📄 Description

Problem

Production failures in Ollama LLM provider with error:

UnboundLocalError: cannot access local variable 're' where it is not associated with a value

Impact: 66 failures in single session (Nov 29, 2025)

Root Cause

OllamaProvider.generate_structured() had redundant import re on line 416 inside an except block.

Python treats imports as assignments, making re a local variable for the entire function scope. When lines 350-402 tried to use re before line 416 executed, Python raised UnboundLocalError.

Code structure:

def generate_structured(...):
    try:
        content = re.sub(...)     # Line 350 - tries to use 're'
        json_match = re.search()  # Line 362 - tries to use 're'
        content = re.sub(...)     # Lines 401-402 - tries to use 're'
    except json.JSONDecodeError:
        import re                 # Line 416 - makes 're' local for ENTIRE function
        code_match = re.search()  # Line 419 - uses local 're'

Solution

Remove line 416. Module-level import re (line 9) is sufficient for all uses.

Verification

✅ Python AST analysis confirms scoping bug
✅ 11 uses of re in method all work with module-level import
✅ No other similar issues in codebase
✅ Zero functionality lost

Files Changed

packages/llm_analysis/llm/providers.py (-1 line)

Testing

Verified by:

Python AST scope analysis
Production error logs analysis
Manual code inspection

Risk: None - removes redundant code only

Note

Remove redundant local import re in OllamaProvider.generate_structured to prevent UnboundLocalError during JSON parsing.
