HA scheduler: the job scheduler and alert evaluator hold session-scoped PostgreSQL advisory locks on pinned pool connections — replicas scan for due work exactly once, failover verified live with two replicas. Manual and hook-triggered runs stay available on any replica. Email surface: mailer renders registered templates (invitation); every send is logged to core.email_log with status and error text. New GET /projects/:id/emails endpoint; Members page shows an Email log card.
