# Benchmark interfaces
The three interfaces represent the same broad behavioral tasks with different user-context representations.
## Direct
Direct provides behavioral history in `input_text`.
- Belief: prior market questions, choices, and position-derived confidence, followed by a target market.
- Trade: prior current-market and other-market trades plus the target decision context.
Belief Direct has train, validation, and test files. Trade Direct also has all three splits.
## Profile
Profile replaces or summarizes substantial behavior history with a generated wallet profile.
Belief profile rows add:
```text
profile_generator_model, generated_profile
```
Trade profile rows add:
```text
profile_generator_model, wallet_profile
```
The profile files identify the generator model at row level and store the generated representation alongside each model-ready instance.
Belief Profile has train, validation, and test files. Trade Profile releases validation and test benchmark files plus `profiles_test.jsonl`.
## Retrieval
Retrieval augments the prediction context with records from support wallets excluded from the fixed experiment-wallet set.
Belief retrieval rows add:
```text
retrieval_method, retrieved_support
```
The accompanying metadata specifies exact event-slug matching, strict historical filtering, same-wallet exclusion, and top-5 latest matches.
Trade retrieval rows add:
```text
retrieval_method, retrieved_market_traces
```
Trade Retrieval releases validation and test files. Individual rows expose the retrieval method and retrieved traces.
## Cross-interface alignment
Use `sample_id` to compare interfaces. For Belief, released Direct, Profile, and Retrieval split counts match.
