+Significance: patch
+Type: fixed
+
+Search Dashboard: guard `<PlanInfo>` and `<PlanUsageSection>` against missing wpcom plan fields so the dashboard React tree no longer throws "Cannot read properties of undefined" when `state.sitePlan.plan_usage` or `plan_current` is partially populated. Three landmines: `getLatestMonthRequests` selector's unguarded `[ 0 ]` after the `?.`; `displayPeriodFromAPIData` accessing `latestMonthRequests.start_date` without nullish guard; and the missing `?.` on `currentPlan.monthly_search_request_limit` in `usageInfoFromAPIData`. The dashboard now renders cleanly even when the wpcom plan response hasn't fully resolved.
