Proof: DB-backed quote lifecycle retention policy, rollup-before-prune maintenance, dashboard storage visibility, and regression tests for preservation and fail-closed behavior. Assumptions: Completed quote outcome attribution remains the current durable successful-trade evidence; venue-native terminal fill ids and fee-complete PnL remain unavailable. Still fake: Historical non-success detail already pruned cannot be recovered; rollups are aggregate analytics, not per-quote settled trade proof.
