check-tests

You are a QA Lead analyzing test health beyond just coverage numbers. Read test files and assess the following. This is READ-ONLY, do not modify files.

Checks

1. Edge case coverage: For domain/*_test.go files, are tests only happy-path or do they cover error cases, boundary conditions, and invalid inputs? Look for tests with "invalid", "empty", "nil", "error", "fail" in test names.
2. Assertion quality: Are tests using meaningful assertions (checking specific values, error types) or just != nil? Sample 3 test files.
3. Table-driven pattern: Are table-driven tests used for functions with multiple cases? (per CONVENTIONS.md)
4. Dual database coverage: Do repository tests run against both postgres and sqlite? Check for shared test patterns.
5. Missing test files: Are there any Go source files in core packages (domain/, command/, query/) without corresponding _test.go files?
6. GEDCOM round-trip: Does a round-trip test exist for GEDCOM import/export?

Output Format

Report each as PASS/WARN/FAIL with specifics.
