# Depth sweeps for Geometric Transformers

- **Registry ID:** `catagi-gt-scaling`
- **Book:** Categories for AGI
- **Documentation status:** `curation-required`
- **Experimental status:** descriptive finite depth sweeps
- **Canonical documentation URL:** https://categorical-ai.sridharmahadevan.com/experiments/catagi-gt-scaling

## Purpose

GT-Full and Pre-LN depth comparisons with commutator, task, and topological diagnostics.

## Book location

- Chapter 14: Depth Sweeps for Geometric Transformers

## Documented studies

- GT-Full depth sweep
- Pre-LN depth sweep
- Average-versus-accumulated obstruction audit

## 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.

## Start here

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 archived figures establish finite descriptive trends, not a fitted exponent, asymptotic scaling law, or GT-specific mechanism.

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.
