+## [1.2.1] - 2026-03-17
+
+### Fixed
+
+- **Ground selection box** — tightened to match visible symbol bounds instead of oversized PNG frame
+- **Rotation-aware hit-testing** — ground elements now respond correctly to click/drag at all orientations (0°, 90°, 180°, 270°) by inverse-rotating the mouse into local frame
+- **Element-over-wire selection priority** — two-pass scan in `findElementAtPosition` ensures components always win over overlapping wires
+- **Drag-lock contract** — only selected elements can be dragged; `DragElementCommand` skips non-selected elements when renderer is available
+- **Eliminated duplicated hit-test logic** — `GUIAdapter.findElementAt` now delegates to `CircuitRenderer.findElementAtPosition`
+
 ## [1.2.0] - 2026-02-20
