What is due for re-checking
Every page has a review interval set by how fast its subject moves — 30 days for models, 45 for plans, 60 for products and the agent stack, 180 for policy. Keeping 107 pages current on those intervals costs about 13 pages a week, indefinitely. Published openly, because a reference that hides its own staleness is worse than one that admits it.
