No the reader doesn't create new packages. The reader would signal an
error if the package "TEST" doesn't exist.

Yes, the reader would use (intern "A" "TEST") to find/create the symbol.
If you had written 'test:a then the reader checks that "A" is an
external symbol in "TEST". If it's not external then the reader signals
an error.

The result of (intern "A" "TEST")

The hashcode of a symbol should be independent of the package it belongs
to. Interning/uninterning symbols or renaming/deleting packages should
not have any effect on the symbols hashcode.
