Excalidraw scene now mirrors the v5 routing model: - Clamps export as 12×12 grey rounded squares (BackgroundColor=#888888, StrokeColor=#555555, Roundness type 3). Distinct from the red IO marker diamonds so wall outlets vs. routing anchors stay readable. Frame_id propagates into the element's FrameID per the existing pattern. - Cable arrows include clamp positions as mid-vertices in the `points` array. Pre-grouped + sort.Slice-sorted by ord; each mid-vertex is added as an (x-fromAnchor.x, y-fromAnchor.y) offset. startBinding / endBinding still point at the from / to endpoint excalidraw_ids; mid-vertices are unbound (Excalidraw doesn't have per-vertex binding). - IDAssignment grows a Clamps map; PersistExcalidrawIDs accepts it and updates clamps.excalidraw_id on first export so re-exports reuse the same element ids (collab cursors / undo history survive). - Bundle-stripe overlay is **viewer-only** — Excalidraw can't represent gradient strokes losslessly, so we export individual cable arrows and let the in-app viewer derive the bundle viz. Tests: - TestBuildScene_ClampsRenderAsRectangles — 2 clamps → 2 rectangle elements + 2 ids in IDAssignment.Clamps. - TestBuildScene_ArrowPointsIncludeClamps — cable with 1 clamp → arrow.Points has 3 entries; middle vertex equals the clamp's position relative to fromAnchor. This closes the v5 slice plan (§11.10). Six slices, one branch, one redeploy below.
