# wai.text.timed (extensions/timed-text.md): the reference module's unit tests (cue model,
# annotation, WebVTT, IMSC1 and its render-model bound, timelines, disclosure, and the
# 608 encoder and decoder) and tests/timed_text.rs (every file of the committed corpus,
# vectors.json and each expected .vtt, .ttml and .608.hex, regenerates byte for byte
# from its fixed seeds and no other file is there, wai-rs gives every case its stated
# outcome, the corpus covers every 608 code path, and §12 lists exactly the reference's
# codes); and, in the step of every independent verifier above, the corpus's second
# implementation, timed_text_verify.py, written from
# the extension's text and sharing no code with wai-rs, which verifies every event with
# live_events_verify.py, writes every output byte for byte from the text, parses each
# IMSC1 document with xml.etree, and requires every mutated copy of the corpus to fail;
# standard library only, run isolated (-I).
#
# The paths this step brings to the workflow's trigger, and why:
# wai/extensions/timed-text.md: tests/timed_text.rs requires this extension's §12 to list the
#   codes the reference reports, and the registry's wire identifiers test reads its sections.
