The Dockerfile installed ffmpeg but not libchromaprint-tools, so in any deploy the fingerprint and discover tiers were inert rather than broken: fpcalc_available() returned False, the command exited tidily, and a healthy-looking image silently never matched an ad. Cutting a real episode (rather than trusting detection metrics) showed a fingerprint match ends where the ad stops being recognisable, not where the break ends. One edge sat 2.3s inside the resumed narration and the cut ate the opening of "It was 405 on the morning of Thursday, June 19, 2014". Snapping to the nearest silence was tried first and measured worse, 2.3s to 2.88s clipped, because the closest silence was a pause inside the narration. Direction is the fix: starts only move later, ends only move earlier, so a span shrinks and never grows and every error leaves a sliver of ad rather than deleting a sentence. This only helps where silence exists. On that episode it tightened three of five edges and left the 2.31s clip untouched, since the ad-to-narration transition has no detectable pause. That residual is a detection-edge problem, likely BRIDGE_FRAMES extending a run, and is not solved here.

# adscrub: pipeline CLI + feed server in one image.

# Default command serves the cleaned feed(s) over HTTP; every pipeline stage is

# also available as a one-shot command, e.g.:
|
|
# docker compose run --rm adscrub ingest

# docker compose run --rm adscrub chapters

# docker compose run --rm adscrub transcribe

# docker compose run --rm adscrub cut

# build`) to pull in the cuBLAS/cuDNN extra for faster-whisper's CUDA path — only
|
|
# needed on a host that actually passes a GPU through (see CLAUDE.md).
