                 if s.status == "OK" and 0 < s.value < 100]

Input: Multiple unreliable sensors + angry baby dragons
Process: 
1. Ignore readings during obvious tantrums (>1000% normal size)
2. Trust sensors that agree within 5% margin
3. Use backup tape measure when electronics fail
4. Account for wing position (extended vs folded)
Output: Best guess measurement with confidence interval

minimize: Σ(measurement_error²) + λ(sensor_reliability_penalty)
subject to: 
  - 0.5m ≤ wingspan ≤ 3.0m (biological constraints)
  - measurement_variance < σ_threshold
  - sensor_count ≥ 2 (redundancy requirement)

Solution: weighted_average = Σ(w_i × m_i) / Σ(w_i)
where w_i = reliability_score × (1 - age_penalty)

Thermal_Signature(dragon) = base_temperature + breath_intensity × excitement_level
Wing_Surface_Area ∝ heat_dissipation_rate ÷ ambient_temperature
Wingspan = √(Surface_Area ÷ aspect_ratio)

Account for:
- Metabolic scaling laws (higher metabolism = larger heat signature)
- Chemical composition of breath (methane vs hydrogen flames)
- Seasonal molt patterns affecting wing membrane thickness

LIDAR_correction = raw_reading × refractive_index_compensation
where refractive_index = f(temperature_gradient, humidity, magic_field_strength)

Doppler_shift_correction:
  f_observed = f_source × (c + v_wing) / (c + v_sensor)
  actual_distance = apparent_distance × (f_source / f_observed)

Multi-path_elimination:
  Use time-gating to separate direct returns from reflections
  Coherence_detection: discard signals with phase_correlation < 0.8
