Immutability Laravel Package

repat/immutability is a lightweight Laravel/PHP package for building genuinely immutable objects. Apply the provided trait to a class and its state becomes locked after construction, so any attempt to modify it later is rejected instead of silently corrupting data your application relies on.

It is a natural fit for DTOs, value objects, and configuration data where accidental mutation causes subtle bugs. The package integrates cleanly with Laravel through package auto-discovery and stays out of the way of your existing code.

• Trait-based immutability for any PHP class
• Guard clauses block mutation after construction
• Ideal for DTOs and value objects
• Laravel auto-discovery support
• Simple API with a minimal footprint
