Development Branch
+##
Repository Purpose
-⚠️ **This is the `develop` branch**
+This repository provides a lightweight PHP runtime abstraction layer that wraps native PHP functionality into clean, consistent, and deterministic APIs.
-- Unstable
-- APIs may change without notice
-- Not intended for production use
+Its purpose is to reduce boilerplate and standardize common execution patterns across the FireHub ecosystem by offering ergonomic helper classes for arrays, strings, files, environment access, and other low-level runtime operations.
-##
Branch Purpose
+It is strictly focused on execution-level concerns and does not contain domain logic, business rules, or framework-level orchestration. It exists to improve developer productivity while preserving native PHP behavior and ensuring zero framework coupling.
-The `develop` branch is the **primary integration branch** for all ongoing development.
+##
Security
-It serves as the staging area where:
-- Feature branches are merged
-- Bug fixes are integrated
-- Experimental work is stabilized
-- Code is prepared for upcoming releases
+For security reporting and guidelines, please refer to our [SECURITY.md](https://github.com/The-FireHub-Project/.github/blob/master/.github/SECURITY.md) file.
-All **release branches** are created **from `develop`**.

Community
-## Stability Guarantee

-❌ No backward compatibility guarantee
-❌ APIs may change without notice
-❌ Behavior may be incomplete or inconsistent
-❌ Breaking changes are expected
