Summary

  • ocx restart no longer refuses the update path when a service install record exists but no supervisor is running (for example, a launchd plist is installed while its job is not loaded). Both gates now follow supervisor liveness instead of record presence. Ownership claims, unreadable state, running supervisors, foreground parents, shared/client runtimes, and fenced trees still refuse, and nothing stops before eligibility passes.
  • reconcileJournal no longer prints a did-not-shut-down-cleanly warning when a stale journal needed no rewrite (artifacts already original). Journal cleanup on complete restore is unchanged.

Verification

  • bun run typecheck — clean.
  • Focused suites: cli-update-restart + cli-update-restart-home — 39 pass / 0 fail (new: supervisor-liveness truth table; stale-record snapshot accepted).
  • codex-journal suite — 36 pass / 0 fail (new: silent no-op reconcile removes the journal without warning).
  • Related suites (restart-child, restart-transport, system-restart-client, restart-health) — 85 pass / 0 fail; structure:check passed.
  • Full-suite exception: bun run test was not run locally. The change is narrow, so broader validation is left to CI.
  • Live evidence (macOS, plist installed but job not loaded): before the fix, ocx restart with a newer CLI refused; after the fix, the update path completed end to end and the in-place path replaced the proxy PID, verified via healthz.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed (structure invariant synced; no user-facing doc changes required).
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults (attestation, lease, and target rechecks untouched; probe failure fails closed).

Review readiness checklist

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:

  • Required local validation passed; commands, results, and any full-suite exception are documented.

  • I pushed my PR to a recent dev commit (at most 10 behind; a maintainer may still ask for the exact tip before merge).

  • I resolved all correct Codex and CodeRabbit findings.

  • My PR is ready for review.

Summary by CodeRabbit

  • Bug Fixes
    • Standalone update restarts are no longer blocked solely because a service manager is installed but stopped. Restarts remain blocked when a supervisor is running or its status cannot be determined.
    • Recovery no longer reports an unclean shutdown when the saved configuration already matches its original state.

Autopilot verification (head 7c60bf9, 2026-10-06 10:25:10): typecheck + bun test tests/cli/cli-update-restart.test.ts tests/cli/cli-update-restart-home.test.ts tests/codex-integration/codex-journal.test.ts green; change scope 7 file(s); full suite not run locally, remaining coverage left to CI.

📝 Walkthrough

Walkthrough

The standalone update-restart path now permits unclaimed homes with known service state when no service supervisor is running. Journal restoration reports whether it rewrote config or profile artifacts, and reconciliation uses those results when reporting recovery.

Changes

Standalone update-restart eligibility

Layer / File(s) Summary
Unclaimed home snapshot eligibility
src/cli/update-restart-home.ts, tests/cli/cli-update-restart-home.test.ts
Home snapshot reads reject ownership claims and unknown service state instead of requiring the service state to be none. A test verifies that an unclaimed service-state record passes snapshot validation.
Service supervision restart gate
src/cli/update-restart.ts, tests/cli/cli-update-restart.test.ts, structure/runtime.md
Restart eligibility blocks an installed, running supervisor and blocks if diagnosis throws. An installed but stopped supervisor does not block restart. The runtime description and tests reflect this behavior.

Journal restoration and reconciliation

Layer / File(s) Summary
Restore rewrite status
src/codex/journal.ts
RestoreJournalResult adds flags for config and profile rewrites. Restore sets each flag when it writes or removes the corresponding artifact; result paths that do not rewrite artifacts set both flags to false.
Reconciliation warning and result
src/codex/journal.ts, tests/codex-integration/codex-journal.test.ts
Reconciliation now bases its warning and return value on whether config or profile bytes were rewritten. A test verifies that an already-original config remains unchanged, the journal is removed, and no unclean-shutdown warning is emitted.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to fbfe9

Merge is possible with bounded follow-up, but incomplete journal recovery can go unreported, and the new regression test can fail when its chosen PID is live.

Security Architecture Review

Security architecture risk: 🔵 Low · up to fbfe9

Restart remains restricted to verified standalone processes. A narrow recovery-reporting regression can hide failed cleanup of a generated configuration file. Retained recovery evidence and explicit restoration checks limit the impact; no authentication bypass or credential disclosure was established.

Retained concerns

  • Low · reliability · observed: Reconciliation conflates “nothing was rewritten” with “nothing remains to recover.” If config is already original but generated-profile removal fails with a non-ENOENT error, complete remains false and the profile and journal remain, yet both reconciliation branches return without warning. The base emitted a recovery warning in this state. Startup callers ignore the boolean result, so incomplete rollback loses its notification signal. Journal retention still permits later retry; no credential disclosure or automatic activation of the residual profile was established.
Security review details

Security Blast Radius

  • inferred — The observed authority remains bounded to the captured proxy target and selected physical configuration and Codex homes. The compared changes widen eligibility for inactive, unowned service records, not the target-selection or administrative authority used to stop and replace a process. No cross-tenant or privileged service-management expansion was established.

Security Findings and Attack Paths

  • observed — The supplied security assessment retains no findings. Its suppressed supervision candidate is contradicted by the separate manager guard: although Linux diagnosis maps activity-probe errors to false, the later guard maps unreadable or unverified manager state to unknown, and standalone admission accepts only absent.

Trust Boundaries and Controls

  • observed — Restart still requires a configured administrative token before invoking the attested stop transport. Captured runtime PID, port, hostname, secret, and sibling status are rechecked. Ownership claims, unknown service state, and changed physical-home identity or revision refuse the transition.
  • observed — Journal reconciliation preserves active matching-client ownership and live process ownership, including permission-denied process probes. Home ownership is checked before replay, and hash uncertainty preserves artifacts and recovery evidence rather than granting overwrite authority.

Resilience and Maintainability Implications

  • observed — Incomplete profile cleanup retains the journal for retry. Explicit disconnect refuses partial restoration, and native restore reports profileRestoreFailed. These controls limit the new silent-reporting condition to reconciliation callers; they do not make incomplete cleanup successful.

Hardening Proposals

  • proposed — Reserve silent no-op recovery for complete restoration with no rewrites, and represent incomplete cleanup separately so startup retains a failure signal without restoring noisy successful-recovery warnings.

Report incomplete journal recovery before the no-rewrite return.

When the config is already original and profile removal fails, restoreJournalState() leaves the generated profile and journal in place with complete false and both rewrite flags false. Both reconciliation branches then return without warning. Keep the silent return for successful no-op cleanup, but report incomplete recovery first.

🐛 Suggested fix
     if (restored.unverified) {
       console.error("⚠️ Codex journal recovery was not verified; current configuration files and the journal were preserved.");
       return false;
     }
+    if (!restored.complete) {
+      console.error("⚠️ Codex journal recovery was incomplete; check the Codex files and journal.");
+      return false;
+    }
     if (!restored.configRewritten && !restored.profileRewritten) return false;

Apply this check in both reconciliation branches.

Make the dead-owner PID deterministic.

If PID 999999 is live, reconcileJournal() returns before removing the journal, so the removal assertion can fail. Stub the liveness check for this fixture.

🐛 Suggested fix
       const { reconcileJournal } = require("./src/codex/journal");
+      const originalKill = process.kill;
+      process.kill = (pid, signal) => {
+        if (pid === 999999 && signal === 0) {
+          const error = Object.assign(new Error("fixture process is not running"), { code: "ESRCH" });
+          throw error;
+        }
+        return originalKill.call(process, pid, signal);
+      };
       const result = reconcileJournal();
