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

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

🔧 Configuration Updates

✅ Key Management Path Update

• Modified: apps/blockchain-node/src/aitbc_chain/consensus/keys.py
• Change: Updated default keys_dir from /opt/aitbc/keys to /opt/aitbc/dev
• Reason: Align with development-specific directory for test keys

✅ Consensus Setup Script Update

• Modified: scripts/plan/01_consensus_setup.sh
• Changes:
  • Updated KeyManager default keys_dir to /opt/aitbc/dev
  • Updated mkdir -p command to create /opt/aitbc/dev
• Reason: Consistency with key management path update

📝 Documentation Updates

✅ New Documentation

• tests/docs/TEST_CLEANUP_COMPLETED.md - Comprehensive test cleanup documentation

✅ Updated Documentation

• tests/docs/README.md - Added cleanup section and updated structure
• docs/project/infrastructure/PRODUCTION_ARCHITECTURE.md - Updated to reflect current architecture

🚀 Deployment Notes

Systemd Services

Services are managed via systemd (not custom launchers):

systemctl start aitbc-blockchain-node
systemctl start aitbc-blockchain-rpc
systemctl start aitbc-agent-coordinator

Directory Structure

• Config: /etc/aitbc/
• Services: /opt/aitbc/services/
• Runtime data: /var/lib/aitbc/data/, /var/lib/aitbc/keystore/
• Logs: /var/log/aitbc/

🔄 Migration Guide

For Developers

Before:

# Multiple conftest files
pytest --conftest=conftest_mesh_network.py
# Phase test runner (would fail - phase2 missing)
python tests/run_all_phase_tests.py
# Legacy production scripts
python /var/lib/aitbc/production/blockchain.py

After:

# Single conftest
pytest
# Production test runner
python tests/run_production_tests.py
# Systemd services
systemctl start aitbc-blockchain-node

✅ Quality Metrics

• Test Reduction: 12 unnecessary test/config files removed
• Configuration Clarity: Single conftest.py

Code Quality

• Configuration: Single source of truth for test configuration
• Architecture: Clean separation between source code and runtime data
• Documentation: Comprehensive documentation of changes

🎯 Next Steps

Optional Future Actions
