fix(onboard): detect Windows-host Ollama via process probe#3969
Merged
Conversation
`hasWindowsOllama` was probed only with `powershell.exe Get-Command ollama.exe`, which returns the binary path only when ollama.exe is on the calling user's PATH. Service-style installs (and other installers that do not update the user PATH) leave ollama.exe undiscoverable by Get-Command even when the daemon is running. Under the WSL2 repro in #3949 — Windows-host Ollama listening on 127.0.0.1:11434 only, host.docker.internal unresolvable from WSL — the PATH miss caused `hasWindowsOllama` to be false, so the inference menu showed "Install Ollama on Windows host (recommended)" instead of the "Restart Ollama on Windows host with 0.0.0.0 binding" variant. Fall back to a `Get-Process ollama` probe when the PATH lookup misses: a live ollama process is sufficient proof of installation, and the existing `winOllamaLoopbackOnly` block already uses Get-Process for PID and Get-NetTCPConnection for the bind address, so the loopback- only menu variant fires correctly once `hasWindowsOllama` is true. Add a regression test that asserts setupNim with NEMOCLAW_PROVIDER=start-windows-ollama is satisfied — and the loopback restart path is exercised — when Get-Command returns empty but Get-Process reports a live PID.

PR Review AdvisorRecommendation: blocked This is an automated advisory review. A human maintainer must make the final merge decision. Limitations: Review is based on trusted PR metadata, linked issue content, provided diff, and read-only repository inspection; no scripts, tests, package-manager commands, or network operations were executed by this advisor.; Issue #3949 has no issue comments in the provided context; acceptance coverage maps the issue body clauses only.; The E2E Advisor required wsl-e2e and it passed, but the advisor also identified a missing dedicated WSL Windows-host Ollama scenario that is not currently covered by existing E2E.; Interactive menu label rendering is inferred from setupNim state and label construction; the added tests exercise non-interactive provider selection rather than asserting the full literal menu output.; GitHub still reports mergeStateStatus=BLOCKED/reviewDecision=REVIEW_REQUIRED despite required CI passing; final merge readiness depends on clearing repository protection gates. Full advisor summaryPR Review AdvisorBase: The code change is focused and required WSL E2E passed for the head SHA, but the PR remains blocked by GitHub mergeStateStatus=BLOCKED/review requirements and should not be considered merge-ready until that gate clears.

- Around line 6100-6117: The new fallback probe that sets hasWindowsOllama using
runCapture and winOllamaPid should be extracted into a small helper function
(e.g., isWindowsOllamaRunning or probeWindowsOllama) placed under
src/lib/onboard/; replace the inline block in onboard.ts (the else branch that
calls runCapture and computes hasWindowsOllama) with a call to that helper so
onboard.ts has no net line growth. Ensure the helper exports a boolean-returning
function that performs the powershell Get-Process call (using runCapture) and is
imported/used by the existing code to assign hasWindowsOllama.

src/lib/onboard.tstest/onboard-selection.test.ts
Addresses three Codex findings on the original #3949 fix: * P1 (onboard-entrypoint-budget): move the WSL/Windows-host Ollama detection out of src/lib/onboard.ts and into a focused module at src/lib/onboard/windows-host-ollama.ts. setupNim now calls a single `detectWindowsHostOllama()` helper that returns `{ installed, installedPath, loopbackOnly }`. Net change to onboard.ts is now negative (-16), so the entrypoint budget check passes. * P2 (path recovery): when `Get-Command ollama.exe` misses, also capture the running ollama process's `.Path`, not just its PID. Recover both the install signal and the verified executable path from a single source. If `.Path` cannot be recovered (e.g. SYSTEM-owned service the user shell cannot inspect), the install is deliberately left flagged as not-installed so the restart path does not kill a daemon it cannot relaunch. * P2 (restart wiring): forward the recovered `installedPath` to `setupWindowsOllamaWith0000Binding` on the restart branch as well, not just on the install branch. This lets windows.ts target the verified binary directly via Start-Process instead of falling back to the calling shell's Windows PATH — which is the broken case #3949 surfaces. * Tighten the regression test to assert the exact shape of the setupCalls argument (announceStop:true + installedPath threaded through), and update the existing "uses the Windows-host start path when install-windows-ollama is requested but Ollama is already installed" assertion to match the new shape (installedPath now always plumbed when known). P3 (docs) is unaffected because the code keeps the "verified executable path" guarantee — the new fallback only adds a second source for that verification (Get-Process .Path) and refuses to treat the daemon as installed when neither source returns a path.

Reviewed for v0.0.49 feature freeze: scoped WSL/Windows-host Ollama detection fix; topper covers unreadable process Path with a conservative known-install fallback; checks and WSL E2E green.

Summary
On WSL2,
hasWindowsOllamawas determined solely by runningpowershell.exe Get-Command ollama.exe, which only returns a path whenollama.exeis on the calling user's PATH. Service-style installs (and any installer that does not update the user PATH) leave the binary undiscoverable byGet-Commandeven while the Windows-host Ollama daemon is running on127.0.0.1:11434.In that state, the inference menu offered "Install Ollama on Windows host (recommended)" instead of the "Restart Ollama on Windows host with 0.0.0.0 binding" variant that the bug report and the WSL2 Ollama test expect.
Fall back to a
Get-Process ollamaprobe whenGet-Commandreturns empty: a live ollama process is sufficient proof of installation. The existingwinOllamaLoopbackOnlyblock already usesGet-Processfor the PID andGet-NetTCPConnectionfor the listen address, so oncehasWindowsOllamais true the loopback-only menu variant fires correctly.Related Issue
