The playthroughs that build the code map never reach this, so the automatic pass leaves it as data. It is not: the bytes decode cleanly as code from the first byte, and forcing it here costs nothing -- the round-trip check still reassembles the whole game byte for byte, which it could not do if the split were wrong.

The handler for sprites $80 to $8E -- the keys and the objects that kill the four big monsters. Like the food it does nothing but wait: every frame it asks whether the player is standing on it, and only then acts.

Picking something up is not free. The player can hold three things, and taking a fourth pushes the oldest out, so the three calls at the end run in the order they have to: DROP_CARRIED first, while the item about to be lost can still be read, then SHIFT_CARRIED to make room, then REMEMBER_CARRIED to put the new one at the front.
