ProteinLoop · verified circular food production

Protect every protein output in the loop

Aquaponics already links fish and plants. ProteinLoop makes its animal-protein outcome measurable and recoverable, then extends the loop to freshwater prawns, duckweed feed, and eggs.

In the remaining 3, every model proposal was blocked and the deterministic emergency policy recovered the loop. The application records which path won instead of presenting fallback output as model output.

Off-grid continuity

Keep the food control loop local

Monitoring, AI guidance, safety checks, and producer decisions can stay at the farm so food operations do not stop with an internet outage. Measured solar autonomy is the next deployment proof.

No Wi-Fi DECT NR+ private field link

PT-to-FT traffic stays local without Wi-Fi, a SIM, or cloud access.

 Physical radio proven
No cloud Self-hosted Gemma + local verifier

A separate edge computer keeps inference and deterministic safety on site.

 Local AI proven
No electrical grid Solar + battery edge power

The target power system removes grid dependence after an energy audit.

Physical DECT NR+ link

real radio capture

Latest read-only exchange from the two connected nRF9151 boards.

DECT NR+ is a private, non-cellular 5G field link. The PT tank node can reach the FT gateway locally; this hop does not need Wi-Fi, a SIM, or cloud access. A separate edge computer runs self-hosted Gemma and the deterministic verifier.
