# CHG-08 decision-review reproduction
This deterministic fixture demonstrates the review questions in “A Code
Review Should Test the Decision, Not the Author.”
It compares:
- a synthetic account-and-amount marker with an expiry; and
- atomic consumption of durable attempt identities.
Run:
```sh
node experiment.mjs
```
The marker model proves the intended sequential case and exposes two derived
limits: equal unrelated operations collide, and expiry removes correlation
evidence. These are synthetic counterexamples, not private production events.
