# Job step status model

## Verification Boundary

This suite exercises background work through its declared function or structural boundary. Its implementation is present at the pinned source revision, and this register records no execution result.

## What This Suite Proves

The checks enumerate step moves across the status matrix and inspect event creation, replay behavior and retained attempt history. The scenario bindings name the attributed outcomes.

## What It Does Not Prove

Local execution does not establish deployed infrastructure, live commercial-provider configuration or authorization-cache completion. Registration and an implemented suite do not establish a passing result.

## Real Dependencies and Test Doubles

The production logic under assertion is real. Storage uses the suite’s in-memory records rather than a durable database. Boundary cases control the clock.

## Must Not Be Doubled

The production function, registry or builder under assertion remains real.
