The spec's boot gates (canvas, registry, title) are all wx-side and go
live seconds before WasmTool drops its opaque boot overlay (ready only
flips after the collab seed + waitForWxUi). The Tools click landed on
the overlay, the popup never opened, and the menu-item wait timed out —
flaky on CI (the 1s title poll sometimes samples after overlay unmount),
100% locally. Add the inset-0.z-30 count-0 guard the chrome-toggle /
tool-switch / quit-* specs already use.
Verified: web-chromium 5/5, web-firefox 8/9 (was 0/5, 0/1). The one
remaining firefox failure is a distinct pre-existing wasm trap on the
CvPcb-open path (EVT.MENU dispatch → "index out of bounds" in a worker),
same signature as the eeschema-fp-selector CI trap — now known to
reproduce on macOS real GL too. Left as a TODO(cvpcb-open-trap) in the
spec; needs a debug-symbol repro.

The eeschema symbol-chooser footprint-selector test was marked
test.fail() on CI for a software-GL wasm "index out of bounds" trap.
That trap no longer fires (SwiftShader retired + serial-inline footprint
load fix), so the test passes on both engines and the expected-fail
marker was flipping the run red ("expected to fail, but passed").

The three page.waitForTimeout calls in eeschema-assign-footprints.spec.ts
are legitimate interaction dwells (two poll intervals that pump the wx
event loop inside asserting loops, one first-paint settle before a
screenshot), but were unannotated, so the determinism guard failed CI.
Mark each with a `dwell:` note per tests/TESTING.md.

Board Setup -> "Import Settings from Another Board..." -> browse opens three
nested wx modals; a click inside the top file dialog leaked to the Import
Settings dialog beneath it (its checkbox toggled). New Playwright e2e repro
asserts the click no longer reaches the shadowed modal, with a sanity phase
proving it does toggle when Import Settings is the topmost modal. Lives in
tests/kicad/ so the kicad-firefox/kicad-chromium projects run it on both
engines automatically (no routing list; lint-ci-coverage satisfied).
Bumps wxwidgets to the JS-layer input barrier fix (build/wasm/wx.js) that
stops the click leaking through the shadowed dialog's live DOM controls.

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).

Quit used to mimic the Back button (history.back() whenever a referrer
existed), but every in-app entry and every tool switch is a hard
location.assign that pushes a history entry — so after schematic ⇄ pcb
switches, one step back is another editor, not the page the user left from.
Quit now navigates to the project overview explicitly (projectPath; "/" for
lib editors), which also covers deep links uniformly.
New VITE_QUIT_ORIGIN ("" ⇒ same-origin) lets the backed editor deployment
exit to the management app's project page instead of the standalone's own;
build-editor.mjs sets it (override with --app-origin).

Tools → "Switch to PCB Editor" is a hard location.assign that stacks a second
editor history entry, so a Back-style quit lands in the previous editor
instead of leaving for the project overview. Red until the quit hook stops

- defaultKicadPro() template + synthesizeProjectFile() writes a minimal
<stem>.kicad_pro into MEMFS when a board/schematic opens without one, so KiCad
runs a real project (self-heals legacy fileless projects).
- NewFileDialog creates the .kicad_pro companion alongside a new board/schematic.
- sibling-restage.ts: pcbnew sessions subscribe to sibling .kicad_sch collab rooms
as invisible observers and re-stage MEMFS on update (restageFile extracted from
syncProjectToMemfs), so a sync reads live schematic data, not the boot snapshot.
- tests/kicad/project-sync.spec.ts (2 e2e) + sibling-restage.test.ts (5 unit).
- Bump kicad pointer (SCH-from-PCB sync gate + hidden player + .kicad_pro save hook).

One circular FAB (peer-count badge) replaces the top-right overlay row:
draggable anywhere (pointer capture, 4px click-vs-drag threshold — the
comment-pin pattern), position persisted in localStorage, panel opens
toward screen center and stacks composable sections — roster, source chip,
view-only pill, follow row, comments, chrome toggle. Renders at z-50 above
everything (decided: covers wx dialogs; trivially dismissed via click-away/
Esc/drag). CommentLayer portals its bar + list panel into the menu's
comments slot; pins/popovers/composer/click-catcher stay canvas-anchored.
The FAB is the chrome-hidden survivor. e2e specs updated with an
openOverlayMenu helper (panel is closed by default, click-away closes it).
NOTE: Playwright suites updated but not executed here (no local WASM
artifacts) — verify on CI / next session.

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.

Tools → "Switch to PCB Editor" in a project with no .kicad_pcb (e.g. created
from a lone schematic) did nothing: the nav hook found no file for the target
tool and returned false. Now a session that can persist (ToolPage passes the
new createFile prop) writes the templated counterpart via
createProjectFileIfMissing — no download fallback, and it re-checks existence
so a collaborator's file is never clobbered — then navigates to it, matching
native KiCad (pcbnew opens a new board at the derived path). Sessions that
can't persist (read-only viewers, scratch/local-folder) keep the logged no-op.
Also latch the quit dispatcher off before every deliberate tool-switch
navigation (markDeliberateNavigation): the wx port's UnloadCallback runs on
BEFOREUNLOAD and closes the top frame the moment the navigation starts, so
the quit hook history.back()'d over the in-flight navigation — the pagehide
latch is too late (it only fires at commit time).
e2e: new tests/web/tool-switch-missing-file.spec.ts reproduces the flow via a
browser-local (IDB) project created from the home page; playwright-web config
gains VITE_LOCAL_PROJECTS=idb and derives STANDALONE_PORT/CORS_ORIGIN from
WEB_APP_URL (runs the suite past a squatted :3048); both vars declared in
web/turbo.json globalEnv (turbo strict-env strips undeclared vars). Includes
the previously-uncommitted tool-switch spec repairs (URL grammar + z-30
boot-overlay wait).

skip-when-unbuilt): resave version bump + relint clean for board/schematic/

green. Also bumps pcbjam-shared (T3 unit tests).

The quit hook only history.back()ed on a SAME-ORIGIN referrer, so the
primary closed-deploy entry — app.pcbjam.com deep-linking into
editor.pcbjam.com (cross-origin) — fell through to the editor's own
project view instead of returning to the app. Quit is Back-button
semantics (3a2255c): any non-empty referrer with in-tab history now
goes back; deep links / fresh tabs (no referrer) keep the project-page
fallback. Verified live against the closed stack: :3047 → editor →
quit lands back on :3047; a direct editor URL still falls back to the
editor's project overview.

720cff5 added occ-export-models.spec.ts (boots the ~190MB merged pcbnew
module, prefetches 17 model bodies, runs a 13MB OCC STEP export in the
occ_service worker — twice, serial) but never listed it in BIG_MODULE_SPECS,
so on CI it ran on the firefox project: headed under Xvfb with the
baseline-only WASM JIT and llvmpipe. That CPU storm ran concurrently with
the chromium-ci pool and starved the SwiftShader 3D-viewer opens past their
180s cap — 3d-viewer.spec:299 (edge-resize) timed out at openThreeDViewer in
runs 29076702564 (main) and 29090433643 (PR), and 29076702564 also dropped
occ-export.spec:105's menu click. In both red runs the last console line
before the 180s silence is the misrouted spec's export.
Add it to BIG_MODULE_SPECS like every other pcbnew.html-booting spec: it now
runs on chromium-ci (V8, headless SwiftShader) and firefox ignores it
(verified with CI=1 playwright --list).

The occ_service export worker has its own MEMFS — the editor's lazily-fetched
lib models were invisible there, so every export was a bare board (54
"Could not add 3D model" warnings on pic_programmer, 2 STEP products).
- models-bridge: collectBoardModelFiles(boardText) — scan refs, ensure via
the 0004 sparse source (IDB/R2, wrl->step fallback), read staged bytes
back, dedupe by real staged path.
- occ-service.ts: attach the collected models to every export request
(best-effort — prefetch failure still exports, misses reported by the
exporter); transfer the body buffers.
- occ-worker.js (shared app/harness): pass req.models through to occExport.
- occ_service_main.cpp: occExport(board, params, models) stages each entry
under PCBJAM_3D::MODELS_MEMFS_ROOT (path-sanitized) for the exporter's
staged-model probe (kicad 83645275ac), removed again after the export.
- tests: harness occ stub mirrors the prefetch against the page kicadLibs
provider + captures report/productCount; new occ-export-models.spec.ts
guards the delivery (green companion pins preconditions; guard asserts 0
missing lib models + component PRODUCTs). pic_programmer: 17/17 staged,
87 products @ 13.3 MB (was 2 @ 402 KB). models-bridge unit tests 13/13.
Known remainder (0007 step 4): project-local ${KIPRJMOD} refs still drop.

emitViewportIfChanged deduped on scale+center only, so a canvas SIZE change
(boot layout settling after the bind-time seed, window resize) never re-pushed
{w,h} to JS. CommentLayer's worldToScreen maps through h/2, so every DOM pin
hit target (and its hover ring) sat vertically offset from its GAL dot by
exactly delta-h/2 css-px until the next pan/zoom finally passed the dedupe.
Size now participates in the dedupe and wxEVT_SIZE re-pushes post-layout
(CallAfter, after the GAL's own onSize). New regression e2e
comments-viewport-resize.spec.ts asserts the DOM pin re-aligns with GAL truth
(fresh kicadCollabGetViewport) across a window resize with no pan/zoom.

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.

Chrome visibility is now a runtime toggle on any device instead of being
device-wired: mobile defaults to canvas-only, desktop to full UI, and the
floating top-right button (or Figma's Cmd/Ctrl+\ chord — free in KiCad,
only bare \ is bound) flips between them live.
- chrome-visibility.ts: module-global store (default isMobileMode(),
session-only) + pure hotkey matcher (rejects AltGr backslash + repeats)
- WasmTool: capture-phase hotkey (stopped before the wx layer), floating
toggle pill (matches the comment FAB design), useLayoutEffect apply with
sync first call + retry; overlays follow the toggle, capability-gated on
the kicad_editor bundle's kicadSetChrome export
- boot.ts mobile opt now installs touch gestures only
- kicadSetChrome: frame-keyed hide-time snapshot so restore re-shows ONLY
what hide took away (blanket Show(true) surfaced KiCad's default-hidden
Search/Properties/Net-Inspector panes); toolbars-only fallback otherwise
- tests: chrome-toggle.spec.ts (desktop hide/restore + geometric
restore-exactness ±3px), mobile toggle round-trip, 12 new unit tests,
test:web:mobile npm script

On a mobile device (or ?mobile=1) the editors run canvas-only with touch
gestures driving the view:
- touch-gestures.ts: pure recognizer (unit-tested) + DOM shim installed in
boot preRun — one-finger drag → synthetic middle-drag (pan), pinch →
synthetic wheel at the centroid (zoom-to-cursor), tap → left click.
preRun registration order is what lets stopImmediatePropagation suppress
the wx layer's single-finger→LEFT-drag touch mapping.
- kicadSetChrome(bool) embind: hides all AUI panes except DrawFrame + the
menubar/status bar via generic wx APIs (kicad fork untouched); boot polls
it after runtime init. Pairs with the wxwidgets IsShown layout fix.
- mobile-mode.ts: ?mobile=1/0 override or UA-CH/coarse-pointer autodetect;
shell hides its overlays and the inherent-to-mobile preflight warnings.
- e2e: mobile-chromium project (Pixel 7) + 4 specs (chrome-less, tap,
pinch, pan) with screenshot-invertibility assertions; also fixes
tool-switch.spec's stale pre-scope-refactor URLs (was broken on main).

Every KiCad editor's File→Quit used to destroy the wx top frame and
notify nobody, leaving the SPA stranded on the editor URL with a dead
canvas. It now behaves like the browser Back button: return to wherever
the user entered the editor from (project page, or a previous editor).
- WasmTool installs window.wxAppTopWindowClosed (the wx wasm port fires it
from the main frame's destructor — see the wxwidgets pointer bump). On a
real quit it history.back()s when there is same-origin in-app history,
else location.assign()s the project page (or "/" for lib editors).
- The navigation is deferred one task (setTimeout 0): it fires inside the
C++ destructor via EM_ASM under Asyncify, and a cross-document
location.assign() started there is aborted by the continuing teardown;
only same-document history.back() survives synchronously.
- Latches off on pagehide (the port also closes the frame on page unload
via UnloadCallback) and reloads on a bfcache pageshow so Forward never
restores a dead frame.
- e2e: quit-to-project.spec.ts covers both the history-back and the
deep-link fallback paths.
No kicad changes — the whole hook lives in the wxWidgets wasm port and the
web app, keeping the kicad fork clean for upstream syncs.

The cursor-emit tests asserted a fixed <25 emits for 30 awaited mouse
moves, assuming the sweep outpaces the 50 ms throttle. On a loaded
Ubicloud runner each Playwright->Firefox->WASM round-trip can straddle
a throttle window, so 28/30 moves emitted and the test failed (twice on
main, once from a docs-only commit).
Bound by measured sweep duration instead: one emit per 50 ms window,
+1 leading edge, +2 slack. Fast machines get a tighter bound (~9-13);
slow runners scale with actual elapsed time. A broken throttle still
fails.

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.

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);

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

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}

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 /

clientID keeps, the other re-claims), same-user tabs adopt one color,
claims are sticky across eeschema sheet rebinds (skeletons reuse them).
colorOf(userId) resolves live colors; comment pins/popovers follow it
(offline authors fall back to the hash). +2 unit tests (verified live:
alice=slot0, bob=slot1, roster/pins consistent).
- CommentLayer: single comment icon expanding into a horizontal bar — new
comment · list · show/hide all (eye empties the GAL pin set + DOM targets;
re-shown on new-comment/panel-jump). Pins are DRAGGABLE: live LWW anchor
writes while dragging (peers + the GAL dot follow), nearest-item re-snap on
drop, click-vs-drag by 4px threshold (verified live: drag synced to the
peer tab exactly). Shared setThreadAnchor + controller moveThread/
setPinsVisible/colorFor.
- collab_presence_style.h: chip text color by background luminance (dark on
light chips, white on dark — BitmapText draws with the stroke color).
- comments/presence-roster e2e updated for the bar + passing; collab units
56/56; shared 122/122; shared pointer bump.

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
stay green; shared pointer bump (0004 model).

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.
Verified live: two tabs over partykit — peer cursor cross + label + selection
outline visible on the other tab's canvas.

The merged kicad_editor bundle made the chooser's footprint side reachable
from a schematic session; this wires up the data:
- boot.ts/constants.ts: every kicad_editor frame seeds BOTH sym-lib-table and
fp-lib-table (+ placeholder files; a created user lib joins both lists) —
the eeschema frame used to write fp-lib-table empty, leaving the selector
dead. TOOL_LIB_KIND remains only the presync/primary-kind lever.
- publish-libs.ts + kicad-pretty.ts: publish fp-index.json per tag —
[name, uniquePadCount] per footprint (countUniquePads mirrors KiCad's
GetUniquePadCount(DO_NOT_INCLUDE_NPTH)); index-only top-up mode for
already-published immutable tags.
- source.ts/cdn-source.ts: new bridge op "index" (source-global, dispatched
before the lib-id parse) + LibsSource.getFpIndex; the CDN source fetches
<tag>/fp-index.json once (404 ⇒ null ⇒ C++ default-only fallback).
- dev-demo.mjs: --libs-local serves a local publish-libs layout same-origin
at /libs-cdn (mirrors --models-local).
- tests/web/eeschema-fp-selector.spec.ts: e2e — chooser opens in --frame=sch,
selector fills from ONE index crossing, clicking a row per-item-gets the
body and the cross-face GAL preview renders; adaptive for index-less
sources (asserts crash-free default-only selector).
Submodule bumps: kicad (index-backed filterFootprints + preview AsyncLoad
fix + modal-pump crash guard), wxwidgets (modal pump logs e.stack).

waitForRenderStable now runs two phases (still entirely in-page, still just the
canvas hash — no CDP screenshots):
1. Fast per-rAF convergence — hash every animation frame until stableFrames are
identical (~48ms). Catches high-frequency motion, cheap.
2. Wide confirmation — then re-hash confirmFrames times, each `interval` ms apart
(default 2 × 250ms ≈ 500ms). A slow async repaint (e.g. a file list arriving
after an asyncify readdir) that a few 16ms frames would sail past now forces a
reset back to phase 1.
This closes the hole where three ~16ms samples could declare "settled" ~200ms
before a delayed paint lands. Genuinely-animating states still never converge and
are captured at the timeout, as before.
Cost (local, 4 workers): e2e 62s->103s, kicad 155s->212s — pure waiting, no extra
CPU. Both suites green (e2e 340, kicad 92). Tunable via confirmFrames/interval.

The determinism conversion silently dropped/renamed screenshots vs the committed
baselines, so CI flagged ~35 baselines as "removed". Restore them:
- pl_editor-*: re-add the "pl_editor-" prefix the conversion dropped (5).
- Buffer screenshots that lost their path: (eeschema draw-wires/loaded-css,
pcbnew draw-lines/loaded-css, pcbnew-move, dark-mode, eeschema-crosshair,
aui-resize) re-add path:'test-results/<name>' so they SAVE and still feed the
in-test pixel-diff analysis (17).
- Dropped animating/loading captures re-added via stableShot / raw screenshot:
timer-03/05/06, dialogs-timer-running/started, wxgrid-02/03, 01-loading (7).
Delete 5 obsolete wizard baselines (eeschema/gerbview/pl_editor/symbol_editor/
generic -wizard-00-initial): every app is now seeded to bypass the first-run
setup wizard (that was the point of removing the wizard for/if loop), so those
states are no longer produced — pl_editor.spec asserts "no wizard appears"
instead.
Net: every committed baseline has a producer again (0 "removed"); determinism
guard green; affected specs pass (e2e 40, kicad 12) and emit the restored PNGs.

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.

Miss 08A: the binding stores wire-carried (lib_symbols …) definitions in
kdoc_libsymbols and prefixes them on apply wires — a joiner that never saw a
symbol adopts it WITH its definition (new e2e ysync-libsymbols.spec.ts).
Miss 08B: registerSaveHook gains onSavedText; WasmTool routes saved-file text
to syncLayoutToY (per sheet room via the manager's syncLayoutFromSave, or the
single-room doc) so title block / paper / setup edits converge instead of
drifting. Opt 12 (TS half): zod off the observer hot path (yToItemUnchecked),
children index built once per conversion. Opt 13: seed()'s adopt diffs the
editor snapshot against the doc view and applies only the doc-authoritative
difference — clean rebinds apply nothing, the adopt undo entry shrinks to the
real changed set. Opt 14 deliberately deferred (doc 18). All TS-side; no wasm
rebuild (the C++ blob/findLib sides already carried definitions).
Verified: shared 107, standalone 79 (+2 known pre-existing wasm-assets),
ysync e2e 21/21 chromium, collab regression 21/3-skip firefox.
Bumps: web/pcbjam-shared (lib_symbols channel + syncLayoutToY + opts).

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).

The three 3D-viewer shots changed because the specs now screenshot the
COMPLETED render (pixel-gated waitForThreeDRender) instead of a fixed-sleep
mid-render frame. The rest is the accumulated unpromoted backlog: eeschema/
symbol-editor drift, and first-ever baselines for the models-spec renders
(tail re-enabled in 561d050), frame-runtime, occ-export/probe and
xface-preferences from earlier merges.

The 3d-webgl merge (kicad eb13ff3bdc: the viewer now defaults to the real
OpenGL renderer via wasm/gl1, and occ-split moves STEP parsing into the
occ_service worker) made the raytracer-era orchestration on this branch moot —
main's chromium-ci phase is green at 15-way parallelism (28666407570 /
28698861536). Drop what no longer earns its complexity, keep the diagnostics,
fix main's live flake, and make the deadlock spec test what it was written for.
- REVERT the chromium-ci-3d serial project, the two-phase test:kicad:ci, the
SwiftShader GPU-process flags, and the resize-drag/models skips: config and
package.json are byte-for-byte back to main's shape. The raytracer contention
they guarded is no longer on the CI path.
- FIX main's live flake: run 28698861536 is green only via retry
(3d-viewer.spec:26 flaky) and 28666407570's deadlock red sampled an ALL-ZERO
pixel signature — the viewer's first frame lags the canvas's creation on
software WebGL under parallel load, and sampling too early reads an all-black
backbuffer. New waitForThreeDRender() gates render assertions on actual
pixels (1s-interval full-frame CPU reads) instead of fixed sleeps, used by
3d-viewer.spec:26 and the models render tail.
- KEEP the storm-proofed samplers (one full-frame getImageData on a
willReadFrequently canvas replacing 256 per-pixel GPU round-trips per sample
— the "GPU stall due to ReadPixels" trigger) and the logThreeDDiag
instrumentation: engine-independent, and they de-risk every remaining
software-GL pixel read.
- models spec: bridge assertions stay front-loaded (the protocol regression
signal is independent of the render); the occ_service parse verdict is now
POLLED — it lands async relative to the bridge ensures, so asserting it
immediately raced the worker; the render tail runs again everywhere. (The
pre-webgl raytracer+models renderer-death documented in a17f3be does not
affect the OpenGL default path — the raytracer-toggle+models combination
remains untested product surface, tracked outside this branch.)
- deadlock spec: the deadlock it guards is raytracer-specific and the viewer
now defaults to OpenGL — on the GL engine it either passes vacuously (fast
renders make every liveness assertion trivial, 28698861536) or fails on the
black first frame (28666407570). It now flips the engine via the "Use
raytracing" toolbar toggle (loud assert if the toggle moved) and
cross-checks engagement by requiring the canvas pixels to CHANGE after the
flip with no input in between (the raytraced frame is lit differently; a GL
re-render reproduces identical pixels; heap growth is unusable — mimalloc
satisfies the raytracer from freed arena pages). That guard immediately
caught a REAL defect: on the webgl-era wasm build the toggle is INERT (the
click lands and "Reload time" updates, but the canvas never changes —
suspects: DoRePaint's silent catch(runtime_error) freezing the canvas after
a raytracer Redraw throw, or ToggleRaytracing writing m_boardAdapter.m_Cfg
while RenderEngineChanged() reads GetAppSettings<…>(), possibly different
instances in the merged bundle). The spec is therefore test.skip-annotated
as a KNOWN ISSUE with the full engine-force machinery in place — unskipping
it self-validates the product fix. The CI-skip also stays (raytracer
liveness needs real-GPU pacing; the Worker-boot deadlock mechanism is
covered on CI by the standalone wx harnesses).
- 180s viewer-open waits kept as pure CI headroom (never slow a passing run).

The headed Mesa-llvmpipe switch (ce44636) was built on a misdiagnosis. With
--use-gl=angle --use-angle=gl under Xvfb, Chromium gets NO WebGL AT ALL on the
GPU-less CI VM: runs 28652367347 + 28664038296 both log
`glcanvas count before opening 3D viewer: 0` (even the pcbnew board's own GAL
canvas fails to create) and every failure is the FIRST viewer-open wait timing
out. "Timeouts instead of crashes" meant no GL context existed to crash, not
that llvmpipe was stable-but-slow. The Mesa/GLX path works for the Firefox
project, but not for Chromium on this image.
Headless SwiftShader is the environment where GL provably works — the
serialized run 28649537489 opened the viewer and rendered/sampled 56 colours
(viewer:26/130/209 all passed single-tab). Its remaining failures split into
two families, each addressed on its own evidence:
1) SwiftShader GPU-process kills (deadlock spec's lost canvas/black frame):
- chromium-ci-3d back to headless + --enable-unsafe-swiftshader, plus
--disable-gpu-watchdog and --disable-gpu-process-crash-limit: heavy churn
stalls the software-GL GPU process until the watchdog shoots it
(CONTEXT_LOST -> removed GL canvas -> "Target crashed"); with the watchdog
off a slow op completes, and without the crash limit a lost GPU process
keeps restarting for later tests. Same args locally (no-ops on a healthy
real GPU).
- Storm-proof every canvas sampler (3d-viewer, models, deadlock specs): one
full-frame getImageData on a willReadFrequently (CPU-backed) 2D canvas +
JS grid sampling, replacing 256 per-pixel getImageData GPU round-trips per
sample — the "GPU stall due to ReadPixels" trigger, worst in the deadlock
spec's 1.5s-interval settle polling. Sampled pixels and sig order are
unchanged.
- edge-resize spec: keep the open + 5-resize-handles assertions on CI, then
test.skip the drag — each resize step re-raytraces synchronously on the
wasm main thread and the 12-step drag blocked mouse.move past the 240s
budget even single-tab. Real-GPU-paced; still runs locally (deadlock
spec's CI-skip from d9900fe unchanged, same rationale).
2) KNOWN PRODUCT BUG uncovered in the models spec (NOT SwiftShader, NOT CI):
raytracing a scene WITH component models kills the Chromium renderer
process outright ~6s after scene build — silent process death with a FLAT
wasm heap (531-637 MB watched at 2s intervals; not OOM), no console error,
no wasm abort, no crash report. Deterministic on a real GPU (5/5),
fixture-independent (700 KB USB-C and 61 KB USON-8 STEP crash identically);
the same death hits CI SwiftShader at ~66s. Board-only raytraces complete
and stay alive, so the bug is specific to the model path. The spec's one
historical green ended at raytrace-age ~6s — inside the death window by
luck; every CI run of it ever died. Fix here: front-load the bridge
assertions (ensure requests fire during scene BUILD, before the raytrace),
so protocol regressions still fail the suite everywhere, and test.skip the
render tail unconditionally with the bug documented at the skip site. The
raytrace->blit pipeline stays gated on CI by 3d-viewer.spec's board-only
render. Bug tracked for a dedicated fix session.
Correct the now-wrong llvmpipe comments (config, open-wait rationale, deadlock
skip reason). Expected CI matrix: viewer open/render/stacking/titlebar +
models-bridge on SwiftShader serial; edge-resize drag + camera-move deadlock
on real GPUs locally; the Worker-boot deadlock mechanism stays covered on CI
by the standalone wx harnesses.
Locally validated on a real GPU (--project=chromium): 5 passed + 1 skipped
(the documented models render tail).
