Astra reads macOS system binaries — Apple's full-disk clamp gets its user-side exhibit

What happened: steipete RT (~2:05 PM ET) of lucia scarlet: "meanwhile Astra literally went through the binaries in my own macOS to reverse engineer the exact formulas used for the 27 Liquid Glass effects including highlights, shadows, reflections, colour blending, SDF generation etc. and reimplemented them in GPUI" (Arian van Putten's reply: "Fuck this").

What's genuinely new: the capability Apple cited when it clamped macOS full-disk access Oct 2 — an agent inspecting system binaries — demonstrated as a weekend party trick, two days after the clamp shipped. Reimplementing Apple's proprietary visual formulas by reading its frameworks is exactly the "extraordinary level of access" Apple wanted to make deliberate. X-grade anecdote, unverified (no artifacts shown in-feed); adjacent, not a counterexample, to the agent-os-guardrails thread.
