What qualifies
A record requires a specific public claim and a later action that materially conflicts with it. Both sides must be documented and independently reviewable.
Policy
Editorial policy
These operating rules are part of the public product—not an afterthought to the score.
What does not qualify
Ordinary evolution, changed conditions, ambiguous rhetoric, mere disagreement, and unsourced accusation do not automatically qualify as contradiction.
Corrections and response
Anyone may submit missing context or a correction. Editors record the resolution, preserve version history, and correct or retract material errors promptly.
For the full operational policy, see the corresponding repository documentation before enabling a public production environment.
