+# Wire & Line Removal Feature
+
+## Description
+Remove power lines and wires using contour detection with line brush fallback.
+
+## Acceptance Criteria
+- [ ] User taps near wire with Wire tool selected
+- [ ] `VNDetectContoursRequest` returns all detected contours
+- [ ] ContourService scores contours and selects best wire-like match:
+  - Proximity to tap point
+  - Thin/elongated aspect ratio
+  - Straightness (low curvature)
+  - Length
+- [ ] Best contour highlighted for preview
+- [ ] Mask width configurable: default 6px, range 2-20px via slider
+- [ ] User confirms, mask expanded to configured width, inpaint executes
+- [ ] Line brush fallback when no contour detected:
+  - User switches to "Line brush" mode
+  - User draws along wire
+  - Consistent stroke width maintained
+  - Stroke becomes mask for inpainting
+- [ ] Multiple wires can be removed sequentially
+- [ ] Performance: contour detection < 300ms
+
+## Technical Notes
+- Power lines against sky have strong edges - ideal case
+- Scoring weights: proximity 0.3, aspect 0.3, straightness 0.2, length 0.2
+- Line brush should use touch velocity for smooth strokes
+- Consider Catmull-Rom spline for smooth line brush paths
+
+## Edge Cases
+- No wire-like contours found: "No lines detected. Use line brush" prompt
+- Wire against busy background (buildings, trees): likely needs line brush
+- Curved wires (drooping power lines): scoring allows moderate curvature
+- Wire crosses entire image: may need to process in segments
+- Multiple parallel wires: each tap selects one, remove sequentially
