🟡 Changes recommended
Exclusions can remain unrecorded on send failures, and configuration resets introduce reliability and fleet-scale database risks.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
Adds certificate-renewal eligibility handling for Apple Business enrollment and hardware-attestation requirements.
Changes:
- Excludes ineligible SCEP renewals and routes eligible devices through ACME.
- Resets renewal state when enrollment settings change.
- Adds datastore operations and automated coverage.

WalkthroughThe change adds datastore methods and interface support for excluding certificate associations, clearing exclusions, and resetting pending renewals. Renewal queries now omit excluded associations and report DEP assignment. Apple MDM renewal processing filters associations according to SCEP, Apple Business enrollment, migration, DEP, and ACME eligibility. Relevant app configuration changes clear exclusions and reset pending renewals. Unit and integration tests cover datastore behavior, renewal routing, and configuration toggles. Merge Risk: 🔵 Low · up to DEP reassignment should restore certificate renewal eligibility. Add coverage for clearing the renewal exclusion so future changes do not silently regress that lifecycle behavior. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Full details: Linked Issues checkExplanation The implementation covers renewal exclusions, exclusion clearing, pending-renewal resets, DEP assignment reporting, enrollment-mode behavior, and toggle handling. The provided summary does not show the required starvation-guard test with more than 100 expiring associations, a dedicated re-enrollment test, or explicit coverage that DEP ingestion clears markers for only the ingested serials. Resolution Add or provide evidence for the starvation-guard test, re-enrollment/new-association behavior, and per-serial DEP-ingest marker clearing. Confirm that both DEP ingestion paths clear renewal_excluded_at within their existing transactions without affecting unrelated hosts.

Add an assertion for renewal exclusion clearing on DEP reassignment.
The existing UpsertMDMAppleHostDEPAssignments tests exercise reassignment, but none set and verify renewal_excluded_at. Add a test that seeds the exclusion, reruns the upsert, and verifies that the value is NULL.
