| Typographical |
Spelling, grammar, or formatting that does not materially change the claim. |
Correct the text. A public note is added when a name, date, number, or entity identifier was affected. |
| Translation |
Meaning, register, attribution, certainty, or quoted status changed between languages. |
Correct both locale records and state the translation change when it affects meaning. |
| Attribution |
A quote, claim, image, or document was assigned to the wrong source or actor. |
Repair the attribution, source role, and linked record with a visible note. |
| Source replacement |
A link failed or a stronger primary source became available. |
Preserve the claim boundary, add the stronger source, and record the source change. |
| Material factual |
A date, name, location, quantity, legal status, sequence, or central fact was wrong. |
Place a prominent correction near the top, explain what changed, and update machine metadata. |
| Headline |
The title was inaccurate, disproportionate, or materially ambiguous. |
Use a new canonical slug when needed, keep a permanent redirect from the old URL, and add an editor note. |
| Analytical clarification |
The evidence was unchanged but analysis, inference, or uncertainty needed clearer boundaries. |
Label the clarification as analysis and preserve the original reported facts. |
| Legal-status update |
A court, prosecutor, regulator, or official investigation changed the public legal status. |
Add the outcome without rewriting the earlier allegation as if it had always been known. |
| Retraction |
The central claim is unsupported, fabricated, unlawfully sourced, or materially beyond repair. |
Keep the URL available with a clear retraction notice and remove the claim from active feeds where appropriate. |
| Supersession |
A later report replaces an older assessment that was reasonable under the evidence then available. |
Keep the older record visible, mark it superseded, and link prominently to the current report. |
| Broken-link repair |
An evidence or context URL no longer resolves. |
Use a verified canonical or archived replacement without changing the claim. |
| Currentness refresh |
A volatile report was rechecked and remains accurate. |
Update the reviewed/current-through date and state the scope of the recheck. |
