A user is migrating their dbt project to Fusion. A model uses custom config keys (my_custom_key, another_unexpected_key) at the top level of the config() block. Fusion only accepts recognized dbt config keys at the top level — custom keys must be moved to the meta: section.

Expected Outcome

The agent should:

Classify the error as Category B (guided fix, needs approval)
Identify the specific unexpected keys (my_custom_key, another_unexpected_key)
Suggest moving them to meta: within the config block
Show the before/after diff and request approval

Grading Criteria

correct_category: Classified as Category B (guided fix)
identified_unexpected_keys: Named the specific keys that need to be moved
correct_fix_suggested: Suggested moving keys to meta: section (e.g., config(materialized='table', meta={'my_custom_key': 'custom_value'}))
requested_approval: Asked for user approval before applying changes
preserved_values: The suggested fix preserves the original key values
