refactor(ports): standardize service ports to 8000-8017 range and update CORS configurations across all services
- Update CORS allow_origins in blockchain-node app.py and gossip relay.py to use new port logic (8000-8016) - Update coordinator-api config.py and config_pg.py with standardized port ranges and service labels - Update coordinator-api health check script from port 18000 to 8000 - Update geo_load_balancer.py to use configurable host/port (default 0.0.0.0:8017) - Update agent_security.py sandbox

# AITBC Coordinator API Warnings Fix - March 4, 2026
|
||||
|
||||
## 🎯 Issues Identified and Fixed
|
||||
|
||||
### **Issue 1: Circuit 'receipt_simple' Missing Files**
|
||||
|
||||
**🔍 Root Cause:**
|
||||
- Incorrect file paths in ZK proof service configuration
|
||||
- Code was looking for files in wrong directory structure
|
||||
|
||||
**🔧 Solution Applied:**
|
||||
Updated `/home/oib/windsurf/aitbc/apps/coordinator-api/src/app/services/zk_proofs.py`:
|
||||
|
||||
```diff
|
||||
"receipt_simple": {
|
||||
"zkey_path": self.circuits_dir / "receipt_simple_0001.zkey",
|
||||
- "wasm_path": self.circuits_dir / "receipt_simple.wasm",
|
||||
- "vkey_path": self.circuits_dir / "verification_key.json"
|
||||
+ "wasm_path": self.circuits_dir / "receipt_simple_js" / "receipt_simple.wasm",
|
||||
+ "vkey_path": self.circuits_dir / "receipt_simple_js" / "verification_key.json"
|
||||
},
|
||||
```
|
||||
|
||||
**✅ Result:**
|
||||
- Circuit files now found correctly
|
||||
- ZK proof service working properly
|
||||
- Receipt attestation feature active
|
||||
|
||||
---
|
||||
|
||||
### **Issue 2: Concrete ML Not Installed Warning**
|
||||
|
||||
**🔍 Root Cause:**
|
||||
- Concrete ML library not installed (optional FHE provider)
|
||||
- Warning is informational, not critical
|
||||
|
||||
**🔧 Analysis:**
|
||||
- Concrete ML is optional for Fully Homomorphic Encryption (FHE)
|
||||
- System has other FHE providers (TenSEAL) available
|
||||
- Warning can be safely ignored or addressed by installing Concrete ML if needed
|
||||
|
||||
**🔧 Optional Solution:**
|
||||
```bash
|
||||
# If Concrete ML features are needed, install with:
|
||||
pip install concrete-python
|
||||
```
|
||||
|
||||
**✅ Current Status:**
|
||||
- FHE service working with TenSEAL provider
|
||||
- Warning is informational only
|
||||
- No impact on core functionality
|
||||
