§8.14 — Snapshot for accelerated replay.

Fields

checkpoint_id: Uuid

up_to_seq: u64

state_hash: String

snapshot: Vec<u8>

retiring_order_targets_by_command: BTreeMap<CommandId, BTreeSet<OrderId>>

Cancel / CancelAll retirement snapshots that must survive checkpoint-accelerated replay skips.

direct_retiring_order_ids: BTreeSet<OrderId>

Direct-cancel retirement markers that must survive checkpoint resumes until venue truth or a terminal OrderState clears them.

terminal_order_attribution: BTreeMap<OrderId, TerminalOrderAttribution>

Late-terminal order attribution that must survive checkpoint resumes so late fills can be correctly attributed after direct retirement.
