Context crossmatch

A pre-ingestion compatibility gate for agent context: type any artifact (tool result, memory shard, peer output, document) by the content classes it carries, type the recipient agent in the same vocabulary, and get a crossmatch verdict before anything enters live context — TRANSFUSE, TRANSFUSE-REDUCED (automatic universal-donor, data-only form), or REFUSE — verified by sandboxed trial exposure under a signed, hash-bound antigen profile.

Nothing enters live context untested. Profiles are Ed25519-signed under a per-operator key (issued at registration, published for verification, rotatable — retired keys stay published verify-only so older profiles still verify). Fleet adds a recipient-policy registry and an audit log.

Solo $9/mo · Fleet $19/mo · Per-check API $0.005 per check (x402).
