ksp-codegen generates unqualified type reference for @EmbeddedId inner class

[mobpolice]

• I am willing to put in the work and submit a PR to resolve this issue.

Describe the bug
When @EmbeddedId is declared as an inner class of a JPA entity,
ksp-codegen generates an unqualified type reference that fails to compile.

To Reproduce
Add a JPA entity with an @EmbeddedId declared as an inner class:

@Entity
class Invoice(
    @EmbeddedId val id: InvoiceId
) {
    @Embeddable
    data class InvoiceId(
        val invoiceNo: String = "",
        val seq: Int = 0
    ) : Serializable
}

Running kspKotlin generates QInvoice_InvoiceId.kt with an unqualified type reference that fails to compile.

Generated (wrong)

BeanPath<InvoiceId>  // cannot be resolved

Expected

BeanPath<Invoice.InvoiceId>  // correct qualified reference

Root cause

QueryModelExtractor.toQueryModel() builds originalClassName using only classDeclaration.simpleName, which drops the enclosing class from the generated type reference.

Thanks for the clear repro and for narrowing this to the KSP model extraction path. I’ve labeled it as a bug.

The compatible fix here should keep the generated names for top-level types unchanged, while qualifying nested @Embeddable id classes like Invoice.InvoiceId when KSP reports an enclosing declaration. A PR with a regression test around an @EmbeddedId inner class would be the right way to move this forward, and I’ll review it.
