area_tolerance_ok(area_x: float, area_ref: float, rtol: float, radius: float = 1.0, atol: float | None = None) -> bool

Combined rel+abs area-agreement gate with a sliver floor (B.5 / §5.8.2).

|A_x − A_ref| ≤ atol + rtol·A_ref with atol ≈ 1e-15·R² the sliver floor: sub-atol areas are treated as equal-to-zero, so a “present-but-tiny” overlap and an “absent” one both pass. rtol is empirically calibrated per the loosest binding pair (GeometryOps-vs-S2); Python and Rust share the S2 core and agree far tighter. Pass an explicit atol to override the floor.

Rust

pub fn area_tolerance_ok(area_x: f64, area_ref: f64, rtol: f64, radius: f64) -> bool

The combined relative + absolute area-agreement gate with a sliver floor (B.5 / CONFORMANCE_SPEC.md §5.8.2):

|A_x − A_ref| ≤ atol + rtol·|A_ref|,   atol = 1e-15·radius²

Sub-atol areas are snapped to zero first, so a “present-but-tiny” overlap and an “absent” one both pass — the snapping / tie-break regime MUST NOT fail conformance (§5.8.2). rtol is empirically calibrated to the loosest binding pair (GeometryOps-vs-S2); Rust and Python share the S2 core and agree far tighter. This is the Rust analogue of Python geometry.area_tolerance_ok, the primitive that folds the Rust binding into the cross-binding tolerance gate.
