Reviewed exact head fbad030. The repair now distinguishes confirmed stopped, running, and unavailable Hermes gateway observations; retries only confirmed stopped state; preserves downstream gateway error reporting; and includes focused regression coverage. No remaining code or security blocker found.

Assert probe outcomes instead of shell text.
These assertions inspect only sshCommands[0]. They do not prove that a completed non-200/401 response produces false or that a curl transport failure produces null. Exercise the recovery probe through its injected executor and assert these observable results.
As per path instructions, review tests for behavioral confidence rather than implementation lock-in.

<!-- markdownlint-disable MD041 --> ## Outcome Hermes recovery now waits for the gateway process to become observably running after NemoClaw starts a stopped sandbox. A transient indeterminate process observation no longer advances immediately to gateway verification and causes `sandbox start` or `connect --probe-only` to fail. ## Reason Live Docker/Hermes testing of the fix from #11922 showed that the first post-start process observation can be indeterminate while the same container continues starting normally. The prior predicate accepted that state, so recovery reached gateway inspection too early and failed. ### Related issues Follow-up to #11922 ## Changes - Add a shared, bounded Hermes gateway-process settlement check that accepts only an observed running process. - Apply the settlement check after `sandbox start` and when `connect --probe-only` starts a stopped ordinary Hermes sandbox. - Preserve immediate behavior for already-running, paused, unresolved, failed-start, portable, OpenClaw, and terminal-agent paths. - Add coverage for transient indeterminate observations, persistent non-running observations, successful recovery, and paths that must not receive post-start grace. ## Verification - `./node_modules/.bin/vitest run --project cli src/lib/actions/sandbox/start.test.ts src/lib/actions/sandbox/connect-probe-observe.test.ts` — PASS, 2 files and 32 tests. - `node --max-old-space-size=8192 node_modules/typescript/bin/tsc -p tsconfig.cli.json` — PASS after CLI and plugin builds. - Normal `pre-commit`, `commit-msg`, and `pre-push` hooks — PASS. - Live Brev Docker/Hermes reproduction on merged #11933 commit `b259c14c33f20f18a8ae2c995aaeb5e8242b14d9` — installation, created state, status, managed inference, route isolation, and official cleanup passed; explicit start and stop-to-probe recovery failed on the same running container after the transient process observation, confirming this change's target boundary. - Diff review — no secrets, API keys, credentials, or private endpoint data included. ## Review notes This is a narrow lifecycle correction. It does not change credentials, network policy, routes, privileges, container identity, or external mutation controls. A PR-head live Docker/Hermes recovery run remains the final real-runtime validation. --- Signed-off-by: Senthil Ravichandran <senthilr@nvidia.com> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Bug Fixes** - Improved sandbox recovery after starting a stopped container by waiting for its gateway process to become available. - Added retry handling for gateway startup checks to improve recovery reliability. - Sandbox connections now report a clear process-stage failure when the gateway does not become available, rather than incorrectly signaling readiness. - Preserved existing behavior for already-running containers and terminal error scenarios. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Rebecca Sliter <571084+rsliter@users.noreply.github.com> Co-authored-by: Rebecca Sliter <571084+rsliter@users.noreply.github.com>

## Outcome Hermes `sandbox start` and `connect --probe-only` now finish after a stopped sandbox recovers. Both commands return success after readiness publication and managed inference succeed on the same container. ## Reason PR #11933 restored a Hermes call to `/usr/local/bin/nemoclaw-gateway-control`. PR #11792 removed that controller from managed images. The missing command made gateway observation return an unknown result while the gateway and inference route were healthy. ### Related issues Relates to #10638. Follow-up to #11933. ## Changes - Use the recorded OpenShell gateway and its native in-sandbox HTTP health check for Hermes and OpenClaw. - Let the Hermes post-start process check settle bounded unknown results before readiness publication. - Retry only the existing transient inference statuses for Hermes after start. Authentication and other terminal failures still fail immediately. - Cover recovered, persistent, and unchanged OpenClaw behavior in focused tests. ## Verification - `./node_modules/.bin/vitest run --project cli src/lib/actions/sandbox/launch-readiness-gateway-health.test.ts src/lib/actions/sandbox/start.test.ts src/lib/actions/sandbox/connect-probe-observe.test.ts src/lib/actions/sandbox/connect-hermes-accepted-readiness.test.ts` — passed, 4 files and 104 tests. - `NODE_OPTIONS=--max-old-space-size=8192 npm run typecheck:cli` — passed. - `npm run build:cli` — passed. - Commit hooks with `NEMOCLAW_GROWTH_BASE_REF=upstream/main` — passed. - Normal upstream push hooks — publication validation and CLI TypeScript checks passed. - Brev Ubuntu 22.04 Docker/Hermes test from main `d9c33770772f06264b3a45b52fe9efc6d83aa34f` — `stop` then `start` returned 0 in 15.175 seconds; `stop` then `connect --probe-only` returned 0 in 14.134 seconds. Both runs kept container `cb0cf4f854a9aa8f97a2126acb2e331effece0f8af47bea48a38151d836069ef` and passed readiness publication and managed inference. - `git diff --check origin/main...HEAD` — passed. - The diff contains no secrets, API keys, or credentials. ## Review notes The live check replaced only the two compiled modules under test. It restored their original SHA-256 values after validation and left the retained sandbox running for PR-commit validation. --- Signed-off-by: Senthil Ravichandran <senthilr@nvidia.com> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Bug Fixes** - Improved Hermes sandbox startup reliability by retrying temporary gateway and inference failures. - Startup checks now wait briefly for transient service recovery before reporting failure. - Gateway readiness is validated through its native health endpoint for more accurate status reporting. - Added bounded retry behavior so startup fails safely when readiness cannot be confirmed. - Preserved single-attempt verification for OpenClaw and other non-Hermes agents. - Hermes status checks now use direct health verification instead of legacy gateway-control checks. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Senthil Ravichandran <senthilr@nvidia.com>

Outcome
nemoclaw sandbox startnow waits for a just-started Hermes agent gateway to settle before it checks gateway health. A transient stopped-process observation no longer makes recovery fail while the existing container becomes usable.Reason
Two Docker/Hermes recovery runs on v0.0.126 started the same stopped container, then exited after about 2.4 seconds because the agent gateway still appeared stopped. An immediate status check reported the same container as
Ready, with the gateway present and inference healthy.Related issues
Fixes #11922

Verification
npx vitest run --project cli src/lib/actions/sandbox/start.test.ts— 9 tests passed on commit433e1c6a26d06870a499d26451253a56329c8a60.0d35b9bffda9ab984f973970473ee78fffa7ab26— stop completed in 1.636 seconds; start completed in 19.448 seconds after two settlement retries; the same container reachedReady; gateway and authenticated inference checks passed.git diff --check origin/main...HEAD— passed.Review notes
The retry accepts only an explicit running result. An unavailable process observation fails immediately. Gateway health, host-forward, and inference checks remain unchanged after settlement.
