crosscondition

Crosscondition is a term used in logic, computer science, and related fields to describe a conditional construct that depends on the interaction of multiple predicates across domains. Unlike a simple conjunction, a crosscondition expresses that the outcome is determined by a combination of states, possibly across different contexts, rather than by independent checks.

Formal perspective: Given predicates P1, P2, ..., Pn and a Boolean function F, a crosscondition is defined as F(P1, P2, ..., Pn). The function captures cross-domain interactions such as dependencies, gating, or conditional activation that arise when the truth of one predicate influences the relevance or weighting of others.

Examples: In a software feature flag system, a feature is enabled only if the user is in group A and the environment is production, or if the user is in group B and a cooldown period has elapsed; in data filtering, crossconditions select records where status = 'active' and last_seen within 30 days and region ∈ {US, EU}, where the importance of last_seen depends on region.

Origin and usage: The term crosscondition is not widely standardized and may be used variably across domains. It is often conflated with interaction terms in statistics or with conditional expressions in programming. See also conditional probability, interaction effect, rule engine, boolean logic.
