f6171a7d34Traced, not inferred: TOOL_MANAGER::RunSynchronousAction spins
`while(synchronousControl == STS_RUNNING) { wxYield(); wxMilliSleep(1); }`
(tool_manager.cpp:370-371), and on wasm wxMilliSleep -> nanosleep ->
__wasm_main_thread_yield_ms is an ASYNCIFY PARK OF THE STACK IT STANDS ON —
in a loop, inside a tool body, with a nested wxYield() dispatch running on
top of the parked stack.
The case closes on its callers: they are exactly the tools whose specs died
at D-on — edit_tool_move_fct (move-with-m, presence-locks move),
sch_drawing_tools (draw wires), the drawing/edit tools behind draw-lines.
The pcbnew spec comments already described the symptom from outside ("the
asyncified pointer-move handler") without naming the park; this is it.
So doc 21's K7 "anywhere" class has ONE caller that blocks Phase D, and it
moves first: the wait must yield the owning context instead of sleeping in
place, with the atomic's transition marking it ready. Recorded with the fix
shape, the upstream-divergence question it raises, and the gate that matters
(the KiCad suite's four canvas-tool specs — the harness has no
RunSynchronousAction and stays green either way).

Documentation Map
A central index of the documentation in this repo. The goal of the project is to build KiCad with WASM and run it in a browser.
Note: per-area
README.mdfiles stay next to the code they describe (they're linked below). Cross-cutting guides live underdocs/. Per-feature design notes live underfeatures/.
Start here
- Project README — overview, prerequisites, quick start, project structure
- CLAUDE.md — project/agent context and contribution conventions
Build
- docs/build.md — Docker-based KiCad WASM build system (two-phase build, outputs, memory)
- docker/README.md — Docker build environment, branch-specific containers, troubleshooting
- wasm/README.md — WASM compatibility layer (overrides/shims without patching KiCad)
Debugging & Asyncify
- docs/debugging/DEBUG.md — debugging guide: Asyncify stalls vs crashes, shim/codegen coupling, stub-bisection
- docs/debugging/learning.md — Asyncify + consecutive modal dialogs: the lock pattern
- docs/research/threading_1.md — deep dive: the Asyncify single-slot
currDatacollision bug and the fix - docs/research/threading_2.md — external research: JSPI/WasmFX/state-machine alternatives, QEMU analysis
Architecture
- wasm/README.md — WASM compatibility layer structure
- web/README.md — web app (create/open KiCad projects), tech stack, URL routing, WASM artifact serving
Testing
- tests/README.md — Playwright test infrastructure, element registry, logs, screenshots
- tests/WHATWORKS.md — wxWidgets-in-WASM feature coverage matrix and KiCad readiness
- tests/GL_README.md — Emscripten legacy GL immediate-mode quirks (color-per-vertex)
- tests/gal-regression/README.md — GAL visual regression suite (native OpenGL vs WebGL WASM)
Feature design docs
Per-feature design notes and porting records live under features/:
- web-init — web app spec
- schematic — eeschema WASM bring-up
- symbol-editor — symbol editor (eeschema kiface launcher)
- gerbview — Gerber viewer port
- pl-editor — page-layout editor port (incl. file-dialog usability fixes)
- browser-tools — tool-activation / coroutine deep dives
- fix-asyncify-O2-and-modal-promise-rejection — RTree wasm overflow bug investigation
