# Code Simplification & Refactoring Plan

## Refactoring Scope
- **Target File**: `src/services/data-processor.ts`
- **Target Function**: `processBatchRecords()`
- **Current Cyclomatic Complexity**: 18
- **Target Cyclomatic Complexity**: <= 6

## Planned Transformations
1. Invert nested conditionals into top-level guard clauses.
2. Extract low-level record validation into `validateRecordPayload()`.
3. Replace manual for-loops with clear typed functional transformations.

## Verification Gate
- [x] All existing unit tests pass before refactoring (`bun test test/data-processor.test.ts`).
- [x] Zero changes to public export signatures or return types.
- [x] All unit tests pass after refactoring.
