2. Required Interfaces

• caddy.Module: Implemented via CaddyModule() method
• caddy.Provisioner: Implemented via Provision() method
• caddy.Validator: Implemented via Validate() method
• caddyhttp.MiddlewareHandler: Implemented via ServeHTTP() method
• caddyfile.Unmarshaler: Implemented via UnmarshalCaddyfile() method

3. Documentation Requirements

• Struct Documentation: Added detailed documentation for main Middleware struct
• README.md: Comprehensive README with examples and installation instructions
• Module Metadata: Created MODULE.md with standardized module information
• Usage Examples: Created caddyfile.example with practical configuration examples
• API Documentation: Generated via go doc commands

4. Code Quality and Standards

• Go Module Structure: Proper go.mod with correct module path
• Version Consistency: Updated version constant to match latest release (v0.0.6)
• Build Verification: Module builds successfully with go build
• Module Verification: Passes go mod verify
• No Build Errors: Clean compilation with no warnings or errors

5. Release Management

• Git Tags: Proper semantic versioning tags (v0.0.3, v0.0.4, v0.0.5, v0.0.6)
• GitHub Releases: Automated release workflow creating GitHub releases
• Release Notes: Proper release descriptions and changelogs
• Binary Assets: Cross-platform binaries generated for releases

6. Testing and Validation

• Test Suite: Comprehensive test coverage across multiple files

• Module Import: Can be imported and used with xcaddy build

🔍 Potential Issues and Solutions

Issue Analysis: Registration Error ID 2b782e50-057d-4dac-bbd5-4cd1c1188669

Based on the error ID mentioned in the issue comments, this appears to be a server-side error during the registration process rather than a module compliance issue. Common causes and solutions:

1. Server-Side Registration Issues

• Cause: Temporary issues with the Caddy module registration service
• Solution: Retry registration after some time
• Status: May resolve automatically

2. Module Path Validation

• Cause: Registration service may have strict validation rules
• Solution: Ensure github.com/fabriziosalmi/caddy-waf is accessible and properly formatted
• Status: ✅ Module path is valid and accessible

3. Go Module Accessibility

• Cause: Registration service needs to fetch and validate the module
• Solution: Ensure module is publicly accessible and properly tagged
• Status: ✅ Repository is public with proper tags

4. Caddy Version Compatibility

• Cause: Module might require specific Caddy version
• Solution: Verify compatibility with latest Caddy version
• Status: ✅ Uses Caddy v2.9.1 (latest)

🚀 Next Steps for Registration

1. Retry Registration

• Visit https://caddyserver.com/account/register-package
• Use the exact module path: github.com/fabriziosalmi/caddy-waf
• Ensure using the latest tag: v0.0.6

2. Contact Caddy Team

• If registration continues to fail, contact Caddy maintainers
• Provide the error ID: 2b782e50-057d-4dac-bbd5-4cd1c1188669
• Reference this module's compliance with all requirements

3. Alternative Registration Paths

• Consider submitting a PR to the Caddy Community repository
• Engage with the Caddy community on forums or Discord
• Document the module in community wikis or resources

📋 Final Verification Commands

Run these commands to verify module readiness:

# Verify module builds successfully
go build -v

# Verify module interfaces
go doc -short

# Test module import
go list -m github.com/fabriziosalmi/caddy-waf

# Verify with xcaddy (if available)
xcaddy build --with github.com/fabriziosalmi/caddy-waf

# Check latest version/tag
git describe --tags --abbrev=0
