Silence you can check
The headless run is meant to make no sound, and the log now proves it. Every sound request is refused before it reaches the audio engine and the listener is muted. Each run's summary records that audio was off and how many requests were refused.
The way there had a lesson in it. An early version leaked sound voices, and 25 minutes into a run it flooded the engine with 24,000 errors. The long run is now clean at 17x game speed. A mute that only lowers the volume is not the same as sound that is never requested.
The second route
Starting from the repaired submarine, the Watch AI sails her to the Nordic Base, does the base's jobs and carries on without help. A 45 minute run finished with 84 dives home, 1 lost, 0 errors and 0 stalls. A golf round that blocked the voyage, because the AI answered the captain's "play a round" when it should have been sailing, is fixed.
Art and store fixes
The stray "PERSEPHONE" lettering is gone from the bow and cutscene hull, since the ship is the Topside. Broken labels are fixed on the station maps, the escape trunk, the vault door and a mooring clamp. The leaderboard no longer puts the install id in the web address.
