Maybe boiling, at the feed pressure, was avoided. Possible.

Speaking of possibly exciting hobbies, what happens if you boil peroxide

I gather peroxide cooling worked in Black Arrow, but I have the impression
from various distillation tales of woe that peroxide vapor is much less
stable than the liquid.  I might guess both that preheating the peroxide
could help with catalyzing or directly combusting it, and also that making
sure it stays liquid till then is indicated, but those are just guesses.

Perhaps it's a LOx/solid fuel hybrid and you want to cool your nozzle.

Yep, we discussed that at ARIS for cooling the nozzle with N2O for their
5kN hybrid. But N2O probably gets super critical which makes me nervous
:-(
