#
#   1. assert the committed fixtures still match what the Python oracle emits
#   2. replay every recorded transaction through the Rust adapter, byte-for-byte
#
# Read-only with respect to the running backend: the oracle is imported as a
# library, no responder is started, no port is bound, no live service is
# touched. Safe to run while the Python backend is serving a live FIFA client.
#
# Use --regen to rewrite the fixtures after an intentional oracle change.
