How do I determine which paths are used for the composer cache?

https://getcomposer.org/doc/06-config.md#cache-dir

Is there a way I can verify which paths it is actually using?

And secondly the documentation does not seem valid - I don't have any ~/cache directory OR $XDG_CACHE_HOME/composer...

If you are looking for your global composer configuration you can use the config command:

composer config --global --list

Sample output form my docker container:

$ composer config --global --list | grep cache
[cache-dir] /tmp/cache
[cache-files-dir] {$cache-dir}/files (/tmp/cache/files)
[cache-repo-dir] {$cache-dir}/repo (/tmp/cache/repo)
[cache-vcs-dir] {$cache-dir}/vcs (/tmp/cache/vcs)
[cache-ttl] 15552000
[cache-files-ttl] 15552000
[cache-files-maxsize] 300MiB (314572800)

You might have missed the last part of the documentation, though:

cache-dir

Defaults to C:\Users\<user>\AppData\Local\Composer on Windows, $XDG_CACHE_HOME/composer on unix systems that follow the XDG Base Directory Specifications, and $home/cache on other unix systems. Stores all the caches used by Composer. See also COMPOSER_HOME.

Source: https://getcomposer.org/doc/06-config.md#cache-dir, emphasis mine.

So I think, here you missred $home/cache to be ~/cache when it is actually $COMPOSER_HOME/cache

From my docker container still, which confirm the /tmp/cache folder raised by the config command:

$ echo $XDG_CACHE_HOME

$ echo $home

$ echo $COMPOSER_HOME
/tmp

So, in short, if set, the $COMPOSER_HOME takes the precedence:

$ echo $COMPOSER_HOME
/tmp
$ unset COMPOSER_HOME
$ echo $COMOPSER_HOME

$ composer config -gl | grep 'cache-dir'
[cache-dir] /root/.composer/cache
[cache-files-dir] {$cache-dir}/files (/root/.composer/cache/files)
[cache-repo-dir] {$cache-dir}/repo (/root/.composer/cache/repo)
[cache-vcs-dir] {$cache-dir}/vcs (/root/.composer/cache/vcs)

$ echo $HOME
/root
$ whoami
root

As you can see here, after unsetting $COMPOSER_HOME, I end up with the home of my user (root here, which would be a bad practice for composer but I am on docker, for the demo).

So what you should read in

By default it points to (...) /home/<user>/.composer

Source: https://getcomposer.org/doc/03-cli.md#composer-home

Is

By default, when the variable is not set, it points to (...) /home/<user>/.composer
