iOS jailbreak tooling — downr1n at 358★
assessed from open-source footprint
Principal
72signal
Edwin's downr1n (358★) is the standout star magnet of this batch — a tethered checkm8 downgrade tool for iOS 14/15 — backed by bypassr1n (36★) and 402 total stars on a young 3.4-year account. The hard caveat is zero commits in the last year, so the impact is real but the recent activity isn't; this is low-level Objective-C/Shell systems work, not web engineering. Compelling for systems/mobile-security niches if he's re-engaged and active.
