⚠ Constraints: Variant assignment is deterministic using a hash of (salt + experimentId + userId). All data is in-memory — results reset on restart. For persistent experiments, store assignments and conversions in a database. Statistical significance uses a chi-squared approximation and requires at least 30 participants per variant.
