The non-streaming Anthropic path leaked OpenAI chat.completion bodies to Claude clients when the upstream provider forces streaming (forced SSE->JSON path): parseSSEToOpenAIResponse yields choices[] which Claude Code cannot parse. Convert to Claude Messages shape for sourceFormat CLAUDE in sseToJsonHandler. Shared toClaudeMessageShape/openAICompletionToClaudeMessage moved to translator/concerns/claudeShape.js to avoid circular import between nonStreamingHandler and sseToJsonHandler. 5 new tests: sse-to-json reassembly + Claude guard, plus existing anthropic-nonstream-shape updated to import from the concern.
