Project Context for AI Agents

Quick Project Overview

Ponomar is a Progressive Web App for Orthodox Church calendar, liturgical services, and Bible readings.

• Technology: TypeScript + Vite + Tailwind CSS v4
• Data: JSON-based liturgical data organized by language (en, cu, ru)
• Architecture: Client-side PWA with static JSON data, no backend database
• Core Functionality: Calendar display, service assembly, Bible reading, saint lives, astronomy

Key Architectural Patterns

Data Organization

• Language-based structure: static/data/{lang}/ (en, cu, ru)
• Bundle system: menaion-bundles, lives bundles (month-prefixed + misc split), service templates
• File routing: CIds with 01-12 prefix → month files, else misc/{first-digit}.json

Core Scripts

• convert-services.ts — Service XML to JSON conversion
• enrich-lives.ts — Fuzzy matching and enrichment pipeline (Chetyi-Minei + Bulgakov)
• validate-data.ts — Main validator
• convert-bulgakov.ts — Bulgakov's Desktop Book EPUB to JSON conversion

Recent Work Context

Completed Enrichment

• Chetyi-Minei import: 1154 chapters processed, 1190 lives enriched
• Bulgakov import: 332 entries from "Настольная книга" Menaion section, 13 new lives enriched
• Manual fixes: 224 manual corrections in enrich-lives.ts (64 Minei + 9 Bulgakov + others)
• Bundle fixes: 868 Иаков Боровицкий corrected from 05-22 to 10-23
• Coverage: 1203/3046 lives have texts (sources: Chetyi-Minei + Bulgakov)

Validation Status

• All data files validated
• TypeScript compiles cleanly
• Build succeeds without errors

Critical Invariants

• Never overwrite existing life.text — enrichment only fills empty entries
• Bulgakov is secondary source — fills gaps, never overrides Minei
• File routing is strict: CId prefix determines file location
• Bundle CIds must exist: Menaion CIds require corresponding lives entries
• Static data is tracked: static/data/ in git (except scripts/output/minei.json)
• Validation must pass: Changes must pass tsc --noEmit, npm run build

Key Script Quick Reference

# Development
npm run dev              # Start dev server
npm run build            # Production build

# Validation
npx tsc --noEmit                 # Type checking
npm run build                     # Build verification
npx tsx scripts/validate-data.ts  # Main validator

# Enrichment (Minei)
npx tsx scripts/enrich-lives.ts              # Dry run
npx tsx scripts/enrich-lives.ts --write       # Apply

# Enrichment (Bulgakov)
npx tsx scripts/enrich-lives.ts --bulgakov    # Dry run
npx tsx scripts/enrich-lives.ts --bulgakov --write

Important Notes

Pipeline Dependencies

• Chetyi-Minei source: EPUB conversion requires convert-minei.ts
• Bulgakov source: EPUB conversion requires convert-bulgakov.ts
• Enrichment workflow: Requires minei.json + bulgakov.json + menaion-bundle.json
• Validation chain: Each commit must pass typecheck → build

File System Constraints

• scripts/output/minei.json is gitignored (33MB source file)
• scripts/output/bulgakov.json is gitignored
• static/data/ is fully tracked in git
• Lives files: month files (01.json-12.json) + misc split (misc/0.json-misc/9.json)

Current State

• Total CIds: 3046
• Lives with text: 1203 (Chetyi-Minei + Bulgakov)
• Unmatched Minei: 27 (floor: narratives, no-target, already-filled)
• Unmatched Bulgakov: 121 (all no recoverable targets)
• Latest enrichment commits: e32d787 (Bulgakov), c342a5b (orthography), 08950cd (64 fixes)
