Grin as a new asset arm in the tips machinery (no grin-lws change, no custodial grin_transactions/grin_outputs port): - GrinClient::get_outputs([commit]) (funding: present+height=confirmed) + get_kernel(excess) (sweep spend-height); reached via state.chains.grin. - create-gating (supported_tip_asset grin, validate 66-hex commitment, confirmations_for_asset grin=10), grin_commitment column (migration). - confirmation worker grin arm: get_outputs present -> confs; amount AUTO-VERIFY with warn (voucher hides amount; not a theft vector; matches legacy). - sweep reconciler grin arm: get_outputs-absent + get_kernel height at depth 10 -> settle; absence-without-kernel -> no settle (recoverable, never missettle); reorg revert only on commitment reappearing; probe error never settles/reverts. - 5 grin tests + pure-helper unit tests; 251 lib + 24 tips green. Amount-verification note: the voucher's bulletproof rewind nonce is random + untransmitted, so it can't be rewound today; a clean non-custodial fast-follow is to have the client send the per-voucher rewind nonce and verify via rangeproof rewind (nonce reveals amount only, not spend authority).
