Mint a TYPED, signed attestation receipt for any tx/action — a structured per-transaction receipt schema distinct from flat notarization, wrapped around the live veritrack-attest spine (Ed25519 + SHA-256). Deterministic pure-function engine (receipt_kb.py): carries caller fields verbatim, rejects missing required fields, no lookahead/leaks/fabrication. Verify free.
