Reintroduce apps/arcade and the ten game crates that were ripped out of
the fork (assets, audio, blocks, coedit, gen, net, pkg, render, script,
session), from makepad-internal/dev. Reconcile against the fork's layout:
- makepad-game-sim/math come from the fork's existing libs/sim + sim/math;
the copied internal libs/game/{sim,math} are dropped and the kept game
crates plus arcade point at ../../sim and ../../sim/math.
- arcade AI is rewritten off the removed makepad-ai agent API onto the
makepad-ai-hub headless ChatProvider worker (example/cad pattern):
AiWorker{send,cancel,poll}, ai_worker_loop driving
ClaudeApiChatProvider(ClaudeCli), AiWorkerEvent availability/delta/
done/error mapped into the chat feed and authoring land_edit, with
main.rs send_message/cancel_request/event-drain rebuilt around it.
- the game-script sandbox is adapted to the fork's jailed splash storage:
every isolate gets mod.fs = splash_storage jail; splaes splash_storage
set_root_for_heap is now public so the ScriptHost (or Splash) can grant
a per-game jail root. ENT font: build.rs/dispatch.rs entities fill new
fork sim Entity/Part fields via ..Default::default(); world_raycast now
borrows mutably and returns the material id.
cargo check -p makepad-arcade and the game + arcade test suites pass.
Point the workspace at libs/asset and libs/render. Drop Arcade
frontend, gamemaker, rig, pack registry, physics, and the old
libs/game gameplay crates. Those live in the private sandbox repo.
THE BUG: GLB_MAGIC was 0x4655_4C67, which spells "gLUF" — not "glTF"
(0x4654_6C67). The magic check therefore rejected EVERY REAL GLB, probe()
returned defaults, and the entire 4,442-model library indexed with
rigged:false, animated:false, size:None. Size filters silently matched
nothing; no model was ever detected as rigged. Any claim made from that
metadata — including "Kenney has essentially no rigging" — was measuring a
no-op, not the catalogue.
It stayed invisible because THE TEST FIXTURE WROTE THE SAME WRONG MAGIC, so
the test and the bug agreed with each other. Fixing the constant broke that
test, which is exactly how a fixture should behave once it stops encoding the
defect. A second bug sat behind it: bounds() searched for "max" only AFTER
"min", but Kenney's exporter writes max first, so bounds would have failed
even with the magic fixed. Both fixed, both with regression tests.
Consequence: the previously-reported 120 ms index build was timing a no-op.
Real probing is ~1.8 s for 5,309 models, now cut to the declared JSON chunk
and parallelised across <=8 threads (std-only, order preserved,
deterministic). The proper fix is caching probes by path+mtime — NOT done, and
the perf bound is now 12 s with a comment saying why rather than a tight
number the test cannot control under contention.
KIT INVENTORY — 23 kits, 2,064 tiles, grouped so a query returns a coherent
visually-matching set instead of one tile from each of five kits. Tile size is
the MEDIAN horizontal extent (kits ship occasional double-width pieces, and a
mean lands between grid pitches — a value no tile uses). Highlights:
city-kit-roads 72 tiles @1.00, coaster-kit 183 @4.00, tower-defense-kit 160
@1.00, marble-kit 162 @1.20, platformer-kit 153 @1.00, modular-buildings 108
@1.00, racing-kit 112 @1.05. The most useful single fact: modular-dungeon,
-cave and -space kits have IDENTICAL role histograms — one layout algorithm
drives all three and the kit choice is pure theming.
Honest failure: city-kit-commercial (41) and city-kit-industrial (25) yield
ZERO roles — their files are building-a..building-z, whole buildings with no
role vocabulary. Grid-placeable but not composable; arguably not kits.
Adjacency ships as DATA (ROLE_ADJACENCY) for the composition layer and is
deliberately coarse: Kenney filenames say what a piece IS, never which edges
are open, so anything finer would be invented. Also added: role/kit/clips/
joints on entries, kits()/kit_tiles() grouping, a find_kit agent tool (<2 KB
so the AI can discover a coherent set before composing), and composition-intent
vocabulary.
Inert per the Kenney-only scope cut: clip extraction, Quaternius source
support, .gltf support — tested and harmless. 64 fetched Quaternius models
were deleted after verifying they parse (46 joints/13 clips).
