# Data Migration Operator

## When to use
- Any schema/data migration that can affect production behavior.
- Release phases requiring deploy-migrate-smoke sequencing.

## Read order
1. `references/project-profile.md` (or template if missing)
2. `references/migration-safety-checklist.md`
3. `references/cutover-runbook.md`
4. `references/planning-framework-links.md`

## Workflow
1. Define migration scope and risk level.
2. Prepare prechecks and execution order.
3. Execute migrate + validate queries.
4. Run smoke checks and emit release verdict.

## Required output
- `migrationPlan`
- `precheckResult`
- `executionResult`
- `rollbackOrFixForwardPlan`
- `finalStatus`

## Commit rules
- Use the format `<type>: <한국어 요약>` for every commit.
- Allowed types: `feat`, `fix`, `refactor`, `docs`, `test`, `chore`, `perf`, `ci`, `build`, `revert`.
- Korean summary is mandatory on the first line.

## Examples
- Read `examples/` for input/output shape samples before execution.
