# Patch Implementation Test Results

## Overview
This document shows the expected results for testing the 4 patches implemented in the nutrition system.

## Patch 1 — Reset Daily Tracking

### Expected API Responses

#### POST /api/nutrition/reset-day
```bash
curl -X POST https://saman-app-v5us.onrender.com/api/nutrition/reset-day \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{"date": "2026-03-17"}'
```

**Expected Response:**
```json
{
  "status": "reset",
  "date": "2026-03-17", 
  "reset_at": "2026-03-17T12:34:56.789Z"
}
```

#### GET /api/nutrition/2026-03-17 (after reset)
```bash
curl -X GET https://saman-app-v5us.onrender.com/api/nutrition/2026-03-17 \
  -H "Authorization: Bearer <token>"
```

**Expected Response:**
```json
{
  "date": "2026-03-17",
  "entries": [],  // Empty because all entries were created before reset_at
  "total_calories": 0,
  "total_protein": 0.0,
  "total_carbs": 0.0, 
  "total_fat": 0.0,
  "current_water": 0,
  "water_target": 2000,
  "rollover_calories": 0
}
```

#### Weekly Report (should preserve historical data)
```bash
curl -X GET "https://saman-app-v5us.onrender.com/api/nutrition/report/weekly?start_date=2026-03-16" \
  -H "Authorization: Bearer <token>"
```

**Expected Response:** Day 2026-03-17 should still show original calories (e.g., 1250) because weekly report reads directly from collection without reset filter.

## Patch 2 — Calorie Budget Rollover

### Expected API Response

#### GET /api/nutrition/2026-03-17
Should include new field `rollover_calories`:

```json
{
  "date": "2026-03-17",
  "entries": [...],
  "total_calories": 800,
  "total_protein": 45.2,
  "total_carbs": 120.5,
  "total_fat": 25.8,
  "current_water": 1500,
  "water_target": 2000,
  "rollover_calories": 150  // NEW: 50% of yesterday's deficit
}
```

**Calculation Example:**
- Yesterday's target: 2000 kcal
- Yesterday's actual: 1700 kcal  
- Deficit: 2000 - 1700 = 300 kcal
- Rollover: 300 * 0.5 = 150 kcal

## Patch 3 — Meal Swap

### Expected API Response

#### PUT /api/nutrition/logs/{log_id}/swap
```bash
curl -X PUT https://saman-app-v5us.onrender.com/api/nutrition/logs/607e4fc8-5b6b-4e8b-9a8a-5b6b4e8b9a8a/swap \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "log_id": "607e4fc8-5b6b-4e8b-9a8a-5b6b4e8b9a8a",
    "food_index": 0,
    "replacement_food_id": "607e4fc8-5b6b-4e8b-9a8a-5b6b4e8b9a8b"
  }'
```

**Expected Response:**
```json
{
  "id": "607e4fc8-5b6b-4e8b-9a8a-5b6b4e8b9a8a",
  "message": "Meal swapped",
  "old_food": "Pizza",
  "new_food": "Chicken Breast",
  "new_calories": 250
}
```

**Behavior:**
- Finds original food in the log
- Looks up replacement food (user_foods first, then global foods)
- Scales nutrition values based on original weight_grams
- Updates the log with new food and recalculated total calories

## Patch 4 — Water Reminder Badge (Flutter-only)

### Expected UI Behavior

This patch only affects the Flutter frontend, no API changes.

**Before 3 PM with < 50% water intake:**
- Normal blue water icon
- No warning badge
- Blue progress bar

**After 3 PM with < 50% water intake:**
- Orange water icon
- Warning badge: "⚠️ Uống thêm nước!"
- Orange border around container
- Orange progress bar

**Example UI:**
```
Water Intake ⚠️ Uống thêm nước!
750 / 2000 ml
[Orange progress bar at 37.5%]
```
