type:review

Review the migration-safety story for a data-layer change at stage-04d. Use this skill when the user says 'review this migration', 'is this rollback plan solid', '/migration-safety', or when the orchestrator invokes the migrations role for stage-04d. The skill walks schema delta → breaking-change classification → backfill strategy → dual-write strategy → rollback plan → rollback test → gate write. Has veto power on unsafe migrations.

From the source SKILL.md

A structured safety review for changes that touch persistent state (schema files, migration directories, ALTER/CREATE/DROP TABLE DDL, ORM migration files). Runs as stage-04d, conditional on stage-04a's heuristic firing.
