 | WinterCMS websockets plugin dissolved into the framework `lighthouse` package (Phase 11 D-16) | Realtime is transport-neutral framework code (drivers, authorizer registry, broadcasts); the app only binds config, the collection/wishlist authorizers, the Mount call, the ws-api bucket and the Album binding, so a separate app plugin would be an empty shell | ✓ Good (Phase 11 plan 11-03) |
 | Framework and application in two repos from day one (`summercms.go`, `fonoteka.go`) | Retrofitting the split later is more disruptive; shared stack plugins can be extracted for keios.eu without touching the framework; the framework never imports an app | ✓ Good (Phase 3: fonoteka.go workspace, user + fonoteka plugins, app.Handler test seam) |
 | Shared core plugins live in their own `sm-<name>-plugin` repos, mounted into each application as git submodules (first: sm-user-plugin, module `git.golem15.com/golem15/sm-user-plugin`) | A second application (sm-summercmsio-app) exists and the Journal port is next; one copy per core plugin instead of forks; supersedes the Phase 1 keios.eu trigger (`.planning/notes/core-plugins-own-repos.md`) | ✓ Good (2026-10-02, quick 261002-esz) |
+| OAuth identities live in sm-user-plugin; Index/Destroy are host-mounted on the JWT group | Social-login rows are a user-plugin table (D-01); routes stay off `/_user` so the host owns Winter 404 and `throttle:10,1` | ✓ Good (Phase 14.1, 2026-10-05; corpus 175/175/0) |
