Track Specification: Advanced Tier 4 QA Auto-Patching (tier4_auto_patching_20260306)

Overview

Elevate Tier 4 from log summarizer to auto-patcher. When verification tests fail, Tier 4 generates a .patch file. GUI displays side-by-side diff; user clicks Apply Patch to resume pipeline.

Architectural Constraints

• Safe Preview: Patches MUST be previewed before application.
• Rollback: Failed patches MUST be revertable.
• Atomic Application: Patch application MUST be atomic (all-or-nothing).

Functional Requirements

• Patch Generation: Tier 4 generates .patch file on test failure.
• Diff Viewer: GUI shows side-by-side diff of proposed changes.
• Apply Button: User confirms patch application.
• Patch Application: Apply patch to working directory and verify.

Acceptance Criteria

• Tier 4 generates valid .patch file.
• GUI displays readable side-by-side diff.
• User can approve/reject patch.
• Approved patches applied correctly.
• Rollback available on failure.
