Outcome

The general staging Launchable E2E now succeeds only after brev exec <owned-workspace-id> true proves remote execution readiness. Failed probes remain bounded and retain only the final bounded, redacted diagnostic, while the existing control-plane checkpoint and confirmed cleanup remain intact.

Reason

The control-plane checkpoint merged in PR #11270 proves workspace creation but does not prove that Brev can execute a remote command. This is the first deferred capability slice in epic #11250.

Part of #11250

Changes

  • Add a distinct remote execution readiness phase after workspace creation and before the retained control-plane checkpoint.
  • Reuse BrevLaunchableFixture.waitForExec and its exact-owned-ID, bounded retry, redaction, and diagnostic contracts.
  • Add fast evidence that readiness succeeds after two failed probes and uses only the owned workspace ID.
  • Align workflow and artifact names with remote execution readiness and record the retry policy.
  • Keep runtime identity, onboarding, inference credentials, OpenClaw execution, and issue [Linux][Agent&Skills] openclaw agent CLI enters infinite tool-call loop on simple text requests — TUI returns correct response #9880 classification deferred.

Verification

  • npx vitest run --project e2e-support test/e2e/support/brev-launchable-fixture.test.ts — 29 tests passed.
  • npm run test:changed — 45 integration tests and 29 E2E-support tests passed.
  • npm run test:e2e-phases:check — 134 tests across 88 files passed semantic phase validation.
  • npm run test:projects:check — 2,632 candidates have exact Vitest project membership.
  • npm run e2e:assertions:check — assertion ratchet passed with 1,800 direct live assertions.
  • npm run checks:repository — repository checks passed.
  • actionlint .github/workflows/staging-launchable-full.yaml — passed.
  • node --experimental-strip-types --no-warnings scripts/checks/e2e-mock-parity.mts --base origin/main --head HEAD — mock/live parity passed.
  • Normal commit and push hooks passed after local build prerequisites were restored.
  • The diff contains no secrets, API keys, or credentials.

Review notes

This changes a credentialed, billable remote-execution workflow. Brev credentials remain confined to the workflow-specific HOME, command probes persist no raw attempt artifacts, diagnostics are bounded and redacted before persistence or error reporting, operations remain bound to the persisted owned ID, and cleanup still requires two confirmed absence observations.

📝 Walkthrough

Walkthrough

The staging Launchable E2E flow verifies remote execution readiness, records readiness evidence, and classifies successful targets accordingly. The workflow uses longer timeouts and updated artifact naming. Fixture coverage validates readiness after failed probes.

Changes

Remote execution readiness

Layer / File(s) Summary
Readiness probe validation
test/e2e/support/brev-launchable-fixture.test.ts
The fixture test validates readiness after two failed probes and a successful third probe. It checks command arguments and the absence of failure evidence.
Live readiness flow
test/e2e/RETRY_INVENTORY.md, test/e2e/live/issue-9880-staging-launchable.test.ts
The retry inventory documents the readiness operation. The live test waits for readiness, writes remoteExecutionReady: true, and uses the remote-execution-ready classification.
Workflow execution and evidence
.github/workflows/staging-launchable-full.yaml
The workflow uses remote execution naming, increases job and readiness timeouts, and updates the evidence artifact prefix.

Manual Brev comparison for run 34483204500

This is a command-level comparison, not a same-instance or verified same-Launchable reproduction.

Original CI observation

  • Run: https://github.com/NVIDIA/NemoClaw/actions/runs/34483204500
  • Trusted controller SHA: b11d1e214e385b6f7a5208637cbae9b1c7698a0b
  • Candidate SHA: 36dbf94701e78ba208d5416b7339581aa92bd846
  • Launchable ID: env-3I2w334slP4GKSce9kKK0hGerjJ
  • Created workspace: nclaw-e2e-34483204500-1 (d78kq9odi), n2d-standard-4
  • Creation accepted: 2026-09-10T14:32:42.952Z
  • Brev reported the workspace ready: 2026-09-10T14:35:14.928Z
  • The 900-second SSH-readiness loop began: 2026-09-10T14:35:14.929Z

The trusted controller made these underlying calls:

  1. timeout <up-to-60>s brev refresh initially and after every fifth SSH attempt.
  2. timeout <up-to-15>s ssh -T -o BatchMode=yes -o ConnectTimeout=10 -o ConnectionAttempts=1 -o NumberOfPasswordPrompts=0 -o RequestTTY=no -o LogLevel=ERROR nclaw-e2e-34483204500-1 true.
  3. After the readiness deadline, a diagnostic timeout <up-to-5>s brev exec nclaw-e2e-34483204500-1 true, followed by the same direct-SSH command under the remaining diagnostic budget.

Final CI results:

  • Last brev refresh: status 124 at 2026-09-10T14:50:14.530Z; retained diagnostic refreshing brev....
  • Last readiness direct SSH: status 255 at 2026-09-10T14:50:14.532Z; no retained diagnostic output.
  • Diagnostic brev exec: status 124 at 2026-09-10T14:50:19.582Z; retained diagnostic Connection failed, checking instance status....
  • Diagnostic direct SSH: status 255 at 2026-09-10T14:50:19.584Z; no retained diagnostic output.
  • Workspace cleanup verified d78kq9odi absent at 2026-09-10T14:52:33.658Z.

Local comparison

I reused an existing staging-named workspace rather than creating a duplicate:

  • Workspace: nemoclaw-staging-8b26a1 (cjk7yz8n1), n2d-standard-4
  • At 2026-09-10T18:41:43Z, Brev v0.6.334 inventory reported RUNNING, build_status=COMPLETED, shell_status=READY, and health_status=HEALTHY.
  • The CLI was the exact CI-pinned Brev v0.6.334 Darwin arm64 release; its archive matched official SHA-256 134450ea78085c9793cbdc663c8adc901996b3f81c71632374426ee340c6276d.

I then ran the same underlying commands with the same per-call budgets:

  1. brev refresh, 60-second budget: started 2026-09-10T18:40:42.380Z, ended 2026-09-10T18:41:00.302Z, exit 0, did not time out. It did report get network info: deadline_exceeded / get environment: deadline_exceeded and legacy SSH fallback for several workspaces, including cjk7yz8n1.
  2. Direct SSH by workspace name with the CI options, 15-second budget: started 2026-09-10T18:41:00.352Z, ended 2026-09-10T18:41:00.586Z, exit 255, failed but did not consume the timeout budget.
  3. brev exec nemoclaw-staging-8b26a1 true, 5-second budget: started 2026-09-10T18:41:00.632Z, ended 2026-09-10T18:41:05.646Z, terminated at the budget, timed out, after Connection failed, checking instance status....

Common observation: brev exec timed out and direct SSH failed while Brev inventory reported the workspace healthy. Difference: CI brev refresh itself timed out, while the local refresh completed with exit 0 after emitting backend deadline warnings.

Important limitation: the local workspace name suggests a staging deployment, but because it is inaccessible I could not verify its provision receipt or prove it came from Launchable env-3I2w334slP4GKSce9kKK0hGerjJ. Therefore this supports the same Brev access-path failure signature, but it does not prove the original fresh-provisioning failure was reproduced end to end.

Classify non-retryable readiness failures before retrying.

BrevLaunchableFixture.waitForExec retries every failed brev exec result because it checks only result.exitCode === 0. Permanent command or authorization failures can consume the full 15-minute readiness window. Retry only timeout and classified external failures, fail immediately for other result classes, and update test/e2e/RETRY_INVENTORY.md to match.
