Not sure about this part, though I notice that the two rows have different "TaggerDate" values by ~15 seconds.

This part, though, is normal for "packed-refs". The first line shows the annotated tag object's hash ("66c41d67da8") and the tagged object's hash ("2fcfd00ef8"). You can see that "2fcfd00ef8" matches the tagged commit output by "git show". The leading "^" on the second line is how Git knows the line identifies a peeled tag's target rather than the start of a new ref. If your "packed-refs" starts with "peeled" (and maybe "fully-peeled") then every annotated (or signed) tag in the file should have a second line prefixed by "^".

Hopefully this at least resolves part of your question!
