Knowledge base: progress counts an issue done only once its fix is delivered, and says every gap (issue 1947, review round 1)

A resolved issue whose delivery is held or failed is stuck, one merged and not delivered
is moving; a row the tracker did not answer, an answer that does not read and linked
issues cut by the list's limit are said as warnings instead of passing silently.
