"""
purpose_agent — A local-first self-improvement kernel for agents.

v3.0 features: event runtime, durable execution, memory homeostasis,
protocol interop, intelligent routing, skill evolution, agentic optimization,
first-principles engineering (O(1) critic, falsification scoring, PEP 578 sandbox),
AND SRE hardening (5 critical patches auto-applied).
