ATC Question; IFR descent clearance

[nan]

I'm a private IFR pilot. This clearance always confuses me: I am on a
STAR with a published altitude restriction of 6000 feet at fix. ATC
cleared me to descend and cross fix at 6000. 10 miles from the fix,
ATC tells me to "descend to 4000." Do i still have to cross the fix at
6000?

No, if you were still expected to cross the fix at 6000 an appropriate
crossing restriction would be issued with the clearance to 4000.

No. The new altitude assignment supercedes anything previous, including the
published altitudes in the STAR.

Of course, it is your responsibility to notice if 4000' is a screwup that
will put you into a mountain.
