…lush interval Send the $flag_exposure event from get_experiment_flag only when the flag exists, is enabled and carries a variant, with the variant key as the event value; log the cause at debug level otherwise. Deduplicate equal exposure events buffered within one flush interval, keyed on feature name, identifier and value. beep boop

An exposure without an identifier cannot be reconciled with conversion events. track_exposure_event now skips these and logs a warning. beep boop

get_experiment_flag()now sends the exposure event only when the flag exists, is enabled and carries a variant, and the event value is always the variant key. Each skipped case logs its cause at debug level: feature not found, feature disabled, or no variant.The event processor now deduplicates equal exposure events buffered within one flush interval. Custom events are never deduplicated. Duplicates from a failed-flush requeue remain possible (fine because delivery is at-least-once).
