Where this sits with the other documents

• Security §11 — Documented limits. The authoritative statement of what is and is not restricted: egress is unrestricted for a run that does not opt in, which is every run in this fleet today. This document expands the paragraph; that one governs.
• Deployment postures — the capability row, and What we ask you to own.
• Concepts — where this sits among everything else in flight.

If any of them disagrees with this document, this document is the one to correct — but only after re-reading what actually ships, because the reason all four have been wrong about this control at least once is that its design changed underneath a promise.
