# DBIS GRU MASTERBOOK VOLUME

## Comprehensive Global Reserve Unit Architecture, Derivatives, Legal Framework, Stress Testing, Multi-Timeline Settlement & Technical Diagrams

This Masterbook unifies all expansions requested for the **Global Reserve Unit (GRU)**, including derivatives, legal issuance standards, stress testing models, multi-reality settlement logic, and technical diagrams. It serves as the authoritative reference for GRU architecture within DBIS.

## 1. GRU OVERVIEW & MONETARY ROLE

The GRU functions as a **multi-asset, metal-anchored, synthetic reserve unit** embedded within DBIS for:

* Sovereign reserves
* Liquidity generation
* Bond systems (Li99PpOsB10 / Li99PpAvB10)
* Commodity/currency cross-settlement
* FX stabilization (via XAU triangulation)
* Multi-reality ledger coherence

---

## 2. GRU STRUCTURE & INDEX FAMILY (LiXAU, LiPMG, LiBMG1–3)

### 2.1 GRU Hierarchy

```
1 M00 GRU = 5 M0 GRU
1 M00 GRU = 25 M1 GRU
1 M00 GRU = x M0 GRU + y M1 GRU (mixed composition)
```

### 2.2 Index System

**LiXAU**: Gold/XAU-based index for GRU valuation
- Base value: 100
- Calculation method: xau_based
- Direct link: 1 GRU M00 = 1 oz XAU

**LiPMG**: Platinum Group Metals index
- Base value: 40
- Calculation method: pgm_based
- Weightings: Platinum (50%), Palladium (30%), Rhodium (20%)

**LiBMG1**: Base Metal Group 1 Index
- Base value: 30
- Calculation method: bmg_weighted
- Weightings: Copper (50%), Nickel (30%), Zinc (20%)

**LiBMG2**: Base Metal Group 2 Index
- Base value: 20
- Calculation method: bmg_weighted
- Weightings: Aluminum (50%), Lead (30%), Tin (20%)

**LiBMG3**: Base Metal Group 3 Index
- Base value: 10
- Calculation method: bmg_weighted
- Weightings: Iron Ore (50%), Manganese (30%), Chromium (20%)

**Already established in Supplement A.**

This Masterbook integrates and expands all index functionalities.

#### Class I — Sovereign-Grade Reserve Instrument
For SCBs only.

#### Class II — Institutional-Grade GRU
Banks, sovereign funds.

#### Class III — Restricted Commercial GRU
Enterprise-grade.

#### Class IV — Observational GRU
Non-settlement synthetic access.

### 4.3 Legal Requirements for Issuance

### 5.2 Multi-Timeline Stress Tests

Integrated with DBIS temporal frameworks:

* t0 (present)
* t−1 to t−12 (retrocausal stress)
* t+1 to t+60 (forward predictive stress)

#### Temporal Stress Condition

```
Temporal_Variance(GRU) = abs( GRU(t+Δ) - GRU(t-Δ) ) > Threshold
```

### 5.3 Quantum Stress Models

* GRU wavefunction collapse simulation
* Quantum arbitrage suppression
