Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet), blind second pass from passage text and citation only, no repository access, 2026-10-31).

Found in the transcript text, spoken by the Goldman Sachs CEO on the call: 'It started with productivity and a more narrow component of the firm called engineering, but based on leveraging the firm's relationships with a number of different large language model providers'. The passage stops mid-sentence, and the match is exact. The transcript uses straight apostrophes after normalization.
