+# Sprint 16 — Snap-Point System 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 SnapPoint nodes to all furniture in all 12 rooms so characters can snap into sitting/lying poses when released near a piece of furniture.
+
+**Architecture:** Each room `.tscn` gets one `ext_resource` entry for `snap_point.gd` and one `[node]` entry per snap position. SnapPoints are direct children of the room node (not children of ColorRect furniture, since ColorRects have no Node2D hierarchy). All SnapPoints auto-register in the `"snap_points"` group via `_ready()`. No new GDScript is written — this sprint is purely scene data.
+
+**Tech Stack:** Godot 4.6.2, `.tscn` text format, GUT v9.6.0 (TDD), headless runner.
+
+**GDD Reference:** `docs/game-design.md` — Kapitel 2 (Raum-Übersicht) + Kapitel 5.1 (Snap-Point System).
+
+**Headless runner:**
+```
+"F:/Development/_tools/Godot_v4.6.2-stable_win64/Godot_v4.6.2-stable_win64.exe" --headless -s res://addons/gut/gut_cmdln.gd -gdir=res://test/ -gexit 2>&1
+```
+
+**Existing tests must stay green:** 90 tests passing before this sprint starts.

+
+## How to add a SnapPoint to a .tscn
+
+### 1. Increment `load_steps` in the header by 1
+
+```
+[gd_scene load_steps=3 format=3 ...]   ← was 2
+```
+
+### 2. Add `ext_resource` for snap_point.gd after the last existing `ext_resource` line
+
+For rooms with currently 1 ext_resource (InteractiveObject only), use id `"2_snap"`:
+```
+[ext_resource type="Script" path="res://scripts/objects/snap_point.gd" id="2_snap"]
+```
+
+For rooms with currently 2 ext_resources, use id `"3_snap"`:
+```
+[ext_resource type="Script" path="res://scripts/objects/snap_point.gd" id="3_snap"]
+```
+
+For GardenParty (3 ext_resources), use id `"4_snap"`:
+```
+[ext_resource type="Script" path="res://scripts/objects/snap_point.gd" id="4_snap"]
+```
+
+### 3. Append node entries at the end of the file
+
+Sitting (default pose, no need to set pose or baby_only):
+```
+[node name="SnapBenchLeft1" type="Node2D" parent="."]
+position = Vector2(150, 555)
+script = ExtResource("2_snap")
+```
+
+Lying (must set pose):
+```
+[node name="SnapExamTable" type="Node2D" parent="."]
+position = Vector2(640, 480)
+script = ExtResource("2_snap")
+pose = "lying"
+```
+
+Lying + baby only:
+```
+[node name="SnapCradle1" type="Node2D" parent="."]
+position = Vector2(340, 240)
+script = ExtResource("3_snap")
+pose = "lying"
+baby_only = true
+```
+
+---
+
+## Helper: how tests count SnapPoints in a room
+
+```gdscript
+func _count_snaps(room: Node2D) -> int:
+    var count: int = 0
+    for child: Node in room.get_children():
+        if child is SnapPoint:

+
+### Step 2: Run tests — verify 9 new tests FAIL
+
+Expected: 9 failures. 106 existing pass.
+
+### Step 3: Edit `scenes/rooms/floor2/Ultrasound.tscn`
+
+Current header: `load_steps=3` (has UltrasoundMachine). Change to `load_steps=4`.
+
+Add after last ext_resource:
+```
+[ext_resource type="Script" path="res://scripts/objects/snap_point.gd" id="3_snap"]
+```
+
+Append:
+```
+[node name="SnapExamTable" type="Node2D" parent="."]
+position = Vector2(470, 480)
+script = ExtResource("3_snap")
+pose = "lying"
+```
+
+### Step 4: Edit `scenes/rooms/floor2/DeliveryRoom.tscn`
+
+Current header: `load_steps=3` (has DeliveryBed). Change to `load_steps=4`.
+
+Add after last ext_resource:
+```
+[ext_resource type="Script" path="res://scripts/objects/snap_point.gd" id="3_snap"]
+```
+
+Append:
+```
+[node name="SnapDeliveryBed" type="Node2D" parent="."]
+position = Vector2(540, 480)
+script = ExtResource("3_snap")
+pose = "lying"
+```
+
+### Step 5: Edit `scenes/rooms/floor2/Nursery.tscn`
+
+Current header: `load_steps=3` (has Cradle). Change to `load_steps=4`.
+
+Add after last ext_resource:
+```
+[ext_resource type="Script" path="res://scripts/objects/snap_point.gd" id="3_snap"]
+```
+
+Append:
+```
+[node name="SnapCradle1" type="Node2D" parent="."]
+position = Vector2(340, 240)
+script = ExtResource("3_snap")
+pose = "lying"
+baby_only = true

+position = Vector2(600, 240)
+script = ExtResource("3_snap")
+pose = "lying"
+baby_only = true
+
+[node name="SnapCradle3" type="Node2D" parent="."]
+position = Vector2(860, 240)
+script = ExtResource("3_snap")
+pose = "lying"
+baby_only = true
+```
+
+### Step 6: Edit `scenes/rooms/home/GardenParty.tscn`
+
+Current header: `load_steps=4` (has GiftBox, TeaPot, HomeButton). Change to `load_steps=5`.
+
+Add after the last ext_resource (HomeButton):
+```
+[ext_resource type="Script" path="res://scripts/objects/snap_point.gd" id="4_snap"]
+```
+
+Append:
+```
+[node name="SnapTableLeft" type="Node2D" parent="."]
+position = Vector2(530, 455)
+script = ExtResource("4_snap")
+
+[node name="SnapTableRight" type="Node2D" parent="."]
+position = Vector2(750, 455)
+script = ExtResource("4_snap")
+```
+
+### Step 7: Run tests — verify 9 new tests PASS (115 total)
+
+Run `--headless --import` first, then the test runner.
+
+Expected: 115/115 passed.
+
+### Step 8: Commit
+
+```bash
+cd "F:/Development/_gameDev/Cozypaw-Hospital/.worktrees/sprint-16-snap-points"
+git add scenes/rooms/floor2/Ultrasound.tscn scenes/rooms/floor2/DeliveryRoom.tscn
