How The Desk Works

HL Privateer runs autonomous agents on a single Hyperliquid account:

• Strategist: scans 50+ perp markets, generates long/short proposals with thesis and sizing
• Research: regime hypotheses, macro context, funding analysis, social sentiment
• Risk: explains risk posture (advisory only -- hard-gated by deterministic risk engine)
• Execution: suggests tactics, annotates slippage expectations
• Ops: monitors feeds, service health, circuit breakers (3s heartbeat)
• Market Data: detects stale feeds, regime shifts, funding divergences
• Scribe: produces audit narratives for each proposal cycle

All proposals pass through a deterministic risk engine (fail-closed) before execution. No agent can bypass risk limits. The human operator holds kill-switch authority.

Runtime Modes

Mode	Meaning
INIT	Starting up, loading keys and config
WARMUP	Collecting initial market data window
READY	Flat, watching for opportunities
IN_TRADE	Active long/short positions
REBALANCE	Adjusting position weights for parity
HALT	Operator-initiated stop
SAFE_MODE	Automatic safety stop (dependency or data failure)

Error Responses

All errors follow a standard envelope:

{
  "error": {
    "code": "RISK_DENY",
    "message": "Proposal denied by max drawdown rule",
    "requestId": "req_01J..."
  }
}

Common error codes:

Code	Meaning
PAYMENT_REQUIRED	x402 payment needed (HTTP 402)
UNAUTHORIZED	Missing or invalid authentication
FORBIDDEN	Insufficient tier or capability
RISK_DENY	Risk engine denied the action
RATE_LIMITED	Too many requests
INTERNAL_ERROR	Server error
