Workers emit a WorkerHealth event every 30s with assigned mailbox count, IMAP IDLE connections, memory, goroutines, and rolling 1h send/bounce/ complaint/auth-error/rate-limit counters. Consumer writes them to worker_health_samples. Schema additions on workers: egress_kind (cold_smtp / oauth_api / warmup_only), health_state (healthy / watch / throttled / quarantined / blocked), load_score (weighted utilization). worker_capacity_view aggregates the latest hour of samples into a per-worker capacity row used by the assignment loop. Effective capacity = base_ceiling(egress_kind) × health_multiplier × age_ramp_multiplier so a fresh worker earns its way up to base capacity over 72h, and a worker with rising bounces or complaints automatically gets less load. MailboxWeight returns 1.0 for cold_smtp, 0.05 for Gmail/Graph API (worker IP doesn't matter), 0.4 for warmup-only. AssignWorkerToEmail resolves the mailbox's weight and SelectSharedWorker filters by headroom + sorts by utilization, so a 200-mailbox OAuth worker and a 16-mailbox cold worker balance fairly. UnassignWorkerFromEmail refunds the load_score symmetrically.
