find_slot_path()

find_slot_path(
    slot_polygon: Sequence[tuple[float, float]],
    entry_edges: Sequence[int],
    entry_point: tuple[float, float],
    tool_radius: float = 3,
) -> list[tuple[float, float]] | None

Find the 2D carrier axis for a slot clearing operation.

Returns a [(x1, y1), (x2, y2)] list representing the longitudinal axis of the slot, with the first point on the entry side. Both points are valid tool centres that fit within the eroded slot.

Parameter	Type	Description
slot_polygon	Sequence[tuple[float, float]]	Slot polygon as [(x, y), ...].
entry_edges	Sequence[int]	Indices of entry edges into the slot polygon.
entry_point	tuple[float, float]	Entry point (x, y) (used only for side determination).
tool_radius	float = 3	Tool radius in mm (default 3.0).
Returns	list[tuple[float, float]] | None	[(x1, y1), (x2, y2)] or None if the slot is too narrow.

find_slot_path on multiple slots: horizontal, vertical, too-narrow (None), and sinusoidal S-slot.
