Change Control

Change Control

This skill records requirement changes, calculates impacted artifacts, marks stale downstream contracts, invalidates approvals, and regresses to the earliest impacted stage.

Input Artifacts

• User change request
• 00-stage.json
• 00-artifact-registry.json
• Existing approved artifacts

Output Artifact

• docs/full-stack-development/requirements/<feature-slug>/changes/<change-id>-change-request.md

Required MCP Tool

• plan_change_impact
• mark_artifacts_stale
• plan_requirement_change
• review_stage_gate

Hard Stops

• Do not directly edit code after a requirement change.
• Do not keep old visual approval when IA, interaction, state, visual, frontend, API, or product contracts changed.
• Do not keep implementation approval when behavior or engineering contracts changed.

Pressure Test Responsibility

• Role changes regress to product scope.
• Field/action/state changes regress to IA, interaction, and state.
• API/auth changes regress to backend/API/frontend contract.
• Acceptance command changes regress to verification.

Next Gate

• Re-run review_stage_gate for the regressed stage before design or implementation continues.
