Explanation

GitHub enforces a 1 MB size limit on the secret_scanning.yml configuration file. If the file reaches or exceeds 1 MB in size, GitHub will silently ignore it entirely - meaning no exclusions or customizations defined in that file will be applied. This limit is a safeguard against oversized configuration files impacting platform performance. Administrators should keep the file well below this threshold to ensure their configurations are honored.
