…does not own `nemoclaw <name> recover` reported the dashboard forward restored and exited 0 while an unrelated process held the port, so the printed dashboard URL and its token went to that process (#11149). #11128 made the healthy check prove listener ownership, so recovery now fails; it still called the forward "missing or dead" and relaunched onto the occupied port, reporting that launch's "already occupied" second-hand. Classify the listener as owned, absent, legacy or unverified. Recovery refuses an unverified listener before any retirement or launch, names the port and the owner lookup, leaves the process untouched, and the probe failure detail carries the port so `recover` exits 1 with forwardAction=failed.

… port A legacy forward row proves nothing about who holds the port today. A stale row over a foreign listener sent `forward stop` and then waited on a port that never releases, reporting a release failure instead of the occupied port.

…ures (#11149) `describeSandboxPortForwardListener` now classifies a `forward list` row as `legacy` only when the listed PID is the port's single live listener. Otherwise the listener is `unverified`, and `ensureSandboxPortForward` refuses before `beforeStart`/`afterSuccess` run the pinned identity probe. The #9364 supervisor-relaunch tests stage a healthy legacy forward so the identity refusal is what fails recovery. With no live PID behind the listed row they stopped at the refusal instead and reported `recovered: true`. Stub `localListenerPids` to the listed PID at every reachable legacy-row site, as `process-recovery.test.ts` already does. Signed-off-by: Dongni Yang <dongniy@nvidia.com>

…11149) `describeSandboxPortForwardListener` parsed OpenShell's legacy `forward list` output twice: `isLegacySandboxForwardListed` to learn that a row exists, then `legacySandboxForwardPid` to read its PID. `legacySandboxForwardPid` now returns `undefined` when no row is listed and `null` when the row's PID is unparseable, so the classifier makes one lookup. `isLegacySandboxForwardListed` had no other consumer and is removed; `legacyForwardPorts` stays for `retireLegacySandboxForwards`. The migration unit test now covers the three results. Its `toBeUndefined` assertions fail on the previous implementation. Signed-off-by: Dongni Yang <dongniy@nvidia.com>

It now exits nonzero when the dashboard port is held by a listener NemoClaw cannot attribute to the sandbox's own OpenShell forward.

… end to end (#11149) The stale-legacy-row refusal was proven only with mocked `localListenerPids` and a mocked row parser, and the CLI foreign-listener case supplied an empty legacy list. A defect in the PID handoff would have passed both. Add a runtime case: a genuine foreign listener holds the dashboard port, the fake `forward list` names the sandbox and port with a PID that is not the listener's, and `recover` runs with the production ownership proof. It must exit 1, print the unattributed-listener diagnostic, issue no `forward stop` or `forward service`, and leave the listener alive. With the PID comparison disabled in the classifier the case fails: recovery reports a restored forward. Signed-off-by: Dongni Yang <dongniy@nvidia.com>

…nning (#11149) A legacy `forward list` row whose PID matched the port's sole listener was classified `legacy` regardless of its STATUS column. A `dead` row keeps the PID of a process that has exited, and the operating system can hand that PID to an unrelated listener; recovery would then retire the row with `forward stop` over a listener it cannot attribute to the sandbox. `legacySandboxForwardRow` replaces `legacySandboxForwardPid` and returns the row's PID and status from the one lookup. The classifier requires the status to be `running` as well as the PID match; anything else is `unverified`, so recovery names the port and leaves the listener alone. New declared-ports case: a reachable listener whose PID matches a `dead` row is `unverified` and triggers neither `forward stop` nor a service launch. It fails on the previous commit (`expected 'legacy' to be 'unverified'`). The migration unit test covers the row's three shapes. Signed-off-by: Dongni Yang <dongniy@nvidia.com>

…d PID (#11149) A `running` legacy row whose PID matched the port's sole listener was enough to retire the row with `forward stop`. A PID that OpenShell recorded can be recycled by the operating system, so the match alone does not prove the listener is the legacy forward. `isListenerProcessExecutable` exposes the executable probe the ForwardTcp ownership proof already uses (`/proc/<pid>/exe` on Linux, `lsof -d txt` on macOS). The classifier now also requires the listening process to run the resolved OpenShell executable before it classifies the row as `legacy`; anything else is `unverified` and left alone. New declared-ports case: a `running` row whose PID runs another executable is `unverified` with no `forward stop` and no launch; it fails on the previous commit (`expected 'legacy' to be 'unverified'`). The synthetic CLI fixture stubs the executable probe alongside the ownership proof, so the legacy migration case still exercises the migration path. Signed-off-by: Dongni Yang <dongniy@nvidia.com>

Outcome
nemoclaw <name> recovernow reports a dashboard port that is held by a listener it cannot attribute to the sandbox's own OpenShell forward, leaves that listener untouched, exits 1, and never says the forward was restored. The refusal names the port, how to find the owner, and the rerun.Reason
With an unrelated process on the dashboard port,
recoverexited 0 and printedrestored dashboard port forward. The dashboard URL NemoClaw prints carries the access token in its fragment, so a user who followed that URL sent the token to whatever had squatted the port.On v0.0.120, the reporter's build, the healthy check for an existing forward was TCP reachability plus "not a tracked legacy forward", so any listener passed. #11128 (merged 2026-09-08, not linked to this issue) made that check prove listener ownership from the PID, executable and argv, so on
mainrecovery already exits 1. It still tells the user the forward is "missing or dead", tries to relaunch onto the occupied port, and reports that launch's second-handHost port N is already occupied. This PR completes the reported expectation: name the occupied port, do not touch the foreign listener, withhold readiness.Related issues

describeSandboxPortForwardListenerreturnedlegacyas soon asforward listnamed the sandbox and port, before any ownership check. Recovery then sentforward stop, waited on a port that never releases, and reported a release failure instead of the occupied port and its remedy. Now the row's PID must be the single process listening on the port (legacySandboxForwardPidreads the PID column;localListenerPidsreuses the ownership proof'slsof//procprobes). Anything else isunverifiedand takes the refusal path with noforward stopand no launch.expected 'legacy' to be 'unverified'), and its legacy cases mock the listener PID to match the row. The two process-recovery cases with a reachable legacy row pin the listener PID to the row's. The runtime fixture's fakeopenshell forward listnow names the PID of the listener it really started, as OpenShell does, so the legacy-migration CLI test runs the real PID match.Behavior change relative to #11128
Recovery no longer attempts a launch onto a reachable port it does not own. Previously the launch failed anyway (
Host port N is already occupied) and the failure was reported second-hand; now the refusal is first-hand and nothing is retired or started first.Verification
