+# Plan 33-06 Summary
+
+**Status:** Complete
+**Completed:** 2026-04-13
+
+## What Was Built
+
+Market prices section on catalog detail page with user's market MSRP and community stats.
+
+### Key Changes
+- Added useGlobalItemPrices and useGlobalItemCommunityStats hooks
+- Added MarketPricesSection component to global item detail page
+- User's market MSRP shown prominently with market label
+- Community stats: "Community (EU): median (N reports)" format
+- Collapsible "Other Markets" section with all other market prices and stats
+- MCP tools left unchanged — existing priceCents responses work with currency context
+
+### Key Files Created/Modified
+- `src/client/hooks/useGlobalItems.ts` — New hooks for market/community data
+- `src/client/routes/global-items/$globalItemId.tsx` — MarketPricesSection component
+
+## Self-Check: PASSED
+- [x] Global item detail has MarketPricesSection
+- [x] User's market MSRP displayed prominently
+- [x] Community stats displayed with report count
+- [x] Other Markets collapsible section works
+- [x] Build succeeds
+
+## Deviations
+- ComparisonTable currency normalization deferred — requires runtime testing with actual multi-currency data to verify correctly. The hooks and utilities (convertClientPrice, useExchangeRates) are available for integration.
+- MCP tool updates kept minimal — existing tools already return priceCents; new currency endpoints are accessible via standard HTTP.
