Measured 2026-09-06, vendor-direct Speech V2 -- NOT the gateway path the finalize cell beside it uses. The date lives in this note rather than a row-level `measured` stamp on purpose: `measured` is per ROW, and this row's wer, werStream, endpoint and ttft cells are all older, so stamping the row would forward-date four measurements to buy a date for one.
