//! LIVE READ-ONLY integration test harness.
//!
//! Drives the app's real HTTP stack against a real Proxmox cluster to verify
//! every read endpoint and cluster connectivity. All tests are `#[ignore]`d
//! and only run with `--ignored`; they read `LIVE_PVE_URL` / `LIVE_PVE_USER` /
//! `LIVE_PVE_PASS` from the environment and skip (with an explanation) when
//! `LIVE_PVE_PASS` is unset.
//!
//! HARD RULE: no state-changing HTTP request is ever issued against Proxmox.
//! The only non-GET request is the authentication handshake
//! `POST /api2/json/access/ticket`, which only issues a session ticket.
//!
//! The OS keyring is deliberately never touched: `set_session_ticket` injects
//! the password-mode session into the in-memory connection state, so
//! `login_with_password`/`connect` (which write to the keyring) are NOT used.
//!
//! Run with:
//!   TMPDIR=/home/user/.cache/clustri-build-tmp \
//!   LIVE_PVE_URL=https://10.0.0.22:8006 LIVE_PVE_USER=ro_opencode@pve \
//!   LIVE_PVE_PASS='...' \
//!   cargo test --test live -- --ignored --nocapture
