The Sigma Runtime Documentation (SRD) provides the human-readable foundation of the
Sigma Runtime Standard (SRS) — a coherent framework describing attractor-based cognition,
recursive coherence mechanisms, and runtime safety architectures within LLM-mediated cognitive systems.
SRD serves as the interpretive and educational layer of the Sigma Runtime Standard.
While SRS defines canonical mechanisms and technical invariants, SRD focuses on:
It bridges the gap between formal specification (SRS) and operational practice (Runtime implementation).
The SRD set includes several key sections:
| Section | Description |
|---|---|
| Overview | Conceptual introduction to Sigma Runtime and its role within Sigma Stratum. |
| Architecture | Describes the layered runtime design (SL0–SL6) and cognitive field integration. |
| Runtime Loop | Defines the recursive control cycle (RCL), drift management, and coherence maintenance. |
| Memory | Outlines persistent, semantic, and symbolic memory systems. |
| Attractors | Explains attractor formation, classification, and transition protocols. |
| Metrics | Provides quantitative indices (Drift, Density, Coherence). |
| Failsafe | Documents the Fail-Safe Envelope and AEGIDA integration. |
Each section corresponds to a dedicated document within the /srd/ directory and follows
the standard header template from /templates/LICENSE-HEADER.md.
The SRS defines the normative runtime architecture, safety principles, and canonical terminology.
The SRD documents interpret these specifications for developers, researchers, and governance bodies.
The SSRG (Sigma Stratum Research Group) maintains both the SRD and SRS,
oversees SRIP proposals, and ensures consistency across the Sigma ecosystem.
SRD documents are maintained through the Sigma Runtime Improvement Proposal (SRIP) process.
Each revision is peer-reviewed by SSRG maintainers and merged after validation against the canonical SRS.
