+### 2.9 — `accent` no enum V2 (severity: error quando declarado, warn quando ausente)
+
+O shell aceita 7 valores fechados pro `accent`. Se declarado fora desse set, o `POST /api/modules` rejeita. Se ausente, o shell auto-infere via hash deterministico do `id` — sem custo, mas vale informar pro dev:
+
+```bash
+ACCENT=$(jq -r '.accent // ""' module.json)
+case "$ACCENT" in
+  "")
+    PROBLEMS+=("aviso: accent ausente — shell vai auto-inferir do hash do id (estavel, mas sem identidade declarada)")
+    ;;
+  coral|amber|violet|teal|blue|rose|lime)
+    : # ok
+    ;;
+  *)
+    PROBLEMS+=("erro: accent \"$ACCENT\" fora do enum (use coral|amber|violet|teal|blue|rose|lime)")
+    ;;
+esac
+```
+
+### 2.10 — `icon` ausente (severity: warn)
+
+`icon` e nome lucide em kebab-case. Sem ele, o shell usa o default do `group`. Se ambos `accent` e `icon` ausentes, modulos do mesmo grupo ficam visualmente indistinguiveis na grid:
+
+```bash
+ICON=$(jq -r '.icon // ""' module.json)
+if [ -z "$ICON" ]; then
+  PROBLEMS+=("aviso: icon ausente — chip vai usar default do group \"$GROUP\"")
+fi
+```
+
+### 2.11 — Hardcoded colors no `src/` (severity: warn)
+
+Modulos devem consumir CSS custom properties (`var(--token)`) em vez de fixar hex. Cores fixas escapam quando o shell troca de tema (light/dark) ou quando o palette V2 evolui.
+
+O grep filtra falsos positivos comuns: comentarios (`//`, `*`, `/*`), declaracoes de CSS var (linhas que comecam com `--token:`), e qualquer linha que ja referencia `var(--`. O total de ocorrencias e contado **antes** do truncate, e ate 5 amostras vao no report pra dar contexto:
+
+```bash
+HARDCODED=$(grep -rnE "#[0-9a-fA-F]{3,8}\b|rgb\(|rgba\(" src/ \
+    --include='*.ts' --include='*.tsx' --include='*.css' 2>/dev/null \
+  | grep -v "var(--" \
+  | grep -vE "^[^:]+:\s*//|^[^:]+:\s*\*|^[^:]+:\s*/\*" \
+  | grep -vE "^[^:]+:\s*--[a-zA-Z0-9_-]+:")
+
+if [ -n "$HARDCODED" ]; then
+  TOTAL=$(echo "$HARDCODED" | wc -l)
+  PROBLEMS+=("aviso: $TOTAL cor(es) hardcoded em src/ — use var(--token) para respeitar light/dark e o palette V2")
+  while IFS= read -r line; do
+    PROBLEMS+=("  $line")
+  done <<< "$(echo "$HARDCODED" | head -5)"
+fi
+```
+
+> `grep -n` traz numero da linha pra cada amostra ficar acionavel. Falsos positivos ainda sao possiveis (rgba em sombras decorativas, hex em SVG icons inline) — por isso e aviso, nao erro.

+## Identidade visual — accent e icon
+
+Cada módulo aparece no grid da Home do shell como um **card** com um chip colorido (44×44) e um ícone. Dois campos opcionais no `module.json` controlam isso:
+
+```json
+"accent": "coral",
+"icon": "shield",
+```
+
+**accent** — cor do chip. Um destes 7 valores:
+
+| accent | hue (aprox.) | uso típico |
+|---|---|---|
+| `coral`  | vermelho coral | ações principais / regulatório |
+| `amber`  | âmbar          | configuração / toggles |
+| `violet` | roxo           | orquestração / fluxo |
+| `teal`   | verde-azul     | aprendizagem / coleta |
+| `blue`   | azul           | ferramentas / API |
+| `rose`   | rosa           | suporte / pessoas |
+| `lime`   | verde-lima     | dados / analytics |
+
+**icon** — nome do ícone [lucide](https://lucide.dev/icons/) em kebab-case (ex.: `shield`, `git-branch`, `database`, `book-open`, `key`).
+
+### Os dois são opcionais
+
+Se você não declarar **accent**, o shell pega 1 dos 7 valores via hash determinístico do `id` do módulo — mesmo `id` sempre cai na mesma cor, em qualquer sessão e dispositivo.
+
+Se você não declarar **icon**, o shell usa um default por `group`:
+
+| group | icon default |
+|---|---|
+| `operations`       | `layers` |
+| `finance`          | `wallet` |
+| `customer-support` | `life-buoy` |
+| `analytics`        | `chart-line` |
+| `settings`         | `settings` |
+
+> Sem custo cognitivo no dia 1 — declare quando quiser dar identidade visual ao módulo, deixe vazio quando estiver tudo bem com o auto.
+
+A skill `/check-module` valida se o `accent` declarado está no enum e avisa quando os dois estão ausentes (informativo — não bloqueia deploy).

 ## Sidebar — Navegação e Perspectivas
 
 Por padrão o `module.json` declara um **menu único** no campo `navigation` (caso da maioria dos módulos):
