+## Group travel with an immediate payment — 29 October 2026
+
+**Prototyped / Partial.** A Basic classic group offer of three to six human
+participants can combine its one named travel term with one immediate bribe
+between two distinct participants. The proposer implicitly accepts the
+immutable offer, each other invitee accepts explicitly, and the named traveler
+accepts last. No payment is made on an earlier vote. The final acceptance
+settles the native bribe and binds the travel together; if payment or the
+current-turn travel completion fails, that acceptance and its payment roll
+back. The payer may be the proposer, traveler or another participant who has
+already accepted. The recipient collects their share under the native deferred
+bribe rule, and mutual release does not refund a settled payment.
+
+Native-action tests cover traveler and previously accepting payers, the absence
+of early payment, and rejected final acceptance with unchanged funds. Seventy
+focused cases pass across the related files. The actor-last consent order and
+structured term are provisional online compositions, not publisher limits on
+agreements. Deferred payments paired with travel, multiple payments, optional
+modules, broader combinations and deployed verification remain open.
