Axis Validation

Verify that candidate dimensions are truly independent and meaningful.

Tool

vault_query_graph + vault_search

Protocol

1. For each pair of candidate dimensions, check: can one change without the other changing?
2. Search literature for examples where dimensions vary independently
3. If dimensions always co-vary, merge them into one
4. If a dimension has only 1 value in practice, it's not a useful dimension — remove it

HARD-GATE

Must test pairwise independence for all candidate dimensions.

Yield

Returns: { validated: string[], merged: string[], removed: string[] }
