property CoreModel.matrices

Scenario mappings with canonical keys and current-alias lookup.

Scenario mappings always store canonical matrix identifiers, regardless of active nomenclature settings. For example, after configuring E as R, both db.matrices["baseline"]["E"] and db.matrices["baseline"]["R"] access the same block, while iterating over the mapping yields E.

Assigning a block or a scenario also normalizes current aliases. Use query or get_data for calculated matrices and scenario comparisons; direct mapping access only retrieves blocks already materialized in storage.
