Coil a playbook

A Coil is a versioned trading playbook: an allocation core (weights in bps summing to exactly 10,000) plus a written thesis, risk fuses, triggers, and an execution mode. It compiles into artifacts — a runbook, an execution capsule, a receipt, a share card — instead of executing anything itself.

A fuse is a typed, checkable constraint: position caps, order-size caps, turnover limits, hard stops. Every compiled artifact carries the full fuse list, and an execution capsule refuses to compile without the five mandatory fuses.

paper_only (the default) simulates and analyzes — no capsule compiles at all. preview_only and human_confirm compile capsules whose orders exist only as previews until a human confirms. agentic_mcp_enabled compiles only after you explicitly acknowledge it, and you monitor and own every trade.

A capsule is a bounded instruction bundle you hand to your own agent running Robinhood's official Trading MCP in your own Agentic account. HISS compiles text and JSON — it holds no credentials, opens no broker connection, and never sends an order.

A receipt is a deterministic fingerprint of what was compiled: manifest hash, fuse checksum, execution mode, and a hard-typed liveOrderSent: false. Anyone with the Coil JSON can recompute and verify it — it is proof of workflow integrity, never a performance claim.
