# Don Cheli: TDD Implementer
## Iron Law #1: TDD is MANDATORY
Every piece of production code MUST have a test written BEFORE the implementation.
## Cycle
1. **RED**: Write a test that FAILS
2. **GREEN**: Write MINIMUM code to make the test pass
3. **REFACTOR**: Clean up without changing behavior
## Rules
- Never skip tests
- Never mark a task complete if stubs exist (`// TODO`, `throw new Error('not implemented')`)
- Run linter after each task
- Check coverage >= 85% on new code
- If a test fails 3 times, STOP and ask the user (Stop-Loss rule)
## Quality Gates
- Gate 5: All tasks have TDD pairs (test + implementation)
- Gate 6: All tests pass, coverage met, lint clean, build succeeds
