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).

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

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).

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 
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.

#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.

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).

#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.

#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.

196517f38a fix(llm-security): supply-chain gate bypasses — npm/yarn blocklist + pip-audit (#14-#19,#48) 
#18 dep-auditor called 'pip audit' (no such subcommand) so Python CVE detection was a permanent silent no-op; now spawns 'pip-audit' with an argv array. #19 it audited the scanner HOST's env with results mislabelled to the target's requirements.txt; now audits the target via -r and skips cleanly when absent.

#14 the offline npm blocklist was skipped for bare/range/tag installs because it used the (null) parsed-spec version; now re-checks the resolved version before the OSV network path. #15 non-hoisted nested lockfile keys derived the wrong package name (leading-only node_modules/ strip); now strips to the last segment. #48 lockfileVersion-1 nested dependency trees are now walked recursively.

#16/#17 the yarn.lock matcher paired two unassociated whole-file substrings with an unanchored pkg@ (false BLOCK of a legit package) and only matched Yarn Classic quoted versions (Berry known-malware allowed); rewritten as a per-entry parser that associates version to its own entry, anchors the name, and matches both Classic and Berry.

76f190cf78 fix(llm-security): AST-taint clears taint on reassignment (#29) + sink test coverage (#28) 
py-ast-taint.py Assign handler never removed a name from the tainted set on reassignment, so a source-then-constant/sanitizer rebind (g=os.getenv(); g='safe'; os.system(g), or x=shlex.quote(x)) kept stale taint and fired false AST-CMD-EXEC findings. Assign now clears taint for target names when the RHS is not a source. No cross-expression propagation added — the f-string/concat/alias recall gap (#27) stays deferred to v8.

#28: added fixtures+assertions locking the tainted subprocess/os.system AST-CMD-EXEC sink and the open(...,'w') AST-FILE-WRITE sink. Suite 1931/0.

f4c65070ff chore(llm-security): v7.8.2 — security patch release 
Bumps package.json, .claude-plugin/plugin.json and the README badge to
7.8.2; adds the release entry to CHANGELOG.md, docs/version-history.md,
the README recent-versions table and the CLAUDE.md highlights block.

Also fixes test pollution introduced with the ide-extension regression
suite: its temp roots used an `llmsec-jb-plugin-` prefix, and
jetbrains-parser.test.mjs asserts globally that no `llmsec-jb-*`
directory survives anywhere in tmpdir. The shared prefix made that
assertion fail depending on test order — it passed on the first full run

566c281b56 chore(llm-security): remove leftover debug probe from tests/ 
probe-rm.mjs was self-labelled "Temporary probe — delete after
debugging". It is not a test (no node:test harness, no assertions — it
prints exit codes), it ran against a hardcoded absolute path into the
INSTALLED marketplace copy rather than this repo, and it exercised the
rm-block cases that are now covered properly by
tests/hooks/pre-bash-destructive.test.mjs.

a035455979 fix(llm-security): out-of-range char-ref silently emptied a plugin.xml field 
decodeEntities guarded parseInt with Number.isFinite, which bounds
nothing: any numeric character reference above 0x10FFFF produced a
finite integer that String.fromCodePoint rejects with RangeError.

Correction to the review's framing: this does NOT break parsePluginXml's
no-throw contract. The per-field safe() wrapper catches it. The actual
defect is quieter — the affected field is discarded and replaced with
'', with only a warning. A plugin whose <name> carries one out-of-range
reference parses as name: "" while pluginId and every other field
survive, so name-based checks (JetBrains typosquat detection against the
top-plugin list) run against an empty string.

Severity is below the HIGH it was filed as: a document containing a code
point above 0x10FFFF is not well-formed XML, so IntelliJ would reject
such a plugin too — the evasion yields a plugin that does not load. The
fix is still correct and one line of logic.

- isDecodableCodePoint(): integer, >= 0, <= 0x10FFFF.
- Undecodable references are now left literal, matching how lenient
  parsers treat unrecognised entities and how this same function already
  treats unknown named entities.

Regression test drives parsePluginXml with hex and decimal references
just past and far past the maximum, asserts the no-throw contract still
holds, and pins that valid references, the maximum valid code point, and
named entities still decode.

4f21374e8c fix(llm-security): HIGH — obfuscated injections were reported but not stripped 
stripInjection is the remote-scan indirection layer: its `sanitized`
output is what an LLM agent actually reads, verbatim, via
sanitized_content in the evidence package. It scanned two variants of
each file — the raw text and normalizeForScan(text) — but removed
matches with `sanitized.replace(match[0], ...)` against the RAW text
only.

For a match found in the decoded variant, match[0] IS the decoded
string, which by construction does not occur in the raw text. The
replace was therefore a silent no-op: the finding was reported while the
encoded payload was passed to the agent untouched. Every obfuscation the
normalizer exists to defeat — HTML entities, URL encoding, \u escapes,
hex, base64, letter-spacing, Unicode tags — reached the agent intact.
The worst case is the intended one: detection said "critical injection
found" and shipped the injection along with the verdict.

- Pass 1 redacts the whole source LINE whose own normalized form carries
  the pattern. Line granularity is deliberate: decoding is not
  length-preserving, so decoded match offsets cannot be mapped back onto
  the original text.
- Pass 2 keeps the existing literal replacement and finding collection.
- Residual gap, made explicit rather than silent: a payload encoded
  across MULTIPLE lines matches whole-text normalization but no single
  line, so it cannot be attributed. Those findings now carry
  `unstripped: true`. Whole-file redaction was considered and rejected —
  normalizeForScan base64-decodes any long blob, so a benign asset could
  blank an entire file's evidence.
- stripInjection exported via __testing, and main() is now behind the
  standard isMain guard (copied from dashboard-aggregator.mjs) so
  importing the module does not execute the CLI. CLI verified unchanged
  against the evil-project-health fixture: 7 files, 6 injection
  findings, risk_level critical.

This boundary had no direct test coverage before this commit.

npm test: 1890/1890 green (1884 + 6 new).

4e16ea0e72 fix(llm-security): HIGH — one unparseable JetBrains plugin crashed ide-scan 
The two manifest parsers disagree on how they signal failure:
parseVSCodeExtension returns a bare null, parseIntelliJPlugin returns a
TRUTHY { manifest: null, warnings }. scanOneExtension guarded only the
bare-null form, so every JetBrains failure path — lib/ missing, lib/ not
a directory, lib/ unreadable, no jars in lib/, no jar extractable — fell
through the guard and dereferenced `manifest.hasSignature`.

The resulting TypeError propagated out of scanOneExtension into
mapConcurrent, which awaited fn() with no per-item try/catch, so
Promise.all rejected and the ENTIRE ide-scan aborted. One malformed
plugin directory on disk was enough to take down the scan of every
other installed extension — including, in an audit context, a plugin
that is malformed precisely because it is hostile.

- scanOneExtension: guard is now `!parsed || !parsed.manifest`, and the
  parser's own warnings are carried into the result so the reason for
  the skip survives instead of being replaced by a generic message.
- unscannableExtension(): the result envelope is extracted so the early
  return and the isolation belt below produce the same shape.
- Belt (defense-in-depth): the scanOneExtension call site catches per
  extension and yields an unscannable result. mapConcurrent stays
  generic — the isolation lives at the call site, not in the helper.

Regression test drives scanOneExtension across all four JetBrains parse
failure paths plus a no-invented-findings assertion.

npm test: 1884/1884 green (1879 + 5 new).

f031dd496f fix(llm-security): HIGH — entropy suppression keyed off the absolute path 
Rule 4 in isFalsePositive ("test/fixture files intentionally contain
example secrets") matched /(test|spec|fixture|mock|__test__|__spec__)/i
against absPath — the ABSOLUTE path. Any directory name above the scan
root therefore silenced every entropy finding in the entire target: a
repo cloned to a CI workspace, checked out under a parent folder named
`testing`, or scanned from any path with one of those substrings
reported zero secrets and still exited status 'ok'. The failure is
silent — indistinguishable from a clean scan.

- isFalsePositive takes relPath and rule 4 keys off it. relPath was
  already computed and passed down to scanFileContent; only the
  suppression check was reading the wrong one.
- classifyFileContext keeps using absPath: it reads the basename
  extension only, so directory names above the root cannot affect it.
- Rules 1-3 and 5-13 are untouched.

Regression test drives scan() end-to-end against temp roots named
llmsec-test-*, llmsec-spec-*, llmsec-fixture-* and llmsec-mock-*, with a
neutral-root control proving the payload is detectable, plus two
guards that genuine suppression still works (a *.test.mjs file and a
file under a relative tests/ directory).

npm test: 1879/1879 green (1872 + 7 new).

a92b3c5962 fix(llm-security): HIGH — bare root/home targets bypassed the rm block 
The BLOCK rule named "Filesystem root destruction" did not block the bare
root target it is named for. The target alternation ended in a shared `\b`,
and a word boundary cannot hold after `/` or `~` at end-of-command.
Measured against the shipped pattern:

  bare `/` target        NOT blocked      `$HOME` target   blocked
  bare `~` target        NOT blocked      `/usr` target    blocked
  `/*` glob target       NOT blocked
  swapped flags (-fr)    NOT blocked
  sudo-prefixed          NOT blocked

Only targets whose first character is a word character ever satisfied the
assertion, so the rule caught `/etc` but not bare root. These fell through
to WARN (exit 0) — advisory only, command executed.

- Pattern: `\b` moved onto the `$HOME` alternative alone, where it is
  meaningful (it ends in a word char, so `$HOMEDIR` is still not
  swallowed). Dropped from `/` and `~`. Nothing else changes: `/etc`,
  `/home`, `./build` behave exactly as before.
- The old test file encoded this defect as expected behaviour, with a NOTE
  claiming the pattern "requires separate flag groups (e.g. -f -r, not -rf
  combined)". That diagnosis was wrong — the `/etc` case blocks fine with
  merged flags. Comment replaced with the real root cause.

npm test: 1872/1872 green (1865 + 7 new).

f083cdad2e fix(llm-security): CRITICAL — command injection in auto-cleaner (v7.8.1) 
validateContent() syntax-checked .mjs/.js/.cjs candidates via
execSync(`node --check "${tmpPath}"`), where tmpPath derives from the
untrusted scanned-repo FILENAME. The F-2 guard checks path containment
but never quotes or strips shell metacharacters, so a file named
`x";<cmd>;".mjs` in a scanned repo turned `/security clean` (live is the
documented default) into arbitrary command execution. Verified with a
live PoC before the fix.

- validateContent: spawnSync('node', ['--check', tmpPath]) — no shell.
- CLI orchestrator fallback: same treatment (argv array, explicit
  status/error handling instead of execSync's throw-on-nonzero).
- Belt (defense-in-depth): applyFixes now refuses findings whose `file`
  carries shell or control metacharacters, reported as skipped.
- Regression tests cover both layers separately, so the belt cannot mask
  a re-introduced shell in the sink.

Kjell Tore Guttormsen
6d3c4b5052 chore(llm-security): v7.8.0 — TRG/SIG/AST scanners 
Session C of the security-fix track: cut the TRG/SIG/AST release now that the
F-1/F-2/F-3 security gates pass. Pure version-sync — the three scanners shipped
in Steps 1-7 (616e7ff..fc7cf57); no production code changes here.

Version-sync 7.7.2 -> 7.8.0 across every current pointer: .claude-plugin/
plugin.json, package.json, README.md badge, and the CLAUDE.md header + "release
notes" range sentinel. Narrative additions (prior releases kept as history):
- CHANGELOG.md: new [7.8.0] entry (Added: TRG/SIG/AST; Changed: prefix
  registration + knowledge/ packaging).
- docs/version-history.md: new v7.8.0 section describing the three scanners.
- README.md "Recent versions": new 7.8.0 row.
- CLAUDE.md: new v7.8.0 highlights paragraph above the v7.7.2 one.

TRG/SIG/AST recap (built Steps 1-7, behind the security-fix gate):
- TRG (scanners/trigger-scanner.mjs) — trigger/activation-abuse: TRG-shadow /
  TRG-baiting / TRG-broad over name+description frontmatter, decode pipeline
  first (LLM06/AST04).
- SIG (scanners/signature-scanner.mjs) — pure-Node known-malware identity engine
  over raw bytes + decode pipeline; rules in knowledge/signatures.json
  (LLM03/LLM02).
- AST (scanners/ast-taint-scanner.mjs) — parse-only python3 taint helper
  (scanners/lib/py-ast-taint.py) with graceful regex fallback (LLM01/LLM02/AST02).

Release gate: full node --test suite 1863/0 after the doc edits. No scanner,
hook, or command behaviour changes.

dfb663fa61 fix(llm-security): F-2/F-3 — contain path traversal + kill npm-view shell injection 
Session B of the security-fix track. Both sinks trusted untrusted strings at a
filesystem/subprocess boundary; same fix family as F-1.

F-2 (HIGH, arbitrary file write) — scanners/auto-cleaner.mjs: applyFixes() did
resolve(targetPath, f.file) with no containment, then wrote the cleaned content
back. f.file is untrusted (scanned-repo filenames, or a fully attacker-chosen
--findings file), so file: "../../.claude/settings.json" let the cleaner modify
files OUTSIDE the scanned tree. Add a prefix-containment check before grouping:
absPath must equal targetPath or start with targetPath + sep, else the finding
is refused and reported as skipped. (Documented residual gap: prefix containment
does not stop a symlink inside the tree pointing out — noted inline.)

F-3 (HIGH, command injection, pre-confirmation) — hooks/scripts/
pre-install-supply-chain.mjs: inspectNpmPackage ran execSafe(`npm view ${spec}
--json`), a shell string. spec derives from package tokens parsed out of the
scanned Bash command, so a metachar-bearing token reached the shell on
PreToolUse(Bash) — BEFORE the install, so it ran even if the user then denied
the command. Switch to spawnSync('npm', ['view', spec, '--json']) (no shell);
spec is passed as one argv element. The static `npm audit --json` execSafe call
is left as-is (no interpolation).

TDD (repro -> red -> green):
- tests/scanners/auto-cleaner-traversal.test.mjs: a "../secret.txt" finding must
  not rewrite the outside file; contained files still get cleaned.
- tests/hooks/supply-chain-injection.test.mjs: `npm install $(>/abs/PWNED)`
  (redirect-only $(...) survives normalizeBashExpansion + the whitespace split)
  must not create the sentinel.

Closing gates: full node --test suite 1863/0 (was 1860; +3); gitleaks clean;
F-1 regression re-run GREEN (sink still closed).

e46b5a3256 fix(llm-security): F-1 — eliminate shell-injection RCE in git-forensics scanner 
git-forensics ran execSync(`git ${cmd}`), interpolating attacker-controlled
filenames from the SCANNED repo (git ls-files / git log --name-only) into a
shell string. A hostile repo containing a file named `commands/$(touch X).md`
achieved zero-interaction RCE on `/security scan <url>`: gitScan is in the
default scanner array and runs OUTSIDE the git-clone OS sandbox (which wraps
only the clone), so it executed unsandboxed on all platforms.

Convert the git() helper to spawnSync('git', [...args]) with no shell; every
call site now passes discrete tokens (shell quoting removed — git does its own
pathspec globbing). The helper throws on non-zero exit, preserving existing
per-category/per-file try/catch semantics.

TDD: adds a failing-first regression (tests/scanners/git-injection.test.mjs)
that builds a hostile-filename fixture repo and asserts the injected command
never runs. RED against execSync, GREEN after the fix.

Also removes two stray committed root artifacts (F-5/F-6): `--json`
(0-byte redirect husk) and .orphaned_at.

Closing gates: full node --test suite 1860/0; gitleaks clean. F-2/F-3 follow
in Session B.

92bd99f2a8 docs: security fix brief for next session — F-1 RCE + F-2/F-3 sinks 
Action brief from the marketplace-wide review (see docs/review-2026-06-20.md). Three shell/path
injection sinks: F-1 CRITICAL zero-interaction RCE in git-forensics.mjs (execSync shell string +
attacker-controlled filenames; reproduced), F-2 HIGH path-containment write in auto-cleaner.mjs,
F-3 HIGH command injection in the supply-chain hook. Common fix: execSync(string) -> spawnSync(array)
/ input containment. DO AFTER the current active session finishes.

Disclosure hold: this brief + review-2026-06-20.md (ff9bd13) are committed locally but NOT pushed;
push both only together with the F-1 fix (the brief carries a working RCE repro payload).

## [Unreleased]
### Removed — BREAKING
- **The four `LLM_SECURITY_*` configuration env-vars deprecated in v7.3.0.**
`.llm-security/policy.json` is now the only source. A removed variable is
**inert**: it neither warns nor configures, so a project relying on one
silently returns to the default. See the Migration section in `README.md`
for the detection commands.
| Removed env-var | Policy key | Default |
|-----------------|------------|---------|
| `LLM_SECURITY_INJECTION_MODE` | `injection.mode` | `block` |
| `LLM_SECURITY_TRIFECTA_MODE` | `trifecta.mode` | `warn` |
| `LLM_SECURITY_ESCALATION_WINDOW` | `trifecta.escalation_window` | `5` |
| `LLM_SECURITY_AUDIT_LOG` | `audit.log_path` | unset |
| `LLM_SECURITY_DEPRECATION_QUIET` | *(none)* | dies with the warning it silenced |
Env-vars with no policy equivalent are unaffected:
`LLM_SECURITY_PRECOMPACT_MODE`, `LLM_SECURITY_PRECOMPACT_MAX_BYTES`,
`LLM_SECURITY_UPDATE_CHECK`, `LLM_SECURITY_MCP_CACHE_FILE`,
`LLM_SECURITY_IDE_ROOTS`.
`getPolicyValueWithEnvWarn` and its one-shot stderr deprecation line are
deleted from `scanners/lib/policy-loader.mjs`; the four call sites collapse
to `getPolicyValue`. Hook strings that advertised a removed variable as the
escape hatch now name the policy key — a blocked user following the old text
would have set a variable that does nothing.
- **`riskScoreV1()`** in `scanners/lib/severity.mjs`, plus its
`SEVERITY_WEIGHTS_V1` table. `@deprecated` since v7.0.0, kept for
diff/comparison, with zero callers in code or tests. The v1 weights are
recorded here for anyone re-deriving an old score:
`critical 25, high 10, medium 4, low 1, info 0`, summed and capped at 100.
`riskScore()` (v2) is untouched, so no score, band, or verdict moves.
- **Two documented env-vars that were never implemented.**
`LLM_SECURITY_SCR_OFFLINE` (`docs/ci-cd-guide.md`) and `LLM_SECURITY_OFFLINE`
(`examples/supply-chain-attack/README.md`) were promised as OSV.dev / npm-audit
kill-switches; no code has ever read either. The docs now say plainly that
there is no kill-switch and that an air-gapped run must block egress at the
network layer. The `LLM_SECURITY_AUDIT_*` wildcard phrasing (README,
`docs/scanner-reference.md`, `docs/security-hardening-guide.md`) is narrowed
to the single real key.
### Changed
- **Posture category 12 (Rule of Two) no longer keys off the identifier
`TRIFECTA_MODE`.** The check was `/TRIFECTA_MODE/i` over the session-guard
source, which measured what a constant was *named* rather than whether
enforcement was configurable at all. It now matches
`getPolicyValue('trifecta', 'mode', …)`, and still accepts a pre-v8 vendored
guard reading `LLM_SECURITY_TRIFECTA_MODE` — third-party projects carry their
own hook copy and are equally configurable. Without this, every correctly
migrated project would have dropped from PASS to PARTIAL. The PARTIAL
finding now recommends the policy key instead of the removed env-var.
## [7.8.3] - 2026-07-18
Security and correctness patch. 47 verified fixes from the v7.8.1/v7.8.2
completion-review MEDIUM tier (52 findings triaged: 48 confirmed defects, with
3 feature-requests and 1 non-defect scoped out; capability work — the #11
persistence detector and #27 AST-taint f-string recall — deferred to v8). No
new features, and no CRITICAL/HIGH: every review-claimed HIGH downgraded to
MEDIUM on re-verification. 2013 tests, 0 fail.
### Fixed
- **Supply-chain gate bypasses.** The offline npm blocklist was skipped for
bare/range/tag installs (resolved version never re-checked); non-hoisted
nested lockfile keys derived the wrong package name; the yarn.lock matcher
both false-BLOCKed a legitimate package (unassociated substrings + unanchored
`pkg@`) and missed Yarn Berry's `version:` format; `pip audit` (no such
subcommand) made Python CVE detection a permanent silent no-op and, once
corrected to `pip-audit`, audited the target instead of the scanner host.
- **Hook coverage.** pathguard registered `Write` only, so an Edit to an
existing protected file (settings, `.env`, `.ssh`, the hooks themselves)
bypassed it — now `Edit|Write`. The trifecta window counted marker lines and
could scroll a real leg out. The remote-pipe-to-shell block missed
xargs/sudo/tee/env interposition. pre-edit-secrets missed bare provider keys
(Anthropic, OpenAI, fine-grained GitHub PAT, Google, JWT).
- **Scanner robustness / DoS.** Quadratic ReDoS in the HTML-obfuscation
injection patterns (~28s to 4ms); unbounded readline on MCP-server stdout
(memory exhaustion / uncaught RangeError); an uncapped same-host redirect loop
in the VSIX fetcher; a scalar `policy.json` section override threw an uncaught
TypeError; non-atomic writes to the MCP-description and skill-registry caches.
- **False positives / negatives.** toxic-flow fabricated CRITICAL trifectas from
substring keyword matches (`url` in `curl`); TRG-broad/-baiting fired on scoped
phrasing and substrings; a legitimate leading UTF-8 BOM was flagged HIGH; the
workflow actor-auth-bypass detector missed the bare `if:` form (Dependabot
spoof); the git reflog force-push detector tripped on any `reset` in a commit
subject; the diff engine mislabeled unchanged findings on duplicate
fingerprints; memory-poisoning double-reported a hex token as base64 + hex.
- **Parser divergence / evasion.** YAML block-scalar bodies were re-parsed as
top-level keys (name/allowed_tools override) and indented/chomped block-scalar
headers (`|2`, `>-`) were unrecognized; the bash normalizer decoded only
`\xHH`, not ANSI-C octal/`\u`/`\U`; embedded base64 (opt-in) now reaches the
SIG decode pipeline; `.env.local`/`.env.example` were silently skipped by
discovery; `collapseLetterSpacing` (multi-space/tab) and `redact(_, _, 0)`
(full-URL leak) were fixed; the SIG scanner now honours the documented
`custom_rules_path` policy option.
- **Docs / version consistency.** Orchestrated scanner count corrected to 14,
posture categories to 16, red-team scenarios to 72, tests badge to 2013; SARIF
`driver.version` now reflects the real plugin version; the pathguard matcher
and persistence-detection documentation were corrected; dangling `ROADMAP.md`
references removed.
- **MCP output-injection scan was inert in live sessions**
(`hooks/scripts/post-mcp-verify.mjs`). The hook read the PostToolUse
`tool_output` field, but live Claude Code delivers the tool result as
`tool_response`, so the indirect-injection scan on MCP output never ran
outside the test harness; it now reads `tool_response` and falls back to
`tool_output`. Found via a live-session check during the sweep, not part of
the MEDIUM-tier triage.
### Deferred (to v8)
- Persistence-command detection (cron/launchctl/rc-files/plist) and the
AST-taint f-string/concat/alias recall gap — capability enhancements, not
defects in shipped code.
- Deterministic detectors for AST09 (bulk knowledge load), AST10/LLM10
(unbounded consumption), and MCP05 (path-traversal read sink) — each already
covered by the LLM-agent layer.
## [7.8.2] - 2026-07-18
Security patch. Fixes five defects from the v7.8.1 completion review, four of
which caused a scanner or hook to fail silently — reporting success while the
check it was named for did not run. No feature changes. 1901 tests, 0 fail.
### Fixed
- **HIGH — bare root/home targets bypassed the rm block**
(`hooks/scripts/pre-bash-destructive.mjs`). The BLOCK rule's target
alternation ended in a shared `\b`, and a word boundary cannot hold after `/`
or `~` at end-of-command. `rm -rf /`, `rm -rf ~`, `rm -rf /*`, `rm -fr /` and
the sudo-prefixed forms all fell through to WARN (exit 0) — advisory only,
command executed. Only targets starting with a word character (`/etc`,
`/usr`) were ever blocked. `\b` now applies to the `$HOME` alternative alone,
where it is meaningful.
- **HIGH — entropy suppression keyed off the absolute path**
(`scanners/entropy-scanner.mjs`). The test/fixture suppression rule matched
`/(test|spec|fixture|mock|__test__|__spec__)/i` against the **absolute**
path, so any directory name above the scan root silenced every entropy
finding in the entire target while still reporting status `ok`. The rule now
keys off the path relative to the scan root.
- **HIGH — one unparseable JetBrains plugin crashed the whole ide-scan**
(`scanners/ide-extension-scanner.mjs`). The two manifest parsers disagree on
how they signal failure: `parseVSCodeExtension` returns bare `null`,
`parseIntelliJPlugin` returns a truthy `{ manifest: null, warnings }`. Only
the bare-null form was guarded, so every JetBrains failure path dereferenced
`manifest.hasSignature`; the TypeError escaped through `mapConcurrent`'s
unguarded `Promise.all` and aborted the scan of every other installed
extension. Guard widened, plus per-extension fault isolation at the call
site.
- **HIGH — obfuscated injections were reported but not stripped**
(`scanners/content-extractor.mjs`). `stripInjection` scanned both the raw and
the decoded text but removed matches only via a literal replace against the
raw text. For a decoded-only match, `match[0]` is the decoded string, which
by construction does not occur in the raw text — so the replace was a silent
no-op and the encoded payload reached the LLM agent verbatim via
`sanitized_content`, alongside a finding announcing it. Every obfuscation the
normalizer exists to defeat was affected. Decoded-only matches are now
removed by redacting the source line; multi-line payloads that cannot be
attributed are flagged `unstripped: true` rather than left silently.
- **Out-of-range numeric character reference emptied a plugin.xml field**
(`scanners/lib/ide-extension-parser.mjs`). `decodeEntities` guarded
`parseInt` with `Number.isFinite`, which bounds nothing, so any code point
above `0x10FFFF` made `String.fromCodePoint` raise `RangeError`. The
no-throw contract held (the per-field `safe()` wrapper catches it), but the
affected field was discarded and replaced with `''`. Undecodable references
are now left literal. Filed as HIGH; it is lower — such a document is not
well-formed XML, so the plugin would not load in IntelliJ either.
### Changed
- `stripInjection` (content-extractor) and `scanOneExtension` (ide-extension-
scanner) are exported for testing; `content-extractor.mjs` runs `main()`
behind the standard `isMain` guard so importing it no longer executes the
CLI. The remote-scan injection boundary had no direct test coverage before
this release.
### Removed
- `tests/hooks/probe-rm.mjs` — a self-labelled temporary debug probe with no
assertions, pointing at a hardcoded path into the installed marketplace copy.
## [7.8.1] - 2026-07-18
Security patch. Fixes a CRITICAL command-injection defect in the auto-cleaner
that shipped in v7.8.0. No feature changes. 1865 tests, 0 fail.
### Fixed
- **CRITICAL — command injection via scanned filename**
(`scanners/auto-cleaner.mjs`). `validateContent()` syntax-checked
`.mjs`/`.js`/`.cjs` candidates with
``execSync(`node --check "${tmpPath}"`)``, where `tmpPath` derives from the
**untrusted scanned-repo filename**. The F-2 guard added in v7.8.0 checks
path containment but neither strips nor quotes shell metacharacters, and a
filename containing `"` closes the interpolated quote. A repository shipping
a file named ``x";<command>;".mjs`` therefore turned `/security clean` —
whose live mode is the documented default — into arbitrary command execution
on the operator's machine. Verified with a live proof-of-concept before the
fix. Both subprocess call sites (the syntax check, and the CLI's
scan-orchestrator fallback) now use `spawnSync` with an argv array, so no
shell parses the path.
- **Defense-in-depth:** `applyFixes()` now refuses findings whose `file` field
carries shell or control metacharacters, reporting them as `skipped` rather
than passing them to any sink. This guards against a future call site
re-introducing string interpolation.
### Changed
- `validateContent` is exported from `scanners/auto-cleaner.mjs` so the
regression suite can exercise the subprocess sink directly, independently of
the `applyFixes` guard that would otherwise mask it.
## [7.8.0] - 2026-06-20
Three new deterministic deep-scan scanners (TRG/SIG/AST) targeting the
skills/agents attack surface. Each ships with its own finding
prefix, OWASP/AST mapping, policy block, fixtures, and graceful-skip
behaviour. Built behind a security-fix gate: the F-1/F-2/F-3 shell-injection
and path-traversal fixes landed first. No existing scanner, hook, or command
behaviour changes. 1863 tests, 0 fail.
### Added
- **TRG — trigger/activation-abuse scanner** (`scanners/trigger-scanner.mjs`).
Inspects command/agent/skill `name` + `description` frontmatter for three
activation-surface abuses: `TRG-shadow` (name collides with a built-in
command/tool and intercepts it), `TRG-baiting` (description uses
maximally-activating phrases — "anything", "always", "all files" — to bait
indiscriminate invocation), and `TRG-broad` (a generic name plus a
universal-applicability claim, so the unit auto-activates beyond its stated
purpose). Descriptions pass through the decode pipeline (zero-width strip →
homoglyph fold → `normalizeForScan`) first, so obfuscated baiting still
trips. Thresholds and the phrase/built-in lists are policy-overridable via
`.llm-security/policy.json` (`trg`). OWASP LLM06 (excessive agency); AST04.
- **SIG — known-bad-identity signature engine**
(`scanners/signature-scanner.mjs`). Detects known-malware *identity* —
webshells, reverse shells, cryptominers, hacktools — complementary to the
shape-based entropy/taint scanners. Unlike a raw byte-matcher (e.g. YARA),
every signature is tested against both the raw bytes and the project decode
pipeline (base64/hex/url/entity/unicode decode, homoglyph fold, rot13), so
obfuscated known-malware is still caught. Rules ship in
`knowledge/signatures.json`; families are policy-selectable. OWASP LLM03
(supply chain) primary; LLM02.
- **AST — Python taint analysis** (`scanners/ast-taint-scanner.mjs`). Shells
out to a PARSE-ONLY `python3` helper (`scanners/lib/py-ast-taint.py`) for
variable-level, scope-aware taint analysis of Python skill code — higher
recall/precision than the ~70%-recall regex `taint-tracer.mjs`. The helper
only `ast.parse`s the target and never executes it, so analysing hostile
code is side-effect-free. Falls back to the regex tracer whenever `python3`
is unavailable, so the scan never hard-fails. OWASP LLM01, LLM02; AST02.
### Changed
- `TRG`/`SIG`/`AST` registered as valid finding prefixes
(`scanners/lib/output.mjs`); all three wired into the scan orchestrator and
policy loader. `knowledge/` added to the `package.json` `files` whitelist.

**v7.8.3 highlights** — Security/correctness patch, no feature changes. 47 verified fixes from the v7.8.1/v7.8.2 completion-review MEDIUM tier (52 findings triaged; 3 missing-detector feature-requests and 1 non-defect scoped out; the #11 persistence detector and #27 AST-taint f-string recall deferred to v8). No CRITICAL/HIGH — every review-claimed HIGH downgraded to MEDIUM on re-verification. Supply-chain gate bypasses closed (npm bare-install blocklist skip, nested-key name derivation, yarn.lock false-BLOCK + Yarn Berry miss, `pip audit`→`pip-audit`); pathguard now covers `Edit`; HTML-pattern ReDoS (28s→4ms) and an MCP-stdout memory-exhaustion DoS fixed; toxic-flow/TRG false positives and a bare-`if:` Dependabot-spoof false negative fixed; YAML block-scalar key-leak and embedded-base64→SIG decode closed; docs/counts synced (14 orchestrated scanners, 16 posture categories, 72 red-team scenarios, 2013 tests).
**v7.8.2 highlights** — Security patch, no feature changes. Five defects from the v7.8.1 completion review, four sharing one failure mode: **the check reported success without running**. (1) `hooks/scripts/pre-bash-destructive.mjs` did not block `rm -rf /` or `rm -rf ~` — the target alternation `(?:\/|~|\$HOME)\b` ended in a word boundary that cannot hold after `/` or `~` at end-of-command, so the bare forms the rule is named for fell through to WARN (exit 0, command executed) while `/etc` and `$HOME` blocked normally, making the rule look functional from either end. (2) `scanners/entropy-scanner.mjs` matched its test/fixture suppression against the **absolute** path, so any ancestor directory named `test`/`spec`/`fixture`/`mock` silenced every entropy finding in the target while still returning status `ok`; it now keys off the relative path. (3) `scanners/ide-extension-scanner.mjs` guarded only `parseVSCodeExtension`'s bare-`null` failure signal, not `parseIntelliJPlugin`'s truthy `{ manifest: null, warnings }`, so any malformed JetBrains plugin dereferenced `manifest.hasSignature`; the TypeError escaped `mapConcurrent`'s unguarded `Promise.all` and aborted the scan of every other installed extension. Guard widened + per-extension fault isolation. (4) `scanners/content-extractor.mjs` — the remote-scan injection boundary — detected obfuscated injections but did not strip them: a decoded-only `match[0]` never occurs in the raw text, so the literal replace was a silent no-op and the payload reached the agent verbatim via `sanitized_content` alongside a finding announcing it. Removal is now line-level; unattributable multi-line payloads carry `unstripped: true`. This boundary had no direct test coverage before v7.8.2. (5) `scanners/lib/ide-extension-parser.mjs` emptied any plugin.xml field holding a character reference above `0x10FFFF` (`Number.isFinite` bounds nothing) — filed as HIGH, actually lower, since such a document is not well-formed XML.
**v7.8.1 highlights** — Security patch, no feature changes. Fixes a CRITICAL command injection in `scanners/auto-cleaner.mjs`: `validateContent()` syntax-checked candidate `.mjs`/`.js`/`.cjs` content via ``execSync(`node --check "${tmpPath}"`)``, where `tmpPath` derives from the **untrusted scanned-repo filename**. The v7.8.0 F-2 guard checks path containment but neither strips nor quotes shell metacharacters, so a file named ``x";<command>;".mjs`` closes the interpolated quote and injects a command; since `/security clean` runs live by default, scanning a hostile repository sufficed for arbitrary local command execution (live-PoC verified). Both subprocess sites — the syntax check and the CLI's inline scan-orchestrator fallback — now use `spawnSync` with an argv array, so no shell parses a path. Defense-in-depth: `applyFixes()` refuses findings whose `file` carries shell/control metacharacters, surfaced as `skipped`. `validateContent` is now exported so regression tests can drive the sink directly — the guard would otherwise mask a re-introduced shell.
**v7.8.0 highlights** — Three new deterministic deep-scan scanners (TRG/SIG/AST) targeting the skills/agents attack surface, each with its own finding prefix, OWASP/AST mapping, policy block, and graceful-skip behaviour. **TRG** (`scanners/trigger-scanner.mjs`) inspects command/agent/skill `name` + `description` frontmatter for activation-surface abuse — `TRG-shadow` (name collides with a built-in and intercepts it), `TRG-baiting` (maximally-activating phrases that bait indiscriminate invocation), `TRG-broad` (generic name + universal-applicability claim); descriptions pass the decode pipeline first so obfuscated baiting still trips (LLM06/AST04). **SIG** (`scanners/signature-scanner.mjs`) is a pure-Node known-malware *identity* engine (webshells, reverse shells, cryptominers, hacktools) that tests each signature against both raw bytes and the decode pipeline, so obfuscated known-malware a byte-matcher misses is still caught; rules in `knowledge/signatures.json` (LLM03/LLM02). **AST** (`scanners/ast-taint-scanner.mjs`) shells out to a PARSE-ONLY `python3` helper (`scanners/lib/py-ast-taint.py`) for scope-aware Python taint analysis, falling back to the regex `taint-tracer.mjs` when `python3` is absent; the helper only `ast.parse`s the target, never executes it (LLM01/LLM02/AST02). Built behind a security-fix gate (F-1/F-2/F-3 landed first). No existing scanner, hook, or command behaviour changes.
**v7.7.2 highlights** — Language consistency pass. Norwegian had crept into the playground UI strings, the canonical CLI renderer (`scripts/lib/report-renderers.mjs`), the HTML Report-step appended by all 18 skill commands, two agent prompts, and the marketplace + plugin README/CLAUDE.md state sections. Per the `~/.claude/CLAUDE.md` convention (English for code and documentation, Norwegian for dialog only), surface text was translated to English. Demo-state fixture content for the `dft-komplett-demo` project (intentional Norwegian persona) and regex alternations that match Norwegian-language report markdown (`/^high|^høy/`, `/resolution|løsning/`) were preserved. No scanner, hook, or behavior changes.

## Distribution
This plugin lives in the `ktg-plugin-marketplace` monorepo at `https://git.fromaitochitta.com/open/ktg-plugin-marketplace` under `plugins/llm-security/`. It is not published as a standalone repo — users install it via the Claude Code marketplace mechanism:
This plugin is its own repository at `https://git.fromaitochitta.com/open/llm-security`. It is distributed through the `ktg-plugin-marketplace` catalog, which is a **polyrepo**: the catalog (`catalog/.claude-plugin/marketplace.json`) holds no plugin source, only a `url` + `ref` pin per plugin, and each plugin repo is released independently by tag. Users install via the Claude Code marketplace mechanism:
```bash
claude plugin marketplace add https://git.fromaitochitta.com/open/ktg-plugin-marketplace.git
```
A version bump is therefore two-sided: tag `vX.Y.Z` in this repo, then bump the catalog's `ref` to the same tag.
Issues, bug reports, and security disclosures all route to the marketplace repo.

# Governance
How this marketplace is maintained, what you can expect from upstream, and how it's meant to be used.
## TL;DR
- Solo-maintained, AI-assisted development, MIT licensed.
- **Fork-and-own is the default model.** Upstream is a starting point, not a vendor.
- Issues welcome as signals. Pull requests are not accepted — see [Why no PRs](#pull-requests--no).
- No SLA. Best-effort bug fixes and security advisories. Breaking changes happen and are noted in each plugin's CHANGELOG.
---
## Can I trust this?
Be honest with yourself about what you're adopting:
- **One maintainer.** If I get hit by a bus, the bus wins. The repos stay up under MIT, but no one owes you a fix.
- **AI-generated code with human review.** Every plugin is built through dialog-driven development with Claude Code. I read, test, and judge the output before it ships, but I'm not auditing every line the way a security firm would. Treat it accordingly.
- **No commercial interests.** I'm not selling a SaaS, not steering you toward a paid tier, not collecting telemetry. The plugins run locally in your Claude Code installation.
- **MIT licensed.** Fork it, modify it, ship it under your own name.
If you work somewhere that needs vendor accountability, support contracts, or signed assurances — **this isn't that.** Use it as a reference implementation, fork it into your own organization, and own the result.
---
## How this is meant to be used
### Fork-and-own
The intended workflow:
1. **Fork** the marketplace (or a single plugin) into your own organization or namespace.
2. **Tailor** it to your context — terminology, integrations, cycle lengths, regulatory framing, whatever doesn't fit out of the box.
3. **Maintain it yourself.** Treat your fork as the canonical version for your team.
4. **Watch upstream selectively.** Cherry-pick changes that help, ignore changes that don't. There's no obligation to stay in sync.
This isn't a workaround for not accepting PRs. It's the actual recommended adoption pattern, especially for plugins like `okr` and `ms-ai-architect` where every Norwegian public sector organization will need its own tildelingsbrev mappings, terminology, and integrations. A central "one true plugin" would be wrong for everyone.
### What to change first when you fork
Each plugin differs, but the common edits are:
- **Identity** — rename the plugin, replace authorship, update README.
- **External integrations** — issue trackers, knowledge bases, dashboards, observability backends. The plugins ship as starting points, not pre-wired. Every organization must configure its own integrations.
- **Norwegian-specific framing** — relevant for `okr` and `ms-ai-architect`. Other plugins are jurisdiction-neutral. Rewrite for your jurisdiction if you're outside Norway.
- **Reference docs** — the knowledge base in each plugin reflects my reading. Replace with your organization's authoritative sources.
- **Hooks and policies** — security thresholds, blocked commands, and audit gates are tuned to my taste. Tune them to yours.
### Staying current with upstream
If you want to pull in upstream changes later:
- **Cherry-pick, don't merge.** Each plugin moves independently and breaking changes land without ceremony.
- **Read the CHANGELOG first.** Every plugin has one.
- **Keep your customizations in clearly-named files.** The harder upstream is to merge cleanly, the more painful staying current becomes. A `local/` directory or `*.local.md` convention helps.
---
## What upstream provides
| | What I do | What I don't |
|---|---|---|
| **Bug fixes** | Best-effort when I notice or get a clear report | No SLA, no triage commitment |
| **Security issues** | Investigate within reasonable time, document in CHANGELOG | No CVE process, no embargo coordination |
| **New features** | When they fit my own usage | Not on request |
| **Norwegian public sector context** | Kept current as long as the project lives | If I lose interest or change jobs, the framing freezes |
| **Breaking changes** | Documented in CHANGELOG | They happen — version pin if you need stability |
| **Compatibility** | Tracked against current Claude Code releases | No long-term support branches |
If any of this is a dealbreaker — fork now, version-pin, and stop reading upstream.
---
## How to contribute
### Issues — yes, please
Issues are the most valuable thing you can send me:
- **Bug reports** with reproduction steps. Even a screenshot helps.
- **Use-case feedback.** "I tried to use this in my organization and X didn't fit" is genuinely useful, even if I can't fix it for you.
- **Pointers to better sources.** If you know a DFØ veileder, an NSM guideline, or an academic paper that contradicts what's in a knowledge base, tell me.
- **Security findings.** See each plugin's `SECURITY.md` for disclosure preference where one exists; otherwise email rather than open a public issue.
### Pull requests — no
This is deliberate, not laziness:
- **Solo review is a bottleneck.** Honest PR review takes me longer than rewriting from scratch. The math doesn't work.
- **Forks are where the value is.** The fork-and-own model means upstream consolidation isn't the point. Your organization's adaptations belong in your fork, not mine.
- **AI-generated code complicates provenance.** Every line here is produced through dialog with Claude Code, with me as the judge. Mixing in PRs from contributors with different processes and licensing assumptions creates a mess I'd rather not untangle.
If you've built something useful on top of a fork, **publish it under your own name and link back.** I'll happily list notable forks here once they exist.
### Notable forks
*(To be populated as forks emerge. If you've forked one of these plugins for production use, open an issue and I'll add a link.)*
---
## Relationship between plugins
These plugins are **independent**. Install one without the others, fork one without the others. They share conventions (slash command naming, hook patterns, AI-generated disclosure) but no runtime dependencies.
The marketplace is a **catalog**, not a suite. Don't fork the whole repo unless you actually want to maintain everything.
---
## Versioning and stability
- **Semantic versioning per plugin.** Each plugin has its own `CHANGELOG.md` and version number.
- **Breaking changes happen.** I bump the major version when they do, but I don't run an LTS branch.
- **Pin your version.** If stability matters more than features, install a specific version and stay there until you choose to upgrade.
---
## Public sector adoption notes
For Norwegian etater specifically:
- **DPIA-relevant data flows are documented in the relevant plugin README where applicable.** Read them before installation.
- **No data leaves your machine** beyond what Claude Code itself sends to Anthropic. The plugins themselves do not call external services unless you configure an integration.
- **Drøftingsplikt and ledelsesansvar** are not replaced by these tools. The `okr` plugin coaches; it does not decide. The `ms-ai-architect` plugin advises; it does not approve.
- **Choose your Claude deployment carefully.** claude.ai vs. API direct vs. Bedrock in EU region have different data residency profiles. The plugins don't choose for you.

Windows has no kernel-level sandbox equivalent. Run Claude Code inside WSL2 or Docker Desktop for full coverage; the git config hardening alone is sufficient against all known `.gitattributes` attack vectors.
**Where the OS sandbox layer actually holds:**
| Platform | Sandbox | How it works | Limitations |
|----------|---------|--------------|-------------|
| **macOS** | [`sandbox-exec`](https://keith.github.io/xcode-man-pages/sandbox-exec.1.html) | Seatbelt profile restricts file writes to only the per-clone temp dir | Deprecated by Apple but still functional; no replacement exists |
| **Linux** | [`bubblewrap`](https://github.com/containers/bubblewrap) (bwrap) | Read-only root bind mount + writable clone dir + namespace isolation | Requires the `bwrap` package. Works on Fedora/Arch; [fails on Ubuntu 24.04+](https://discourse.ubuntu.com/t/understanding-apparmor-user-namespace-restriction/58007) without admin AppArmor configuration |
| **Windows** | None available | Git config hardening only (layer 1) | See the Windows options below |
Sandbox availability is probe-tested at runtime. When none is available the plugin logs a WARN and proceeds with git config hardening only.
**Windows guidance:** Windows ships no CLI-level filesystem sandbox equivalent to `sandbox-exec` or `bwrap`. Every alternative needs either extra software or admin privileges:
| Option | Isolation level | Requirements |
|--------|-----------------|--------------|
| [Windows Sandbox](https://learn.microsoft.com/en-us/windows/security/application-security/application-isolation/windows-sandbox/windows-sandbox-overview) | Full VM (Hyper-V) | Windows Pro/Enterprise with Hyper-V enabled. GUI-oriented, not scriptable |
| [Docker Desktop](https://docs.docker.com/desktop/setup/install/windows-install/) | Container | Docker install. Best option for automated isolation |
| [WSL2](https://learn.microsoft.com/en-us/windows/wsl/install) | Linux VM | WSL2 install. `bwrap` is available inside it, subject to the Ubuntu 24.04+ caveat above |
| [AppContainer](https://learn.microsoft.com/en-us/windows/win32/secauthz/appcontainer-isolation) | Process sandbox | A native C++ helper binary — not practical to ship in a Node.js plugin |
Run Claude Code inside WSL2 or Docker Desktop for full coverage. The git config hardening alone is sufficient against all known `.gitattributes` attack vectors on every platform.
> **Why not Node.js `--permission`?** Node's [permission model](https://nodejs.org/api/permissions.html) restricts `fs` access *within* the Node process. It does not sandbox child processes, and `git` runs as a separate OS process — so it does not address this threat at all.

- **Compatibility** with new Claude Code releases
- **Knowledge-base refresh** (OWASP updates, new published research, new attack patterns)
- **Deprecation cleanup** — v8.0.0 removes the `LLM_SECURITY_*` env vars and `riskScoreV1` constant deprecated in v7.3.0
- **Deprecation cleanup** — v8.0.0 removed the four `LLM_SECURITY_*` mode env vars and `riskScoreV1`, both deprecated in v7.3.0 (see [Migration](#migrating-to-v800))

## Migrating to v8.0.0
v8.0.0 removes the four `LLM_SECURITY_*` configuration env-vars deprecated in
v7.3.0. Configuration moved to `.llm-security/policy.json`, which travels with
the repository instead of living in whoever's shell happened to launch Claude
Code.
**A removed variable is now inert.** It does not warn and it does not
configure — a project that relied on `LLM_SECURITY_INJECTION_MODE=off` silently
returns to the `block` default. Check for these before upgrading:
```bash
env | grep '^LLM_SECURITY_\(INJECTION_MODE\|TRIFECTA_MODE\|ESCALATION_WINDOW\|AUDIT_LOG\|DEPRECATION_QUIET\)='
grep -rn 'LLM_SECURITY_\(INJECTION_MODE\|TRIFECTA_MODE\|ESCALATION_WINDOW\|AUDIT_LOG\)' \
~/.zshenv ~/.bashrc .envrc .github/workflows/ 2>/dev/null
```
| Removed env-var | Policy key | Default |
|-----------------|------------|---------|
| `LLM_SECURITY_INJECTION_MODE` | `injection.mode` | `block` |
| `LLM_SECURITY_TRIFECTA_MODE` | `trifecta.mode` | `warn` |
| `LLM_SECURITY_ESCALATION_WINDOW` | `trifecta.escalation_window` | `5` |
| `LLM_SECURITY_AUDIT_LOG` | `audit.log_path` | unset (audit trail off) |
| `LLM_SECURITY_DEPRECATION_QUIET` | *(none)* | removed with the warning it silenced |
Translate each one you find into `.llm-security/policy.json`:
```json
{
"injection": { "mode": "block" },
"trifecta": { "mode": "warn", "escalation_window": 5 },
"audit": { "log_path": "/var/log/llm-security/audit.jsonl" }
}
```
**Unaffected.** Env-vars with no policy equivalent keep working and are not
part of this change: `LLM_SECURITY_PRECOMPACT_MODE`,
`LLM_SECURITY_PRECOMPACT_MAX_BYTES`, `LLM_SECURITY_UPDATE_CHECK`,
`LLM_SECURITY_MCP_CACHE_FILE`, `LLM_SECURITY_IDE_ROOTS`.
**Also removed:** `riskScoreV1()` in `scanners/lib/severity.mjs`, the v1
sum-and-cap scoring formula `@deprecated` since v7.0.0 and kept for reference
only. It had no callers in code or tests. `riskScore()` (v2, severity-dominated)
is unchanged, so no score, band, or verdict moves.

you — this forge has no Actions runner, so the only run that exists is the one
you start:
```bash
npm test # node --test 'tests/**/*.test.mjs'
```
Running `node scanners/scan-orchestrator.mjs .` on this plugin produces **0 findings (ALLOW)** with ~190 suppressions via `.llm-security-ignore`. Every suppression is explained — a security plugin that documents attack patterns, ships a malicious demo fixture, and tests against deliberately evil code will trigger its own scanners. The entropy scanner flags regex patterns in `knowledge/secrets-patterns.md`. The taint scanner flags `eval(user_input)` in test fixtures. The toxic flow analyzer flags the plugin's own commands that use Read+Bash. Remove the ignore file and re-run to see the unsuppressed picture.
The `examples/malicious-skill-demo/` directory contains a deliberately malicious "Project Health Dashboard" plugin and a [full security assessment](examples/malicious-skill-demo/security-assessment.md). The combined LLM + deterministic pipeline produced **85 findings** (24 critical, 24 high, 20 medium, 6 low, 11 info) and verdict **BLOCK 100/100** — both layers independently maxed the risk score. A human reviewing the plugin's `README.md` and `SKILL.md` would likely miss most of them; the Unicode Tag steganography is literally invisible.

| Version | Date | Highlights |
|---------|------|------------|
| **7.8.3** | 2026-07-18 | **Completion-review MEDIUM sweep — 47 verified fixes, no CRITICAL/HIGH.** 52 findings triaged (48 confirmed; 3 feature-requests + 1 non-defect scoped out; the #11 persistence detector and #27 AST-taint f-string recall deferred to v8). Supply-chain gate bypasses (npm bare-install blocklist skip, nested-key name derivation, yarn.lock false-BLOCK + Yarn Berry miss, `pip audit` no-op). Hook coverage (pathguard now `Edit|Write`; trifecta window no longer diluted by markers; pipe-to-shell interposition; bare provider-key patterns). Scanner robustness (HTML-pattern ReDoS 28s to 4ms; MCP-stdout memory exhaustion; VSIX redirect loop; scalar-policy TypeError; atomic cache writes). False positives/negatives (toxic-flow substring trifectas, TRG scoped-phrase FPs, leading-BOM HIGH, bare-`if:` Dependabot-spoof FN, reflog `reset` FP, diff duplicate-fingerprint mislabel, hex double-report). Parser divergence (YAML block-scalar key leak + indicators, ANSI-C octal/unicode, embedded-base64 to SIG, `.env.local` discovery). Docs consistency (scanner count 14, posture 16, red-team 72, SARIF version, dangling `ROADMAP.md`). Plus a live-protocol fix: `post-mcp-verify` now reads the PostToolUse `tool_response` field, so MCP-output injection scanning fires in live sessions. 2013 tests, 0 fail. |
| **7.8.2** | 2026-07-18 | **Silent-failure fixes from the completion review (HIGH).** Five defects, four sharing one failure mode: the check reported success without running. `hooks/scripts/pre-bash-destructive.mjs` did not block `rm -rf /` or `rm -rf ~` — the target alternation ended in a `\b` that cannot hold after a non-word character, so the bare forms the rule is named for fell through to WARN (exit 0, command executed) while `/etc` and `$HOME` blocked normally. `scanners/entropy-scanner.mjs` matched its test/fixture suppression against the **absolute** path, so any ancestor directory named `test`/`spec`/`fixture`/`mock` silenced every finding in the target and still returned status `ok`. `scanners/ide-extension-scanner.mjs` guarded only `parseVSCodeExtension`'s bare-`null` failure signal, not `parseIntelliJPlugin`'s truthy `{ manifest: null }`, so any malformed JetBrains plugin threw a TypeError that escaped `mapConcurrent`'s unguarded `Promise.all` and aborted the scan of every other extension. `scanners/content-extractor.mjs` detected obfuscated injections but did not remove them: a decoded-only `match[0]` never occurs in the raw text, so the literal replace was a no-op and the payload reached the LLM agent verbatim through `sanitized_content` — removal is now line-level, with unattributable multi-line payloads flagged `unstripped`. `scanners/lib/ide-extension-parser.mjs` emptied any plugin.xml field containing a character reference above `0x10FFFF`. No feature changes. 1901 tests, 0 fail. |
| **7.8.1** | 2026-07-18 | **Auto-cleaner command-injection fix (CRITICAL).** `scanners/auto-cleaner.mjs` syntax-checked candidate `.mjs`/`.js`/`.cjs` content via ``execSync(`node --check "${tmpPath}"`)``, where `tmpPath` derives from the untrusted scanned-repo **filename**. The v7.8.0 F-2 guard checks path containment but does not strip or quote shell metacharacters, so a file named ``x";<command>;".mjs`` closes the interpolated quote and injects a command — and `/security clean` runs live by default, making a hostile repository sufficient for arbitrary local command execution. Reproduced with a live PoC before the fix. Both subprocess sites (syntax check + the CLI scan-orchestrator fallback) now use `spawnSync` with an argv array, so no shell parses a path. Defense-in-depth: `applyFixes()` refuses findings whose `file` carries shell/control metacharacters, reported as `skipped`. Regression coverage is split across both layers so the guard cannot mask a re-introduced shell in the sink. No feature changes. 1865 tests, 0 fail. |
| **7.8.0** | 2026-06-20 | **TRG/SIG/AST deep-scan scanners.** Three new deterministic deep-scan scanners targeting the skills/agents attack surface, each with its own finding prefix, OWASP/AST mapping, policy block, and graceful-skip behaviour. **TRG** (`scanners/trigger-scanner.mjs`) inspects command/agent/skill `name` + `description` frontmatter for activation-surface abuse: `TRG-shadow` (name collides with a built-in and intercepts it), `TRG-baiting` (maximally-activating phrases that bait indiscriminate invocation), `TRG-broad` (generic name + universal-applicability claim); descriptions pass the decode pipeline first so obfuscated baiting still trips (LLM06/AST04). **SIG** (`scanners/signature-scanner.mjs`) is a pure-Node known-malware *identity* engine (webshells, reverse shells, cryptominers, hacktools) that tests each signature against both raw bytes and the decode pipeline (base64/hex/url/entity/unicode, homoglyph fold, rot13), so obfuscated known-malware a byte-matcher misses is still caught; rules ship in `knowledge/signatures.json` (LLM03/LLM02). **AST** (`scanners/ast-taint-scanner.mjs`) shells out to a PARSE-ONLY `python3` helper (`scanners/lib/py-ast-taint.py`) for variable-level, scope-aware Python taint analysis — higher recall than the ~70% regex `taint-tracer.mjs` — and falls back to the regex tracer when `python3` is unavailable, so the scan never hard-fails; the helper only `ast.parse`s the target and never executes it (LLM01/LLM02/AST02). Built behind a security-fix gate (F-1/F-2/F-3 shell-injection + path-traversal fixes landed first). 1863 tests, 0 fail. |
| **7.7.2** | 2026-05-19 | **Language consistency pass.** Norwegian had crept into surface text across v7.5-v7.7. Per the `~/.claude/CLAUDE.md` convention (English for code and documentation, Norwegian for dialog only), this release translates: the HTML Report-step appended by all 18 skill commands, the canonical CLI renderer `scripts/lib/report-renderers.mjs` (display strings + JS comments), the playground UI strings, the `skill-scanner-agent` and `mcp-scanner-agent` system prompts, the Recent versions table and playground architecture prose in this README, the v7.7.x highlights in `CLAUDE.md`, and the llm-security entries in the marketplace root `README.md` + `CLAUDE.md`, plus six table cells in `docs/scanner-reference.md`. Demo-state fixture content for the `dft-komplett-demo` project (intentional Norwegian persona) and regex alternations that match Norwegian-language report markdown (`/^high\|^høy/`, `/resolution\|løsning/`) were preserved. No scanner, hook, or behavior changes — purely surface text. |
| **7.7.1** | 2026-05-18 | **Playground UX strip.** Operator feedback immediately after v7.7.0: the home surface led with three project tracks (Re-onboard / New project / Command catalog) even though the catalog was the important entry point. Minimum strip delivered as three atomic commits (`b732eee` + `2a6f73f` + `81b7beb`): (1) the router always forces `activeSurface = 'catalog'` (the onboarding/home/project render functions are preserved in source but no longer routable); (2) the topbar `Home` and `Re-onboard` buttons removed, `Catalog` retained; (3) the breadcrumb org-name (`shared.organization.name` from demo state) replaced with a static `llm-security` neutral scope anchor. Fix: the hardcoded `'Plugin v7.6.1'` on line 6933 of `renderHome` (template literal not caught by the v7.7.0 grep) was synced. The onboarding concept is documented as a v7.8.0 candidate (per-command context injection) in `ROADMAP.md`. No scanner or hook behavior changes. |

| **7.7.0** | 2026-05-18 | **HTML report for all 18 skill commands.** Every `/security <cmd>` that produces a report now prints a clickable `file://` link to a self-contained HTML version. Delivered across 5 sessions. (1) Playground catalog list-view + builder-pane with a copy button. (2) Playground project-surface cleanup (stub-screen handling, topbar split). (3) The 18 inline parsers + renderers in the playground HTML were moved to a canonical ESM module `scripts/lib/report-renderers.mjs` (the playground keeps a bit-identical inline copy since ESM `import` does not work from `file://`). (4) New zero-dep CLI `scripts/render-report.mjs` — stdin/file/stdout mode, kebab→camel commandId routing, inlines 6 DS stylesheets + a local `.report-table` CSS, ~140 KB self-contained HTML, system-font fallback, absolute `file://` paths for Ghostty cmd-click. (5) All 18 skills wired (4 in session 4: scan/audit/posture/deep-scan; 14 in session 5: plugin-audit/mcp-audit/mcp-inspect/ide-scan/supply-check/dashboard/pre-deploy/diff/watch/registry/clean/harden/threat-model/red-team). Output: `reports/<command>-<YYYYMMDD-HHmmss>.html` relative to CWD. No scanner or hook behavior changes — purely additive. |
| **7.6.1** | 2026-05-06 | **Playground v7.6.0 visual patch.** Six bugs caught during maintainer verification in the browser. All were mismatches between DS classes and renderer usage (or missing DS implementations the playground assumed existed). (1) `renderFindingsBlock` used the `.findings` outer class, which is the DS 2-column list+detail grid → replaced with `<section class="report-meta">` + the correct `findings__list > findings__group` pattern. (2) `.report-table` was missing entirely from the DS but used in 7+ renderers → local CSS implementation in the playground HTML. (3) `renderPreDeploy` traffic-lights used `.sm-card__grade` (28×28 px for one A-F letter) for "PASS"/"PASS-WITH-NOTES"/"FAIL" → replaced with a width-adapting status pill. (4) Threat-model matrix bubbles were not clickable → `<button>` with `data-threat-id` + click handler that scrolls to the Threats table. (5) Radar labels overlapped at 6+ axes → SVG 280→380, R 105→125, dynamic `text-anchor` (start/end/middle) based on horizontal position. (6) `recommendation-card__body` overflow on long text → `overflow-wrap: anywhere`. 4/4 fix-specific smoke tests + 18/18 renderer regression passing. No scanner or hook behavior changes — purely additive surface. |
| **7.6.0** | 2026-05-06 | **Playground Tier 3 reference case.** The playground (`playground/llm-security-playground.html`) raised to a visually and structurally complete reference for the `shared/playground-design-system/` Tier 3 supplement. 8 new DS components integrated into the 18 report renderers: `tfa-flow` + `tfa-leg` + `tfa-arrow` (lethal trifecta chain with `<button>` elements + ARIA), `mat-ladder` + `mat-step` (5-step maturity ladder with thresholds 0/25/50/75/95% PASS), `suppressed-group` (narrative audit from `summary.narrative_audit.suppressed_findings`), `codepoint-reveal` + `cp-tag`/`cp-zw`/`cp-bidi` (Unicode steganography side-by-side), `top-risks` + `top-risk[data-severity]` (ranked top-findings listing, semantic `<ol>`), `recommendation-card[data-severity]` (severity-tinted advisory on `clean`/`harden`/`audit`/`posture`/`pre-deploy`/`plugin-audit`), `risk-meter` (0-100 band visualization across 5 archetypes), `card--severity-{level}` (severity-color modifier on findings cards). Wave 1: `badge--scope-security` (identity chip), `verdict-pill-lg` (DS Tier 3 pill), `form-progress` + `fp-step` (onboarding wizard). Removed ~30 duplicate CSS declarations (DS wins the cascade). 5 new DS helpers + `mapSeverityToCardLevel` + `parseNarrativeAudit`. File size 10209 → 10677 lines.

# Plugin review — llm-security v7.7.2 (2026-06-20)
> Full-depth review (part of the marketplace-wide sweep; pilot was okr). Tooling: config-audit
> v5.4.0 scanners (from source) + llm-security posture assessor + structure/version checks.
> Read-only; this file is the only artifact.
## Verdict
**Grade B− — exceptionally disciplined design undermined by one true zero-interaction RCE in a
default scanner.** At the design level this is one of the most security-conscious plugins in the
marketplace (untrusted targets treated as data behind an evidence-package boundary, least-privilege
agents, backup/dry-run-gated mutations, inert stdin-isolated fixtures, no eval/unsafe-deser). But
the scanner code does not hold itself to the standard it enforces on others: three shell/path sinks
trust untrusted strings, one of them a **critical** RCE.
> ⚠️ **F-1 is a CRITICAL, zero-interaction RCE, reproduced end-to-end. Treat as fix-before-anything.**
## Results by dimension

## Findings
| ID | Severity | Location | Finding |
|----|----------|----------|---------|
| F-1 | **CRITICAL** | `scanners/git-forensics.mjs:59-66` (sinks :211,:223,:231,:564) | `git()` runs `execSync(\`git ${cmd}\`)` (shell string) with attacker-controlled filenames from the scanned repo interpolated in. `gitScan` is in the **default** SCANNERS array, and `/security scan <github-url>` clones a user-supplied repo then scans it. A hostile repo with a file named `commands/$(touch INJECTED).md` runs **arbitrary code on the analyst's machine with no install and no confirmation** (forensics runs outside the clone sandbox). Reproduced end-to-end. **Fix:** convert `git()` to `spawnSync('git', [...argArray], {cwd})` — every call site already has discrete tokens. |
| F-2 | High | `scanners/auto-cleaner.mjs:776,878-881` | `resolve(targetPath, f.file)` with no containment check; `f.file` from findings JSON (untrusted repo filenames, or an attacker-chosen `--findings` file). `file: "../../../.claude/settings.json"` writes outside the scanned tree. **Fix:** assert `absPath === targetPath || absPath.startsWith(targetPath + sep)` before write. |
| F-3 | High | `hooks/scripts/pre-install-supply-chain.mjs:254` → `supply-chain-data.mjs:221-227` | `execSafe(\`npm view ${spec} --json\`)` is `execSync` (shell). A spec like `foo;touch /tmp/X` survives parsing and reaches the shell, firing on **PreToolUse(Bash) before** the user's npm install — so it executes pre-confirmation even if the user then denies. **Fix:** `spawnSync('npm', ['view', spec, '--json'])` or validate spec `^[@/A-Za-z0-9._-]+$`. |
| F-4 | Low | `mcp-live-inspect.mjs:296` | Spawns the scanned target's declared MCP command (array-arg, no metachar injection). By-design for `/security mcp-inspect`, but scanning an untrusted target launches attacker-declared processes. Suggest a confirm before spawning servers from a non-home target. |
| F-5/F-6 | Low (hygiene) | repo root | Two stray committed artifacts: `--json` (0-byte redirect husk) and `.orphaned_at`. Inert; `git rm`. |
**Cleared (so they aren't re-flagged):** malicious fixtures (stdin-isolated to subprocess, never
shell-executed), zip-extract (zip-slip + bomb guards), git-clone (hooksPath=/dev/null,
protocol.file.allow=never, array args, sandbox), vsix-fetch (HTTPS host allowlist), dep-auditor
(fixed strings), all 9 hooks (fail-open, advisory-only). Agents least-privilege.
## Priority
The three shell/path sinks (F-1/F-2/F-3) share one root cause — trusting untrusted strings at a
subprocess/filesystem sink — and all have small, localized `execSync→spawnSync(array)` / containment
fixes. Fixing them lifts the plugin from B− to a solid A−. **F-1 should be fixed before the next
`/security scan` of any untrusted repo URL.**

Lib: `mcp-description-cache.mjs` — caches MCP tool descriptions in `~/.cache/llm-security/mcp-descriptions.json`, detects per-update drift via Levenshtein (>10% = alert), 7-day TTL. v7.3.0 (E14) adds a sticky baseline slot per tool plus a 10-event rolling history; cumulative drift = `levenshtein(current, baseline) / max(|current|,|baseline|)`. When ratio ≥ `mcp.cumulative_drift_threshold` (default 0.25), emits `mcp-cumulative-drift` advisory through `post-mcp-verify.mjs`. Baseline survives TTL purge so slow-burn drift is preserved across the 7-day window. `clearBaseline(tool?)` exposed for the `/security mcp-baseline-reset` command. `LLM_SECURITY_MCP_CACHE_FILE` env var overrides the cache path for testing.

Toxic-flow (TFA) is a post-processing correlator that runs LAST — detects "lethal trifecta" (untrusted input + sensitive data access + exfiltration sink) by correlating output from prior scanners.
Trigger-abuse (TRG) inspects command/agent/skill `name`+`description` frontmatter for activation-surface abuse: built-in shadowing (a name colliding with a built-in tool), activation baiting (maximally-activating description phrases), and overly broad triggers (generic name + universal-applicability claim → HIGH). Descriptions are run through the decode pipeline (zero-width strip, homoglyph fold, `normalizeForScan`) so obfuscated baiting still trips. Policy: `trg` section (`baiting_phrases`, `builtin_names`, `broad_single_words`). OWASP: LLM06, AST04.
Signature (SIG) is a known-bad-identity engine: a small, high-confidence, family-grouped ruleset (`signatures/malware-signatures.json` in the vendored commons, built by `scanners/lib/malware-signatures.mjs` — webshell, reverse_shell, cryptominer, hacktool) tested against each file's decode pipeline (`normalizeForScan`/`foldHomoglyphs`/`rot13`), so obfuscated known-malware that a raw byte-matcher misses is still caught. Path-excludes `knowledge/`, `tests/`, `docs/`, `node_modules/`, and `scanners/commons/` (the vendored ruleset describes the malware it detects, so SIG matched its own detection data) — each matched anywhere in the relative path, which knowingly blinds SIG to a payload planted under such a directory in a scanned repo. Policy: `sig.enabled_families`. OWASP: LLM03, LLM02.
AST-taint (AST) shells out to a PARSE-ONLY python3 helper (`scanners/lib/py-ast-taint.py`) for scope-aware, variable-level Python taint analysis (sources → sinks), with graceful fallback to the regex taint-tracer when python3 is absent. The helper only `ast.parse`s the target — it never executes it. 5s timeout per file. Policy: `ast` section (`enabled`, `python_path`, `timeout_ms`). OWASP: LLM01, LLM02, AST02.

# Security fix brief — 3 shell/path injection sinks (2026-06-20)

> `docs/review-2026-06-20.md`). Do this **after the current active session finishes** — do not
> interleave with in-flight work.
>
> **Disclosure hold:** the review report (`review-2026-06-20.md`, commit `738770e`) and this brief
> are committed locally but **NOT pushed**, because F-1 is a working RCE with a reproduction
> payload. **Push both only together with the F-1 fix** — never publish the RCE detail to a public
> remote while it is still exploitable.
## Priority order
| # | Severity | Fix first? |
|---|----------|-----------|
| F-1 | **CRITICAL** (zero-interaction RCE) | **YES — before any `/security scan` of an untrusted repo URL** |
| F-2 | HIGH (arbitrary file write) | yes |
| F-3 | HIGH (command injection, pre-confirmation) | yes |
| F-4 | LOW | optional |
| F-5/F-6 | LOW (hygiene) | optional |
## Common root cause
F-1/F-2/F-3 all trust untrusted strings at a subprocess/filesystem sink. The fix family is the same:
**`execSync(shell-string)` → `spawnSync('cmd', [...argArray])`** (no shell), or input containment.
Every affected call site already has discrete tokens, so the change is mechanical and localized.
## F-1 — CRITICAL — `scanners/git-forensics.mjs`
- **Sink:** `git()` at `:59-66` runs `execSync(\`git ${cmd}\`)` (shell string). Attacker-controlled
filenames from the scanned repo (`git ls-files` :202, `git log --name-only` :549) are interpolated
at **:211, :223, :231, :564**. `"${relFile}"` quoting at :211 does NOT stop `$(...)`/backticks;
:223/:231 are unquoted.
- **Why critical:** `gitScan` is in the **default** SCANNERS array (`scan-orchestrator.mjs:119`), and
`commands/scan.md` clones a user-supplied GitHub URL then scans it. A hostile repo containing a
file named `commands/$(touch INJECTED).md` runs arbitrary code on the analyst's machine on
`/security scan <url>` — no install, no confirmation. Forensics runs **outside** the git-clone
OS-sandbox (that wraps only the clone), so it runs unsandboxed on all platforms. Reproduced
end-to-end.
- **Fix:** convert `git()` to `spawnSync('git', [...argArray], {cwd})` and pass each call site's
tokens as an array (they are already discrete). No shell, no interpolation.
- **Verify:** add a test fixture repo with a file named `$(touch /tmp/pwned).md`; assert the scan
completes and `/tmp/pwned` is NOT created. (TDD: write the failing repro first.)
## F-2 — HIGH — `scanners/auto-cleaner.mjs`
- **Sink:** `:776` `resolve(targetPath, f.file)` with no containment check; written at `:878-881`.
`f.file` comes from findings JSON (untrusted repo filenames, or a fully attacker-chosen
`--findings` file), so `file: "../../../.claude/settings.json"` writes outside the scanned tree.
- **Fix:** before writing, assert `absPath === targetPath || absPath.startsWith(targetPath + sep)`;
otherwise skip + report.
- **Verify:** a finding with `file: "../escape.txt"` must be refused, not written.
## F-3 — HIGH — `hooks/scripts/pre-install-supply-chain.mjs` → `supply-chain-data.mjs`
- **Sink:** `pre-install-supply-chain.mjs:254` → `inspectNpmPackage` calls
`execSafe(\`npm view ${spec} --json\`)`; `execSafe` (`supply-chain-data.mjs:221-227`) is
`execSync` (shell). A spec like `foo;touch /tmp/X` survives `extractNpmPackages`+`parseSpec`
(name=`foo;touch`) and reaches the shell. It fires on **PreToolUse(Bash) before** the user's npm
install — so it executes pre-confirmation even if the user then denies the Bash call.
- **Fix:** `spawnSync('npm', ['view', spec, '--json'])`, or validate `spec` against
`^[@/A-Za-z0-9._-]+$` before use. (pip/go/OSV paths already use fetch/array args — only the npm
`npm view` path shells out.)
- **Verify:** a package spec `foo;touch /tmp/X` must not execute the `touch`.
## F-4 / F-5 / F-6 — LOW
- **F-4** `mcp-live-inspect.mjs:296` spawns the scanned target's declared MCP command (array-arg, no
metachar injection). By-design for `/security mcp-inspect`, but scanning an untrusted target
launches attacker-declared processes — add a confirm before spawning servers from a non-home target.
- **F-5/F-6** two stray committed root artifacts: `--json` (0-byte redirect husk) and `.orphaned_at`.
Inert; `git rm` them.
## Closing gates (when fixing)
- TDD per fix (repro → red → green). Full `node --test` suite green.
- gitleaks clean. Re-run the F-1 repro to confirm the sink is closed.
- **Then** push: the F-1 fix commit + `review-2026-06-20.md` + this brief, together. After that the
disclosure hold is lifted.
- Fixing F-1/F-2/F-3 lifts the plugin from B− to a solid A−.

## v7.8.2 — Silent-failure fixes from the completion review (HIGH)
Security patch covering five defects found in the v7.8.1 completion review. No
feature changes; full suite green at 1901/0 (1865 + 36 new regression tests).
The common thread in four of the five is **silent failure**: the scanner or
hook reported success while the check it is named for did not run. That is the
worst failure mode for a security tool, because a clean report is
indistinguishable from a clean target.
- **`hooks/scripts/pre-bash-destructive.mjs`** — the rule named "Filesystem
root destruction (rm -rf /)" did not block `rm -rf /`. Its target
alternation `(?:\/|~|\$HOME)\b` ended in a word-boundary assertion, which
cannot hold after `/` or `~` at end-of-command. Measured: `rm -rf /`,
`rm -rf ~`, `rm -rf /*`, `rm -fr /` and `sudo rm -rf /` all fell through to
WARN — advisory only, exit 0, command executed. `rm -rf $HOME` and
`rm -rf /usr` were blocked, which is why the gap survived: the rule looked
functional from either end. The `\b` now sits on the `$HOME` alternative
alone, so `$HOMEDIR` is still not swallowed. The prior test file had encoded
the defect as expected behaviour, with a NOTE attributing it to merged `-rf`
flags — a misdiagnosis, since `rm -rf /etc` blocks fine with merged flags.
- **`scanners/entropy-scanner.mjs`** — the "test fixtures intentionally contain
example secrets" suppression matched against the **absolute** path. Any
ancestor directory name containing `test`, `spec`, `fixture` or `mock`
therefore suppressed every entropy finding in the whole target: a repository
cloned into a CI workspace, or checked out beneath a folder named `testing`,
reported zero secrets with status `ok`. The rule now keys off the path
relative to the scan root, which was already computed and passed alongside
it. Genuine fixture suppression (a `*.test.mjs` file, a relative `tests/`
directory) is unchanged.
- **`scanners/ide-extension-scanner.mjs`** — `parseVSCodeExtension` signals
failure as bare `null`; `parseIntelliJPlugin` signals it as a **truthy**
`{ manifest: null, warnings }`. Only the former was guarded, so all five
JetBrains failure paths (no `lib/`, `lib/` not a directory, `lib/`
unreadable, no jars, no extractable jar) reached `manifest.hasSignature` and
threw. `mapConcurrent` awaited without a per-item catch, so `Promise.all`
rejected and the entire ide-scan aborted — one malformed plugin directory
took down the scan of every other installed extension, including, in an
audit context, a plugin that is malformed precisely because it is hostile.
- **`scanners/content-extractor.mjs`** — this is the remote-scan indirection
layer: agents are supposed to see a sanitized evidence package, never raw
hostile content. `stripInjection` scanned the raw text *and* its decoded
form, but removed matches with `sanitized.replace(match[0], …)` against the
raw text only. A decoded-only `match[0]` does not occur in the raw text by
construction, so the replace silently did nothing: the payload was handed to
the agent verbatim through `sanitized_content` while the report announced a
critical injection. Removal now redacts the offending source line, since
decoding is not length-preserving and decoded offsets cannot be mapped back.
A payload split across several lines still cannot be attributed; those
findings carry `unstripped: true` instead of failing quietly. Whole-file
redaction was rejected — `normalizeForScan` base64-decodes any long blob, so
a benign asset could blank a file's entire evidence.
- **`scanners/lib/ide-extension-parser.mjs`** — `decodeEntities` guarded
`parseInt` with `Number.isFinite`, which bounds nothing, so a character
reference above `0x10FFFF` raised `RangeError` in `String.fromCodePoint`.
Contrary to how this was filed, the documented no-throw contract held: the
per-field `safe()` wrapper catches it. The real effect was quieter — the
field was replaced with `''`, so a `<name>` carrying one such reference
parsed as an empty name and name-based checks (JetBrains typosquat
detection) ran against nothing. Severity is below HIGH: a document with a
code point above `0x10FFFF` is not well-formed XML, so IntelliJ would reject
the plugin as well. Undecodable references are now left literal.
## v7.8.1 — Auto-cleaner command-injection fix (CRITICAL)
Security patch for a CRITICAL defect introduced with the v7.8.0 auto-cleaner
hardening pass. No feature changes; full suite green at 1865/0.
`scanners/auto-cleaner.mjs` validated candidate `.mjs`/`.js`/`.cjs` content by
shelling out to ``node --check "${tmpPath}"`` via `execSync`. `tmpPath` is
derived from the finding's `file` field — an untrusted scanned-repo filename.
The F-2 containment guard that landed in v7.8.0 verifies the resolved path
stays inside the scanned tree, but performs no shell-metacharacter handling, so
a filename whose `"` terminates the interpolated quote injects a second
command. Because `/security clean` runs in live mode by default, scanning a
hostile repository was sufficient to execute attacker-chosen commands locally.
The defect was reproduced with a live proof-of-concept before being fixed.
Both subprocess sites now use `spawnSync` with an argv array — the syntax check
and the CLI's inline scan-orchestrator fallback — so no shell interprets a path.
As defense-in-depth, `applyFixes()` additionally refuses any finding whose
`file` carries shell or control metacharacters, surfacing it as `skipped`.
Regression coverage is deliberately split across both layers
(`tests/scanners/auto-cleaner-rce.test.mjs`): one test drives `validateContent`
directly to prove the shell is gone, because the metacharacter guard would
otherwise stop the hostile input before it reached the sink and the test would
pass without testing the fix.
## v7.8.0 — Trigger, signature, and AST-taint scanners
Three new deterministic deep-scan scanners (TRG/SIG/AST), each with its own
finding prefix, OWASP/AST mapping, policy block, fixtures, and graceful-skip
behaviour. They target the skills/agents activation and code surface that the
permission and shape-based scanners do not cover. Built behind a security-fix
gate — the F-1/F-2/F-3 shell-injection and path-traversal fixes landed first.
No existing scanner, hook, or command behaviour changes; full suite green
(1863 tests, 0 fail).
- **TRG — trigger/activation-abuse** (`scanners/trigger-scanner.mjs`).
Inspects command/agent/skill `name` + `description` frontmatter for three
activation-surface abuses: `TRG-shadow` (name collides with a built-in
command/tool and intercepts it), `TRG-baiting` (description uses
maximally-activating phrases — "anything", "always", "all files" — to bait
indiscriminate invocation), and `TRG-broad` (a generic name plus a
universal-applicability claim, so the unit auto-activates beyond its stated
purpose). Skills/agents auto-activate on their description, so this is a
skill-native surface not covered by the permission or taint scanners.
Descriptions pass through the decode pipeline (zero-width strip → homoglyph
fold → `normalizeForScan`) first, so obfuscated baiting still trips.
Thresholds and the phrase/built-in lists are overridable via
`.llm-security/policy.json` (`trg`). OWASP LLM06 (excessive agency); AST04.
- **SIG — known-bad-identity signatures** (`scanners/signature-scanner.mjs`).
A pure-Node signature engine for known-malware *identity* — webshells,
reverse shells, cryptominers, hacktools — complementary to the shape-based
entropy/taint scanners. Unlike a raw byte-matcher (e.g. YARA), every
signature is tested against both the raw bytes and the project decode
pipeline (base64/hex/url/entity/unicode decode, homoglyph fold, rot13), so
obfuscated known-malware a byte-matcher misses is still caught. Rules ship
in `knowledge/signatures.json`; families are policy-selectable. OWASP LLM03
(supply chain) primary; LLM02.
- **AST — Python taint analysis** (`scanners/ast-taint-scanner.mjs`). Shells
out to a PARSE-ONLY `python3` helper (`scanners/lib/py-ast-taint.py`) for
variable-level, scope-aware taint analysis of Python skill code — higher
recall/precision than the ~70%-recall regex `taint-tracer.mjs`. The helper
only `ast.parse`s the target and never executes it, so analysing hostile
code is side-effect-free. Falls back to the regex tracer whenever `python3`
is unavailable, so the scan never hard-fails. OWASP LLM01, LLM02; AST02.
Packaging/wiring: `TRG`/`SIG`/`AST` registered as valid finding prefixes
(`scanners/lib/output.mjs`); all three wired into the scan orchestrator and
policy loader; `knowledge/` added to the `package.json` `files` whitelist.

# Compliance Mapping
Maps the llm-security plugin's 13 posture categories and mitigation controls to three enterprise compliance frameworks: EU AI Act, NIST AI RMF, and ISO 42001.
Maps the llm-security plugin's 13 code-level posture categories and mitigation controls to three enterprise compliance frameworks: EU AI Act, NIST AI RMF, and ISO 42001.
Used by `posture-assessor-agent` and compliance-aware posture categories (14-16) to evaluate framework alignment.
## How to Read This Matrix
- **Plugin Control:** One of the 13 posture scanner categories
- **Plugin Control:** One of the 13 code-level posture categories (1-13). The three governance categories (14-16) are consumers of this matrix, not rows in it
- **Control Type:** Automated (hooks), Configured (settings), Advisory (scans/audits)
- **EU AI Act:** Regulation (EU) 2024/1689 article(s) the control satisfies
- **NIST AI RMF:** AI 100-1 function(s) the control supports (Govern, Map, Measure, Manage)

// ast-taint-scanner.mjs — AST: Python taint analysis via a shipped python3 helper

// The regex taint-tracer (taint-tracer.mjs) has ~70% recall and no scope or
// cross-statement awareness. This scanner shells out to a PARSE-ONLY python3
// helper (scanners/lib/py-ast-taint.py) that does variable-level, scope-aware
// taint analysis of Python skill code — higher recall/precision — and falls
// back gracefully to the regex tracer whenever python3 is unavailable.
//
// The helper only PARSES the target (ast.parse); it never executes it, so
// analysing hostile code is side-effect-free.
//
// OWASP coverage: LLM01 (prompt injection / untrusted input to action),
// LLM02 (sensitive information disclosure); AST02 (skills framework).
// Zero external dependencies — Node.js builtins only. python3 is optional.

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this
project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
Versioning note: the repository tag versions **the contract** (file set, key names,
case ids, disposition semantics). Each JSON file additionally carries its own
`"version"` field, bumped when that file changes.
## [0.4.3] — 2026-08-11
**No fixture, id or `expected.json` moved — a runtime that passes `0.4.2` passes `0.4.3`
unchanged. What changed is a claim this repository made about a runtime it does not own, and the
claim was wrong on the day it was written.**
### Fixed
- `conformance/manifest.json` `0.3.2` → `0.3.4` — the `scope_planned.blockers` entry for
`codepoints/carriers.json` described the guard as emitting two stage-coupled labels per carrier,
"the same split for bidi and unicode-tag". The artifact-side label for tags is
`lexicon:unicode-tags-present`, emitted from `lexicon.py`, and `output.py` carries a comment
saying it deliberately does not repeat it there. **Wrong when written, not stale:** checked at
`e671edb` — the commit the sibling secret-egress blocker was measured against — where
`coverage.py` already asserted that label, and re-measured at `a59184b`.
The correction moves the blocker rather than removing it. The guard's `Finding` carries a
`detector` field beside `label`, and the prefix is that field's value: `detector="lexicon"` on
`lexicon:unicode-tags-present`, `"output"` on `output:zero-width-present`. **The prefix names
the detector, not the pipeline stage** — and for tags a single detector serves both entry
points, which is why there is no sixth `output:` label to find. "A commons id would have to be
invented stage-neutral" was never the problem. Six labels exist to adopt verbatim, the way the
83 lexicon ids were adopted from this same runtime's port.
What blocks adoption is measured and named instead, at llm-security `47905da`: `sanitize:`
asserts a strip that runtime does not perform (`scanners/unicode-scanner.mjs` exports one entry
point, `scan(targetPath, discovery)`, reporting presence with `scanner: 'UNI'`, a prose title
and no id); three of the six name a persist gate it does not have, which the corpus already has
a verdict for — §1.1 `not-applicable`, attaching to a declared **table** — but which
**publishing the alias is what takes away**: that runtime's suite walks each vendored file for
any node carrying `aliases.llm_security` and asserts every registered table is declared, so one
aliased carrier id forces `codepoints/carriers.json` into a declared set of what is today the
lexicon alone, obliging it to run all six cases and converting the three artifact-side ones into
failures; and the entry point pinned for it in `measurement.runtimes` (`scanForInjection`) does not
reach carriers at all, so carrier cases need a per-scope entry point this manifest expresses
nowhere. Both runtimes already build their carrier sets from `codepoints/carriers.json`, so the
divergence is in what a finding is *called* and where it can be *observed*, never in which code
points are carriers.
### Asked, not decided
- The three objections went to both runtimes over coord on 2026-08-11 as a decision request, each
asked the question only it can answer. **Nothing was minted.** A case id is contract surface
consumers pin against, and publishing a single carrier alias is itself irreversible — it widens
another runtime's declared table set by force of that runtime's own test suite. Minting first
would have made a proposal into a fait accompli. The manifest records the request, so a later
reader can tell "asked, unanswered" from "nobody asked".
- **A correction followed the request the same day, on our own error.** The request asserted that
the corpus had no third verdict for a case a runtime cannot reach. It has one — §1.1
`not-applicable` — and this repository wrote that section. The question was put before its own
normative spec was re-read; the follow-up says so to both runtimes and restates the choice as
mint-input-side-only, accept three standing failures, or publish a guard-only id space with no
`llm_security` alias at all.
## [0.4.2] — 2026-08-11
**No data file changed and no pattern moved.** A runtime that passes `0.4.1` passes `0.4.2`
unchanged; there is nothing here to re-measure. What the release adds is the rule set an outside
contributor could not previously read — including the reason the forge surface is shaped the way
it is.
### Added
- `CONVENTIONS.md` — the whole rule set a change here is held to, consolidated. **Not new
policy:** the charter lives in `CLAUDE.md`, the versioning and vendoring rules in `README.md`,
the reporting route in `SECURITY.md`, and the file conventions were visible only in the shape
of the files. Collected because a convention that exists only in the maintainer's head is not
one an outside reader can meet.
Two things in it were previously inferable at best. **Why pull requests are off:** this
repository is vendored into independent runtimes that pin a tag, so a change to detection data
changes what they *find*, and that has to be coordinated with each consumer **before it
exists** — which a merge button cannot do. `org-ops` reached that conclusion on 2026-08-11
from a README line, and the conclusion was right; this file is the ground it was missing.
**When a value may change:** the three mechanisms that have moved one so far — re-extraction,
retraction, and owner-directed authoring — each named with the `source_fidelity` key that
records it, and merit named explicitly as *not* on that list.
It also carries the four offline checks that stand in for the CI this organisation does not
have. Each was confirmed to go **red** on a violation, not merely green on a clean tree: a
JSON file with no `version`, a `spec/` file with no normative marker, and a planted `.sh` were
each detected. A check that cannot fail proves nothing. The checks are shell one-liners rather
than a script because a script would be `.sh`, and check 4 would fail on the tooling meant to
enforce it.
- `README.md` — a short **Contributing** section pointing at it, carrying the pull-request answer
inline so a reader who never opens the file still gets it. Same pattern the
**Reporting a wrong entry** section followed for `SECURITY.md` in `0.3.1`.
The four `v0.4.1` references in the install block and the layout table move to `v0.4.2`.
This closes the second half of what `org-ops` recorded as missing against the org standard on
2026-08-11. `SECURITY.md` was the first half, in `0.3.1`.
## [0.4.1] — 2026-08-11
**No data file changed and no pattern moved. A number this repository published was wrong, and
it was wrong in our favour's opposite direction — the corrected figures are larger.** A runtime
that passes `0.4.0` passes `0.4.1` unchanged.
### Fixed
- `docs/lexicon-port-divergence.md` (informative) — the ReDoS figures for
`hybrid-xss:iframe-src` read **~3× low**, and the Python `script-tag` figure at 32 000 chars
read ~4× low. Flagged by `llm-ingestion-pipeline-security` (coord, 2026-08-11T19:51:55Z), who
measured the row themselves rather than citing ours.
Their diagnosis was measurement surface — their composed `scan_lexicon()` against our
standalone regex. **Checked, and that is not the cause:** our standalone 100 000-char figure
(7.86 s) sits close to their composed 8.95 s, so the two surfaces differ by far less than the
error. Re-measured standalone, Python 3.14.0: `iframe-src` `[^>]*` is 822.7 ms at 32 000 chars
and 51 477.4 ms at 256 000, against the published 119.6 ms and 16 857 ms. The Python
`script-tag` figure at 256 000 chars *does* reproduce (5.44 s published, 5.22 s measured); the
one at 32 000 chars does not (0.021 s against 0.087 s).
The error ratios are not constant, so a single mis-sized input does not explain it, and the
original harness lived in a previous session's scratchpad and no longer exists. **The cause is
recorded as not diagnosable rather than guessed at.** The correction is a box in the document
carrying the re-measured table, and the superseded figures are struck in place rather than
quietly overwritten — a consumer who cited the old number needs to find out that they did.
Nothing about the `0.4.0` decision depends on this. Every corrected figure is larger, the
shape is unchanged (quadratic, ×4 per doubling), and both `[^><]*` forms remain flat under
both engines. The `0.4.0` entry below still quotes the old `iframe-src` figure; it is left as
published, because that section is the record of what was released.
## [0.4.0] — 2026-08-11
**Two detection values changed, by two different mechanisms, and the difference between those
mechanisms is the point of the release.** One pattern table was **re-extracted** from a pinned
upstream commit, the way every value in this repository has moved until now. Two lexicon rows were
**authored here at the source owner's direction**, which has never happened before and required a
reason that is not "we measured it and we were right."
A runtime that vendors this repository will see findings change. Any consumer asserting
byte-identity against `v0.3.0` goes red by construction — `lexicon/injection-lexicon.json` changed
pattern text. Ids, labels, aliases, family membership, case ids and every count are unchanged.
### Changed
- `lexicon/injection-lexicon.json` `0.7.0` → `0.8.0` — **`hybrid-xss:script-tag` and
`hybrid-xss:iframe-src` narrow their unbounded negated class from `[^>]*` to `[^><]*`.** Both
forms are quadratic in scan length on input that repeats the tag prefix and never supplies a
`>`: each occurrence is a match start and `[^>]*` scans to end of input from each one. Measured
in Node v25.8.2 at 16k / 32k / 64k / 128k / 256k chars — script-tag 32.65 / 113.36 / 479.02 /
1988.83 / **7772.25** ms, iframe-src 39.23 / 131.76 / 574.94 / 2469.55 / **9449.94** ms, ×4 per
doubling for both. Under `[^><]*` the same inputs cost 0.08–0.66 ms and 0.10–1.00 ms: flat, not
merely faster.
**Why this is not commons correcting seed data.** The dependency direction inverted. As of
`llm-security` `be14867` their four injection tables are built from this file and hold zero local
regex literals — measured on their published surface at `47905da`, with their vendored copy of
the lexicon confirmed byte-identical to `0.7.0`. So re-extraction was not available as a
mechanism: there is no upstream literal left to re-read. They re-measured the finding rather than
accepting it, rejected `[^>]{0,256}` because a bound is paddable and `[^>]{1,256}` because it
drops bare `<script>` and two corpus cases with it, chose `[^><]*`, and asked commons to carry
it. Recorded in a new `source_fidelity.owner_directed_changes` block — deliberately **not** in
`post_extraction_drift`, which would have said the source moved and commons followed, when the
source now reads commons.
Not decided by majority. The guard reached `[^><]` first and independently (`cff0437`), so all
three runtimes now agree, but a 3-of-3 count is not what moved this value and would not have
been sufficient. The justification is the same one that kept commons on `[^>]` through `0.7.0`:
this file tracks its declared source, and the declared source chose.
Accepted cost, stated plainly: content carrying a literal `<` between the tag name and the `>`
(`<script <x>`, `<script<div>`) stops matching. Measured across **all 90** conformance cases,
not only the four that cite these ids: zero lost a match, zero gained one. The dropped class is
real and unwitnessed by the corpus.
- `signatures/secret-egress.json` `0.2.0` → `0.3.0` — **the one-entry staleness disclosed in
`0.2.0` is closed by re-extraction, 18 → 19 patterns.** `OpenAI Legacy API Key`
(`\bsk-[A-Za-z0-9]{20}T3BlbkFJ[A-Za-z0-9]{20}\b`) enters at `order` 17, second to last; `JWT
(three-part token)` moves to 18 and stays last, which `ordering.last_entry_is_load_bearing`
requires.
Read out of the module text at a pinned public commit, never transcribed from the coord message
that reported it — the message contained the regex, and that is exactly the path
`evidence_limits` had ruled out. `refs/heads/main` on the public remote is `47905da`; `088e458`
carries the entry and was confirmed an ancestor with `git merge-base --is-ancestor` rather than
read off their log.
A side effect worth more than the entry: **all 19 positions were compared against the module** —
name, regex source, flags, order — with 0 divergences. Positions 0–16 came from a 2026-08-09
transcription whose module fidelity had stood recorded as llm-security's assertion rather than a
reproduced result. It is now reproduced, and that `evidence_limits` bullet is retired along with
the staleness one.
- `conformance/manifest.json` `0.3.1` → `0.3.2` — the `secret-egress` blocker prose said its note
would stand until the re-extraction landed. It landed, so item (2) (`openai-api-key-legacy` is a
real hole here) is marked closed, and the entry count moves 18 → 19. **The blocker itself does
not close**: 19 entries against the guard's 25 at different cut points is still a table
reconciliation nobody has performed, and one closed hole is not that reconciliation.
- `docs/lexicon-port-divergence.md` (informative) — the `[^>]` vs `[^><]` row gets the number
it never had for **this** side, and then gets closed. The guard disclosed that their `[^><]` is a
measured ReDoS fix (`cff0437`), not a preference, and asked commons to measure its own form
rather than take their word. Measured here in Node and Python: `<script\b[^>]*>` is **quadratic**
in scan position on input that denies it a `>` — ×4.0 per doubling, 6.7 s at 256 000 chars
against 0.41 ms for the guard's form.
Counted across the whole lexicon rather than assumed from the one row: 8 of 83 patterns carry
a bare `[^>]`, six of them bounded (`{1,256}`, measured linear) and **two unbounded**. The
second unbounded one, `hybrid-xss:iframe-src`, had not been named by any party — 16.9 s at
256 000 chars.
The finding was routed to the owning runtime, which is what `SECURITY.md` promises an outsider
would happen — the first time that route was walked from the inside. It came back as a decision
the same day, and the document now records the closure with the invariant intact: the
measurement travelled, the authority did not. Had `llm-security` declined, both rows would still
read `[^>]*` and this file would record a permanent divergence instead.
## [0.3.1] — 2026-08-11
**No pattern changed value. One shipped table is disclosed as stale, and the repository gains
the reporting route it did not have.** Nothing in `patterns`, `expected.json` or any id moved,
so a runtime that passes `0.3.0` passes `0.3.1` unchanged. Read the first entry anyway if you
vendor `signatures/secret-egress.json`: it now says, in the file, that it under-matches its own
source by one entry.
### Added
- `SECURITY.md` — the reporting route for a repository whose attack surface is **data**. It
answers the question an ordinary security policy does not have to: how to report that a
*detection-table entry is wrong*, and why a confirmed defect in extracted data is decided in
the runtime it was extracted from before it is changed here. Names what is in scope (a silent
false negative, a fixture that sanctions a miss, an unsafe normative clause, a secret in the
history, data gone stale against its source), what is a documented boundary rather than a
vulnerability, and the two classes that skip the routing — a real secret, and data authored
here rather than extracted. States plainly that fix latency is bounded by the owning runtime's
schedule and the consumer's pull, not by this repository's.
Written because `org-ops` recorded the file as missing against the org standard on
2026-08-11, and because four files here are detection data where a mistake is a detector that
looks like it works. `CONVENTIONS.md`, recorded in the same message, is not in this release.
- `README.md` — a short **Reporting a wrong entry** section pointing at it. Without it the
policy is a file nobody looking at the front page would know to open.
### Changed
- `signatures/secret-egress.json` `0.1.0` → `0.2.0` — **a staleness disclosure, not a data
change.** All 18 patterns are byte-identical to `0.1.0`; one entry is added to
`provenance.evidence_limits`. `llm-security` reports having taken the source `SECRET_PATTERNS`
from 18 to 19 by adding `OpenAI Legacy API Key`. That is recorded as their report and
explicitly **not** reproduced here — the commit carrying it is not on their public remote,
which was measured at `b1ba1fb` on 2026-08-11. What *was* measured here: none of the 18
patterns matches a legacy `sk-…T3BlbkFJ…` key shape. So a consumer vendoring this file
under-matches the seed hook by one entry, on a live credential shape, and now reads that in the
file rather than inferring it. It will be closed by re-extraction from a pinned public commit,
never by authoring the entry here from a message.
- `conformance/manifest.json` `0.3.0` → `0.3.1` — the `scope_planned.blockers` text for
`signatures/secret-egress.json` is corrected. Through `0.3.0` it ended by naming
`gcp-service-account-json` and `openai-api-key-legacy` together as ids "absent here". They are
two different kinds of fact, and one of them was misleading.
Measured 2026-08-11, by running this file's own 18 patterns in `order` over a service-account
document, against the guard at commit `e671edb`: a **complete** GCP service-account key file
*is* matched here, at order 11 (`Private Key PEM Block` — its `(?:RSA |EC |DSA |OPENSSH )?`
prefix group is optional, so the bare PKCS#8 header such a file carries matches). The same
document with `private_key` removed matches nothing here while the guard's marker pattern still
fires. That is a **cut-point** difference — the guard detects the document marker, this table
detects the key material — which is what the blocker is about, and not a missing entry.
`openai-api-key-legacy`, by contrast, is a real hole here today, and is now recorded as one.
The correction is folded into the existing blocker string rather than added as a sibling key:
`blockers` is a map from table path to text, and a second key under a table path would read as
a second table to anything iterating it.
- `docs/lexicon-port-divergence.md` (informative) — the residual `[^>]` vs `[^><]` row gains a
fuller witness set. `llm-security` measured the three forms as **totally ordered** by what they
match, each a strict superset of the next, and named two input classes the guard's narrower
class drops (`<script a="<" >x`, `<script<div>`) beyond the one commons had recorded.
Reproduced here independently, including the strict-superset property in both directions,
before being written down.
Their argument — that the narrower class buys an empty false-positive surface, since anything
reaching `[^>]`-and-not-`[^><]` already contains a literal `<script` tag — is recorded as
theirs and explicitly **not** what decided commons' form. Commons carries `[^>]` on provenance,
and would have carried `[^><]` had the source been the guard's. Also records that they asked to
hear the guard's reason for `[^><]` before commons shipped and commons shipped first, with why
that order was deliberate.
No data file touched; `v0.3.0` is unaffected.
## [0.3.0] — 2026-08-11
**A detection pattern changed value. That has not happened in this repository before, and it
is the reason this is a release.** `v0.2.0` changed what a runtime must *declare*; this one
changes what a conforming runtime *finds*. A consumer that vendors `0.3.0` and re-runs its
suite will see a finding on inputs that produced none under `0.2.0`. In 0.x that is a minor
bump by the rules; read the first entry below before upgrading, not the version number.
The lexicon `0.6.0` entry previously sitting under *Unreleased* is folded in here — it was
committed but never tagged, and `0.7.0` supersedes its central claim.
### Changed
- **`lexicon/injection-lexicon.json` (`0.5.1` → `0.7.0`) — `hybrid-xss:script-tag` converged
on `llm-security`'s current form.**
```
0.6.0 and earlier <script\b[^>]*>[\s\S]*?<\/script> closing tag REQUIRED
0.7.0 <script\b[^>]*> opening tag only
```
Byte-identical to `llm-security`'s `RegExp.prototype.source` at `b1ba1fb`
(`scanners/lib/injection-patterns.mjs:170`), verified by compiling both. They dropped the
closing-tag requirement in `90f576f` (2026-08-10) because it was a recall hole:
`<script>alert(1)` and `<script src=x.js>` both returned no finding.
**This is re-extraction, not revision, and the distinction is the whole justification.**
This repository's behaviour-preservation invariant forbids commons from *correcting* seed
data it believes is wrong — that rule stands and was not weakened. 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 its source
repository could not load as published.
**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 introduce a false
negative. The reverse change would not have been adoptable on the same reasoning.
Operator decision, 2026-08-11, on `llm-security`'s blocking request. Explicitly **not**
decided by the 2-of-3 majority across the three ports: a count of implementations is not a
mandate over detection data, and the provenance argument would hold with the guard on
either side.
Measured collateral: **none.** The full corpus was run under both patterns — 84/84
lexicon-scoped cases pass under `0.7.0`, and exactly one case's finding set differs between
the two forms (the new one below). The widening added no finding to any other case's input.
`source_fidelity` restructured to keep its numbers coordinate-bearing:
`patterns_byte_identical_to_source` keeps its key and its value (83) and gains the field it
was missing, `byte_identical_against_commit: b1ba1fb`. Against the original extraction
commit `b0de0ca` this file is now 82/83, recorded as `count_against_extraction_commit`.
`post_extraction_drift` — added in the folded-in `0.6.0` to record the then-open divergence
— is now marked `status: resolved in 0.7.0 by re-extraction` and carries the before/after
pattern text, so a consumer diffing against either commit has a coordinate for what it
finds.
- **`conformance/manifest.json` (`0.2.0` → `0.3.0`) — `case_id_derivation` extended with an
optional variant suffix.**
```
before case_id = <pattern_id, ':' → '__'>
after case_id = <pattern_id, ':' → '__'> [ '--' <variant-slug> ]
reverse truncate at first '--', then '__' → ':'
```
No existing case id moved, so this is additive. `--` was measured absent from all 83
ratified pattern ids and all 89 pre-existing case ids, which keeps the reverse transform
purely lexical — no lookup against the id list — the property the original one-to-one rule
was protecting.
The `one_case_per_pattern_id` key is **removed**, superseded by
`case_id_derivation.variant_suffix.supersedes`, which quotes its text. It was documentation
of the constraint, not data a consumer matches on, but it is called out here because a
removed key is normally a breaking change in this repository.
`omitted_payloads` gains `derivation_ground_withdrawn_in_0_3_0`: the guard's seventh
active-content payload was omitted on two grounds, and this change retires one of them. The
other stands, so the payload stays omitted — on one ground instead of two. **It was not
added back**; that is a separate decision, not a consequence of this one.
### Added
- **`conformance/hybrid-xss__script-tag--src-no-close/` (89 → 90 cases)** — input
`<script src=x.js>`, 17 bytes, expecting `hybrid-xss:script-tag`. The regression gate for
the change above, and the reason the corpus could not previously see it: the existing
`hybrid-xss__script-tag` input `<script>steal()</script>` matches the pattern under *both*
forms, so it passes either way. Reverting the pattern to its `0.6.0` form fails this case
and only this case — mutation-verified in both directions across all 90.
**The first case input authored in this repository** rather than reproduced verbatim from a
runtime's payload set, recorded in the new `authored_payloads` block rather than folded into
`payload_provenance`, whose value is precisely the claim that its inputs are verbatim
upstream. That claim stays exactly as strong as it was: 83 of 83. Both witnesses for this
axis were named by `llm-security` on 2026-08-10; this is the first of the two. Findings
measured through the guard's public API at `0dce50f` / `0.5.0`, with the existing case's
committed bytes and digest reproduced by the same harness in the same run as a control.
- **`schema/conformance-declaration.schema.json` (`0.1.0`)** — the shape a runtime publishes
alongside a conformance result, satisfying the §1.1 MUST that `v0.2.0` created and left
without a form. Requested by `llm-security` in those terms (runtime, commit measured,
implemented file paths) with the stated reason that two runtimes publishing free-form
declarations makes `83/83 + 6 not-applicable` unparseable by anyone but its author.
Carries the two arithmetic invariants §1.1 implies but cannot state unambiguously in prose:
the four verdict counts MUST sum to the total, and the total MUST equal the corpus case
count at the commit measured. Requires the enumeration arrays whenever their counts are
non-zero, which turns §1.1's "MUST still be enumerated" from prose into a schema failure.
Keeps `error` and `not_applicable` structurally distinct, per §1.1. Records
`declaration_source` — whether the declared set is derived from the runner's own constant or
hand-maintained beside it — because only the derived form makes the anti-narrowing fence
structural. **Deliberately not a gate:** nothing in this repository runs, and no validation
was asked for. Mutation-tested: the example validates, and five distinct defect classes are
rejected.
- **`spec/conformance-corpus.md` §1.1** — normative pointer to that schema, plus a SHOULD that
a runtime derive its declared set from the constant its runner uses to accept or reject a
`scope`, and record which it did.
### Fixed
- `docs/lexicon-port-divergence.md` — the `hybrid-xss:script-tag` row is closed on the
closing-tag axis, having reversed twice in three days (guard-diverges → commons-diverges →
converged). What remains open is the one-byte span difference: the guard excludes `<` from
its negated class and the other two do not, so `<script <x>` matches commons and
`llm-security` and not the guard. Measured by compiling all three forms, not reasoned from
the character classes; neither side has claimed it.
## [0.2.0] — 2026-08-11
The contract gained a normative MUST, which is why this is a release rather than a
metadata commit: **a runtime that conformed to `v0.1.0` does not conform to this one until
it declares the set of commons data files it implements.** In 0.x that is a minor bump by
the rules, but it is breaking in substance, and a consumer reading only the version number
should learn that here rather than from a failing suite.
Everything below this heading was previously listed as unreleased.
### Retracted
- **The claim that the Python guard's port cites `severity.mjs` for hybrid severity.** It is
false. It was carried in three places — `lexicon/injection-lexicon.json`
(`families[hybrid].severity_provenance.not_from`), `docs/lexicon-port-divergence.md`
(§ *Severity: the 8 hybrid patterns*), and the `[0.1.0]` entry below — and it was never
measured here. It restated an assertion received from `llm-security` (coord message
`20260809T201048Z`) as a commons finding.
Measured against the guard's own tree, which `llm-ingestion-pipeline-security` asked for
twice before this was checked: `severity.mjs` has **never** appeared in
`src/llm_ingestion_guard/injection_lexicon.json` at any point in that file's history
(`git log -S` returns no commits), and at `0bf0729` — the commit
`conformance/manifest.json` pins — the only tree-wide occurrence is `docs/PLAN.md:114`,
correctly attributing the *report* module to `output.mjs` + `severity.mjs`. The guard's
only source statement for the lexicon is the `note` at `injection_lexicon.json:3`, and it
names `injection-patterns.mjs`.
**No detection data moves.** `families[hybrid].severity` is still `high`, still sourced to
`injection-patterns.mjs:274-281`, re-verified at `b0de0ca`; `severity.mjs` still contains
zero occurrences of `CRITICAL_PATTERNS`, `HIGH_PATTERNS`, `MEDIUM_PATTERNS` and
`HYBRID_PATTERNS`, re-measured the same day. Only the sentence about the *other* repository
falls.
The retraction is marked in place rather than edited away, and it is worth naming why this
one survived review: the claim arrived bundled with a correct measurement of the same
question, from a repository that had done its half properly. The correct half carried the
incorrect half past the check — which is precisely the defect
`severity_provenance.not_from` was written to warn about, one level up.
### Added
- **`not-applicable`, a third conformance verdict** (`spec/conformance-corpus.md` §1.1). A
runtime now declares the set of commons data files it implements; a case whose `scope`
names a file outside that set is `not-applicable` rather than failed. §1 alone would have
reported an architectural difference as a defect — one seeding runtime has no
active-content table and never will, and 7 permanent failures say nothing a reader can use.
The verdict is fenced so it cannot become an exit: it attaches to a **table**, never to a
case (per-case opt-out is the silent skip §1 forbids), a declared set MUST NOT be narrowed
to convert failures into `not-applicable`, and such cases MUST still be enumerated rather
than dropped from the denominator. §8 now states the consequence: a pass count is
unreadable without the declared set beside it.
- **Six active-content conformance cases** — `active__markdown-image`, `active__markdown-link`,
`active__reference-link`, `active__autolink`, `active__raw-html`, `active__data-uri`. The
corpus goes 83 → 89, and `scope_covered` gains `signatures/active-content.json`.
Generated from measurement, not written: payload strings were extracted from the seed
runtime's `coverage.py` by AST — evaluating each `_scan_case` argument in that module's own
namespace rather than retyping detection data — then run through its public output gate.
The fixtures were then re-read from disk by a separate checker that re-computed every
digest, re-scanned the bytes and applied `exact-within-scope` independently of the
generator, because a generator agreeing with itself proves nothing: 6 cases, 0 failed
checks.
**These six prove less than the 83, and the manifest says so.** Their payloads come from
the only runtime implementing the table, so no second implementation's agreement could be
measured. They pin one runtime's behaviour as a contract a future implementer can be held
to — which is less than cross-runtime agreement and more than nothing.
- `signatures/active-content.json` **0.1.0 → 0.2.0** — a `pattern_id_space` block. Unlike the
lexicon's, nothing was constructed: `label_format` and the `constructs` keys were already
extracted verbatim, and their concatenation *is* what the seed runtime emits. The block
states an id space the file already had implicitly, and records that it is ratified by
**one** runtime rather than two.
### Changed
- `lexicon/injection-lexicon.json` **0.5.0 → 0.5.1** — provenance metadata only; no pattern,
id, alias, family or severity value changes.
- `conformance/manifest.json` **0.1.1 → 0.2.0** — the six cases, `scope_covered`,
`count_by_scope`, separate provenance and measurement blocks for the active-content half
(a different source structure at a different commit; one pin must not stand for two
measurements), and `scope_planned.blockers`.
- **`spec/conformance-corpus.md` §4 no longer claims scoping "asks a question both can
answer."** That held only while every case was scoped to the one table both runtimes
implement, and stopped being true the moment a case was scoped to a single-runtime table.
Scope narrows *what* is compared; it does not make every runtime a valid addressee. The
superseded sentence is named in place rather than edited away.
### Fixed
- **§4 now states that "belongs to a data file" means published there, never "shares its
prefix."** The distinction has a live witness: the seed runtime emits `active:oversize-input`,
a self-safety flag about its own scan cap, which carries the `active:` prefix but is no
construct in `signatures/active-content.json`. A prefix-matching runtime would pull it into
the comparison and fail a case over a finding the corpus makes no claim about. Recorded in
that file under `pattern_id_space.not_every_active_label` as well.
- **§6 now states the derivation's cost.** `case_id` derives from `pattern_id` alone, so a
single-finding scope holds at most one case per pattern id — there is nowhere in the name
for a second. The seed runtime's matrix drives *two* payloads at `active:markdown-image`;
measured, their in-scope finding sets are identical, and the second's only distinguishing
signal (`entropy:base64-blob`) falls outside every table this repository publishes. It was
dropped rather than given a discriminated id, which would have broken the reverse
transform, and it is named in `conformance/manifest.json` under `omitted_payloads` so that
6 built from 7 offered reads as a decision rather than a miscount.
### Measured, not shipped
- **The remaining four cases are blocked on two distinct unresolved questions**, now recorded
under `scope_planned.blockers` instead of the earlier blanket "no runtime has agreed to an
id space". That framing was wrong for both:
- **Carriers (3).** No adoptable id space, and a second problem underneath. The guard emits
two *stage-coupled* labels for one carrier — `sanitize:zero-width` on input,
`output:zero-width-present` on output, same split for bidi and unicode-tag — while
llm-security emits prose titles. A commons id must be invented stage-neutral, which no
other id space here required. And since `exact-within-scope` compares a finding *set*, an
id aliasing both labels makes the verdict depend on which entry point the runtime was
measured through — an entry-point dependence the lexicon cases do not have.
- **Secret egress (1).** Not an id-naming question at all. The two runtimes carry
**different tables**: 18 entries here against the guard's 25, cut at different
granularities (this file's single `GitHub Token` is four ids there, `Private Key PEM
Block` three, `Database connection string` four), with membership diverging both ways.
`aws-access-key-id` is the one clean 1:1 — which is why exactly one egress case was ever
offered. That number was a symptom, not modesty. A shared id space presupposes a table
reconciliation nobody has done.
## [0.1.0] — 2026-08-10
Initial extraction. Runtime-neutral detection data, the finding contract, and a conformance
corpus, extracted from the `llm-security` Node implementation and a Python guard **without
behaviour change** — that invariant is the release, not a caveat on it.
What the tag is worth resting on: seven of the eight JSON artefacts were rebuilt from the
commons file alone and diffed against their source implementation, three of them against the
source module at a pinned commit. The eighth says `verified: false` about itself. The corpus
holds 83 cases on which both seeding runtimes were measured agreeing exactly.
What it is not: `spec/decode-pipeline.md` does not exist, and the corpus constrains one of
the seven data files. Both absences are named in *Not included* rather than papered over.
### Added
- `conformance/` — **83 cases, one per injection-lexicon pattern**, plus `manifest.json`.
Each case is a directory holding `input.txt` (the exact bytes, no trailing newline) and
`expected.json` (the findings, named by commons pattern `id`).
Both seeding runtimes were measured producing the **same lexicon finding set on all 83**,
through their public entry points — `scanForInjection()` at `b0de0ca` and
`scan_output(source=OUTPUT)` at `0bf0729` — with labels mapped to commons ids through the
lexicon's own `aliases` block. Not through rebuilt regex tables: a table-level comparison
yields a number that describes neither runtime, which is the mistake the divergence
document had to retract.
**The 13 divergent patterns are in, unmarked, and that is the substantive result.** Their
divergence was measured on witness inputs — an attribute run padded past 256 characters,
an interior `<`, an unclosed `<script>` — and none of those shapes occurs in a corpus
payload. All 13 agree on their own case input. Nobody had to pick whose recall cost
becomes the contract, because the question was never reachable from these inputs. A
per-case caveat would have asserted a doubt the measurement disproves.
Inputs are the guard's `coverage.py` payloads, reproduced verbatim. One runtime authored
them; what makes them a cross-runtime corpus is the measurement through the other, and the
manifest records the asymmetry rather than averaging it away.
- `spec/conformance-corpus.md` — **normative.** How a case is read: `input.txt` is bytes and
is not to be trimmed or re-encoded, `expected.json` names findings by `pattern_id` only
(severity and OWASP anchor are looked up in the lexicon, never restated), and
`exact-within-scope` requires equality **restricted to the data files the case names**.
The field is `pattern_id`, not `id`, because this repository already publishes an unrelated
finding `id`: `schema/finding.schema.json` defines it as `DS-<scanner>-<counter>` from a
process-global counter — stable across neither runs nor processes. Two normative documents
using one word for a stable rule identity and a volatile per-emission sequence number would
have produced runtimes failing every case for reasons unrelated to detection. §3.1 states
the distinction and publishes the bridge a runtime actually needs: its own label maps to a
`pattern_id` through the lexicon's `aliases` object, and a runtime absent from that object
has no published way to be compared at all.
Scoping is what makes exactness safe — the two runtimes do not implement the same set of
tables, so a whole-report comparison would fail for reasons unrelated to the pattern under
test. Exactness is what makes the corpus worth running — a contains-only corpus is passed
by a runtime that flags everything. `observed_out_of_scope` is evidence, never expectation,
and an absent runtime key means **unmeasured**, not measured-empty.
The document also states the one place this repository's "every JSON file carries a
top-level `version`" convention does not apply: fixtures are versioned as a corpus, in
`conformance/manifest.json`. Stated rather than left to be discovered.
- `schema/finding.schema.json` — the finding contract plus the SARIF output profile.
Normative. Closed against the producer in 0.2.0; the JSONL profile is `not applicable`.
- `signatures/active-content.json` — the EchoLeak class (CVE-2025-32711): 17 patterns,
severities, opacity floors and pass order, from the Python guard.
- `lexicon/injection-lexicon.json` — 83 prompt-injection patterns in four families
(21 critical, 32 high, 22 medium, 8 hybrid).
- `codepoints/carriers.json` — six carrier tables: zero-width characters, the Unicode Tags
block, the Supplementary Private Use Areas, BIDI controls, the Cyrillic presence set and
the 28-entry fold-to-Latin homoglyph map.
- `signatures/secret-egress.json` — the 18 fixed credential and token shapes. Array order
is normative.
- `mapping/owasp-map.json` — four taxonomy maps (LLM, ASI, AST, MCP) over one shared
16-prefix key set.
- `calibration/calibration.json` — risk-score tier constants, verdict thresholds, risk-band
cutoffs, posture grade thresholds.
- `signatures/malware-signatures.json` — the known-bad-identity table for the `SIG` class:
seven signatures over four families (`webshell`, `reverse_shell`, `cryptominer`,
`hacktool`), reproduced verbatim from `knowledge/signatures.json` at `b0de0ca`, key order
included, with the source file's byte length and SHA-256 pinned in `provenance`.
The rules were the easy half. The file's substance is the line between the table and the
engine, drawn in `engine_behaviour_not_data`: **no rule carries a `flags` field**, because
the engine compiles every pattern with `i` unconditionally — so a consumer that compiles
these case-sensitively silently under-matches all seven. Each pattern is also run against
five decode variants, not just raw bytes; rules are filtered by an enabled-families policy;
a rule fires once per file; operator rules are merged at scan time; and the loader defaults
four missing fields rather than rejecting a rule. None of that travels with the data, and
all of it changes what a consumer sees.
Two honesty notes are in `evidence_limits` rather than in prose. Seven signatures are not
malware coverage — a clean `SIG` result is not "no malware", and the seed runtime's own
header calls the table "deliberately tight". And three of the seven match on **names**
(`xmrig`, `mimikatz`, `meterpreter`), so a document *discussing* those tools matches; the
seed runtime papers over this by excluding `knowledge/`, `tests/`, `docs/` and
`node_modules/` from the scan, which is engine behaviour and does not come with the table.
Verified: 7/7 rule objects field-identical to source including key order, no non-ASCII
bytes, and all seven compile in Node bare, `i` and `iu` (21/21) and in Python `re` (7/7).
Note the exact family spellings — `reverse_shell`, not `reverse-shell`, and `cryptominer`,
not `miner`; they are policy keys, and the working note that seeded this file had both wrong.
### Verification
Every file above except `calibration.json` was proven rather than transcribed: the data was
rebuilt **from the commons JSON alone** and diffed against the source implementation. Each
file records its own result and its own limits.
`calibration/calibration.json` carries `verified: false`. Its source arrived as a prose
summary rather than as code, so no differential check was possible, and the file names the
checks that were not run instead of attaching a caveat to a pass.
The corpus was verified the same way the data was — by a harness that does **not** share the
generator's knowledge. It reads only the case directories, re-runs both runtimes on the bytes
it finds there, and checks every field of every `expected.json`, digests included: **83
cases, 0 failures**. Two further checks, because a corpus that cannot fail is not evidence:
commons' family severity matches the severity the guard emits per finding, **83/83**; and
deleting the middle third of each input breaks **76 of 83** expectations. The 7 survivors are
the shortest payloads, where the mutation leaves the trigger intact — that is a weak
mutation, not a weak fixture, and it is recorded as such rather than rounded up.
- `docs/lexicon-port-divergence.md` — informative. A differential comparison of the two
ports of `injection-patterns.mjs` (this repository's and the Python guard's): 83/83
patterns correspond, 64 are byte-identical, 6 differ only by escaping and are proven
equivalent, and **13 behave differently**, with a witness input for each and misses on
both sides. The cause is two different ReDoS mitigations of one table. **No data file was
changed** — behaviour preservation holds and the finding is reported to the owning
repositories.
**Revised 2026-08-09 with one retraction.** The document claimed that *neither runtime
misses an attack*, on the grounds that every witness payload still produced a finding. It
does miss. That measurement ran the payloads against the **union of every pattern table
this repository holds**, and the rescuing hit came from `active-content.json` — the Python
guard's table. `llm-security` has no active-content table at all, so a union of commons
tables was read as a statement about each runtime separately. Re-measured through
`llm-security`'s own `scanForInjection()` at `b0de0ca`, all three witness payloads return
**`found: false`** — no finding whatsoever — while controls in the same run behave
normally. Three confirmed recall holes, which `llm-security` attributes to its v7.8.3 #24
ReDoS hardening and has logged as a v8.x task.
Also corrected: one of the 13 divergences does not reach report level, because the guard's
`hybrid-xss:javascript-uri` fires on the same witness at the same severity and anchor. The
report-level number is **12**. And the `hybrid` severity question that the document reported
rather than resolved is now closed — the reported hint was right, the citation behind it was
not.
**Revised again 2026-08-10.** The document said 13 was the number blocking `conformance/`,
since a fixture names labels. It blocks a fixture written over a **witness** input, and the
corpus contains none — all 13 agree on their own case input. The divergence itself stands
unresolved and unchanged; what was wrong was the claim about what it blocked.
Corrections are marked in place rather than edited away.
### Changed
- `schema/finding.schema.json` **0.1.0 → 0.2.0** — the schema is **closed**. It was seeded
from `sarif-formatter.mjs`, which *consumes* findings, so its property list could only ever
be a lower bound and `additionalProperties` had to stay open. The producer is now known —
`finding()` in `scanners/lib/output.mjs`, line 32 — and it returns an object literal with
**exactly ten keys and no spread**: `id`, `scanner`, `severity`, `title`, `description`,
`file`, `line`, `evidence`, `owasp`, `recommendation`. `additionalProperties` is `false`,
and the two keys the old schema never knew about (`id`, `evidence`) are added.
`id` gets its own definition: `DS-<prefix>-<counter>`, pattern `^DS-[A-Za-z]+-[0-9]{3,}$`.
The `{3,}` is deliberate — `padStart(3, '0')` is a minimum, so a run emitting more than 999
findings produces four digits. The id comes from a process-global counter, so it is stable
neither across runs nor across processes, and the definition says so before someone keys on it.
Nullability is now evidence rather than convention. Five keys are emitted as `null` rather
than omitted (`opts.x || null`), so a serialised finding always carries all ten. The
exception is the four assigned straight from `opts`: omit `description` and the key is
`undefined` and vanishes from the JSON. Verified by calling the real producer — ten keys in
memory, nine after serialisation.
**`owasp` is a string, not an array, and not one code.** Multiple codes are joined with
`, `. Measured across the seed runtime: 31 distinct values over 157 emission sites, 13 of
them multi-code, and **four mix taxonomies inside a single value** (`LLM06, ASI02` and
friends) with no discriminator saying which is which. That sharpens the edition problem
`mapping/owasp-map.json` already records, and it has a consequence nobody had written down:
`sarif-formatter.mjs` builds `tags: [f.owasp]`, so a finding anchored to two taxonomies
produces **one** SARIF tag with a comma in it. Nothing filtering on `LLM06` will match.
Reproduced end to end through the real `finding()` and `toSARIF()`, and logged as
`known_lossiness.owasp-tag-not-split` — consumer behaviour in `llm-security`, not data, so
it is reported rather than fixed here.
The **JSONL profile is `not applicable`, not `unspecified`** — the distinction is the point.
`unspecified` would claim a profile exists and merely has not been written down. No
finding-JSONL exists: findings are emitted only inside a single JSON envelope
(`output.mjs:140`). The one module that does write JSONL, `audit-trail.mjs`, writes *audit
events* under a different schema — where `owasp` is an **array**. Same field name, different
type, same repository. A consumer reading both through one code path will be wrong about one
of them, so the profile records the trap instead of leaving a TODO.
Verified: the schema is valid Draft 2020-12, every finding built by the real producer
validates against it, and four negative controls (extra property, missing `id`, malformed
`id`, unknown severity) are all rejected.
One new open question, unpatched by design: the producer's JSDoc lists **seventeen** scanner
prefixes including `IDE`, while all four maps in `mapping/owasp-map.json` are keyed on
**sixteen** without it. An `IDE` finding has no taxonomy mapping in any map. Adding the key
would be inventing detection data.
- `lexicon/injection-lexicon.json` **0.4.0 → 0.5.0** — the last null in the file is filled and
the id space is ratified. Two blockers close, no detection data moves.
`families[hybrid].severity` was `null`, deliberately, because the seed dump did not supply
it. It is **`high`** — and the interesting part is where that is written. The hybrid family
has no severity field anywhere; the engine assigns one by pushing `HYBRID_PATTERNS` matches
straight into the `high` bucket at `injection-patterns.mjs:274-281`. Both this repository
and the Python guard had first looked in `severity.mjs`, which contains no injection-family
severity at all. The guard's port holds the right value behind that wrong citation, so
`severity_provenance.not_from` records the miss explicitly: a wrong citation to a right
value is the harder defect to catch later.
> **Correction 2026-08-10 (see Unreleased):** the two sentences about *the guard's* citation
> are false and were never measured here. The guard's port cites `injection-patterns.mjs`,
> the right file. Everything above about `severity.mjs` containing no injection-family
> severity, and about where the value actually lives, stands and has been re-measured.
`pattern_id_space.not_yet_confirmed` is replaced by `ratification`. Both seeding runtimes
agreed on 2026-08-09 — `llm-security` ratified the 0.2.0 proposal as-is and treats an id
change as breaking on the same terms, and the guard confirmed the space its own port
supplied. `id` is now a cross-runtime contract, which is what `conformance/` was waiting
on to be able to name a finding.
`alias_evidence.llm_security` is sharpened rather than upgraded. All 83 alias strings were
confirmed equal to the module's `label` field, in order — so the alias is certainly the
pattern's name **in the table**. It is still not established that a finding carries it: the
producer is `output.mjs:finding()`, which emits `title` and has no `label` key at all.
Verified at table level, one level short of where it would matter. Match on `id`.
- `lexicon/injection-lexicon.json` **0.3.0 → 0.4.0** — verified against the source module
instead of against the dump it was transcribed from, and **two false provenance claims
retracted**. The source is now pinned: `b0de0ca` on the public remote, imported in Node
and compared entry by entry on `source`, `flags` and `label`.
The result is **83/83 byte-identical to source**, which is not what the file previously
claimed. It said two patterns had been rewritten from raw code points into `\uXXXX`
escapes; the module already writes them escaped, so nothing had been rewritten. The stored
pattern text was right the whole time — only the account of where it came from was wrong.
The dump had rendered the module's escapes as the characters they denote, and this
repository re-escaped them, arriving at the correct bytes by way of an incorrect story.
The same inversion ran the other way in `multi-lang:french`, which carried the class
spelled with a raw accented Latin `e` where the module writes it as the escape
`\u00e9` inside the same character class.
That was the one pattern of 83 not byte-identical to source,
and it is corrected. The two spellings are the same regular expression — verified in Node
bare and under `u`, and in Python `re`, over accented, unaccented, uppercase and
non-matching French input, with identical match offsets — so **no behaviour moved**. No
pattern in the file contains a non-ASCII byte now, matching the module, whose regex
literals are pure ASCII throughout.
Structurally: `normalisations` is now `[]` with a `normalisations_note`, matching the
convention already used in `signatures/secret-egress.json`, and a new `source_fidelity`
block carries the counts, the method, the verified class membership, and both retractions
in full. Retracted claims are recorded rather than deleted — the earlier equivalence
evidence (692 Node comparisons, 236 Python) remains true, it is simply no longer
load-bearing.
- `lexicon/injection-lexicon.json` **0.2.0 → 0.3.0** — the two aliases are no longer presented
as equally backed. `pattern_id_space.alias_evidence` now records each one separately:
`llm_ingestion_guard` is **verified** (the guard's coverage matrix asserts on that exact
string, so it is demonstrably what a guard finding carries), while `llm_security` is
**not** — it is the pattern table's own name, and the finding producer was never supplied,
with the known Node finding shape using `title` rather than `label`. Averaging the two into
one file-level claim would have repeated the defect this repository corrects per-table
elsewhere.
Also: `normalisations[].affects` now keys on `id` with the prose names kept beside it as
`affects_labels`. An internal cross-reference on label was a second identity space inside
the file the id was added to unify.
- `lexicon/injection-lexicon.json` **0.1.0 → 0.2.0** — every pattern gains a commons-owned
`id` and an `aliases` object naming what each seeding runtime calls it, plus a top-level
`pattern_id_space` block explaining the field. This exists because a `conformance/`
fixture has to name a finding and the two runtimes do not name the same pattern the same
way.
The id was **adopted verbatim from the guard's port**, which already carried both names,
rather than invented here. Matching was by `label` ↔ `desc` with em-dash normalised to
hyphen: 83/83, one-to-one, ids unique.
**No detection data moved.** Labels, patterns and flags are byte-identical in sequence,
no `flags` key was invented (78 before, 78 after), and stripping the three new fields
reproduces the previous committed file byte for byte — 23 566 bytes, identical. All 83
patterns still compile in Node bare and under `u` (166/166) and in Python `re` (83/83).
Neither `llm-security` nor the guard has ratified this id space yet; both were asked by
coord on 2026-08-09, and the file says so rather than implying agreement.
### Not included
- `spec/decode-pipeline.md` — needs the decode implementation. A normative spec inferred
from a data dump would be worse than an absent one.
- **Conformance for the other four tables.** The corpus covers the injection lexicon only.
The carrier, active-content and secret-egress tables have 11 convertible cases waiting in
the guard's matrix, and no ratified cross-runtime finding id between them — writing those
fixtures would mint a contract unilaterally, in the same stroke as the tag. Named in
`conformance/manifest.json` under `scope_planned`.
- The 29 non-convertible cases of the guard's 134 assert a runtime's **API surface** — that
a Python call raises `OKFPathError`, that a disposition engine composes two findings a
particular way. This repository does not own an API, so those belong to the guard's suite.
`spec/decode-pipeline.md` is named in the README as planned rather than linked, so nothing
in the repository points at a file that does not exist.

# llm-security-commons
## Kontekst
Runtime-nøytral kjerne for LLM/agent-sikkerhetsdeteksjon: detektor-data, normative
kontrakter og en conformance-korpus som **flere uavhengige runtimes** kan kjøre mot og få
**identisk verdikt** fra. Repoet er delt kjerne, ikke et produkt.
Kjente konsumenter (vendorer dette repoet, endrer det ikke):
- `llm-security` — Claude Code-plugin, Node/ESM-scannere.
- et Python-guard-repo — samme deteksjon i en annen runtime.
- en wiki/advisory-flate — konsumerer samme lexicon og mapping.
Å dele én identisk kjerne er hele poenget: to implementasjoner som gir ulikt verdikt på
samme input er per definisjon en bug i én av dem — ikke en meningsforskjell.
## Charter (HARD — bryter du denne, er endringen feil uansett hvor god den er)
**Ingen engine-kode. Ingenting her kjører.**
- ❌ Ingen `.mjs`, `.js`, `.ts`, `.py`, `.sh` som implementerer deteksjon, scanning,
normalisering, scoring eller I/O.
- ❌ Ingen `package.json`, `pyproject.toml`, lockfiler, dependencies, build-steg.
- ❌ Ingen import fra — eller kjennskap til — noe rammeverk, SDK eller runtime.
- ❌ Ingen nettverk, ingen modellkall, ingen tidsavhengighet, ingen tilfeldighet.
Alt her er **offline og deterministisk**.
- ✅ Kun: JSON-data, normative spesifikasjoner (Markdown), og fixtures
(`input` + `expected`).
Regelen finnes fordi kjernen skal være **fork-and-own**: en konsument på en runtime vi
ikke har tenkt på skal kunne vendore dette uten å arve et eneste teknologivalg.
Mønsteret er kopiert fra søsterrepoet `portfolio-optimiser-commons` (samme harde charter:
«nothing here may import/depend on a framework»).
## Stack
Ingen. Data + prosa. Filformater: JSON (data + schema), Markdown (spec), rå tekst
(conformance-input).
## Konvensjoner
### Data (JSON)
- **Hver JSON-fil har et topnivå `"version"`-felt** (semver-streng). Uten unntak.
- Hver JSON-fil har et topnivå `"$comment"` eller `"description"` som sier hva filen er
og hvor dataene kom fra (provenance).
- 2 mellomrom indentering, LF, avsluttende newline. UTF-8 uten BOM.
- Kodepunkter skrives som `"U+200B"`-strenger (lesbare i review), aldri som rå usynlige
tegn i JSON-kilden — bortsett fra i `conformance/*/input.txt`, som per definisjon
inneholder de faktiske tegnene.
- Nøkler er stabile identifikatorer. **Å endre en nøkkel er en breaking change** —
konsumenter matcher på dem.
### Spec (Markdown)
- Hver normativ spec har en `**Status: normative**`-markør øverst.
- RFC 2119-språk (MUST / MUST NOT / SHOULD / MAY) i store bokstaver, brukt bevisst.
- Informative dokumenter (`docs/`) har `**Status: informative**` og er aldri ground truth.
### Conformance
- Én katalog per case: `conformance/<case-id>/input.txt` + `conformance/<case-id>/expected.json`.
- `<case-id>` er stabil og beskrivende. **Å endre en case-id er en breaking change.**
- `expected.json` er ground truth. Er en runtime uenig med `expected.json`, er runtimen
feil — med mindre fixturen selv bevises feil, og da endres fixturen i eget commit med
begrunnelse.
### Sikkerhetskritiske tabeller — aldri fra hukommelse
`codepoints/carriers.json` (inkl. homoglyph-map), `signatures/secret-egress.json`,
`signatures/malware-signatures.json` og `signatures/active-content.json` er
**deteksjonsdata**. Et gjettet kodepunkt eller et regex med feil escaping er en stille
falsk negativ — en detektor som ser ut som den virker.
**Disse filene endres KUN fra verifisert kildedata** (dump fra konsument-repo,
Unicode-standarden, publisert leverandør-doc). Aldri fra egen hukommelse, aldri
«fylt ut for konsistens». Kan en oppføring ikke verifiseres: utelat den, eller marker
den eksplisitt uverifisert i `$comment`.
### Behaviour preservation (v0.1.0-invariant)
v0.1.0 er en **ekstraksjon**, ikke en revisjon. Data som er hentet ut av en konsument
skal gi **eksakt samme funn** når konsumenten senere leser dem herfra. Ser du noe du
mener er feil i seed-dataene: **ikke fiks det her**. Dokumentér avviket, send det til
konsumenten via `coord-send`, og la beslutningen tas der dataene er testet.
## Kommandoer
Repoet har ingen build og ingen test-runner (charter). Validering er ad hoc:
```bash
# Alle JSON-filer er velformet
find . -name '*.json' -not -path './.git/*' -print0 | xargs -0 -n1 python3 -m json.tool > /dev/null
# Hver JSON-fil har topnivå "version"
for f in $(find . -name '*.json' -not -path './.git/*' -not -path './conformance/*'); do
python3 -c "import json,sys; d=json.load(open('$f')); sys.exit(0 if 'version' in d else 1)" \
|| echo "MANGLER version: $f"
done
# Hver spec har normativ-markør
grep -L 'Status: normative' spec/*.md
# Charter-guard: ingen kjørbar kode har sneket seg inn
find . -type f \( -name '*.mjs' -o -name '*.js' -o -name '*.ts' -o -name '*.py' -o -name '*.sh' \) \
-not -path './.git/*' | grep . && echo 'CHARTER-BRUDD: kjørbar kode i commons'
```
## Arbeidsflyt
- **Versjonering:** semver på repo-nivå (tag `vX.Y.Z`). Hver JSON-fils `"version"` er
filens egen semver og bumpes når *den filen* endres — de er ikke låst til repo-taggen.
Nytt datafelt eller ny oppføring = minor. Endret/fjernet nøkkel, case-id eller
disposisjon = **major** (konsumenter bryter).
- **Versjonssync før commit:** endrer du en JSON-fil, bump dens `"version"`; endrer du
repoets kontrakt, bump repo-taggen + CHANGELOG.
- **Konsumenter varsles via `coord-send`**, ikke via antakelse. Et repo som vendorer denne
kjernen får ikke vite at kontrakten endret seg med mindre du sier det.
- **Aldri jobb i konsument-repoene fra en økt her.** Vendoring, oppgradering og
behaviour-verifisering skjer i konsumentens egen økt, med konsumentens tester.
- **Forgejo only** (`git.fromaitochitta.com`). Aldri GitHub, aldri `gh` CLI.
- `STATE.md` er LOCAL-ONLY (gitignored) — remote er en offentlig flate.
## Communication patterns
### Linking to local files
When pointing to local files in responses, always use markdown link syntax with a descriptive name:
- Use `[Human-friendly name](file:///absolute/path)` — never bare `file:///...` URLs or autolinks `<file://...>`.
- Always use absolute paths. Never `~/` or relative paths.
- For multiple files, render as a bullet list of named markdown links.
Why: bare `file://` URLs only render the first as clickable across multiple lines. Named markdown links make each entry independently clickable and look cleaner.
Example:
- [Brief](file:///Users/ktg/.../brief.html)
- [Research summary](file:///Users/ktg/.../research/summary.md)

# 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.
- The 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.
- 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**.

# llm-security-commons
Runtime-neutral core for LLM and agent security detection: detector data, normative contracts and a conformance corpus that several runtimes can share.
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](LICENSE)
Detection logic gets reimplemented every time it crosses a language boundary, and the
copies drift: the Node scanner flags a zero-width carrier the Python guard misses, and
nobody notices until an incident. This repository holds the part that should never have
been copied — the pattern tables, the code-point carriers, the calibration thresholds, the
finding contract, and a fixture corpus with expected verdicts — so that two independent
implementations can be held to the same answer on the same input.
It is for anyone building or maintaining a detector for prompt injection, secret egress,
unicode-carrier smuggling or active content in untrusted text, on any runtime.
**It holds no runnable code.** Data, specifications and fixtures only.
## Install
Nothing to install — this repository is **vendored into consumers**, not installed.
As a `git subtree` (recommended: history is preserved and upgrades are a single command):
```bash
git subtree add --prefix vendor/commons \
https://git.fromaitochitta.com/open/llm-security-commons.git v0.4.3 --squash
# later, to move to a newer tag
git subtree pull --prefix vendor/commons \
https://git.fromaitochitta.com/open/llm-security-commons.git <newer-tag> --squash
```
Or pin a tag and copy — `fork-and-own` is an explicitly supported path:
```bash
git clone --depth 1 --branch v0.4.3 \
https://git.fromaitochitta.com/open/llm-security-commons.git
```
Always vendor **a tag**, never `main`. The tag is what a conformance result can be
attributed to.
## Requirements
A JSON parser and the ability to read a text file. That is the entire dependency surface,
and keeping it that small is the point.
## What it does
| Path | Contents |
| --- | --- |
| [`lexicon/injection-lexicon.json`](lexicon/injection-lexicon.json) | Prompt-injection pattern lexicon: 83 patterns in four **severity** families (`critical`, `high`, `medium`, `hybrid`), each with a stable `id` and per-runtime aliases. The thematic class (`override:`, `evasion:`, `hitl-trap:`, …) is the id prefix, not the family. |
| [`codepoints/carriers.json`](codepoints/carriers.json) | Invisible and deceptive carriers: zero-width characters, BIDI controls, Unicode Tag block ranges, and the homoglyph map. |
| [`signatures/secret-egress.json`](signatures/secret-egress.json) | Credential and token shapes that must never leave a machine, in a portable regex dialect. |
| [`signatures/malware-signatures.json`](signatures/malware-signatures.json) | Known-bad **identity** for the malicious-code class (`SIG`): seven tight signatures over four families — PHP webshells, reverse shells, cryptominers, offensive tooling. Seven signatures are not malware coverage, and the file says so. |
| [`signatures/active-content.json`](signatures/active-content.json) | Active content that renders or fetches on its own — Markdown images, links, reference definitions and autolinks, `data:` URIs, active HTML. The EchoLeak class. |
| [`calibration/calibration.json`](calibration/calibration.json) | The numbers a detector must not invent: risk-score tier constants, verdict thresholds, risk-band cutoffs, posture grade thresholds. Transcribed from a prose summary, not differentially verified — the file says so itself. |
| [`mapping/owasp-map.json`](mapping/owasp-map.json) | Finding-id prefix → OWASP taxonomy entry (LLM / ASI / AST / MCP). |
| [`schema/finding.schema.json`](schema/finding.schema.json) | **Normative.** The finding contract — closed against its producer, ten properties — plus the SARIF output profile. The JSONL profile is recorded as `not applicable`, with the reason. |
| [`schema/conformance-declaration.schema.json`](schema/conformance-declaration.schema.json) | **Normative.** The shape a runtime publishes alongside a conformance result: which commons tables it implements, the commons commit it measured, and the four verdict counts. Required by the corpus spec §1.1; not validated by anything here, because nothing here runs. |
| [`spec/conformance-corpus.md`](spec/conformance-corpus.md) | **Normative.** How to read the corpus: what a case is, why `input.txt` is bytes rather than text, what `exact-within-scope` requires of a runtime, and how a runtime declares its table set so a case scoped outside it reads as `not-applicable` rather than as a failure. |
| [`conformance/`](conformance/) | 90 cases. One directory per case: `input.txt` in, `expected.json` out. Ground truth. 84 cover the injection lexicon — 83 one per pattern, both seeding runtimes measured producing the same verdict on all 83, plus one variant case gating a pattern form against its predecessor. Six cover active content and are measured against the one runtime that implements that table — `not-applicable` for the other, not failing. See [`conformance/manifest.json`](conformance/manifest.json). |
| `spec/decode-pipeline.md` | **Planned, still not shipped as of v0.4.3.** The decode order, in RFC 2119 language. Two runtimes that decode in different orders will disagree on identical input. Writing it needs the decode implementation, which is engine code and has not been supplied — and a normative spec guessed from a data dump would be worse than an absent one. |
| [`docs/extraction-plan.md`](docs/extraction-plan.md) | Informative: where each file was seeded from, and what v0.1.0 promised. |
| [`docs/lexicon-port-divergence.md`](docs/lexicon-port-divergence.md) | Informative: a measured disagreement between two ports of the injection lexicon — 13 patterns that behave differently, in both directions. Most of it is still open, and the two rows that closed in v0.4.0 closed because the runtime that owns the value decided, not because this document found them wrong. |
Every JSON file carries a top-level `version`. Every normative specification carries a
`Status: normative` marker. Rows marked **Planned** are named here because the layout is
part of the contract, but the file does not exist yet — they are not links, and nothing in
v0.4.3 depends on them.
Each data file records its own provenance and, in `verified`, how strongly it is backed.
`calibration/calibration.json` is currently the one file that says `false`: it was
transcribed from a prose summary rather than diffed against a running implementation.
### How a consumer proves it conforms
Run every `conformance/<case>/input.txt` through your detector and compare the finding ids
to `expected.json` — exactly, but only within the data files the case names in `scope`.
[`spec/conformance-corpus.md`](spec/conformance-corpus.md) is the normative reading;
the short version is that a runtime must raise every listed finding and no other finding
*from the same table*, and that what it does with tables outside the case's scope is not
compared.
Disagreement means your runtime is wrong, or the fixture is — and the fixture only changes
in its own commit, with the reason written down.
There is **no CI in this organisation** and nothing runs that comparison automatically. It
runs in each consumer's own test suite, against a pinned tag.
The corpus covers two tables, and they do not carry equal weight — treating them as one
number would misreport both:
- `lexicon/injection-lexicon.json` — 84 cases over 83 patterns. Both seeding runtimes
implement it and both ratified its id space. One pattern carries a second, variant case;
see `case_id_derivation.variant_suffix` in the manifest.
- `signatures/active-content.json` — 6 cases. One runtime implements it. For a runtime that
does not, these cases are **`not-applicable`**, a third verdict beside pass and fail: a
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.
Four cases remain unshipped, for the carrier and secret-egress tables, and neither is
blocked on effort. Carriers has no *ratified* id space: six labels exist to adopt verbatim
from one runtime, but adopting them would hand the other an id asserting a strip it does not
perform, and publishing a single alias would force that runtime's declared table set to widen
— turning three cases it cannot reach from `not-applicable` into failures. Put to both
runtimes as a decision request on 2026-08-11; unanswered. Secret egress is not an id question at all — the two
runtimes carry *different tables*, 19 entries against 25, cut at different granularities.
`conformance/manifest.json` records both blockers under `scope_planned.blockers`, measured,
so the gap is visible rather than inferred.
## Non-goals
- **Not a scanner.** There is no engine here, and there will not be one. If you are looking
for something to run, you want a consumer — `llm-security` for Claude Code.
- **Not a framework or a library.** No package manifest, no dependencies, no build.
- **Not a general-purpose Unicode or regex toolkit.** The tables cover what the detection
classes need, not the standard.
- **Not a vulnerability feed.** No CVEs, no advisories, nothing time-sensitive. Everything
here is offline and deterministic.
- **Not a policy engine.** `calibration.json` publishes the thresholds; deciding what to do
when one is crossed belongs to the consumer.
- **Not the place to fix a consumer's behaviour.** Data extracted from an implementation is
kept behaviour-identical on purpose. A disagreement is reported to that implementation
and decided there, where it is tested.
## Known limitations
- **Coverage is the union of what the seed implementations detected**, not of what exists.
A class absent from the tables above has not been shown to work anywhere.
- **The corpus is narrower than the data.** `conformance/` constrains two of the seven data
files. The other five are published, provenance-checked and unfixtured: a runtime can
pass every case and still read `calibration.json` wrongly. Passing the corpus is evidence
about the injection lexicon and about active content, and about nothing else.
- **A pass count is unreadable without the declared table set.** A runtime implementing one
table and a runtime implementing four can print the same number. `not-applicable` cases
must be reported, not dropped from the denominator — `76/83` and `76 passed, 6
not-applicable` describe different runtimes.
- **The six active-content cases prove less than the 83.** Their payloads come from the only
runtime that implements the table, so no second implementation's agreement could be
measured. They pin one runtime's behaviour as a contract a future implementer can be held
to; they are not cross-runtime agreement.
- **Regex portability is a real risk.** Pattern data is written for a common subset, but
engines differ (lookbehind, named groups, Unicode property escapes). A consumer whose
engine rejects a pattern must report it rather than silently skip it — a skipped pattern
is an invisible false negative.
- **Fixtures prove agreement, not correctness.** Two runtimes passing the same corpus agree
with each other and with the fixture author. A wrong `expected.json` makes both wrong
identically.
- **The homoglyph map is finite.** Confusable coverage is a long tail; absence from the map
is not evidence a character is safe.
## 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.
## Changelog
See [CHANGELOG.md](CHANGELOG.md).
## License
MIT — see [LICENSE](LICENSE). Fork-and-own is an intended use, not a tolerated one.

# 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:
- **hello@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. 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.
