Each stage can now fail independently, giving four upload paths: audio+overlay, audio-only, overlay-only, or speed-only video. Step 3a copies the video stream (no re-encode) when mixing audio, so step 3b failure still leaves a clean audio-mixed file to promote. Overlay failure notification now reports which quality was uploaded. https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
