This post is a clarification, not an announcement.
The Execution Control Layer (ECL) is now fully formalised as an execution-time architectural standard for AI-driven systems.
ECL defines a non-bypassable control boundary at the point where AI reasoning transitions into real-world execution. It specifies the invariants that must hold at execution time: deterministic behaviour, fail-closed enforcement, auditability, and replayability.
ECL is not:
- a governance framework
- a policy system
- an agent architecture
- a product or service
It does not define what decisions should be allowed.
It defines how execution decisions are enforced at runtime.
The specification is intentionally implementation-agnostic and policy-agnostic. Different systems may realise the boundary differently, but the execution-time guarantees must hold.
The standard is complete, stable, and frozen.
Implementations may now treat ECL as a required execution-time layer in compliant stacks.
