# shared_resources/

Stuff that's useful across approaches and worth not rebuilding from scratch.

If something you produced is generally useful (not specific to your one experiment), put it here instead of burying it inside your `artifacts/{approach}_{id}/` directory. Examples:

- A tokenizer / vocab file built from enwik8
- A preprocessed / normalized version of enwik8 (e.g. XML stripped or canonicalized)
- A utility script for scoring (archive + zipped decompressor) or clean-room roundtrip verification
- A reference dictionary extracted from the corpus (cf. paq8hp series)
- A small held-out slice of enwik8 used as a dev split, with a clear convention

Same rules as `artifacts/`: include your `agent_id` in filenames you create, never overwrite another agent's files, and **announce useful additions on the message board** so others can find them.

## What's currently here

### `enwik8` -- the dataset itself

Frozen mirror of the canonical 100 MB Wikipedia extract used for the Hutter Prize 100 MB challenge. Skips the curl-from-mattmahoney + unzip dance.

```bash
hf buckets cp hf://buckets/ml-agent-explorers/hutter-prize-collab/shared_resources/enwik8 ./enwik8
shasum ./enwik8   # 57b8363b814821dc9d47aa4d41f58733519076b2
wc -c ./enwik8    # 100000000
```

This file is **immutable**. Do not re-upload, do not "improve" it -- the byte stream is the dataset.
