Boundary observatory
Pin two interval probes on the circle.
Interval A chordInterval B chord
Declared modelchord = 2R sin(delta / 2) | regulated length = 2 ln(chord / epsilon)
probe A
probe B
No external data is used.
Ask the boundary a better question.
Choose two endpoint-defined intervals and inspect the chords they draw through a declared disk model. The calculator keeps the cutoff visible so a diagram never masquerades as a universal distance.

Probe readout
Numbers and interpretation follow the model.
Calculate two probes to reveal their geometry.

Interpretation boundary. - The source's reconstruction idea is broader than this two-probe calculation; use this as an inspectable model, not as a physical measurement.
