Parent: #3

Scope

ChainAdapter::prepare for TransferIntent::Transfer: Balances::transfer_keep_alive for ordinary accounts, ReversibleTransfers::schedule_transfer (with the chosen delay) when reversible is set or when the account is high-security and therefore may not send plainly. Fee via TransactionPaymentCallApi::query_call_info. The review summary is decoded from the encoded call bytes with the runtime metadata, not from the intent, and prepare fails if the two disagree. submit and status follow the extrinsic to InBlock and Finalized, surfacing a dispatch error's pallet and variant name.

Also: cancel_transfer for a pending reversible transfer, and listing PendingTransfersBySender.

Acceptance

Against Heisenberg: a reversible send appears in the pending list, is cancelled, and the balance returns; a plain send finalizes and the recipient sees it. A dispatch error (insufficient balance) reads as Balances::InsufficientBalance, not a hex code.

Depends on

Balances and nonce.
