## Progress Tracking
Created: 2025-06-24
Updated: 2025-06-25 (Multi-source phase completed)
Status: **PoC COMPLETE** ✅ | **Multi-Source COMPLETE** ✅

## Results Achieved ✅
- **1,630 total servers** from all sources (Official: 823, Punkpeye: 658, Appcypher: 149)
- **1,296 unique servers** after deduplication (334 duplicates removed)
- **3x server count increase** from original single source (823 → 1,296)
- **Multi-source tracking** with combined attribution: `"punkpeye-awesome (+official)"`
- **Smart deduplication** prefers detailed descriptions over generic ones
- **README integration** working with GitHub API for complete documentation
- **Incremental embedding computation** reduces build costs (only recompute changed servers)
- **Production-ready distribution** via GitHub Actions and precomputed data releases
- **Graceful fallback hierarchy**: Precomputed Data → Local Cache → Live Sources → Stale Cache

## Technical Architecture
- **Abstract ServerSource** base class for extensible multi-source support
- **Intelligent deduplication** merges servers from multiple sources
- **Precomputed data pipeline** with `scripts/build_data.py` and GitHub Actions
- **Robust error handling** with network failure graceful degradation
- **MCP protocol compatibility** (all logging to stderr, stdio transport)
- **Comprehensive test coverage** (29 tests passing across all modules)

## Production Readiness
- **Instant startup** when precomputed data available
- **Offline resilience** with stale cache fallback
- **Automated updates** every 3 hours via GitHub Actions
- **Cost-effective scaling** with incremental embedding computation
- **Clean release management** using data-latest prerelease tag
