Description

The phrase "has an interface dependency [...] prior to X" appears in [module.reach]p1 and [basic.start.dynamic]p1, but isn't defined. Per [module.import]p7, "has an interface dependency on" is a relation between translation units, with no associated "location" to be prior to.

It's obvious what it means: the interface dependency is caused by some construct (in this case, a module-declaration or module-import-declaration) that appears prior to X. But we should say that!

Research direction

Start by reading [module.reach]p1, [basic.start.dynamic]p1, and the definition in [module.import]p7. Trace how the phrase is used and clarify that the interface dependency is caused by a module-declaration or module-import-declaration appearing prior to X. Done means the wording explicitly defines the intended location relationship.
