+# Dependency Analysis and Module Organization
+
+## Overview
+
+This document outlines the dependency structure and module organization implemented to resolve Issue #316: Missing Module Organization.
+
+## Dependency Graph
+
+```
+gathera-common (Base Layer)
+├── No external dependencies
+└── Provides: types, errors, utils, gas_testing
+
+ticket_contract
+├── gathera-common
+└── Provides: soulbound ticket functionality
+
+escrow_contract  
+├── gathera-common
+└── Provides: escrow services
+
+multisig_wallet_contract
+├── gathera-common
+└── Provides: multi-signature wallet
+
+contracts (Integration Layer)
+├── gathera-common
+├── ticket_contract
+├── escrow_contract
+├── multisig_wallet_contract
+└── Provides: cross-contract orchestration
+
+test (Testing Layer)
+├── gathera-common
+├── ticket_contract
+├── escrow_contract
+└── Provides: comprehensive testing utilities
+```
+
+## Circular Dependency Resolution
+
+### Before (Problematic)
+```
+ticket_contract ↔ escrow_contract ↔ multisig_wallet_contract
+```
+
+### After (Resolved)
+```
+gathera-common → ticket_contract
+gathera-common → escrow_contract  
+gathera-common → multisig_wallet_contract
+all contracts → contracts (integration)
+all contracts → test
+```
+
+## Module Boundaries
+
+### 1. **gathera-common** (Foundation)
+- **Purpose**: Base utilities and shared types
+- **Dependencies**: None
+- **Provides**: Core functionality for all other modules
+- **Boundary**: No contract-specific logic
+
+### 2. **Individual Contracts** (Business Logic)
+- **Purpose**: Specific contract functionality
+- **Dependencies**: Only gathera-common
+- **Provides**: Single-responsibility contract implementations
+- **Boundary**: No cross-contract dependencies
+
+### 3. **contracts** (Integration)
+- **Purpose**: Cross-contract workflows and orchestration
+- **Dependencies**: All individual contracts
+- **Provides**: Unified interfaces and workflows
+- **Boundary**: No contract implementation details
+
+### 4. **test** (Testing)
+- **Purpose**: Comprehensive testing and benchmarking
+- **Dependencies**: All contracts
+- **Provides**: Testing utilities and benchmarks
+- **Boundary**: No production code
+
+## Workspace Configuration
+
+### Root Cargo.toml
+```toml
+[workspace]
+resolver = "2"
+members = [
+    "common",
+    "ticket_contract", 
+    "escrow_contract",
+    "multisig_wallet_contract",
+    "contracts",
+    "test"
+]
+
+[workspace.dependencies]
+soroban-sdk = "23.5.2"
+```
+
+### Benefits of Workspace Structure
+1. **Consistent Dependencies**: All crates use same versions
+2. **Simplified Builds**: Single command builds entire workspace
+3. **Shared Configuration**: Common optimization settings
+4. **Easy Testing**: Run tests across entire workspace
+
+## Module Documentation Standards
+
+### 1. **Module-Level Documentation**
+- Purpose and responsibility
+- Key features and capabilities
+- Dependencies and what they provide
+- Usage examples
+
+### 2. **Function-Level Documentation**
+- Purpose and behavior
+- Parameters and their types
+- Return values and error conditions
+- Usage examples and edge cases
+
+### 3. **Type-Level Documentation**
+- Structure purpose and fields
+- Invariants and constraints
+- Usage patterns and examples
+
+## Code Organization Principles
+
+### 1. **Single Responsibility**
+Each module has one clear purpose and responsibility.
+
+### 2. **Dependency Direction**
+Dependencies flow in one direction: common → contracts → integration → test
+
+### 3. **Interface Segregation**
+Modules expose minimal, well-defined interfaces.
+
+### 4. **Common Code Centralization**
+Shared functionality is centralized in gathera-common.

+## Benefits of This Organization
+
+### 1. **Maintainability**
+- Clear module boundaries make code easier to understand
+- Shared utilities reduce duplication
+- Consistent structure across all contracts
+
+### 2. **Testability**
+- Isolated modules are easier to test
+- Shared testing utilities improve test coverage
+- Clear dependency chains simplify testing
+
+### 3. **Extensibility**
+- New contracts can follow established patterns
+- Common functionality is easily reusable
+- Integration layer handles complex workflows
+
+### 4. **Build Efficiency**
+- Workspace builds all modules together
+- Shared dependencies reduce compile time
+- Consistent optimization settings
+
+## Migration Strategy
+
+### Phase 1: Foundation
+- ✅ Create gathera-common with base utilities
+- ✅ Set up workspace configuration
+- ✅ Establish module boundaries
+
+### Phase 2: Contract Refactoring
+- ✅ Create individual contract crates
+- ✅ Implement contract interfaces
+- ✅ Add comprehensive documentation
+
+### Phase 3: Integration
+- ✅ Create integration layer
+- ✅ Implement cross-contract workflows
+- ✅ Add deployment utilities
+
+### Phase 4: Testing & Validation
+- ✅ Comprehensive testing utilities
+- ⏳ Build and dependency validation
+- ⏳ CI/CD pipeline updates
+
