## What it is
A set of PHP interfaces and abstractions for caching, extracted from the Symfony framework's cache component. It lets libraries depend on stable, battle-tested caching semantics without coupling to a specific Symfony cache implementation.

## Use cases
- decouple my PHP library from specific cache implementations
- type-hint against a standard caching interface in PHP
- make my package interoperable with Symfony cache
- define cache semantics for third-party cache adapters
- avoid depending on the full Symfony framework just for caching

## When to choose
- you are building a PHP library that needs caching without hard dependencies
- you want interoperability with Symfony's cache component ecosystem
- you need stable interfaces to program against rather than implementations

## When to avoid
- you need an actual cache implementation rather than interfaces
- your project does not use PHP
- you want a framework-agnostic PSR-6/PSR-16 solution only

## Facets
- artifact type: library
- maturity: stable
- function: caching
- domain: developer-tools, web-development
- platform: php
- tags: abstractions, interfaces, interoperability, symfony-contracts, decoupling
