Backend: - Chat, Message, ContextFile models + Alembic migration - Chat CRUD with per-user limit enforcement (max_chats) - SSE streaming endpoint: saves user message, streams Claude response, saves assistant message with token usage metadata - Context assembly: primary context file + conversation history - Admin context CRUD (GET/PUT with version tracking) - Anthropic SDK integration with async streaming - Chat ownership isolation (users can't access each other's chats) Frontend: - Chat page with sidebar chat list + main chat window - Real-time SSE streaming via fetch + ReadableStream - Message bubbles with Markdown rendering (react-markdown) - Auto-growing message input (Enter to send, Shift+Enter newline) - Zustand chat store for streaming state management - Admin primary context editor with unsaved changes warning - Updated routing: /chat, /chat/:chatId, /admin/context - Enabled Chat and Admin sidebar navigation - English + Russian translations for all new UI Infrastructure: - nginx: disabled proxy buffering for SSE support - Added ANTHROPIC_API_KEY and CLAUDE_MODEL to config Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
