📝 WalkthroughWalkthroughThe CLI update-restart path now admits eligible unclaimed service records when supervision is positively inactive. It fingerprints service records, bounds supervision probes by the transaction deadline, and rechecks admission evidence through parent and child checkpoints.

| 2. **Existing-root validation — FIX.** The config dir must `lstat` as a real directory. A file, a symlink or junction that does not resolve to a directory, or EACCES refuses. | ||
| 3. **D5 contradiction — RESOLVED as admission with a documented limit.** For `source: "standalone"` where the selected executable is exactly `process.execPath` (`bun-runtime.ts:169-170`), the create/remove probe runs in-process; the running process is the selected executable, so the right path policy is exercised. Limitation: there is no child isolation or timeout, and a synchronous filesystem call can block. This is documented in the PR and `structure/runtime.md`. A standalone selection that is not `process.execPath` refuses. | ||
| 4. **Standalone ownership — corrected.** `standalone` describes executable packaging, not Desktop ownership. The L1 note is now only a coordination reminder. | ||
| 5. **Acceptance negatives — ADD.** Tests cover an absent root (refuses, no mutation), a non-directory or dangling root, standalone create/remove failure with cleanup, and standalone identity mismatch (refuses). Non-Windows paths make zero filesystem mutations and zero spawns. Existing behavior stays covered: spawn failure, leftover entries, concurrent nonces, and zero probes for healthy or disabled shims. |

Align the absent-root criteria with the controlling disposition.
The later code-review disposition controls: the preflight creates an absent config root, and a refused probe leaves that empty root in place. The acceptance negative and reflection item 1 still describe the superseded “refuse with no mutation” behavior. Standalone cleanup is a separate case.
Suggested documentation fix

🟡 Minor · Clarify that “absent” applies to launchd service labels, not plist files. · lifecycle.md:135-137

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winClarify that “absent” applies to launchd service labels, not plist files.
The preceding sentence allows an installed but unloaded launchd plist. “Both launchd domains must be absent” can therefore make users think the plist itself must be absent, which conflicts with the supported workflow. The implementation checks that both launchd service labels report absence. Replace “domains” with “service labels” and state the required status.
Suggested fix
-version. An installed but unloaded launchd or inactive systemd service record is eligible only -when it carries no ownership claim. Both launchd domains must be absent; systemd must report +version. An installed but unloaded launchd or inactive systemd service record is eligible only +when it carries no ownership claim.

Under contention a peer's final directory removal can delete the claims directory between the identity check and the link into it. Linux reports ENOENT, which already meant busy; macOS link reports EINVAL, which escaped tryAcquire and crashed the contender. Treat EINVAL as busy when the claims directory is gone or replaced. The contenders test now reports a crashed child's exit and stderr instead of only timing out. Reproduced locally: 3 crashed rounds in 60 before, 0 in 80 after.

Do not treat every lstat failure as proof that the claims directory is gone.
OwnerDeps.lstat uses lstatSync by default, which can fail for permission, I/O, and resource errors. claimDirectoryGone() currently returns true for every failure. If the directory still exists and lstat fails, the EINVAL branch at line 118 can incorrectly report ordinary contention instead of the actual error.
Only treat ENOENT/ENOTDIR, or a changed device/inode, as evidence that the directory is gone.

official Bun 1.4 Bun.spawn ChildProcess exitCode signalCode signal termination documentation
💡 Result:
Bun 1.4’s official docs describe `Bun.spawn()` as returning a **`Subprocess`** (not Node’s `ChildProcess`). The current API reference lists:
- `exitCode`: synchronous exit code, or `null` if the process hasn’t exited.
- `signalCode`: synchronous signal code, or `null` if the process wasn’t terminated by a signal.
- `exited`: a promise that resolves when the process exits.
- `onExit(subprocess, exitCode, signalCode, error?)`: callback invoked on exit, including non-zero exits.
- `kill(signal?)`: sends an exit code or signal to the process. ([bun.sh](https://bun.sh/reference/bun/spawn?utm_source=openai))
So, **check `signalCode` to distinguish signal termination from an ordinary exit**; use `exitCode` for the exit status. The official reference documents these fields, though the page is current documentation rather than a version-pinned Bun 1.4 declaration. Bun’s official 1.4 release announcement is dated August 20, 2026. ([bun.com](https://bun.com/blog/bun-v1.4?utm_source=openai))
Citations:
- 1: https://bun.sh/reference/bun/spawn?utm_source=openai
- 2: https://bun.com/blog/bun-v1.4?utm_source=openai
Check signalCode when detecting a child exit.
Line 139 checks only exitCode. Bun reports signal termination through signalCode, so a signaled contender can be missed when exitCode is null. The test can then wait for the completion deadline instead of reporting the contender's stderr.

Update the child-exit check in the `children.findIndex` callback to treat a
non-null `signalCode` as termination alongside a non-null `exitCode`, while
retaining the missing-result check so signaled contenders are reported promptly.

…s launchers (replaces #6695) (#6812) * fix(service): preflight the selected Bun before baking it into Windows launchers Under a Windows application-control policy the same Bun bytes can write the profile from one path and get EPERM from another. A durable launcher that bakes a denied path crash-loops. Before a Windows service install, repair, or Codex shim install/refresh changes anything, run the already selected runtime itself to create and remove a probe entry in the config directory. On failure refuse with OCX_RUNTIME_PREFLIGHT_FAILED and guidance (reinstall through a permitted npm global install, or select a trusted Bun with OPENCODEX_BUN_PATH). No alternate runtime is discovered or persisted. An orchestrated install admits the runtime once before the existing service is stopped and passes that frozen selection to rendering and the install record. Direct installer calls keep their own admission. The preflight never deletes the config root. Shim auto-restore defers with guidance and startup continues. Other platforms are untouched.

It never deletes it and leaves it empty, so ownership initialization still claims it; assert emptiness instead of absence. Co-authored-by: ismell0992-afk <ismell0992@gmail.com> * fix(service): claim fresh scheduler ownership before runtime preflight Admit the frozen runtime after registration and ownership initialization, before preparation, so fresh installs clear cached ownership refusals and denied probes roll back the new registration. Co-authored-by: ismell0992-afk <ismell0992@gmail.com> * docs(service): document the fresh scheduler preflight order and the published package name A first-time scheduler install registers and claims the config root before the runtime check, and a refusal rolls back that registration. The reinstall guidance now names the published @bitkyc08/opencodex package.

Summary
ocx restarton the update path (a newer CLI replacing a standalone proxy) refused whenever a service install record existed, even when no supervisor ran it. A typical case is a launchd plist that is installed but not loaded. This PR carries the remaining restart-admission half of #6649 and implements the precondition from the maintainer triage on that PR: before the installed-service refusal is relaxed, a full service-record fingerprint must be captured and revalidated through stop and replacement admission.noneno longer blocks the update restart, provided a bounded supervisor probe reportsinactive. Ownership claims, unreadable or unknown state, running or unknown supervisors, foreground parents, client/sibling roles, fenced trees, and Windows still refuse exactly as before.src/cli/update-restart-service-record.ts). Every service-state candidate (authority and mirrors, including absent ones) and the applicable launchd plist or systemd unit are captured. Each file is read without following symlinks, with the descriptor type and identity checked before a bounded read of at most 1 MiB. The digest covers SHA-256 of the bytes plusdev,ino, size,mtimeNs,ctimeNs, mode, and owner. Service state and ownership derive from those same bytes.assertUpdateRestartHomerecaptures the fingerprint and reprobes supervision.runUpdateRestartalready calls it at the initial andbeforeStoprevalidation, after shutdown, immediately before spawn, on every replacement-observation iteration, and before reporting success;runUpdateRestartitself is unchanged. The child receives only the digest (schema 1, 64-character hex) and rechecks it before and under its own lease, and in its existing bind and publication checks. Any drift is terminal: there is no recapture and no second spawn.src/cli/update-restart-supervision.ts). launchd checks both domains, and systemd requiresinactiveplusMainPID=0. Both run with the remaining deadline from trusted absolute manager paths, and each probe receives explicit SSH user-bus environment discovery. The retained PID-bound manager check uses the same bounded runners. An emptyXDG_RUNTIME_DIRnow counts as absent inisSystemd().devlog/_plan/261009_L2-service-journal/, which plans this unit and two related service/config units that will land in separate pull requests.The journal half of #6649 already landed through #6686, so it is not part of this PR.
Interaction with the Desktop-sidecar authority work (#6802 and its follow-up): that lane plans a Desktop veto inside
runUpdateRestart's revalidation. This PR adds no lines there; the only shared hunk is the deps object inrestartFromCurrentInstallation. Whichever lands second adds a combined regression (inactive service record plus same-PID Desktop supervision appearing before the final stop leads to zero stop POSTs and zero spawns) and reconciles the shared structure paragraphs.Co-authored-by: agentHits 140916359+agentHits@users.noreply.github.com
