The lexicon was seeded from a transcribed dump. With the source module now
readable read-only at b0de0ca on the public remote, it was imported in Node
and compared entry by entry - RegExp source, flags, label, family, array
order. That check contradicted the file twice, in mirror-image ways.
The file claimed it had rewritten raw code points into \uXXXX escapes in
homoglyph:cyrillic-latin-mix and unicode:zero-width-in-word, and carried
byte_identical_to_source: false for both. The module already writes them
escaped. Nothing was ever rewritten. The stored pattern text was correct
throughout - only the account of its origin was wrong, because the dump had
rendered the module's escapes as the characters they denote and this
repository escaped them back.
The same inversion ran the other way in multi-lang:french, which stored a raw
accented Latin e where the module writes the é escape. That was the one
pattern of 83 not byte-identical to source, and it is corrected here, making
it 83/83. Both spellings are the same regular expression: compiled in Node
bare and under u, and in Python re, over accented, unaccented, uppercase and
non-matching French input, with identical match offsets. No behaviour moved.
Exactly one pattern entry differs from HEAD, and no pattern in the file
contains a non-ASCII byte any more - which matches the module, whose regex
literals are ASCII throughout. A third claim fell with them: the translation
note asserting that the leetspeak and multi-language patterns embed accented
Latin directly was wrong in both halves.
normalisations is now [] with a normalisations_note, the convention already
in signatures/secret-egress.json. A new source_fidelity block carries the
counts, the method, the verified class membership, and both retractions in
full - retracted, not deleted. The equivalence evidence behind the withdrawn
claim (692 Node comparisons, 236 Python) is still a true statement about raw
versus escaped; it is just no longer load-bearing.
Provenance upgraded accordingly: source_commit pinned, and the caveat saying
these checks only proved agreement with a dump is gone, because they no
longer do.

Advisor review found six gaps the session's own checks did not cover. The one
that mattered was outward-facing: the divergence report told the guard repo
that two sub-agent bounds were undocumented. That was wrong. lexicon.py's
module docstring documents them explicitly under "Bounded token gaps", and
git log -S dates {0,12} to the original port commit f397cd9 and [^><] to the
ReDoS fix cff0437. Every divergence on the guard's side is documented and
traceable. The claim rested on two sed slices of one file; an absence claim
needs a search over the whole repository. Corrected here and by coord.
lexicon/injection-lexicon.json 0.2.0 -> 0.3.0:
- pattern_id_space.alias_evidence records the two aliases separately instead
of averaging them. llm_ingestion_guard is verified — coverage.py asserts on
that exact string, so it is demonstrably what a guard finding carries.
llm_security is not: it is the pattern table's name, the finding producer
was never supplied, and the known Node finding shape uses title, not label.
- 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 exists to unify.
Detection data unmoved again: labels, patterns, flags and the ids and aliases
added in 7b70f5b are all byte-identical in sequence; 166/166 Node compiles.
Also: the README lexicon row described thematic families the file does not
have (they are severity families; the theme is the id prefix), and the
conformance convertibility table gained its missing second condition — a case
is buildable only if the label it asserts maps to data this repository
publishes. Eleven cases fail that test (entropy, decoded, the sanitize rows,
the OKF scans), so the buildable set is ~94, not 105.

A conformance fixture has to name a finding. The two runtimes that seed this
repository do not name the same pattern the same way -- llm-security says
"override: ignore previous instructions", the guard says
"override:ignore-previous" -- so until now no expected.json could be written
at all, including for the 64 patterns whose regex is byte-identical in both.
Each pattern now carries `id` plus an `aliases` object naming what each
seeding runtime calls it, and a top-level pattern_id_space block explains the
field, its provenance and its stability contract.
The id is adopted verbatim from the guard's port rather than invented here:
that port already carries both names, so the mapping is read from source data.
Matched by label <-> desc with em-dash normalised to hyphen, 83/83 one-to-one,
83 unique ids.
No detection data moved, and that is proven rather than asserted: labels,
patterns and flags are byte-identical in sequence, no flags key was invented
(78 before, 78 after), and stripping id + aliases + pattern_id_space
reproduces the previous committed file byte for byte -- 23566 bytes. All 83
patterns still compile in Node bare and under u (166/166) and in Python re
(83/83).
Neither consumer has ratified this id space; both were asked by coord today,
and the file records it as a proposal rather than implying agreement.

The four prompt-injection pattern families — 21 critical, 32 high, 22 medium,
8 hybrid — with per-pattern label, ECMAScript source and declared flags.
Data only. The dump names checkCognitiveLoadTrap and scanForInjection's
variant building (normalise → fold → rot13 → unicode-tag escalation) as
ENGINE logic that never moves here; they are absent by intent, not omission.
Proven, not transcribed: all four arrays were rebuilt from the commons JSON
alone and diffed against the imported dump module — 83/83 identical on label,
source and flags, 81 of them byte-identical. All 83 compile in Node bare, Node
under `u`, and Python `re`.
Two deliberate deviations from byte-identity, declared in the file: the
zero-width and Cyrillic character classes carried raw code points, four of
them invisible. Escaped to \uXXXX (the convention forbids raw invisible code
points outside conformance inputs — an unreviewable class is where a silent
false negative hides) and proven equivalent by differential match-set
comparison over 208 adversarial inputs, 832 comparisons, 0 differences.
Class membership was counted from the dump bytes: the zero-width class holds
4 code points and does NOT include U+00AD.
HYBRID_PATTERNS' severity was not supplied and is left null rather than
inferred from its siblings. Verification log in docs/extraction-plan.md.
