Is it better to use checksums with or without extension?

ex.

Test.rar
Test.sha3

Test.rar
Test.rar.sha3

It's a matter of taste with a flavor of practicality.
The without-extension approach is better but is not universal.
The with-extension approach is not better but universal.
For instance, in the case of multiple identical file basenames, the former is not applicable while the latter is the only option:
basenames are differ:
test.rar, trial.7z, probe.zip > test.sha3, trial.sha3, probe.sha3
basenames are the same:
test.rar, test.7z, test.zip > test.rar.sha3, test.7z.sha3, test.zip.sha3
That is how I use it if the individual hashsum files are needed.
Surely, the above is IMHO.

To me you must be as less ambiguous as possible, so the most preservative is to add checksum name at the end of calculated fullname. (i.e test.rar + test.rar.blake3 )
Another way is you do a checksum file for multiple files that have to go together.
