+ * Each method names a real lifecycle email but currently only logs and no-ops.
+ * The lifecycle (status transitions + the daily cron) drives these calls; when
+ * a provider is wired up later, only the bodies here change — every call site
+ * stays the same. Methods are async so the future real implementation (an HTTP
+ * send) is a drop-in without touching callers.
