# HOLE Fonts - Session Memory
**Date:** 2025-12-29
**Session:** v0.2 Development & Testing

---

## What We Just Accomplished

### 1. Built Complete v0.2 Intelligence System
- Created metadata extraction using FontTools (no external APIs required)
- Built duplicate detection with strict matching rules
- Implemented search and filtering capabilities
- Integrated Adobe Typekit API for optional enrichment

### 2. Fixed Critical Duplicate Detection Bug
**User feedback:** System was finding 1,860 false positives
- Example: "UniversNext731BasicHeavyItalic" matched to "UniversNext431BasicItalic"
- Problem: Different weights (900 vs 400) being matched as duplicates

**Fix implemented:**
- Weight must match EXACTLY
- Italic status must match EXACTLY
- Width must match EXACTLY
- Monotype unique IDs must match (6-digit numbers in filename)
- Name similarity threshold raised to 95% (from 80%)

**Result:** 1,860 false positives → 101 real duplicates ✓

### 3. Completed Full Library Scan
- Location: `/Volumes/HOLE-RAID-DRIVE/HOLE-Assets/HOLE-Fonts/`
- Total fonts: 11,047 (across TTF, OTF, WOFF2 formats)
- Variable fonts: 324
- Font families: 1,651
- Database created: `HOLE-Fonts-RAID-Database.json` (8.1 MB)

### 4. Ran Typekit Enrichment
- API Key: `459aa874c56344b9c2f44b3a5edde401dc918fca`
- Enriched: 28 fonts (0.25% coverage - most fonts not in Typekit database)
- Output: `HOLE-Fonts-RAID-Enriched.json` (8.1 MB)

### 5. Tested Search Functionality
- Searched for "AgencyFB Regular weight"
- Found 30 files (10 variants × 3 formats)
- Counted unique variants in WOFF2: 27 unique AgencyFB fonts
- Breakdown: 5 width families × 5 weights + 2 bonus styles

## User Preferences & Decisions

### Architecture Decisions
1. **External organization tool:** Use FontBase (not building custom solution)
2. **Simple structure:** 3-folder layout (TTF/, OTF/, WOFF2/) - no complex trees
3. **Python, not Rust:** User rejected experimental Rust rewrite, wants immediate production use
4. **Local storage:** iCloud too slow for scanning, use RAID drive instead

### Quality Standards
- Duplicate detection must be STRICT (no false positives)
- Monotype unique IDs are trustworthy
- Different weights/italic/widths are NEVER duplicates
- Name similarity must be 95%+ to consider as duplicate

### Versioning Strategy
- **Software versions:** Separate from library versions
- **Current:** HOLE Fonts Converter v0.2.0
- **Library:** HOLE Foundation Font Library v0.1.0 (from earlier release)

## Critical Code Snippets

### Duplicate Detection Logic (hole_fonts/dedup.py:186-261)
```python
def _calculate_match_confidence(self, font1, font2):
    # STRICT RULES - must match EXACTLY
    if font1.weight != font2.weight:
        return 0.0, "Different weights"

    if font1.italic != font2.italic:
        return 0.0, "Different italic status"

    if font1.width != font2.width:
        return 0.0, "Different width"

    # Extract Monotype unique IDs (pattern: FontName-123456.ttf)
    id1 = self._extract_unique_id(font1.filename)
    id2 = self._extract_unique_id(font2.filename)

    if id1 and id2 and id1 != id2:
        return 0.0, f"Different unique IDs ({id1} vs {id2})"

    # Name must be 95%+ similar (raised from 80%)
    name_sim = self._name_similarity(font1, font2)
    if name_sim < 0.95:
        return 0.0, "Name not similar enough"

    # Build confidence score
    confidence = name_sim
    # ... (additional checks for glyph count)

    return confidence, reason
```

### Search Example
```python
from hole_fonts.search import FontSearch, SearchCriteria
from hole_fonts.metadata import FontDatabase

db = FontDatabase('database.json')
db.load()

search = FontSearch(db)
criteria = SearchCriteria(
    family='AgencyFB',
    weight_min=400,
    weight_max=400,
    format='woff2'
)
results = search.search(criteria)
```

## Testing Results

### Test 1: Scan Command (Input/ directory)
- ✅ Scanned 4,241 fonts successfully
- ✅ Created test-scan.json (3.1 MB)
- ✅ Duplicate report generated (101 high-confidence matches)
- ✅ No false positives after strict matching fix

### Test 2: Full RAID Scan
- ✅ Scanned 11,047 fonts in ~5 minutes
- ✅ Performance: 10-20 fonts/second
- ✅ Database: 8.1 MB
- ✅ All formats detected: TTF, OTF, WOFF2

### Test 3: Typekit Enrichment
- ✅ Processed all 11,047 fonts
- ✅ Enriched 28 fonts with designer/foundry data
- ✅ Rate limiting working (0.5s between requests)
- ✅ LRU caching preventing duplicate API calls

### Test 4: Search Functionality
- ✅ Found all AgencyFB Regular weight fonts (30 files)
- ✅ Counted unique variants in WOFF2 (27 unique fonts)

## User Questions Answered This Session

1. **"How is it progressing?"** - Scan was running, provided progress updates
2. **"What are we using to scan these fonts?"** - Clarified: FontTools (not Typekit)
3. **"Search for AgencyFB regular weight"** - Found 30 files, 10 unique variants
4. **"How many unique AgencyFB fonts (WOFF2 only)?"** - 27 unique variants

---

## Important Context for Next Session

### If continuing work:
1. All databases are in project root directory
2. Package may need reinstall: `uv sync --reinstall-package hole-fonts`
3. Typekit API key is saved in this file
4. RAID drive fonts are fastest to scan
5. iCloud fonts are slow (avoid for large scans)

### If creating release:
1. Update version number first
2. Build wheel before committing
3. Tag after pushing to main
4. Include databases as example artifacts (or links to them)

### If user reports issues:
1. Check if package needs reinstall
2. Verify database path exists
3. For enrichment: use `enrich_fonts.py` script (CLI has bug)
4. For slow scans: check if path is on iCloud/network volume
