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.

The Y.Doc is the source of truth for the FILE, but both live wires wrote
KiCad's CLIPBOARD dialect — a lossy, paste-oriented format. Every
difference was permanent, unfixable drift.
- pcbnew: serialize footprint blobs with CTL_FOR_BOARD, not CLIPBOARD_IO's
CTL_FOR_CLIPBOARD, which emitted (version)(generator)(generator_version)
inside every (footprint …). Keep (locked yes).
- eeschema: aForClipboard=false — clipboard mode collapsed every symbol's
(instances … (path "/sheet")) to (path "").
- Re-supply (version) at PARSE time only (withFootprintVersion): the token
is invalid file content but load-bearing on decode — without it the
parser starts at m_requiredVersion=0 and stamps (hide yes) on every
mandatory field.
- FOOTPRINT copy ctor: restore mandatory-field uuids (EDA_ITEM::operator=
keeps the target's const m_Uuid, so Clone() rerolled all four).
- drift: classify order-only diffs as `reordered` — y-sexpr v2 reorders
legitimately; excluded from counts, report-worthiness and dedupe hashes.
Migration 0017.
- fpedit from eeschema: AsyncLoad()+BlockUntilLoaded() in initLibraryTree —
FACE_PCB starts lazily there and never preloaded its libraries.
Guards: wire-vs-file round-trip tests (pcbnew + eeschema),
fpedit-from-eeschema (verified red without the fix), symedit-from-eeschema.

Make the Playwright e2e + kicad suites deterministic so screenshot flake stops
tracing to timing races.
- Blind page.waitForTimeout -> condition waits (expect.poll, web-first
assertions, waitUntil) + readiness helpers (waitForWxApp, waitForCanvasApp).
Remaining sleeps are documented interaction dwells (annotated).
- Defensive "if element exists" branches -> loud asserts; label-fallback chains
-> normalized clickMenuItemByText. First-run wizard for/if loops removed by
seeding calculator/gerbview/pcbnew HTMLs.
- Screenshots: new stableShot(page, name) settles the render in-page (canvas
hash over rAF) then writes a raw PNG to test-results/ for the existing offline
gate (tools/screenshots vs baseline-screenshots). Replaces toHaveScreenshot,
which did inline compare + its own baselines and had decoupled the specs from
the real gate. scale:'css' pinned.
- retries: 0 in both configs.
- Guard: tests/tools/lint-determinism.ts (npm run lint:determinism) bans blind
sleeps / toHaveScreenshot / inline retries / swallowed catches in specs;
documented exceptions carry a marker. Rules in tests/TESTING.md.
Assertions, coverage, and renders unchanged (semantic-equivalence reviewed;
captures pixel-identical modulo inherent timer/timestamp/3d-raytrace variance).
Both suites green at retries:0 (e2e 340, kicad 92); ~35-61% faster.

- WasmTool: hard cutover to startKicadCollab (gates on
kicadCollabSnapshotItems; scalar reconciler no longer runs in the app)
- file-seed (ysync 0005 tie-in): empty rooms are seeded from the opened
file via fileToDoc/docToY (meta+layout+items — file recoverable from the
Y.Doc alone); populated rooms still adopt (seed-once unchanged)
- binding: gate UP applies until seed() — the provider's initial state
sync otherwise streams the full doc into an editor that already holds
the file (trapped eeschema's paste path in the real app)
- pcbnew blobForItem: footprints Format a uuid-corrected copy directly —
SaveSelection's copy regenerated mandatory-field uuids (FOOTPRINT copy
ctor assigns into fresh fields), breaking wire identity (rebuild)
- roundtrip.spec on the v2 items wire; new passing pcbnew
footprint-containment round trip (the 0004 containment win); full
fixture stays fixme on the tracked envelope-parse limit
- real-app two-tab emit verified for eeschema + pcbnew (see 0008 doc)
Full kicad suite: 45 passed, 3 skipped (known), 0 failed.

Block A save embind exports + the round-trip integration harness.
Save exports (wasm/bindings, GPL):
- pcbnew: kicadSaveBoard(path) via PCB_IO_KICAD_SEXPR::SaveBoard(GetBoard()).
- eeschema: kicadSaveSchematic(path) via SCH_IO_KICAD_SEXPR::SaveSchematicFile.
Saves GetCurrentSheet().Last() (NOT Schematic().Root()): the wasm open-flow
nests the opened doc under an auto-created project root, so Root()'s screen
holds only a child-sheet symbol, not the loaded items.
(pl_editor already had kicadSaveDrawingSheet.)
Round-trip harness (tests/kicad/roundtrip.spec.ts):
- load fixture → save (ORIG) → kicadCollabSnapshot → reload (fresh wasm) →
open empty → kicadCollabApply → save (REGEN) → assert sexprDiff(ORIG,REGEN).equal.
- Two separate pages (extract closed before rebuild opens) so the process-global
wasm heap frees between boots (pcbnew ~190MB). Open both sides from the same
filename (eeschema embeds it as the root Sheetfile property). pcbnew boots the
seeded pcbnew-collab.html (plain pcbnew.html's first-run wizard blocks boot).
- pl_editor + eeschema round trips PASS (lossless). pcbnew is test.fixme with
tracked apply-coverage findings (footprints/zones not reconstructed; segment
width + via size lost; fp_text→gr_text) — bridge gaps for follow-up, not test bugs.
