Test Review

Review test adequacy for changed code. For large changes spanning many files or test suites, fan out fast-tier readers per logical area — one per package or suite — each returning gap candidates. Synthesize and filter in this session.

Scope

1. Coverage gaps

• new exported behavior with a plausible failure mode — name the bug a missing test would catch
• new branches or error paths without coverage
• changed behavior that existing tests do not exercise
• renamed concepts or protocol terms without tests that cover the new form and guard the old form if needed

2. Edge cases

• boundary conditions (empty inputs, missing files, null/undefined)
• error recovery paths (command not found, parse failures)
• configuration variants the code handles
