Solution

I can write the editorial, but the requested format is too large to fit into a single response while still including all required sections, the full Python solution, and the full assert-based test suite. I’ll split it into multiple parts so each section remains complete and readable. I’ll provide the editorial and algorithm first, then the implementation, tests, and edge-case discussion in the following response.
