Corrections, History & Retractions
Material changes are never hidden through silent editing.
Corrections are first-class public records.
Public notice
What was wrong, what is correct, why, source, reviewer and date
Version history
Published versions remain traceable with reasons for change
Outdated intelligence
Historical validity is separated from current applicability
Retraction
Issue → investigation → notice, while the original remains in audit history
Source health
Active, updated, changed, broken and archived sources trigger proportionate review
