+# Impl: Município v2 — shell + faixa de status
+
+Status: aprovado
+Atualizado em: 2026-08-02
+Issue: #330
+Intenção: docs/plans/municipio-v2-shell-status.md
+Appetite restante: ~1–1,5 dia eng (herdado)
+
+## Leitura da intenção
+
+- **Outcome:** rota paralela `/campanha/municipio/<slug>/v2` com faixa de status operável (nível · tendência · sinal · classe · silêncio/frescor · agregado de notas); select abre modal de motivo opcional; confirmação grava; rota antiga intacta; leader lockdown.
+- **O que NÃO negociar:** leader fora; auto-save no select; motivo obrigatório; hero nome/TI no corpo; painel de ajuda inline; padrão distinto para sinal; expor estimado; matar `/municipios/[slug]`.
+- **O que reavaliar:** “nova rota + composição municipality/” (ok); hipótese de só reusar loaders vs extrair view model de status; soft-dep B134 (schema de nível ainda exige motivo + reversalSignals).
+
+## Abordagem recomendada
+
+```mermaid
+flowchart LR
+  Page["municipio/[slug]/v2/page.tsx"]
+  Loader["loadMunicipalityV2StatusData"]
+  Strip["MunicipalityV2StatusStrip"]
+  Modal["MunicipalityV2StatusReasonDialog"]
+  LevelAPI["POST …/engagement-level"]
+  TrendAPI["POST …/political-trend"]
+  SignalFA["createMunicipalityListSignalFormAction"]
+  Page --> Loader --> Strip
+  Strip --> Modal
+  Modal --> LevelAPI
+  Modal --> TrendAPI
+  Modal --> SignalFA
+```
+
+**Opções consideradas:**
+
+|     | A — Thin page + extract shared list controls into strip | B — V2-owned status strip + shared optional-reason dialog; reuse write endpoints | C — Full dual-path ops-sync surface for v2 |
+| --- | ------------------------------------------------------- | -------------------------------------------------------------------------------- | ------------------------------------------ |
+|     | Reusa UI da lista                                       | UI nova densa; writes iguais                                                     | Prematuro (OH cutover)                     |
+
+**Recomendação:** B — because the list cells are Popover/Sheet autosave (trend) or multi-field E14 popover (level), which violate the product rite (select → optional reason modal → confirm). A new strip that calls the same endpoints keeps one write policy without twinning actions.
+
+**Rejeitadas:** A because list UX ≠ select+modal (would force a second mode into list cells or ship the wrong rite). C because B147 is shell-only and appetite forbids dual-path.
+
+### Decisões de engenharia
+
+1. **Rota singular nova** `src/app/(campaign)/campanha/(app)/municipio/[slug]/v2/page.tsx`  
+   Opções: sob `municipios/…/v2` | singular `municipio/…/v2` | query `?v=2`.  
+   **Rec:** singular — matches locked product URL. Rejected: plural (breaks contract); query (pollutes old detail).
+
+2. **Dados da faixa** — thin loader `loadMunicipalityV2StatusData` composing existing detail VM + territorial class + last typed signal preview.  
+   Opções: only `getMunicipalityDetailViewModel` | new loader | dossier loader.  
+   **Rec:** new thin composer over `resolveAccessibleMunicipalityContext` + strategy fields + `computeMunicipalityTerritorialClass` + latest `sinal` update (for type/note aggregate). Rejected: dossier (heavy); detail-only (no last signal type).
+
+3. **Motivo opcional no nível (soft-dep B134)** — relax engagement write schema so empty note OK; stop requiring `reversalSignals` on new writes (omit/empty in snapshot). Align list level control to the same rite (optional note only; drop reversal field from UI).  
+   Opções: leave schema + break “vazio OK” | v2-only bypass with placeholder text | relax schema + update list owner in this PR.  
+   **Rec:** third — product acceptance requires empty OK; edit the owner (schema + list control + action). Historical snapshot scrub / wizard trend step remain on #288 (B134). No Payload migration: `reversalSignals` lives only in `allocationDecision.snapshot` JSON.
+
+4. **Sinal frio (questão aberta da intenção)** — assume A: select value = sentinel “Sem sinal / frio” when cold; age in aggregate/tooltip.  
+   Threshold: `MUNICIPALITY_COLD_SIGNAL_DAYS` (21) from `municipalitySignal.ts` (lista).
+
+5. **Chrome / nome** — no body hero. Path rule → section title `Municípios`; `generateMetadata` uses municipality name. B145 entity-title-in-header stays soft-dep (no twin).
+
+6. **Nível só unrestricted** — strip shows level as readout for advisors; selects for trend/signal for all staff. Gate mirrors list (`canMoveEngagementLevel`).
+
+### Componentes / mudanças
+
+- **`MunicipalityV2Page`** (`src/app/(campaign)/campanha/(app)/municipio/[slug]/v2/page.tsx`): RSC; `requireCampaignPageActor({ gate: 'noLeader' })`; status strip; empty slots for conta/rede/agora (children).
+- **`loadMunicipalityV2StatusData`** (`src/utilities/municipality/municipalityV2StatusData.ts`): server-only composer.
+- **`buildMunicipalityV2StatusAggregate`** (`src/lib/municipalityV2Status.ts`): pure aggregate text + cold sentinel helpers (unit-tested).
+- **`MunicipalityV2StatusStrip`** + **`MunicipalityV2StatusReasonDialog`** (`src/components/campaign/municipality/`): client strip + shared Dialog (motivo opcional).
+- **Schema/action/list level:** `municipalityEngagementLevelSchema` note → optional; `reversalSignals` optional/default `''`; list control drops reversal field; int tests updated.
+- **Chrome:** path rule `/campanha/municipio/[^/]+/v2`.
+- **Form action:** reuse `createMunicipalityListSignalFormAction` (or thin v2 wrapper colocated under the new route).
+- **Migration:** nenhuma.
+- **Access / Consent:** existing municipality access; no Consent; leader blocked by page gate.
+- **UI:** Impeccable C — shape → craft → critique → polish; tokens `data-theme='campaign'`; `CampaignHoverTooltip` + `campaignConceptHref` / `campaignConceptOneLiner`.
+
+### Dados → forma
+
+- Forma: dense control strip (native selects + readouts), not cards/KPIs — qualitative status for CG decisions. Rejected: card tower (old overview); pill cluster for signal (product locked select parity).
+
+## Fases verificáveis
+
+1. **Tracer / server** — schema note optional + reversal optional; loader + pure aggregate; page RSC with strip read-only first; unit tests for aggregate/cold.
+2. **UI** — three selects + modal + writes + tooltips + class/silence; placeholders for children sections.
+3. **Gates** — `pnpm gate:fast`; entrega via `pnpm push`.
+
+## Rabbit holes / Não escopo (engenharia)
+
+- Conta / rede / agora / FAB / cutover (B148–B152).
+- Wizard de tendência (resto B134).
+- Scrub histórico de `reversalSignals` em snapshots.
+- Dual-path / ops-sync.
+- Redesign hysteresis UI beyond override/shock checkboxes already in list (keep minimal in modal when violations apply).
+
+## Riscos e mitigação
+
+- **B134 race:** #288 blocked; we land write-policy subset needed for aceite; comment on #288 that schema/list already optional.
+- **Hysteresis in modal:** keep override + triangulatedShock checkboxes when violations present (same as list), else confirm is one-tap.
+- **Signal body required by schema for non-semanal:** modal “motivo” maps to `body`; empty fails today — relax sinal body to optional in create schema when kind=sinal (motivo opcional), keeping signalType required.
+
+## Aceite de engenharia
+
+- [x] Aceite de produto da intenção ainda coberto
+- [x] Invariantes AGENTS/engineering-standards
+- [x] Testes de domínio: unit aggregate/cold; int engagement level empty note; list control still submits
+
+Self-score decision-quality: 4/5
