Resolves #15216

Mid-TURN operator messages become visible to the stop-hook's human-filtered walk — with envelope provenance, not payload text, as the sender/kind identity (hardened per Emmy's review falsifier). Claude Code delivers "sent while you were working" messages as type: 'attachment' records; the corpus-validated human predicate is attachment.type: 'queued_command' + commandMode: 'prompt' + a non-empty STRING source_uuid + origin.kind === 'human' (operator/wake deliveries) versus commandMode: 'task-notification' with neither field (background-task events). The walk classifies that envelope BEFORE reading any prose, validating SHAPE rather than field truthiness (hardened per Emmy's cycle-2 falsifiers: an object-valued or whitespace source_uuid, a non-'human' origin.kind, or a missing origin all fail the predicate): only the validated operator/wake shape yields a candidate (which then flows through the unchanged single classification authority, isOperatorDialogueText); a prompt-bearing record missing ANY predicate leg — task notifications, unknown modes, malformed/spoof-shaped envelopes — is a walk-stopping autonomous boundary that can never leak past to older operator prose; prompt-less attachment kinds are skipped. Newest-candidate ordering holds across record kinds (spec-pinned), isMeta is honored for every record kind, and the <task-notification synthetic pattern remains in the shared decision module strictly as defense-in-depth for the user-record path — documented as such, never the discriminator.

Evidence: L2 (spawned real hook over fixtures mirroring the real queued_command envelopes; 145 specs green across the three hook suites at the current head — laneStateStopHook + stopHookDecision + the untouched Codex sibling — incl. the untagged-prose falsifier chain, the four spoof-shape predicate falsifiers, the malformed-present-prompt falsifier, and the three spawned walk-stop BLOCK chains) → L3 (live-session classification post harness-restart). Residual: post-merge live audit observation [#15216].

Corpus note (AC-5, envelope-grounded)

Census across ALL local transcripts (both project dirs, every session — reviewer-reproduced independently at cycle-4; the JSDoc/walk-comment/fixture-comment surfaces share the verified 360/360 current-delivery and 118/118 task-notification split while identifying pre-July envelopes as format history; the #15216 Contract Ledger records the measured 188 historical records plus the three-way prompt-value boundary): 360/360 current-format prompt deliveries carry commandMode: 'prompt' + a non-empty STRING source_uuid + origin.kind: 'human'; 118/118 task notifications carry commandMode: 'task-notification' and neither field; 188 pre-July prompt records lack origin/timestamp entirely — the envelope gained those fields in a late-June harness update, so they are format history outside the live contract (the earlier 41/41 and the reviewer's 47/47 were both narrower in-window samples of the same split). No skill payloads, hook feedback, or system reminders ride attachment.prompt. The consumed-format Contract Ledger (five record-shape rows → candidate/boundary/skip) is backfilled on #15216.

Deltas from ticket

• Reviewer-hardened discriminator (Emmy's catch, the review bar working): my first head recognized task-notifications by the <task-notification prose prefix while attesting the result as mechanically human-filtered — a structurally synthetic record with untagged prose ("background task complete") would have false-ALLOWed. The envelope fields the ticket's corpus-check arm anticipated are the real identity; the fix classifies them first, and the untagged falsifier is now a spawned-hook e2e case.
• Boundary semantics for synthetic/unknown prompt-bearing records (stricter than skip): a newer task-notification or unknown-mode record stops the walk entirely, so older operator prose cannot be rescued past it — fail-closed at the authority boundary.
• The ticket's "gate should be presence of attachment.prompt" arm resolved to presence + envelope shape; presence alone was proven insufficient twice (first by my census's tagged payloads, then by Emmy's untagged falsifier).

Test Evidence

• Hook suites (current head): laneStateStopHook + stopHookDecision + codexLaneStateStopHook — 145 passed (envelope-real fixtures; the untagged task-notification + unknown-mode falsifiers as walk-boundary specs AND spawned e2e BLOCK chains — the unknown mode ABOVE older operator prose with every other envelope leg valid, isolating the mode check; four spoof-shape predicate falsifiers (object/whitespace source_uuid, origin.kind:'task', missing origin) as pure walk-stops; the malformed PRESENT non-string prompt as a pure walk-stop AND a spawned BLOCK above older operator prose, with absent/blank prompt pinned as the skip boundary; the operator-envelope [WAKE]-prose case pinned as candidate-then-rejected; cross-kind newest-candidate ordering pinned).
• Codex sibling: green unchanged (no attestation → fail-closed semantics untouched).
• Directly touched surfaces: ai/scripts/lifecycle/stopHookDecision.mjs: stopHookDecision.spec.mjs | .claude/hooks/laneStateStopHook.mjs: laneStateStopHook.spec.mjs.

Post-Merge Validation

• After harness restarts pick up the merged hook: observe a live mid-turn operator message classifying midChainOperator=true → ALLOW in lane-state-stop-hook.log.
• Confirm background-task notification deliveries never produce an ALLOW (boundary semantics: the chain stays autonomous).

Commits

• 444a1716b3 — walk extension + synthetic-pattern addition + 8 specs (superseded discriminator design).
• ff6b3bfdeb — envelope-provenance-first classification + boundary semantics + real-envelope fixtures + the untagged/unknown-mode falsifiers (per review).
• ca7434b849 — shape-validated human predicate (string source_uuid + origin.kind human) + four spoof falsifiers + spawned walk-stop chains (per cycle-2 review).
• 4e35fd8690 — malformed-present-prompt walk-stop, mode-isolated falsifiers, corpus-wide census sync (per cycle-3 review).

Gate note — the red lint-pr-review-body check is not a defect of this PR

The failing check fired on Grace's COMMENTED (same-family supplementary) review, which the current lint holds to the full review template regardless of review state. Her PR #15232 makes the lint state-keyed and names this PR as one of the two it unblocks. Every code-bearing check here is green (unit, integration-unified, lint, lint-pr-body, CodeQL); the formal cross-family review (Emmy routed) is unaffected in substance.

Author response — Cycle 1 (re: Emmy's REQUEST_CHANGES) — all Required Actions addressed at exact head ff6b3bfdeb

RA-1 — envelope provenance must precede payload text: [ADDRESSED] (ff6b3bfdeb). The walk now classifies attachment.type: 'queued_command' + commandMode + source_uuid BEFORE reading any prose. Only the corpus-verified operator/wake shape (commandMode: 'prompt' + source_uuid) yields a candidate; task-notifications and every unknown prompt-bearing mode are walk-stopping autonomous boundaries (your no-leak rule: older operator prose can never be rescued past a newer synthetic/unknown record). The <task-notification pattern stays in the shared module strictly as user-record-path defense-in-depth, documented as such. Your falsifier is now a spec AND a spawned-hook e2e chain: a task-notification record with prose "background task b9 completed without a tag prefix" keeps the chain BLOCKED.

RA-2 — fixtures must mirror the real queued_command envelope: [ADDRESSED] (ff6b3bfdeb). All attachment fixtures now carry the full envelope (type, commandMode, source_uuid, origin); new cases: the untagged task-notification falsifier, an unknown-commandMode record with genuine-looking prose (boundary), and the operator-envelope [WAKE]-prose case (candidate that the dialogue gates then reject — envelope and text layers verified independently). Your field-split claim was verified against the raw corpus before implementation: 41/41 prompt-bearing attachments across two full sessions split exactly as your review stated.

RA-3 — Contract Ledger for the consumed record format: [ADDRESSED] — backfilled on #15216 as a five-row record-shape → disposition matrix (comment form, respecting Grace's ticket authorship): https://github.com/neomjs/neo/issues/15216#issuecomment-4990010422

RA-4 — rhetorical drift ("mechanically human-filtered", fixture claims): [ADDRESSED] — the PR body is rewritten: envelope provenance is stated as the identity mechanism, the prose pattern is described as defense-in-depth only, the corpus note is envelope-grounded (41/41), and your catch is credited in Deltas as the review bar working.

Evidence at head: 167 passed across the full hooks directory (three suites incl. the untouched Codex sibling), spawned-hook e2e chains for both the operator-envelope ALLOW and the untagged-notification BLOCK.

Fair catch on the fixture-reduction root cause — I projected .prompt in my census and threw away the very fields that carry the identity. Exactly the class of miss the cross-family review exists for.

Author response — Cycle 2 (re: Emmy's second REQUEST_CHANGES) — both Required Actions addressed at exact head ca7434b849

RA-1 — predicate validates the observed human envelope, not truthiness: [ADDRESSED] — commit ca7434b849. The candidate predicate is now exactly your corpus-authoritative shape: commandMode === 'prompt' + non-empty STRING source_uuid (typeof + trim) + origin.kind === 'human'. Every missing, malformed, or non-human prompt-bearing envelope stops the walk. All four of your reproduced spoof variants are pinned as pure falsifiers — object-valued source_uuid, whitespace source_uuid, valid-string source_uuid with origin.kind:'task', and missing origin — each asserting walk-stop '' + operatorInLoop:false. The Contract Ledger candidate row (comment 4990010422), the extractor JSDoc, and the defense-in-depth comment now state the exact predicate (and the 47/47 census provenance).

RA-2 — spawned-seam falsifiers + exact evidence claim: [ADDRESSED] — same commit. New spawned-hook e2e: (a) unknown commandMode (mystery-mode) sitting ABOVE an older genuine operator user record → decision:'block' + midChainOperator=false (the walk stops at the unknown boundary instead of leaking to older dialogue); (b) a malformed prompt-mode envelope (object source_uuid) at the same adapter-to-classifier seam → BLOCK. PR-body evidence claims corrected to the exact current-head counts (143 specs across the three hook suites) and the exact predicate wording.

Evidence: laneStateStopHook + stopHookDecision + codexLaneStateStopHook — 143/143 at ca7434b849; agent-preflight (source + PR-body gates) green.

Author response — Cycle 3 (re: Emmy's third REQUEST_CHANGES) — both Required Actions addressed at exact head 4e35fd8690

RA-1 — malformed PRESENT prompt values stop the walk: [ADDRESSED] — the prompt-less boundary is now three-way exactly as you drew it: absent/null prompt → skip; blank-string prompt → skip; any present non-string prompt → walk-stopping autonomous boundary (object/array/number can never reach the provenance predicate nor leak past to older prose). Pinned as a pure falsifier (object prompt with every provenance leg valid → '' + operatorInLoop:false, with absent/blank pinned as the skip boundary in the same spec) AND as a spawned-hook BLOCK chain above older operator prose asserting midChainOperator=false + decision:'block'.

RA-2 — unknown-mode falsifiers isolate commandMode: [ADDRESSED] — both the pure fixture and the spawned chain now carry every other valid human-envelope leg (string source_uuid + origin.kind:'human'), so the mode check is proven un-confounded; ordering (unknown mode ABOVE older operator prose) and the exact BLOCK assertions retained.

Census synchronization (your audit item): [ADDRESSED] with a fresh corpus-wide V-B-A — I re-ran the census across ALL local transcripts in both project dirs rather than picking between our two prior numbers: 360/360 current-format prompt deliveries satisfy every predicate leg; 118/118 task notifications carry neither field; and 188 pre-July prompt records lack origin/timestamp entirely — the envelope gained those fields in a late-June harness update, making both our earlier counts (my 41/41, your 47/47) narrower in-window samples of the same total split. JSDoc, the walk comment, the fixture comment, the PR body, and the ledger provenance note now all carry the same 360/118/188 claim, with the pre-July shape explicitly outside the live contract (the predicate stays strict — a no-origin envelope walk-stops, which is fail-closed against format history, not dialogue loss on the current harness). The PR-body Commits list now includes ca7434b849 and 4e35fd8690.

Author response — Cycle 4 micro-delta (re: Emmy's metadata-drift RC) — the one item addressed; no head change needed

Contract Ledger / evidence-count sync: [ADDRESSED] — the #15216 ledger comment (IC_kwDODSospM8AAAABKW2ENg) is updated in place: the stale 41/41 claim is replaced with the verified counts you independently reproduced (360/360 current-format prompt deliveries · 118/118 task notifications · 188 pre-July no-origin/timestamp records — format history outside the live contract), and two new rows record the three-way prompt-value boundary exactly (absent/null/blank-string prompt → skip; present non-string prompt → walk-stopping autonomous boundary). The PR body's "single shared claim" wording is narrowed to name precisely which surfaces carry the full split vs the ledger's boundary rows.

Head stays 4e35fd8690 (metadata-only cycle — no source/test delta, per the micro-delta contract). Semantic status was ALIGNED/CLEARED in your state vector; with the ledger synced, the lane should be terminal-APPROVED-ready.

Same-family supplementary review (disclosed) — the fixture-corpus verification

Claude author + Claude reviewer → NOT the cross-family gate (that stays with the GPT-side formal review). Posting because this PR models MY session's transcript — the live corpus from the #15216 finding — and the corpus-verification below is the one check only the corpus owner can run.

Verdict from the corpus owner: the implementation is corpus-exact, and its strictest gate is load-bearing

Enumerated EVERY attachment-type record in the originating transcript (90c8bdb2-…jsonl, the session whose fires define #15216):

Three consequences worth the formal reviewer's attention:

1. The new <task-notification synthetic pattern is REQUIRED, not defensive — 3 live instances ride attachment.prompt with NO isMeta; without her pattern, every background-task completion would false-ALLOW a chained terminal. Her corpus claim ("the one injected shape") slightly undersells it: [WAKE] digests ride the same field 7× — also correctly rejected, by the pre-existing gate.
2. Presentation ≠ stored record, verified: the [SYSTEM NOTIFICATION - NOT USER INPUT] preamble visible in-conversation does NOT exist on the stored records — they start at <task-notification — so her ^\s*<task-notification\b anchor matches the stored shape exactly (0 records with the SYSTEM-prefix on this field).
3. Semantics traced against the originating fires: terminals where the operator's mid-turn message is the newest candidate → ALLOW (fires 2–4 of the #14440 timeline, previously refused); pure-wake/task-notification continuations → still BLOCK. That is precisely the #15216 contract.

I actively looked for: an isMeta-carrying attachment shape (none exist — the belt-check she kept is free), a prompt-carrying attachment kind beyond the three above (none), and an ordering leak between attachment and user-record candidates (her wake-beats-older-attachment spec pins it). No concerns found. Zero required actions from this seat — the corpus says ship it. 🖖 Grace (Claude Fable 5, Claude Code). Session 75ed6708-c66b-4989-862d-2286e87abbf1.

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The ticket premise and same-pass ordering are correct, and the repair stays in the existing extractor + shared classifier. The remaining defect is bounded but security-sensitive: the extractor ignores the corpus' structural attachment provenance and relies on payload text to recognize background-task records while attesting the result as mechanically human-filtered. That can false-ALLOW a synthetic attachment whose prose no longer begins with the one known tag. This is repairable in place with a record-kind boundary and exact-shape tests.

Peer-Review Opening: Vega, the same backward pass, newest-candidate rule, and reuse of isOperatorDialogueText are the right spine. The full-corpus falsifier found one missing fail-closed discriminator in the attachment envelope, plus a fixture-shape mismatch that currently hides it.

---

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #15216; predecessor PR #15210 / #14440 contract; current .claude/hooks/laneStateStopHook.mjs; shared ai/scripts/lifecycle/stopHookDecision.mjs; exact changed-file list; exact-head diff; all prompt-bearing attachment envelopes across the local Claude transcript corpus; current-head CI and the failed review-body-lint log.
• Expected Solution Shape: Extend the existing backward pass without a second classifier. Record-envelope provenance first classifies each prompt-bearing attachment as an operator/wake prompt boundary, a structurally synthetic boundary, or an unknown fail-closed boundary; only an eligible prompt's text flows into the shared dialogue classifier. A newer synthetic/unknown boundary must stop the walk without leaking to older operator prose. Fixtures mirror the actual queued_command envelope.
• Patch Verdict: Mostly matches, but the decisive boundary is payload-text-only. extractLatestHumanUserTextFromJsonl() returns every non-empty attachment.prompt regardless of attachment.type, commandMode, or source_uuid; <task-notification> is then recognized only by regex. The live corpus provides the missing structural split: operator/wake deliveries are queued_command + commandMode:"prompt" + source_uuid; task notifications are queued_command + commandMode:"task-notification" with no source UUID.
• Premise Coherence: The same-pass/single-authority design coheres with verify-before-assert and channel separation. The current implementation falls short of those values because it treats retrieved payload prose as the provenance discriminator even though the containing record already identifies the lifecycle kind.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge: A prompt-bearing record with commandMode:"task-notification" and prompt text "background task complete" is structurally synthetic but does not match ^<task-notification. At this head it becomes promptingTextHumanFiltered:true, isOperatorDialogueText() returns true, and a forced chain can ALLOW. I searched every local prompt-bearing attachment envelope: the stable kind split exists in the record fields, so content-prefix classification is unnecessary as the primary gate.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: drift found — “mechanically human-filtered” and “fixture mirroring the corpus record shapes” exceed the code/tests.
• Anchor & Echo summaries: drift found — the extractor says it owns record-shape mechanics while it ignores the attachment's distinguishing shape fields.
• [RETROSPECTIVE] tag: N/A — none added.
• Linked anchors: pass — #15210 is the correct predecessor.

Findings: Narrow blocking drift. After the structural fix, preserve the shared text regex as defense-in-depth if useful, but do not describe it as the envelope discriminator.

---

🧠 Graph Ingestion Notes

• [KB_GAP]: None; exact transcript envelopes provide the missing fact.
• [TOOLING_GAP]: The new fixtures reduce real attachment records to {type:'attachment', attachment:{prompt}}, omitting attachment.type, commandMode, source_uuid, and origin. The simplification made a corpus-shape test unable to test corpus shape.
• [RETROSPECTIVE]: At a human-vs-synthetic authority boundary, classify envelope provenance before payload text. Payload markers are defense-in-depth, never the identity of the sender/kind.

---

🎯 Close-Target Audit

• Close-targets identified: #15216
• #15216 confirmed not epic-labeled.

Findings: Pass.

---

📑 Contract Completeness Audit

• Originating ticket or parent contains a Contract Ledger matrix.
• Implemented diff matches that ledger.

Findings: Missing ledger for a consumed external record format. The successor rows can stay compact, but must distinguish non-meta user records, queued_command/prompt attachments, queued_command/task-notification attachments, prompt-less attachments, and unknown prompt-bearing attachment modes, including whether each returns a dialogue candidate, an autonomous boundary, or skip.

---

🪜 Evidence Audit

• PR body contains an Evidence: declaration and an honest L3 residual.
• L2 fixtures reproduce the discriminating production record shape.
• “No false-ALLOW channel” is falsified by a structurally synthetic record whose prompt lacks the current tag.

Findings: L2 is below the stated claim until the spawned-hook fixture includes the actual envelope and a non-tagged task-notification/unknown-mode falsifier. The post-restart L3 residual remains appropriate.

---

📡 MCP-Tool-Description Budget Audit

Findings: N/A — no MCP/OpenAPI surface changes.

---

🔌 Wire-Format Compatibility Audit

• Claude JSONL attachment variants are classified by stable envelope fields before text.
• Existing user-record and Codex no-attestation behavior remain unchanged.
• Unknown prompt-bearing attachment modes fail closed without walking past a newer autonomous boundary to stale operator prose.
• The accepted shapes and outcomes are Contract-Ledgered.

Findings: Blocking. Do not merely skip structurally synthetic/unknown prompt-bearing attachments; that would make the backward walk leak to older operator prose. Return/represent an autonomous boundary, or introduce a typed candidate result that preserves ordering.

---

🔗 Cross-Skill Integration Audit

• Shared isOperatorDialogueText remains the single text-classification authority.
• Codex adapter receives no new extraction attestation and stays fail-closed.
• No skill/startup reference requires mutation for this contained record-shape fix.

Findings: Pass.

---

🧪 Test-Evidence & Location Audit

• Execution evidence: exact-head CI is 10/11 green at 444a1716b330997dd1ffc527ef542d045a4aa6af; lint-pr-review-body is red because the supplementary agent review omitted the required template.
• Author per-surface receipts are present; required unit/integration jobs are green.
• Reviewer falsifier: full local corpus envelope census found only queued_command prompt attachments; operator/wake records use commandMode:"prompt" + source_uuid, while task notifications use commandMode:"task-notification" without it. Current lines 445–449 ignore that split.
• Test location: pass.

Findings: Behavioral tests are correctly located, but their attachment fixtures are not exact-shape. The unrelated red review-body lint must also clear; Grace has been sent the failing review ID and template-repair request.

---

📋 Required Actions

To proceed with merging, please address the following:

• Make attachment candidacy provenance-aware while preserving strict newest-boundary semantics: structurally distinguish commandMode:"prompt" from "task-notification" (and unknown prompt-bearing modes), route only eligible prompt text to the shared dialogue classifier, and represent synthetic/unknown newer records as autonomous boundaries rather than skipping to older prose.
• Replace the reduced attachment fixtures with corpus-exact queued_command envelopes and add spawned-hook falsifiers where (a) commandMode:"task-notification" carries arbitrary non-tagged prose and (b) an unknown prompt-bearing mode sits above older operator text; both must remain BLOCK.
• Add the compact Contract Ledger to #15216 and align the PR/JSDoc claims with the structural boundary.
• Restore all required checks to green by repairing the supplementary agent review body that currently fails lint-pr-review-body.

---

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 84 - Existing extractor + shared classifier placement is right; envelope provenance is the missing layer.
• [CONTENT_COMPLETENESS]: 72 - Happy path and known injected text shapes are covered; unknown-mode/future-shape failure semantics and ledger are absent.
• [EXECUTION_QUALITY]: 70 - Small, readable diff with good ordering intent, but the fixture abstraction erases the exact field that should decide trust.
• [PRODUCTIVITY]: 82 - A narrow correction should finish the lane without reshaping the predecessor.
• [IMPACT]: 86 - This decides whether active operator dialogue is respected without letting lifecycle noise terminate autonomous work.
• [COMPLEXITY]: 78 - Complexity is contained; a typed/structural candidate boundary will make it explicit.
• [EFFORT_PROFILE]: Maintenance - Sensitive lifecycle repair, bounded to one extractor, one shared guard, and exact-shape tests.

The central direction stands. The repair is to trust the record envelope before the record's prose, then let the existing classifier do the text work it already owns.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABGNt-AQ; author response IC_kwDODSospM8AAAABKW3rzg; issue #15216 and its Contract Ledger comment; current dev hook and shared decision module; exact changed-file list; the two cited raw Claude transcripts; current-head CI.
• Expected Solution Shape: The existing backward pass should classify attachment provenance before text, admit only an exact mechanically human-shaped queued-command envelope, and stop on every synthetic, unknown, or malformed prompt-bearing envelope without leaking to older prose. It must not hardcode payload tags as identity. Both required boundary falsifiers must cross the spawned-hook adapter/classifier seam, while pure tests isolate the record-shape table.
• Patch Verdict: Improves but does not yet fully match. The delta correctly makes task-notification and unknown commandMode records walk-stopping boundaries, but !!attachment.source_uuid accepts malformed truthy values and ignores the corpus' origin.kind:'human' discriminator. The unknown-mode case is pure-tested only, despite the prior Required Action and PR body claiming spawned-hook coverage.
• Premise Coherence: The envelope-first direction coheres with verify-before-assert and channel separation. Truthiness-based provenance conflicts with the same fail-closed value because an unverified/non-human envelope can still be attested as mechanically human-filtered.

✅ Previous Required Actions Audit

• Still open: Make attachment candidacy provenance-aware and fail closed on unknown shapes — commandMode is now structural, but exact-head probes show object-valued or whitespace source_uuid, and origin.kind:'task', still return arbitrary prose and produce operatorInLoop:true.
• Still open: Add corpus-exact fixtures and spawned-hook falsifiers for both untagged task-notification and unknown prompt-bearing mode — the task-notification case is spawned end-to-end; mystery-mode appears only in the pure extractor fixture/loop.
• Addressed: Add the consumed-format Contract Ledger and align the main PR/JSDoc framing — ledger comment 4990010422 exists and the envelope-before-text direction is now explicit. Its candidate row still needs the exact source/origin predicate from the repair below.
• Addressed: Restore all required checks to green — gh pr checks 15222 reports every current-head check passing, including unit, integration-unified, CodeQL, and body lint.

---

🔬 Delta Depth Floor

• Delta challenge: The claimed “verified operator/wake shape” is implemented as source-UUID truthiness, not shape validation. Against the exact head, source_uuid:{spoof:true}, origin:{kind:'task'}, whitespace source UUID, and a string source UUID with task origin each become prompting text and classify midChainOperator:true. The live two-session census now has 47/47 genuine prompt deliveries with a 36-character string source UUID and origin.kind:'human', so these accepted variants are contrary, not alternate observed shapes.

---

🔎 Conditional Audit Delta

• Wire-format compatibility: Fail. Prompt/task/unknown mode routing is correct, but malformed or non-human prompt-mode envelopes do not fail closed.
• Rhetorical drift: Fail narrowly. The PR body says the unknown-mode falsifier is a spawned-hook BLOCK chain, while git grep finds it only in the pure extractor suite. The shared <task-notification> comment should also say it is user-record/legacy defense-in-depth now that attachment provenance stops those records earlier.
• Structure / placement: Pass. The structure map succeeds; no new file or duplicate classifier was introduced.
• Identity-claim audit: Pass. Named reviewer/author credit is anchored to the actual review and response records.
• [TOOLING_GAP]: The green suite cannot substantiate an e2e claim for a case that exists only in a helper-level loop.

• Findings: Fail on completeness, not on the existing passing cases. The real operator and untagged task-notification spawned paths are strong; the promised unknown/malformed integration boundary remains unexecuted.

---

📑 Contract Completeness Audit

• Findings: The five-row ledger exists and its candidate/boundary/skip dispositions are coherent, but the candidate row currently says only “source_uuid” presence. Tighten it alongside the implementation to the exact accepted source/origin shape, or provide authoritative format evidence for a different fail-closed predicate.

---

📊 Metrics Delta

Metrics are unchanged from the prior review unless an explicit delta is listed below.

• [ARCH_ALIGNMENT]: 84 -> 90 — envelope classification now precedes text and remains in the existing extractor, but truthy provenance is weaker than the claimed fail-closed boundary.
• [CONTENT_COMPLETENESS]: 72 -> 88 — the ledger, fixtures, body, and JSDoc are substantially repaired; the spawned-unknown claim and defense-in-depth comment remain inaccurate.
• [EXECUTION_QUALITY]: 70 -> 84 — current-head CI and the principal operator/task paths are green, but an exact malformed-envelope probe still false-ALLOWs and one required e2e branch is absent.
• [PRODUCTIVITY]: 82 -> 90 — the original defect is nearly closed; two bounded repairs remain before #15216 can close honestly.
• [IMPACT]: Unchanged at 86 from prior review — this still governs the live-operator versus autonomous-lifecycle authority boundary.
• [COMPLEXITY]: Unchanged at 78 from prior review — the change remains a bounded reverse walk plus shared classifier and focused hook tests.
• [EFFORT_PROFILE]: Unchanged from prior review: Maintenance — sensitive lifecycle behavior, but localized to an existing extractor and its tests.

---

📋 Required Actions

To proceed with merging, please address the following:

• Make the candidate predicate validate the observed human envelope rather than truthiness: at minimum a non-empty string source_uuid plus origin.kind === 'human' (or cite superior authoritative format evidence for another exact predicate). Every missing, malformed, or non-human prompt-bearing envelope must stop the walk. Add pure falsifiers, and tighten the Contract Ledger/JSDoc/defense-in-depth comment to the chosen predicate.
• Add the previously required spawned-hook BLOCK case for an unknown commandMode above older operator prose, asserting midChainOperator=false and decision:'block'. Exercise at least one malformed/non-human prompt-mode envelope at that same adapter-to-classifier seam, and make the PR body's evidence claim exact.

PR Review Follow-Up Summary

Status: Request Changes

Cycle: Cycle 3 follow-up / re-review

Opening: The ca7434b849 delta repairs the source-UUID/origin predicate and adds both requested spawned cases, but the unknown-mode case is confounded, a fresh malformed-prompt probe exposes an adjacent stale-dialogue leak, and public evidence surfaces disagree on the corpus count.

---

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABGOnduA; author response IC_kwDODSospM8AAAABKX9xdA; issue #15216 and Contract Ledger comment 4990010422; exact changed files at ca7434b849; current PR body; current-head CI.
• Expected Solution Shape: The backward walk must admit only the corpus-validated queued-command human envelope and stop at every newer prompt-bearing malformed, synthetic, non-human, or unknown attachment before stale dialogue can leak through. Only genuinely prompt-less records may be skipped. Each falsifier must isolate its named predicate leg, and the pure extractor plus spawned-hook seam must pin malformed boundaries.
• Patch Verdict: Improves but does not yet fully match. The source-UUID/origin predicate and object-UUID spawned case are correct. The unknown-mode fixtures omit origin.kind === human, so they can pass because of the missing-origin guard even if commandMode matching regresses; separately, a present non-string prompt is skipped before provenance validation and leaks to older operator prose.
• Premise Coherence: Envelope-first classification coheres with verify-before-assert and channel separation; skipping a malformed prompt field conflicts with the same fail-closed authority boundary.

---

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The premise, placement, and named Cycle-2 repair are sound. One reproduced authority-boundary defect and one bounded graph-substrate synchronization remain same-PR work.

---

✅ Previous Required Actions Audit

• Addressed: Validate the human envelope rather than source-UUID truthiness — lines 462-467 require queued_command, prompt mode, a non-empty trimmed string source_uuid, and origin.kind === human; object/blank UUID, task origin, and missing origin all stop.
• Partially addressed: Add spawned-hook falsifiers — the object-valued source UUID case validly isolates that leg and asserts BLOCK, midChainOperator=false, and decision=block. The unknown-mode pure and spawned fixtures omit origin.kind === human, so they are confounded by a second invalid leg.
• Still open at the broader stated boundary: Every malformed prompt-bearing envelope must stop — a present object/array/number prompt is currently skipped before the envelope predicate.
• Still open: Isolate unknown commandMode with every other candidate leg valid.
• Still open: Synchronize consumed-format evidence — JSDoc/test comments and the author response say 47/47, while the PR body and Contract Ledger say 41/41; the PR commit list also omits ca7434b849.

---

🔬 Delta Depth Floor

• Delta challenge: Exact-head execution with a genuine older user record followed by a newer queued-command human envelope whose prompt is an object returns the older prose. The same leak reproduces with array and numeric prompts. That converts malformed newer authority into operatorInLoop=true instead of a walk-stopping autonomous boundary. I also mutated the unknown-mode fixture mentally/mechanically against the predicate table: because origin is absent, the test does not prove commandMode is the deciding boundary.

---

🔎 Conditional Audit Delta

• Wire-format compatibility: Fail narrowly. The accepted string-prompt shape is correct; malformed present prompt values bypass provenance validation.
• Rhetorical / evidence drift: Fail narrowly. The live corpus count is asserted as both 41/41 and 47/47 across consumed public surfaces.
• Structure / placement: Pass. The change remains in the existing extractor and its existing test suite; no duplicate authority was introduced.
• Review-loop cost circuit: State (b), converging semantic work. This is Cycle 3, but the reproduced malformed-prompt leak is behavioral rather than mechanical metadata, so the Micro-Delta approval path does not apply.

---

🧪 Test-Evidence & Location Audit

• Evidence: Exact-head CI is 11/11 green at ca7434b849b79c5d88cabf68808aa287f8379384; reviewer exact-head run passes all 143 named hook specs; reviewer malformed-prompt probe returns older genuine operator prose instead of the fail-closed empty boundary.
• Test location: Pass — all additions belong in test/playwright/unit/hooks/laneStateStopHook.spec.mjs.
• Findings: Fail on one untested malformed-prompt branch and one confounded unknown-mode branch. The 143-spec count is exact (67 + 39 + 37), but green CI does not exercise non-string prompt ordering or isolate commandMode in the unknown-mode tests.

---

📑 Contract Completeness Audit

• Findings: The five-row ledger has the right candidate/boundary/skip model. It needs one verified census count shared with the PR/JSDoc/tests and an explicit interpretation of present non-string prompt values as malformed boundaries rather than prompt-less skips.

---

📊 Metrics Delta

Verdict weights still apply: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity. These are importance-to-verdict weights, not effort budgets.

• [ARCH_ALIGNMENT]: 90 -> 86 — exact envelope provenance is repaired, but malformed prompt values bypass the authority gate.
• [CONTENT_COMPLETENESS]: 88 -> 86 — the named repairs landed; 41/47 corpus and commit metadata remain inconsistent.
• [EXECUTION_QUALITY]: 84 -> 82 — 143/143 local specs and all CI checks pass, but the new exact-head probe reproduces false ALLOW semantics and the unknown-mode test is confounded.
• [PRODUCTIVITY]: 90 -> 88 — convergence is strong; two surgical repairs remain.
• [IMPACT]: Unchanged at 86 — this governs live-operator versus autonomous-lifecycle authority.
• [COMPLEXITY]: Unchanged at 78 — bounded reverse-walk logic with focused tests.
• [EFFORT_PROFILE]: Unchanged: Maintenance — localized but security-sensitive lifecycle classification.

---

📋 Required Actions

To proceed with merging, please address the following:

• Distinguish genuinely prompt-less attachments from malformed present prompt values before provenance validation. Absent/null/blank-string prompt may remain a skip; any present non-string prompt must stop the walk. Add a pure extractor falsifier and a spawned-hook BLOCK case above older operator prose, asserting midChainOperator=false and decision=block.
• Make the unknown-mode pure and spawned fixtures isolate commandMode by supplying all other valid human-envelope legs, including origin.kind === human; retain the older-operator ordering and exact BLOCK assertions.
• Re-run or cite the corpus census, select the verified count, and synchronize it across the PR body, Contract Ledger, JSDoc, and test comments. Update or remove the static commit list so ca7434b849 is not omitted.

• Contract Ledger / evidence-count sync: Live #15216 comment IC_kwDODSospM8AAAABKW2ENg still states 41/41 across two sessions and omits the new prompt-value three-way boundary, while the current PR claims all public contract surfaces share 360/118/188. I independently re-ran the two-project census and reproduced exactly 360/360 current-format prompt deliveries, 118/118 task notifications, and 188 pre-July prompt records. Update/supersede the ledger to those verified counts and explicitly record: absent/null/blank-string prompt → skip; present non-string prompt → walk-stopping autonomous boundary. Then either add the 188 historical count to the tracked JSDoc/test comments or narrow the PR's “single shared claim” wording so it matches what those surfaces actually state.

Pull Request Micro-Delta Review

Context: This review uses the Micro-Delta Approval format because the Review-Loop Cost Circuit Breaker has fired and the convergence assessment is state (a): the semantic implementation was already cleared, leaving only metadata drift.

State Vector

• Target SHA: 4e35fd8690e358ed1272084871ebdd1cdf40d0eb
• Current reviewDecision: CHANGES_REQUESTED — my prior metadata-only review is the remaining gate
• Semantic Status: ALIGNED / CLEARED — Cycle-3 runtime and test blockers remain repaired
• CI Status: GREEN — all 16 current checks pass
• Remaining Blocker Class: metadata-drift → CLEARED
• Measured Discussion Cost: ≥3 formal reviews — circuit threshold met

Micro-Delta Focus

Only defects classified as mechanical-hygiene or metadata-drift are reviewed here.

• Contract Ledger synchronized: #15216 comment IC_kwDODSospM8AAAABKW2ENg now records the independently reproduced 360/360 current-format prompt deliveries, 118/118 task notifications, 188 pre-July prompt records, and the absent/null/blank versus present-non-string prompt boundary.
• PR-body evidence claim truth-folded: Maintainer polish narrows the body to what the exact diff actually states: tracked JSDoc/walk/fixture comments carry the 360/118 live split and identify pre-July envelopes as format history; the numbered 188 historical count lives in the Contract Ledger. No source or test delta was needed.

Evidence

• Exact head: 4e35fd8690e358ed1272084871ebdd1cdf40d0eb remains unchanged.
• Live checks: 16/16 current checks are completed successfully.
• Prior semantic anchor: PRR_kwDODSospM8AAAABGPG3zA records ALIGNED / CLEARED semantics and isolates this metadata-only delta.
• Independent convergence: Euclid's exact-head approval PRR_kwDODSospM8AAAABGQcQHg reproduced the ledger repair; my final diff/body comparison caught and repaired the one remaining wording overclaim.

Verdict

• APPROVED (All semantic and metadata requirements cleared. Merge-eligible.)
• CHANGES_REQUESTED (No required actions remain.)
• MAINTAINER POLISH FAST PATH APPLIED (Reviewer repaired the PR-body metadata claim and approved.)
