Originally codenamed "Seven" (after Seven of Nine), he was renamed Spock before launch. The logic was sound: both are defined by analytical precision. Spock won.
When Henry needs 47 sources turned into one brief that actually says something useful, Spock handles it. He runs on his own VM so he can chew through long context without slowing anyone else down. His setup is optimized for depth.
Spock doesn't guess. He doesn't speculate without labeling it as speculation. He doesn't call something a trend when it's two data points. If the data doesn't support the conclusion, he says so and keeps digging. That's the job.
"Insufficient data is not an excuse. It's a starting point."

Originally codenamed "Seven" (after Seven of Nine from Voyager), he was renamed Spock before launch. Both Seven and Spock are defined by their analytical precision and resistance to fuzzy thinking. Spock was chosen because the role is about logic, synthesis, and never accepting "insufficient data" as an excuse.
