Demotie via TeamManager; allow-list-leden demoteer je door ze van de lijst te halen |

 | 007 | Migratie = structuur, hook = configuratie | De OIDC-provider wordt bij elke start (en per cron-minuut) gereconcilieerd vanuit `ENTRA_*` env door `pb_hooks/entra_oidc.pb.js`; een one-shot migratie die van deploy-time env afhangt kan OAuth2 anders permanent uitschakelen |
 | 008 | Hook-helpers via `require(`${__hooks}/utils.js`)` | De JSVM draait elke hook-callback als geïsoleerd programma; top-level functies zijn níet in scope op call-time |
 | 009 | `createRule: '@request.context = "oauth2"'` op `team_members` | PocketBase past de createRule toe op de OAuth2-sign-up (eerste login maakt het record aan); `null` blokkeerde élke eerste login met 403 (issue #22). De context-rule staat alléén de OAuth2-flow toe — anonieme REST-creates blijven geweigerd |
 | 010 | Claims uit het Entra **id_token** (`userInfoURL: ""`) + UPN-fallback voor e-mail | Graph `/oidc/userinfo` geeft géén `email`-claim voor accounts zonder mail-attribuut → 400 bij eerste login (issue #24). Het id_token bevat altijd `preferred_username` (UPN = primair e-mailadres bij Respellion); `entra_oidc.pb.js` gebruikt die als fallback (regex-guard tegen guest-UPN's) en logt gefaalde OAuth2-pogingen naar de containerlog |
+| 011 | `updateRule: '(@request.auth.id = id && @request.body.role:isset = false) \|\| @request.auth.role = "admin"'`, `deleteRule: '@request.auth.role = "admin"'` | TeamManager-rosterbeheer werkt nu voor app-admins (issue #27). De `role:isset`-guard sluit tegelijk de privilege-escalatie waarbij een gebruiker zijn eigen `role` naar admin kon patchen; onboarding raakt `role` niet en blijft self-service |
