Difference Taxonomy

Comparator 3.2 uses a structured taxonomy to explain why two outputs differ without changing Comparator v3.1 classifications.

Lexical Differences

• synonym_substitution
• phrase_rewording
• terminology_choice
• label_variation
• domain_vocabulary_substitution

Default significance: low.

Ordering Differences

• sequence_reordering
• edge_declaration_reordering
• list_order_variation
• narrative_order_variation

Comparator 3.2 distinguishes:

• order_invariant_presentation
• order_changes_execution
• order_unclear

Granularity Differences

• compressed_steps
• expanded_steps
• merged_steps
• split_steps
• pass_through_expansion
• abstraction_level_shift

Inclusion Differences

• omitted_step
• inserted_step
• omitted_transition
• inserted_transition
• omitted_condition
• inserted_condition
• omitted_ambiguity
• inserted_ambiguity

Structural Differences

• branch_added
• branch_removed
• loop_added
• loop_removed
• loop_target_changed
• merge_added
• merge_removed
• termination_added
• termination_removed
• terminal_path_changed
• entry_path_changed
• reachability_changed
• invented_edge
• missing_edge

Default significance ranges from medium to high depending on backbone impact.

Constraint Differences

• same_constraint_same_field
• same_constraint_different_field
• related_constraint
• contradictory_constraint
• threshold_difference
• stopping_rule_difference
• validity_rule_difference
• precondition_difference
• postcondition_difference

Recognition Differences

• explicit_recognition
• family_resemblance
• unknown
• not_recognized
• provider_style_difference
• recognition_without_structural_effect
• recognition_with_structural_import
• terminology_leakage_only

Representation Differences

• ast_present_vs_absent
• schema_completeness_difference
• summary_compression_difference

Semantic Role Differences

• same_role_different_label
• adjacent_role_substitution
• evaluate_vs_verify
• decide_vs_terminate
• generate_vs_prioritize
• observe_vs_interpret
• true_role_conflict
• unresolved_role_boundary

Evidence And Confidence Differences

• confidence_label_difference
