# Context Engineering
**Multi-corpus context engineering — indexes your codebase ([lat.md](https://github.com/1st1/lat.md)-compatible), Granola transcripts, Notion DBs, Gmail labels, HubSpot notes. Depth-aware packing. Concept-quality scoring.**
The engine for building and querying a token-efficient, provenance-tracked company brain across code, human-curated knowledge, and connector streams.
Five tightly-coupled capabilities ship as one skill:
1. **Multi-source indexer** — AST (14 languages via tree-sitter) + markdown heading trees, schema-versioned cache, incremental re-indexing.
2. **Source ABC** — the contract connectors implement to feed events into the brain. This skill ships `WorkspaceSource` + `GithubRepoSource` only; Notion / HubSpot / Gmail / Granola adapters live elsewhere (Anabasis spec calls this `SignalSource`).
3. **EntityStore** — three-tier brain layer: `raw/` (verbatim sources) + `events/` (append-only JSONL of extracted claims) + `wiki/<slug>.md` (consolidated entity pages with full provenance — every cited claim resolves to file:line + content_hash + ts). Reference impl of Anabasis spec `EntityStore` ABC.
4. **Synthesizer + Auditor** — GAM-grade semantic-shift detector (consolidate only on cosine drift, never on every event); `wiki_init.py` one-shot seeder; Auditor proposes splits / merges / contradictions / dead links.
5. **Retrieval surface** — depth-aware packer (2 levels — full / pointer, 95% budget utilization) + multi-hop reasoning paths through
