Distortion-Corrected Emotional Criticality: Observation limits, protected evidence and budgeted closed-loop recovery

An internally consistent report can conceal a dangerous state, while an integrity alarm can occur without task failure. This paper links distortion monitoring in the Affective Gain Module (AGM) to recoverable information and useful action. The six-channel quadratic score and capacity correction remain conditional models. Total variation bounds every detector's true-positive minus false-positive rate, and a protected-domain criterion states when task labels survive bounded corruption; both specialize standard results. In a synthetic test, a report-only residual detects incoherent alteration within ten steps in 99.4% of episodes. Coherent forgery has the clean report law by construction, with observed alarm rates of 27.3% versus 26.5%; a noisy protected reserve sensor yields 53.5% versus 25.3%. These samples do not establish empirical equivalence. In a finite reference with paid audit and repair, trusted operations add no certified coverage at the declared prices (536 of 640 cells): the common route's saved slot can fund recovery that offsets its higher work cost. They add 30 cells when each common-route operation costs one unit more, 54 without that route, and none where reports identify the regime. Legacy programs reproduce, but a no-event sentinel mislabels most forecast positives and neither archived channel ranking survives correction. The results establish conditional interfaces, not universal detection, affect-specific efficacy or deployed security. Note on Version 2.0. This version replaces Version 1 (May 2026; then subtitled "A Robustness Framework for Adversarial Governance Signals") and is a full rewrite (about 4,500 to 13,000 words). The six-channel quadratic score and capacity correction are retained as conditional models; detection limits, a protected-evidence criterion and a finite reference with paid audit and repair are added. The legacy programs reproduce, but a no-event sentinel mislabels most forecast positives and neither archived channel ranking survives correction. Files: the manuscript as PDF and a supplement archive (93 files) with the retained experiments and checks, the finite reference, independent audit outputs and the legacy programs. The Version 1 files remain available in the previous version of this record. Series. Paper D of the Affective Gain Module (AGM) programme. The integrative flagship, Affective Governance in Adaptive Systems, and the other companion papers (A to C, E and F) are archived separately. AI use disclosure.
