Axis Validation
Verify that candidate dimensions are truly independent and meaningful.
Tool
vault_query_graph + vault_search
Protocol
- For each pair of candidate dimensions, check: can one change without the other changing?
- Search literature for examples where dimensions vary independently
- If dimensions always co-vary, merge them into one
- If a dimension has only 1 value in practice, it's not a useful dimension — remove it
