ORACLE ENGINE
Generates 4 random digit pairs, finds the closest pair by combined value, applies mod-9 difference analysis and parity checks to produce a deterministic YES / NO verdict.
DAC TRANSMITTER
Converts a digital value (1–9) to 8-bit analog voltage (Vref=5V, 255 steps). Optional Nyquist sampling at fs=18Hz generates a full sine-wave payload, transmitted to satellite via HTTP POST.
SIMPLE VIEWER
Visualises the oracle's inner workings: 9 shuffled arrays, birA/birB pair generation, EVET combination detection, and positional mod-9 formula breakdown (a, b, c, d).
