-### The approval question
+## Approval (decided)
 
-Three things need a human "yes":
+One shared approval, on the admin app. One place to say no.
 
-- cutting the kids' internet (admin app),
-- filing a Paperclip job (Hub → Paperclip),
-- a project writing to the calendar (email adds an event, school books an
-  interview).
+The request says **what**, **who**, and **why**. You tap. It runs.
 
-Two options:
+Approval **is required** for:
 
-- **One shared approval.** The Hub (or a tiny approvals service) sends the request
-  to the admin app, you tap, it runs. One mechanism, one UI.
-- **One per project.** Each project asks in its own way. Simpler now, more to
-  maintain later.
+- a parental control change (cut or restore the kids' internet, change a schedule),
+- a Paperclip job.
 
-Recommended: **one shared approval.** The admin app already exists.
+Approval is **not required** for:
+
+- a calendar write. Email and school may add events. These are not dangerous.
+  Let them run.
