# The parity gates hash PCM bit-exactly against the CircuitPython oracle,
# and Linux (gcc) and Windows (MSVC) builds agree with it. On macOS arm64,
# clang's default -ffp-contract=on fuses multiply-adds into fmadd (baseline
# on AArch64, so contraction actually happens there, unlike x86-64 without
# -mfma), which perturbs last-ulp float results and broke verify_effects.
# Scoped to macOS the way the single-precision cell scoped its own flags
# (clean-build.yml): turn contraction off so every shipped wheel computes
# the same bits the oracle blessed.

# src/cp_compat/audiodsp_build.h for why it is computed and never stored, and why
# "unknown" is the honest answer outside a checkout rather than an error.
