Function eval_config_table 

pub fn eval_config_table(table: &ConfigTable, k: usize, inputs: &[i64]) -> i64

Evaluate the reconfigurable array configured as datapath k on inputs. Because the reconfig proof certifies config == k ⇒ array ≡ island k, the array’s output IS island k’s — so this evaluates the placed island directly. The result is the value the physical fabric would drive when its config word is block_config(k).
