Observed history and review priority

Captured 8 Oct 23:13 UTC; extracted 16 Oct 16:10 UTC. Extractor: microsoft-1/9/fc65ebeb286710c0a830833db8a7e5de7e266b79981fe9c7c34479be9369ad3c/legacy.

Earlier unavailable versions and edits between checks are unknown. A missing statement requires review; it does not mean the policy was cancelled. Recovered historical statements are not original revision snapshots.
