Description
The section on linting describes how to declare a lint and how lint passes are constructed, but we are still missing an explanation on how the lint system takes buffered lints and decides whether to actually emit them to users. For instance, how does --cap-lints work?

Research direction
Start with the existing linting section and trace how buffered lints are selected for emission, including the behavior of --cap-lints. Document the emission decision process and explain how the cap affects what users see; done means the guide covers this path clearly alongside lint declaration and lint-pass construction.
