# Session: Learn Monitor End-to-End Verification

**Date:** January 26, 2026
**Duration:** ~15 minutes
**Objective:** Verify Microsoft Learn Documentation Monitor works end-to-end

---

## Summary

Successfully verified the Learn Monitor system works correctly from baseline establishment through change detection and report generation. Merged PR #2 to establish the production baseline.

---

## Actions Taken

### 1. Merged PR #2

```bash
gh pr merge 2 --merge --delete-branch
```

- **PR Title:** "Learn Monitor: Microsoft Learn Documentation Update (7)"
- **Merged At:** 2026-01-26T00:57:30Z
- **Content:** `data/learn-monitor-state.json` (1733 lines, 191 URLs)

### 2. Pulled Latest to Local

```bash
git pull origin main
```

### 3. Verified Monitor Against Production Baseline

```bash
python3 scripts/learn_monitor.py --limit 5
```

**Result:** "Meaningful changes: 0" - correctly detected no changes

### 4. Simulated Content Change

Injected fake old content into one URL's state to simulate Microsoft updating a page:

```python
state['urls'][first_url]['normalized_content'] = 'OUTDATED CONTENT'
state['urls'][first_url]['content_hash'] = 'sha256:old_hash'
```

### 5. Verified Change Detection

```bash
python3 scripts/learn_monitor.py --limit 5
```

**Result:**
- "CHANGED: meaningful (UI element names)"
- Exit code 1 (triggers CI)
- Report generated: `reports/learn-changes/learn-changes-2026-01-26.md`

### 6. Verified Report Content

Report correctly showed:
- Priority: HIGH
- Affected controls: 2.1, 2.2, 2.15, 1.8
- Full diff of content changes

### 7. Restored State File

```bash
git checkout data/learn-monitor-state.json
rm reports/learn-changes/learn-changes-2026-01-26.md
```

## Verification Results

| Test | Expected | Actual | Status |
|------|----------|--------|--------|
| Baseline in main | 191 URLs, valid hashes | 191 URLs, valid hashes | PASS |
| No-change detection | "Meaningful changes: 0" | "Meaningful changes: 0" | PASS |
| Change detection | "CHANGED: meaningful" | "CHANGED: meaningful" | PASS |
| Report generation | Report with diff | Report with diff | PASS |
| Exit code for CI | 1 on changes | 1 on changes | PASS |
| Affected controls | Listed in report | Listed (2.1, 2.2, 2.15, 1.8) | PASS |

## Full Monitor Run (191 URLs)

After verification, ran a full check against all 191 URLs:

```bash
python3 scripts/learn_monitor.py
```

**Result:**
- Meaningful changes: 0
- Minor changes: 0
- Redirects: 53
- Errors: 0

**Conclusion:** No documentation updates needed. Microsoft has not changed any monitored pages since the baseline was captured (~2 hours prior).
