Description The Outlines of Sanity introduces Constraint Dynamics, a theoretical and computational framework for understanding mental stability, consciousness, and inference as physical processes governed by constraint. The central claim is that mental health is not best understood as stillness, symptom absence, or permanent calm. A stable mind is a bounded physical system capable of preserving or recovering self-coherence while embedded in space, time, body, energy, social relation, and environmental load. Constraint Dynamics proposes that coherent selfhood depends on the coupling of three primary stabilising functions: Λ — Spatial LatticeA constraint of orientation: the capacity to remain located across body, place, representation, concept, and world. Γ — Temporal StrobeA constraint of continuity: the capacity to preserve sequence, rhythm, memory, anticipation, and temporal order. Θ — Energetic AnchorA constraint of source and consequence: the capacity to distinguish internally generated from externally received states, and to regulate the energetic budget that gives action, error, and reality their felt weight. When Λ, Γ, and Θ remain sufficiently coupled, the system can support a fourth emergent property: M — the MirrorThe Mirror is the system’s recursive capacity to remain observable to itself. It is not treated as an independently controllable module, but as an order parameter of constraint coupling. In ordinary language, M corresponds to self-coherence: the felt capacity to remain oneself across change. The core claim of the framework is that mental stability is recoverable coherence under load. A stable mind is not a mind without perturbation. It is a mind that can move, bend, change state, grieve, imagine, sleep, wake, fear, love, and recover without losing its organising form. Mental distress is therefore modelled not as a single kind of failure, but as a family of phase patterns in which the constraints required for self-coherence become overloaded, rigid, uncoupled, distorted, or depleted. These mappings are presented as hypothesis-generating phase profiles, not as diagnostic biomarkers or fixed disorder essences. The minimal state model is: Sₜ = [Λₜ, Γₜ, Θₜ, Mₜ, Lₜ, Rₜ] where Λ represents orientation or spatial coherence; Γ represents rhythm or temporal binding; Θ represents source/energetic anchoring; M represents self-coherence or Mirror stability; L represents load; and R represents reserve. The core dynamic relation is: Mₜ₊₁ = f(Λₜ, Γₜ, Θₜ, Lₜ, Rₜ, Mₜ) Plainly stated: tomorrow’s self-coherence depends on today’s orientation, rhythm, source/energy anchoring, load, reserve, and current self-coherence. The primary empirical prediction is that daily measures of orientation, rhythm, source attribution, energetic regulation, load, and reserve should predict later self-coherence and symptom instability better than symptom measures alone. The framework is accompanied by a computational implementation in the Golem system, a constraint-native inference organism designed around structured memory, verification, energetic cost, temporal consolidation, contradiction handling, and silence as a valid output. Golem operationalises analogous variables: Λ as lattice coherence and structured claim geometry; Γ as temporal binding through dream cycles, revision, and re-verification; Θ as energetic anchoring through provenance, verification cost, queue pressure, and silence; and M as a Mirror-like order parameter of organismic coherence. This does not constitute clinical validation of human mental health. It is better understood as a computational existence proof: the core terms of Constraint Dynamics can be implemented, measured, perturbed, visualised, and used to regulate a live inference system. The clinical and human claims remain empirical targets requiring prospective validation. The paper proposes a first empirical test: a 30-day daily diary and wearable study measuring orientation, rhythm, source attribution, energetic regulation, self-coherence, load, reserve, and symptom intensity. The central question is whether these constraint variables improve prediction of next-day self-coherence or symptom worsening beyond prior symptoms, load, and reserve. This release should be read as a theoretical and computational research programme, not as a completed clinical theory. Constraint Dynamics does not claim that all mental illness can be reduced to a simple formula. It does not deny neurotransmitters, trauma, development, cognition, narrative, social determinants, or diagnostic heterogeneity. Rather, it proposes that these factors act on, and through, the physical constraints that allow a mind to remain coherent under load. The framework is intended to be falsifiable. If the predicted relations among orientation, rhythm, source/energy anchoring, load, reserve, self-coherence, and symptom instability do not appear in data, the theory should be revised or rejected. If supported, Constraint Dynamics offers a unified physical account of mental stability as adaptive constraint coherence under load. If unsupported, its predictions should fail clearly. This release is offered as a falsifiable theoretical and computational framework for future empirical work.
