- render: CSM cascades and spot/point shadow faces draw inside a per-draw scissor, with a depth shader that has no discard for solid and rigid casters (downtown city shadow pass 3.3 ms → 0.4 ms, spot shadows 2.7 → 0.1 ms); cascade selection by caster bounds on Apple; per-frame model draw order built once; clustered light terms per pixel; foliage wind, impostors, grass and LOD model sets; city glass and interior light; the viewmodel eye-space fix for narrow panes; joint-following parts use the skin's exact joint matrix. - model / csg / mesh_edit / remesh / gltf: makepad_csg_math::portable (sin/cos/atan/exp/ln/pow/hypot/cbrt from exactly rounded operations), used at 320 call sites, so a model hashes and builds byte-identically on macOS and Linux (MODEL_GENERATOR_VERSION 2, CHARACTER_GENERATOR_VERSION 42; tests/portable_identity.rs); lathes always face outward; sculpted-shell booleans with a tolerant surface map; decal and badge lettering; LOD model sets; grip poses for first-person arms. - platform: DrawCall scissor rectangles (Metal and Vulkan; other backends keep the old clip); draw_shader_ready for a fallback while a pipeline compiles; Metal clock reads once per frame; Linux render-texture readback. - audio_synth: score.rs and its Sequencer are removed; game music now runs on Stage's Score engine; drum_note moves into instruments.rs. Includes Stage SF1's SoundFontInstrument change: programs share one loaded font instead of ~300 MB each. - ai: the sfx model generates at whole seconds and trims to the requested length (fractional lengths came back as noise); fleet roles let node 165 serve audio as a fallback. - widgets/core: screen recordings of any app inside a Makepad checkout land in <makepad>/local/screencap. - fab: FabDragNumber read_only, for the sandbox time dial. Checked on node 165: cargo check --release --workspace; makepad crate suites 1442 passed; sandbox 3095 passed; portable model hashes identical on the Mac mini.

//! One program, one product, on every machine. Models built on a Mac and on

//! Linux must be byte-identical: the store addresses built products by
|
|
//! content, so a product that differs per platform splits the store and
|
|
//! misses every cache the other machine filled. These goldens were recorded
|
|
//! on Linux (node 165) and pass unchanged on macOS (the Mac mini); a
|
|
//! transcendental routed back through the platform libm breaks them there.
