Colima exposes Docker through a persisted context and does not create /var/run/docker.sock. The OpenShell gateway reads only DOCKER_HOST, so onboarding failed with "Socket not found: /var/run/docker.sock". Select the local socket of a non-default current context when the Docker CLI default answers through it, unless /var/run/docker.sock already resolves to that socket.

On a host whose current Docker context is Colima, importing runner.ts now exports that context's socket as DOCKER_HOST. The build environment test sets DOCKER_CONTEXT but inherits DOCKER_HOST, and main now lets a nonblank DOCKER_HOST override DOCKER_CONTEXT, so the test fails on such a host once this branch is merged with main. It fails the same way on main when the shell exports DOCKER_HOST. Pin DOCKER_HOST to blank so the test checks only the variables it sets. Signed-off-by: Bowen Zhu <bowenzhu66@gmail.com>

The DNS action tests always passed a context inspector that found nothing, so none checked that a context detectDockerHost selects reaches the Docker commands. Add a case where the CLI default answers through the colima context and every Docker command runs against its socket. Without the context selection, it is the only test that fails.

## Outcome NemoClaw passes the Docker endpoint from the selected Colima context to OpenShell. When `DOCKER_HOST` and `DOCKER_CONTEXT` are unset, the gateway uses the same local Docker daemon that preflight found. ## Reason Docker can reach Colima through its saved context without `/var/run/docker.sock`. The shared Docker selector returned early when Docker answered. OpenShell then received no `DOCKER_HOST` and tried the absent default socket. ### Related issues Closes #12367. The diagnosis builds on [Bowen Zhu's earlier investigation](#12368). ## Changes - Read the selected context after Docker confirms that its selected daemon responds. - Export its supported local Unix endpoint through the existing shared Docker selector. - Use that result in subprocess environments and DNS repair commands. - Add behavior tests for selection, OpenShell subprocess environments, and DNS repair. - Isolate host context metadata in existing test fixtures. - Start command recorders after module initialization in six existing runner tests. - Resolve the gateway endpoint boundary from source in Vitest when generated files are absent. - Clarify when a saved local context resolves and when an explicit context still blocks the image build. - Describe saved-context selection in System Readiness, with the environment change limited to the CLI and its later child commands. Explicit `DOCKER_HOST` and `DOCKER_CONTEXT` retain their precedence. An inconclusive Docker probe retains the existing selection. Default contexts, unresolved metadata, remote endpoints, and default-socket aliases retain the existing selection. Unreachable-daemon discovery keeps its existing engine-conflict checks. The change transfers the already selected daemon endpoint; it does not select a different daemon after a successful probe. ## Verification Commit under review: `b104a94ea3d14d3419592afa370a2f5ae89d45d9`. The production fix is unchanged from `304a6a3794df03308c0daca26661595eaf62d0da`. - Pristine base `3619e535e2a63bd6e046e990a04710dda8db2443`: three behavior tests failed; 32 controls passed; none skipped. - The failures check the selected endpoint, the actual subprocess environment, and every DNS repair command. - Original production fix: 382 tests passed across 15 files; none failed or skipped. - `DOCKER_HOST=unix:///tmp/nemoclaw-unit-context.sock` with `sandbox-prebuild.test.ts`: 67 passed; none failed or skipped. - Original CLI build, plugin build, CLI typecheck, and publication hooks: passed. - OpenShell spawn coverage repair at `7aebd6c0598d614946b9743377cc1adf05b708d7`: 66 tests passed across three files; none failed or skipped. - Removing `DOCKER_HOST` only from the OpenShell spawn environment causes one failure; 15 controls pass. The production file bytes were restored. - Source-alias regression before this repair: the existing 16-case context suite has one real missing-module failure and 15 passing controls when all three generated output directories are absent. - After the alias repair: all 66 context, OpenShell adapter, and DNS tests pass with all three generated output directories absent; none fail or skip. - Both artifact-free runs restore the original generated directories in `finally`. No replacement output directory was created. - Repair `npm run typecheck:cli`: passed. - Repair `npm run docs`: zero errors. OpenClaw, Hermes, and Deep Agents generated pages were inspected. - Readiness reference correction: `npm run docs` reports zero errors. The four approved sentences were inspected in all three generated guide variants. - Unchanged plugin source-mode control at `42c302f0`: 18 tests pass across the gateway boundary and real runner suites with all three generated output directories absent; none fail or skip. - The plugin control restores the original generated directories in `finally`. No plugin alias or test change was made. - Repair whole-repository `npm run format:check`: passed on 5,494 files. - Repair ordinary Oxlint: zero warnings and zero errors on 5,229 files. The broad hook's separate type-aware Oxlint pass also passed. - All 18 repository checks, E2E phase-plan checks, source-shape checks, and local growth checks passed. - Canonical hadolint 2.14.0 passed for all Dockerfiles; its pinned checksum was verified. <details> <summary>Broader validation limits</summary> `npm run check` failed during its broad pre-commit stage. Its serialized all-file Oxfmt and ordinary Oxlint commands exceed the Linux shell argument limit inside npm's command wrapper (`spawn E2BIG`, errno -7). The same two failures occur on pristine `7aebd6c0598d614946b9743377cc1adf05b708d7` with both host npm 11.12.1 and canonical checksum-verified npm 12.0.2. The real whole-repository formatter and linter pass when their commands use a short glob or directory argument. The manual coverage stage did not run because pre-commit failed. The first broad run also used host hadolint 2.12.0; the exact canonical 2.14.0 binary passes without Dockerfile or policy changes. Fern reports two warnings: its remote redirect check requires authentication, and the unchanged light-theme accent has a 2.41:1 contrast ratio. The repository's local published-route check passes. No documentation token was supplied. </details> On 2026-10-28, Docker CLI 24.0.7 on Linux confirmed the context metadata command format. That check read local metadata and did not contact a Docker daemon. The behavior tests use injected Docker and filesystem responses. A real macOS Colima onboarding run passed on 2026-10-29 at `b104a94ea3d14d3419592afa370a2f5ae89d45d9`. [The run report](#13906 (comment)) records macOS 26.7.1, Colima 0.10.3, and OpenShell 0.0.116. The original redacted log is published in [part 1](#13906 (comment)) and [part 2](#13906 (comment)). The retrieved comment contents reproduce the original log and receipt hashes. - Both Docker selectors were absent at candidate entry, and `/var/run/docker.sock` was absent. - The saved `colima` context selected `unix://$HOME/.colima/default/docker.sock`. - Candidate PID `45643` launched native gateway PID `46187` with that Docker endpoint and no `DOCKER_CONTEXT`. - The native PID matched the runtime marker and PID file. - Onboarding and the non-repairing global `doctor --json` check both exited zero. - The named gateway was healthy, the QA registry binding matched, and all four postconditions passed. The run exercised fresh native gateway startup through the documented shipped-Dockerfile source-build route. It provides the manual record requested in [Rebecca's comment](#13906 (comment)). It does not establish managed-image catalog availability. ## Review notes Pre-publication source and documentation review of NVIDIA/NemoClaw at `b104a94ea3d14d3419592afa370a2f5ae89d45d9` covered `docs/reference/system-readiness.mdx` and found no blocker. The four approved sentences describe the existing source predicate and child-command environment. They preserve the explicit-selector, unreachable-probe, and inconclusive-probe guidance. The original review covered the seven-file production fix at `304a6a3794df03308c0daca26661595eaf62d0da`, including the sensitive path `src/lib/onboard/preflight-docker-persisted-context.test.ts`. Its OpenShell spawn assertions received a separate review before `7aebd6c0598d614946b9743377cc1adf05b708d7`. The source alias and troubleshooting correction received source and documentation review before `42c302f0cee3b667afae096fd65e58a991a014e6`. [Required source CI for `42c302f0`](https://github.com/NVIDIA/NemoClaw/actions/runs/40814970404) passed. The complete feedback batch for that commit was read, including all nine actual Advisor ledgers and reports. Eight Advisors were clear. The documentation finding about the System Readiness success branch is addressed by this follow-up. [Advisor run 40816879878](https://github.com/NVIDIA/NemoClaw/actions/runs/40816879878) failed while the live macOS Colima record was missing. [CodeRabbit's plugin-alias finding](#13906 (comment)) was checked with unchanged source-mode tests. Both existing plugin suites pass without generated files. Vite resolves their adjacent `.cjs` imports to the existing `.cts` source; the earlier CLI import named an absent `dist/shared` directory. [The executed evidence was posted in the review thread](#13906 (comment)). No plugin alias or test edit is needed. The real macOS Colima onboarding record is now available in [the run report](#13906 (comment)) and [the original log](#13906 (comment)). [Source CI for `b104a94e`](https://github.com/NVIDIA/NemoClaw/actions/runs/40819697101) and the [independent growth check](https://github.com/NVIDIA/NemoClaw/actions/runs/40820057462) passed. CodeRabbit reviewed the current System Readiness change and reported no actionable comments. All nine actual Advisor findings ledgers for this commit are clear. [Advisor run 40821678011](https://github.com/NVIDIA/NemoClaw/actions/runs/40821678011) failed before the real macOS Colima record was published. Its four runtime recommendations retain their recorded status. The new manual evidence is available for maintainer review. No approval or check waiver is claimed.

Outcome
On macOS with Colima and
DOCKER_HOSTunset,nemoclaw onboardstarts the OpenShell gateway instead of failing withSocket not found: /var/run/docker.sock.Reason
Colima exposes Docker through a persisted
colimacontext and does not create/var/run/docker.sock. The gateway reads onlyDOCKER_HOST. Since #8823,detectDockerHostkeeps a reachable CLI default without settingDOCKER_HOST, which undid the fix for #3503.Related issues
