- evaluator: passes scenario.venue to matrix.record(venue=...)
- PerformanceMatrix.record(): accepts venue parameter (default='bingx')
- Enables cross-exchange learnings: same strategy tested on BingX vs Binance
gets separate performance entries per venue
Adversary ecology analysis:
Counterparties operate at ActionKind level (CROSS_SPREAD/PLACE/CANCEL),
not at order-type level. The CWM infers order type from ActionKind:
CROSS_SPREAD → fills aggressively → equivalent to MARKET
PLACE → passive quote → equivalent to LIMIT
This is correct and venue-independent. Fee calculation already uses
VenueRules (per-exchange fees). No adversary changes needed.
