Outcome

Hermes Portable lifecycle operations now use one host-scoped lock policy. Start, stop, launch, connect, status, doctor, and recovery no longer acquire a gateway-scoped lock before entering Portable receipt authority.

Reason

PR #11336 fixed the immediate non-default-port lock path for onboarding, start, stop, and probe-only connect. Its review found that the policy still had three owners. Other supported lifecycle paths could acquire the gateway lock first, then enter code that required the Portable lock. Opposite lock order across commands could block concurrent operations.

Related issues

Refs #11336

Changes

  • Add one Portable lock policy owner for receipt classification and the host-scoped state directory.
  • Route supported async and sync sandbox lifecycle consumers through the same lock wrapper.
  • Acquire the Portable host fence before the receipt-owned lifecycle lock.
  • Make direct synchronous Portable callers fail closed unless they already hold the host fence.
  • Keep ordinary sandbox operations on their existing gateway-scoped lock.
  • Add serialization, non-default-port connect, and public onboarding boundary tests.
  • Lower the architecture budget after reducing direct lifecycle-lock fan-in.

Verification

  • Focused CLI and integration suite — 240 tests passed across 11 files.
  • npm --prefix nemoclaw run build — passed.
  • npm run build:cli — passed.
  • NODE_OPTIONS=--max-old-space-size=8192 npm run typecheck:cli — passed.

Review notes

This PR changes onboarding and runtime lifecycle synchronization. It addresses the architecture and verification follow-ups from the PR #11336 review advisor run.

The first CodeRabbit review found that direct synchronous callers did not enforce the host fence and that the connect test observed mock arguments. Commit 151a1e49800e6d98c380baccf56cf5e43783b45d fixes both findings. The public connect test now accepts a valid host receipt while a copied gateway-scoped receipt is invalid.

A local npm run test:changed run on the active Portable seat observed ambient host state in unrelated tests. CI must provide the broad isolated test result. The focused lock, connect, onboarding, status, doctor, and recovery tests passed.

Walkthrough

The change centralizes Portable lifecycle lock resolution, applies host-scoped fencing through sandbox lifecycle wrappers, migrates sandbox operations from MCP locking, and updates CLI, onboarding, integration tests, and architecture-budget validation.

Changes

Portable sandbox lifecycle locking

Layer / File(s) Summary
Portable lock option resolution
src/lib/onboard/experimental/portable-lifecycle-lock.ts, src/lib/onboard/experimental/hermes-portable-onboarding.ts, src/lib/onboard/experimental/portable-agent-lifecycle.ts, src/lib/onboard/runtime-provider/docker.ts
Portable lock options derive host-scoped state and apply when a Hermes Portable receipt candidate exists. Onboarding and runtime providers use the shared resolver.
Sandbox lifecycle lock wrapper
src/lib/actions/sandbox/lifecycle/lock.ts, src/lib/actions/sandbox/lifecycle/lock.test.ts
Asynchronous and synchronous sandbox locks resolve Portable options, enforce the host fence, and serialize competing operations. Tests cover state selection, transitions, cleanup, and concurrency.

Test host-state authority through an observable connection outcome.

These assertions inspect mock calls and dependency options. They do not prove that connectSandbox uses host-scoped receipt authority or that the gateway-scoped path cannot execute. The harness supplies the authority behavior, so an alternate gateway-scoped fallback can remain untested.

Create host-state and gateway-state fixtures with different outcomes. Assert the public connectSandbox(..., { probeOnly: true }) result accepts only the host-state receipt. As per path instructions, tests must prefer observable public outcomes, and migration tests must prove that the superseded path cannot execute.

Reviewed commit 47463f929e673410ce05ce70fff3122605ff2fb5. The async consolidation correctly routes existing Hermes Portable receipts through the host fence before the receipt-owned lifecycle lock. After building the isolated checkout, focused lock, connect, cron-recovery, CLI, and onboarding validation passed; one CLI test timed out only in the parallel batch and passed immediately by itself.

I confirmed CodeRabbit’s unresolved finding at src/lib/actions/sandbox/lifecycle/lock.ts:50: the exported synchronous wrapper can be called directly by stopSandbox, in which case it acquires the Portable receipt lock without the host fence. The current CLI command receives that fence from the outer async wrapper, so this is non-blocking for the current command path. Please either restrict or assert the nested-only contract, or add equivalent direct-call fencing and a regression test before treating this helper as a standalone boundary.

Non-blocking sequencing note: #11482 materially overlaps the lock-root changes and also carries separate partial-start rollback behavior. Please preserve that rollback fix and make the intended landing order clear.

I am holding approval while three required exact E2E checks remain pending and the CodeRabbit thread remains unresolved.

Fail closed when a synchronous Portable lifecycle caller lacks the outer host fence.

@rsliter Thanks — addressed the blocking sync-lock point in 151a1e49800e6d98c380baccf56cf5e43783b45d.

  • Portable synchronous lifecycle acquisition now asserts that the current HOME-scoped host fence is already held, so a direct stopSandbox call fails closed instead of silently taking only the receipt lock.
  • Regression coverage verifies direct synchronous rejection and the valid nested host-fence path.
  • The non-default-port connect regression now crosses the public connectSandbox(..., { probeOnly: true }) boundary with a real valid host receipt plus an invalid gateway-scoped decoy receipt.
  • Focused validation: 240 tests passed across 11 files. typecheck:cli, growth guardrails (45 tests), and the full validate:pr gate also passed.
  • The CodeRabbit sync-lock thread is resolved by that commit.

I also compared this PR with #11482. The intended landing order is #11482 first, because it already carries the separately reviewed partial-start reconciliation/rollback. After #11482 lands, I will rebase this PR onto that result, resolve the overlapping CLI/connect/start/stop/Docker lock-root wiring in favor of the shared boundary here, and explicitly retain #11482's partial-start rollback and its regressions. This PR will not be merged ahead of #11482.

Thanks. I verified 151a1e49800e6d98c380baccf56cf5e43783b45d against the original review:

  • The synchronous Portable path now requires the HOME-scoped host fence, and direct unfenced calls fail closed.
  • The public probe regression now uses a real host receipt plus an invalid gateway-scoped decoy receipt.
  • Focused lock and connect validation passes 39 tests locally.
  • The CodeRabbit thread is resolved.

The #11482-first sequence is correct because #11482 carries the separate partial-start reconciliation and rollback. Please retain that behavior and its regressions during the rebase. I will re-review and approve the combined final commit after #11482 lands and this PR is rebased. Current CI and CodeRabbit checks on 151a1e4 are still running, so an approval now would not cover the intended landing revision.

Correction to my review: I withdraw the P2 comment about the host-only connect test. The gateway copy is intentionally invalid—its embedded policy source path remains bound to the host receipt directory, and copying also changes exact-file identity—so a gateway-scoped reader rejects it. No contributor action is required for that comment. The P1 asynchronous lock-domain transition blocker remains.

Do not mock lifecycle-lock options when using a real receipt.

When useRealPortableReceipt is true, the harness still mocks hermesPortableLifecycleLockOptions from the default { kind: "absent" } disposition. A real Hermes receipt can therefore be inspected while withPortableConnectSandboxLifecycleLock receives undefined and skips the lifecycle lock. Let the real resolver inspect the receipt, or require matching explicit test input.

Strengthen the host-fence ordering assertion.

setImmediate does not prove that the competing operation is blocked by the host fence. withMcpLifecycleLock performs asynchronous filesystem work after fence acquisition, so observed can remain empty even when the competing call passes through the fence concurrently. Record an event after transitionBlocked resolves and before the candidate flip, then assert that event precedes "portable" or "gateway" after both promises settle. Apply this to both transition tests.

Bound the in-process HOME-fence queue wait.

withPortableHostFence is reentrant, and the process-bound lock has bounded retries with stale-owner recovery. However, callers await the prior tails promise before they reach that lock. If one lifecycle operation hangs, later operations, including status, can wait indefinitely. Add cancellable timeout handling for the tails queue.

pass for OpenClaw, Hermes, and Deep Agents Code.

## Reason

The lifecycle lock change in #11490 requires synchronous callers to hold
the host fence. These two fixtures still called stop directly, causing
six failures. The [main CLI shard
failure](https://github.com/NVIDIA/NemoClaw/actions/runs/34549640442/job/103109915024)
reports the Podman cases.

## Changes

Wrap both fixtures' stop calls in the existing
`withCurrentPortableHostFence` and await their results. Preserve the
real lifecycle lock and all existing assertions. Production code is
unchanged.

The sibling stop unit tests already inject their lifecycle lock. The
public CLI already acquires the host fence. The missed provider fixtures
are now covered by the focused run below.

## Verification

- Before the fix: six failures across the two provider fixtures, all
reporting the missing HOME fence.
- `npx vitest run --project cli
src/lib/onboard/runtime-provider/podman.test.ts
src/lib/onboard/runtime-provider/runtime-provider-contract.test.ts
src/lib/actions/sandbox/lifecycle/lock.test.ts` — 102 tests passed after
the fix, including lock enforcement tests.
- `NODE_OPTIONS=--max-old-space-size=8192 npm run typecheck:cli` —
passed. Initial setup exhausted the default Node heap.
- `NODE_OPTIONS=--max-old-space-size=8192 npm run validate:pr` — passed
against canonical `74c628ef625177a0dc3a227accdc0379bfd1e252`.
- Normal pre-commit and commit-message hooks — passed.

The diff contains no secrets, API keys, or credentials.

## Review notes

Self-review of NVIDIA/NemoClaw commit
`4f8de45847007dbf34505e6c2ea3fd2ab6167281` covered both changed files
under the sensitive `src/lib/onboard/**` path. The review checked the
complete diff, sibling stop callers, and the host-fence enforcement
tests. No production control changes or remaining fixture failures were
found. Independent review is pending; this PR is a draft.

## Outcome

Station Express recognizes `GB300 DGX Station` as the same GB300
firmware family as `NVIDIA DGX Station GB300`. The existing PCI,
software, runtime, and identity-conflict requirements remain enforced.

## Reason

The post-#10914 retest exposed an order-dependent firmware pattern. The
updated base also exposed test-fixture assumptions that prevented CI
from validating this fix.

### Related issues

Fixes #11476
Refs #10914, #11133, #11490, and #11505

## Changes

- Extend the existing Bash and TypeScript patterns to accept either word
order, with optional `DGX` between `Station` and `GB300`.
- Execute the real installer/helper process boundary using temporary
firmware and PCI files. Extend the shared hardware corpus through
readiness admission and retain the rejection cases.
- Align two inherited provider tests with the HOME fence required by
#11490. They acquire the existing production fence before synchronous
stop operations; assertions and the production guard remain unchanged.
- Move Discord port readiness into its fixture helper and wait for a
complete canonical port record. A regression reproduces the former
empty-file-to-port-zero race.
- Wait for the legacy watcher fixture to announce readiness before
recording its PID, preserving the production ownership and exact-command
checks.

The production change remains one net added line in the two existing
Station classifiers. All other changes are regression tests or CI
fixtures. No supported platform, release profile, dependency, production
policy, workflow, or CI selector changed.

## Verification

Candidate: `52f04240b4d362b9aeb859f1ae4903554ff0f044`.

- Before the Station fix, eight regression cases failed across hardware
classification, installer routing, and readiness.
- Full installer prompt suite: 95 passed, one existing skip. Eight
real-helper positive/conflict/unsupported-profile cases passed again
after refreshing the base.
- Adversarial probes passed: 885 firmware variants, 16 cross-source
conflicts, 10 byte checks, 75 PCI combinations, 432 readiness
combinations, six direct-GPU policy checks, and no execution of shell
text in firmware values.
- Before the CI fixture repairs, six provider cases reproduced the
missing-HOME-fence error. The Discord port regression reproduced port
zero from an incomplete file.
- Six Station/CI fixture/lock/reliability suites: 216 tests passed with
the existing local `NEMOCLAW_TEST_TIMEOUT=15000` setting.
- Legacy watcher recovery suite: all five tests passed, including
rejection of a mismatched process identity.
- `npm run e2e:assertions:check` passed: 1,796 live assertions remain.
No assertion or CI gate was removed or waived.
- `NODE_OPTIONS=--max-old-space-size=8192 npm run build:cli` passed
before the final watcher-fixture edit;
`NODE_OPTIONS=--max-old-space-size=8192 npm run validate:pr` passed for
this commit against trusted main
`e05c08844bfb305c2d116f0cf0ea47ff0bae1587`. Secret scanning passed; the
diff contains no secrets, API keys, or credentials.

## Review notes

The maintainer-requested adversarial pass found no production defect.
The [nine-specialist
review](https://github.com/NVIDIA/NemoClaw/actions/runs/34543555082)
found one verification gap, addressed by the [real installer/helper
fixture](#11480 (comment)).
The other eight specialist reviews were clear. New CI and review results
apply to the current commit.

The inherited CI failure records are [CLI shard
2](https://github.com/NVIDIA/NemoClaw/actions/runs/34545632868/job/103097845847),
[CLI shard
5](https://github.com/NVIDIA/NemoClaw/actions/runs/34545632868/job/103097845811),
and [MCP
discovery](https://github.com/NVIDIA/NemoClaw/actions/runs/34545632959/job/103103473889).
The MCP artifacts showed a coherent bridge and a competing command
rejected at the outer HOME lock. Upstream #11505 now owns that case.
This PR uses its implementation and tests unchanged; the overlapping
PR-specific MCP matcher and tests were removed.

Physical Station retesting remains outstanding. [Aaron Erickson's
recorded direction](#11476)
authorizes admin merge after CI passes following disclosure of that
limitation. GitHub confirms `ericksoa` has admin permission.
