 ## Zero‑downtime (sem queda durante deploy)
 
-Para evitar interrupção perceptível no deploy, habilitamos rollout "start-first" e múltiplas réplicas nos serviços web e Convex. O Traefik continua roteando para as tasks saudáveis enquanto uma task reinicia.
+Para evitar interrupção perceptível no deploy, habilitamos rollout "start-first". Para este projeto, mantemos **1 réplica** (web e Convex) por segurança, pois:
+- O web usa SQLite (Prisma); múltiplas réplicas concorrendo gravação no mesmo arquivo podem causar erros de lock/readonly.
+- O Convex backend self‑hosted não é clusterizado.
 
 O `stack.yml` já inclui:
-- `replicas: 2` para `web` e `convex_backend`.
-- `update_config.order: start-first` + `failure_action: rollback`.
+- `replicas: 1` + `update_config.order: start-first` (Swarm sobe a nova task saudável antes de desligar a antiga).
+- `failure_action: rollback`.
 - `healthcheck` por porta local, garantindo que o Swarm só troque quando a nova task estiver OK.
