# JPA Test Lanes Java Convention Plan

**Goal:** Remove the remaining Map-driven JPA lane factories from Groovy and make lane metadata compile-time checked Java records.

**Architecture:** `ca.jpa-test-lanes` lives in build-logic and configures `ca.strict-test-lane`. Typed record lists own the PostgreSQL readiness and tagged platform lane metadata. The JPA leaf keeps source-set/dependency declarations plus the explicit cross-project task edge.

## Constraints
- Preserve all 14 PostgreSQL readiness task names and selectors.
- Preserve the security method selector in addition to its class selector.
- Preserve five tagged platform lanes and the pool contract lane.
- Preserve UTC JVM args, PostgreSQL evidence image property, and `jpa.matrix.versions` default `16`.
- Keep release orchestration outside the leaf.
- Do not stage, commit, amend, or push.

## Steps
- [ ] RED TestKit contract for registered lanes, typed selector metadata, and property defaults.
- [ ] Implement Java record-backed `JpaTestLanesPlugin` and register `ca.jpa-test-lanes`.
- [ ] Apply plugin in persistence-jpa and remove both Groovy `Map` factories plus pool-lane Groovy configuration.
- [ ] Run focused build-logic tests, JPA check, adapter dynamic-model scan, and broad verification.
