False positives for data classes that reference data classes from foreign modules

[ursusursus]

I have a data class that is at presentation layer, that references my data class Url(val value: String) that is from a different module

data class AttemptsExceededViewModel.State(
        val eShopOfferUrl: Url? = null
)

the compose output is

unstable class foo.bar.AttemptsExceededViewModel.State {
  unstable val eShopOfferUrl: Url?
  <runtime stability> = Unstable
}

I assume due to the different module locality

yet IDE plugin says it's all stable

A summary of the changes CodeRabbit can apply:

• Add STABILITY_INFERRED_FQ to StabilityConstants.kt, modify getStabilityInferredParameters() to detect @StabilityInferred and return -1 for runtime-checked cases, and update the stability-decision logic to treat -1 as "Annotated with @StabilityInferred (from separate compilation)" so the IDE marks foreign-module types as runtime-unstable.

• Add STABILITY_INFERRED_FQ to StabilityConstants and update KtStabilityInferencer to detect @StabilityInferred (returning N, -1 when present but unreadable, or null when absent), change the stability branch to treat parameters>0 as runtime-stable and handle the cross-module (unreadable) case as "Annotated with @StabilityInferred (from separate compilation)".

Hi! For now, there’s no explicit way to distinguish between different modules, since the IDEA plugin relies on your IDE environment rather than a specific module. Also, that data class can still be considered stable within the same package, which could make things more confusing if we introduced a sort of “primary module” setting or something similar.

I’ll look into possible approaches to improve this and see if there’s a better way to handle it.
