# Phase 23 Plan 00: Foundation — DB Migration, Shared Types, Test Stubs Summary
**One-liner:** Added message_type nullable text column via SQL migration 0049, extended ChatMessage type and createMessageSchema, added handoffSchema with nested spec/targetRole structure, and created 5 Wave 0 it.todo() test stub files covering all Phase 23 components.
## Tasks Completed
| Task | Name | Commit | Files |
|------|------|--------|-------|
| 1 | DB migration and shared types for message_type | 6e436950 | chat_messages.ts, 0049_add_message_type.sql, _journal.json, types/chat.ts, validators/chat.ts, index.ts |
| 2 | Wave 0 test stubs for Phase 23 components and hooks | 588bbdd5 | ChatSpecCard.test.tsx, ChatHandoffIndicator.test.tsx, ChatTaskCreatedBadge.test.tsx, ChatStatusUpdateBadge.test.tsx, useBrainstormerDefault.test.ts |
## Verification
- `pnpm exec tsc --noEmit` passes for shared and db packages
- Migration file 0049 exists with correct SQL (`ALTER TABLE "chat_messages" ADD COLUMN "message_type" text;`)
- Journal updated with idx 47, 48, 49 entries
- All 5 test stub files parseable and found by vitest (23 todo tests, 0 failures)
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 1 - Bug] Journal entries for idx 47 and 48 were missing**
- **Found during:** Task 1 — reading _journal.json showed last entry was idx 46, but files 0047 and 0048 exist on disk
- **Issue:** The plan noted this ambiguity and directed: add entries for 47, 48, AND 49 to keep journal consistent
- **Fix:** Added retroactive entries for idx 47 (`0047_nebulous_klaw`) and idx 48 (`0048_add_chat_messages_updated_at`) with approximate timestamps, plus the new idx 49 entry
- **Files modified:** packages/db/src/migrations/meta/_journal.json
- **Commit:** 6e436950
## Known Stubs
None — all test stubs are intentional Wave 0 scaffolding using it.todo() per Phase 21 convention. They are designed to be implemented in subsequent plans 23-01 through 23-03.
## Self-Check: PASSED
