Field geometry

12 specimens · 36 fields · 180 objects · um

specimen_equal · 95% pointwise percentile intervals · 2000 specimen-cluster replicates. Observed 2D geometry; synthetic data if using the bundled demo.

Intervals are approximate percentile bootstrap intervals, not guaranteed finite-sample coverage.
Sampling uncertainty excludes segmentation and calibration error.
Higher moments may be unstable; no finite-moment or tail adequacy claim is made.
Angular moments use deterministic quadrature; angular error is not a sampling CI.
Frame/complete-boundary sampling declarations are user assertions, not verified from images.
