## What it is
An Android library providing UnPeekLiveData, a drop-in replacement for SingleLiveEvent that prevents LiveData 'sticky event' data re-push (data backflow) to newly subscribed observers. It supports multiple observers consuming the same message, manual memory cleanup, and read-write separation following the single-source-of-truth principle.

## Use cases
- prevent livedata data backflow on android
- singleliveevent alternative supporting multiple observers
- one-time event distribution in sharedviewmodel
- stop livedata pushing stale data to new subscribers
- android mvvm page communication events
- consume event by multiple fragments without re-delivery

## When to choose
- you use SharedViewModel + LiveData for inter-page communication and hit sticky-event re-push issues
- you need one message consumed by multiple observers before blocking re-delivery
- you want a non-invasive, open-closed SingleLiveEvent replacement in Java

## When to avoid
- you need high-frequency event dispatch (more than ~5 events per second) - the author recommends MVI-Dispatcher instead
- your project uses Kotlin coroutines/Flow where SharedFlow offers a native solution
- you need a license-protected dependency - the project has no license
