WalkthroughThe synchronization controller now applies success conditions to existing MAPI machines when available. New MAPI machines still receive conditions on converted objects. Integration tests verify transition-time preservation in both synchronization directions. ChangesMachine synchronization
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: ⚪ Minimal · up to The change preserves the Synchronized condition transition time during repeated reconciliations, with no actionable merge-blocking risk remaining beyond a minor test-message follow-up.

Full details: Stable And Deterministic Test NamesExplanation PASS: The pull request adds two Ginkgo test titles, and both use fixed string literals: "should preserve the Synchronized condition lastTransitionTime on subsequent successful syncs". The added Full details: Test Structure And QualityExplanation The added Ginkgo tests lack meaningful assertion messages. Both new tests use bare Resolution Add meaningful failure messages to every assertion in both new tests.

They trigger reconciliation with a label or provider-spec change and verify condition timestamps. They do not count nodes, schedule pods, use topology or affinity rules, test failover, drain, scaling, or require separate hosts. No SNO guard is required.

The production diff only changes which MAPI object supplies the synchronized condition. The shared status helper reads condition data and patches status; it does not log object contents. Added tests use non-sensitive labels and instance types.

…PI-to-MAPI sync In the CAPI-to-MAPI success path, `convertedMAPIMachine` was passed to `applySynchronizedConditionWithPatch`. In steady-state reconciliations (no status or spec changes detected), `ensureMAPIMachineStatusUpdated` returns early before copying existing conditions into `convertedMAPIMachine`, leaving its `Status.Conditions` empty. This caused `SetLastTransitionTime` to treat the Synchronized condition as new and reset it to `Now()` on every sync. Fix by using `existingMAPIMachine` (which carries the live conditions from the cluster) when it is non-nil, falling back to `convertedMAPIMachine` only for newly created machines where no prior condition exists. Add integration tests for both MAPI-to-CAPI and CAPI-to-MAPI directions that confirm `lastTransitionTime` is preserved across successive successful reconciliations.
