+Brainstorm and spec a scoped Admin information architecture for the
+three-tier model (deployment → project → collection), and the
+collection-management surfaces that hang off it.
+
+Problem: §22 delivered scoped roles ({owner, contributor} at {global,
+project, collection}) but the admin *page* IA never followed. Today
+/admin is mounted only at deployment/site scope (App.jsx:348), and it
+mixes grains that don't belong together:
+  - Retired RFCs (a collection-grained concept) live in the global,
+    site-owner-only admin (Admin.jsx:49–54, §13.7) — wrong scope.
+  - Graduation queue is already project-flavored (useProjectId()) yet
+    also sits at site level.
+  - Create-project / create-collection actions exist and work
+    (POST /api/projects, POST /api/projects/<id>/collections; modals in
+    CreateProjectModal.jsx / Directory.jsx) but are only reachable via
+    the multi-item directories, which the N=1 landing logic
+    (DeploymentLanding, App.jsx:448) redirects past — so an Owner on a
+    single-project/single-collection deployment has no UI path to manage
+    or create siblings. Effectively API-only today.
+  - In-app metadata field-schema config is deferred (decision D8 in
+    docs/design/2026-06-06-configurable-collection-metadata.md): a
+    collection's `fields:` are edited in .collection.yaml in git, with
+    no in-app surface. This is logically a Collection-Admin capability.
+
+Goal: produce a Solution-Design spec for a coherent Site Admin / Project
+Admin / Collection Admin IA. Don't write code this session.
+
+```

+## Deferred decisions
+
+_Autonomous-mode low-confidence calls the driver made and would have
+liked operator input on. Appended as the session runs; surfaced at
+finalize. Empty if none._
