## Currently Active Bugs

### P2 - 7B Model Produces Garbage Streaming Output

**File:** `docs/bugs/P2_7B_MODEL_GARBAGE_OUTPUT.md`
**Status:** OPEN - Investigating

**Problem:** When running Free Tier (Qwen2.5-7B-Instruct), the streaming output shows garbage tokens like "yarg", "PostalCodes", "FunctionFlags" instead of coherent agent reasoning.

**Root Cause:** The 7B model has insufficient reasoning capacity for the complex multi-agent framework prompts.

**Potential Fixes:**
1. Switch to a better small model (Mistral-7B, Phi-3, Gemma-2-9B, Qwen2.5-14B)
2. Simplify Free Tier architecture to single-agent mode
3. Add output filtering/validation
4. Prompt engineering specifically for 7B models

### P3 - Progress Bar Positioning in ChatInterface

**File:** `docs/bugs/P3_PROGRESS_BAR_POSITIONING.md`
**Status:** OPEN - Low Priority UX Polish

**Problem:** The `gr.Progress()` bar renders in a strange position when used inside ChatInterface, causing visual overlap with chat messages.

**Recommended Fix:** Remove `gr.Progress()` entirely and rely on emoji status messages in chat output.

## Tech Debt (Future Roadmap)

### P3 - Remove Anthropic Partial Wiring

**File:** `docs/future-roadmap/P3_REMOVE_ANTHROPIC_PARTIAL_WIRING.md`
**Status:** OPEN - Tech Debt

**Problem:** Anthropic is partially wired but NOT fully supported (no embeddings API). Creates confusion.

**Fix:** Remove all Anthropic references from codebase. See doc for file list.
