Poseidon.

Poseidon is the silicon-bound substrate beneath the Mickai cooperative. Where the Arbiter conducts the cognitive brains, Poseidon is the floor they stand on: an operator-personalised AI accelerator chip that binds the SIOS bundle to silicon, attests the host before any brain executes, migrates the audit chain when the SIOS moves across hosts, and bootstraps the distribution endpoint under operator control. The Sovereign AI SoC product line (patents 53, 54, 55, 57) opens at a £1,500 to £3,000 retail price point and is the first commercial chip purpose-built for a sovereign AI operating system. Five inversions distinguish Poseidon from prior secure-enclave designs: operator-as-root-of-trust, host attesting to the silicon, SIOS bundle resident on the chip, audit chain that persists across hosts, and operator-controlled distribution endpoint. The cognitive cooperative runs unmodified on Poseidon; what changes is that the silicon now belongs to the operator, the keys do not leave the operator's hardware, and every action the brains take is rooted in a chip the operator controls.

• 01Bind the SIOS bundle to operator-personalised silicon at manufacture
• 02Attest host integrity to the silicon before any brain executes
• 03Migrate the audit chain across hosts without loss of lineage (patent 55)
• 04Bootstrap distribution under an operator-controlled endpoint, not a vendor key (patent 57)
• 05Run the 26 specialist domain brains on hardware the operator owns
