Cross-framework mappings
No cross-framework mapping is seeded for this control. That is stated rather than filled in: a mapping nobody authored is worse than a gap you can see.
In CMDash this control is a row with an owner, a status, uploaded evidence kept with its full history, and an export an assessor can read.
