/*
12
-
* Why custom commit signing instead of jacquard's Commit::sign()?
13
-
*
14
-
* Jacquard previously had a bug in how it created unsigned bytes for signing:
15
-
* it set sig to empty bytes and serialized (6-field CBOR map), while the
16
-
* ATProto spec creates a struct *without* the sig field (5-field CBOR map).
17
-
* These produce different CBOR bytes, so signatures didn't verify with relays.
18
-
*
19
-
* The bug has been fixed in jacquard, but the fix is untested here.
20
-
* TODO: Switch back to jacquard's Commit::sign() and verify it works.
