refactorlisted

# Refactor - Establish the behavior and contracts that must remain unchanged before restructuring. - Improve a named problem in ownership, coupling, state, types, boundaries, or comprehension without inventing product behavior. - Update affected consumers and remove superseded affected paths so one implementation remains. - Compare the relevant real behavior before and after, then run applicable repository gates. Read `agent-rules/reference/principles.md`, `agent-rules/reference/boundaries.md`, `agent-rules/reference/types-and-state.md`, or `agent-rules/reference/testing.md` when applicable. Finish when preservation evidence is usable, callers and artifacts agree, and the change reduces the stated problem without unrelated redesign.
