 # AR → OGAR → SurrealQL — OP-Arm Canonical-Contract Plan
 
-> **Status**: NEGOTIATED. Doctrine [lance-graph#546] is merged (OGAR IS the
->   AR-shaped THINK/DO compiler — curators feed it, it does not adapt to them).
->   #546 landed **doctrine only — no code**. This plan is the *contract layer*
->   downstream of it: it turns the OpenProject curator-arm feedback into concrete
->   OGAR Core contract requirements. OGAR Core has accepted the split —
->   **items 1–5 are flip blockers (Phase A), items 6–12 are promotion candidates

-> **Subordinate to**: #546 defines the doctrine; this defines the stable OGAR Core
->   contracts the OpenProject arm needs. Not to be smuggled into lance-graph
->   Inc 1 / Inc 2 — it is its own plan.

 3. `OntologyRegistry::register_actions(class_id, &[ActionDef]) -> Result<(), RegistryError>`.
