postinit

Postinit refers to the phase or hook that executes after the initial construction or initialization of a component, object, or system. The purpose is to perform tasks that require the full object graph or environment to be present, such as validating configuration, resolving dependencies, or registering resources.

In programming, post-initialization mechanisms let developers implement behavior that cannot be safely done in a constructor. In Python's dataclasses, for example, a __post_init__ method is called immediately after __init__ to perform additional setup. In Java and other languages, frameworks may provide post-initialization callbacks or annotations such as PostConstruct to run methods after dependency injection or bootstrapping.

In game development and modding, a postinit stage may occur after the core engine and assets are loaded, allowing mods or game systems to register content, apply patches, or finalize state.

In system design, a post-init phase can exist in boot sequences, embedded systems, or service supervision, where tasks that require all services to be present are started after a baseline initialization.

Considerations for postinit include that ordering is critical and can be platform-specific; postinit steps can introduce side effects or cyclic dependencies if not carefully managed. See also post-initialization, __post_init__, and postConstruct where applicable.
