The Mickai SIOS

Mickai is a Sovereign Intelligence Operating System (SIOS). It runs entirely on your own hardware, on Windows, Linux, or macOS. No cloud, no telemetry. This page describes one subsystem of the Mickai SIOS. Request a key to install on your hardware.

A subsystem of the Mickai SIOS. Long-term memory, vector store, RAG, persona persistence. Every memory committed via OAR.

Hippocampus. A subsystem of the Mickai Sovereign Intelligence Operating System.

The long-term memory subsystem rendered as an Olympian keeper of recall, a figure holding the thread of everything remembered against a void-black field.

Memory, kept sovereign

Nothing is forgotten without a signature.

Every recall, every persona partition, every write to the encrypted vector store carries an Open Audit Record envelope. Long-term memory you can interrogate, revoke, and prove, running on your own machine.

What Hippocampus remembers

Seven primitives that make long-term memory auditable. Encrypted vector store, semantic recall, persona partitions, signed writes, citation-grounded retrieval, on-device embedding, tombstone-and-revoke lifecycle.

01 / Function

Core function

The memory subsystem of the Mickai SIOS. Append-only, hash-linked, sovereign-stored episodic and semantic memory.

02 / Audit

Signed audit

Every state transition emits an Open Inter-Vendor Audit Record signed under FIPS 204 ML-DSA-65, walkable end to end by an offline verifier.

03 / Sovereignty

Operator-held keys

Cryptographic identity sits in TPM 2.0, secure enclave, or HSM controlled by the operator. The vendor cannot edit history.

Patent anchors

Hippocampus sits on three of the 101 filed UK patent applications behind the Mickai SIOS. Patent 05 anchors privacy-preserving RAG, patent 16 the signed write ledger, patent 18 the per-persona row-column ACL.

GB2607309.8 to GB2611702.8, GB2611885.1 onwards, and GB2612762.1 to GB2612793.6 · 101 filed UK patent applications · Approximately 2,234 claims

Wired with

  • ML-DSA-65 signed records (FIPS 204)
  • Open Audit Record (OAR) emit pipeline
  • TPM 2.0 / secure-enclave key custody
  • Trust-domain externalisation pattern
Read

Long-term memory, signed at the write.

Hippocampus persists across personas with a signed envelope on every commit. Read the privacy-preserving RAG patent, or request an access key and run a multi-persona memory partition on your machine.
