CPU time excludes database execution for SOQL and DML and excludes time waiting on callouts, so it will always be lower than wall-clock time and sometimes dramatically so." }, { "question": "Can I see this without a debug log?", "answer": "Not per namespace.

Cross-namespace attribution exists only in the log." }, { "question": "The block shows everything well under its ceiling, but the transaction still failed. Now what?", "answer": "Check that you are reading the last block rather than an inner one, and check whether the failure was a limit at all.
