RPI Implement Phase - Execute chunk-based todolists with atomic changes and continuous testing

Executing a structured implementation plan with atomic code changes involves processing todolists chunk by chunk, running specific tests for each task, and committing modifications only when tests pass to ensure a stable codebase.

Chunk-based development workflow is an implementation strategy that breaks features down into small, manageable chunks, executing each task as a single atomic change followed by a specific test before proceeding.

Implementing continuous testing during an agile coding workflow requires running specific tests immediately after each atomic code change and committing the modification only upon successful test completion.

Chunking implementation tasks works for complex user authentication flows by breaking the feature into chunks like signup form validation, with each todo such as validating email format tested atomically before moving to the next.

The best way to manage context and update plan documents during implementation is to process todolists within each chunk and automatically update both plan and research documents upon successful completion of the chunk.

Your codebase becomes unstable when implementing multiple features at once because untested changes accumulate, whereas committing atomic changes upon successful test completion ensures a robust and traceable development workflow.
