• [ ] If paths of existing endpoints are modified without backwards compatibility, checked the frontend/CLI for any necessary changes

Testing

• [ ] Added/updated automated tests

• [ ] Where appropriate, automated tests simulate multiple hosts and test for host isolation (updates to one hosts's records do not affect another)

• [ ] Confirmed that the fix is not expected to adversely impact load test results
• [ ] Alerted the release DRI if additional load testing is needed

Database migrations

• [ ] Checked schema for all modified table for columns that will auto-update timestamps during migration.

• [ ] Ensured the correct collation is explicitly set for character columns (COLLATE utf8mb4_unicode_ci).

New Fleet configuration settings

• [ ] Setting(s) is/are explicitly excluded from GitOps

If you didn't check the box above, follow this checklist for GitOps-enabled settings:

• [ ] Verified that the setting is cleared on the server if it is not supplied in a YAML file (or that it is documented as being optional)
• [ ] Verified that any relevant UI is disabled when GitOps mode is enabled

fleetd/orbit/Fleet Desktop

• [ ] Verified compatibility with the latest released version of Fleet (see Must rule)
• [ ] If the change applies to only one platform, confirmed that runtime.GOOS is used as needed to isolate changes

@lucasmrod Going to stack additional tests in another PR since this one's massive. Added TODOs on where I believe we want more test coverage. Adding that checklist to the parent issue momentarily.
