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.

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: v1.37.0main 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.

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.

Retracted — this comment duplicated the standing park record, and one of its claims was wrong.

I re-derived the Talos/Kubernetes support-matrix blocker from scratch and posted it as a new finding.
It was not new: this PR has carried that blocker since 2026-09-02, it was confirmed against CodeRabbit's
review on 09-03, and the current structured record (09-04T23:13Z) already names the enabling work and
its expected arrival path. Nothing in my comment changed the disposition.

One claim in it was also incorrect: I wrote that auto-merge was "never armed". A run enqueued this PR
in error at 2026-09-04T12:05:51Z and dequeued it, leaving the failed merge_group run at
33871095567. "Green but unarmed" was the wrong mechanism; the PR is parked deliberately.

The authoritative record is the standing blocker line above, not this comment. Re-verify that line
before acting on this PR.

Root cause on my side: I checked open issues for existing tracking before writing, but not this PR's
own comment history. Searching only one of the two surfaces is what let a re-derivation look like a
discovery.

Parked on a named blocker. Do not re-queue until the Talos pin moves.

I enqueued this because every visible gate was clean — 28 green checks, no unresolved threads, a green review at head, no conflict. The merge queue then evicted it, and the cause is real rather than transient:

ksail.prod.yaml: Kubernetes v1.37.0 is not verified compatible with Talos v1.13.9:
version of Kubernetes 1.37.0 is too new to be used with Talos 1.13.9.

So this update cannot merge on its own. It needs a Talos version that supports Kubernetes 1.37, and until that lands, re-queuing only repeats the eviction.

Why it looked ready. The check that governs this change — 🧪 Validate Talos Machine Config — is skipped on the pull request by the path filter, and only runs in the merge group. That is why this sat for days looking merge-ready while being structurally unmergeable, and why no amount of waiting or re-arming would have finished it. Filed separately as #3624, because it affects any update of this shape, not just this one.

No changes pushed to this branch: the fix belongs to the Talos pin, not to this update.

Blocker: #3626 | upstream | last-verified 2026-09-06: Talos pinned at v1.13.9, k8s v1.37.0 rejected

Why the green checks are misleading. This PR reports mergeStateStatus: CLEAN with every PR-level check green, and it still cannot merge. Its head was built 2026-09-02T17:57Z; the Talos/Kubernetes compatibility validator landed 2026-09-04T19:35Z in #3583. The PR's checks therefore predate the guard. The guard runs unconditionally on the merge-group revision, so this PR passes every pre-merge signal and is then evicted by:

ksail.prod.yaml: Kubernetes v1.37.0 is not verified compatible with Talos v1.13.9:
version of Kubernetes 1.37.0 is too new to be used with Talos 1.13.9.
Choose compatible pins; complete any Talos upgrade separately before raising Kubernetes.

That is the guard working as designed, not a flake and not a defect in the talos: path filter — ksail.prod.yaml is correctly listed there.

This has already happened twice today, at 10:00:50Z and again at 13:54:32Z. The second enqueue was mine: I re-queued on a green pentad without first pulling the merge-group history, which is exactly the check that would have shown the first eviction. Recording that so the next dispatch does not repeat it — the PR surface alone cannot tell you this PR is unmergeable.

What actually unblocks it: Talos must move to the v1.14 line first (v1.14.0 went GA 2026-09-03), in its own deploy, with a matching Hetzner ISO id. Then Kubernetes advances one minor, separately — the sequencing ksail.prod.yaml documents in its own comments. #3626 carries that work.

No action is available on this PR itself until #3626 lands. Renovate will keep it current in the meantime.

Disabled auto-merge on this PR. It was armed by app/botantler-1 at 2026-09-07T15:53:01Z, which directly contradicts the park record above.

The park says this PR must not be enqueued, because Talos is pinned at v1.13.9 and rejects Kubernetes v1.37.0. But an armed auto-merge does not read park records — it merges the moment the checks go green. So the two states together meant the park would hold only for as long as 🧪 Validate Talos Machine Config kept failing, and would be silently overridden by anything that turned it green. On this repository merging means deploying to the production cluster from inside the merge queue, so that is not a harmless race.

Re-verified before acting: the blocker #3626 is still open, and ksail.prod.yaml on main still pins the Talos version that rejects this bump. The park is current.

Nothing else about this PR changed — it stays open, parked, and ready to re-arm once the Talos pin moves. That is the step that should re-enable auto-merge, deliberately, rather than a green check doing it by accident.

Correcting the blocker record: the ordering this PR is waiting on cannot happen

Earlier comments here (2026-09-12, 2026-09-16) park this PR behind #3713 with the plan
"#3713 lands first, then this revalidates." That ordering is not achievable, so retrying on
it will keep this PR red indefinitely. Two live checks establish why.

1. #3713 — the Talos bump on its own — is structurally unmergeable. Its current head
a8203d4d fails the same 🧪 Validate Talos Machine Config check, with 8 migration errors:

UnattendedInstallConfig config is incompatible with v1alpha1 config (.machine.install) ·
.machine.nodeAnnotations is already set in v1alpha1 config ·
kubelet config is already set in v1alpha1 config (.machine.kubelet) ·
cluster network config is already set in the v1alpha1 config ·
kube-apiserver config is already set in v1alpha1 config (.cluster.apiServer) ·
kube-controller-manager config is already set in v1alpha1 config ·
cluster proxy config in v1alpha1 config … can't be used with KubeProxyConfig document ·
cluster network config in v1alpha1 config … can't be used with KubeFlannelCNIConfig document

Talos v1.14 stops carrying these settings in v1alpha1, so our existing patches collide with the
new documents the moment the pin moves. The version bump and the 14-file patch migration are
atomic
— there is no order in which they land separately with CI green in between.

2. Talos v1.14 is sufficient for this bump — now proven, not assumed. The compatibility gate
delegates to upstream siderolabs/talos/pkg/machinery/compatibility, so I probed that package
directly (machinery v1.14.0-alpha.2), with a positive control to show the probe discriminates:

Talos pin Kubernetes pin SupportedWith
1.13.9 1.36.4 ✅ supported — positive control
1.13.9 1.37.0 too new to be used with Talos 1.13.9this PR's failure
1.14.0 1.36.4 ✅ supported
1.14.0 1.37.0 supported

So the Kubernetes pin here is fine and needs no change; it simply cannot precede the Talos move.

The real chain

#3534 (this PR) → blocked by → #3850 (atomic Talos v1.14 bump + the 14-file migration,
which supersedes #3713) → blocked by → #3851 (four machine-config fields with no v1.14
document equivalent: kubelet.extraMounts, install.extraKernelArgs + grubUseUKICmdline,
apiServer.extraVolumes, and machine.files/etc/kubernetes/...).

Blocker: #3851 | upstream | last-verified 2026-09-16: open; #3850 blocked on it, #3713 red at a8203d4d with the 8 migration errors above

Nothing in this PR's own diff (a one-line kubernetesVersion bump) needs fixing, and I have not
touched it. It stays parked — but now behind the blocker that can actually clear it.

Note for prioritisation: #3851 now gates a Kubernetes minor-version bump as well as the Talos
migration itself, which raises its value beyond the migration alone.

Blocker record refreshed — #3851 is closed, so the previous line is stale

My earlier record
named #3851 as the live blocker and said it was open. It is now closed — the four
machine-config fields all have decided answers
(decision).
Leaving that line in place would let a later run skip this PR for a reason that no longer exists,
so it is replaced rather than left to age.

The chain is unchanged in shape and one link shorter: this PR still cannot land until the Talos
v1.14 migration lands, because the Talos and Kubernetes bumps are atomiccontracts_test.go
pins setup-talosctl.sh's TALOS_VERSION to ksail.prod.yaml, and Talos 1.13.9 + Kubernetes
1.37.0 is rejected by the compatibility gate (probed directly: 1.13.9+1.36.4 ✅, 1.13.9+1.37.0 ❌,
1.14.0+1.37.0 ✅).

What changed is that #3850 is now implementable — it has a file-by-file plan and 0 open
blockers — rather than waiting on a decision.

Blocker: #3850 | upstream | last-verified 2026-09-16: open and now unblocked (#3851 closed); the Talos v1.14 migration must land first because the Talos and Kubernetes bumps are atomic

Correction: #3850 still has an open dependency

The previous blocker refresh said #3850 was implementable with zero open blockers. That conclusion was wrong.

The live GitHub dependency relation currently records #3850 as blocked by open devantler-tech/ksail#6776. The current #6776 record, refreshed on 2026-09-19, in turn names the Kubernetes 0.36/0.37 compatibility conflict tracked by devantler-tech/ksail#6728: loft-sh/apiserver still has no published revision built against Kubernetes 0.37.

Blocker: #3850 | upstream | last-verified 2026-09-19: OPEN and explicitly blocked by open devantler-tech/ksail#6776; the migration must land before this atomic Talos and Kubernetes bump can proceed

This PR remains correctly parked with auto-merge disabled.

Diagnosed: parked on a named blocker, not a repairable failure

This PR's two red checks are one failure, and no change to this PR can clear it. Recording the diagnosis so it is not re-derived each sweep.

🧪 Validate Talos Machine Config fails with the compatibility guard's own message:

ksail.prod.yaml: Kubernetes v1.37.0 is not verified compatible with Talos v1.13.9:
version of Kubernetes 1.37.0 is too new to be used with Talos 1.13.9.
Choose compatible pins; complete any Talos upgrade separately before raising Kubernetes.

CI - Required Checks is the aggregate of that one job, not a second fault.

The guard is right and the ordering it names is the correct one. Prod runs Talos v1.13.9 (confirmed against the live nodes: all eight report Talos (v1.13.9), and .github/scripts/setup-talosctl.sh pins TALOS_VERSION="1.13.9" to match). Kubernetes 1.37 needs Talos 1.14 under it.

Blocker chain, each link verified live today:

  1. This PR needs Talos 1.14 first — that is chore(deps): update dependency siderolabs/talos to v1.14.0 - abandoned #3713, which is itself red.
  2. chore(deps): update dependency siderolabs/talos to v1.14.0 - abandoned #3713 fails because the machine config still sets fields that Talos 1.14 moved into dedicated documents — eight conflicts, including .cluster.apiServer, .machine.kubelet and .machine.cluster.network. That migration is Migrate the Talos machine config onto the v1.14 configuration documents #3850.
  3. Migrate the Talos machine config onto the v1.14 configuration documents #3850 is gated on Migrate off the removed Talos MachineConfig.Kubelet / ClusterConfig.CoreDNS accessors ksail#6776 (open): prod renders through KSail's pinned pkg/machinery, so the config cannot move to document kinds that renderer does not yet understand, even once talosctl accepts them.

So the order is #6776 → #3850#3713 → this PR. Raising Kubernetes here before Talos moves is exactly what the guard exists to refuse.

Leaving this open and parked rather than closing it: the bump is wanted, just not yet landable. Nothing here needs a fix — re-run it once #3713 is green.

Parked on a named blocker: the Talos upgrade must land first.

🧪 Validate Talos Machine Config fails here for a reason the guard states outright:

ksail.prod.yaml: Kubernetes v1.37.0 is not verified compatible with Talos v1.13.9: version of Kubernetes 1.37.0 is too new to be used with Talos 1.13.9. Choose compatible pins; complete any Talos upgrade separately before raising Kubernetes.

So nothing is wrong with this bump — it is simply ahead of the Talos pin, and no rebase or re-run will clear it. The Talos upgrade it is waiting on (platform#3713, Talos v1.14.0) is itself blocked: v1.14 rejects this repository's machine config with 8 errors, because settings still expressed as legacy v1alpha1 fields now need to be their own configuration documents. That migration is platform#3850, gated in turn by ksail#6776.

Ordering, for whoever picks this up next:

ksail#6776  →  platform#3850  →  platform#3713  →  platform#3534 (this PR)

This PR becomes actionable once platform#3713 merges.

Parked on a named blocker, with the cause read rather than assumed. The failing 🧪 Validate Talos Machine Config check is not a flake and not this bump's own defect. The newer talosctl this PR brings in rejects settings that the repository still carries in the v1alpha1 document, because Talos v1.14 moved them into their own configuration documents:

* kubelet config is already set in v1alpha1 config (.machine.kubelet)
* cluster network config is already set in the v1alpha1 config (.machine.cluster.network)
* kube-apiserver config is already set in v1alpha1 config (.cluster.apiServer)
* kube-controller-manager config is already set in v1alpha1 config (.cluster.controllerManager)
* cluster proxy config ... can't be used with KubeProxyConfig document
* cluster network config ... can't be used with KubeFlannelCNIConfig document

So this bump cannot go green until the machine config is migrated onto the v1.14 documents, which is #3850 — and that migration is itself held by ksail#6776, because production renders through KSail's pinned pkg/machinery, which disagrees with a final talosctl about which document kinds exist. Migrating the config to satisfy CI while production still renders with the pinned machinery would break the render rather than fix it.

Blocker: #3850 | upstream | last-verified 2026-09-21: open, and itself blocked by ksail#6776

No adaptation commit: nothing in this PR's diff can fix a repository-wide config migration, and forcing the validation green here would mean weakening the check that is correctly reporting the problem. Leaving it open so it rebuilds once #3850 lands.

Correction to the parking note above. This PR's current failure (run 35550630448, 01:24Z) is not the talosctl settings rejection. It is the repository's own compatibility guard, and it is working as intended:

ksail.prod.yaml: Kubernetes v1.37.0 is not verified compatible with Talos v1.13.9 … complete any Talos upgrade separately before raising Kubernetes.

So the chain is: this PR waits on the Talos v1.14 upgrade (#3713), which is itself parked on the machine-config migration noted there. There is nothing to fix on this branch; it becomes mergeable once #3713 lands and this rebases.

Blocker chain updated. The note above names a pull request that no longer exists. platform#3713 was closed on 2026-09-22 because Renovate's grouped Talos update, platform#4044, superseded it. The chain is otherwise unchanged. This Kubernetes bump waits on the Talos v1.14 upgrade (now #4044), because the compatibility guard refuses Kubernetes v1.37.0 on Talos v1.13.9. #4044 in turn waits on platform#3850, the migration onto the v1.14 configuration documents, which is still open (re-verified 2026-09-22).
