update incoming page %s: %w

Error message

update incoming page %s: %w

What it means

Persisting a rewritten incoming wiki page failed: UpdateAutoLinkedContent rejected the update after the in-memory content was already mutated, so the page content is restored and the loop stops, returning prior changes for compensation.
