missing_value
A comparison was withheld because a value was missing
Both signals answered, but one of the two fields the comparison needs was null, so nothing was compared.
- appears in
- flag
- credits
- Free. The consistency analysis is arithmetic over answers already paid for and never costs a credit of its own.
What it means
A null field means not evaluated, never no. An invalid phone number carries no country, a reserved IP carries no location, and an address outside every installed register carries no mail-drop answer.
The comparison is reported with result `not_compared` so you can see it was considered rather than silently dropped.
What to do
Nothing to act on. Supply the missing signal, or read the per-signal block to see why the field was null.
