A mechanical prettier --write over server/src, server/tests, server/scripts and shared/src with the workspaces' .prettierrc; nothing but layout and import order changes, and every file keeps the same set of imports. shared is formatted throughout and its format baseline is empty. The server baseline keeps the 35 files that Prettier would grow past their lint:size limit (they need a split first, which is not a formatting change), and the generated entity files stay as their generator writes them.

* D5 ratchet (task-6-fix-brief.md item 2; task-1-2-rereview.md's "half that
|
|
* IS testable"): the property `test-uow.ts`'s one-ORM-per-handle wiring
|
|
* exists to protect is not "the split (two-ORM) wiring was broken" — measured
|
|
* and disproven in that re-review, since `TransactionContext.getEntityManager`
|
|
* matches on the EntityManager's CONTEXT NAME, not the ORM instance, so even
|
|
* a repository built from a second `MikroORM.init` over the same handle
|
|
* resolves the open transaction correctly. The property that IS real, and
|
|
* WAS previously unpinned by any test, is global-context-resolving EM vs a
|
|
* manually forked one: a fork defaults to `useContext: false`, so its
|
|
* `getContext()` returns itself and ignores `TransactionContext` — a
|
|
* repository built on a fork used inside `uow.transactional(...)` would
|
|
* write outside the open transaction, on a second connection the
|
|
* transaction is holding.
