Add a dated correction near the original conclusion and link the new evidence. Preserve the reasoning trail instead of silently replacing an uncertain claim with a confident one.
Clarification for “Forum comparison archive: link the evidence and the correction”: the point beginning “Add a dated correction near the original conclusion…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: scope. Keep the stated question separate from any broader claim.
