A review of the group-E fixes found 13 further defects; ten were introduced by
those fixes, two pre-existed and were merely relocated, one is deferred.
Services / transport
E-10 retireWorker synthesized no bg/exit frame, so sharedspice's s_bgRunning
mirror stayed latched true after a mid-run worker death: Run stayed
disabled and the promised fresh-worker restart was unreachable for the
whole session. Retirement now dispatches a synthetic controlled-exit
straight to the installed handler (never through dispatchEvt — a
fabricated frame must not touch the credit ledger). Driving the repro
exposed two further defects, both fixed here: a replacement worker
trapped on pre-init engine reads, and the rerun's cm_input_path/circ hit
that uninitialized engine before KiCad's validate() re-init (the native
flow assumes a crashed engine survives in-process — true for the dll,
false for a dead worker). Reads now answer their empty shapes pre-init,
writes lazy-init, and init is idempotent per worker engine.
E-19 dispatchEvt acked only AFTER handler(evt) returned, and the sharedspice
client deliberately rethrows non-trap errors — so each throw leaked one
unit of the 64-frame credit window until the stream died with a
misattributed "transport exceeded". The ack moves to a finally in both
service copies; the throw still propagates (the trap machinery needs it).
E-20 the oversize-line path promises to transfer the accepted prefix, but
with the window full that flush only DEFERS, and stopEventStream wiped
the deferred queue — losing the diagnostics that explain the failure.
The terminal notice now carries them as pendingEvents; both hosts
deliver them in order, unacked (the fatal frame is outside the credit
protocol).
E-21 the 30s prefetch deadline discarded every model already collected and
reported nothing. A caller-owned progress sink ships the partials and
the omission reaches the export report. (Awaiting the aborted collection
was rejected: an in-flight source fetch is not abortable — E-4's
original disease.) Plus a serving-candidate memo, so a .wrl ref served
by its .step fallback stops re-probing the miss on every export.
Scheduler
E-14 _terminalizeNativeTrap classified by message substring, so any plain JS
error QUOTING 'Aborted(' or 'out of bounds' permanently bricked a
healthy instance. Now structural only: instanceof RuntimeError plus a
duck-typed name check (verified in this build's glue that abort() throws
a genuine RuntimeError both pre- and post-runtime-init). Module.onAbort
now latches the gate — the authoritative notification, previously
ignored.
E-15 the shim half: _pumpResume gates on terminal (catching wakes already
queued at latch time) and resolveWait refuses on terminal WITHOUT
consuming the entry, so a frame stays visibly parked rather than
resuming inside a trapped module.
E-16 the E-5 handler read the realm-global scheduler at dispatch instead of
its installing module's; also frees the per-line buffer on the non-trap
rethrow path.
E-11 get_vec trusted the worker's res.length over the transferred arrays.
Observed death shape: a 4 GiB std::vector threw an unhandled
std::length_error that exited the editor's main loop. Now clamped, with
the buffers freed on every failure path.
Guardrails (replacing two deferred refactors: e2e→production-code injection and
collapsing the four copies of the worker-lifecycle machinery)
E-18 the source contract asserted comment-string counts — rewording failed
CI while moving a guard outside its #ifdef passed. It now parses the
#ifdef regions and asserts on code.
service-stub-parity.ts pins what the four lifecycle copies must share:
credit-window equality parsed from source, the finally-ack, boot
deadlines, terminal-notice consumption. The transport numbers are now
single-sourced from the worker.
CI actually runs the gates: the web/standalone vitest suites (which had
NEVER run in CI), the reducer, the source contract and the parity tool —
with a NON_PLAYWRIGHT_GATES check so deleting a step re-fails the lint.
E-22 the e2e occ stub's 60s boot watchdog, deleted in a66e109, is restored in
the ngspice-stub shape with a wedgeNextBoot() repro hook.
Every behavioral fix has red-then-green evidence (the reds were captured first).
E-17 (a stale RUNNING cross-stamping the next run's generation under E-6's
transport deferral) is DEFERRED with its analysis recorded — a real fix needs
run identity on the bg frames.
Test hygiene: the dwell lint now requires the mandated ": <why>" and all 47 bare
markers carry their reason; three export-report dwells became modal-lease polls;
exact-ledger assertions became relative deltas; the dead data-wx-dom-id branch,
an unused fault hook and unused receipt plumbing are gone; abort scans, wx
dialog drivers, the sim harness and the vitest FakeWorker are each one copy now.
Bumps kicad and wxwidgets to their findings-group-e tips.

Squash of experiment/ff-big-modules vs main.
Big-module routing removed: native-EH shrank kicad_editor below
SpiderMonkey's x86-64 code budget (runs 29355049705/29356152413 green on
stock Firefox), so BIG_MODULE_SPECS routing and the baseline-only-JIT
crutch are gone — kicad-firefox and kicad-chromium both run the full
suite, with the module compiled the way real users' browsers compile it.
Per-engine screenshots end to end: stableShot/shotPath write
test-results/<engine>/<name>.png; baselines move to
baseline-screenshots/{chromium,firefox}/ and the whole tools/screenshots
pipeline (compare/promote/manifest/spec-map/changelog/Discord) keys on
<engine>/<name>. Previously Firefox and Chromium renders of one spec
overwrote each other and Firefox renders were never actually gated.
Seeded from CI run 29421380806 (92 new firefox baselines, +24 chromium
web-suite shots); manifest generated from the baseline tree.
One merged playwright.config.ts (kicad/asyncify/coroutine/perf as
projects); ~25 dead npm scripts dropped. The web suite is gated in CI for
the first time ever (4 rotted specs fixed, 5 broken lib-bridge specs
triaged as fixme in docs/features/web-e2e-rot/); cheap lint step after
npm ci; last 26 blind-sleep violations fixed.
SwiftShader retired: CI Chromium renders WebGL on ANGLE → Mesa llvmpipe
(--use-gl=angle --use-angle=gl --ignore-gpu-blocklist; the blocklist flag
is mandatory — llvmpipe is blocklisted and WebGL is silently unavailable
without it) in BOTH configs. Under WORKERS=4 congestion SwiftShader
transiently failed the first post-board-load draw and the recovery
cascade ended in a silent permanent Cairo fallback — that engine flip was
the "~1.2% changedRatio both directions" occ-export baseline flake.
Validated 160/160 across two 80-repeat rigs; full analysis in
docs/features/wx-parity-bugs/occ-export-context-eviction.md. Chromium
baselines shift slightly on llvmpipe — promote once from the first green
run. Deflakes the new coverage exposed: presence baselines settle before
capture; presence fixtures declare current file formats; perf gets its
own outputDir so CI evidence survives; occ-export settles the board paint
before the export dialog; menu-item waits (waitForRenderedByLabel before
clickMenuItem) in 4 specs + the TESTING.md rule.
Web suite runs the PROD build, in parallel: webServer becomes backend
`start` + the standalone's e2e:preview (build-preview.mjs: link-wasm →
stash the public/wasm symlink aside during vite build, build-demo.mjs's
move — then vite preview as the persistent server). The wasm middleware
serves /wasm/* in preview and emits COOP/COEP/CORP itself (a pthread
worker script's own response must carry COEP or Chrome kills it with
ERR_BLOCKED_BY_RESPONSE). VITE_* flags bake at build time;
VITE_ALLOW_USER_OVERRIDE joins turbo globalEnv. fullyParallel + default
workers: 5.2m → 1.4m. Determinism fixes the parallel run exposed:
shared-page specs become serial groups; locks.spec grabs alice's exact
item via the new kicadCollabTestSelectByUuid hook (cross-tab "first
footprint" order is not a ysync invariant); quit specs poll page.url()
(quit supersedes its own navigation — NS_BINDING_ABORTED on Firefox).
Suite: 51 passed / 12 skipped / 0 failed in 1.6m.
CI-coverage gate (lint:ci-coverage): every tests/**/*.spec.ts must be
reachable from the npm scripts the workflows invoke — scraped from
.github/workflows/, resolved through package.json, coverage asked from
playwright --list itself. Rules: uncovered-spec + orphan-project (with a
documented LOCAL_ONLY_PROJECTS allowlist). Gating next to
lint:determinism; 138 spec files / 13 projects accounted for.
Product fixes kept from the investigations (reachable on real GPUs too):
wx 7799fd1be5 — paint flags clear before dispatch + Invalidate always
propagates; kicad 3dcfea5e45 — SwiftShader pass-boundary flush +
per-instance font texture + first-frame GL-error drain (GAL recovery
recovers instead of falling back to Cairo) + the user-facing eeschema
switch navigates again under __EMSCRIPTEN__ (project-sync's
FaceRegistered gate had rerouted it into the hidden sync player; caught
by the newly-gated web suite).

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.

backend-example (open ref backend): USER_HEADER, scope on the project DTO, raw routes under /api/scopes/:scope, no-op reportDrift + DOM lib (was red on main → now typecheck-green). GPL web specs (tools-open, symbol/footprint-write-remote, global-setup-web): /p/demo/:tool/* → /:scope/projects/demo/(file | -/:tool), direct API fetches scoped + x-pcbjam-owner → x-pcbjam-user. Reference backend keeps lib type 'user' (cosmetic vs closed 'org').
