The remote still said pharn-dev/pharn long after the rename, because GitHub's redirect keeps the old name resolving indefinitely — so the prescribed authority was downstream of the very fact it was meant to establish. Every check a careful agent would run against it (does the URL work? does git fetch succeed?) returns green on the stale name, and following the instruction would have rewritten four already-correct README badges to the stale slug. The request's stated symptom ("whichever slug is stale 404s") was false for the same reason, so reproducing the symptom before fixing would have found nothing wrong. Complements L6 by naming the case it does not reach — here the prescribed location IS structured and live and still wrong, so "read it from the structured place" is necessary and not sufficient when that place holds a mutable pointer. Sharpens L25 by identifying what is most dangerous to carry across: not a stale comment but a stale METHOD, which reproduces the error in every run that obeys it. Promoted through the gated /pharn-dev-memory-promote flow: check-provenance.mjs GREEN (unique id, target in enum, type/concepts well-shaped), human-approved at the accept/deny halt.

SKILLS_VERSION 2.7.12 -> 2.7.13. L2 check-regress: the gate-set mismatch check used `k in obj`, which walks the prototype chain, so a gate id colliding with an Object.prototype member read as PRESENT in a map that did not have it. The extra failing gate was treated as shared and the verdict came back no-regressions at exit 0, where a mismatch is contractually inconclusive/exit 2 — a silent pass inside the checker whose whole promise is that there is never one. Now Object.hasOwn (lessons-learned L15). L3 a UTF-8 BOM defeated every frontmatter anchor in the floor. FM_RE had been copy-pasted byte-identically into SIX checkers with nothing ranging over them, so a byte-valid file from a BOM-emitting editor RED'd in all six and fixing one would have left five broken with no test able to tell (L31). Adds the shared pharn/floor/frontmatter-core.mjs: one anchor, the BOM stripped at READ beside the existing CRLF fold (L25), and a consumer-set pin asserting no checker re-declares the anchor, each imports the core, and each actually calls stripBom. Exactly one leading U+FEFF at offset 0 is stripped — a frontmatter-less file still REDs, so this removes a false red without creating a false green. L5 check-spec --hash and --spec-id exited 1 silently on an unreadable file, handing a caller an exit code and nothing to surface. --state already reported, and its comment documented that divergence as deliberate; all three modes are now uniform and that comment was re-derived rather than left stale (L25). Exit codes unchanged — this adds a diagnostic, it does not strengthen a gate. L6 lessons-index-core: a bare catch mapped EVERY read failure to benign NO_CANON, so EACCES/EISDIR on a canon that exists and holds lessons made /pharn-plan declare applied_lessons: none. Now membership over e.code — only ENOENT/ENOTDIR are benign, everything else rethrows. The deliberate product-vs-dev divergence on an ABSENT canon is preserved and pinned. L7 check-structural certified fully suppressed output: the per-finding kinds all iterate the findings array and are vacuously true over [], so an eval asserting only those passed against a skill that emitted nothing. Guarded, with the legitimate empty case still expressible as finding_count == 0. The per-finding set is derived from KIND_ENUM by subtraction so a new kind cannot be forgotten. L9 scan-code-injection missed .concat(): the taint set enumerated the operator spellings and omitted the method one. Added, header re-derived, and Python f-strings NAMED as out of scope rather than silently unhandled.

L4 the dev check-lessons-index reported ENUM_ERROR with file: OUT_PATH, the GENERATED index, when the thing to fix is canon: the generator refuses exactly the invalid canon the checker refused, so naming the output prescribes a regenerate that cannot succeed. `file` is the enum-gated field a consumer trusts to name the file to open. The product twin was corrected first and pinned it by test; this is the backport, plus assertions that MISSING/DRIFT still correctly name the output (the fix is scoped to one branch, and saying so requires asserting the others did not move). L8 the cross-surface pin compared ONE function body (cleanScalar) and read as discharged while four siblings could diverge freely. Per L29 the deliverable is the ENUMERATION, so both sets are now materialised and a completeness rule asserts they COVER every function in both cores — a function added later must be classified as shared or divergent and cannot sit silently unpinned. Two corrections came out of running it, neither of which the fix request anticipated: - The pin compares CODE, not raw source. The cores are allowed to explain themselves differently, and one difference is load-bearing: a user's install ships pharn/floor/ WITHOUT .dev/, so the product copy deliberately avoids citing dev-only artifacts a reader could never open. A byte pin would fight a divergence that is correct. Only whole-line comments are stripped, so a `//` inside a string on a code line cannot be mangled into a false match. - renderIndex is DIVERGENT, not shared. The request listed it as shared; the live cores say otherwise — the product header describes a disposable cache and keeps the benign reading of the absent-tag marker, because a user's memory-bank may hold hand-written entries. Reclassified from reading the code, not from the request. L11 package.json's version was a third identity to keep in sync with SKILLS_VERSION and the README badge, and nothing stopped a well-meaning bump from passing every gate. It is now deliberately inert (0.0.0) and says so in the file. Option (b) — pinning it to SKILLS_VERSION — was rejected: it would create the very third identity this removes. The sweep found the claim asserted in three more live places, all now re-derived (L1/L25): CHANGELOG's preamble, README's status note, and a check-version-badge.mjs header comment. Note the request described "a 1.0.0 git tag" as one of the three identities — no tag exists, local or remote (verified), so both docs' "the 1.0.0 tag" always meant the package.json field. L10 .pharn/ mixes two load-bearing entries (writes-scope.json, the lessons-index cache) with per-command scratch in one flat namespace, with no stated convention. Documented in CLAUDE.md and CONTRIBUTING: what is load-bearing, that scratch belongs under .pharn//, and that clearing scratch means removing those subdirectories rather than rm -rf .pharn/ (which discards the cache). ADVISORY — no checker enforces it and none is added. Existing scratch is deliberately NOT swept: .pharn/fixes/ is in active use. L13 records that the product /pharn-eval twin is intentionally deferred, in the style its two peers use (product-capability-catalog, /pharn-verify's verifier runner). The absence was consistent with the P7 posture but stated nowhere, so a reader could not tell a deliberate deferral from an oversight. The record lives at .dev/features/product-eval/, matching the product-* slug of its peers. It does NOT go in .dev/features/pharn-eval/, which is already the historical build record for increment 3c — the plan that built /pharn-dev-eval itself, back when that command was still to be named /pharn-eval. An earlier draft of this commit overwrote that record; it is restored byte-identical here.

Delivered as a reviewable copy plus a diff. The defect: JSON.parse("null") returns null without throwing, so the IIFE's catch never fires and payload.tool_name dereferences into an uncaught TypeError. That exits 1, which Claude Code treats as NON-BLOCKING — so the write PROCEEDS. A crash in a write-guard is a fail-OPEN bypass, which is the one failure mode this file may not have. Reproduced live: `echo 'null' | node .claude/hooks/enforce-writes-scope.cjs` throws with rc=1. Array and scalar payloads happen not to crash today (they reach property access on a non-object without throwing), but they are the same class and the guard covers all of them. No exploitable write is claimed: the payload comes from Claude Code, not an attacker, so there is no known path to reach it with null. The defect is a doctrine violation — the repo's own threat model says a write-guard's crash is a bypass — not a live vulnerability. The fix mirrors the guard protect-trusted-paths.cjs ALREADY carries, comment included. The two hooks run on the same PreToolUse payload and must not disagree about what a payload IS; that one had the guard and this one never got it, which is the copy-pair shape L31 names. Delivered as .claude/hooks/test.cjs — byte-identical to the live hook except the fix, so `diff .claude/hooks/enforce-writes-scope.cjs .claude/hooks/test.cjs` shows exactly one hunk. It is inert: nothing wires it (hooks are wired by explicit path in settings.json), and it does not match npm test's *.test.cjs glob. Delete it once the fix is applied by hand. Verified: the copy returns rc=0 on null/[]/"x"/42 where the live hook throws on null, and still denies a real out-of-scope write with rc=2. eslint and prettier clean; npm run check exit 0.

That +// trained the exact bypass this guard exists to prevent, undirected. The branch below states the structural +// fact and offers only reachable options; it changes NO verdict and allows NO new path. +// +// toRel() returns null for THREE situations, and the wording "not INSIDE the repo root" is chosen to stay +// true for all of them: the target resolves outside the root, it is a `../` traversal, or it resolves to the +// root ITSELF (path.relative(ROOT, ROOT) === "" — reachable with file_path "."). "Outside the repo root" +// would be false for the third. Do not narrow it. +// +// Both bodies must stay PURE STRING COMPOSITION over values already in hand. deny() builds the message +// BEFORE it exits 2, and a throw here would exit non-2 — which PreToolUse treats as a non-blocking error, +// i.e. the denial would fail OPEN.

Both were true and both were beside the point: .dev/floor/capability-catalog-core.mjs ENUMERATES .claude/hooks/*.cjs into the README's generated CURRENT-STATE block. The copy therefore turned docs:check RED, and regenerating would have had the README assert "Hook scripts — 4", naming a proposal as a live hook. That is a false claim in a generated inventory — the exact drift class this batch exists to remove, and it would have shipped in the same PR that documents the docs:generate obligation. The proposal now lives beside its own increment record as .dev/features/hook-null-payload/enforce-writes-scope.proposed.cjs, still byte-identical to the live hook except the fix, so a diff against the real file shows exactly one hunk. The reasoning is recorded in that increment's PLAN so the next person does not reach for the same obvious-but-wrong location. npm run check exit 0; README byte-unchanged.
