Squashed from work:
- docs: button shader annotations — widgets/button.rs complete + splash demo buttons
- tweaker: the Shader tab shows the pinned widget's ANIMATOR STATES as little posed swatches under the well — one per tr
- widgets: the glass stops reading draw_pass.time, so glass apps idle again
- render, sim, platform: what a strategy round needs underneath
- draw, platform: overlays now composite above content that uses draw_depth
- asset: mp4 sample index for range-streaming, chat tools, import profiles
- platform: native file and save dialogs, in-house on all three desktops
- sim: a per-unit decision hook — one commandable unit can think for itself, before the kit steers
- makepad_ai is deleted — every backend is a hub pipe, the agent seam lives with its consumers (aicore §14, decided 2026
- libs: the zero-warning sweep — stitch casts say what they mean, xatlas keeps upstream's surface quietly
- zero-warning sweep, round two — the first full-workspace pass
- zero-warning sweep, round three — the model lanes and the deep examples
- zero-warning sweep, round four — the last stragglers
libs/render picks up the two biggest new modules in the group: `level.rs`
(the imported-world runtime) and `player_nav.rs` (walkable-surface planning
with clearance bands). The renderer, shader set, GPU lightmap and skinning
paths all grow with them — a chart-edge texel is no longer trusted with a
skirt's light, a lamp only receives what the sky is not already delivering,
and lamp photometry comes from the fixture rather than the mesh scale. A
`walk_probe` example drives the navigation directly.
xr gets splat packing and a GPU splat sort (`splat_pack.rs`, `splat_sort.rs`,
with tests), and view_splat is largely rewritten on top of them.
remesh, xatlas, gltf, splat and sim carry the supporting work: the xatlas
unwrap hang is fixed and the pass is several times faster, the glTF writer
emits the rig and vehicle contracts, and sim grows the entity layer the
imported worlds drive.
