“You can’t grab the ladder because you’re not supposed to.” - I believe you can’t grab the ladder because the developers didn’t think the player could get to it, and so didn’t define it as a ladder in order to save resources.
“That part of the map is a hazard puzzle.” - The ladder itself is not a hazard puzzle. The hazard puzzle is made up of the hallway and the elevator shaft. I understand that the elevator shaft is intended to kill the player if they slip off the edge. However, if they slip off the edge the ladder sure as heck isn’t going to save them, because it is not reachable in that way. The ladder is only reachable by someone who carefully positions himself along the ledge, then aims right at the ladder and jumps/falls toward it (I failed 3x in a row when trying carefully to reach it).
“You have to figure out how to get across the slippery floor without falling down the open elevator shaft, and ideally without setting off the sentry trip lines.” - I agree.
“You can’t grab onto the ladder because it’s just there for detail,” - It is there for detail because I believe the level designer didn’t think the player would be able to reach it.
“there would be no point to there being, or even act against the point of the shaft if there was, a useable ladder there.” - I believe instead of “or even” you wanted an “and would even”. My apologies if English is not your first language. Anyhow, this is completely wrong. Look at the first screenshot. The ladder is tucked away in the corner, and is far away and 90 degrees-to the direction the player would be falling after slipping off the edge under normal use. Under normal circumstances, no one is going to touch that ladder after slipping off the edge in an organic fashion. Therefore, saying there is no point in having a usable ladder there is false, because it would not save someone who fell organically, and would therefore not defeat the purpose of the hazard trap.
This is, by the way, the only ladder I have encountered in the entire game (and in that I’ll include Opposing Force, Blue Shift, HL2 + ep1 + ep2) that I can reach but not use that is not visibly damaged. All other ladders that aren’t meant to be climbed are not reachable, or are damaged, or are climbable only to a certain point at which the ladder becomes damaged. This is the main reason I think this is a map design bug.
I have attempted to illustrate where you and I disagree, and why I feel how I do. Ultimately, it’s up to the Devs to decide if it’s a bug or not. I don’t want you to comment in any more of my threads because I think you insist on being right even when you are obviously wrong. Please stay away from me on these forums, and I will stay away from you.
