NOT CROSS-COMPANY LOSS. Cross-company loss aggregation → LD Cross-company loss · Daily-driver portfolio steward → Mission Control. PF is the risk / ARIN plane — equity-portfolio diffusion across holdings.

IN Input · holdings

Math kernel · cognitive modules · governor · eternal audit. ARIN brain runs damped weighted graph diffusion on the ontology with bounded activation. Every gateway call carries an audit_id that joins the cross-phase evidence graph. Output is deterministic and bit-exact reproducible — no model in the loop, no Claude in the answer.
