You have 1 billion years to pack. Start now.

Meanwhile, just run-of-the-mill cosmic rays have huge impacts on
planet dirt. I'm processing some cloud data for a project
and both cloud height and cloud amount (percent of sky covered)
is highly dependent on cosmic rays detected around the world.

There is even some indication cosmic particles modulate earthquake
activity e.g. affecting the average depth of major quakes.

Sirius A isn't massive enough to go supernova on its own, much less to
produce any kind of gamma-ray burst, and A and B are too far apart.
