fix(doctor): warn when only half the inference route resolves

[udsy19]

Summary

nemoclaw <name> doctor treated its Inference Route check as satisfied when
either half of the (provider, model) pair was known, so a half-resolved route
printed [ok] Route: unknown / nvidia/nemotron — a status that contradicts the
detail on the same line — and, because the recovery hint hangs off the same flag,
the ok branch also withheld the one line telling the operator how to recover.
After this change a route reads ok only when both halves resolved, and every
other shape keeps its warn and its hint.

Fixes #9435

Changes

• src/lib/actions/sandbox/doctor-inference.ts — inferenceRouteCheck now requires
  both halves of the route pair (|| → &&). One line changed, no lines added.
  This matches every other route-usability predicate in the repository
  (registry-entry-view.ts:27, start.ts:136, status-snapshot.ts:513/525/533/588,
  gateway-route-compatibility.ts:95) and removes a self-contradiction inside this
  same file, where collectProviderHealthDiagnostics (:188-191) already reports
  provider route is unknown on a single unknown half.
• src/lib/actions/sandbox/doctor-inference.test.ts — extends the file's existing
  it.each scaffolding with a two-row table covering both half-resolved shapes. No
  new helper, fixture, import, if, or loop.

No new configuration, fallback, compatibility path, or supported surface. No
abstraction added.

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: requesting maintainer review; the change is a single boolean operator in a diagnostic classifier and adds no new code path
• Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

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 — npm run validate:pr exit 0 with origin/main refreshed to the branch base; Codebase growth guardrails, Repository checks, Source-shape test budget, Oxfmt, Oxlint fixes, and TypeScript (CLI) all Passed
• Targeted behavior tests pass for the current change set — npx vitest run --project cli src/lib/actions/sandbox/doctor-inference.test.ts → 20 passed. With the production line reverted the two new rows fail (status: "ok", hint: undefined versus the expected warn + guidance) and the other 18 cases still pass, so the test pins the fixed behavior and no pre-existing case depended on the old predicate.
• Applicable broad gate passed — not applicable; this is neither a broad runtime/test-harness change nor a repo-wide validation/coverage change
• 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)

📝 Walkthrough

Walkthrough

The test suite adds parameterized coverage for inference routes with an unknown provider or model. It verifies that collectInferenceChecks emits a warning Route diagnostic and recovery hint when provider health returns no result.

Changes

Inference route validation

Layer / File(s)	Summary
Partial route warning coverage src/lib/actions/sandbox/doctor-inference.test.ts	Parameterized tests cover unresolved provider/model combinations and assert the warning status and recovery guidance.

Estimated code review effort: 2 (Simple) | ~5 minutes

Merge Risk: ⚪ Minimal · up to 8e0c1

The route diagnostic now warns when either provider or model is unresolved and preserves recovery guidance; no actionable merge-blocking risk remains beyond normal checks and review.

[prekshivyas]

Addressed the active review thread in de27a21.

The partial-route regression now finds the Route diagnostic by label and asserts the exact warning status and recovery guidance instead of relying on array position or accepting any string.

Validation: 20 focused doctor tests passed; npm run typecheck:cli passed; npm run validate:pr passed. The commit is signed and DCO-certified.

[prekshivyas]

Approved at exact head de27a21 after the requested label-based diagnostic and exact recovery-hint assertion were added. Focused tests, typecheck, and full PR validation pass.

LOC Reduction / Codebase Simplicity Review

Why changes are requested

After the base refresh, this PR duplicates coverage that is already present on the target branch.

src/lib/actions/sandbox/doctor-inference.test.ts:35-54 already table-drives the complete route matrix. It includes both half-resolved routes and asserts the exact Route status, detail, and recovery hint. The current PR diff adds a second 15-line table at lines 94-107 for the same two rows and the same warning and hint.

The production fix is already present on the refreshed base, so the PR now adds only overlapping test setup and assertions.

Refactor direction

Delete the second table. If label-based lookup is still useful, update the existing table in place from checks[0] to checks.find((check) => check.label === "Route") and keep its exact object assertion.

This reduces the current PR to one replacement line. If that lookup change does not add a required contract, the PR can close because the refreshed base already contains the behavior and coverage.

Expected result

One route matrix owns the complete known, half-known, and unknown cases. The test keeps exact recovery-guidance coverage without a second fixture and assertion block.

[apurvvkumaria]

Thanks for the contribution. Closing this PR as superseded by #9473, which merged the incomplete-route condition and a four-case matrix covering both half-resolved routes with the warning and recovery guidance; the current PR diff now adds only duplicate coverage.
