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)

feat(assets): binary asset store + artifact entity + wiki evidence (Issue F)
Wires visual evidence into the knowledge graph. Images, PDFs, and CAD
exports can now be uploaded, deduped by SHA-256, thumbnailed, linked to
entities via EVIDENCED_BY, and rendered inline on wiki pages. Unblocks
AKC uploading voice-session screenshots alongside extracted entities.
- assets/ module: store_asset (hash dedup + MIME allowlist + 20 MB cap),
get_asset_binary, get_thumbnail (Pillow, on-disk cache under
.thumbnails/<size>/), list_orphan_assets, invalidate_asset
- models/database.py: new `assets` table + indexes
- engineering/service.py: `artifact` added to ENTITY_TYPES
- api/routes.py: POST /assets (multipart), GET /assets/{id},
/assets/{id}/thumbnail, /assets/{id}/meta, /admin/assets/orphans,
DELETE /assets/{id} (409 if still referenced),
GET /entities/{id}/evidence (EVIDENCED_BY artifacts with asset meta)
- main.py: all new paths aliased under /v1
- engineering/wiki.py: entity pages render EVIDENCED_BY → artifact as a
"Visual evidence" thumbnail strip; artifact pages render the full
image + caption + capture_context
- deploy/dalidou/docker-compose.yml: bind-mount ${ATOCORE_ASSETS_DIR}
- config.py: assets_dir + assets_max_upload_bytes settings
- requirements.txt + pyproject.toml: python-multipart, Pillow>=10.0.0
- tests/test_assets.py: 16 tests (dedup, cap, thumbnail cache, orphan
detection, invalidate gating, API upload/fetch, evidence, v1 aliases,
wiki rendering)
- DEV-LEDGER.md: session log + cleanup note + test_count 478 -> 494
