+#### Cross-Exchange Learning
+
+ScenarioFactory is venue-aware: `ScenarioFactory(exchange_id='bingx')` tags every
+scenario with its venue. Cross-exchange transfer re-tags for a different venue:
+```python
+factory = ScenarioFactory(exchange_id='bingx')
+scenarios_bingx = factory.build_suite(symbols=['BTCUSDT', 'ETHUSDT'])
+strategy = train(scenarios_bingx)  # evolve on BingX
+
+scenarios_binance = factory.cross_exchange_transfer(scenarios_bingx, 'binance')
+score = evaluate(strategy, scenarios_binance)  # test on Binance
+```
+
+PerformanceMatrix keys are `(regime, strategy_id, venue)`:
+- `get_best(regime, venue='bingx')` — per-venue best
+- `get_venue_comparison(regime, strategy_id)` — `{venue: score}`
+- `get_best(regime)` — venue-agnostic (backward compatible)
+
+#### Adversary Ecology
+
+Counterparties operate at the ActionKind level (CROSS_SPREAD, PLACE, CANCEL),
+not at order-type level. The CWM translates ActionKind to venue-native order types:
+- `CROSS_SPREAD` → fills aggressively → equivalent to MARKET
+- `PLACE` → passive quote → equivalent to LIMIT
+Fee calculation uses VenueRules (per-exchange fees). The ecology is venue-independent.
