Plotloom Stitch and Deliver

When to Use

Use after all required episodes/epXXX/videos/clip-*/selected.mp4 files exist.

Inputs

• selected.mp4 clips under episodes/epXXX/videos/clip-*/
• Target episode id.
• Optional delivery request via nova-lark / lark-cli.

Outputs

• episodes/epXXX/videos/final.mp4
• Optional delivery note and Feishu/Lark delivery message or uploaded file.

Read These Resources When...

• Read references/ffmpeg.md before probing or stitching.
• Use templates/delivery-note.md after final verification or delivery.
• Use plotloom --repo <repo> media probe <path> and plotloom --repo <repo> stitch --episode <episode> for deterministic work.

Workflow

1. Find selected clips in episode clip order.
2. Stop if any required selected clip is missing.
3. Use plotloom media probe to inspect each input.
4. Use plotloom stitch to stitch selected clips; use --normalize only when the target media behavior is understood.
5. Save episodes/epXXX/videos/final.mp4.
6. Verify final file exists, is probeable, has nonzero duration, and matches expected clip count/order.
7. Deliver via nova-lark / lark-cli when requested.
8. Keep Feishu as delivery, not state center.

Final Verification Checklist

• final.mp4 exists.
• ffprobe returns success.
• duration is nonzero.
• source clip order is correct.
• no prompts/candidates/selection notes were mutated during stitch.

Stop Conditions

Stop after final probe and optional delivery. Do not mutate prompts, candidates, or selection notes.

Failure Modes

• Missing selected clip: report exact missing path.
• ffprobe failure: report incompatible/unreadable media.
• ffmpeg failure: report stderr/command failure clearly; do not hide errors.
• Delivery failure: final file remains canonical in repo; Feishu is not state center.
