Corrections
Change the conclusion without erasing the record.
ZAPHAN preserves original posture, subsequent evidence, evaluation, and material correction history.
What we correct
Material factual errors, source attribution errors, calculation errors, misleading omissions, and changes that alter a decision-relevant conclusion.
What remains visible
Where appropriate, the original publication, correction date, changed language, reason, and current evaluation remain traceable.
Working policy notice: response targets and formal intake procedures require final operational and legal review.
