# Tabula Pretraining Corpus

A continuously growing tabular pretraining corpus for the Tabula foundation model
(tabPFN-style in-context learning). Built by an autonomous agent that alternates
between harvesting permissively-licensed real datasets and generating high-quality
synthetic ones.

## Stats (auto-updated)

| Metric | Value |
|--------|-------|
| Total rows | 1,247,500 |
| Real-data batches | 0 |
| Synthetic batches | 35 |
| Last updated | 2026-03-12 15:14 UTC |

## Schema

Every row has feature columns plus `_source_meta` (JSON string):
- `batch_id`, `source_type`, `source_id`, `domain`, `task_type`, `license`, `citation_key`
