sync endpoint, Santa page in the UI). Problem Approvers should not have to watch the UI. Workshop offers Slack buttons and one-click email approve/deny. Scope • Notify approvers of new requests through existing alert channels (webhook/email). • Signed, single-use, expiring approve/deny links; acting through a link still requires the approver's osctrl session. • Slack interactive buttons as a follow-up if the webhook channel is not enough. Acceptance • Links cannot be replayed or used by another user; expired links fail closed. jmpsec/osctrl
