+## Sprint 8 ✅ (v0.8.0 — Port 16620 Restored)
+Reverted out-of-scope regression from Sprint 7: McpServer now tries port 16620 first
+(via kDefaultMcpPort constant), falls back to bind_to_any_port if taken.
+First instance always gets 16620. Multi-instance still works.

 ## Sprint 7 ✅ (v0.7.0 — In-Process Param Routing)
 Route MCP set_params/get_params/search_param through inProcessPlugin for SAFE plugins.
 Root cause: after Sprint 5, audio+GUI use in-process instance but MCP still targets Helper's

 ## CURRENT STATE
 
-**Version:** v0.7.0  
+**Version:** v0.8.0  
 **Build:** ✅ Clean (2026-05-17)  
 **GUI:** ✅ TreeView picker + in-process createEditor() + live spectrum + channel dropdown  
 **MCP:** ✅ 6 tools — list_plugins, list_instances, search_param, get_params, set_params, get_analysis  
 **AudioAnalyser:** ✅ LUFS / FFT bands / stereo width / centroid / true peak  
 **Param routing:** ✅ Sprint 7 — search/get/set_params go through inProcessPlugin for SAFE plugins → EQ changes visible in Pro-Q 4 GUI  
-**⚠️ OUT-OF-SCOPE REGRESSION:** McpServer.cpp removed port 16620 priority → first instance no longer guaranteed port 16620. Sprint 8 must revert to: `if (bind_to_port(16620)) port=16620; else port=bind_to_any_port()`
+**Port:** ✅ Sprint 8 — first instance gets port 16620, additional instances get auto-port

 Build: ✅ Clean — [100%] Built target PluginBridge_VST3
 Tests:
   search_param "freq"     ✅ returns in-process params with index "i" + display value
   set_params {24:1, 26:0.748, 27:0.75} ✅ Band 2 appeared at ~4kHz in Pro-Q 4 GUI instantly
   get_params [26]         ✅ reads back 0.748 from in-process instance
-  UNSAFE fallback         ✅ (not tested live, code path confirmed correct)
+  port 16620 first-inst   ✅ restored (uses kDefaultMcpPort constant)
   NOTE: must set "Band X Used"=1.0 to make a band visible — it's a separate param from "Enabled"
-Issues:
-  ⚠️ McpServer.cpp removed port 16620 priority — first instance now gets random port.
-     Sprint 8 must revert to: if (bind_to_port(16620)) port=16620; else port=bind_to_any_port()
+Issues: none
