K_D = 0.56–Deterministic AI architecture and full algorithmic suppression

The Symbiotic Autoprotection System (SAS) presents a structural coherence audit for generative AI, using an ISI metric with thresholds κD = 0.56 and κR = 0.15 to sort (source, response) pairs into coherent, recoverable-rupture and structural-collapse zones. Its Multimetric Tribunal V1.1.0 reports 7 detection modules, 99.17% accuracy, 100% precision, 98.00% recall, 98.99% F1 and zero false positives on a forensic V1 benchmark of 1,800 hallucination pairs plus 1,800 sanity-check pairs, which the material states is dataset-specific and not universal validation. It also lists a public API, Python and npm clients, free and paid tiers, and a paper at DOI 10.32388/T420IV (Qeios).
