If the destroy operation fails, NemoClaw keeps the local shields state and the auto-restore timer. Detached auto-restore uses one 7-attempt recovery budget to restore lockdown. Waiting for a verified live sandbox mutation owner does not consume an attempt. The deadline gate remains closed during that wait. If the recovery budget is exhausted, durable containment blocks new sandbox mutations. Run `$$nemoclaw shields status` and follow its exact-generation recovery guidance. If deletion fails after hardening, the command keeps the surviving sandbox's locked shields state instead of cleaning it up as though deletion succeeded. By default, unattended final-sandbox destroys (`--yes`, `--force`, or `NEMOCLAW_NON_INTERACTIVE=1`) remove the shared NemoClaw gateway on macOS so the host listener is released, while Linux preserves it for reuse. Pass `--cleanup-gateway` to force removal, or `--no-cleanup-gateway` to force preservation. These flags always override both `NEMOCLAW_CLEANUP_GATEWAY` and the platform default. If the pre-delete workspace wipe completes with a nonzero status, `destroy` continues, but the retained volume may still contain old files. Use a different sandbox name to avoid reusing that retained volume. If workspace cleanup reaches its 60-second timeout, NemoClaw cannot confirm the remote result. NemoClaw stops before provider cleanup and sandbox deletion, attempts to restore any prepared MCP state, and preserves the local registry entry.

If a shields auto-restore timer remains active, run `$$nemoclaw shields status` to verify bounded recovery or follow its durable-containment guidance, then retry `destroy` only after shields recovery permits it. If no timer remains active, retry after the recorded gateway is available. Cleaning up the gateway after the last sandbox also purges the shared cluster volume that retains the per-name persistent volume. If NemoClaw detects active SSH sessions before destroy, it warns that destroy terminates them with a Broken pipe error and lists their process IDs. This warning prints before the confirmation prompt and when `--yes` or `--force` skips that prompt. If final gateway cleanup finds a live PID-file process whose command line does not prove it owns the target gateway, `destroy` exits non-zero after sandbox and registry deletion and skips gateway and volume removal. NemoClaw preserves the per-gateway PID file and runtime marker so you can inspect the process. Stop only the listener that matches the target gateway, then rerun `destroy` to converge cleanup. When the default-port gateway runs under the packaged OpenShell gateway service, gateway cleanup stops that service before it reaps host processes, so the gateway port is released instead of being rebound by the service manager. The service is stopped, not disabled or removed, and the next onboarding run starts it again. On headless Linux, the packaged service can exist while its `systemd` user manager is unavailable and the gateway runs through the standalone fallback. For this recognized manager-unavailable failure only, `destroy` uses the per-gateway PID file when the service is not enabled for automatic activation. If the recorded PID is live, its command line must match the exact gateway name and port before `destroy` stops it. If the recorded process has exited, `destroy` continues only after it verifies that the gateway port is free. If a live PID does not prove gateway ownership or the port remains occupied, `destroy` exits non-zero and preserves the runtime evidence for inspection. For any other service stop failure, `destroy` exits non-zero after sandbox and registry deletion, prints the status command for the service, and skips gateway and volume removal. If the OpenShell command completes with a gateway transport error and the sandbox has no managed MCP ownership state, `--force` removes only NemoClaw's local registry entry and local artifacts. Gateway-side deletion remains unconfirmed, shared host-service and gateway teardown are skipped, and the sandbox and retained volume may still exist if the gateway returns. Start the gateway with `$$nemoclaw status` and retry destroy when you need a confirmed deletion. If the OpenShell sandbox deletion command reaches its 60-second timeout, NemoClaw cannot confirm whether OpenShell deleted the sandbox.

If the preceding output also reports a failed pre-delete re-lock, run `$$nemoclaw shields status` to verify recovery or follow its durable-containment guidance, then retry `destroy` only after shields recovery permits it. Otherwise, retry after the recorded gateway is available. Managed MCP ownership disables the local-only fallback because exact provider cleanup requires the retained ownership state, and other delete failures remain fatal.

Gateway restart generates a fresh nonce and enters `nemoclaw-gateway-control` as root with injection-capable environment variables cleared. The direct topology publishes a root-owned request to PID 1, while the OpenShell-managed topology executes `managed-gateway-control.py` directly. Both paths prove the replacement gateway and health state before the host repairs port forwards or reports success. -Terminal agents do not run these gateway branches; their Shields transitions use the state and verification branches. - -Shields mutations acquire the host transition lock before changing network policy, config posture, timer authority, or host state. -The coordinator applies the selected agent's config transition, invokes `state-dir-guard.py`, verifies the resulting posture, then commits host state and audit output. -Rollback keeps the same lock and transaction token so a stale callback cannot adopt the transition. -For `provider-state-mutation-v2`, the coordinator first recovers any retained target with matching identity, then acquires and repeatedly asserts the durable provider fence around publication and fresh Hermes activation. -An in-flight privileged execution lease drains before the fence becomes active, and later ordinary command transports are rejected before they resolve or spawn a sandbox command. -The fixed publisher applies the recursive target, the startup gate authenticates the candidate after the complete topology is healthy, and only then can the provider record release and let ordinary execution resume. -If the host process exits, the durable ledger and in-container fence remain the recovery authority for the next Shields command. +NemoClaw policy commands read and update the live OpenShell policy. +They do not persist a second desired-policy document. ## Filesystem and Descriptor Proofs Production Python guards bind privileged helpers and parser dependencies to fixed installed paths. -The managed controller enables alternate procfs and filesystem roots only when a source checkout also sets the explicit `NEMOCLAW_MANAGED_CONTROL_ALLOW_NONROOT_TEST=1` test flag. -They open trusted directories and files with no-follow and close-on-exec flags, compare descriptor metadata, and reject unsafe owners, modes, link counts, mounts, and inode replacement. -They bound file size, entry count, logical bytes, journal size, and process-table traversal before reading attacker-influenced state. -Atomic replacement uses fresh files in the already opened parent directory and verifies the installed inode before the transaction commits. +They open trusted directories and files with no-follow and close-on-exec flags. +They compare descriptor metadata and reject unsafe owners, modes, link counts, mounts, and inode replacement. +They bound file size, entry count, journal size, and process-table traversal before reading attacker-influenced state. +Atomic replacement uses fresh files in an already opened parent directory and verifies the installed inode before the transaction commits. OpenClaw writes from NemoClaw must be strict JSON. Existing OpenClaw runtime config can contain JSON5 comments or trailing commas, so restart validation retains the packaged JSON5 parser for read compatibility.

The managed controller uses a stronger process key because OpenShell remains PID 1 while nonroot children can be replaced. -Its key includes PID, start identity, parent PID, user IDs, namespace PID and inode, command line, process state, and procfs device and inode metadata. -It excludes an empty-command-line process only when two descriptor-pinned captures both report zombie state and exactly one thread. -Every other empty command line, including a zombie capture that reports additional threads, causes discovery to fail closed. +Its key includes PID, start identity, parent PID, user IDs, namespace identity, command line, process state, and procfs metadata.

A different explicit sandbox name starts a fresh session without changing the retained record. Exact provider-owned GPU cleanup can proceed through its owner receipt. NemoClaw attempts to remove temporary policy and build-context sources and reports cleanup failures with the onboarding error; post-create failures retain recovery state.

A new re-onboard run takes current flags, environment, and prompts as intent while registry/gateway state provides drift evidence. The machine resolves a complete secret-free create intent, including policy, messaging/provider, GPU, resource, disabled-channel, and agent inputs, before repair/removal or live recreation. | Ordinary live recreation conditionally backs up before provider cleanup, **delete**, and image removal. The recreate journal preserves the source registry row after deletion. Replacement registration commits the new row after readiness and validation.

Raw credential values remain outside the session. A missing process value can be rebound only when the same OpenClaw session recorded successfully registering that provider and its live provider name, provider type, and credential key still match; otherwise interactive resume requests it again and non-interactive resume exits with environment-variable guidance. Credentials are checked before mutation and again immediately before materialization. | A failed replacement keeps the source registry row. Restore failures warn and can still publish the replacement; managed-DCode live-selection failure leaves a running, unregistered sandbox with manual-delete guidance.

Handoff preparation proves the selected runtime provider and its `clone` capability, exact current registry generation and live-identity fingerprint, snapshot/source workload equivalence, snapshot runtime generation, and the state layer's selected-manifest/payload digest. It rebinds the secret-free startup profile, messaging intent, dashboard identity, and provider-owned contributions for OpenClaw, Hermes, or DCode without a central Podman-specific switch. Provider preparation then resolves active application bindings plus provider-contributed bindings, treating a live exact provider as reusable only when the destination registry independently proves that same logical binding. | The handoff and provider plan are inert. The internal materializer can create only bindings proven absent at preflight; it never updates or deletes an existing destination-owned provider. Immediately before each create it revalidates the source and optional destination registry rows plus the exact `SnapshotRestoreAuthority`. Production snapshot restore does not invoke this transaction and continues to reject cross-sandbox managed-image restore through `rejectManagedSnapshotCloneUntilRebind`; no user-visible clone support is advertised. | Both plans are deeply frozen and secret-free. A successful create produces an exact process-local ownership receipt; a non-zero create reconciled to an exact provider remains ambiguous and unowned.

Remove clears QR-backed durable state when applicable, detaches gateway/bridge state, removes policy, then persists the plan. During `channels remove`, OpenClaw WeChat can clear its manifest-declared legacy state and current plugin account state from an identity-pinned stopped Docker volume after normal cleanup fails. If that cleanup fails, the command stops before policy and plan teardown. A queued rebuild has a separate delete boundary. | The compact registry messaging plan is authoritative; render/build/runtime/state/health entries and nested host-forward details are rehydrated rather than persisted.
