# whisrs check-issue55 — scripted sanity check for issue #55.
#
# Generates the synthetic dictation fixtures (if missing) and streams them
# through LocalWhisperBackend the same way the daemon does:
#
#   1. issue55.wav          pause-heavy dictation — must transcribe with no
#                           repeated n-grams (the original issue #55 repro)
#                           and >= 80% ground-truth word coverage, so silently
#                           dropped words fail too.
#   2. issue55_nopause.wav  ~28 s of continuous pause-free speech — must be
#                           transcribed in full (>= 80% ground-truth word
#                           coverage), proving the 20 s max-segment cap emits
#                           instead of stalling.
#
# Exit code: 0 = both checks pass, 1 = at least one failed.
#
# Usage:
