agentliveness 0.4.0

First public release.

Autonomous systems fail silently — fresh output over a dead engine. Predict less, detect more.

A small, dependency-free reliability harness for scheduled / autonomous agent systems. Four composing primitives, stdlib only:

• PersistentState — restart-safe atomic state that survives process death
• LivenessContract — prove a producer is producing, not merely fresh
• LoudFail — fire once per incident, never crash the run it protects
• agentliveness audit — static scan for the failure class, before it ships

pip install agentliveness

MIT · zero runtime dependencies · Python ≥ 3.9 · 26 tests including the flagship subprocess restart test.
