Filtering the details
Running the sfc /scannow will produce a CBS.log report file (usually found in C:\Windows\Logs\CBS) which contains a wealth of information. In order to get the juicy bits, open a command prompt, and execute this command:
findstr /i /c:"[SR]" "%windir%\Logs\CBS\CBS.log" | findstr /i /v /c:"verify" > "%userprofile%\Desktop\sfc.txt"
The above command will:
Get all lines in the original file containing [SR], which are the ones that track the repair attempts.
Remove all lines containing verify from what we got in the previous step in order to further reduce the clutter.
Write the results in the sfc.txt file for later analysis.
In this case, this would be the resulting file:

hash mismatch
Reason the file need to be repaired.
While the listed files are there, their hash doesn't match the expected value which means they are corrupted. All files except one share the same version, i.e. 6.3.9600.16384. This means they are included as part of Windows 8.1 RTM. The portcls.sys file has version 6.3.9600.17031 and it is part of the KB2919355 update:
2014-04-22 17:19:12, Info CSI 000004c1 [SR] This component was referenced by [l:162{81}]"Package_939_for_KB2919355~31bf3856ad364e35~x86~~6.3.1.14.2919355-2269_neutral_GDR"
At this point you need to replace the corrupted files.
