+# Sprint 14 — Garden Party 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:** Complete the GardenParty scene with GiftBox auto-reset, Balloon pop/respawn, Cake cut/reset, and chair snap points for characters.
+
+**Architecture:** Three independent state-machine objects (`gift_box.gd` extended, `balloon.gd` new, `cake.gd` new) following the existing project pattern — each with a `State` enum, tween-driven animations, and `_on_X_complete()` callbacks testable without tweens. `GardenParty.tscn` is updated to wire balloon scripts and add the Cake and chair nodes. No new autoloads or base classes.
+
+**Tech Stack:** GDScript 4 (static types), GUT v9.6.0, Godot 4.6.2.
+

+
+### Task 1: GiftBox RESETTING state
+
+**Files:**
+- Modify: `scripts/objects/gift_box.gd`
+- Modify: `test/unit/test_gift_box.gd`
+
+The `OPEN` state is removed. `RESETTING` replaces it: gift fades in, waits 3 s, then the lid closes and the box resets.
+
+- [ ] **Step 1: Update test file**
+
+Replace the full contents of `test/unit/test_gift_box.gd` with:
+
+```gdscript

+	_box._input(event)
+	assert_eq(_box._state, GiftBox.State.RESETTING)
+
+
+func test_tap_outside_hitbox_does_not_open() -> void:
+	var event: InputEventScreenTouch = InputEventScreenTouch.new()
+	event.pressed = true
+	event.position = _box.global_position + Vector2(200.0, 200.0)
+	_box._input(event)

+

+# Sprint 14 — Garden Party Spec
+
+## Goal
+
+Make the GardenParty scene a fully playable sandbox room with three interactive objects
+(GiftBox auto-reset, Balloon pop/respawn, Cake cut/reset) and character snap-to-chair
+at the party table.
+
+---
+
+## Scope
+
+**In scope:**
+- `gift_box.gd`: add `RESETTING` state (auto-reset 3 s after opening)
+- `balloon.gd`: new script — tap to pop, auto-respawn after 5 s
+- `cake.gd`: new script — tap to cut slice, auto-reset after 3 s
+- `GardenParty.tscn`: replace GiftBox3 with Cake, add Cake node structure, add chair
+  ColorRects under snap points, attach balloon.gd to existing Balloon nodes
+- Tests: extend `test_gift_box.gd`, add `test_balloon.gd`, add `test_cake.gd`
+
+**Out of scope:**
+- New SFX keys (reuse `object_tap` for all three objects)
+- Navigation changes (HomeButtonToGarden and HomeButtonReturn already wired)
+- Additional characters beyond Bunny1 already in Main.tscn
+
+---
+
+## Object Mechanics
+
+### GiftBox — RESETTING state
+
+New state added to the existing `State` enum:
+
+```
+CLOSED → OPENING → RESETTING → CLOSED
+```
+
+- `_on_lid_opened()`: state → `RESETTING`, gift fades in (existing tween), inline 3 s
+  tween interval runs in parallel → `_start_close_lid()`
+- `_start_close_lid()`: lid tweens back (fade-in alpha 0→1, slide y back to 0) →
+  `_on_reset_complete()`
+- `_on_reset_complete()`: state → `CLOSED`
+- `OPEN` state removed — `RESETTING` covers "gift visible + waiting"
+- New internal methods: `_start_close_lid()`, `_on_reset_complete()`
+- Constant: `RESET_DELAY: float = 3.0`
+
+### Balloon
+
+New file: `scripts/objects/balloon.gd`  
+New scene attachment: `balloon.gd` attached to existing `Balloon1` / `Balloon2` nodes in
+`GardenParty.tscn`.
+
+```
+IDLE → POPPING → POPPED → RESPAWNING → IDLE
+```
+
+State transitions:
+- Touch input on balloon while `IDLE` → `_start_pop()`
+- `_start_pop()`: `AudioManager.play_sfx("object_tap")`, state → `POPPING`, scale tween to
+  `Vector2.ZERO` (0.15 s, EASE_IN, TRANS_BACK) → `_on_pop_complete()`
+- `_on_pop_complete()`: state → `POPPED`, starts 5 s tween interval → `_start_respawn()`
+- `_start_respawn()`: state → `RESPAWNING`, scale tween to `Vector2.ONE` (0.3 s, EASE_OUT,
+  TRANS_BACK) → `_on_respawn_complete()`
+- `_on_respawn_complete()`: state → `IDLE`
+
+Input: `_input(event)` — same touch-rect pattern as GiftBox, half-size 20 px (balloon is
+small).
+
+Constants: `POP_DURATION`, `RESPAWN_DURATION`, `RESPAWN_DELAY`.
+
+### Cake
+
+New file: `scripts/objects/cake.gd`  
+New node structure in `GardenParty.tscn` (replaces GiftBox3 at x=820, y=464):
+
+```
+Cake (Node2D, cake.gd)
+├── Base (ColorRect, ~80×40 px, warm brown)
+└── Slice (ColorRect, ~30×40 px, slightly offset + rotated, lighter brown)
+```
+
+```
+WHOLE → CUTTING → CUT → RESETTING → WHOLE
+```
+
+State transitions:
+- Touch input on Cake while `WHOLE` → `_start_cutting()`
+- `_start_cutting()`: `AudioManager.play_sfx("object_tap")`, state → `CUTTING`,
+  tween `Slice.modulate.a` 1→0 (0.3 s, EASE_OUT) → `_on_cut_complete()`
+- `_on_cut_complete()`: state → `CUT`, 3 s tween interval → `_start_reset()`
+- `_start_reset()`: state → `RESETTING`, tween `Slice.modulate.a` 0→1 (0.3 s, EASE_IN)
+  → `_on_reset_complete()`
+- `_on_reset_complete()`: state → `WHOLE`
+
+Input: touch rect `BUTTON_HALF_WIDTH = 40`, `BUTTON_HALF_HEIGHT = 20`.
+
+Constants: `CUT_DURATION`, `RESET_DELAY = 3.0`, `RESET_DURATION`.
+
+---
+
+## Scene Changes (GardenParty.tscn)
+
+| Change | Detail |
+|---|---|
+| Remove `GiftBox3` | Was at position Vector2(820, 464) |
+| Add `Cake` | Node2D at Vector2(820, 464), `cake.gd`, child nodes Base + Slice |
+| Attach `balloon.gd` | To existing `Balloon1` and `Balloon2` ColorRect nodes |
+| Add `ChairLeft` | ColorRect ~60×20 px, brown, under `SnapTableLeft` (x=530, y=480) |
+| Add `ChairRight` | ColorRect ~60×20 px, brown, under `SnapTableRight` (x=750, y=480) |
+
+Navigation and snap-point logic unchanged.
+
+---
+
+## Tests
+
+### `test_gift_box.gd` (extend existing)
+
+| Test | Assertion |
+|---|---|
+| `test_state_becomes_resetting_after_lid_opened` | Call `_on_lid_opened()` → state == `State.RESETTING` |
+| `test_state_becomes_closed_after_reset_complete` | Call `_on_reset_complete()` → state == `State.CLOSED` |
+
+### `test_balloon.gd` (new, extends GutTest)
+
+| Test | Assertion |
+|---|---|

+### `test_cake.gd` (new, extends GutTest)
+
+| Test | Assertion |
+|---|---|
+| `test_initial_state_is_whole` | `state == State.WHOLE` |
+| `test_start_cutting_sets_cutting` | Call `_start_cutting()` → `state == State.CUTTING` |
+| `test_on_cut_complete_sets_cut` | Call `_on_cut_complete()` → `state == State.CUT` |
+| `test_on_reset_complete_sets_whole` | Call `_on_reset_complete()` → `state == State.WHOLE` |

+
+## Architecture Notes
+
+- All three objects follow the same state-machine pattern as existing objects (`cradle.gd`,
+  `gift_box.gd`, etc.) — no new abstractions.
+- Tween-based animations are not unit-tested (visual only). State transitions triggered by
+  `tween.finished` callbacks are tested by calling the callbacks directly.
+- `AudioServer.get_driver_name() == "Dummy"` guard is already in `AudioManager.play_sfx()`
+  — no additional guard needed in new scripts.
+- `balloon.gd` scales the Node2D itself (no child sprite node needed at placeholder stage).
