## 1. Core Mathematical Formulas & Gold Market Rules

### A. Gold Workmanship (Masnaia) & Fraud Calculation:
- **Formula:** `Total Masnaia = Total Invoice Amount - (Total Weight in Grams × Raw Gold Gram Price Today)`.
- **Per Gram Masnaia:** `Total Masnaia ÷ Total Weight in Grams`.
- **Official Warning Thresholds (Egypt Market):**
  - BTC Bullion (10g+ 24k): Standard Masnaia is 65-80 EGP/g. Exceeding 90 EGP/g indicates overcharging.
  - Standard 21k Jewelry (Bangles/Rings): Standard Masnaia is 80-140 EGP/g. Exceeding 160 EGP/g indicates overcharging.
  - 18k Italian Jewelry: Standard Masnaia is 140-230 EGP/g. Exceeding 260 EGP/g indicates overcharging.

### B. Egypt 14% Value-Added Tax (VAT) Law on Gold:
- **Official Tax Authority Protocol:** The 14% VAT is strictly charged **ONLY on the workmanship fee (Masnaia)**, NEVER on the raw gold base value.
- **Formula:** `VAT Amount = Total Workmanship (Masnaia) × 0.14`.
- Raw gold is completely tax-exempt under Egyptian law.

### C. Official BTC Bullion Cashback System (Egypt):
- Cashback is a legally mandated refund returned to the buyer upon reselling intact, packaged bullion:
  - 1 Gram BTC Bullion: 45 EGP cashback.
  - 5 Grams BTC Bullion: 35 EGP per gram.
  - 10g & 20g BTC Bullion: 32 EGP per gram.
  - 31.1g (1 Troy Oz), 50g & 100g BTC: 28 to 30 EGP per gram.
  - BTC Gold Pound (8g, 21k): 25 EGP per gram (200 EGP total).

### D. Weights & Karat Equivalencies:
- `1 Troy Ounce (أونصة تروية) = 31.1035 grams of 24k gold (999.9 purity)`.
- `1 Gold Pound (جنيه ذهب) = 8.000 grams of 21k gold (875 purity)`.
- `Half Pound (نصف جنيه ذهب) = 4.000 grams of 21k gold`.
- `Quarter Pound (ربع جنيه ذهب) = 2.000 grams of 21k gold`.
- `5 Gold Pounds (خمسة جنيهات ذهب) = 40.000 grams of 21k gold`.

### E. Islamic Gold Zakat Calculation (زكاة الذهب):
- **Nisab Threshold (النصاب الشرعي):** 85 grams of 24k pure gold (or 97.14g of 21k, or 113.33g of 18k).
- **Zakat Rate:** 2.5% (1/40th) of total market value once held for one full lunar year (Hawl).
- **Formula:** `Total Value in EGP × 0.025`.
