This read-only CucsFsmFlags bitmask carries internal attribute flags describing this task -- for example whether it's marked skippable, whether it ran, or other workflow-engine bookkeeping bits -- rather than a user-facing status. Engineers debugging why a workflow behaved unexpectedly (skipping a step it shouldn't have, or vice versa) look at these flags to understand the task engine's own reasoning, beyond what the completion field alone shows. A flag indicating the task was marked 'ignore' would explain why a step appears to have been silently bypassed during a firmware update.
