# Adversarial Bug Report: fix-test-plan-phase-mapping

## Attack Vectors Tested
1. **Task with both TEST_PLAN.md and IMPLEMENTATION.md**: IMPLEMENTATION.md is checked first in both status.py and task.py, so it correctly maps to `code_review` — no regression
2. **Task with TEST_PLAN.md only**: Maps to `test_design` — correct
3. **Task with TEST_PLAN.md and CODE_REVIEW.md**: CODE_REVIEW.md checked first → `bug_find` — correct
4. **Case sensitivity of filenames**: Artifact check uses exact string match — `test_plan.md` (lowercase) would not match `TEST_PLAN.md` — this is existing behavior, not a new issue

## Findings
No bugs found.

## Verdict: PASS
