RNS 1.4.2 Transport.receipts_check_interval: the reference only fails receipts on a once-per-second culling pass, so a proof landing past the nominal deadline still validates until the next pass. On a fast link its effective deadline is rtt × 6 plus up to a full second. We enforce deadlines precisely, so the interval rides on the deadline itself: a receipt fails exactly when the reference’s last-possible pass would have failed it.
A sealed link data packet framed under the given wire context: WireContext::None for plain link data, or a resource-family context (an advertisement, a part request, a hashmap update).
A link packet whose payload rides exactly as given. No token around it.
What RNS 1.4.2 Packet.pack does for context RESOURCE (parts are slices of an already-sealed stream) and RESOURCE_PRF (the proof is a bare hash pair on a PROOF-type packet).
