<execution_protocol>
Follow these steps in order. Signal done only after the Definition of Done checklist passes.

1. **Startup**: Verify environment per Session Startup. If baseline tests fail, signal error.

2. **Read & orient**: Read all input files. Run \`git log --oneline -10\` to check recent changes.

3. **Write failing tests (RED)**: Write tests for the expected behavior. Run them — they must fail. If they pass before implementation, they're testing existing state; rewrite until they genuinely fail.

4. **Implement (GREEN)**: Minimum code to pass tests. Choose one approach and execute — don't deliberate between alternatives.

5. **Verify green**: Run the full relevant test suite, linter, and type checker. If anything fails, fix your code — do not proceed with broken checks. If a pre-existing test fails, fix your code, not the test (unless the task explicitly changes expected behavior).

6. **Update docs**: If your changes affect behavior documented in \`docs/\`, update the relevant doc file. When renaming or moving files, grep docs for stale references.

7. **Commit**: Stage specific files, commit using Conventional Commits format, update progress file.

8. **Iterate**: For multi-part tasks, repeat 3-7 per part. Each cycle produces a commit.

If the task has no testable behavior (config, docs), skip steps 3 and 5 but note why in your progress file.

${TEST_INTEGRITY}

<anti_patterns>
- **Mega-commits**: Commit after each logical unit, not one giant commit at the end.
- **Silent reinterpretation**: Task says X, do X. Don't substitute Y because you think it's better.
- **Hard-coded solutions**: Implement general logic, not code that only works for specific test inputs.
- **Debug artifacts**: Remove all \`console.log\`, debug statements, and temporary instrumentation before committing.
- **Spinning on failures**: If a fix attempt fails 3 times, stop and signal "questions" or "error" with what you tried. Don't loop indefinitely.
</anti_patterns>

<scope_rules>
- Do exactly what the task says — no unrelated fixes, refactors, or improvements. Other agents may own those files.
- If you need to modify a file another task owns, coordinate via \`cw ask\` first.
- Touching 7+ files? You're probably overscoping. Re-read the task.
- When renaming or moving files, grep for stale imports and references to the old path. Fix them in the same commit.

<definition_of_done>
Before writing signal.json with status "done":

- [ ] All tests pass (full relevant suite)
- [ ] Linter and type checker pass (no new errors)
- [ ] Relevant docs updated (if behavior changed)
- [ ] No uncommitted changes
- [ ] No debug statements or temporary instrumentation left in code
- [ ] Progress file updated
- [ ] Implemented exactly what the task asked — no more, no less

If any item fails, fix it. If unfixable, signal "error" explaining what's wrong.
