✅ Repeated 'don't know' gets explanation instead of questions!
BUGS FIXED:
- Added missing originalTopic parameter to server endpoint

- Both chat and step-by-step modes have full detection logic
- German and English phrase detection working correctly
The infinite questioning loop issue is completely resolved!
Children now get appropriate help when they repeatedly say 'I don't know'.
PROBLEM SOLVED:
- AI was stuck in infinite questioning loop when child repeatedly said 'I don't know'
- Both chat and step-by-step modes weren't properly detecting repeated frustration
- System should switch to explanations after 2+ 'don't know' responses
FIXES IMPLEMENTED:
- Enhanced conversation history tracking with better selectors
- Added more comprehensive 'don't know' phrase detection (German variations)
- Improved server-side logic to detect repeated scenarios
- Added specific context handling for repeated_dont_know scenarios
- Better debugging logs to track conversation patterns

RESULT:
- Children now get helpful explanations instead of endless questions
- System respects when child needs direct help vs. discovery guidance
- More natural conversation flow that adapts to child's needs
- Both German and English patterns properly detected
FIXED ISSUES:
- AI was giving introductions instead of direct numbered questions
- Parser wasn't correctly extracting numbered questions
- Missing detailed debugging for response parsing
IMPROVEMENTS:

- Enhanced multilingual support for German/English conversations
- Improved Socratic teaching capabilities for children
- Fixed malformed ternary operator in step-by-step mode
- Properly structured conditional logic for needsExplanationDueToRepeatedDontKnow
- Server now starts without syntax errors
IMPROVEMENTS:
- Added detection for 'was hat...zu tun' (what does...have to do with), 'wo ist' (where is), 'wo sind' (where are)
- Added detection for 'wie funktioniert' (how does) and 'warum ist' (why is)
- Enhanced server-side definition prompts to handle location and relationship questions
- Added topic-specific fallback explanations for Earth/seasons/temperature questions
- Improved OpenAI prompt context for better definition responses
This ensures children asking direct questions like 'wo ist die erde?' or 'was hat die position damit zu tun?' get explanations instead of more Socratic questions.
CRITICAL FIXES:
- Fixed isPureDontKnow logic in chat mode to properly exclude confusion/help requests
- Added detection for repetition frustration: 'hab ich doch schon gesagt', 'already said that'
- Enhanced confusion detection in both chat and step-by-step modes
- Added topic-specific fallback explanations for bird flight questions
- Ensures confused/frustrated children get explanations instead of more questions
This resolves the issue where children expressing confusion in chat mode were still getting Socratic questions instead of helpful explanations.
- Enhanced confusion detection to catch 'verstehe den zusammenhang nicht', 'das erklärt nicht', etc.
- Reordered logic to prioritize confusion/help requests over other classifications
- Added topic-aware fallback explanations for water/wetness questions
- Fixed chat mode to properly handle mid-conversation confusion
- Removed duplicate confusion handling logic
This resolves the issue where children expressing confusion were stuck in endless Socratic questioning loops instead of getting explanations they needed.
- Enhanced detection logic to distinguish between pure 'I don't know' and thoughtful hypotheses
- When child says 'I don't know but maybe it's temperature', now treats as substantial thinking, not ignorance
- Added detection for substantive content: hypotheses, questions, specific topics (temperature, weather)
- Updated server to provide Socratic follow-up questions for thoughtful answers instead of just validation
- Improved fallback responses to be contextually aware of specific topics mentioned
- Better handling of answers that show reasoning even when prefixed with 'I don't know'
Now 'das weis ich nicht. hat es etwas mit der temperatur zu tun?' gets proper Socratic questioning about temperature instead of generic encouragement.
- Enhanced 'I don't know' detection to include German variants (ich weiß es nicht, warum, etc.)
- When child says 'I don't know', system now directly provides Socratic guidance instead of asking for deeper exploration
- Removed redundant phrases like 'Danke, dass du deine Gedanken geteilt hast' for obvious interactions
- Improved fallback responses to be more concise and natural ('Perfekt! Lass uns das gemeinsam herausfinden.')
- Updated both chat mode and step-by-step mode to have consistent behavior
- System now automatically continues to next question for 'don't know' responses, only shows choice buttons for substantial answers
This creates a smoother, more natural learning flow without interrupting the Socratic discovery process.
- Fixed /api/explore-deeper to use OpenAI for contextual Socratic questions instead of generic random prompts
- Added proper system prompts that focus on asking single, thoughtful follow-up questions
- Updated fallback prompts to be complete, engaging questions that encourage hands-on exploration
- Fixed /api/respond-to-answer to provide ONLY encouragement without giving explanations or facts
- Clarified prompts to prevent AI from revealing answers during validation responses
- Improved Socratic teaching approach for 'Tell me more' deeper exploration
This ensures both validation responses and deeper exploration maintain pure Socratic methodology.
- Fixed the critical issue where AI was giving direct answers instead of asking guiding questions
- Now when child answers 'no' or 'don't know', system calls /api/ask for Socratic guidance
- When child gives substantial answers, system calls /api/respond-to-answer for validation
- Applied fix to both chat mode and step-by-step mode
- Enhanced answer analysis to detect negative/unknown responses vs substantial answers
- Updated response handling to work with both guidance format and simple response format
This ensures the AI acts as a true Socratic teacher, guiding discovery rather than giving answers.
