//! Round15 raw integration coverage for Composio, credentials, app state, and threads.
//!
//! Everything stays on loopback mocks and temp stores. The tests drive public
//! Rust surfaces so coverage lands on the same ops/tool paths used by JSON-RPC
//! and the agent runtime without real Composio, keychain, or backend calls.
