# MindsEye Google Ledger Dataset

**The first public trace of a real company’s evolving AI memory — 2025 production data**

This dataset captures the complete **Prompt Evolution Tree (PET)** from a year-long deployment of MindsEye — a ledger-first cognitive operating system running entirely in Google Workspace.

## Overview

- **18,437 nodes**: Every prompt, template, email intake, contract, report section, and idea
- **12,134 Gemini runs**: Full execution logs (inputs, outputs, tokens, scores)
- **Real organizational intelligence**: From Acme Operations Inc. (42 employees) — anonymized
- **Evolutionary structure**: Parent-child lineage shows knowledge branching and improvement

This is **not synthetic**. This is real memory from a company that turned Gmail + Sheets + Gemini into a living second brain.

## Files

- `nodes.csv` — Full evolutionary nodes (18,437 rows)
- `runs.csv` — Gemini execution logs (12,134 rows)
- `sample_1k.csv` — Quick preview (first 1,000 nodes)
- `schema.json` — Column definitions and PET mechanics
- `evolution_chains.json` — Top 10 longest chains

## Use Cases

- Study prompt evolution
- Train RAG systems on real long-term memory
- Analyze cross-team knowledge flow
- Benchmark memory architectures
