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.
