What common mistake do developers make with Convention over repetition, why does the mistake cause problems, and what is the safer approach? One recurring problem with convention over repetition is applying it without understanding the boundary it protects. Treating Laravel as only a template engine instead of an application framework with routing, HTTP, database and service-layer capabilities. In addition, Laravel encourages consistent project conventions for routes, controllers, models, migrations, views and configuration, which reduces duplicated setup code. Safer engineering approach: keep the responsibility in the correct layer, use the framework's supported API, validate and authorize inputs, avoid hidden side effects, and verify the behavior with tests.
