Decisions

• Decide whether repo ownership matching is attempted in v1.
• Decide JSON and human output shape.
• Decide whether Item 8 includes linking existing changes.
• Decide whether status/instructions surface initiative links.
• Confirm latest suggested resolutions in plan.md before implementation.

Implementation
