Follow the shared source-of-truth, permission and evidence rules in `../../references/workflow-contract.md`. Read `../../references/migration-safety.md` for detailed method when necessary.\n\n## Procedure\n1. Inventory producers, consumers, retained data and backward-compatibility commitments.\n2. Choose expand/contract or versioned contract strategy, with validation and defaults.\n3. Plan safe migration order, dual-compatibility period, idempotent backfills and restore strategy.\n4. Test both old and new consumers and failure/rollback cases when possible.\n5. Obtain approval for destructive steps, broad backfills or production writes.\nDeliver migrations and tests with explicit compatibility risks.\n\n## Handoff rule\nState actual artifacts or grounded code findings and validation status. Never invent file paths, executed tests, tool access, or completed subagent work. Keep output proportionate to the user request.\n"
