Overall Score 20%

Overview Phases Roadmap

0 = Missing

1 = Planned

2 = Partial

3 = Production

4 = Hardened

5 = Institutional

100%

Core vault reader, metadata extractor, and context builder. Solves AI memory limitation with minimal footprint. No API surface, no database, no UI.

5 capabilities Target: 100%

Improved ranking, tag/title/heading boosting, cached note catalog, note summaries, better truncation and deduplication.

4 capabilities Target: 100%

Admin-only API endpoints for search, context generation, and vault health. Internal route wiring with fail-closed auth.

3 capabilities Target: 100%

Readiness scoring, metadata coverage, stale note detection, broken link checks, architecture domain coverage gaps.

3 capabilities Target: 100%

Embeddings/vector search, database-backed index, advanced ranking, cross-platform AI knowledge service. Only if real usage proves need.
