…ng zero budget Reimplements #3039 (author @ntdatt812), whose diagnosis and production logic are both right. confirmServiceServing had a fixed 20s deadline and returned as soon as the clock passed it. A Windows cold start does NTFS ACL hardening and previous- session journal recovery before the listener exists, so #3009 recorded a service that bound a few seconds late and then stayed healthy -- reported as a terminal failure with exit 1. The caller's fallback is to start a second proxy against a port that is about to be taken, which is worse than waiting. Windows now gets 45s, every other platform keeps 20s, and the loop knocks once more after a short grace before calling it dead. Two changes to #3039 as submitted: - It relaxed `expect(probes).toBe(1)` to `toBeGreaterThanOrEqual(1)` in the zero-budget test. That assertion is what stops a future change from sleeping when the caller asked not to wait, and "at least one" passes against exactly the version it is meant to forbid. The `waited` guard already preserves the contract, so the original assertion is restored and the comment says why. - Its Windows-budget test asserted only `toBeGreaterThan(linux)`, which accepts 21s. The reported service bound past 20s, so the number is the contract: the test now pins 45_000 absolutely. Mutation-checked, both restored afterwards: remove the `waited` guard -> 181 pass / 1 fail, the zero-budget test remove the grace probe -> 181 pass / 1 fail, the #3009 test Closes #3009.

Windows Task Scheduler checks now use SIDs with narrow non-ASCII path substitution tolerance. Windows service repair now uses a 150-second child-process timeout. ChangesWindows service lifecycle
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR improves Windows startup recovery and scheduler identity safety, but a custom service-runner integration that fails to report a timeout could start a competing proxy while scheduler ownership is uncertain. The change is otherwise mergeable with explicit owner awareness or follow-up to make timeout reporting mandatory. Sequence Diagram(s)sequenceDiagram

…path Reimplements #3067 (author @ntdatt812). The diagnosis is right and the relocation is right: schtasks converts its XML through the console code page before the bytes exist, so runFile reading as a buffer cannot help. A profile named outside that page comes back as C:\Users\???\... and the exact comparison rejected a registration this process had just created correctly, so `ocx service install` rolled it back (#3064). The remedy needed narrowing. #3067 compiles every unrepresentable run to `[^\\/]*`, which forbids a path separator but allows arbitrary ASCII. A segment that is ENTIRELY non-ASCII then has no anchors left, so C:\Users\<CJK>\.opencodex\service-launcher.vbs matches C:\Users\Admin\.opencodex\service-launcher.vbs and this process would adopt, repair, or delete another account's task. The same hole applies to <UserId>, where MACHINE\<CJK> would match MACHINE\Admin. Its tests use "Người", whose surviving Ng and i letters hide the case. Here an unrepresentable run may match only a run of substitution characters -- '?' per character, U+FFFD, or nothing -- and every ASCII segment, including every separator, is matched literally. A foreign account's path fails because "admin" is not a run of substitutions. Mutation-checked: widening the class back to `[^\\/]*` gives 186 pass / 1 fail, exactly "rejects another account's path that is merely the same shape". Closes #3064.

Approved on exact head 4f691cddc252a13c5bea73cb9f5fbb1b5728521a for the service and scheduler ownership logic.
The recut closes the earlier correctness boundaries without reopening them:
- the Windows 45-second budget and post-deadline grace preserve the exact zero-budget single-probe contract;
- lossy scheduler comparison is limited to
?, U+FFFD, or omission in non-ASCII runs, never arbitrary ASCII or a separator; - trigger ownership is exact and SID-first, while a pre-SID registration is accepted only through the exact legacy account name and is migrated to the SID during repair;
- newly written definitions retain the install-attempt nonce, and unreadable, foreign, ambiguous, or concurrently replaced registrations fail closed;
- the GUI update worker gives Windows repair enough time, but a repair timeout is treated as ambiguous Task Scheduler state and cannot fall through to a competing foreground proxy.
The hosted service, Windows scheduler, all four test shards, keyring, and npm-global jobs passed on this SHA. The macOS job failed in the unrelated tests/server-auth.test.ts:2288 WebSocket token-refresh assertion, not in a changed path; it still means the exact head is not mergeable. This branch is now 22 commits behind dev. Rebase after the 2.40.0 dev-version bump, rerun the complete exact-head matrix, and merge only if every required check is green.

Summary
Reimplements #3039 (author @ntdatt812), whose diagnosis and production logic are both right. Closes #3009.
confirmServiceServinghad a fixed 20s deadline and returned as soon as the clock passed it. A Windows cold start does NTFS ACL hardening and previous-session journal recovery before the listener exists, so #3009 recorded a service that bound a few seconds late and then stayed healthy — reported as a terminal failure with exit 1. The caller's fallback is to start a second proxy against a port that is about to be taken, which is worse than waiting.Windows now gets 45s, every other platform keeps 20s, and the loop knocks once more after a short grace before calling it dead.
What changed from #3039
The zero-budget assertion is restored. #3039 relaxed
expect(probes).toBe(1)totoBeGreaterThanOrEqual(1). That assertion is what stops a future change from sleeping when the caller explicitly asked not to wait, and "at least one" passes against exactly the version it exists to forbid. Thewaitedguard already preserves the contract, so nothing needed relaxing.The Windows budget is pinned absolutely. #3039 asserted only
serviceInstallHealthMs("win32") > serviceInstallHealthMs("linux"), which accepts 21s. The reported service bound past 20s, so the number is the contract, not the inequality.Verification
Mutation-checked, both restored afterwards:
waitedguardprobes at least once even with a zero budgetaccepts a service that binds during the grace after the deadlineThe two mutations fail different tests, which is the point: the grace probe and the zero-budget contract are independent, and #3039's relaxation would have let the first mutation pass.
still fails a service that never bindsis the control — the grace does not turn a dead service into a live one.Checklist
