Changelog

v2.0.0 (2026-06-03) — Odysseus UI + Multi-Provider + RAG

Added

• Complete Odysseus-style UI with Tokyo Night color palette
• Multi-provider LLM support (OpenAI, Anthropic, Ollama, OpenRouter, Groq, custom)
• RAG pipeline: dual-source context from Wiki KB (:8097) + VectorDB (:8099)
• Per-session RAG toggles (Wiki KB / VectorDB enable/disable)
• Chat modes: Chat, Code, Brainstorm with mode-specific system prompts
• Session history with localStorage persistence (up to 50 sessions)
• Save AI answers as new Q&A entries to Wiki KB
• Message action buttons: Copy, Redo, Save-to-Wiki on AI responses
• Markdown rendering in AI replies (bold, italic, code blocks, lists)
• Provider management: CRUD for custom providers, preset forking with API keys
• SSE streaming with format detection (OpenAI vs Anthropic)
• Model picker dropdown in input bar
• Manage Providers modal with select/edit/delete
• Quick action chips on welcome screen
• Mobile responsive layout with sidebar drawer

Backend (wiki-vector-chat.py)

• FastAPI service on port 8770
• Shared API token auth from /opt/blog/.wiki-api-token
• build_rag_context() with per-source toggle support
• call_llm_stream() with format auto-detection
• Anthropic SSE parsing (content_block_delta, message_stop)
• POST /chat/save-to-wiki writes directly to wiki-kb.json
• ChatMessage model extended with rag_wiki, rag_vector, mode fields

Fixed

• VectorDB search read wrong field (text vs content) - all results were empty strings
• VectorDB author/channel are top-level, not nested under metadata
• Missing API key showed cryptic HTTP 401 instead of helpful guidance
• Added friendly error messages for HTTP 429/403 during streaming

Fixed (earlier)

• "Save failed: fetch().json is not a function" — double await
• RAG chevron toggle checked CSS class instead of state
• addMessage wrong arguments (empty objects vs string roles)
• SSE done not breaking outer loop — streamDone flag
• Welcome screen never hidden — .hidden CSS class + toggle
• Preset providers not editable — forking with custom- prefix
• RAG not working — auth tokens for wiki-api and vector-db
• Anthropic message format — {role, content} not {type, text}
• Anthropic SSE parsing missing — added content_block_delta handler
• LLM ignoring RAG context — improved system prompt instructions
• Markdown showing raw tags in AI replies — renderMd() conversion

v1.0.0 (2026-05-28) — Initial

• Basic chat UI embedded in wiki
• Single-provider Z.ai GLM-4 proxy (wiki-chat-server.js on :8098)
• Wiki KB search integration
