Fpt_kernel_daem_sqaw

A homeostatic Feedback Processor Theory (FPT) daemon that acts as a closed-loop dynamic controller for Admission Gate.

Architecture

The daemon operates as an async Unix domain socket server, continuously sampling telemetry from gated executions and modulating admission limits across multiple operational surfaces via a tuned PID controller with sigmoidal damping.

Running the Daemon

Requires admission-gate >= 0.4.0:

pip install admission-gate
python3 fpt_daemon.py &
Submit command proposals via the client:
