+The repo constitution is not another memory bucket. It is the local-law layer in
+a layered authority model:
+
+```
+base myth / global Constitution
+  -> repo constitution (.codewhale/constitution.json)
+  -> task packet
+  -> runtime policy
+```
+
+At conflict time, the **current user request for the task remains above the repo
+constitution**; the repo constitution supplies durable defaults and local law
+only when the active task packet and runtime policy leave room. Runtime policy is
+the compiled enforcement surface for the run, not a separate place for the model
+to invent new rules.

 **Why it helps weaker models (and users).** No overloaded command does five
 jobs; the model/user never has to disambiguate *which* `/memory` behavior they
 meant. `$systematic-debugging` self-documents what it invokes.
