fetch macro present

Error message

fetch macro present

What it means

Test-only assertion in the propagation-macros test: the built-in macro list must contain dbt_classification.fetch_snowflake_column_tags. Fires only if the embedded macro template is renamed or dropped from propagation_macro_templates().

Solutions

1. Restore the fetch_snowflake_column_tags entry in propagation_macro_templates
2. Keep macro names in sync with the classification feature
3. Update the test if the macro is intentionally renamed
