xchecker 1.2.0

//! CLI integration tests for fixup command (Task 4.7)
//!
//! **WHITE-BOX TEST**: This test uses internal module APIs (`orchestrator::{OrchestratorConfig,
//! PhaseOrchestrator}`, `types::PhaseId`) and may break with internal refactors. These tests are
//! intentionally white-box to validate internal implementation details. See FR-TEST-4 for
//! white-box test policy.
//!
//! This test validates the complete CLI integration for fixup:
//! - `xchecker resume <spec-id> --phase fixup` command works
//! - `xchecker resume <spec-id> --phase fixup --apply-fixups` command works
//! - Receipt is written with fixup results
//! - Fixup artifacts are created

## Analysis

The requirements document needs an additional requirement.

## FIXUP PLAN:

The following changes are needed:

```diff
--- a/artifacts/00-requirements.md
+++ b/artifacts/00-requirements.md
@@ -2,3 +2,6 @@
 
 ## Requirement 1
