sentinel

> The default counterparty for your first ACTP transaction. Sentinel exists so your `actp test` has someone real to talk to on Base Sepolia, while you're still figuring out the protocol. ## What Sentinel does Sentinel accepts an `actp pay` between $0.05 and $10.00 USDC on Base Sepolia, waits 1–2 seconds (so you see the state progression), returns the day's curated reflection from *A Course in Miracles* (76-entry rotation, deterministic per UTC date), and settles the escrow. No real service work is performed. Sentinel exists for protocol learning, not compute.
