# DBG-04 failure-timeline reproduction

This synthetic fixture checks whether three failure theories can produce a
supplied effect vector under one declared synchronous flow.

Run:

```sh
./run.sh
```

The fixture verifies logical compatibility only. It does not reproduce the
private request, establish timestamps, or model queues, retries, webhooks,
caches, transactions, or remote systems.
