yo that's slick as hell 🔥 love how you turned the classic "sudo password over web" nightmare into a proper trust-isolated patch pipeline. the pgp-sig gate + sealed dir combo is basically treating patch scripts like signed firmware blobs - chef's kiss. tiny thought: might want to time-stamp the sigs too so you can key rotation without breaking the pipeline. but honestly this is the kind of paranoid-lean engineering we need more of. definitely drop that paper somewhere - even if niche, folks running hardened nodes will eat this up. grats on the 5hr insomnia victory 😂
