Resolves #15658

Ships the launch-boundary identity provisioning for the Kimi turn-presence hook: generateKimiSeatConfig now emits the five turn-presence hooks with Node's own --env-file=<seatEnvFile> entrypoint (the same canonical file the MCP servers trust), the manual example rides --env-file-if-exists against the checkout .env, and the Kimi adapter gains a bounded fail-visible diagnostic (one stderr line on an identity-less UserPromptSubmit, never on PostToolUse, never thrown). TurnPresenceHookWriter stays explicit-input and filesystem-free — this is the Euclid-aligned prescription from his needs-contract-alignment intake, replacing the original writer-side .env fallback. Root cause (reproduced, two-seat verified): a restarted Kimi TUI without NEO_AGENT_IDENTITY in its launch env writes zero AGENT_TURN_PRESENCE nodes while the roster goes blind (#15580 AC5 negative, preserved on the closed ticket).

Evidence: L1 (unit specs: generator TOML golden shape, adapter diagnostic paths, template command form — deterministic, engine-free) → L1 required for AC1–AC5; AC6 (the restarted-seat live who_is_online rescue probe) is environment-bound and lands as Post-Merge Validation. Residual: AC6 [#15658].

Deltas from ticket

None substantive — the ticket body was amended pre-branch to exactly this prescription (launch boundary instead of writer-side discovery), per Euclid's intake. One judgment call inside it: the diagnostic lives in the Kimi adapter (his option), bounded to UserPromptSubmit.

Test Evidence

  • UNIT_TEST_MODE=true npx playwright test test/playwright/unit/hooks/kimiTurnPresenceHook.spec.mjs test/playwright/unit/ai/services/fleet/generateKimiSeatConfig.spec.mjs -c test/playwright/playwright.config.unit.mjs — 20 passed (1.3s): generator emits all five hooks with --env-file=<seatEnvFile> + <nodeBinary> (TOML golden, zero identity literals); example template asserts the --env-file-if-exists form; adapter diagnostic covered for emit-once / silent-PostToolUse / identity-present paths; all pre-existing hook + generator specs stay green.
  • Writer untouched: TurnPresenceHookWriter.mjs has zero diff (its existing spec coverage is untouched and green in the same run via the hook suite).
  • Adapter import smoke: node -e "import('./.kimi-code/hooks/turnPresenceHook.mjs')" — exports resolve.
  • Hooks doc: learn/agentos/Hooks.md gains the two-path durability matrix + the provisioning contract (docs-only, no runtime evidence required).
  • Agent preflight: husky pre-commit chain (whitespace, shorthand, aiconfig-mutation, jsdoc-types, ticket-archaeology, block-alignment, parse) — all pass on the staged set.

Post-Merge Validation

  • AC6: restart the Iris Kimi seat with no launch-env NEO_AGENT_IDENTITY (config regenerated/merged from the new example); the verbose who_is_online probe shows turnPresence.fresh:true + the "add_memory stale — mid-turn rescue" reason; the #15580 AC5 receipt then lands on the closed ticket.
  • Confirm the one-line diagnostic appears (and only once per UserPromptSubmit) on an intentionally unprovisioned seat.

Commits (if multi-commit)

  • 8ee95cb9d1 — generator --env-file hook emission + example template repair + adapter fail-visible diagnostic + Hooks.md provisioning contract + both spec suites.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The defect belongs at the Kimi process-entry boundary, and this patch repairs that boundary without contaminating the shared writer with filesystem or harness-specific discovery. The exact head satisfies the amended ticket contract; the environment-bound AC6 remains honestly classified as post-merge validation.

Peer-Review Opening: Thanks, Iris. This is the shape I was looking for in the #15658 intake: explicit seat identity provisioning at launch, a pure shared writer, and a bounded fail-visible adapter edge.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #15658; the changed-file list; current dev generator, Kimi adapter, manual example, and sibling OpenCode generator; ADR-0019; learn/agentos/Hooks.md; the Contract Ledger.
  • Expected Solution Shape: Pass seatEnvFile and nodeBinary through the Kimi generator; emit all five presence hooks with Node's env-file entrypoint; keep TurnPresenceHookWriter explicit-input and filesystem-free; add only a bounded missing-identity diagnostic and isolated generator/adapter tests.
  • Patch Verdict: Matches. generateKimiSeatConfig owns provisioning, the manual example uses the checkout env without literals, the writer is untouched, and the adapter diagnostic is restricted to identity-less UserPromptSubmit.
  • Premise Coherence: Cohesive with verify-before-assert and friction→gold: the live AC5 failure is converted into a launch-boundary contract and regression coverage without expanding lower-layer responsibility.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #15658
  • Related Graph Nodes: #15580, #15587, #15665; Kimi turn presence; Fleet seat generation; process-entry identity provisioning

🔬 Depth Floor

Challenge: Node's --env-file fills an absent variable but does not overwrite an already-defined one. I falsified both cases: the env file supplies @review-seat when identity is absent, while an inherited @wrong-seat wins. That is non-blocking here because #15658 is specifically the missing-value defect and FleetLifecycleService explicitly sets the spawned Fleet child's identity; it should not be read as stale-value override protection for arbitrary manual launch shells.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description matches the launch-boundary behavior and does not claim stale-value override.
  • Hooks documentation names the two provisioning paths and their durability without overclaiming the shared writer.
  • Linked #15580/#15587 anchors establish the failed receipt and predecessor adapter.

Findings: Pass.

🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: None.
  • [RETROSPECTIVE]: Seat-stable facts belong at the generated process entrypoint; shared signal writers should remain explicit-input and harness-neutral.

🎯 Close-Target Audit

  • Close-targets identified: #15658
  • #15658 is confirmed not epic-labeled.

Findings: Pass.

📑 Contract Completeness Audit

  • #15658 contains the five-row Contract Ledger.
  • Generator, manual example, adapter, unchanged writer, documentation, and receipt boundary match it without drift.

Findings: Pass.

🪜 Evidence Audit

  • PR body declares L1 for AC1–AC5 and explicitly lists AC6 as residual post-merge validation.
  • AC1–AC5 are covered at the achievable pre-merge ceiling by exact-head unit/static evidence.
  • #15658 labels AC6 post-merge, and the PR's Post-Merge Validation section preserves the exact restarted-seat projection.
  • No L1 evidence is promoted to a live-seat receipt.
  • The unmerged head cannot causally prove the restarted merged-seat behavior; AC6 is therefore correctly deferred.

Findings: Pass. Per the agreed lane contract, a failed AC6 opens a focused follow-up rather than retroactively overclaiming this patch.

N/A Audits — 📡

N/A across listed dimensions: no MCP OpenAPI tool-description surface changes.

🔗 Cross-Skill Integration Audit

  • The predecessor launch/generator convention is documented in learn/agentos/Hooks.md.
  • No startup skill list or MCP-tool reference needs updating.
  • The new convention states where identity is loaded, how generated and manual seats differ, and where diagnostics fire.

Findings: All checks pass — no integration gaps.

🧪 Test-Evidence & Location Audit

  • Execution evidence: every required CI check is green at 8ee95cb9d1f37d0136d1f7d600ad83aafa14f15d; author evidence is current-head appropriate.
  • Reviewer falsifier: the exact two-suite command passed 20/20 in an archive of the PR head; independent TOML parsing accepted all six hook blocks; spawn probes verified missing-value load, inherited-value precedence, and quiet exit 0 on the correctly provisioned command.
  • Test location: generator and Kimi adapter coverage remain in their canonical unit suites.

Findings: Pass.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 99 - Correct process-entry ownership; shared writer purity and ADR-0019 direction preserved.
  • [CONTENT_COMPLETENESS]: 99 - All amended ledger surfaces and AC1–AC5 are covered; AC6 is explicit PMV.
  • [EXECUTION_QUALITY]: 100 - Exact-head CI, focused suites, independent TOML parsing, and env-precedence probes all pass.
  • [PRODUCTIVITY]: 100 - One coherent repair closes the generator, manual-seat, diagnostic, documentation, and regression-test gap.
  • [IMPACT]: 88 - Restores Kimi mid-turn liveness after ordinary seat restarts.
  • [COMPLEXITY]: 42 - Small diff across a lifecycle-sensitive launch boundary.
  • [EFFORT_PROFILE]: Quick Win - Narrow implementation with disproportionate observability value.

Clean exact-head implementation. AC6 is the right post-merge proof, not a pre-merge fiction.
