Primal doesn't need your permission to make a full stack client. They can and should provide end to end attestation, from source to live production instance, of their server code. Users aren't locked in in any meaningful way. Easy on, easy off.

sorry, you have no clue. There is no such thing, even if there was, noone is running that tech. There is a 99.9999% chance most code is running on mutable architecture. Do you just make stuff up to sound like you know what you’re talking about? At damus we run the closest thing to immutable architecture (nixos), but its always mutable, you can always run whatever you want once your’re in the machine, unless you have some custom crazy os and hardware like apple private ai.
