Reality Mechanics: Core Structural System

Reality Mechanics defines the core structural sequence of relational readability. Beginning from a single primitive — relation — the system derives structure through an invariant dependency sequence: Relation → Boundary → Availability → Strain → Bearing → Resolution The sequence specifies structural dependency order only. It does not supply temporal, causal, mechanical, observer, object, or ontological order as primitive. Each term depends on what precedes it; no downstream term retroactively becomes primitive. Reality Mechanics distinguishes three layers: primitive structure, structural availability, and application content. Primitive structure is supplied directly by the core sequence. Structural availability names downstream conditions obtainable where boundary conditions, strain, bearing, and resolution obtain. Application content supplies applied forms through which structural readability is expressed across domains. The core supplies the following dependency definitions: — Boundary: the structural conditioning through which availability becomes readable within relation. Not derived from relation by mechanism; not primitive over relation. — Availability: obtains under boundary conditions. Compatibility names availability; non-compatibility names its absence. Neither precedes boundary. — Strain: contrast under boundary. Force, pressure, motion, and mechanism are not primitive to strain. — Bearing: relations through which strain carries. Support, contact, agreement, and mechanism are not primitive to bearing. — Resolution: strain made structurally determinate through bearing. Resolution closes structural determination without terminating relational readability. Resolution makes five structural reads available: asymmetry (non-equivalent resolved availability), difference (distinct resolved availability), identity (resolved availability readable through boundary), information (resolved availability becoming readable at boundary), and system (resolved readability through the full sequence). These are downstream reads, not primitive terms. All further content — mechanisms, quantities, observers, values, causes, timelines, and domain-specific structures — is supplied by applications, not by the core. The core carries a Freeze Rule: the core is stable where revisions no longer alter the dependency order, primitive status, the definition of read, or the distinction between primitive structure, structural availability, and application content. Version 13.3 satisfies the Freeze Rule and is designated Core Frozen. Downstream development may proceed without reopening the core. The core sequence has been substantially revised from v7.1.
