EventCompaction

@Serializable

data class EventCompaction(val startTimestamp: Long, val endTimestamp: Long, val compactedContent: Content)

A record that a continuous range of session Events has been replaced by a single piece of compactedContent (typically a model-generated summary).

An EventCompaction is attached to a new Event via EventActions.compaction; the original events are left untouched. When the next LLM prompt is built, the contents processor uses the range to skip the covered events and inserts compactedContent in their place.
