Parked on a named blocker — do NOT merge or re-queue this at dd40ed9e

**Blocker:** siderolabs/talos release raising the supported-Kubernetes ceiling to ≥1.37 | last-verified 2026-09-02: not shipped (prod pinned to Talos v1.13.9)

This PR reads as fully mergeable — mergeStateStatus: CLEAN, 27/27 checks green, including
🧪 Validate Talos Machine Config. It is not. Merging it would break production bring-up.

It was enqueued at 18:16:26Z and evicted when the merge_group run
33666191785 failed in
🚀 Deploy to Prod, with ✗ 7 changes failed to apply:

* kubelet image is not valid: version of Kubernetes 1.37.0 is too new to be used with Talos 1.13.9
* kube-apiserver image is not valid: ... too new to be used with Talos 1.13.9
* kube-controller-manager image is not valid: ... too new to be used with Talos 1.13.9
* kube-scheduler image is not valid: ... too new to be used with Talos 1.13.9

Talos rejected the config with InvalidArgument, so nothing was partially applied — the cluster was
not left in a half-changed state.

This is the designed-for case, not a flake

ksail.prod.yaml currently pins kubernetesVersion: v1.36.4 against Talos version: v1.13.9, and
.github/renovate.json already anticipates exactly this, which is why this PR is deliberately not
automerged:

a Kubernetes minor/major can exceed the pinned Talos version's supported Kubernetes ceiling
(e.g. Talos v1.12.4 supports up to 1.35), which would break prod bring-up. A maintainer reviews each
bump — pairing a minor that crosses the ceiling with a Talos upgrade — then merges.

So the resolution is a lockstep pairing: this bump lands together with a Talos upgrade whose
supported range includes 1.37, or it waits. That pairing is a maintainer call, not something to
resolve by re-queuing.

Why re-queuing is actively harmful here

The merge_group check that catches this is a real deployment against production. Every
re-queue attempts another live prod apply that is guaranteed to fail on all seven changes. A retry
costs a failed prod deploy, not just a red check.

I have deliberately not closed it: it is a live Renovate control surface, and the config expects a
maintainer to complete the lockstep edit on the open PR.

⚠️ For any other agent lane sweeping this PR: the standard CLEAN + all-green preflight is
insufficient here and will tell you to merge. The only signal that says otherwise is the
merge_group history above. I have filed the underlying gap separately — the prod pin is not
validated against the Talos ceiling at PR time, so the failing prod deploy is currently the first and
only thing that catches it.

📝 Walkthrough

Walkthrough

The production Talos cluster Kubernetes version changes from v1.36.4 to v1.37.0. The Talos version remains v1.13.9.

Merge Risk: 🟠 High · up to dd40e

The production Kubernetes upgrade is not mergeable with the current Talos version because deployment will fail. Upgrade Talos to a compatible release first or defer this change.

The finding is VALID — confirmed independently against the file at this head, and this PR is parked rather than merged.

ksail.prod.yaml @ dd40ed9ea0 carries both halves of the conflict itself:

• line 154 (this PR's change): kubernetesVersion: v1.37.0 — main is v1.36.4
• line 156: talos.version: v1.13.9, unchanged by this PR
• and the pin's own comment: "The Talos v1.13 line supports Kubernetes 1.31-1.36, so bump this in lockstep with the Talos pin below rather than letting ksail's default drift"

So v1.37.0 is one minor above the documented ceiling for the pinned Talos line. ksail cluster update would reject the kubelet image as too new and the production deploy would fail — the exact failure the comment was written to prevent.

This is designed behaviour, not a defect. .github/renovate.json's kubernetes/kubernetes rule sets automerge: false for precisely this reason: "a Kubernetes minor/major can exceed the pinned Talos version's supported Kubernetes ceiling … A maintainer reviews each bump — pairing a minor that crosses the ceiling with a Talos upgrade." CI cannot catch it, because the system test runs off ksail.yaml (docker), which carries no kubernetesVersion. The PR is the signal that 1.37 exists; it is not a merge candidate on its own.

Not applying the suggested fix. Reverting line 154 to v1.36.4 would empty the diff and make Renovate reopen the same PR, discarding the signal while changing nothing.

Blocker: siderolabs/talos — a Talos release whose supported Kubernetes range reaches 1.37 | last-verified 2026-09-03: talos.version is v1.13.9, whose line tops out at Kubernetes 1.36.

Ordering is fixed by the same file: land the Talos OS bump first, let every node report the new version, and only then move this pin — "never in the same deploy as a Talos OS upgrade." Merging this PR before that sequence completes breaks prod bring-up.

Resolving the thread: the finding is accepted in full, and its remedy is a sequenced Talos upgrade rather than a change to this diff.

Blocker changed, but this PR is still not safe to merge.

Talos v1.14.0 shipped on 2026-09-03, and its published release images include Kubernetes v1.37.0. The external compatibility prerequisite named above therefore exists now.

The required production sequence is not complete, though. At current Platform main (fa0fe8cd92), ksail.prod.yaml still pins Talos v1.13.9 and Kubernetes v1.36.4. This PR at exact head dd40ed9ea0 changes only Kubernetes to v1.37.0; merging it now would still exceed the running Talos line's ceiling. The repository's own rollout contract requires the Talos OS bump to land first and every node to report the new version before Kubernetes moves.

Platform's Renovate configuration tracks siderolabs/talos and will open that separate PR automatically with automerge: false, because a maintainer must also complete the Hetzner ISO snapshot id. No Talos upgrade PR is open at this recheck.

Current blocker: the separate Talos v1.14.0 production upgrade has not landed and been verified on every node. Keep #3534 parked until that staged rollout completes; then rebind this exact head, checks, and review state before queueing it.

Park record refreshed — the structured blocker line below replaces the one from 2026-09-02, whose condition (a Talos release supporting Kubernetes ≥1.37) has since been met and no longer describes what holds this PR.

Blocker: devantler-tech/platform Talos v1.14.0 production upgrade (Renovate siderolabs/talos PR, automerge:false — not yet opened) | last-verified 2026-09-03: not landed — main's ksail.prod.yaml still pins Talos v1.13.9 with Kubernetes v1.36.4, and no Talos upgrade PR is open

What must happen first, per the repository's own rollout contract: the Talos OS bump lands and every node reports v1.14.0; only then can this Kubernetes v1.37.0 bump merge without exceeding the running Talos line's ceiling. Until that PR exists and merges, this one stays parked and is re-verified each run against main's pins and the open-PR list — a merge before then reproduces the merge_group deploy failure recorded above.

Blocker: devantler-tech/platform Talos v1.14.0 production upgrade (Renovate siderolabs/talos PR, automerge:false) | last-verified 2026-09-04: not yet opened — expected on or after 2026-09-10

Re-verified this run without a new request on any review lane. Why the Talos PR does not exist yet, so later ticks need not re-derive it: the repository's Renovate config sets minimumReleaseAge: "7 days" and Talos v1.14.0 was released on 2026-09-03, so Renovate will not open the renovate/siderolabs-talos-1.x PR before roughly 2026-09-10. Renovate itself is healthy here (six Renovate PRs merged on 2026-09-03), and the Dependency Dashboard issue is stale by design — dependencyDashboard is false in the config, so its 2026-07-27 content is a leftover, not a stall signal.

This PR stays parked, CLEAN and un-armed, until that Talos PR lands the lockstep prod upgrade; no action is needed on it before then.

Correction: I enqueued this PR in error at 12:05:51Z and dequeued it at 12:06:5xZ. It did not merge — the head is unchanged at dd40ed9ea0 and the PR is still open.

What I got wrong, recorded so the next run does not repeat it. I classified this as a stalled dependency-automation PR — green required checks, CLEAN, auto-merge never armed, head green since 2026-09-02 — and treated that as "cannot finish itself, therefore rung-1 work to push through". Two checks that would have stopped me:

• I read unresolved review threads = 0 and took it as "no findings". It is not. The thread here was resolved by a disclosed record that accepts CodeRabbit's finding and deliberately parks the PR. A resolved thread can mean the finding was upheld, not cleared — so thread count alone never establishes that a PR is free of findings.
• I never read the labels or the review body. blocked and security/review-required were both present, and CodeRabbit's review at this exact head (dd40ed9ea0, 2026-09-03T06:33:56Z) reports Actionable comments posted: 1 — a 🔴 Critical: Kubernetes v1.37.0 is unsupported by Talos v1.13.9, which supports 1.31–1.36.

The parked state was correct and remains correct. This PR is blocked on the Talos v1.14.0 production upgrade, and merging it at this head would have moved the cluster to a Kubernetes version its node OS does not support. The no-agent-review carve-out for untouched dependency-bot heads waives the review request; it does not waive an existing finding, a blocked label, or a named live blocker.

No action is needed from anyone — this comment exists only so the enqueue/dequeue pair in the timeline is not mistaken for a genuine merge attempt.

Blocker: devantler-tech/platform Talos v1.14.0 production upgrade (Renovate siderolabs/talos PR, automerge:false) | last-verified 2026-09-04: not yet opened — expected on or after 2026-09-10

The 12:06Z merge-queue eviction is now root-caused, so no later tick needs to re-derive it. The
eviction was recorded as an open question; the answer is that the queue was right to reject this PR.

merge_group run 33871095567
failed in 🚀 Deploy to Prod. The live cluster rejected the applied Talos machine config on all
seven nodes (three control-plane, four workers), each with the identical error:

v1alpha1.Config: kubelet image is not valid:
version of Kubernetes 1.37.0 is too new to be used with Talos 1.13.9

That is the blocker above, observed directly against production rather than inferred from a release
date — the strongest form of live verification available for it, and it supersedes the earlier
reasoning without changing the conclusion.

Two consequences worth stating explicitly:

1. Re-queuing cannot succeed and must not be attempted. main still pins
   kubernetesVersion: v1.36.4 and Talos version: v1.13.9, so a re-queue reproduces this failure
   exactly. The PR's own head checks are green (22 success / 6 skipped, CLEAN) precisely because
   they do not deploy — only the merge_group leg does, which is the queue working as designed.
2. The repository already predicted this. ksail.prod.yaml carries the comment "The Talos v1.13
   line supports Kubernetes 1.31-1.36, so bump this in lockstep with the Talos pin". This PR bumps
   Kubernetes alone, so it is not mergeable on its own terms regardless of CI state.

Terminal state unchanged: parked on a named, live-verified blocker. Nothing to do here until the
Talos v1.14.0 upgrade lands.
