Follow-up to #22. Registers xai/grok-voice-transcribe-1.0 (same adapter) and publishes it on the benchmark page's six samples, so the generation step is measured, not assumed.

  • 500 of 500 utterances, 1.50 h audio, USD 0.15.
  • strict-de 6.84 / 7.51 / 8.55 / 11.16 % (avemio / fleurs / mls / voxpopuli), mean 8.52 % vs. 2.0's 8.15 %. BLEU 34.13 (spc-test), 37.10 (fhnw).
  • 2.0 is better on FLEURS and on both Swiss BLEU scores, level on MLS, worse on VoxPopuli.
  • make verify: 35 rows reproduced. pytest tests/test_xai_adapter.py tests/test_harness.py: 12 passed.

The predecessor of 2.0 and xAI's default when `model` is omitted. Same
adapter, same request; registered so the generation step can be measured on
the same samples instead of taken from the release note.

Same six samples, same settings (language=de, format=true). 500 of 500
utterances, 1.50 h, USD 0.15.

strict-de 6.84 / 7.51 / 8.55 / 11.16 % (avemio / fleurs / mls / voxpopuli),
mean 8.52 % against 2.0's 8.15 %. The step is not uniform: 2.0 wins clearly
on FLEURS and on both Swiss BLEU scores, is level on MLS, and loses on
VoxPopuli plenary speech. 1.0 writes mostly lower-case without punctuation,
which lifts its raw-text CER above WER on fleurs and mls-de.

make verify: 35 rows reproduced.
