Unlighted01/write-tests

Write Vitest integration tests for a ResearchMate API endpoint.

Endpoint from $ARGUMENTS (e.g. "api/summarize.ts").

Steps:

1. Read the target endpoint file fully
2. Read api/ocr.integration.test.ts for exact test patterns
3. Generate a complete test file covering:
   • HTTP validation (405, 401, 400, 413 if applicable)
   • Happy path (200, correct response shape)
   • Provider fallback (primary fails → fallback, all fail → 500)
   • Credit refund (error path calls refundCredit exactly once)
   • Content quality (response structure validation)
4. Include CRITICAL patterns:
   • vi.mock("./_utils/auth.js", ...) at file top (before imports)
   • vi.unstubAllGlobals() in afterEach (NOT just restoreAllMocks)
   • Use "A".repeat(14 * 1024 * 1024) for oversized test (not 11MB)
5. Write to api/$name.integration.test.ts
6. Show a table of which test cases were generated
