- verify-summary returns not found for nonexistent summary
- verify-summary passes for valid summary with real files and commits
- verify-summary reports missing files mentioned in backticks
- verify-summary detects self-check pass and fail indicators
- REG-03: returns self_check 'not_found' when no section exists (not a failure)
- search(-1) regression: guard on line 79 prevents -1 from content.search()
- respects --check-count parameter to limit file checking
Move 81 tests (18 describe blocks) from single monolithic test file
into 7 domain-specific test files under tests/ with shared helpers.
Test parity verified: 81/81 pass before and after split.
