Nice work on this one, the early-failure handling in the deferred status patch is well thought out, and the doc splitting the operator-layer vocabulary from the API-layer one is going to save a lot of confusion later. Couple of points below worth addressing, two of them I'd like sorted before merge, the rest are follow-ups or nits.

There was a problem hiding this comment.
This bumps status.observedGeneration to the current generation even when componentsCollected is false. So on a spec change followed by a failed OIDC discovery, anyone using the standard observedGeneration == generation && Available=True gate sees a stale Available from the previous generation and treats it as current. The per-condition observedGeneration tells the truth, but in practice nobody reads that field.
I think the top-level field should only advance once components have actually been collected, so it means "this generation was fully processed". Something like:
if componentsCollected && cr.Status.ObservedGeneration != cr.Generation {The doc in docs/status-conditions.md says it "reflects the generation the operator had processed", which is what we want it to mean, so this lines the code up with the doc.

Building on the CodeRabbit comment above, it's not just the surplus-replica case. The predicate kubectl rollout status uses for "complete" is four checks: observedGeneration caught up, updatedReplicas == desired, replicas == updatedReplicas, and availableReplicas == updatedReplicas. We only have the first two here. With maxSurge on a 1-replica Deployment you get updatedReplicas=1, replicas=2, availableReplicas=1 (the old pod), and we'd report Available=True, Progressing=False mid-rollout, which is exactly the state we're trying to make visible.
Worth matching all four and adding a table case per clause in api_test.go.

There was a problem hiding this comment.
Not for this PR, but worth a ticket: a bad image tag leaves the Deployment with ProgressDeadlineExceeded forever, and with this logic we'd sit at Progressing=True, Degraded=False indefinitely. ClusterOperator convention would flip Degraded there. The Deployment's own Progressing condition with reason ProgressDeadlineExceeded is the signal to key off. Is there a follow up for this?

There was a problem hiding this comment.
Just want to confirm, ADR-0019 says the CR reports the three rollup conditions "plus per-component conditions". This PR only publishes the rollup. With one component today they're indistinguishable, and adding typed per-component conditions later is additive, so I'm fine with it being a follow-up. Just want to make sure it's tracked and not lost.

Nit: controller-runtime already logs every returned error as "Reconciler error" with the same wrapped message, so this log.Error doubles every failure in the logs. I'd drop it.

Small thing, the PR description says the status is patched but this is Status().Update. Update is fine here since cr was just read and nothing else touches it during the reconcile, so a conflict just means a requeue. Just worth aligning the description, and keep in mind if a second status writer ever shows up, Patch with client.MergeFrom is the safer option.

Nit: the preallocation comment is a lot of words for a slice of two elements, a plain var componentConditions []metav1.Condition reads cleaner and the difference won't ever show up.

What
Implements the status contract for
HyperFleetConfig:status.conditions(
Available,Progressing,Degraded, following the OpenShiftClusterOperator convention per ADR-0019) and
status.observedGeneration,populated by the bundle controller on every reconcile. Previously the CRD
only defined this schema (HYPERFLEET-1406/1407) — nothing ever wrote to it.
Why
Partners and operators need a way to observe HyperFleetConfig's installation
health without reading Deployment internals directly. This closes that gap
and gives
kubectl get hfca meaningfulAVAILABLE/PROGRESSING/DEGRADEDview.
How
internal/component/api/api.go: the API component now derivesAvailable/Progressingfrom the Deployment's live.Status(replicacounts and generation lag), returned via
Component.Conditions().internal/bundle/bundle.go:Component.Conditionsgains anapplied []client.Objectparameter so components can read back live status withouttheir own cluster client —
apply.Objectsalready round-trips it for free.internal/controller/hyperfleetconfig_status.go(new):aggregateStatusrolls up all components' conditions (
Available= AND,Progressing= OR)and derives
Degradedfrom controller-level signals (missing referencedSecrets, or the last reconcile error) via
meta.SetStatusCondition.internal/controller/hyperfleetconfig_controller.go:Reconcilenow usesa named return +
deferto patch status on every exit path, trackingcomponentsCollectedso a reconcile that fails before any componentreports in (e.g. a transient OIDC-discovery blip) doesn't publish a
fabricated healthy
Available/Progressing— those are left at theirlast-recorded value while
Degradedcorrectly flips toTrue.docs/status-conditions.md(new): documents the two condition layers(this operator-layer vocabulary vs. the API's own
Reconciled/LastKnownReconciled/etc.) and the full reason-string table.Progressing,Degraded) on the CRD.Notable design/security decisions
Degraded's message for a reconcile error is a static, safe string — neverthe raw wrapped error — since
status.conditionsis readable by anyonewith
get/liston this cluster-scoped CRD, and some error paths (OIDCdiscovery's SSRF guard) can otherwise leak internal network details. The
full error is still logged server-side (
log.Error(reterr, ...)).HYPERFLEET-1512's AC) is folded into thisstory's
Degradedhandling since 1409's own AC requires testing thatscenario — follow-up: flag 1512 in Jira to close/narrow once this
merges.
