[WIP] Build tool for structured error reports collection

[Copilot]

Implementation Plan for Go Error Vault ✅

Core Features Implementation - COMPLETE

• Initialize Go module and project structure
• Implement error report data model (signature, frequency, timestamp)
• Build file-based error collection (watch/read error files)
• Build HTTP API for error submission
• Implement local storage (SQLite-based)
• Create error grouping by signature logic
• Build frequency tracking and trend analysis
• Implement CLI commands (server, submit, list, stats, trends, init)
• Create optional web UI for visualization
• Add configuration file support
• Write tests for core functionality
• Add documentation and usage examples
• Ensure privacy (local-only, no external services)

Additional Enhancements - COMPLETE

• Integration examples (Go, Node.js, Python)
• GitHub Actions CI workflow
• Contributing guidelines
• Demo script for quick testing
• Makefile for easy building
• Code quality tools (golangci-lint config)
• Security scan (0 vulnerabilities)

Summary

Complete error vault implementation with:

✅ Core Functionality

• SQLite local storage with automatic error grouping by signature
• HTTP API (POST /api/errors, GET /api/stats, GET /api/errors/groups, GET /api/errors/trends)
• File-based collection with 5-second polling and automatic archival
• CLI with 7 commands: server, submit, list, stats, trends, init, version
• Web UI with dashboard, error groups, and trend visualization

✅ Developer Experience

• Simple one-command setup: errorvault init && errorvault server
• Client libraries for Go, Node.js, and Python
• Comprehensive documentation with 30+ examples
• Demo script for quick testing
• Makefile with common tasks

✅ Quality & Security

• Unit tests for models and storage (100% pass rate)
• Zero security vulnerabilities (CodeQL scan passed)
• No deprecated APIs
• CI/CD pipeline with multi-version testing
• Code linting configured

✅ Privacy & Architecture

• 100% local data storage (no external services)
• No telemetry or tracking
• Works completely offline
• Simple SQLite database
• Open source (GPL-3.0)

Original prompt

Build a Go tool that collects structured error reports from local apps via files or HTTP. Group errors by signature, track frequency, and display trends. Store data locally and expose a CLI and optional web UI. Focus on developer ergonomics and privacy (no external services).
