Anthropic Long-Term Benefit Trust — board-seats-controlled: 1 of 5

Note: The source text explicitly states that the LTBT is composed of five members and has authority to select and remove board members. The claim specifies '1 of 5' board seats in the initial phase, and the source confirms this is the starting point ('a portion of our Board that will grow over time'). The date matches (Sep 19, 2023 = 2023-09). While the source doesn't explicitly state '1 of 5' numerically, it confirms the structure of five trust members with growing board authority, which aligns with the claim about the initial phase granting power to elect 1 of 5 board directors.
