What to change
Path casing can behave differently across hosting setups, so investigate the actual production behaviour before normalising links. Ask for examples of the variants already distributed through campaigns and documents. Agree one form for owned references and a deliberate compatibility rule where needed. Test the exact mixed-case address someone could copy from an old document rather than relying on a lowercased version of the test.
A worked example
Illustrative example
Illustrative test: Use a copied mixed-case campaign link and a normal library link.
How to check the result
Both journeys behave predictably and owned discovery files use the approved path casing.
A mistake to avoid
Assuming every server treats path casing identically can hide production-only faults.
