The batched-emit fix still lost segments on a large connected drag (peer
dropped the P3-C1 wire). Deeper cause: the SCHEMATIC_LISTENER fires in
pushSchEdit BEFORE RecalculateConnections (sch_commit.cpp ~402 vs ~430), so
every emit was pre-cleanup RAW geometry; the cleanup that follows (merge
collinear wires, drop/split junctions) was never broadcast. The peer rebuilt
the raw edit and ran its own cleanup over a different dirty scope, so the two
peers cleaned up differently and the peer lost segments.
Replace the listener-list emit with a post-settle full-model snapshot DIFF
(snapshotByUuid), flushed via CallAfter once Push (cleanup included) returns —
capturing tab A's final, already-clean geometry. The peer applies that and
re-cleaning already-clean geometry is idempotent, so they converge. The native
listener is now just a change trigger. g_baseline holds the last-broadcast
state; doApply and kicadCollabSnapshot rebaseline so applied/seed items aren't
re-broadcast (echo). Mirrors pl_editor's snapshot-differ; no kicad-fork change.
Verified two-tab, rigorously (real edit: tabA state changed AND tabA===tabB
byte-for-byte): a wire reroute plus U1A/U1B/C2 symbol drags all converge
exactly. eeschema-collab + eeschema-ui suites green.

A single SCH_COMMIT::Push fires OnItemsAdded/Removed/Changed separately and
synchronously, then RecalculateConnections once. COLLAB_LISTENER emitted each
category as its own delta, so the peer applied one atomic edit as three separate
commits, each with its own connectivity recompute. On a large connected drag the
junction at the wires' new crossing (added) was applied before the wires moved
(changed) -> dangling junction -> the peer's cleanup deleted it (lost segments).
COLLAB_LISTENER now buffers added/changed/removed (serialized in each synchronous
callback) and flushes one combined delta after Push returns, coalesced via
CallAfter. doApply applies it atomically removed->changed->added in a single
commit with one recompute, so the junction survives. Verified two-tab: a G-drag
of U1A that previously left the peer at 74 items / 7 junctions now emits one
delta {a:1,c:4,r:1} and both tabs converge at 75 / 8.

Thrust A — dialogs render top-left with OK clipped in the WEB app (not the
test harness): root cause was the React shell missing the .window /
.window-canvas CSS that wx.js relies on (it positions each dialog div via
inline left/top, which need position:absolute). Added the rules to
web/apps/frontend/src/index.css. Native draw-text now works end-to-end;
symbol/power choosers render (placing still blocked by absent libraries).
Thrust B — collab apply of a newly-added SCH_SHAPE trapped in KiCad core
(SCH_COMMIT::Push CHT_ADD -> GAL view->Add, an asyncify invoke_* mis-dispatch)
because doApply ran off a fiber stack. doApply now runs inside a COROUTINE so
it executes on a libcontext fiber, the same context native draws use; the add
dispatches correctly. Re-enabled the SCH_SHAPE converter (rect/circle). Added
thirdparty/libcontext to the embind include path (tool/coroutine.h needs it).
Verified two-tab: rectangle + circle drawn in tab A sync + render in tab B.
Extended eeschema-collab.spec.ts apply test with a SCH_SHAPE add.
All changes root-repo only; kicad and wxwidgets forks untouched.

Captures milestone-3 state + the known in-app bugs (text-add freeze, deletes not
applying, SCH_SHAPE no sync, partial wire-move convergence) + the build/test/verify
workflow, so a fresh session can pick up the eeschema collab apply work.

Update 0002 to note the bridge lives in wasm/bindings/pl_editor_embind.cpp (not the
kicad fork) per CLAUDE.md, keeping fork divergence to the single OnModify hook; CRDT
is a uuid-keyed Y.Map; verification is the two-tab BroadcastChannel e2e.
