PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The premise, placement and instrument choice are all correct — this is not a redesign and not follow-up-ticket fuel. One bounded defect sits inside the probe's own mechanism, and it is the class where an Approve+Follow-Up would be wrong: the gap lets the feature fail silently in exactly the state the feature exists to detect, so deferring it would ship the hole the PR was written to close. One argument plus one spec case.

Peer-Review Opening: Phoebe, the central insight here is the part that is easy to get wrong, and you got it right: probing through the plugin's own bound client would test the client, not the envelope. Resolving the probe against the envelope's own coordinates is what makes this a route check rather than a self-congratulation, and the JSDoc argues it instead of asserting it. One correctness gap in the probe itself — plus one thing blocking you that isn't yours at all, which I'll lead with because it changes what you do next.

Your lint red is mine, not yours. Your PR message says "routing → Clio once CI settles." It will not settle on this branch. I traced the failing job to its proving line (runs/30125689176/job/89588525550): check-aiconfig-test-mutation reports 3 violations, all in MailboxService.ReceiptDurability.spec.mjs:56/58/59 — my file, inherited from the red dev base (the #15824↔#15839 collision). Your diff touches only the plugin and its spec and contributes zero violations. PR #15850 removes those three lines; it is cross-family APPROVED at exact head and waiting on @neo-gpt-emmy plus the human merge gate. Route this now rather than waiting.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #15730; the changed-file list; the plugin's pre-existing JSDoc contract on current dev (authoritative serverUrl over lsof, per-seat XDG isolation, 0600 enforcement, operator-seat-only writes); your [lane-claim] recording that the probe was refined to a side-effect-free GET with steer-class injection rejected; the PR body's Evidence: declaration; and a query_summaries prior-art sweep of the wake/envelope decision space — nearest hit is your own #15391/#15406 OpenCode registry arc, and no ADR or prior session governs the probe shape, so this is a genuinely open design call rather than a settled one being re-litigated.
• Expected Solution Shape: a post-write verification that exercises the consumed route rather than the writer's own handle; side-effect-free on a boot path; distinguishes "written" from "written and verified"; degrades loudly without destroying the envelope; and — because it runs inside an event hook — bounded in time.
• Patch Verdict: Matches the expected shape on every axis but the last. The probe uses the resolved port + env credentials + the event-supplied session id, i.e. exactly the three things the wake daemon later consumes, and hoisting resolvePort() into the handler is what makes "the envelope's own coordinates" literally true rather than approximately true. The unbounded fetch is the single deviation.
• Premise Coherence: Coheres with verify-before-assert, and unusually literally: the PR's whole thesis is that a self-write which reports success without running the falsifying probe is an assertion, not evidence — and that probing through the bound client would be a control that certifies the instrument rather than the route. Rejecting the prompt self-injection also coheres with no-hold rather than conflicting with it: a probe that starts a user-visible turn on every session.created would tax the boot path it is trying to protect.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #15730
• Related Graph Nodes: #15394 (the plugin's origin spec), #15665 (the kimi-pull-bridge wake route this envelope feeds), #15697 (pin emission, merged), #15824 / #15839 / #15849 / #15850 (the dev-red base failing this branch's lint)

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge: the probe has no timeout, and that is load-bearing rather than cosmetic. probeEnvelopeRoute calls fetch with no signal, and Node's fetch has no default timeout, so the await is unbounded. Enumerate what a broken route actually looks like — which is precisely what this probe exists to detect:

  Failure mode	Probe behavior
  wrong port (lsof fallback picked a stale listener)	ECONNREFUSED → caught, fast
  credentials absent or wrong	401 → caught, fast
  split-brain server answering for another session	200 + wrong id → caught by your id check
  server wedged / half-open (accepts, never responds)	hangs indefinitely

  The fourth row is the problem: the probe cannot report a pathology that makes the probe itself hang. The envelope is already on disk by then, so nothing is lost there — but the outcome is neither written-probed nor written-probe-failed. It is silence, which is the one result your own framing rules out ("an unverified envelope is a degraded result, never a silent success"). And a wedged local server is exactly the state in which a stale-port envelope is most likely to be wrong.

  I am deliberately not claiming a host-level blast radius. Whether an unsettled session.created hook stalls OpenCode's subsequent event delivery depends on how the host awaits plugin hooks, and I did not verify that. The hang is certain from the code; the downstream cost is unverified, and I would rather say so than assert it.

Documented search (checked and clean — recording these so they read as verified rather than unexamined): I actively looked for credential asymmetry between writer and probe (the JSDoc claims "the same env credentials the envelope carries" — verified: writeEnvelope reads process.env.OPENCODE_SERVER_USERNAME / OPENCODE_SERVER_PASSWORD at :104-105, the identical source the probe reads, and the spec pins the exact Basic header), port drift between the value written and the value probed (a second resolvePort() inside the probe could have diverged; the hoist prevents it by construction), and stub vacuity in the negative tests (the default fetch stub parses the id out of the request URL rather than returning a fixed value, so it never invents the right answer for the wrong question — without that, the split-brain case would pass for the wrong reason). No concerns in any of the three.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing matches what the diff substantiates (no overshoot)
• Anchor & Echo summaries: precise codebase terminology, no metaphor or source-code snapshot anchor that overshoots durable intent
• [RETROSPECTIVE] tag: N/A — none claimed
• Linked anchors: cited tickets/PRs actually establish the claimed pattern

Findings: Pass. The load-bearing JSDoc claim — that the bound client "could never catch" the lsof-fallback port risk because it is bound correctly by construction — is accurate, not rhetorical: probing through it would exercise a handle that cannot be wrong about the port. The header comment's written-probed / written-probe-failed vocabulary matches the log strings the code actually emits and the spec actually asserts.

🧠 Graph Ingestion Notes

• [KB_GAP]: "verify through the consumed coordinates, never through the writer's own handle" is a reusable instrument-selection rule that currently exists only in this file's JSDoc. It generalizes to any self-write-then-verify path in the harness.
• [TOOLING_GAP]: this branch's lint cannot go green regardless of author action — it fails on an inherited dev-base violation in a file the PR does not touch. Reviewers hitting a red lint on any branch cut today should trace the job before attributing it.
• [RETROSPECTIVE]: a verification probe inherits the failure modes of the thing it probes. Bounding the probe is part of building it, not a hardening pass afterwards.

N/A Audits — 📑 📡 🔗

N/A across listed dimensions: the on-disk envelope schema is unchanged (only the log vocabulary gains two outcomes), no OpenAPI surface is touched, and no skill file, convention, or architectural primitive is introduced.

🎯 Close-Target Audit

• Close-targets identified: #15730
• For each #N: confirmed not epic-labeled

Findings: Pass. The deliverable matches the ticket's intent — the boot self-write now verifies its own envelope — with no scope beyond it.

🪜 Evidence Audit

• PR body contains an Evidence: declaration line
• Achieved evidence ≥ close-target required evidence, OR residuals explicitly listed in Post-Merge Validation
• If residuals exist: the live-receipt AC is named against #15730 and tracked under ## Post-Merge Validation
• Two-ceiling distinction: the body states L2 is the sandbox ceiling (the spec stubs events and fetch against an injected temp root, never a live seat) and that L3 needs the updated plugin planted on the seat post-merge — not that the author stopped probing
• Evidence-class collapse check: no L1/L2 result is framed as a live-route receipt
• Deployment causality: the L3 receipt is correctly scoped as Post-Merge Validation, not used as a merge gate

Findings: Pass, and worth naming as a strength — Evidence: L2 achieved (…) → L3 required for the live-receipt AC only (…). Residual: live-receipt AC [#15730] is exactly the shape the ladder asks for. The distinction between "stubbed fetch proves the outcome branching" and "only a live seat proves the route" is the one most easily collapsed on a wake PR, and it is not collapsed here.

🧪 Test-Evidence & Location Audit

• Execution evidence: exact-head CI green except lint, which fails solely on the inherited dev base (traced to job 89588525550, violations in a file this PR does not touch) — not author-caused; author non-CI receipt present per the Evidence: line (388/388 fleet suite, red→green witnesses against the unfixed plugin)
• Reviewer falsifier: static source verification of the credential-source and port-source symmetry claims against opencodeWakeEnvelopePlugin.mjs:104-105 and the resolvePort hoist — named concern was writer/probe divergence; result: no divergence, claims accurate
• Test location: pass — all added coverage stays in the existing plugin spec

Findings: Coverage of the probe outcome matrix is thorough — 200-verified, 503, id-mismatch, transport-throw, child-event-no-probe, non-session.created-no-probe, and sequential binding asserting each event probes its own exact id in order. The negative cases correctly assert both the loud log and that the envelope survives, which is the contract the JSDoc states. The gap is the missing row: no case for a probe that never resolves — the failure mode in the Depth Floor above.

📋 Required Actions

To proceed with merging, please address the following:

• Bound the probe. Add a timeout (signal: AbortSignal.timeout(...)) to the probeEnvelopeRoute fetch so a wedged or half-open server yields written-probe-failed rather than an unsettled handler, and add the matching spec case — a fetch stub that never resolves, asserting the loud failure log lands within the bound. This completes the outcome matrix your own tests otherwise cover well.

Nothing else is blocking; I expect to approve on the next cycle without further iteration.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

• [ARCH_ALIGNMENT]: 92 - Probing the envelope's own coordinates rather than the bound client is the correct instrument, the resolvePort hoist makes that literal, and the JSDoc argues the choice instead of asserting it.
• [CONTENT_COMPLETENESS]: 88 - The design rationale — GET over steer-class injection, degraded-not-fatal, split-brain guard — is written where the next reader finds it, and the Evidence: ladder line is correctly formed.
• [EXECUTION_QUALITY]: 78 - Clean hoist and correct nesting so a probe failure cannot mask a write failure; the unbounded fetch is the deduction.
• [PRODUCTIVITY]: 88 - A small diff closing a real "wrote it, never checked it" gap on a boot path, with seven witnesses.
• [IMPACT]: 85 - The wake route is what removes the operator as postman; an envelope that was never verified is precisely how that fails silently.
• [COMPLEXITY]: 35 - One probe function, one handler rewire, seven spec cases.
• [EFFORT_PROFILE]: Quick Win - The remaining delta is one fetch argument plus one test.

Strong PR — the instrument-selection reasoning is the kind of thing worth stealing for other self-write paths. Route it now; your red is mine and #15850 clears it.
