KNOWN FAILURE MODE, EXCLUDED FROM THIS NUMBER. On one corpus clip its decode collapsed into a repetition loop — 29 reference words became 339 of "co", more word errors than it makes across the rest of the corpus combined. That clip is excluded for EVERY provider, so it is absent from all seventeen rows. A caller can trigger this, and an agent would answer the garbage.
