83b3418778Bidirectional bridge between pl_editor's DS_DATA_MODEL and a Yjs doc, two same-origin
tabs syncing over BroadcastChannel. Full architecture in features/yjs-bridge/0001-0002.
C++ (wasm layer, wasm/bindings/pl_editor_embind.cpp — public DS_DATA_MODEL API only,
zero added fork divergence beyond the OnModify hook):
- snapshot-differ ChangeSource: diff model vs last-emitted snapshot on OnModify,
emit per-item delta JSON via EM_ASM window.kicadCollab.onDelta
- kicadCollabApply(json): apply remote delta by uuid — scalars (text/segment/rect)
by field, polygon/bitmap via SetPageLayout-append blob; reseed snapshot + HardRedraw
- kicadCollabSnapshot() (seed/baseline), s_applyingRemote echo guard, and a
kicadCollabTestAddText() PoC local-edit hook
- wire format: {added:[item],changed:[item],removed:[uuid]}, item = {id,type,...fields}
JS (web/apps/frontend/src/wasm/collab/, generic + schema-agnostic):
- reconciler: uuid-keyed Y.Map of per-item Y.Map; down = onDelta→Y, up = observe→apply,
origin-tagged echo suppression; seed-once join adopts the doc authoritatively
- broadcast-transport: minimal BroadcastChannel Yjs provider (query/state catch-up)
- WasmTool wiring behind ?collab=1 (pl_editor only); gated debug logging
Tests: tests/kicad/pl_editor-collab.spec.ts — single-page C++ contract (snapshot/apply
changed+removed+added/echo-suppression) + two-tab BroadcastChannel A<->B propagation.
Reconciler+yjs bundled via esbuild (tests/collab/build.mjs, npm run build:collab).
