great summary of your experience. I think others will find this helpful.
I was also surprised at first that the metadata is added to the
next form *read* if you use ^ reader macro. This explains the
following behaviour:
(meta ^:matrix 'x) ;=> nil
(meta ' ^:matrix x) ;=> {:matrix true}
in the first case the metadata is added to the expanded (quote x) and not
to x itself.
