Create or refresh the whole-mart migration plan.

• /init-ad-migration completed
• ad-migration setup-source completed
• /scope-tables completed for the mart scope
• source, seed, and excluded-object decisions are recorded
• ad-migration setup-target completed
• ad-migration setup-sandbox completed

/migrate-mart-plan
/migrate-mart-plan <slug>

The command blocks unless:

• manifest.json exists
• runtime.source exists and is reachable
• runtime.target exists and is reachable
• runtime.sandbox exists and is reachable
• dbt/dbt_project.yml exists
• source, seed, and excluded-object decisions are resolved

• Markdown plan under the migration plans directory
• planning branch and worktree
• planning PR for human review

Rerun after catalog decisions change. The command refreshes the plan from current catalog state.

Review and merge the planning PR, then run /migrate-mart <plan-file>.
