What We're Building

We don't just advise on systems — we build and operate them. These are products under active development at Barnett Studios.

Meridian

Live

A multi-strategy, market-neutral crypto trading system. Two hedged strategies from day one — basis trading and perpetual funding — with unified circuit breakers protecting everything. Capital safety is the product; profit is a by-product.

Ink Abbey

Coming Soon

Your draft holds a masterwork; Ink Abbey is the editorial intelligence to find it. One manuscript, eight perspectives — structure, character, dialogue, theme, pacing, world, prose and style. They don’t write your book. They show you what isn’t working in it, and why. Manuscripts are encrypted at rest, with post-quantum cryptography readiness built in, so a novel written today stays safe in twenty years.

Open Source

An interface-bounded component family for agentic coding harnesses. Each is a standalone tool with its own contract, usable in any harness — not a plugin for a framework you have to adopt first. Together they form an architecture: context goes in, integrity is checked, evidence is kept, work is planned, and work is executed under isolation.

cxpak

↗

Context. Indexes a repo with tree-sitter across 43 languages and emits token-budgeted context bundles — a briefing packet instead of a flashlight in a dark room.

RustTree-sitterMCP

attestr

↗

Integrity. Promise-Theory verification — assesses a turn's output against the promises its agent declared, emitting findings plus a per-agent trust delta. Telemetry, never fed back into the live loop.

RustVerification

commitward

↗

Integrity. A deterministic, fail-open human-sign-off gate. Blocks a high-stakes commit only when a guarded change fires and nobody acknowledged it — everything else passes through.

RustHITLGit hook

corpus

↗

Evidence. 250 RED-baseline seed projects across six languages — with the validity census establishing which 230 actually function as a measurement instrument.

MeasurementMulti-language

abproof

↗

Evidence. Offline A/B change-validation for a whole harness — seed-blocked pairing, statistical gating, and an UNDERPOWERED verdict for a battery that could not have detected an effect.

RustStatistics

slicr

↗

Plan → execute seam. Decomposes a task into a granular execution manifest — single-region nodes, each with a discriminating acceptance test authored up front. The schema is the contract.

PythonPlanning

cascadr

↗

Executor: routing. A cost-ordered, fail-open provider cascade. Cheapest-capable rung first — and it never proxies a subscription hop, because that would break prompt-cache integrity.

RustRouting

cordon

↗

Executor: isolation. Runs one command in a hardened, ephemeral, network-isolated container, so a runaway process becomes a bounded, classified failure instead of a hang.
