## What it is
A thin PHP assertion library providing assertions and guard methods for input validation in business models, libraries, and low-level application code. Failed assertions throw exceptions, eliminating the need for verbose if-clause validation code.

## Use cases
- validate function arguments in php
- assert preconditions in business model
- throw exception on invalid input instead of if checks
- guard methods for library input validation
- check file exists and value is digit in php
- lightweight alternative to symfony validator

## When to choose
- you need fast, low-level, dependency-free input assertions in PHP
- you want exception-based validation without instantiating validator objects
- you are writing business-model or library code needing pre/post-condition checks

## When to avoid
- you need filtering or sanitization, not just validation
- you need localized validation messages or complex validation rules
- you are not working in PHP

## Facets
- artifact type: library
- maturity: stable
- function: testing, error-handling
- domain: developer-tools, web-development, backend
- platform: php
- tags: assertions, input-validation, guard-clauses, preconditions, php-library
