Detailed Description

Autonomous PT Calibration System
Automatically calibrates PT sensors by listening to raw UDP packets from the
DiabloAvionics boards and collecting calibration points at known reference pressures.

All board IPs, ports, sensor counts, and calibration paths are read from
config/config.toml via config_loader so you only change the config file.

Features:
- Reads raw board UDP packets (DiabloAvionics protocol) — no external dependencies
- Automatic calibration point collection with quality scoring
- Reference pressure input (from gauges, regulators, etc.)
- Automatic cubic polynomial fitting (psi = A·adc³ + B·adc² + C·adc + D)
- R² quality validation with confidence levels
- Automatic saving of calibration coefficients (JSON + CSV)
- Confidence-based autonomous operation
- Live ADC monitoring

_default_connectors()

The channels this board samples, from active_connectors.

That list is the config's only statement of which channels exist, and it need
not be contiguous — a board may declare {1, 2, 6} — so callers iterate it
rather than counting it.
