## Architecture

- Backbone: 6-layer Transformer
- Retrieval head: SPLADE sparse expansion
- Tokenizer: Morpheme tokenizer v4

## Files

| File | Description |
|---|---|
| mlm.pt | MLM pre-trained encoder |
| align.pt | Cross-lingual aligned encoder |
| finetune.pt | Fine-tuned retrieval encoder |

## Notes

This model replaces vanilla dense retrieval
with SPLADE sparse lexical expansion while
keeping the same Transformer backbone.
