Keep every saved segment, show the longest clip with an expand list, branch on extend, and parse shot 2/3 blocks into a shared-duration queue with live part status.
The overall bar made a long queue look stuck at ~9% during the first clip, and nothing was written until the last step. Save checkpoints, use per-step progress, and stop treating a short Comfy history lag as a dropped job.
Purging desktop files let MiniMax reuse MiniMax_H3_00001_, so the next job returned the previous clip. Ignore stale events from the last job so a second generate cannot paste the first video over the new one.
The slider never left this machine, so deploy the generate UI with separate input/output hide toggles, reconnect in-progress jobs after refresh, and delete Comfy input/output files after they are saved to the library.
