ce-data-migration-reviewer

A data-migration & schema-change reviewer that evaluates migration work in three layers: schema drift / artifact risk, migration correctness (swapped mappings, missing backfills, deploy-window breaks, data loss), and verification & rollback (concrete SQL + a credible rollback path). It thinks in terms of the deploy window — old code on new schema, new code on old data, partial failures — and never trusts fixtures.

Dispatched by ce-plan, it implements stage-plan: on planning invocations it converts migration analysis into plan requirements (expand/contract sequencing, backfill/batching, dual-write, deploy-window risks). It pairs with ce-deployment-verification-agent (launch checklists) and ce-data-integrity-guardian (the validate/learn-side data reviewer).
