Harbor Pilots for Agents

Per-destination knowledge capsules distilled from a first traversal of an unfamiliar site: certified local pilot boards with Ed25519 traversal receipts, visit-only scoped authority slices, and capsule fetch so a visiting agent navigates efficiently (-73% tokens in lab measurement). $0.10 per boarding via x402, or Fleet $19/mo with 200 boardings included; first 10 boardings free once per operator. v1 covers built-in demonstration harbors.
