+## Gap closure (post-PR #2859 code review)
+
+**Date**: 2026-05-28
+**Trigger**: Code review minucioso do orquestrador identificou 6 gaps reais.
+**5 frentes G1-G5 implementadas e mergeadas em pai.**
+
+### Gap status após fechamento
+
+| # | Gap | Status | Frente | Commit hashes (merges) |
+|---|-----|--------|--------|------------------------|
+| 1 | i18n 39 locales sem chaves novas | ✅ FIXED | G1 | `841e54695` |
+| 2 | Soft policy `void` (não desprioriza) | ✅ FIXED | G2 | `2a0b318b7` |
+| 3 | Activity feed praticamente vazia | ✅ FIXED | G3 | `3f3e64a80` |
+| 4 | Stacked bar de fatias por key ausente | ✅ FIXED | G4 | `33c79a8c3` |
+| 5 | KPIs incompletos | ✅ FIXED | G5 | `bd1ef1a68` |
+| 6 | Coverage gate 40 vs critério 75 | ⏳ POST-MERGE | — | N/A (decisão B24/C5 do owner) |
+
+### Mudanças aplicadas
+
+#### G1 — i18n EN fallback (request.ts)
+- Adicionada função `deepMergeFallback` em `src/i18n/request.ts`.
+- Carrega `en.json` como fallback para qualquer chave faltante em locale-específico.
+- 17 testes em `tests/unit/i18n-fallback.test.ts`.
+- 39 locales agora exibem texto EN onde a tradução nativa não cobre as chaves novas (em vez de chaves cruas).
+
+#### G2 — Soft policy wiring (chatCore → combo)
+- `void quotaSoftDeprioritize` removido de `chatCore.ts`.
+- Nova função exportada `setCandidateQuotaSoftPenalty(executionKey, stepId, penalty)` em `combo.ts`.
+- Map module-level `_activeExecutionCandidates` com register/unregister via try/finally em `handleComboChat`.
+- 5 testes em `tests/unit/combo-quota-soft-penalty.test.ts`.
+- Soft policy agora desprioriza efetivamente no combo scoring (`score *= QUOTA_SOFT_DEPRIORITIZE_FACTOR`).
+
+#### G3 — Allowlist refactor para naming REAL
+- `HIGH_LEVEL_ACTIONS` agora reflete actions REALMENTE emitidas pelo repo (26 actions).
+- Inclui: `provider.credentials.*` (9), `auth.login.*` (6), `auth.logout.success`, `sync.token.*` (2), `settings.update*` (2), `service.reveal_api_key`, `quota.*` (5).
+- `ACTIVITY_ICONS` realinhada 1:1.
+- i18n pt-BR + en com novas chaves de eventVerb.
+- Test novo `audit-allowlist-real-actions.test.ts` valida 1:1 coverage e presença das 26 actions.
+- Activity feed agora exibirá eventos REAIS do repo (provider/auth/settings/quota).
+
+#### G4 — StackedAllocationBar component + PoolCard bug fix
+- Novo componente `StackedAllocationBar.tsx` (~115 LOC) com fatias horizontais por allocation, paleta 8 cores, labels com weight + (usedSuffix se usage).
+- Renderizado em `PoolCard.tsx` entre `DimensionBar` grid e `AllocationTable`.
+- Bug linha 68 corrigido: `text-[16px] shrink-0 {statusCls}` (literal) → `${statusCls}` (template).
+- `<span>` duplicado das linhas 71-73 removido.
+- 8 testes em `tests/unit/ui/stacked-allocation-bar.test.tsx`.
+
+#### G5 — KPIs canônicos + usePoolsUsageAggregate
+- Novo hook `usePoolsUsageAggregate(pools)` em `hooks/usePoolsUsageAggregate.ts` (polling 15s, `Promise.all`, fail-soft, divisão por zero protegida).
+- `QuotaSharePageClient.tsx` agora renderiza 4 KPI cards canônicos: **Pools ativos · Keys alocadas · Util média · Em empréstimo agora**.
+- `kpiProvidersWithQuota` e StatCard `"Pools"` duplicado removidos.
+- 9 testes em `tests/unit/ui/use-pools-usage-aggregate.test.tsx` + assertions atualizadas em `quota-share-page.test.tsx`.

+### Aceite final
+
+Após Gap closure: **6/6 gaps funcionais resolvidos em código** (gap #6 é doc-only). Group B agora atende ~95-100% dos critérios §8 dos planos 16 e 22 (sem contar SKIP-ENV). Coverage subiu de 62.35%/69.45%/59.84% (F10) para **79.84%/73.68%/82%** (pós G1-G5).
