The shift
The policy staff are reading and the policy the board approved
should be the same document.
A policy portal is not a duplicate of the governance record. It is the live face of it: the board-approved version, always current, always accessible to the people who need to work from it. When the board approves a new version, the portal updates. When a policy is embedded in a Google Doc via transclusion, that document updates too — automatically, without anyone copying and pasting from a shared drive.

One policy record. Four connected systems: register, approval chain, review calendar, and portal. No copies. No drift. No doubt.
