JPA Spring Data Kotlin Mapper

Source mapping: Tier 1 critical skill derived from Kotlin_Spring_Developer_Pipeline.md (SK-10).

Mission

Generate and review persistence mappings that are correct for both Hibernate semantics and Kotlin semantics. Prevent bugs that compile cleanly but fail under lazy loading, dirty checking, identity comparison, or query load.

Read First

• Entity classes and mapped superclasses.
• Repository interfaces and custom queries.
• Relevant service methods and transaction boundaries.
• SQL logs, execution plans, or symptoms such as N+1, deadlocks, or stale reads.
• Build files to verify JPA-related Kotlin compiler plugins.
