What's included

What the plan specifies

• Range and format checks for every applicable field, defined against protocol-permitted values
• Cross-form and cross-visit consistency rules, including date-logic and dependent-field checks
• Required-field and missing-data logic, including how "not done" and "not applicable" are handled
• Severity and query-text conventions for each check, so programming and site-facing messaging stay consistent
• A clear boundary between what's built as an edit check versus what's covered by the Data Review Plan's manual review
