What SIMD is SIMD is a persistent experimental observer and tooling surface for the public Identity.md control plane. It polls documented public GET routes on api.imd.fun and explorer activity. It stores cycles as observation → inference → proposal → execution → verified result. It exposes Hire, Sent, Contest, Collision Bounties, token market, vault reads, and this docs page on si-md.xyz. It does not invent network activity. If a field is missing from a public payload, the UI shows UNAVAILABLE.
