# Verdict: pre-existing-fixes

## Status: PASS
**Completion Date**: 2026-06-15

## Summary
Fixed 4 pre-existing issues:
1. `_infer_state_from_artifacts` heuristic: SPEC-only now correctly returns `research` instead of `bug_find`; IMPLEMENTATION-only returns `bug_find` (implement done → next phase)
2. `cmd_validate_folder`: corrupted `.state` files now error instead of silently falling back to artifact inference
3. `upgrade.sh`: removed `|| true` so upgrade failures are visible; added python3 availability check; uses `git rev-parse --git-dir` for hooks directory (supports worktrees)
4. 6 new tests covering all fixes

## Findings
- All 206 tests pass
- No regressions introduced
- Heuristic fix aligns with existing `TestStateMachineAlignment` tests

## Score
+10
