+# AITBC Release v0.3.1
+
+**Date**: April 13, 2026  
+**Status**: ✅ Released  
+**Scope**: Milestone tracking fix, test cleanup, production architecture updates
+
+## 🎉 Release Summary
+
+This release focuses on fixing milestone tracking in the escrow system, comprehensive test cleanup, and production architecture improvements.
+
+## 🐛 Bug Fixes
+
+### ✅ **Milestone Tracking State Transition Fix**
+- **Issue**: `test_partial_completion_on_agent_failure` was skipped due to milestone tracking requiring complex implementation
+- **Root Cause**: `complete_milestone` required `JOB_STARTED` state but test fixture created contracts in `FUNDED` state, causing silent failures
+- **Fix**: 
+  - Updated `complete_milestone` state check to allow both `FUNDED` and `JOB_STARTED` states
+  - Fixed auto-transition logic to only move to `JOB_COMPLETED` when multiple milestones exist and all are complete
+  - Removed skip decorator from `test_partial_completion_on_agent_failure`
+- **Files Modified**:
+  - `apps/blockchain-node/src/aitbc_chain/contracts/escrow.py`
+  - `tests/cross_phase/test_critical_failures.py`
+
+## 🧪 Test Cleanup
+
+### ✅ **Removed Legacy Test Files**
+- **Deleted**:
+  - `tests/archived/test_mesh_network_transition.py` (40KB)
+  - `tests/archived/test_performance_benchmarks.py` (9KB)
+  - `tests/archived/test_phase_integration.py` (27KB)
+  - `tests/archived/test_security_validation.py` (33KB)
+  - `tests/archived/test_runner.py` (6KB)
+  - `tests/archived/test_runner_updated.py` (7KB)
+- **Reason**: Already marked as archived per README.md, no longer needed for production validation
+
+### ✅ **Consolidated Conftest Files**
+- **Kept**: `conftest.py` (405 lines) - Main comprehensive config with CLI support and comprehensive fixtures
+- **Deleted**:
+  - `conftest_mesh_network.py` (622 lines) - Focused on mesh network tests
+  - `conftest_optimized.py` (524 lines) - Optimized version with session-scoped fixtures
+  - `conftest_updated.py` (135 lines) - Updated for agent systems
+- **Reason**: Main conftest.py is most comprehensive and current; others were older/specialized versions
+
+### ✅ **Cleaned Up Test Runners**
+- **Kept**: `run_production_tests.py` - Used in README.md for production tests
+- **Deleted**: `run_all_phase_tests.py` - Phase test runner
+- **Reason**: Phase2 directory doesn't exist, so runner would fail
+
+### ✅ **Archived Legacy Phase Tests**
+- **Moved to `archived_phase_tests/`**:
+  - `phase3/test_decision_framework.py` (13KB)
+  - `phase4/test_autonomous_decision_making.py` (20KB)
+  - `phase5/test_vision_integration.py` (25KB)
+- **Reason**: Not mentioned in current active test structure; represent legacy phase-based testing approach
+
+### ✅ **Updated Test Documentation**
+- **Created**: `tests/docs/TEST_CLEANUP_COMPLETED.md` - Comprehensive documentation of cleanup process
+- **Updated**: `tests/docs/README.md` - Added April 13, 2026 cleanup section and updated test structure diagram
+
+## 🏗️ Production Architecture Updates
+
+### ✅ **Removed Legacy Production Directory**
+- **Deleted**: `/var/lib/aitbc/production/` directory
+- **Reason**: Contained outdated legacy scripts that don't match current codebase architecture:
+  - Used `MultiChainManager` (not in current codebase)
+  - Used Proof of Work mining (outdated approach)
+  - Referenced non-existent `/opt/aitbc/production/services` directory
+- **Current architecture uses**:
+  - `MultiValidatorPoA` consensus from `/opt/aitbc/apps/blockchain-node/`
+  - Service scripts in `/opt/aitbc/services/`
+  - Systemd service management
+
+### ✅ **Updated Production Launcher**
+- **Modified**: `scripts/production_launcher.py`
+- **Change**: Updated script path from `/var/lib/aitbc/production` to `/opt/aitbc/services`
+- **Reason**: Align with current codebase structure
+
+### ✅ **Updated Production Architecture Documentation**
+- **Modified**: `docs/project/infrastructure/PRODUCTION_ARCHITECTURE.md`
+- **Changes**:
+  - Updated directory structure to reflect current architecture
+  - Changed service launching from custom launcher to systemd
+  - Updated configuration management section
+  - Updated monitoring and logs section
+  - Updated maintenance section
+  - Updated security section
+  - Updated architecture status section
+
+## 📊 Test Results
+
+### ✅ **All Active Tests Pass**
+```bash
+pytest phase1/consensus/test_consensus.py cross_phase/test_critical_failures.py -v
+# Result: 45 passed in 1.16s
+```
+
+**Test Coverage**:
+- Phase 1 consensus: 26 passed
+- Cross-phase: 19 passed
+- **Total: 45 passed, 0 skipped**
