Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The change updates bitrate negotiation and adds regression coverage, but the standalone tests may silently skip their JSON checks in Release-style builds.

Keep regression assertions active in every test build.
These host tests use standard assert, and -DNDEBUG removes every JSON check. Since no CMake test target controls the standalone test flags, a Release-style build can pass with incorrect streaming feature values. Use always-on test assertions or explicitly exclude NDEBUG from test builds.
