lesavka/testing/tests/client_microphone_source_contract.rs

//! Include-based coverage for microphone source-name routing.
//!
//! Scope: include `client/src/input/microphone.rs` and cover selected-source
//! routing heuristics for launcher catalog names.
//! Targets: `client/src/input/microphone.rs`.
//! Why: launcher-selected Pulse source names must not regress to PipeWire
//! negotiation when the catalog already provides a concrete Pulse device name.
