# Splits and support pools

## Belief splits

`dataset/Belief/splits/split_config_v1.json` records:

- 2,000 experiment wallets;
- seed `20260318`;
- ratios 70% train, 15% validation, 15% test;
- ordering keys `stance_first_block`, `stance_last_block`, `market_id`;
- rolling history during split construction;
- at most 30 history items in prompts.

Counts are 98,094 train, 21,147 validation, and 22,204 test rows. Each split contains all 2,000 experiment wallets.


## Trade splits

Structured Trade counts are 1,311,941 train, 114,471 validation, and 59,560 test rows, with a fixed 2,000-wallet list.

## Support pools

- all wallets except the experiment 2,000;
- 29,319 support wallets;
- 1,669,164 support rows;

3. same-wallet exclusion;
4. five latest eligible records.

### Trade

Trade support metadata states:

- all wallets except the fixed 2,000 experiment wallets;
- 11,676 support wallets;
- 5,086,400 trades;
- sorting by wallet, block, and log index.

The released benchmark rows include `retrieval_method` and `retrieved_market_traces`.
