course op• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)
• Call: import fullseye as fs; fs.ledger.course_loop_bend(radius=30.0, width=8.0, arc_pts=64) (to call the implementation directly, import drivecourse; drivecourse.course_loop_bend(radius=30.0, width=8.0, arc_pts=64); from the registry, opsdrive.get("course_loop_bend"))
Semicircle at the end of the loop course (turning 180° to the left): entry (0, 0, 0) → around the center (0, R) → exit (0, 2R, π). The polygon is the half annulus bounded by the outer arc (radius R + w/2) and the inner arc (R − w/2). Area = π R w (closed form); the polygon is smaller by the amount lost to approximating the arcs with polylines and converges as arc_pts increases. Standard (loop course): width 8 m or more, roughly oval.

Raises ValueError: R ≤ w/2(内側の弧が潰れる)、幅・半径が正でない、arc_pts が不正。
