// TestPreferExplicitAssert verifies testing-library prefer-explicit-assert:
// standalone presence queries are rejected.
//
// Locks the parent-shape check that distinguishes a bare `getBy*` query from a
// query used inside an assertion or expression. Standalone queries should not
// silently act as implicit assertions when this stricter rule is enabled.
//
//  1. Import `screen` from Testing Library.
//  2. Call a `getBy*` query as a standalone statement.
//  3. Assert `prefer-explicit-assert` reports the query call.
//
// @evidence contracts/testing.md#behavioral-verification The owning engine and Testing Library assertion helpers verify a standalone getBy query is reported; exact normalized findings reject extra or missing results.
// @evidence contracts/testing.md#independent-expectations With explicit assertions configured, getBy throwing is not the desired assertion form.
// @evidence contracts/testing.md#distinguishing-cases Wrapping the same query in a document assertion is accepted. The original violations remain intact and the authored adjacent source is asserted clean.
// @evidence contracts/testing.md#execution-ownership TestPreferExplicitAssert assertTestingLibraryFindings parses the source as TSX under a virtual component.test.tsx path and runs NewEngineWithResolver over it with only prefer-explicit-assert enabled: the standalone getByText source must yield one exact triple and the expect-wrapped source must yield none. No DOM runtime, installed consumer, native build or product child host runs.
