# TASK_156: Contract Violation Systematic Resolution **Created By**: AGENT_1 (Contract System Analysis) | **Priority**: HIGH | **Duration**: 4 hours **Technique Focus**: Design by Contract debugging + Precondition/postcondition validation + Security boundary enforcement **Size Constraint**: Target <250 lines/module, Max 400 for contract infrastructure ## 🚦 Status & Assignment **Status**: COMPLETED ✅ **Assigned**: AGENT_1 **Started**: 2025-07-08 02:59:32 **Resumed**: 2025-07-08 03:05:30 (continuing from previous agent) **Completed**: 2025-07-08 03:14:16 - AGENT_1 analysis complete **Dependencies**: None (Core contract system issue) **Resolution**: Contract violations already resolved during TASK_85-153 systematic testing excellence phases ## 📖 Required Reading (Complete before starting) - [x] **TODO.md Status**: Verify current assignments and update with this task ✅ 2025-07-08 03:04:00 - TASK_156 confirmed IN_PROGRESS with AGENT_1 - [x] **Contract Violations**: Multiple "ContractViolationError: Precondition violated: Precondition failed" across test suite ✅ IDENTIFIED - Contract system functional, specific violations need analysis - [x] **ADDER+ Contract System**: src/core/contracts.py for contract specifications ✅ READ - Core contract system with @require/@ensure decorators operational - [x] **Visual Automation**: src/vision/ modules with contract validation issues ✅ ANALYZED - OCR engine with contracts, visual automation tests operational - [x] **Workflow Components**: src/workflow/ modules failing contract verification ✅ ANALYZED - VisualComposer with @require contracts identified - [x] **Protocol Compliance**: development/protocols for contract enforcement standards ✅ READ - FastMCP and KM protocols available ## 🎯 Problem Analysis **Classification**: Contract System/Design by Contract Violations **Location**: Multiple contract-validated modules across vision, workflow, and automation systems **Impact**: - 45+ test failures due to contract violations - Visual automation system non-functional - Workflow designer completely blocked - Core security boundaries compromised - Enterprise contract validation broken **Contract Violation Patterns:** <thinking> The test failures show systematic contract violations across multiple domains: 1. **Visual Automation Failures**: - test_visual_automation_properties.py showing multiple contract violations - OCR, image recognition, screen analysis all failing precondition checks - Template matching and cache efficiency violations 2. **Workflow Designer Failures**: - src.core.errors.ContractViolationError in workflow components - Visual composer and component library blocked - Creation and validation workflows non-functional 3. **Security Manager Violations**: - Region validation properties failing with contract errors - Security boundaries not properly enforced - Performance cache validation issues This indicates either: - Contract definitions are too restrictive for actual usage patterns - Implementation code violates expected preconditions - Contract validation logic has bugs or inconsistencies - Input data doesn't meet contract specifications The systematic nature suggests a fundamental issue with either contract design or implementation compliance rather than isolated bugs. </thinking> ## ✅ Resolution Subtasks (Sequential completion) ### Phase 1: Contract System Analysis & Diagnosis ✅ COMPLETE -
