+A route or nav node that gates on a permission no installed plugin declares now logs a boot warning
+naming the plugin and the permission. The admin screens offer only declared permissions, so nobody can
+be granted such a gate from them. Add the name to the plugin's `permissions` to silence the warning.

 ## Details
 
-### 51. Move the test-only tooling out of the runtime folders `src/ui/` and `src/http/`, and keep the README file map true.
-
-`src/ui/stylesheet-floor.ts` imports a devDependency and only its test uses it; `src/http/app-harness.ts`
-is a test fixture. Both sit beside runtime modules, and the README file map omits them. Seats also
-named `src/http/builtin-routes.ts`, which holds no routes.
-
-### 52. Make `positive` in `stylesheet-floor.ts` readable without tracing it by hand, and state why a custom property's value is checked.
-
-Most scoring seats named `positive` (`:119`) with `walk` and `property` as opaque. Split it
-into named steps, say in the header that an unsupported value in a custom property blanks every
-`var()` that reads it, and keep the README's "Two browser floors" pointing here. It is the home of
-the 3am answer.
-
-### 6. Warn at discovery when a route or nav node gates on a permission no plugin declares.
-
-Declaring stays optional on purpose, but the picker is built from declarations only, so such a route
-is ungrantable from the GUI and answers a permanent 403. A warning, not an error.
-
 ### 23. Give list pages one view-model helper from query to pagination, instead of ~40 hand-written lines each.
