 DTW native logs are retained byte-exact as bounded base64 plus SHA so malformed
 recognized bytes in diagnostic stderr cannot cause lossy decoding. Recognized
 JSON remains strict UTF-8 and cannot be repaired by this log representation.

+The frozen combination has now completed actual one-thread CPU ASR and Google

+zero excluded windows; **6/8 strict start hits**, versus gated base 4/8, and
+unchanged 6/8 overlaps. The gain against gated base is the Mars topic; Moon
