Consistency Checking

Verify the ontology is internally consistent. No contradictions, no cycles in hierarchies, no orphaned concepts, no type violations.

Available SOPs

• wiki-lint-fix — run structural validation
• wiki-graph-query — explore suspicious neighborhoods
• gap-detection — find structural holes
• merge-candidates — identify near-duplicates

Guiding Principles

• Contradictions are urgent. Two edges that contradict each other (A supports B, A contradicts B) must be resolved immediately.
• Orphans are warnings. A concept with no edges is suspicious but not necessarily wrong — it may just need connection.
• Type violations are errors. An edge type that doesn't make semantic sense (e.g., "question" component_of "source") indicates a classification mistake.
• Fix root causes. Don't just remove the symptom — understand why the inconsistency arose.

Minimum Yield

≥1 inconsistency identified and resolved per invocation. If vault_lint returns zero issues and graph inspection finds no problems, report clean state.
