Move OpenCASCADE out of the merged editor image into occ_service: a separate
emscripten module (-sASYNCIFY=0, MODULARIZE, in-container -Oz finalize, 2N+8
pre-warmed pthread pool) booted lazily in a dedicated Web Worker on the first
STEP export or STEP/IGES model parse. kicad_editor.wasm ~190 MB -> 130 MB;
sessions that never touch OCC never fetch its 57 MB. STEP export works in the
browser for the first time: the unchanged desktop dialog runs EXPORTER_STEP,
whose wasm shadow suspends into globalThis.occService and the export bytes go
straight to a browser download (never entering the editor heap). STEP/IGES 3D
models parse in the worker via the oce shadow (S3D WriteCache/ReadCache wire).
- wasm/occ-service/: service CMake target (hooked from the kicad fork's
top-level CMakeLists, wasm/editor pattern), embind entry
(occExport/occLoadModel), wxConfig pre-js.
- wasm/stubs/{exporter_step,oce_plugin}_stub.cpp: EM_ASYNC_JS worker bridges
(callee-shadowing; no caller #ifdefs).
- web/standalone: provider installed whenever the kicad_editor bundle boots
(cross-face safe); ONE shared worker-boot source occ-worker.js (vite ?raw;
the e2e stub reads the same file) — blob worker with locateFile absolutized
against the glue URL; export download-name guard.
- deps: OCC builds with RapidJSON so its glTF/GLB writer exists — pinned to
the vcpkg master snapshot 2025-02-26 (24b5e7a8b27f), the same code official
KiCad consumes via vcpkg.json's opencascade[rapidjson]; rapidjson's latest
tag (v1.1.0, 2016) is ill-formed under modern clang.
- tests: occ-export dialog e2e (lazy-fetch boundary + STEP download bytes),
occ-probe incl. a 9-format matrix (step/stpz/brep/xao/ply/stl/glb/u3d/pdf),
3d-viewer-models hard-asserts the worker parse; occ provider stub installed
ambiently by the kicad fixtures.
Validated against desktop kicad-cli 10.0.4: geometric exact equality (bbox
delta 0 um, volume delta 0.0000%) for STEP/GLB/STL/BREP/STPZ across three
boards and option sweeps — with desktop OCC 7.9 vs wasm OCC 7.8; PLY/XAO/PDF
structurally equal; U3D same-size (quantizer float LSBs differ). Full kicad
e2e green on Firefox and Chromium; standalone verified end to end (lazy fetch
only on the Export click; export.step 60,628 B ISO-10303-21; loadModel 700 KB
STEP -> 569 KB scenegraph cache).

All four editors (PCB / Footprint / Schematic / Symbol) are now runtime --frame
choices of a single kicad_editor.wasm (178 MB at -O1 vs 147+82 separate; shared
wx/common/boost linked once). One editor per page load, as before; frames pcb /
fpedit / sch / symedit.
- wasm/editor/: the merged executable target (single_top + both kiface library sets,
whole-archive pcbcommon) + the safety-net focus-walk Kiface() dispatch TU. Gated by
KICAD_WASM_MERGED_EDITOR (kicad submodule bump carries the fork side: per-engine
Kiface/getter binding + ODR renames + dual-kiface launcher).
- wasm/bindings/: per-editor collab entries renamed pcbCollab*/schCollab* (JS names
unchanged); duplicate kicadOpenFile/kicadCollabOnSave + shared-name registrations
guarded behind KICAD_MERGED_EMBIND; new kicad_editor_embind.cpp registers each
shared JS name once, dispatching on the live frame.
- Build: kicad_editor app (build wrapper, target case arms, 3-object embind compile
with the ABI-critical flags, STUB_APP=pcbnew); docker/build.sh "all" =
kicad_editor calculator pl_editor gerbview (pcbnew/eeschema stay as explicit debug
apps); scripts/kicad/audit-merged-symbols.sh = repeatable ODR-collision audit (run
on kicad bumps).
- Frontend: Bundle type (bundle ≠ tool); TOOL_BUNDLE maps all four editors to
kicad_editor; explicit --frame tokens for pcbnew (pcb) and eeschema (sch); publish
list = the 4 real bundles.
- Tests/CI: five harnesses load kicad_editor.js with explicit frame tokens;
PCBNEW_FAMILY_SPECS renamed BIG_MODULE_SPECS + the 8 eeschema-family specs (they
now boot the merged module — SpiderMonkey x86 CI OOM routing); frame-runtime spec
covers all four frames from the one bundle.
Validated so far: frame-runtime 4/4 (each frame boots with the right title, no
aborts, no duplicate embind registration); 24-spec merged-module regression green;
3D raytracer renders. Known pre-existing failure: 3d-viewer title-bar drag deadlock,
fixed on main by 7630c7e (2N+8 pthread pre-warm) — picked up by the follow-up rebase.

The footprint and symbol editors are no longer separate WASM bundles: the frontend loads the parent pcbnew/eeschema bundle and passes --frame=fpedit / --frame=symedit (TOOL_BUNDLE + TOOL_FRAME -> Module.arguments in boot). Drops the two duplicate build+deploy targets and their wrapper scripts + vestigial embind; adds low-level harnesses (footprint_editor.html, symbol_editor.html) and a runtime-frame spec. Bumps the kicad submodule to the runtime --frame launcher.
The frame-runtime spec is listed in PCBNEW_FAMILY_SPECS so CI routes it to the chromium-ci (V8) project — its footprint case boots the pcbnew module, which OOMs SpiderMonkey on x86 CI. Includes the editor-unification dossier (research docs 01-04 + the as-built implementation record 05).
