# Loudness (extensions/packaging.md §12): the reference module's unit tests (the integer
# logarithm exact at powers of two, BS.1770's calibration tone at -3.01 LKFS, silence and short
# programmes with no loudness, unsupported rates and layouts refused, a statement read back and
# its gain and receipt held) and the corpus's (it reaches every stated outcome, and a changed
# figure fails), and tests/loudness.rs (vectors.json regenerates byte for byte, wai-rs gives
# every case its stated outcome, and §12.7 lists exactly the reference's codes); and, in the
# step of every independent verifier above, the corpus's second implementation,
# loudness_verify.py, written from the extension's text and sharing no code with wai-rs, which
# writes each programme's samples from its formula, filters, gates and takes the integer
# logarithm itself, checks signatures with the shared _ed25519.py, reads §12.7, requires every
# mutated copy of the corpus to fail and drops each of its own checks in turn; standard library
# only, run isolated (-I). wai-pack's own tests (wai-pack.yml) run `wai-pack loudness`.
#
# The paths this step brings to the workflow's trigger, and why:
# wai/extensions/packaging.md: tests/loudness.rs requires §12.7 to list the reference's codes,
#   and loudness_verify.py reads it.
