src/lib/onboard/windows-host-ollama.test.ts (1)
108-113: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAdd a behavioral listener-ownership test.
The positive case returns loopback addresses for any listener probe, while the negative case returns no listener output. Neither distinguishes an Ollama-owned listener from an unrelated loopback listener. The source-text assertion is the only ownership-specific check. Add controlled ownership cases at the Windows boundary and remove this assertion.

Exact-head review of a77fc1220df00be4ed324a0b4b76df17aceaa726.
P0
- None.
P1
- Two line-level findings are attached.
The new a77fc122 commit fixes the stale cached-route cleanup bypass by revalidating the persisted Ollama route before model unload. All 11 commits are verified. Required CI and the Advisor rerun are still in progress, and there is not yet an exact-head CodeRabbit review object. I will re-review the next SHA.

Blocking findings:
- One code-local operability blocker is attached inline.
- Approval also requires merging current main so the required
E2E / PR Gateruns against the current base boundary.
Reviewed commit e902b74. The new protected-resume selection is consistent with the revalidated Windows route; product scope and all nine security categories remain clear. Focused verification passed 166 provider recovery and onboarding tests plus git diff --check. CodeRabbit completed successfully; Advisor run 33925631016 produced the inline timeout finding.

Reviewed commit 8e8122b. The prior runtime-authority blocker is resolved; focused verification passed 39/39 Windows Ollama tests, and the main-sync merge had no production-code overlap. CodeRabbit and all nine Advisor specialists completed; this Security specialist finding is the only material remaining code blocker.

All prior blockers are resolved on 44d42e7: Windows-host requests revalidate the current runtime, Docker context, loopback-only listener, reachability, and hostile Host-header protection before execution; process probes are bounded; and proxy routing derives from the accepted route authority. The main sync preserved the reviewed behavior. Focused verification passed 247/247 tests with clean diff validation; all 69 current checks, CodeRabbit, all nine Advisor specialists, DCO, and verification for all 52 commits are clear.

Outcome
Windows-host Ollama is now reused from WSL only when Windows reports a loopback-only listener, Docker Desktop can reach
/api/tags, and Ollama returns403for an untrusted HTTPHostvalue. Windows install and repair actions persistOLLAMA_HOST=127.0.0.1:11434; unprotected direct and mirrored routes fail closed to WSL-local Ollama.Reason
The existing Windows/WSL path persisted
OLLAMA_HOST=0.0.0.0:11434, exposing Ollama's unauthenticated API and disabling the loopback-only Host-header validation that blocks same-host DNS rebinding. Restricting inbound network access does not address that browser-to-loopback attack path.Changes
403probe during both discovery and readiness checks.127.0.0.1identity, so generic Ollama selection cannot bypass repair.Verification
npm run validate:prpassed, including repository checks, growth guardrails, commitlint, shellcheck, secret scanning, Markdown lint, and CLI TypeScript.npm run docspassed with 0 errors and 2 non-blocking Fern warnings.Review notes
