The editor reported nothing when a session died. Evidence lived only in-tab —
an 800-line React array behind a "Show console" button — so diagnosis meant
asking a user to paste a screenshot.
Better Stack's Error Tracking ingests the Sentry wire protocol, so this runs
the stock @sentry/browser against a Better Stack DSN. Sentry.init installs its
own window error/unhandledrejection handlers, so uncaught main-thread errors
and the wasm traps that escape emscripten's DOM event handlers are captured
with no instrumentation at the throw sites. Not their JS tag: it has no
beforeSend or fingerprint hooks, its runtime spawns workers from cross-origin
CDN hosts (this page is COEP: require-corp), and it ships session replay on by
default — which on a CAD canvas records customers' board geometry.
@sentry/browser is imported in exactly one file so the vendor stays swappable,
mirroring how lib/analytics.ts isolates Plausible.
Also replaces the terminal-signature regex with a shared, unit-tested predicate
(wasm/terminal-error.ts) used by BOTH the fatal overlay and the reporter, so
they cannot disagree. The regex was a type check written as a string match and
had three live holes: `RuntimeError` was listed but never appears IN
`.message`; Chrome's bare "unreachable" and "null function" matched nothing
(the v0.1.20 prod log is exactly those); and narrowing "table index is out of
bounds" to `\bindex out of bounds` for Firefox in 197f317 silently stopped
matching Chrome's spelling. Checking the TYPE — every trap in this family is a
WebAssembly.RuntimeError — covers all engines and ends the spelling chase; the
message patterns remain as a fallback for paths that lose the Error object,
such as a worker ErrorEvent crossing the realm boundary with error: null.
197f317's pthread-worker tap, promote() and Firefox findings are kept as-is.
Notes:
- Off unless VITE_ERRORS_DSN is set AND VITE_ALLOW_USER_OVERRIDE !== "1" (dev
servers and every Playwright harness set the latter, and production builds
never do), so a production DSN in a local .env still cannot report. With no
DSN the whole SDK is const-folded out: 1,193,080 vs 1,282,463 bytes of JS.
- browserApiErrors integration removed. It wraps setTimeout/rAF/addEventListener
in try/catch, which is exactly how KiCad-on-Emscripten drives its main loop.
- Console breadcrumbs off (collab/debug.ts's clog fires per Yjs update and would
evict the ring before any crash); dom/fetch/navigation breadcrumbs kept.
- beforeSend redacts token/apiKey/Bearer — collab/provider.ts puts the collab
token in the y-partyserver URL, so a connection-failure string carries a live
credential — and guards the cascade: one wedge produced 8 errors in prod, and
after the first terminal event the rest are dropped into cascade_count.
Verified end to end against the real EU host from a cross-origin-isolated page:
POST /api/<id>/envelope/ -> 200, and 4 terminal throws produce 1 event
(control: 1 throw, same count).
Privacy policy 9, cookie policy 6 and the licenses page are updated: Better
Stack is disclosed as an EU processor, and the licenses page now describes the
browser app's own JS dependencies, which it never did.

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).

presenceUser()/userSlug() now resolve the authenticated user: a plain
/api/me fetch (GPL no-link rule — no closed contract import) races the WASM
boot and is awaited before presence/comments bind. `?user=`/`?libowner=`
overrides are gated behind VITE_ALLOW_USER_OVERRIDE=1 (dev script + e2e
harnesses set it; prod builds never do). Anonymous/example-backend sessions
keep the pre-auth slug fallback. Fixes prod's empty presence (everyone was
"local-user", deduped as own tabs) and comment authorship in one move.

- provider.ts: expose awareness on YjsProvider (partykit/hocuspocus surface
their own; BroadcastChannel gets a sibling-channel relay via awareness-bc.ts)
- presence.ts: createPresence — publish local PresenceState, subscribable
deduped peers() roster, setCursor/setSelection for P2, pagehide fast removal
- PresenceRoster.tsx + WasmTool wiring: facepile chip next to SourceChip;
eeschema rebinds per active sheet (sheet-manager ActiveSheet now carries the
room's provider); config presenceUser() = slug + colorForUser
- new dep y-protocols; unit tests (presence.test.ts) + e2e
tests/web/presence-roster.spec.ts (two tabs, verified vs real partykit)
- bump pcbjam-shared: presence-wire schema (MIT)

scripts/deploy/dev-demo.mjs (+ `pnpm dev:demo`) is the dev sibling of
build-demo.mjs: it runs the standalone via `vite dev` in the no-backend demo
configuration so a local WASM build can be exercised against the live R2 CDN.
- libraries: live R2 CDN (VITE_LIBS_SOURCE=cdn, libs/kicad/<lib-tag>, default
10.0.3) — IDB-cached, read-only; the lazy/fat lib-load path
- projects: the read-only example gallery (deploy/demo/gallery.json → the same
"Demo Board") built locally via publish-content.mjs and served same-origin at
/content/<gallery-tag>/; --content-tag pins the live CDN gallery instead;
--no-gallery falls back to local-folder + IDB only
- no partykit (VITE_YJS_PROVIDER=broadcastchannel), no REST backend
(offline.invalid → local-folder loader), browser-local IDB projects
- WASM: local fresh build at /wasm (default) or --wasm r2
The generated gallery (public/content symlink, web/standalone/.demo-cdn) is
gitignored, mirroring the public/wasm dev symlink.

Add the shared, uuid-keyed structural s-expr comparator (README §B) used by both
the live drift check (0003) and the round-trip tests (0004), plus a vitest setup.
- wasm/collab/sexpr-diff.ts: zero-dependency module (importable from standalone
app code and the Playwright specs). Tokenizes s-expr text into nested lists,
indexes item nodes by their direct (uuid "X") child, compares item sets order-
insensitively as multisets of normalized children, emitting
{ equal, added, removed, changed } with per-property a/b. ignoreTokens drops
volatile tokens. False-positive-free only for same-serializer inputs.
- wasm/collab/sexpr-diff.test.ts: 15 cases (parse, equality, changes, ignoreTokens).
- vitest config + test scripts (node env, isolated from the app build).

Generalize the collab transport into a provider registry (none |
broadcastchannel | partykit | hocuspocus), one active per env. startCollab
takes { provider, room } and awaits provider.whenSynced() before seed/adopt.
Network libs lazily imported; room id from @pcbjam/shared collabRoomId.

Reduce web/ to a single generic editor app plus a minimal example backend,
moving all project-specific/app code out to the closed root repo:
- apps/frontend -> standalone (@pcbjam/standalone): the GPL editor. Strips the
project-management UI (ProjectsPage/ProjectDetailPage/UploadDropzone and the
write half of lib/api.ts). WasmTool now takes fetchBytes + assetBaseUrl as
injected props (decoupled from the API client) so it can be driven by either
a backend or a local folder. New HomePage (local-folder loader + backend
project list) and read-only ProjectView. BroadcastChannel collab unchanged.
- backend (@pcbjam/backend-example): thin Fastify+ts-rest reference impl of the
@pcbjam/shared contract — serves a single project off the local filesystem
(PROJECT_DIR), no DB/auth/uploads.
- packages/contract -> web/pcbjam-shared (git submodule, MIT @pcbjam/shared).
- Remove apps/server, packages/storage, packages/contract, docker-compose
(server + storage move to the closed root repo; preserved via subtree
branches). Rewrite pnpm-workspace/turbo/.env for the frontend-only layout.
- Add tests/fixtures/demo so the editor + example backend run out of the box.
Standalone typechecks + builds; backend serves the contract end-to-end.
