//! End-to-end test for the global `[models]` defaults.
//!
//! Runs the built kigi binary against the mock inference server with a
//! caller-owned `$KIGI_SHARE_DIR` whose `config.toml` sets every global `[models]`
//! default. Asserts the turn succeeds with all of them set and that the
//! wire-observable one — `extra_headers` — reaches the `/v1/chat/completions`
//! request header, for a model with no per-model `[model.<id>]` override.
//!
//! The scalar defaults (temperature, top_p, max_completion_tokens, max_retries,
//! inference_idle_timeout_secs, stream_tool_calls) are exercised here to prove
//! they parse and the turn still completes; their resolution onto the model is
//! covered directly by `config.rs` unit tests. The headless turn does not
//! surface sampling params in the chat-completions body, so they are not
//! wire-asserted here.
//!
//! `#[ignore]` (needs a built binary). Run locally (auto-builds the pager):
//! ```bash
//! cargo test -p kigi-shell --test test_global_extra_headers_e2e -- --ignored
//! ```
