This paper develops a constraint-based account of coherence signatures within operationally closed relational frames. Building on Closed Observational Relationalism (COR) and the Coherence-Only Signature Criterion (COSC), it shows that multiple non-local, scale-insensitive ordering patterns admissible under closure may be treated as orthogonal fragments (projections) of a single higher-scale invariant constraint. Apparent diversity across scales arises from directional access asymmetry and the fragmentation of invariant projection along emergent relational axes (reachability, incomparability, stability). These fragments lack internal causal grammar and cannot be causally reconnected within the frame. The framework introduces no new primitives or ontological commitments and operates strictly at the grammatical level of admissible description under closure and non-retraction.
