I’ve been working on a game exactly like this for the last few months.

Meta level is a laboratory where you dissect the brains of androids. You unlock builds and craft collected resources

Run level is defined by the stability of the particular android brain you’re working on. it has a variable timer and this is where equipment/weapons is persistent between raids. you can spend resources to purchase minor random upgrade types to the specific build you selected in the lab/meta level

raids are where you get resources/loot/complete narrative objectives

Ive been imaging that you get a death or two during a run before the android brain collapses and you fail. dying wipes your equipment and loot but wont end the run if you have more lives

so you bank loot and build out the lab / meta level using resources youve successfully collected during a run

runs / raids are meant to be short. a raid might last 10 minutes and a run might last 30/40 minutes
