 ## Current state
 - **Phase:** ALL PLAN tasks complete (P0–P7). GLB + OBJ/FBX/DAE/IFC loaders (SSR+CSR) + on-screen FPS + adaptive quality (<60fps→pixelRatio degrade). Build verified (tsc 0, vite exit 0).
- **Last action:** Phase 6+7 via dynamic workflow `multiformat-viewer` (7 agents) — multi-format dispatch (src/viewer/modelLoader.ts), web-ifc single-thread IFC, FPS overlay + adaptive ladder. Samples+previews per format.
+- **Last action:** Gitea #7 runtime artifact 경량화 — Three.js hashed decoder 통합, single-thread IFC staging, production artifact budget와 Draco/Basis/IFC subpath E2E 검증.
 - **Blockers:** none. KTX2 *production* encoding still needs KTX-Software/toktx (runtime decode verified). web-ifc multi-thread는 COOP/COEP가 필요해 배포에서 제외하고 single-thread를 사용합니다.
- **Next:** optional in-browser per-format smoke (/verify-viewer .ifc/.fbx); OBJ/DAE geometry-only on blob: URL (accepted); document.hidden FPS guard.
+- **Next:** OBJ/DAE geometry-only on blob: URL (accepted); document.hidden FPS guard.

 ## Work log
- 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.
