ACGS-Lite: Constitutional Governance Membrane for Agent Execution

Headline: No valid receipt. No side effect.

acgs-lite is the constitutional governance membrane between agent reasoning and real-world execution. It is not an agent framework. Agent frameworks keep responsibility for planning, model calls, memory, and tool selection; acgs-lite decides whether a proposed side effect may run.

Core invariant:

No valid constitutional authorization, no side effect.
