## Deviation from Original Plan

**Original Plan** (ROADMAP_V018_PLANNING.md):
- v0.1.8: Q1 2026 - Research integration (PREMem, GENESIS, Spatiotemporal)
- v0.1.9: Q2 2026 - Advanced features

**Actual Execution**:
- v0.1.7: 2025-12-19 - Research integration complete (EARLY!)
- v0.1.8: 2025-12-27 - Quality improvements (AHEAD OF SCHEDULE)
- v0.1.9: 2025-12-29 - Multi-provider embeddings (AHEAD OF SCHEDULE)

**Reason for Acceleration**:
1. Research implementation was more efficient than estimated
2. GOAP parallel execution saved ~12 hours
3. Modular architecture enabled independent development
4. Clear success criteria prevented scope creep

**Impact**:
- 3-6 months ahead of original timeline
- All major research features available in production
- Strong foundation for v0.2.0 advanced features
