Reply, topic message, add-poll-option, poll-vote, and create-poll now broadcast each protocol field as its own OP_RETURN script push instead of combining them into one push. The indexer requires three pushes for reply, topic message, and poll children, and accepts four for create-poll; the combined form was rejected or misparsed. hex.js builds the txid and text as separate pushes, and a new memo-multipush adapter teaches minimal-slp-wallet's single-push sendOpReturn to expand an array of fields into separate pushes. Acceptance step handlers assert the individual pushes, and unit/property tests cover the new shape. By coder.

Unit tests for the Memo reply wire encoding.
|
|
|
|
A reply action embeds the parent transaction txid as 32 raw bytes in
|
|
little-endian wire order: the reverse of the 64-character display txid. The
|
|
indexer reverses those bytes back into display order, so the client must
|
|
reverse before embedding.
