Each pipeline now saves intermediate files permanently before the step most likely to fail, so a partial failure leaves a recoverable artifact: - daily_sunrise_video.sh: speed-adjusted video (*-sped.mp4) survives if the drawtext overlay step fails; deleted automatically on success - montage-mvt.sh: speed-adjusted video (*-Sped.mp4) survives if the music-mux + attribution overlay step fails; deleted on success - 4-seasons.sh / montage-mvt.sh / year-end-join.sh: explicit ffmpeg error handling with targeted notify.sh calls naming the failed step and the surviving artifact path - montage-mvt.sh / 4-seasons.sh / year-end-join.sh: clip-duration-sum vs music-duration drift check warns when cumulative float error exceeds 2 s https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
