**TASK: Complete Currency Rebranding - ThreeFold Credit (TFC) → Mycelium Credit (MC)**

**Objective:** Systematically replace all instances of "ThreeFold Credit", "TFC", and related currency terminology with "Mycelium Credit" and "MC" throughout the Project Mycelium marketplace repository, implementing the new currency system with 1 MC = 1 USD base rate.

**Requirements:**
1. **Analyze Current Usage:** Use grep to find ALL instances of "TFC", "ThreeFold Credit", "TF Credit", "tfp", "TFP", "credits_usd", currency symbols, and wallet references across the entire codebase.

2. **Categorize by File Type:** Backend (controllers, services, models), Frontend (views, JS), Tests, Docs/Specs, Configuration

3. **Develop Replacement Strategy:** 
   - **Backend (Code & Logic):**
     - "TFC" → "MC"
     - "ThreeFold Credit" → "Mycelium Credit" 
     - "TF Credit" → "Mycelium Credit"
     - "tfp" → "mc" (variable names)
     - "TFP" → "MC" (constants/enums)
     - `credits_usd` → `credits_mc` (if needed)
     - Currency calculation logic (maintain 1:1 USD rate)
   - **Frontend (Display text):**
     - "ThreeFold Credit" → "Mycelium Credit"
     - "TFC" → "MC" 
     - Currency symbols and wallet displays
     - Balance and transaction displays
   - **Configuration & Settings:**
     - Default currency preferences
     - Exchange rate configurations
     - Currency service initialization

4. **Execute Systematically:** Start with backend currency service, then controllers, then frontend, then docs

5. **Verify Thoroughly:** Use multiple verification commands:
   - `grep -r "TFC" src/ --include="*.rs" --include="*.html" --include="*.js"`
   - `grep -r "ThreeFold Credit" src/ --include="*.rs" --include="*.html" --include="*.js"`
   - `grep -r "TF Credit" src/ --include="*.rs" --include="*.html" --include="*.js"`
   - `grep -r "tfp" src/ --include="*.rs" --include="*.html" --include="*.js"`
   - `grep -r "TFP" src/ --include="*.rs" --include="*.html" --include="*.js"`

**Key Areas to Focus:**
- Currency service and exchange rate logic
- Wallet components and balance displays  
- Transaction processing and records
- Dashboard financial displays and charts
- Marketplace pricing and payment flows
- User settings and currency preferences
- API responses with currency data
- Database references and user data
- Documentation and help text
- Legal terms and agreements
- Test files and mock data
- Configuration files and settings

**Implementation Strategy:**
1. **Currency Service Foundation** - Update core currency logic and rates
2. **Backend Controllers** - Update API endpoints and data processing  
3. **Frontend Templates** - Update all user-facing currency displays
4. **JavaScript Logic** - Update client-side currency handling
5. **Documentation** - Update specs, docs, and legal terms
6. **Configuration** - Update default settings and preferences
7. **Testing** - Update test data and verify functionality

**Critical Considerations:**
- **Maintain 1 MC = 1 USD rate** - Ensure pricing calculations remain accurate
- **User data migration** - Handle existing user balances and transaction history
- **API compatibility** - Ensure external integrations continue to work
- **Currency preferences** - Implement proper MC/USD/AED display options
- **Backward compatibility** - Plan for any legacy TFC references

**Expected File Updates:**
- Currency service: `src/services/currency.rs` or similar
- Controllers: `src/controllers/wallet.rs`, `src/controllers/dashboard.rs`
- Models: `src/models/user.rs` (wallet/balance fields)
- Frontend: All wallet, dashboard, and marketplace templates
- JavaScript: Currency formatting and calculation logic
- Tests: Update mock data and currency test cases
- Docs: Update specs and user documentation
- Legal: Update terms of service and agreements

**Success Criteria:**
- Zero remaining "TFC"/"ThreeFold Credit" references in codebase
- All currency displays show "MC"/"Mycelium Credit"
- Currency calculations maintain accuracy (1 MC = 1 USD)
- Wallet and balance displays updated consistently
- User preferences support MC/USD/AED display options
- All financial flows (purchase, balance, transactions) work correctly
- Documentation and legal terms updated
- Tests pass with new currency terminology
- No breaking changes to existing user data or API contracts

**Verification Commands:**
After implementation, run these verification commands to ensure complete migration:
```bash
grep -r "TFC" src/ --include="*.rs" --include="*.html" --include="*.js"          # Should return 0 results
grep -r "ThreeFold Credit" src/ --include="*.rs" --include="*.html" --include="*.js"  # Should return 0 results
grep -r "TF Credit" src/ --include="*.rs" --include="*.html" --include="*.js"   # Should return 0 results
grep -r "\btfp\b" src/ --include="*.rs" --include="*.html" --include="*.js"     # Should return 0 results (word boundaries)
grep -r "\bTFP\b" src/ --include="*.rs" --include="*.html" --include="*.js"     # Should return 0 results (word boundaries)

# Verify successful replacements:
grep -r "MC" src/ --include="*.rs" --include="*.html" --include="*.js"          # Should show currency references
grep -r "Mycelium Credit" src/ --include="*.rs" --include="*.html" --include="*.js"  # Should show display text
```

**Important Notes:**
- **Systematic Approach:** Follow the same methodical process used for Application Solutions → Agentic Apps
- **Currency Service Priority:** Start with the core currency service to establish the foundation
- **User Experience Focus:** Ensure all user-facing displays are consistent and clear
- **Financial Accuracy:** Double-check all calculations and exchange rate logic
- **Data Integrity:** Preserve existing user financial data during transition
- **Testing Critical:** Financial systems require thorough testing before deployment

**Expected Outcome:** Complete, consistent rebranding from "ThreeFold Credit (TFC)" to "Mycelium Credit (MC)" with proper currency system implementation, maintaining the same quality and thoroughness as previous rebrandings.
