Good.

The store implementation does, and then calls the file_callback. See
storeCreate() / createobj.
In the "ufs" familiy of stores the swafile number is allocated via a
bitmap. See storeUfsDirMapBitAllocate(). Basically starting at the
last allocated + 1, returning the next free number.

The cache_dir is first selected based on the policy set by
store_dir_select_algorithm (current policies are least-load and
round-robin), then the store implementation of that specific
cache_dir assigns the number within that store while the object is
being stored.
Ps. Please keep squid-dev in the CC list.
