Purpose

Create traceable cleaned data and one reusable profile. Do not repeat the same data inspection separately for every candidate method.

Preconditions

• Problem parse and subquestion IDs exist.
• Raw files are available under workspace/data_raw/ or the workspace's documented legacy raw-data path.
• Required outputs and known field needs are available.

Stop rather than fabricate a missing attachment, unit, field meaning, or label.

Workflow

1. Map attachments before cleaning.
   • List each attachment with name, size, sheet names, headers, and a small preview.
   • Map it to Qx or mark it shared.
   • Ask the user only when two mappings remain materially plausible.
