+- **Memory leak: validation maps pinned every resource per frame** —
+  `SetBindGroup` copied every bound buffer and texture into encoder maps per draw
+  call (O(bindings × draws)). Validation maps were never cleared after Submit or
+  Release, pinning BindGroup objects indefinitely. Now tracks bind groups only;
+  `validateCommandBufferForSubmit` walks `boundBuffers`/`boundTextures` transitively.
+  `dropUsedSets()` clears maps in both `postSubmit` and `Release()`.
+  Contributor: @samyfodil (#291)
+
+- **Validation error precedence: buffer/texture errors beat bind group errors** —
+  Two-pass validation: first walks all bound resources from all bind groups, then
+  checks `bg.released`. Deterministic regardless of map iteration order. Matches
+  Rust wgpu ordering (buffers 1780-1808, bind groups 1815-1817). (#291)
