 Or that particle transforms are time-reversible (within the limits of later and previous interactions) and that β- and β+ are time mirrors of each other?
 
It is not time reversible in the sense that a β− decay can be
'undone' by a β+ decay so we get the same isotope back.
Example of β− decay:
Carbon-14   with 6 protons and 8 neutrons decays into
Nitrogen-14 with 7 protons and 7 neutrons + electron and antineutrino
Nitrogen-14 is stable
Example of β+ decay:
Carbon-10 with 6 protons and 4 neutrons decays into
Boron-10  with 5 protons and 5 neutrons + positron and neutrino
Boron-10  is stable
Note that the decay tend to make the number of protons and neurons
(more) equal.
Isotopes with equal (or more balanced) number of protons and neutrons
tend to be stable.
