`orbit/changes/` or `ee/fleetd-chrome/changes`.
See [Changes
files](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/guides/committing-changes.md#changes-files)
for more information.
- [x] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements), JS
inline code is prevented especially for url redirects, and untrusted
data interpolated into shell scripts/commands is validated against shell
metacharacters.

loops
- [x] If paths of existing endpoints are modified without backwards
compatibility, checked the frontend/CLI for any necessary changes
## Testing

- [x] Where appropriate, [automated tests simulate multiple hosts and
test for host
isolation](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/reference/patterns-backend.md#unit-testing)
(updates to one hosts's records do not affect another)
- [x] QA'd all new/changed functionality manually

## Summary by CodeRabbit
* **Bug Fixes**
* Improved device lock handling so only active pending lock commands are
treated as valid.
* Fixed stale lock state cases where an old lock reference no longer
blocks a new lock request.
* When a prior lock command is no longer deliverable, a new lock command
is now issued and tracked correctly.
* Updated coverage to verify lock status transitions and replacement
behavior in these edge cases.
