// TestPreferAsConstPreservesMigratedAllFamilyContexts verifies the preserved rule-family diagnostic set.
//
// Separates the original consumer case's portable semantics from package
// discovery while retaining its exact source and compiler settings.
//
// 1. Materialize the original source and compiler configuration.
// 2. Run the owning command operation with the scalar rule setting.
// 3. Compare every diagnostic rule, severity and line and failure status.
//
// @evidence contracts/testing.md#behavioral-verification The command reports all four literal-type visitor forms including parenthesized types, while leaving auto-accessors and differently spelled literals clean.
// @evidence contracts/testing.md#independent-expectations Authored lines 1, 2, 3 and 5 designate raw-matching literal annotations; differently quoted strings and hexadecimal spelling independently establish the negative expectations.
// @evidence contracts/testing.md#distinguishing-cases As assertions, angle assertions, variable annotations and ordinary class properties report; the accessor, mismatched quotes and hexadecimal spelling remain clean.
// @evidence contracts/testing.md#execution-ownership TestPreferAsConstPreservesMigratedAllFamilyContexts executes through assertMigratedTypedRuleCase and the owning Go command in the shared lint unit process. Fixture files require no native build or consumer installation; Package auto-discovery and native transport are not observed by this unit; current consumer survival requires separate E2E evidence.
