Model Ingestion

Implemented

Presign → R2 PUT → complete_upload → RQ ingest_structural_file. Re-ingest DETACH DELETEs the prior graph for that file.

Framework01 03

State machine

Upload → created → uploaded → queued → ingested | error.

Element recognition is a second job type: element_recognition.

No graph snapshot of the previous ingest. History is Decision Memory snapshots, not ingest history.

IFC uses ifcopenshell per element; STEP mesh is display-only unless OCCT is on.
