52 packs, 4442 GLB models, 136 MB on disk — fetched sequentially with resume
(a hash-valid pack is skipped, so an interrupted run costs nothing) via
kenney.nl's content-hashed URLs with per-zip sha256. MIRROR.toml records
every pack's canonical URL, sha256, size and file count, so a mirror is
reproducible; --mirror=/ARCADE_ASSET_MIRROR redirects the base URL and fetch()
verifies the digest identically whatever host served the bytes — a mirror we
control is never trusted more than upstream. --packs= keeps a fresh clone from
being forced to pull everything.
Aliases restructured to survive the scale: per-pack theme rows (55) so every
model in a pack inherits its setting, filename-token parsing with variant-
marker stripping as the workhorse, and ~240 hand-curated query-time synonyms —
the layer whose curation compounds across the whole catalogue. 82-query suite
reports misses instead of being tuned green; the list is down to 2, both
defensible (a floor IS somewhere to stand; a bell IS a metal clang).
Three ranking bugs root-caused, not patched:
- No stemming, so "smashing" never reached the alias "smash" and "glass
smashing" returned glass PIPES. Added a conservative stemmer probed at
synonym strength (only ever adds matches), which refuses to mangle
glass/grass/class and routes "trees" to "tree", not "tre"
- An overreaching alias: `spaceship` sat on four spaceEngine SOUND families.
An engine hum is not a spaceship. Removed; "spaceship engine" still resolves
- Kind confusion on ties: spacecraft models tied with spaceTrash sounds and
lost the alphabetical tie-break. Added kind-aware tie-breaking driven by
query intent — deliberately a TIE-BREAK, not a score bonus, so it cannot
drag a weak model above a strong sound (laser gun / explosion / coins scores
verified unchanged)
Repo-policy violation fixed: all three asset .gitignore files were deny-lists
covering only .glb/.png/.jpg, leaving 302 .gltf files from 3d-road-tiles fully
committable. Converted to allow-lists — 4,744 asset files are now unstageable
by accident.
Scale at 4,999 entries: build 120 ms, search ~0.2 ms, 2.1 MB heap, and the
prompt summary still 479 chars — flat as the catalogue grows, which is what
keeps it affordable in every AI turn.

- libs/game/render/skin.rs: GLB container + owned-JSON parser, dense
accessors, multi-primitive skinned meshes, skin + inverse binds, full
node-hierarchy palette, T/R/S clips (linear/step), nlerp blending.
Hermetic tests via an in-code 2-joint GLB; real-asset test skips with a
hint when the download hasn't run
- DrawGameSkinned shader (PbrVertex + albedo texture, terrain-style
lighting); skinned batch draws between opaque and alpha passes.
CPU skinning for now (sub-ms at 3716 verts): the uniform_buffer GPU path
has zero in-tree runtime consumers — SkinnedModel::palette is the seam
for the GPU swap
- apps/arcade: download_assets.sh (KayKit pinned commit + sha256,
idempotent, dir gitignored, CC0 license note in-repo); Knight patrols
the demo world with idle/walk blending, yaw follows path; captures
verified (pose advances, depth-occludes correctly)
- renderer binary_search sites use the shared sorted-id helper from M0r
