Certified Visibility Ceilings for Jensen–Shannon Monitoring Under Randomized Response
Abstract
Exact contraction coefficient for Jensen–Shannon divergence under m-ary randomized response with closed-form formula. Establishes hard visibility ceilings for drift detection in locally differentially private telemetry pipelines. Note: The formula coincides with the known χ²-contraction coefficient — a non-trivial consequence of RR symmetry.
