Checks classify the current execution result. The card below reflects condition resolution, ordered keychain matching, and the failure-stop behavior implemented by the engine.
Key Check
The first matching non-empty keychain determines the resulting status.

Local reference · no request sent
Ordered keychains; each has result, conditions, and mode AND / OR
Condition: source, comparison, value
Comparisons: contains, not contains, equal, not equal, regex, greater/less than, exists/not exists
stop_on_fail
Evaluates keychains in order and assigns the first matching result.
AND requires every condition; OR requires any condition. Empty chains are skipped.
stop_on_fail halts the current data entry only when this block assigns Fail.
