Approval status

Which parts of this site are agreed, who approved them and when, and which are still draft. Use it to judge how much weight to put on a page.

Status Means
Endorsed Approved by the named board. Teams and suppliers can rely on it.
Draft Published so people can use and improve it, but not yet approved. Check with your solution design authority before relying on the detail.

Pages still in draft show a "Draft - to be confirmed" banner. Individual guardrails have their own status, shown under each guardrail and in the guardrail library.
