f734d700a2v0.1.24 in prod, doubly convicted the same morning: the Leonardo open crawled/hung (open:settled result=failed at the 60s escape, heap never past 256MB — every main-loop iteration runs INSIDE its yield-wake extent, so the "root-owned wake" scope matched thousands of legitimate nested coroutine Call/returns per open, each paying a deferred macrotask, throttled to ≥1s in a background tab), AND the Nano crashed 22ms after deferrals=1 fired. Harmful and insufficient: the fatal nested-rewind interleave and the benign bulk are observationally identical at this layer — no discriminator exists. Retired (second and final retraction, async/16 round 5). What stays shipped and clean: consume-once root suspensions, the internally-parked quarantine + laundering check, the flight recorder + beacons, the WSOD floor, the pendingSleeps leak fix (confirmed by pendingSleeps=[] in the Nano dump). The rare nested-rewind crash is ACCEPTED and fully observable until the structural fix — the design-B fiber-first runtime (async/06,12,13), where one scheduler owns every suspension and this interleave cannot exist. .ci-cache-epoch 6→7. Local: fiber 2/2 (one refusal beacon) + timer + firefox sweep 21 passed, chromium scenarios 11 passed/4 quarantine-skips, web fatal+follow 2/2.

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
