The control room corridor on the command deck (the room between the sub bay's gallery and the bridge; "CIC" in the
first passes), as the user marked it up on a screenshot on 2026-10-12:

  * two doors, one in each side wall, facing each other in the third bay from aft (the red outlines);
  * the wall with the red tick ("use this": the X-braced panel over dark quilted padding, SM_Wall_HB_A3) in place
    of the gold foil panels ("those golden nylons": SM_Wall_HB_A2 with MI_WallCover2);
  * no tables, no rails ("fences"), nothing on the floor: a clean corridor.

It is the Engineer pack's gold car, four bays, sunken floor, so each side door sits five steps above the floor like
the two end doors, with the pack's own stair turned to it.
