+# Impl: Motivo opcional — tendência (wizard) + nível; remover voltar atrás do DB (B134)
+
+Status: aprovado
+Atualizado em: 2026-08-02
+Issue: #288
+Intenção: docs/plans/motivo-opcional-tendencia-e-nivel.md
+Appetite restante: herdado (~1 dia eng)
+
+## Leitura da intenção
+
+- **Outcome:** staff grava tendência ou nível sem texto obrigatório; Motivo permanece opcional nos dois ritos; `reversalSignals` some da UI, write path e snapshots persistidos.
+- **O que NÃO negociar:** histerese/override/choque triangulado intactos; `leader` lockdown; sem auto-save no nível; motivo vazio grava `null` (não preserva anterior); dados históricos de `reversalSignals` apagados do DB.
+- **O que reavaliar:** não há coluna dedicada — `reversalSignals` vive só no JSON `allocation_decision.snapshot`; migration é data-only, sem alterar `AllocationDecision` config.
+
+## Abordagem recomendada
+
+```mermaid
+flowchart LR
+  UI[Popover / wizard] --> schema[municipalityEngagementLevelSchema]
+  schema --> action[setMunicipalityEngagementLevelRecord]
+  action --> mun[municipality.levelNote nullable]
+  action --> ad[allocationDecision snapshot sem reversalSignals]
+  mig[migration SQL] --> ad
+```
+
+**Opções consideradas:** A remover só da UI/schema | B migration JSON strip + schema/UI/action  
+**Recomendação:** B — aceite exige apagar do banco, não só esconder.  
+**Rejeitadas:** A (órfãos no snapshot); tornar `rationale` opcional na collection (escopo desnecessário — string vazia basta quando motivo ausente).
+
+### Componentes / mudanças
+
+- **`municipalityEngagementLevelSchema`** (`src/lib/schemas/municipality.ts`): `note` → `trimmedNullableText`; remover `reversalSignals`.
+- **`setMunicipalityEngagementLevelRecord`** (`actions/municipality.ts`): snapshot sem `reversalSignals`; `rationale: note ?? ''`.
+- **`MunicipalityListLevelControl`**: um campo Motivo (opcional); `canSubmit` só exige movimento + override quando violações.
+- **`WizardTrendNoteStep`**: remover `required`; label com “(opcional)”.
+- **Migration:** `20260802_*_strip_engagement_reversal_signals` — `UPDATE allocation_decision SET snapshot = snapshot - 'reversalSignals' WHERE …`.
+- **Access / Consent:** inalterado (`canManageMunicipalityEngagementLevel`).
+
+### Dados → forma
+
+- Tendência: schema já usa `trimmedNullableText` — só UI wizard tinha `required` HTML.
+- Nível: `levelNote` nullable no município; `allocationDecision.rationale` string (vazia se sem motivo).
+
+## Fases verificáveis
+
+1. **Schema+server** — schema, action, migration, int test com motivo vazio + snapshot sem reversalSignals.
+2. **UI** — labels “(opcional)”, remover segundo textarea.
+3. **Gates** — `pnpm gate:fast`; push via `pnpm push`.
+
+## Rabbit holes / Não escopo (engenharia)
+
+- Alterar copy do glossário `campaignIntelligenceConcepts` (prosa conceitual, não o campo).
+- `rationale` required na collection — string vazia, não relaxar schema Payload.
+
+## Riscos e mitigação
+
+- **Rationale vazio rejeitado pelo Payload:** int test com `note` omitido; se falhar, usar `''` explicitamente (textarea required aceita vazio).
+- **Migration idempotente:** operador JSONB `-` só onde chave existe; log de row count.
+
+## Aceite de engenharia
+
+- [x] Aceite de produto da intenção ainda coberto
+- [x] Invariantes AGENTS/engineering-standards
+- [x] Testes de domínio previstos (int engagement level + migration unit)

+# Impl: Sidebar — entrada para Organizações
+
+Status: aprovado
+Atualizado em: 2026-08-02
+Issue: #313
+Intenção: docs/plans/sidebar-organizacoes.md
+Appetite restante: ~0,25 dia eng (um item de nav; sem migration)
+
+## Leitura da intenção
+
+- **Outcome:** Staff (coordenador, assessor, candidato) descobre `/campanha/organizacoes` pela sidebar desktop e Sheet mobile; liderança não vê o item; destino ativo em lista, detalhe e `/nova`.
+- **O que NÃO negociar:** lockdown de `leader`; não redesenhar sidebar; não duplicar lista; href canônico `/campanha/organizacoes`.
+- **O que reavaliar:** hipótese de importar `ORGANIZATIONS_LIST_PATH` — `nav.ts` usa literais (precedente Conceitos) para não puxar módulos ao client bundle; manter literal.
+
+## Abordagem recomendada
+
+```mermaid
+flowchart LR
+  staffNav["staffNav + Organizações"] --> getCampaignNav
+  getCampaignNav --> CampaignSidebar
+  getCampaignNav --> MobileSheet["Sheet mobile"]
+  isCampaignNavActive --> Active["lista / slug / nova"]
+```
+
+**Opções consideradas:** A) item após Lideranças | B) após Dobradinhas | C) antes de Apoiadores  
+**Recomendação:** **A** — afinidade domínio orgs ↔ lideranças; alinhado à recomendação da intenção.  
+**Rejeitadas:** B/C — sem ganho de descoberta; A é o modelo mental acordado.
+
+### Componentes / mudanças
+
+- **`staffNav`** (`src/components/campaign/shell/nav.ts`): inserir `{ title: 'Organizações', href: '/campanha/organizacoes', icon: LandmarkIcon }` logo após Lideranças; import `LandmarkIcon` de lucide-react (instituições — distinto de `HandshakeIcon` e `Building2` usado em município no dashboard).
+- **Migration:** sem migration
+- **Access / Consent:** nenhum — `getCampaignNav` já exclui `leader`; staff vê por default (mesmo que Lideranças/Demandas)
+- **UI:** Impeccable B — encaixe no shell existente; `CampaignSidebar` e Sheet já consomem `getCampaignNav`; `isCampaignNavActive` já cobre paths aninhados (`/nova`, `[slug]`)
+
+### Dados → forma
+
+N/A — só navegação.
+
+## Fases verificáveis
+
+1. **Nav** — uma linha em `staffNav` + ícone
+2. **Testes** — unit: href presente para staff, ausente para leader; `isCampaignNavActive` em lista/detalhe/nova
+3. **Gates** — `pnpm gate:fast`; entrega `pnpm push`
+
+## Rabbit holes / Não escopo (engenharia)
+
+- Reordenar demais itens além do encaixe após Lideranças
+- Exportar constante de href (só `MUNICIPALITY_NAV_HREF` tem consumidor especial B18)
+- `staffSecondaryNav` — destino de trabalho, não referência
+
+## Riscos e mitigação
+
+- **Leader vê link:** mitigado — `getCampaignNav('leader')` retorna `leaderNav` separado
+- **Active state em `/nova`:** mitigado — `isCampaignNavActive` usa `pathname.startsWith(\`${href}/\`)`
+
+## Aceite de engenharia

+- [x] Invariantes AGENTS/engineering-standards
+- [x] Testes de domínio previstos (unit) para nav + active state
