Before you connect

Public repositories only

Quarantine uses GitHub OAuth to identify you and list public repositories. This prototype requests no private-repository or write scope.

Retention and revocation: signing out invalidates active Quarantine sessions. Revoking the OAuth grant in GitHub invalidates the credential but does not delete its encrypted database record. Only operator database cleanup deletes that record; this prototype has no self-service account deletion. Use the synthetic demo if you do not want to connect an account.

For private repositories, the safer production path is a GitHub App with repository-level Actions: read access.
