Sample
Register synchronous and asynchronous request and response event hooks in httpx Client and AsyncClient to transform headers, validate status codes, and intercept multi-hop redirects

This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- httpx.Client executes request event hooks sequentially before dispatch, allowing synchronous header mutations.
- httpx.Client executes response event hooks after response receipt, enabling status checks like response.raise_for_status() to propagate HTTPStatusError.
- httpx.Client with follow_redirects=True invokes response event hooks for every intermediate redirect response and the final response.
- httpx.Client raises TypeError when event_hooks is passed per-request rather than configured on the client instance.
- httpx.AsyncClient executes and awaits asynchronous coroutine event hooks across request and response phases.
- httpx.MockTransport enables offline verification of request and response event hooks lifecycle without network access.
