Implements Phase 1 Foundation with all core services: Core Components: - Configuration management with GONDULF_ environment variables - Database layer with SQLAlchemy and migration system - In-memory code storage with TTL support - Email service with SMTP and TLS support (STARTTLS + implicit TLS) - DNS service with TXT record verification - Structured logging with Python standard logging - FastAPI application with health check endpoint Database Schema: - authorization_codes table for OAuth 2.0 authorization codes - domains table for domain verification - migrations table for tracking schema versions - Simple sequential migration system (001_initial_schema.sql) Configuration: - Environment-based configuration with validation - .env.example template with all GONDULF_ variables - Fail-fast validation on startup - Sensible defaults for optional settings Testing: - 96 comprehensive tests (77 unit, 5 integration) - 94.16% code coverage (exceeds 80% requirement) - All tests passing - Test coverage includes: - Configuration loading and validation - Database migrations and health checks - In-memory storage with expiration - Email service (STARTTLS, implicit TLS, authentication) - DNS service (TXT records, domain verification) - Health check endpoint integration Documentation: - Implementation report with test results - Phase 1 clarifications document - ADRs for key decisions (config, database, email, logging) Technical Details: - Python 3.10+ with type hints - SQLite with configurable database URL - System DNS with public DNS fallback - Port-based TLS detection (465=SSL, 587=STARTTLS) - Lazy configuration loading for testability Exit Criteria Met: ✓ All foundation services implemented ✓ Application starts without errors ✓ Health check endpoint operational ✓ Database migrations working ✓ Test coverage exceeds 80% ✓ All tests passing Ready for Architect review and Phase 2 development. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

0004. Configuration Management Strategy
Date: 2024-11-20
Status
Accepted
Context
We need a consistent approach to configuration management that is simple, clear, and follows industry standards. The system requires configuration for database, email, secrets, and various runtime parameters.
Decision
We will use environment variables with the GONDULF_ prefix for all configuration:
- All environment variables must start with
GONDULF_to avoid namespace collisions - Use uppercase with underscores for word separation
- Follow standard naming patterns (e.g.,
_URLfor connection strings,_KEYfor secrets) - Provide sensible defaults where possible
- Use a single
.env.examplefile to document all available configuration
Standard variables:
GONDULF_SECRET_KEY=<required - no default>
GONDULF_DATABASE_URL=sqlite:///./data/gondulf.db
GONDULF_SMTP_HOST=localhost
GONDULF_SMTP_PORT=587
GONDULF_SMTP_USERNAME=
GONDULF_SMTP_PASSWORD=
GONDULF_SMTP_FROM=noreply@example.com
GONDULF_SMTP_USE_TLS=true
GONDULF_TOKEN_EXPIRY=3600
GONDULF_LOG_LEVEL=INFO
GONDULF_DEBUG=false
Consequences
Positive
- Clear namespace prevents collision with other applications
- Standard environment variable pattern familiar to developers
- Easy to configure in various deployment scenarios (Docker, systemd, etc.)
.env.exampleprovides self-documentation
Negative
- Slightly longer variable names
- Must maintain
.env.examplealongside actual configuration
