Part of #451.

What's here

Main moved while we slept: the 0.2.4 release bumped the vendored fork pin twice (amicode.13amicode.14). This absorbs it properly:

  • All 71 golden fixtures re-recorded against v1.18.10-amicode.14 — the diff against the .11 recordings shows zero behavioral drift on the amicode route surface (every body diff is sandbox path / wall-clock stamp noise, all replay-normalized). The about-you description commit turned out to be widget-side rendering only — the profile route shape is unchanged.
  • Both documented post-pin divergences re-verified as standing on .14: the /amicode/connections/auth route still serves the SPA catch-all (probed the new binary directly), and google's auth_methods is still ['browser'] only. The port follows current fork source; normalizations + unit tests unchanged.
  • Self-tracking pin assertion: the contract test now reads opencode.lock.json instead of a hardcoded tag — a future pin bump without a fixture re-record fails loudly (recorded parity claim is stale) instead of silently testing the previous binary's behavior forever.
  • Recorder hardening: every recorder fetch now carries a timeout (5s health poll, 20s requests). Found the hard way — a recording hung indefinitely under machine load because a hanging fetch neither resolves nor rejects, so the poll's catch never fired.

Verification

Contract suite 74/74 (against the .14 goldens); full suite 1196/1196; typecheck clean.

Summary by CodeRabbit

  • Bug Fixes

    • Added timeout handling for health checks and route requests, helping prevent stalled recording operations.
    • Preserved existing retry and failure behavior when requests time out.
  • Tests

    • Updated contract validation to use the recorded fixture version rather than a fixed version.
    • Refreshed Amicode test fixtures and connection snapshots to reflect current recorded results.

…ens, self-tracking pin assertion

Main bumped the vendored fork twice (.13/.14, 0.2.4 release). Re-recorded
all 71 golden entries against the new binary: ZERO behavioral drift on
the amicode route surface (the 13 body diffs are sandbox paths and
wall-clock stamps, all replay-normalized; the about-you description
commit was widget-side only). Both documented post-pin divergences
STAND on .14 (auth route still serves the SPA; google auth_methods
still browser-only) — normalizations + unit tests unchanged, comments
updated.

The contract test's pin assertion now reads opencode.lock.json instead
of a hardcoded tag: a future pin bump without a re-record fails loudly
('recorded parity claim is stale') instead of silently testing the old
binary's behavior.

Also hardens the recorder: every fetch now carries a timeout (health
poll 5s, requests 20s) — an earlier recording hung indefinitely when a
boot wedged under machine load because a hanging fetch neither resolves
nor rejects, so the catch never fired.

Contract suite 74/74; full suite 1196/1196; typecheck clean.

Review Change Stack

📝 Walkthrough

Walkthrough

The recording script now applies per-request timeouts. The contract test tracks the current fork pin from the lockfile. The golden fixture contains refreshed metadata, paths, timestamps, durations, and connection state.

Changes

Amicode fixture refresh

Layer / File(s) Summary
Bound fixture recording requests
packages/extension/scripts/record_amicode_fixtures.mjs
Health probes now time out after 5 seconds. Fixture requests now time out after 20 seconds.
Track fixture provenance and fork pin
packages/extension/test/amicode_service_contract.test.ts
The contract test documents recording-time provenance and compares meta.fork.tag with the current lockfile tag.
Refresh recorded fixture snapshots
packages/extension/test/fixtures/amicode/golden.json
The fixture updates sandbox paths, metadata, timestamps, run durations, and connection state.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 73bd7

The PR improves recording reliability, but timeout paths can still leave temporary resources behind and allow health checks to run far longer than intended, causing leaked processes or delayed test runs. These bounded test-infrastructure risks should be fixed or explicitly accepted before merging.

Bound the complete health poll to 30 seconds.

AbortSignal.timeout(5_000) bounds each fetch, not the complete loop. If every probe times out, the loop can wait about 330 seconds, although the error says within 30s. Use a shared deadline for the fetches and retry delays.

Suggested deadline pattern
+  const deadline = Date.now() + 30_000;
-  for (let i = 0; i < 60 && !up; i++) {
+  for (let i = 0; i < 60 && !up && Date.now() < deadline; i++) {
+    const remaining = deadline - Date.now();
     try {
-      const r = await fetch(base + "/", { headers: { Authorization: auth }, signal: AbortSignal.timeout(5_000) });
+      const r = await fetch(base + "/", {
+        headers: { Authorization: auth },
+        signal: AbortSignal.timeout(Math.min(5_000, remaining)),
+      });

Clean up the fork process and sandbox when a request times out.

When a recorded request exceeds 20 seconds, the fetch rejects and control skips the cleanup at Lines 369-393. This can leave the fork server running and the temporary sandbox on disk. Move child termination and sandbox removal into a finally block that covers the health and recording lifecycle.
