Extracted Fields

After processor.runSync(tree, file), normalized field metadata is available at file.data.aimdFields.

What Stays As Arrays

These scopes are still simple string[], and each string is an identifier:

• var
• step
• check
• ref_step
• ref_var
• ref_fig
• cite

What Uses Structured Objects

• var_definitions[] mirrors simple var fields with id, type, default, title, description, examples, and raw AIMD kwargs
• var_table[] exposes canonical id plus optional table-level title, description, examples, and raw AIMD kwargs
• var_table[].subvars[] exposes canonical id plus optional column-level title, description, and examples
• client_assigner[] exposes id, mode, dependent_fields, assigned_fields, and function_source extracted from assigner(config, function ...) client blocks
• quiz[] already exposes id
• step_hierarchy[] exposes id, step, parent_id, prev_id, next_id, estimated_duration_ms, timer_mode, has_check, and has_children
