…idge-jun#4522) The restart command delegates to the live proxy via POST /api/system/restart. For an unsupervised proxy, the replacement is spawned with selfLaunchArgv(), which reuses the live process's own runtime and entry point. A restart accepted from a different-version CLI therefore respawns the OLD installation while reporting success: the observed 2.49.0 proxy restarted through the 2.53.0 CLI kept /healthz on 2.49.0 with a replacement command line still inside the 2.49.0 package tree. The CLI already learns the proxy's app version from the attested /healthz body, and doctor/status already compare it against the invoking bundle via computeVersionSkew(). Reuse that exact comparison in requestBoundSystemRestart: refuse before POST when the versions differ (either direction), and surface the documented stop/start transaction instead. Placeholder versions (unknown/0.0.0) stay incomparable rather than mismatched, so dev bundles and version-less proxies keep the existing behavior. Server-side enforcement would require extending the restart capability payload with the client version (a v1 contract change) and is left to maintainers; this closes the reported CLI hole without touching the wire contract.

Add an unknown proxy-version case
src/cli/version-skew.ts:14-15 defines both "unknown" and "0.0.0" as placeholders. computeVersionSkew suppresses skew for either value at lines 59-62. The restart client passes the attested body.version unchanged to this helper. The current test covers only "0.0.0" at tests/cli/system-restart-client.test.ts:212, so it would not detect a regression that treats "unknown" as skewed and blocks the POST. Add an "unknown" health-version case and assert that the POST occurs.

…4545) Refuses an in-place restart when the CLI version differs from the running proxy, so a newer CLI no longer hands restart to an older server that then respawns its own binary and reports success.

Fixes #4522
Problem
ocx restartdelegates to the live proxy throughPOST /api/system/restart. For an unsupervised proxy, the replacement is spawned withselfLaunchArgv(), which reuses the live process's ownprocess.execPathandargv[1]. A restart accepted from a different-version CLI therefore respawns the old installation while reporting success:ocx restartinvoked through the 2.53.0 CLI/healthzstill reported 2.49.0 and the replacement command line still referenced the 2.49.0 package treeThis contradicts
restart's documented stop-plus-ensure semantics: a user who just upgraded and runs the newly selectedocx restartexpects the replacement to use that installation.Fix
The invoking CLI already learns the proxy's app version from the attested
/healthzbody, anddoctor/statusalready compare it against the invoking bundle viacomputeVersionSkew()(src/cli/version-skew.ts, introduced for #2701/#3464). This PR reuses that exact comparison inrequestBoundSystemRestartinstead of reimplementing it, so restart enforcement and the existing skew diagnostics can never disagree:restart_version_skewoutcome, andreportRestartFailureprints the documentedocx stop+ocx starttransaction as the workaround.unknown,0.0.0) remain "cannot compare", not mismatch: dev bundles and version-less proxies keep the existing behavior, matching the doctrine already encoded inversion-skew.ts("a false stale-CLI warning would send an operator to reinstall a healthy setup").BoundSystemRestartDepsgains an optionalcliVersionso tests pin both sides explicitly instead of reading the realpackage.json.Deliberate scope
Server-side enforcement would require carrying the client version inside the HMAC capability payload — a
SYSTEM_RESTART_CAPABILITY_VERSIONcontract change (v1→v2) that also affects the tray and any pre-update proxies. That is maintainers' call; this change closes the reported CLI hole without touching the wire contract. Supervised services are unaffected either way: their supervisor respawns from the service definition, which #3464/#2898 already made stable-launcher-based.Testing
