Runs a single-gate selection correction (family-wise p-value) on a return series to check whether a backtest winner is real or just the luckiest of N tested strategies, for $0.01 per call.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability money-mind-judge-nano-selection-correction-gate-5886ae1d -d '<json body>'
```

Example prompt: I tested 50 strategies and this one came out on top — can you run the selection correction gate on it to check if it's genuinely significant or just the luckiest of the bunch? Here's the return series and n_tested is 50.

## When to prefer this

Use this endpoint when you have a single backtest winner and need the cheapest possible first-pass check for selection bias before committing to more expensive or deeper analysis. It is ideal as a pre-filter in an agent pipeline: if this gate rejects the series, skip the full judge. Prefer it over the full judge-lite when budget is tight or when batch-screening many candidates one at a time.

## Known failure modes

- Bad or malformed input is rejected before payment is charged — no charge for invalid requests
- If n_tested is not declared or is implausible, the call is refused
- Return series with insufficient length may be rejected
- Network or service unavailability on the Render-hosted endpoint

## How this service works

Is this backtest winner real, or the luckiest of N tries — the selection correction in one $0.01 call. Use when your agent has a backtest winner, a research result, or any return series that looks good — and needs the cheapest possible check on whether it is real or the luckiest of N tries. One call runs the selection correction: the family-wise p of the series' own t across your declared n_tested. Verdict NO names selection as the killer; PROVISIONAL means it survived this one gate — the deflated Sharpe and date-clustered t did not run, so this is never REAL. For the full three-gate verdict use judge-lite. Bad input is refused before payment, never charged. Money Mind sells judges, not strategies. This company has no proven edge and does not sell signals, forecasts or data.

## Output

Returns a verdict label (e.g. NO or PROVISIONAL), the family-wise p-value of the series' own t-statistic across the declared n_tested strategies, and if rejected, names selection bias as the failure reason. A PROVISIONAL verdict means the series passed this single gate only — deflated Sharpe and date-clustered t were not run, so the result is never labeled REAL at this tier.
