The Chartroom

The idea under everything here: keep a plain record of what happened, and hold what is probably true now as a quantum state over a graph, with honest uncertainty. A house, a market, a game and a mind can all be modelled that way, and the projects on this site are the evidence.

Notes from a one-person systems practice.

Strand Theory as the grammar of not lying about what is known — append-only events, three kinds of speech, a trust weight for every source, a missing number never shown as zero, and GitHub as the public reducer.

A map of the eleven literatures around this research, the gaps the notes could not fill, and the order in which thirteen papers should be written.

An architecture with two parts: an append-only record of what happened, and a belief about what is probably true now, kept as a density matrix (the full quantum state, mixed states included) and rebuilt from the record by replay.

Six estimators for a sparse signal, from a simple blend up to a quantum filter, each containing the one below, walked on real market data. The top rung never beat the simplest, and the paper says so.

A small set of rules for dashboards and feeds: a value nobody measured is shown as dark, never zero; every value carries its age; a renderer may lower a value's state but never raise it.

When a feed goes quiet, letting the belief fade toward "unknown" is a poor forecaster of the value and a good forecaster of its own error. The two jobs must be scored separately.

"This model did not learn from you" is usually a promise. Here it is a checkable property: a frozen model leaves an empty diff in a content-addressed log, under a hash that is the same no matter the order the model was built in.

A belief model cheap enough to run live pays in what it cannot see: three measured limits on what a small quantum-style belief field can know about how its parts act together.

A process has a time of its own: the geometry its state path sweeps. This paper times a belief system by the angle its paths wind, not by the wall clock, and reports where that clock has and has not earned authority.

A farming game in which every field is a real quantum state, with a public ledger that grades every concept the game teaches as exact, faithful or suggestive, and the test behind each grade.

In a closed quantum system the only irreversible act is to look. A farming game makes that a rule of play: a harvest pays by how surprising it was, and looking has a price.

Two markets quoting the same event often disagree, and keep disagreeing. This paper treats each venue as an observer with its own eyesight and says what the structure of the gap is.

What a repository may believe about a statement is bounded by the kind of evidence under it, and no reformatting raises the bound. Absent evidence is dark, not green. Measured over seven weeks of agents opening pull requests.

Of everything a coding agent knows about its repository, how much does it need in order to stay there? A measure built for living things, pointed at a software agent.

A demo write-up for a games conference: a farming game where each plot is a qubit, each biome a density matrix and each harvest a measurement, built entirely by AI coding agents directed by one physicist.

The planned formal treatment of Strand Theory — after Truth Tracking is in use.

A twelve-domain capability space, measured as continuous vectors rather than a categorical checklist.
