37 headless tests covering the logic that is cheap to break: - split planner: plan_disc_split, chapter helpers (whole-fit, multi-disc partition, single-movie chapter/even-cut split, contiguous coverage) - High-profile fill-disc bitrate math (disc count + bounds + capacity) - ffmpeg command generation: profiles, text/image hardsub, 2-pass, nice, progress-to-file, even pad/crop + positive offsets, -ss seek, and the AC3 448k audio-clamp regression - ffprobe subtitle detection: text/image classification, tags/disposition tests/conftest.py makes the in-tree package importable and installs the gettext _ builtin so modules run headless. Forgejo Actions workflow runs the suite on push/PR. Update CLAUDE.md's testing section accordingly. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
