Proof: added persisted quote_lifecycle_stat_subjects snapshots, refreshed statistics from retained per-quote subjects, preserved completed/attributed execution evidence during lifecycle retention, and wired successful lifecycle evidence into the dashboard trade funnel; verified with targeted lifecycle/dashboard tests, full npm test, and operator dashboard bundle build.
Assumptions: detailed successful trade rows already deleted by prior retention cannot be reconstructed from aggregate rollups without faking quote-level settlement evidence; the new subject table starts preserving surviving and future quote evidence after deployment.
Still fake: fee-aware realized PnL and venue-native fill truth beyond retained settlement/inventory evidence remain out of scope; already-pruned detailed success rows remain unrecoverable.
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.
