Summary

Finalize Docker sandbox replacement with one identity-bound lifecycle handoff. The previous container remains the rollback target until its irreversible removal. NemoClaw reports success only after OpenShell acknowledges the exact replacement as Ready, and every synchronous OpenShell handoff probe is bounded by a process-tree timeout.

Related Issue

Fixes #9531

Changes

  • Replace the pre-restart lifecycle-release wait with one finalizer shared by immediate onboarding, deferred onboarding, and managed recovery. The finalizer owns the exact stop, backup removal, restart, and acknowledgement order under one transaction.
  • Require OpenShell Ready, a successful sandbox exec, and proof that the transaction-owned replacement is the sole running labeled container. Treat Deleting as terminal and permit Error to remain transient only while the exact replacement stays running.
  • Keep the previous container as the rollback target until removal. Removal is the explicit irreversible commit point; later failures report that automatic rollback is unavailable and direct the operator to rebuild. Do not create a rollback image, recovery record, persistence format, or fallback framework.
  • Bound synchronous OpenShell lifecycle and final-handoff probes with a Linux process-group timeout that fires before the caller deadline, plus a SIGKILL fallback. This prevents descendants from extending the documented handoff budget ([DGX Spark][Onboard] managed llama.cpp resume hangs past its own 900s timeout waiting for lifecycle record retirement #10238).
  • Preserve the old and replacement container IDs, backup name, last OpenShell phase, and rollback state in failure diagnostics.
  • Remove the live E2E fixture's blind post-helper readiness retry. The fixture now returns the exact replacement receipt, and the E2E performs one readiness assertion before checking that Docker still exposes that exact container.

📝 Walkthrough

Walkthrough

The patch changes sandbox recovery to validate exact replacement containers and final OpenShell handoff acknowledgement. It records the last sandbox phase, preserves backups after unacknowledged handoffs, updates recovery dependency wiring, and expands deterministic and E2E coverage.

Changes

GPU patch handoff

Layer / File(s) Summary
Final handoff probe
src/lib/onboard/docker-gpu-supervisor-reconnect.ts, src/lib/onboard/docker-gpu-supervisor-reconnect.test.ts
The reconnect flow validates the exact running replacement, polls sandbox phases, rejects terminal states, and acknowledges only a confirmed Ready handoff.
Backup finalization flow
src/lib/onboard/docker-gpu-patch-finalize.ts, src/lib/onboard/docker-gpu-patch-types.ts, src/lib/onboard/docker-gpu-patch-diagnostics.ts, src/lib/onboard/docker-gpu-patch-finalize.test.ts
Finalization uses the final handoff timeout, performs the stop/remove/start sequence, reports lifecycle and handoff results, and records the last sandbox phase.
Recreation and cutover integration
src/lib/onboard/docker-gpu-patch-recreate.ts, src/lib/onboard/docker-gpu-sandbox-create.ts, src/lib/onboard/*test.ts
Recreation propagates finalization state into failure context and reports unacknowledged handoffs without treating a healthy container as sufficient.
Recovery dependency wiring
src/lib/actions/sandbox/*, test/e2e/live/*, test/e2e/support/*, test/helpers/*, test/onboard-sandbox-build.test.ts
Managed relaunch and legacy keepalive flows inject OpenShell execution and capture dependencies. Mocks model container identity, lifecycle release, and post-creation sandbox readiness.

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

Merge Risk: 🟠 High · up to bb5d7

The onboarding and recovery flow can delete its only rollback container before proving the replacement is Ready, and can report reconnect success without a successful sandbox execution. A failed handoff could leave the service without a restorable container or commit recovery state prematurely, so the PR is not merge-ready until these checks are enforced.

300-312: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Keep rollback resources until final handoff succeeds.

finalizeDockerGpuPatchBackup removes the old container before OpenShell acknowledgement. If final handoff fails, it returns backupRemoved: true and does not roll back. This branch also calls removeSettledStateBackup() even when finalHandoffAcknowledged is false.

Preserve the container backup and state backup until the exact replacement receives successful final acknowledgement. On acknowledgement failure, restore the backup or retain it for deterministic recovery.

Advisor assessment: Blockers require maintainer review
Next action: Review the blockers below.
Findings: 2 blockers · 0 warnings · 0 suggestions
Synthesis status: Completed · high confidence · 2 blockers · 0 warnings · 0 suggestions

E2E guidance

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

Recommended E2E: None

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

Blockers

PRA-1 Blocker — Preserve process-tree termination for the final handoff probe

  • Location: src/lib/actions/sandbox/process-recovery.ts:765
  • Category: correctness
  • Problem: The supervisor-relaunch adapter drops the final handoff probe's process-tree timeout options before it calls `captureOpenshell`.
  • Impact: A timed-out `openshell sandbox list` probe can leave child processes running during recovery. Later recovery work can then overlap with abandoned OpenShell work.
  • Fix: Forward `killProcessTreeOnTimeout` and `killSignal` from `options` to `captureOpenshell` with the existing timeout.
  • Verification: Read the final-handoff callback at `process-recovery.ts:764-770` and inspect the captured options in a focused supervisor-relaunch test.
  • Test coverage: In `test/process-recovery/process-recovery-supervisor-relaunch.test.ts`, drive the supervisor-relaunch finalization path and assert that `captureOpenshell(["sandbox", "list"], options)` receives `killProcessTreeOnTimeout: true` and `killSignal: "SIGKILL"`.
  • Evidence: `src/lib/onboard/docker-gpu-supervisor-reconnect.ts:187-198` calls `runCaptureOpenshell` with `killProcessTreeOnTimeout: true` and `killSignal: "SIGKILL"` for the final handoff probe. `src/lib/actions/sandbox/process-recovery.ts:764-770` forwards only `ignoreError`, `includeStderr`, and `timeout` to `captureOpenshell`. `src/lib/adapters/openshell/runtime.ts:66-67` supports both options, and `src/lib/adapters/openshell/process-tree-timeout.ts:18-45` implements the process-tree timeout behavior.

PRA-2 Blocker — Correct the Docker GPU finalizer removal guidance

  • Location: src/lib/onboard/docker-gpu-patch-finalize.ts:16
  • Category: docs
  • Problem: The finalizer comment directs maintainers to a nonexistent test and does not name all direct production users of the finalizer.
  • Impact: A maintainer who removes this workaround after native OpenShell GPU support can omit the supervisor-relaunch path or look for lifecycle coverage in a nonexistent file.
  • Fix: Update the regression-coverage and removal-condition comment to name `docker-gpu-sandbox-create-lifecycle.test.ts` and the direct users `docker-gpu-patch-recreate.ts`, `docker-gpu-sandbox-create.ts`, and `actions/sandbox/supervisor-relaunch.ts`.
  • Verification: Search for `finalizeDockerGpuPatchBackup` imports and confirm that each path named in the comment exists.
  • Test coverage: No automated test is appropriate for this source-comment correction; verify the named paths with a repository path and import search.
  • Evidence: `src/lib/onboard/docker-gpu-patch-finalize.ts:16-27` names `docker-gpu-sandbox-create.test.ts` and lists `docker-gpu-patch.ts` as a caller. The checked-out `src/lib/onboard` directory contains `docker-gpu-sandbox-create-lifecycle.test.ts` but no `docker-gpu-sandbox-create.test.ts`. Imports of `finalizeDockerGpuPatchBackup` occur in `src/lib/onboard/docker-gpu-patch-recreate.ts:29`, `src/lib/onboard/docker-gpu-sandbox-create.ts:14`, and `src/lib/actions/sandbox/supervisor-relaunch.ts:15`.

Maintainer blocker: the current revision still removes oldContainerId before lifecycle release and final acknowledgement. If lifecycle release, replacement restart, or acknowledgement fails, the finalizer returns backupRemoved: true and no rollback-capable container remains. The state-file backup in managed relaunch does not cover direct onboarding, which uses the same finalizer.

Issue #9531 requires backup removal before the replacement’s final start, but it also requires a preserved backup when recovery cannot converge. Docker cannot change labels on an existing container, so retaining the labeled backup changes the lifecycle evidence. A maintainer must define the supported recovery artifact and recreation contract before this PR can merge. I have not treated the resolved automated-review thread as proof that the defect is absent.

Size flag: the current diff is 970 additions and 626 deletions across 23 files compared with current main.

Addressed the final-handoff change request in b13eba7.

The repair keeps the contract narrow:

  • Old-container removal is the irreversible commit point before the final replacement start.
  • Failures after that point report that rollback is unavailable and require a sandbox rebuild.
  • No durable recreation artifact or recovery framework was added.
  • The unused exec-only deletion helper was removed.
  • Missing OpenShell execution now fails reconnect qualification instead of reporting success.
  • Post-commit failures carry backupRemoved: true into fixed, bounded diagnostics.
  • The polling implementation assertion and growth-guard violations were removed.

Validation passed: CLI type-check, CLI build, 63 focused lifecycle tests, 87 sibling recovery tests, repository checks, commit hooks, and pre-push checks. Both new commits are GitHub Verified.

The final handoff still crosses the irreversible Docker boundary before it has final OpenShell proof. In src/lib/onboard/docker-gpu-patch-finalize.ts, the replacement is stopped and oldContainerId is removed at lines 187–196; lifecycle release and final acknowledgement happen only afterward at lines 213–264. The lifecycle-release failure, replacement-start failure, and unacknowledged final-handoff paths therefore return backupRemoved: true without a rollback-capable container. This also affects direct onboarding, where a managed-relaunch state-file backup is unavailable.

Please keep the old container recoverable until the exact replacement is acknowledged Ready, or implement a rollback-capable handoff protocol that preserves the old container across every post-removal failure. Add tests that prove lifecycle-release failure, replacement-start failure, and final-acknowledgement failure retain or restore a usable prior container. This requires a lifecycle/design decision rather than a mechanical reviewer patch, because OpenShell name release currently depends on removing the old container.

The unresolved CodeRabbit thread at #10044 (comment) identifies the same ordering defect. The older PR Review Advisor result is for b13eba7105a0bc76141f8f35a47a6947e0ddf102, not the current head, and does not override this current-head finding.

Reviewing latest PR commit cd3669bf858648bbb7bf4c5c4266ee48f9e190ba. Requesting changes for these approval blockers:

  • Product scope: docker-gpu-patch-finalize.ts now creates a Docker image and persists a recovery record. That conflicts with the accepted boundary in issue #9531, which explicitly kept the previous container as the rollback target until removal and excluded a durable recreation artifact, persistence format, and fallback framework. A maintainer product decision must define ownership, lifecycle, cleanup, credential handling, and validation before this supported surface is implemented.
  • Credential safety: docker commit can preserve the container image configuration and writable layer, while the tests prove filtering only for the JSON recovery record. The retained rollback image can therefore contain credentials. A successful commit with missing or malformed stdout also loses the image identifier and leaves no cleanup path.
  • Rollback proof: restorePostCommitRollback treats a successful detached run that returns a container ID as rolledBack, without proving that the replacement remains running, reaches OpenShell Ready, or accepts execution. Callers then report the pre-patch sandbox as restored, and managed relaunch can remove the state backup. The direct failure messages in docker-gpu-patch-recreate.ts:428 and docker-gpu-sandbox-create.ts:528 also omit the required condition that the replacement container must be absent before the recovery action is used.
  • Boundedness: the finalizer retains the synchronous openshell sandbox list lifecycle probe. Issue #10238 reports that this same step ran about 19 minutes despite a 900-second cap because a descendant can keep the synchronous operation blocked. The final handoff does not yet enforce its stated deadline.
  • Test isolation: npx vitest run --project cli for the focused lifecycle set ran 385 tests with 378 passing and 7 failures in docker-gpu-patch-finalize.test.ts. The failing rollback-plan tests omit the injected homedir, so they can reach the real user recovery path instead of a temporary directory. The focused suite must be isolated from user state and pass.

@senthilr-nv Addressed your review in f79330c3:

  • Removed the Docker rollback image, recovery record, persistence format, and post-commit fallback framework.
  • Restored the accepted boundary: the previous container is the rollback target only until its irreversible removal; later failures require a rebuild.
  • Removed the retained-image credential surface and the post-commit rollback-success classification.
  • Bounded synchronous lifecycle/final-handoff probes with a Linux process-group timeout plus SIGKILL fallback ([DGX Spark][Onboard] managed llama.cpp resume hangs past its own 900s timeout waiting for lifecycle record retirement #10238).
  • Re-ran the lifecycle set under a clean temporary HOME (8 files, 118 tests), integration recovery/onboarding (3 files, 55 tests), timeout-adapter coverage (4 files, 89 tests), typecheck, growth/architecture checks, and full PR validation.

Please re-review exact commit f79330c3c99e64c65cad47d8aadd6a2b405d20d5.

Reviewing latest PR commit f79330c3c99e64c65cad47d8aadd6a2b405d20d5. The rollback-image, recovery-record, credential-retention, and test-isolation blockers from my previous review are resolved. Requesting changes for these remaining blockers:

  • src/lib/actions/sandbox/process-recovery.ts:764-770 drops killProcessTreeOnTimeout and killSignal before calling captureOpenshell. Managed supervisor recovery therefore bypasses the new process-tree timeout for the final sandbox list probe. Forward both options and add a focused regression that observes them at captureOpenshell.
  • src/lib/actions/sandbox/process-recovery.ts:505-514 checks replacementRestarted === false before lifecycleReleaseObserved === false. A lifecycle-release timeout occurs before Docker start is attempted, but the operator receives Docker could not start. Restore the lifecycle-release classification and its regression so the ownership diagnostic identifies the failed OpenShell boundary.
  • src/lib/onboard/docker-gpu-patch-finalize.ts:16-27 names nonexistent docker-gpu-sandbox-create.test.ts coverage and omits direct finalizer users. Update the removal guidance to name docker-gpu-sandbox-create-lifecycle.test.ts and the direct callers in docker-gpu-patch-recreate.ts, docker-gpu-sandbox-create.ts, and actions/sandbox/supervisor-relaunch.ts.
  • The new shared process-execution behavior addresses issue #10238, whose current issue record explicitly requires a maintainer scope decision and real DGX Spark evidence. The PR description states that human review selected the behavior and that it prevents descendants from extending the deadline, but it gives no decision or process-boundary evidence. Record the accepted ownership and validation decision before this cross-issue behavior becomes supported.

Superseded by the accepted maintainer boundary: the prior container remains the rollback target until irreversible removal, and the durable post-commit fallback was removed. Exact head 87368cf implements the current human-review direction.

Approved on exact head after addressing the human review blockers: small irreversible handoff scope, no durable rollback artifacts, process-tree-bounded probes including managed recovery, correct lifecycle diagnostics and source guidance, isolated tests, documented #10238 ownership decision, and green CI/security/image validation.
