extract-libs.ts gains extractAllLibs(): enumerate EVERY <Lib>.kicad_symdir / <Lib>.pretty under the source dirs into in-memory self-contained bodies (reuses the curated path's parse + extends resolution). At KiCad 10.0.x symbols already ship the one-symbol-per-file .kicad_symdir layout, so no split needed.
publish-libs.ts (tsx): per lib, build a SyncManifest (sha256 per item) + encodeBundle, write libs/kicad/<libTag>/<lib>/{manifest,bundle} (immutable) + a top manifest.json listing every lib. Keyed by upstream KiCad lib tag, skip-if-exists (HEAD the top manifest; --force overrides) so it is decoupled from the app deploy. Local + r2 drivers via cdn-store.
Validated over web/backend/.cache: 8 libs / 2154 items; Device bundle decodes to 537 bodies, its /manifest matches the bundle, and symbol/R body hash matches its manifest entry (warm-sync diff stays empty). Same wire format cdn-source.test reads, so publish and client are pinned to one format.

Backendless, read-only LibsSource that serves the full default symbol+footprint set from versioned immutable CDN snapshots. Each lib is an r2-idb-sync static origin opened as a one-layer SyncStack (1 bundle cold, 0 fetches warm, IDB-cached, offline) — the layer descriptor is built locally from lib id + tag, no resolve endpoint in the loop.
Wired via VITE_LIBS_SOURCE=cdn + VITE_LIBS_MANIFEST_URL; build-demo gains --lib-tag (points the demo at libs/kicad/<tag>/manifest.json; omitted keeps offline static). Unit-tested against a fake CDN built with the real encodeBundle/sha256Hex codecs, pinning the publish format.
Next: publish-libs.mjs (C1.2) emits this format over the full set; CI keyed by lib tag (C1.3).

Mirrors the closed app: create a templated file then open it, so you always edit a real file that saves back.
- lib/new-file.ts: minimal valid KiCad templates (pcbnew/eeschema/pl_editor, from the e2e fixtures) + document-tool helpers.
- NewFileDialog: in-project mode (file name) and home mode (pick/create a browser-local project + file name); writes via the active source uploadFileBytes (local IDB or remote-rw backend), then opens by path.
- HomePage: a document tool from the grid (local store on) opens the dialog instead of booting a throwaway blank doc.
- ProjectView: project-centric New-file row (writable projects) + Save-a-copy-to-browser fork for read-only gallery projects (copies into editable IDB), alongside files/export.
Also replaces a stray NUL byte that had been written into idb-project-store.ts in place of a space (made the file parse as binary) with an explicit unicode escape for the key separator (NUL, sorts below every slug char so project key ranges cannot collide) and the range upper bound. Runtime behavior unchanged.

Home page feedback: merge "Your projects" (local) and the gallery/backend list
into one "Projects" section where each ROW carries its own source chip (instead
of a per-section header chip). Sections are now Open → Projects → Tools →
Libraries. Local rows keep open/export/rename/delete; remote rows just open.
LocalProjectsSection → ProjectsSection.
Source chips were too pale on the editor canvas — switch from translucent pastel
to solid fills with white text + an inset ring, so they read on any backdrop
(home, dark boot screen, light editor canvas).

Loading a folder now imports a COPY into a browser-local IndexedDB project with
its own /p/:slug URL (original disk files untouched): edits persist to IDB across
visits, and the project exports via Download .zip or per-file. Gated by
VITE_LOCAL_PROJECTS=idb (on for the demo; off keeps the File System Access
write-back flow), so it's configurable per deployment.
Modular, swappable project sources behind the shared ProjectSource interface,
each self-describing via a SourceDescriptor whose kind is shown verbatim in the
UI — "Local (this browser)", "Remote · read-only", "Remote · editable" — on the
home page, the project view, and inside the editor, so the user always knows
whether/how Save persists:
- remote → REST backend (remote-rw)
- static → CDN gallery (remote-ro), saves download
- local (new) → idbProjectStore, writable IDB store
A composite layers the local store over the configured remote/gallery source,
routing per slug so imported/saved projects and the gallery share one namespace.
New, dependency-free (matching sync-client's raw-IDB ethos):
- lib/idb-project-store.ts raw IndexedDB store + create/delete/rename/export
- lib/zip.ts store-only ZIP writer (verified via system unzip)
- lib/import-folder.ts FSA/webkitdirectory folder → in-memory bytes
- lib/project-source-shared.ts source descriptors + deterministic uuid
- components/SourceChip, components/LocalProjectsSection
Home lists local projects (open/export/rename/delete). Verified: typecheck,
project-source tests, prod build, and IDB key-range project isolation in-browser
(prefix-colliding slugs don't leak).

A small fixed bottom-right overlay (VersionBadge) shown app-wide — on the home
page AND inside the loaded editor — surfacing this build's release tag and a
link to the source. The tag links to the exact commit when known (the pcbjam
commit pins the kicad + wxwidgets submodule revisions → our GPLv3
corresponding-source pointer, mirroring site Footer's BUILD_SHA), else the tag's
release page, else the repo root.
build-demo.mjs injects VITE_APP_TAG / VITE_GIT_SHA / VITE_REPO_URL (new --repo
flag, defaults to github.com/emergence-engineering/pcbjam).

- drift-detect.ts: every-N-edits + beforeunload check via kicadSave* (no save-hook), reports drift
- WasmTool: start drift detection after collab; return collab handle; stop on cleanup
- fix uuid-less docs (pl_editor): use ydocHasState in maybeConnectDocSession + seed() so a 2nd tab materializes the room instead of refetching the stale file

The WASM tools boot + fetch lib items with no visible feedback, so a big tool
download looks like a freeze and a failed body fetch (e.g. a backend 404) looks
like nothing happened. Add a full-screen boot overlay that stays until the wx UI
has actually built (waitForWxUi, gated on wxElementRegistry — not just boot
resolve, which flashes a blank editor), a debounced spinner while an item is
being opened/saved, and an auto-dismissing error toast when a body can't be
loaded. Driven by events the libs bridge now dispatches (LIB_BUSY/LIB_ERROR).

Add a deep-linkable, reload-safe route /l/<libId>/<tool> (LibToolPage) that boots
the editor scoped to one backend library; the home page's lib chips become
anchors to it (full nav → clean Emscripten). Local lib FILES stay in-place
(bytes can't be URL-addressed).
Fix empty lib trees against a registry server: fileless/lib-scoped launches use
the placeholder projectId "local", which was sent as x-pcbjam-project — the
closed server then scoped its (0005 mirror) lib resolution to a non-existent
project and returned nothing. Suppress the project header for "local"; real
backend projects keep sending their uuid and keep project-scoped resolution.

Open a single library scoped to itself in its editor: a backend lib (HomePage
chip → scopedLibsSource) or a local .kicad_sym/.kicad_mod file (LocalProjectView
→ localFileLibsSource + a browser-side multi-symbol .kicad_sym parser). WasmTool
gains an optional libsSource override (transparent default). All via the existing
lib bridge — no MEMFS doc open, no fork changes.
Also fix a systemic editor boot failure: the build split the wx glue into
wx.js + wx-dom.js, but boot.ts only injected wx.js + <tool>.js. wx-dom.js defines
window.wxDomCreateControl (used by every tool to build its UI), so without it the
canvas rendered but no wx controls did (ReferenceError: wxDomCreateControl is not
defined). Inject wx-dom.js between wx.js and the tool, best-effort (older non-DOM
builds tolerated). Bump pcbjam-shared for LIB_EXTENSION_TOOL.

Rework HomePage into KiCad-launcher-style zones: local file-load, a Tools grid,
backend projects, and a backend libraries listing (useLibs over the shared
listLibs). The Tools grid shows all seven tools in KiCad's standalone order
(Schematic/Symbol/PCB/Footprint editors, Gerber Viewer, Calculator, Drawing
Sheet); clicking a tool or a library launches the editor with no project
(launchedTool → WasmTool slug=local) — file-less editors browse backend libs,
document editors open blank. Harden the web e2e global-setup to assert the
self-provisioned origin libs (Device, Resistor_SMD) are present, failing fast.

Port the KiCad symbol/footprint brace-scanner parsers + a combined extractor
into web/backend/src/extract/; ensure-example-libs blobless/sparse-clones a
curated KiCad 10.0.3 slice and extracts to a gitignored .libs/ on dev/start, so
a bare GPL clone has libraries with no closed repo present. libsConfig() defaults
LIBS_DIR to ./.libs. vite honors STANDALONE_PORT (strictPort) so a second editor
can run on :3049 alongside the closed stack.

- 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.

Add kicadCollabSnapshotItems / kicadCollabApplyItems / window.kicadCollab.onItems
to pl_editor, eeschema, pcbnew — per-item native-blob payloads
({added/changed:[{sexpr,parent}], removed:[uuid]}) alongside the untouched scalar
wire (legacy collab specs stay green).
- pl_editor: itemBlob per item; apply = SetPageLayout(append) + replace-by-uuid
(pointer-snapshot safe); bare payloads get the kicad_wks envelope. Snapshot +
apply + emit verified headless.
- eeschema: clipboard Format per item (symbols carry their lib_symbols); apply
mirrors the native paste — LoadContent into a throwaway sheet → detach →
replace-by-uuid → symbol lib relink (blob's lib_symbols first, live screen's
second) → SCH_COMMIT, in the CallAfter+COROUTINE context. Snapshot + apply
verified headless (a "lost" lone junction turned out to be correct connection
cleanup — test uses text).
- pcbnew: blobForItem per ROOT item with child→footprint lifting in flushDiff;
apply = makeFromBlob + commit replace-by-uuid on the fiber; bare non-footprint
payloads get wrapInBoardEnvelope (live board layer table). Snapshot + footprint
replace/add WITH children (the 0004 containment gap, closed) + removal verified
headless. Track/via/zone/text blob-apply hits the documented asyncify-fragile
envelope parse (reconfirmed empirically — a verbatim SaveSelection segment
envelope dies silently in the commit) and stays on the legacy scalar apply;
tracked in ysync 0008 status.
- eeschema/pcbnew scheduleFlush now runs flushDiff inside a COROUTINE: the
per-item Format in the v2 emit needs the fiber stack (0007 lesson). Their emit
remains unverifiable headless (both legacy two-tab tests are test.skip:
"open=false → SCH_COMMIT no-ops" / "harness can't PAINT") — verify in the real
app at Stage D; pl_editor's emit IS verified.
- tests/kicad/items-bridge.spec.ts: per-tool suite (snapshot uuids → local-edit
emit (where drivable) → apply changed/added/removed via save-readback → no
apply echo). 3/3 pass; roundtrip + collab suites unaffected.

- 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.

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).

The automatic recovery uses an in-place location.replace reload, which does NOT
reliably release the OOM'd wasm heap in every browser (notably Firefox), so the
respawn can land right back in an out-of-memory state.
Add a user-gesture escape hatch to the terminal MemoryExhaustedDialog: an "Open
in a new tab" button that opens the editor in a fresh top-level browsing context
(clean retry chain) and closes the current tab. Because it runs from a real
click, window.open is not popup-blocked; window.close() may still be refused on
the original user-opened tab, which is fine — the new tab is the survivor. Copy
tells the user this sometimes helps where the in-place reload didn't.
- oom-watch.ts: export respawnInNewTab(win) — fresh-tab respawn with ?oomRetry
cleared.
- MemoryExhaustedDialog: "Open in a new tab" (primary) + "Reload this tab"
(secondary), with honest copy about Firefox + unsaved edits.
- WasmTool: wire onOpenNewTab to respawnInNewTab.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Automatically recover from an out-of-memory by respawning a fresh browsing
context (fresh wasm heap) and discarding the dead one — the manual "duplicate
tab, close the OOM'd one" fix, automated and capped at 2 retries so a too-small
machine stops instead of looping.
- recovery/oom-watch.ts: the recover() state machine with the retry counter in
the URL (?oomRetry=N, cap 2). Mode A soft detection — Module.onAbort plus
window error/unhandledrejection matched against an OOM signature, behind an
idempotent latch. Mode B hard-kill detection — a per-tab localStorage
heartbeat sentinel; a stale sentinel on the next load continues the retry
chain (heartbeat keys avoid mistaking a second live tab for a crash). Healthy
session (alive HEALTHY_RESET_MS) resets the chain. Default strategy is
location.replace; window.open+close is behind ?oomStrategy=newtab. Platform
access goes through injectable win/storage seams for testability.
- recovery/MemoryExhaustedDialog.tsx: terminal "out of memory" UI, reusing
0001's BlockingDialog; copy is honest about lost unsaved edits.
- wasm/boot.ts: forward emscripten Module.onAbort to the watcher (optional
BootOptions.onAbort).
- WasmTool: install the watcher, gate boot on its proceed flag (skip when the
chain is already exhausted), and render the terminal dialog.

Add a pre-boot "potato check" for the standalone editor: probe the device
against what the KiCad WASM tools actually require and warn (or block, with an
override) before the expensive WASM asset fetch.
- preflight/capabilities.ts: pure, unit-testable probe → CapabilityReport with
stable codes. Fatal: no SharedArrayBuffer/cross-origin-isolation, no
WebAssembly, no Workers+Atomics, no WebGL2. Warn: low deviceMemory, low JS
heap limit (Chromium), few cores, mobile, small screen. Thresholds in one
tunable const block.
- preflight/BlockingDialog.tsx: reusable modal blocking overlay (no dismiss
except via explicit action) — also for feature 0002's terminal dialog.
- preflight/PreflightGate.tsx: runs the probe once on mount; fatal → blocking
dialog with "Try anyway" (short-circuits the asset fetch); warnings →
dismissible advisory banner with localStorage "don't show again" keyed to the
exact warning codes.
- ToolPage: wrap WasmTool in PreflightGate so the gate runs before boot.
Optional micro-bench (phase 3) deferred per the spec.

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.

pcbnew's half of the unified Yjs collab bridge (4th tool; yjs-bridge commit 4),
a near-verbatim port of the eeschema design. Root-repo only — kicad/wxwidgets
submodules untouched.
- wasm/bindings/pcbnew_embind.cpp: BOARD_LISTENER trigger + post-settle snapshot
diff emit; BOARD_COMMIT apply inside a CallAfter + COROUTINE fiber (so a new
item's GAL view->Add dispatches correctly). Move/delete sync for any top-level
item by uuid; native PCB_TRACK add. Footprint/via/zone add deferred.
- WasmTool.tsx: add pcbnew to COLLAB_TOOLS.
- tests/apps/kicad/pcbnew-collab.html: seeded (wizard-free) harness, leaving
pcbnew.html untouched for its wizard test.
- tests/kicad/pcbnew-collab.spec.ts: snapshot + apply(move/remove/add) — 2 pass,
two-tab skipped headless.
Verified two-tab in the real web app: footprint move applies + syncs A->B.

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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.
