Background: Papers 1–3 of the ABM Blueprint Research Series established SADA as a quantifiable neurobiological state (Paper 1), demonstrated its attentional consequences (Paper 2), and introduced a composite biomarker for measurement (Paper 3). The Imagination–PAG–ECS Axis model (Bust, 2026d) subsequently identified the transdiagnostic mechanism by which mental simulation drives the ECS–CCK balance in both pathogenic and therapeutic directions. What remains unaddressed is the intervention architecture: how to systematically tip this bidirectional axis toward the placebo (anandamide) arm and away from the nocebo (CCK) arm through targeted, sequenced protocols. Objective: This paper introduces the SADA Recalibration Protocol, a four-phase, profile-specific intervention framework designed to restore autonomic complexity in individuals presenting with Limbic Friction (SADA-Entropy Score 50–79) or SADA Onset (score 0–49). The protocol is organized around the Hardware-First Principle: bottom-up autonomic restoration must precede top-down cognitive integration. Methods: The protocol synthesizes evidence from HRV biofeedback research, endocannabinoid pharmacology, exercise neuroscience, somatic psychotherapy, sleep medicine, and interoceptive training into a unified four-phase intervention architecture. Each phase targets a specific level of the SADA hierarchy: Phase 1 (Autonomic Floor) restores ECS-PAG axis function through aerobic exercise, resonant frequency biofeedback, and vagal toning. Phase 2 (Neuroendocrine Normalization) addresses CAR dynamics through circadian re-entrainment and nocturnal safety signaling. Phase 3 (Somatic Integration) recalibrates interoceptive fidelity and completes thwarted motor patterns. Phase 4 (Cognitive Consolidation) enables narrative coherence work and relational re-engagement only after autonomic stabilization. Critically, each phase is differentiated by attachment profile: Architect (avoidant/dlPAG), Radar (anxious/lPAG), and Special Forces (disorganized/vlPAG oscillation). Results: The protocol generates specific, measurable endpoints for each phase, tracked via the SADA-Entropy Score domains. Entry and exit criteria are defined for phase transitions. Profile-specific Bookend Protocols (Entry and Maintenance) address the distinct failure modes that precipitate relapse in each attachment phenotype. Preliminary clinical observations across 15,000+ hours suggest that the hardware-first sequence produces autonomic improvements within 4–8 weeks, preceding subjective symptom relief by 2–4 weeks. Conclusions: The SADA Recalibration Protocol completes the translational pipeline from theory (Paper 1) through differential diagnosis (Paper 2) and measurement (Paper 3) to intervention. Its central claim is that attachment is not restored through insight but through the systematic reconstruction of the biological infrastructure that makes secure attachment metabolically possible.
