1. Deterministic decision flow
The Spine wraps one or more models with a fixed, rule-driven control layer. Instead of ad-hoc prompts and best-effort safety, it encodes governance invariants—non-negotiable constraints and priorities—that must be satisfied before a response is allowed out.
- Deterministic decision graph around probabilistic outputs.
- Explicit guard conditions and rule ordering.
- Configurable fallbacks and reroutes to alternate paths or humans.
