- P-5: blobForItem returns "" for PCB_FIELD_T (the file writer cannot format a
field standalone → hollow (kicad_pcb …) envelope); liftBlob skips empty blobs
and STRUCT_DELETED roots with a console breadcrumb; the scalar added path and
the seed never attach an empty blob.
- P-1 (not reproduced, structural): the runOnCoroutine apply body runs in
try/catch(...) so an unwinding body still marks the slot done instead of
wedging fit/pan/flushDiff/remote applies forever; new probe
kicadCollabTestApplyQueueState() → {busy, queued}.
- P-4: wxwidgets 9666a743bc (TLW SetFocus delegates to a child,
menubar never takes focus); probe kicadTestFocusWindow() (wx FindFocus).
- Specs: tests/kicad/findings-p.spec.ts (P-1 ×3, P-2 probes as fixme, P-3 ×2,
P-4, P-5), tests/web/findings-p1.spec.ts (P-1 on the real standalone).
P-2 verdict: stock KiCad candidate priority, text scales normally; P-3 not
reproducible — see docs/features/findings/groups/P-editor-tools-embind-interaction.md.

section so the merged kicad_editor image carries it): runOnCoroutine →
ACTIONS::show3DViewer.
- Session menu: "3D viewer" row (pcbnew) — the only 3D entry once the wx
chrome is hidden. Runs the deferred model prescan first.
- Read-only sessions: skip the boot-time enableRealtime scope-room socket
(would 401 for non-members) and defer the board's 3D-model prescan until
the viewer is opened (deferBoardModelPrescan / runDeferredModelPrescan).
- kicad submodule → read-only allowlist for the 3D viewer actions.

Canvas-only sessions (read-only viewers, hide-UI editors) get two
floating, draggable, closable panels standing in for the chrome-hidden
wx panes, opened from the overlay menu's View section:
- wasm/bindings: layer bridge — kicadLayersGetState/SetVisible/SetActive
(bodies mirror the compiled-in-but-unreachable IPC handlers, applies
on the coroutine lane, fresh state pushed to
window.kicadCollab.onLayersState); setters join the jspi-scheduler
mutator lane.
- standalone: LayerPanel + SelectionInspector on the comments-panel
shell conventions (useDraggablePanel, collapse, persisted state);
local-selection store fed from presence's onSelection in edit
sessions and bindLocalSelectionFeed for read-only viewers (with a
bounded post-gesture pull burst — clarify-menu selections produce no
canvas event); pure item-summary extraction + unit tests.
- kicad submodule: read-only selection unlock (selection live for
inspection; point editors + RMB context menus stay locked).
- tests/web: read-only spec updated — viewer click selects (or pops the
clarify list), RMB context menu suppressed with writer positive
control, Delete still swallowed; new viewer-panels test (eye toggle
round-trip, active layer, panel drag, inspector rows from a real
canvas click).
Record: docs/features/read-only-viewer/0002-viewer-panels.md (root).

- itemToJson: pass PADSTACK::ALL_LAYERS for vias — the layerless virtual
PCB_VIA::GetWidth() is an assert trap since the padstack refactor, and the
collab baseline/snapshot serializer hit it once per via per snapshot
(big-board load = assert storm). Values were already correct; wire format
unchanged (applyChanged's layerless SetWidth writes the same slot).
- console: closed state is a content-width bottom-left tab again (version
badge + app bottom edge visible); opened footer panel unchanged.
- console: partial-selection copy works — wx's window-level keydown handler
preventDefaults Ctrl/Cmd+C, so a capture-phase guard stops propagation to wx
when the selection lives in the console; canvas mousedown collapses stale
log selections so they can't steal the editor's own Ctrl+C.

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 BUG IS FIXED. tests/kicad/quasimodal-strand.spec.ts flips from a
test.fail() pin to a plain green regression test: 3/3 runs
closed=true dialogs=0 refused-resumes=0 (was closed=false dialogs=1
refused-resumes=1 on every run).
Mechanism: a quasi-modal's nested event loop parked on the TOOL
COROUTINE's stack, which suspends the fiber's body where the fiber layer
cannot see it — so the stale-fiber guard quarantined the fiber and then
refused its own resume, the dispatch guard was never released, and every
click after that was deferred forever. Bouncing the nested loop onto the
main stack leaves the coroutine suspended the legitimate way (a recorded
fiber swap), so nothing is quarantined and nothing is refused.
Layering, so this is not a pile of WASM ifdefs in KiCad:
- wx (3d37db3bf1) owns the POLICY and the hook; it must not know what a
coroutine is.
- wasm/bindings/main_stack_runner.h is the only place that may know both
sides: it finds the frame's TOOL_MANAGER and bounces via RunMainStack.
Header-only and self-installing, so no build-script change; included by
every editor's binding TU.
- KiCad gets ONE ifdef-free method (2c777efede), needed only because
TOOL_STATE is opaque outside TOOL_MANAGER. libcontext and dialog_shim
are untouched — an earlier draft edited both and was reverted.
This also reframes the remaining plan: the doc-19 class is closed WITHOUT
migrating tool coroutines onto scheduler contexts. Note it does not make
the wait a context yield — waits still park in place, just never on a
coroutine stack.

kicadTestFiberParkStartSecond/PokeSecond: a second coroutine started while
the first body is asyncify-parked reproduces the misattributed jump that
launders the parked fiber past the C++ guard (the v0.1.21 prod bypass).
Spec scenario 2 stages it and asserts the JS stale-rewind guard quarantines
the laundered resume (exactly one fiber-resume-refused beacon), the parked
body completes undisturbed, and both coroutines finish cleanly.

Companion to kicad f0ce20ef64 (libcontext swap_suspended guard), which this
pins. The v0.1.20 diagnostics decoded the crash that survived v0.1.13–19:
TOOL_MANAGER Resume()s a coroutine whose body is asyncify-parked inside
handleSleep, the swap rewinds the stale fiber suspension, and the runtime is
poisoned. Full chain of evidence in docs/features/async/16-fiber-resume-guard.md
(+ round-3 addendum in 15-timer-park-repro.md).
- wasm/bindings/fiber_park.h + kicadTestFiberPark{Start,Prime,Poke,State}
exports (pcbnew + merged kicad_editor): stages Call→yield→legitimate
resume→sleep park→mid-park Resume, the exact prod state machine. The
first yield matters: it primes a real (then stale) suspension, matching
long-lived tool loops rather than a first-slice park.
- tests/kicad/fiber-resume-park.spec.ts: asserts the healthy contract on
polled state only (embind returns across fiber swaps are unwind
placeholders). RED on the unguarded build — fiber/sleep buffer
cross-restores, a jump-ghost beacon, the parked body zombified. GREEN with
the guard: mid-park poke refused ([collab-fcontext] jump-refused beacon),
park completes, post-yield resume works, no trap signatures.
- Regression sweep green: timer-park-repro, collab-load-fuzz, load-pcb,
pcbnew-collab, collab-undo, eeschema-collab (19 passed).

kicadTestArmTimerPark(delayMs, parkMs): a one-shot wxTimer whose Notify()
emscripten_sleep()s, entering through the exact GAL-refresh-timer path
(emscripten_async_call → TimerCallbackFunc::Run → dispatch guard → Notify) —
the fresh-entry-that-parks the prod board-load trap family needs. Pollable
kicadTestTimerParkState(); inert unless armed. Registered beside
kicadTestSetOpenPark in pcbnew + the merged kicad_editor image.
tests/kicad/timer-park-repro.spec.ts drives four escalating cycles (park
only, 2× + fiber hammering, + 256MB heap growth mid-park) and asserts the
runtime survives every rewind AND that the [wx-asyncify] diagnostics observed
the window — engagement is asserted, so a run where the lever never created
the overlap cannot pass vacuously.
Result so far (docs/features/async/15-timer-park-repro.md): GREEN through
both rounds — genuine double-parks, live currData cross-restores, fiber
swaps, and mid-park heap growth are all handled by the shim + runtime. The
prod trap needs an ingredient this window still lacks (ranked in the doc);
the spec stays as the regression gate for whatever the eventual fix is.

runOnFiber now runs bodies strictly one-at-a-time through a park-safe FIFO
(collab_common.h): the per-body fire-and-forget coroutine interleaved under
load — an asyncify park inside commit.Push let the event loop start the next
body, so a local commit and a remote apply ran interleaved on shared state
(s_applyingRemote is one global), silently losing applies on the actively-
editing receiver (fuzz finding #10a; B now fuzzes clean; 39-test suite green).
kicadCollabFiberBusy embind probe (merged + standalone registrations): a
bare-embind-stack scratch save during a parked fiber mis-dispatches (table
index OOB) — trio.ts modelText/drift and production drift-detect now defer
while fiber work is in flight (#10b hardening; the trap's root cause is still
open and needs a symbolized stack — fuzz stays fixme'd).

drift-trio-scenarios.spec.ts: disjoint ping-pong, same-item interleave (no
settle between bursts), conflict pairs (move-vs-delete / value-vs-value /
move-vs-move — winner is CRDT policy, asserted only as convergence + drift
silence), undo storm, 12-edit burst churn, late-joiner adopt, and Ctrl+S mid
peer burst; per-tool adapters, marker-waits before every sweep (finding #7).
S4 exposed finding #9: mutation hooks resolved item pointers at call time and
committed later on the fiber — a remote remove in between frees the pointer
(doApplyItems) and the commit resurrects the deleted item. Phase-B mutation
hooks now re-resolve by uuid ON the fiber; a vanished item makes the mutation
lose silently. applyDeltaToY's concurrent update/delete verified coherent
(full resurrect or full remove) — no shared change needed. trio.ts: TabSet
oracles + exported startV2 for duo/late-join composition.

17 kicadCollabTest* action primitives (eeschema: wire/junction/no-connect/
label/symbol/move/mirror/duplicate; pcbnew: track/via/text/zone/flip/
footprint-field/lock/move/duplicate), each a real SCH_/BOARD_COMMIT on the
fiber so the listener → flushDiff emit runs as for UI edits; tool-unique

eeschema adds SetParent before staging (Push silently skips listener
notifications for unparented items), and pcbnew blobForItem now Formats
non-footprints with the FILE writer + wrapInBoardEnvelope — SaveSelection's

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.

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).

synced-source subscribes to its SyncStack: remote changes (self-save echoes
consumed via a selfPushed flag) debounce per kind into kicadLibsReload — a
new embind export (pcbjam_libs_reload.h, all three TUs) that drops the lib's
plugin cache (LIBRARY_MANAGER::ReloadLibraryEntry), reloads it, and mails
MAIL_RELOAD_LIB with the nickname so the symbol tree force-refreshes (the
plugin's modify hash is a pinned constant, so a plain sync would skip it).
After the reload, kicadLibsSymbolUsage (new eeschema embind: placed
SCH_SYMBOL count across unique screens) gates LIB_ITEM_UPDATED_EVENT, and
WasmTool shows an amber toast when a PLACED symbol changed — placed copies
keep the previous version until updated from the library.
syncedScopeLibsSource gives PROJECT sessions the synced source under
VITE_LIBS_SOURCE=synced (remote contract for lib listing/createLib, lazy
per-lib SyncStacks for item ops/presync) so realtime reaches open
schematics; previously project sessions silently fell back to the per-item
remote source. Unit tests cover reload debounce, self-echo skip, per-kind
routing, usage-gated event, and the no-Module no-op.
Bumps kicad (MAIL_RELOAD_LIB force-refresh payload).

Follow-user: click a peer's roster avatar to mirror their viewport until
local input breaks it.
- collab_presence_core.h: CORE::fitViewport(cx, cy, halfW, halfH) — fit the
leader's world rect with CONTAIN semantics (zoom derived from the
follower's own canvas via the ToScreen ratio; GetScale is the zoom, not
px/IU). Exported as kicadCollabFitViewport from both editor TUs + the
merged dispatcher.
- presence-kicad.ts: publish the visible world rect (viewportRect) into
awareness, 100 ms trailing throttle; guarded for pre-0008 handles.
- follow-user.ts: createFollow — follows an awareness CLIENT (a tab, not a
user); applies leader rect changes via FitViewport, dedupes unchanged
republishes; break-on-interact compares local onViewport echoes against
the last applied rect (2% rel tolerance, echo-grace before the first fit
lands); unfollows on leader-left; pauses on eeschema sheet mismatch.
- PresenceRoster: avatars are follow toggles (ring on the followed peer);
WasmTool renders the "Following <name> — move to stop" banner.
- tests: 7 controller units (85/85 collab), fitViewport round-trip e2e in
both kicad presence specs (20/20), two-tab tests/web/follow.spec.ts
(converge → track → wheel-zoom breaks → subsequent moves ignored).
Chip depth-layer fix (user-reported): name chips washed out inside
low-alpha selection fills — chip rects shared the shapes overlay's single
depth, and same-depth fragments drawn LATER lose the depth test, so an
earlier-painted fill rejected the chip's pixels. Now three layers via the
fork's VIEW_OVERLAY::SetDepthOffset: text (0) < chips + pin dots (1) <
selection shapes (2). drawLabel/drawCursor/drawSelectionBox take the chip
overlay explicitly; comment-pin dots move to the chip layer too (the 0005
"drawn last so pins sit above" comment had the rule backwards). Verified
with a chip-inside-30%-fill pixel repro + the full presence suite.

The eeschema/pcbnew binding TUs had ~1000 lines of copy-pasted collab code.
Factored into two header-only shared files (zero build-script changes — the
collab_presence_style.h precedent):
- collab_common.h (pcbjam_collab): toUtf8, runOnFiber (the CallAfter+COROUTINE
fiber idiom — was ~25 inline copies), the window.kicadCollab wire emitters
(onDelta/onItems/onCursor/onSelection/onViewport), frame-generic undo test
hooks.
- collab_presence_core.h (pcbjam_presence::CORE): PEER/PIN + all presence
state and machinery (start/canvas binds/lock query, setRemote/setPins/
setStyle, selection check + dedupe, overlay redraw loop, viewport push/pull,
releaseSelection, locks probe), written against the EDA_DRAW_FRAME +
SELECTION_TOOL base classes. Per-editor hooks: frame, selectionTool,
selectionEmitPayload, resolveItem, drawPeerShapes. One CORE instance per TU
(anonymous-namespace presenceCore()) so the merged image keeps per-editor
state separation.
- NEW per-editor resolveXsel(frame, peer): ONE cross-app resolver shared by
the ghost render AND kicadCollabTestGetCrossMapped — the mapping loop was
duplicated within each TU, letting the test probe drift from the pixels.
Deliberately NOT factored: the Yjs differ/apply halves (itemToJson/makeItem/
flushDiff/doApply*) — structurally parallel but the bodies encode per-editor
sync semantics and editor-specific asyncify devirtualization workarounds that
must stay visible. kicadOpenFile/kicadCollabOnSave keep the existing
KICAD_MERGED_EMBIND mechanism. TestClearSelection stays editor-typed
(ClearSelection is not on the SELECTION_TOOL base).
eeschema_embind 2203→1721 lines, pcbnew_embind 2518→1993. JS-facing names,
signatures and the kicad_editor_embind.cpp dispatcher are unchanged.
Verified: kicad_editor image builds clean; tests/kicad presence+locks 18/18
(incl. ghost-render pixel compares), collab+ysync-repros 31 passed/2 skipped.

Ctrl+Z after a peer's edit no longer reverts (and re-broadcasts) the
peer's work, and the adopt undo-bomb is gone:
- doApply/doApplyItems (both editors) Push with SKIP_UNDO; the emit path
is unaffected (suppression keys off s_applyingRemote, not undo).
- With SKIP_UNDO no picker owns removed items — the bindings free them
after Push (explicit removals + upsert's remove-before-re-add; fields
excluded: CHT_REMOVE hides them, parent keeps ownership). Freeing stays
out of the fork commit classes so DRC's SKIP_UNDO callers can't
double-free.
- Test hooks kicadCollabTestUndo/UndoDepth, registered per-editor AND in
the kicad_editor dispatcher (merged image compiles out per-app
registrations).
- kicad pointer: eeschema UUID undo guard + SKIP_UNDO connectivity split
+ quiet stale-entry drop (ca8877324c).
- tests/kicad/collab-undo.spec.ts: 5 scenarios (no undo entry from remote
applies; selective undo; stranded replaced/deleted entries) — 5/5, plus
collab/ysync regression 30 pass.
- docs: ysync-review 20 fix record; 09 marked FIXED; overview indexed.

While a peer has an item selected, local users can still select it for
inspection but move/drag/rotate/delete skip it with an infobar naming the
holder (native locked-item UX; enforced via the fork's PCBJAM_REMOTE_LOCK
query — kicad 81f9cd80fd, the epic's first fork-touching phase). Overlapping
holds (both grabbed inside the awareness propagation window) tie-break
deterministically: lowest (user.id, clientID) keeps the item, every losing
client auto-releases it.
- lock-tiebreak.ts: pure policy — beats(), remoteLocks() (union of ALL other
clients' selections incl. own user's other tabs, minus own-held-and-winning
uuids so the winner isn't blocked mid-release), contestedReleases()
- presence.ts: clients() (per-client view, no user dedupe) + self(); FIX for
a pre-existing flaky stack overflow — resolveCollision re-entered itself
synchronously via its own patch's awareness 'change' and could ping-pong on
stale same-user states (~1-in-3 unit runs); re-entrancy guard defers
re-resolution to the next genuine delivery
- presence-kicad.ts: locks ride the kicadCollabSetRemote snapshot
(`locks:[{uuid,name}]`); losing overlaps call kicadCollabReleaseSelection
- wasm bindings (both TUs + merged dispatch): g_locks map + fork query
install; kicadCollabReleaseSelection (cancelInteractive only when a tool
stack is live — bare ESC would clear the whole selection — then selective
RemoveItemFromSel + infobar + forced re-emit); kicadCollabTestGetLocked
- tests: lock-tiebreak unit suite; presence-locks e2e for both editors (real
move veto — pcbnew click+M hotkey since its default left-drag is
rubber-band select, eeschema real drag — each with an unlocked control);
two-tab tests/web/locks.spec.ts (lock propagation + deterministic tiebreak
release + unlock on clear, passing vs real partykit)

Selecting a symbol in eeschema ghost-highlights the linked footprint(s) in
every pcbnew tab of the project, and vice versa — across users AND one
user's own two tabs. Native KIWAY cross-probe is inert in WASM (one frame
per page); this rides the presence layer instead.
- cross-app.ts: project-wide awareness-only room (presenceRoomId), publishes
full PresenceState at selection rate (cursor always null); peers() = other-
TOOL clients incl. own user's other tabs; window.__pcbjamCrossApp test handle
- presence-kicad.ts: parseSelectionEmit (bare array | {uuids,fpPaths}),
xselFromPeerState (pcbnew paths → symbol uuids; eeschema uuids verbatim),
cross peers appended to the kicadCollabSetRemote snapshot as
{id "<user>#x<client>", name "<user> · sch|pcb", xsel}
- C++ (zero fork changes): pcbnew emits {uuids, fpPaths} (FOOTPRINT::GetPath)
and ghost-renders xsel via path-tail suffix scan; eeschema resolves xsel via
ResolveItem gated to the CURRENT sheet (xsel arrives project-wide, unlike
room-scoped selections); ghostStyle = alphas × xselAlphaScale (0.55, tuner-
patchable); new exports kicadCollabGetSelectionFull / TestGetCrossMapped /
TestSelectComponent (skips power symbols — PWR_FLAG has no footprint) +
merged-image dispatch
- tests: presence suites extended (payload shape, ghost render pixel tests,
13/13) + new two-tab tests/web/cross-probe.spec.ts (passing vs real
partykit); eeschema pixel compares now target the #glcanvas-* GAL panel
(the whole-window #canvas compare flaked on the auto-dismissing version
infobar — also fixes the long-known presence-eeschema restore flake);

The full root-cause chain of the empty/mangled badges:
- GAL text justify is painter-residue → PRESENCE_TEXT_OVERLAY pins TOP-LEFT.
- VIEW_OVERLAY::ViewDraw hard-sets EVERY overlay to GetMinDepth(), so the
shapes and text overlays always collided at one depth, where later-drawn
fragments lose (and bitmap glyphs are textured quads whose transparent
cells also write depth — punch-through produced cell-shaped holes instead).
Fix rides the new fork VIEW_OVERLAY::SetDepthOffset: shapes at min+1,
labels at min — 'rect first, text on top' now holds regardless of paint
order. Verified: chips contain crisp names (dark-on-light, white-on-dark)
for selection tags and cursor labels; presence suites 10/10.
- kicad pointer bump (fork 24c5854d5b).

Two root causes of the wandering/invisible badge text:
- A plain VIEW_OVERLAY draws with whatever text justify the LAST painter left
in the GAL (CENTER is only the reset default) — anchoring was
nondeterministic. PRESENCE_OVERLAY (VIEW_OVERLAY subclass, replaces
MakeOverlay) pins TOP-LEFT justify before executing its commands; the label
math is written against that.
- The whole overlay draws at ONE depth and same-depth fragments drawn later
LOSE the depth test — a chip rect over its text erased the text. Draw the
text FIRST, the chip rect AFTER: the rect is rejected exactly on the glyph
pixels, punching the text through.
Verified live: chips contain their names on light (dark text) and dark
(white text) user colors, for both selection tags and cursor labels.

- collab_presence_style.h: GAL BitmapText CENTERS on its position (confirmed
in GAL::ResetTextAttributes — the mispositioned nameplates); labels/chips
now hand GAL the block center. New selection shape 5 'exact outline':
pcbnew hugs real geometry (footprint bounding hull, TransformShapeToPolygon
for the rest, padding inflates the polygon); eeschema falls back to rect.
- kicadCollabTestDemoSet (both TUs + merged): labeled demo groups — smallest
+ largest footprint and the two busiest nets' segments (symbols + wire
bundles on sch) — so the style preview covers the real range of shapes.
- PresenceTuner: Colors section rebuilt as explicit modes (per-user / fixed /
palette) with preset palettes (default, pastel, vivid, okabe-ito), buffered
hex editing + Apply (the old always-filtering textarea ate keystrokes), an
'overlay only' hint; demo injection consumes the varied demo set; 'exact
outline (pcb)' in the shape list.

Parametrizes every visual knob of the presence overlay so we can pick the
shipped look live, then wire the winners into the defaults:
- collab_presence_style.h: shared STYLE struct + drawing (now used by BOTH
editor TUs — no more duplicated overlay code): selection shape (rect /
corner brackets / underline / rounded rect / filled-only), border width +
alpha, infill alpha, padding, corner radius; name tag show/size/chip-
background/inside-outside/top-bottom/start-end-center/offset; cursor shape
(cross / pointer / circle+dot), size/width/alpha + label knobs; fixed-color
and palette-by-name-hash overrides (try palettes without changing what
senders publish); pin radius/ring/alphas. Defaults == shipped look.
- kicadCollabSetStyle(json) live-patch export + kicadCollabTestListItems(n)
(real KIIDs for synthetic previews); merged dispatch; pins now carry the
author name so palette overrides recolor them consistently.
- PresenceTuner.tsx: floating dev panel (env-gated, tree-shaken otherwise) —
grouped sliders/selects, demo peers+pins injection for SOLO tuning,
localStorage persistence across reloads, Copy JSON export, reset.

Hybrid pins: the wasm draws the dot (kicadCollabSetPins rides the presence
VIEW_OVERLAY, author color + white ring, drawn above selections; zero
kicad-fork changes), the DOM owns interaction —
- comments.ts: controller gluing the MIT kdoc_comments helpers to the editor:
anchor resolution per tool IU (pins track item moves via kdoc_items
observation), throttled pin snapshots, anchorAt nearest-item snap, jumpTo
via new kicadCollabSetViewport; rebinds per sheet like presence.
- CommentLayer.tsx: comment mode (click catcher + composer), pin hit targets
over the GAL dots, thread popover (reply/edit/delete own, resolve/reopen,
delete thread), panel with resolved filter + jump-to (popover centers when
the pin is off-screen). Resolved pins drop figma-style.
- WasmTool: controller lifecycle beside presence; live viewport feed;
window.__pcbjamComments test handle (threads persist in the room ydoc).
- e2e tests/web/comments.spec.ts: two-tab create → reply → resolve → panel
filter → delete, passing vs real partykit; presence suites + collab units

Zero kicad-fork changes — all in the embind layer:
- pcbnew_embind.cpp: presence section — canvas wx Bind() triggers (motion/
leave/up/key/wheel) + COLLAB_LISTENER piggyback → post-settle selection
check (dedupe) → onSelection; throttled cursor emit via VIEW::ToWorld;
viewport push/pull (px-per-IU via the GAL matrix — GetScale() is the zoom
and sized the first cut's overlay nm-small); kicadCollabSetRemote renders
peers' cursors (cross + name) and selection bbox outlines into one
per-user-colored VIEW_OVERLAY (CallAfter+COROUTINE), never touching local
selection; PresenceStart/GetSelection/TestSelectFirst/TestClearSelection.
- kicad_editor_embind.cpp: merged-image dispatch (pcb-only until 0003).
- presence-kicad.ts: bindKicadPresence — routes emits into awareness (0001)
and pushes trailing-throttled peer snapshots into the wasm; wired from
WasmTool.startPresence (pcbnew-gated). +5 unit tests.
- tests/kicad/presence-pcbnew.spec.ts: 5 e2e — programmatic + real box-select
emit, throttled cursor, remote render with no-leak + pixel restore,
viewport unit band. Existing pcbnew-collab/items-bridge suites stay green.

outline visible on the other tab's canvas.

All seven ysync-review bugs fixed and verified; every repro's expected-fail
marker removed (they now run as regression tests). Also fixes two bugs found
while verifying (doc 17 F5/F6): file-seeded Y bodies are re-upserted in the
editor's serialization (doc-16 F4 was an artifact of bug 01), and the
0008-era "asyncify-fragile envelope parse" was really wrapInBoardEnvelope
emitting display layer names — canonical LSET::Name() fixes track/via/zone
v2 applies; makeFromBlob now logs parse errors instead of swallowing them.
Verified: shared 98, standalone collab 37, ysync e2e 20/20 (chromium),
collab regression set 21 passed / 3 pre-existing skips (firefox).
Bumps: kicad (board_commit child-removal listener notification),
web/pcbjam-shared (slot prune + arbitrated seed).

The 2026-07-02 sync review (docs/features/ysync-review, ysync-review branch)
found 7 bugs and that the two-tab e2e only exercised the DEAD legacy scalar
wire. This lands plan doc 15 in full; results + empirical findings in doc 16.
- tests/collab/browser-entry-v2.ts (+build.mjs): the PRODUCTION v2 stack
bundled for e2e (connectKicadDoc + attachKicadCollab, kdoc_* keys), with
in-page renderActiveDoc/singleSeedRender/driftReport helpers and yjs forced
to ONE copy (the two web pnpm workspaces otherwise bundle two
instanceof-incompatible instances).
- tests/kicad/ysync-two-tab.spec.ts: pl_editor green baseline (A↔B edits,
ITEM-level drift silence) + divergent-uuid adopt; bug-01 pcb/ee fresh-room
repros (Chromium-only: two kicad_editor tabs exceed Firefox's per-process
wasm budget); bug-06 concurrent-seed race; bug-03 Y-half.
- tests/kicad/ysync-repros-{pcbnew,eeschema}.spec.ts: bugs 02/03/05 + the
bug-04 matrix (anchor-centred fp rotation, pad resize, endpoint drag,
symbol rotation, Value-field edit), each with green landed-preconditions;
the "local move emits" controls double as headless-emit probes — GREEN on
both tools, so every emit-dependent repro is a live test.fail.
- wasm/bindings: 7 local-edit test hooks via real commits
(CallAfter+COROUTINE) — TestRemoveItem/TestRotateItem (both tools,
dispatched in the merged image), TestSetPadSize/TestMoveEndpoint (pcbnew),
TestSetFieldText (eeschema).
- web/standalone ysync-repros.test.ts: bug-01 units (C++-faithful fake gating
emit on ensureBridge) + bug-07a/b (stale DOWN hook, real sheet-manager gap).
- web/pcbjam-shared bump: bug-03/06 unit repros.
Convention: every repro asserts the CORRECT behavior and is expected-fail
(test.fail/it.fails) naming its bug doc; a fix flips it to "unexpected pass",
forcing marker removal — the repro becomes the regression test. Every
expected failure verified (JSON reporter) to fail at its documented assert.
Suite state: 39 passed / 0 failed / 0 flaky / 5 skipped (2 firefox guards,
2 pre-existing legacy two-tab skips, 1 pre-existing roundtrip fixme).

All four editors (PCB / Footprint / Schematic / Symbol) are now runtime --frame
choices of a single kicad_editor.wasm (178 MB at -O1 vs 147+82 separate; shared
wx/common/boost linked once). One editor per page load, as before; frames pcb /
fpedit / sch / symedit.
- wasm/editor/: the merged executable target (single_top + both kiface library sets,
whole-archive pcbcommon) + the safety-net focus-walk Kiface() dispatch TU. Gated by
KICAD_WASM_MERGED_EDITOR (kicad submodule bump carries the fork side: per-engine
Kiface/getter binding + ODR renames + dual-kiface launcher).
- wasm/bindings/: per-editor collab entries renamed pcbCollab*/schCollab* (JS names
unchanged); duplicate kicadOpenFile/kicadCollabOnSave + shared-name registrations
guarded behind KICAD_MERGED_EMBIND; new kicad_editor_embind.cpp registers each
shared JS name once, dispatching on the live frame.
- Build: kicad_editor app (build wrapper, target case arms, 3-object embind compile
with the ABI-critical flags, STUB_APP=pcbnew); docker/build.sh "all" =
kicad_editor calculator pl_editor gerbview (pcbnew/eeschema stay as explicit debug
apps); scripts/kicad/audit-merged-symbols.sh = repeatable ODR-collision audit (run
on kicad bumps).
- Frontend: Bundle type (bundle ≠ tool); TOOL_BUNDLE maps all four editors to
kicad_editor; explicit --frame tokens for pcbnew (pcb) and eeschema (sch); publish
list = the 4 real bundles.
- Tests/CI: five harnesses load kicad_editor.js with explicit frame tokens;
PCBNEW_FAMILY_SPECS renamed BIG_MODULE_SPECS + the 8 eeschema-family specs (they
now boot the merged module — SpiderMonkey x86 CI OOM routing); frame-runtime spec
covers all four frames from the one bundle.
Validated so far: frame-runtime 4/4 (each frame boots with the right title, no
aborts, no duplicate embind registration); 24-spec merged-module regression green;
3D raytracer renders. Known pre-existing failure: 3d-viewer title-bar drag deadlock,
fixed on main by 7630c7e (2N+8 pthread pre-warm) — picked up by the follow-up rebase.

- 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.

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.

A board-level graphic text (Place→Text) lands in Drawings() and would otherwise hit the
same asyncify-fragile (kicad_pcb …) envelope-blob wall as via/zone on add. So PCB_TEXT
reconstructs NATIVELY: itemToJson emits size/thickness/angle plus horizontal & vertical
justification, mirror, and bold/italic (the text string was already emitted for any
EDA_TEXT); makeItem builds a fresh PCB_TEXT and restores all of them. flushDiff skips the
blob for PCB_TEXT_T. Footprint child text is unaffected — it syncs by move, and its add
is carried by the footprint blob.
Justification matters: it anchors the glyphs relative to the text POSITION, so without it
a left-justified text reconstructed centered on the peer and rendered visibly offset even
though GetPosition() matched (which is why the anchor-only headless check missed it).
Verified two-tab in the real app: a left/bottom-justified bold text added in tab A
reconstructs in tab B at the exact position with matching justification + string. Headless:
a board-text round-trip add test (sample text is left/bottom-justified) asserts the
position AND that hjust/vjust/text round-trip. 7 passed, 1 skipped, 0 aborts.

Footprint add reconstructs from the bare `(footprint …)` s-expr clipboard blob via
CLIPBOARD_IO (SetWriter/SetReader redirect it to a string for headless/wasm). The
non-footprint `(kicad_pcb …)` envelope parse (parseBOARD) is asyncify-fragile in wasm
— commit.Add of an envelope-parsed item silently stages nothing and subsequent virtual
dispatch traps ("index out of bounds"), the same wall that deferred the eeschema symbol
blob — so vias and zones reconstruct NATIVELY instead: itemToJson emits drill/layer-pair
for a PCB_VIA and the outline polygon for a ZONE, and makeItem builds a fresh PCB_VIA /
ZONE. flushDiff attaches the blob only to types that need it (footprints/board graphics);
tracks/vias/zones skip it. Includes the dangling-parent fix for the envelope path
(SetParent before delete) which footprints don't hit.
Build: kicad_clipboard.h pulls in the generated pcb_lexer.h (emitted into the common
build subdir by make_lexer) — added -I${KICAD_BUILD}/common to the embind include path.
Tests: sample board gains a via + zone; snapshot asserts their native fields are emitted,
and three round-trip add tests (footprint via blob, via/zone native) delete then re-add
each by uuid and confirm it returns at the same position. 6 passed, 1 skipped, 0 aborts.

Bug 1 — footprint child text now syncs. forEachTopItem also visits each footprint's
TEXT children by their own uuid (GetFields() PCB_FIELDs + GraphicalItems() PCB_TEXT),
so moving a silkscreen reference/value/user text — which leaves the footprint origin
unchanged — produces a diff. Apply needed only a guard: the removed loop skips items
with a parent footprint (a footprint delete cascades to its children, so don't
double-remove). ResolveItem already resolves child uuids and BOARD_COMMIT::undoLevelItem
rolls a child Modify up to the footprint, so Modify+SetPosition (in the existing
COROUTINE) just works. itemToJson now carries text for EDA_TEXT items.
Bug 2 — kicadCollabTestMoveFirst no longer no-ops. Its CallAfter now runs the move
inside a COROUTINE fiber (like doApply) so the virtual BOARD_ITEM::Move dispatches
instead of asyncify-no-opping.
Tests: sample board gains a footprint with a Reference field + user fp_text; snapshot
test asserts the footprint and both text children are emitted by uuid; a new test
moves each child by uuid and asserts the footprint origin stays put. 3 pass, 1 skipped.
Verified two-tab in the real app: C1's reference text move syncs A->B, no footprint moves.

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.
