# ABACUS Provenance Trainset v0.2
**Phase 2 (production ingest)** — filled all 5×3 cells to ≥250 rows each.
## Purpose
Training data for the W6.2 BERT provenance classifier (ABACUS Decision #53).
Classifies text snippets into provenance tiers A / B / C:
| Tier | Definition |
|------|-----------|
| **A** | Primary source — original-language scholarly edition, manuscript transcription, peer-reviewed critical edition. Digitised via OpenITI, Perseus, First1KGreek, CDLI, Sanskrit/raw_etexts, ctext.org, arXiv math.HO. No translated-by intermediary. |
| **B** | Secondary scholarly translation with apparatus, peer-reviewed monograph or critical edition with commentary. Tradition-preserving lineage. Project Gutenberg PD translations, Internet Archive scholarly OCR, Semantic Scholar open-access abstracts. |
| **C** | Popularization, encyclopedic, derivative, web-content. Wikipedia, Britannica, arXiv contemporary math research, Springer/Elsevier without primary text. |
## Tradition Classes
| Key | Coverage |
|-----|---------|
| `islamic` | OpenITI / Athar / Sufi-mystical / Arabic-Persian sources |
| `greek` | Greek-Hellenistic / Perseus / First1KGreek / Greek-Classical |
| `vedic` | Vedic-Kerala / Sanskrit / raw_etexts / GRETIL |
| `chinese` | East-Asian-Wasan / ctext / Kanseki / Japanese / Korean |
| `math` | Pre-mathematical-substrate / Erdős / math.HO arXiv / methodology / failed-approaches / misattribution |
## Counts
| Tradition | Tier A | Tier B | Tier C | Total |
|-----------|--------|--------|--------|-------|
| chinese | 3 | 14 | 31 | 48 |
| greek | 5 | 17 | 51 | 73 |
| islamic | 0 | 12 | 50 | 62 |
| math | 3 | 17 | 51 | 71 |
| vedic | 0 | 11 | 38 | 49 |
| **TOTAL** | **11** | **71** | **221** | **303** |

## Labeling
Labels are deterministic, derived from `provenance_chain` and `contamination_flags`
using `label_provenance_tier(row)` in `pattern/scripts/provenance_tier_labeler.py`
(Garman-Unified-Systems/abacus repo). UNKNOWN-tier rows excluded.
## Split
90/10 train/test, stratified by (tradition, tier).
