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
