 # Escala e DRY pós-B13 (escala relativa no mapa dos Municípios)

-Status: rascunho
-Atualizado em: 2026-07-26
+Status: entregue (2026-07-29)
+Atualizado em: 2026-07-29
 Item do roadmap: [docs/roadmap.md](../roadmap.md) (Fill-ins abertos, **B13+**, fill-in de engenharia)
 Impeccable: A — N/A (nenhuma superfície nova; as quatro fases preservam o comportamento visível do B13, exceto uma linha de copy em F2)
 Appetite: ~0,5–0,75 dia eng; quatro fases independentes, nenhuma com migration, collection ou `Consent`

 - ~~**B8+** escala/DRY pós-B8 F2~~ — **✓ (entregue 2026-07-27)** as quatro fases do `/simplify` dos polígonos das ZE. **F1:** a política de escala de chão nasceu em `scripts/lib/topology.mjs` (primeiro módulo de `scripts/lib/` — **B5 F2** pousa nele) declarando tolerância de Visvalingam em **m² de chão** e derivando os dígitos de quantização do bbox de cada topologia; `SIMPLIFY_QUANTILE`/`QUANTIZE_DIGITS` morreram nos dois scripts. A auditoria corrigiu a alavanca do plano: quantização sozinha quase não corta (mesmo na grade estadual as zonas ficariam em 203 pontos/feature), o peso absoluto é que manda — as zonas caíram de **9.120 → 574 pontos de arco (480 → 30,2/feature) e 72.310 → 7.687 bytes**, `bahia-municipalities` saiu **byte-idêntico** e territórios mudou 1 byte (grade 102,730 → 102,822 m). Tolerância própria por malha, com o número medido no comentário: a tolerância municipal chegaria a 17,9/feature nas zonas mas comeria 5% da área de Salvador (306 → 291 km²), que é justamente a grandeza que prova que nenhum bairro sumiu. `MAX_TOPO_BYTES` ganhou ao lado `MAX_POINTS_PER_FEATURE = 60`. **F2:** `featureMapKey` passou a ser exercido sobre features **reais** das três malhas, cada uma no laço que já a varre inteira (417 `codarea` + 27 `code` + 19 `slug`) — o `/simplify` corrigiu a primeira escrita, que asseria a cidade dentro do laço das zonas e portanto cobria **uma** feature municipal 19 vezes; o teste de precedência sintético caiu e o comentário passou a declarar o invariante real (as três propriedades de chave são mutuamente exclusivas; `ibgeCode` na zona deliberadamente não é chave). **F3:** `.catch()` na metade das zonas — o mapa segue sem elas (com o motivo logado), com Salvador como polígono sem dado nem interação — e a ressalva de aproximação saiu do gate `!comparisonActive` para um `<p>` condicionado a `bundle.hasZoneMunicipalities`, campo novo publicado pelo loader a partir de `kind === 'zona'`: o `/simplify` **rejeitou** o predicado `isZoneMapKey` que lia isso da forma da chave (7 dígitos ⇒ município), porque era uma segunda codificação da regra de `mapKeyForMunicipality`, e gatear em `zoneBreakdown` recriaria o acoplamento que o fill-in da lista (✓ 2026-07-28) deletou. **F4:** dois acessores órfãos deletados, a união de navegação de 3 estados colapsada em `string | undefined`, `MunicipalitiesByMapKey` virou `Record<string, string>` (435 strings fora do payload RSC do Início), `polygonRingsOf` exportado e os helpers de geometria retipados em `PolygonalFeature`/`BahiaFeature<P>`/`BahiaMeshFeature`. **Um item do plano foi rejeitado por medição:** `city`/`zoneNumber` de `MunicipalityZoneNeighborhoodEntry` **ficam** — entram nas linhas hasheadas por `canonicalEvidenceRows` e são colunas do fixture de proveniência da RA 02/2017, então não são código morto (só o `zoneNumber` do **artefato** TopoJSON saiu) · sem migration · [plano](plans/escala-dry-pos-b8f2.md)
