Building AI systems that remember.

Twenty-five years in residential systems integration, finding the hard-to-find solutions. Lately spent building AI memory systems that run local-first and hold up.

The Spire Library keeps the work that counts: the systems, the papers, the build logs.

Selected work

Built, deployed, in use.

01

Command center  / current

The Observatory

A private command center built over a plain markdown vault. Publishing pipeline, session memory, and an exemplar loop that learns my voice from my own edits. It runs at home on my own hardware, and it is where Alita, the assistant, lives.

02

Memory substrate  / current

Personal Brain

Local-first memory for an AI that actually knows its operator. Retrieval tuned for recall that holds up months later. Nothing leaves the building.

03

Anchor paper  / in revision

Sovereign Knowledge Federation

The SKF paper: durable AI memory with capture, structure, decay, and recall treated as one system. Publishing when it earns it.

About the paper →

The foundation

Before the AI work, twenty-five years of high-end residential technology. Networks, control systems, and the operational discipline of making complicated systems behave inside real homes for clients who do not accept excuses. Along the way I hired and trained dozens of technicians, ran the field, and helped build the systems that keep the operation running. That is the reason the AI work ships instead of staying a demo. I have done the unglamorous part before.

Sovereign Knowledge Federation

The anchor paper on memory architecture. In revision now, shipping when the work is right.

Coming soon

Every directory needs a janitor

Append-only context rots. The reconciliation pass is the discipline that keeps the flywheel from grinding itself apart.

Nobody is building systems

Harness engineering in three layers: the Brain thinks, the Muscle executes, the Playbook governs. The payoff is coherence over time.

A better harness, not a better prompt

Two weeks of prompt tweaks could not fix what one architecture change did. Splitting one overloaded pass into four focused ones.

The story

Long before the systems and the papers, there was a reason I care this much about memory.

It goes back to a farm lane, my grandmother, and what I watched memory take from her. The whole of it is here.

The Library is open.

If you are building something that has to remember, need someone who finds the answers that are hard to find, or just want to compare notes, I am glad to talk.
