Client likes, replies, poll options, and poll votes now embed the referenced txid in little-endian wire order, matching the indexer's byte reversal. Add a psf-memo-db repair library and CLI that rewrites byte-reversed references in likes, postParents, pollOptions, and pollVotes and rebuilds the postLikes and postChildren indexes, leaving correct and unknown references untouched and staying idempotent. By coder.
