Corrections policy
Errors are corrected visibly, not buried
Accuracy takes precedence over preserving a previous conclusion. Price changes are normal updates; factual and calculation errors are corrections.
Correction classes
Material errors include wrong prices, arithmetic, plan identity, policy interpretation, source attribution or a conclusion based on an invalid assumption.
What changes on the page
Correct the fact promptly, update affected calculations and conclusions, and add a concise correction note with date when the error was material.
What is not erased
A past price that was correct on its observation date remains historical evidence. A renamed or changed product begins a new comparable record.
