- libs/game/math: cross-arch bit-deterministic f32 kernel (f64-internal
fdlibm-style polynomial kernels, exactly-rounded IEEE ops only, zero
platform-libm transcendentals). Parity golden hashes recorded on aarch64;
equal hashes on every other target IS the determinism test
- libs/game/sim: the gamemaker world moved verbatim (entity/terrain/world/
queries/step — float expression order preserved so tapes replay
bit-identically). No Cx, no draw types, no ScriptObjectRef: script
callbacks are CallbackSlots resolved through a generation-tagged
host-side CallbackTable in game_view.rs; sim reset no longer touches audio
- examples/gamemaker: game_view.rs 5545 -> 4640 lines (script boundary,
rendering, input devices, host I/O remain); per-tick args/input objects
built via unchecked pushes + release_transient (flat-heap tick path)
- apps/arcade: Makepad Arcade app shell + workspace membership
- Verified: headless sandbox3d fixture (90 entities) boots end-to-end;
gamemaker/sim/math/script-test suites green
