A clean dependency build failed immediately at the GLM step with
`unzip: command not found`. build-glm.sh extracts glm-0.9.9.8.zip with unzip,
but the Ubuntu-based image (introduced when the emsdk image was replaced) never
installed it. Add unzip to the apt-get list.
Verified: GLM, zstd and protobuf now build and stamp, and the deps build
proceeds into boost.

The wxWidgets autoconf build inside Docker failed with `emmake: command not
found` on a clean build, while the KiCad CMake build survived (CMake caches the
absolute compiler path). Two compounding causes:
1. `docker compose exec` bypasses the ENTRYPOINT, so it never sourced
emsdk_env.sh and EMSDK was unset. env.sh then fell back to the local
tools/emsdk.
2. The entrypoint's rsync from the host bind mount excluded only build-wasm and
output, so the host's macOS-arm64 tools/emsdk got copied over the container's
Linux emsdk. The macOS Mach-O python can't exec on Linux, so
`emsdk construct_env` failed ("Exec format error") and emcc/emmake never
landed on PATH.
Fixes:
- Set `ENV EMSDK=/emsdk` in the image so every process (including
`docker compose exec`) resolves env.sh's EMSDK branch to the container's own
emsdk and never falls back to tools/emsdk.
- Exclude `tools/emsdk` from the entrypoint rsync so the host emsdk can no
longer leak into the container.
Validated with a clean wxWidgets build (`build-wxuniversal-wasm.sh --clean`):
reconfigures and compiles all 42 wx libs against /emsdk with no missing-tool
errors.

Investigation scaffolding for the Chrome-only KiCad coroutine renderer crash.
Adds isolated reproduction probes exercising the coroutine/Asyncify/fiber layer
under KiCad-like conditions, runnable in BOTH Firefox and system Chrome.
- tests/playwright-coroutine.config.ts + test:coroutine:firefox|chrome npm
scripts: run the coroutine specs in Firefox AND system Chrome (the old e2e
config only used bundled Chromium, which never reproduced the crash).
- tests/apps/standalone/coroutine-pthread/: no-wx + pthreads reproduction probes
(fiber-in-main, nested invoke_/dynCall boundaries, RunMainStack, embind,
main-loop/rAF activation) + worker_dom_stub.js for wx+pthreads builds.
- tests/apps/Makefile.wasm: coroutine-pthread{,-main,-nested,-nested-ex,-wx,
-embind,-mainloop} targets.
- scripts/common/shims/diagnostics.js: add EM_ASYNC_JS handleSleep enter/wake
tracking (DIAG_SLEEP) to detect nested-async at the crash.
Findings (details in research notes): every isolated factor so far — direct /
nested / RunMainStack fiber, wx event loop + all 13 scenarios incl EM_ASYNC_JS,
pthreads, and main-loop/rAF activation — runs CLEAN in system Chrome. The
coroutine/Asyncify layer is exonerated; GL/WebGL is the remaining untested factor
(next). The reliable FF-pass/Chrome-fail repro is still the KiCad pcbnew e2e.

The shim bound bare dynCall_* names to JS getWasmTableEntry() calls, bypassing
the asyncify-instrumented dynCall_* wasm trampolines that -sDYNCALLS=1 provides.
That broke Asyncify unwind/rewind through indirect calls -> "indirect call
signature mismatch" (caught every frame in Firefox; fatal renderer crash in
Chrome). Bind the bare names to wasmExports["dynCall_<sig>"] instead.
Result: the PCBnew "select draw lines" e2e is green in Firefox (tool selects and
draws, zero page errors). Dropped the fiber-stabilization block, the shipped
diagnostic block, and the exportCallStack JS hack (all compensated for the wrong
binding); shim shrank 521 -> ~250 lines.
- scripts/common/inject-dyncall-shims.sh: orchestrator only; injected JS extracted
to scripts/common/shims/
- scripts/common/shims/dyncall-binding.js.tmpl: per-signature binding template
- scripts/common/shims/handlesleep.js: nested-Asyncify handleSleep fix (#9153)
- scripts/common/shims/diagnostics.js: logging-only, opt-in via SHIM_DIAGNOSTICS=1
- tests/package.json: add test:kicad:firefox / test:kicad:chrome scripts
Known issue (tracked separately): Chrome still renderer-crashes on the first
coroutine resume. Asyncify.doRewind replays the deep main-context call stack and
exceeds V8's execution-stack limit (Firefox tolerates the same wasm). Proper fix
is JSPI.

Main-repo side of a multi-part WIP covering the KiCad WASM tool-selection
and nested-Asyncify work. Submodule commits are in kicad@f6e9239aaa
(libcontext hygiene) and wxwidgets@bb80f91e8b (auibar registration +
dialog diagnostics).
## scripts/common/inject-dyncall-shims.sh
Wrap Asyncify.handleSleep / allocateData to save-and-restore Asyncify.currData
around each EM_ASYNC_JS sleep. This fixes the nested Asyncify collision where
a fiber swap that fired during a modal's event loop clobbered currData, and
the modal's later doRewind used the fiber's buffer and hit "RuntimeError:
index out of bounds". Root cause documented as Emscripten Issue #9153
(wontfix upstream).
Diagnostic-rewind logging (forcedBottomOfCallStack, callStack traces) is
retained to help future debugging of Asyncify state corruption.
## tests/
- tests/playwright-kicad.config.ts: add `channel: 'chrome'` for the
chromium project so --project=chromium --headed uses system Chrome
(real GPU) instead of SwiftShader on ARM Mac. Also switch trace to
retain-on-failure + screenshot on-failure for easier E2E debugging.
- tests/kicad/pcbnew.spec.ts: replace `tool.checked` assertions with a
label-suffix check (`[checked]`) since our auibar registration encodes
checked state in the label (no schema change to the registry).
- tests/apps/Makefile.wasm: add `coroutine-nested` build target + include
it in the all: list.
- tests/apps/standalone/coroutine/: kicad_coroutine_harness.h + test app
reproducing KiCad COROUTINE semantics against real libcontext.
- tests/apps/standalone/coroutine-nested/: nested_test.cpp reproduces the
EM_ASYNC_JS-modal + fiber-swap nesting bug in isolation. 8 scenarios
from baseline_modal_alone through nested_fibers_inside_modal.
- tests/e2e/coroutine.spec.ts + coroutine-nested.spec.ts: Playwright specs
that load the standalone apps and assert all case cases pass via
[COROUTINE_TEST] SUMMARY log parsing.
## research/ and features/browser-tools/
Three background docs capturing the investigation trajectory:
- features/browser-tools/0001-kicad-wasm-tool-activation-investigation.md
Early investigation: why tools don't activate; initial dynCall-empty-
callback hypothesis.
- features/browser-tools/0002-wasm-coroutine-deep-dive.md
Deep dive on Asyncify internals, fiber API, QEMU's coroutine-wasm
reference implementation.
- features/browser-tools/0003-wxauitoolbar-registration-fix.md
The narrow fix: why wxAuiToolBar needs a registration block, where to
add it, what the fallback plan is.
- research/threading_1.md: corrected root-cause analysis after reading
runtime logs — nested-Asyncify currData collision, Emscripten #9153.
- research/threading_2.md: extended research on alternative approaches
(JSPI/WasmFX/state-machines) and why they don't help here.
## Submodule pointer updates
kicad: f6e9239aaa (wip: libcontext WASM hygiene cleanup)
wxwidgets: bb80f91e8b (wip: wxAuiToolBar element-registry registration +
dialog diagnostics)
## Open threads not yet in scope
- Firefox/Chrome divergent behavior: "indirect call signature mismatch"
traps in Firefox vs renderer crash in system Chrome (tracked in
plans/peaceful-hugging-pnueli.md and the research docs).
- E2E pixel-diff for Draw Lines fails because the test's diff region does

The Docker build used emscripten/emsdk:4.0.2-arm64 as base image but
env.sh couldn't find emsdk there, installing a second copy. The build
then applied wasm-opt/finalize stubs to the wrong emsdk (hardcoded
/emsdk/), so the real wasm-emscripten-finalize ran in Docker and got
OOM-killed.
- Use ubuntu:22.04 base with emsdk installed from source at /emsdk/
- Make stub paths dynamic via $EMSDK instead of hardcoded /emsdk/
- Skip local emsdk install in env.sh when $EMSDK is already active

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

Emscripten with pthreads generates empty arrow functions `{}` for callback
paths it assumes won't be used. However, when registering HTML5 events from
the main browser thread, targetThread is 0 and the direct call path IS taken.
This fix post-processes the generated JS to replace empty callbacks with
actual dynCall invocations for:
- HTML5 event callbacks (dynCall_iiii) - 7 instances
- pthread entry points (dynCall_ii) - 1 instance
- Signal handlers (dynCall_vi) - 1 instance
- Async timers (dynCall_vi) - 1 instance
Also improves build logging to show completion status and exit code.

Migrate WebGL GAL implementation from tests/gal-regression/wasm/webgl/
to kicad/common/gal/webgl/ and kicad/include/gal/webgl/.
This integrates the WebGL GAL properly into KiCad's build system:
- Update test Makefile to use sources from kicad/ instead of local copies
- Update build scripts for new source locations
- Add test-gal-webgl.sh script for running WebGL regression tests
- Update Docker to Emscripten 4.0.22

Establish baseline screenshots for WebGL GAL implementation before
migrating it from test harness into KiCad's build system.
Current status: 7/27 scenarios passing (20 different from native):
- Alpha-blending: FIXED (blending now correct)
- Transform-API: EXCLUDED (dead code)
- Other scenarios: Work in progress
This baseline will be used by test-gal-webgl.sh to detect regressions
during the migration process. Goal is to preserve current rendering
fidelity while integrating WebGL GAL into KiCad source tree.

Alpha-blended shapes were rendering nearly invisible due to incorrect
blend function configuration in two places:
1. FBO rendering (webgl_gal.cpp): Changed to glBlendFuncSeparate to handle
RGB and alpha channels independently. Alpha channel now accumulates
coverage correctly (prevents it from staying near 0.0 when rendering
with alpha=0.5).
2. Compositor (webgl_compositor.cpp): Changed from premultiplied alpha
blend (GL_ONE, GL_ONE_MINUS_SRC_ALPHA) to straight alpha blend
(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA) since our FBOs use straight alpha.
Also marked Transform() as dead code with explanation - never called in
KiCad and has no effect even in native OPENGL_GAL.
Result: Alpha-blending scenario now renders correctly with proper color
mixing for overlapping shapes.

- Use .gl-canvas selector (same as individual tests)
- Increase timeout from 50ms to 100ms
- This fixes blank screenshots in full test runs
2. Fix test-gal-regression.sh comparison:
- Normalize PNG format before comparing (flatten + sRGB TrueColor)
- This handles RGBA vs RGB and palette differences
- gal-basic-lines now passes comparison (0.34% different)

WebGL 2.0 / OpenGL ES 3.0 requires a Vertex Array Object (VAO) to be
bound before setting vertex attributes. Desktop OpenGL has a default
VAO (VAO 0), but WebGL 2.0 does not.
Changes to GPU_MANAGER:
- Add m_vao member variable to store VAO handle
- Create VAO in SetShader() when GL context is available
- Bind VAO before glVertexAttribPointer calls in EndDrawing()
- Unbind VAO after rendering completes
- Delete VAO in destructor
This fix enables actual rendering output in WebGL. Without a VAO,
glVertexAttribPointer silently fails and no geometry is drawn.

Additional API coverage in existing scenarios:
- Flush() in test harness
- SetFlip(), SetRotation() in screen-transform
- SetDepthRange() in depth-testing
- GetGridPoint() in grid-native
New stub files:
- kifont_stub.h: STROKE_GLYPH factory functions for letter glyphs
- bitmap_base_stub.h: Test pattern generators (checkerboard, gradient)
Note: Bitmap scenario shows empty panels - DrawBitmap uses legacy OpenGL

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
