Deleting a clip in Analyse now sticks. It used to come back on the analyst's next push; the deletion is now remembered and handed to every analyst's Angles as one of its own "deleted clips", so their timelines drop it too.
Clips deleted in Angles are removed here in the same way, whoever created them, including markers pressed in Piston. Last edit wins — a clip edited after it was deleted comes back for everyone — and a stale archive can never resurrect a deleted clip.
