- 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.
