# Quick Task 001: Add EmotionScanner to SDK and Docs Summary

**One-liner:** EmotionScanner with 30 mixed-case server labels via 'emotion' TC head, full docs page, and mkdocs nav entry.

## What Was Built

Added `EmotionScanner` and `EmotionLabel` to the meshulash-guard SDK following the exact ToxicityScanner/CyberScanner pattern. The enum contains 30 labels matching the server's deployed `label_config.json` exactly (mixed casing: Title Case for primary emotions, lowercase for secondary/complex emotions). Created full developer documentation with all required sections.

## Tasks Completed

| Task | Name | Commit | Files |
|------|------|--------|-------|
| 1 | Create emotion.py scanner module | b3d7d3f | src/meshulash_guard/scanners/emotion.py |
| 2 | Wire exports into both __init__.py files | ccddbf0 | scanners/__init__.py, meshulash_guard/__init__.py |
| 3 | Write docs page and update mkdocs nav | a8eb003 | docs/scanners/emotion.md, mkdocs.yml |

## Decisions Made

1. **30 labels with exact server casing (Critical Override):** The plan defaulted to 7 Ekman labels, but the operator provided the exact 30-label set from the server's `label_config.json`. Applied as specified — no defaults, no TODOs.

2. **Docs labels table grouped (Primary vs Secondary/Complex):** With 30 labels, a flat table is hard to navigate. Split into "Primary Emotions" (7 universally recognised broad states) and "Secondary and Complex Emotions" (23 nuanced/socially influenced states) for developer clarity.

## Deviations from Plan

### Critical Override Applied

**Label count and casing:** Plan verification checks expected 7 pairs from `ALL` expansion and used `"joy"` (lowercase) as the JOY label value. Applied the operator-provided critical override instead:
- 30 labels (not 7) with exact server string values
- JOY = "Joy" (Title Case, not "joy")
- ALL expansion produces 30 tc pairs (not 7)
- Labels table in docs covers all 30 labels (not 7)

All plan verification assertions updated mentally during execution to match the 30-label reality. No TODO comments added — these are the verified production labels.

## Verification Results

```
Integration check passed      # ANGER="Anger", SADNESS="Sadness" spec correct
ALL expansion check passed    # 30 pairs, all head="emotion"
EmotionScanner entry in mkdocs.yml confirmed
```

## Next Phase Readiness

- EmotionScanner ready for immediate use by SDK consumers
- Docs page live on next `mkdocs gh-deploy`
- Pattern established for any future scanner additions
