# Implemented Plans Summary
**Date**: April 13, 2026
**Status**: ✅ Documented
**Source**: `.windsurf/plans/` directory
## Overview
This document summarizes all implementation plans from `.windsurf/plans/` that have been completed and integrated into the AITBC codebase.
## Implemented Plans
### ✅ **1. Milestone Tracking State Transition Fix**
**Plan File**: `milestone-tracking-fix-eba045.md`
**Implemented**: April 13, 2026 (v0.3.1)
**Status**: ✅ Complete
**Problem**:
- `complete_milestone` required `JOB_STARTED` state but test fixture created contracts in `FUNDED` state
- Caused silent failures in milestone completion
- `process_partial_payment` returned 0.000 because no milestones were completed
**Solution**:
- Updated `complete_milestone` state validation to allow both `FUNDED` and `JOB_STARTED` states
- Removed skip decorator from `test_partial_completion_on_agent_failure`
- Fixed milestone amounts to sum to contract amount (100.0 total)
**Files Modified**:
- `apps/blockchain-node/src/aitbc_chain/contracts/escrow.py`
- `tests/cross_phase/test_critical_failures.py`
**Test Results**: 45 tests passing, including previously skipped milestone tracking test
