# Mean-field diagnostics for Geometric Transformers

- **Registry ID:** `catagi-gt-meanfield`
- **Book:** Categories for AGI
- **Documentation status:** `archived-artifact-only`
- **Experimental status:** archived single-seed pilot
- **Canonical documentation URL:** https://categorical-ai.sridharmahadevan.com/experiments/catagi-gt-meanfield

## Purpose

Local commutator-energy, normalization, transport, and task diagnostics for a data-limited prefix-to-suffix pilot.

## Book location

- Chapter 13: Mean-Field Theory of Geometric Transformers

## Documented studies

- Residual commutator diagnostic
- Pre-LN and GT prefix-to-suffix pilot
- Topological and Dirichlet diagnostic comparison

## Associated code packages

- `categories-gt-archive` — Geometric and Kan Extension Transformer archive; **local-not-public**; license decision pending. Working scripts and result directories for DB, GT, KET, language modeling, manifold, mean-field, and scaling studies. A curated public packet remains to be extracted.

These concrete files are selected from the complete resolved source surface. They orient the reader; they are not a claim that every family is independently reproducible.

## Frozen run records (0)

- No frozen run-level record is registered. Consult the result-artifact list and evidence boundary above for the exact surviving evidence; absence of a run record is not evidence that no experiment was run.

## Evidence boundary

The surviving plots and summary values do not include a complete executable snapshot or raw per-example outputs; the chapter treats them as archived pilot evidence only.

A code or artifact link establishes traceability. It does not by itself establish independent reproduction, statistical adequacy, correctness, or support for a claim beyond this boundary.
