The canon.

Every concept the platform names — 344 of them, across 22 types — in a living knowledge graph. Walls, promises, commitments, rings, doctrine docs, loops, load-bearing details. Each concept references others. Each reference is walkable. This is the substrate's self-knowledge, made queryable.

The canon lives at GET /v1/canon — no auth required. Sub-endpoints: /v1/canon/types, /v1/canon/by-type/{type}, /v1/canon/{urn}, /v1/canon/{urn}/neighbors.
