Shunyaya Symbolic Mathematical Hardware – Operational Playbooks: Payments, Satellite & Pilot Recipe (4.19–4.21)

4.19 — Payments & fraud ops (regime disagreement)

  • Scenario. Conflicting models thrash risk thresholds.
  • Inputs. Multiple model confidences on the same KPI (e.g., risk score) with alignments a_i.
  • Behavior. Combined lane exposes disagreement; values remain classical.
  • Week-1 pilot. Band rate-change logic on the combined lane; log reversals, do not alter limits.
  • KPIs & acceptance. Fewer false declines/approvals; reduced rollback volume.
  • Calculator-fast example (fused models).
    Given a = {+0.6, +0.3, -0.2}, equal weights →
    U := atanh(0.6) + atanh(0.3) + atanh(-0.2) ; W := 3 ; a_out := tanh(U / max(W, 1e-12)).

4.20 — Satellite ops (attitude determination)

  • Scenario. Star-tracker dropouts and sensor drift.
  • Inputs. Star tracker, gyro, sun-sensor alignments; attitude value is classical.
  • Behavior. Order-invariant fusion steadies attitude; bands guide momentum dumps.
  • Week-1 pilot. Publish attitude lane; apply advisory-only smoothing tuned by bands.
  • KPIs & acceptance. Smoother pointing; propellant savings.
  • Calculator-fast example (weighted).
    Let a_star = +0.8 (w=3), a_gyro = +0.4 (w=1), a_sun = +0.2 (w=1) →
    U := 3*atanh(0.8) + 1*atanh(0.4) + 1*atanh(0.2) ; W := 5 ; a_out := tanh(U / max(W, 1e-12)).

4.21 — The universal pilot recipe (copy once, use everywhere)

  1. Publish the lane next to 3–5 KPIs.
  2. Band & stamp. Show A++/A+/A0/A-/A--; stamp runs with knobs and checksums.
  3. A/B logs for 2–4 weeks; actuators unchanged.
  4. Compare waste/false alarms/oscillations/energy/time at equal classical outputs.
  5. Promote advisory gains; only then propose scoped closed-loop with a safety case.
  • Calculator-fast template (lane fuse).
    U := sum_i w_i*atanh(a_i) ; W := sum_i w_i ; a_out := tanh( U / max(W, 1e-12) ), with w_i := |m_i|^gamma (default gamma = 1).
