v0.3.16

What's New

arb exec — One-command dual-leg arbitrage

• perp --json arb exec <SYM> <longEx> <shortEx> <$> --leverage N --isolated
• Orderbook depth validation on both sides
• Lot size auto-rounding per exchange
• Simultaneous execution with auto-rollback on partial fill
• Post-execution position verification (detects HL silent rejects)

Portfolio includes risk assessment

• portfolio JSON now includes risk: { level, canTrade, violations[] }
• No need for separate risk status call — one command gives everything

arb scan optimization

• --top N option to limit results
• Trimmed JSON fields (removed per-exchange mark prices, individual rates)

Relaxed default risk limits

• Removed LIQUIDATION_DISTANCE_HARD_CAP entirely
• Defaults: 100K position, 500K exposure, 50x leverage, 95% margin util
• Agents manage risk via skill guidance, not code enforcement

SKILL.md updates

• Documented arb exec workflow
• Clarified portfolio includes risk data
• Position sizing and arb direction guidance
