Error message

list wiki page revisions: %w

What it means

Repository error in wikiPageService.ListRevisions: querying the stored historical snapshots for the page failed at the storage layer. The %w wraps the underlying database error so callers (revision-history handlers) can log/translate the real cause; it fires on DB failure, not on a missing page, which is checked separately.
