Outcome

After onboarding is cancelled at Policy presets, nemoclaw <name> destroy --yes can delete the retained sandbox when its live OpenShell identity matches the recovery record. Missing identity, uncertain presence, and observed identity drift block deletion and preserve recovery state. The retained-recovery --force fallback remains a separate review finding described below.

Reason

The previous guard refused every live retained sandbox, including a verified matching sandbox. Existing tests required that refusal, so interrupted onboarding could leave users unable to complete cleanup or onboard again.

Related issues

Refs #10863. PR #12839 covers identity-free recovery after verified absence; it retains the live-sandbox refusal addressed here.

Changes

• Replace the blanket refusal with a guard for missing identity or uncertain presence.
• Reuse the existing OpenShell identity inspection at destroy checkpoints for retained recovery as well as pending creation.
• Remove obsolete cancellation guidance and place the supported destroy command before recovery diagnostics.
• Update existing success expectations and cover replacement identity, uncertainty, final-check identity drift, and failed deletion.
• Correct src/lib/onboard/lifecycle-contracts.md to describe verified live retained-sandbox deletion and the non-atomic name-delete limitation.

Production code has 9 fewer lines. No new cleanup abstraction, command, dependency, or OpenShell API is introduced.

Verification

• Documentation follow-up bd0b14625e9085490bbe1ffdadeef61526ec2e9e: npm run docs passed with zero errors and two Fern warnings. Normal commit hooks, including Markdown lint, passed. Only the retained-recovery description at line 128 changed; table structure is preserved. No new runtime test applies to this prose-only follow-up.

• Baseline retained-recovery and cancellation tests: 40 passed. The revised success cases failed before the fix.

• NODE_OPTIONS=--max-old-space-size=8192 npm run test:changed — 191 affected tests passed across 10 files; all 7 growth checks passed.

• vitest run --project integration test/onboarding/onboard-fresh-create-identity.test.ts -t 'makes a ' — all 3 cancellation integration cases passed, including retained identity, recovery state, and reentry assertions.

• Normal commit hooks — passed, including formatting, lint, repository checks, growth checks, secret scan, and commitlint.

• Normal pre-push validation — passed, including publication checks and CLI, plugin, and JS configuration type checks.

• GitHub commit verification — all three published commits Verified (3ba4ed0963e885dc3b4bf003a98c49a9adbdb1d3, 609d76f21894ee5b7f77565aa9012b0114c0895a, bd0b14625e9085490bbe1ffdadeef61526ec2e9e).

• Live interrupted-onboarding reproduction remains outstanding because Docker is unavailable on the contributor host. Managed startup CI does not cover that reproduction.

• Diff reviewed: no secrets, API keys, credentials, or host-specific reproduction identifiers.

Review notes

Self-review of NVIDIA/NemoClaw commit 609d76f21894ee5b7f77565aa9012b0114c0895a covered the destroy coordinator, execution identity checks, cancellation guidance, and changed tests. The sensitive path is src/lib/onboard/cancel-rollback.ts. Independent reviews of that production/test commit are available from Advisor, CodeRabbit, and the human review comment. The documentation follow-up changes no runtime code.

This restores ordinary explicit-destroy semantics. OpenShell still deletes by mutable name: a different OpenShell client can replace the sandbox after the final identity check. This change does not provide an atomic identity precondition; NVIDIA/OpenShell#3210 tracks that upstream capability.

The maintainer accepted the remaining concurrency risk under the operating assumption that no independent OpenShell client replaces sandboxes during NemoClaw cleanup. Public documentation remains deferred to Docs / Author Post-Merge Catch-Up. The separate P2 --force fallback finding is not waived or repaired by this documentation follow-up. Required merge checks remain separate, and CI for the new documentation commit must be evaluated independently.

Summary by CodeRabbit

• Bug Fixes
  • Retained sandbox cleanup can proceed when the sandbox is confirmed present and its identity can be verified, including when no host container is available.
  • Destruction is blocked when presence is unknown, identity is unavailable, or identity checks detect a change, helping prevent removal of a replacement sandbox.
  • Identity is checked again immediately before deletion; failed checks or deletion preserve the recovery record.
  • Cancellation recovery guidance recommends the destroy command when a durable identity is available. Otherwise, it advises preserving recovery information and checking the owning gateway.

📝 Walkthrough

Walkthrough

The destroy flow now checks retained sandbox identity before deletion. It preserves recovery state when identity cannot be verified or deletion fails. Cancellation rollback guidance recommends destroy when a durable identity fingerprint is available.

Changes

Retained Sandbox Destruction

Layer / File(s)	Summary
Sandbox identity continuity src/lib/actions/sandbox/destroy-execution.ts	Expected identity now uses the pending-create fingerprint when available, otherwise the expected container fingerprint. Continuity checks apply to either identity source.
Retained recovery deletion src/lib/actions/sandbox/destroy.ts, src/lib/actions/sandbox/destroy-retained-recovery-flow.test.ts	A live retained sandbox can proceed to deletion when its identity fingerprint is available. Tests cover successful deletion, identity mismatch, unknown presence, identity drift at the delete boundary, and failed deletion.
Cancellation rollback guidance src/lib/onboard/cancel-rollback.ts, src/lib/onboard/cancel-rollback.test.ts, test/onboarding/onboard-fresh-create-identity.test.ts, src/lib/onboard/lifecycle-contracts.md	Guidance recommends the destroy command when a fingerprint is available. Without one, it advises preserving registry and recovery state and inspecting the owning gateway. The contract documents identity checks before deletion and the non-atomic name-based deletion boundary.

For commit 609d76f21894ee5b7f77565aa9012b0114c0895a, treat the findings from Advisor run 37916599523 as non-blocking for this PR, with the following risk acceptance and deferral.

The security, architecture, migration, delivery, customer-value, and operability findings describe one shared deletion race. Another trusted gateway client can replace the sandbox after the final identity check and before OpenShell processes deletion by name. I accept this remaining concurrency risk to restore explicit destroy --yes cleanup after interrupted onboarding; retaining the blanket refusal leaves #10863 unresolved. The checks reject identity changes observed before submission, but they do not make deletion atomic, and passing CI does not prove this race is closed. NVIDIA/OpenShell#3210 tracks the upstream identity-bound deletion capability.

Defer the public documentation correction to Docs / Author Post-Merge Catch-Up, as permitted by this repository's AGENTS.md. This comment records acceptance of the deletion risk and deferral of documentation work; it does not turn the failed Advisor check green or waive other validation and merge requirements.

[hunglp6d]

Reviewed 609d76f against base 8fce085:

1. [P1] The final identity check does not bind the subsequent name-based delete to that identity (destroy-execution.ts:851,890). Another OpenShell client can replace the sandbox between these operations. The drift test changes identity before the final check, so it misses this window. Preserve the refusal until atomic deletion is available, or obtain an explicit maintainer decision accepting weaker guarantees; documenting the risk alone is insufficient.

2. [P2] The newly admitted retained-sandbox path can reach forcedLocalCleanup (destroy-execution.ts:940). If identity checks succeed but deletion returns connection refused, --force can remove the registry entry and report success when no MCP, host-local inference, or Portable ownership blocks it. The retained recovery record remains unresolved. Exclude retained recovery from this fallback and add a regression test.

3. [P2] Update src/lib/onboard/lifecycle-contracts.md:128 in this PR: it still promises refusal for every live retained sandbox. Public recovery documentation also needs the corresponding catch-up.

Build/typecheck and CLI CI passed, but the final Advisor blocker gate failed. No local tests or live reproduction were run for this review; the interrupted-onboarding live reproduction remains outstanding.

[sandl99]

Regarding the P1 in this review: for this change, the accepted operating assumption is that NemoClaw manages its sandbox namespace and operators do not use an independent OpenShell client to replace same-name sandboxes during NemoClaw cleanup. Under that assumption, I accept the remaining check-to-delete race and consider this P1 non-blocking for commit 609d76f21894ee5b7f77565aa9012b0114c0895a, consistent with the previous risk acceptance.

NemoClaw still uses OpenShell internally, and deletion remains name-based; this operating assumption does not make deletion atomic or exclude other possible concurrent operations. This acceptance applies to the P1 only, not the separate P2 forced-cleanup and internal lifecycle-documentation findings.

[hunglp6d]

Re-reviewed 609d76f against 8fce085.

With the recorded maintainer acceptance of the deletion race, I have no remaining blocking code findings. No additional tests are requested.

Please update src/lib/onboard/lifecycle-contracts.md:128 to describe verified live-sandbox deletion and its non-atomic limitation. Public documentation can follow the agreed post-merge catch-up. Required merge checks remain separate.

Preserve retained recovery state when remote deletion is unconfirmed.

The changed guard allows a retained sandbox with a present live identity and recovery fingerprint to reach destruction. With --force, a definite gateway transport failure selects forcedLocalCleanup and returns ok: true. The caller then removes the registry entry, skips retained-recovery resolution, and prints success.

Prevent forcedLocalCleanup for retained recovery records. This preserves local recovery state and returns nonzero through the existing failure path.
