game_view.rs 4525 -> 1878. Deleted in one marker-verified cut: the 84-arm
game_dispatch chain, all arg/option/value helpers, spawn_entity/spawn_terrain
/spawn_car/spawn_plane/spawn_character/spawn_block_body/set_brain, the
GAME_API table, suggest_verb/edit_distance, and the duplicated CallbackTable.
register_game_handle now binds game_script's verb table; unknown verbs keep
the same hard-fail plus did-you-mean. Kept: run_tick and everything parity
depends on — tape input, gamepad poll, camera mailbox, perf channels, agent
RPC, save/log flush.
Rollback deliberately still gamemaker's hand-written WorldSnapshot, not
GameWorld::clone(). Clone is strictly safer and is what Arcade uses, but
eval_body is the parity-critical path and the snapshot is what the tape was
established against — swapping it deserves its own tape run, not a rider on
a 2700-line deletion.
Three pre-existing divergences fixed in game_script (sfx/beep/jingle predated
the 31-verb port and had drifted): beep's `to` defaulted to 0.0 instead of
freq, so every beep swept to silence; beep never read its wave option at all
(allowed but unused, and AudioRequest::Beep had no wave field); gain and
jingle ms were off. Audio drains host-side in run_tick and after a successful
eval so a startup jingle isn't held a frame; a failed eval discards its queue.
Regression the migration exposed: block verbs spawn through the shared box
path, which re-validated keys against the BOX allow-list, so game.car(...)
logged 8 bogus "unknown option" warnings per eval straight into the channel
the agent reads. Added spawn_entity_unchecked for the block path; a real typo
on game.box still warns. Racing fixture: 8 warnings -> 0.
Tape probe BYTE_IDENTICAL (re-run after the audio and warn changes too).

The thesis proof: examples/gamemaker/resources/fixtures/racing.splash is a
complete playable racing game in 72 lines (12-corner oval from a waypoint
loop, 4 cars, gates, standings, restart) with no physics, no AI and no lap
bookkeeping in script. Blocks run engine-side at 60Hz: Blocks::pre_step
(intent -> motion) before step_world, post_step after; Blocks is Clone and
snapshots beside GameWorld so a failed eval rolls both back together.
- game.car (4 suspension raycasts on a box3d rigid chassis), game.character
(drives the existing mover sweep + owns idle/walk/run blending),
game.plane; game.drive/autodrive/speed
- Brains: game.wander/chase/patrol/caught — the fixture's hand-rolled AI,
absorbed engine-side
- Race kit: spawnpoint, checkpoint, place, race, standings, lap/rank/
finished, score/score_of (Shared-tier data, ready for replication)
raycast_vehicle audit (defects documented in car.rs, still live in xr):
libm sin/cos in steering (unreplicable), a wrong side-impulse denominator
(iaj.dot(iaj) where it should be (I^-1 aJ).aJ), and an unguarded division.
Kept the structure, replaced Bullet's friction solver with an arcade force
model: suspension acts at the contact point, grip and drive through the
centre of mass, steering as yaw torque — no lateral force can generate
roll, so it is stable by construction rather than by roll_influence fudge.
Engine bug fixed at the source: GameWorld::new() left rng at 0 and
xorshift64* is a fixed point at zero, so rand() returned 0 forever for any
world built through the sim API. reset_content seeds on every eval, which
hid it from gamemaker entirely; found by a wander brain that never left home.
Tape probe byte-identical; racing fixture evals clean and drives (AI follow
the line, gates bank in order).

- 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

New makepad-converse crate: SpeechOutput/Playback moved out of gamemaker
(mix_into for custom audio callbacks, install_audio_output convenience);
TranscriptFilter trait + PassthroughFilter + FilterWorker thread (filters
built on the worker via factory since LlamaSession is not Send);
ConversePipeline wiring filter -> makepad_ai agent backend -> speech with a
ConverseAction stream, llm leg pluggable (claude-code / acp /
openai-compatible base_url for local servers). QwenFilter behind the
local-llm feature: chatml prompt, non-thinking prefill, greedy, SEND:/SKIP:
line protocol, fail-open parse; filter-repl bin for interactive testing.
Gamemaker's speech leg now uses the crate; its agent plumbing stays local.
