bjorn3 says: > On errors we don't finalize the incr comp cache, but non-fatal diagnostics are cached afaik. Otherwise we would have to replay the query in question, which we may not be able to do if the query key is not reconstructible from the dep node fingerprint. So we must track these flags to avoid replaying incorrect diagnostics.
