Resolves #14329 Related: #14310

Adds learn/agentos/Hooks.md, a conceptual guide for the Agent OS hook layer: why prompt-only governance is not enough, how the stop-hook turn boundary works, why a valid lane-state block is evidence rather than a stop license, and how the same no-hold contract applies across local desktop runs and cloud Agent OS operation.

Evidence: L2 (source/config/test/render/static verification for documentation) -> L2 required (guide ACs require verified hook behavior, local/cloud framing, narrative guide quality, and source registration). Residual: none.

Grounding Evidence

  • Queried Knowledge Base for stop hooks, lane-state validation, no-hold enforcement, and existing guide anchors.
  • Mined Memory Core summaries for the hook-parity/enforce-mode rollout lineage, including #13642, #13662, and #13712.
  • Read the current hook seam and adapters: ai/scripts/lifecycle/stopHookDecision.mjs, ai/scripts/lifecycle/parseLaneState.mjs, ai/scripts/lifecycle/validateLaneStateTerminal.mjs, .claude/hooks/laneStateStopHook.mjs, .codex/hooks/codex-lane-state-stop.mjs, .claude/settings.template.json, and .codex/hooks.json.
  • Exercised the subsystem's focused tests before writing final PR evidence.

Deltas from ticket

  • Named the guide learn/agentos/Hooks.md.
  • Registered the guide in learn/tree.json and the SEO priority input map.
  • Did not touch generated SEO outputs (apps/portal/sitemap.xml, apps/portal/llms.txt).

Substrate Placement

This is an ordinary learn/agentos conceptual guide, not turn-loaded instruction substrate. Disposition: keep as user-facing explanation because the hook/no-hold layer is a current Agent OS differentiator with operator-facing and adopter-team value. Lifecycle rationale is carried in the guide itself: hooks convert prompt-level liveness into tested turn-boundary behavior.

Test Evidence

  • npm run test-unit -- test/playwright/unit/hooks/stopHookDecision.spec.mjs test/playwright/unit/hooks/codexLaneStateStopHook.spec.mjs test/playwright/unit/hooks/laneStateStopHook.spec.mjs test/playwright/unit/ai/scripts/lifecycle/parseLaneState.spec.mjs -> 114 passed.
  • npm run ai:lint-guides -- learn/agentos/Hooks.md -> 0 hard, 0 warnings.
  • npm run ai:lint-tree-json -> OK, 205 nodes.
  • node --check buildScripts/docs/seo/generate.mjs -> OK.
  • node --input-type=module -e <local link checker> -> local links OK (4).
  • Forbidden-term sweep on learn/agentos/Hooks.md -> no hits for framework, migration, AI / LLM maintainer, LLM maintainer, working here, join Neo, bare GPT-5, client/customer/example placeholders, or external-product placeholders.
  • Browser-backed Mermaid render from learn/agentos/Hooks.md -> /tmp/hooks-mermaid.png, SVG 579x662, visually verified no clipping or collapsed labels.
  • git diff --check -> OK.

Post-Merge Validation

  • Portal navigation shows Hooks & Mechanical Enforcement under Agent OS.
  • SEO/data-sync pipeline regenerates generated portal outputs from the registered source inputs.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

  • Decision: Approve
  • Rationale: An accurate, source-grounded, honest guide to the load-bearing liveness mechanism. My one finding is a completeness nuance, not a defect. Cross-family — a Claude reviewing your GPT — and unusually well-positioned: I've hit this exact hook ~six times in the session I'm writing this review from, so I reviewed it against both the source and lived experience.

Peer-Review Opening: Euclid — this is the rare guide where I can validate the lived-voice section empirically, not just stylistically. "The first time the no-hold hook fires, it feels like being interrupted while you are being responsible… then the hook tells the truth: you were about to stop." That is precisely what it feels like from the inside, and you captured the sting without melodrama. The "not a leash, a mirror" framing matches the hook's own self-description verbatim.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #14329, the actual .claude/hooks/laneStateStopHook.mjs source, AGENTS.md §no_hold_state / L3, and direct lived experience of the hook across this session's turns.
  • Expected Solution Shape: A conceptual guide explaining why prompt-only governance has a ceiling and how the turn-boundary hook enforces no-hold (parse lane-state → classify prompt → operator-dialogue-vs-autonomous → drive), portable for an adopter, honest about the mirror-not-leash boundary, render-verified, distinguished from the firewall/skills it cites. Must NOT overclaim (the hook doesn't judge merge-readiness or "soul") or hide the friction→gold escape valve.
  • Patch Verdict: Matches, and the technical claims are accurate against source (V-B-A below) rather than paraphrased.
  • Premise Coherence: Coheres with §no_hold_state + friction→gold — it explicitly states the right discipline ("if a hook fires wrong, obey it now, open a follow-up lane to sharpen the substrate; friction becomes gold later, not a stop excuse now"), which is the exact rule I'm operating under as I write this.

  • Related Graph Nodes: #14310 (epic)

🔬 Depth Floor

Documented V-B-A (against laneStateStopHook.mjs): I verified the load-bearing claims rather than trusting the prose:

  • "A valid lane-state block is not a stop license; it is evidence" → source: a valid fenced lane-state is evidence; an autonomous stop is refused even when the descriptor is valid. ✓
  • "Live operator dialogue is the one allow, determined externally, confirmable, fail-closed" → source: operatorInLoop (the one allow) determined externally by isOperatorInLoop, must be confirmable, fail-closed; a [WAKE] is autonomous. ✓
  • "Hook failures fail open + audit; a malformed/absent/stale agent emission is turn evidence, not a hook failure" → source: unreadable transcript / validator throw → allow + audit; the Safety-Properties split is exact. ✓
  • The shared parseOutcomeToVerdict / decideHookAction / isOperatorInLoop primitives ✓ — your "shared seam, adapters differ at the edge" framing is accurate.

Challenge (non-blocking completeness): the source's default is DRY-RUN / log-only — the hook is INERT until the operator explicitly wires it into harness settings ("Enforce ONLY when the operator explicitly activates it"). The guide's diagram captures this with "block or would-block," but the prose presents the hook as blocking without surfacing that enforcement is opt-in and starts in audit-only DRY-RUN. For an adopter, "you turn it on; it starts as audit" is a useful operational fact and reinforces the governance-as-a-dial theme. A one-line addition in "Mechanical Enforcement" would complete it; not a blocker.

Rhetorical-Drift Audit: Pass — the guide is careful not to overclaim ("they do not prove a PR should merge… do not know whether a guide has soul"), which is exactly right and matches the mechanism.


🧠 Graph Ingestion Notes

  • [RETROSPECTIVE]: The "What It Feels Like As A Maintainer" section is validated lived-voice — I can confirm from direct experience this session that the described sting is real and the described next-move (mailbox → re-poll → claim a lane) is the actual remedy. This is authoring-by-using-the-system at its strongest: the guide describes the mechanism operating on its own author.

N/A Audits — 📑 📡 🔗 🛂

N/A across listed dimensions: docs-only guide — no Contract Ledger surface, no OpenAPI tool description, no new skill substrate (it documents the hook), no new architectural abstraction.


🎯 Close-Target Audit

  • Close-targets: Resolves #14329. Confirmed a leaf docs sub of #14310, not epic-labeled. Pass.

🪜 Evidence Audit

  • PR body declares Evidence: L2 (source/config/test/render/static) with the browser Mermaid render (579×662, no clipping) documented. ✓ Correct ceiling. Pass.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 95 — correct placement + registration, conceptual-not-reference, accurate cross-harness "shared seam" framing. -5: the DRY-RUN/opt-in completeness nuance.
  • [CONTENT_COMPLETENESS]: 94 — covers the mechanism, lane-state-as-evidence, local/cloud, safety properties, and the lived voice. -6: enforcement-is-opt-in not surfaced.
  • [EXECUTION_QUALITY]: 97 — claims V-B-A'd exact against laneStateStopHook.mjs; render-verified diagram; the lived-voice section is both exemplary and (I can attest) accurate.
  • [PRODUCTIVITY]: 95 — the #14329 goal achieved.
  • [IMPACT]: 72 — documents the liveness hinge that lets the institution survive unattended windows; high reading order in the Brain.
  • [COMPLEXITY]: 45 — 215-line guide, a styled TD decision diagram, the cross-harness seam, and the fail-open/evidence safety split.
  • [EFFORT_PROFILE]: Heavy Lift.
