+# Impl: FAB — overlay abre sem foco na busca; fechar não cobre o campo
+
+Status: aprovado
+Atualizado em: 2026-08-02
+Issue: #317
+Intenção: docs/plans/fab-overlay-sem-autofocus-e-fechar.md
+Appetite restante: herdado (~0,5 dia eng)
+
+## Leitura da intenção
+
+- **Outcome:** Ao abrir o FAB, o overlay inicia em estado idle — ações visíveis, busca sem foco. Desktop: X não sobrepõe a busca. Mobile: handle de swipe, sem X.
+- **O que NÃO negociar:** Ritual B132 (foco deliberado na busca ainda recolhe ações); catálogo/lockdown/limpeza de query inalterados; sem migration/Consent/RBAC.
+- **O que reavaliar:** A hipótese de `autoFocus` explícito no input estava errada — o foco vem do trap de foco padrão do Dialog (Radix `onOpenAutoFocus`) e do Drawer (base-ui `initialFocus` default).
+
+## Abordagem recomendada
+
+```mermaid
+flowchart LR
+  FAB[FAB click] --> Open[Overlay opens]
+  Open --> NoFocus[Block open autofocus]
+  NoFocus --> Idle[Idle: actions visible]
+  Idle -->|user taps search| Retract[B132 retract]
+  Open --> Desktop[md+: pr on search + default X]
+  Open --> Mobile[mobile: showSwipeHandle, no X]
+```
+
+**Opções consideradas:**
+
+| Opção | Descrição                                                                                                 | Veredito                                   |
+| ----- | --------------------------------------------------------------------------------------------------------- | ------------------------------------------ |
+| A     | `onOpenAutoFocus` / `initialFocus={false}` no overlay + `md:pr-10` na busca + `showSwipeHandle` no drawer | **Recomendada** — mínima, escopada ao dono |
+| B     | Header dedicado com X em flow no dialog                                                                   | Rejeitada — mais chrome, fora do appetite  |
+| C     | `showCloseButton={false}` + close custom em todo dialog kit                                               | Rejeitada — polui kit global               |
+
+**Recomendação:** A — três props no `CampaignQuickActionsOverlay`, sem alterar `dialog.tsx`/`Drawer.tsx` globalmente.
+
+### Componentes / mudanças
+
+- **`CampaignQuickActionsOverlay`** (`src/components/campaign/shell/CampaignQuickActionsOverlay.tsx`):
+  - Dialog: `onOpenAutoFocus` → `preventDefault` + foco no `DialogTitle` (`titleRef`, padrão B42)
+  - Dialog: `md:pr-10` em `OverlaySearchChrome` (reserva faixa para X `right-3 size-8`)
+  - Drawer: `showSwipeHandle` no `Drawer`; `initialFocus={titleRef}` em `DrawerContent`
+- **Migration:** sem migration
+- **Access / Consent:** N/A
+- **UI:** Impeccable B — polimento do chrome existente
+
+### Dados → forma
+
+N/A
+
+## Fases verificáveis
+
+1. **UI** — props de foco + padding + handle; testes unitários no spec existente
+2. **Gates** — `pnpm gate:fast`; push via `pnpm push`
+
+## Rabbit holes / Não escopo (engenharia)
+
+- Alterar `DialogContent` default global
+- Desligar recolhimento B132 ao focar
+- Redesenhar grade ou catálogo
+
+**Defer (gatilho):** extrair `HomeChromeRetractionShell` compartilhado com `CampaignHomeLayout` quando um 3º chrome retrátil for tocado de novo (já é o 3º — `quick-actions-chrome`; extrair em issue futura, fora do appetite B146).
+
+## Riscos e mitigação
+
+| Risco                                      | Mitigação                                              |
+| ------------------------------------------ | ------------------------------------------------------ |
+| `initialFocus={false}` quebra a11y teclado | Foco no título sr-only (B42), não na busca nem em void |
+| `pr-10` insuficiente em telas estreitas    | `md:` só no breakpoint dialog; mobile usa drawer       |
+
+## Aceite de engenharia
+
+- [x] Aceite de produto da intenção ainda coberto
+- [x] Invariantes AGENTS/engineering-standards
+- [x] Testes unitários previstos em `campaignQuickActionsDrawer.unit.spec.tsx`
