Gate results (single battery, scheduler-only): wx app battery +
asyncify + coroutine 363 passed / 3 skipped / 0 failed; full kicad
suite 138 passed / 30 skipped / 1 failed — the one failure is the
pre-existing local occ-probe glb case (predates D-1, unrelated).
Post-gate scrubs: vestigial 'startModal' removed from ASYNCIFY_IMPORTS
(tests/apps/Makefile.wasm) and env.startModal from
scripts/common/asyncify-imports.txt (the import no longer exists in any
wasm; both lists are boundary supersets so behavior is identical).
Stale comment pointers to the deleted legacy modal machinery updated.
Doc 20: D-1 work log added, status flipped to IN PROGRESS.

Doc 20 D-1, second slice: the injector now injects asyncify-scheduler.js
unconditionally — the WX_SCHEDULER=0 legacy opt-out, the
SHIM_DISABLE_HANDLESLEEP ablation skip, and the
SHIM_DISABLE_TRAMPOLINE_HEAL ablation skip are gone, and
scripts/common/shims/handlesleep.js is deleted (the scheduler subsumed
its capture/restore, fiber guard, and trampoline-heal duties in S2).
Comment-only scrubs point the remaining references at the scheduler
shim. .ci-cache-epoch bumped (shim/injector behavior changed).

Doc 20 D-1 (legacy runtime deletion), first slice: races_test_noheal /
races_test_nosleepfix pinned behavior of the legacy handlesleep shim,
which is being deleted — the pins now assert properties of a runtime
that no longer exists. Drops the two Makefile.wasm link+inject variants
(SHIM_DISABLE_TRAMPOLINE_HEAL / SHIM_DISABLE_HANDLESLEEP), the
shim-redundancy pin specs in asyncify-races.spec.ts, and resolves the
tests/README.md open task. The green battery still runs every scenario
against the scheduler glue.

asyncify-scheduler.js REPLACES handlesleep.js on WX_SCHEDULER=1 builds
(injector either-or): ports capture/restore, fiber consume-once/
quarantine guard, wake-window flags, recorder, trampoline heal — and
adds deferred wakes (a wake mid-transition queues and drains from a
clean macrotask) plus the N1 currData accessor (pure-JS writes need
scheduler authorization; strict mode throws; meta-tested). Gates:
races 9/9 with NO legacy shim (subsumption), coroutine 39/39,
wx-chromium 30/30, kicad trio 3/3 on the C-lane build.

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 asyncify single-slot work, executed red-green (full ledger:
docs/features/asyncify-arbiter/redgreen.md; decisions record:
docs/features/async/07-decisions-and-outcome.md):
- tests/apps/standalone/asyncify-races/ + tests/asyncify/ + dedicated
playwright config: 8 scenarios reproducing the KiCad asyncify failure
family with the kicad-faithful startup topology (pre-park fiber swap →
park throw through the live trampoline). Built in 3 variants; the
SHIM_DISABLE_TRAMPOLINE_HEAL / SHIM_DISABLE_HANDLESLEEP ablation builds
keep the historical hang and index-out-of-bounds crash reproducible
forever (mutation-style pins for the existing shims).
- scripts/common/shims/handlesleep.js: catch the "unwind" park sentinel
in the wakeUp path — when main's last pre-park suspension was a sleep,
the main-loop park throw escaped through that sleep's promise reaction
as an uncaught rejection (the calculator/gerbview console errors).
- scripts/common/inject-dyncall-shims.sh: SHIM_DISABLE_* ablation knobs.
- Spec tightening (the acceptance bar): 'uncaught exception: unwind'
tolerance DELETED from pcbnew/eeschema specs; load-pcb gained a hard
clean-console gate over 5 asyncify corruption signatures.
- wxwidgets pointer bump: modal LIFO resolvers, pump resolve-on-error,
sync clipboard IsSupported (014f67e6c1).
Final state: asyncify suite 7/7, wx e2e 291/292 (1 skip), KiCad e2e 40
passed / 2 skipped with ZERO corruption signatures in any log across all
six apps.
