pub const VOLUME_DRIFT_REL: f64 = 1e-9;Expand description
Relative volume drift between two measurements of the same body that is
still the same answer: the case gate’s band between a replay and its
baseline (examples/case_replay.rs), and the perturbation rescue’s bar for
a rung against the exact lane’s inclusion–exclusion identity
(csg::boolean::perturbation_retry). One number, so the rescue can never
accept a body the gate would call a different one. It only absorbs
last-bit summation noise.
