A preflight is useful only when each output can be traced to confirmed facts, source references, and a mapping version. Missing information must remain visible instead of being filled by inference.
A practical preparation workflow
- 1
Select confirmed case facts and the mapping version.
- 2
Evaluate required fields deterministically.
- 3
Resolve issues with new evidence and rerun explicitly.
What to check
- Required field presence
- Conflicting confirmed facts
- Code confirmation needs
- Source and mapping version
