+### 3. ByteBuddy Proxy Initialization & Interception (In Progress)
**Symptoms:**
-- `ByteBuddyGroovyInterceptorSpec` and `HibernateProxyHandler7Spec` failures.
+- `ByteBuddyGroovyInterceptorSpec` and `ByteBuddyProxySpec` failures.
- Proxies are initialized prematurely during `getId()`, `isDirty()`, or Groovy
internal calls.
**Description:**
Hibernate 7's `ByteBuddyInterceptor.intercept()` does not distinguish between
actual property access and Groovy's internal metadata calls (like
`getMetaClass()`). This triggers hydration during common Groovy operations.
+**Current Status:**
+- Modified `ByteBuddyGroovyInterceptor` to explicitly intercept `getId`,
`getIdentifier`, `getMetaClass`, `getProperty("id")`, and `isDirty` without
triggering proxy hydration.
+- The unit test `ByteBuddyGroovyInterceptorSpec` is now fully green, bypassing
the `SessionException` via a more comprehensive mock chain.
+- The integration test `ByteBuddyProxySpec` still fails for `@CompileStatic`
method invocations. Hibernate 7's internal `this.invoke()` call within the
interceptor eagerly initializes the proxy. I moved the identifier checks
*before* `this.invoke()` to bypass Hibernate's standard interception logic for
these specific methods, and am currently running tests to verify.
