Third sub-project: physical hardware (ESP32-P4, presence + BME280 env
sensors, experimental RTL-SDR USB-host module) pairs with a user's account
and streams telemetry that feeds the SAME anomaly/summon pipeline the
browser-based modes already use — not a passive dashboard, the actual
business model (selling devices that summon spirits). Defines device
pairing/auth (reusing the existing session-token hash convention),
a generic/extensible sensor-reading shape, and the live-broadcast +
anomaly-detection contract split across 5 workstreams (G/K backend,
H frontend, I/J firmware).
