Architecture fix: voice and text mode now have completely separate prompts.
Backend:
- VoiceAssistantProfileSupport.buildTextSystemRole: dedicated text-mode system
role that inherits all business rules (identity, KB-first, sensitive topics,
sales guidance, personal info) but removes voice-specific constraints (short
sentences, colloquial, single-line conclusion).
- DEFAULT_TEXT_SPEAKING_STYLE: text-specific style demanding detailed,
structured, Markdown-formatted answers with complete information.
- VoiceGatewayService.handleStart: switch between voice/text system role and
speaking style based on state.textMode.
- VoiceGatewayService.buildStartSessionPayload: preserve Markdown in text mode
(voice mode still strips asterisks/backticks via normalizeTextForSpeech to
avoid TTS pronouncing format chars).
Frontend:
- Added react-markdown@9 + remark-gfm@4 dependencies.
- ChatPanel renders assistant messages (non-voice) with ReactMarkdown:
headings, lists (ul/ol), bold, italic, inline/block code, tables, blockquote,
links, horizontal rules — all styled with Tailwind classes matching the dark
theme.
- User messages and voice-handoff messages remain plain text.
Verification: mvn test VoiceGatewaySmokeTest 20/20 pass, vite build succeeds.
