The report is regenerated after 10a39c5 so its stamp names the code it
describes. Speed is quoted as a range in the checklist because transcribe
seconds move with machine load (3.26s then 3.12s on this box) while WER,
denominators and word counts do not move at all.
Numbers: 258.18s of audio, WER 0.242 over 533 reference words, 80 audio atoms
and 563 word timestamps read back from the store, 0 out of order and 0 before
their own segment measured on the stored words.

Over 3 videos and 258.18 seconds of audio: word error rate 0.242 over 533 reference words (563 words heard), transcribed in 3.12 seconds.
Repeating the pass on the same machine gave WER 0.242 then 0.242; the transcripts were byte-identical. Decoding is greedy with no retry ladder, so a rerun is the same answer, not a new draw.
Ingested through the product path, the store holds 80 audio atoms from 3 sources carrying 563 word timestamps (0 out of order, 0 before their own segment) out of 133 atoms in total, checked on the words as stored rather than on the model's answer.
The captions are not a transcript, so this WER is not a bound in either direction: a caption that drops words also hides words the model dropped. The third row has only 36 reference words, where one word moves its rate by several points — read the denominators, not the decimals.
