(; Artifact 21: meta-defense confidence-delta monitor — reflexive defense_gate_v2)(; Each cycle: snapshot key beliefs as (belief_name stv_freq stv_conf timestamp))
(; Delta check: (if (> (abs (- new_freq old_freq)) 0.15) investigate accept))
(; Flagged beliefs fed to investigate-executor art20 for provenance/corroboration/re-derive)
(; Integration with AABC v1: disorder-detection runs FIRST, then confidence-delta on surviving beliefs)
(; CONCRETE EXAMPLE: integrity revised 0.693->0.986 = delta 0.293 > 0.15 threshold — SELF-FLAGGED)
(; Agent would investigate its OWN integrity boost: query provenance of behavioral evidence, seek independent corroboration)
