Each group combines its conditions and child groups using match: all (AND) by default, or any (OR). Values within one condition keep their existing semantics. At most 3 nested group levels below the root (root depth 0), 10 child groups per group, and 50 conditions across the entire tree. Each nonempty tags or excludeTags array, status, validationStatus, nonempty customFields key, fields entry, or activity entry counts as one condition; group containers do not count. Nested groups must contain a condition or a nonempty child group; the root may be empty. Campaign-specific activity requires all in its own group and every ancestor, but an any sibling is allowed. Send eligibility and project scope always apply outside these conditions.
