//! p9-fb-32: CLI ask output — JSON path emits `indexed_at` + `stale`
//! on each citation; plain output prefixes stale citations with
//! `[stale]` (yellow on TTY).
//!
//! These end-to-end checks exercise `kebab ask`, which requires a real
//! Ollama on `127.0.0.1:11434` (same constraint as
//! `kebab-app/tests/ask_smoke.rs`). Both tests are therefore
//! `#[ignore]` by default — run with
//! `cargo test -p kebab-cli --test wire_ask_stale -- --ignored`
//! against a live Ollama.
//!
//! The `[stale]` rendering logic itself is also covered by a unit test
//! in `kebab-cli/src/main.rs` (`tests::plain_marks_stale_citation_*`)
//! that constructs a synthetic `Answer` and pipes it through
//! `render_ask_plain_citations` — that path is the always-on guard.
//!
//! Shared TempDir / ingest / backdate helpers live in
//! `tests/common/mod.rs`; see also `wire_search_stale.rs`.
