## 🔧 Technical Notes

### Branch Support

- ✅ All services must accept `BranchContext`
- ✅ All queries must filter by `currentBranchId`
- ✅ Child tables use cascade from quotations (no branchId needed)
- ✅ Topic defaults are global (no branchId)

### Data Types

- Use `numeric` for monetary values (precision 15, scale 2)
- Use `timestamp` for all dates
- Use `uuid` for all IDs
- Use `text` for flexible string fields

### Error Handling

- Validate branch ownership for all operations
- Return `null` for not found
- Throw `Error` for validation failures
- Use descriptive error messages

### Code Patterns

```typescript
// Standard pattern for all service methods
export async function methodName(
  context: BranchContext,
  ...params
): Promise<ReturnType> {
  const { currentBranchId, userId } = context;

  // Validate parent if needed
  const parent = await getParent(context, parentId);
  if (!parent) {
    throw new Error("Parent not found");
  }

  // Perform operation
  const [result] = await db.insert(table).values(data).returning();

  return result;
}
```

- [ ] Files can be uploaded, downloaded, and deleted
- [ ] All operations respect branch isolation
- [ ] Soft delete works correctly

### Phase 2 Verification

- [ ] Topics and topic items can be created and managed
- [ ] Follow-ups can be tracked
- [ ] Advanced search works with all filters
- [ ] Pagination works correctly
- [ ] Sorting works on all fields

### Phase 3 Verification

---

## 🚀 Getting Started

1. **Review this checklist** and understand the requirements
2. **Start with Phase 1.1** (Audit Trail Enhancement)
3. **Test each feature** before moving to the next
4. **Update this checklist** as you complete items
5. **Create unit tests** for critical business logic
6. **Document any deviations** from the plan

---

## 📝 Notes

- All implementations must follow existing patterns in the codebase
- Use TypeScript strict mode
- Add JSDoc comments for all public methods
- Run `npm run lint` before committing
- Test with both draft and sent quotations
- Verify multi-currency calculations
