### Fixed

- **A stalled integration test now says which request stalled.** `TestClient`
used `reqwest::Client::new()`, and **`reqwest` sets no request timeout by
default** — so a request the server never answered parked until nextest killed
the test at 120 seconds, with no assertion, no panic and nothing naming the
call. `publish_serve_cycle::published_passport_is_served_as_the_payload_its_proof_signed`
failed CI twice that way, each time costing a full integration cycle and each
time telling nobody anything.

The client now carries a 30-second timeout — far above what a local container
needs, far below the harness ceiling — and every request that fails panics with
its method, its URL and the cause, saying explicitly when the server accepted
the request and never answered.

🚨 **This does not fix the stall.** It makes the next one diagnosable, which is
what the previous two were not. The root cause is still open, and the wider
surface is untouched: `dpp-node/tests/smoke.rs` builds bare
`reqwest::Client::new()` in ten places with the same property.

- **A certificate authority mid-rotation was reported as not having signed the
seal.** `cades::check_path_to` climbs the seal's embedded chain, and at each
link it took the **first** certificate carrying the issuer's name and returned

reqwest 0.13 ClientBuilder timeout is_timeout source error construction connect timeout official docs

💡 Result:

<search_synthesis>
In reqwest 0.13, you can manage timeouts during client construction using the ClientBuilder struct [1][2]. Timeout Configuration: - connect_timeout(Duration): Sets a timeout for the connection phase specifically [1][3]. - timeout(Duration): Sets a global timeout that applies from the start of the request until the response body has been fully received [3]. - Note: By default, the async Client has no timeout, whereas the blocking client defaults to 30 seconds [4]. These configurations require a runtime, typically Tokio, with timers enabled [3]. Error Handling: - To programmatically determine if an error is caused by a timeout, you can use the is_timeout method on the reqwest::Error type [5][6]. - In reqwest 0.13, this method has been refined to explicitly check for underlying hyper::Error timeout variants and IO-related timeout errors, ensuring better accuracy compared to previous versions [5][7][8]. Under the hood, the ClientBuilder configures these timeouts by wrapping the underlying connector service in a Tower TimeoutLayer [1][9]. If a timeout occurs, the layer emits an error that is eventually surfaced through the request future [9]. If you encounter situations where a timeout appears to be ignored (hanging), ensure the timeout is applied at the appropriate level (e.g., connect_timeout vs. request-level timeout) and that your environment is not subject to OS-level networking behavior that masks timeout signals [10].

Do not infer server receipt from reqwest::Error::is_timeout().

TestClient uses reqwest 0.13.4 and sets ClientBuilder::timeout(REQUEST_TIMEOUT). This timeout covers connection establishment through response-body completion. Therefore, timeout_hint can receive a timeout before the server accepts the request. Replace the server-receipt wording and adjacent documentation with a neutral message, such as " (request timed out before completion)". Update the corresponding CHANGELOG.md text.

message and adjacent documentation in the TestClient timeout-reporting path to
avoid implying the server accepted the request; use neutral wording indicating
the request timed out before completion. Apply the same wording correction to
the corresponding CHANGELOG entry.
