## Scope Drift Check

**Status:** `CLEAN` | `DRIFT DETECTED` | `REQUIREMENTS MISSING` | `DRIFT + MISSING`

### Intent Summary
Sources checked: TODOS.md ✓ | PR description ✗ | Commit messages (N commits) ✓ | STATE.md ✗
- [Summarise the stated intent in 2-3 bullet points]

### Delivered Summary
- N files changed across M directories
- [Summarise what the diff actually does in 2-3 bullet points]

### Scope Creep (if any)
| File/Directory | Why it looks unrelated | Severity |
|---------------|----------------------|----------|
| `path/to/file` | Not mentioned in any intent source | Low/Medium/High |

### Missing Requirements (if any)
| Requirement | Source | Evidence |
|------------|--------|----------|
| [Requirement text] | TODOS.md line N | No matching file changes found |

### Recommendation
- [One-line recommendation: "Clean — proceed to review" or "N items drifted, M requirements missing — review with awareness"]

After detecting Dev context and subtype:
1. Run scope drift analysis
2. Display the structured report
3. Proceed to Step 2 (visual indicators) regardless of result

## Scope Drift Check
**Status:** CLEAN

### Intent Summary
Sources: TODOS.md ✓ | Commit messages (4 commits) ✓
- Add retry logic to provider dispatch
- Handle 429 rate limit responses

### Delivered Summary
- 3 files changed: provider-router.sh, lib/resilience.sh, tests/unit/test-resilience.sh
- Added error classification and exponential backoff

### Recommendation
Clean — proceed to review.

## Scope Drift Check
**Status:** DRIFT DETECTED

### Intent Summary
Sources: TODOS.md ✓ | PR description ✓ | Commit messages (7 commits) ✓
- Fix login page CSS alignment
- Add loading spinner to submit button

### Delivered Summary
- 8 files changed across 4 directories
- Fixed CSS alignment, added spinner, AND refactored auth module, updated 3 unrelated test fixtures

### Scope Creep
| File/Directory | Why it looks unrelated | Severity |
|---------------|----------------------|----------|
| `src/auth/oauth.ts` | Auth refactor not in any intent source | Medium |
| `tests/fixtures/users.json` | Test fixture updates unrelated to CSS/spinner | Low |
| `package.json` | Dependency bump not mentioned | Low |

### Recommendation
3 items drifted — review with awareness. Consider splitting auth refactor into a separate PR.
