Promote 'schema dimension' to the defined term in its two definitional homes (Entity Integrity section Schema dimensions; Read Diagrams section Dimensions and Underlined Names), then shorten to 'dimension' in-context. Canon already used 'Schema dimensions' as the section heading and 'lineage through schema dimensions' in prose — this makes the defined term consistent and disambiguates from array and data-warehouse 'dimension'. Headings/anchors unchanged. Note: read-diagrams cell source normalized to a single string by the notebook editor; llms-full.txt regenerates from source.

Promotes schema dimension to the defined term, then shortens to dimension in-context.
Why
dimensionis overloaded — data-warehouse dimension tables, OLAP cubes, and array/tensor dimensions (the type-system and npy pages already use "dimension" for array axes). Qualifying it as schema dimension on definition disambiguates cleanly. This isn't a new coinage: the Entity Integrity page already titles the section## Schema dimensionsand says "lineage through schema dimensions" — this just makes the defined term consistent with that.Changes (definitional homes only)
A **dimension** is…→A **schema dimension** — often shortened to *dimension* — is…Notes
llms-full.txtregenerates from source (not hand-edited here).sourcewas normalized to a single JSON string by the notebook editor (valid nbformat, identical rendering).
