Pattern ID Name Description First Observed Experiments Typical Cause Backbone Impact Status
DPR-001 Lexical Equivalence With Stable Backbone Lexical phrasing changed while backbone remained stable. ECR-000003 EXP-001; EXP-002; EXP-003 lexical_variance none supported
DPR-002 Neutral Pass-Through Expansion A neutral intermediate step appears without backbone change. ECR-000003 EXP-001; EXP-002 elaboration elaboration_only supported
DPR-003 Constraint Concept Moved Across Fields The same constraint concept appears under different schema fields. ECR-000003 EXP-002; EXP-003 schema_placement none supported
DPR-004 Recognition Decay With Stable Extraction Recognition language changes while extracted structure remains stable. ECR-000003 EXP-001; EXP-003 provider_style none supported
DPR-005 Provider-Specific Granularity Providers vary in decomposition detail while retaining related roles. ECR-000003 EXP-001; EXP-002; EXP-003 provider_style localized supported
DPR-006 Domain Vocabulary Shift With Stable Topology Domain terms differ while topology remains stable. ECR-000003 EXP-003 domain_semantics none supported
DPR-007 Primitive Role Agreement With Sequence Disagreement Roles agree even where sequence order diverges. ECR-000003 EXP-001; EXP-003 compression localized supported
DPR-008 Explicit vs Implicit Loop Representation Loop behavior is expressed directly in one response and indirectly in another. ECR-000003 EXP-002; EXP-003 representation_format localized supported
DPR-009 Decide vs Terminate Boundary Decision and termination wording remain difficult to separate. ECR-000003 EXP-002; EXP-003 comparator_limit unknown supported
DPR-010 Evaluate vs Verify Boundary Evaluation and verification labels remain adjacent and sometimes unresolved. ECR-000003 EXP-001; EXP-003 comparator_limit unknown supported

Patterns are observational and not universal laws.
