Precomputed tracker angle table: duplicate minute precedence · case 03

A corrected table entry appended later is ignored.

Member previewVariant 3 · 3 implementations · 7 checks per implementation

Case contract

table lists [minute, angle] entries in any order; for duplicate minutes the last listed entry wins. Outside [first, last] minute the tracker is flat (0.0). Inside, the angle is linearly interpolated between neighbouring entries and rounded to 2. Return the angle.

Why this case matters

Single-axis and dual-axis solar trackers turn a sun direction into actuator commands; a sign, frame or limit mistake points a whole plant away from the sun or into a mechanical stop.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
