Business Rules Reference
Rossum business-rules & validation reference — the two ways to validate extracted data and block automation: native Rossum Rules (the /v1/rules entity — trigger_condition + actions[], FIRE-vs-PASS polarity, lifecycle; the trigger_condition is written in TxScript, so for that syntax see txscript-reference) and the legacy Business Rules Validation Store extension (checks[] config, error/warning/info result types, automation blocking, queue scoping, one-rule-one-table limit, plus its own curly-brace expression engine — has_value({field}), aggregations, casting, similarity/substring/regexp — documented in full in this pack because it is specific to this extension). Use whenever the user works on business rules, validation rules, data validation, native Rules vs. the business-rules extension, blocking automation on invalid data, rule actions, the checks[] config, or gating on field values — even when they just say "add a rule" or "validate this field".
