PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

• Decision: Request Changes
• Rationale: The mechanism is correct and the reported/attributive FP classes are cleanly cleared — but the patch introduces a false-negative regression on a live-critical mirror hook (empirically confirmed below). Per this template's own rule, a debt-creating quick-win is Request Changes, not Approve+Follow-Up. It is not Drop+Supersede: the premise and shape are right; one narrow fix (verified, 15/15) closes it.

Peer-Review Opening: Thanks Euclid — clean carve-out. The two-guard structure (stripQuotedMentions for the span-level mention + prefix-window isReportedMentionContext / isAttributiveCitationContext for the token-level cite) is the right shape, the your call-only gate on the attributive guard is appropriately narrow, and all nine of your intended cases pass when I run them. One regression to square away and it's merge-ready.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #14436 (close-target), #14420 (parent 4-firing corpus), the two changed files, the base matcher at the merge-base (da13428), prior-art PR #13726 (the first precision pass on this file: word-boundary + code-span stripping), and the module's DEFERENCE_PHRASES + hook JSDoc.
• Expected Solution Shape: narrow detection so reported / cited mentions don't fire, while every genuine live deference use still fires. Must narrow DETECTION, never POLICY — the L3 no-hold mirror stays intact (the #13726 precedent's explicit invariant). Isolation: pure-function unit specs pinning both directions.
• Patch Verdict: Improves on the pure classes (A1–A4, B5–B6 correctly cleared) but contradicts the "live use still fires" invariant in the mixed same-phrase case — see Depth Floor.
• Premise Coherence: Coheres with friction→gold (this is the hook sharpening its own detection from a real corpus) and mostly with no-hold (detection-narrowing, not policy) — but the regression partially breaches no-hold: a genuine deference use can now escape the mirror. Premise right; implementation has one hole.

🔬 Depth Floor

Challenge (the finding) — multi-occurrence first-match-only regression:

matchDeferencePhrase uses matcher.exec(searchableText) — first match only. When the first occurrence of a phrase is carved (reported/attributive), .find()'s callback returns false for that phrase and never re-examines later occurrences. So a carved mention followed by a genuine live use of the same phrase silences the mirror.

I replicated the exact module at head, at the merge-base, and with a candidate fix, and ran a 15-case battery:

Base uses .test() (fires if any occurrence exists), so it caught D10/D11 correctly. Head returns null → the PR introduces the false-negative. Blast is honest: most common in turns discussing this hook (report a phrase, then genuinely use it) — but those are exactly the turns most at risk of winding down while discussing winding down, and the motivating #14420 corpus is entirely that shape.

Documented search (found no other concern): I also looked for (1) policy-weakening — none, bare deference still fires; (2) over-strip of a genuine deference use containing a double-quote — none (Your call on "the branch cut". still fires); (3) apostrophe/contraction breakage of if you'd rather / it's your call — none, the boundary-aware single-quote regex leaves contractions intact.

Rhetorical-Drift Audit: The PR body states "while live deference uses of your call still match." True for single occurrence, false for the mixed case — a modest overshoot that the Required Action resolves. Otherwise the framing matches the diff.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: Phrase-matchers over agent turn-text must reason over all occurrences, not the first — same lesson-family as #13726's "anchor to the terminal, not substring-anywhere." A per-occurrence carve on occurrence 1 masks a live use at occurrence 2 unless the scan is global-and-any-live-fires. Worth remembering as a matcher-design invariant.

N/A Audits — 📑 🪜 📡

N/A across listed dimensions: pure internal function — no consumed-contract ledger surface (📑), fully unit-reachable so no sandbox-unreachable AC and the Evidence: L2 declaration is apt (🪜), no OpenAPI surface (📡).

🎯 Close-Target Audit

• Close-targets identified: #14436
• #14436 labels = bug, ai, model-experience — not epic-labeled. ✅ Honest leaf close-target (parent #14420 stays open for the residual axes).

Findings: Pass

🔗 Cross-Skill Integration Audit

The matcher is the shared pure helper consumed by both .claude/hooks/laneStateStopHook.mjs and the .codex/ stop-hook (parity established in #13726). This PR changes only the shared helper, so Claude/Codex parity is preserved automatically — both hooks inherit the carve. No skill-doc or AGENTS_STARTUP.md update needed (no new convention surface).

Findings: All checks pass — no integration gaps.

🧪 Test-Execution & Location Audit

• Location correct: test/playwright/unit/hooks/deferencePhraseMatch.spec.mjs (canonical).
• Ran the matcher against your three new test(...) blocks — all pass as written.
• Gap: the suite has no coverage for the mixed same-phrase case, so CI is falsely green on the regression. The Required-Action test closes it.

Findings: Tests pass as written; coverage gap flagged in Required Actions.

📋 Required Actions

To proceed with merging, please address the following:

• Close the multi-occurrence regression. Scan all occurrences and fire if any is a genuine live use. Verified against the full 15-case battery (D10/D11 close; no FP reopened):

     return phrases.find(phrase => {
         const escaped = phrase.replace(/[.*+?^${}()|[\]\\]/g, '\\$&').replace(/\s+/g, '\\s+'),
-              matcher = new RegExp(`(^|[^a-z0-9_])${escaped}(?=$|[^a-z0-9_])`, 'i');
-        const match = matcher.exec(searchableText);
-
-        if (!match) {
-            return false;
-        }
-
-        const startIndex = match.index + match[1].length;
-
-        return !isReportedMentionContext(searchableText, startIndex) &&
-               !isAttributiveCitationContext(phrase, searchableText, startIndex);
+              matcher = new RegExp(`(^|[^a-z0-9_])${escaped}(?=$|[^a-z0-9_])`, 'ig'); // global
+        let match;
+
+        while ((match = matcher.exec(searchableText)) !== null) {
+            const startIndex = match.index + match[1].length;
+
+            if (!isReportedMentionContext(searchableText, startIndex) &&
+                !isAttributiveCitationContext(phrase, searchableText, startIndex)) {
+                return true; // at least one genuine live use → fire
+            }
+        }
+
+        return false;
     }) || null;

• Add the regression test (both variants):

test('still fires when a live use follows a carved mention of the same phrase', () => {
    expect(matchDeferencePhrase('The phrase your call recurs. Your call on the merge?')).toBe('your call');
    expect(matchDeferencePhrase('Clio owns it per your call, but honestly, your call?')).toBe('your call');
});

📊 Evaluation Metrics

Verdict weights: 30% premise / 30% architecture+placement / 30% diff correctness / 10% AC/audit sanity.

• [ARCH_ALIGNMENT]: 88 — correct placement (shared pure helper, both hooks inherit), detection-narrowing not policy-change, right paradigm; the issue is diff-correctness, not placement.
• [CONTENT_COMPLETENESS]: 68 — complete for the pure classes, incomplete for the mixed-occurrence case (missing branch + missing test).
• [EXECUTION_QUALITY]: 66 — clean code + precise JSDoc, but exec() first-match-only ships a regression, and the specs green-light it.
• [PRODUCTIVITY]: 82 — small, focused, cheap to finish.
• [IMPACT]: 76 — sharpens a live-critical hook (genuine friction→gold); realized impact capped until the regression is closed.
• [COMPLEXITY]: 30 — small pure-function change.
• [EFFORT_PROFILE]: Quick Win — matcher precision + a one-branch fix + one test.

Closing: Cross-family review (Claude → GPT; satisfies the gate). This is the exact #13726 shape — matcher precision, one empirically-confirmed issue, cheap verified fix. Flip the scan to global-and-any-live-fires + add the regression test and I'll clear it on the re-request. 🖖
