fix(onboard): verify Windows Ollama Docker reachability

[rsliter]

Summary

Express onboarding on WSL now distinguishes a Windows-host Ollama daemon that WSL can reach from one that Docker containers can reach. When Docker cannot reach the daemon, onboarding uses the existing Windows restart path to persist OLLAMA_HOST=0.0.0.0:11434, restart Ollama, and verify a valid Ollama response from Docker before model setup. Explicit and interactive ollama selections use the same reachability gate.

Related Issue

Fixes #10100

Changes

• Probe Windows-host Ollama from Docker even when WSL resolves it directly.
• Offer and select the existing Windows restart action when the daemon is installed and running but is not Docker-reachable.
• Route explicit and interactive ollama selections through the restart action unless Docker confirms Windows-host reachability.
• Keep the restart action available when the running daemon proves that Ollama is installed but PowerShell cannot locate its executable.
• Accept post-restart readiness only when Docker receives a valid Ollama /api/tags response.
• Preserve direct reuse when Docker already reaches the Windows daemon, and fail closed when reachability is not proven.
• Consolidate Windows-host flow coverage in one focused public-entrypoint suite.

Quality Gates

• Tests added or updated for changed behavior
• Existing tests cover changed behavior; justification:
• Tests not applicable; justification:
• Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging)
• Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: Fixed Docker probe arguments carry no credentials. Invalid or missing reachability evidence cannot become success. The existing bounded restart path owns the host mutation and postcondition verification.
• Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

Exact-commit CI on 1151555c6a53b9c89490ce56368b164656dcdeb6 passed direct startup for OpenClaw, Hermes, and Deep Agents Code, exact all-agent activation, both OpenClaw MCP discovery passes, staging, image, and E2E checks; the remaining roster-balance failure is inherited from main.

Walkthrough

Windows-host Ollama discovery now validates Docker reachability. Provider selection reuses the daemon only when reachable and routes unreachable supported states to start-windows-ollama. Readiness validation now requires a valid tags response.

Route eligible Windows-host requests through start-windows-ollama, or return the
established failure before direct selection; ensure canUseWindowsHostOllama
remains the authoritative capability check. Add a createSetupNim regression test
proving the public entrypoint uses the new path and the old direct path cannot

Blockers

PRA-1 Blocker — Reject unreachable Windows-host Ollama in the interactive flow

• Location: src/lib/onboard/setup-nim-flow.ts:1003
• Category: security
• Problem: Interactive selection of `ollama` can bypass the Docker-context reachability check for a Windows-host Ollama daemon.
• Impact: The flow can record and use a sandbox inference route to `host.docker.internal` although Docker has not proved that it can reach the daemon. Onboarding then fails after it records provider state instead of restarting the daemon with the required binding or returning to selection.
• Fix: Apply the Windows-host reachability rule before the interactive running-daemon path. When the daemon is unreachable, select `start-windows-ollama` when that option exists; otherwise return to provider selection with an error.
• Verification: Read `createSetupNim` with `isWindowsHostOllama: true`, `ollamaRunning: true`, and `windowsOllamaReachable: false`. Confirm that an interactive `ollama` choice cannot call `handleRunningOllamaSelection`.
• Test coverage: Add an interactive flow test for that host state. Assert that the flow calls `handleWindowsHostOllamaSelection` with `start-windows-ollama`, or returns to selection, and never calls `handleRunningOllamaSelection`.
• Evidence: `src/lib/onboard/provider-menu.ts:100-111` keeps the running `ollama` menu entry and adds `start-windows-ollama` when `isWindowsHostOllama` is true and `windowsOllamaReachable` is false. `src/lib/onboard/setup-nim-flow.ts:1000-1015` sends an interactive `ollama` selection to `handleSelectedOllama` without requiring `windowsOllamaReachable`. `src/lib/onboard/provider-selection.ts:168-185` redirects a non-interactive `ollama` request in the same state to `start-windows-ollama`, proving the intended reachability contract.

PRA-2 Blocker — Validate Windows-host Ollama restart readiness responses

• Location: src/lib/inference/ollama/windows.ts:122
• Category: security
• Problem: The Windows-host restart readiness probe treats every nonempty Docker response as a live Ollama daemon, while host detection validates the `/api/tags` response format.
• Impact: A proxy page, stale responder, or arbitrary nonempty body can make onboarding set `host.docker.internal` and report recovery although the sandbox cannot use an Ollama API. Retry and diagnosis then operate on false readiness.
• Fix: Make `awaitWindowsOllamaReady` use the existing `isValidOllamaTagsResponseBody` validator before it sets the resolved host or returns success.
• Verification: Read `awaitWindowsOllamaReady` with a nonempty invalid Docker body, such as HTML. Confirm that the function cannot return success or set the resolved host.
• Test coverage: Extend `src/lib/inference/ollama/windows.test.ts` with a nonempty invalid response. Assert that readiness continues to retry, does not set the host, and does not report success. Retain the valid `{ "models": [] }` case.
• Evidence: `src/lib/onboard/provider-host-state.ts:196-202` accepts Docker reachability only when `isValidOllamaTagsResponseBody(body)` succeeds. `src/lib/inference/ollama/windows.ts:122-132` returns success for `if (probe)` and sets the resolved host. `src/lib/onboard/setup-nim-ollama.ts:226-243` calls `awaitWindowsOllamaReady` after install, and `src/lib/inference/ollama/windows.ts:176` calls it after restart.

PRA-3 Blocker — Keep Windows-host flow tests in the existing test owner

• Location: src/lib/onboard/setup-nim-flow-windows-ollama.test.ts:8
• Category: architecture
• Problem: The PR adds a separate one-test `createSetupNim` suite although the existing flow suite already owns adjacent Windows-host Ollama cases.
• Impact: One flow contract now has two test-file owners. Maintainers must locate and update both files when Windows-host selection changes.
• Fix: Move the explicit Docker-unreachable dispatch test into `setup-nim-flow.test.ts` near the related Windows-host cases, then delete `setup-nim-flow-windows-ollama.test.ts`. Preserve its host-state setup and both handler-dispatch assertions.
• Verification: Compare the new test with the Windows-host cases in `setup-nim-flow.test.ts`. Confirm that both test the same `createSetupNim` flow owner and that moving the test preserves distinct dispatch coverage.
• Test coverage: The existing moved test is the regression evidence: retain the case where `windowsOllamaReachable` is false and assert the Windows-host handler runs while the running-daemon handler does not.
• Evidence: `src/lib/onboard/setup-nim-flow-windows-ollama.test.ts:8-68` contains one `createSetupNim` Windows-host dispatch test. `src/lib/onboard/setup-nim-flow.test.ts:347-450` already contains reachable and mirrored Windows-host Ollama flow tests under the existing `createSetupNim` suite.

Recommended refactoring

Implementation guidance; a fix with equal or lower complexity is acceptable.

• PRA-3: Remove Delete `src/lib/onboard/setup-nim-flow-windows-ollama.test.ts` after moving its single test into the existing flow suite.; use Use the existing `src/lib/onboard/setup-nim-flow.test.ts` `createSetupNim` suite as the single owner for Windows-host flow dispatch tests.. Net: -8 lines. Keep: Retain the Docker-unreachable host state and the assertions that prevent the running-daemon path from bypassing the restart handler.
