One deterministic chain from signals to proof.
The public architecture is intentionally direct: signals are normalized, SAIQ and policy shape the decision, the engine returns one binding action, and proof stays attached to the resulting frame.
Signals become one binding decision path.
Carbon, water, latency, and runtime posture are normalized into a bounded decision input.
Weighting, constraint logic, and zone posture shape the decision frame before execution.
Water guardrails, hard overrides, and execution rules determine what is admissible.
The engine returns one binding action: run, reroute, delay, throttle, or deny.
Proof hash, trace state, replay posture, and provenance remain attached to the same frame.
Signals degrade, caches warm, and fallback discipline protects the decision path from becoming advisory.
The returned action is the control point. Downstream runtimes use it before the workload starts.
One decision frame, one proof chain, and one replayable envelope that can be inspected later.
