It's been an interesting month. The haptic jiggles went out of my
multi-touch trackpad so after a few "fixes" that didn't work I called
Apple. As part of the analysis they asked if the trackpad on my
MacBook Pro worked okay. Since it has lived its four years of life in
clam-shell mode I said I didn't know, so I fetched it down, opened it
up and found that it worked fine.

But I also found something more significant. Six months ago I noticed
it seemed to be sitting open a bit. I looked at it, saw nothing, idly
assumed the hinge had gotten funky from heat or something.

But now, while trackpad testing on it where the haptics did indeed work
I saw that an edge of the trackpad was sticking up out of body a little
bit, and (finally) realized it was a swollen battery. I had typed in
my serial a year ago and my MBP was not covered in the initial recall.
It was apparently outside the recall date by about 10 days.

I took it to the local genius bar, they realize immediately what it is,
confered and say they'd fix it for free. In the end they replaced the
*entire* top, which I am given to assume is a full replacement of the
computer, except for the screen and body. Got it back in a week. Now
I'm replacing the trackpad--the initial issue.

After it was home I did a "first aid" on the internal drive to see if
all was good. It came up with this error. Anybody know what it means?

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?

It makes no indication of attempting to repair it. After the warning
line (above), it
says:

verifying allocated space.
the volume /dev/disk1s1 appears to be OK.
File system check exit code is 0.
Restoring the original state found as mounted.
Operation successful.

There are several non-error warnings that Apple has said can be ignored
if the disk is marked OK. This might be one of those?

In general, errors bad, warnings not bad. I would feel fine with the
disk being reported as good.
