D311 FIXED (root cause D336; 0 anomaly lines incl. Caverns combat), D288
CLOSED, D294 and D330 user-confirmed, D235 still unreproduced. D322: pools
healthy (leak hypothesis refuted); SFX soft-cap saturation in firefights
(D207/D241) plus a new periodic SDL output-queue overflow every ~314 s that
starts at the title screen, so it should reproduce headless.
