# PRE-08 ambient-clock reproduction
This deterministic JavaScript fixture models a mutable process clock and a
calculation which places a two-day-old record in a calendar month.
It executes:
- the same parameterless calculation under two process-clock values;
- a frozen clock leaking into a later test;
- guaranteed restoration after a synthetic assertion failure; and
- an explicit reference instant remaining stable after global state changes.
Run:
```sh
node experiment.mjs
```
The fixture does not run the private framework, repository, test suite, or
static-analysis rule. Dates and failures are synthetic. It proves the hidden
input and cleanup mechanisms, not a production incident or completed
explicit-clock migration.
