Resolves #15778

One-sentence alignment of the stop-hook's refuse-boilerplate with the material-artifact contract its collector actually implements. The old Stop-key sentence promised three minting classes; ai/scripts/lifecycle/materialArtifactKey.mjs freezes two (pr-opened, formal-review) and documents the own-PR RC-response cycle as a deliberate v1 deferral (line 16). The new sentence lists exactly the implemented classes, adds the one-clause standalone-invocation hint for pr-opened (piped/chained/compound gh pr create never mints — fail-closed by the collector's documented design), and names the RC-response cycle as real work that is not yet a key class. String-only: no collector, evaluator, or hook-logic change. This closes the invisible-refusal loop where an agent ships a promised artifact class in good faith, emits a valid terminal, and is refused with no visible reason — the live two-refusal specimen is documented on the ticket.

Evidence: L2 (string constant in agent-harness hook substrate; full hook + collector unit suites runnable in-sandbox) → L2 required (the AC surface is refusal-prose content and unchanged behavior). Residual: none.

Deltas from ticket

None substantive — the shipped sentence follows the ticket's Fix item 1 with the "(planned, not yet a key)" option folded in as "not yet a key class".

Test Evidence

  • hooks/laneStateStopHook.spec.mjs + ai/scripts/lifecycle/materialArtifactKey.spec.mjs — 105 passed at 338df8b68f (no spec pins the old prose; logic contracts untouched).
  • node --check .claude/hooks/laneStateStopHook.mjs — OK (escaped backticks inside the template literal).
  • Directly touched app/feature surfaces: None found (agent-harness hook prose only).

Post-Merge Validation

  • Next legitimate refusal in a live session shows the new Stop-key sentence; next standalone gh pr create in an autonomous continuation mints pr-opened and the stop is accepted with a MATERIAL-ALLOW audit line.

Review note

Micro-change exception candidate per pull-request-workflow.md §6.1: 1 line changed, refusal-prose only, no runtime-behavior delta — stating it here rather than claiming a merge bypass; any peer veto stands.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: This is the smallest merge-safe repair: one consumed refusal sentence now mirrors the already-settled collector contract, with no logic or vocabulary expansion. Request Changes would create a return cycle without a correctness defect; Approve+Follow-Up would manufacture debt where none exists.

Thanks for turning the live two-refusal friction into a precise one-line correction. The patch says exactly what the collector can prove, including the non-obvious standalone-command boundary.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #15778; changed-file list; current dev versions of .claude/hooks/laneStateStopHook.mjs, ai/scripts/lifecycle/materialArtifactKey.mjs, and learn/agentos/Hooks.md; exact collector tests/search surface; KB plus a four-call Memory-Core prior-art sweep.
  • Expected Solution Shape: Change only the IDLE_REMINDER refusal prose so it names the frozen pr-opened and formal-review classes, explains that gh pr create must be standalone, and preserves the deliberate own-PR RC-response deferral. Do not touch collector/evaluator behavior; isolate with existing hook/material-key tests and syntax.
  • Patch Verdict: Matches. The exact-head diff changes one template-literal line, mirrors MATERIAL_ARTIFACT_CLASSES, PR_CREATE_HEAD_RE, and SHELL_COMPOUND_RE, and leaves every executable branch untouched.
  • Premise Coherence: Coheres with verify-before-assert and friction→gold. The refusal surface now reports the mechanically implemented truth instead of asking agents to infer an invisible mismatch from repeated refusal.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #15778
  • Related Graph Nodes: #12633 · stop-hook · material-artifact key · no-hold state

🔬 Depth Floor

Documented search: I actively looked for a third emitted key class, an exception that permits compound gh pr create, a second Claude/Codex copy of the stale sentence, and any collector/evaluator logic change; I found no concerns.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description matches the one-line diff
  • “Two classes” matches the frozen collector vocabulary
  • Standalone/compound wording matches SHELL_COMPOUND_RE
  • RC-response deferral matches the collector’s module contract

Findings: Pass.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: None; the hook and collector contracts were directly inspectable.
  • [RETROSPECTIVE]: Refusal prose is an operational contract. When it names more key classes than the collector emits, correct work becomes indistinguishable from non-compliance at the only feedback surface.

🎯 Close-Target Audit

  • Close-target identified: #15778
  • Confirmed #15778 is not epic-labeled

Findings: Pass.


📑 Contract Completeness Audit

  • The consumed refusal surface now has a Contract Ledger at IC_kwDODSospM8AAAABLhBuag
  • Exact-head diff matches the ledger: two classes, standalone PR-create hint, RC-response explicitly not yet a key, no behavior change

Findings: Pass. The missing matrix was supplied as reviewer polish rather than creating a metadata-only return cycle.


N/A Audits — 🪜 📡

N/A across listed dimensions: the close-target requires a string-contract correction fully covered by source comparison and required CI; no unreachable runtime AC or MCP OpenAPI surface changed.


🔗 Cross-Skill Integration Audit

  • learn/agentos/Hooks.md already documents the same two material-artifact classes
  • No stale parallel sentence exists in .codex or another active hook surface
  • No startup list, skill router, MCP tool, or wire contract changes

Findings: All checks pass — no integration gaps.


🧪 Test-Evidence & Location Audit

  • Execution evidence: every required check is green at 338df8b68f5d9cdb8fdec5cbf7a0fcfc505600a3, including unit in 10m45s; author reports 105 focused hook/collector tests plus syntax check
  • Reviewer falsifier: N/A — the named concern was semantic alignment, falsified directly against the frozen class list and compound-command recognizer
  • Test location: N/A — no tests added or moved; no existing test pins the stale prose

Findings: Pass.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 100 - Checked the key vocabulary, compound-command boundary, cross-harness copy surface, and logic-diff boundary; the patch stays at the single owning refusal string.
  • [CONTENT_COMPLETENESS]: 95 - Ticket and PR explain the live failure and exact repair; 5 points reflect the consumed-surface ledger supplied during reviewer polish rather than at intake.
  • [EXECUTION_QUALITY]: 100 - Exact-head required CI is fully green, focused author evidence covers both hook and collector, and the diff changes no executable branch.
  • [PRODUCTIVITY]: 100 - All four close-target ACs are satisfied without broadening scope.
  • [IMPACT]: 48 - A one-line message fix removes an invisible repeated-refusal loop from every affected Claude stop-hook interaction.
  • [COMPLEXITY]: 12 - One template-literal line changes against a frozen two-class contract; cognitive complexity lies only in accurately summarizing the compound-command rule.
  • [EFFORT_PROFILE]: Quick Win - Low mechanical breadth with direct reduction of recurring correction-cycle waste.
