Personal Persistence Architectures: LP Admissibility as the Structural Ground of Personal Persistence

This is the fourth paper of the La Profilée Domain Series. Following the Domain Principle (D012) and the physical, biological, and organizational foundations of Domains I–III, it specifies the bridge assumptions connecting LP structural variables to personal observables and derives the LP structural account of personal persistence architectures. Persons are the domain where LP's most fundamental distinction — between continuing to exist and continuing to be the same — carries its most direct human significance. The structural separation of Q1 (IR_person ≤ 1: the person can integrate their transformation load) from Q2 (δ_F_person ≤ δ_F_person*: the person remains the same person) is not a philosophical abstraction. It describes an experiential reality that clinical practice, developmental psychology, and first-person reflection all recognize: a person can continue to function while no longer being themselves. The personal bridge assumptions connect: Frame (F) to self-concept clarity, values architecture, and identity-constitutive commitments; Module (M) to cognitive flexibility, behavioral adaptability, and emotional processing capacity; Coupling (K) to values-to-action integration, self-regulatory fidelity, and coherence between identity and behavior; Transformation load (R) to psychological demands, role pressures, existential challenges, and environmental stressors. Six structural results are derived. Result I — Personal Coherence Zone: persons persist as themselves within their personal Coherence Zone. Result II — Burnout as IR Overload: burnout can be interpreted as IR_person > 1 driven by R explosion — where demands systematically exceed integration capacity. Result III — Depression as Integration Collapse: depression can be interpreted as IR_person > 1 driven by IK depletion — where integration capacity collapses below the level needed to process even moderate demands. Result IV — Trauma as Erosive Memory: psychological trauma is the personal domain instantiation of erosive structural memory (D008). Result V — Identity Crisis as Q1/Q2 Separation: a person can continue to exist and function while experiencing profound identity discontinuity — Q1 holds while Q2 fails. Result VI — Resilience as Structural Reserve: psychological resilience is personal E_res — the capacity to absorb transformation load without approaching the personal persistence boundary. Domain IV is the final Domain paper before the Subject Series. Q1 and Q2 apply to persons as LP-admissible systems. Q3–Q5 — the additional conditions required for self-modeling, subjective continuity, and consciousness — are the subject of the Subject Series.
