Implements #311 P6. This PR does not close #311; P7 remains tracked separately in #374.

Summary

  • Proves host-relay retry discipline across real controller process restarts.
  • Rejects non-INSPECT STATUS calls unless they preserve the exact relay lineage identity.
  • Uses the production read-only INSPECT operation before any relaunch.
  • Keeps the change test-only; no production behavior or provider authority code changes.

Review path

  1. tests/fixtures/review-host-relay-restart-worker.mjs runs FINALIZE and INSPECT in fresh Node processes and rejects missing or changed FINALIZE lineage selectors.
  2. tests/review-host-relay-restart-parity.test.ts proves equal reoffers relaunch, drifted or missing reoffers do not, and Process A/C target the candidate view with relay-lineage.
  3. Verify the parent compares provider-returned binding and submission fields before Process C is spawned.

Out of scope: P7 organic refuter/validator coverage remains in #374; P8 was satisfied by the v2.2.0 release, and PR #328 owns maintainer-matrix fixes.

Changes

File Change
tests/fixtures/review-host-relay-restart-worker.mjs Adds the fresh-process controller worker with relay, STATUS, finalize instrumentation, and strict non-INSPECT lineage enforcement.
tests/review-host-relay-restart-parity.test.ts Covers equal, drifted, and missing STATUS reoffers plus Process A/C lineage and candidate-view targeting.

Test plan

  • Restart-parity target: 3 passed
  • Relay suites: 30 passed
  • CI=true pnpm test: 1207 passed, 1 skipped
  • pnpm run test:maintainer: 7 passed, 6 environment-conditioned skips
  • Package verification: 162 files, 64 contract artifacts
  • Native reliability review and pre-commit/pre-push gates passed

Review workload: 398 additions, 0 deletions, below the 400-line budget.

Summary by CodeRabbit

  • Tests
    • Added coverage for provider-relay behavior across isolated process restarts.
    • Verified pending review bindings are consistently reoffered after transport failures.
    • Confirmed changed or missing bindings prevent relay and finalization activity.
    • Ensured failed transport attempts do not trigger automatic retries.
    • Validated successful and failed finalization outcomes, including captured results and errors.

📝 Walkthrough

Walkthrough

Added an isolated worker and restart-parity tests for provider relay capture. The tests verify pending binding preservation across INSPECT and FINALIZE, while rejecting automatic retries, drifted bindings, and missing relay reoffers.

Changes

Provider relay restart parity

Layer / File(s) Summary
Restart worker and process harness
tests/fixtures/review-host-relay-restart-worker.mjs, tests/review-host-relay-restart-parity.test.ts
The worker runs controller modes with queued status responses, stubs relay and native review operations, records activity, and returns JSON results. The test harness runs workers in isolated temporary repositories.
Status and binding fixtures
tests/review-host-relay-restart-parity.test.ts
The tests construct provider bindings, submissions, collect inputs, FINALIZE responses, and INSPECT fixtures.
Restart and drift scenarios
tests/review-host-relay-restart-parity.test.ts
The tests verify exact binding reoffer after transport failure, delayed FINALIZE relaunch, binding drift rejection, and missing-reoffer rejection.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to f4319

This test-only change does not alter production behavior, but its current checks may miss a mismatched relay binding and the harness may hang CI, weakening regression protection and delaying validation. The PR is not merge-ready until these bounded test and timeout issues are fixed or explicitly accepted.

239-262: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Cover drift in every provider-owned binding field.

The negative scenario changes only lens. A retry implementation that ignores submission, captureArgumentTokens, order, or subjectHash can still pass this test. Add table-driven cases that change one field at a time and assert that neither the relay nor native FINALIZE runs.

As per the PR objectives and lib/review-host-relay.ts, Lines 159-167, this suite must verify provider-returned binding and submission fields before relaunch.

Bound the worker process.

Add a finite timeout to execFileSync. Without it, a hung worker blocks the test and prevents t.after cleanup. A timeout raises ETIMEDOUT, which fails the test.

Reviewed: true process-restart parity through fresh module loads, lineage-selector guard on the stubbed provider, INSPECT stays read-only. Approving.
