Build the viewer's layers from+FUSION SOURCE TRUTH instead. The merged GLB is why components can't be identified and why+the inner copper is faked from gerber raster PNGs.++## Decisions already locked (do NOT re-ask)++- Machine-pins layer = ALL 14 (MP1..MP14), by NAME from Fusion. Anchored, never animated.+- Everything else (C*/R*/U*/L*/J*/D*/Q*...) -> "Components" layer (the animated top layer).+- Inner copper L2/L15 must be REAL VECTORS from Fusion, same PBR copper material as outer,+  NOT gerber PNG planes.+- Fusion is NOT open on the board -> must open by URN first (Main project, doc v222).++## PROGRESS 2026-07-16 (started, then hit context limit + relay flap)++- ADOMGPU: Fusion NOT installed (fusion_readiness). Use AdomLapper instead.+- AdomLapper: Fusion INSTALLED. `fusion_start` SUCCEEDED (addinReady:true). Active doc = "Untitled"+  (board NOT open yet).+- BLOCKER hit: locating the board in the cloud. `fusion_search_cloud_files {query:"BQ25792"}` and+  {query:"BQ",project:"Main"} both returned 0 files (searched only 1 folder — search scope/project+  arg may be wrong). `fusion_walk_cloud_tree` then returned a stale "call fusion_start" hint = relay+  FLAP (Fusion was running). Retry the walk/search after re-confirming fusion_get_app_state; may+  need the exact project name or a cached URN. The .f3d is ALSO already on the wiki page+  (bq25792-charger.f3d in /tmp/bq25792-charger) — could fusion_aps_upload + open that, or open the+  local f3d directly, instead of hunting the cloud original.++## Exact plan (one source pass fixes BOTH components + copper)++1. On AdomLapper: Fusion already startable. Open BQ25792 — either find the cloud URN (retry+   search/walk after app_state re-confirm) OR just open the local .f3d from the wiki page+   (/tmp/bq25792-charger/bq25792-charger.f3d) which is the same v222 design.+2. `fusion_run_modeling_script` — ONE script that:+   a. Walks the occurrence tree; export each occurrence's mesh tagged by designator.+      MP1..MP14 -> machine-pins group; all others -> components group.+   b. Pulls each copper layer's polygons (top/L2/L15/bottom) as geometry.+      Two options: (i) the Electronics board API trace/polygon geometry, or+      (ii) `fusion_export_dxf` per copper layer (DXF = vectors) then triangulate closed polys.+      NOTE the earlier gerber2glb bug: gerber coords are MILLI-UNITS; I mis-scaled (÷1e6 vs+      the real viewBox units) which blew the mesh up to a speck. DXF avoids that; if reusing+      gerber2glb (/tmp/gerber2glb.mjs), fix the unit scale against the viewBox first.+3. Rebuild the viewer layers from that source data. The engine already works — only the layer+   SOURCES change. Keep: cascade-up animation, layers panel (live z + visibility + hover-+   highlight), realtime order check, Play/Pause + scrub (2-min resume), draggable floaties,+   Click-pivot toggle (camera.setClickToSetRotationPoint), Ground toggle, deterministic+   framing (radius 0.115 at board center 25.2,13.2,18mm — computed diag blows up, don't use it).+4. Verify on AdomLapper (session bqview, hwnd in /tmp/bqview_hwnd.txt), flash, show John.++## What already works at v0.1.49 (don't regress)++Native Adom Babylon9 viewer + ViewCube; cascading UPWARD explode (nothing below ground);+layers panel; order check; Play/Pause + scrub; Click-pivot + Ground toggles; Fullscreen;+draggable floaties; unified PBR copper (albedo 0.95,0.60,0.42 / metallic 1 / roughness 0.28 /+envIntensity 1.2); transparent ground (alpha 0.2) + every-frame shadow refresh.++## Key infra facts++- readme CSP: connect-src 'none' -> models ride as lossless PNGs in the repo (bytes in RGB,+  4-byte LE length header), decoded via CORS canvas (loadPngBytes). ~4-5MB readme cap.+- Storage shim in <head> (sandboxed docs throw on localStorage -> aborts the bundle's rig).+- Blob->dataURI shim in the module (img-src has no blob:).+- Group GLBs: optimize with --instance false; do NOT quantize (bounds lie); images -> data URIs.+- Publish loop: repo push + `adom-wiki pkg publish --org adom --public -y`, bump version in+  BOTH package.json and page.json.+- Platform asks on adom/wiki #47 (CSP, size cap, /blob content-types, iframe height,+  allowfullscreen, deployed-bundle sandbox rig, native exploded-animation mode).++## Skill draft (private, NOT yet shipped — too hacky per John)++/home/adom/project/wiki-readme-3d-skill/SKILL.md — full recipe.
