Context
The docs pages carried dates, but none said who keeps it true or when it was last checked.
Decision
Docs front matter gains owner, reviewed, review_by and type (Diátaxis). The 50 hand-written pages carry all four, with the date each was written from its source as the first review and the next review 90 days later. Vault pages start as not reviewed.
Consequences
The first reviews fall due in January 2027, listed on Docs health. Whether the gate should block on a missing owner or a late review is an open decision with the gate owner. See Docs tree.
