I found a potential bug in kOS, where I try to create a maneuver node from a list of four values, and it returns the error "Cannot iterate on an object of type kOS.Safe.Encapsulation.ScalarIntValue. What's going on?

It's impossible to tell from that information.  Can you post the log to see the rest of the error dump, and what the kerboscript code was doing?  The full dump won't just show the error message, but will show where in the code it happened.

Where would I find this log?

It's a script error in your code.  Your code is written to assume the variable called 'data' is an array, because it's trying to get data[0].

But data isn't an array.  It's a single number. 

When you run this: 

set data to hillclimb["seek"](data, transferFit(targetBody), 1).

your hillclimb() function is returning a single number, not a list of numbers.

Here's my hill-climbing library. 

// Hillclimb Algorithm Library
// Kevin Gisi
// http://youtube.com/gisikw

{
  local INFINITY is 2^64.
  local DEFAULT_STEP_SIZE is 1.

  global hillclimb is lex(
    "version", "0.1.0",
    "seek", seek@
  ).

  function seek {
    parameter data, fitness_fn, step_size is DEFAULT_STEP_SIZE.
    local next_data is best_neighbor(data, fitness_fn, step_size).
    until fitness_fn(next_data) <= fitness_fn(data) {
      set data to next_data.
      set next_data to best_neighbor(data, fitness_fn, step_size).
    }
    return data.
  }

  function best_neighbor {
    parameter data, fitness_fn, step_size.
    local best_fitness is -INFINITY.
    local best is 0.
    for neighbor in neighbors(data, step_size) {
      local fitness is fitness_fn(neighbor).
      if fitness > best_fitness {
        set best to neighbor.
        set best_fitness to fitness.
      }
    }
    return best. // Returns a list
  }

  function neighbors {
    parameter data, step_size, results is list().
    for i in range(0, data:length) {
      local increment is data:copy.
      local decrement is data:copy.
      set increment[i] to increment[i] + step_size.
      set decrement[i] to decrement[i] - step_size.
      results:add(increment).
      results:add(decrement).
    }
    return results. // Returns a list of lists
  }
}

I'm not going to walk through your whole code.

Just print out the value of 'data' immediately prior to the line that complains.  Just before this: 

local t is data[0].

do this:
  

print "data is type: " + data:typename().
print "data is value: " + data.

and see what data really is.  It's not what you think it is.

Thanks, I'll do that.
