Deterministic fixtures

  1. 01

    Canonical JSON uses deterministic, key-sorted serialization. Golden vectors pin the exact bytes covered by each signature.

  2. 02

    The reference capture agent also emits parity fixtures so native implementations must parse and re-serialize byte-identically.
