Purpose
Ghost marker drag interaction for reshaping routes by inserting new waypoints mid-segment.
Requirements
Requirement: Ghost marker on route hover
The Planner SHALL display a transient ghost marker when the cursor is near the route polyline, allowing users to reshape the route by dragging.
Scenario: Ghost marker appears on hover
- WHEN the cursor moves within 15 pixels of the route polyline
- THEN a ghost marker (small blue circle) appears at the nearest route coordinate point
Scenario: Ghost marker disappears on leave
- WHEN the cursor moves more than 15 pixels away from the route polyline
- THEN the ghost marker disappears
Scenario: Drag ghost marker to reshape
- WHEN a user drags the ghost marker to a new position
- THEN a new waypoint is inserted between the two adjacent waypoints of the hovered segment, and the route recomputes through the new point
Scenario: Trailer lines during drag
- WHEN a user is dragging the ghost marker
- THEN dashed guide lines are shown connecting the ghost marker to the adjacent waypoints
Scenario: No text selection during drag
- WHEN a user drags the ghost marker
- THEN text selection is disabled on the page (via Leaflet's built-in L.Draggable)
Scenario: Reshape syncs to other participants
- WHEN a user reshapes the route by dragging the ghost marker
- THEN all other participants see the new waypoint and recomputed route via Yjs sync
