//! TUI Integration Smoke Tests (bead z61x9)
//!
//! These tests verify the TUI works correctly with the fully integrated stack:
//! - frankensqlite (storage backend)
//! - frankensearch (search pipeline)
//! - franken_agent_detection (connector discovery)
//!
//! Test scenarios:
//! 1. Launch TUI with test index → verify initial render (no crash)
//! 2. Search query → verify pipeline executes without panic
//! 3. Apply agent filter → verify filtered search executes
//! 4. Switch search mode (lexical/semantic/hybrid) → verify no panic
//! 5. Verify footer stats (from frankensqlite)
//! 6. Verify asciicast recording with populated index
//! 7. Multi-agent integrated stack exercise
//!
//! NOTE: Some search queries that return results currently fail with frankensqlite
//! "OpenRead" errors during the result-loading phase. This is a known limitation
//! of the frankensqlite migration (the search index pipeline works, but loading
//! full conversation details from the DB fails for certain SQL patterns).
//! Tests assert no-panic rather than success for these paths.
//!
//! All tests use `--once` / `TUI_HEADLESS=1` or CLI search (--json) for
//! non-interactive execution.
