Proof: Added PostgreSQL-backed quote lifecycle statistics for all-time, monthly, weekly, daily, hourly, and five-minute windows; wired authenticated dashboard API, live WebSocket counters, history-writer refresh before pruning, and dashboard controls; validated with targeted tests, full npm test, and operator dashboard build.
Assumptions: Unique quote counts are keyed by durable quote_id, quote windows use the first durable lifecycle timestamp in UTC with Monday UTC weeks, and missing identifiers or timestamps are represented as unavailable evidence instead of fabricated quote identities.
Still fake: Fee-aware PnL, cashflow, oracle-deviation, size distribution, matched-only analytics, and reconstruction of already-pruned detail remain outside this turn.
