fix(onboard): recover retained sandbox cleanup (#10547)

[prekshivyas]

Outcome

Failed onboarding attempts can now be safely reconciled without deleting by mutable sandbox name. While OpenShell still reports the retained sandbox live, destroy preserves recovery and directs an administrator to immutable create-attempt evidence when available. After OpenShell confirms absence, NemoClaw removes only Docker containers proven to belong to the retained immutable identity, verifies their absence, clears the matching recovery state, and permits fresh onboarding. Unrelated explicit sandbox names are not blocked by the retained attempt.

Reason

A post-create onboarding failure could leave the main sandbox container and a bootstrap container behind while a recovery-only session permanently blocked onboarding. The old destroy path required exactly one same-name managed container and could not complete cleanup after OpenShell had already removed the primary sandbox.

Fixes #10547

Changes

• Persist a gateway-scoped retained-recovery record with the sandbox name, immutable identity evidence, policy evidence, and create-attempt label when available.
• Select cleanup authority only when the record matches current registry, session, or immutable Docker evidence; reject missing, changed, foreign, or ambiguous authority.
• Refuse automatic deletion while OpenShell reports the retained sandbox live because OpenShell deletion accepts only a mutable name. Preserve the record and print the identity-bound administrator action.
• After OpenShell confirms absence, snapshot and revalidate every same-name managed Docker container, remove only the prequalified exact IDs, and confirm that no labeled container remains.
• Keep recovery idempotent across partially completed container removal and either recovery-state write failure.
• Release the matching recovery-only session and retire only the unchanged independent record after verified cleanup.
• Block same-name onboarding and rebuild before lifecycle effects while recovery remains unresolved, but permit nemoclaw onboard --name <different-name> without changing the retained record.
• Print the exact ai.nvidia.nemoclaw.create-attempt=<value> selector on post-create failures and cancellations when available.
• Partition legacy retained-recovery records by their verified gateway identity during non-default port migration, preserving records for other ports and publishing the selected recovery authority before exposing its moved session.
• Make managed-image MCP qualification cleanup act as the trusted test administrator: remove its exclusively owned OpenShell sandbox first, then run normal NemoClaw reconciliation. Production cleanup remains fail-closed.
• Document the fingerprint, label-only, and no-fingerprint/no-label operator outcomes without suggesting mutable-name deletion.

Verification

• Final head: 9164a3c9a11ba58da9c0fd433a82551aab423a78.
• npm run typecheck:cli passed locally and in the pre-push gate.
• npm run docs:strict passed, including generated variant synchronization, route validation, and Fern validation.
• Expanded affected CLI suite: 11 files / 275 tests passed, covering retained recovery selection, exact Docker cleanup, same-name replacement refusal, rebuild refusal, cancellation, cross-process recovery state, and malformed inspection.
• Retained-recovery state suite: 13/13 passed in an isolated rerun after a parallel 5-second host-contention timeout.
• Legacy gateway migration suite: 18/18 passed, including mixed-gateway record partitioning, migration without a matching session, conflicting-identity refusal without mutation, interrupted retry after authority publication, fail-closed rejection of an older incomplete intent, and preservation of the same-name onboarding block.
• MCP E2E administrator-cleanup regression: 3/3 passed; E2E client fixtures: 75/75 passed; mock/live parity validator: 15/15 passed.
• Process-level fresh-create onboarding: 16/16 passed, covering runner, registry, recovery persistence, retry, finalization, exact label output, and post-create cancellation failures.
• Semantic E2E phase validation: 134 tests across 90 files passed.
• Growth guardrails: 32/32 passed.
• Commit and push hooks passed formatting, lint, repository checks, environment-documentation checks, secret scanning, Markdown lint, source-shape budget, growth guardrails, commitlint, and CLI TypeScript.
• Final exact-head managed-image qualification passed Pi image validation on both architectures, staging permission QA, direct startup for OpenClaw/Hermes/Deep Agents Code, exact all-agent activation, and two independent exact OpenClaw MCP discovery passes. Each MCP risk signal identifies expected/tested candidate 9164a3c9a11ba58da9c0fd433a82551aab423a78, reports runReason: passed, and records zero failures; all five phases passed in each run and both cleanup manifests contain no failures. Pre-cleanup evidence confirms the initialized gateway was visible to raw OpenShell. All-agent activation passed all 12 phases, exercised nine agent turns across all three shipped agents, and recorded zero cleanup failures.
• Final exact-head focused E2E: onboarding repair and interrupted-resume run passed. Both uploaded evidence manifests identify candidate 9164a3c9a11ba58da9c0fd433a82551aab423a78 and trusted workflow 8c42560869ca7003b652217b769831b6b8b342d4; both risk signals identify the same expected/tested candidate and correlation a50b555e-b887-4da7-8531-4bcb76ebd8a5, report runReason: passed, and record zero cleanup failures. All 17 scenario phases passed.
• Final exact-head self-hosted PR E2E run passed, including sandbox lifecycle, gateway isolation, port overrides, non-root smoke coverage, sandbox-image builds on both architectures, and generic NVIDIA GPU selection.
• Final exact-head main PR CI passed all 12 CLI shards, aggregate CLI coverage, static checks, installer integration, plugin tests, build/typecheck, and audits.
• Final exact-head PR Advisor run completed successfully. Eight specialists found no required change, including Documentation after the final clarification. Operations repeated a proposal to add administrator-supplied identity for legacy records; the disposition records why that is intentionally outside this fix and conflicts with the accepted fail-closed boundary for ambiguous identity.
• Exact-head CodeRabbit review requested in PR comment 5460275179 completed with no actionable comments for the 9b5b1bbc0 to 9164a3c9a delta and reports low merge risk through the final head. Its only residual note is bounded documentation ambiguity, not runtime risk.

Review notes

The maintainer accepted the fail-closed behavior and recovery boundary in #10547 (comment).

Advisor findings were repaired incrementally: late foreign-container conflicts, repeated-destroy convergence, recovery state ordering, multi-record selection, exact Docker observation reuse, rebuild admission, E2E cleanup ordering and mock parity, conditional operator documentation, and non-default gateway migration of the independent recovery owner.

The exact-head Advisor run on f84bd7992c found that whole-file non-default-port migration could transfer recovery records owned by other gateways. 4e9f5d0bf replaces that move with record-level gateway partitioning, adds mixed-port/no-session/interrupted-retry/conflicting-identity regressions, and makes create-attempt-label documentation neutral about where the label originates.

CodeRabbit's exact-head review of 4e9f5d0bf identified that an already-published older version-1 migration intent could omit the new recovery partition. ed383e54b refuses that incompatible intent before mutation while leaving recovery evidence safely in the shared root, with a regression proving the registry, recovery record, and intent remain unchanged.

The managed-image MCP E2E exposed two runner-isolation gaps. 12ea021ef first lets the production CLI safely initialize or recover the gateway before trusted administrator cleanup. Artifacts from that run then showed that the raw OpenShell subprocess received only PATH, so 47709ad575 supplies a sanitized availability-probe environment and an explicit gateway name before the isolated identity-bound delete. The regression proves the ordering, environment contract, and continuation when safe cleanup refuses a retained identity.

9b5b1bbc0 distinguishes immutable runtime identity from Docker-only evidence in operator guidance. 9164a3c9a makes the recovery procedure conditional and explicit: a record without immutable identity remains fail-closed for only the affected sandbox name, and this flow does not accept administrator-supplied identity.

The proposal for a new command that lets an administrator supply identity for a record created without immutable identity evidence is intentionally not implemented here. Such a command would create a new privileged authority surface. When OpenShell returned neither a fingerprint nor a create-attempt label, NemoClaw remains fail-closed, preserves terminal evidence, and permits a different explicitly named sandbox; it does not clear the retained name based on mutable-name absence alone.

The broad local npm run test:changed phase oversubscribed the 8 GiB development host and produced unrelated 5-second timeouts. Affected suites were rerun independently and passed as recorded above; PR CI is authoritative for the broad suite.

The full live-FSM subprocess file is not cited as green: its broad slice exits before emitting the JSON payload on this host, and an isolated checkout of unmodified upstream main reproduces the same initial-slice failure. The branch-specific retained-recovery admission case passes.

📝 Walkthrough

Walkthrough

The destroy flow now validates retained sandbox fingerprints across multiple containers, performs exact cleanup, and resolves recovery records durably. Recovery-only onboarding accepts a different sandbox name. Rebuild preflight blocks unresolved recovery. Gateway migration moves retained recovery state by gateway.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to 9164a

The PR changes retained-sandbox cleanup and onboarding admission; the remaining risk is a bounded documentation ambiguity about when the one-container destroy rule applies, which could mislead operators but is mergeable with owner follow-up and does not affect runtime behavior.

Clear sandboxName when retained recovery does not match the session.

When retainedRecoveryAuthority is present and routed cleanup is not handled, the generic compare-and-swap is skipped. resolveRetainedSandboxRecovery clears current.sandboxName only when current.cancellationRecovery matches all retained-record fields. Otherwise, it only retires the recovery record. A session with sandboxName === sandboxName and no matching cancellationRecovery therefore keeps a reference to the destroyed sandbox. Gate suppression on a matching recovery record, or run the compare-and-swap when no match exists.

Preserve the final OpenShell identity check for retained recovery.

When pendingPolicyVerification exists, sandboxConfirmedAbsent is true, Docker reports expectedContainerIdentities: [], and the fingerprints match, this branch skips inspectOpenShellSandboxIdentityFingerprint. If a same-name replacement exists before it emits a Docker container, the later Docker check also matches the empty proof. The subsequent runOpenshell(["sandbox", "delete", ...]) may then delete the replacement.

Replace this shortcut with a live OpenShell check that accepts confirmed absence and rejects a different fingerprint. Add a regression test that creates a same-name replacement before the delete boundary and asserts that sandbox delete is not called.

test/helpers/destroy-flow-test-harness.ts (1)

544-557: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Reset exactDockerCleanupPhase between destroy runs, or let setDockerIdentityResult override it.

exactDockerCleanupPhase is set once the exact-cleanup helper runs, and it is never cleared. exactCleanupResult has the highest precedence at Line 552, so every later identity probe in the same harness returns the cleanup-derived output. In a multi-run test such as the recovery-authority-loss test, a later setDockerIdentityResult(...) call has no effect on the identity probe. Today the derived output happens to be empty, so the assertions still hold, but a future test that configures a non-empty identity result after a cleanup phase would pass without exercising its claim.

Add a reset hook, or make the explicit setter authoritative.

♻️ Proposed change: make the explicit identity result win

     setDockerIdentityResult: (result) => {
       dockerIdentityResult = result;
+      // An explicit identity result belongs to the next destroy run, so clear

Inline comments:
In `@docs/reference/commands.mdx`:
- Around line 461-463: Update the destroy recovery documentation near the
retained-recovery cleanup rules to explicitly allow removal of multiple
qualified managed containers when every immutable sandbox ID matches the
retained recovery fingerprint, and scope the existing single-container
restriction to ordinary destroy flows. Keep foreign containers, identity
mismatches, failed probes, and ambiguous records as cleanup blockers.

In `@src/lib/onboard/cancel-rollback.ts`:
- Around line 81-83: Update the guidance assembled by SandboxCancelRollback.arm
so it does not require a displayed create-attempt label when recoveryContext is
undefined; condition the label instruction on recoveryContext and otherwise
direct operators to use the displayed sandboxIdentityFingerprint. Preserve the
existing destroy and identity-bound removal guidance.

PR Advisor Operations finding disposition: non-actionable for #10547 under the accepted maintainer decision in #10547 (comment).

A recovery record without an immutable fingerprint is ambiguous. The approved behavior keeps only that affected sandbox name locked while allowing unrelated explicit names. Retiring it from mutable-name absence would weaken the fail-closed boundary, while accepting administrator-supplied identity would add a new privileged authority surface outside this fix. The final documentation now states this limitation and safe unrelated-name path explicitly.

Approved latest PR commit c9c4b5e8d97de90c5f2ee715f2b602730108f9e5 after accepted-scope, architecture, lifecycle, data-safety, documentation, and nine-category security review.

The review verified immutable sandbox, gateway, policy, lifecycle, route, and recovery-record binding; fail-closed live/ambiguous/stale authority behavior; bounded exact-ID Docker cleanup; session/record and migration serialization; restart/retry convergence; and provider/credential containment. The two review repairs are signed, DCO-compliant, GitHub Verified, and covered by adversarial regression tests.

All five ruleset-required contexts are successful. Main CI, CodeQL/ShellCheck, self-hosted E2E, managed-image multi-architecture/startup/all-agent/MCP qualification, strict docs, focused tests, type-checking, and full PR validation passed. All inline threads are resolved. The Operations advisor was unavailable because its workflow credential was rejected; its artifact reported no blocker, warning, or suggestion, and the independent operations review is complete.
