- Extract helpers in memo-like to bring all CRAP scores to 6 or below. - Consolidate duplicated rejection assertions in memo-like and like-tip-page tests. - Add hex unit tests to close a coverage gap. - Add property tests for hex round-trip, like validation, and spendable sum. By refactorer.

Unit tests for the hex conversion helper (src/services/hex.js).
|
|
|
|
Memo actions like replies and likes embed a post txid in the OP_RETURN
|
|
payload as raw bytes, so the helper must decode a canonical 64-character hex
|
|
string into exactly 32 bytes and reject anything else with a clear error.
