Implement classes within an abstract Python framework

You are given an existing Python codebase (~200 lines shown) that defines an abstract base class DataProcessor with abstract methods load(self), transform(self, record), and save(self, records); a registry/factory that instantiates processors by name; and a CLI that wires them together. Without editing the abstractions, implement a concrete CsvToJsonProcessor that: ( 1) reads CSV files in chunks; ( 2) transforms each row to a normalized JSON object; ( 3) writes line-delimited JSON to an output path; ( 4) handles bad rows with a retry/logging policy; and ( 5) integrates with the registry so the CLI can invoke it by the name 'csv_to_json'. Provide the class implementation outline and explain the control flow through the existing template methods.
