Corrections and Update Policy

If a note needs a factual correction, the note keeps its original stable slug, retains the original editorial publication date, and adds a visible updated date when the correction lands.

Material corrections stay on the same public URL so readers following an existing link continue to land on the current public record for that note.

Substantive note changes should be visible on the leaf in an update-history block. That block distinguishes between a correction and an analytical update instead of silently rewriting the public note body.

Minor formatting cleanup does not require a history entry, but any change that affects what a reader should understand from the note should be visible on the page.

If a note no longer reflects the available public record clearly enough, we may revise it, add a visible update, or stop presenting it as a current note.

Feed and news treatment can change over time, but the note page remains the place where readers can see the latest public version and any visible correction or update history.
