Simulation · Scenario planning

Many Worlds

Plays a business decision out across hundreds of thousands of simulated futures, then tests every possible response against the same draws and recommends the one that holds up.

Five library scenarios with illustrative figures. Change any assumption in the side panel and it reruns in your browser.

Field guide · Physical AI and world models

Dead Reckoning

A world model is dead reckoning for machines. A small ship plans by imagining forty futures at every fix, then drifts on a current its model has never heard of.

Scroll to follow the vessel, then take the helm yourself. Best on a laptop.

Take the helm

Live model · Reinforcement fine-tuning

Rulebook

A customer reply policy written as checks a machine can run, then used as the reward to fine-tune a model. A small transformer learns it live in your browser tab.

Training starts by itself and runs for a few minutes. Larkfield, the retailer in the examples, is fictional.

Walk the Pakhuis

Walk through a seventeenth-century Amsterdam canal warehouse, built in simulation for a study of robots that count stock while a reviewer decides what reaches the record.

Best on a laptop. Click to enter, walk with W A S D and look around with the mouse. The study behind it is on the Pakhuis profile.

New in the lab

Lab tools, October 2026

Seven tools that came out of the research. Five are instruments you run on your own studies, logs and agents. Two let you explore the published numbers. Each one runs in your browser.

Instruments you run

Last updated Lab tool

Pre-Registration Desk

Freeze a study plan under a hash before you run it, then mark each result against the rule you wrote down.

Judge Calibrator

Run a model judge twice over the same items and get the noise band to print beside a judged score.

Delegation Ledger

Write down what each agent owes before it acts, then read only where that disagrees with what ran.

Audit Row Reader

Read decision-head audit logs as a trail in your browser, with rotated files checked as one series.

Charter Forge

Write a delegation charter for an AI agent, place it by judgement and irreversibility, and size its oversight against the lab’s published findings.

Oversight Simulator

One set of controls drives four published studies, and every curve is a number the lab has already printed.

Delegation Index, live

Thirty questions put your organisation on the five rulers of the Delegation Index, next to the Q3 2026 reading.

Instruments from the research

Work the published numbers yourself

Each instrument runs on the coefficients a campaign published, with every number listed underneath. Nothing is sent anywhere.

Instrument

SIGIL tier explorer

Pick an irreversibility tier and compare what blocking review and review with a liability ledger did to the value of oversight there, beside what the registered prediction said would happen.

Open the instrument

Instrument

Trial Balance budget curve

Set a reading budget and a diary length and read how many skipped steps each of four audits finds, then switch fault classes on and off to see what a full read of the diary finds and misses.

Separate applications & research systems

Systems in the workshop

Each profile explains what the system does, how mature it is, and what remains deliberately outside this public site.

System 01Private working prototype

Agent governance

AI Control Plane

A register and evidence layer for examining an enterprise portfolio of AI agents: who owns them, how far they act, and what supports the trust placed in them.

View project profile
System 02Completed research campaign

Enterprise ecosystem simulation

AGENESIS

An agent-based laboratory for exploring how different levels of AI participation interact with enterprise structure, market conditions and industry context.

View project profile
System 03Working local application

Supply-chain stress testing

SCENARIO-X Studio

An interactive workbench for designing multi-product supply-chain experiments and inspecting where average performance hides a weak tail.

View project profile
System 04Working research product

AI output assurance

Assay Bench

A workbench for measuring the quality and checking cost of AI outputs when there is no simple answer key.

View project profile
System 05Paper-only research prototype

Paper-trading research

Personal Quant Agent

A research system that scans public market data, tests a small strategy library, applies explicit risk controls and records simulated decisions in a paper portfolio.

System 06Working research product

Physical AI and oversight

Pakhuis

A seventeenth-century Amsterdam canal warehouse, built in simulation, where two robots count stock and a reviewer decides what reaches the record.

When watching every hour starts to pay

A pre-registered simulation held hourly monitoring of an agent fleet and six-hourly inspection to the same nominal reviewer budget, and found the budget at which hourly monitoring starts to catch faults.

Oversight & accountability

Medium + LinkedIn ↗

The Judge’s Mirror

A preregistered study of how often a model judge agrees with itself on 197 blind case files, and how far down one model family a judge stays usable.

The Open Decision Head: An Executive Briefing

A retrained open decision head beat both a rule table and the hosted service on 800 fresh cases, after a first version that did not.

The agentic enterprise

Medium ↗

A Trial Balance for Agent Omissions

Agent logs record what happened and have no row for what didn’t. A pre-registered test of commitment accounting, an obligation ledger reconciled against executed calls, for catching omissions in procurement-workflow traces.
