Amount (TKAS)Reply deadline — silence refunds you

Enforced on-chain: only the recipient can claim, and only with a transaction that carries a reply. After the deadline, the refund needs nobody's permission and can only pay you back — a reply, or your money back; late replies lose to the refund. No protocol fees, ever. Message text is encrypted; addresses, amount and deadline are public on-chain.
