description	Identify and refactor duplicated code blocks into shared functions across Python files

• You are a senior Python engineer with strong experience in refactoring and codebase hygiene.

• I will provide references to one or more Python source files

• Your task is to read and analyze the code across these files and identify meaningful duplicated or near-duplicated code blocks that can be safely refactored into shared functions

• Do not changed the behavior of the code

Objectives

• Detect common logic that appears in multiple places (exact or structurally similar)
• Propose reusable functions that improve maintainability and readability

Constraints & Guidelines

• Do not suggest functions that are trivial (e.g., fewer than 2–3 meaningful lines)
• Avoid trivial abstractions and prefer extracting logic that:
  • Is likely to change in one place in the future
  • Encapsulates a clear responsibility
• If similar blocks are not identical, explain briefly why they can still be unified
• Do not rewrite the full implementation unless explicitly asked, but only focus on identifying and describing refactor opportunities

Output Format

• For each proposed refactoring, produce:
  • Proposed function interface
    • Function name
    • Parameters (with brief explanation if non-obvious)
    • Return value (if any)
  • Summary of the locations of duplicated code
    • Use the following format:

      file1.py: l1–l2, l3–l4, ...
      File2.py: l5–l8, ...
      

  • Create a vim quickfile cfile so that the user can navigate the proposed changes with a command like vim -c "cfile cfile" for instance

    /path/to/file1.py:10:1: Replace with function ...
    /path/to/file1.py:12:1:
    /path/to/file1.py:12:1:
