WHY IT NEEDS A POLICY

Why collect_field_info needs a policy

This tool collects and stores user-provided field data into a form/database. It creates or modifies structured form records, which is a reversible write operation. It does not delete data or execute arbitrary code. Severity is medium because it writes user data to a database used in mediation/dispute resolution services, where incorrect or malicious data entry could affect legal/dispute outcomes.
