Resolve these status issues before merging. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The normal readiness-to-availability mapping preserves the intended user-facing contract. However, existing objects can retain obsolete health conditions, and a recovered Helm installation can retain Available=False. These are bounded status and recovery-contract risks; the inspected changes do not demonstrate expanded privileges or bypassed security controls. Retained concerns

- Line 665: In Reconcile, remove the legacy Available condition from the
deep-copied ClusterObjectSet status immediately after copying it, before any
reconciliation path runs, so the removal is persisted even when Ready is not
written. Add an upgrade test that starts with a persisted Available condition
and verifies it is removed.

Question for future: are we planning to do a similar Reason review/re-mapping to remap from COS/COD to CE? Or do we expect the CE's Available condition reasons to be directly plumbed from the lower-level API?

In this case, I wonder if we aren't better off taking the new reasons tbh - idk if the juice is worth the squeeze here in terms of keeping parity (and Available is not released on the CE anyway). Wdyt?

Well I just wonder if the semantics are slightly different because now this is a condition over multiple ClusterObjectSets (or eventually over a single COD).
Once we have the COD aggregating across COSes, it becomes much easier to justify "just plumb from the COD", I think?
But even then, CE might need a few more reasons e.g. for a case like the COD itself not having a status yet.

Interestingly, we didn't document the Available condition in the CE CRD (even under experimental). What if we drop it for now (in a follow-up) and think about re-introducing it after we have COD in the mix?

the issue with trying to do the mapping as it is would be that we'd need to wait for Dan's changes to land before we could do a proper mapping. Maybe we could still have a mapping but change the names of the reasons away from the probe verbiage. Or maybe AllObjectsReady -> ClusterObjectSetReasonProbesSucceeded, and other reasons -> RevisionNotReady or something like that =/ I'm not super happy about that though...

Adding Available here also changes ensureFailureConditionsWithReason()🔗, which loops over this list and creates missing conditions as False. So we now get a new default Available=False condition.
That helper is shared by the Helm and Boxcutter runtimes. If catalog resolution fails during a Helm installation, it now creates Available=False/Retrying. When resolution recovers and installation succeeds, Helm updates Installed and Progressing but never updates Available, leaving the extension reporting unavailable with the old error indefinitely.

that's a great catch! Thank you! I've removed it from the condition types slice!

I'm skipping the Available condition in ensureFailureConditionsWithReason for now. I guess this is the current behavior before introducing the TypeAvailable condition here anyway.

This feels like something I may have wrote or contributed to early on to satisfy the API convention of "always populate all conditions, even if it is just to set Unknown.
But honestly, we should consider dropping or at least majorly reconsidering the approach of automatically filling in Conditions with a shared reason. Seems like we should have an explicit set of possible condition Type/Status/Reason tuples that are valid, and there should be no "just fill in the blanks" sort of logic.
…vailable
Decouple the ClusterExtension status contract from the internal
ClusterObjectSet (COS) condition vocabulary.
Previously both COS and ClusterExtension (CE) used a condition type named
Available, and the operator-controller reader copied the COS Available
condition straight through to the CE, coupling the user-facing CE contract
to a COS implementation detail.
Now:
- ClusterObjectSet reports its health through a Ready condition instead of
Available (aligns with the ReplicaSet/Pod-style layering where the lower
layer is Ready and the higher layer is Available). The printer column is
renamed accordingly.
- ClusterExtension continues to expose a stable Available condition. The
reader reads the COS Ready condition and re-types it to the CE-owned
Available condition (new ocv1.TypeAvailable constant) before publishing,
so the COS Ready type never leaks onto the ClusterExtension.
The condition rename does not change the CRD schema (conditions is a generic
list); only the COS printer column and field descriptions change. CRDs,
manifests, and applyconfigurations are regenerated.
Test: TestSetAvailableFromRevisionStates is a table-driven test over
setAvailableFromRevisionStates asserting the COS Ready -> CE Available
remap, status/reason/message/generation carry-through, and that the COS
Ready type is never surfaced on the ClusterExtension.
