The free Action runs inside your GitHub runner and sends no repository code to SunsetPR or an external AI model. Eligible repairs are bot-created drafts and never auto-merge.
Do not email source code, secrets, environment values, customer names, or private repository URLs.
Provider documentation remains the source of truth. Static analysis cannot resolve remote configuration or arbitrary runtime expressions; those remain explicitly unconfirmed.
