Handles the full archiving workflow when a change proposal is done and deployed. You tell it to archive, and it walks through eight steps: verifies implementation is complete, reviews the spec deltas (ADDED/MODIFIED/REMOVED requirements), creates a timestamped archive directory, merges each type of delta into your living specs, moves the change directory to archive, and validates the structure. The merge logic is specific: append for ADDED, replace entire blocks for MODIFIED, delete with optional comments for REMOVED. It's built for the openspec change management pattern where proposals live in spec/changes during development and get archived with their deltas merged back into spec/specs when shipped. Includes git commit strategies and troubleshooting for conflicts.
