// TestNoEmptyStaticBlockCommentBoundaries ensures only comments between the
// static block's own braces make the empty block intentional.
//
// @evidence contracts/testing.md#behavioral-verification Reports empty static blocks and ignores only comments inside the static braces or actual statements.
// @evidence contracts/testing.md#independent-expectations Authored seven counts follow the supported intentional-empty policy; surrounding class comments are not interior evidence.
// @evidence contracts/testing.md#distinguishing-cases Interior block/line comments contrast with leading/trailing/before-brace comments, empty and nonempty bodies.
// @evidence contracts/testing.md#execution-ownership This Test registers each of the seven static-body rows with t.Run; runRuleFindingsSnapshot executes no-empty-static-block and the named subcase compares its authored count. Execution stays in the lint Go process without consumer installation or native product-host builds/launches.
