# Palace Health — Butler Guide

Palace Health is Junwon's personal health tracker. Logs food, exercise, sleep, symptoms, and body metrics by day.

## Data Structure

```
palaces/manglasabang/palaceappsdata/palacehealth/
  2026/
    03/
      20.json       ← one file per day
```

Each day file:

```json
{
  "date": "2026-03-20",
  "dayOfWeek": "Friday",
  "food": [
    { "time": "13:30", "what": "Orange bell pepper", "tags": ["vegetable"] }
  ],
  "exercise": [
    { "time": "09:00", "what": "30 min walk", "tags": ["cardio"] }
  ],
  "sleep": { "bedtime": "23:30", "wakeup": "08:00", "quality": "good", "note": "Slept well" },
  "symptoms": [
    { "time": "11:30", "what": "Right wrist pain", "severity": 2 }
  ],
  "metrics": {
    "weight": 72.5,
    "steps": 8400
  }

```

## Rules

- One file per day. File name = `DD.json`.
- All times are 24h format.
- Entries within each section are in chronological order by `time`.
- `what` is short and direct. Not a paragraph — a line.
- Food tags are optional but helpful for nutrition summaries.
- Severity 1–5: 1 mild/barely noticeable, 3 moderate/affecting activity, 5 severe/disabling.
- Never delete or edit past entries unless Junwon explicitly asks.

## Butler Workflow

1. "I ate a banana" → append to `food`: `{ "time": "<now>", "what": "Banana", "tags": ["fruit"] }`
2. "Went for a run" → append to `exercise`: `{ "time": "<now>", "what": "Run" }`
3. "My knee hurts a bit" → append to `symptoms`: `{ "time": "<now>", "what": "Knee pain", "severity": 2 }`
4. "Slept great, 11pm to 8am" → set `sleep`: `{ "bedtime": "23:00", "wakeup": "08:00", "quality": "good" }`
5. "I weigh 72kg" → set `metrics.weight`: 72
6. If no file exists for today, create it with date and dayOfWeek.
