Reality Mechanics: The Structural Conditions for Identity Persistence

Reality Mechanics defines the structural conditions under which identity persists within relational configuration. It begins from a single primitive — relation — and derives structure through an invariant dependency sequence: Relation → Asymmetry → Difference → Boundary → Strain → Identity → Bearing → Information This sequence defines dependency, not temporal or process-based order. No term may define, replace, or bypass a prior term in the sequence. Reality Mechanics specifies no quantitative governance and no mechanism. This is not a limitation but the condition under which the same structural dependency holds across domains where quantitative and mechanical conditions differ. Compatibility content is always supplied by the relevant domain. The system is evaluated locally — at the boundary under evaluation — through a formal operator set (O1–O6) resolving Persistent, Strained, or Non-persistent outcomes. A complete Result Map, Evaluation Terms table, and closure rules govern representation, runtime, and cross-domain use. Version 7.1 is frozen. It extends v7.0 with the formal introduction of Contact as an evaluation distinction in RM_01, RM_03, and RM_05. Contact names local boundary encounter where relation remains present across separation without compatibility, admissibility, or carrying resolving. It does not introduce a term into the structural sequence, does not imply admissibility or bearing, and is distinguished from Exposure in RM_03. Corresponding closure protections are added in RM_05. The dependency order and governing condition are unchanged from v7.0.
