In your case and mine hardened off means the sap has fallen and no longer in the trunk or limbs, AKA dormant.
One of the worst things to happen and I have had it happen here with other shrubs is for the plant to come out of dormancy and then have a good freeze.
This will split the wood in the tree or bush and sometimes kill it out right.
