CodeIgniter Architecture Patterns

Goal

Keep the codebase maintainable with consistent project patterns.

Do

• Follow a predictable feature layout across controllers, models, views, language files, and tests.
• Separate read models, write workflows, and cross-cutting concerns such as authorization and logging.
• Centralize shared behavior in base services/helpers instead of duplicating per module.
• Prefer explicit dependency boundaries over hidden global state.

Checks

• Feature logic can be traced without jumping across unrelated layers.
• New code matches folder and naming conventions used by existing modules.
• Refactors preserve public routes and response formats unless explicitly changed.
