Squashed from work; the fine-grained history is under tag archive/work-2026-08-26: - vjfx: 104 new presets — the transition lane fills out and the screen family goes wide - vjfx: three lanes land — engine hooks + hold stage, the videomesh engine, and the audio picture - vj: the thumbnail pipeline becomes one honest machine, and effects go livecodable - vj: thumbnails become mp4 — hardware-coded sheets at measured-4K cells, and the bake stops racing the GPU - store: the ceremony dies — batch publish, one transaction, and the engine stops re-reading its own log - store: the ceremony dies — batch publish, one transaction, and the engine stops re-reading its own log - vj: the console grows real transports, and the deck stops lying about reverse - vj: reverse earns a memory, and the effects stop aging - fab: a 3D creation shell and the viewer built on it

// TIME SLICE — the frame is sliced into scanline bands and each band runs
|
|
// on its own delay: the top of the picture is already on the new frame
|
|
// while the bottom is still holding the last one, and the boundary rakes
|
|
// down the frame once a beat.
|
|
//
|
|
// Pattern taught here: ONE STORED FRAME IS ENOUGH. A true per-line delay
|
|
// would want a whole ring of frames; the `hold` stage keeps exactly one and
|
|
// indexes the CHOICE by position — band n releases to live when the beat
|
|
// phase passes n/bands. The result reads as a per-line delay, costs one
|
|
// texture, and is bounded by construction (the phase is a 0..1 saw, the
|
|
// index a function of the band number — nothing accumulates).
