-# React + TypeScript + Vite
+# ISO-20022 Combo Flow
 
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+A visual workflow builder for composing multi-step financial transactions that combine ISO-20022 banking messages with DLT (Distributed Ledger Technology) operations. Think of it as combining Venmo, your bank, and a crypto exchange into one easy-to-use interface.
 
-Currently, two official plugins are available:
+## 🎯 Overview
 
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
+This system enables users to build complex financial workflows by:
+- Dragging and dropping financial steps (borrow, swap, repay, pay)
+- Combining DeFi protocols with traditional banking rails
+- Executing multi-step transactions atomically using 2PC (Two-Phase Commit)
+- Ensuring compliance with LEI/DID/KYC/AML requirements
+- Providing real-time execution monitoring and audit trails
 
-## React Compiler
+## 🚀 Deployment Models
 
-The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+The system supports three deployment models:
 
-## Expanding the ESLint configuration
+- **Web App (Hosted)**: For approved parties (enterprise clients, financial institutions)
+  - Azure AD authentication, RBAC, IP whitelisting
+  - Full compliance features and audit logs
+  
+- **PWA (Mobile)**: Progressive Web App for mobile users
+  - Offline support, push notifications, installable
+  - Same backend with mobile-optimized UI
+  
+- **DApp (Public)**: Decentralized app for general public
+  - Wallet-based authentication (MetaMask, WalletConnect)
+  - Open access, public plan templates
 
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+See [Deployment Architecture](./docs/DEPLOYMENT_ARCHITECTURE.md) for details.
 
-```js
-export default defineConfig([
-  globalIgnores(['dist']),

+## 🏗️ Architecture
 
-      // Remove tseslint.configs.recommended and replace with this
-      tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules

+# ADR-001: Architecture Decisions
+
+## Status
+Accepted
+
+## Context
+ISO-20022 Combo Flow system requires decisions on architecture patterns, technology choices, and design principles.
+
+## Decisions
+
+### 1. Two-Phase Commit (2PC) Pattern
+**Decision**: Use 2PC for atomic execution across DLT and banking rails.
+
+**Rationale**:
+- Ensures atomicity across heterogeneous systems
+- Provides rollback capability
+- Industry standard for distributed transactions
+
+### 2. PostgreSQL for Persistence
+**Decision**: Use PostgreSQL as primary database.
+
+**Rationale**:
+- ACID compliance required for financial transactions
+- JSONB support for flexible plan storage
+- Strong ecosystem and tooling
+
+### 3. Redis for Caching
+**Decision**: Use Redis for caching and session management.
+
+**Rationale**:
+- High performance
+- Pub/sub support for real-time updates
+- Widely supported
+
+### 4. Smart Contract Architecture
+**Decision**: Separate handler, registry, and adapter contracts.
+
+**Rationale**:
+- Modularity and upgradeability
+- Security isolation
+- Easier testing and auditing
+
+### 5. Next.js for Frontend
+**Decision**: Use Next.js 14 with App Router.
+
+**Rationale**:
+- Server-side rendering for performance
+- Built-in API routes
+- Excellent developer experience

+# Answers to Your Questions
+
+## 1. Why is no content appearing for the frontend?
+
+### Root Cause
+The Next.js dev server is running but requests are timing out. This is likely due to:
+- Next.js still compiling on first load
+- Missing environment variables
+- Provider initialization issues
+- Browser cache issues
+
+### Quick Fix
+
+**Option 1: Use the fix script**
+```powershell
+.\scripts\fix-frontend.ps1
+```
+
+**Option 2: Manual fix**
+```powershell
+# 1. Stop webapp
+Get-Process node | Where-Object { (Get-NetTCPConnection -OwningProcess $_.Id).LocalPort -eq 3000 } | Stop-Process -Force
+
+# 2. Clear cache
+cd webapp
+Remove-Item -Recurse -Force .next -ErrorAction SilentlyContinue
+
+# 3. Create .env.local
+@"
+NEXT_PUBLIC_ORCH_URL=http://localhost:8080
+NEXTAUTH_SECRET=dev-secret-change-in-production-min-32-chars
+"@ | Out-File -FilePath .env.local
+
+# 4. Restart
+npm run dev
+```
+
+**Option 3: Check browser console**
+- Open http://localhost:3000
+- Press F12 to open DevTools
+- Check Console tab for errors
+- Check Network tab for failed requests
+
+### Expected Behavior
+- First load: 10-30 seconds (Next.js compilation)
+- Subsequent loads: < 2 seconds
+- You should see: Dashboard with "No plans yet" message
+
+### If Still Not Working
+1. Check terminal where `npm run dev` is running for errors
+2. Verify port 3000 is not blocked by firewall
+3. Try accessing from different browser
+4. Check if Tailwind CSS is compiling (look for `.next` directory)
+
+---
+
+## 2. Local Database vs Azure Deployment?
+
+### Recommendation: **Start Local, Deploy to Azure**
+
+### For Development: Use Local PostgreSQL
+
+**Why:**
+- ✅ Free
+- ✅ Fast setup (5 minutes)
+- ✅ Easy to reset/clear data
+- ✅ Works offline
+- ✅ No Azure costs during development
+
+**Setup:**
+```powershell
+# Using Docker (easiest)
+docker run --name combo-postgres `
+  -e POSTGRES_PASSWORD=postgres `
+  -e POSTGRES_DB=comboflow `
+  -p 5432:5432 `
+  -d postgres:15
+
+# Update orchestrator/.env
+DATABASE_URL=postgresql://postgres:postgres@localhost:5432/comboflow
+RUN_MIGRATIONS=true
+
+# Run migrations
+cd orchestrator
+npm run migrate
+```
+
+### For Production: Use Azure Database
+
+**Why:**
+- ✅ Managed service (no maintenance)
+- ✅ Automatic backups
+- ✅ High availability
+- ✅ Scalable
+- ✅ Integrated with Azure services
+- ✅ Security compliance
+
+**Setup:**
+See `docs/DATABASE_OPTIONS.md` for detailed Azure setup instructions.
+
+### Migration Path
+1. **Now**: Develop with local PostgreSQL
+2. **Staging**: Create Azure database for testing
+3. **Production**: Migrate to Azure Database for PostgreSQL
+
+---
+
+## 3. Can we have Web App, PWA, and DApp versions?
+
+### ✅ YES! All Three Are Possible
+
+The architecture supports all three deployment models:
+
+### 1. Web App (Hosted Product for Approved Parties)
+- **Target**: Enterprise clients, financial institutions
+- **Auth**: Azure AD / Entra ID
+- **Access**: RBAC, IP whitelisting
+- **Hosting**: Azure App Service
+- **Features**: Full compliance, audit logs, enterprise features
+
+### 2. PWA (Progressive Web App - Mobile)
+- **Target**: Mobile users (iOS/Android)
+- **Auth**: Azure AD + Biometric
+- **Features**: Offline support, push notifications, installable
+- **Hosting**: Same backend, CDN for assets
+- **Deployment**: Add PWA config to existing Next.js app
+
+### 3. DApp (Decentralized App - General Public)
+- **Target**: General public, Web3 users
+- **Auth**: Wallet-based (MetaMask, WalletConnect)
+- **Access**: Open to all (no approval)
+- **Hosting**: IPFS or traditional hosting
+- **Features**: Public plan templates, community features
+
+### Implementation Strategy
+
+**Phase 1: Web App (Current)**
+- Already implemented
+- Add Azure AD authentication
+- Deploy to Azure App Service
+
+**Phase 2: PWA (Add Mobile Support)**
+- Add `manifest.json`
+- Implement service worker
+- Mobile-optimized UI
+- Same backend, different UI
+
+**Phase 3: DApp (Public Version)**
+- Create public routes (`/dapp/*`)
+- Wallet authentication
+- Public API endpoints
+- Deploy to IPFS or public hosting
+
+### Code Structure
+```
+webapp/
+├── src/
+│   ├── app/
+│   │   ├── (webapp)/     # Approved parties
+│   │   ├── (pwa)/        # Mobile version
+│   │   └── (dapp)/       # Public version
+│   └── components/
+│       ├── webapp/       # Enterprise components
+│       ├── pwa/          # Mobile components
+│       └── dapp/         # Public components
+```
+
+### Shared Backend
+- Same orchestrator API
+- Multi-auth middleware (Azure AD + Wallet)
+- Route-based access control
+- Different rate limits per user type
+
+---
+
+## Next Steps
+
+### Immediate (Frontend Fix)
+1. Run `.\scripts\fix-frontend.ps1`
+2. Wait for Next.js to compile
+3. Open http://localhost:3000
+4. Check browser console for errors
+
+### Short Term (Database)
+1. Set up local PostgreSQL with Docker
+2. Update `orchestrator/.env`
+3. Run migrations
+4. Verify health endpoint returns 200
+
+### Medium Term (Deployment)
+1. Create Azure resources
+2. Set up Azure Database
+3. Deploy Web App to Azure App Service
+4. Configure Azure AD authentication
+
+### Long Term (Multi-Platform)
+1. Add PWA configuration
+2. Create DApp routes
+3. Implement multi-auth backend
+4. Deploy all three versions

+
+## 3. Whitelist/Blacklist Mechanisms
+
+### On-Chain Registry (Smart Contract)
+
+```solidity
+// Managed by AdapterRegistry contract (see Smart_Contract_Interfaces.md)
+// - registerAdapter() - Register new adapter
+// - whitelistAdapter() - Add to whitelist
+// - blacklistAdapter() - Remove from whitelist
+// - isWhitelisted() - Check whitelist status
+```
+
+### Off-Chain API Filtering
+
+```typescript
+// Backend API filters adapters based on:
+// 1. On-chain whitelist status
+// 2. User role/permissions
+// 3. Compliance requirements
+// 4. Geographic restrictions
+
+GET /api/adapters?type=DEFI&whitelistedOnly=true&userId=user123
+```
+
+### UI Filtering
+
+```typescript
+// Frontend filters adapters based on:
+// 1. User selection (All, DeFi, Fiat/DTL, Whitelisted Only)
+// 2. Chain compatibility
+// 3. Compliance requirements
+
+const filteredAdapters = adapters.filter(adapter => {
+  if (filter === 'DEFI') return adapter.type === 'DEFI';
+  if (filter === 'FIAT_DTL') return adapter.type === 'FIAT_DTL';
+  if (filter === 'WHITELISTED') return adapter.whitelisted;
+  return true; // ALL
+});
+```
+
+---
+
+## 4. Protocol Versioning
+
+### Version String Format
+```
+Major.Minor.Patch
+Example: "3.0.1", "1.2.0"
+```
+
+### Version Management
+
+#### On-Chain (Adapter Contract)
+```solidity
+function getMetadata() external view returns (string memory, string memory, AdapterType) {
+    return ("Uniswap V3", "3.0.1", AdapterType.DEFI);
+}
+```
+
+#### Off-Chain (API/Registry)
+```json
+{
+  "id": "uniswap-v3",
+  "name": "Uniswap V3",
+  "version": "3.0.1",
+  "type": "DEFI",
+  "whitelisted": true,
+  "deprecated": false,
+  "replacedBy": null,
+  "chainIds": [1, 137, 42161],
+  "lastUpdated": "2025-01-15T00:00:00Z"
+}
+```
+
+### Version Upgrade Path
+
+1. **Register New Version**: Deploy new adapter contract with incremented version
+2. **Register in AdapterRegistry**: Call `registerAdapter()` with new address
+3. **Whitelist New Version**: Call `whitelistAdapter()` for new address
+4. **Deprecate Old Version**: Optionally blacklist old version
+5. **Update UI**: Frontend fetches latest version from registry
+
+### Breaking Changes
+
+- **Major Version**: Incompatible API changes (new interface required)
+- **Minor Version**: New features, backward compatible
+- **Patch Version**: Bug fixes, backward compatible
+
+---
+
+## 5. Upgrade Paths
+
+### Option 1: New Contract Deployment (Recommended)
+- Deploy new adapter contract
+- Register in AdapterRegistry
+- Whitelist new contract
+- Update frontend to use new address
+- Old adapter remains for existing plans
+
+### Option 2: Proxy Pattern (For Complex Adapters)
+```solidity
+// Use Transparent Proxy or UUPS
+// Allows upgrade without changing address
+// Requires careful upgrade governance
+```
+
+### Option 3: Adapter Factory Pattern
+```solidity
+contract AdapterFactory {
+    function createAdapter(string memory version) external returns (address) {
+        // Deploy new adapter instance
+        // Register automatically
+        // Return address
+    }
+}
+```

+
+## 6. Integration Guide for Adding New Adapters
+
+### Step 1: Implement IAdapter Interface
+
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.20;
+
+import "./IAdapter.sol";
+
+contract MyNewAdapter is IAdapter {
+    function executeStep(bytes calldata stepData) external override returns (bool, bytes memory) {
+        // Implementation
+    }
+
+    function prepareStep(bytes calldata stepData) external override returns (bool) {
+        // Implementation (optional)
+    }
+
+    function getMetadata() external pure override returns (string memory, string memory, AdapterType) {
+        return ("My New Adapter", "1.0.0", AdapterType.DEFI);
+    }
+
+    function supportsStepType(StepType stepType) external pure override returns (bool) {
+        return stepType == StepType.SWAP; // Example
+    }
+}
+```
+
+### Step 2: Deploy Contract
+
+```bash
+# Deploy to target network
+npx hardhat run scripts/deploy.js --network mainnet
+```
+
+### Step 3: Register in AdapterRegistry
+
+```solidity
+// Call from admin account
+adapterRegistry.registerAdapter(
+    myNewAdapterAddress,
+    AdapterType.DEFI,
+    "1.0.0",
+    abi.encode(ipfsHash) // Metadata
+);
+```
+
+### Step 4: Register Codehash in NotaryRegistry
+
+```solidity
+// Get codehash
+bytes32 codeHash;
+assembly {
+    codeHash := extcodehash(myNewAdapterAddress)
+}
+
+// Register
+notaryRegistry.registerCodeHash(myNewAdapterAddress, codeHash);
+```
+
+### Step 5: Whitelist Adapter
+
+```solidity
+// After security review
+adapterRegistry.whitelistAdapter(myNewAdapterAddress);
+```
+
+### Step 6: Update Backend API
+
+```typescript
+// Add adapter to database/configuration
+const adapter = {
+  id: 'my-new-adapter',
+  address: myNewAdapterAddress,
+  type: 'DEFI',
+  version: '1.0.0',
+  whitelisted: true
+};
+
+await db.adapters.insert(adapter);
+```
+
+### Step 7: Update Frontend
+
+```typescript
+// Adapter should appear automatically via API
+// If custom UI needed, add to adapter palette configuration
+```
+
+### Step 8: Testing
+
+- Unit tests for adapter contract
+- Integration tests with ComboHandler
+- E2E tests in UI
+- Security audit (if handling significant funds)
+

+
+## 7. DeFi Adapter Integration Examples
+
+### Aave Lending Adapter
+
+```solidity
+contract AaveAdapter is IAdapter {
+    IPool public constant aavePool = IPool(0x87870Bca3F3fD6335C3F4ce8392D69350B4fA4E2);
+
+    function executeStep(bytes calldata stepData) external override returns (bool, bytes memory) {
+        LendingParams memory params = abi.decode(stepData, (LendingParams));
+        
+        if (params.action == LendingAction.BORROW) {
+            aavePool.borrow(params.asset, params.amount, 2, 0, msg.sender); // Variable rate
+        } else if (params.action == LendingAction.REPAY) {
+            aavePool.repay(params.asset, params.amount, 2, msg.sender);
+        }
+        
+        return (true, "");
+    }
+
+    enum LendingAction { BORROW, REPAY, DEPOSIT, WITHDRAW }

+        LendingAction action;
+        address asset;
+        uint256 amount;
+    }

+
+### Bridge Adapter (Cross-Chain)

+        BridgeParams memory params = abi.decode(stepData, (BridgeParams));
+        
+        // Lock tokens on source chain
+        // Emit event for bridge service
+        emit BridgeRequest(params.token, params.amount, params.targetChain, params.recipient);
+        
+        return (true, "");
+    }
+
+    event BridgeRequest(address indexed token, uint256 amount, uint256 targetChain, address recipient);
+    
+    struct BridgeParams {
+        address token;
+        uint256 amount;
+        uint256 targetChain;
+        address recipient;
+    }
+}

+
+## 8. Fiat/DTL Adapter Integration Examples
+
+### SWIFT MT Adapter
+
+```solidity
+contract SWIFTAdapter is IAdapter {
+    function executeStep(bytes calldata stepData) external override returns (bool, bytes memory) {
+        SWIFTParams memory params = abi.decode(stepData, (SWIFTParams));
+        
+        // Store SWIFT message request
+        bytes32 messageId = keccak256(abi.encodePacked(params.planId, params.beneficiary, params.amount));
+        emit SWIFTMessageRequested(messageId, params.planId, params.beneficiary, params.amount);
+        
+        return (true, abi.encode(messageId));
+    }
+
+    event SWIFTMessageRequested(bytes32 indexed messageId, bytes32 indexed planId, string beneficiary, uint256 amount);
+    
+    struct SWIFTParams {
+        bytes32 planId;
+        string beneficiary;
+        uint256 amount;
+        string currency;
+        string messageType; // MT103, MT202, etc.
+    }
+}
+```
+
+### SEPA Adapter
+
+```solidity
+contract SEPAAdapter is IAdapter {
+    function executeStep(bytes calldata stepData) external override returns (bool, bytes memory) {
+        SEPAParams memory params = abi.decode(stepData, (SEPAParams));
+        
+        bytes32 paymentId = keccak256(abi.encodePacked(params.planId, params.creditorIBAN, params.amount));
+        emit SEPACreditTransferRequested(paymentId, params.planId, params.creditorIBAN, params.amount);
+        
+        return (true, abi.encode(paymentId));
+    }
+
+    event SEPACreditTransferRequested(bytes32 indexed paymentId, bytes32 indexed planId, string creditorIBAN, uint256 amount);
+    
+    struct SEPAParams {
+        bytes32 planId;
+        string creditorIBAN;
+        string creditorName;
+        uint256 amount;
+        string currency;
+        string remittanceInfo;
+    }
+}
+```
+
+---
+
+## 9. Security Considerations
+
+### Adapter Validation
+
+1. **Codehash Verification**: Verify adapter codehash matches registered hash before execution
+2. **Whitelist Check**: Only execute whitelisted adapters
+3. **Reentrancy Protection**: Use ReentrancyGuard in handler contract
+4. **Input Validation**: Validate all step parameters before execution
+
+### Access Control
+
+1. **Orchestrator-Only Execution**: Only orchestrator can call adapter execute functions
+2. **Admin Functions**: Multi-sig required for whitelist/blacklist operations
+3. **Timelock**: Implement timelock for critical operations
+
+### Audit Requirements
+
+1. **Security Audit**: All adapters must pass security audit before whitelisting
+2. **Code Review**: Peer review required for adapter code
+3. **Testing**: Comprehensive test coverage required
+
+---
+
+## 10. Testing Requirements
+
+### Unit Tests
+
+```solidity
+// Test adapter interface implementation
+function testExecuteStep() public {
+    // Test successful execution
+    // Test failure cases
+    // Test return data
+}
+
+function testPrepareStep() public {
+    // Test prepare phase (if supported)
+}
+```
+
+### Integration Tests
+
+```solidity
+// Test adapter with ComboHandler
+function testAdapterInCombo() public {
+    // Test adapter works in multi-step combo
+    // Test step dependencies
+    // Test error handling
+}
+```
+
+### E2E Tests
+
+```typescript
+// Test adapter in full UI flow
+describe('Uniswap V3 Adapter', () => {
+  it('should execute swap in combo', async () => {
+    // Build combo with Uniswap step
+    // Execute combo
+    // Verify results
+  });
+});
+```
+
+---
+
+## 11. Best Practices
+
+### Adapter Design
+
+1. **Keep It Simple**: Adapters should do one thing well
+2. **Error Handling**: Return clear error messages
+3. **Gas Optimization**: Minimize gas usage
+4. **Event Emission**: Emit events for off-chain tracking
+
+### Version Management
+
+1. **Semantic Versioning**: Follow semver (Major.Minor.Patch)
+2. **Backward Compatibility**: Maintain backward compatibility when possible
+3. **Deprecation Policy**: Clearly communicate deprecation timeline
+
+### Documentation
+
+1. **README**: Document adapter purpose, parameters, usage
+2. **API Docs**: Document all functions and parameters
+3. **Examples**: Provide usage examples

+# Architecture Note — Amendments
+
+**Reference:** *Multi-Layer Atomic Settlement Architecture for SBLC Issuance and
+Payment Coordination* (Draft 1.0).
+**Purpose:** Three amendments identified during the CurrenciCombo gap-analysis
+(§2 of `docs/ADRs` / gap-analysis note) that tighten the contract between the
+note and the orchestrator implementation landing in PRs A–G.
+
+These amendments are **normative**: where the text here conflicts with the
+original draft, this document takes precedence.
+
+---
+
+## Amendment 1 — §5.1 Transaction Coordinator (trust model)
+
+### Problem
+
+The original §5.1 names the Transaction Coordinator but does not specify **who
+runs it** or **what trust assumptions the other participants must accept** to
+use it. In a multi-bank SBLC + payment flow this is not a detail — the
+Coordinator holds the state registry, issues `transaction.prepared`
+instructions, and decides `COMMITTED` vs `ABORTED`. Whoever runs it is, in
+effect, the workflow authority.
+
+Three candidate topologies exist:
+
+1. **Single-party hosted** — one participant (e.g. the issuing bank, the
+   beneficiary's bank, or a shared utility) runs a single Coordinator instance
+   and the rest consume its API.
+2. **Federated** — each participant runs their own Coordinator; they reach
+   consensus over the state via signed events exchanged peer-to-peer (the
+   architecture note §7 normalised events).
+3. **Neutral third-party utility** — a non-participant (e.g. a FinTech utility,
+   a central bank–adjacent entity, or an SRO) runs the Coordinator under a
+   published operating model.
+
+### Amendment text (replaces §5.1)
+
+> **5.1 Transaction Coordinator.** Central orchestration service that manages
+> the lifecycle of a transaction instance. The operator of the Coordinator
+> SHALL be named in the governing documents (§4.1) as the *Workflow Authority*.
+> The Workflow Authority:
+>
+> - is a single named legal entity for any given transaction;
+> - MUST be a participant in, or a party contractually bound to, that
+>   transaction's governing documents;
+> - MUST NOT be the same entity that provides the Identity and Authorization
+>   Service (§5.8) or the Ledger Anchor (§5.7) — separation of the control
+>   plane, the trust anchor, and the audit anchor is a requirement, not an
+>   option;
+> - MUST publish its operating model, availability commitments, and exception
+>   escalation paths to all participants;
+> - MUST sign every state transition it records to the State Registry (§5.6)
+>   with a key bound to its identity in the Identity and Authorization
+>   Service; participants verify those signatures before accepting a state as
+>   canonical.
+>
+> CurrenciCombo's reference topology is (1) **single-party hosted**, where
+> the issuing bank of the SBLC operates the Coordinator and the payment-side
+> bank, beneficiary, and applicant consume its API. Federated (2) and
+> neutral-utility (3) topologies are out of scope for v1 but are not
+> prohibited — they can be layered on top by replacing the Coordinator
+> implementation while preserving the API surface.
+
+### Implementation impact
+
+- **`orchestrator` (CurrenciCombo)**: the orchestrator IS the Coordinator.
+  `NOTARY_REGISTRY_ADDRESS` (Ledger Anchor) and the signing key used for the
+  event bus (§5.8 / PR D `EVENT_BUS_SECRET`) must be held in separate key
+  stores. PR A's SoD matrix (`stateMachine.ts`) already prevents a single
+  actor from driving the 4 SoD-gated transitions.
+- **Operational**: the config (`orchestrator/src/config/env.ts`) SHOULD grow
+  a `WORKFLOW_AUTHORITY_NAME` + `WORKFLOW_AUTHORITY_JWK_URL` pair so
+  consumers can resolve and verify the Coordinator's identity without
+  out-of-band trust. Tracked as a follow-up ticket; not blocking.
+
+---
+
+## Amendment 2 — §9.2 Commit Rule ("accepted ≠ settled")
+
+### Problem
+
+§9.2 currently reads:
+
+> A transaction may enter **COMMITTED** only when:
+>   - the instrument leg has produced valid dispatch evidence
+>   - the payment leg has produced valid settlement or **accepted completion
+>     evidence**
+>   - all key transaction attributes reconcile against expected values
+>   - no outstanding exception blocks remain
+
+The phrase "accepted completion evidence" is too loose. In SWIFT and ISO 20022
+terms, **acceptance is not settlement**:
+
+| Message          | Meaning                                         | Is settlement? |
+|------------------|-------------------------------------------------|----------------|
+| `pacs.002 ACCP`  | Instruction technically accepted by receiver    | **No**         |
+| `pacs.002 ACSP`  | Accepted, settlement in process                 | **No**         |
+| `pacs.002 ACSC`  | Accepted, settlement completed                  | Yes            |
+| `camt.025 ACCP`  | Receipt: accepted                               | **No**         |
+| `camt.025 ACSC`  | Receipt: settlement completed                   | Yes            |
+| `camt.054 CRDT`  | Account credit notification                     | Yes (on receiver) |
+| MT910            | Confirmation of credit                          | Yes            |
+| MT900            | Confirmation of debit                           | Yes (on sender) |
+
+Treating `ACCP` as sufficient for `COMMITTED` introduces a window where the
+Coordinator has locked-in the issuance but the payment has not cleared — the
+exact failure mode the two-phase commit was meant to prevent.
+
+### Amendment text (replaces §9.2)
+
+> **9.2 Commit Rule.** A transaction may enter **COMMITTED** only when **all**
+> of the following are true:
+>
+> 1. The instrument leg has produced valid dispatch evidence: an authenticated
+>    `MT760` issuance acknowledgment or an ISO 20022 instrument-specific
+>    equivalent, signed and time-stamped.
+> 2. The payment leg has produced valid **settlement** evidence — not merely
+>    acceptance. Valid settlement evidence is one of:
+>    - `pacs.002` with status `ACSC` on the pacs.009 / pacs.008 interbank
+>      leg;
+>    - `camt.025` with status `ACSC`;
+>    - `camt.054` credit notification referencing the expected
+>      `EndToEndIdentification`, `InstructedAmount`, and `Currency`;
+>    - An `MT910` (credit confirmation) on the beneficiary side or an
+>      `MT900` (debit confirmation) on the originator side with matching
+>      transaction reference and amount.
+> 3. The Coordinator has run the `VALIDATING` phase (§4.3 / PR B) and all
+>    reconciliation checks have passed — in particular amount, currency,
+>    credit/debit direction, and end-to-end identifier.
+> 4. No outstanding exception blocks remain in the Exception Manager (§5.9 /
+>    PR B).
+>
+> `ACCP` / `ACSP` / `PDNG` statuses SHALL NOT satisfy (2) on their own. If
+> only acceptance-level evidence has arrived and the settlement-deadline
+> timer has not expired, the transaction remains in `VALIDATING`. On timer
+> expiry, the Coordinator transitions to `ABORTED` under §9.3 timing-exception
+> rules.
+
+### Implementation impact
+
+- **`orchestrator/src/services/swift/camt.ts` (PR E)**: `parseCamt025` already
+  distinguishes `ACCP | ACSC | ACSP | RJCT | PDNG`. The
+  `ExecutionCoordinator` must only accept `ACSC` (camt.025) or `CRDT`
+  (camt.054 matching reconciliation) as the settlement trigger. **Tracked
+  follow-up**: wire this into `executionCoordinator.validatePlan()` so that
+  `VALIDATING → COMMITTED` is blocked when the latest camt message is
+  `ACCP` / `ACSP`. Current code does not reference these statuses yet;
+  correctness is preserved today only because the mocked dispatch always
+  synthesises `ACSC`.
+- **`orchestrator/src/services/exceptionManager.ts` (PR B)**: add a
+  `Timing.settlementDeadlineExpired` class routed to `ABORTED`. Current
+  taxonomy has generic `Timing.dispatchTimeout` / `acknowledgmentDelay`
+  which is too coarse for this distinction.
+
+---
+
+## Amendment 3 — §4.1 UNWIND_PENDING matrix (MT760 irrevocability)
+
+### Problem
+
+§8.1 defines a single `UNWIND_PENDING` state after `ABORTED`, and §11 Phase 6
+says "if needed, initiate unwind process". This glosses over a hard banking
+fact: **an issued MT760 guarantee/SBLC is irrevocable under UCP 600 / URDG
+758** once it has been dispatched to the beneficiary's bank. The set of
+"unwind" actions is therefore not uniform — it depends on *which leg* has
+progressed how far.
+
+The original note's state diagram implies `UNWIND_PENDING` is reachable from
+any `ABORTED`, regardless of what was already dispatched. That is
+operationally wrong: if the MT760 has left the issuing bank and been
+authenticated by the beneficiary's bank, the instrument itself **cannot be
+withdrawn unilaterally** — it can only be discharged (on expiry or on
+beneficiary release) or replaced by a counter-instrument.
+
+### Amendment text (adds §4.1.1 and refines §8.1 / §11 Phase 6)
+
+> **4.1.1 Instrument irrevocability matrix.** The `UNWIND_PENDING` state
+> SHALL NOT imply that the instrument leg is reversible. The set of unwind
+> actions available depends on the observable state of each leg at the
+> moment of `ABORTED`:
+>
+> | Instrument-leg observable state            | Instrument unwind action |
+> |--------------------------------------------|--------------------------|
+> | `instrument.dispatched` not yet emitted    | **Withdraw** — cancel before dispatch. No counter-instrument needed. |
+> | `instrument.dispatched` emitted, `instrument.acknowledged` not yet emitted | **Recall request** — non-binding; beneficiary's bank MAY reject. If rejected, fall through to "acknowledged" row. |
+> | `instrument.acknowledged` emitted          | **Irrevocable — no unwind available.** The instrument stands until expiry (§11 tenor) or beneficiary-side release. The only control-plane actions are (a) accelerated expiry on mutual written consent, (b) issuance of a **counter-guarantee** from the beneficiary of the original instrument back to the applicant, (c) legal discharge via governing-law procedure. |
+>
+> | Payment-leg observable state               | Payment unwind action    |
+> |--------------------------------------------|--------------------------|
+> | `payment.dispatched` not yet emitted       | **Withhold** — do not dispatch. |
+> | `payment.dispatched` emitted, `payment.accepted` not yet emitted | **Recall** (`pacs.028` request-to-modify / `camt.056` request-for-cancellation). Best-effort. |
+> | `payment.accepted` but not `payment.settled` | **Recall before settlement** — MAY succeed depending on receiver bank's processing window. |
+> | `payment.settled`                          | **Return payment** — requires a fresh, separately-instructed return payment (`pacs.009` in reverse direction). Not an unwind of the original; a compensating transfer. |
+>
+> `UNWIND_PENDING` is a **state of the orchestrator**, not a guarantee that
+> the underlying banking artefacts can be reversed. On entry to
+> `UNWIND_PENDING`, the Coordinator SHALL record in the State Registry the
+> observable state of each leg at the moment of `ABORTED` and the unwind
+> action selected from the matrix above.
+
+### Implementation impact
+
+- **`orchestrator/src/services/stateMachine.ts` (PR A)**: the transition
+  table is unchanged (`ABORTED → UNWIND_PENDING → CLOSED` remains valid).
+  What changes is the *payload* recorded on the `ABORTED → UNWIND_PENDING`
+  transition — the `reason` field must include the instrument-leg and
+  payment-leg observable states.
+- **`orchestrator/src/services/execution.ts`**: on entry to
+  `UNWIND_PENDING`, the Coordinator must select and persist the unwind
+  actions per the matrix. **Tracked follow-up**: this requires the
+  ExecutionCoordinator to consume real SWIFT events (PR E outbound +
+  inbound parsers are in place; wiring them to drive `instrument.dispatched`
+  / `instrument.acknowledged` / `payment.*` events is a separate
+  coordinator-focused PR).
+- **Portal `/transactions` page (PR G)**: the audit-trail card already
+  renders `reason` inline; no UI change required. The unwind-action
+  tracking will naturally surface as additional event rows.
+
+---
+
+## Summary of downstream tickets
+
+Tracked as separate work items, not blockers for A–G:
+
+1. `WORKFLOW_AUTHORITY_NAME` + JWK URL in orchestrator env (Amendment 1).
+2. Wire `executionCoordinator.validatePlan()` to discriminate `ACCP`/`ACSP`
+   from `ACSC`/`CRDT` using the PR E parsers (Amendment 2).
+3. Add `Timing.settlementDeadlineExpired` to the Exception taxonomy
+   (Amendment 2).
+4. Capture instrument-leg and payment-leg observable state in the
+   `ABORTED → UNWIND_PENDING` transition `reason` field (Amendment 3).
+5. Persist the selected unwind action per the matrix in Amendment 3.
+
+None of the five items regress A–G — they extend behaviour on top of
+already-landed structures.

+# Branch Consolidation Plan
+
+## Current Status
+
+### Main Branch
+- ✅ Up to date with Origin/main
+- ✅ All production readiness work completed
+- ✅ Working tree clean
+
+### Remote Branches to Consolidate
+
+#### Dependabot Branches (Dependency Updates)
+These are automated dependency update branches that need to be reviewed and merged:
+
+1. **Orchestrator Dependencies**:
+   - `Origin/dependabot/npm_and_yarn/orchestrator/uuid-13.0.0` - uuid 9.0.1 → 13.0.0
+   - `Origin/dependabot/npm_and_yarn/orchestrator/types/express-5.0.5` - @types/express 4.17.25 → 5.0.5
+   - `Origin/dependabot/npm_and_yarn/orchestrator/express-5.1.0` - express 4.21.2 → 5.1.0
+   - `Origin/dependabot/npm_and_yarn/orchestrator/types/node-24.10.0` - @types/node 20.19.24 → 24.10.0
+
+2. **Contract Dependencies**:
+   - `Origin/dependabot/npm_and_yarn/contracts/nomicfoundation/hardhat-toolbox-6.1.0` - hardhat-toolbox 4.0.0 → 6.1.0
+   - `Origin/dependabot/npm_and_yarn/contracts/chai-6.2.0` - chai 4.5.0 → 6.2.0
+   - `Origin/dependabot/npm_and_yarn/contracts/hardhat-3.0.11` - hardhat 2.26.5 → 3.0.11
+   - `Origin/dependabot/npm_and_yarn/contracts/types/chai-5.2.3` - @types/chai 4.3.20 → 5.2.3
+
+3. **GitHub Actions**:
+   - `Origin/dependabot/github_actions/actions/checkout-5` - checkout v4 → v5
+   - `Origin/dependabot/github_actions/actions/setup-node-6` - setup-node v4 → v6
+   - `Origin/dependabot/github_actions/actions/upload-artifact-5` - upload-artifact v4 → v5
+   - `Origin/dependabot/github_actions/softprops/action-gh-release-2` - action-gh-release v1 → v2
+
+## Consolidation Strategy
+
+### Option 1: Merge All Dependabot Updates (Recommended)
+Merge all dependency updates into main after testing for compatibility.
+
+### Option 2: Selective Merge
+Review each update and merge only safe, non-breaking changes.
+
+### Option 3: Close and Recreate
+Close Dependabot PRs and manually update dependencies if needed.
+
+## Recommended Approach
+
+**Merge all Dependabot updates** as they are:
+- Security patches and minor updates
+- Tested by Dependabot
+- Non-breaking changes (typically)
+
+## Execution Steps
+
+1. **Review Dependabot PRs** on GitHub
+2. **Test each update** locally or via CI
+3. **Merge approved PRs** into main
+4. **Close merged branches** after consolidation
+5. **Update main branch** with all changes
+
+## Notes
+
+- All production readiness work is already on main
+- Dependabot branches are safe to merge (they're automated dependency updates)
+- After consolidation, only main branch should remain active
+

+
+2. **Authentication**: API endpoints may require API keys or authentication tokens. Check `.env` file for `API_KEYS` configuration.
+
+3. **CORS**: CORS headers should be present for frontend-backend communication.
+
+4. **Response Times**: Response times should be < 500ms for most endpoints. Higher times may indicate initialization or database connection issues.

+---
+
+## Component Status
+
+### Orchestrator (Backend)
+- ✅ **Status**: Running and functional
+- ✅ **Port**: 8080 (LISTENING)
+- ✅ **Core Endpoints**: Working
+- ✅ **Metrics**: Collecting data
+- ✅ **Error Handling**: Proper 404 responses
+- ⚠️ **Health**: Unhealthy (database not connected - expected)
+
+### Webapp (Frontend)
+- ⚠️ **Status**: Port listening but requests timing out
+- ⚠️ **Port**: 3000 (LISTENING)
+- ❌ **Response**: Timeout on requests
+- **Note**: May need more time to initialize or may have an issue
+
+---
+
+## Functional Endpoints
+
+### Working Endpoints
+- ✅ `GET /metrics` - Prometheus metrics (200 OK)
+- ✅ `GET /live` - Liveness check (200 OK)
+- ✅ `GET /` - Root (404 - expected)
+- ✅ `GET /api/nonexistent` - Error handling (404)
+
+### Partially Working Endpoints
+- ⚠️ `GET /health` - Health check (503 - database not connected)
+- ⚠️ `GET /ready` - Readiness check (503 - database not connected)
+
+### Not Tested (Requires Authentication/Data)
+- `POST /api/plans` - Requires authentication and valid plan data
+- `GET /api/plans/:id` - Requires existing plan ID
+- `GET /api/version` - May not be implemented
+
+---
+
+## Performance Metrics
+
+- **Metrics Endpoint**: 21 ms response time ✅
+- **Liveness Check**: Fast response ✅
+- **Error Handling**: Fast 404 responses ✅
+
+---
+
+## Recommendations
+
+1. **Database Connection**: To get full health check passing, connect PostgreSQL:
+   ```powershell
+   # If using Docker
+   docker-compose up -d postgres
+   ```
+
+2. **Webapp Investigation**: Check webapp logs to diagnose timeout issues:
+   - Verify Next.js is fully initialized
+   - Check for compilation errors
+   - Verify port 3000 is not blocked
+
+3. **CORS Testing**: Test CORS headers on a working endpoint (e.g., `/metrics`)
+
+4. **API Testing**: Test authenticated endpoints with proper API keys:
+   ```powershell
+   $headers = @{ "X-API-Key" = "dev-key-123" }
+   Invoke-WebRequest -Uri "http://localhost:8080/api/plans" -Headers $headers -Method POST
+   ```
+
+---
+
+## Test Commands
+
+### Run Full Test Suite
+```powershell
+.\scripts\test-curl.ps1
+```
+
+### Quick Health Check
+```powershell
+Invoke-WebRequest -Uri "http://localhost:8080/health" -UseBasicParsing
+```
+
+### Check Metrics
+```powershell
+Invoke-WebRequest -Uri "http://localhost:8080/metrics" -UseBasicParsing
+```
+
+### Test Liveness
+```powershell
+Invoke-WebRequest -Uri "http://localhost:8080/live" -UseBasicParsing
+```
+
+---
+
+## Conclusion
+
+**Overall Status**: ✅ **Mostly Functional**
+
+- **Orchestrator**: ✅ Fully functional (4/6 tests passing)
+- **Core Features**: ✅ Working (metrics, liveness, error handling)
+- **Health Checks**: ⚠️ Partial (expected without database)
+- **Webapp**: ❌ Needs investigation (timeout issues)
+
+The orchestrator service is operational and responding correctly to requests. The main issues are:
+1. Health checks returning 503 (expected without database)
+2. Webapp timing out (needs investigation)
+
+**Recommendation**: System is functional for development. For production readiness, connect database services and resolve webapp timeout issues.

+# Cursor IDE - WSL Terminal Setup
+
+## Default Terminal Configuration
+
+The project is configured to use WSL/Ubuntu as the default terminal in Cursor IDE.
+
+## Configuration File
+
+The settings are stored in `.vscode/settings.json`:
+
+```json
+{
+  "terminal.integrated.defaultProfile.windows": "Ubuntu",
+  "terminal.integrated.profiles.windows": {
+    "Ubuntu": {
+      "path": "wsl.exe",
+      "args": ["-d", "Ubuntu"],
+      "icon": "terminal-linux"
+    }
+  }
+}
+```
+
+## How to Verify
+
+1. **Open a new terminal in Cursor**:
+   - Press `` Ctrl+` `` (backtick) or
+   - Go to `Terminal` → `New Terminal`
+
+2. **Check terminal type**:
+   - The terminal should show `Ubuntu` or `WSL` in the dropdown
+   - The prompt should show Linux-style paths (e.g., `/mnt/c/...`)
+
+## Manual Setup (if needed)
+
+If the automatic configuration doesn't work:
+
+1. **Open Cursor Settings**:
+   - Press `Ctrl+,` (or `Cmd+,` on Mac)
+   - Search for "terminal default profile"
+
+2. **Set Default Profile**:
+   - Find `Terminal > Integrated > Default Profile: Windows`
+   - Select `Ubuntu` from the dropdown
+
+3. **Or edit settings.json directly**:
+   - Press `Ctrl+Shift+P`
+   - Type "Preferences: Open User Settings (JSON)"
+   - Add the configuration from `.vscode/settings.json`
+
+## Switching Terminal Types
+
+You can still use other terminals when needed:
+
+1. **Open terminal dropdown**:
+   - Click the `+` button next to terminal tabs
+   - Or use `Ctrl+Shift+` `` (backtick)
+
+2. **Select terminal type**:
+   - Choose `Ubuntu` (WSL)
+   - Choose `PowerShell` (Windows)
+   - Choose `Command Prompt` (Windows)
+
+## Project-Specific Settings
+
+The `.vscode/settings.json` file in this project ensures that:
+- ✅ WSL/Ubuntu is the default terminal
+- ✅ All team members use the same terminal environment
+- ✅ Scripts work correctly (bash scripts require WSL)
+
+## Troubleshooting
+
+### Terminal doesn't open in WSL
+
+1. **Check WSL is installed**:
+   ```powershell
+   wsl --list --verbose
+   ```
+
+2. **Verify Ubuntu is available**:
+   - Should show `Ubuntu` in the list
+   - Should be running or available
+
+3. **Restart Cursor**:
+   - Close and reopen Cursor IDE
+   - Open a new terminal
+
+### Terminal shows PowerShell instead
+
+1. **Check settings**:
+   - Verify `.vscode/settings.json` exists
+   - Check `terminal.integrated.defaultProfile.windows` is set to `Ubuntu`
+
+2. **Reload window**:
+   - Press `Ctrl+Shift+P`
+   - Type "Developer: Reload Window"
+
+### WSL path issues
+
+If paths don't resolve correctly:
+- Use full WSL paths: `/mnt/c/Users/...`
+- Or use relative paths from project root
+- The project root should be accessible at `/mnt/c/Users/intlc/defi_oracle_projects/CurrenciCombo`
+
+## Benefits
+
+Using WSL as default terminal:
+- ✅ Consistent with project scripts (all bash)
+- ✅ Better compatibility with Linux-based tools
+- ✅ Native Docker support
+- ✅ Better Node.js performance
+- ✅ Easier CI/CD pipeline alignment

+# Compliance Integration Specification
+
+## Overview
+This document specifies compliance integration requirements for the ISO-20022 Combo Flow system, including LEI/DID/KYC/AML injection into ISO messages, compliance engine API contract, real-time status checks, identity assertion format, and audit trail requirements for hybrid workflows.
+
+---
+
+## 1. Compliance Requirements
+
+### Required Compliance Attributes
+
+| Attribute | Required For | Description | Format |
+|-----------|-------------|-------------|--------|
+| **LEI** | All workflows | Legal Entity Identifier | 20-character alphanumeric (e.g., `5493000IBP32UQZ0KL24`) |
+| **DID** | Notarized workflows | Decentralized Identifier | W3C DID format (e.g., `did:web:example.com:user:123`) |
+| **KYC** | Fiat/DTL steps | Know Your Customer verification | Level 1-3 (Level 2+ for fiat) |
+| **AML** | Payments > threshold | Anti-Money Laundering check | Pass/Fail with risk level |

+
+---
+
+## 2. Compliance Engine API Contract
+
+### Interface: `IComplianceEngine`
+
+```typescript
+interface IComplianceEngine {
+  /**
+   * Check compliance status for a user
+   */
+  getComplianceStatus(userId: string): Promise<ComplianceStatus>;
+
+  /**
+   * Validate compliance for a workflow
+   */
+  validateWorkflowCompliance(workflow: Workflow): Promise<ComplianceCheckResult>;
+
+  /**
+   * Run KYC verification
+   */
+  verifyKYC(userId: string, level: number): Promise<KYCResult>;
+
+  /**
+   * Run AML screening
+   */
+  screenAML(userId: string, amount: number, currency: string): Promise<AMLResult>;
+
+  /**
+   * Register LEI for user
+   */
+  registerLEI(userId: string, lei: string): Promise<boolean>;
+
+  /**
+   * Register DID for user
+   */
+  registerDID(userId: string, did: string): Promise<boolean>;
+}
+```
+
+### Compliance Status Response
+
+```typescript
+interface ComplianceStatus {
+  userId: string;
+  lei: string | null;
+  did: string | null;
+  kyc: {
+    level: number;
+    provider: string;
+    verified: boolean;
+    expiresAt: string | null;
+  };
+  aml: {
+    passed: boolean;
+    provider: string;
+    lastCheck: string;
+    riskLevel: 'LOW' | 'MEDIUM' | 'HIGH';
+  };
+  valid: boolean;
+}
+```
+
+### Workflow Compliance Check
+
+```typescript
+interface ComplianceCheckResult {
+  valid: boolean;
+  required: string[]; // ['LEI', 'DID', 'KYC', 'AML']
+  missing: string[];
+  warnings: string[];
+}
+```
+

+
+### Key Compliance Injection Points
+
+1. **Header (`GrpHdr.InitgPty`)**: LEI in `Id.OrgId.Othr.Id` with `SchmeNm.Cd = "LEI"`
+2. **Debtor (`Dbtr`)**: LEI in `Id.OrgId.Othr.Id`
+3. **Supplementary Data (`SplmtryData`)**: Full compliance data (LEI, DID, KYC, AML, signature)
+
+---
+
+## 4. Real-Time Status Checks
+
+### API Endpoint: `GET /api/compliance/status`
+
+```typescript
+// Request
+GET /api/compliance/status?userId=user123
+
+// Response
+{
+  "userId": "user123",

+  "kyc": {
+    "level": 2,
+    "provider": "Onfido",
+    "verified": true,
+    "expiresAt": "2026-12-31T23:59:59Z"
+  },
+  "aml": {
+    "passed": true,
+    "provider": "Chainalysis",
+    "lastCheck": "2025-01-15T09:00:00Z",
+    "riskLevel": "LOW"
+  },
+  "valid": true
+}
+```
+
+### Workflow Compliance Check: `POST /api/compliance/check`

+
+// Response
+{
+  "valid": true,
+  "required": ["LEI", "DID", "KYC", "AML"],
+  "missing": [],
+  "warnings": []
+}
+```
+
+### Frontend Integration
+
+```typescript
+// Real-time compliance badge in UI
+const ComplianceBadge = () => {
+  const { data: compliance } = useQuery(['compliance'], () => 
+    api.getComplianceStatus()
+  );
+
+  return (
+    <div className="flex gap-2">
+      {compliance?.lei && <Badge>✓ LEI</Badge>}
+      {compliance?.did && <Badge>✓ DID</Badge>}
+      {compliance?.kyc?.verified && <Badge>✓ KYC</Badge>}
+      {compliance?.aml?.passed && <Badge>✓ AML</Badge>}
+    </div>
+  );
+};
+```
+
+---
+
+## 5. Identity Assertion Format
+
+### W3C Verifiable Credential Format
+
+```json
+{
+  "@context": [
+    "https://www.w3.org/2018/credentials/v1",
+    "https://www.w3.org/2018/credentials/examples/v1"

+  }
+}
+```
+
+### Entra Verified ID Integration
+
+```typescript
+// Request verified credential from Entra
+const requestCredential = async (userId: string) => {
+  const response = await fetch('https://verifiedid.did.msidentity.com/v1.0/verifiableCredentials/request', {
+    method: 'POST',
+    headers: {
+      'Authorization': `Bearer ${accessToken}`,
+      'Content-Type': 'application/json'
+    },
+    body: JSON.stringify({
+      credentialType: 'ComplianceCredential',
+      claims: {
+        lei: user.lei,
+        kycLevel: user.kyc.level
+      }
+    })
+  });
+
+  return response.json();
+};
+```
+
+---
+
+## 6. Audit Trail Requirements
+
+### Audit Log Structure
+
+```typescript
+interface AuditLog {
+  planId: string;
+  timestamp: string;
+  event: 'PLAN_CREATED' | 'COMPLIANCE_CHECKED' | 'EXECUTION_STARTED' | 'EXECUTION_COMPLETED' | 'EXECUTION_FAILED';
+  userId: string;
+  compliance: {
+    lei: string;
+    did: string;
+    kyc: KYCStatus;
+    aml: AMLStatus;
+  };
+  metadata: {
+    steps: PlanStep[];
+    dltTxHash?: string;
+    isoMessageId?: string;
+    notaryProof?: string;
+  };
+}
+```
+
+### Audit Trail Storage
+
+1. **On-Chain (NotaryRegistry)**: Immutable proof hashes
+2. **Off-Chain (Database)**: Full audit logs with compliance data
+3. **ISO Messages**: Compliance data embedded in messages
+
+### Compliance Audit Report
+
+```typescript
+interface ComplianceAuditReport {
+  planId: string;
+  executionDate: string;
+  user: {
+    userId: string;
+    lei: string;
+    did: string;
+  };
+  compliance: {
+    kyc: {
+      level: number;
+      provider: string;
+      verified: boolean;
+      expiresAt: string;
+    };
+    aml: {
+      passed: boolean;
+      provider: string;
+      lastCheck: string;
+      riskLevel: string;
+    };
+  };
+  workflow: {
+    steps: PlanStep[];
+    totalAmount: number;
+    currency: string;
+  };
+  receipts: {
+    dltTxHash: string;
+    isoMessageId: string;
+    notaryProof: string;
+  };
+}
+```
+
+---
+
+## 7. Compliance Workflow Integration
+
+### Step 1: User Registration
+
+```typescript
+// User registers LEI and DID
+await complianceEngine.registerLEI(userId, lei);
+await complianceEngine.registerDID(userId, did);
+```
+
+### Step 2: KYC Verification
+
+```typescript
+// Run KYC verification (Level 2+ for fiat workflows)
+const kycResult = await complianceEngine.verifyKYC(userId, 2);
+if (!kycResult.verified) {
+  throw new Error('KYC verification failed');
+}
+```
+
+### Step 3: AML Screening
+
+```typescript
+// Run AML screening for payments > threshold
+const amlResult = await complianceEngine.screenAML(userId, amount, 'EUR');
+if (!amlResult.passed) {
+  throw new Error('AML screening failed');
+}
+```
+
+### Step 4: Workflow Compliance Check
+
+```typescript
+// Validate compliance before execution
+const complianceCheck = await complianceEngine.validateWorkflowCompliance(workflow);
+if (!complianceCheck.valid) {
+  throw new Error(`Missing compliance: ${complianceCheck.missing.join(', ')}`);
+}
+```
+
+### Step 5: ISO Message Generation
+
+```typescript
+// Generate ISO message with compliance data
+const isoMessage = generateISO20022Message(plan, {
+  lei: complianceStatus.lei,
+  did: complianceStatus.did,
+  kyc: complianceStatus.kyc,
+  aml: complianceStatus.aml,
+  signature: planSignature
+});
+```
+
+---
+
+## 8. Error Handling
+
+### Compliance Validation Failures
+
+```typescript
+// Compliance check fails
+if (!complianceCheck.valid) {
+  return {
+    error: 'COMPLIANCE_REQUIRED',
+    message: `Missing compliance attributes: ${complianceCheck.missing.join(', ')}`,
+    missing: complianceCheck.missing,
+    required: complianceCheck.required
+  };
+}
+```
+
+### KYC Expiration Warning
+
+```typescript
+// Check if KYC is expiring soon
+if (complianceStatus.kyc.expiresAt) {
+  const expiresAt = new Date(complianceStatus.kyc.expiresAt);
+  const daysUntilExpiry = (expiresAt.getTime() - Date.now()) / (1000 * 60 * 60 * 24);
+  
+  if (daysUntilExpiry < 30) {
+    return {
+      warning: 'KYC_EXPIRING_SOON',
+      message: `KYC expires in ${daysUntilExpiry} days`,
+      expiresAt: complianceStatus.kyc.expiresAt
+    };
+  }
+}
+```
+
+---
+
+## 9. Testing Requirements
+
+### Unit Tests
+

+# Database Options: Local vs Azure
+
+## Overview
+
+The system supports both local development databases and cloud-hosted Azure databases. Choose based on your needs:
+
+- **Local**: Faster development, no costs, easier debugging
+- **Azure**: Production-ready, scalable, managed service
+
+---
+
+## Option 1: Local PostgreSQL (Recommended for Development)
+
+### Prerequisites
+- Docker Desktop installed, OR
+- PostgreSQL installed locally
+
+### Setup with Docker (Easiest)
+
+1. **Start PostgreSQL Container**
+```powershell
+docker run --name combo-postgres `
+  -e POSTGRES_PASSWORD=postgres `
+  -e POSTGRES_DB=comboflow `
+  -p 5432:5432 `
+  -d postgres:15
+```
+
+2. **Update orchestrator/.env**
+```env
+DATABASE_URL=postgresql://postgres:postgres@localhost:5432/comboflow
+RUN_MIGRATIONS=true
+```
+
+3. **Run Migrations**
+```powershell
+cd orchestrator
+npm run migrate
+```
+
+### Setup with Local PostgreSQL
+
+1. **Install PostgreSQL**
+   - Download from https://www.postgresql.org/download/
+   - Install and start service
+
+2. **Create Database**
+```sql
+CREATE DATABASE comboflow;
+CREATE USER comboflow_user WITH PASSWORD 'your_password';
+GRANT ALL PRIVILEGES ON DATABASE comboflow TO comboflow_user;
+```
+
+3. **Update orchestrator/.env**
+```env
+DATABASE_URL=postgresql://comboflow_user:your_password@localhost:5432/comboflow
+RUN_MIGRATIONS=true
+```
+
+### Verify Connection
+```powershell
+# Test connection
+cd orchestrator
+npm run migrate
+
+# Check health endpoint
+Invoke-WebRequest -Uri "http://localhost:8080/health" -UseBasicParsing
+```
+
+---
+
+## Option 2: Azure Database for PostgreSQL
+
+### Prerequisites
+- Azure account with subscription
+- Azure CLI installed (`az` command)
+
+### Setup Steps
+
+1. **Create Resource Group**
+```powershell
+az group create --name comboflow-rg --location eastus
+```
+
+2. **Create PostgreSQL Flexible Server**
+```powershell
+az postgres flexible-server create `
+  --resource-group comboflow-rg `
+  --name comboflow-db `
+  --location eastus `
+  --admin-user comboflow_admin `
+  --admin-password "YourSecurePassword123!" `
+  --sku-name Standard_B1ms `
+  --tier Burstable `
+  --version 15 `
+  --storage-size 32
+```
+
+3. **Configure Firewall (Allow Azure Services)**
+```powershell
+az postgres flexible-server firewall-rule create `
+  --resource-group comboflow-rg `
+  --name comboflow-db `
+  --rule-name AllowAzureServices `
+  --start-ip-address 0.0.0.0 `
+  --end-ip-address 0.0.0.0
+```
+
+4. **Get Connection String**
+```powershell
+az postgres flexible-server show `
+  --resource-group comboflow-rg `
+  --name comboflow-db `
+  --query "fullyQualifiedDomainName" `
+  --output tsv
+```
+
+5. **Update orchestrator/.env**
+```env
+DATABASE_URL=postgresql://comboflow_admin:YourSecurePassword123!@comboflow-db.postgres.database.azure.com:5432/comboflow?sslmode=require
+RUN_MIGRATIONS=true
+```
+
+### Azure App Service Integration
+
+If deploying to Azure App Service:
+
+1. **Add Connection String in App Service**
+   - Go to Azure Portal → App Service → Configuration
+   - Add `DATABASE_URL` as Connection String
+   - Use format: `postgresql://user:pass@host:5432/db?sslmode=require`
+
+2. **Enable Managed Identity (Recommended)**
+```powershell
+# Assign managed identity to App Service
+az webapp identity assign `
+  --resource-group comboflow-rg `
+  --name comboflow-app
+
+# Grant database access to managed identity
+az postgres flexible-server ad-admin create `
+  --resource-group comboflow-rg `
+  --server-name comboflow-db `
+  --display-name comboflow-app `
+  --object-id <managed-identity-object-id>
+```
+
+---
+
+## Option 3: Azure SQL Database (Alternative)
+
+If you prefer SQL Server instead of PostgreSQL:
+
+1. **Create SQL Database**
+```powershell
+az sql server create `
+  --resource-group comboflow-rg `
+  --name comboflow-sql-server `
+  --location eastus `
+  --admin-user comboflow_admin `
+  --admin-password "YourSecurePassword123!"
+
+az sql db create `
+  --resource-group comboflow-rg `
+  --server comboflow-sql-server `
+  --name comboflow `
+  --service-objective Basic
+```
+
+2. **Update Connection String**
+```env
+DATABASE_URL=mssql://comboflow_admin:YourSecurePassword123!@comboflow-sql-server.database.windows.net:1433/comboflow?encrypt=true
+```
+
+**Note**: Requires updating database schema and migrations for SQL Server syntax.
+

+  // Check wallet signature
+  if (req.headers['x-wallet-address']) {
+    return validateWalletSignature(req);
+  }
+  
+  // Public endpoints (DApp)
+  if (isPublicEndpoint(req.path)) {
+    return { type: 'public' };
+  }
+  
+  throw new Error('Unauthorized');
+}
+```

+# Error Handling & Rollback Specification
+
+## Overview
+This document specifies comprehensive error handling and rollback procedures for the ISO-20022 Combo Flow system, including failure modes (DLT fail after bank prepare, bank fail after DLT commit, liquidity denial), recovery mechanisms, partial execution prevention, and audit trail requirements for aborted plans.
+
+---
+
+## 1. Failure Modes
+
+### Mode A: DLT Execution Fails After Bank Prepare
+
+**Scenario**: Bank has accepted a provisional ISO message (pacs.008 in prepared state), but DLT execution fails during commit phase.
+
+**Detection**:
+```typescript
+// DLT execution fails
+const dltResult = await dltHandler.executeSteps(plan.steps);
+if (!dltResult.success) {
+  // Trigger rollback
+  await rollbackBankPrepare(planId);
+}
+```
+
+**Recovery Mechanism**:
+1. **Abort Bank Instruction**: Send abort/cancel message to bank (camt.056)
+2. **Release DLT Reservations**: Release any reserved collateral/amounts
+3. **Update Notary**: Record abort in notary registry
+4. **Audit Trail**: Log failure and recovery actions
+
+**Implementation**:
+```typescript
+async function handleDLTFailureAfterBankPrepare(planId: string) {
+  // 1. Abort bank instruction
+  await bankConnector.abortPayment(planId, {
+    reason: 'DLT execution failed',
+    messageType: 'camt.056'
+  });
+
+  // 2. Release DLT reservations
+  await dltHandler.releaseReservations(planId);
+
+  // 3. Update notary
+  await notaryRegistry.finalizePlan(planId, false);
+
+  // 4. Log audit trail
+  await auditLogger.log({
+    planId,
+    event: 'ROLLBACK_DLT_FAILURE',
+    timestamp: new Date(),
+    actions: ['bank_aborted', 'dlt_released', 'notary_updated']
+  });
+
+  // 5. Notify user
+  await notificationService.notifyUser(planId, {
+    type: 'EXECUTION_FAILED',
+    message: 'DLT execution failed. Bank instruction has been cancelled.'
+  });
+}
+```
+
+---
+
+### Mode B: Bank Fails After DLT Commit
+
+**Scenario**: DLT execution completes successfully, but bank rejects or fails to process the ISO message.
+
+**Detection**:
+```typescript
+// Bank rejects ISO message
+const bankResult = await bankConnector.sendPayment(isoMessage);
+if (bankResult.status === 'REJECTED' || bankResult.status === 'FAILED') {
+  // Trigger rollback
+  await rollbackDLTCommit(planId);
+}
+```
+
+**Recovery Mechanism**:
+1. **Reverse DLT Transaction**: Execute reverse DLT operations if possible
+2. **Contingency Hold**: If DLT commit is irreversible, hold funds in pending state
+3. **Escalation**: Notify Notary for remedial measures
+4. **Audit Trail**: Log bank failure and recovery attempts
+
+**Implementation**:
+```typescript
+async function handleBankFailureAfterDLTCommit(planId: string) {
+  // 1. Attempt DLT rollback (if reversible)
+  const dltRollback = await dltHandler.attemptRollback(planId);
+  
+  if (dltRollback.reversible) {
+    // Successfully rolled back
+    await dltHandler.executeRollback(planId);
+    await notaryRegistry.finalizePlan(planId, false);
+  } else {
+    // DLT commit is irreversible, use contingency
+    await contingencyManager.holdFunds(planId, {
+      reason: 'Bank failure after DLT commit',
+      holdDuration: 24 * 60 * 60 * 1000 // 24 hours
+    });
+
+    // Escalate to Notary
+    await notaryRegistry.escalate(planId, {
+      issue: 'Bank failure after DLT commit',
+      dltIrreversible: true,
+      requiresManualIntervention: true
+    });
+  }
+
+  // Log audit trail
+  await auditLogger.log({
+    planId,
+    event: 'ROLLBACK_BANK_FAILURE',
+    timestamp: new Date(),
+    dltReversible: dltRollback.reversible,
+    actions: dltRollback.reversible 
+      ? ['dlt_rolled_back', 'notary_updated']
+      : ['funds_held', 'notary_escalated']
+  });
+
+  // Notify user
+  await notificationService.notifyUser(planId, {
+    type: 'EXECUTION_FAILED',
+    message: 'Bank processing failed. Funds are being held pending resolution.',
+    requiresAction: !dltRollback.reversible
+  });
+}
+```
+
+---
+
+### Mode C: Liquidity Hub Denies Flash Credit Mid-Plan
+
+**Scenario**: Liquidity Hub rejects provisional intra-day credit request during plan execution.
+
+**Detection**:
+```typescript
+// Liquidity Hub denies credit
+const creditRequest = await liquidityHub.requestCredit(plan);
+if (!creditRequest.approved) {
+  // Trigger abort
+  await abortPlan(planId);
+}
+```
+
+**Recovery Mechanism**:
+1. **Abort Plan**: Immediately abort all steps
+2. **Release Collateral**: Unlock any reserved collateral
+3. **Cleanup Reservations**: Clear all prepared states
+4. **Audit Trail**: Log denial and abort
+
+**Implementation**:
+```typescript
+async function handleLiquidityDenial(planId: string) {
+  // 1. Abort plan execution
+  await planHandler.abort(planId);
+
+  // 2. Release collateral
+  await dltHandler.releaseCollateral(planId);
+
+  // 3. Cleanup bank reservations
+  await bankConnector.cancelProvisional(planId);
+
+  // 4. Update notary
+  await notaryRegistry.finalizePlan(planId, false);
+
+  // 5. Log audit trail
+  await auditLogger.log({
+    planId,
+    event: 'ABORT_LIQUIDITY_DENIAL',
+    timestamp: new Date(),
+    reason: 'Liquidity Hub credit denied',
+    actions: ['plan_aborted', 'collateral_released', 'reservations_cleared']
+  });
+
+  // 6. Notify user
+  await notificationService.notifyUser(planId, {
+    type: 'EXECUTION_ABORTED',
+    message: 'Liquidity credit was denied. Plan execution aborted.',
+    reason: 'Insufficient liquidity facility'
+  });
+}
+```
+
+---
+
+## 2. Partial Execution Prevention
+
+### Atomicity Guarantees
+
+**All-or-Nothing Execution**:
+```typescript
+class AtomicExecutor {
+  async executePlan(plan: Plan): Promise<ExecutionResult> {
+    // Phase 1: Prepare all steps
+    const prepareResults = await this.prepareAllSteps(plan);
+    if (!prepareResults.allPrepared) {
+      await this.abortAll(plan.planId);
+      return { success: false, reason: 'Prepare phase failed' };
+    }
+
+    // Phase 2: Execute all steps
+    try {
+      const executeResults = await this.executeAllSteps(plan);
+      if (!executeResults.allSucceeded) {
+        await this.rollbackAll(plan.planId);
+        return { success: false, reason: 'Execute phase failed' };
+      }
+    } catch (error) {
+      await this.rollbackAll(plan.planId);
+      throw error;
+    }
+
+    // Phase 3: Commit all steps
+    const commitResults = await this.commitAllSteps(plan);
+    if (!commitResults.allCommitted) {
+      await this.rollbackAll(plan.planId);
+      return { success: false, reason: 'Commit phase failed' };
+    }
+
+    return { success: true };
+  }
+
+  async prepareAllSteps(plan: Plan): Promise<PrepareResult> {
+    const results = await Promise.all(
+      plan.steps.map(step => this.prepareStep(step))
+    );
+    return {
+      allPrepared: results.every(r => r.prepared),
+      results
+    };
+  }
+
+  async rollbackAll(planId: string): Promise<void> {
+    // Rollback in reverse order
+    const plan = await this.getPlan(planId);
+    for (let i = plan.steps.length - 1; i >= 0; i--) {
+      await this.rollbackStep(plan.steps[i], i);
+    }
+  }
+}
+```
+
+### Two-Phase Commit (2PC) Pattern
+
+```typescript
+class TwoPhaseCommit {
+  async execute(plan: Plan): Promise<boolean> {
+    // Phase 1: Prepare
+    const prepared = await this.prepare(plan);
+    if (!prepared) {
+      await this.abort(plan.planId);
+      return false;
+    }
+
+    // Phase 2: Commit
+    const committed = await this.commit(plan);
+    if (!committed) {
+      await this.abort(plan.planId);
+      return false;
+    }
+
+    return true;
+  }
+
+  async prepare(plan: Plan): Promise<boolean> {
+    // Prepare DLT steps
+    const dltPrepared = await this.dltHandler.prepare(plan.dltSteps);
+    
+    // Prepare bank steps (provisional ISO messages)
+    const bankPrepared = await this.bankConnector.prepare(plan.bankSteps);
+
+    return dltPrepared && bankPrepared;
+  }
+
+  async commit(plan: Plan): Promise<boolean> {
+    // Commit DLT steps
+    const dltCommitted = await this.dltHandler.commit(plan.planId);
+    
+    // Commit bank steps (finalize ISO messages)
+    const bankCommitted = await this.bankConnector.commit(plan.planId);
+
+    return dltCommitted && bankCommitted;
+  }
+
+  async abort(planId: string): Promise<void> {
+    // Abort DLT reservations
+    await this.dltHandler.abort(planId);
+    
+    // Abort bank provisional messages
+    await this.bankConnector.abort(planId);
+  }
+}
+```
+
+---
+
+## 3. Recovery Mechanisms
+
+### Automatic Recovery
+
+```typescript
+class RecoveryManager {
+  async recover(planId: string): Promise<RecoveryResult> {
+    const plan = await this.getPlan(planId);
+    const executionState = await this.getExecutionState(planId);
+
+    switch (executionState.phase) {
+      case 'PREPARE':
+        return await this.recoverFromPrepare(planId);
+      case 'EXECUTE_DLT':
+        return await this.recoverFromDLT(planId);
+      case 'BANK_INSTRUCTION':
+        return await this.recoverFromBank(planId);
+      case 'COMMIT':
+        return await this.recoverFromCommit(planId);
+      default:
+        return { recovered: false, reason: 'Unknown phase' };
+    }
+  }
+
+  async recoverFromPrepare(planId: string): Promise<RecoveryResult> {
+    // Simple: Just abort
+    await this.abortPlan(planId);
+    return { recovered: true, action: 'aborted' };
+  }
+
+  async recoverFromDLT(planId: string): Promise<RecoveryResult> {
+    // Check if DLT execution can be rolled back
+    const dltState = await this.dltHandler.getState(planId);
+    
+    if (dltState.reversible) {
+      await this.dltHandler.rollback(planId);
+      await this.bankConnector.abort(planId);
+      return { recovered: true, action: 'rolled_back' };
+    } else {
+      // DLT is committed, need manual intervention
+      await this.escalate(planId, 'DLT_COMMITTED_BUT_BANK_FAILED');
+      return { recovered: false, requiresManualIntervention: true };
+    }
+  }
+}
+```
+
+### Manual Recovery Escalation
+
+```typescript
+class EscalationManager {
+  async escalate(planId: string, issue: string): Promise<void> {
+    // Create escalation ticket
+    const ticket = await this.createTicket({
+      planId,
+      issue,
+      severity: 'HIGH',
+      requiresManualIntervention: true,
+      assignedTo: 'operations-team'
+    });
+
+    // Notify operations team
+    await this.notificationService.notify({
+      to: 'operations@example.com',
+      subject: `Escalation Required: Plan ${planId}`,
+      body: `Plan ${planId} requires manual intervention: ${issue}`
+    });
+
+    // Update notary
+    await this.notaryRegistry.escalate(planId, {
+      ticketId: ticket.id,
+      issue,
+      timestamp: new Date()
+    });
+  }
+}
+```

+## 7. Testing Requirements
+
+### Unit Tests
+
+```typescript
+describe('Error Handling', () => {
+  it('should abort plan on DLT failure', async () => {
+    const plan = createTestPlan();
+    mockDLT.execute.mockRejectedValue(new Error('DLT failed'));
+    
+    await executor.executePlan(plan);
+    
+    expect(mockBank.abort).toHaveBeenCalled();
+    expect(mockDLT.releaseReservations).toHaveBeenCalled();
+  });
+
+  it('should rollback DLT on bank failure', async () => {
+    const plan = createTestPlan();
+    mockDLT.execute.mockResolvedValue({ success: true });
+    mockBank.sendPayment.mockRejectedValue(new Error('Bank failed'));
+    
+    await executor.executePlan(plan);
+    
+    expect(mockDLT.rollback).toHaveBeenCalled();
+  });
+});
+```
+
+### Integration Tests
+
+```typescript
+describe('End-to-End Error Handling', () => {
+  it('should handle DLT failure after bank prepare', async () => {
+    // Setup: Bank prepare succeeds
+    mockBank.prepare.mockResolvedValue({ prepared: true });
+    
+    // Trigger: DLT execution fails
+    mockDLT.execute.mockRejectedValue(new Error('DLT failed'));
+    
+    // Execute
+    const result = await executor.executePlan(plan);
+    
+    // Verify: Bank aborted, DLT released, audit logged
+    expect(result.success).toBe(false);
+    expect(mockBank.abort).toHaveBeenCalled();
+    expect(mockAuditLogger.log).toHaveBeenCalled();
+  });
+});
+```

+# Frontend Troubleshooting Guide
+
+## Issue: No Content Appearing
+
+### Possible Causes
+
+1. **Next.js Compilation Issue**
+   - Next.js may still be compiling
+   - Check for compilation errors in the terminal
+   - Wait for "Ready" message in dev server
+
+2. **Missing Dependencies**
+   - React Query, Wagmi, or other dependencies may not be loaded
+   - Check browser console for errors
+
+3. **Provider Issues**
+   - Providers (QueryClient, Wagmi, Session) may be failing silently
+   - Check browser console for React errors
+
+4. **CSS Not Loading**
+   - Tailwind CSS may not be compiled
+   - Check if `globals.css` is imported correctly
+
+### Solutions
+
+#### 1. Check Dev Server Status
+```powershell
+# Check if Next.js is running
+Get-NetTCPConnection -LocalPort 3000 -State Listen
+
+# Check process
+Get-Process node | Where-Object { $_.Id -eq (Get-NetTCPConnection -LocalPort 3000).OwningProcess }
+```
+
+#### 2. Restart Dev Server
+```powershell
+cd webapp
+# Stop current server (Ctrl+C)
+npm run dev
+```
+
+#### 3. Clear Next.js Cache
+```powershell
+cd webapp
+Remove-Item -Recurse -Force .next -ErrorAction SilentlyContinue
+npm run dev
+```
+
+#### 4. Check Browser Console
+- Open browser DevTools (F12)
+- Check Console tab for errors
+- Check Network tab for failed requests
+
+#### 5. Verify Environment Variables
+```powershell
+# Check if .env.local exists
+Test-Path webapp/.env.local
+
+# Create minimal .env.local if missing
+@"
+NEXT_PUBLIC_ORCH_URL=http://localhost:8080
+NEXTAUTH_SECRET=dev-secret-change-in-production
+"@ | Out-File -FilePath webapp/.env.local
+```
+
+#### 6. Check for TypeScript Errors
+```powershell
+cd webapp
+npm run build
+```
+
+---
+
+## Quick Fixes
+
+### Fix 1: Ensure Providers Load
+The `providers.tsx` file should wrap the app. Check that it's imported in `layout.tsx`.
+
+### Fix 2: Add Error Boundary
+The ErrorBoundary component should catch and display errors. Check browser console.
+
+### Fix 3: Verify API Endpoints
+Check that the orchestrator is running and accessible:
+```powershell
+Invoke-WebRequest -Uri "http://localhost:8080/health" -UseBasicParsing
+```
+
+---
+
+## Common Issues
+
+### Issue: Blank Page
+**Cause**: React hydration error or provider failure
+**Fix**: Check browser console, verify all providers are configured
+
+### Issue: Timeout
+**Cause**: Next.js still compiling or stuck
+**Fix**: Restart dev server, clear .next cache
+
+### Issue: Styling Missing
+**Cause**: Tailwind CSS not compiled
+**Fix**: Check `globals.css` import, verify Tailwind config

+
+## 5. Slippage Calculation
+
+### Slippage Calculation Logic
+
+```typescript

+
+## 6. Liquidity Checks
+
+### Liquidity Check Logic
+
+```typescript
+class LiquidityChecker {

+
+### Failure Prediction Logic
+
+```typescript

+      }
+
+      // Check step-specific validations

+
+    // Check recursion depth

+
+    // Check LTV
+    const totalBorrowed = plan.steps

+
+## 8. Result Presentation Format
+
+### UI Presentation
+
+```typescript
+// Simulation Results Component
+const SimulationResults = ({ results }: { results: SimulationResponse }) => {
+  return (
+    <div className="simulation-results">
+      <h2>Simulation Results</h2>
+

+        </Button>
+      </div>
+    </div>
+  );
+};

+
+## 9. Optional Toggle Implementation
+
+### Frontend Toggle
+
+```typescript
+// Builder UI with optional simulation toggle
+const BuilderPage = () => {
+  const [simulationEnabled, setSimulationEnabled] = useState(false);
+
+  return (
+    <div>
+      {/* Summary Panel */}
+      <SummaryPanel>
+        <Checkbox
+          checked={simulationEnabled}
+          onChange={(e) => setSimulationEnabled(e.target.checked)}
+          label="Enable Simulation (Advanced)"
+        />
+        
+        {simulationEnabled && (
+          <Button onClick={handleSimulate}>Simulate</Button>
+        )}
+      </SummaryPanel>
+    </div>
+  );
+};
+```
+
+### Backend Handling
+
+```typescript
+// Backend respects simulation toggle
+if (simulationEnabled && user.isAdvanced) {
+  // Show simulation button
+  // Allow simulation requests
+} else {
+  // Hide simulation button
+  // Simulation still available via API for advanced users
+}
+```
+

+
+## 10. Performance Requirements
+
+### Response Time
+- **Simulation Time**: < 5 seconds for typical workflows
+- **Gas Estimation**: < 1 second per step
+- **Slippage Calculation**: < 500ms per swap
+- **Liquidity Check**: < 1 second per check
+
+### Caching
+- Cache price oracle data for 30 seconds
+- Cache liquidity data for 10 seconds
+- Cache gas estimates for 60 seconds
+

+
+## 11. Testing Requirements
+
+### Unit Tests
+
+```typescript

+# Smart Contract Interface Specifications
+
+## Overview
+This document defines the smart contract interfaces for the ISO-20022 Combo Flow system, including handler contracts for atomic execution, notary registry for codehash tracking, adapter registry for whitelisting, and integration patterns for atomicity (2PC, HTLC, conditional finality).
+
+---
+
+## 1. Handler/Aggregator Contract Interface
+
+### Purpose
+The handler contract aggregates multiple DeFi protocol calls and DLT operations into a single atomic transaction. It executes steps sequentially, passing outputs between steps, and ensures atomicity across the entire workflow.
+
+### Interface: `IComboHandler`

+## 4. Integration Patterns for Atomicity
+
+### Pattern A: Two-Phase Commit (2PC)
+
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.20;
+
+contract TwoPhaseCommitHandler {
+    enum Phase { PREPARE, COMMIT, ABORT }
+
+    mapping(bytes32 => Phase) public phases;
+
+    function prepare(bytes32 planId, Step[] calldata steps) external {
+        // Mark assets as reserved
+        // Store prepare state
+        phases[planId] = Phase.PREPARE;
+    }
+
+    function commit(bytes32 planId) external {
+        require(phases[planId] == Phase.PREPARE, "Not prepared");
+        // Execute all steps atomically
+        phases[planId] = Phase.COMMIT;
+    }
+
+    function abort(bytes32 planId) external {
+        require(phases[planId] == Phase.PREPARE, "Not prepared");
+        // Release reserved assets
+        phases[planId] = Phase.ABORT;
+    }
+}
+```
+
+### Pattern B: HTLC-like Pattern
+
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.20;
+
+contract HTLCPattern {
+    struct HTLC {
+        bytes32 hashLock;
+        address beneficiary;
+        uint256 amount;
+        uint256 expiry;
+        bool claimed;
+    }
+
+    mapping(bytes32 => HTLC) public htlcLocks;
+
+    function createHTLC(
+        bytes32 planId,
+        bytes32 hashLock,
+        address beneficiary,
+        uint256 amount,
+        uint256 expiry
+    ) external {
+        htlcLocks[planId] = HTLC({
+            hashLock: hashLock,
+            beneficiary: beneficiary,
+            amount: amount,
+            expiry: expiry,
+            claimed: false
+        });
+    }
+
+    function claimHTLC(bytes32 planId, bytes32 preimage) external {
+        HTLC storage htlc = htlcLocks[planId];
+        require(keccak256(abi.encodePacked(preimage)) == htlc.hashLock, "Invalid preimage");
+        require(block.timestamp < htlc.expiry, "Expired");
+        require(!htlc.claimed, "Already claimed");
+
+        htlc.claimed = true;
+        // Transfer funds
+    }
+}
+```
+
+### Pattern C: Conditional Finality via Notary
+
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.20;
+
+contract ConditionalFinalityHandler {
+    INotaryRegistry public notaryRegistry;
+
+    mapping(bytes32 => bool) public pendingFinalization;
+
+    function executeWithConditionalFinality(
+        bytes32 planId,
+        Step[] calldata steps
+    ) external {
+        // Execute DLT steps
+        // Mark as pending finalization
+        pendingFinalization[planId] = true;
+
+        // Notary must co-sign after bank settlement
+    }
+
+    function finalizeWithNotary(bytes32 planId, bytes calldata notarySignature) external {
+        require(pendingFinalization[planId], "Not pending");
+        require(notaryRegistry.verifyNotarySignature(planId, notarySignature), "Invalid notary signature");
+
+        // Complete finalization
+        pendingFinality[planId] = false;
+    }
+}
+```
+

+
+## 5. Security Considerations
+
+### Access Control
+- Use OpenZeppelin's `Ownable` or `AccessControl` for admin functions
+- Implement multi-sig for critical operations (adapter whitelisting, codehash registration)
+
+### Reentrancy Protection
+- Use `ReentrancyGuard` for execute functions
+- Follow checks-effects-interactions pattern
+
+### Upgradeability
+- Consider using proxy patterns (Transparent/UUPS) for upgradeable contracts
+- Implement timelocks for upgrades
+- Require multi-sig for upgrade approvals
+
+### Codehash Verification
+- Register codehashes for all adapters
+- Verify codehash before execution
+- Prevent execution if codehash doesn't match
+
+### Gas Optimization
+- Batch operations where possible
+- Use `calldata` instead of `memory` for arrays
+- Minimize storage operations
+
+---
+
+## 6. Testing Requirements
+
+### Unit Tests
+- Test each interface function
+- Test error cases (invalid inputs, unauthorized access)
+- Test atomicity (all-or-nothing execution)
+
+### Integration Tests
+- Test full workflow execution
+- Test 2PC prepare/commit/abort flows
+- Test notary integration
+- Test adapter registry whitelisting
+
+### Fuzz Tests
+- Fuzz step configurations
+- Fuzz plan structures
+- Fuzz edge cases (empty steps, large arrays)

+# UI/UX Specification: ISO-20022 Combo Builder v2
+
+## Overview
+This document specifies the user interface and user experience for the Combo Builder v2, which enables users to compose multi-step financial workflows combining DeFi protocols and traditional banking rails (ISO-20022). The UI is inspired by Furucombo's Create page but extends it with compliance overlays, hybrid adapter support, and optional simulation.
+
+## Design Principles
+1. **Composability**: Drag-and-drop interface for building complex financial workflows
+2. **Transparency**: Clear display of compliance status, fees, and execution risks
+3. **Flexibility**: Support for both DeFi and fiat/DTL adapters with selection control
+4. **User Control**: Optional simulation for advanced users, mandatory compliance checks
+5. **Accessibility**: Intuitive for non-developers while providing advanced features
