# Systems

Architecture notes on the systems Brendon Garner builds: what each one is, and how it bounds its agents.

## Piper

Private independent project · Current

An agent runtime for live capital operations. A model may decide that a spend should happen; deterministic gates it cannot widen decide whether it may.

## Canopy

Designed and built end to end, KIKI World · 2022 to 2026

A multi-tenant agent operating system. Many specialized agents run against live tenant systems under one intelligence contract, one output contract, one review path, and one learned decision layer.

## Podium

Led product and engineering; built all agentic capabilities, KIKI World · 2022 to 2026

A multi-tenant commerce API that gives many applications one end-user principal, one checkout state machine, one seller primitive, and one payment envelope that both people and agents can present.

## Agent harness

Independent practice · Current

A repository-level operating system for coding agents. It makes the correct start, scope, proof, and record cheaper than the alternatives, and makes the alternatives fail.
