Persist audio overrides keyed by game image name (coop_audio_overrides.ini next to the exe) so a known-bad game is auto-corrected on its next launch: on attach to a guessed stream the host applies any saved override, and a manual Override now saves too. A format the hook catches exactly at IAudioClient::Initialize is auto-saved as that game's override (ground truth); if it overwrites a differing stored value, a warning is logged. Host-originated log lines now reach the Log window via IpcServer::host_log (color-coded). Validated live (harness): a pre-seeded override for coop_tone is auto-applied over the guess (state -> manual override, 48000/2/16). audio_overrides_test covers persist/reload/case-insensitive lookup/differing-overwrite.
