-# MVP Vertical Slice: Client-Server Wiring — Plan
-
-## Goal
-Prove the real Godot client and the real backend can talk: **a user can register/log in
-and see a list of worlds from the game client**. Nothing more. Gameplay, join-a-world,
-chat, avatar, Discovery search/tags/trending, Social/Economy/Trust & Safety are all
-explicitly out of scope.
-
-## Verified backend contract (as of this writing)
-- `POST /api/auth/register` — JSON body `{username, email, password, date_of_birth}`.
-  `date_of_birth` is a `YYYY-MM-DD` string. Returns `201 {access_token, token_type}`.
-  Rejects under-18 with `400`.
-- `POST /api/auth/login` — OAuth2 **form-encoded** (`application/x-www-form-urlencoded`)
-  `username` + `password` (this is NOT a JSON endpoint). Returns `{access_token, token_type}`.
-- `GET /api/worlds` — **requires auth** (`CurrentUser`), returns a JSON array of
-  `{id, name, description, visibility, owner_id, created_at}`. There is no unauthenticated
-  public-worlds path, so the worlds list screen can only be shown after login/register.
-- `GET /api/health` — unauthenticated, `{status, app}`.
-- Base URL: uvicorn default `http://127.0.0.1:8000` (must be configurable in the client).
-- CORS is irrelevant to the native Godot `HTTPRequest` client (no browser origin).
-
-## Task breakdown
-| # | Type | Task | Depends on |
-|---|------|------|-----------|
-| 1 | architecture | `ApiClient` autoload: HTTP + JWT storage + error contract | — |
-| 2 | implementation | Main-menu **login** wiring (form-encoded) | 1 |
-| 3 | implementation | Main-menu **register** wiring (JSON + age gate) | 2 |
-| 4 | implementation | **World list** screen consuming `GET /api/worlds` | 2 |
-| 5 | testing | End-to-end headless smoke test + manual verify | 1,3,4 |
-
-## Design decisions captured (resolved in task 1)
-- Token storage: in-memory singleton property for the MVP; a `save_to_disk` seam is left
-  open but not required yet (no re-login on restart in this slice).
-- Error contract: every call returns a discriminated result (`ok`/`error`) so callers
-  never crash on network failure; non-2xx surfaces `{status, detail}` from the backend.
-- Base URL: read from a ProjectSetting, defaulting to `http://127.0.0.1:8000`.
-- Login is form-encoded; register is JSON — the client helper must support both content types.
