# Proof of Cognition · playground

Draw a real challenge from the [BaudCoin](https://baud.cash) mining protocol, answer
it, and watch the **deterministic validator** grade your artifact — the same construction
and the same grading function the miners face.

No wallet, no chain, no tokens are involved. This is the scoring mechanism in isolation.

## How to use

1. **Draw challenge** — generates a multi-hop inference task from a closed-world fact
   graph, with sampled constraints (token ceiling, citation requirement, forbidden modes).
2. **Answer** with the final entity plus citation markers, e.g. `the euro [1][2]`.
3. **Submit** — the validator checks every constraint and returns a verdict.

If you fail, it tells you the **specific failing constraint** and you get another attempt.
That is the protocol's multi-pass system: three attempts at 1.00× / 0.75× / 0.50× credit,
so formatting slips cost less than reasoning failures.

## Why it is graded this way

A mining mechanism can only pay for work an independent party can re-check. Anything
scored by an LLM judge cannot be replayed and collapses into trusting the judge. So every
constraint here is machine checkable and every verdict is reproducible from
`(seed, index)`.
