+- Single-line and rectangle-side dimensioning: keep endpoints reachable after Fit when the
+  Sketch Palette is open; support selecting a line or its two endpoints, with typed creation
+  committed as one undo step and cancellation leaving the sketch unchanged.
+- Contextual error reporting: a **Create Issue** action beside feature errors opens a
+  reviewable GitHub issue draft with the error, operation settings, build diagnostics and
+  useful reproduction context. Include relevant screenshots or a small reproduction when
+  they make a geometry failure or unexpected result easier to understand.
