The runtime is JSPI-only; this removes everything that still pretended
otherwise. Three exhaustive sweeps (C++/JS+build+CI/tests+docs) drove
the inventory; every deletion verified by grep closure + full gates.
Broken-right-now fixes:
- deploy-staging.yml passed the retired opt_level input — the workflow
could not even start. Removed.
- env.sh carried dead exports with a live -sASYNCIFY=1 inside
(WASM_LDFLAGS/PTHREAD_LDFLAGS, zero consumers). Removed; the
WASM_LEGACY_EXCEPTIONS rationale rewritten to the real reason.
- docker/build.sh exported PCBJAM_ASYNC_BACKEND (read nowhere). Gone.
Dead weight removed:
- binaryen submodule (nothing builds or invokes it), wasm-opt-bench
workflow + scripts/bench/, get-wasm-opt.sh, diagnostics.js (242 lines
of Asyncify-API-only code), the KICAD_PIPELINE background-postprocess
scaffolding (existed to parallelize the deleted wasm-opt phase; the
postprocess is a seconds-long node script and now runs inline),
build-monitor's dead asyncify rows, sched-context orphan build
output, dead .gitignore entries, the .jspi-assets spike dir (the two
wf-result research JSONs moved to docs/features/async/migration-evidence/).
- bindings: fiber_park.h + its 12 embind registrations (broken-if-
called under JSPI), the kicadOpenFileStart/OPEN_JOB starter route,
main_stack_runner.h + 5 includes, the always-null context-sleep weak
hook in nanosleep_yield.c.
- shim: the backend field (installed-flag idempotency instead),
noteContextWait (dead both sides), the __wxAsyncifyDump alias (+ the
WasmTool fallback and string-dump normalize branch).
- web: the emscripten-6-ignored mainScriptUrlOrBlob option in boot.ts
(gerber-demo keeps it: it loads the deployed CDN release, which
predates emscripten 6 — noted inline).
Conditionals: all 'backend === jspi' checks reduced to scheduler-
presence checks; races_quiescent re-keyed from Asyncify.state (vacuous)
to real backlog quiescence (resumeReady/mutatorQueue — NOT _windowLive,
which is the probing activation's own window by definition).
Renames (identifiers only, no file renames): ASYNC_LINK_FLAGS→
JSPI_LINK_FLAGS and Makefile ASYNC_LDFLAGS→JSPI_LDFLAGS,
kicadCollabFiberBusy→kicadCollabBusy (embind + web + tests),
collab_common.h fiber*→apply*/coroutine naming, asyncifySignatures→
wasmTrapSignatures (lists byte-identical).
Tests: the two remaining vacuous [wx-asyncify]/fiber-resume-refused
asserts re-keyed to live JSPI beacons; eeschema-load's failure message
no longer sends the developer to a deleted script; wait-beacons' dead
families/parser deleted; lane-0 legacy-glue guards removed (lane 0 is
unconstructible); the embind test.fail re-gated with the JSPI reason
(plain embind invokers cannot suspend — verified still failing);
lint-determinism now scans tests/jspi (166 files clean);
eeschema-collab local-move gated to chromium (~50% flaky on FF even
solo; pcbnew twin covers both engines).
Docs: DEBUG.md rewritten as the JSPI debugging guide; build.md
describes the single-phase build; docs/features/async/README.md
banner-marked historical and repointed at the NEW
23-jspi-runtime.md (current architecture: export census, turnstile,
libcontext ownership + refusal contract, embind call shapes, the
em-pthread service-wrapper trick, exception policy, known gaps).
Gates on the cleaned tree: test:e2e 725 passed / 0 failed (after the
quiescence-probe fix; the 3 other reds were verified contention flakes
solo-green or the documented FF gate), web 76/0, jspi 18/18 both
engines, vitest 295/295 + 17/17, all lints green, live-app census
clean.

Phase 8 in the parent repo. Deleted: asyncify-scheduler.js, apply-asyncify.sh,
apply-finalize.sh, inject-dyncall-shims.sh, asyncify-imports/removelist.txt,
the wasm-opt/finalize stub pair, scripts/binaryen-hoist-pass/ (the fork stays
a dormant submodule; removal is a follow-up), bench/wasm-opt-bench.sh (README
marked historical), wasm/shims/context_sleep.cpp, and the sched-context
harness app + Makefile targets.
PCBJAM_ASYNC_BACKEND is gone: build-wx-wasm.sh hardcodes the jspi stamp
(still force-cleans pre-migration trees), build-kicad-target.sh gives editors
the JSPI link surface and the CLIs nothing (they pin ASYNCIFY=0), the stub
dance is replaced by an unconditional .real-restore, build-wasm-test.sh lost
its whole post-link loop, docker/build.sh's postprocess is the ENV shim only,
and Makefile.wasm links every app JSPI with the scheduler shim as a tracked
prerequisite. pcbjam_async_policy.h keys on __EMSCRIPTEN__.
jspi-scheduler.js: wxWasmMainLoopPump dropped from the wrap census (the
export died with the D5 detach); inert [TRACE] instrumentation removed.
CI: wasm-build.yml rewritten for the single-cache pipeline (one output cache
keyed on compile inputs; post-processed bytes cached after the shim);
opt_level input removed from both callers. wasm-cache-hash.mjs inputs now
cover patch-env-shim.mjs + jspi-scheduler.js + jspi-exports.txt.

docker/build.sh "all" now includes kicad_tools (finalizes in-container, so
it never contends with the editor's wasm-opt critical path); .ci-cache-epoch
bumped — the cached FINAL output set changes. wasm-build.yml gains the
corpus-lint + CLI-contract gate step (run_tests leg): with the artifact now
built in CI, the skip-when-unbuilt scripts bite. Release runs
(upload_output) start shipping kicad_tools in the wasm-output artifact —
the closed repo's runner-image workflow consumes it from there.

An idle builder keeps the Docker Desktop VM ballooned: each per-worktree
compose project carries its own ${KICAD_DOCKER_MEM:-32G} cap, build.sh left
the container running afterwards ("interactive use"), and two forgotten
builders plus the VM's page-cache/high-water behavior read as ~56 GB of host
RAM during a ~20 GB build.
stop_builder() now runs from the EXIT trap on every path (success, failure,
Ctrl-C — both the sequential and the pipeline-mode trap). The container is
pure scaffolding — all caches live in the named volumes and `up -d` restarts
it in seconds — so stopping costs nothing. KICAD_KEEP_CONTAINER=1 restores
the old keep-running behavior for interactive debugging; docker/shell.sh is
unaffected (it does its own `up -d`).
Verified live: the full `all --build-deps` run on main left zero containers
running at exit.

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).

The Binaryen wasm-opt shrink after Asyncify was the only -O2 in the
pipeline: -O2 by default (local + tag release) but -O1 in main CI. The
C++/wx/deps compile is already -O1 everywhere (DEBUG_BUILD defaults to 1;
nothing passes --release in CI/release). Pin the tail to -O1 too:
- apply-asyncify.sh: BINARYEN_OPT_LEVEL default -O2 -> -O1
- release.yml: opt_level -O2 -> -O1 (demo now ships -O1)
- ci-ubicloud.yml / wasm-build.yml / docker/build.sh: refresh stale -O2 comments
Because both callers now build at -O1, the FINAL cache key converges, so a
tag release FINAL-cache-hits main's build and skips the asyncify-tail
rebuild entirely (previously the ~1-2h -O2 wasm-opt was rerun per release).

The emscripten glue's `var ENV = {};` never merged Module.ENV, so boot.ts's
Module.ENV.KICAD_TRACE was a silent no-op — and since environ_get on a pthread
proxies to the main thread, the app/UI thread's getenv read the (empty) main
ENV. Net: KICAD_TRACE never arrived and every KI_TRACE was a no-op.
scripts/common/patch-env-shim.mjs post-processes each generated <app>.js to
merge Module.ENV into ENV (idempotent; runtime no-op when unset), wired into
docker/build.sh's per-app host post-process next to the dyncall-shim inject.
Replaces a fragile manual glue edit re-applied after every build. Verified:
symbol-editor eager load now emits KI_TRACE_SYM_CHOOSER fatLoad timing.

The native-EH migration pointed apply-finalize.sh at emsdk's bundled
wasm-emscripten-finalize (${EMSDK:-tools/emsdk}/upstream/bin), which exists on a
dev machine (tools/emsdk persists from a prior build) but never on the ephemeral
CI host — emsdk lives only inside the Docker image, and nothing on the host
post-process path provisions it. So the host post-process died at finalize for
every app once the binaryen-SHA cache re-key forced it to actually run. (Not the
missing-ninja theory — ninja was installed; the run never reached the wasm-opt
build, which is downstream of finalize.)
Finish the "Binaryen submodule everywhere" migration: build-wasm-opt.sh now also
builds wasm-emscripten-finalize, and apply-finalize.sh takes it from that build
(next to wasm-opt). The host post-process is now emsdk-free (dyncall=node,
finalize+asyncify=submodule v130) and finalize/wasm-opt share one Binaryen
version (previously finalize was emsdk's v121, wasm-opt the submodule's v130).
get-wasm-opt.sh stays for bench only; dropped it from the wasm cache key and
added build-wasm-opt.sh.
Also surface the from-source Binaryen build as a "Build Binaryen" stage in
build-monitor.sh (it had no marker), emitted at the pipelined pre-warm sites.
Validated: a clean from-scratch `docker/build.sh calculator --build-deps` (deps +
compile + finalize via the submodule binary + asyncify + -O2) succeeded
end-to-end; finalize resolved to build-wasm/tools/binaryen-hoist-build/bin.

Replace the legacy Emscripten JS-exceptions model with native wasm-EH (legacy
encoding) across the whole build, keeping Asyncify coroutines working via a
from-source Binaryen --hoist-cpp-catches pre-pass. Net result: native-EH is the
only build mode, the 3D viewer is on by default, and pcbnew shrinks substantially.
Highlights:
- Binaryen submodule everywhere + --hoist-cpp-catches integration in apply-asyncify;
post-link Asyncify covers every app wasm (not just standalone test wasm).
- Build deps (incl. OpenCASCADE without OCC_CONVERT_SIGNALS) and all KiCad apps
with -fwasm-exceptions; emscripten_sleep added to the post-link asyncify-imports.
- libcontext fiber entry wired under native exceptions; while-loop main loop +
currData shim injected into all wx apps.
- Native-EH collab apply fixed: DEBUG-define the embind TU + match all out-of-CMake
C++ TUs' ABI flags to the core, fixing the vtable-layout skew / mis-dispatch.
- 3D viewer enabled by default (real raytracer linked, not the stub).
- Retire the EH-spike scaffolding; flip the asyncify-races ablation pins to
shim-redundancy pins (native-EH stays clean with the legacy shims ablated).
- Fix the asyncify-races quiescence check to not require Asyncify.currData==0:
under the native-EH per-frame-yield top loop the main stack is asyncify-suspended
every frame, so currData legitimately churns (a freed-but-not-yet-nulled buffer,
not a leak). Refresh the pcbnew toolbar screenshot baseline for the new kicad.
- CI: drop the obsolete binaryen_version input/env (the build uses the binaryen
submodule fork's wasm-opt, not a version download); key the wasm-output cache on
the binaryen submodule SHA instead.
Bumps the wxwidgets + binaryen submodules to their squashed feature commits.
Validated green: all 7 apps native-EH (real 3D in pcbnew); KiCad e2e 63/63
Firefox + Chromium (3D viewer renders); wx 336; coroutine 34/34 both engines;
asyncify 7/7 both engines.

The container compile produces an OPT-INDEPENDENT base wasm; the only opt-dependent work is the final 'wasm-opt -O$LEVEL' shrink in apply-asyncify (host post-process). Splitting the build at that boundary lets CI cache the expensive compile ONCE (shared across -O1/-O2) and re-run only the asyncify/-O tail per opt level.
--compile-only: in-container compile → output/ base wasm (no post-process). --postprocess-only: pure host dyncall+finalize+asyncify+wasm-opt -O on the existing base (no container; get-wasm-opt self-provisions Binaryen). Default 'both' is unchanged. Phase flags are extracted before ARGS so they are not forwarded to inner build-<app>.sh. bash -n + shellcheck -S error clean; extraction unit-checked incl. the empty-after-filter case.
Enables the two-tier CI cache (opt-independent base + opt-specific final) so an -O2 demo release reuses main's compiled base and only runs asyncify+O2.

Builds KiCad's 3D viewer for the browser (opt in with BUILD_3D_VIEWER=ON) and
wires up the legacy-GL emulation it needs.
- build-kicad-target.sh / docker/build.sh: BUILD_3D_VIEWER →
-DKICAD_BUILD_3D_VIEWER_WASM=ON + -sLEGACY_GL_EMULATION + the GL js-library.
- wasm/shims/gl_immediate_shim.js: display-list emulation (record/replay board
layers), fixed-function + GLU stubs, throw-guards for unsupported pnames, and
per-context GLImmediate init for the viewer's SECOND WebGL context.
- tests/kicad/3d-viewer.spec.ts + utils/pcbnew-ready.ts: open View → 3D Viewer.
- bumps the kicad submodule (EMSCRIPTEN-guarded GL changes).
WIP: the viewer window + UI render and geometry draws (glError=0x0), but the
board is not yet visibly rendered — GLImmediate's FFP shader program isn't
linked on the viewer's 2nd WebGL context. Full status + next steps in
features/feat/add-3d-view/notes.md.

Headless node-WASM CLI that converts legacy symbol libraries to .kicad_sym via
SCH_IO_MGR::ConvertLibrary. Adds wasm/cli/sym_convert_main.cpp + sym_convert_pre.js
(in-memory localStorage + wxConfig JS-hook shim), registers sym_convert as a
docker/build.sh app (own kicad-sym_convert tree, real wasm-opt/finalize in-container,
skip host postprocess), and bumps the kicad pointer for the matching target.

The canvas (wxUniversal) mode is gone (wxwidgets submodule); remove every
piece of side-by-side plumbing so there is exactly one build and one test
flow:
- scripts/build-wxuniversal-wasm.sh -> scripts/build-wx-wasm.sh; no
--dom/--enable-universal; builds into build-wasm/wxwidgets
- build-wasm-test.sh: no DOM_BUILD / apps-dom rsync mirror / PORT=dom;
apps build straight into tests/apps (Makefile.wasm PORT conditionals
collapsed; wx.js + wx-dom.js always pre-js)
- docker/build.sh, build-kicad-target.sh, env.sh: WX_PORT / -dom /
-universal suffixes removed; kicad builds to kicad-<app>, outputs to
output/; wx.js/wx-dom.js copied from the real source path
(/workspace/wxwidgets/build/wasm — the old build-wasm path never
existed and silently failed)
- setup-kicad-wasm.sh: single target dir; the perl wx-dom.js injection is
gone — the 7 checked-in kicad pages now reference wx-dom.js directly
- playwright configs serve apps/; fixtures drop the test-results/dom and
logs/wxwidgets/dom namespacing; boot.spec asserts wxDomPort
unconditionally; pcbnew.spec uses one reference image;
appearance.spec assertions unconditional
- compare/update-baseline-screenshots.sh: --port removed
- tests/gal-regression/wasm/Makefile: links build-wasm/wxwidgets and
carries wx-dom.js as a second pre-js — the gal-webgl suite (30 specs)
now actually builds and runs here (it needed host-side boost+glm via
scripts/deps; the bundle had been missing, timing the whole spec out)
- tests: clickCanvas() dispatches via page.mouse (DOM widgets
legitimately cover the canvas; locator actionability refused the
click); the comprehensive spec drives wxChoice through its native
<select> (browser-owned popup cannot be coordinate-clicked)
- docs: README/CLAUDE.md/build.md script names and dirs;
features/wx-dom-port README reframed (DOM is THE port), visual-notes
bugs 26-28; FindwxWidgets.cmake config label drops 'wasmuniv'
- wxwidgets submodule -> 9dbacc9448 (DOM-only port, fork diff shrunk)
Gate: full wx e2e suite 292 passed / 1 skipped / 0 failed — first run
ever with the gal-webgl specs green (28 scenarios + load + sequential).

Upstream 680edd's pipelining moved dyncall/finalize/asyncify into

Pipeline: lexer generation (pcbcommon) ordered before the embind
pre-compile — a fresh-build-tree chicken-and-egg any new volume would
hit (generated pcb_lexer.h was included via -I${KICAD_BUILD}/common
before anything generated it). DOM flavor outputs flow through the
host-mounted output/dom/. pcbnew e2e on DOM: editor loads fully (layer
manager, toolbars, WebGL viewport, registry metrics), draw-lines test
passes; the header pixel-reference assertion fails as expected (native
DOM styling vs univ pixels) — port-aware references pending.

WX_PORT=dom flows host → docker container → build scripts:
build-kicad-target.sh selects wxwidgets-dom + kicad-<app>-dom trees;
docker/build.sh passes the env through, copies outputs to output-dom/
incl. wx-dom.js, and post-processes there; build-wxuniversal-wasm.sh
honors WX_PORT and accepts --no-clean again (the kicad pipeline calls it
with that flag — Phase 1's stricter parser had broken the canvas docker
path). setup-kicad-wasm.sh syncs DOM bundles into tests/apps-dom/kicad
and injects the wx-dom.js script tag into the kicad pages;
playwright-kicad.config.ts serves apps-dom under WX_PORT=dom.

Three orchestration fixes, validated end-to-end on the Hetzner ccx53
(run 27280051992, 1h14m41s vs 4h05m baseline, e2e identical):
- docker-compose CPU/memory caps were hardcoded to dev-Mac defaults
(10 CPUs / 32G); now env-tunable via KICAD_DOCKER_CPUS/KICAD_DOCKER_MEM
(CI exports nproc/110G — the 32-core runner was compiling on 10 cores).
- docker/build.sh: split build_app into compile_app (container) +
postprocess_app (host-side dyncall shims + finalize + asyncify + -O2)
and added KICAD_PIPELINE=1 mode that overlaps each tool's host-side
wasm-opt with the next tool's container compile (max 2 concurrent
postprocesses — pcbnew -O2 peaks ~34G RSS). Also: comma-separated app
lists for cheap pipeline repros.
- get-wasm-opt.sh: Binaryen default 121 -> 130 (fixes the v121 -O2 lock
convoy, ~9x) and BINARYEN_BUILD_FROM_SOURCE=1 support: the official
x86_64-linux release tarballs (Alpine/musl, no LTO, assertions on) run
asyncify 4x slower than a stock gcc -O3+LTO build with sha256-identical
output; self-build takes ~5 min and is instantly repaid.

Brings up KiCad's pagelayout_editor (drawing-sheet editor) in the
browser, to roughly the same "boots, canvas visible, partially usable
in-session" level as the existing pcbnew/eeschema/calculator ports.
Build:
- docker/build.sh: add pl_editor to the unified app dispatch (case,
subdir map, all-loop).
- scripts/kicad/build-kicad-target.sh: add pl_editor to the case;
upstream target name pl_editor under source subdir pagelayout_editor.
- scripts/kicad/build-pl_editor.sh: 7-line thin wrapper matching the
pcbnew/eeschema/calculator pattern.
- tests/scripts/setup-kicad-wasm.sh: copy_app pl_editor.
App glue:
- wasm/stubs/nl_pl_editor_plugin_stub.cpp: no-op SpaceMouse plugin so
pl_editor_frame.cpp's NL_PL_EDITOR_PLUGIN symbols resolve. Mirrors
nl_pcbnew_plugin_stub.cpp.
- tests/apps/kicad/pl_editor.html: browser shell. preRun creates
/home/kicad and FS.chdir there so file dialogs land somewhere
friendly instead of MEMFS root (/dev/, /proc/, etc.).
E2E coverage:
- tests/kicad/pl_editor.spec.ts: 5 tests — smoke (canvas, no abort),
wizard, File menu has Open/Save As, file-dialog folder-navigation
regression, canvas + toolbar metrics.
- tests/e2e/filedialog-folder-nav.spec.ts: wxWidgets-level twin of
the regression test (exercises the underlying widget directly via
the standalone filedialog_test app).
Submodule bumps:
- kicad → feature/pl-editor (WASM gating in pagelayout_editor's
CMakeLists + navlib stub).
- wxwidgets → feature/pl-editor (wxGenericFileDialog::OnOk navigates
into selected directories; wasm/mouse.cpp emits wxEVT_LEFT_DCLICK
via timestamp-based double-click detection — the latter benefits
every wxWidgets-WASM app).
See features/pl-editor/ for the design doc + per-repo diff patches.

Convert the calculator port (commit 0464470) from the parallel/copy-paste
pattern to the dispatch pattern used by pcbnew + eeschema.
- docker/build.sh: <app> is now required (no pcbnew default); missing,
unknown, and --help paths all print "pcbnew | eeschema | calculator | all".
Adds calculator to build_app() via kicad_subdir_for() (pcb_calculator
inner subdir, calculator.* output basename). Also fixes the
EMSDK=/emsdkkicad-wasm-builder typo that snuck in during the calc merge.
- scripts/kicad/build-kicad-target.sh: accepts calculator; introduces
KICAD_TARGET (pcb_calculator for calc, == APP_NAME otherwise) used for
the make target, embind include path, and final-log line.
- scripts/kicad/build-calculator.sh: 305-line copy of build-pcbnew.sh
collapsed to a 7-line wrapper around build-kicad-target.sh.
- tests/scripts/setup-kicad-wasm.sh: copy_app calculator added with the
same pcb_calculator subdir mapping for the docker-volume fallback path.
- tests/package.json: test:calculator* routed through the shared
playwright-kicad.config.ts kicad/calculator.spec.ts (mirrors eeschema).
- Delete: docker/build-calculator.sh, tests/scripts/setup-calculator-wasm.sh,
tests/playwright-calculator.config.ts.
Bumps wxwidgets d1d1627 -> 6fb2eac (origin/wasm-port). The new sha includes
"unic/combobox: add GetCurrentSelection() inline default" which calc's
kicad/pcb_calculator/widgets/unit_selector.cpp needs to compile. Without
this bump the unified dispatch would expose calc as a buildable target but
the build itself would fail. Verified: build.sh all completes clean across
all three apps; pcbnew/eeschema e2e pass; calc compiles and launches (test
stability separate from this refactor).

Emscripten 4.x removed dynCall_* WASM exports, breaking asyncify
rewind through indirect calls (modal dialogs, event handlers).
Generate JS shims that track Asyncify.exportCallStack and register
in wasmExports so doRewind can find them.
Also fixes empty callback functions ((() => {})) generated by
Emscripten 4.x + pthreads for HTML5 events, pthread entry,
sighandler, async timer, and main loop callbacks.
Build pipeline improvements:
- Stub wasm-opt/finalize in Docker (RAM limits), run on host
- Add setup-emsdk.sh for reproducible Emscripten setup
- Simplify env.sh and version management

Replace timestamp-based rsync + touch with checksum-based sync:
- Use --checksum to only transfer files with actual content changes
- Remove touch mechanism that caused all files to appear "newer"
- Exclude .git, logs, .idea, node_modules from sync
The old approach created a perpetual timestamp mismatch:
1. rsync -a preserved host timestamps
2. touch set container timestamps
3. Next build saw mismatch → transferred everything → touched again
With --checksum mode:
- Changed files: transferred with current time → rebuilt (correct)
- Unchanged files: not transferred → keep timestamp → no rebuild (correct)
Tested scenarios:
- Consecutive builds: ~2 min (cached) vs ~6+ min (was full rebuild)
- Modified wxWidgets file: only that file recompiled
- Modified KiCad file: only that file recompiled

The KiCad WASM build was freezing during initialization due to a pthread
deadlock. When hardware_concurrency() > PTHREAD_POOL_SIZE, new Web Worker
creation requires the event loop, but the main thread busy-waits blocking it.
Changes:
- Use navigator.hardwareConcurrency for PTHREAD_POOL_SIZE in KiCad build
- Add threadpool test to reproduce and verify the fix
- Add single-target build support to build-wasm-test.sh
- Default docker/build.sh to -j 10 for faster builds
