# A grain-free wai.video.av1 base refined by wai.video.int_refine (extensions/platform-decode.md
# §6): tests/av1_refine.rs replays every case of platform-decode-conformance/grain-free-av1/
# through staged::StageSink from the committed reference frames, holds the probe and stage-0
# hashes to those frames, refuses the stream with only its grain flag set, and requires one
# changed sample to change that frame's stage hash. The libdav1d decode (feature av1_base)
# needs a system library no container image carries; the codec-wrappers job runs it. In the
# step of every independent verifier above, verify.py, the corpus's second implementation (its
# own AV1 reader, codec string and conversion, and staged_verify.py's sink), replays every case
# and requires every mutation to fail. Standard library only, run isolated (-I).
#
# The paths this step brings to the workflow's trigger, and why:
# wai/extensions/platform-decode.md: §6 is the text the corpus and both verifiers read.
