Struct SimulationCheckpoint 

pub struct SimulationCheckpoint {
    pub format_version: u32,
    pub journal_end: EvidenceCursor,
    pub state: SimulationSnapshot,
    pub archived_segment_headers: Vec<ArchivedSegmentHeader>,
    pub archived_segment_manifest_root: Option<String>,
    pub archived_evidence_receipts: Vec<ArchivedEvidenceReceipt>,
    pub archived_receipt_root: Option<String>,
    pub evidence_dependencies: Vec<EvidenceDependency>,
    pub evidence_dependency_root: Option<String>,
    pub keyed_draw_reservations: Vec<KeyedDrawReservation>,
    pub keyed_reservation_root: Option<String>,
}

Current authoritative state plus the journal cut required to validate it.

state deliberately contains empty append-only evidence arrays. It is not a standalone SimulationSnapshot; load it only with the contiguous evidence segments ending at journal_end.

Implementations

impl SimulationCheckpoint

pub fn reachable_archive_segment_ids( retained_checkpoints: &[Self], ) -> Result<BTreeSet<String>, CanwuError>

Returns every segment ID reachable from all retained checkpoint manifests.

Hosts must include every checkpoint they still promise to restore before treating a stored segment absent from this set as an orphan candidate.

pub fn orphaned_archive_segment_ids( retained_checkpoints: &[Self], stored_segment_ids: &[String], ) -> Result<Vec<String>, CanwuError>

Returns sorted stored segment IDs that no retained manifest can reach.

This method identifies host-GC candidates only; it never deletes content.
