Warnings fixed (13 issues): - Replace expensive length/1 checks with empty list comparisons - Remove redundant n == n comparison in is_finite guards - Use proper type notation in @spec instead of struct literal Design suggestions (3/13 files): - Add aliases for nested modules in historical_loader, page_controller, mobile_channel Remaining: 10 design suggestions, 42 refactoring opportunities (complex functions)
