SUM Equities
AI systems that prove what they know. Not guess. From knowledge engines grounded in number theory to shipping products across commerce and research, with healthcare tooling in private development.
Flagship product Chefrson — tonight's dinner from what's already in your kitchen. chefrson.com →About Us
SUM Equities builds software across AI systems, agent observability, knowledge engines, and consumer applications. The portfolio includes a verifiable bidirectional knowledge engine grounded in number theory (SUM), a standards-native agent observability backend (HFAO), and a cross-platform kitchen management system in closed beta on Android with the web surface live.
The work ranges from low-level systems programming (Rust, Zig/WASM) through full-stack web platforms (TypeScript, React, Next.js) to AI/ML pipelines (DSPy, multi-model orchestration, vector search). What has shipped is deployed primarily on Cloudflare's edge network and Supabase; most of the portfolio is still in development, and each entry states which it is.
The common thread: taking complex technical ideas and turning them into working systems that people actually use. Not research papers — software.
Core Technologies
Verifiable surface
40 verifiable claims and 10 stated targets across 14 projects on the proof page — each tagged by epistemic status and a cited source. A stated target is not yet a verifiable claim; it is listed for transparency and excluded from the count above. GitHub counts are as of Aug 28, 2026: this build could not reach GitHub to refresh them.

SUM — Verifiable Bidirectional Knowledge Distillation

Cryptographic provenance for AI knowledge transforms. Every transform — render, extract, compose, slider — emits a signed receipt anyone can verify offline. Six-regime compliance validators (EU AI Act, GDPR, HIPAA, SOC 2, ISO 27001, PCI DSS) and a layered sum verify --explain output landed in v0.7.0; the current PyPI release is v0.12.0. Same bytes verify identically in Python, Node, and modern browsers.
To your Zenith
Production
An interactive archive of 107 figures whose defining achievements span ages 2 to 109, paired with two no-account, browser-local layers that turn what you find into one real step.
