## What it is
A thin PHP library that wraps deprecation notification strategies, supporting trigger_error(E_USER_DEPRECATED), PSR-3 logging, and silent tracking. It is side-effect free by default and deduplicates deprecation messages to reduce overhead.

## Use cases
- manage deprecation warnings in a php library
- route deprecation notices to a psr-3 logger
- track how often deprecated apis are triggered
- suppress specific deprecations or whole packages
- trigger deprecations only for external callers

## When to choose
- you maintain a php library and need a dependency-light deprecation mechanism
- you want deprecations collected without relying on global error handler state
- you need deduplication and counting of triggered deprecations

## When to avoid
- you need a general-purpose logging solution rather than deprecation handling
- your project does not use php or composer

## Facets
- artifact type: library
- maturity: stable
- function: logging, error-handling, developer-tools
- domain: developer-tools
- platform: php, cross-platform
- tags: deprecations, psr-3, trigger-error, doctrine, php, libraries
