegExp at
module load -- in a hook. Malformed entries are dropped instead, the same
call owasp-map.mjs makes for a non-array value.

Gates proven by mutating the vendored JSON in BOTH directions, five ways,
all firing: re-adding the script-tag tail commons dropped (golden 1,
lexicon 2, corpus 1), dropping a critical pattern (2/1/3), stripping the
`m` flag off a spoofed-header anchor (2/1), adding a pattern commons never
published (2/2/85), and removing commons outright -- which produced the
stderr line, four empty tables and 5 red rather than a green suite over
zero patterns. Lexicon restored byte-identical after each.

Full suite 2191 pass / 0 fail / 6 skipped (2184 -> 2197).

21a52ac49d chore(llm-security): pull commons subtree to v0.3.0, corpus 89 -> 90 cases
The subtree pull carries exactly one detection-data change: commons
converged `hybrid-xss:script-tag` on our open-tag-only form
(`<script\b[^>]*>`), dropping the `[\s\S]*?<\/script>` tail that was a
recall hole. Measured before the pull, not taken on their word: a
throwaway differential compared all 83 positions of the v0.3.0 lexicon
against the live source tables on source, flags, label and alias --
0 divergences, in order. The four vendored files were then re-hashed
against `git show v0.3.0:<file>` upstream; all four byte-identical.

Everything else in v0.2.0..v0.3.0 is additive: the CHANGELOG, the
divergence doc, spec text, the new §1.1 declaration schema, and one new
conformance case.

That new case is why the corpus tripwire moves. `manifest.count` is now
90 and `count_by_scope['lexicon/injection-lexicon.json']` is 84, because
`hybrid-xss__script-tag--src-no-close` gives the script pattern a SECOND
case. The tripwire fired on its own (actual 90, expected 89) rather than
being adjusted pre-emptively, so it is proven live this session.

`aliasMap.size` deliberately stays 83: the case-to-pattern relation is
now many-to-one, and only the alias map is a bijection. The header
comment says so explicitly, so the next reader does not "fix" the 83
into an 84.

Corpus: 84/84 passed, 6 not-applicable. Golden gate untouched (8/8) --
no table is built from the lexicon yet, which is the next commit.

088e45836c fix(llm-security): close OpenAI legacy key recall gap in pre-edit-secrets hook
Bare/unquoted legacy OpenAI keys (no label assignment, no Bearer prefix)
slipped past the pre-write secret-detection hook. Added a pattern anchored
on the T3BlbkFJ base64 "OpenAI" watermark (vendor-documented shape),
avoiding the collision-prone bare sk-+48alnum form. Failing tests first,
full suite green (2184/0/6).

The originally planned source for this fix — porting two entries from
commons' secret-egress.json — turned out to be a false premise: that file
is a byte-identical copy of this hook's own table, not a superset. The two
missing names existed only as prose in commons' conformance/manifest.json,
describing a different repo's (the guard's) unpublished Python table.
gcp-service-account-json was measured NOT to be a gap (already covered by
the existing PEM-block pattern); openai-api-key-legacy was the one real
gap, closed here with a locally-authored pattern rather than an invented
"port". Commons notified via coord-send that their secret-egress.json
(count: 18) is now stale.

e1511f91aa feat(llm-security): v8 Phase 5 - implement conformance spec 1.1 (not-applicable)
Commons v0.2.0 (532d70d) grew a MUST: a runtime claiming conformance must
declare the set of commons data files it implements and publish that set with
its result. The corpus went 83 -> 89; the six new cases are scoped to
signatures/active-content.json, which this runtime does not implement. Under
1 they would be six permanent failures; under 1.1 they are not-applicable, a
third verdict distinct from 1's error.

Published shape: 83/83 passed, 6 not-applicable. The six are enumerated by
name, reported as skipped rather than passed, and stay in the denominator.

The declaration is DERIVED from the same constant the runner uses to accept a
scope (DECLARED_TABLES), so it cannot drift from what the suite actually runs
- this is what was promised to commons in reply 20260811T104628Z.

Anti-narrowing was NOT enforced by construction, contrary to the claim in the
reply. Measured: setting DECLARED_TABLES to the empty set turns all 89 cases
not-applicable and leaves the suite GREEN with zero cases run - exactly the
exit 1.1 forbids. "Visible as a code change" describes a reviewer, not a gate.

Closed with a derived floor rather than a second hand-maintained table list
(which would be the parallel declaration we promised not to keep): a commons
table whose aliases name llm_security has registered this runtime as a
consumer per 3.1, and a registered consumer that stops declaring the table is
withdrawing a published claim. The universe of tables comes from the manifest;
membership comes from each table's own aliases. Measured: only the injection
lexicon names us, so the floor is one table and the other three carry no
obligation.

Mutation-proven, all six firing:
  declaration -> []                  green, 0 cases -> 1 fail   (the defect above)
  declaration -> wrong table         7 fail
  over-declare an unimplemented one  6 fail
  count_by_scope 83 -> 82            1 fail
  drop a case from manifest.cases    2 fail
  strip our alias registration       85 fail

Suite 2173 -> 2181 (+2 gates, +6 not-applicable), 2174 pass, 0 real failures.
The one red under parallel load was pre-compact-scan size-cap, a known timing
flake: 358 ms alone against a 1000 ms cap, 1886 ms under load. Budget untouched.

359066a3f7 refactor(llm-security): v8 Phase 5 step 4 - swap OWASP_MAP to commons
Second consumer swap of step 4. OWASP_MAP stops being a hardcoded constant in
severity.mjs and is built from the vendored commons artifact
mapping/owasp-map.json by a new scanners/lib/owasp-map.mjs, re-exported from
severity.mjs so the published surface (which the golden gate walks as
severity:OWASP_MAP) is unchanged.

Scope is one of the four maps commons publishes, and the omission is measured,
not incidental. OWASP_MAP has a production consumer: owaspCategorize() reads it
as the per-scanner fallback, and that reaches real report output through
output.mjs's owasp_breakdown. OWASP_AGENTIC_MAP, OWASP_SKILLS_MAP and
OWASP_MCP_MAP have none - every reference tree-wide is a test or a golden
artifact - so they stay source literals, the same call already made for
cyrillic_confusables in the first swap. Porting them would move data no runtime
reads into the load path.

Measured byte-likeness before the swap, all four taxonomies: same 16 prefixes,
same insertion order, same code arrays. Loadable verbatim, unlike the injection
table.

Content preservation proven the same way as the codepoint swap: the golden dump
differs in exactly one record, the sha256 of severity.mjs, which changes by
construction when a table leaves the file. All 83 regex records and all 7 table
records including severity:OWASP_MAP are byte-identical; reference-run.json
unchanged at 61/61. patterns.json re-blessed for the file digest only.

New property, not just preservation: the golden gate now pins the vendored
commons data transitively for this table too. Mutation-proven in both
directions - changing one code value and deleting a whole prefix each turn
three independent gates red (golden table digest, the new owasp-map gate by
name, and the pre-existing severity behaviour tests).

Entries are validated rather than trusted: commons is vendored data, and a
value that is not an array of strings would be spread straight into
owaspCategorize's category list, so a malformed entry is dropped. Graceful-empty
on an unresolvable commons, matching commons-loader's contract - severity.mjs is
on the import path of output.mjs and every orchestrated scanner, so a load throw
would abort a scan rather than degrade it.

Suite 2164 -> 2173, all green.

b1ba1fbdc6 refactor(llm-security): v8 Phase 5 step 4 - swap codepoint tables to commons
First consumer swap of step 4. ZERO_WIDTH_CHARS (5), the Unicode Tag range,
BIDI_CHARS (9) and HOMOGLYPH_MAP (28) stop being hardcoded constants in
unicode-scanner.mjs and string-utils.mjs and are built from the vendored
commons artifact codepoints/carriers.json by the new lib/codepoints.mjs.

Started here rather than at injection-patterns, which the plan ordered first:
that table is the one table that cannot be loaded verbatim (the
hybrid-xss:script-tag divergence is directional, and loading the lexicon as-is
would reverse the 90f576f recall fix). The codepoint tables were measured
byte-equal to the source constants BEFORE the swap - same members, same
values, same insertion order on HOMOGLYPH_MAP - so they load verbatim.

Proof the swap is content-preserving: the golden dump differs in exactly one
record, the sha256 of string-utils.mjs, which changes by construction when a
table leaves the file. All 83 regex records and the
table:string-utils:HOMOGLYPH_MAP digest are byte-identical, and
reference-run.json is unchanged at 61/61. patterns.json is re-blessed for the
file digest alone.

The gate is proven red-capable against the SUBJECT, both directions:
- dropping U+00AD from the vendored zero_width table fails the new
  codepoints gate by name, twice;
- altering one homoglyph value reddens the golden table digest AND a
  behavioural homoglyph test.
That second direction is a property the swap creates rather than preserves:
the golden gate now transitively pins the vendored commons data, where before
it pinned a source literal and a commons mutation was invisible to it.

NOT ported: commons carries cyrillic_confusables (13), and unicode-scanner.mjs
declares a set by that name - but nothing reads it. The homoglyph-mixing
detector tests isCyrillic(cp), the whole U+0400-U+04FF block. Loading it would
move dead data into the load path, so the dead const stays where it is and is
recorded instead. The recorded v8.x-B i/x drift between that set and the
lexicon class is therefore latent, not live. commons' private_use table has no
constant behind it here at all.

Graceful-empty is kept deliberately: codepoints.mjs is on string-utils'
import path and hooks import string-utils in fresh per-tool-call processes, so
a module-load throw would break the tool call rather than degrade the scan.
The loud half is the test, which asserts exact per-table counts through the
real default commons root - the same shape as the lexicon load-assertion.

Drive-by, unavoidable: the deleted JSDoc carried the "~25 entries" claim for a
28-entry table (v8.x-C). It needed a re-bless of the same file digest this
swap already forces, so it closes here at no extra cost.

Suite 2158 -> 2164, all green.

c67bad3752 test(llm-security): v8 Phase 5 step 3 - run the 83-case commons corpus
Vendored commons v0.1.0 carries a cross-runtime conformance corpus. Until now
it was measured by a throwaway script, which makes 83/83 a claim rather than a
gate - and step 4 swaps the very tables it constrains, so the measurement has
to survive into that step or it protects nothing.

Comparison is exact-within-scope per spec section 4: every listed finding must
be raised and no other lexicon finding may be. Findings are named by commons
pattern_id, which scanForInjection() does not carry - it returns our labels.
Section 3.1 permits a runtime registered in the lexicon's aliases object to
compare through it, and we are registered. Measured first, not assumed: the
map is a total bijection, 83 labels to 83 ids, no duplicates, family membership
agreeing throughout. Nothing here restates a pattern's id, severity or label,
so nothing here can drift from the lexicon.

Deliberately NOT done: adding an id field to our 83 table entries. It would
change the source file the golden gate pins by sha256, forcing a re-bless in
the middle of a behaviour-preservation measurement, and duplicate what step 4
does anyway when the table itself starts loading from commons JSON.

Case discovery is driven by manifest.cases and cross-checked against the
directories on disk, because section 1 requires every case to run and a
deleted case dir would otherwise shrink the gate silently. An unimplemented
match or scope throws rather than skips (section 4). Input bytes and sha256 are
both verified before scanning - two fixtures carry characters invisible on
screen.

Proven red-capable in both directions by mutating the subject, not the harness:
neutering one pattern failed exactly override__disregard; widening one to
[aeiou] failed 82 cases on extra findings. Source restored byte-identical after
each.

Suite 2158, 85 new. The one red in the parallel run is the known
pre-compact-scan size-cap flake (366 ms alone, 1060 ms under load).
2026-08-10 21:00:59 +02:00
44e5e39f67 test(llm-security): v8 Phase 5 step 3 - invert the unvendored-commons test
Vendoring commons v0.1.0 under scanners/commons/ falsified the premise of
`degrades gracefully when commons has not been vendored yet`: it asserted the
default DEFAULT_COMMONS_ROOT did not exist. It was the only red test after the
subtree add (2072/2073).

The graceful-empty contract it guarded is covered twice over by the
missing-artifact and invalid-JSON cases, which drive the same code path through
an explicit commonsRoot. So the replacement asserts the direction that is now
uncovered and matters more: a non-zero record count through the real default
root, no override.

That is the positive load-assertion Phase 5 step 4 requires. Every other gate we
have treats a commons load failure as indistinguishable from a legitimately
empty table, so a total loss of the vendored corpus would leave the suite green.
Proven red-capable by moving scanners/commons aside: the assertion fires by
name, not as an incidental TypeError elsewhere.

Suite 2073/2073.

90f576f056 fix(llm-security): v8.x-A - close <script> recall hole, add whole-table ReDoS gate
Two of the three confirmed v8.x-A evasions are closed; the third (attribute
padding) stays open by operator decision and is documented, not silently left.

Recall fix. hybrid-xss required a closing </script>, so `<script>alert(1)` and
`<script src=x.js>` both passed scanForInjection() with found: false, while the
closed form returned high. A src= tag has no body to close in the first place.
The opening tag alone is the signal, and matching it is strictly linear: one
negated-class run whose excluded character is its own terminator, so there is
no backtracking surface that could re-introduce v7.8.3 #24.

ReDoS gate. The #24 test covered six html-obfuscation patterns against the two
shapes that defect was found on. A catastrophically backtracking regex added
anywhere else in the four tables would have failed no test at all - which is
why #24 had to be found by hand. The new gate times every exported pattern and
asserts its own coverage, so it cannot be narrowed silently.

It has two classes because the blowup shapes need opposite inputs, and because
a synchronous RegExp.test() cannot be interrupted: an exponential pattern met
with a 512KB input would HANG the run rather than fail it. Class 1 uses a
28-char ambiguous-run ladder, where exponential costs ~1s and anything sane
costs microseconds; on a hit the 512KB sweeps refuse to run. Class 2 uses the
hook's real read cap to catch the polynomial #24 class. Proven to fire: an
injected exponential regex was named by label and the hang guard held.

Measured clean: worst single pattern 17ms, full large sweep 218ms.

Golden gate went red as expected and was re-blessed - diff is exactly two
lines, the regex source and the source-file digest. The 61-payload reference
run is byte-identical, so no showcase behaviour moved.

Suite 2073/2073 (was 2063; +5 recall tests, +5 gate tests).

Still open, unchanged: all 7 bounded HTML patterns evade on >256 chars of
padding, in two positions - before the attribute and inside the style value.
Wider than STATE recorded, which named only aria-label.

b0de0ca6d8 fix(llm-security): commons-loader - drop policy-driven root, ship path, fix cache [skip-docs]
Advisor review on the prior commit (69cad7c) caught a real detection-kill
vulnerability before push: reading `commons.root` from the SCANNED
TARGET's .llm-security/policy.json let a hostile cloned repo redirect
llm-security's own detection corpus to an attacker-supplied (empty)
one, with graceful-empty fallback making the substitution silent — a
substitutive override, unlike sig.custom_rules_path's additive one.
Dropped the policy import entirely; commons location is this plugin's
own concern, resolved only from __dirname or an explicit test/dev
override, never from policy or the scan target.

Also fixed two issues the review surfaced:
- Default vendor path was repo-root `shared/`, which package.json's
  `files` allowlist (bin/, scanners/, knowledge/) would never publish —
  moved under scanners/commons/, inside the directory that actually
  ships. Same defect class as 2fe2915 (green dev checkout, empty
  detection tables once installed).
- Cache keyed success/failure together, so the first caller's
  `fallback` shape (e.g. []) leaked to a second caller expecting a
  different shape ({}) on the same missing artifact. Cache now stores
  a load-failed sentinel and returns each caller's own fallback.
  Loaded artifacts are also deep-frozen, since the cache hands out one
  shared object by reference to every caller.

New/changed tests cover all four: a simulated hostile-target policy
file is ignored, the failure-cache no longer cross-contaminates
fallback shapes, and mutating a loaded artifact throws.

Golden baseline unchanged; full suite 2063/2063.

69cad7c973 feat(llm-security): v8 Phase 5 step 2 - commons-loader.mjs [skip-docs]
Thin, sync-read JSON artifact loader for the future vendored
llm-security-commons subtree, modeled on signature-scanner.mjs's
loadRules()/loadCustomRules() pair: process-cached, graceful-empty
fallback on any read/parse error, and policy-extensible via a
`commons.root` policy value (mirrors sig.custom_rules_path).

Unit-tested now against a local fixture — Phase 4 (commons repo
creation, gated on the operator creating the Forgejo remote) hasn't
run yet, so the default `shared/` vendor path doesn't exist in this
checkout. That "not vendored yet" case is itself asserted: the loader
must degrade to the caller's fallback, not crash.

Not wired to any consumer yet (that's Phase 5 step 4, table-by-table
behind the golden gate). No CLI/hook/scanner-visible behaviour exists
to document. Golden baseline unchanged; full suite 2063/2063 (2053 +
10 new).

2fe29152b3 fix(llm-security): golden gate - coverage block measured something else
The `coverage` block never looked at the 61 hook invocations. It probed every
payload STRING against every injection regex in-process, so `47/83` meant
"if you threw all 61 strings at all 83 patterns, 47 would match" - not "the
reference run exercised 47". The pre-bash-destructive payloads never reach
injection-patterns at all, yet their strings were in the probe set and could
mark a pattern exercised.

That number was asserted as reference-run coverage in three places that
instruct a future session: tests/golden/README.md, the STATE golden-gate
section, and the generator's summary line. In a repo whose v7.8.2 lesson was
"the check reported success without running", a figure that measures one
thing while labelled another is the same defect wearing a different hat.

Relabelled rather than re-measured - the probe still honestly bounds the gate
(an unreachable pattern is one the corpus cannot protect under ANY
attribution), it just has to say what it is:

  coverage.kind = 'static-reachability', with the caveat in a `note` field.
  patternsExercised  -> patternsReachable
  uncoveredPatterns  -> unreachablePatterns
  tablesExercised    -> corpusContains  (a payload CONTAINS a homoglyph; it
                        does not say the run folded one)

The gate now pins both the `kind` and the note, so the honest label cannot be
dropped quietly by a later edit.

Also surfaced the gap the old wording hid: the four OWASP maps have NO
behavioural coverage - they are scanner-side and no hook in this corpus
reaches them. They are precisely the tables the dump was widened to cover, so
the table digest is their only protection. Stated in the README next to the
47/83 line, where a reader was previously left to infer the reference run
backed them.

Flakiness check for the new gate (61 sequential spawns, ~12s, the most
process-heavy file in the suite, added to a suite npm test runs concurrently):
three consecutive full runs, 2053/2053, 0 fail. The three known
timing-sensitive files did not destabilise.

8d990e06d3 test(llm-security): v8 Phase 5 step 1 - golden baseline before any table swap
Records the reference artifacts Phase 5 swaps will be measured against, and
the gate that reads them. No extraction yet: this is the "before" picture,
and it had to land first or every later comparison would be confounded.
Typed test/ rather than feat/ deliberately - the only production change is
one widened export; the rest is gate, artifacts and generator.

Written failing-first (7 red on missing artifacts), then generated.

Three layers, because the plan's "assert .source/.flags of every regex" is
necessary but not sufficient:

  1. regex records - .source/.flags off the COMPILED object. After a swap a
     pattern is new RegExp(jsonString, flags), so the plan's named hazard
     (JSON backslash-doubling on 83+18 regexes) is visible here and nowhere
     else. Source-text comparison cannot see it.
  2. table records - key/value digests. Most of what Phase 4 moves is not a
     regex at all: HOMOGLYPH_MAP (x3, AS-IS), the typosquat tokens and the
     four OWASP maps are char->char and string->string data. A regex-only
     dump is blind to a broken homoglyph swap, i.e. to the bulk of the
     payload. Operator decision: widen the dump.
  3. file records - sha256 of the five moving-set sources. This dissolves
     STATE's open question (how to enumerate every regex): it is complete by
     construction, covering inline regexes in function bodies that no export
     walk reaches, with no JS parser in a zero-dep repo. A lexical count
     would have pinned a lie - severity.mjs scores 4 "regexes" that way and
     exports none.

Both layers were proven to fire, not assumed to: mutating one HOMOGLYPH_MAP
entry reddens the table layer, and widening an inline regex inside
decodeHexEscapes (unreachable by any export walk) reddens the file layer.

HOMOGLYPH_MAP is now exported from string-utils.mjs. That export is a source
change the plan already flags as a surface hazard ("private tables become
loaded"), so it is pre-paid here rather than confounding the before/after.

Reference run: the 61 showcase payloads through the real hook entry points,
sequentially - array order is semantic and the plan forbids key-sorting, so
concurrency is removed rather than sorted away. 61/61 match expectation,
which also settles the plan's open assumption that payloads.json expectations
match current behaviour. Coverage is recorded, not assumed: 47/83 patterns,
with the other 36 listed by key so the gate never implies coverage it lacks.

Suite counts are per-file, each file run alone - a total is unattributable,
and the three known timing-sensitive files flake only under concurrency.
2045 pass / 0 fail across 91 files, matching the pre-existing count exactly.
The gate's own file is excluded (it reads the artifact the run produces) and
that exclusion is named in the artifact.

Suite: 2053/2053, 0 fail.

fdec4b36ad feat(llm-security)!: v8 Phase 3 complete - riskScoreV1, posture heuristic, docs
Closes Phase 3 (B11) of the v8.0.0 plan. Three parts, all with the failing
test written first.

riskScoreV1 removed. scanners/lib/severity.mjs drops riskScoreV1() and its
SEVERITY_WEIGHTS_V1 table - @deprecated since v7.0.0, kept for diff/comparison,
zero callers in code or tests (re-verified, not taken from the plan). The v1
weights are recorded in CHANGELOG so an old score stays re-derivable. riskScore
(v2) is untouched; a test pins that one critical still lands in the 70-95 tier
and that 50 lows score below it, which is exactly the case v1 collapsed to 100.

Posture category 12 no longer keys off an identifier name. The check was
/TRIFECTA_MODE/i over the session-guard source, which measured what a constant
was CALLED rather than whether enforcement was configurable. With the env-var
gone, that regex would have dropped every correctly-migrated project from PASS
to PARTIAL - the gate punishing the migration it exists to encourage. It now
matches getPolicyValue('trifecta', 'mode', ...) and still accepts a pre-v8
vendored guard reading the old env-var, because a third-party project carries
its own hook copy and is equally configurable either way; the evidence line
says which of the two was found. The PARTIAL finding recommended setting an
env-var that v8 ignores; it now names the policy key. The grade-a fixture hook
moves to the policy-era form.

Two never-implemented env-vars deleted from the docs. LLM_SECURITY_SCR_OFFLINE
(ci-cd-guide) and LLM_SECURITY_OFFLINE (supply-chain-attack example) were
documented as OSV.dev / npm-audit kill-switches. No code has ever read either -
verified by grep across scanners, hooks and scripts, which finds them only in
markdown. A promised kill-switch that does nothing is worse than a documented
absence: it is trusted precisely when the run is meant to be air-gapped. The
docs now say there is none and that egress must be blocked at the network
layer. The LLM_SECURITY_AUDIT_* wildcard is narrowed to the one real key.

Docs. Migration section in README + CHANGELOG with the env-var -> policy-key
table, the detection commands (env + shell rc + .envrc + workflows), and the
explicit warning that a removed variable is now INERT rather than an error -
which is the failure mode that loses a project its configuration silently. The
hardening-guide env table splits into surviving vars and a removed-vars
migration table; its "promote to block" runbook named two variables that no
longer exist. Also swept: CLAUDE.md hook table, scanner-reference, ci-cd-guide,
both lethal-trifecta example docs, mitigation-matrix, injection-research.

Test counts in README/CLAUDE.md synced 2034 -> 2045.

Suite 2045 tests, 0 fail (2039 + 4 posture-trifecta + 2 riskScoreV1). The two
known parallel-load flakes did not recur this run.

b6af9b46df feat(llm-security)!: v8 Phase 3 step 1 - remove the deprecated mode env-vars
BREAKING CHANGE: the four LLM_SECURITY_* configuration env-vars deprecated in
v7.3.0 are removed. .llm-security/policy.json is now the only source:

  LLM_SECURITY_INJECTION_MODE     -> injection.mode
  LLM_SECURITY_TRIFECTA_MODE      -> trifecta.mode
  LLM_SECURITY_ESCALATION_WINDOW  -> trifecta.escalation_window
  LLM_SECURITY_AUDIT_LOG          -> audit.log_path
  LLM_SECURITY_DEPRECATION_QUIET  -> dies with the mechanism it silenced

Setting a removed var is now inert - it does not warn, and it does not
configure. Env-vars with no policy equivalent (PRECOMPACT_MODE,
PRECOMPACT_MAX_BYTES, UPDATE_CHECK, MCP_CACHE_FILE, IDE_ROOTS) are unaffected.

getPolicyValueWithEnvWarn and its one-shot stderr warning are deleted from
policy-loader.mjs, along with the module-scoped warned-var Set. The four call
sites collapse to getPolicyValue. getPolicyValue's JSDoc claimed "environment
variables ALWAYS take precedence" - it never read env itself, so that line
described the shim, and it is corrected rather than deleted.

User-facing hook strings that advertised a removed var as the escape hatch now
name the policy key instead: the inject-scan block reason, its warn-mode note,
both escalation-window advisories, and the trifecta block message. A blocked
user following the old text would have set a var that does nothing.

Tests. tests/lib/v8-env-removal.test.mjs is the regression gate and was written
failing first (8 of 12 red before the change). It pins the NEGATIVE - setting a
removed var does not alter the outcome - because that is the half that rots
silently: a re-introduced process.env read would leave every migrated positive
test green, since those configure through policy.json and never set the var at
all. One assertion walks hooks/scripts and scanners for `process.env.<removed>`
so the re-introduction is caught structurally, not only behaviourally.

The 44 env-driven test occurrences (18 inject-scan, 13+4 session-guard, 9
audit-trail) migrate to a throwaway .llm-security/policy.json via a new
runHookWithPolicy helper in hook-helper.mjs; audit-trail runs in-process, so it
supplies the same policy through CLAUDE_PROJECT_ROOT. The D3 mechanism tests in
policy-loader.test.mjs are deleted with the mechanism.

Suite 2039 tests, 2037 pass (+12 gate, -7 D3 mechanism). The 2 failures are the
known parallel-load timing flakes (pre-compact-scan size-cap,
pre-install-supply-chain F-3); both green when run isolated.

Remaining in Phase 3: posture-scanner TRIFECTA_MODE heuristic, riskScoreV1
removal, ghost-var cleanup, docs + migration note.

7336250c60 docs(llm-security): D12 disclosure + last dead pre-split reference
Two org-level findings from the coord inbox, both verified against source
before acting.

README.md:7 - org-ops D12 (docs/decisions.md, 2026-08-01) requires the
plugin-class disclosure line to be self-contained with THREE elements:
generator, process, and the ownership basis (Anthropic Consumer Terms
Section 4). Our line carried the first two. The wording mirrors the one
existing clause in the org (playground-design-system/README.md:21) rather
than inventing a second phrasing. LICENSE verified as MIT before asserting
it. Still one line at the measured head-block position, no link - D12
explicitly rejects both the mechanical sed form (drops ownership) and the
two-paragraph Provenance section (breaks the one-line form).

V3-UPGRADE.md:343 - org-ops census 03 identified this as the org's last
dead `claude-code-llm-security` reference, invisible to the repo-standard
gate because URL_REF requires :// or @host: before open/ and a schemaless
host does not match. Renamed to the post-split name; the file is kept.
CHANGELOG.md:751 is running prose about history with no URL position and
stays as-is.

c4dfee5762 docs(llm-security): trim README badge row 8 -> 4 (repo-standard BADGE-COUNT)
repo-standard v0.2.0 flagged two README findings via coord. Verified both
against ground truth before acting:

- BADGE-COUNT (WARN, real): 8 badges confirmed by manual count. All eight
  numbers were accurate -- commands 20, agents 6, hooks 9, knowledge 23,
  scanners 22 (27 top-level .mjs minus the 5 non-scanner modules, per the
  counting rule in docs/scanner-reference.md). The finding is about clutter,
  not staleness. Operator chose to keep Version, Platform, Scanners, License
  and drop the four inventory badges (Commands/Agents/Hooks/Knowledge) --
  each of those repeats a table further down the same page and adds a sync
  obligation to every version bump.

- README-H1 (WARN, operator's call): no change. The H1 is the human-readable
  product title; llm-security is the package id in plugin.json and the
  catalog. Renaming the H1 to the slug would be a readability regression.

doc-consistency.test.mjs pinned two of the removed/kept badges. The scanners
assertion still holds; the knowledge_docs badge assertion is dropped and the
test narrowed to the README prose claims, which remain derived from
knowledge/ contents. Full suite 2034/2034.

9a51e832b9 docs(llm-security): repo-standard gate to 0 ERROR
Ran repo-standard v0.1.1 against this repo (class: plugin, trait: security).
6 ERROR, 4 WARN, 1 SKIP recorded before any edit; now 0 ERROR, 12 checks pass.

BROKEN
- INSTALL-NO-CLI: added `claude plugin install llm-security@ktg-plugin-marketplace`
  beside the existing `marketplace add` line. The settings.json `enabledPlugins`
  block stays — it is a legitimate second form, just not a CLI command.
- LINK-OUTSIDE-REPO (README:7, reported by catalog): the disclosure link pointed
  at `../../README.md#ai-generated-code-disclosure`, relative to the pre-split
  monorepo and anchored at a heading that never existed. Replaced with the inline
  text the polyrepo migration's step 5 was meant to write.

MISSING
- `## Non-goals`: added as its own heading over the existing out-of-scope table
  inside `## Project scope`. The `## Project scope` heading is kept because
  SECURITY.md and CONTRIBUTING.md reference it by name.
- `## Changelog`: promoted from the trailing "Full history in CHANGELOG.md" line.
- `## Known limitations` (required by the `security` trait): renamed from
  `## What this plugin does NOT cover` — same table, contract heading.

WEAKENING
- README-DESC: opening line now matches the forge description verbatim, so
  description == catalog == README holds. This replaced the tagline
  "Automated defense and advisory analysis for the agentic AI attack surface."
- HEADING-LEVEL: `### Install` promoted to `## Install`; `## Quick Start` split
  into `## Requirements` / `## Install` / `## First scan`.
- BADGE-STATIC-CLAIM: dropped the static `tests-2034` badge. No runner exists on
  this forge, so the badge asserted a run nothing performs. Replaced under
  `## Self-scan` with the command that runs the suite from a clean clone, and
  the plain statement that nothing runs it automatically.
- LINK-NON-REPO x2: `open/claude-code-llm-security` (pre-split name) in
  V3-ANNOUNCEMENT.md updated to `open/llm-security`. Same dead name found in
  sarif-formatter.mjs TOOL_URI, which ships into SARIF output consumed by other
  tools, so it is corrected too.

Left standing, deliberately:
- WARN README-H1 `# LLM Security Plugin for Claude Code` != `# llm-security`.
  The gate defers this to the operator, and the description thread it protects
  is now carried by the opening line instead.

Suite 2034/2034.

0f1be986d0 docs(llm-security): v8 Phase 2 — B10 docs consistency, counts pinned by test
Extends tests/lib/doc-consistency.test.mjs with 15 cases that derive every
inventory count from source instead of trusting prose. Each count has one
stated derivation; a doc surface that disagrees now fails the suite.

Counts corrected (all were wrong before the test existed):
- orchestrated scanners: docs said 10 (README, ci-cd-guide), CLAUDE.md said 12,
  the synthesizer agent said 9 — scan-orchestrator registers 14
- total scanners: README badge + 3 prose sites said 23; the counting rule in
  docs/scanner-reference.md (14 orchestrated + 8 standalone) yields 22
- knowledge files: README badge + prose said 22; knowledge/ holds 23
- output.mjs finding() prefix JSDoc listed 10 of the 17 prefixes actually
  passed to it (missing IDE, MCI, MEM, PST, SCR, TFA, WFL)
- norwegian-context.md said "8 hooks, 10 scanners" -> 9 and 14
- ci-cd-guide "what gets scanned" table listed 10 of 14 rows; adds workflow,
  trigger abuse, signature, AST taint

Two plan items changed after verifying against ground truth:
- CLAUDE.md's synthesizer "(12 scanners)" was not a deliberate subset; the
  agent file itself claimed 9. Both bumped to 14.
- compliance-mapping.md's "13 posture categories" is substantively correct —
  its matrix has exactly 13 data rows, and categories 14-16 are governance
  consumers of the file, not rows in it. The planned 13->16 bump would have
  made the document false. Wording clarified to "code-level" instead, and the
  test now pins row count against the stated claim.

Framework currency (both verified against primary reporting):
- EU AI Act: Digital Omnibus (EP 2026-06-16, Council 2026-06-29) deferred the
  high-risk obligations behind Art. 9/15 to 2027-12-02 (Annex III) and
  2028-08-02 (Annex I); transparency still applies from 2026-08-02
- OWASP Agentic AI Top 10 labelled as the 2026 edition

Also: CLAUDE.md Distribution section rewritten monorepo -> polyrepo (each
plugin is its own repo; the catalog pins url + ref per plugin), and
current-state test counts synced 2013 -> 2034. Release-note paragraphs keep
their historical numbers.

No scanner, hook, or command behaviour changes. Suite 2034/2034.

ff4d8e8a31 fix(llm-security): v8 Phase 1 — Berry lockfile, nested-v1 recursion, per-occurrence strip attribution
Three TDD-first fixes surviving the B8 roadmap bucket (v8.0.0-plan.local.md
Phase 1, items 1-3; item 4 JAR hardening scoped out at review):

- supply-chain-recheck.mjs parseYarnLock: ported the hook's per-entry parser
  (pre-install-supply-chain.mjs) so Berry's `version: x` format (unquoted) is
  recognized alongside Classic's `version "x"` — Berry lockfiles previously
  yielded zero deps, silently missing pinned compromised packages.
- supply-chain-recheck.mjs parsePackageLock: lockfileVersion-1 fallback now
  recurses nested `dependencies`, mirroring the hook's walk() — a transitive,
  non-hoisted compromised copy below the top level was previously invisible.
- content-extractor.mjs stripInjection: attribution moved from a global
  `Set<label>` to `Set<label::lineIndex>`. The old check silenced the
  unstripped flag for ANY occurrence of a label once ANY occurrence had been
  line-redacted, so a second, cross-line-only encoded occurrence of the same
  label survived into sanitized output without being flagged.

Full suite 2019/2019 (one known-flaky timing test confirmed green in isolation).

b929ddc2bb chore(llm-security): untrack STATE.md — public remote requires LOCAL-ONLY
org-ops flagged that STATE.md is tracked in this public repo (open/llm-security),
contradicting the current global convention (public remote => STATE.md gitignored).
The .gitignore comment claiming the opposite was stale. Stops tracking going
forward; existing history is left untouched (already public).

32199965f2 fix(llm-security): post-mcp-verify reads live PostToolUse tool_response field v7.8.3
The PostToolUse hook read input.tool_output, but live Claude Code delivers the tool result as tool_response — so the indirect-injection scan on MCP tool output silently never fired outside the test harness (which sent tool_output). The hook now reads tool_response with a tool_output fallback for older harnesses/fixtures. +3 tests covering string and object tool_response and the precedence. Found via a live-session check during the v7.8.3 sweep; not one of the 52 MEDIUM-tier findings. Suite 2016/0.

4cffa30725 chore(llm-security): v7.8.3 — docs consistency + version bump (#8,#44,#45,#46,#47)
Bumps plugin to 7.8.3 (package.json, plugin.json, README version badge) and syncs the documentation surfaces that had drifted: orchestrated scanner count 9/10/13 to 14 (#8; the WFL/workflow scanner was omitted from the reference list), posture categories 13 to 16 (#44), red-team scenarios 64 to 72 (#45), tests badge/prose 1822 to 2013 (#46). Corrects the pathguard hook-table matcher and header comment to Edit|Write (follows the #9 fix) and removes the two dangling ROADMAP.md references (#47; the roadmap is not a public file). Adds the v7.8.3 CHANGELOG entry, README Recent-versions row, and CLAUDE.md highlights. The '23 scanners' total is a separate module count and is left unchanged.

14070160ba test(llm-security): cover TRG/SIG/AST in e2e pipeline + SIG miner/hacktool/rot13 families (#58,#59)
#58 the e2e scan-pipeline suite omitted trg/sig/ast from EXPECTED_SCANNERS and no fixture carried trigger-abuse/known-signature/python-taint content, so the three v7.8.0 scanners' surfacing through the aggregate was never asserted; added a fixture (shadowing command name → TRG, webshell → SIG, tainted os.environ→requests.post → AST, python3-guarded) that asserts each appears in the envelope and the rolled-up counts/owasp_breakdown. #59 the SIG cryptominer (SIG-MINER-001/002) and hacktool (SIG-HACKTOOL-001) families and non-base64 decode variants had no test; added family-attribution tests and a rot13-decode assertion. Test-only, suite 2013/0.

66e8ce2740 fix(llm-security): misc scanner correctness — reflog FP, diff exact-pass, hex dedupe, SARIF version (#20,#22,#50,#54,#56)
#20 git-forensics' reflog force-push detector had a redundant bare 'reset' term subsuming 'reset:', so any commit subject containing 'reset' tripped it; removed. #22 diff-engine's per-current moved-fallback greedily consumed a baseline candidate a later byte-exact match needed (mislabeling unchanged as new/moved on duplicate fingerprints); a global exact pass now runs before the moved-fallback. #54 memory-poisoning double-reported a 64+ char hex token as both base64 and hex; the base64 check now skips pure-hex tokens.

#56 SARIF output hardcoded driver.version 6.0.0 because the orchestrator called toSARIF() without a version; it now passes the real plugin version from package.json. #50 the VS Code known-malicious blocklist was empty with no explanation (unlike the JetBrains file's 'empty by design' note); added a matching blocklist_note.

8a59d616fb fix(llm-security): hook coverage — pathguard on Edit, trifecta window, pipe-to-shell, provider keys (#9,#10,#12,#13,#11-doc)
#9 pathguard registered matcher Write only, so an Edit/MultiEdit to an existing protected file (settings.json, .env, .ssh, the hooks themselves) bypassed it entirely; matcher now Edit|Write (the script already reads only tool_input.file_path). #10 the primary trifecta detector's 20-entry window counted marker lines, so accumulated markers scrolled a real leg out (false negative); the window now counts tool-call entries. #13 pre-edit-secrets caught bare provider keys only inside a quoted label assignment; added anchored patterns for Anthropic sk-ant, OpenAI sk-proj, fine-grained github_pat_, Google AIza, and JWT eyJ (minimum-length guarded against prose false positives).

#12 the remote-pipe-to-shell block required a shell immediately after the first pipe, so xargs/sudo/tee/env interposition evaded it and the comment falsely claimed xargs was caught; broadened to reach a shell through intermediate segments while leaving shell-OR fallbacks unblocked. #11 (doc only): knowledge/owasp-skills-top10.md claimed pre-bash-destructive blocks persistence commands — it does not; corrected to mark persistence detection as unimplemented/future (the detector itself is deferred to v8).

#21 the bash normalizer decoded only \xHH, leaving ANSI-C octal/\u/\U forms literal so canonical rm/curl never surfaced; now decodes all three. #23 file-discovery keyed on extname so .env.local/.env.example (extname .local/.example) were silently skipped; now matches multi-part suffixes. #42 a legitimate leading UTF-8 BOM was flagged HIGH (and the tool's own auto-cleaner refused to strip it); pos-0 BOM now excepted. #52 collapseLetterSpacing used a literal space, letting multi-space/tab spacing evade; now [ \t]+. #55 redact(_,60,0) did slice(-0) and leaked the whole unredacted URL; showEnd===0 now means no tail.

#30 embedded base64 (const x = "<base64>") never satisfied the whole-string decode, so the SIG identity engine never saw it; added decodeEmbeddedBase64 as an OPT-IN param on normalizeForScan (default off — appending a decoded copy would double-count per-match findings, e.g. content-extractor's injection scan) and enabled it only in signature-scanner, which dedups variants. #36 signature-scanner ignored the documented sig.custom_rules_path policy option; now loads+merges custom rules through the same family filter. Suite 2004/0.

b224e18b42 fix(llm-security): YAML/workflow parser divergence — block scalars + bare if: (#32,#33,#43)
#33 the frontmatter parser collected a block-scalar body (description: |) but did not skip it, so an indented name:/allowed_tools: inside the body re-matched as a top-level key and overrode the real values TRG-shadow and permission checks depend on; the parser now consumes block-scalar bodies as opaque content. #32 block-scalar headers carrying indentation/chomping indicators (|2, >-, |-2) were not recognized, so their bodies never reached the run: injection sink; now matched via a proper indicator/chomping regex.

#43 the B4 actor auth-bypass detector inspected only braced ${{ }} expressions, missing the canonical bare 'if: github.actor == ...' form (Synacktiv Dependabot-spoof false negative); bare if: expressions now emit a synthetic event the detector reads. Suite 2004/0.

#24 the HTML-obfuscation injection patterns had overlapping unbounded runs plus a required closing quote, so a non-closing input backtracked O(N^2) (~28.7s at the 512KB cap); quantifiers bounded, pathological input now 4ms. #53 mcp-live-inspect buffered MCP-server stdout via readline with no cap, so a hostile stdio server could exhaust memory / throw an uncaught RangeError; replaced with manual line buffering capped at 4MB that rejects pending RPCs and destroys stdout. #31 vsix-fetch's same-host redirect follower had no depth cap (loop hang); added depth>=5 cap mirroring the sibling fetcher.

#25/#51 mcp-description-cache and skill-registry wrote JSON via bare writeFileSync (non-atomic: concurrent load-modify-save loses updates, a torn read silently yields an empty registry); both now write a temp file then renameSync. Suite 1931/0.

#38 toxic-flow matched trifecta-leg keywords with bare includes(), so substrings ('url' in 'curl', 'key' in 'monkey', 'auth' in 'author') fabricated CRITICAL trifectas on benign components; now word-boundary matched. #40 TRG-broad fired HIGH on a bare any/all/every anywhere ('fix any lint errors'); the universal-claim regex now requires genuine universal phrasing. #41 TRG-baiting substring-matched ('any file' in 'many files'); now boundary-anchored. #39 the broad-name list missed multi-char generic names (helper/assistant/auto/general/agent/tool); widened coherently so it does not reintroduce #40. #57 the '(recovered from obfuscation)' label compared raw against a lowercased normal form, firing on any uppercase char; now gated on an explicit decode-changed flag.

#26 (same file) getPolicyValue used 'key in sectionObj' with no type guard, so a scalar section override in policy.json (e.g. {"injection":"block"}) threw an uncaught TypeError; now guarded to fall back to the default. Suite 1931/0.
