- Writing assistant: inject project notes as context (definition-tagged first), wikilink suggestions - Link suggestions: server-side endpoint finds unlinked term occurrences, NoteEditorView sidebar panel - Project-scoped RAG: ChatView ProjectSelector filters semantic+keyword search to selected project - Semantic search tool: LLM search_notes upgraded to hybrid semantic (0.40 threshold) + keyword merge - SSE race condition fix: drain remaining events after stream loop exits in chat.py and notes.py - RAG_AUTO_SNIPPET raised 800→4000; sidebar include uses full note body; MAX_BODY_CHARS 8000→24000 - Enter-to-submit on writing assistant instruction textareas (note and task editors) - DiffView: equal-line collapsing with 3-line context around changes Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
