## Verdict: 🔄 Request changes
The account-scoping intent is good, but there are three issues to address before merging.
### Required changes
1. **[blocking · security] Parameterize the query.**
`q` is interpolated directly into SQL. A crafted search term can change the query’s logic, potentially bypassing the `account_id` restriction and exposing other accounts’ orders. Even an ordinary name such as `O'Brien` can break the query.
Bind the account ID, search pattern, limit, and offset using the database driver’s parameter API. Build the pattern as a parameter value—not as part of the SQL string.
2. **[blocking · correctness] Fix the 1-based page offset.**
`offset = page * PAGE_SIZE` makes page 1 skip the first 20 orders. Use:
```python
offset = (page - 1) * PAGE_SIZE
```
3. **[important · input validation] Reject invalid page values with a 400 response.**
`int(...)` raises an unhandled `ValueError` for values such as `page=abc`, producing a server error. Zero and negative pages are also accepted, leading to incorrect pagination or database errors. Catch conversion failures and require `page >= 1` before executing the query.

### Additional feedback
- **[important · pagination] Add a unique tie-breaker:** use `ORDER BY created_at DESC, id DESC`. Orders with identical timestamps otherwise have no guaranteed relative order, so page boundaries can produce duplicates or omissions even without data changes.
- **[question · authorization] Does `login_required` also enforce admin access?** The snippet establishes authentication and intends account scoping, but doesn’t show an admin permission check. If admin access isn’t enforced elsewhere, add the appropriate authorization guard.
- **[question · search semantics] Should `%` and `_` be literal characters?** Parameterization prevents SQL injection, but these characters still act as `ILIKE` wildcards. Escape them if the intended behavior is literal substring matching.
### Tests to add
- Default page and explicit page 1 return the first 20 results; page 2 returns the next 20.
- Invalid, zero, and negative pages return 400.
- Names containing apostrophes work, and injection-like input cannot bypass account isolation.
- Other accounts’ orders are excluded.
- Equal timestamps have deterministic ordering.
- Unauthenticated—and, if applicable, non-admin—requests are rejected.
