feat: Phase 1 ingestion hardening + Phase 5 Trusted Project State
...
Phase 1 - Ingestion hardening:
- Encoding fallback (UTF-8/UTF-8-sig/Latin-1/CP1252)
- Delete detection: purge DB/vector entries for removed files
- Ingestion stats endpoint (GET /stats)
Phase 5 - Trusted Project State:
- project_state table with categories (status, decision, requirement, contact, milestone, fact, config)
- CRUD API: POST/GET/DELETE /project/state
- Upsert semantics, invalidation (supersede) support
- Context builder integrates project state at highest trust precedence
- Project state gets 20% budget allocation, appears first in context
- Trust precedence: Project State > Retrieved Chunks (per Master Plan)
33/33 tests passing. Validated end-to-end with GigaBIT M1 project data.

feat: implement AtoCore Phase 0 + Phase 0.5 (foundation + PoC)
...
Complete implementation of the personal context engine foundation:
- FastAPI server with 5 endpoints (ingest, query, context/build, health, debug)
- SQLite database with 5 tables (documents, chunks, memories, projects, interactions)
- Heading-aware markdown chunker (800 char max, recursive splitting)
- Multilingual embeddings via sentence-transformers (EN/FR)
- ChromaDB vector store with cosine similarity retrieval
- Context builder with project boosting, dedup, and budget enforcement
- CLI scripts for batch ingestion and test prompt evaluation
- 19 unit tests passing, 79% coverage
- Validated on 482 real project files (8383 chunks, 0 errors)
