- kicadOpenFile now holds wxWasmDispatchGuard (open_gate.h). It enters through
embind, so the interlock read "nothing parked" for the whole load and wx timers
dispatched into the half-built board — the residual prod "index out of bounds"
that survived the settle gate.
- new wasm/bindings/gerbview_embind.cpp (the bundle had no embind surface at all):
kicadOpenFile / kicadOpenFiles / kicadOpenFileBusy. Clicking one gerber opens the
whole fabrication set in its folder, since a lone layer is not a useful view.
- cross-app presence rejoins in the boot fan-out (network-only; the wasm-bound half
still waits for the open to settle) — it had been pushed behind the board load.
- tests: gerber-set selection units + a gerbview multi-file open e2e.

Opening a large board could kill the editor runtime outright: "index out of
bounds" / "unreachable executed" / "indirect call signature mismatch", after
which every later focus/key event trapped. Reported in prod against a big
uploaded board, and correlated by the reporter with the moment the presence
WebSocket connects.
That correlation is the tell. Presence/collab work enters the wasm through
runOnFiber -> COROUTINE::Call, i.e. emscripten_fiber_swap, whose stop_unwind
corrupts Asyncify's single currData slot when ANOTHER context is already
parked there. docs/features/async/13 pins the invariant: exactly one
unwind/rewind transition in flight, and prescribes "a single shared is-a-
transition-in-flight guard the pumps consult before re-driving".
Normally the slot is free when fibers drain: the main loop's per-frame
wxWasmYieldToBrowser completes every frame, so drainFibers runs between
yields. It is NOT free when a nested/modal pump tick drives ProcessEvents
while the chain that opened the modal is parked deeper down — precisely a big
board open (progress dialog over a parked load). The wx dispatch interlock
does not cover this: the modal parks deliberately zero its count so their own
pump may dispatch.
So gate the swap itself: drainFibers defers (re-CallAfter) while
asyncifyInFlight(). Bodies are viewport/overlay/apply work, so waiting out the
park costs latency, never correctness.

Since comments-ux 0002, WasmTool re-sends the shell theme through
kicadSetColorTheme on every boot; setColorTheme ran CommonSettingsChanged
unconditionally, which recreates the menubar/toolbars — and they come back
SHOWN, undoing the kicadSetChrome(false) the read-only viewer and mobile
canvas-only mode applied moments earlier (CI: read-only-editor +
mobile-editor "9 visible menu titles").
Two-part fix in pcbjam_theme:
- early-out when the requested theme AND the wx dark-chrome flag are
already applied — the every-boot re-send (still needed for warm
relaunches with stale MEMFS settings) becomes a true no-op;
- after a REAL apply, re-assert the hidden chrome via a hook the merged
image installs (kicadSetChrome(false) when the snapshot says hidden),
queued with CallAfter from inside the fiber body so FIFO lands it
behind the CallAfter-deferred ReCreateMenuBar. Covers viewers/mobile
users toggling dark mode mid-session.

Two generic (manufacturer-agnostic) pcbnew-side subcommands for platform
manufacturing plugins: --ipc356 (IPC-D-356 netlist via IPC356D_WRITER) and
--fab-components (board metrics + per-footprint placement/BOM JSON —
absolute board coords, consumers apply their own conventions). Bumps the
kicad submodule for the diet keep-back of export_d356.cpp.
Also closes a CI cache gap: wasm-cache-hash never hashed wasm/**, so a
pure wasm/cli change would cache-hit stale output — { dir: "wasm" } is
now an input (busts the cache once on landing).

Symbolized (HOIST_KEEP_NAMES=1): the trap is on the asyncify REWIND re-entering
the fiber — stack-local COROUTINE+body were destroyed when Call() returned
early on a park, so the rewind called through freed objects (latent UB in the
ORIGINAL fire-and-forget runOnFiber too). Heap-pinned FiberSlot + explicit
done flag + fiber-tail re-drain. Layer 2 (rewind interplay) still open —
fuzz stays fixme'd; pageerror stacks now captured in fuzz artifacts.

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.

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).

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.

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).

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

comments-viewport-resize.spec.ts asserts the DOM pin re-aligns with GAL truth

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.

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

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).

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

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);
cross-app + presence-kicad vitest suites

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.

- presence.ts: colors claimed by ARRIVAL ORDER — each client takes the lowest
free palette slot (no birthday-problem hash collisions; the best palette
colors go first; N ≤ palette-size editors always distinct). Coordination-
free: claims ride awareness; simultaneous-join collisions converge (lower
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.

- 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
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.

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).

- gl1_glu: gluCylinder/gluDisk/gluSphere per the SGI GLU reference
tessellation (sin/cos phase, strip emission order, pole fans — Apple's
GLU derives from the same source, so vertices match the goldens);
emission goes through the public glBegin/glVertex entry points so
quadrics record into display lists
- glLineWidth>1 one-time warning (browsers clamp to 1; affected coverage
stays under the parity floor — zero floors.json overrides needed)
- production link site: build-kicad-target.sh now compiles wasm/gl1 from
sources.txt and applies wrapped_symbols.txt --wrap flags (same manifests
as the test harness); kicad_editor's RENDER_3D_OPENGL links against the
real emulation layer instead of no-ops
- wasm/stubs/gl_ffp_stub.c deleted (role fully superseded; history in git)
- docs: 3d-regression README port-status section (floor-blind small
geometry + line-width caveats), harness comments de-red-stated
Parity: 47/47 under the 0.02 floor, zero overrides. Native golden path
byte-identical to bb0e238 (whose gate ran green) — scenarios/, native/,
baseline/, manifest, floors, spec all untouched by the port.

- display lists: literal command replay through the shim state machine
(state leaks + between-list material changes get GL semantics for free);
recorded glDrawArrays EAGERLY snapshots enabled client-memory arrays at
compile time (the renderer frees them right after glEndList) and records
buffer+offset for VBO-backed pointers
- client-array draws: shared AttribSource path packs client-memory arrays
into one scratch-VBO upload and binds user VBOs with original offsets
(GL_BYTE normals / GL_UNSIGNED_BYTE colors normalized per GL1)
- glDrawElements over user VBO/IBO passes indices through untouched
(ELEMENT_ARRAY_BUFFER never touched by the shim)
- state mutators (enable/bindTexture/blendFunc/lineWidth/alphaFunc) shared
between the __wrap interceptors and list replay
Parity: 44/47 under the 0.02 floor (was 20). Verified visually: mini-board
Tier-3 composite (mask translucency + stencil-punched TH holes), stencil
hole subtraction, alpha-tested seg-end discs, COMBINE const-alpha model
transparency, and post-machining reproducing the upstream countersink bug
(walls absent, matching the native golden). Remaining 3: camera-* trio
needing the M4 GLU quadrics (+5 small-geometry false-greens they share).

wasm/gl1: the GL1.x fixed-function emulation layer replacing the
gl_ffp_stub.c no-ops in the 3d-regression harness link. This batch:
- symbol split: 52 FFP-only entry points implemented; 10 Emscripten-owned
names intercepted via wasm-ld --wrap (sources.txt/wrapped_symbols.txt are
the shared manifests for both link sites; production hookup lands in M7)
- matrix stacks (MODELVIEW/PROJECTION, glGetFloatv readback), immediate
mode with all 8 GL1 primitive conversions, GL1-default state mirror
- full GL 1.5 Gouraud lighting uber-shader (eye-space light capture at
glLightfv time, color-material, two-side, COMBINE evaluator + alpha test
wired but inert until M3/M5)
- draw routing: FFP traffic identified by GL_VERTEX_ARRAY client state;
blit/2D-GAL draws pass through untouched
- display lists: correct glGenLists/glIsList existing-empty semantics;
recorder itself is M3 (recorded commands drop with a one-time warning)
Parity: 20/47 under the 0.02 floor, of which 12 verified genuinely
rendering (bg-gradient x2, bounding-box, half-open-cylinder, segment x2,
material x3, light x3 — eyeballed against baselines); the other 8 are
small-geometry scenarios whose missing GLU/display-list content sits under
the floor (become real in M3/M4).

Move OpenCASCADE out of the merged editor image into occ_service: a separate
emscripten module (-sASYNCIFY=0, MODULARIZE, in-container -Oz finalize, 2N+8
pre-warmed pthread pool) booted lazily in a dedicated Web Worker on the first
STEP export or STEP/IGES model parse. kicad_editor.wasm ~190 MB -> 130 MB;
sessions that never touch OCC never fetch its 57 MB. STEP export works in the
browser for the first time: the unchanged desktop dialog runs EXPORTER_STEP,
whose wasm shadow suspends into globalThis.occService and the export bytes go
straight to a browser download (never entering the editor heap). STEP/IGES 3D
models parse in the worker via the oce shadow (S3D WriteCache/ReadCache wire).
- wasm/occ-service/: service CMake target (hooked from the kicad fork's
top-level CMakeLists, wasm/editor pattern), embind entry
(occExport/occLoadModel), wxConfig pre-js.
- wasm/stubs/{exporter_step,oce_plugin}_stub.cpp: EM_ASYNC_JS worker bridges
(callee-shadowing; no caller #ifdefs).
- web/standalone: provider installed whenever the kicad_editor bundle boots
(cross-face safe); ONE shared worker-boot source occ-worker.js (vite ?raw;
the e2e stub reads the same file) — blob worker with locateFile absolutized
against the glue URL; export download-name guard.
- deps: OCC builds with RapidJSON so its glTF/GLB writer exists — pinned to
the vcpkg master snapshot 2025-02-26 (24b5e7a8b27f), the same code official
KiCad consumes via vcpkg.json's opencascade[rapidjson]; rapidjson's latest
tag (v1.1.0, 2016) is ill-formed under modern clang.
- tests: occ-export dialog e2e (lazy-fetch boundary + STEP download bytes),
occ-probe incl. a 9-format matrix (step/stpz/brep/xao/ply/stl/glb/u3d/pdf),
3d-viewer-models hard-asserts the worker parse; occ provider stub installed
ambiently by the kicad fixtures.
Validated against desktop kicad-cli 10.0.4: geometric exact equality (bbox
delta 0 um, volume delta 0.0000%) for STEP/GLB/STL/BREP/STPZ across three
boards and option sweeps — with desktop OCC 7.9 vs wasm OCC 7.8; PLY/XAO/PDF
structurally equal; U3D same-size (quantizer float LSBs differ). Full kicad
e2e green on Firefox and Chromium; standalone verified end to end (lazy fetch
only on the Export click; export.step 60,628 B ISO-10303-21; loadModel 700 KB
STEP -> 569 KB scenegraph cache).
