- 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.

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.
