+"""Per-component performance attribution — rate each pipeline stage from the event stream.
+
+The owner's modularity ask: "isolate or add monitoring to specific components to rate or
+increase performance." Every stage already emits events (event-sourced architecture), so this
+derives a per-stage scorecard without touching the pipeline:
+
+  DISCOVERY  — symbols found/day, and what fraction ever produced a ready signal (precision)
+  SIGNALS    — ready signals/day, split EARLY (within the confirmation window) vs LATE
+  GATES      — what each entry gate cut (risk_rule_triggered histogram by rule_type)
+  EXECUTION  — approvals -> broker submissions -> fills; backout rate (entry efficiency)
+  OUTCOMES   — realized P&L, win rate, avg win/loss, trades/day (the only stage that pays)
+
+CLI:  python -m research.attribution [--days 14]
+API:  api/main.py serves compute_attribution() at /api/attribution for the dashboard.
+
+All queries filter on the native `timestamp` column first (payload_json casts on the full
+676k-row events table time out — learned the hard way)."""
