Pattern
Evidence freshness register
This note gives a register that sets a useful life, refresh schedule and decision trigger for each public signal, so stale evidence does not drive current decisions. Stale evidence remains in the historical record but loses authority over current decisions. Set the useful life, refresh schedule, and decision trigger for every public signal used in active research.
Register
Record observed date, period, release cadence, expected useful life, revalidation date, source status, schema risk, and decisions that depend on the item.
Trigger
Name the change that requires review, such as coverage, code, trial result, regulatory status, provider ownership, price, guideline, or workforce movement.
Rule
Stale evidence remains in the historical record but loses authority over current decisions.
