The top case of 2015 and earlier MacBook Pros includes the metal body,
battery, keyboard and trackpad. It does not include the main logic board
or anything attached directly to it (e.g. ports, CPU, GPU, memory,
storage), nor the display, nor the lower cover.
I know this because I had my Late 2013 MacBook Pro top case replaced in
June (just before this model went "vintage" which ended its
serviceability) due to it starting to report that the battery needed
servicing (about 650 cycles, charge capacity was around 80% of new,
occasional sudden shutdowns at moderate to high charge levels therefore
not always able to deliver peak current, but no sign of swelling).
I can tell I still have the previous display (already replaced earlier
due to the antireflective coating issue), ports, storage and lower
cover. My keyboard was definitely replaced as I previously had
significant wear on several of the keycaps. I can't tell the difference
for the trackpad. The battery went to 0 cycles and 100% of its original
charge capacity, has a new serial number and is working fine again.

The number of directories found by scanning the volume (392366) does not
match the expected value which was recorded in the volume information
(302101). Therefore the file system has some degree of corruption.
Was Disk Utility able to repair it?
