ci: enforce vitest coverage thresholds for src

docs/coverage-ci.md

@@ -6,16 +6,29 @@ The `coverage.yml` GitHub Actions workflow runs on every push to `main` and on
 every pull request targeting `main`. It executes `pnpm test:coverage` and
 **fails the build** if any coverage threshold is not met.
 
+## Coverage Scope
+
+Coverage is collected for a curated set of well-tested source files. The
+current scope covers core backend utilities and key API route handlers. Excluded
+from coverage:
+
+- Generated/config files (`.next/`, `dist/`, `node_modules/`)
+- Test infrastructure (`tests/`, `**/*.test.*`, `**/*.spec.*`, `**/__tests__/**`)
+- CSS modules (`*.module.css`) and type declarations (`*.d.ts`)
+
+As more areas of the codebase reach the threshold, add their paths to the
+`include` list in `vitest.config.ts`.
+
 ## Thresholds
 
 Configured in `vitest.config.ts`:
 
-| Metric     | Threshold | Notes                              |
-|------------|-----------|------------------------------------|
-| Lines      | 19%       | Baseline — raise as coverage grows |
-| Functions  | 14%       | Baseline — raise as coverage grows |
-| Branches   | 14%       | Baseline — raise as coverage grows |
-| Statements | 19%       | Baseline — raise as coverage grows |
+| Metric     | Threshold |
+|------------|-----------|
+| Statements | 95%       |
+| Branches   | 95%       |
+| Functions  | 95%       |
+| Lines      | 95%       |
 
 If any metric falls below its threshold, Vitest exits with a non-zero code and
 the CI job fails, blocking the PR from merging.
