// TestCommandFixLeavesSuggestionOnlyRulesUnchanged verifies the disk-writing
// CLI keeps both upstream suggestions out of its automatic cascade while still
// reporting their diagnostics.
//
// @evidence contracts/testing.md#behavioral-verification Actual RunFix reports both await-thenable and ban-ts-comment errors with status two and empty stdout while preserving every original source byte instead of applying suggestion-only choices automatically.
// @evidence contracts/testing.md#independent-expectations Authored error-free ts-ignore target and await of a number independently trigger the two configured rules; original complete source bytes establish the required no-autofix outcome separately from rendered diagnostics.
// @evidence contracts/testing.md#distinguishing-cases Two distinct suggestion-only producers must both remain reported and untouched, contrasting with automatic cascades in the sibling fix unit; configured error severity prevents silence from satisfying preservation.
// @evidence contracts/testing.md#execution-ownership Real in-process command, checker-dependent rules and temporary file reads execute together without building native contributor sources, installing a consumer or invoking a CLI child.
