+- 2026-07-29 — Gitea #7 runtime artifact 경량화: version 중복 5종은 incompatible/optional transitive dependency라 강제 override하지 않음. Three.js bundled hashed Draco/Basis asset으로 전환하고 `public/draco`, `public/basis`, `web-ifc-mt.wasm`, production source map 제거. artifact gate 추가. 3D dist 24,945,531→8,149,402 bytes(-67.3%), duplicate 0. Vitest 8, typecheck/build, Playwright E2E 17개 통과.
 - 2026-06-19 — KTX2 runtime path validated: toktx unavailable here (no native KTX-Software), so sourced the only single-file KTX2 GLB in Khronos — ABeautifulGame.glb (glTF-Binary-KTX-ETC1S-Draco, 11.5MB, 35 KHR_texture_basisu / 33 image/ktx2 / 17 Draco). perf-smoke load via viewer: **626ms PASS** (KTX2Loader + DRACOLoader decode confirmed). Corrected tools/preprocess.mjs doc: KTX2 CLI command is `gltf-transform etc1s|uastc` (needs KTX-Software 4.3+), not `ktx`. Samples now include KTX2+Draco variant.
 - 2026-06-18 — P4-3 prerender pipeline complete: added ThreeDViewer.rotateTo(azimuth) + `window.__viewer` exposure; wrote tools/prerender.mjs (puppeteer-core orbit capture → ffmpeg animated WebP). Fixed: MSYS path mangling of `/samples` argv; ffmpeg `libwebp_anim` broken in this build (1 frame) → switched to `-c:v libwebp -vsync vfr` (correct multi-frame). Produced public/previews/Duck.webp (24 frames, 54KB). Wired into main.ts: `?model=` sets `#preview` src to matching `/previews/<name>.webp` (onerror hides), hydration gate fades it on ready. P4-2 (3-size sample set) + P4-3 → done. Result/verify: `npm run build` exits 0; ANMF=24 confirmed.
 - 2026-06-18 — Asset pipeline validated + P5-3 perf smoke: fixed tools/preprocess.mjs (textureCompress ktx2 → webp; registered draco3d.encoder dependency + EXTTextureWebP). Ran on Duck.glb → 117.7KiB→31.2KiB (73.4% reduction, Draco+webp). Added `window` `hmw:ready` event in ThreeDViewer.onLoaded. Wrote tools/perf-smoke.mjs (puppeteer-core + system Chrome headless). Ran against preview: Box 102ms, Duck 94ms, Duck.optimized(Draco) 141ms, Avocado 271ms — all < 3000ms PASS. Draco runtime decoder path confirmed. P5-3 → done.

-# Basis Universal GPU Texture Compression
-
-Basis Universal is a "[supercompressed](http://gamma.cs.unc.edu/GST/gst.pdf)"
-GPU texture and texture video compression system that outputs a highly
-compressed intermediate file format (.basis) that can be quickly transcoded to
-a wide variety of GPU texture compression formats.
-
-[GitHub](https://github.com/BinomialLLC/basis_universal)
-
-## Transcoders
-
-Basis Universal texture data may be used in two different file formats:
-`.basis` and `.ktx2`, where `ktx2` is a standardized wrapper around basis texture data.
-
-For further documentation about the Basis compressor and transcoder, refer to
-the [Basis GitHub repository](https://github.com/BinomialLLC/basis_universal).
-
-The folder contains two files required for transcoding `.basis` or `.ktx2` textures:
-
-* `basis_transcoder.js` — JavaScript wrapper for the WebAssembly transcoder.
-* `basis_transcoder.wasm` — WebAssembly transcoder.
-
-Both are dependencies of `KTX2Loader`:
-
-```js
-const ktx2Loader = new KTX2Loader();
-ktx2Loader.detectSupport( renderer );
-ktx2Loader.load( 'diffuse.ktx2', function ( texture ) {
-
-	const material = new THREE.MeshStandardMaterial( { map: texture } );
-
-}, function () {
-
-	console.log( 'onProgress' );
-
-}, function ( e ) {
-
-	console.error( e );
-
-} );
