Description
Is it possible to configure HLint to ensure that each time a ToJSON/FromJSON instance is written (hand-written or auto-derived), there is a property-based test added for it as well?
Generalizing this question:
- can HLint work across files?
- can HLint ensure that a function's docs are updated if its type-signature is changed?

Research direction
No files, tests, or entry points are named. Start by reviewing how HLint represents and applies checks, then determine whether cross-file analysis can support ToJSON/FromJSON test requirements and documentation updates tied to type-signature changes. Done means a concrete, agreed scope for these capabilities.
