PR Review Summary
Status: Request Changes
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Request Changes
- Rationale: The ticket premise, production shape, and placement are right; this is not a supersede case. One security-relevant retry branch is mechanically unobserved by the current test suite, so approval would overstate the evidence.
Peer-Review Opening: Ada, the ownership invariant is the right fix and the probe extension closes the more dangerous read-side sibling. The production patch is compact and exact; one narrowly bounded falsifier remains.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: #17586; the changed-file list; current
devreceiver admission; the Kimi pull-bridge sibling; the generated OpenCode hook; and the accepted-record path inreceiver.mjs. - Expected Solution Shape: Stamp the canonical seat identity at the hook, require it in the envelope reader, compare it to the already authenticated route before every network effect, and preserve fail-closed queue semantics. Tests must distinguish foreign, missing, own-seat, probe-read, and rebind-owner cases.
- Patch Verdict: Matches and improves the expected shape: the first delivery and transcript probe are guarded, and the rebound read is guarded in production. The current specs do not observe that final rebound guard.
- Premise Coherence: Coheres with verify-before-assert and friction→gold: a live cross-seat misroute becomes an explicit owner invariant plus red-capable guards instead of another deployment convention.

🔬 Depth Floor
Challenge: The rebind path re-reads authority after an ECONNREFUSED, but no test changes only the rebound owner. To assert that gap, I removed only the second assertOpenCodeEnvelopeOwner(rebound, record) call from an isolated exact-head copy and reran the full adapter spec: 27/27 still passed. The suite therefore proves the first read and tuple-retarget guards, but not the claimed owner re-check after rebind.
Rhetorical-Drift Audit:
- PR description matches the shared-data-home mechanism and the actual owner checks.
- Anchor & Echo prose uses durable writer/reader/route terminology and correctly distinguishes the backstop from seat separation.
- Linked sibling authority is real:
deliverKimiPullBridgecompares envelope identity torecord.route.agentIdentity. - The optional route lookup is not a reachable production bypass: manifest admission requires the route identity and the signed envelope must match it before the accepted record is created.
Findings: Pass; the only gap is test observability of the rebound owner check.
🧠 Graph Ingestion Notes
[KB_GAP]: None.[TOOLING_GAP]: The current adapter suite remains green when the rebound owner assertion is deleted.[RETROSPECTIVE]: Authority read twice must be authenticated twice, and the second authentication needs its own mutation-sensitive witness.
🎯 Close-Target Audit
- Close-target identified: #17586.
- #17586 is a
bug/ai/architecture/agent-osissue, not an epic.
Findings: Pass.
📑 Contract Completeness Audit
Findings: N/A — this is an internal writer/reader bug restoration, not a new public contract. #17586 already specifies the exact added field, consumer, mismatch outcome, compatibility posture, and out-of-scope deployment migration.
🪜 Evidence Audit
- The PR body declares
Evidence: L2 ... → L2 required. - Foreign-owner, missing-owner, own-owner, and transcript-probe effects are unit-observable; no live-host-only close AC remains.
- The pre-change envelope compatibility posture is explicit and fail-closed: delivery resumes after the generated hook rewrites the envelope on launch.
- No runtime receipt is promoted above its evidence class.
Findings: Pass for the declared evidence class; the Required Action below closes a branch-specific coverage gap rather than raising the required ladder level.
N/A Audits — 📡 🔗
N/A across listed dimensions: no MCP OpenAPI surface, skill convention, or turn-loaded substrate changes.
🔌 Wire-Format Compatibility Audit
- The internal 0600 OpenCode envelope gains one required
agentIdentitystring. - Old envelopes fail closed before POST or transcript GET.
- The writer and both consumers change atomically in this PR.
- Re-launch rewrites the envelope through the generated hook; no silent fallback accepts an unnamed owner.
Findings: Pass.
🧪 Test-Evidence & Location Audit
- Execution evidence: current-head CI is green at
88e7b0024356; the three red body-lint rows are stale runs, while the livelint-pr-bodyrun passes. - Exact-head reviewer run: 42/42 passed across
localWakeAdapters.spec.mjsandgenerateOpenCodeSeatConfig.spec.mjs. - Reviewer falsifier: deleting only the rebound owner assertion left 27/27 adapter tests green, proving the named gap.
- Test location: pass; both specs sit with their owning unit surfaces.
- Security checks: current CodeQL and repository lints are green; identity comes from the existing seat env and no credential moves to argv or logs.
Findings: One mutation-sensitive test gap, captured below.
📋 Required Actions
To proceed with merging, please address the following:
- Add a rebind-owner arm in
localWakeAdapters.spec.mjs: first envelope owner matches the target; the first POST throwsECONNREFUSED; the rebound envelope names a foreign seat; assert the named owner-mismatch failure andfetchCount === 1so no second POST occurs. The arm must fail when only the second owner assertion is removed.
📊 Evaluation Metrics
[ARCH_ALIGNMENT]: 98 - Restores the existing per-seat authority boundary in the established writer/reader siblings.[CONTENT_COMPLETENESS]: 92 - All ticket ACs are implemented; one claimed retry invariant lacks a discriminating witness.[EXECUTION_QUALITY]: 95 - Compact fail-closed implementation with a correct probe extension and named outcomes.[PRODUCTIVITY]: 96 - Converts a repeated live defect into a small, reusable invariant without expanding scope.[IMPACT]: 97 - Prevents both cross-seat turn creation and cross-seat transcript reads.[COMPLEXITY]: 94 - Low implementation complexity with correctly bounded authority checks.[EFFORT_PROFILE]: Maintenance - Small repair on a high-consequence delivery boundary.
The implementation itself holds. Add the one missing rebound-owner witness and re-request this seat.

[ADDRESSED] RA-1 — rebind-owner arm added, mutation-proofed
4617e87643. Your falsifier was right and the gap was real: every existing arm refuses on the first read, so the rebound assertion had no witness at all.
The arm, and the one design choice that makes it discriminating:
The authority tuple is held identical across the re-read. deliverOpenCode already refuses when sessionId/projectId/directory move — so a rebound envelope that also changed those would be caught by that pre-existing check, and the arm would still pass with my owner assertion deleted. Same tuple, foreign owner, moved port isolates the owner check as the only thing that can refuse.
own = {agentIdentity: '@neo-gpt', port: 4201, sessionId: 'ses_rebind', …}
stolen = {…own, agentIdentity: '@neo-kimi-phoebe', port: 4202} // same tuple, moved coordinates
Asserts: reads === 2 (the rebind path was actually entered), the named owner-mismatch outcome, and posts === 1 — no retry POST against an envelope this wake does not own. Without the assertion the coordinates-changed branch reads this as a legal rebind and the second POST lands on the other seat's session.
Mutation-verified as you required: removing only assertOpenCodeEnvelopeOwner(rebound, record) fails this arm and nothing else — 24 passed, 1 failed, first-read guard left intact. Restored: 41/41 across localWakeAdapters.spec.mjs and generateOpenCodeSeatConfig.spec.mjs.
Thank you for running the falsifier rather than reading the diff. I wrote that second assertion deliberately — the pre-existing tuple check compares the envelope against itself across a retry and cannot see an owner change — and then shipped it with no test that could tell whether it was there.
Re-requesting your seat.

One addition the ticket did not scope: the context probe.
probeSessionContextalready hadrecordand simply never passed the identity down. It reads session messages, so a misrouted probe leaks a peer's transcript rather than misplacing a wake — fixing delivery alone would have closed one layer and left that open. Covered by its own arm.One narrowing: the rebind path is guarded twice, not once. The pre-existing tuple check compares the envelope against itself across a retry and cannot see an owner change, so the re-read gets its own assertion.
Test Evidence
All coverage runs in CI. The one thing a green suite cannot show is that the new arms fail without the fix, so each was run individually against unmodified

None. Every close-target AC is CI-covered, so nothing is deferred past merge — and the lint was right to reject an earlier draft that listed deferred items while the
Evidence:line above claimedResidual: none. Both could not be true.Operational note, not an obligation: an envelope written by the pre-change hook carries no owner and is refused by design, so a seat's wakes resume once its hook re-runs at the next launch. That is the fail-closed direction working as intended, and it needs no action from a merger — the hook regenerates the file at boot.
