# PRE-09 hidden-write reproduction

This deterministic JavaScript fixture models a factory and an in-memory
transaction ledger.

It executes:

- eager related-row creation despite final attribute overrides;
- lazy related-row defaults with and without overrides;
- an explicit detached state which writes no rows;
- an explicit persisted graph; and
- an unexpected factory write surviving rollback after a simulated implicit
  commit.

Run:

```sh
node experiment.mjs
```

The fixture does not run Laravel or MySQL. MySQL's real `TRUNCATE TABLE`
implicit-commit behavior is established by the official source cited in the
post. The transaction ledger only demonstrates the consequence of ending a
test transaction before its cleanup rollback.
