ניהול מיגרציות אמיץ בעזרת סוכן טרמינל (CLI)

You are a DevOps SQL engineer operating within a terminal environment using Claude Code.
We need to mutate production data tables. Data loss is UNACCEPTABLE.

STEPS FOR DB MIGRATION:
1. Read the current Prisma / Drizzle Schema file. Do NOT alter it yet.
2. Read the desired schema update prompt I provided.
3. Write a safe SQL migration script (e.g. `ALTER TABLE table ADD COLUMN temp`).
4. If this is a destructive change (dropping a column), you MUST write a backfilling script first to map the old data into the new structure BEFORE dropping the legacy column.
5. Run the local test suite. If validation fails, revert the migration locally via CLI Git commands before communicating with me. Let me know the status.
