It specifies the invariants that must hold at execution time: deterministic behaviour, fail-closed enforcement, auditability, and replayability.</p> <p>ECL is not:</p> <ul> <li>a governance framework</li> <li>a policy system</li> <li>an agent architecture</li> <li>a product or service</li> </ul> <p>It does not define what decisions should be allowed.<br> It defines how execution decisions are enforced at runtime.</p> <p>The specification is intentionally implementation-agnostic and policy-agnostic. Different systems may realise the boundary differently, but the execution-time guarantees must hold.</p> <p>The standard is complete, stable, and frozen.<br> Implementations may now treat ECL as a required execution-time layer in compliant stacks.</p> <p>Specification and reference materials are available here:<br> 👉 <a href="https://github.com/Rick-Kirby/execution-control-layer" rel="noopener noreferrer">https://github.com/Rick-Kirby/execution-control-layer</a></p> architecture ai agents governance
