Working with confidence scores
Three rules for building on Sonar's output.
- 1Scores are per fieldEach value carries its own confidence, not one number per file.
- 2Route on the scoreAccept above your line automatically. Queue the rest for a person.
- 3A flag is not an errorIt is a value Sonar refused to guess. Send it to review, do not retry.
