+# Repository Rules
+
+This repository is public and may communicate only with the vendor-neutral Bridge API v1. Never add direct device connections, device credentials, proprietary endpoints, wire fields, status codes, payloads, private fixtures, or protocol-derived mappings.
+
+Use stable bridge IDs for Home Assistant unique IDs, create entities only for reported capabilities, and sanitize diagnostics. Run the configured formatter, linter, type checker, and full test suite for changes.
+
+All source code, comments, tests, UI strings, and documentation must be written in English. Do not add a license, publish a release, or change versions without explicit approval.

+# MB-Secure for Home Assistant
+
+Unofficial local Home Assistant integration for MB-Secure through the vendor-neutral MB-Secure Bridge API.
+
+This public integration never connects directly to the controller and never stores controller credentials. The implementation is currently being developed against a neutral mock bridge.
