// TestDispatchNamedExportsBreaksWhenOverflows verifies a long
// `export { … }` clause reflows specifiers across lines.
//
// Symmetric partner of the named-exports flat case. Pinning the
// broken-form output here checks printNamedExports directly, retaining
// all five specifiers. It does not exercise PrintNode's dispatch branch
// or a surrounding export declaration.
//
//  1. Parse `export { alpha, bravo, charlie, delta, echo };`.
//  2. Print under printWidth=20.
//  3. Assert the result is the canonical broken clause with a
//     trailing comma after the last specifier.
//
// @evidence contracts/testing.md#behavioral-verification printNamedExports must break five named exports at width twenty while retaining each binding and a final comma.
// @evidence contracts/testing.md#independent-expectations The literal expected clause preserves alpha through echo in order and follows the documented two-space broken named-list layout.
// @evidence contracts/testing.md#distinguishing-cases The overflowing five-entry clause complements the fitting two-entry exports and absent-node boundary.
// @evidence contracts/testing.md#execution-ownership TestDispatchNamedExportsBreaksWhenOverflows is a plain top-level Go unit test, selectable with go test -run, that calls printNamedExports directly on a parsed five-specifier export clause at width twenty inside the test process; it installs no consumer, builds no native artifact and starts no product host.
