JVM Core

Shared model for the jvm cluster. The framework, persistence, testing, security, and verification spokes all depend on these decisions — keep them consistent here so no spoke contradicts another.

1. The decision this cluster turns on: language × framework

Every JVM service starts with two choices, and they cascade into which spokes apply:

Language ──┐
           ├──> Framework ──> Patterns + TDD + Security + Verification spokes
Persistence┘

• Language — Kotlin (null-safe, coroutines, DSLs → kotlin-patterns) or Java (immutable-by-default, streams, records → java-coding-standards). Pick one per module.

• Framework — the heart of the decision:
