## Summary
- Refactored the conditional access policy query to use `CONCAT('%', ?,
'%')` with a bound parameter instead of string concatenation for the
platform `LIKE` clause, consistent with how other queries in this file
handle string filters.
## Test plan
- [ ] Verify conditional access policy lookup still returns correct
results for macOS/Windows hosts.
- [ ] Confirm no regression in policy filtering behavior.
