patent 0.7.0

//! Live smoke tests — the ONLY tests that hit real registry APIs.
//!
//! Every test here is `#[ignore]`d, so `cargo test` stays fully hermetic and
//! offline: the default suite exercises the adapters against `wiremock` canned
//! responses (see `tests/sources.rs`). These complement that with the one thing
//! mocks can't catch — an upstream API silently changing its response shape,
//! which would leave the mocked tests green while the real tool returns nothing.
//!
//! Run them explicitly (they need network, and are subject to upstream rate
//! limits and outages, so they are not part of PR CI):
//!
//! ```bash
//! cargo test --test live -- --ignored --nocapture
//! ```
//!
//! A nightly CI job (`.github/workflows/live.yml`) runs them on a schedule so
//! drift is surfaced as a failed run rather than a silent zero-results bug.
//!
//! Each query uses a deliberately popular, stable keyword for its ecosystem, so
//! an empty result set means the adapter can no longer parse the live response —
//! not that the query happened to match nothing.

// KNOWN BREAK — tracked for 0.7.1. PyPI has retired every keyless search path:
// the XML-RPC `search` endpoint is gone, and the web search page now sits behind a
// Fastly "Client Challenge" bot wall that serves a JS stub to any non-browser
// client (verified: identical challenge for a descriptive UA and a browser UA).
// So this smoke test fails by design today; the nightly workflow skips it with
// `--skip live_pypi`. It is kept rather than deleted so restoring PyPI in 0.7.1 is
// just: swap in a working backend, then drop the `--skip`. Until then the binary
// honestly surfaces PyPI as "not reached" at runtime — never as an empty result.
