Self regulation, reminds me of a George Carlin comedy skit of humans being
a threat to the planet and "shaking us off as a surface nuisance" which
reminds me of the Gaia hypothesis. May be true throughout the universe -
except for white dwarfs which are 'degenerates' of nature and self destroy,
a kind of self regulation as a whole in nature. Interesting.

In the sail-supported reflective sphere we've been talking about, in which
most of the heat can't escape, the star will overheat and expand just
enough to destroy the sphere, after which it will settle back down again,
having swatted the mosquito that was bothering it. :-)
In a proper Dyson sphere -- one that radiates the star's full energy
output as waste heat, after making use of it -- there's no issue.
