OpenCode event-stream reconnect budget (fork fix) — replacement PR for #1

Replacement for #1 (same branch, same head, same tree). #1 was closed unmerged because its CI concurrency group ci-1 is wedged by a zombie workflow run (41649525025: jobs cancelled by GitHub at the runner-label-fix push, run record never finalized, still queued); every subsequent CI run for #1 sat pending behind it, closing the PR did not clear it, and no cancel method exists in the estate's gateway catalog. The full diagnosis is filed on #1 (comments 6611666390 and the supersession note).

The fix (from #1, unchanged): the OpenCode adapter's shared-session reconnect gets a real budget — reconnect attempts with backoff instead of failing the shared session on a 15 s openSession timeout, so a brief opencode-server stall no longer kills every live run on the session. Evidence pack: #1 comment 6606250049. Non-author review on #1: APPROVE.

Runner-label repair (also on this branch): ci.yml + mobile-fingerprint-check.yml requested third-party Blacksmith runner labels no runner serves on this fork; swapped to GitHub-hosted equivalents (ubuntu-24.04, macos-26), labels only, non-author reviewer APPROVE (filed on #1).

Armed merge instruction (carried from #1): merge SHA-guarded on head 2f2aecd443225371303f50a87eda4dbb633edd20 the moment the substantive suites (Test Server 1–8, Lint, Changes, Native fingerprint diff) land green on it; then read back the merge commit and main's adapter blob (expect bf82c4e6d42e889c0677b597315ca334aa99561d). Deploy of the staged 0.1.6-mcp2 binary follows under the restart guard per the completion lane's runbook.

ci.yml and mobile-fingerprint-check.yml requested Blacksmith runner labels (blacksmith-*vcpu-*) that no runner serves on this fork, so the PR's substantive suites queued forever while the ubuntu-24.04 workflows completed normally. Swap runs-on to the GitHub-hosted equivalents (ubuntu-24.04 / macos-26). Labels only; no steps changed.

Empty commit (tree unchanged). The previous head's CI run sat in 'pending' with no jobs created after the pre-label-fix run's jobs were cancelled but its run record never finalized, leaving concurrency group ci-1 occupied. This push re-triggers the group on the identical tree.

Walkthrough

CI workflows now use GitHub-hosted runners. The OpenCode adapter retries event-stream reconnections within a five-minute budget, with capped exponential delays and retryable transport failures. Tests cover stalled reconnects and pin the clock for the saved-usage window test.

CI landed — two server shards RED twice; merge chain STOPPED, PR returns to a fork-fix lane

The queue diagnosis and runner-label repair worked: on this PR every suite now starts. The full CI run (41694509565) completed its substantive suites — Changes, Lint, Native fingerprint diff, and Test Server 2, 3, 4, 5, 6, 8 all green, plus Build and Typecheck, Test, Rust, Release Smoke green. But Test Server 1 and Test Server 7 failed (attempt 1: 18:30:49Z->18:33:41Z and 18:30:50Z->18:32:41Z).

Per the stop rule, before filing I ran the one diagnostic re-run available (actions.rerunFailedJobs, run attempt 2, 18:49:47Z). Both shards failed again, faster (Test Server 1: 18:49:52Z->18:52:31Z; Test Server 7: 18:49:51Z->18:51:12Z), and Test Web failed in the re-run set as well (18:49:51Z->18:58:03Z). Passing shards take 4-5.5 min; the failing shards die in 1.4-2.9 min in both attempts. Repeatable, same-shard, short-duration failures are a real red, not a flake.

Failing jobs (attempt 2): Test Server 1 job 126131839347, Test Server 7 job 126131839160, Test Web job 126131839049 — all in run 41694509565. Job log content is not reachable through the estate's gateway catalog (no Actions log-download or check-annotation method exists in it — named coverage gap), so the failing step/test must be read from the job pages in the GitHub UI.

Disposition per SOP-PR-001 and the completion lane's stop rule: the merge does NOT execute, the staged deploy does NOT run, and this PR returns to a fork-fix lane with the failing shards as the spec. Do not fix forward in a completion lane. The fork-fix lane's first question: do shards 1 and 7 (and Test Web) fail on the adapter change itself, or are they pre-existing failures on GitHub-hosted runners (this fork's CI never ran anywhere but Blacksmith before the label repair)? The label commits and the empty re-trigger commit stay on the branch — they are the only reason CI runs at all.

Everything else stands: head 2f2aecd443225371303f50a87eda4dbb633edd20, tree ad788a7d, adapter blob expectation bf82c4e6 unchanged; the staged 0.1.6-mcp2 binary (sha256 3b398777..., CT104 /tmp/t3-mcp2-bin) stays staged for the day the suites land green.

Nitpick Check the reconnect budget boundary before five minutes.

2295-2297: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Check the reconnect budget boundary before five minutes.

The test checks a held turn at two minutes and a failed turn at six minutes. A RECONNECT_BUDGET reduced to about three minutes still passes both checks. Add a held check at 4:59, just before the five-minute budget ends, then assert the failure after it.

Suggested test change
       yield* TestClock.adjust("2 minutes");
       assert.isTrue(Option.isNone(yield* Deferred.poll(seen)));
-      yield* TestClock.adjust("4 minutes");
+      yield* TestClock.adjust("179 seconds");
+      assert.isTrue(Option.isNone(yield* Deferred.poll(seen)));
+      yield* TestClock.adjust("61 seconds");

Hold new turns for the full reconnect budget, or the 30-second cap will fail them.

startTurn waits at most RECONNECT_WAIT (30 seconds) for the stream to reconnect. It then fails the turn with ProviderAdapterEventStreamError. RECONNECT_BUDGET now allows five minutes, so a turn started during a longer outage fails while reconnect is still running. Align the startTurn wait with RECONNECT_BUDGET. Check the rollback and fork path first, because the existing comment says it must not wait on a reconnect.

Stop reconnect retries on authentication failures.

reconnect retries every reconnectOnce failure. Its Effect.retry has a schedule and no predicate, so a rejected server password is retried as well. After a stream loss, borrow reuses the cached connection, which was built with the stored password. If the server rejects that password, the authenticated client.session.active() call in reconcile fails with no catch while turns are running. The failure leaves reconnectOnce, and reconnect repeats it until RECONNECT_BUDGET (5 minutes) expires. Running turns stay pending for that whole period before failAll fails them. The former five-attempt limit ended this retry after a few seconds.

Classify the failure in the retry. Authentication rejections should stop the retry, and transient failures should remain retried. When the retry stops, follow receives the failure through Effect.option and calls failAll without waiting for the budget.

Red shards dispositioned — NOT an adapter regression; CI fully green on head bcc87c09

Local reproduction (estate Code OS drive, lane-red-shards) on byte-exact trees materialized from the refs: base 9b1d351b vs PR head 2f2aecd4 differ in exactly 4 blobs — the adapter (1f2dd94c -> bf82c4e6), its test (37350b49 -> 7410993e), and the two workflow label files. Shards ran with the repo's own tooling (vp test run --shard N/8; the WeightedShardSequencer selection CI's test:cached computes) on both trees, file inventories verified against the git trees (3,223 files under apps/server + apps/web, 0 missing / 0 extra).

Test Server 7 — PRE-EXISTING failure, fixed on this branch. Both trees fail identically: 1 failed | 939 passed | 2 skipped (942 tests, 56 files). The single failure: apps/server/src/usage/UsageService.test.ts > reports saved usage of a removed directory only for windows it reaches — expected the saved 2026-08-01 bucket, got []. Cause: the fixture transcript and its records are pinned to 2026-08-01, while UsageService.readSummary retains saved scan entries only within CACHE_RETENTION_DAYS = 92 days of the real clock (startedAtMs = Clock.currentTimeMillis; a saved entry is served only when mtimeMs >= max(windowStart, now - 92d)). The fixture aged out of retention on 2026-11-01T10:00:00Z; the test has failed on every real-clock machine since, on any runner — this fork's CI had simply never run anywhere before 2026-11-03. It does not touch the adapter's surface: the usage files are byte-identical across this PR, and the adapter's own suite is not in shard 7 (it passes 84/84 on the branch bytes).

Fix (commit bcc87c09, file blob 40bb8560): the one test now runs under it.effect with its service clock pinned to the fixture era (TestClock.setTime(2026-08-05) — the file already imports TestClock, and all time in the path flows through Effect's Clock; no Date.now() in UsageService.ts / usageScanCache.ts). Assertions untouched. The naive alternative (a fresh fixture mtime) was tried and rejected on evidence: it flips the same test's later-window assertion (source status becomes "ok", not "missing") because the saved mtime IS the reach boundary — and any fixed recent date would only re-arm the bomb. Proof: the file is green on both trees (41 passed | 1 skipped); the full shard 7 is green on the branch (56/56 files, rc=0); format clean and lint 0 warnings / 0 errors on the changed file.

Test Server 1 — not reproducible; CI-path-specific. Green locally on BOTH trees (51/51 files; 597 passed | 1 skipped). The adapter suite is not in shard 1 and no shard-1 result differs between trees, so the adapter change is excluded as the cause by direct comparison. What differs on the CI path: shards execute through the test:cached task-cache layer (whose --verify-hits 1 step re-executes one cached task), which local raw vp test run bypasses, and CI pins Node 26.12.1 where local runs used 24.22.1. The exact CI failure line remains with the job logs (the gateway catalog has no Actions log/annotation method — the named coverage gap); it is not needed for the disposition, because the shard is green on the new head (below).

Test Web — cannot be a regression from this PR; green on the new head. apps/web is byte-identical base<->head by tree diff, and the job passed attempt 1 before failing only in the re-run set. Local corroboration is partial (68 web test files green, 0 failed, run stopped early under VM load); the governing evidence is CI itself:

CI on head bcc87c09: every substantive suite SUCCESS — Test Server 1-8, Test Web, Test, Lint, Build and Typecheck, Rust, Release Smoke, Native fingerprint diff, Changes (23 success / 4 skipped at final read; CodeRabbit still in progress and Mobile Native Static Analysis still queued on macos-26 — neither is a failure).

Disposition: MERGE-READY under SOP-PR-001 on head bcc87c09 (adapter blob bf82c4e6 unchanged; the new commit touches one server test file). Per the armed chain this lane does not merge or deploy: SHA-guarded merge -> deploy per the completion lane's runbook under the zero-run restart guard -> stream-health probe -> ed41 re-drive, owned by the T3 serving lane / next drive pass.

Addendum — the exact failing tests from the CI job logs (run 41694509565, attempt 2), folded into the verdict

The sibling log-read has landed; all three failing tests are now named, and each folds into the disposition above without changing it. None touches the adapter's surface (storage cleanup · usage service · web chat view).

1. Test Server 1 — src/storageCleanup.test.ts > "compares the checked-out branch without a full status" (1 failed / 131 passed in the file). Now fully explained: a pre-existing git-build sensitivity in the storage-cleanup branch classifier.

  • The test points a worktree's .git file at a missing gitdir (gitdir: /missing-git-directory) and expects { outcome: "kept", reason: "Repository or branch changed" }; CI got { outcome: "failed", reason: "git: fatal: gitfile does not point to a valid repository: /tmp/storage-cleanup-.../worktrees/feature/.git" }.
  • Mechanism, from the source (src/storageCleanup.ts, branchChanged): its git read() helper classifies an error as repository-changed (return null -> kept) only when stderr contains "not a git repository"; any other stderr becomes a GitCommandError surfaced as git: <first stderr line> — character-for-character the CI outcome.
  • Both endpoints proven: with git 2.43.0 (this VM), the same dangling-gitfile probe yields fatal: not a git repository: /missing-git-directory (exit 128) — the classifier matches, and the targeted test passes on both trees (branch 523 ms, base 831 ms; the full shard also passes on both). The GitHub ubuntu-24.04 runner image generation live at the run (20261026.x) ships git 2.55.0 -> 2.56.0, whose newer diagnostic is fatal: gitfile does not point to a valid repository: ... — Git's own 2.56.0 release notes show this gitfile-diagnosis message is new, still-changing code in that line ("read_gitfile(): simplify NOT_A_REPO error message"; a regression fix in the same diagnosis path). The new wording misses the classifier -> failure path.
  • storageCleanup.ts and its test are byte-identical base<->head (blobs 48154835 / 5f945abd), so the PR cannot be the cause by construction. The shard outcome flips with the git build on the allocated runner (image generations coexist during rollouts), which is consistent with this shard passing on head bcc87c09 with no relevant code change.
  • Disposition: pre-existing fragility, NOT fixed in this PR (production stderr-wording classification in an unrelated subsystem; one problem per PR; this PR's gate is green). Filed as a named follow-on on the Support case: make branchChanged recognize the dangling-gitfile condition structurally (or match both diagnostics) with coverage under both git behaviors. Owner: Support triage -> storage-cleanup maintainers.

2. Test Server 7 — confirmed identical to the diagnosis in the verdict comment: src/usage/UsageService.test.ts > "reports saved usage of a removed directory only for windows it reaches", readSummary(WINDOW) returning buckets: [] at the line-2558 assertion (1 failed / 41 passed in the file). The 92-day retention time bomb and the TestClock fix on this branch stand as filed; shard 7 is green on head bcc87c09.

3. Test Web — src/components/ChatView.browser.test.tsx > "a new draft does not load its reserved thread before the server lists it": a plain 15000 ms test timeout (1 failed / 4944 passed in the suite). The file is byte-identical base<->head (blob 8fe98b78); the job passed attempt 1 and passed on head bcc87c09. Runner-speed timing flake on an unchanged surface — consistent with GitHub-hosted core counts vs the Blacksmith runners this suite's timing was calibrated on. Local note, stated plainly: the partial local web run did not reach this file (only ChatView.logic.test.ts, green), so no local browser result is claimed for it; the governing evidence is the byte-identity plus the CI pass pattern.

Disposition unchanged: MERGE-READY under SOP-PR-001 on head bcc87c09.

Merge. Merged 2026-11-03T20:30:34Z, SHA-guarded on head bcc87c09. Merge commit fa703d647371b80c4ef6a760c49d37c192f0d369. Read-back: packages/provider-opencode/src/server/v2/adapter.ts on main = bf82c4e6d42e889c0677b597315ca334aa99561d (the reviewed fix, byte-exact). Precondition note: the substantive suites were all green on the head; the macOS job (Mobile Native Static Analysis) had been cancelled in a re-run, taking the aggregate Check job with it — re-running the failed set restored the exact merge-ready reading (macOS queued, everything substantive success) before the merge. Filing seam for the gateway lane: a first pulls.merge under the dev-mcp blueprint returned a success-shaped response (merged: true + a sha) with no effect — PR stayed open, content unchanged; the merge only landed under full-authorized. Content read-back caught it; do not trust merge responses under dev-mcp.

Deploy. Server 0.1.6-mcp2 is live on CT104 (t3code-01): service-state.json activeVersion = 0.1.6-mcp2, service active, port 3773 served by versions/0.1.6-mcp2/t3 (sha256 0eebb48da34f73a2b0df9e1eeb6d8a392aa9a7cc0fd2bf57ca5bb079e220e436). Restart executed only in state-DB-verified zero-run windows (watermark + newest-item reads). Two deploy defects found and fixed on the way, both now recorded in pool 05:

  • A hand-copied version dir keeps the old .install-complete content; the launcher requires sentinel content == version string (runtimeExists in serviceLauncher.ts).
  • The child refuses a launcher context whose version differs from the binary's package.json version stamp ("The service launcher started a different t3 version") — the staged binary had to be rebuilt with version 0.1.6-mcp2 stamped (the originally staged sha 3b398777… was therefore superseded, not used).
  • Rollback note: at first start the new server's runtime GC removed the 0.1.6-mcp1 version dir ("Removed unused t3 runtimes"). mcp1 rollback is now rebuild-from-source, not a state flip.

Proof. Stream-health probe post-deploy: thread mcp:26c04924-98cc-44b5-8f90-42071d787c09, first step 21.98 s, 0 errors, no stream losses on the new server's log. First production run on the fixed server: the ed41 re-drive (DeepSeek incumbent leaf) completed a full rebase task — enterprise-docs PR pingdotgg#41 head 17a11f8e, mergeable_state clean, lockfile verified by content read-back.

Correction to the seam claim in comment 6616192509 (lane-final-completion, 2026-11-03)

The saved raw outputs of both merge calls (file timestamps + gateway durations) prove a different mechanism than the one I filed above, and the record is corrected here:

  • Two pulls.merge calls were issued for this PR: first under the dev-mcp blueprint, then — because the first call sat in gateway latency and my read-backs (correctly, at that moment) showed the PR still open — a second under full-authorized.
  • The full-authorized call landed the merge: GitHub merged_at = 2026-11-03T20:30:34Z; its raw output file was written 20:30:35Z (gateway duration 2.9 s).
  • The dev-mcp call executed ~16 s later (raw output written 20:30:50Z, gateway duration 317 ms) and returned the already-existing merge (fa703d64, merged: true). Through this gateway, a merge call against an already-merged PR returns success naming the existing merge commit rather than an error.
  • There was no stale-read defect and no observed dev-mcp success-against-an-unmerged-PR: the read-backs between the calls were accurate when taken. An interim monitor delivery during the lane showed a sha (8584fd6d…) that appears in neither call's saved output; per evidence discipline the saved outputs govern, and that figure is withdrawn.
  • The valid residual caution is narrower and cuts the other way: gateway write latency can leave a first call in flight for minutes — re-issuing the same effect under another blueprint in that window stacks two calls for one effect. Verify by read-back, allow for in-flight latency, and do not stack effect calls.

The merge itself is unaffected: one merge, commit fa703d64, adapter blob bf82c4e6 on main. The deploy/proof sections of the earlier comment stand as filed.
