## Static Data Format Overview

The Ponomar PWA uses a JSON-based static data system organized by language. All liturgical data is pre-converted from XML sources and structured for efficient serving and client-side rendering.

### Core Principles
- **Language-based organization**: Each language has its own directory under `static/data/`
- **JSON storage**: All data stored as JSON files for easy parsing
- **Date-based routing**: Calendar data organized by Julian calendar dates (MM-DD format)
- **CId-based identification**: Canonical Identifiers (CIds) uniquely identify saints and feasts
- **Prefix-based file routing**: Lives files routed by CId prefix (01-12 → month files)

### Supported Languages
- `en` — English
- `cu` — Church Slavonic
- `ru` — Russian
- `el` — Greek (includes `el/mono` for monochord)
- `fr` — French
- `zh` — Chinese (includes `zh/Hans` and `zh/Hant` for Simplified/Traditional)
- `shared` — Cross-language resources

```

### File Types
- `*-bundle.json` — Calendar mapping files
- `lives/*.json` — Saint lives bundles
- `menaion/*.json` — Daily liturgical entries
- `services/*.json` — Service templates and logic
- `calendar/*.json` — Calendar calculations and metadata

---

## Data Models & Schemas

### Bundle Entry (menaion-bundle.json)
```json
{
  "01-01": [
    { "id": "010101" },
    { "id": "772426" },
    { "id": "010102" }
  ]
}
```
**Structure**: Object keyed by date `MM-DD` with array of entries, each containing only `"id"` field with CId value.

### Life Entry (lives/*.json)
```json
{
  "772426": {
    "name": {
      "nominative": "Прп. Сильвестра Печерского (XII)",
      "short": "Прп. Сильвестра Печерского"
    },
    "life": {
      "id": "minei-0101-772426",
      "copyright": "Четьи-Минеи свт. Димитрия Ростовского",
      "text": "<p>Преподобный отец наш Сильвестр...</p>"
    }
  }
}
```
**Structure**: Object keyed by CId (string), each containing:
- `name` object with case variants (`nominative`, `short`, `genitive`, etc.)
- `life` object (optional) with `id`, `copyright`, and `text` fields

### Calendar Entry
```json
{
  "pascha": { "year": 2025, "date": "04-20" },
  "fixed": [
    { "date": "01-01", "rank": 5, "celebration": "Circumcision" }
  ]
}
```
**Structure**: Contains movable feast calculations and fixed calendar data.

### Service Template Entry
```json
{
  "ROYALHOURS": {
    "0": {
      "text": "In the name of the Father...",
      "type": "0"
    }
  }
}
```
**Structure**: Hierarchical service structure with text nodes and conditional logic.

---

## File Routing Rules

### Lives File Routing
Lives bundles are routed based on CId prefix:

| CId Pattern | Target File | Examples |
|-------------|--------------|----------|
| `01XX-01ZZ` | `01.json` | `010101`, `014567` |
| `02XX-02ZZ` | `02.json` | `023456`, `027890` |
| ... | ... | ... |
| `12XX-12ZZ` | `12.json` | `123456`, `127890` |
| Other CIds | `misc/{n}.json` | `772426→misc/7.json`, `373→misc/3.json` |

**Examples:**
- `010101` → `01.json`
- `1253` → `12.json`  
- `772426` → `misc/7.json`
- `373` → `misc/3.json`

### Bundle File Naming
- Main bundle: `menaion-bundle.json` (per language)
- Language overrides: `{lang}-menaion-bundle.json`
- No prefix-based routing for bundles (single file per language)

---

## Data Components Breakdown

### Menaion Bundles
**Purpose**: Authoritative date → CId mapping for calendar rendering

**Structure**: Date-keyed JSON with arrays of CIds
```json
{
  "01-01": [{ "id": "010101" }, { "id": "772426" }],
  "01-02": [{ "id": "010201" }, { "id": "772455" }]
}
```

**Coverage**: 366 Julian calendar days × multiple entries per day
**File Size**: ~50-100KB per language
**Usage**: Calendar view determines which saints to display on each day

### Lives Bundles
**Purpose**: Saint biographies and lives for enrichment

**Structure**: CId-keyed JSON with name variants and optional life text
```json
{
  "772426": {
    "name": {
      "nominative": "Прп. Сильвестра Печерского (XII)",
      "short": "Прп. Сильвестра Печерского"
    },
    "life": {
      "id": "minei-0101-772426",
      "copyright": "Четьи-Минеи свт. Димитрия Ростовского",
      "text": "<p>Complete life text in HTML...</p>"
    }
  }
}
```

**Coverage**: 3046 total CIds, 1203 with life.text enriched

## Enrichment Process

### Overview
The enrichment process fills empty `life.text` fields in ru/lives bundles using Chetyi-Minei (St. Dimitri of Rostov) hagiographic texts.

### Source Preparation: Chetyi-Minei Import

**`convert-minei.ts`** — Converts Chetyi-Minei EPUB to date-keyed JSON

**Input Layout (extracted EPUB):**
```
extracted-epub/
├── index_split_000.xhtml through index_split_9999.xhtml
├── toc.ncx
└── content.opf
```

**Process:**
1. Parse day files sequentially
2. Extract headings: `h2` for dates (`"Память 1 января"`), `h3` for chapter titles
3. Extract paragraphs: `<p class="paragraph1">` for content
4. Collect footnotes from `<a title="...">` anchors
5. Append notes as "Примечания:" block
6. Apply heading date corrections (e.g., `calibre_toc_10023` → `01-27`)
7. Build output structure: `{ "MM-DD": [{ title, html }] }`

**Usage:**
```bash
npx tsx scripts/convert-minei.ts <extracted-epub-dir> [output.json]
```

**Output:** `scripts/output/minei.json` (gitignored, ~33MB)

### Enrichment Pipeline

**`enrich-lives.ts`** — Fuzzy-matches minei titles to CId names and fills empty lives

**Inputs:**
- `scripts/output/minei.json` — Source lives by date (MM-DD)
- `static/data/cu/menaion-bundle.json` — Authoritative date→CId map
- `static/data/ru/lives/*.json` — Target bundles for enrichment

**Matching Strategy:**
1. **Tokenization**: Split titles into tokens, filter ROLE_WORDS
2. **Dice Coefficient**: Calculate similarity over token sets
3. **Status Classification**:
   - `already-filled` — Target already has `life.text` → skip
   - `auto` — Score ≥ 0.6, empty target → write
   - `review` — Score 0.35–0.6 → manual review
   - `unmatched` — Score < 0.35 or no candidates → unmatched

**Manual Overrides:**
```typescript
const MANUAL_FIXES: Record<string, string> = {
  '02-02|сказание о сретении': '373',
  '03-24|воспоминание о чуде': '822',
  // 214 entries total
}
```
Key format: `{date}|{distinctive substring}` → CId

**Collision Handling:** Multiple sources map to same CId
- First source: writes `life.html` directly (no heading)
- Subsequent sources: append `<p><b>{title}</b></p>{html}`

**File Routing:**
```typescript
function bundleFileForCid(cid: string): string {
  return /^(0[1-9]|1[0-2])\d+/.test(cid) 
    ? `${cid.substring(0, 2)}.json` 
    : `misc/${cid.charAt(0)}.json`;
}
```

**Usage:**
```bash
# Dry run: report only
npx tsx scripts/enrich-lives.ts

# Limit to one month
npx tsx scripts/enrich-lives.ts --month 01

# Apply changes
npx tsx scripts/enrich-lives.ts --write

# Apply changes for specific month
npx tsx scripts/enrich-lives.ts --write --month 01
```

**Output:** `scripts/output/lives-match-report.json` with match status per source

### Workflow Example

**Phase 1: Source Preparation**
```bash
npx tsx scripts/convert-minei.ts ~/Downloads/chetyi-minei-epub/
# Output: scripts/output/minei.json
```

**Phase 2: Dry Run Analysis**
```bash
npx tsx scripts/enrich-lives.ts
# Shows: Auto-applied: 184, needs review: 127, unmatched: 94
# Review: scripts/output/lives-match-report.json
```

**Phase 3: Manual Review & Fixes**
- Analyze `review` entries in report
- Add MANUAL_FIXES for problematic matches
- Re-run until `review` count acceptable

**Phase 4: Write & Validate**
```bash
npx tsx scripts/enrich-lives.ts --write
# Shows: Wrote 7 updated bundle(s)
npx tsx scripts/validate-data.ts
npx tsc --noEmit
npm run build
```

**Phase 5: Commit**
```bash
git add scripts/enrich-lives.ts scripts/output/lives-match-report.json static/data/ru/lives/
git commit -m "enrich 121 more ru lives with Chetyi-Minei texts"
```

### Quality Controls

**Collision Verification:** Check multi-chapter entries have correct headings
```bash
python3 -c "
import json, re
misc = json.load(open('static/data/ru/lives/misc/4.json'))
for cid in ['493', '1674', '257401']:  # Known collision targets
    text = misc[cid]['life']['text']
    headings = re.findall(r'<b>([^<]+)</b>', text)
    print(f'{cid}: {len(headings)} chapters - {headings}')
"
```

**Coverage Tracking:** Monitor enrichment progress
```bash
python3 -c "
import json, glob, os
total = has = 0
for fp in glob.glob('static/data/ru/lives/*.json'):
    data = json.load(open(fp))
    for cid, entry in data.items():
        total += 1
        if isinstance(entry.get('life'), dict) and entry.get('life', {}).get('text'):
            has += 1
print(f'Coverage: {has}/{total} ({has*100//total}%) lives with text')
"
```

## Quality Assurance Workflow

### Pre-Commit Checklist

1. **Data Validation**
```bash
npx tsx scripts/validate-data.ts
# Expected: "All files valid!" or specific error count
```

2. **Type Safety**
```bash
npm run check  # or npx tsc --noEmit
# Expected: No TypeScript errors
```

3. **Build Verification**
```bash
npm run build
# Expected: Successful build with bundle sizes
```

4. **Functional Testing**
```bash
npm run dev
# Manual test: Calendar view, saint detail pages, lives display
```

### Continuous Monitoring

**Automated Checks:**
- File count validation (should be 274 files)
- JSON parseability (all data files)
- Required field presence (nominative, life.text for enriched entries)
- CId consistency (same CId should have same name across languages)

**Issue Detection:**
- Corrupted JSON files → parse errors in validate-data.ts
- Missing required fields → validation warnings
- Type mismatches → TypeScript errors
- Build failures → invalid data structures

### Issue Resolution

**Common Validation Errors:**
1. **"Missing nominative"** — Name object lacks nominative case
   - **Solution**: Add `name.nominative` field to affected entries

2. **"Failed to parse"** — Corrupted JSON file
   - **Solution**: Re-run conversion or fix JSON syntax

3. **"Rank should be 0-8"** — Invalid rank value
   - **Solution**: Normalize rank to range 0-8

4. **Build bundle size changes** — Unexpected file size increases
   - **Solution**: Check for duplicate or malformed content

## Common Issues & Solutions

### OCR Artifacts in Minei Texts

**Problem:** Chetyi-Minei conversion produces OCR issues like:
- Latin characters in Russian text (`Taиcии` instead of `Таисии`)
- Footnote markers `[1]` in body text
- Erratic punctuation `[1]` in titles

**Solution:**
- Keep OCR artifacts as-is (part of source text)
- Manual fixes use exact OCR substrings for matching
- Examples: `'02-15|onissima, odnogo iz lika'` → `'450'`

### Homonym Resolution on Same Date

**Problem:** Multiple saints share similar names on same date

**Examples:**
- 03-24: Иаков исповедник (68501) vs other Иаков entries
- 02-22: Варадат vs Фалассий (both map to 493)
- 09-03: Анфим, Аристион, Василиса on same date

**Solution:**
- Use distinctive substrings in MANUAL_FIXES
- Ensure uniqueness per date (verify with verification script)
- For collisions: both sources map to same CId (append behavior)

### Cross-Date Narratives

**Problem:** Some minei chapters are narratives not tied to a specific feast

**Examples:**
- 02-02: "Сказание о Сретении Господнем" (presentation narrative)
- 03-24: "Воспоминание о чуде в Печерском монастыре" (miracle story)
- 08-28: "Память святой праведной Анны" (prophetess Anna)

**Solution:**
- Identify appropriate CId for the saint/event
- Map with MANUAL_FIXES even if not on same date (though current pipeline is date-based)
- For entries with no appropriate CId: remain unmatched

### Bundle Mis-Mappings

**Problem:** Some CIds are listed on wrong calendar dates

**Example:** 
- 868 Иаков Боровицкий listed under 05-22, actual feast 10-23

**Solution:**
- Manually correct menaion-bundle.json
- Move CIds from incorrect date to correct date
- Verify with calendar sources and tradition

### File Routing Edge Cases

**Problem:** Ambiguous routing for CIds at boundaries

**Edge Cases:**
- `00` prefixes → misc/{first-digit}.json (not 00.json)
- `99` prefixes → misc/{first-digit}.json (not 09.json)
- Non-numeric CIds → misc/{first-digit}.json

**Solution:** 
```typescript
/^(0[1-9]|1[0-2])\d+/.test(cid) // Match only 01-12 followed by digits
```

### Multi-Chapter Collision Display

**Problem:** When multiple sources append to same CId, first chapter lacks heading

**Behavior:**
- First source: writes `life.html` directly (no title)
- Subsequent sources: append `<p><b>{title}</b></p>{html}`
- Result: First chapter unheaded, others clearly marked

**Acceptable Trade-off:** Consistent with all single-chapter lives (which have no heading)
