+# Sprint 14 — Zuhause & Garten Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add the garden/home area below the hospital floors, with interactive gift boxes, a tea pot, and camera navigation buttons in both directions.
+
+**Architecture:** The Home area lives at world position `(0, 720)` — directly below Floor 0. `RoomNavigator` gains `go_to_home()` / `go_to_hospital()` which tween the camera to `Vector2(640, 1080)`. A `HomeButton` component with `@export var go_to_garden: bool` drives navigation in both directions. No new autoloads; everything hooks into the existing `RoomNavigator` autoload.
+
+**Tech Stack:** Godot 4.6.2, GDScript (static typing), ColorRect placeholder visuals, Tween animations
+

+# Sprint 5-7: Erdgeschoss — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Four fully interactive ground-floor rooms (Reception, Gift Shop, Restaurant, Emergency Room) with horizontal room-to-room navigation and an ambulance drive-in animation.
+
+**Architecture:** Floor 0 rooms are laid out side-by-side at 1280 px intervals along the X axis. `RoomNavigator` is extended to tween the camera both horizontally (room index) and vertically (floor index). `NavigationArrow` objects placed at room boundaries handle left/right navigation. When `go_to_floor()` is called, the room resets to index 0. The ambulance in Emergency Room drives in automatically the first time the player navigates there.
+
+**Tech Stack:** Godot 4.6.2, GDScript (static typing), placeholder ColorRect graphics, existing `InteractiveObject` + `DragDropComponent` base classes.

+## Self-Review: Spec Coverage Check
+
+| Sprint 5-7 requirement | Covered by |
+|------------------------|-----------|
+| Empfang komplett | Task 3: bench ×2, bell, potted plant, number display |
+| Geschenke-Shop | Task 4: full scene with shelf, 4 interactive objects |
+| Restaurant | Task 5: full scene with 3 tables, 4 interactive objects |
+| Notaufnahme | Task 7: full scene with ambulance bay, table, IV stand |
+| Krankenwagen-Animation | Task 6: drive-in on room_changed, drive-out on tap |
+| Horizontal room navigation | Task 1 + 2: RoomNavigator + NavigationArrow |
+| All rooms accessible from game | Task 8: all wired up in Main.tscn |
+
+**Placeholder scan:** All code blocks are complete. No "TBD" or "implement later" present. UIDs are convention-based and may be regenerated by Godot on first open — this is expected behavior.
+
+**Type consistency:** `room_changed(floor_index: int, room_index: int)` signal defined in Task 1 and consumed in Task 6 (`_on_room_changed`). ✓ `go_to_room(floor_index: int, room_index: int)` defined in Task 1 and called in Task 2 (`NavigationArrow._on_pressed()`). ✓
+
+---
+
+## Smoke Test Checklist (manual, on device after completion)
+
+- [ ] Game starts at Reception (camera center visible, green background)
+- [ ] "→" arrow in Reception navigates smoothly to Gift Shop
+- [ ] "←" arrow in Gift Shop navigates back to Reception
+- [ ] Full chain: Reception → Gift Shop → Restaurant → Emergency works both directions
+- [ ] Elevator Up from Reception navigates to Floor 1
+- [ ] Elevator Down from Floor 1 lands at Reception (room 0), not Emergency Room
+- [ ] Tapping flower/bell in Reception plays bounce animation
+- [ ] Navigating to Emergency Room for the first time: ambulance drives in from right
+- [ ] Tapping ambulance after it's parked: drives back out
+- [ ] Tapping ambulance again: drives back in
+- [ ] Dragging Bunny character across rooms works correctly
+- [ ] Save/load preserves Bunny position after app restart

+# Sprint 8-10: 1. Obergeschoss — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Four fully interactive first-floor rooms (XRay, Pharmacy, Lab, Patient Room) with the X-ray machine's plate slide-in animation as the highlight feature.
+
+**Architecture:** Floor 1 follows the same side-by-side room layout as Floor 0 — four rooms at X offsets 0, 1280, 2560, 3840 within the `Floor1` node. `XRayMachine` is a new custom component (like `Ambulance`) with its own state machine. The existing `NavigationArrow` and `ElevatorButton` components are reused unchanged. `Main.tscn` is updated to replace the Floor 1 placeholder nodes with the real room scenes.
+
+**Tech Stack:** Godot 4.6.2, GDScript (static typing), existing `InteractiveObject` base class, placeholder ColorRect graphics.
+

+| Create | `scenes/objects/XRayMachine.tscn` | Machine body + viewer screen + sliding plate (all ColorRect) |
+| Create | `scenes/rooms/floor1/XRay.tscn` | Exam table, XRayMachine instance, PlasterStation |
+| Create | `scenes/rooms/floor1/Pharmacy.tscn` | Medicine shelf, counter, 4 positive medicine objects |
+| Create | `scenes/rooms/floor1/Lab.tscn` | Lab bench, 4 interactive lab objects |
+| Create | `scenes/rooms/floor1/PatientRoom.tscn` | 2 beds, TV, bedside table |
+| Modify | `scenes/main/Main.tscn` | Replace Floor1 placeholder with 4 rooms + nav arrows; move elevator buttons |

+- Lab: x=2560 (room index 2) — camera center world (3200, -360)
+- PatientRoom: x=3840 (room index 3) — camera center world (4480, -360)
+
+**XRayMachine visual layout (local space, origin = machine base center):**
+- MachineBody: grey ColorRect 80×200 at local (-40, -200) — tall vertical machine
+- MachineArm: grey ColorRect 220×24 at local (-40, -180) — horizontal arm over table
+- ViewerFrame: dark ColorRect 80×60 at local (-40, -195) — screen housing on machine
+- Viewer: very dark ColorRect 66×46 at local (-33, -189) — screen, lights up during scan
+- Plate: Node2D child, starts at local (-50, 20); contains PlateBody (200×14 ColorRect)
+  - PLATE_PARKED_X = -50.0 (behind/inside machine, hidden)
+  - PLATE_ACTIVE_X = 130.0 (extends to the right, under the exam table)
+
+**Floor1 elevator buttons (moved to avoid overlap with nav arrows at x=1200):**

+3. In the Floor1 section: **remove** the placeholder `Background`, `FloorLabel`, `FloorRect` nodes
+4. **Add** 4 room instances to Floor1 at x offsets 0, 1280, 2560, 3840

+6. **Add** 6 NavigationArrow instances for Floor1 room navigation

+## Self-Review: Spec Coverage Check
+
+| Sprint 8-10 requirement | Covered by |
+|-------------------------|-----------|
+| Röntgen mit Slide-Animation | Task 1+2: XRayMachine with 4-state plate animation |
+| Apotheke (alle Medikamente positiv) | Task 3: Pharmacy with VitaminBottle, BandageRoll, SyrupBottle, MedicineBox |
+| Labor | Task 4: Lab with Microscope, TestTubeRack, ReagentBottle, PetriDish |
+| Patientenzimmer | Task 5: PatientRoom with 2 beds, TV, BedsideTable |
+| All rooms accessible via elevator + horizontal nav | Task 6: Full Main.tscn wiring |
+
+**Placeholder scan:** All code blocks complete. No "TBD" or "TODO". ViewerFrame/Viewer nodes referenced in script by node name — both exist in XRayMachine.tscn. ✓
+
+**Type consistency:**
+- `XRayMachine._on_plate_in()` used as signal callback: matches `tween.finished.connect(_on_plate_in)` ✓
+- `VIEWER_LIT_COLOR` / `VIEWER_DARK_COLOR` used in `_on_plate_in()` and `_start_slide_out()` ✓
+- `Plate` node accessed as `Node2D` (not `ColorRect`) — correct, Plate is a Node2D in the scene ✓
+- `Viewer` node accessed as `ColorRect` — correct, Viewer is a ColorRect in the scene ✓

+## Smoke Test Checklist (manual, on device after completion)
+
+- [ ] Elevator from Floor 0 lands at Floor 1 XRay room
+- [ ] "→" navigates Floor 1: XRay → Pharmacy → Lab → PatientRoom and back
+- [ ] Tapping XRayMachine: plate slides out to the right, viewer lights up blue-white, plate slides back, viewer goes dark
+- [ ] Tapping XRayMachine again during animation: nothing happens (state guard)
+- [ ] All medicine objects in Pharmacy bounce when tapped (all positive, no harmful items)
+- [ ] All lab objects in Lab bounce when tapped
+- [ ] TV and BedsideTable in PatientRoom bounce when tapped
+- [ ] Elevator Up from Floor 1 navigates to Floor 2 placeholder
+- [ ] Elevator Down from Floor 1 lands at Floor 0 Reception (room 0)
+- [ ] Bunny character can be dragged to Floor 1 and position is saved
