Implements the Stable and Experimental JPA persistence platform designs
against real PostgreSQL, adapted to this repository's fail-closed 19-leaf
registry.
The design models the platform as 25 Gradle projects. `src/settings.gradle`
throws unless the registry holds exactly 19 leaves, so the plan's modules
become packages inside `:adapter:outbound:persistence-jpa` (starter in
`:app-bootstrap`, testkit in its own source set). The full mapping, the
renames this repository's naming gate required, and every deliberate
substitution are recorded in `docs/jpa/repository-adaptation.md`.
Seven Docker-backed lanes replace the plan's seven JVM test suites. Each
fails closed: a lane that discovers nothing, or a container that cannot
start, is an error rather than a skip.
Three defects the contracts found against a real server:
- `CommitFailureClassifier` treated only SQLSTATE 40003, class 08, and
transport breaks as completion-unknown. A backend terminated mid-commit
reports 57P01, and the commit record may already be in the WAL — so a
possibly-committed transaction could be re-run. 57P01/57P02/57P03 now
classify as completion-unknown.
- `SchemaTenantMigrationOrchestrator` recorded `MigrateResult`'s target
version, which is empty for a tenant already current, reporting migrated
tenants as unmigrated during a partial rollout. It now reads the applied
version back from the tenant's schema history.
- `JpaStreamExecutor` checked only the declared return type for reactive
publishers, and `RegisteredPostgreSqlCopyLoader` passed the COPY timeout
to `SET`, which is parsed before parameter binding.
`JpaModuleBoundaryTest` enforces the plan's module map as package rules;
`verifyCleanArchitectureDependencies` governs edges between leaves and
cannot see these. Its first assertion is that the import is non-empty,
because every rule under it is a `noClasses()` rule and would pass
vacuously on an empty import.
Verified: 128 container tests across all seven lanes, 1183 unit tests,
`:adapter:outbound:persistence-jpa:check`, `:app-bootstrap:check`,
`verifyCleanArchitectureDependencies`, `verifyOneTypePerFile`.

Snapshot of the in-flight state that already existed, identically, in both
this worktree and the main checkout before this session began: the initial
HTTP Client platform implementation (previously untracked), the redis-lab
removal, and the JPA / object-storage / notification integration work.
Kept separate from this session's HTTP Client review response, which lands
in the following commit, so the two bodies of work stay reviewable apart.
