+Unit tests must be requirement-driven, not implementation-driven.
+Coverage requirements:
+- Happy path: all normal use cases from requirements
+- Edge cases: boundary values, empty inputs, max limits
+- Error handling: invalid inputs, failure scenarios, permission errors
+- State transitions: if stateful, cover all valid state changes

+Process:
+1. Extract test scenarios from requirements BEFORE writing tests
+2. Each requirement maps to ≥1 test case
+3. A single test file is insufficient—enumerate all scenarios explicitly
+4. Run tests to verify; if any scenario fails, fix before declaring done

+Reject "wrote a unit test" as completion—demand "all requirement scenarios covered and passing."
