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.

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
Spec: docs/features/collab-presence/0006 (closed repo).

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.
