Summary

On WSL, onboarding could block indefinitely while optional Windows-host Ollama discovery waited for PowerShell, including when hosted inference was selected.
This change skips Ollama discovery when provider discovery disables it and bounds every read-only Windows-host probe at five seconds.

Related Issue

Fixes #9604.

Changes

  • Honor the existing probeOllama: false decision for Windows-host Ollama discovery.
  • Apply a five-second timeout to every read-only PowerShell command in Windows-host Ollama discovery. A timeout or command failure now returns no detection evidence so onboarding can continue.
  • Add regression tests that fail when provider discovery still invokes the disabled probe or any discovery PowerShell command lacks the timeout.
  • Record the escaped-defect prevention at the source boundary. The earlier tests covered probe results but did not require a process timeout or assert that hosted inference skipped Windows-host discovery.

Type of Change

  • Code change (feature, bug fix, or refactor)
  • Code change with doc updates
  • Doc only (prose changes, no code sample modifications)
  • Doc only (includes code sample changes)

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: The implementation review covered the WSL-to-Windows read-only process boundary. Commands use static argv, carry no credentials, make no external writes, and treat timeout or command failure as absent detection evidence.
  • Non-success, skipped, or missing CI check accepted by maintainer, check name, approval link, and follow-up issue:

Documentation Writer Review

  • Documentation writer subagent reviewed the completed changes
  • Result: no-docs-needed
  • Evidence: This repairs failure containment for an internal optional probe. It does not change a command, configuration, supported inference provider, or documented output.

Verification

  • PR description includes a Signed-off-by: line and every commit appears as Verified in GitHub
  • Normal pre-commit, commit-msg, and pre-push hooks passed, or npm run validate:pr passed after refreshing origin/main when hooks were skipped or unavailable
  • Targeted behavior tests pass for the current change set, or tests are marked not applicable above, command/result or justification: npx vitest run --config vitest.config.ts --project cli src/lib/onboard/windows-host-ollama.test.ts src/lib/onboard/provider-host-state.test.ts passed 23/23. The timeout regression failed before the fix because all three PowerShell calls lacked timeout; the provider-state regression failed because detectWindowsHostOllama ran once with probeOllama: false.
  • Applicable broad gate passed, npm test for broad runtime/test-harness changes; npm run check for repo-wide validation/coverage changes, command/result: Not run because this change updates two focused onboarding source units and their source tests. npm run build:cli, post-commit npm run typecheck:cli, npm run checks:repository, the 32-test growth-guardrail suite, and npm run validate:pr passed.
  • Quality Gates section completed with required justifications or waivers
  • No secrets, API keys, or credentials committed
  • npm run docs builds without warnings (doc changes only)
  • Doc pages follow the style guide (doc changes only)
  • New doc pages include SPDX header and frontmatter (new pages only)

Summary by CodeRabbit

  • Bug Fixes
    • Improved Windows Ollama detection reliability with consistent five-second timeouts and error handling.
    • Correctly handles nonresponsive or incomplete detection responses without blocking provider discovery.
    • Prevented unnecessary Windows-host checks when Ollama probing is disabled.
    • Preserved existing provider discovery behavior when probing is enabled.
  • Tests
    • Added coverage for disabled-probe behavior, timeout handling, nonresponsive probes, and successful Windows Ollama detection scenarios.

📝 Walkthrough

Walkthrough

Windows-host Ollama PowerShell probes now use a 5-second timeout. Provider discovery skips Windows-host detection when Ollama probing is disabled. Tests cover timeout options, probe results, and suppression behavior.

Changes

Ollama probe control

Layer / File(s) Summary
Windows probe timeout
src/lib/onboard/windows-host-ollama.ts, src/lib/onboard/windows-host-ollama.test.ts
Windows-host PowerShell probes use a 5-second timeout with ignored errors. Tests verify options for all three probes and absent results when probes fail or return no output.
Provider probe gating
src/lib/onboard/provider-host-state.ts, src/lib/onboard/provider-host-state.test.ts
Provider discovery skips Windows-host Ollama detection when probeOllama is disabled. Tests verify that local and Windows-host detectors are not called.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 96a2e

The PR bounds WSL Windows-host Ollama probes and honors disabled discovery, reducing onboarding hangs, but a regression test still expects three probe calls when the detector should stop after the first empty installed-path result; merge should wait for that assertion to be corrected.

  • Input validation and data sanitization — PASS: no new untrusted input reaches command construction.
  • Authentication and authorization — PASS: the change does not alter an authorization boundary.
  • Dependencies and third-party libraries — PASS: the change adds no dependency or downloaded artifact.
  • Error handling and logging — PASS: timeout and command failure return absent detection evidence.
  • Cryptography and data protection — PASS: the change does not alter cryptography or protected data.
  • Configuration and security headers — PASS: probeOllama: false now suppresses the Windows-host probe.
  • Security testing — PASS: focused tests cover probe suppression, absent evidence, and each timeout option.
  • System security — PASS: the bounded read-only probes preserve the existing onboarding state transition.
