A drag with a clip picked could span a new clip in the strip or span the picked one anew over the wave. Both happened by accident while working on a clip. Now a drag only makes a new clip while none is picked. With one picked it moves its edges or the whole of it. - With no clip picked, a drag in the strip or over the wave (in the Video tab the track) spans a new clip, as before. - A click over the wave or in the track picks the clip at that point, as a click on its band does. Beside the clips it picks the sound or the video. The picked clip wins where clips lie over each other. - With a clip picked, its handles move its edges as before. A drag on its band in the strip moves the whole clip, its length kept and inside the file. Any other drag does nothing. - The rules live in waveView.ts (clipGrip, clipToPick, movedSpan) and both tabs use them. The cursor shows grab over the picked band. - The Video tab's track draws the clips not picked faint, as the wave does, so a click there has something to aim at. Tests: - Unit wave-view.test.ts: 16 tests (4 new) - Counter-check: a strip drag beside the picked clip spanning a new one again fails the picked-clip rule test - e2e 34 + 66 (atx): ALL PASSED, 162 checks, 1 new check in each - Gate (atx): 295 files, 4527 tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
