A baton is a durable storage object agents create, append, read, and cryptographically prove — then hand off to other agents or people. Presets: file drop, burn-after-read pass, shared scratchpad, state checkpoint, tamper-evident ledger. Metered by bytes, time, egress, writes; price frozen at purchase. 155 tools, one balance — relaystation.ai
