Since beads is designed to be run by AI agents, we should leverage AI to make migrations safer.\n\n## Current State\n\nMigrations run blindly with:\n- No pre-flight validation\n- No data integrity verification\n- No rollback on failure\n- Limited post-migration testing\n\nRecent issues:\n- GH #201: Migration didn't set issue_prefix config, breaking commands\n- bd-d355a07d: False positive \"data loss\" warnings on collision resolution\n- Users reported migration data loss (fixed but broader problem remains)\n\n## Proposal: AI-Supervised Migration Framework\n\nUse AI to supervise migrations through structured verification:\n\n### 1. Pre-Migration Analysis\n- AI reads migration code and current schema\n- Identifies potential data loss scenarios\n- Generates validation queries to verify assumptions\n- Creates snapshot queries for before/after comparison\n\n### 2. Migration Execution\n- Take database backup/snapshot\n- Run validation queries (pre-state)\n- Execute migration in transaction\n- Run validation queries (post-state)\n\n### 3. Post-Migration Verification\n- AI compares pre/post snapshots\n- Verifies data integrity invariants\n- Checks for unexpected data loss\n- Validates config completeness (like issue_prefix)\n\n### 4. Rollback on Anomalies\n- If AI detects data loss, rollback transaction\n- Present human-readable error report\n- Suggest fix before retrying\n\n## Example Flow\n\n```\n$ bd migrate\n\n→ Analyzing migration plan...\n→ AI identified 3 potential data loss scenarios\n→ Generating validation queries...\n→ Creating pre-migration snapshot...\n→ Running migration in transaction...\n→ Verifying post-migration state...\n✓ All 247 issues accounted for\n✓ Config table complete (issue_prefix: \"mcp\")\n✓ Dependencies intact (342 relationships verified)\n→ Migration successful!\n```\n\nIf something goes wrong:\n```\n$ bd migrate\n\n→ Analyzing migration plan...\n→ AI identified issue: Missing issue_prefix config after migration\n→ Recommendation: Add prefix detection step\n→ Aborting migration - database unchanged\n```\n\n## Implementation Ideas\n\n### A. Migration Validator Tool\nCreate `bd migrate --validate` that:\n- Simulates migration on copy of database\n- Uses AI to verify data integrity\n- Reports potential issues before real migration\n\n### B. Migration Test Generator\nAI generates test cases for migrations:\n- Edge cases (empty DB, large DB, missing config)\n- Data integrity checks\n- Regression tests\n\n### C. Migration Invariants\nDefine invariants that AI checks:\n- Issue count should not decrease (unless collision resolution)\n- All required config keys present\n- Foreign key relationships intact\n- No orphaned dependencies\n\n### D.

Since beads is designed to be run by AI agents, we should leverage AI to make migrations safer.\n\n## Current State\n\nMigrations run blindly with:\n- No pre-flight validation\n- No data integrity verification\n- No rollback on failure\n- Limited post-migration testing\n\nRecent issues:\n- GH #201: Migration didn't set issue_prefix config, breaking commands\n- bd-d355a07d: False positive \"data loss\" warnings on collision resolution\n- Users reported migration data loss (fixed but broader problem remains)\n\n## Proposal: AI-Supervised Migration Framework\n\nUse AI to supervise migrations through structured verification:\n\n### 1. Pre-Migration Analysis\n- AI reads migration code and current schema\n- Identifies potential data loss scenarios\n- Generates validation queries to verify assumptions\n- Creates snapshot queries for before/after comparison\n\n### 2. Migration Execution\n- Take database backup/snapshot\n- Run validation queries (pre-state)\n- Execute migration in transaction\n- Run validation queries (post-state)\n\n### 3. Post-Migration Verification\n- AI compares pre/post snapshots\n- Verifies data integrity invariants\n- Checks for unexpected data loss\n- Validates config completeness (like issue_prefix)\n\n### 4. Rollback on Anomalies\n- If AI detects data loss, rollback transaction\n- Present human-readable error report\n- Suggest fix before retrying\n\n## Example Flow\n\n```\n$ bd migrate\n\n→ Analyzing migration plan...\n→ AI identified 3 potential data loss scenarios\n→ Generating validation queries...\n→ Creating pre-migration snapshot...\n→ Running migration in transaction...\n→ Verifying post-migration state...\n✓ All 247 issues accounted for\n✓ Config table complete (issue_prefix: \"mcp\")\n✓ Dependencies intact (342 relationships verified)\n→ Migration successful!\n```\n\nIf something goes wrong:\n```\n$ bd migrate\n\n→ Analyzing migration plan...\n→ AI identified issue: Missing issue_prefix config after migration\n→ Recommendation: Add prefix detection step\n→ Aborting migration - database unchanged\n```\n\n## Implementation Ideas\n\n### A. Migration Validator Tool\nCreate `bd migrate --validate` that:\n- Simulates migration on copy of database\n- Uses AI to verify data integrity\n- Reports potential issues before real migration\n\n### B. Migration Test Generator\nAI generates test cases for migrations:\n- Edge cases (empty DB, large DB, missing config)\n- Data integrity checks\n- Regression tests\n\n### C.
