 Phase 534 is GitHub #191 / `avalonia-node-map-lzy`, the lasso visual gesture feedback route selected after the public lasso pointer-mode activation path. This implementation slice keeps `NodeCanvasSelectionMode.Lasso` on the existing selection route and adds a transient lasso path on the existing `OverlayLayer` while the user drags. `UpdateLassoFeedback(...)`, `ClearLassoFeedback()`, and `LassoSelectionMode_RendersTransientFeedbackPathOnlyDuringDrag` guard that the path appears after the existing drag threshold and clears on release or capture loss without creating persistent whiteboard state. It keeps toolbar UX, lasso screenshot route, eraser behavior, rectangle/freehand drawing, whiteboard primitives, persistence, renderer-layer changes, screenshot manifest expansion, strict visual-baseline enforcement, retained API removal, and full React Flow whiteboard parity as explicit gaps.
 
+## Phase 535 Update

+Phase 535 is GitHub #193 / `avalonia-node-map-8l6`, the post-Phase-534 parity queue refresh. This docs/tests-only slice records Phase 534 as closed and turns the remaining whiteboard pressure into tracker-backed follow-up candidates for lasso screenshot proof, lasso toolbar UX/public activation ergonomics, eraser behavior/API feasibility, rectangle/freehand drawing primitives, and whiteboard persistence/render-layer readiness. It authorizes no runtime behavior changes, no public API changes, no UI redesign, no screenshot manifest expansion, no strict pixel baseline enforcement, no retained API removal, and no whiteboard implementation.

 ## Phase 489 Update
 
 Phase 489 closed GitHub #101 / `avalonia-node-map-6sc` through PR #102 as a renderer virtualization design spike on branch `perf/renderer-virtualization-spike`. This slice was docs/tests only: it defined the proof contract required before any future ItemsRepeater/Skia-style renderer virtualization, background graph index, or graph-size claim expansion. It made no public API change and no runtime change. The current evidence remains viewport-budgeted scene projection/rendering, not a true renderer virtualization contract; `xlarge` stays telemetry-only.
