# SIM_SPEC §7.6 cross-architecture parity reference scenario.
# The simulator's events.ndjson hash for this scenario is checked in
# next to the test (`tests/cross_arch_parity.rs`). A mismatch is either
# a deliberate spec amendment with justification, or a determinism bug.
#
# RELAY_SPEC extension: the alpha↔charlie pair is routed through the
# `R` relay so the parity test also gates the relay vertex's
# determinism. Direct edges still cover alpha↔bravo and bravo↔charlie.
