Render an unsubscribe confirmation page for a signed token

Audience: application and coding agent.

Coverage and source scope

Anonymous endpoint. GET is preview-safe and never mutates state — it only renders a confirmation page with a POST form. Email link previewers (Outlook, Apple Mail, Gmail) will fetch this URL during scanning; the user must submit POST to actually unsubscribe (RFC 8058).

Failure posture

treat non-2xx responses as contract-aware failures, not free-form errors
preserve requestId and traceparent in logs and downstream reports
if provenance or freshness metadata is present, return it unchanged so trust is not lost in the handoff
