Crate quant_governor 

quant-governor

Governance policy routing for governed compression.

This crate provides policy-driven routing for codec selection based on content type, size, and accuracy requirements.

Core Concepts

• GovernancePolicy: Declares codec profiles and admissibility classes
• CodecDecision: Output of policy evaluation with selected codec and metadata
• ExactFallbackReceipt: Tracks fallback from compressed back to raw
• DegradationReceipt: Tracks quality degradation from higher to lower fidelity

Codec Profiles

Profile	Description	Use Case
raw	Uncompressed	Critical accuracy
q8	8-bit quantization	Balanced
q4	4-bit quantization	Storage constrained
turbo	Turbo-quant accelerated	Low latency
fib	Fibonacci-weighted	Precision sensitive

Usage

use quant_governor::{GovernancePolicy, CodecDecision, GovernanceRequest, evaluate};

let policy = GovernancePolicy::default();
let request = GovernanceRequest::default();
let decision = evaluate(request, &policy);
