  # Phase 1: Configuration tuning (ROLLBACK - DISABLED)
  use_arbitrum_optimized_timeouts: false   # DISABLED - Back to legacy 30s/60s
  use_dynamic_ttl: false                    # Static TTL for now, enable later

arbitrage_optimized:
  # CRITICAL: Tuned for Arbitrum's 250ms blocks (vs 12s Ethereum)

  opportunity_ttl: "15s"                    # CRITICAL FIX #7: 60 blocks @ 250ms (increased from 5s to allow more execution time)
  max_path_age: "20s"                       # CRITICAL FIX #7: 80 blocks @ 250ms (increased from 10s for orchestration buffer)
