 This artifact turns the parity matrix plus live official catalog snapshot into
 an execution-friendly view:
 
-- what should go through official MCP
+- what should go through the official REST Calculate bridge (default)
 - what should go through the official Python bridge
-- what should go through the REST adapter
 - what should stay local because the repo is already stronger there
+- official MCP remains protocol-probe only after tools/call regression
