⬆️ Upgrade Log: Gemini 2.0 Migration

Date: 2025-12-07 Version: CrumbCore v1.1 (Gemini Edition)

🚀 Changes

1. Model Migration

All roles in the Crumbforest have been migrated from OpenAI (GPT) and Anthropic (Claude) to Google Gemini 2.0.

• Old: openai/gpt-4o-mini, anthropic/claude-3-5-sonnet
• New: google/gemini-2.0-flash-001
• Reason: Unified "Gemini Context", improved performance, lower latency, and simplification of provider usage via OpenRouter.

2. Configuration

The crumbforest_config.json has been updated to reflect these changes.

• The system remains flexible: Individual roles can be switched back to other models anytime by editing the model field in the config.
• No new API keys required (uses existing OpenRouter key).

3. Stability & RAG

• Fixed "Internal Server Error (RAG)" by ensuring correct model IDs.
• Verified vector search against Qdrant collections (docs_crumbforest_, docs_rz_nullfeld_).
• All 15 roles successfully retrieve context and answer in character.

4. Admin Enhancements

• Vector Admin Dashboard now includes correct Gitea linking logic.
• Admin Logs correctly track model usage.
