# Bug Report: Inflight Upgrade Path

## Methodology
Reviewed upgrade.sh script, bootstrap .state from artifacts, version marker in config.md, and README/CHANGELOG updates.

## Acceptance Criteria
| # | Criterion | Result |
|---|-----------|--------|
| 1 | `status.py` bootstraps `.state` for tasks without it | ✅ |
| 2 | `upgrade.sh` scans all tasks and bootstraps missing `.state` | ✅ |
| 3 | `upgrade.sh` runs `--audit` and reports violations | ✅ |
| 4 | `upgrade.sh` produces human-readable summary | ✅ |
| 5 | Phase prompts work with or without `.state` | ✅ |
| 6 | `README.md` updated with new features | ✅ |
| 7 | `CHANGELOG.md` updated under `[unreleased]` | ✅ |
| 8 | Version marker added to `config.md` | ✅ |

## Findings
1. **Minor**: `migrate-project.sh` does not explicitly handle `.state` files that may already exist in migrated project task folders. The spec mentions "not delete `.state` files during migration" but the migration script currently skips task folders silently if they have `.state`. This is correct behavior but not explicitly tested.

## Verdict: PASS
