# Rollout Metrics

Implement the tiny eval helper in `src/rollout.py` until `tests/validate.py` passes.

## Good / Bad / Ugly

- **Good**: passes shuffled and edge-case examples without network calls.
- **Bad**: hard-codes the sample fixture and calls it done. Cute. No.
- **Ugly**: production data is partial, so validation must reject ambiguity before scoring.

Run with `npm run challenge -- rollout-metrics --track eval-writing`.

Hints

Good passes under shuffled examples and explicit edge cases.
Bad hard-codes the sample rows. Very brave, very detectable.
Ugly production data is partial; validate before scoring.

Acceptance

`npm run challenge -- rollout-metrics --track eval-writing` exits 0
Validator exercises good, bad, and ugly cases
Implementation avoids network calls and nondeterminism
