AI output is not authority.
LLM output is a noisy measurement, not a final answer. Phionyx governs the space between model output and real action: safety gates, bounded decisions, audit trails, replayable runtime evidence.
Phionyx does not make the model deterministic. It makes the runtime evidence path deterministic.
What Phionyx is
Three pillars, one story.
Each does one job. Together they keep AI output accountable to evidence.
The engine
Bounded Authority
A deterministic runtime that puts gates between model output and action. The model stays probabilistic; the runtime evidence path — gates, state, audit — is reproducible.
How the runtime gates work →The discipline
Agentic Development
Self-governance: an AI agent's own “I fixed / I tested / this changed” self-claims and tool calls are bound into verifiable evidence chains, checked against the actual diff before they count.
See self-claims held to evidence →The protocol
AIREP
The AI Runtime Evidence Protocol: one signed, hash-chained record per AI runtime decision. Neutral, vendor- and model-independent, and scope-honest. Phionyx is its reference implementation.
What a record carries →What changes
The difference is what happens before action.
Without Phionyx
The model's suggestion can become the system's behaviour. No deterministic record of scope, safety, approval, or replay.
With Phionyx
Every transition passes verifiable gates and produces a replayable audit envelope. The model stays probabilistic; the path is reproducible.
