## Wiremock Pattern Notes

The `fetch_issue_statuses` tests use `wiremock 0.6` with dynamic response handlers
via `respond_with(move |req: &wiremock::Request| { ... })`. This is the recommended
pattern for tests that need to return different responses per call (pagination,
adaptive page sizing).

Key patterns:
- **Sequential responses**: Use `AtomicUsize` counter in closure
- **Request inspection**: Parse `req.body` as JSON to check variables
- **LIFO mocking**: wiremock matches most-recently-mounted mock first
- **Up-to-n**: Use `.up_to_n_times(1)` for pagination page ordering

## Cargo.toml Addition

```toml
[dependencies]
httpdate = "1"  # For Retry-After HTTP-date parsing
```

This crate is already well-maintained, minimal, and does exactly one thing.
