Documentation checklist

For every new or modified public symbol in nvsubquadratic/ or experiments/:

• Every new module has a module-level docstring explaining what it contains and why.
• Every new public class has a class docstring covering purpose, math/motivation, and key attributes.
• Every new public method / function has Args: and Returns: blocks with tensor shapes where applicable.
• Math notation is consistent with the paper (or a comment explains any deviation).
• Docstrings containing backslashes use r"""...""" (required by ruff D301).
• If a new file was added, a row has been added to docs-tracker.md with status [x].

See CONVENTIONS.md for the full style guide.
