# 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
### Belief

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