The Price of Self-Calibration: Exact Evidence Budgets and Manufactured Blind Sets in Adaptive Monitoring

The paper derives precise cost formulas for self‑calibrating monitors that adjust thresholds online to maintain a specified long‑run false‑alarm rate under arbitrary drift. It shows that the guarantee is an accounting identity, independent of the monitored signal, and provides exact evidence identities for both step and ramp drift scenarios, as well as an exact law for the fluctuation of the certificate’s own alarm rate. Additionally, it proves that any monitor designed to tolerate a drift class is blind to all faults in the difference of that class, identifying the blind set for speed‑bounded drift classes and quantifying power outside this set with a sharp Gaussian projection bound.

ServeGuard: Verifiable, Bounded-Residual Confinement of Operator-Invisible Channels Without Revealing the Certified Read Factor

ServeGuard is a supply‑chain primitive that allows a publisher to ship a proof‑carrying adapter for an open‑weight language model, proving in zero‑knowledge that the adapter contains no hidden backdoor channel in the monitor’s blind subspace. The proof is inexpensive because it relies on a deterministic function of the public base model, and the served residual is the model’s own public floor. The system lets consumers or regulators verify the absence of this class of hidden channels without revealing the certified read factor or trusting the publisher.
