# PFLT FSOT — sample densify + benchmark snapshot

**Version:** `0.2.0` (2026-07-21)  
**Companion model card:** [dappalumbo91/pflt-fsot](https://huggingface.co/dappalumbo91/pflt-fsot)  
**Code:** [protofluid-language-translator](https://github.com/dappalumbo91/protofluid-language-translator)

## Contents

| File | Role |
|------|------|
| `sample_densify.tsv` | Small form→gloss densify sample for demos |
| `metrics_snapshot.json` | Public catalog + MT benchmarks (sacreBLEU / chrF) |
| `DATASET_README.md` | This card |

## What this is **not**

- Not the full multi-GB densify/gold lexicon (local product only)  
- Not FLORES scores (Hub parquet still gated)  
- Not a claim of commercial DeepL news SOTA  

## Headline numbers (v0.2.0)
