fix(start): recover a same-host record left by an earlier lifetime of this PID - #8562
A container hub (community image, Kubernetes) went into CrashLoopBackOff with Proxy ownership is unverified; startup refused (#8552). The proxy runs as PID 1 in a container on every start, so a runtime-port.json left by the previous run names PID 1, which is the starting process itself. The startup recheck (observeProxyLiveness) signals that PID, gets an answer from itself, reads an ocx command line, and classifies the owner as unknown. Every restart refused the same way.
After this change, a record that names the starting process's own PID counts as stale only when both conditions hold:
this process has never written ocx.pid or runtime-port.json in its own lifetime, so the writer was an earlier lifetime of the same PID number;
the runtime record carries an ownerScope that matches where this process runs. writeRuntimePort now stamps it, and only on the owner's own record.
On Linux, matching needs the same host name, plus one of two stronger facts:
the same network namespace within the same boot. This covers a container restarted inside its Kubernetes pod, because the pod sandbox owns the namespace. The boot id is required because namespace inode numbers repeat across boots and machines.
the same randomly named writable layer of the overlay mounted at /. This is an upperdir in mountinfo with a 64-hex layer id, as used by Docker's overlay2 driver and by containers/storage (Podman and CRI-O). It covers the same container started again, including after a host reboot, and no other container mounts that layer. Three things are deliberately not used. Sequence-numbered containerd snapshots (snapshots/<N>/fs) repeat on nodes built alike. An overlay host root is shared by every sandbox that uses it. A container id is visible to every container joined to that container's network (--network container:, Compose network_mode: service:).
On other platforms the PID space covers the whole machine, so the host name decides. The scope is stored as digests, never as the host name or ids themselves. If the Linux evidence cannot be read, the scope gets a per-process value that never matches, so the check fails closed.
Before: a container restarted with stale records refused forever. After: a container restarted in place recovers and serves. That covers a Kubernetes container restart in its pod, and the same Docker (overlay2) or Podman container started again, including after a host reboot. Docker's containerd image store numbers its layers, so a restart there still refuses.
These still refuse, with the same message, because an old owner could still be serving the same volume from another network namespace:
a replacement pod (RollingUpdate), a pod after a node reboot, a second container with a fixed hostname (start-first, --uts=host, --network container:), another node, or a root filesystem without a randomly named overlay layer;
a record written by an older version, which has no scope; so the first restart after upgrading onto a stale legacy record refuses;
a PID file with no runtime record, a malformed scope, an endpoint that did not answer definitively, and any other alive ocx PID.
The new docs section (guides/remote-hub, "Restarts after an unclean exit") gives the one-time remedy and recommends one writer per state volume (strategy: Recreate or maxSurge: 0 for a Deployment).
Residual risk, for a shared state volume only, all documented in the guide as unsupported:
Processes that share one network namespace can match on it: host networking, pod sidecars, and WSL distros, which share one VM. There the loopback probe still finds a listening owner, but an owner that is alive and not listening is not caught.
The owner's exit cleanup still removes records by PID alone. This was already true before this PR.
Sandboxes that fake namespace numbers or clone a whole VM (gVisor, restored Firecracker or Kata snapshots).
Non-Linux machines with the same host name that sync one home.
The scope is not part of record validity, so a malformed value cannot hide a live owner from status, stop or liveness. Older readers ignore the extra field; the desktop Rust reader has no deny_unknown_fields.
Follow-up, not in this PR: the ownership mutation lease also treats an alive recorded holder PID as live. Its record carries processInstance, which could prove a same-PID earlier lifetime the same way. #8552 shows no evidence that the lease was involved.
Red then green:tests/server/proxy-liveness-self-pid-record.test.ts (new). It includes a POSIX end-to-end case where sh writes its own $$ into both records and then execs ocx start, which keeps the PID across a new lifetime.
With only src/server/proxy-liveness.ts reverted to dev39fd819: 14 pass / 4 fail on the final head. The three same-place self-record cases stay unknown, and the end-to-end start exits with error: Proxy ownership is unverified; startup refused..
With the fix: 18 pass / 0 fail. The start serves /healthz as that PID and republishes a record with an attestation secret and its owner scope. A second end-to-end case with a scope from elsewhere still exits 1 with the refusal and keeps ocx.pid. Unit cases cover:
a writable-layer match across a reboot;
an equal namespace from another boot;
a same-host record from another namespace and layer;
another host;
legacy, malformed and host-only scopes;
the machine-wide branch;
mountinfo parsing. Docker overlay2 and Podman layer ids count. A joined container's hostname bind mount, non-overlay roots, fuse-overlayfs, containerd's numbered snapshots, and an overlay host root do not.
Focused suites: liveness, start owner, journal order, restart ownership, client link, process state, config, layout, structure, ratchet and remote-hub docs claims gave 789 pass / 0 fail (19 files) on the final revision. The earlier revision's wider set, which also included dispatch and update mutex, gave 899 pass / 0 fail.
Checks:bun run typecheck (2,418 files, no errors), bun run structure:check and bun run privacy:scan pass.
bun run test:changed against dev, run on the first revision: it selected 2,288 files. Result: 52,159 pass / 35 fail / 3 errors. Every failing file also fails on unmodified dev39fd819 in this environment (local-control-socket, codex-cli-update-*, catalog-omit-disabled-native, native-ultrafast-picker, codex-composed-acceptance, update-stop-first). update-sync-mutex passes alone on this branch.
Reviews: a design audit ran in three rounds before implementation. Two security reviews then shaped this revision:
The first found that the host name alone collides in reachable setups.
The second found that a container id is shared through --network container:, so the key is now the root overlay's own layer.
The third found that containerd's numbered snapshots repeat across nodes, so only randomly named layers count.
An independent review asked for the boot id to apply only to the namespace leg, so a Docker container survives a host reboot.
NOT RUN:
full bun run test locally;
test:changed on the final revision (same import graph as the first; focused suites rerun instead);
macOS/Windows (the end-to-end cases are POSIX-only because Windows has no exec handoff; the unit cases run everywhere);
a real Kubernetes pod or Docker daemon. No Docker here, so whether a --read-only container shows upperdir in mountinfo is unverified; if it does not, that container refuses as before.
Checklist
Scope stays focused and avoids unrelated cleanup.

Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. (Service ownership path; separate security review on the final head before merge.)
Summary by CodeRabbit
New Features
Startup can recover stale proxy records after an unclean exit when ownership is verified for the same process environment. Unverified or incomplete ownership still prevents startup.
Documentation
Updated the Docker deployment guide with recovery scenarios, cases where startup remains blocked, and steps for safely resolving unverified ownership.
Documented the ownership checks and constraints involved in recovery.
Runtime records now include an owner scope. Startup recovery skips a same-PID runtime record only when the current process has not published ownership records and its owner scope matches the recorded scope.
Changes: Same-PID ownership recovery
Layer / File(s)
Summary
Runtime record metadata src/config/process-state.ts, tests/service/process-state.test.ts
Process-state writes track whether the process has published ownership records. Runtime records for the current process include an owner scope. Linux scopes can include network-namespace or container identity; non-Linux scopes use platform and hostname. Tests check scope derivation and serialization.
Liveness observation receives the runtime record’s owner scope and a snapshot of current-process ownership. It skips the current PID only when ownership records have not been published and the scopes match.
Recovery validation and guidance tests/server/proxy-liveness-self-pid-record.test.ts, structure/runtime.md, docs-site/src/content/docs/guides/remote-hub.md, scripts/test-layout/layout-start-ownership.json, tests/fixtures/test-layout-expected.json
Tests cover owner-scope matching, same-PID recovery, and refusal when ownership cannot be verified. The documentation describes recovery conditions and operator steps. The test-layout maps register the new server test.

Explanation
The PR addresses the coding requirement in #8552. src/config/process-state.ts adds the lifetime flag, RuntimeOwnerScope, scope derivation, scope comparison, and ownerScope serialization. src/server/proxy-liveness.ts skips a self-PID runtime record only when the current lifetime has not published ownership records and the recorded scope matches the current scope. The implementation fails closed for missing, malformed, foreign, or unavailable scope evidence. It preserves refusal for PID-only records, other live PIDs, published ownership, and inconclusive liveness results. tests/server/proxy-liveness-self-pid-record.test.ts covers the matching and refusal cases, including POSIX startup recovery and retention of the PID file for a foreign scope. The documented Kubernetes same-pod and same-overlay-container recovery path therefore provides safe recovery without removing ownership fencing. The lease follow-up is outside #8552's required coding scope.

Do not use hostname equality as proof that the previous owner exited.
If two PID namespaces share a state directory and hostname, both processes can have the same PID and hostIdentity. The starting process has publishedOwnership === false, regardless of whether the other namespace's proxy remains alive.
When the local endpoint probes return definitive negative results, this expression becomes true. Line 556 then skips the PID candidate and returns absent. src/cli/start-owner-fence.ts, Lines 7-20, consequently permits PID removal and startup-journal reconciliation against state that the other proxy still owns. A later bind or server lease cannot undo that earlier recovery mutation.
The hash distinguishes hostname values, not process namespaces or ownership lifetimes. Retain unknown unless additional evidence establishes exclusion of the previous owner. Add a regression case with a live owner in another namespace that has the same hostname-derived identity and PID.

Value: a container hub can no longer get stuck in CrashLoopBackOff on its own leftover records. Before this change, a container that restarted after an unclean exit could never start again without manual cleanup, because the proxy is always PID 1 and the leftover record named that same PID.
UX change: a container restarted in place now recovers by itself. That covers a Kubernetes container restart inside its pod, and the same Docker (overlay2) or Podman container started again, including after a host reboot. Every case where the old owner might still be serving keeps the existing refusal, with the same message. The remote-hub guide now explains those cases and the one-time remedy.
Regression risk for existing users: low. The new skip applies only to a record that names the starting process's own PID and carries an owner scope this process can match. Desktop, npm-global and service installs on a normal host never start with a record naming their own new PID, except after a reboot reuses the PID. Every other liveness branch is unchanged, and all existing liveness and start-owner suites pass unchanged. Records gain one ownerScope field that older readers ignore. The first restart after upgrading onto a stale legacy record still refuses, and it does so on purpose: the old-version owner may still be alive.
Windows impact: none in practice. Windows uses the machine-wide branch (host name only), its PID space is global, and it has no exec handoff, so a self-PID record there means the previous owner has already died. The end-to-end cases are POSIX-only; the unit cases run on every platform.
Security: this is a service-ownership path, so a separate security review on the final head is required before merge. Three earlier revisions failed that review: the host name alone can collide, a container id is shared through --network container:, and containerd's numbered snapshots repeat across nodes. The current revision requires the same host plus the same network namespace within one boot, or the same randomly named root overlay layer.

Require proof of owner absence before moving ownership records.
If an existing owner is alive but its listener is temporarily down, an operator can confirm that nothing currently serves the directory and still remove both records under this instruction. The next start can then proceed without that persisted ownership evidence. Tell operators to verify the process, home, supervisor, and listener independently. If any result remains uncertain, instruct them to stop rather than move the records. As per path instructions, “Do not edit runtime records or kill processes to work around uncertain ownership; verify process, home, supervisor, and listener independently, and stop if evidence is incomplete.”

Do not use a network match alone to prove the PID owner is gone.
Two containers in one pod can share a network namespace and state directory while each has PID 1. A serving listener is reachable by the probes, but during management restart the first container can remain alive with its records after its listener closes. Definitive negative probes then let the second container skip PID 1, remove its PID record, and potentially reconcile its journal.
Require evidence that excludes a live owner in another PID namespace before recovery. Add a regression test for matching networks and different container IDs.

Gate the integration test on a verifiable Linux scope.
If the Linux runner cannot read a valid boot ID or either stronger scope fact, runtimeOwnerScope() generates a random host digest per process. Line 217 then writes the parent’s digest, while the child computes a different digest and correctly refuses startup. This test fails even though the fail-closed runtime behavior works as designed. Check those scope preconditions before asserting recovery, and cover the refusal fallback separately.

Qualify recovery by the proxy’s recorded PID.
The guide presents the same-container restart as automatic recovery and explains it by saying the proxy is PID 1. The repository’s compose.yaml sets init: true, which runs an init process as PID 1. The recovery exception instead requires the stale record’s PID to equal the new proxy process’s PID. State that condition explicitly; do not describe the supplied Compose proxy as PID 1.

* fix(link): ocx restart recycles a client runtime whose connection was removed, under any owner
After ocx disconnect (or a newer connect) a desktop- or service-owned client runtime refused
ocx restart with restart_supervised and kept answering role client, so a Home-driven leave over
SSH could not finish. A changed connection has nothing to keep: accept the restart and hand off
to the standalone recycle (desktop exit 75, service exit 1, otherwise a spawned replacement).
ocx disconnect now restarts a still-live client runtime itself and exits 1 naming ocx restart
when that does not complete.
* fix(link): name the failed condition and its fix in the Child restart preflight refusal
child_restart_unsupported now carries a hint for each cause (still linked, Hub, stale client
runtime, no restart capability, port mismatch, nothing answering) with the Child command that
fixes it, and the CLI appends the error code.
* fix(link): a client injection takes over the Codex journal so a supervised relaunch keeps routing
ocx connect --link re-injected routing over a standalone proxy's injection but left the journal
owned by that process. After the supervisor relaunch (desktop or service), startup recovery saw
a dead process owner and restored native Codex and the old catalog under the new link.
* fix(cli): point refusal and status hints at commands that work beside a live or desktop-owned proxy
* fix(cli): explain client_catalog_ownership_changed on disconnect and name --keep-catalog
* docs(link): Child leave and re-link behavior under the desktop app or a service
* fix(cli): name the desktop-remote folder that blocks disconnect and how to clear it
A desktop-remote folder holding no state or receipt (seen with a renamed receipt) refused
disconnect with only desktop_lifecycle_unsafe. The inspector now returns that reason and path,
and disconnect names the folder and says to move it aside.
* fix(link): recycle a supervised client only on a proven end of its connection
Review: an invalid or mismatched client state also read as "changed", so a supervised runtime
could exit on an unreadable config. Only a disconnected state or a different committed connection
now counts, and the controller rechecks right before it recycles.
* fix(link): hand the Codex journal to a client only after its connection commits
Review: taking the journal during injection let a runtime starting mid-connect restore native
Codex as uncommitted client routing. The journal now stays its live writer's until
commitClientConnection, then connect (and each connected sync, as the retry) adopts it under the
Codex config lock.
* fix(cli): an inconclusive liveness probe after disconnect fails with guidance
Review: findLiveProxy returns null both for no runtime and for a probe that could not decide, so
disconnect could report success beside a still-serving client runtime. It now reads
observeProxyLiveness and exits 1 on unknown; --orphaned-token skips the restart step.
* fix(link): bind the journal handover to the connection guard and report a failed one
Review round 2: adoption now never takes another client's journal and re-runs the caller's
connection guard under the Codex config lock (connect: same owner, link and token; sync: the
injection's own guard), so a stale sync cannot claim a later connection's journal. A sync whose
handover failed exits 1 and says to sync again.
* fix(link): hold the mutation lock through the journal handover and report every failed one
Review round 3: the connection guard and the journal write now run under the config mutation
lock inside the Codex config lock, so no connection or runtime change lands between them.
adoptJournalForClient returns adopted / owned / missing / foreign; sync treats missing and
foreign as a failed handover, and the machine sync API answers 409 success:false for it.
* fix(link): only another client's journal leaves routing at risk; connect says so
Review round 4: external Codex providers leave no standard journal, so a missing journal is no
longer a failed handover (sync no longer exits 1 for them on every run). Connect now warns when
the journal belongs to an earlier connection, naming 'ocx sync --restart-codex' after the next
restart, and the sync and machine-API messages give the same recovery.
* fix(link): an unreadable journal fails the handover instead of reading as missing
Review round 5: adoption read the journal through readJournal(), which maps both a confirmed
absence and an unreadable journal to null. It now inspects the journal directly: only a confirmed
absence is "missing"; unknown throws, which sync and connect report as a failed handover.
* fix(cli): skip the post-apply runtime restart after a failed journal handover
Final review: ocx sync still restarted a link Child's runtime after reporting a failed handover;
with an earlier connection's journal that restart restores the snapshot over the routing just
applied. The restart is now skipped and the message says so.
* test(link): run Codex-path journal scenarios in a child with an owned CODEX_HOME
Final review P1: three teardown tests wrote and removed config.toml, the journal and the catalog
through paths fixed when src/codex/paths loads. Run from outside the repository (no preload), those
raw writes would land in the real ~/.codex. They now run in tests/fixtures/client-link-journal-
runner.ts, whose CODEX_HOME and OPENCODEX_HOME point into the test's own temp home before any
import; the parent touches no Codex path and removes only that owned home.
* fix(link): a restart-driven recycle exits for a service only when it is viable
Final review: the recycle path called recycleStandalone, which exited 1 whenever OCX_SERVICE=1,
so a process that outlived its service registration went down with nothing to relaunch it. The
controller now passes its supervisor verdict (isServiceViable included) into the recycle; without
a viable service it starts a verified replacement, and the replacement never inherits the marker.
* fix(cli): disconnect restarts only a runtime its own disconnect left behind
Final review: a connect landing between disconnect and its restart could have its new runtime
restarted and the machine reported standalone. Disconnect now rechecks that the durable state is
still disconnected right before the restart, and reports standalone only when the runtime seen
after the restart is not a client.
* test(link): sandbox the Codex catalog path in cli-sync-expect-link before it loads
Coordinator review round 2 P1: the file's shared setup writes and removes DEFAULT_CATALOG_PATH
with raw fs calls; without the repository preload that path resolved into the real Codex home.
A first-import helper now points CODEX_HOME at an owned temp dir before src/codex/paths loads
(and removes only that dir), and the file fails closed at load if the path is still real.
* fix(cli): bind the disconnect restart to the runtime disconnect observed
Coordinator review round 2: the check and the restart were separate discoveries, so a connect
committing in between could have its new runtime restarted. The restart is now sent only to the
observed pid (bindRestartToPid; the client listener admits it only for that pid), and a vanished
runtime gets no generic start.
Also (coordinator review round 2): disconnect claims standalone only for a live non-client
runtime after the restart; an absent or inconclusive observation exits 1 naming ocx status /
ocx restart.
* fix(link): recheck the connection after the supervisor lookup, right before the recycle
Coordinator review round 2: the recheck preceded the asynchronous supervisor lookup. A
deterministic test holding that lookup open while the connection becomes current showed the
gap; the recheck now runs after it.
* test(link): prove every test Codex home is owned by path, not by an inherited flag
Coordinator review round 3 P1: the sandbox helper skipped itself when OCX_TEST_HOME_GUARD=1,
which can be inherited without the preload, so a custom real CODEX_HOME got the sentinel. The
helper now always owns a temp CODEX_HOME when src/codex/paths is not loaded yet, and test files
refuse to load unless the resolved home is that dir or the .codex of a test root whose owner
marker names this process. Applied to cli-sync-expect-link and client-link-teardown; the journal
runner proves its paths inside the parent's temp home; codex-journal children and client-runtime
recycle tests pin OPENCODEX_HOME to owned temp dirs. New tests cover an inherited flag and a
custom CODEX_HOME without the preload.
* fix(cli): bind the disconnect restart to the runtime generation; exit 0 only when disconnected
Coordinator review round 3: a pid can be reused, so disconnect captures the observed runtime's
record (pid, port, per-process attestation secret) and the bound restart attests and derives its
capability from that record; another process at the same pid cannot prove it. Any client state
other than disconnected, read after the observation and again before exit 0, now exits 1 with
its own message, on every branch, so a Home-driven leave stops before its own ocx restart.
* test(link): await the supervisor lookup's entry instead of polling microtasks
* docs(link): structure note for the generation-bound disconnect restart and its exit rule
* fix(cli): keep src/cli/index.ts under the file-size ratchet
CI test 2/5 on b47df93: the restart binding grew src/cli/index.ts to 2003 lines, past the
2000-line threshold. The binding now adds no lines there (1999, as on dev); its description
moved to the handleProxyRestart type in dispatch.ts. Behavior unchanged.
* test(link): the journal runner writes only into a home its parent handed it a token for
Coordinator review round 4 P1: the runner proved only that its paths were under HOME. The parent
now writes a one-time token into the temp home it created and passes it in OCX_FIXTURE_TOKEN; the
runner exits 2 before any import or write unless they match. A new test runs it against a temp
folder standing in for a real home, without and with a forged token, and asserts it untouched.
* fix(cli): after a refused restart, say who answers before advising a restart
Coordinator review round 4 P2: when a client still answered after the bound restart, disconnect
said the old runtime served the old connection and advised ocx restart, which could interrupt a
newer connection. It now re-reads the state and recaptures who answers: a new connection in use,
an unreadable state or a different runtime are reported for inspection, and a plain restart is
advised only while the captured runtime still answers. The absent/unknown branch reads the state too.
* test(link): assert the codex-home-sandbox branch in effect instead of assuming the preload
* docs(link): describe the disconnect state reads per branch
* fix(cli): one recovery-advice function for every exit-1 outcome of the disconnect restart
Coordinator review round 5: the inconclusive-liveness and uncapturable-record exits returned
before reading the client state and advised ocx restart, which could interrupt a connection that
had just landed. Every exit-1 outcome now takes its advice from recoveryAdvice(state read now,
who answers): a plain restart only for the captured runtime under a disconnected state (or a
start when nothing answers); a connected or unreadable state gets ocx status inspection only. A
sweep test checks every exit-1 branch under each non-disconnected state.
* fix(link): a missing config.json is not evidence that the served connection ended
Final review P2: readClientConnectionState() reads a missing config.json as the default
configuration, i.e. disconnected, so the new restart admission could recycle a runtime still
serving from memory. readClientConnectionStateWithEvidence() maps that case to invalid; the
runtime's restart admission and ocx disconnect's state reads use it.
* fix(link): keep a client runtime its service manager owns but cannot be proven to relaunch
Final review P2: a systemd unit started by hand while disabled is not viable, which mapped to no
supervisor, so the recycle detached a replacement inside the unit. classifyClientRestartSupervisor
separates ownership (OCX_SERVICE or OCX_SERVICE_MANAGED) from relaunch (the service diagnostic):
owned but not viable is service-unproven, refused at admission and named in the CLI message; only
an unowned process detaches, and standaloneRecycleEnv clears every supervisor marker. ocx
disconnect advises the service manager when that is what refused.
* docs(link): structure note for restart evidence and service ownership
* fix(link): decide disconnected-state evidence from one valid snapshot of config.json
Final review round 2: the evidence reader still returned disconnected for a saved file that
fails validation, and paired raw data and diagnostics from two reads, so a connect committed
between them could leave old bytes deciding. It now decides from one readConfigFileSnapshot read:
disconnected only for a valid saved file with no client; missing, unreadable, invalid or fallback
is invalid with its reason. Both readers share one classification.
* fix(link): restart ownership needs manager evidence and a loaded job, not a bare flag
Final review round 2: OCX_SERVICE=1 alone is also what ocx claude and ocx opencode give their own
proxies, so their runtimes were refused as service-owned (a regression); and launchd's unknown load
state counted as proof of relaunch. Manager-launched evidence is now isSupervisedServiceChild;
relaunch needs the diagnostic to be viable and running. A bare OCX_SERVICE=1 is a companion when no
service is installed and the new owner-unproven refusal when one is, with advice naming both owners.
claudeProxyStartEnv is extracted (behavior unchanged) so the companion's real environment is tested.
* docs(link): structure note for single-snapshot evidence and manager ownership
* fix(claude): keep the provenance stamp at the ocx claude spawn site
* fix(link): decide client restart ownership from positive evidence only
A bare OCX_SERVICE=1 was read as a companion whenever no unit file existed, but every service registered before v2.49 launches with only that flag, and systemd keeps a running unit in its cgroup after its file is removed. ocx claude, ocx codex and ocx opencode now mark their own proxies (OCX_COMPANION_PROXY); a bare flag without that marker or a manager marker is owner-unproven whatever the unit file says. The detached replacement clears the companion marker too. The single-read test now counts config.json reads at the file system.
* fix(link): give an owner-unproven client runtime advice and steps that end it
Ending an ocx claude or ocx opencode session does not end its detached proxy. ocx restart and ocx sync now name ocx stop then ocx start; sync reports owner-unproven as its own outcome and exits 1 instead of a background-service deferral. ocx disconnect stops that exact runtime itself: it terminates the captured generation only after it attests the captured secret, and starts OpenCodex only once the exit was observed, the state is still disconnected and nothing else answers.
* docs(link): owner evidence, companion marker and owner-unproven recovery
* Revert "docs(link): owner evidence, companion marker and owner-unproven recovery"
This reverts commit 340b067.
* Revert "fix(link): give an owner-unproven client runtime advice and steps that end it"
This reverts commit c4b83b6.
* Revert "fix(link): decide client restart ownership from positive evidence only"
This reverts commit 707b92b.
* fix(link): a bare OCX_SERVICE=1 runtime keeps origin/dev restart, disconnect and sync behaviour
Scope split after final review round 4. The owner-unproven verdict is gone. A runtime whose only supervisor evidence is a bare OCX_SERVICE=1 (a legacy service child or a companion proxy) gets origin/dev decision again (isServiceViable ? service : none, no ended-connection branch); the ended-connection recycle now needs positive ownership evidence (desktop, a manager marker, or no OCX_SERVICE). Such a runtime marks its record restartOwnerUnproven, and ocx disconnect leaves it alone with exit 0, as origin/dev did. Tests pin each command against the merge-base code.
* docs(link): bare OCX_SERVICE=1 runtimes keep their previous restart and disconnect behaviour
* fix(link): disconnect restarts only a runtime whose record states an owner it handles
Final review round 5. A client runtime now records the owner it classified from positive evidence (restartOwner: desktop, service-manager or none). ocx disconnect restarts only a record stating one of those; a bare OCX_SERVICE=1 runtime, a runtime started before this field existed, or an unknown value gets origin/dev disconnect: no restart request, exit 0. Replaces the restartOwnerUnproven mark, which left old runtimes exposed to the new restart.
* docs(link): disconnect restart applies to runtimes started on this version; service-unproven still refuses
* fix(link): client restart ownership reads only current manager markers, never the parent command line
Final review round 6. restartOwnerEvidence and the restart classification used isSupervisedServiceChild, which also accepts a markerless legacy Windows registration from its parent command line. Both now use isMarkedSupervisedServiceChild (OCX_SERVICE_MANAGED or the Windows wrapper marker), so such a runtime records no owner and keeps origin/dev restart, disconnect and sync behaviour.
* docs(link): disconnect advice per observed state; manager evidence is markers only
* fix(link): no supervisor marker reaches a process its supervisor did not launch
Final review round 7. A shell a manager-owned runtime hands to a tool inherits OCX_SERVICE_MANAGED or the Windows wrapper marker, so a companion started from it recorded a service-manager owner that does not own it. One shared list (src/lib/supervisor-markers.ts) now clears every supervisor marker from the three companion launch environments, the standalone recycle, the detached ensure/tray start, the CLI detached start, the restart replacement, the CLI and launcher post-update restarts, the update worker pinned start, and the Cursor background shell and desktop executor.
* docs(link): bare-flag legacy service can detach on the dev path; markers never reach unlaunched processes
* fix(update): clear supervisor markers inline in the update restart bodies
The update restart and pinned-start bodies run under their tests dependency injection, so they delete the shared marker list inline (as bin/ocx.mjs does) instead of calling the helper; the pin test checks the list stays the same.
* test(link): a stale same-PID runtime record never reaches the disconnect restart
Covers the meeting of #8562 (a record left by an earlier lifetime of this PID) with restartOwner: the disconnect step decides from the liveness observation, so such a record is never captured and no restart is requested.

Summary
A container hub (community image, Kubernetes) went into CrashLoopBackOff with
Proxy ownership is unverified; startup refused(#8552). The proxy runs as PID 1 in a container on every start, so aruntime-port.jsonleft by the previous run names PID 1, which is the starting process itself. The startup recheck (observeProxyLiveness) signals that PID, gets an answer from itself, reads an ocx command line, and classifies the owner as unknown. Every restart refused the same way.After this change, a record that names the starting process's own PID counts as stale only when both conditions hold:
ocx.pidorruntime-port.jsonin its own lifetime, so the writer was an earlier lifetime of the same PID number;ownerScopethat matches where this process runs.writeRuntimePortnow stamps it, and only on the owner's own record.On Linux, matching needs the same host name, plus one of two stronger facts:
/. This is anupperdirin mountinfo with a 64-hex layer id, as used by Docker'soverlay2driver and by containers/storage (Podman and CRI-O). It covers the same container started again, including after a host reboot, and no other container mounts that layer. Three things are deliberately not used. Sequence-numbered containerd snapshots (snapshots/<N>/fs) repeat on nodes built alike. An overlay host root is shared by every sandbox that uses it. A container id is visible to every container joined to that container's network (--network container:, Composenetwork_mode: service:).On other platforms the PID space covers the whole machine, so the host name decides. The scope is stored as digests, never as the host name or ids themselves. If the Linux evidence cannot be read, the scope gets a per-process value that never matches, so the check fails closed.
Before: a container restarted with stale records refused forever. After: a container restarted in place recovers and serves. That covers a Kubernetes container restart in its pod, and the same Docker (
overlay2) or Podman container started again, including after a host reboot. Docker's containerd image store numbers its layers, so a restart there still refuses.These still refuse, with the same message, because an old owner could still be serving the same volume from another network namespace:
hostname(start-first,--uts=host,--network container:), another node, or a root filesystem without a randomly named overlay layer;The new docs section (
guides/remote-hub, "Restarts after an unclean exit") gives the one-time remedy and recommends one writer per state volume (strategy: RecreateormaxSurge: 0for a Deployment).Residual risk, for a shared state volume only, all documented in the guide as unsupported:
The scope is not part of record validity, so a malformed value cannot hide a live owner from status, stop or liveness. Older readers ignore the extra field; the desktop Rust reader has no
deny_unknown_fields.Follow-up, not in this PR: the ownership mutation lease also treats an alive recorded holder PID as live. Its record carries
processInstance, which could prove a same-PID earlier lifetime the same way. #8552 shows no evidence that the lease was involved.Closes #8552
