    Type Declaration

    • pre_tokens: number
    • Optionalpreserved_segment?: { anchor_uuid: UUID; head_uuid: UUID; tail_uuid: UUID }

      Relink info for messagesToKeep. Loaders splice the preserved segment at anchor_uuid (summary for suffix-preserving, boundary for prefix-preserving partial compact) so resume includes preserved content. Unset when compaction summarizes everything (no messagesToKeep).

    • trigger: "manual" | "auto"
    session_id: string
    subtype: "compact_boundary"
    type: "system"
    uuid: UUID
