model-metadata-sync skipped its entire drift gate when scripts/model-metadata.source.json was absent. That snapshot is tracked in this repository, so an absent input is a broken checkout, not an environment variation, and the skip silently removed the only check that the committed src/generated/model-metadata.ts still matches its source. The precondition is now asserted. server-startup-reconcile-resilience probed Bun.serve and skipped four startup cases whenever the probe failed. That is right in a sandboxed agent environment that denies Bun.serve outright, and wrong in hosted CI, where a runner that cannot bind loopback is a broken runner and four assertions disappeared with no trace. The probe now suppresses cases only outside CI, and a CI-only guard case asserts the bind capability so a genuinely unbindable runner names itself.
…nd macOS Four Worker-spawning cases were skipped everywhere except win32. The stated cause was real: Bun 1.3.14 segfaulted at 0xFFFFFFFFFFFFFFF8 mid-file with a balanced workers_spawned/workers_terminated count (exit 133 on macOS Silicon in run 30691129351, exit 132 on ubuntu GHA in run 30700011812), which is a runtime defect our JavaScript teardown cannot close. Bun 1.4.0, the version this repository pins, contains the upstream fix: worker threads are parent-owned and joined before the parent VM is destroyed, bun:sqlite and other native resources are torn down before JSC, and a termination gate keeps native callbacks out of a stopping worker (oven-sh/bun#37075, #38299). oven-sh/bun#38519 reproduces this exact class and records 3/3 crashes on 1.3.14 against 3 x 400 clean terminate cycles on 1.4.0. The skip is deleted rather than re-scoped, and the churn count is a single 8 on every platform: the one-cycle macOS and two-cycle Linux caps were crash avoidance, and a one-cycle 'repeated spawn/reset' case does not test what its name claims. The meta-test that pinned those per-platform caps goes with them. The OS-join settle in src/storage/worker-lifecycle.ts is unchanged.
… the restore-busy case tests/codex-integration/codex-composed-acceptance.test.ts declared the restore-busy envelope a platform-independent contract and then skipped it on win32. The comment was right and the skip was wrong. Run 32344670867 shows what actually happened: 'CLI watchdog: ocx restore --json' at 45197 ms on a shard where neighbouring cases took 54-106 s. No envelope, no SQLite error, no failed assertion - the child was still waiting out production's own busy budget (5 s per attempt, two attempts, 500 ms apart) inside a real CLI process. That wait is not the assertion, so it is shortened rather than budgeted for. In-process history tests already do this with setHistoryDbBusyTimeoutForTests; a child process could not be reached that way, and neither could the history Worker, which is a separate module realm that starts from the provider's default. The run message now carries the parent realm's busy timeout the same way it already carries the homes, validated and refused when malformed, and the Worker adopts it before its first state_5.sqlite open. Production sends the same codex-rs-matching 5 s the Worker would have used on its own, so the happy path is unchanged. The test spawns that one child with a --preload that applies the knob only when OCX_TEST_HISTORY_BUSY_TIMEOUT_MS is set on its environment; no production module reads that variable. The lock, the two-attempt retry, the exit code, the exact JSON envelope, the byte-identity check, the release, and the convergence assertion are untouched.

This adds a new cross-realm history-worker protocol field and changes how the worker configures SQLite before its first database access, but the commit updates none of the architecture documents mapped to src/codex/. The scoped repository instructions require the mapped structure documents to be updated in the same change, so the architecture source of truth currently omits this timeout-propagation invariant; update the applicable structure/ documents alongside the implementation.

Add a lock-contention regression through runCodexHistoryJob.
Line 139 tests the message and calls adoptHistoryDbBusyTimeout directly. The real-Worker test in tests/codex-integration/codex-history-job.test.ts:187-200 runs an unlocked transition with the default database timeout. Its timeoutMs: 1 test at lines 242-255 changes only the outer Worker watchdog. The boundary test at lines 52-60 uses skip, which does not create a Worker.
Add a focused test that sets a non-default parent database timeout, holds state_5.sqlite locked, runs runCodexHistoryJob, and asserts the busy result within an envelope below the default timeout. Without this path, the suite can still pass if history-job.ts omits busyTimeoutMs or if history-worker.ts adopts it after the first database open. The focused regression-test requirement remains unsatisfied.

…each legible (#4851) * ci(windows): restore the margin the six-shard leg lost, and make a breach legible Every Windows dispatch had become a coin flip against the 30-minute job wall. Measured wall time per shard over the last seven lane=all dispatches, in minutes: run 35168946544 30.2 CANCELLED 20.8 20.3 21.3 13.4 21.0 run 35164979005 23.6 22.5 20.4 23.3 13.8 16.6 run 35161399172 23.5 24.7 23.7 26.8 17.2 17.3 run 35152226272 16.5 18.6 20.3 13.7 20.4 24.8 run 35148850553 18.6 20.0 24.8 14.2 23.9 22.8 run 35139132889 21.7 18.8 23.8 18.9 24.7 20.5 run 35134620067 20.5 20.3 19.9 16.8 24.0 28.3 13.4 to 30.2 against a 30-minute ceiling. A shard killed at the wall reports cancelled - neither a pass nor a fail, and with no indication of which file was running when it died. This is the third time this leg has grown into its ceiling; ci.yml already records the first two. One leg reached 30 minutes and died in cleanup, four shards then ran 17-25 minutes with a green 3/4 cancelled at 25m12s, and six were chosen to put each leg at two-thirds of that. Six has now done the same, helped by a suite that keeps growing and by #4835 re-enabling a family that had been skipped. Nine shards, arithmetic in the workflow: total observed work is about 133 minutes, so nine legs project to 26.5 minutes including the ~1.43 slowest-shard skew and the 25% run-to-run variance this file already documents; eight projects to 29.8, which is not margin. The ceiling stays 30 minutes, because raising it is the masking answer and the number is supposed to mean something. The cost is three more concurrent Windows runners and their fixed setup. Cutting work per shard buys time but does not make a wedge readable, so this leg now runs through the same batch runner Linux uses: at-most-12-file processes with a 120-second bound. A timeout or crash fixes the shard red immediately and names the batch; the singleton sweep that follows is diagnosis only and cannot turn it green, exactly as #4837 established. scope=all keeps all 1327 Windows files - Linux alone excludes the storage-policy and api-usage families because separate jobs own them. The aggregate gate counts the nine legs by name through the Actions API. A matrix rolls up to success when a leg never starts, so counting is the only way to know the dispatch produced the evidence it was run to produce. No local suite, focused test, typecheck, build, or install was run. * ci(windows): size the batch bound from Windows data, not Linux's The first attempt gave this leg Linux's batch settings unchanged - 12 files, 120 seconds - and 7 of 9 shards went red on dispatch 35171877721. The runner reported it precisely: "batch 5 timeout failure (exit 124)" followed by "every file passed alone, so the timeout lives in multi-file process state". That second line is the report you get when a bound is simply too small, not when something is wedged. Windows is the slowest hardware on the board, which is the whole reason this leg needed nine shards; a bound copied from the fastest one was never going to hold. Measured across 58 completed batches in that dispatch: median 39.1s, p90 92.6s, p95 100.1s, max 105.8s, and seven batches reached the 120s ceiling. The bound sat at roughly the mean, so about half of all batches were always going to breach it. Six files per batch with a 480-second bound. The sizing case is one naturally slow file: codex-inject-integration.test.ts passes in 312.0s and 317.6s in green runs, so its six-file batch projects to 337.4s, and 421.8s with the 25% run-to-run variance this workflow already documents. 480 leaves 58.2s over that. Six-file attribution halves topped out at 148.0s, so every other batch has an enormous margin. Linux keeps 12 files and 120 seconds. That number is correctly sized for that hardware and sharing one constant across two very different machines is what caused this. The two numbers are independent. Batch size and bound decide how quickly a wedge is named; the nine-shard split decides total wall time. Six-file batches add 12 processes per shard at a measured 0.106-0.168s of wrapper overhead each, about 2.1s per shard, so the margin arithmetic in the shard comment is unchanged. A real wedge now fails within eight minutes naming at most six files, with singleton attribution after the shard is already red. No local suite, focused test, typecheck, build, or install was run. * test(ci): stop the batch oracle from discarding a one-file primary batch The new scope=all case failed expecting three batches and seeing two, and the interesting part is that the runner was right and the test was wrong. batchCalls() classified every invocation beginning with "1|" as singleton attribution. Seven fixture files at batch size three is a valid primary sequence of 3, 3, 1 - so the oracle threw away the last real batch and then reported the count it had just corrupted. A test that miscounts and then asserts its own miscount is the same false confidence this branch has been removing elsewhere, so the fix is the oracle, not the number. It now asserts the exact primary sequence 3, 3, 1, checks the runner's own summary line for seven files in three processes, and still requires the dedicated file to appear. Windows coverage was verified independently rather than assumed, because a scope that silently dropped the dedicated families would be exactly the silent loss this round exists to prevent. From dispatch 35174148018: 1327 test files in the repository, 1320 in general scope, 7 dedicated; the Windows legs ran 148x4 + 147x5 = 1327, and the logs show all seven - tests/server/api-usage.test.ts and the six storage-policy files - executing across shards 3 through 8. That dispatch also carried the calibration result: nine Windows shards, all green, at 10.3 12.2 12.5 13.1 13.6 13.8 15.0 15.1 17.1 minutes against the 30-minute wall, against a six-shard spread of 13.4 to 30.2. No local suite, focused test, typecheck, build, or install was run.

…them (lidge-jun#4835) * test(ci): make two fail-open environment skips hard preconditions in CI model-metadata-sync skipped its entire drift gate when scripts/model-metadata.source.json was absent. That snapshot is tracked in this repository, so an absent input is a broken checkout, not an environment variation, and the skip silently removed the only check that the committed src/generated/model-metadata.ts still matches its source. The precondition is now asserted. server-startup-reconcile-resilience probed Bun.serve and skipped four startup cases whenever the probe failed. That is right in a sandboxed agent environment that denies Bun.serve outright, and wrong in hosted CI, where a runner that cannot bind loopback is a broken runner and four assertions disappeared with no trace. The probe now suppresses cases only outside CI, and a CI-only guard case asserts the bind capability so a genuinely unbindable runner names itself. * test(storage): re-enable the isolate worker-teardown cases on Linux and macOS Four Worker-spawning cases were skipped everywhere except win32. The stated cause was real: Bun 1.3.14 segfaulted at 0xFFFFFFFFFFFFFFF8 mid-file with a balanced workers_spawned/workers_terminated count (exit 133 on macOS Silicon in run 30691129351, exit 132 on ubuntu GHA in run 30700011812), which is a runtime defect our JavaScript teardown cannot close. Bun 1.4.0, the version this repository pins, contains the upstream fix: worker threads are parent-owned and joined before the parent VM is destroyed, bun:sqlite and other native resources are torn down before JSC, and a termination gate keeps native callbacks out of a stopping worker (oven-sh/bun#37075, #38299). oven-sh/bun#38519 reproduces this exact class and records 3/3 crashes on 1.3.14 against 3 x 400 clean terminate cycles on 1.4.0. The skip is deleted rather than re-scoped, and the churn count is a single 8 on every platform: the one-cycle macOS and two-cycle Linux caps were crash avoidance, and a one-cycle 'repeated spawn/reset' case does not test what its name claims. The meta-test that pinned those per-platform caps goes with them. The OS-join settle in src/storage/worker-lifecycle.ts is unchanged. * fix(codex): carry the history busy timeout into the Worker and unskip the restore-busy case tests/codex-integration/codex-composed-acceptance.test.ts declared the restore-busy envelope a platform-independent contract and then skipped it on win32. The comment was right and the skip was wrong. Run 32344670867 shows what actually happened: 'CLI watchdog: ocx restore --json' at 45197 ms on a shard where neighbouring cases took 54-106 s. No envelope, no SQLite error, no failed assertion - the child was still waiting out production's own busy budget (5 s per attempt, two attempts, 500 ms apart) inside a real CLI process. That wait is not the assertion, so it is shortened rather than budgeted for. In-process history tests already do this with setHistoryDbBusyTimeoutForTests; a child process could not be reached that way, and neither could the history Worker, which is a separate module realm that starts from the provider's default. The run message now carries the parent realm's busy timeout the same way it already carries the homes, validated and refused when malformed, and the Worker adopts it before its first state_5.sqlite open. Production sends the same codex-rs-matching 5 s the Worker would have used on its own, so the happy path is unchanged. The test spawns that one child with a --preload that applies the knob only when OCX_TEST_HISTORY_BUSY_TIMEOUT_MS is set on its environment; no production module reads that variable. The lock, the two-attempt retry, the exit code, the exact JSON envelope, the byte-identity check, the release, and the convergence assertion are untouched.

No local suite, focused test, typecheck, build, or install was run. * test(ci): stop the batch oracle from discarding a one-file primary batch The new scope=all case failed expecting three batches and seeing two, and the interesting part is that the runner was right and the test was wrong. batchCalls() classified every invocation beginning with "1|" as singleton attribution. Seven fixture files at batch size three is a valid primary sequence of 3, 3, 1 - so the oracle threw away the last real batch and then reported the count it had just corrupted. A test that miscounts and then asserts its own miscount is the same false confidence this branch has been removing elsewhere, so the fix is the oracle, not the number. It now asserts the exact primary sequence 3, 3, 1, checks the runner's own summary line for seven files in three processes, and still requires the dedicated file to appear. Windows coverage was verified independently rather than assumed, because a scope that silently dropped the dedicated families would be exactly the silent loss this round exists to prevent. From dispatch 35174148018: 1327 test files in the repository, 1320 in general scope, 7 dedicated; the Windows legs ran 148x4 + 147x5 = 1327, and the logs show all seven - tests/server/api-usage.test.ts and the six storage-policy files - executing across shards 3 through 8. That dispatch also carried the calibration result: nine Windows shards, all green, at 10.3 12.2 12.5 13.1 13.6 13.8 15.0 15.1 17.1 minutes against the 30-minute wall, against a six-shard spread of 13.4 to 30.2. No local suite, focused test, typecheck, build, or install was run.

Summary
Two families of tests were disabled to make red go away. Both causes are now fixed and every case runs again.
Storage worker teardown was quarantined off Linux and macOS.
tests/storage/storage-worker-teardown-isolate.test.tsskipped its four Worker-spawning cases everywhere except win32. The reason given was real: Bun 1.3.14 segfaulted at0xFFFFFFFFFFFFFFF8mid-file with a balancedworkers_spawned === workers_terminatedcount — exit 133 on macOS Silicon (run 30691129351) and exit 132 on ubuntu GHA (run 30700011812) — which no JavaScript teardown of ours can prevent. Bun 1.4.0, the version this repository pins, contains the upstream fix: worker threads are parent-owned and joined before the parent VM is destroyed,bun:sqliteand other native resources are torn down before JSC, and a termination gate keeps native callbacks out of a stopping worker (oven-sh/bun#37075, oven-sh/bun#38299). oven-sh/bun#38519 reproduces this exact class and records 3/3 crashes on 1.3.14 against 3 x 400 clean terminate cycles on 1.4.0. The skip is deleted rather than re-scoped, and the churn count is a single8on every platform: the one-cycle macOS and two-cycle Linux caps were crash avoidance, and a one-cycle "repeated spawn/reset" case does not test what its name claims. The meta-test that pinned those per-platform caps goes with them. The OS-join settle insrc/storage/worker-lifecycle.tsis unchanged, because Bun'scloseevent is still not a thread-exit proof.A composed acceptance case declared itself platform-independent and skipped on Windows. Run 32344670867 shows why it was skipped:
CLI watchdog: ocx restore --jsonat 45197 ms, on a shard where neighbouring cases took 54-106 s. There is no envelope, no SQLite error and no failed assertion in that log — the child was still waiting out production's own busy budget (5 s per attempt, two attempts, 500 ms apart) inside a real CLI process. That wait is not the assertion, so it is shortened instead of budgeted for. In-process history tests already shrink it withsetHistoryDbBusyTimeoutForTests; a child process could not be reached that way, and neither could the history Worker, which is a separate module realm that starts from the provider's default. The run message now carries the parent realm's busy timeout exactly as it already carries the homes — validated, and refused when malformed — and the Worker adopts it before its firststate_5.sqliteopen. Production sends the same codex-rs-matching 5 s the Worker would have used on its own, so the happy path is unchanged. The test gives that one child a--preloadthat applies the knob only whenOCX_TEST_HISTORY_BUSY_TIMEOUT_MSis present on its environment; no production module reads that variable. The lock, the two-attempt retry, the exit code, the exact JSON envelope, the byte-identity check, the release and the convergence assertion are all untouched.Two fail-open environment skips became hard preconditions in CI.
model-metadata-syncskipped its entire drift gate whenscripts/model-metadata.source.jsonwas absent, so the only check that the committedsrc/generated/model-metadata.tsstill matches its source could vanish silently. That snapshot is tracked here, so its absence is a broken checkout and is now asserted.server-startup-reconcile-resilienceprobedBun.serveand skipped four startup cases whenever the probe failed. That is correct in a sandboxed agent environment that deniesBun.serveoutright and wrong in hosted CI, where a runner that cannot bind loopback is a broken runner and four assertions disappeared without a trace. The probe now suppresses cases only outside CI, and a CI-only guard case asserts the bind capability so an unbindable runner names itself instead of quietly shrinking the suite.No skip was converted into a widened timeout, a retry, or a weaker assertion, and no budget was raised anywhere in this PR.

Windows shard 5/6 attempt 1 failed a case this PR does not touch:
tests/codex-integration/codex-plugins-doctor.test.ts:370,status --json includes a codexPlugins block and never writes CODEX_HOME, which timed out at exactly its own hand-rolled 20 000 ms budget while itsspawnSyncchild was still starting (Received: null). That same case runs in 2052.10 ms on the same shard ondev(run 35118018849) and 1404.71 ms on attempt 2 here, and the shard's totals matchdev(4105 tests in 1569 s versus 3875 in 1531 s), so nothing in this patch slowed that leg — the only delta this PR makes to that shard is the removal of one instantaneous meta-test. It is the documented Windows child-start contention class: that test's spawn is intrinsic to its assertion but it uses a hand-rolled 20 s instead ofSPAWN_BUDGET_MS(90 s on Windows), which is a separate lane's fix, not a change to sneak in here.Static review covered the call chain from the test preload through
runCodexHistoryJobto the Worker's firstopenStateDb; the argv composition for the added--preloadagainstwithOwnedServiceHomePreload, so each preload stays a separate argv element and a checkout path with spaces is still safe on Windows; the child's environment whitelist, which is why the new variable has to be passed explicitly; the file-size ratchet (no baseline caps cover the touched files, andsrc/codex/history-provider.tsstays under the 2000-line threshold);structure/manifest.json, which binds no invariant to the deleted per-platform cap meta-test; andscripts/test-layout/layout.jsonplustests/fixtures/test-layout-expected.json, which need no entry because no test file was added or moved.The dispatch run's overall conclusion reads
cancelledfor one reason unrelated to any assertion:macos control, the unsharded serial lane, hit its 30-minute wall while still executing tests. It recorded 19 453 passing cases and zero failures before being cut off, including all four re-enabled worker cases, the restore-busy case at 5203.83 ms, the metadata drift gate and the new bind guard. The same lane was cancelled the same way ondev's most recent dispatch (run 35118018849, at the Bun 1.4.0 pin commit2b19983bfd), and it completed in 18-19 minutes on the three dispatches before that, so this is the truncation classci.ymlalready documents for the sharded legs rather than anything this PR introduces. This change adds roughly three seconds to that lane: eight churn cycles instead of one on macOS, against a case that already ran there.Checklist
