 ## Phase 1 — core boundary and roulette
 
-**In progress.** `Command`/`View` exist and roulette is ported: the core builds
-a `RouletteView`, frontends send `Command`, and the TUI renders the view.
-Slots, blackjack and crash still travel through the `View::Text` bridge until
-Phase 2.
+**In progress.** `Command`/`View` exist and all four games are ported: the
+core builds a typed view, frontends send `Command`, and the TUI renders it.
+Remaining for this phase: the app screens (`Connect`, `Trust`, `Login`,
+`Lobby`, `History`) and removing `Key` from the core.
 
 - Introduce `Command` and `View`; move terminal-only concerns (prompt editing,
   wheel animation, interactive prompts) into the TUI adapter.
