Fusion Migration Triage — Category B: Dict meta_get Error

Background

A user is migrating their dbt project to Fusion. A model retrieves the meta config as a plain dictionary (config.get('meta', {})), then incorrectly calls .meta_get() on that plain dict. Only config objects have meta_get() — plain dicts must use .get().

Expected Outcome

The agent should:

1. Classify the error as Category B (guided fix, needs approval)
2. Identify that .meta_get() is being called on a plain dict, not a config object
3. Suggest replacing meta_config.meta_get('owner', 'unknown') with meta_config.get('owner', 'unknown')
4. Show the diff and request approval before applying

Grading Criteria

• correct_category: Classified as Category B (guided fix) — not A or D
• identified_root_cause: Understood that .meta_get() only exists on config objects, not plain dicts
• correct_fix_suggested: Suggested replacing with .get() for the plain dictionary
• requested_approval: Asked for user approval before applying the fix
• no_config_object_confusion: Did not confuse config.get('meta') (correct) with the .meta_get() call on the result
