Fixes #4761 `Table.update` does not compute embeddings, so changing an embedding source column could leave the previous embedding in place. Source-column updates now raise `ValueError` unless every associated vector column is supplied in the same call. The guard reads Python embedding metadata and native `lancedb::column_definitions` without loading embedding models. It uses Lance's field-path parser for quoted targets and covers synchronous and asynchronous local and remote tables. Supplying every associated vector column, vector-only updates, and unrelated updates remain supported. This is a breaking change for source-only updates. The API documentation and Update rows guide explain the requirement and the `merge_insert` alternative for regenerating embeddings. Validation at the reviewed head covered 44 targeted public update cases and the full Python suite (3107 passed, 162 skipped, 70 deselected). All applicable exact-head checks and workflows completed successfully.
