fix(cli): refuse sandbox destroy when the sandbox-name label is disputed

[Dongni-Yang]

Summary

nemoclaw <name> destroy --yes deleted the real sandbox with exit 0 while a foreign container carried the same openshell.ai/sandbox-name label with a different openshell.ai/sandbox-workspace value. Destroy now enumerates every container that claims the sandbox-name label before any destructive step and refuses with exit 1 when the claims do not share one OpenShell-managed identity.

Related Issue

Closes #8999

Changes

• src/lib/onboard/openshell-docker-sandbox-containers.ts: add queryDockerSandboxNameClaims, a status-bearing lookup that lists containers by the sandbox-name label deliberately WITHOUT the managed-by=openshell filter the other lookups apply, then reads each claim's managed-by and sandbox-workspace labels through one docker inspect with a {{json ...}} template. It validates 64-hex container IDs, caps output size, and rejects NUL bytes.
• src/lib/domain/sandbox/destroy.ts: add the pure classifier hasAmbiguousSandboxContainerIdentity. A claim without openshell.ai/managed-by=openshell, or two claims that record different non-empty workspace values, is a dispute. An absent workspace label is not a dispute, so retained pre-v0.0.99 OpenShell containers do not block destroy.
• src/lib/actions/sandbox/destroy-preflight.ts: resolve the container identity as the first step of prepareSandboxDestroy, before gateway selection, NIM stop, MCP mutation, and the OpenShell delete. On a dispute, print each claim with control characters stripped, state that nothing was changed, give the docker inspect / docker rm -f remediation, and exit 1. --force skips the gate with a warning, so a label squatter cannot block destroy forever. A Docker failure or unparsable answer prints a warning and continues, so non-Docker drivers and hosts without Docker keep the current behavior.
• Tests: repro-shaped flow tests (refusal before any mutation, --force proceed with warning, Docker-unavailable warning), focused query/resolver/render tests that pin both docker argvs, and classifier truth-table cases.
• Docs: docs/reference/commands.mdx destroy section documents the check, the refusal, the remediation, the --force skip, and the warn-and-continue fallback.

Known limits, stated on purpose:

• The gate detects label disagreement. A container that copies all three labels is indistinguishable by labels; labels are tamper evidence, not an integrity boundary. Container-create rights imply Docker-socket access, which is host-equivalent already.
• nemoclaw <name> rebuild deletes through its own phase and does not run this gate. Follow-up candidate if maintainers want parity.
• The probe uses the default docker CLI resolution like the other lookups in openshell-docker-sandbox-containers.ts, not the pinned destructive-cleanup authority.

Type of Change

• Code change with doc updates

Quality Gates

• Tests added or updated for changed behavior
• Docs updated for user-facing behavior changes
• Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging)
• Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: pending maintainer review

Documentation Writer Review

• Documentation writer subagent reviewed the completed changes
• Result: docs-updated
• Evidence: docs/reference/commands.mdx (destroy section); review corrected the recovery gap for all-managed disputes, the --force statement, the fallback-scope sentence, rerun wording, and active voice in the CLI refusal text
• Agent: Claude Code

Verification

• PR description includes a Signed-off-by: line and every commit appears as Verified in GitHub
• Normal pre-commit, commit-msg, and pre-push hooks passed, or npm run validate:pr passed after refreshing origin/main when hooks were skipped or unavailable
• Targeted behavior tests pass for the current change set, or tests are marked not applicable above — command/result: npx vitest run --project cli src/lib/actions/sandbox/destroy-preflight.test.ts src/lib/domain/sandbox/destroy.test.ts src/lib/actions/sandbox/destroy-flow.test.ts src/lib/onboard/openshell-docker-sandbox-containers.test.ts → 4 files, 78 tests passed. npm run typecheck:cli, npm run checks:repository, and npm run docs pass. The 35 test:changed failures on this host reproduce unchanged on an unmodified checkout (relative PATH entry breaks the managed llama.cpp authority tests; the host lacks jq for five e2e-support files; one load-induced 5s timeout passes in isolation).

📝 Walkthrough

Walkthrough

The destroy flow now validates Docker container ownership before deleting sandbox resources. Ambiguous claims block destruction unless --force is used. Unavailable identity checks warn and allow destruction to continue.

Changes

Sandbox destroy safety

Layer / File(s)	Summary
Docker claim discovery src/lib/onboard/openshell-docker-sandbox-containers.ts, src/lib/actions/sandbox/destroy-preflight.test.ts	Docker containers with the sandbox-name label are inspected for management and workspace metadata. IDs, responses, output size, and errors are validated.
Identity classification src/lib/domain/sandbox/destroy.ts, src/lib/actions/sandbox/destroy-preflight.ts, src/lib/domain/sandbox/destroy.test.ts, src/lib/actions/sandbox/destroy-preflight.test.ts	Container claims are classified as ambiguous, unambiguous, skipped, or unavailable. Unmanaged containers and conflicting workspace identities are ambiguous.
Destroy identity gate src/lib/actions/sandbox/destroy-preflight.ts, src/lib/actions/sandbox/destroy.ts, src/lib/actions/sandbox/destroy-flow.test.ts, src/lib/actions/sandbox/destroy-preflight.test.ts, docs/reference/commands.mdx	Ambiguous identities refuse destruction before mutation. --force bypasses the refusal with a warning. Unavailable checks warn and continue. Output sanitizes container metadata.

Estimated code review effort: 4 (Complex) | ~45 minutes

Mergeability Score: ⚪ Minimal · up to ed293

The change adds a bounded destroy preflight check with documented fallback and force behavior; no actionable merge-blocking risk remains beyond normal checks and review.

5 terminology differences from the second opinion

Advisory only. These are normalized differences from the primary terminology receipt.

• sandbox-name claim at src/lib/actions/sandbox/destroy-preflight.test.ts:31: primary classified it as define; the second opinion classified it as justified.
• disputed at src/lib/actions/sandbox/destroy-preflight.ts:44: selected only by the second-opinion lane as justified.
• OpenShell-managed identity at src/lib/actions/sandbox/destroy-preflight.ts:42: selected only by the second-opinion lane as justified.
• label squatter at src/lib/actions/sandbox/destroy-preflight.ts:122: selected only by the second-opinion lane as define.
• ambiguous container identity at src/lib/domain/sandbox/destroy.test.ts:19: selected only by the second-opinion lane as justified.

2 additional E2E selections from the second opinion

Advisory only. The primary lane did not select these E2E jobs or targets.

• ubuntu-policy-custom-missing-presets-negative: The completed second-opinion lane identified E2E coverage that the primary lane omitted.
• sandbox-survival: The completed second-opinion lane identified E2E coverage that the primary lane omitted.

Second-opinion terminology and E2E selections are advisory. Live E2E does not run automatically for pull requests.

3 semantic terminology decisions

Terminology decisions are advisory. They affect the assessment only when a separate finding identifies concrete semantic impact.

• established — container identity at src/lib/actions/sandbox/destroy-preflight.ts:145: Keep `container identity` for Docker identity evidence.
• define — OpenShell-managed identity at src/lib/domain/sandbox/destroy.ts:58: Keep the term and its adjacent definition because it distinguishes OpenShell-managed containers from foreign label claimants.
• define — sandbox-name claim at src/lib/actions/sandbox/destroy-preflight.test.ts:31: Keep the term for label presence and distinguish it from verified OpenShell management.

E2E guidance

Advisory only. A maintainer can dispatch the default E2E suite for the commit under review.

Recommended E2E: None

Manual-only E2E: onboard-repair, onboard-resume, cloud-onboard
The manual PR workflow does not run these selectors for the commit under review. Run them from reviewed code on main.

Warnings

Warnings do not block.

PRA-1 Warning — Do not bypass the identity gate when Docker evidence is unavailable

• Location: src/lib/actions/sandbox/destroy-preflight.ts:143
• Category: security
• Problem: The preflight warns and continues when Docker cannot provide or parse container identity evidence.
• Impact: A transient Docker query or inspect failure can bypass the new gate and delete the registered sandbox while an unmanaged same-name container remains.
• Recommendation: Refuse destroy without `--force` when the identity query is unavailable, and retain the explicit `--force` override for an operator who verifies the target.
• Verification: Inspect `prepareSandboxDestroy` with a query result of `{ outcome: "unavailable" }` and confirm that no destructive operation can execute without `--force`.
• Test coverage: Add a destroy-flow test where the Docker claim query fails and assert that non-forced destroy exits before every mutation, while `--force` proceeds with a warning.
• Evidence: src/lib/actions/sandbox/destroy-preflight.ts:143-148 continues after an `unavailable` result. docs/reference/commands.mdx:2163-2164 documents that Docker failures or unparsable output skip the check and continue. src/lib/actions/sandbox/destroy-flow.test.ts covers the Docker-unavailable path as a successful destroy.

Workflow run details

This automated review informs maintainers. Warnings and suggestions do not require a response. A maintainer decides whether to merge.

[cv]

Maintainer review decision: skip this implementation in favor of #9042.

This PR deliberately warns and continues when docker ps or docker inspect cannot provide container identity evidence. It also checks identity only during preflight. For sandbox deletion, missing evidence cannot authorize the action, and the accepted identity can change before openshell sandbox delete runs.

Correcting those gaps would replace the PR's stated fallback and extend its design through the deletion boundary, which is beyond a narrow maintainer fix. #9042 fails closed when the probe is unavailable, requires one complete managed identity, and revalidates that identity at the deletion boundary.

The quoted-label output finding is fixed, and the regression tests otherwise cover this PR's stated behavior. This decision does not request further changes to #9057.

[apurvvkumaria]

Supersession evidence is now complete: #9042 contains the accepted fail-closed implementation through the synchronous deletion boundary at 3ba0ea7f.

Dongni's diagnostic-label quoting fix is preserved in #9042 with its original authorship and DCO as 68abe49d, adapted from the original contribution at ed293a85.

Thank you, @Dongni-Yang, for the security-focused contribution and regression coverage.
