EDCA-OS (Expression-Driven Cognitive Architecture) is a newly released framework that proposes a protocol-governed, expression-driven approach for controlling LLM behavior.
The public v0.1 release includes:
• EDCA Protocol Stack (L0–L5) • Semantic Control Layer (public-safe) • Yuer DSL – a language designed for deterministic LLM execution • Behavioral Evidence Pack v1.0 • High-level architecture map (public)
It focuses on deterministic behavior, semantic-layer safety, and expression-to-protocol-to-behavior workflows.
No runtime implementations or proprietary logic are released. Only conceptual architecture and public-safe behavioral evidence.
