- Add hardening tests to kill mutation survivors across client, DB, and indexer (hex guards, poll byte-limit boundaries, busy-flag defaults, parseTxid empty-string, polls controller handleError, memo-codes isMemoPrefix, normalizePollCreateDatas, storePollChildRecord returns). - Reduce duplication: extract shared reflect/isTooLong into MemoTxidAction (client), shared _run into the polls controller and configurable execute into PollReadUseCase (DB). - Refresh mutation manifests and Gherkin acceptance-mutation stamps. By architect.

Unit tests for the hex helpers used by Memo poll actions.
|
|
|
|
Memo actions that embed a parent poll txid use hexToBytes to decode the
|
|
64-character hex txid into 32 raw bytes. These direct tests pin the length
|
|
and hex-validity guards independently of the memo-poll broadcast path that
|
|
also reaches hexToBytes through buildTxidTextPayload.
