It is a bit funny that they do not exactly align.

    "object name" aka "object ID"
    "$type object name" aka "$type ID" for type in (commit, blob, tree, tag)

In any case, we should add "object ID" and other "$type ID" to the
glossary, if you are going to use it very often.  We have entries
for spelled out "identifier" but I do not think "ID" is there yet.

Thanks.
