• Rows are explicitly marked Investigate when a pinned profile is missing or a score is nonnumeric, but the roll-up ignores those rows and passes as soon as any other row passes. This can report that protection is enabled despite incomplete evidence. When there are no failures, give Investigate precedence over Pass; N/A and Skipped controls can remain excluded.

• A single Pass row currently makes the whole assessment pass even when another pinned control is Investigate because its profile is missing or its score is nonnumeric. That can report protection as enabled without evaluating every applicable pinned control; handle Investigate rows before the pass branch while continuing to exclude N/A and Skipped rows.
