1) pcbnew/eeschema two-tab 'a local move propagates A->B' read the
pre-move baseline AFTER kicadCollabTestMoveFirst. The move is queued
through CallAfter + the apply coroutine, and the drain can land
between two consecutive page.evaluate round-trips — when it does
(~50% under CI load, reproduced locally with --repeat-each) orig
captures the ALREADY-MOVED position and the not-toBe poll waits on
itself. Wire tracing showed the bridge working: the moved delta
emits, nothing reverts. Fix: baseline from kicadCollabSnapshot
BEFORE the move. 12/12 green at --repeat-each=4 (was ~50% red).
2) jspi-firefox suites 404'd their harness modules: jspi-stack and
jspi-coroutine build via ad-hoc build.sh (Phase 3 Makefile wiring
TODO) which CI never ran. Wire both into build-wasm-test.sh (its
hash is already in the testapps cache key), and add the _pt pthread
variant that index.html?pt=1 loads but nothing built. jspi-firefox
8/8 green locally.

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.

- standalone wasm/collab/types.ts: the CollabItem/CollabDelta data shapes now
come from MIT @pcbjam/shared (collab-wire zod schemas) via re-export; the
RUNTIME adapter interface (CollabBridge) stays here. emptyDelta/isEmptyDelta
alias the shared helpers — reconciler untouched.
- tests/collab/browser-entry.ts: fix the import path stale since the repo
restructure (web/apps/frontend → web/standalone) — the collab bundle had been
silently unbuildable; its opts type now tracks startCollab's real signature.
- tests/kicad/*-collab.spec.ts: update KicadCollab.start calls from the
pre-ysync-0004 { channel, settleMs } API to { provider: { kind:
"broadcastchannel", settleMs }, room } — the drift the broken bundle hid.
Verified: pl_editor 2/2, eeschema 2 passed, pcbnew 7 passed (skips pre-existing);
shared 47 unit tests; both typechecks clean.

Thrust A — dialogs render top-left with OK clipped in the WEB app (not the
test harness): root cause was the React shell missing the .window /
.window-canvas CSS that wx.js relies on (it positions each dialog div via
inline left/top, which need position:absolute). Added the rules to
web/apps/frontend/src/index.css. Native draw-text now works end-to-end;
symbol/power choosers render (placing still blocked by absent libraries).
Thrust B — collab apply of a newly-added SCH_SHAPE trapped in KiCad core
(SCH_COMMIT::Push CHT_ADD -> GAL view->Add, an asyncify invoke_* mis-dispatch)
because doApply ran off a fiber stack. doApply now runs inside a COROUTINE so
it executes on a libcontext fiber, the same context native draws use; the add
dispatches correctly. Re-enabled the SCH_SHAPE converter (rect/circle). Added
thirdparty/libcontext to the embind include path (tool/coroutine.h needs it).
Verified two-tab: rectangle + circle drawn in tab A sync + render in tab B.
Extended eeschema-collab.spec.ts apply test with a SCH_SHAPE add.
All changes root-repo only; kicad and wxwidgets forks untouched.

Two things, both verified in the real web app (two-tab eeschema collab).
1. dynCall crash fix (all apps) — scripts/common/shims/dyncall-binding.js.tmpl.
Programmatic editor edits trapped with 'indirect call signature mismatch': the
asyncify-instrumented wasmExports[dynCall_<sig>] trampoline does call_indirect with a
stale type for some table indices (post-asyncify+O2) even though the table entry is
valid. Proven by patching the built js: at the trap getWasmTableEntry(index) SUCCEEDS
where the trampoline fails. Fix: the shim now catches the 'signature mismatch'
RuntimeError and falls back to getWasmTableEntry; the Asyncify unwind sentinel and real
exceptions re-throw, so instrumentation/unwind is untouched for normal calls. This
unblocks ALL programmatic edits, not just collab (e.g. eeschema SCH_ITEM::Move).
2. eeschema collab apply converters (wasm/bindings/eeschema_embind.cpp).
doApply now handles added-item construction (build the SCH_ITEM with the delta's uuid
via const_cast — as the s-expr parser does — + commit.Add) and richer SCH_LINE
serialization (start/end/layer) so wire edits reconstruct on the peer. Implemented for
SCH_LINE (wires) + SCH_JUNCTION; other types log 'no converter for added type' and are
skipped (next batch). eeschema re-enabled in the web app collab gate.
Tests: eeschema-collab.spec snapshot (green); apply/two-tab skipped — they no-op headless
because the e2e harness's kicadOpenFile returns false (OpenProjectFiles bails before
building the connectivity graph), so SCH_COMMIT::Push doesn't persist. Verified in-app.

eeschema's half of the Yjs collaborative bridge, reusing the generic reconciler /
BroadcastChannel transport unchanged. Zero kicad-fork change: native SCH_ITEM uuid +
native SCHEMATIC_LISTENER. All in the wasm layer (wasm/bindings/eeschema_embind.cpp).
Working (verified in the web app):
- kicadCollabSnapshot(): enumerate sch.Hierarchy() -> LastScreen()->Items() as
{id,type,x,y}; registers the listener on first call
- emit: SCHEMATIC_LISTENER subclass -> per-item delta via window.kicadCollab.onDelta;
fires on real SCH_COMMIT::Push (a real wire move broadcasts added/removed/changed)
Apply is a documented follow-up (gated off so a peer tab can't crash): SCH_ITEM::Move
traps with 'indirect call signature mismatch' when invoked outside a KiCad tool
coroutine (Asyncify+fiber+exception-trampoline). Modify/Clone/GetPosition all work;
only the virtual Move write traps. Fix direction: route apply through TOOL_MANAGER.
Also: build-kicad-target.sh now force-relinks when only <app>_embind.cpp changed (the
embind .o isn't a make dep, so new bindings silently vanished), and adds the
expected/rtree/fmt thirdparty includes the eeschema bindings need.
Tests: eeschema-collab.spec.ts covers snapshot (green); apply/two-tab skipped with the
blocker noted. WasmTool gates collab to pl_editor only until eeschema apply works.
