Subject: [PATCH 05/11] fix: stop committed resource controller reconcile storm
(#1089)
setAccepted unconditionally wrote a new AcceptedAt timestamp and a
time-varying StatusSummary on every call, causing a non-empty status
patch even when the CR was already accepted for the current generation.
The self-watch (EnqueueRequestForObject) fired on each patch,
re-enqueuing every accepted cores commitment in a tight ~2s loop and
keeping the workqueue depth permanently elevated around 80.
Add an early-return guard in setAccepted that skips the patch when
Ready=True/Accepted is already set for the current generation.

## Summary
- Add `### History` section to `docs/apis.md` documenting the History
CRD as a scheduling decision audit trail, with relationship to pipelines
noted and added to the mermaid diagram
- Add link to `docs/guides/multicluster/readme.md` from the
documentation landing page
## Test plan
- [ ] Verify markdown renders correctly
- [ ] Confirm History CRD documentation matches actual struct in
`api/v1alpha1/history_types.go`

+History is a cluster-scoped audit trail of scheduling decisions for a given resource (e.g., a Nova instance).

Subject: [PATCH 07/11] fix: reset gauge metrics in reservation monitor to
prevent stale values (#1092)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
## Summary
- Add `Reset()` calls on `numberOfReservations` and `reservedResources`
GaugeVecs before repopulating in `Collect`, preventing stale label
combinations from persisting when reservations are deleted or change
status
- Add context timeout on the Kubernetes List call to prevent scrape
hangs
- Follows the same pattern already used in
`internal/scheduling/reservations/capacity/metrics.go`
## Test plan
- [ ] Verify `make test` passes
- [ ] Verify `make lint` passes
- [ ] Compare with the capacity/metrics.go pattern to confirm
consistency

Subject: [PATCH 08/11] fix: deep-copy capacity map to prevent informer cache
corruption (#1065)
The capacity filter assigned hypervisor Status.Capacity map references
directly into a local working map, then mutated those maps during
free-resource calculations. Since the maps are shared with the
controller-runtime informer cache, each scheduling pass permanently
decremented cached capacity values, progressively starving scheduling
until all hosts appeared full.
Fix: deep-copy the capacity map per hypervisor before subtracting
allocations so the informer cache is never mutated.

# Changelog
+## 2026-07-27 β [#1093](https://github.com/cobaltcore-dev/cortex/pull/1093)
+
+### cortex v0.3.4 (sha-4f44f3b7)
+
+Bug fixes:
+- Deep-copy capacity map to prevent informer cache corruption β the capacity filter assigned hypervisor Status.Capacity map references directly into a local working map, then mutated those maps during free-resource calculations. Since the maps are shared with the controller-runtime informer cache, each scheduling pass permanently decremented cached capacity values, progressively starving scheduling until all hosts appeared full ([#1065](https://github.com/cobaltcore-dev/cortex/pull/1065))
+- Reset gauge metrics in reservation monitor to prevent stale values β adds `Reset()` calls on `numberOfReservations` and `reservedResources` GaugeVecs before repopulating in `Collect`, preventing stale label combinations from persisting when reservations are deleted or change status ([#1092](https://github.com/cobaltcore-dev/cortex/pull/1092))
+- Stop committed resource controller reconcile storm β `setAccepted` unconditionally wrote a new AcceptedAt timestamp and a time-varying StatusSummary on every call, causing a non-empty status patch even when the CR was already accepted. Adds an early-return guard that skips the patch when Ready=True/Accepted is already set for the current generation ([#1089](https://github.com/cobaltcore-dev/cortex/pull/1089))
+
+Non-breaking changes:
+- Add History CRD documentation and multicluster guide link ([#1091](https://github.com/cobaltcore-dev/cortex/pull/1091))
+- Update `github.com/prometheus/client_golang` to v1.24.1 ([#1090](https://github.com/cobaltcore-dev/cortex/pull/1090))
+- Update `k8s.io/api`, `k8s.io/apimachinery`, `k8s.io/client-go` to v0.36.3 ([#1086](https://github.com/cobaltcore-dev/cortex/pull/1086))
+- Update `github.com/sapcc/go-bits` ([#1085](https://github.com/cobaltcore-dev/cortex/pull/1085))
+- Update `kube-prometheus-stack` to 87.19.2 ([#1090](https://github.com/cobaltcore-dev/cortex/pull/1090))
