Project Status: 🔍 Discovery Ongoing (Phase 1 Active)
Start Date: January 22, 2026
Renamed: January 30, 2026 (from "copilot-instructions" to "foundation-layer")
Current Activity: Pattern extraction engine - captures patterns from implementation projects
Phase 1 Status: IN PROGRESS - Project 06 patterns identified, Project 14 mock testing extracted
Owner: Marco Presta
Establish the EVA Foundation Layer - a comprehensive pattern library for GitHub Copilot instructions, development standards, and reusable architectural patterns across the EVA ecosystem to ensure:
- Consistency: Unified AI assistance behavior across all repositories
- Quality: High-quality code generation aligned with project standards
- Maintainability: Clear documentation and organization of AI context
- Efficiency: Optimized developer productivity through effective Copilot configuration
- Compliance: Adherence to security, coding, and architectural best practices
- Pattern Reuse: Extract patterns from implementation projects (06, 14, 15+) → Foundation layer → All future projects benefit
The EVA Foundation Layer serves as the Pattern Extraction Engine for the EVA ecosystem - capturing successful patterns from implementation projects and making them available to all future work through standardized templates, best practices, and Copilot instructions.
Status: ✅ ESTABLISHED in EVA ecosystem
Priority: HIGHEST - Listed as FIRST item in existing EVA-JP-v1.2 Copilot instructions
Impact: Unicode characters cause UnicodeEncodeError crashes in enterprise Windows cp1252 environments
The Problem:
- Enterprise Windows environments default to cp1252 encoding
- Unicode characters (✓ ✗ ⏳ 🎯 ❌ ✅ …) cause silent automation failures
- These crashes break production systems without clear error messages
The Solution (Already Established in EVA):
# FORBIDDEN - Will crash in Windows enterprise
print("✅ Task complete") # Unicode checkmark crashes
print("❌ Error occurred") # Unicode X crashes
print("⏳ Processing...") # Unicode hourglass crashes
# REQUIRED - ASCII only, enterprise-safe
print("[PASS] Task complete")
print("[FAIL] Error occurred")
print("[INFO] Processing...")Batch File Safety:
@echo off
REM CRITICAL: Windows Enterprise Encoding Safety
set PYTHONIOENCODING=utf-8
echo [INFO] Starting automation...Discovery Insight: This pattern is already well-documented as the CRITICAL priority in EVA-JP-v1.2 Copilot instructions. Project 07's role is ensuring consistent application across all EVA repositories.

Issue 1: PART 1 Extraction Fails
- Symptom: Apply script fails with "Cannot find PART 1 boundary markers"
- Cause: Template format changed or markers corrupted
- Solution:
# Verify template integrity Select-String -Path ".\copilot-instructions-template.md" -Pattern "^## PART 1:" Select-String -Path ".\copilot-instructions-template.md" -Pattern "^## PART 2:" # If missing, re-download template from Project 07
Issue 2: Test Suite Fails (Pester Version)
- Symptom:
Test-Project07-Deployment.ps1throws errors about missing commands - Cause: Pester 3.x installed instead of 5.x
- Solution:
# Uninstall old version Uninstall-Module -Name Pester -Force -AllVersions # Install Pester 5.x Install-Module -Name Pester -MinimumVersion 5.0 -Force -Scope CurrentUser -SkipPublisherCheck # Verify version Get-Module -ListAvailable Pester
Issue 3: Workspace Housekeeping Reports False Positives
- Symptom:
Invoke-WorkspaceHousekeeping.ps1flags valid files as misplaced - Cause: Organization rules in
supported-folder-structure.jsondon't match project conventions - Solution: Customize template for your project:
{ "organizationRules": [ {"pattern": "Deploy-*.ps1", "targetFolder": "scripts/deployment"}, {"pattern": "Test-*.ps1", "targetFolder": "scripts/testing"}, {"pattern": "YourCustomPattern-*.ps1", "targetFolder": "scripts/custom"} ] }
Issue 4: Placeholder Replacement Incomplete
- Symptom: Copilot instructions contain
{PROJECT_NAME}or other placeholders - Cause: Manual deployment without using Apply script
- Solution: Use Apply script for automatic project type detection and placeholder replacement:
.\Apply-Project07-Artifacts.ps1 -TargetPath "I:\MyProject" -DryRun # Preview first
Issue 5: Version Mismatch in Documentation
- Symptom: Copilot instructions say v2.0.0 but template is v2.1.0
- Cause: Old cached copy of template
- Solution: Always use latest template from Project 07:
# Get latest template $templatePath = "I:\EVA-JP-v1.2\docs\eva-foundation\projects\07-foundation-layer\02-design\artifact-templates\copilot-instructions-template.md" # Verify version (should be 2.1.0) Select-String -Path $templatePath -Pattern "^\*\*Version\*\*:"
- Apply Script: Apply-Project07-Artifacts.ps1 (1,396 lines, v1.4.0)
- Test Suite: Test-Project07-Deployment.ps1 (650+ lines, 60+ tests, v1.0.0)
- Usage Guide: template-v2-usage-guide.md
- Workspace Tools: Initialize-ProjectStructure.ps1, Capture-ProjectStructure.ps1, Invoke-WorkspaceHousekeeping.ps1 (v1.0.0)

| Date | Phase | Changes | Author |
|---|---|---|---|
| 2026-01-29 | Development | Self-Referential Copilot Instructions Created: Added .github/copilot-instructions.md (300+ lines) - minimal, self-referential instructions for Project 07 itself. Strategic exception to meta-project nature: demonstrates the patterns it teaches. Features: Critical pattern enforcement (encoding safety, professional components, evidence collection), primary artifact references (template v2.0.0, usage guide, primer script, test suite), self-consistency check process, pattern validation workflow, quality gates checklist. File is intentionally minimal (~300 lines vs. 1,200+ in full template) but comprehensive enough to guide AI assistants working on Project 07. Updated README.md project structure to include new .github/ directory. Project 07 now practices what it preaches - using ASCII-only, following professional patterns, maintaining self-consistency. |
Marco Presta |
| 2026-01-29 | Development | Phase 3 Complete - Deployment Automation: Created Apply-Project07-Artifacts.ps1 (1,200+ lines) - intelligent primer script that embodies Project 07 best practices. Implements PowerShell professional components (DebugArtifactCollectorPS, SessionManagerPS, StructuredErrorHandlerPS). Features: project type detection (RAG/Automation/API/Serverless), smart PART 2 extraction and preservation, timestamped backup creation, Test-DeploymentCompliance validation with 8 compliance checks, compliance reporting with remediation steps, DryRun preview mode, ASCII-only output throughout, evidence collection at operation boundaries. Created Test-Project07-Deployment.ps1 (650+ lines) - comprehensive Pester 5.x test suite with 60+ test cases covering Professional Component Architecture, Encoding Safety Compliance, Standards Validation, Evidence Collection, Project Type Detection, File Operation Safety. Primer is self-demonstrating: uses the same patterns it deploys. Phase 4 testing blocked on Pester version upgrade (3.x → 5.x required). | Marco Presta |
| 2026-01-29 | Design | Phase 2 Complete - Template v2.0.0: Enhanced copilot-instructions-template.md with 1,000+ lines from EVA-JP-v1.2 production file. Added comprehensive TOC with GitHub-style anchors (#critical-encoding--script-safety format), complete working implementations of 4 professional components (DebugArtifactCollector 80 lines, SessionManager 100 lines, StructuredErrorHandler 120 lines, ProfessionalRunner 200 lines), Quick Reference section with critical patterns table, AI Context Management Strategy (5-step process), Azure Services Inventory, Workspace Housekeeping Principles with self-organizing rules, Evidence Collection patterns with timestamped naming. Implemented semantic versioning (v2.0.0) with Release Notes documenting v1.0.0 and v2.0.0. Created template-v2-usage-guide.md (comprehensive usage instructions with 5-step process, placeholder reference, customization examples for RAG/Automation/API/Pipeline projects, validation checklist). Template now production-ready with 1,200+ lines of tested patterns. Phase 3 status changed to READY. | Marco Presta |
| 2026-01-23 | Discovery | Discovery Status Correction: Project 06 analysis complete with comprehensive patterns extracted (Professional Component Architecture, Windows Enterprise Encoding Safety, Evidence Collection Infrastructure). However, broader EVA ecosystem discovery still needed - cannot claim Phase 2 complete without validating patterns across different project types and surveying actual developer pain points. Updated project status to reflect ongoing discovery reality. | Marco Presta |
| 2026-01-23 | Discovery | Initial Pattern Extraction: Created draft design artifacts based on Project 06 analysis including Professional Transformation Methodology (ADR-004), Dependency Management Strategy (ADR-005), and Professional Runner template. These represent initial patterns pending broader validation. | Marco Presta |
| 2026-01-23 | Discovery | Discovery Phase Initiated: Process anti-pattern analysis, current state assessment, and gap analysis documented. Project 06 identified as rich source of professional transformation patterns. Key insight: Need systematic approach to extract and validate patterns across full EVA ecosystem. | Marco Presta |
| 2026-01-22 | Discovery | Project initiated, structure created | Marco Presta |
