Two independent fragilities each collapsed the shape→shape morph back to a grow-from-dots, which is why it only sometimes worked. The hold was 600ms against an arrival whose timing is DECODE time: the same track costs ~5ms once the session holds its waveform in memory but hundreds of ms to over a second on the first cold decode. 2000ms covers the cold case with room; fresh-stream searches take well past that, so the loading story still gets the lane. And the hold bailed on a bar-count mismatch — but the lane's width follows the song TITLE now, so switching between a long and a short name resizes the lane mid-gap and the guard threw the held shape away. Held and morphed heights are refitted to the new count instead (nearest neighbour — it is a moving start point, on screen for under a second). Four consecutive cached switches measured after the fix: minimum lane height 15.1 on every one (dots are ~2, the old dip hit ~5). Gapless playback is untouched — the hold and morph are pure painting, and the sink-append path never waits on the lane.
