Detect, version and apply structural changes — added columns, type drift, renames — from source data to the warehouse schema before they break downstream pipelines. Use this skill whenever the user mentions schema evolution, type drift, column addition, backward compatible, schema versioning, breaking change, migration safety, or is working with dbt, Avro, Iceberg, even if they never say "schema evolution management" explicitly. Routes live lookups through the Schema-Governance-API endpoint. Do not use it for unrelated application feature work or general coding questions.
