Shamann Walton

Present at 19 of 19 roll calls at the Board of Supervisors, roll call through Apr 14, 2026

From the clerk’s own record. We don’t compare members on it.

Absent 0. Oct 28, 2025 to Apr 14, 2026. The clerk’s record covers 19 of the 39 meetings we hold, through Apr 14, 2026.

• San Francisco County Transportation Authority Board: 0.5 min of speech a meeting, range 0.1–0.9. In the same range as seven other members.
• Rules Committee: talk time not compared. Presides over its meetings, so isn’t compared with the members.
• Budget and Appropriations Committee: talk time not compared. Fewer than four members can be compared fairly.

We identified Walton’s voice at 94 meetings across four bodies. A meeting missing here means we couldn’t attribute the voice, not that Walton was absent. Claude and Gemini each read every transcript with that day’s roster. A voice gets Shamann Walton’s name only when both agree and a code check finds the name said on, or just before, their turn. Voices our transcripts merge with someone else’s are never attributed, so every count here undercounts what Walton said. For councils and their committees, of 410 lines drawn, 352 were right, 0 wrong and 1 unclear, and the checkers couldn’t judge 57. We have since removed the voices behind 110 of those lines (0 wrong, 1 unclear, the rest we had already held for other reasons). Of the 300 lines we still publish, the checkers could judge 268: all 268 right (90% lower bound 0.99). They couldn’t judge the other 32. The check is one sample pooled across the five cities, not of Walton or of San Francisco alone.
