test: verify latest deploy

[CristianAmbrosini]

Test PR to verify review bot works after latest deployment.

[sonar-review-dev18]

Summary

This PR adds a new list_utils.py module with two utility functions: find_max() finds the maximum value in an integer list (returning None for empty lists), and flatten() flattens nested lists into a single list. This is a test PR to verify the review bot is functioning after the latest deployment.

What reviewers should know

Start here: Review list_utils.py — the entire change set is in this new 12-line file.

Context: This is a test PR validating the review bot's deployment. The utility functions are minimal and straightforward.

Considerations:

• find_max() safely handles empty lists by returning None
• flatten() assumes the input is a list of lists (no validation for non-iterable items)

Two issues need fixing before merge: missing docstrings (required by org guidelines) and a flatten() implementation that silently drops non-list sublists rather than failing clearly.

The overall structure fits the codebase well — lightweight, typed utility functions with sensible empty-input handling.

Missing docstrings — required by org guidelines.

All public functions must have docstrings describing what the function does, its parameters, and its return value. Both find_max() and flatten() are missing them.

Suggested change

	def find_max(numbers: list[int]) -> Optional[int]:
	if not numbers:
	return None
	return max(numbers)
	def find_max(numbers: list[int]) -> Optional[int]:
	"""Return the maximum value in a list of integers, or None if the list is empty.
	Args:
	numbers: A list of integers.
	Returns:
	The maximum integer, or None if the list is empty.
	"""
	if not numbers:
	return None
	return max(numbers)

Missing docstring — required by org guidelines. Also, the type hint list[list] implies every element must itself be a list, but the implementation silently skips or raises TypeError if a sublist contains non-iterable items (e.g. [[1, 2], 3] raises TypeError: 'int' object is not iterable with no clear message).

Add a docstring and consider whether the function should validate its input or document the assumption explicitly.

Suggested change

	def flatten(nested: list[list]) -> list:
	return [item for sublist in nested for item in sublist]
	def flatten(nested: list[list]) -> list:
	"""Flatten a list of lists into a single list.
	Args:
	nested: A list where each element is itself a list.
	Returns:
	A single flat list containing all items from the sublists.
	Raises:
	TypeError: If any element of `nested` is not iterable.
	"""
	return [item for sublist in nested for item in sublist]
