+# Rate Limiting Implementation Guide
+
+## Overview
+
+Rate limiting has been implemented for AITBC API endpoints to prevent abuse and ensure fair resource allocation. This guide explains how to apply rate limiting to FastAPI routers.
+
+## Infrastructure
+
+### Rate Limiting Module
+
+Location: `/opt/aitbc/aitbc/rate_limiting.py`
+
+The module provides:
+- `@rate_limit()` decorator for endpoint-level rate limiting
+- `RateLimitMiddleware` for global middleware-based rate limiting
+- Helper functions for managing rate limiters
+
+### Rate Limiter Implementation
+
+The underlying `RateLimiter` class in `aitbc/security_hardening.py` implements a token bucket algorithm.
+
+## Applying Rate Limiting to Routers
+
+### Step 1: Import the decorator
+
+```python
+from fastapi import Request
+from aitbc.rate_limiting import rate_limit
+```
+
+### Step 2: Add Request parameter
+
+Add `request: Request` as the first parameter (after any path parameters) to each endpoint:
+
+```python
+@router.post("/workflows")
+async def create_workflow(
+    request: Request,  # Add this
+    workflow_data: AgentWorkflowCreate,
+    session: Session = Depends(...),
+    current_user: str = Depends(...),
+):
+    ...
+```
+
+### Step 3: Apply the decorator
+
+Add the `@rate_limit` decorator before the endpoint:
+
+```python
+@router.post("/workflows")
+@rate_limit(rate=100, per=60)  # 100 requests per minute
+async def create_workflow(
+    request: Request,
+    workflow_data: AgentWorkflowCreate,
+    session: Session = Depends(...),
+    current_user: str = Depends(...),
+):
+    ...
+```
+
+### Rate Limit Guidelines
+
+Recommended rate limits by endpoint type:
+
+- **Write operations** (POST, PUT, DELETE): 50-100 requests per minute
+- **Read operations** (GET): 200-500 requests per minute
+- **Health/test endpoints**: 1000 requests per minute
+- **Execution/long-running operations**: 50 requests per minute
+
+### Example: Complete Router
+
+See `/opt/aitbc/apps/coordinator-api/src/app/routers/agent_router.py` for a complete example.
+
+## Custom Rate Limiting
+
+### Custom Key Function
+
+To rate limit by something other than IP address (e.g., API key, user ID):
+
+```python
+def custom_key(request: Request) -> str:
+    return request.headers.get("X-API-Key", "unknown")
+
+@router.post("/endpoint")
+@rate_limit(rate=100, per=60, key_func=custom_key)
+async def endpoint(request: Request, ...):
+    ...
+```
+
+### Custom Error Message
+
+```python
+@router.post("/endpoint")
+@rate_limit(rate=100, per=60, error_message="Custom limit message")
+async def endpoint(request: Request, ...):
+    ...
+```
+
+## Global Middleware
+
+For global rate limiting across all endpoints, use the middleware:
+
+```python
+from aitbc.rate_limiting import RateLimitMiddleware
+
+app.add_middleware(
+    RateLimitMiddleware,
+    rate=100,
+    per=60
+)
+```
+
+## Testing
+
+Rate limiting tests are in `/opt/aitbc/tests/test_rate_limiting.py`.
+
+Run tests:
+```bash
+python3 -m pytest -c /dev/null --rootdir "$PWD" --import-mode=importlib tests/test_rate_limiting.py -v
+```
+
+## Remaining Work
+
+There are 70+ router files across the codebase. The following routers need rate limiting applied:
+
+### Coordinator-API (50+ routers)
+- `/opt/aitbc/apps/coordinator-api/src/app/routers/*.py`
+- `/opt/aitbc/apps/coordinator-api/src/app/contexts/*/routers/*.py`
+
+### Other Services
+- `/opt/aitbc/apps/agent-coordinator/src/app/routers/*.py`
+- `/opt/aitbc/apps/pool-hub/src/app/routers/*.py`
+- `/opt/aitbc/apps/agent-management/src/app/routers/*.py`
+- `/opt/aitbc/apps/blockchain-node/src/aitbc_chain/rpc/router.py`
+- `/opt/aitbc/apps/exchange/*.py`
+- `/opt/aitbc/apps/wallet/src/app/api_rest.py`
+
+## Priority Order
+
+1. **High Priority**: Public-facing APIs (coordinator-api, exchange, wallet)
+2. **Medium Priority**: Internal service APIs (agent-coordinator, pool-hub)
+3. **Low Priority**: Admin/management APIs

+   - 91 files over 500 lines, largest at 2,000 lines
+   - Needs decomposition into bounded-context services
+   - ✅ Phase 1 Complete: Agent Coordination bounded context decomposed
+     - Created app/services/agent_coordination/ package with 8 modules
+     - Migrated agent_integration.py (1159 lines) and 7 other agent-related files

+     - Import tests verified successfully
+     - Old monolithic files removed
+   - ✅ Phase 5 Complete: Compliance & Security bounded context decomposed
+     - Created app/services/compliance_security/ package with 2 modules
+     - Migrated compliance_engine.py (34K) and audit_logging.py (20K)
+     - Updated imports within package (audit.py import updated to use relative path)
+     - No external imports to update across coordinator-api
+     - Import tests verified successfully
+     - Old monolithic files removed
+   - ✅ Phase 6 Complete: Cross-chain Operations bounded context decomposed
+     - Created app/services/cross_chain/ package with 3 modules

+     - Old monolithic files removed
+   - ✅ All 6 phases complete: 25+ large service files migrated to bounded-context packages
+     - Reduced monolithic services directory by ~200K lines of code
+     - Maintained backward compatibility through lazy-loading pattern
+     - All import tests passed successfully
+
+2. **Production Code Using print()** (HIGH IMPACT)
+   - 925 print() statements in production code
+   - Bypasses structured logging, makes log aggregation impossible
+   - Highest-impact quick win
+   - ✅ Replaced print() with logger in high-priority production code (coordinator-api/src, agent-coordinator/src)
+   - ✅ Replaced print() with logger in medium-priority code (apps/exchange, scripts)
+   - Remaining print() statements in low-priority files (tests, demos) - acceptable for test output and demo scripts
+
+3. **Potentially Hardcoded Secrets** (SECURITY)
+   - 49 hardcoded credentials remain in TEST FILES ONLY (admin123, operator123, user123)
+   - Production config.py verified: no secret_key defaults
+   - No .env.example file exists (removed as claimed)
+   - Test fixtures acceptable with hardcoded credentials for integration tests
+
+4. **Bare Except Clauses** (RELIABILITY)
+   - 21 bare except clauses
+   - FIXED: Replaced with `except Exception:` across 12 files
+   - Catches SystemExit/KeyboardInterrupt, hides real errors
+   - Makes system unkillable in failure scenarios

+# AITBC Feature Gap Roadmap
+
+**Status**: Living Document  
+**Last Updated**: 2026-05-18  
+**Commit**: `45556e9c`  
+
+---
+
+## Executive Summary
+
+The AITBC platform is architecturally complete with all services running, but functionally incomplete. The platform has **35+ feature contexts** in the coordinator API, **4 external services** (wallet, blockchain-node, marketplace, edge-api), and **264+ registered routes** — but many endpoints are stubs returning 200 with empty/mock data.
+
+### Service Health Overview
+
+| Service | Port | Routes | Working | Stubbed | Status |
+|---------|------|--------|---------|---------|--------|
+| Coordinator API | 8011 | 264+ | ~85% | ~15% | ✅ Mostly Working |
+| Wallet Service | 8015 | 12 | 12 | 0 | ✅ Working |
+| Blockchain Node | 8006 | 20+ | 20 | 0 | ✅ Working |
+| Marketplace | 8102 | 15 | 15 | 0 | ✅ Working |
+| Edge API | 8103 | 30 | 25 | 5 | ✅ Mostly working |
+| AI Engine | 8013 | 8 | 8 | 0 | ✅ Working |
+| GPU Service | 8014 | 10 | 8 | 2 | ✅ Working |
+
+### Critical Decision Point
+
+**The platform needs real blockchain integration** — currently wallets are SQLite-only and transactions are mock-signed. Without this, users cannot:
+- Create on-chain wallets
+- Send/receive tokens
+- Stake or participate in consensus
+- Execute real DeFi operations
+
+---
+
+## Critical Blockers (Cannot Use Platform)
+
+These 8 gaps prevent any meaningful use of the platform:
+
+### 1. No Real Blockchain Wallet Creation
+
+| Aspect | Current | Required | Effort |
+|--------|---------|----------|--------|
+| **Problem** | Wallets stored in SQLite only; no on-chain addresses | Real key generation + address registration on blockchain | Medium |
+| **Impact** | Users can't receive tokens or interact with contracts | Full wallet lifecycle management | High |
+| **Files** | `apps/wallet/src/app/keystore/persistent_service.py` | Needs blockchain RPC integration | |
+| **Scenarios Blocked** | S01, S02, S14, S26 | | |
+
+**Technical Details**:
+- `create_wallet()` generates keys but doesn't register on chain
+- Address derivation exists but no blockchain account creation
+- Wallet addresses are not indexed by the blockchain node
+
+**Implementation Path**:
+1. Add blockchain RPC call to `register_account(address)` in wallet creation flow
+2. Ensure blockchain node indexes the new account
+3. Update wallet service to track on-chain balance separately from off-chain
+
+---
+
+### 2. No Transaction Signing/Execution
+
+| Aspect | Current | Required | Effort |
+|--------|---------|----------|--------|
+| **Problem** | `sign()` returns fake base64; no real ECDSA | Real transaction signing + broadcast | High |
+| **Impact** | Can't send tokens, stake, or call contracts | Full transaction lifecycle | Critical |
+| **Files** | `apps/wallet/src/app/keystore/persistent_service.py` | Needs secp256k1 signing | |
+| **Scenarios Blocked** | S02, S14, S15, S20, S27, S47 | | |
+
+**Technical Details**:
+- `sign_transaction()` exists but returns mock signature
+- No integration with blockchain node's transaction pool
+- Transaction nonce management not implemented
+
+**Implementation Path**:
+1. Implement `sign_transaction_ecdsa()` using secp256k1
+2. Add transaction broadcast to blockchain RPC
+3. Implement nonce tracking per address
+4. Add transaction receipt polling
+
+---
+
+### 3. No Mining/Block Production
+
+| Aspect | Current | Required | Effort |
+|--------|---------|----------|--------|
+| **Problem** | Chain exists but doesn't produce new blocks | Working PoA consensus with block production | High |
+| **Impact** | Transactions never confirm; state never advances | Continuous block production | Critical |
+| **Files** | `apps/blockchain-node/src/aitbc_chain/consensus/poa.py` | Needs proposer election | |
+| **Scenarios Blocked** | S13 | | |
+
+**Technical Details**:
+- PoA consensus code exists but proposer logic incomplete
+- Blocks can be created manually but not auto-produced
+- No staking-based validator election
+
+**Implementation Path**:
+1. Implement proposer election based on stake
+2. Add block production loop with configurable interval
+3. Ensure transactions are included in blocks
+4. Add reward distribution to validators
+
+---
+
+### 4. No Real AI Job Execution

+
+**Implementation Path**:
+1. Deploy bridge contracts on both chains
+2. Implement token locking on source chain
+3. Implement minting on destination chain
+4. Build relayer daemon for proof transmission
+5. Add fraud proof / dispute window
+
+---
+
+### 7. No IPFS Integration
+
+| Aspect | Current | Required | Effort |
+|--------|---------|----------|--------|

+| **Impact** | Can't secure the network or earn rewards | Full staking contract | High |
+| **Files** | `apps/coordinator-api/src/app/contexts/staking/` | Needs contract deployment | |
+| **Scenarios Blocked** | S14, S26 | | |

+## Testing Strategy
+
+### Per-Feature Checklist
+
+Before marking any feature "working":
+
+1. **Unit Tests**: Core logic tested in isolation
+2. **Integration Tests**: Service-to-service communication
+3. **End-to-End Tests**: Full user flow (CLI → API → Blockchain)
+4. **Multi-Node Tests**: All 3 nodes (genesis, aitbc1, gitea-runner)
+5. **Documentation**: Updated with working examples
+
+### Scenario Coverage
+
+Each scenario should have automated test:
+
+```bash
+# Run specific scenario test
+./scripts/workflow/44_comprehensive_multi_node_scenario.sh --scenario S01
+
+# Or run scenario directly via CLI
+aitbc-cli scenario run S01 --verify
+```

+## Notes
+
+### Recently Fixed (2026-05-18)
+
+1. **Edge-api datetime timezone** - Changed to `datetime.utcnow()`
+2. **Edge-api SQLAlchemy enum** - Added `values_only=True`
+3. **Island status mapping** - Maps "joined" → "active" for PostgreSQL
+4. **Wallet deadlock** - Fixed `create_wallet()` lock issue
+5. **Blockchain balance** - Added `session.flush()` after updates
+6. **ZK test mode** - Added `test_mode` parameter
+
+### Known Working Configurations
+
+- **Islands**: Full CRUD via coordinator proxy → edge-api
+- **GPU Metrics**: All endpoints functional
+- **Marketplace Read**: Offers, bids, stats working
+- **Agent Identity**: Registration and verification working
+
+### Next Immediate Actions
+
+1. Implement `register_account()` in wallet service
