docs(hack): fix a wrong claim about grep-error propagation in two contract tests (#3620)
<!-- Thank you for making a contribution! Here are some tips for you: - Use Conventional Commits for the PR title: `type(scope): description` - Types: feat, fix, docs, style, refactor, perf, test, build, ci, chore - Scopes are not an exhaustive list — pick the most specific scope for the change and extend the list when a genuinely new area appears. Examples: - System components: dashboard, platform, operator, cilium, kube-ovn, linstor, fluxcd, cluster-api - Managed apps: postgres, mariadb, redis, kafka, clickhouse, virtual-machine, kubernetes - Development and maintenance: api, hack, tests, ci, docs, maintenance - Breaking changes: append `!` after type/scope (`feat(api)!: ...`) or add a `BREAKING CHANGE:` footer - If it's a work in progress, consider creating this PR as a draft. - Don't hesistate to ask for opinion and review in the community chats, even if it's still a draft. - Add the label `backport` if it's a bugfix that needs to be backported to a previous version. --> ## What this PR does `hack/promote-gate-contract.bats` and `hack/release-freeze-contract.bats` both carried the same wrong comment above their `code_lines` helper: it said a real grep error (exit 2) fails a pin through the helper's own exit status, distinct from an empty match (exit 1). That was never actually the mechanism. `code_lines` is always piped into a further `grep` in both files, never the last stage of a pipeline, so ordinary (no `pipefail`) pipe semantics discard whatever it returns on its own, regardless of runner. `hack/cozytest.sh`, the runner these tests actually execute under in CI, also appends a `return 0` to every line that is exactly `}`, `code_lines`' closing brace included, making that exit status even less trustworthy as a signal. What catches a real grep error is the output, and only for one class of pin. The error empties `code_lines`' stream, so a pin that requires something to be present in that stream fails on it. A pin demanding an absence stays blind: an exact count of zero is what an emptied stream produces anyway, and what the pin was written to assert. Both files hold pins of that shape. Nor is the `[ -n "$block" ]` guard at the top of each test the backstop: a block here is a bare awk extraction, upstream of `code_lines`. The new comment says both things and stops there. Comment-only: `code_lines`'s body is untouched in both files, and all tests pass under both `bats` and `hack/cozytest.sh` before and after. Known limitation of the wording: the comment says the top-of-test `[ -n "$block" ]` guard cannot see a filter failure, which is true, but both files also carry non-empty guards on values that did pass through `code_lines` (`promote-gate-contract.bats:72,73,165` and `release-freeze-contract.bats:166,236,327` via `step_line`), and those do fail on an emptied stream. The discriminator is whether the guarded value came through the filter, not where the guard sits in the test. ### Screenshots Not applicable, no UI change. ### Downstream repositories <!-- Cozystack is upstream for repositories that are NOT kept in sync with it automatically, and nothing in CI compares the two sides, so a change here can break them silently. Which change forces what, and which file to touch, is the trigger map in docs/agents/contributing.md under "Downstream Repositories". Walk it before you tick anything. IF YOU ARE AN AI AGENT OR AN LLM, THIS IS PART OF THE TASK, NOT A FORM TO FILL IN: 1. Walk the trigger map against the actual diff of this PR, file by file. Do not decide from the PR title or from your memory of what you changed. 2. For every repository you tick, open the follow-up PR there and link it on the same line. A ticked box with no link claims work that does not exist, which is worse than an empty box. Search that repository for an open PR or issue covering it first, and link that instead of filing a duplicate. 3. When the follow-up is out of scope, or needs a decision that is not yours to make, open an issue in that repository instead, link that, and say so in the PR body. Do not push a speculative PR into another repository just to fill a line here. 4. Do not tick "No downstream repository is affected" to make the checklist go away. If you are unsure, leave every box empty and say so in the PR body, so a human decides. --> - [x] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: ### Release note <!-- Write a release note: - Explain what has changed internally and for users. - Start with the same `type(scope):` prefix as in the PR title - Follow the guidelines at https://github.com/kubernetes/community/blob/master/contributors/guide/release-notes.md. --> ```release-note NONE ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Clarified comments describing how code-line filtering errors are detected. * Documented pipeline status behavior and why output-based assertions are used instead of relying solely on command status codes. * No user-facing behavior or executable logic changed. <!-- end of auto-generated comment: release notes by coderabbit.ai --> |

fix(ci): stop labeled events from cancelling and re-running backports (#3569)
## What this PR does A run joins its concurrency group before any job-level `if` is evaluated, so `prepare`'s guard in `backport.yaml` is too late to help. By the time it works out that a label event is irrelevant, that run has already cancelled whatever was in flight for the same PR. Labels set with the default `GITHUB_TOKEN` start no run, which is why the in-repo labelers never showed this. Third-party GitHub Apps do start runs, and they arrive in bursts. The delivery survived, which is why this went unnoticed for so long. The old guard admitted a run on the PR's cumulative label set, so the last label of a burst, the one nothing cancels, requalified and redid the work. In the bursts on record the kill lands within seconds of the merge run starting, well before the cherry-pick, so the cost was a restart rather than a lost backport, recorded as nothing more than a cancelled run sitting next to a green one. Two changes to the concurrency key, and both are needed. A label event that requests no backport now goes into a group of its own, so it can neither cancel nor displace the run doing the work. A label event that does request one queues behind that run instead of killing it, because `backport` and `backport-previous` are separate requests and both have to finish. Splitting alone would let `backport` cancel the merge-triggered run. Queuing alone would let an unrelated label evict a pending request, since the group holds a single pending run and a newer one replaces it. `prepare`'s condition is scoped in the same commit. It read the PR's cumulative label set, so once a merged PR carried `backport`, any later unrelated label re-entered the job to redo a backport already delivered. That run used to get cancelled by the next label in the burst. After the change above it runs to completion, so the scoping has to land here rather than as a follow-up. The coupling runs the other way too, and it is the sharper half. That redundant run is exactly what redelivered the backport the burst had just killed, so narrowing the guard on its own would convert a noisy delivery into a missing one. Neither change is safe to land without the other. Both jobs also gain a `timeout-minutes` ceiling, which is a consequence of the queuing rather than housekeeping. A cancelling key disposed of a stuck run by killing it; queuing makes the next genuine request wait behind it instead, on the six-hour job default, which turns one wedged job into a six-hour hole in the release line. That ceiling reaches a stuck job and nothing else: a run can also wedge at the run level with every job already finished, and `timeout-minutes` has no run-level equivalent, so nothing in the workflow reaches that state. `docs/release.md` now tells an operator to look for a run still in flight and clear it before re-applying the label, because the retry queues behind it rather than replacing it. The ceiling bounds execution, not the wait for a runner, and thirty minutes is generous rather than calculated. Execution on run 29844315422 was six seconds for `prepare` and two and sixteen for the matrix legs, against 9m24s, 5m28s and 5m45s of runner queue for the same three jobs. That queue is a third unbounded case: GitHub's limits page says "job execution time" for the six-hour job cap while spelling out that the 35-day run cap "includes execution duration, and time spent on waiting and approval", and [orgs/community#50926](https://github.com/orgs/community/discussions/50926) shows a job sitting six hours on "Waiting for a runner to pick up this job" under `timeout-minutes: 5`. So the value is picked to leave room for a cherry-pick far larger than any on record while replacing the six-hour default, and nothing here is sized against the queue, because nothing here can be. This removes a mitigation, and the trade is worth naming on both sides. Under an unconditional cancel a run wedged at the run level cleared itself, because the next event killed whatever was sitting in the group. That is the same behaviour that killed live backports, so the mitigation is inseparable from the bug being fixed: keeping it means keeping label events that cancel a backport in flight. What it buys is a change of failure mode rather than one fewer failure. A backport lost silently, discovered weeks later as a fix missing from a release line, becomes a delay the operator can see in the run list, with the recovery written into `docs/release.md`. There is no lossless alternative here: `queue: max` removes the eviction but only by dropping the conditional cancel entirely, and the group key cannot tell a manual retry from a second genuine request. The run cited above, 31232645133, is still live and retained on purpose: it is the only observed instance of the run-level wedge, so clearing it would remove the evidence for the paragraph that describes it. Its exposure is one pull request, #3262, which carries no backport label, so nothing is queued behind it. The old condition also carried a disjunct that could never decide anything. A `labeled` payload already lists the new label in `pull_request.labels`, so `contains` was true whenever the explicit `github.event.label.name` check was, and the name check only ever agreed with a `contains` that had already matched. The restructure drops it by construction rather than by deletion: the name check is now the whole of what a `labeled` event may match on. ### Why this no longer touches `pull-requests.yaml` `main` fixed it there by splitting the group key, then refined that so a `full-e2e` label stays in the main group instead of publishing a second `E2E Tests` status on one SHA. That is the better mechanism, it neither queues nor delays, and `gate-concurrency-contract.bats` now pins `cancel-in-progress: true` in that file, so what this PR originally did would turn it red. Nothing was left to add there, so the hunk is dropped and its pin with it. The split-key idea is applied in `backport.yaml` instead, where it did not exist. One claim from the earlier description is withdrawn. It said the leftover risk was a duplicate backport PR, opened when the original had merged and its branch had been deleted before the queued run pushed. `main` has since gained a guard that lists closed PRs on the `backport-<n>-to-<target>` branch and skips the target when one of them merged. Branch deletion does not defeat it: `GET /branches/backport-3510-to-release-1.6` is 404 while the same head filter on `/pulls?state=closed` still returns the merged PR. So a redundant run only cost runner minutes, and the scoping above removes the run. ### Screenshots Not applicable, no UI change. ### Downstream repositories Walked the trigger map in `docs/agents/contributing.md` against the diff. The only workflow it cites is `tags.yaml`, for the release-prep behaviour `cozystack/ccp` documents. Every `hack/` trigger it lists either names a specific file another repository mirrors or gates on, or covers moving and renaming under `hack/`. This PR appends tests to a contract file the map does not name, and moves nothing. No package, chart, values file, CRD, image reference, namespace, variant or node prerequisite in the diff. - [x] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: ### Release note ```release-note fix(ci): stop `labeled` pull request events from cancelling the automatic backport run already in flight.

fix(e2e): stop the sandbox cluster CIDR overlapping the pod range (#3750)
## What this PR does The sandbox Talos config and the platform install step both used `10.244.0.0/16`, one as the Kubernetes cluster CIDR and the other as the kube-ovn `POD_CIDR`, so two allocators drew from one range. kube-ovn owns pod IPAM and allocates flat from `POD_CIDR`. Cilium is chained behind it (`generic-veth`, target `kube-ovn`) and allocates no pod addresses at all, but it still carves its own per-node router IP and Ingress IP out of `Node.spec.podCIDR`, which kube-controller-manager slices from the cluster CIDR. Sooner or later kube-ovn hands a pod an address cilium already holds. When that address is the Ingress IP the agent refuses the sandbox with `IP ipv4:<addr> is already in use`, and cilium never relents on it, so the pod proceeds only if something reschedules it onto a different address; in the run this was filed from, the same address was refused seven times across six pod UIDs before the suite ran out of budget. When it is the router IP nothing complains and only host-to-pod traffic breaks. This moves the sandbox cluster CIDR to `100.65.0.0/16`, which no other range in the tree uses, and adds a guard so the two cannot be brought back together by accident. Pod addresses do not change. They still come from kube-ovn out of `10.244.0.0/16`, and cilium does not require a chained endpoint's address to sit inside its own allocation CIDR, so only cilium's two per-node infrastructure addresses move. The quiet variant gets fixed twice over, which is worth spelling out because only half of it was obvious. Under `ipam.mode: kubernetes` cilium also installs a route for the node's own pod CIDR via `cilium_host`. On the current default that route covers `10.244.a.0/24` on a node whose pods actually live behind `ovn0`, so it shadows real pod addresses. Moving the cluster CIDR both stops the router IP from ever being handed to a pod and retargets that route at `100.65.a.0/24`, where it shadows nothing. Excluding the addresses on the kube-ovn side instead is not an option: cilium picks its offsets by random scan over the node's range, so there is no static set to exclude. The collision shows up in two shapes, and both have been seen. Loudly, on the Ingress IP, where the agent names the address in the event, which is the failure https://github.com/cozystack/cozystack/issues/3736 was filed for. Quietly, on the router IP, where the pod comes up and the only symptom is `connection refused` on a kubelet probe, with `ip route get <podIP>` on the node resolving to `local ... dev lo`; that variant is documented in https://github.com/cozystack/cozystack/issues/3445 and https://github.com/cozystack/cozystack/issues/3615. They were being tracked as unrelated flakes in different suites before the shared cause was identified. ## What the guard covers, and what it does not `hack/sandbox-cidr-disjoint.bats` pins the configuration, not the behaviour. It reads the values out of the tree and fails when they overlap. It does not reproduce the collision, which needs a running cluster. It checks the invariant rather than the literals, so either value may move as long as they stay disjoint, and it checks the cluster CIDR against the service and join ranges too, because landing on one of those instead is the next way to get this wrong. An extraction that comes up empty, duplicated or misshapen fails the test instead of shrinking the comparison, and comments and blank lines inside the list are skipped rather than read as the end of it. It is not a YAML parser, though: anything it does not read as a bare dotted quad fails the shape validation rather than being understood, which is the safe direction but not the same promise. Those three are the allocator ranges and nothing more. The sandbox node network, the load-balancer pool and the transit range of a component that is off by default are not read, so the guard is not a complete map of what the cluster CIDR has to avoid. An IPv6 entry fails the shape validation rather than getting an overlap check, so dual-stack means extending the guard rather than passing through it. ## Residual risk I did not prove from source that cilium is the only consumer of `Node.spec.podCIDR` in this topology. What I did check is that kube-proxy is disabled and that `local-ccm` runs the node-lifecycle controller only, with no route controller. This diff selects the full e2e suite, 21 Chainsaw suites with `gateway` and `mongodb` among them, so a consumer I missed surfaces as a red run on this PR rather than staying an assumption. Split of what covers what: the static checks and the unit guard cover the configuration, and the e2e run covers the behaviour. Nothing short of a green suite answers whether cilium's router and Ingress addresses behave once they sit outside the range kube-ovn allocates from. ## A check that is not "the suite went green" `hack/e2e-cilium-endpoint-leak-healer.sh` already prints a line of its own for this exact collision, so there is a signal to read that does not depend on the overall verdict. In the `cozyreport` artifact it lands at `snapshots/<suite>/host/namespaces/kube-system/v1/pod/cilium-leak-healer-*/healer/current.log`, and the lines to grep for are `IP is this node's Cilium ingress IP`. In the run this was filed from there are 42 of them, all naming the same address. After this change that line cannot be produced by an address inside the kube-ovn range, because there is no longer an address that is in both. So the expectation is zero from the first run, not zero on average: one occurrence contradicts the change rather than being noise, and is worth stopping on. A green suite can be green for many reasons; this line disappearing has only one. ## Scope This fixes the sandbox and nothing else. For a real installation the cluster CIDR lives in the operator's own machine configuration, outside this repository, so the same collision is still reachable there. https://github.com/cozystack/cozystack/issues/3740 tracks the product side, including the finding that the install documentation does not merely allow the overlap but instructs operators to create it, by requiring `podCIDR` to match the cluster's pod CIDR. There is a tradeoff in this worth naming rather than leaving to be discovered. Talos defaults `podSubnets` to `10.244.0.0/16` (`DefaultIPv4PodNet`, `pkg/machinery/constants/constants.go:888` at v1.13.6, the version this tree ships), and the platform defaults `networking.podCIDR` to the same value, so an operator who takes both defaults gets the overlap. Until now the sandbox shared that topology and was the one place the bug surfaced where anyone would see it. After this change it no longer reproduces the operator-facing form, and nothing else does either. That is the right call for CI, which should not be wedged by a defect it did not introduce, but it does mean the production exposure loses its only accidental detector. Closes https://github.com/cozystack/cozystack/issues/3736 To be explicit about what closing that issue does and does not mean: this removes the reproduction in the sandbox and leaves the product configuration untouched. The collision is still reachable for users, and https://github.com/cozystack/cozystack/issues/3740 is where that lives. The issue text describes the root mechanism, which is wider than its title, so the closure covers the e2e failure it was filed for and not the platform default. ### Screenshots Not a UI change. ### Downstream repositories No box is ticked deliberately, and no follow-up PR is opened, so a human decides. Walking the trigger map against this diff: both `hack/e2e-prepare-cluster.bats` entries in it are scoped to node prerequisites, the kernel modules a node must load, the containerd settings, the LVM `global_filter` and the cluster domain. This diff changes none of those, it changes a network range, so no entry fires literally. The underlying constraint does reach several of them all the same. `cozystack/talm` sets `podSubnets: [10.244.0.0/16]` in `charts/cozystack/values.yaml`, the same range the platform uses for `networking.podCIDR`, so the documented Talos bootstrap produces the overlap this PR removes from the sandbox. `cozystack/ansible-cozystack` reaches it from the other side: `roles/cozystack/defaults/main.yml` sets `cozystack_pod_cidr: "10.42.0.0/16"` and renders it into `networking.podCIDR`, while its inventories set `cluster-cidr: 10.42.0.0/16`, so those two are identical as well. And `cozystack/website` prescribes the equality outright, `install/kubernetes/generic.md` stating that `podCIDR` and `serviceCIDR` must match the Kubernetes cluster configuration. No issue is filed there yet on purpose: which side moves is not decided, and asking talm to change `podSubnets` would be the wrong request if the platform ends up moving instead.

fix(ci): stop labeled events from cancelling and re-running backports
A run joins its concurrency group before any job-level `if` is evaluated, so `prepare`'s guard cannot stop a label event from disturbing the run already backporting a PR. Labels set with the default GITHUB_TOKEN start no run, but labels set by third-party GitHub Apps do, and they arrive in bursts, so each one cancelled the backport the merge had just started. The delivery survived anyway, which is why this went unnoticed: the old guard admitted a run on the PR's cumulative labels, so the last label of a burst requalified and redid the work. In the bursts on record the kill lands within seconds, well before the cherry-pick, so the cost was a restart rather than a lost backport. Move a label event that requests no backport into a group of its own, and let one that does request a backport queue rather than cancel. Both halves are needed. `backport` and `backport-previous` are separate requests that both have to complete, so they share a group and must not cancel each other, while every other label does no work here and only has to stay out of the way. Scope `prepare` to the labels each trigger is entitled to read at the same time. Reading the cumulative label set on a `labeled` event let any later unrelated label on a merged PR still carrying `backport` re-enter the job to redo a backport already delivered. That redo is also what redelivered a killed backport, so narrowing the guard alone would turn a noisy delivery into a missing one: neither change is safe to land without the other. Bound both jobs with `timeout-minutes` for the same reason, since a queued request now waits on the run ahead of it rather than replacing it. The ceiling bounds execution and not the wait for a runner, which no job-level key reaches, so 30 is generous rather than calculated: every execution measured on this workflow has been seconds, against minutes of queue that nothing here can bound. Document the recovery path the narrowing removes: with no accidental re-run left, re-applying whichever backport label the PR already carries is how an operator retries a merge-triggered run that died.

fix(e2e): stop the sandbox cluster CIDR overlapping the pod range
The sandbox Talos config and the platform install step both used 10.244.0.0/16, one as the Kubernetes cluster CIDR and the other as the kube-ovn POD_CIDR, so two allocators drew from one range. kube-ovn owns pod IPAM and allocates flat from POD_CIDR. Cilium is chained behind it and allocates no pod addresses, but it still carves its own per-node router IP and Ingress IP out of Node.spec.podCIDR, which kube-controller-manager slices from the cluster CIDR. Sooner or later kube-ovn hands a pod an address cilium already holds. When that address is the Ingress IP the agent refuses the sandbox with "IP ipv4:<addr> is already in use", and cilium never relents on it, so the pod only proceeds if something reschedules it onto a different address. In the failure this comes from, the same address was refused seven times across six pod UIDs before the suite ran out of budget. When it is the router IP nothing complains at all and only host-to-pod traffic breaks. Move the cluster CIDR to 100.65.0.0/16, which no other range in the tree uses. That deliberately stops the sandbox matching the layout the install documentation prescribes, so it is not a value to put back. Pod addresses are unaffected: they still come from kube-ovn out of 10.244.0.0/16, and cilium does not require a chained endpoint's address to sit inside its own allocation CIDR. Excluding the addresses on the kube-ovn side would not work, because cilium picks its offsets by random scan over the node's range. The new guard checks the invariant rather than the literals, so either value may move as long as they stay disjoint. It covers the service and join ranges too, since landing on one of those instead is the next way to get this wrong.

feat(clickhouse): let the backup sidecar trust a private S3 CA, unblocking the backup e2e round-trip (#3385)
## What this PR does Gives the ClickHouse `clickhouse-backup` sidecar a way to trust an S3 endpoint whose certificate is signed by a private CA, and uses that to make the ClickHouse backup/restore e2e round-trip actually run in CI. This actualizes #2600, whose feature code and example scripts have since landed on `main` independently, and whose remaining contribution — the e2e test — was still in the retired BATS format. #2600 can be closed once this merges. ### 1. `backup.endpointCA` on the ClickHouse chart The sidecar had **no TLS/CA surface at all**: bucket coordinates and credentials arrive as `S3_*` env, and nothing let it verify an endpoint signed by a private CA. Cozystack's own in-cluster SeaweedFS is exactly that case — it serves `:8333` behind the self-signed "SeaweedFS CA" — so a ClickHouse release could only ever back up to a publicly-trusted endpoint. MariaDB (`storage.s3.tls.caSecretKeyRef`) and Postgres (barman `endpointCA`) have had a CA field all along; this closes the gap for ClickHouse. `backup.endpointCA` takes `{name, key}`. When set, the chart mounts that Secret into the sidecar and points `SSL_CERT_DIR` at it. Empty — the default — renders no env, no mount and no volume, so existing releases are byte-for-byte unchanged. **Why `SSL_CERT_DIR` and not `AWS_CA_BUNDLE`.** Both are honoured by `altinity/clickhouse-backup:2.7.4`; I measured them against a self-signed endpoint and public AWS S3 in turn. Go reads `SSL_CERT_DIR` *in addition to* the system bundle, so both endpoints verify. `AWS_CA_BUNDLE` *replaces* the SDK's trust pool: the private endpoint verifies, and public S3 then fails `x509: certificate signed by unknown authority` — it would silently break a release that also talks to a public endpoint. `S3_DISABLE_CERT_VERIFICATION` was rejected outright, since it drops verification rather than trusting one more CA. ### 2. The e2e suite, and what it was really testing Two Tests added to the existing `hack/e2e-chainsaw/clickhouse/` suite (in name order, mirroring the `etcd`/`mariadb`/`postgres` shape — see the layout rationale below for why they live here rather than in a new directory): - **`clickhouse-1-backup-contracts`** (CI, `tenant-test`, ~98s): a backup-enabled ClickHouse asserted against the *running* cluster — the `clickhouse-backup` sidecar on the `ch-backup-api` `:7171` port, and the `<release>-backup-api-auth` Secret whose keys the sidecar's `API_USERNAME`/`API_PASSWORD` actually resolve `valueFrom`. Each is a silent break if a chart bump renames it. Needs no object store. - **`clickhouse-2-backup-roundtrip`** (CI, `tenant-root`): `Bucket` → `Altinity` strategy + `BackupClass` → source ClickHouse with a sentinel row → `BackupJob` → in-place `RestoreJob` → to-copy `RestoreJob` into a second instance, driving `examples/backups/clickhouse/run-all.sh` so test and docs cannot drift. The round-trip was originally gated behind `CLICKHOUSE_E2E_S3_ROUNDTRIP` and **skipped in CI** — its `PASS (1.01s)` meant the gate fired, not that a backup happened. `backup.endpointCA` removes the reason for the gate, so the suite now adopts the same three preconditions mariadb/postgres rely on: run in `tenant-root` (an isolated tenant's Cilium egress allowlist blocks its Pods from reaching `tenant-root`'s SeaweedFS), target the in-cluster endpoint instead of the `Bucket`'s external ingress URL (an unroutable placeholder in CI), and trust its certificate via the copied CA. It also pre-cleans with `cleanup.sh`, because `tenant-root` is shared and a leftover `Succeeded` `BackupJob` would satisfy the harness's wait without a backup ever running. Both backup Tests live in the existing `hack/e2e-chainsaw/clickhouse/` suite rather than a new suite directory, so no selector mapping is added: `hack/select-e2e.sh` already derives `clickhouse` both from `packages/apps/clickhouse/**` (the `*-application` rule) and from `examples/backups/clickhouse/**` (the harness path), and both paths therefore select the suite that actually runs the harness. That alignment is the reason for the layout — a separate `clickhouse-backup/` directory would have made an edit to the harness select a suite that cannot exercise it. `hack/select-e2e.sh` and `hack/select-install.sh` are otherwise untouched (the only change is a comment recording that invariant), and the existing `backup example harness edit selects its app suite` case in `hack/select-e2e_test.bats` covers the mapping. ### Verification - `helm unittest` — 17 pass, including 5 new `endpointCA` cases: the unset default renders nothing, the env/mount/volume wiring, a custom key still projected as `ca.crt`, composition with `useSystemBucket`, and `backup.enabled=false` renders nothing. - The CA-trust behaviour was measured against the real image, not assumed: without a CA knob the sidecar reports `x509: certificate signed by unknown authority`; with `SSL_CERT_DIR` the handshake succeeds. - `hack/select-e2e_test.bats` (16) and `hack/select-install_test.bats` (17) pass; `select-install.sh --validate` reports graph OK. - `make generate` is idempotent, so the pre-commit job's `git diff --exit-code` stays clean. - The contracts Test passed in CI on earlier runs of this branch. The round-trip only became CI-live with this work, so it still needs a green E2E run before merge — the branch has since been rebased onto current `main` to get one. ### Screenshots Not applicable — no UI changes. ### Downstream repositories Walked the trigger map against the diff, file by file. The load-bearing change is the new `backup.endpointCA` field in `packages/apps/clickhouse/values.yaml` / `values.schema.json`; everything else is `hack/e2e-chainsaw/`, `examples/backups/`, one docs paragraph, and regenerated artifacts, none of which appear in the map. - [ ] No downstream repository is affected by this change - [x] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: https://github.com/cozystack/terraform-provider-cozystack/issues/18 — "add, remove or rename a field in an app's `values.schema.json`" reaches the provider's hand-maintained schema, model and expand/flatten pair, so the new nested object is not surfaced until it is added there. Opened as an issue rather than a PR because the natural moment is alongside that repo's next `api/apps/v1alpha1` pin bump, which is a maintainer call. Not ticked, with reasons rather than silence: **cozystack/website** — the trigger is *adding, renaming or removing a package*, and this adds a field to an existing one. `clickhouse` is already in the website `Makefile`'s app list and its reference page is generated from this package's `README.md`, so the regenerated `backup.endpointCA` rows are carried by the existing release-tag automation with no manual PR. **cozystack/external-apps-example** — vendors `hack/package.mk` and `update-crd.sh`, neither of which this PR touches. **cozystack/ansible-cozystack**, **ccp**, **talm**, **cozyhr**, **cozy-proxy**, **cozystack-telemetry-server**, **examples** — no installer values, `hack/` layout, namespace, variant, node-prerequisite, annotation, label or metric in their trigger rows is touched here. ### Release note ```release-note feat(clickhouse): add `backup.endpointCA` so the clickhouse-backup sidecar can verify an S3 endpoint whose certificate is signed by a private CA, such as Cozystack's in-cluster SeaweedFS. Leave it unset for publicly-trusted endpoints; existing releases are unaffected. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added optional private S3 endpoint CA support for ClickHouse backup/restore sidecars via `backup.endpointCA`, including configurable Secret name and CA bundle key (default `ca.crt`). * Sidecars mount the CA and extend trust while leaving public endpoints unchanged. * **Documentation** * Updated ClickHouse chart docs, operational backup guidance, and backup/restore examples to cover CA setup, overrides, and cleanup. * **Tests** * Added helm-unittest and end-to-end coverage validating CA rendering/mounting behavior and ClickHouse backup/restore workflows. <!-- end of auto-generated comment: release notes by coderabbit.ai --> |

chore(codeowners): keep architects as owners in every non-governance rule (#3738)
## What this PR does CODEOWNERS applies only the **last** matching rule, and matching is not additive: a scoped rule fully replaces the `*` catch-all instead of extending it. As a result `@kvaps` and `@lllamnyp` were not code owners for most scoped paths (21 and 36 of the 76 owner-bearing rules, respectively), and several paths (`/hack/`, `/.github/`, `/Makefile`, `/.pre-commit-config.yaml`, `/docs/`) were owned by exactly two people — with "Require review from Code Owners" enforced on `main`, a PR authored by one of them could only be approved by the other. This PR: - appends `@kvaps` and `@lllamnyp` to every rule that lists owners, keeping existing owners and their order; the governance block deliberately stays with `@tym83 @kvaps`, and the ownerless rules for generated files stay ownerless; - spells out the non-additive last-match semantics in the file header; - adds `hack/codeowners-invariant.bats` (auto-discovered by `make bats-unit-tests`), so a future scoped rule that omits the catch-all owners fails unit tests instead of silently carving its path out from under them. ### Screenshots Not a UI change. ### Downstream repositories - [x] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: ### Release note ```release-note chore(codeowners): @kvaps and @lllamnyp are now code owners for every path except governance files, removing single-approver review bottlenecks; a unit test guards the invariant ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Chores** * Updated code ownership rules across dashboards, packages, Kubernetes components, backups, GPU and SeaweedFS components, Keycloak, documentation, and CI files. * Expanded area-specific review ownership while preserving existing governance and API review assignments. * **Tests** * Added automated validation to ensure ownership rules include the required default reviewers. <!-- end of auto-generated comment: release notes by coderabbit.ai --> |

docs(hack): fix a wrong claim about grep-error propagation in two contract tests
Both hack/promote-gate-contract.bats and hack/release-freeze-contract.bats carried the same code_lines helper with the same wrong comment: it claimed a real grep error fails the pin through the helper's own exit status. code_lines is never the last stage of a pipeline in either file, so ordinary (non-pipefail) pipe semantics discard whatever it returns on its own, and hack/cozytest.sh's translator appends a return 0 to every line that is exactly }, code_lines' closing brace included, making that exit status even less trustworthy as a signal. What catches a real grep error is the output, and only for one class of pin. The error empties code_lines' stream, so a pin that requires something to be present in that stream fails on it. A pin demanding an absence stays blind: an exact count of zero is what an emptied stream produces anyway, and what the pin was written to assert. Both files hold pins of that shape. The per-test [ -n "$block" ] guard is not the backstop either. In these two files a block is a bare awk extraction, upstream of code_lines, so that guard cannot see the filter fail; the comment now says so, because reading it as the backstop gets the direction exactly wrong.

fix(e2e): budget each linstor wait separately in post-install-prep (#3715)
## What this PR does Both waits in `hack/e2e-post-install-prep.sh` ran off one 15-minute deadline anchored at the script's start, so the head of the chain ate the window and the tail got whatever was left. Two runs on 2026-08-09 failed that way. The linstor HelmRelease went Ready 452s in, and the Deployment needed a further ~520s because its DB migration lost the apiserver and retried four times. Neither figure passes 900s alone. Their sum does, and the install reported the Deployment as broken. Each wait now gets its own budget, started when the previous link finished. Same shape as the node wait and the MetalLB CRD wait further down the same file. What it buys is that every link gets its whole allowance regardless of what the links ahead of it spent. The cost is on both sides and I measured it. Worst case goes from one 15m window to 900 + 900 + 300 + 300 = 40m, against the 180m the e2e job carries. A Deployment that never converges is now reported at 1355s instead of 900s, from the 452s above plus the loop's 5s poll. A HelmRelease that never goes Ready is still reported at 900s, which I checked by running the new suite against the pre-change script. The timeout now dumps the pods and recent events of `cozy-linstor`. The same "Deployment not Available" has come from a crash-looping migration init container and from a pod waiting on a client TLS Secret cert-manager had not issued yet, and telling those apart used to need the run's bundle. Events come from `kubectl events`, which sorts by last-seen and carries no `--sort-by` to fail on a key some item lacks. Both reads keep their stderr and are bounded, with the client budget smaller than the outer one so kubectl gets to say why before the kill lands. `hack/post-install-prep.bats` runs the script end to end against a stub PATH with a virtual clock, so a 15-minute budget elapses in a few hundred forks and the timings are exact. Four of its six tests fail against the pre-change script. The other two guard the bound that stays. ### Known gaps in the new tests Dropping the `2>&1` from either diagnostic read leaves all six tests green, because the harness catches the script's own stderr into the same file the assertion reads. The property holds in production anyway, since the caller merges both streams into one log, but nothing catches the removal. The test for "one failing read does not suppress the other" needs the pods read to run first; swap the two reads and it passes vacuously. Its comment says so at the point where someone would make that change. ### Screenshots Not a UI change. ### Downstream repositories - [x] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: Walked the map against the diff.

fix(e2e): budget each linstor wait separately in post-install-prep
The post-install prep script waits out a serial reconcile chain -- the linstor HelmRelease, then the linstor-controller Deployment -- against a single 15-minute deadline anchored at the script's start. The head of the chain therefore eats the window and the tail inherits whatever remains, so an install fails whenever the chain merely runs long rather than never converging. Measured on one such failure: the HelmRelease went Ready 452s in, and the Deployment needed a further ~520s because the controller's DB migration lost its apiserver connection and retried four times before succeeding. Neither figure exceeds 900s on its own; only their sum did, and the install reported the Deployment as though it were broken. Give each wait its own budget, started when the link before it completed -- the shape the LINSTOR node and MetalLB CRD waits further down already have. What that buys is not speed but a guarantee: every link gets its whole allowance regardless of what the links ahead of it spent, so the tail can no longer be failed by the head being slow. It is a trade, and the other half is worth stating. The script's worst case becomes 900 + 900 + 300 + 300 = 40m against the 180m the job carries, where before the two waits shared one 15m window. And a link that is genuinely stuck is reported later rather than sooner: a Deployment that never converges surfaces at 1355s where the shared window surfaced it at 900s, on that run's timings. A HelmRelease that never becomes Ready surfaces at the same moment as before, since its budget still starts with the script. A timeout now also lists the linstor pods and the namespace events. The description names the object waited on, not the link that held it up, and the same "Deployment not Available" has been reached both with the controller pod crash-looping its migration init container and with that pod blocked on a client TLS Secret cert-manager had not issued yet. Telling those apart previously required the run's bundle. The events come from `kubectl events` rather than `kubectl get events`. It orders by when an event was last seen, so a condition repeating for minutes -- what a stuck mount looks like -- stays inside the window instead of being pushed out by newer one-off events, and it carries no --sort-by, so it cannot fail the whole read the way a sort key does when one item lacks it. Both reads keep their stderr and carry a bound. A read that fails silently is indistinguishable from a namespace with nothing to report, which is the distinction being drawn; and the caller is blocked in `wait`, so an unbounded read against a wedged apiserver would hold the install open until the job's own timeout. The client budget is strictly the smaller of the two so kubectl gets to name the reason before the outer kill takes it away. The wait helper is named for linstor because those diagnostics read one namespace unconditionally: the wait is generic over its kubectl arguments, what it dumps on the way out is not. The new unit test runs the script end to end against a stub PATH carrying a virtual clock, so a 15-minute budget elapses in a few hundred forks and the timings are exact rather than wall-clock approximate.

fix(ci): decide E2E coverage per changed path
The full-suite escalation for a changed package that reaches no suite was
read off the merged selection, so it depended on the whole diff rather
than on the path that needed it. Any other changed path contributing a
suite name made the selection non-empty and the escalation vanished with
nothing in the output to record it: edit a platform component, adjust the
Chainsaw test beside it, and the component ran that single suite instead
of everything. Over one values.yaml per package under
packages/{apps,system,extra}, 82 of the 159 escalate on their own and
stop escalating once an unrelated suite edit joins the diff.
Coverage is now decided per changed path. Each path resolves through its
owning sources to the suites that exist, and a path reaching none of them
forces the full run whatever the rest of the diff selected. The unit is
the path rather than the source: system/postgres-operator belongs to two
PackageSources where one reaches no suite, so deciding per source would
escalate on that half and run everything for every change to it.
The escalation names its cause on stderr, as every other escalation in
this script already does. Most packages reach no suite of their own, so
this is the branch a full run usually takes; without a line saying which
sources bought it, "why did this run everything" has no answer in the log.
The walk moves into resolve_suites() to be called once per path. POSIX sh
has no `local`, so the function writes into the caller's scope and is
safe only inside the $( ) its single call site wraps it in; a test pins
that the call count stays one.
Two entries leave src_to_suites. `postgres-application` restated what
stripping the suffix produces and `external-dns` restated what carrying
the source name through produces, so both made the exception list read as
longer than the set of real exceptions.

fix(ci): map E2E suites from sources not named after an app
src_to_suites() covered PackageSource names ending in -application plus external-dns, and the filter after the graph walk dropped every other source it reached. cozystack.kuberture and cozystack.securitygroup- controller are neither, so both were walked to and then discarded: a CNI change ran neither of the two controller suites most likely to regress from it, and a change to either package reached no suite at all and escalated to the full run instead of selecting the one that covers it. Every reached source now maps through the table. That table is the inverse of select-install.sh's suite_to_source(), and a test walks every suite through both, so the next source name fitting neither convention fails there rather than quietly making its own suite unreachable. The cilium test measured the gap rather than hid it, asserting the 19 suites the selector could reach and naming the two it could not. The subtraction is removed rather than inverted: kept as an exclusion list it would stay green if the walk stopped reaching them for an unrelated reason. What replaces it is a second assertion against a tree holding one suite the graph reaches and one no source names, which an escalation cannot satisfy.

feat(kubernetes): route tenant worker image pulls through a registry mirror (#3575)
## What this PR does Refs #3513. It addresses one variant of that flake and does not close it; see "Scope against #3513" below. ### Root cause of the variant this addresses The chainsaw `kubernetes-latest` / `kubernetes-previous` suites fail with `node-join failed: fewer than 2 tenant nodes Ready within 18m` and zero registered tenant nodes. The in-guest Talos capture on #3548 shows where the time goes on one class of those runs: the worker loops trying to pull `ghcr.io/siderolabs/kubelet` from public ghcr.io and fails with `Head "https://ghcr.io/v2/siderolabs/kubelet/manifests/...": net/http: TLS handshake timeout host=ghcr.io`. The Talos `kubelet` service never starts (`kubelet was not registered`), so the node never registers, cilium-operator stays `Pending` for lack of a node to schedule on, and the budget expires. On those runs the tenant apiserver is healthy and the worker VMs boot with kube-ovn IPs, so the failing link is the worker's public image-pull egress, and the worker machine config has no `machine.registries.mirrors`, so there is no way to route around it. Same class as the Talos OS image, which #3231 solved with the `talos.imageFactoryURL` cache. The thread also carries a later analysis putting worker-VM CPU starvation from nested-virt oversubscription at the root, with serial-console RCU stalls showing the guest never reaching Talos userland, and reading the TLS-handshake variant as a symptom of the same contention. Nothing here contradicts that. Removing a live dependency on public egress from worker bring-up is worth doing on its own terms, and if the contention account is the dominant one, this narrows what is left to explain rather than competing with it. ### The change **Chart (`packages/apps/kubernetes`, `packages/apps/kubernetes-nodes`)**, a `talos.registryMirrors` passthrough, a map of upstream registry host to `{ endpoints: [ ... ] }`, rendered into `machine.registries.mirrors` of the worker `TalosConfigTemplate` that the MachineDeployment clones from, so it applies at first boot rather than after it. Empty by default: with the default values the rendered chart is byte-identical to main, both content-hash object names included, so no existing worker rolls. This is the durable half; an air-gapped, rate-limited or flaky-egress environment can point worker image pulls at its own mirror, which is the `machine.registries.mirrors` knob the Talos rollover left unfilled. Talos still falls back to the upstream registry unless a host also sets `skipFallback`, so a mirror on its own is not air-gap enforcement, and the field doc says so. The value lands inside the reconcile Job's unquoted heredoc, so it is escaped for backslash, dollar and backtick and renders as a literal. `talos.installerRepository`, `talos.schematicID` and the Talos version render into that same heredoc one block above it and now get the same treatment, so the file is consistent about it rather than escaping only the newest field. Escaping the rendered value covers every byte by construction, which enumerating known-bad shapes does not. The chain is a no-op for values carrying none of those characters, so the default render, content-hash Job name included, is unchanged and no existing worker is replaced. **e2e harness**, an in-sandbox `registry:2` pull-through cache for ghcr.io (`hack/e2e-ghcr-mirror.yaml`), applied at install time from its own step, with `hack/e2e-chainsaw/_lib/ghcr-mirror.sh` setting `spec.talos.registryMirrors` on the tenant CR when the mirror is up and its egress allow is in place, and emitting nothing otherwise so workers pull directly. A `CiliumClusterwideNetworkPolicy` opens one tightly-scoped hole for worker VM (`kubevirt.io: virt-launcher`) Pods in `tenant-test` to reach the mirror, mirroring the existing `talos-image-cache` policy. Two properties of the helper worth calling out, because both are easy to get wrong and both are now pinned by tests. A failed API call is never cached: the decision is reused by every later suite in the shared sandbox, so caching one blip would disable the mirror for the whole run. Readiness is decided once and acted on once. `rollout status` is the cheap way to learn it, but it also exits non-zero on a broken watch, so when it fails the Deployment's own `Available` condition is read rather than the watch's exit code taken as the answer. Exactly one failure is cached, a definite `Available=False`, and that is a trade rather than an invariant: it avoids re-paying the wait in every later suite, and costs a mirror that recovers mid-run. On a node-join failure the suite dumps the mirror's state alongside the Talos image cache it already dumped. Workers being pointed at the mirror and then joining does not establish that the mirror served anything, because Talos falls back to public ghcr.io on its own; the registry's access log is what separates the two, so the dump counts kubelet-image requests across the whole log rather than tailing it. The readiness probe writes an access line every five seconds, so by the time a run has spent its 18m budget a fixed tail window is hundreds of lines short of the request worth finding. ### Testing - `helm unittest packages/apps/kubernetes`, 205 tests, 22 suites; `helm unittest packages/apps/kubernetes-nodes`, 14 tests, 4 suites. New cases: the default omits `machine.registries.mirrors`, and a set value renders it with the endpoint. - `hack/ghcr-mirror_test.bats`, 23 tests. Beyond the manifest's two-phase split, egress identities, pull-through config and the pure YAML builder, this covers every outcome of `resolve_ghcr_mirror_endpoint` against a stubbed `kubectl`: an API NotFound caches, a transient query failure does not, a shell reporting a missing binary is not mistaken for either, a failed egress allow does not cache and its reason reaches the log, a rollout watch that failed for a reason the API does not confirm does not cache while a definite `Available=False` does, and a committed endpoint is cached and short-circuits the next call. The stub honours `--tail`, so the diagnostic's tests tell a filtered read from a truncated one instead of trusting the flag, and it reports errors on stderr as the real binary does. The suite also pins that the install step excludes the Cilium policy from its pre-Cilium apply, not only what that exclusion produces. - `hack/talos-reconcile-heredoc_test.bats`, 5 tests, which render both charts and run the heredoc through a real shell with hostile values rather than regexing the rendered string. A `matchRegex` cannot catch a heredoc the shell refuses to emit; this runs it. - `hack/run-kubernetes-talos-spec_test.bats`, 5 tests over `talos_spec_block`, the point where the two optional fragments are merged. The assertions splice the result under `spec:` and read it back with yq, so a block indented into the wrong parent fails instead of passing. - `packages/apps/kubernetes-nodes/tests/render-parity.sh` byte-identical; per-chart `make generate` in both charts with no drift; both `cozyrds` `openAPISchema` blocks equal to their `values.schema.json`. - The pinned `mirror.gcr.io/library/registry:2.8.3@sha256:a3d8aaa6...` is the digest Docker Hub serves for that tag, and `mirror.gcr.io` serves the same OCI index with a linux/amd64 manifest. Run under exactly the security context the Deployment sets, non-root 65532, read-only root filesystem, all capabilities dropped, writable state only on the mounted volumes, it starts, answers `/v2/` with 200, and serves `ghcr.io/siderolabs/kubelet` manifests and blobs as an anonymous pull-through. - `shellcheck` and `git diff --check` clean on the new and edited shell. ### What a CI run still has to answer Two runtime facts the harness half rests on, both recorded in the manifest: 1. Talos honours a plain-http mirror endpoint via `machine.registries.mirrors[ghcr.io].endpoints=[http://...]`. If a scheme or TLS knob is additionally needed, `machine.registries.config` has to be added too. 2. The containerd pull from inside the worker VM leaves with the virt-launcher Pod's own Cilium identity, which is what the policy selects. The label half is settled: `run-kubernetes.sh` already reads tenant worker Pods by `kubevirt.io=virt-launcher`, but whether the in-guest pull is subject to that Pod's egress policy at all is not. The second one bounds how strong a claim the harness can make. The gate is a `rollout status` plus an accepted egress-allow object, and neither observes the tenant-side datapath, so the fallback paths cannot make CI worse while the committed path is only as safe as that assumption. The in-repo comments say this rather than claiming the mirror can only ever help. ### Named improvements left out A tenant-scoped reachability probe, like the byte-level 206 check `talos-image-cache.sh` runs from a Pod carrying the consumer's own label, is what turns assumption 2 from an assertion into a measurement, and would also let the suite assert the mirror served the kubelet pull instead of the worker quietly falling back. Left out because a probe that does not exercise the tenant network path would pass while real workers stayed blocked, and the one that does is a change of its own size. The same gap has a cheaper edge: both the install step and the resolver key on the Deployment alone, so an apply that made the Deployment but not the Service still reads as success. That one costs little in practice, since the guest gets a fast NXDOMAIN instead of a dropped SYN, but the gate does check less than it commits to. `registryMirrors` could be a typed `map[string]struct{ endpoints []string }`, the way `nodeGroups` already is in this chart, so malformed input is rejected at admission instead of failing late inside Talos. The helm-unittest escape cases assert the `$` path; the backtick path is covered by the execution-level heredoc bats and the pure-backslash path by the escape chain's construction, so the security contract is fully exercised across the two layers. A backtick assertion at the helm-unittest layer would express it at the fast layer too. The escape chain is spelled out at five interpolation sites across the two reconcile-Job templates. A named helper (an `include` template) would make the escape a single reusable primitive and shrink the surface where the heredoc invariant can be forgotten; the current per-site form is correct and covered, so this is a readability refactor rather than a fix. Only `machine.registries.mirrors` is passed through. `machine.registries.config` is not, so a mirror behind a private CA or one needing credentials still has no knob, and the platform-wide `registries` value does not reach tenant workers. The chart's breaking-change note says so, and also says which knob covers which artifact: the mirror routes registry pulls, while the worker OS disk image arrives as a raw HTTP artifact under `talos.imageFactoryURL` and no registry mirror can touch it. The helper's failure model is worth revisiting as a whole rather than per call site. Every call it makes to the cluster has three outcomes (the world says no, the world says yes, the call could not be made) and a shell exit code carries two, so the third is re-derived at each site from a different signal: stderr text for a NotFound, a field value for readiness, the returned message for a failed apply. Since the resulting decision is cached for the whole sandbox, a misclassification is permanent for the run rather than a blip, which makes each of those sites load-bearing. A single prober answering `yes`/`no`/`unknown`, with the caching rule stated once over that answer, would move the question out of the branches; the current shape reaches the same behaviour but re-establishes it five times. Left out here because it is a visible rework of code this PR only extends, and it would need its own verification of every site; tracked in #3682. One nicety left in the same helper: the diagnostic reads the mirror log twice, once with `--tail=-1` to count kubelet-image requests across the whole log and once with `--tail=50 --prefix` for a bounded context tail. The second read exists for `--prefix`, which attributes each line to its pod; collapsing to one read drops that. The attribution is worthless while the mirror is a single replica and load-bearing the moment it is not, in the one artifact read after a failure, and the second read is itself wall-clock bounded, so it is left in place. ### Merge-order dependency (resolved) #3676 landed first and this branch is rebased onto it. `ghcr_mirror_diagnose` now runs in the node-join failure block under the same phase gate as its neighbours, and each of its reads is wall-clock bounded by the same `COZY_DIAG_READ_TIMEOUT`/`COZY_DIAG_READ_GRACE` the block validates, so no single read can hold the op open. It is placed after the guest captures and before the image-cache re-probe: the console evidence is irreplaceable and must not be starved of budget, and the dump is still cheaper than the Pod-creating re-probe, so the spend order puts it between the two. When the diagnostics phase runs out of budget the dump is declined out loud instead of attempted. An ungated dump would spend that time anyway and take it from the captures behind it, while the mirror's state is partly recoverable from the reads that already ran, so gating costs less than it saves. The known cost is #3686: cheap reads ahead of the gate can drain the whole budget on a viscous apiserver, and the dump is then declined in exactly the runs where the mirror is a suspect. That is a defect of the budget, not of this dump, and it is tracked there. ### Scope against #3513 #3513 asks for three things: capture the guest side, act on the evidence, and do not raise the 18m budget again. The capture landed in #3548 and this consumes its output; the budget is untouched. What this acts on is the TLS-handshake variant only. The same thread documents runs that issue no apid CSR at all inside the whole budget, time lost before Talos reaches the kubelet image, which no registry mirror can affect. So #3513 stays open after this merges, and a green suite afterwards is not evidence the flake is closed. The manifest header says so too, for whoever reads it next. ### Both tenant suites are covered `kubernetes-previous` selects the previous Kubernetes *minor* out of `packages/apps/kubernetes/files/versions.yaml`, `run_kubernetes_test 'keys | sort_by(.) | .[-2]'`, not a previously-released chart. Both suites build their tenant CR from the same in-tree chart through the same helper, so both get the mirror. ### Screenshots Not applicable; no UI changes. ### Downstream repositories Walking the trigger map in `docs/agents/contributing.md` against the diff: **cozystack/terraform-provider-cozystack is affected**. The provider is hand-written, and the map lists "add, remove or rename a field in an app's `values.schema.json`" and "change a default in an app's `values.yaml`" as triggers for its schema, model and expand/flatten pair. This adds `talos.registryMirrors` with a `{}` default to both the `kubernetes` and `kubernetes-nodes` schemas. No other repository matches a trigger. The website's managed-app reference pages regenerate from each package's `README.md` on a stable tag, and this only changes an existing package's README. I have not opened the provider follow-up and have not ticked the box, because a ticked box with no link claims work that does not exist. Leaving it to a maintainer to decide whether the provider models this field and who files it. - [ ] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: ### Release note ```release-note feat(kubernetes): add `talos.registryMirrors` to route tenant worker node image pulls through a registry mirror for air-gapped or flaky-egress environments ``` |

fix(e2e): wire the ghcr.io mirror into the tenant install and node-join flow
Deploy the pull-through mirror from its own install step rather than folding it into the Talos image-cache step, whose early return on a missing values key would otherwise skip it silently. Build the tenant CR spec.talos block from both the OS image cache and the registry mirror, each included only when its in-sandbox backend is up. On a node-join failure dump the mirror's state alongside the Talos image cache, under the same phase gate as its neighbours so it cannot starve the guest captures of budget. Record the mirror's legs in the step's budget inventory. talos_spec_block is covered by a bats suite over all four mirror-up and mirror-down combinations, splicing the result under spec: and reading it back with yq so a block indented into the wrong parent fails, and the install step is pinned to exclude the Cilium policy from its pre-Cilium apply.

fix(e2e): harden the ghcr.io mirror resolver and bound its diagnostics
resolve_ghcr_mirror_endpoint decides once, for the whole shared sandbox, whether tenant workers are pointed at the in-sandbox mirror, so a misclassified transient failure would disable it for the rest of the run. Cache only stable answers: a genuine API NotFound and a definite Available=False; never a transient query error, a missing kubectl, or a failed egress-allow apply. Read readiness from the Deployment's own Available condition when the rollout watch exits non-zero, and commit the endpoint only once the egress allow is in place, surfacing the apply failure reason rather than a generic blip. The node-join diagnostic counts kubelet-image requests across the whole access log rather than a fixed tail, and every read it makes is wall-clock bounded by the caller's COZY_DIAG_READ_TIMEOUT so no single read can hold the failure path open. The bats suite exercises every resolver branch and the diagnostic's filtering, with a kubectl stub that reports errors on stderr as the real binary does and a timeout mock so the bounded reads stay reachable under test.

fix(kubernetes): escape tenant values in the worker reconcile heredoc
The worker TalosConfigTemplate is applied from an unquoted `cat <<EOF | kubectl apply` heredoc, so every free-form value interpolated into it is subject to shell parameter expansion and command substitution at Job runtime. Escape backslash, dollar and backtick on talosVersion, installerRepository, schematicID and the registryMirrors block so each renders as a literal, and record the invariant above the data block in both charts: a new free-form field here must be escaped or render-time pattern-validated, or it reopens command injection into a host-cluster Pod. Escaping covers every byte by construction; the chain is a no-op for ordinary values, so the default render and its content-hash Job name are unchanged. Tests render both charts and run the heredoc through a real shell with hostile values, which a rendered-string regex cannot do, and the default-omits-mirrors assertion selects the Job by kind rather than by document index so it cannot pass against the wrong document.

test(e2e): capture host-netns address attribution and a healthy-pod reference
The collector characterises the host->local-pod route for an affected pod through ovn0 alone, so when a pod IP turns out to be a local address of the host netns instead, nothing records which interface actually holds it. The host netns capture now also takes `ip -o addr show` across every interface and `ip route show table local`, so the owner can be named on the next occurrence rather than only ruled out on ovn0. The collector also inspects NotReady pods only, so a run has no same-window baseline for what a normal route and conntrack state look like on the same node. The per-pod capture becomes a reusable function and runs a second time against one Ready, Running, non-hostNetwork pod on that node, into the same file, so the comparison is in front of whoever opens it. hostNetwork is excluded because such a pod's podIP IS the node's own address and would show the same local-route fingerprint as the fault for an entirely ordinary reason. That baseline depends on the node and nothing else -- the candidates are the rows of the one snapshot the affected set was computed from, and a pod reporting Ready there is by definition not one this run is investigating -- so it is captured once per node and folded into each affected pod's file from a cache. Several affected pods on one node is what a wedged host->local-pod datapath looks like rather than an edge case, and capturing the same healthy pod once per affected pod would spend the caller's envelope re-asking a question already answered -- the cost the node-global dedup and the lookup memo beside it exist to avoid. This adds no read of its own. The cluster-wide pod list gains one column instead of being asked a second time, and that single read's status is what lets the artifact separate a node with no eligible pod from a list that never answered: one line for both would make an unchecked baseline read as an established absence. The two host-netns additions are best-effort execs, like the captures they sit beside. The new row filter carries the field count its jsonpath emits, so a list cut mid-record cannot hand over a fragment as the pod every reading of the affected one is compared against. The unit suite pins these on what they are rather than on what they leave behind. Both host-netns captures are asserted through the kubectl argv the collector issues, container included, because the section headers are separate echoes that outlive the exec being removed. The baseline is pinned from both sides: several affected pods on one node share a single capture, and an affected pod is served the healthy pod from its own node rather than from whichever node the walk reached first. The pod list's column order is asserted against the positions its readers index, because every runtime test answers that list from a stub written by hand and none of them can observe the jsonpath at all.

feat(kubernetes): route tenant worker image pulls through a registry mirror
Add a talos.registryMirrors passthrough to the kubernetes and kubernetes-nodes
charts that renders into the worker TalosConfigTemplate machine.registries.mirrors,
so an operator can point a registry such as ghcr.io at an in-cluster pull-through
mirror and a worker boot no longer depends on live public egress. Default {}
keeps the rendered worker reconcile Job byte-identical to before, content-hash
Job name included. Free-form mirror values are shell-escaped for the unquoted
apply heredoc, covered by an execution-level bats test.
Also add the e2e ghcr-mirror (registry:2 pull-through plus a Cilium egress
policy) and wire it into the kubernetes chainsaw suites, so CI exercises the
mirror path and takes the flaky public ghcr.io kubelet-image pull off live
egress.
Refs #3513 (addresses the egress variant of the tenant-worker node-join
failures; the dominant variant is CI-runner CPU starvation, tracked in the
issue).

fix(e2e): keep a failed mirror lookup from pinning the public factory
resolve_talos_image_factory_url asked whether the in-cluster Talos image mirror exists with a plain `kubectl get deploy`, where a connection refused, an Unauthorized and a real absence all arrive as the same non-zero exit. It then cached that reading for the whole suite, so one unlucky moment sent every tenant worker to the public Image Factory over live egress -- the dependency the mirror exists to remove -- while the run still looked ordinary. Ask with --ignore-not-found -o name instead: a real absence answers exit 0 with no output, which leaves a non-zero exit meaning only that the question failed, and re-ask a couple of times before giving up. Only the empty answer turns the suite toward the public factory. An unanswered lookup warns, falls back for its own caller alone, and is not written to the decision file, so the next tenant test asks again rather than inheriting a guess. Each attempt is bounded twice, and the two bounds are deliberately not equal. kubectl defaults --request-timeout to 0, so a connection that establishes and then stalls has no deadline of its own; the flag alone is not a wall-clock bound either, because kubectl retries discovery several times before giving up. Measured against a stub apiserver, the three ways this call fails behave differently: a refused port answers in under a second and names the refusal, one that stalls mid-TLS gets kubectl's own handshake deadline and still produces text, and a blackholed address produces nothing until some deadline expires. With both bounds at the same value the expiry that arrives first is always the wall-clock kill, so --request-timeout can never fire and that last case stays silent. The wrapper therefore sits ten seconds above it: the request deadline ends the attempt and kubectl says why, and the wrapper remains the backstop for a client that overruns its own deadline. Where timeout is not installed the read runs unwrapped rather than through it: its exit 127 would otherwise count as an attempt that did not answer, three times over, and a missing local binary would pin the whole suite to the public factory while every message blamed the apiserver. kubectl's stderr is left alone, because it is the only thing separating refused from unauthorized from stalled. It is still not guaranteed, since a kill can land before the client has said anything, so the lookup also names the last attempt's exit status before giving up, in the vocabulary the diagnostic reads use for 124 and 137. The diagnostic path asks the same question and keeps its own answer to it. That one gives up after a single attempt, under a phase budget where re-asking spends what the snapshot behind it needs; this one runs on the happy path, where a re-ask costs a suite nothing and buys it the mirror.

test(e2e): pin that an unanswered mirror lookup is not a mirror absence
The Talos image factory decision asks the apiserver once whether the in-cluster mirror Deployment exists, reads any non-zero exit as an absence, and caches that answer for the whole suite. A refused, throttled or timed-out lookup therefore sends every tenant worker in the run to the public Image Factory over live egress -- the dependency the mirror exists to remove -- and the run reads as ordinary environment noise rather than as a decision that was never actually made. Route that question through one helper and pin what the helper owes its caller: the three outcomes it must tell apart, the flags that make the three-way answer possible at all, a deadline on every attempt, the caching rule -- a real absence is resolved once and cached, an unanswered lookup falls back for its own caller alone -- and that a missing local timeout binary leaves the lookup asking the apiserver rather than answering unknown three times over. Two of those need saying carefully, because both concern what the caller is told when the lookup fails. A killed attempt gets its own case, driven by a wrapper that exits without running kubectl at all, so the lookup has to account for why it gave up rather than relay someone else's words: pinning the reason on a kubectl that failed loudly, as the sibling case does, pins it only where it was never in doubt. And the wall-clock bound is pinned as strictly greater than the request deadline beside it, which is the property that lets kubectl reach its own deadline and say what happened; level with it, the kill always lands first. The helper is a placeholder in this commit and claims present unconditionally, so the cases that need the distinction fail. The stubs are files on PATH rather than shell functions because the lookup runs under an external timeout binary, which execs a real file and would never see a shell override. xtrace stays off for the rest of a test that captures stderr: turned back on, a failing assertion wedges bats instead of reporting it.

fix(e2e): bound the tenant failure diagnostics per read and as a phase (#3676)
<!-- Thank you for making a contribution! Here are some tips for you: - Use Conventional Commits for the PR title: `type(scope): description` - Types: feat, fix, docs, style, refactor, perf, test, build, ci, chore - Scopes are not an exhaustive list — pick the most specific scope for the change and extend the list when a genuinely new area appears. Examples: - System components: dashboard, platform, operator, cilium, kube-ovn, linstor, fluxcd, cluster-api - Managed apps: postgres, mariadb, redis, kafka, clickhouse, virtual-machine, kubernetes - Development and maintenance: api, hack, tests, ci, docs, maintenance - Breaking changes: append `!` after type/scope (`feat(api)!: ...`) or add a `BREAKING CHANGE:` footer - If it's a work in progress, consider creating this PR as a draft. - Don't hesistate to ask for opinion and review in the community chats, even if it's still a draft. - Add the label `backport` if it's a bugfix that needs to be backported to a previous version. --> ## What this PR does The node-join failure diagnostics in `hack/e2e-chainsaw/_lib/run-kubernetes.sh` issued about a dozen `kubectl` reads with neither an outer wall-clock bound nor `--request-timeout`, starting with a `describe nodes` through the tenant kubeconfig. That read targets the component least likely to answer in a node-join failure. An unbounded read there does not lose only itself: it holds the Chainsaw op until the op is killed, so everything scheduled after it is lost rather than truncated, the tenant crust-gather snapshot above all. Every read now carries the per-call bound the newer collectors on this path already use. A read that fails or is cut off says so instead of passing in silence, and says only what was observed, because a read that did not finish is silence about the cluster rather than a finding about it. The CDI importer walk gains a cap, and its listing is read on its own so a listing that never answered cannot read as a namespace with no importer in it. Per-read bounds alone do not end the phase, and the collectors here can together spend more than what is left of the op by the time they run. So the phase is bounded as a phase: once its budget is spent, the collectors that have not started are declined out loud. That is not a worst case and is not written as one, but it stops the snapshot being queued behind work begun past the deadline, which is how the snapshot was being lost. The op ceiling is unchanged, since a larger ceiling multiplied by a sum that grows with every collector added is the same problem one collector later. Because what runs last is what gets declined, the block is reordered so the cheap reads come first. The CSR list and the signer log are the discriminator for the failure mode a follow-up fix has to target, and behind two minute-scale collectors they were exactly what a tight run would drop. Adjacent work on the same failure path, all of it in service of the same requirement: - the sibling scheduling-gate branch ends in the same exit and depends on the same snapshot, so its two reads are bounded too; - `talos_image_cache_diagnose` gets its reads bounded and its gate gets `--ignore-not-found`, because `kubectl get` exits 1 for a refused connection or Unauthorized as readily as for NotFound, so a call that never reached the apiserver was being announced as a mirror that was never deployed; - the four numeric knobs are validated rather than only documented, since a suffix or a leading zero on the budget reached the arithmetic in the block's first statement and unwound the whole function before its own headline, leaving a failing run with no diagnostics at all. Comments carry invariants rather than arithmetic. A comment that states a sum has to be kept true forever in every copy of it, and any edit to the code or the order falsifies one of them. The numbers live in the code as values and in the guard that pins them. Relates to #3656. ### Known gaps, deliberately not closed here Some collectors on this path carry no wall-clock bound at all. The image-cache reachability re-probe makes seven unbounded management-cluster calls, and the guest-Talos capture walks its VMI rows uncapped with applies and waits bounded only by `--request-timeout`, which bounds one HTTP request rather than a client retrying against a wedged apiserver. The phase budget stops them being started late; it does not stop one running long once admitted. They are pre-existing and tracked in #3666. Bounding the re-probe in particular would change when the same function gives up on the happy path, and so which image factory tenant workers use, which is not a diagnostic's decision to make. Named improvements left for later, none of them regressions introduced here: - the phase deadline is stamped at block entry rather than against what is left of the op, so a long bringup still narrows the room the derivation assumes; - `bringup` and `largest` are literals in the guard, so a collector heavier than today's will not move them, and the margin is small by design; - the integer-knob validator now exists in four places in this tree, and a shared `_lib` file sourced ahead of both libraries would collapse two of them; - the per-request bound equals the wall-clock bound, so both deadlines fire together and which of the two notes appears is a race; - the ordered list in the chainsaw comments omits the ungated wedge check, which runs first; - section letters no longer sort after the reorder, and the comment-to-code ratio in the touched block is high. ### Testing `hack/run-kubernetes-node-join_test.bats` is new: 22 cases driving the block with a `kubectl` stub that hangs, refuses and answers in part, and a `timeout` stub that fails any read not wrapped in the bounding idiom. It pins that no read escapes a bound, that a cut-off read is named rather than reported as an empty cluster, that the walk cap reports both counts, that a failed listing is not reported as no importers, that the phase declines the rest out loud, that a malformed knob falls back and says so, that the block returns zero so the caller keeps its `exit 1`, and the source order that keeps the discriminating reads ahead of the expensive collectors. Every one was checked by mutation against the unfixed shape. ### Screenshots <!-- REQUIRED for UI changes: attach screenshots or screen recordings demonstrating the visual impact of your changes. PRs with UI changes without screenshots will not be merged. --> ### Downstream repositories <!-- Cozystack is upstream for repositories that are NOT kept in sync with it automatically, and nothing in CI compares the two sides, so a change here can break them silently.

A ticked box with no link claims work that does not exist, which is worse than an empty box. Search that repository for an open PR or issue covering it first, and link that instead of filing a duplicate. 3. When the follow-up is out of scope, or needs a decision that is not yours to make, open an issue in that repository instead, link that, and say so in the PR body. Do not push a speculative PR into another repository just to fill a line here. 4. Do not tick "No downstream repository is affected" to make the checklist go away.

Examples: - System components: dashboard, platform, operator, cilium, kube-ovn, linstor, fluxcd, cluster-api - Managed apps: postgres, mariadb, redis, kafka, clickhouse, virtual-machine, kubernetes - Development and maintenance: api, hack, tests, ci, docs, maintenance - Breaking changes: append `!` after type/scope (`feat(api)!: ...`) or add a `BREAKING CHANGE:` footer - If it's a work in progress, consider creating this PR as a draft. - Don't hesistate to ask for opinion and review in the community chats, even if it's still a draft. - Add the label `backport` if it's a bugfix that needs to be backported to a previous version. --> ## What this PR does Five things in the e2e tooling said something the code no longer does, or did not say it at all. All five are prose; no executable line changes. `docs/agents/e2e-testing.md` section 8 described two of the three on-failure capture legs. The missing one is `hack/e2e-capture-dataplane.sh`, the only leg that reads forwarding state off the node rather than object state, and the only one whose two callers bound it differently, 600s from the BATS runner and 300s from the Chainsaw catch. That split is what decides whether something added to it fits, so a contributor who reads the document and not the script sizes a change against the wrong budget. Its notes contract is described with the carve-out the script declares itself: the two EndpointSlice reads in the LoadBalancer path report nothing either way, so a `<none>` backend line there is the one place a reader still cannot tell an endpointless Service from a read that never answered. The same section said the runner's captures serve "the BATS tests" in two places. They serve the e2e ones. The runner keys on an `e2e-` prefix, on the suite's own filename or on its parent directory, because all three legs read cluster state and a unit runner has `kubectl` on PATH with no cluster behind it. The legs are not gated alike either, so the sentence says which fired where: two key on `kubectl`, and the snapshot leg keys on `crust-gather` being installed, which on a unit runner it usually is not. Two numbers in the capture-gate rationale in `hack/cozytest.sh` no longer described the code. The snapshot leg's cost was given as 360s, the deadline passed to `timeout`; the leg is invoked as `timeout -k 30 360`, so the trap waits out 390s, which is what the comment forty lines below and the op-budget arithmetic in `.chainsaw.yaml` already said. And the data-plane leg was still described as having no bound on its first pod list, and billed at the full 600s on that basis, after that read was given a 28s ceiling. Two files enumerated the BATS suites and both stopped one short. The global catch in `hack/e2e-chainsaw/.chainsaw.yaml` said the runner it names as its analog "only covers the BATS install/openapi tests", and `hack/e2e-chainsaw/README.md` named the same two files. Both miss `hack/e2e-prepare-cluster.bats`, which `packages/core/testing/Makefile` drives through that runner, and which is the suite whose failures leave the sandbox in the state hardest to reconstruct afterwards. `docs/agents/e2e-testing.md` already listed all three, so the tree disagreed with itself depending on which file you opened. A comment in `hack/e2e-install-cozystack.bats` pointed at `hack/e2e-apps/run-kubernetes.sh`, which does not exist; that directory holds two monitoring suites and no runner. The readiness gate it means is the `rollout status` wait in `hack/e2e-chainsaw/_lib/talos-image-cache.sh`, along with both fallbacks to the public factory. relates to #3626 and #3642 ### Screenshots <!-- REQUIRED for UI changes: attach screenshots or screen recordings demonstrating the visual impact of your changes.

docs(e2e): make the op-budget comment name what it guarantees
The 50m ceiling on the kubernetes-* script ops is justified by a comment enumerating what the failure path can spend, and the enumeration was both incomplete and reassuring in the wrong direction. It listed some collectors, said nothing about the node-join diagnostics or the image-cache diagnosis, carried a figure for the guest Talos capture that was half its real cost, and closed by asking the reader to keep the op above the sum, which no ceiling can do because the sum runs past what is left of the op on its own. It now names the phase budget as the thing that keeps the snapshot reachable and lists the collectors this ceiling covers, in the order the phase spends it. It states no sums and no per-collector figures. Why the budget is that number is derived once, beside the budget, and pointed at from here: a figure repeated across three files is a figure that drifts, and the drift is what the reader trusts. It also says what the ceiling does not promise. The budget bounds when a collector may start rather than when the phase ends; several collectors on this path carry no wall-clock bound at all; and the bringup's own waits already exceed this op on ceilings before a single diagnostic runs. So no worst case is claimed, because none can be stated while that holds. Assisted-By: Claude <noreply@anthropic.com> Signed-off-by: Aleksei Sviridkin <f@lex.la> |

fix(e2e): bound the tenant failure diagnostics per read and as a phase
The node-join diagnostics issued about a dozen kubectl reads with neither an outer wall-clock bound nor --request-timeout, starting with a describe nodes through the tenant kubeconfig. That read targets the component least likely to answer in a node-join failure, and an unbounded read there does not lose only itself: it holds the Chainsaw op until the op is killed, so everything after it is lost rather than truncated, the tenant crust-gather snapshot the failing exit triggers above all. Each read now carries the per-call bound the newer collectors on this path already use, sized lower because this block issues a dozen back to back where those bound one. A read that fails or is cut off says so instead of passing in silence, and says only what was observed: a read that did not finish is silence about the cluster, not a finding about it. The importer walk gains a cap for the same reason its listing is now read on its own, since a listing that never answered must not read as a namespace with no importer in it. Per-read bounds alone do not end the phase, and the collectors here can together spend more than what is left of the op by the time they run. Much of that is not ceiling-bounded at all: on the guest-Talos path the applies, waits and deletes carry --request-timeout or --timeout, which bound one HTTP request rather than a client retrying against a wedged apiserver. So the phase is bounded as a phase. Once its budget is spent the collectors that have not started are declined out loud. That is not a worst case and is not written as one, but it does stop the snapshot being queued behind work begun past the deadline, which is how the snapshot was being lost. Raising the op ceiling was the alternative and it is not one: a larger ceiling times a sum that grows with every collector added is the same problem later. Because what runs last is what gets declined, the block is reordered so the cheap reads come first. The CSR list and the signer log are the discriminator for the failure mode a follow-up fix has to target; behind a serial-console walk and a guest-Talos capture that can spend the whole budget between them, they were exactly what a tight run would drop. The comments carry invariants rather than arithmetic. A comment that states a sum has to be kept true forever in every copy of it, and any edit to the code or the order falsifies one of them. The numbers live in the code as values and in the guard that pins them; the prose keeps why the budget comes from an inequality, why admission gates the start rather than the finish, why the cheap reads run first, and which residuals the guard's literals do not cover. The sibling scheduling-gate branch ends in the same exit and depends on the same snapshot, so its two reads are bounded too. So are the reads in the talos-image-cache diagnosis, whose gate also gains --ignore-not-found: exit 1 from kubectl get means a refused connection or Unauthorized as readily as NotFound, and reading it as absent announced the mirror as never deployed on the strength of a call that never reached the apiserver. Bounding those dumps needed a note of its own first, since timeout prints nothing when it fires and a cut-off dump would otherwise leave a bare section header that reads as a cache with no Pod, no Service and no EndpointSlice. The knobs those bounds come from are validated rather than only documented. Each is pasted somewhere that takes digits and nothing else, and each failed differently and quietly: a suffixed or leading-zero budget reached the arithmetic in the block's first statement and unwound the whole function before its own headline, so a failing run produced no diagnostics at all; a suffixed read bound became a millisecond request timeout and made every note blame the cluster for a value; zero disabled the bound outright; a suffixed importer cap made the comparison exit non-zero, so the cap stopped existing; and a non-numeric grace makes timeout exit before running the command at all. A rejected value falls back and says so, which is what the rest of this tree does with its own knobs. All four are re-checked where they are used, since a value set after sourcing never passed the assignment, and the read bound is checked again before the per-request string is composed from it so the two halves cannot disagree. Each default is declared once as a constant, and the re-checks read the bare variable so an unset knob is named rather than silently defaulted. When timeout itself is absent the reads run unbounded rather than being bounded with a binary that is not there: the latter turns every read into an exit 127 and every note into the cluster refusing, and collects nothing, where unbounded is what this path did before any of this. The phase says so once, and says what it costs rather than reassuring. The reachability re-probe in the image-cache helper stays unbounded and its comment names all seven of the calls it makes, the fire-and-forget delete after the probe Pod included: the same function decides the mirror on the happy path, so changing when it gives up is not a diagnostic's decision to make. Its bounds are spelled at each call site rather than precomputed, since a prefix built at source time cannot follow a knob a test lowers afterwards while the --request-timeout beside it does.

test(release): clean up the guard test's scratch dir without an EXIT trap
The freeze-contract suite gained a test that shelves its scratch directory with an EXIT trap. The per-file trap guard added since then reports the file as holding an undeclared trap, so the aggregate unit target fails on a clean tree. Cleaning up on the last line of the test body is what the rest of the converted suites do, and it keeps the failure behaviour the guard exists for: a test that fails leaves its scratch directory behind for inspection, because the cleanup is never reached.

ci(backport): skip a target whose backport already merged (#3616)
<!-- Thank you for making a contribution! Here are some tips for you: - Use Conventional Commits for the PR title: `type(scope): description` - Types: feat, fix, docs, style, refactor, perf, test, build, ci, chore - Scopes are not an exhaustive list — pick the most specific scope for the change and extend the list when a genuinely new area appears. Examples: - System components: dashboard, platform, operator, cilium, kube-ovn, linstor, fluxcd, cluster-api - Managed apps: postgres, mariadb, redis, kafka, clickhouse, virtual-machine, kubernetes - Development and maintenance: api, hack, tests, ci, docs, maintenance - Breaking changes: append `!` after type/scope (`feat(api)!: ...`) or add a `BREAKING CHANGE:` footer - If it's a work in progress, consider creating this PR as a draft. - Don't hesistate to ask for opinion and review in the community chats, even if it's still a draft. - Add the label `backport` if it's a bugfix that needs to be backported to a previous version. --> ## What this PR does Adds a guard step to the `backport` job in `.github/workflows/backport.yaml` that looks up whether a merged pull request already exists on a target's deterministic backport branch (`backport-<pr>-to-<target>`) and skips the checkout and the backport-action step for that leg when one does. A second label event on a PR whose first backport already merged, for example `backport-previous` added shortly after `backport` merged, re-enters this job for the already-delivered target, and cherry-picking the same commits onto a branch that already has them produces an empty pick, which git still reports with a non-zero exit code. Under the `draft_commit_conflicts` setting this workflow already passes to the action, that non-zero exit is read as a real conflict, and the action's attempt to commit the (empty) working tree fails too, surfacing as a "Backport failed" comment on the original PR, for a branch the change has been on for a while. Relates to #3588, which has the full mechanism and a reproduction. The guard only treats a target as done when a PR on that branch actually merged, so a real retry after someone manually closed a conflicting, unmerged backport PR still runs normally; both cases are covered by the new tests. This workflow triggers on `pull_request_target`, which, like `workflow_run`, executes the workflow definition from the PR's base branch (the default branch for the PRs this fires on), not from the PR head, for the same fork-isolation reason. That means this guard only takes effect once this PR merges to `main`; a `labeled` event on an in-flight PR before that still runs whatever version of `backport.yaml` is currently on `main`. The empty-cherry-pick-reported-as-conflict behavior itself lives in `korthout/backport-action` and stays out of scope here; issue #3588 links the upstream report. ### Screenshots Not applicable, no UI change. ### Downstream repositories <!-- Cozystack is upstream for repositories that are NOT kept in sync with it automatically, and nothing in CI compares the two sides, so a change here can break them silently.

-->
## What this PR does
Six fixes to the e2e host->pod data-plane collector and the two call
sites that invoke it, all of one class: a diagnostic that states a fact
it never observed. Every one of them makes a failed run look healthier
than it was, which is the worst direction for a tool that only ever runs
on an already-failed test.
- A list cut mid-record parsed as a valid record. Three `awk -F'|'` row
filters selected by field value and never checked the field count, so an
IP cut mid-octet still looked like an IP and a cut inside a nodeName
still looked like a scheduled pod. The capture then probed an address
the cluster never had and opened a per-node file for a node that does
not exist. Each jsonpath emits a fixed field count per record, so a
shorter row is a fragment by construction.
- Five distinct paths ran zero probes and all reported "reachable,
skipped": no node to probe from, a Service with no port, a probe node
with no `kube-ovn-cni` pod, a host netns with no `nc`/`curl`/`wget`, and
an exec that could not run. An image without a probe client alone would
stamp every LoadBalancer in the cluster reachable and skip the whole
heavy capture. They now report unprobed, each with a reason the run can
actually support.
- Both EndpointSlice reads discarded stderr and were read by emptiness
alone, so a refused read wrote the same `<none>` a Service with no
endpoints writes. They now carry their status. That change armed a
landmine the silence had hidden: the target port was read with
`{.items[0]...}`, and client-go's `evalArray` has no `allowMissingKeys`
escape, so an endpoint-less Service is a hard error rather than an empty
answer. The read now asks with `{.items[*]...}`.
- `pod_on_node` turns its node argument into `--field-selector
spec.nodeName=<node>`, so an empty node asks for pods whose nodeName is
empty, i.e. unscheduled ones. Both tcpdump legs could hand a pending pod
to a capture stamped ANNOUNCER or ENDPOINT. Each leg is now guarded and
says in the artifact that it was skipped.
- Both callers wrapped the collector in a wall-clock backstop and
discarded the result, while the previous-logs leg beside each of them
reports "INCOMPLETE (exit N)". A truncated `dataplane/` directory was
indistinguishable from a complete one that found little.
- The file's own header credited one caller where two exist, under
different backstops (600s and 300s), so a change sized against the named
one can overrun the omitted one.
Diagnostics only. No retries, no cluster mutation, no change to any
test's pass/fail outcome: the statuses that are now read are used to
print a line and nothing else.
Every behavioural change is pinned by a test in the existing bats
surface, verified red against the committed tree before the fix. The two
suites run 53 and 5 tests.
Known limits and deliberate omissions, named so the next reader does not
have to rediscover them:
- A field count cannot catch a cut inside a record's LAST field, since
every separator has already arrived. The comment on the first filter
says so and says where it lands for each of the three. The MetalLB
speaker loop is left without a count for the same reason: its records
carry two fields, and `speaker-1|nod` is indistinguishable from a
genuinely short node name, so a count there would reject nothing while
reading as a closed gap.
- The backstop lines report any non-zero status as `INCOMPLETE (exit
N)`. Exit 127 (no `timeout` on PATH) means nothing ran, so "kept what
landed" overstates it. Left alone deliberately: the same wording ships
on the previous-logs and crust-gather legs beside them, and splitting
only the two new ones would create the asymmetry this PR exists to
remove. All four want the same treatment together.
- When a probe's cni-server lookup fails once and then succeeds while no
probe client is present, the reason line names the lookup for all three
attempts. The named cause did occur, so nothing false reaches the
artifact, but it is narrower than what happened.
- `hack/capture-dataplane.bats` now needs `yq` for one test, and unlike
three sibling suites it does not declare that at the top of the file.
The fan-out caps are sized in units of work while the backstops are
wall-clock, and the worst case exceeds both by multiples. That predates
this branch and is unchanged by it, but the new INCOMPLETE line is what
will make it visible in an artifact for the first time. Tracked
separately in #3671.

fix(ci): close the silent-green gaps in e2e selection and the helm unit sweep (#3670)
## What this PR does Four fixes in e2e test selection and the helm unit sweep. Relates to #3650 #3652 #3655 #3646. select-e2e built both dependency indexes as `$(build_owners_index | sort -u)`, so it read sort's exit status and never yq's (#3650). A broken yq left the index empty, every path fell through to escalation, and CI ran the full suite on every PR. The output was identical to "no owners matched", so it looked like the conservatism the selector is supposed to apply. The suite list one line up had the same shape and a worse result. `$(find ... | sed | sort)` reports sort, never find, and errors went to /dev/null. Every escalation prints that list, so a failed find made "escalate to the full suite" emit a blank line, which both e2e lanes read as "skip Chainsaw" before posting `E2E Tests` green. The outcome that means run everything delivered a run of nothing. find is not the only way to get an empty list, and the escalations are not its only reader, so the check sits where the list is built. The `examples/backups/<app>/` rule escalates nothing and still membership-tests against that list: with it empty, an edit to a backup harness that should run its suite reports nothing to run, on a path no escalation-side guard would ever see. An empty list is a broken enumeration, so the script refuses to answer at all. Both lanes run the step under `bash -e`, so the non-zero exit fails the job. I checked both workflows: neither overrides `shell:`, both capture the selector as a plain assignment. Fourteen tests used `[ "$(echo "$output" | wc -w)" -gt 5 ]` to mean "everything was selected" (#3652). There are 21 suites, so that passes on any six, and partial escalation stayed green. They compare against the whole list now, derived the way the script's own full-suite branch derives it. Drop one suite from that branch and thirteen of them go red. All thirteen passed under the threshold. The fourteenth is the cilium case, and equality shows it was never a full-suite path at all. It resolves through the dependency graph, which reaches 19 of the 21 suites. The two it misses are kuberture and securitygroup, whose sources are not `*-application`, and the mapping covers only those plus external-dns by name. Both controllers declare `cozystack.networking`, so a CNI change that breaks either one runs neither suite. That gap is #3665. The test is renamed for what it measures and pins the 19, so closing #3665 turns it red at the right moment. Editing `hack/e2e-chainsaw/backup/chainsaw-test.yaml.disabled` selected the full suite (#3655). The suffix was ignored when deriving the suite name, the intersection against existing suites emptied, and the empty-selection safety net escalated. A disabled suite runs nowhere, so its edits are the one file class that cannot regress a test, and they were buying the most expensive outcome the selector has. The selector now has a fourth outcome, a failed step rather than a selection, so the contract enumerations in the script header, in `docs/agents/e2e-testing.md` and in both workflow comments say so. The helm unit sweep never visited `packages/tests` (#3646). cozy-lib-tests, the whole test coverage for a helper library that 34 charts consume by symlink, ran only because `packages/library/cozy-lib/Makefile` delegates its `test` target to it. Remove that one line and the suite goes from one execution to zero with the sweep still exiting 0 and still printing "All Helm unit tests passed". Every check the sweep makes runs inside a directory the loop already reached, so a package that never enters the loop takes all of them with it, and what is left is `tests_found`, which counts suites across the whole run rather than per package. The directory is on the list now: 76 executed suites become 77, at 0.1s to 0.3s over six runs against a sweep of roughly 31 seconds. The delegation stays for `make -C packages/library/cozy-lib test` ergonomics, so the suite runs twice. Neither run is load-bearing alone. ### Testing `hack/select-e2e_test.bats` goes from 27 tests to 32, `hack/helm-unit-tests.bats` is new. Each commit is green on its own: 27, 30, 32, 32. The new tests stub the failing component and assert the exit status plus the line naming what broke: a broken yq, a broken find, an empty suite list across all three diff classes, the disabled-suite path, and a guard that the disabled rule drops only that path and not the rest of the diff. The yq test asserts exit 0 on purpose. A missing dependency graph still has a correct answer, the full suite, and a missing suite list does not. Pinning both halves keeps the header and the docs from drifting into claiming otherwise. Two suites fail on my macOS box and fail identically at `origin/main`, so neither comes from this branch: `hack/migration-seaweedfs-db-adopt.bats`, where a container running as the host UID cannot write the bind-mounted temp dir under Colima, and `hack/seaweedfs-naming-audit.bats`, which I confirmed red at the merge base but did not dig into. Every other `hack/*.bats` was run individually and is green. `make unit-tests` stops at the first failing file and both of those sort ahead of `select-e2e_test.bats`, so on macOS the suites this PR touches have to be run directly. ### Named improvements, not done here - The `.disabled` rule keys on the file rather than the parked directory, so it is both wider and narrower than the property it wants. A support file under `hack/e2e-chainsaw/backup/` still buys a full run, and a `.disabled` file dropped inside a live suite directory now selects nothing where it used to select that suite. The property covering both is one level up: a suite directory holding no live `chainsaw-test.yaml` is inert, testable with the same `grep -Fxq` membership check the `examples/backups/*/*` arm already uses. It is not a free win, since a half-written suite directory escalates today and would then select nothing. A cheaper half step is narrowing the glob to `hack/e2e-chainsaw/*/chainsaw-test.yaml*.disabled`, because case globs cross `/` and the shipped pattern also matches nested paths. - `packages/tests/**` is not classified by the selector and reaches the full suite through the unclassified fall-through instead of a rule. Tracked in #3667. - `full_suite_list()` in the bats file cannot fail. cozytest.sh's awk rewrites a lone `}` into `return 0; }`, so a broken find inside the helper would return an empty expected set instead of a red test. Nothing false can pass today, because the script hard-fails on an empty suite list before any assert runs, but that helper is what every equality assert measures against. - The yq check runs before the changed-file list is read, so with a broken graph even a docs-only diff escalates. Measured: a broken yq plus a `docs/x.md` diff returns 21 suites at head against 0 at the merge base. Only reachable in an already broken state, but the graph is consulted at the component lookup and in the closure walk, so moving the check to first use would charge nothing to docs, dashboards and inert-meta diffs. ### Screenshots No UI changes. ### Downstream repositories Walked the trigger map in `docs/agents/contributing.md` file by file against the diff: four files under `hack/`, one under `docs/agents/`, and comments in the two e2e workflows. Nothing under `hack/` was moved or renamed and no make-target contract changed, so the ccp entry does not fire. It gates on `hack/package.mk` and `hack/common-envs.mk`, neither of which is in the diff. The node prerequisites in `hack/e2e-prepare-cluster.bats` that ansible-cozystack mirrors by hand are untouched, and so is `.github/workflows/tags.yaml`. `docs/agents/` is internal contributor documentation, not a website source. No package was added, renamed or removed, and no `values.schema.json` or version enum changed, so the website and provider entries do not fire either. - [x] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: ### Release note ```release-note fix(ci): select-e2e no longer reports an empty selection when it cannot enumerate the Chainsaw suites, which made an escalation to the full suite indistinguishable from "skip Chainsaw" and left the E2E gate green with nothing run.

test(tests): let each bats file declare the EXIT traps it still holds (#3622)
<!-- Thank you for making a contribution! Here are some tips for you: - Use Conventional Commits for the PR title: `type(scope): description` - Types: feat, fix, docs, style, refactor, perf, test, build, ci, chore - Scopes are not an exhaustive list — pick the most specific scope for the change and extend the list when a genuinely new area appears. Examples: - System components: dashboard, platform, operator, cilium, kube-ovn, linstor, fluxcd, cluster-api - Managed apps: postgres, mariadb, redis, kafka, clickhouse, virtual-machine, kubernetes - Development and maintenance: api, hack, tests, ci, docs, maintenance - Breaking changes: append `!` after type/scope (`feat(api)!: ...`) or add a `BREAKING CHANGE:` footer - If it's a work in progress, consider creating this PR as a draft. - Don't hesistate to ask for opinion and review in the community chats, even if it's still a draft. - Add the label `backport` if it's a bugfix that needs to be backported to a previous version. --> ## What this PR does The ban on EXIT-trap cleanup in `hack/*.bats` was enforced by two lists inside `hack/cozyreport.bats`: one naming the files known to be clean, one freezing an exact trap count for each file that was not. Both had to be edited from whatever change moved them, and that is where the guard kept failing. It is worth being exact about how badly, because the history is sharper than "it went stale a few times". **The inventory was never correct on main for a single commit.** It landed in #3567 at 15:25:20. #3195 had landed `multus-install-cni-plugins.bats` carrying twelve traps at 15:24:37, forty-three seconds earlier. Replaying the old guard's own logic against the tree at the very commit that introduced it already gives `found != frozen`. Main then stayed red for roughly twenty-two and three quarter hours. The first repair, #3584, landed *already red* the next morning at 10:42:43, because #3548 had brought in `run-kubernetes-talos-diagnostics_test.bats` with eight traps at 10:40:03, under three minutes ahead of it. That fix was correct and bought zero green time. Green arrived only with the second repair, #3602. Neither pair of PRs shared a line, and each was green against its own base. That is the whole mechanism, and it is why a third one-line repair is not the answer. The mechanism is structural rather than careless. A change that adds a trap to its own file had to edit a string in a suite it otherwise never touches, so two changes sharing no line still invalidated each other: each stayed green against its own base, git merged both cleanly, and the guard went red only once the second one landed. A file *arriving* with traps was worse still, because nothing in its author's diff pointed at that string at all. That is exactly how `run-kubernetes-talos-diagnostics_test.bats` got in, twice. That contention is not in the past tense. Two open PRs are editing that one line right now, and they disagree about what it should say: #3575 adds `run-kubernetes-talos-diagnostics_test.bats=8` to it, repeating a repair that has already landed, and #3441 removes `select-e2e_test.bats=15` from it, because it converts that file. Neither PR is about EXIT traps. Both have to touch that string anyway, and whichever lands second is wrong until someone edits it again. So this PR is not fixing a red main. It removes the thing that keeps making main red, which is why it is worth more than the one-line fix that is now the established habit. One honest caveat about its own landing. The textual-conflict property is steady-state: a branch forked *before* the declaration exists has no line to disagree with, so it converts traps in its own file, merges clean, and the count only goes wrong once both sides are on main. I checked this against #3441, which takes `select-e2e_test.bats` from fifteen traps to zero. Merged after this, that file would declare fifteen and hold none. What the move buys even in that case is that the red names a file the branch already edited, the repair is one line inside it, and rebasing before merge catches it on the branch's own CI. None of those three held against the central inventory. Whoever merges this should expect one such adjustment on the conversion branches still in flight. So this replaces both lists with a declaration each file makes about itself: one `# EXIT-TRAP DEBT: N` comment in its leading comment block. A file carrying no declaration must install no EXIT trap. Growing or shedding a trap now fails in the file the change already edits, so two changes that disagree about a count get a real textual conflict instead of silently invalidating each other, and a change that leaves the traps alone edits nothing. **The include list is redundant, not lost.** It named the files proven clean, so that a trap reappearing in one of them would fail. Under the new rule those files carry no declaration, and a file with no declaration must hold zero traps, so a trap reappearing in any of them fails on its own, with no list to be on. Coverage widens rather than narrows: the two lists named twenty files between them, and the rule covers all fifty bats files under `hack/`, subdirectories included, plus the ones added tomorrow. Rebasing this branch onto current main is the property working. Main has since gained `hack/kubernetes-pre-delete-hook.bats` and `hack/tenant-pre-delete-hook.bats`, and `hack/cozyreport.bats` grew by some eight hundred lines. Neither new file installs an EXIT trap, so neither needed a declaration and neither needed an edit here; the rebase took no conflict at all. Under the inventory, each arriving file was a coin toss on whether somebody had remembered the string. To be precise about what the inventory could and could not do, since it is easy to overstate: it did *notice* a new file carrying traps. The string it compared was built by scanning the directory, so an arriving file appended a token and failed the comparison, which is exactly how main went red. What it could not do is let that file arrive without an edit in a foreign suite. Being seen and being absorbable are different properties, and only the second one decides whether two changes can land independently. The declaration is pinned in both directions. Declaring N while holding N+1 fails, obviously; declaring N while holding N−1 fails too. Without that second half the number becomes a ceiling and rots upward: somebody converts half a file, the declaration stays, and the guard quietly licenses traps that were removed long ago. It is read only from the leading comment block, under the shebang and above the first line of code. A `.bats` file is shell that writes shell, so the same line turns up inside a heredoc, a fixture writer or an expected-output string, where it is data belonging to one test; honouring it there would let an unrelated fixture excuse a real trap, silently, with nothing in that test's own diff looking like a declaration. A comment block is the region with no interior; stopping instead at the first `@test` would still read a line out of a helper's heredoc. Not every counted handler is debt. A trap inside an explicit subshell does not replace the one the `bats` binary installs, so a test failing inside `( … )` still prints its `not ok`, checked against a test-level trap in the same file, where the TAP line vanishes. `hack/e2e-test-openapi.bats` kills a backgrounded `kubectl proxy` exactly that way, and "convert it like the others" would leak a process holding a fixed port and wedge the next run. Its declaration now records the carve-out instead of scheduling a conversion, and because the ratchet is exact in both directions, *removing* that trap fails too, so the count protects the construct rather than marking it for deletion. `docs/agents/e2e-testing.md` previously scoped this exception to Chainsaw `script` steps only; it now names the BATS subshell case as well. The counting bounds the keyword and the signal the same way, at any character that cannot be part of an identifier, and matches the signal in either case. Whitespace on the right missed `trap … EXIT; cd "$tmp"`; whitespace on the left missed `tmp=$(mktemp -d);trap … EXIT` and `(trap … EXIT; true)`; upper case missed `trap … exit`, which bash and dash both install. All of those are real handlers that scored zero. The left boundary is the one worth dwelling on, because the inventory being replaced had none at all and *did* catch the semicolon form. Getting it wrong here would have narrowed coverage while the commit claimed to widen it. A plain word boundary is not enough either: `bootstrap ` ends in `trap `, and it has to keep scoring nothing, or the documented answer to a red guard (add a debt line) would buy a file a permanent licence for one real trap to silence a line that has none. Two handlers sharing one line are reported rather than counted, because the count is a count of lines and the second would otherwise arrive free. Splitting such a line properly needs a shell parser, since a semicolon inside a handler's own quoted action is not a separator, and guessing wrong undercounts, the one direction a ratchet cannot afford. **What this does not fix.** The declaration is still a loophole: a new file can write `# EXIT-TRAP DEBT: 8` instead of cleaning up, and nothing here makes that impossible. What changes is that the admission is local and visible. It sits at the top of the file it excuses, in front of whoever reviews that file, instead of being a number in a neighbouring suite nobody in that review is reading. Today's loophole is the same size and invisible. Three more limits, all stated in the guard's own header rather than left to be discovered. The scan is lexical, so a signal computed at runtime and a quoted action spanning physical lines without a backslash are both invisible. An exact count catches addition and removal but never substitution: swap the openapi file's subshell trap for a test-level one and the total stays 1. And the scan reads `.bats` only, so a handler arriving through a sourced `.sh` is outside it. `hack/e2e-chainsaw/_lib/run-kubernetes.sh` installs two right now, and each is benign for its own reason rather than by design: the one in `cozy_capture_tenant_talos` because that function is declared with `(` and so runs in a subshell, the one in `run_kubernetes_test` because no `@test` calls it despite being declared with `{`. Three `hack/*.bats` source that library, and two tests in the converted file call `cozy_capture_tenant_talos`, so flipping a single `(` to `{` reinstates a test-level handler in both of them with the guard green. Widening the scan to `.sh` would mean counting handlers that are correct in a script and wrong only in a test body, so the honest answer is that this is where the instrument stops. Three further boundaries, recorded here so they land as known edges rather than as surprises. The old include list also failed when a file named on it disappeared from the tree; the new rule can only judge a file that is present, so a deleted converted file goes unnoticed. That is a genuinely smaller check, though its absence shows up in the diff that deletes the file. The guard's own failure messages are code lines, so they are scanned by the pattern they belong to: they pass today only because no bare `EXIT` or `0` happens to follow the keyword in any of them, and a rewording that introduced one would make the file demand a debt of itself. It fails loudly rather than quietly, and the fixture writers and test titles already split the keyword from the signal for this reason, but the messages do not. Finally, `docs/agents/e2e-testing.md` bans test-level `EXIT` *and* `RETURN` traps, while every mechanical guard this repo has had, the one being deleted included, matches only `EXIT` and `0`. `hack/` holds no RETURN trap today, so nothing regresses here, but half of that documented rule has never had an executor. The guard moves out of `hack/cozyreport.bats` into `hack/bats-no-exit-trap.bats`, because its subject is every unit suite under `hack/` and not the report collector it grew up in. Living inside `cozyreport.bats` is precisely why unrelated PRs kept converging on one line. `hack/md-no-hardwrap.bats` is the neighbouring precedent. Separately, the eight EXIT traps in `hack/run-kubernetes-talos-diagnostics_test.bats` are converted to end-of-body cleanup rather than given a declaration. That file was written six weeks after the ban was documented, so "it predates the rule" is not available to it, and handing it a debt is literally the move that failed the last two times. The remaining files keep their declarations, since a mass conversion would collide with the branches that own them. One note on where the prose sits. The guard's own header carries only what a reader has to keep true: why the ban exists, the two carve-outs, where the declaration lives and why there, that the count is exact in both directions, why the marker is anchored at column zero, and where the lexical scan stops. Everything above about *how* the inventory failed (the timestamps, the PR numbers, the arithmetic) is deliberately not in the file. It is true today and will rot on its own; a comment nobody is obliged to maintain is how a file grows a paragraph that is quietly false. ### Screenshots <!-- REQUIRED for UI changes: attach screenshots or screen recordings demonstrating the visual impact of your changes. PRs with UI changes without screenshots will not be merged. --> ### Downstream repositories <!-- Cozystack is upstream for repositories that are NOT kept in sync with it automatically, and nothing in CI compares the two sides, so a change here can break them silently.

IF YOU ARE AN AI AGENT OR AN LLM, THIS IS PART OF THE TASK, NOT A FORM TO FILL IN: 1. Walk the trigger map against the actual diff of this PR, file by file. Do not decide from the PR title or from your memory of what you changed. 2. For every repository you tick, open the follow-up PR there and link it on the same line. A ticked box with no link claims work that does not exist, which is worse than an empty box. Search that repository for an open PR or issue covering it first, and link that instead of filing a duplicate. 3. When the follow-up is out of scope, or needs a decision that is not yours to make, open an issue in that repository instead, link that, and say so in the PR body. Do not push a speculative PR into another repository just to fill a line here. 4. Do not tick "No downstream repository is affected" to make the checklist go away.

fix(tests): report a data-plane capture cut short by its backstop
Both callers of the data-plane collector wrap it in a wall-clock backstop and threw the result away with `|| true`, while the previous-instance logs leg sitting beside each of them records the exit status and prints "INCOMPLETE (exit N); kept what landed in ...". When a backstop killed the collector, nothing said so, and a truncated dataplane/ directory read exactly like a complete one that found little. The collector itself now names every read of its own it could not finish, which left these two call sites as the only remaining way for that leg to die without a word. The Chainsaw one is the tighter of the pair -- 300s against 600s, because it shares an op envelope with the snapshot leg -- so it is both likelier to fire and more expensive to leave silent. In each place the status is read, never propagated: a diagnostic still cannot change a test's outcome. Assisted-By: Claude <noreply@anthropic.com> Signed-off-by: Aleksei Sviridkin <f@lex.la> |

fix(e2e): report an LB no probe reached as unprobed, not reachable
Five inputs walked into the LB probe gate's skip branch having run zero probes, and all five came out as "probe: LB reachable or not probeable ... -- reachable, skipped": no node to probe from, a Service with no port, a probe node the lookup says runs no kube-ovn-cni pod, a host netns with no nc/curl/wget, and an exec that could not run (no timeout on PATH, exec denied, the pod gone mid-probe). None of them observed the address. An e2e image without a probe client would stamp every LoadBalancer in the cluster reachable and skip the whole heavy capture, which reads as a healthy datapath. A sixth way in, the cni-server lookup not answering at all, already reported unknown and still does. Zero probes now routes to that same explicit unknown outcome, and each way of getting there carries a reason the run can actually support. The two structural inputs are named where they are detected. The rest are told apart by the shape of the outcome set, which is the only place the difference survives: the probe helper emits an explicit unknown token only when the lookup itself did not answer, so a set that is present and wholly unknown names the lookup, while an empty set names the three ways a probe dies after the lookup answered. Those three stay together -- the exec's status is swallowed by design, since this collector never fails a job -- but none of them is reported as a lookup that went unanswered, because it did not. The reachable line now says which evidence produced it. Assisted-By: Claude <noreply@anthropic.com> Signed-off-by: Aleksei Sviridkin <f@lex.la> |

fix(e2e): say when an LB backend is unread rather than absent
The two EndpointSlice reads in the LB section discarded stderr and were interpreted by emptiness alone, so a refused or cut-off read wrote the same `<none>` into the artifact that a Service with no endpoints does. That is the assertion without the refutation: a reader holding the uploaded report, and not the run, has no way to tell which happened, and the section is at its weakest exactly when the apiserver is struggling. Both reads now carry their status beside the value, in the vocabulary the per-node captures already use. Reporting the status arms a landmine the silence used to hide: the target port was read with a jsonpath indexing `items[0]`, and client-go's evalArray has no allowMissingKeys escape, so an empty list is a hard error and kubectl exits 1. A Service with no endpointslices is an ordinary answer here and would have started reporting as a failed read, so the read now asks with `items[*]` -- empty output, exit 0 -- and takes the first value, the way the pod lookups already do.

fix(e2e): skip a tcpdump leg whose node was never identified
pod_on_node turns its node argument into `--field-selector spec.nodeName=<node>`, and an empty node asks for pods whose nodeName is empty -- the unscheduled ones. So an unidentified node did not yield "no pod found": it yielded the first pending kube-ovn-cni pod in the namespace, and the tcpdump then ran against a pod that is not on that node and may not be running at all. Both halves of the cross-node capture had this, and each gap opens in the very state its own leg exists to characterise. The announcer is unknown exactly when MetalLB is misbehaving; a Service with no ready endpoint is the ordinary shape of an LB outage, and the endpoint side carried two such lookups, the cni-server pod and the backend's OVS interface. In either state the artifact came out holding a tcpdump from an unrelated pending pod under an ANNOUNCER or ENDPOINT label, or a confusing exec failure -- both pointing away from the actual problem. Each leg is now guarded the way the static capture above it already was, and records in the artifact that it was skipped rather than leaving a silent gap. The guards stay at the call sites rather than moving into pod_on_node: that helper serves five callers, and an early return there would have to invent a status for a lookup nobody made.

fix(e2e): drop truncated records in the data-plane capture filters
The record filters selected rows by field value and never checked the field count, so a list cut mid-record parsed as a valid record: an IP cut mid-octet still looks like an IP, and a cut inside the nodeName column still looks like a scheduled pod. The capture then probed an address the cluster never had and opened a per-node file for a node that does not exist -- confidently labelled data about objects that are artifacts of the cut. The kubectl jsonpath behind each filter emits a fixed field count per record, so a shorter row is a fragment by construction: seven for the Service list, six for the pod list, five for the endpoint list. Dropping it costs the reader nothing -- the read's own note already says the list did not finish. The endpoint filter is the one that matters most, because it stops at the first row it accepts: a fragment at its head is not one bad row among many, it is the backend, and its half-parsed node is the node every endpoint-side capture then aims at. Where the class lives in this file, so the map does not have to be rebuilt: four sites parse records, and the two loops walking pods and LoadBalancers are not among them -- they consume what these filters already returned, so a cut is caught upstream of them. Three of the four are the filters guarded here. The fourth, the MetalLB speaker loop, is at the limit of what a field count can do: its records carry two fields, a cut in the first leaves no separator and its existing emptiness guard already rejects that, and a cut in the second delivers every separator, which nothing in-band tells apart from a genuinely short node name. That limit is not confined to the speaker loop, and the comment on the first filter now says so rather than implying a guard that holds everywhere: a cut inside any record's LAST field passes a field count. It lands on a display-only column for Services, and on a decision column for the other two, where a truncated value matches neither state being excluded and the row is kept -- over-capturing rather than dropping evidence.

docs(e2e): name both callers of the data-plane capture in its header
The header credited cozytest.sh alone, while the Chainsaw global catch invokes the same script under a different wall-clock backstop -- 300s against cozytest.sh's 600s. A reader sizing this collector's budget against the caller the header names can still overrun the one it omits, and the arithmetic further down the file already assumes both exist.

test(helm): sweep packages/tests so the library suite stands on its own
The helm unit sweep iterates packages/apps, core, extra, system and library, and never visits packages/tests. The cozy-lib-tests suite — the whole test coverage for a helper library 34 charts consume by symlink — runs only because packages/library/cozy-lib/Makefile carries a line delegating its own 'test' target to it. Deleting that one line takes the visited-package count for the suite from one to zero and the executions from one to zero, with the sweep still exiting 0 and still printing "All Helm unit tests passed": the no-suites backstop is satisfied by the other directories. Nothing else in the sweep could have caught it. Every check it makes — the Makefile test, the `make -n test` probe, the collection of failing directories — runs inside a directory the loop already reached, so a package that never enters the loop takes all of them with it. What is left is tests_found, and that counts suites across the whole run rather than per package, so the other directories keep it satisfied. Add the directory to the loop. It holds one package today, so the sweep grows from 76 executed suites to 77, and that suite costs between 0.1s and 0.3s over six runs against a sweep of roughly 31 seconds. The delegation stays for the ergonomics of `make -C packages/library/cozy-lib test`, which means cozy-lib-tests now runs twice; the point is that neither run is load-bearing alone. Covered by a new bats file: one test that the sweep reaches the directory and executes what it finds there, one that a red suite there still fails the sweep rather than being swallowed.

fix(ci): treat a disabled chainsaw suite as inert in test selection
Editing hack/e2e-chainsaw/backup/chainsaw-test.yaml.disabled selects the whole Chainsaw suite. The per-suite rule reads the suite name off the directory and ignores the suffix, so the change selects "backup"; the final intersection against the suites that actually exist finds no such suite and empties; and the safety net for an empty selection escalates to the full run. A disabled suite is registered nowhere and executed by nothing, which makes its edits the one file class that provably cannot regress a test. The mapping had it backwards: they bought the most expensive outcome the selector has. Rare in practice, and paid on every commit by anyone grooming or re-enabling such a suite. Classify *.disabled as inert ahead of the per-suite rule, and record it alongside the other rules that select nothing so the header stays an accurate enumeration. The safety net keeps its job for paths no rule has looked at, which is what it was added for. Signed-off-by: Aleksei Sviridkin <f@lex.la> |

fix(ci): stop select-e2e from deciding on inputs it never checked
Three holes on the same seam: the script builds a list, never looks at whether the command that built it succeeded, and then decides from the empty result. The dependency indexes are built as `$(build_owners_index | sort -u)`, where the function is a single yq. A pipeline carries the status of its last command, so the script sees sort's zero and `set -e` never fires: a missing binary or a malformed source leaves the index empty, every changed path falls through to escalation, and CI runs the full Chainsaw suite on every pull request. The direction is safe and that is the problem — an empty index and "no owners matched" print the same thing, so the symptom is a full run, which reads as the conservatism the selector is supposed to apply. Selection can stay switched off indefinitely with nobody signalled. Check each half's status on its own and name yq once on stderr before taking the fallback the empty index would have reached anyway. The suite list one line up has the identical shape and a worse consequence: `$(find ... | sed | sort)` reports sort, never find, and errors went to /dev/null. That list is what every escalation prints. So a find that failed produced an empty list, and "escalate to the full suite" then emitted a blank line — which both e2e lanes read as "skip Chainsaw" before posting the required "E2E Tests" status green. The one outcome that means run everything delivered a run of nothing, on the pull request that earned a full run. Capture find on its own, check it, let its errors through. A failing find is not the only way to end up with an empty list, and the escalations are not its only reader, so the check sits once where the list is built. The examples/backups/<app>/ rule escalates nothing and still membership-tests against that list: with it empty the test fails, the app is not selected, and an edit to a backup harness that should run its suite reports nothing to run — output identical to a legitimately empty selection, on a path no escalation guard would ever see. An empty list is a broken enumeration, a moved directory or a wrong working directory, not a project without tests. Refuse to answer at all. Both lanes run the step under `bash -e`, so a non-zero exit fails the job rather than falling through to the empty selection this is here to prevent. Each is covered by a test that stubs the failing component and asserts both the exit status and that the script names what broke. Signed-off-by: Aleksei Sviridkin <f@lex.la> |

test(ci): assert the whole suite list where select-e2e must escalate
Fourteen tests read `[ "$(echo "$output" | wc -w)" -gt 5 ]` to mean "the full suite was selected". A word count clears that bar on any selection of six or more, and the tree holds twenty-one suites, so a selector bug that escalates to most of them but not all stays green in every one of those tests. Partial escalation is the failure worth catching on exactly these paths; the threshold is blind to it and only sees total failure. Compare against the whole list instead, derived the way the script's full-suite branch derives it rather than pinned as a literal, so adding or disabling a suite does not need fourteen edits here. On a one-suite drop injected into that branch, thirteen of the converted tests go red; under the threshold all thirteen stayed green. The fourteenth is the cilium case, and equality shows it was never a full-suite path: packages/system/cilium is owned by cozystack.networking and resolves through the dependency graph, which reaches nineteen of the twenty-one suites. The two it misses, kuberture and securitygroup, sit on sources that are not *-application, and the source-to-suite mapping covers only those plus external-dns by name. Both controllers declare cozystack.networking as a dependency, so a CNI change that breaks either one runs neither suite. That gap belongs to the selector; the test is renamed for what it measures and pins the nineteen, so closing the gap fails it rather than passing unnoticed.

docs(e2e): name every suite that stayed on the BATS runner
Two files enumerated the BATS suites and both stopped one short. The global catch in .chainsaw.yaml describes itself as the Chainsaw analog of the EXIT-trap host snapshot in hack/cozytest.sh, and said that runner "only covers the BATS install/openapi tests". The README said cluster bootstrap and the OpenAPI checks remain BATS and named only two files. Both miss e2e-prepare-cluster.bats, which packages/core/testing/Makefile drives through the same runner, and which is the suite whose failures leave the sandbox in the state hardest to reconstruct afterwards. docs/agents/e2e-testing.md already listed all three, so the count was answerable from the tree; it just disagreed with itself depending on which file you opened. The .chainsaw.yaml paragraph is reflowed because the correction is longer than the line it replaces; no other wording changed.

docs(hack): correct both budget claims in the capture-gate rationale
Two numbers in this comment block no longer described the code. The snapshot leg's cost was given as 360s, the deadline passed to timeout. The leg is invoked as `timeout -k 30 360`, so a hung crust-gather is signalled at 360s and killed at 390s, and the trap waits out the later one. The comment 40 lines below already said 390s, as does the op-budget arithmetic in .chainsaw.yaml; the three now agree, and the number names the grace it includes, because the data-plane leg beside it is quoted at its bare deadline. The data-plane leg was still described as having no bound on its first pod list, and billed at the full 600s on that basis. Its reads carry their own ceilings now, 28s for a list and 20s for a single read, so the leg returns in tens of seconds and the paragraph's bottom line overstated the bill it exists to justify.

fix(tests): bound the e2e data-plane capture's reads and stop inferring absence from silence (#3659)

Every `kubectl` read in it was unbounded, so a read against a wedged apiserver hung until the caller's own backstop killed the script, and then no capture file was written at all. The run that most needs the diagnostic is the run least likely to produce one. Each read now carries its own bound, 20s for a single read and 28s for a list, well inside the 300s the callers allow. Bounding the reads creates the second problem, which is most of this diff. A bounded read that gives up returns empty, and empty was already how the script recognised "there is nothing here". Five places turned a read that never answered into a fact about the cluster: no affected pods, no ovn-central, no LoadBalancer Service, no cilium-agent on a node, and a LoadBalancer recorded as reachable. Two of the five only became reachable because of the bounds. Before them the script died instead of writing the file, so a lookup that never answered could not be recorded as a pod that is not there. Each of those claims now has a counterpart chosen by the status of the read that produced it, and the counterpart says what is left unknown rather than what the read did. The last one is the subtlest, because nothing about it looks like a claim of absence: the probe resolves a cni-server pod before probing, and a lookup that never answered produced no probe outcome at all, which the decision helper read as "nothing failed" and the artifact stamped as reachable. That is a verdict about an address the script never touched. The probe now emits an explicit unknown, and a set of outcomes that is entirely unknown stays unknown. Only a wholly unknown set: one unrun probe beside real failures leaves the failures standing and still captures, because they are the evidence the capture exists to characterise. Every note ships beside the capture it explains, not only in the job log, because the reader who has the uploaded report and not the run is exactly the reader who cannot otherwise tell a capture that found nothing from one that never ran. Both sibling collectors already hold that contract. The middle commit is a separate and measurable thing. Each per-node pod lookup was issued up to three times per node; it is asked once now and memoised, with only answers and cutoffs cached, since an instant failure costs nothing to re-ask and caching it would make one transient permanent for the whole run. On an 8-pod, 8-node stub that is 264 kubectl calls down to 229 and 59 per-node lookups down to 24, with byte-identical output. Deliberately left, and worth naming so nobody reads this as the whole class. The two EndpointSlice reads still discard stderr and report neither outcome. The "reachable, skipped" wording still covers every path that reaches it having run zero probes, among them an unresolved probe node, a `_lbport` of 0, a cni-server image carrying none of `nc`, `curl` or `wget`, and a failure of the probe `exec` itself rather than of the lookup before it; that leftover is tracked in #3658. And the three call sites still disagree about what a partial answer means: `host_http_probe` discards a name that arrived with a non-zero status, while `capture_node` and `capture_lb_node` use a non-empty name regardless of it. All of these are verbatim at the merge base and this diff does not change their behaviour. Covered by 39 cases in `hack/capture-dataplane.bats`, each branch pinned by a stub that answers one read and fails another, and each with a positive anchor so a stub that stops short of the branch fails rather than passing quietly. relates to #3642 ### Screenshots <!-- REQUIRED for UI changes: attach screenshots or screen recordings demonstrating the visual impact of your changes.

feat(kubernetes): let a node group log the guest serial console (#3637)
## What this PR does Both tenant Kubernetes e2e suites keep missing the node-Ready budget with zero Nodes registered, and the time goes inside the guest, between the worker VMI reaching Running and Talos asking for its apid certificate. Nothing collected today reaches that window. The in-guest capture the harness already has drives `talosctl`, so it needs the apid the worker never got to, and the management side has neither a Node nor a certificate request to read. Four attempts at this failure have been designed from outside the guest; the most recent raised the budget from 12m to 18m and the same fingerprint came back at the new deadline. KubeVirt can stream a VM's guest serial console into a `guest-console-log` container beside virt-launcher, readable with `kubectl logs` and needing nothing from inside the guest — no talosctl, no client certificate, no helper Pod, no reachable apid. That is the one property this failure class demands, so this turns it on for the suite's worker node group and collects it into the diagnostic bundle when node-join fails, ahead of the `talosctl` capture that cannot describe the same runs. Reads start at the beginning of the stream rather than tailing it: a guest that repaints its console would push the boot output out of any `--tail` window, while `--limit-bytes` truncates from the far end instead. Every read is bounded, and the walk stops at a cap that records both counts, so the collector cannot become an unbounded term in a failure path that already runs several others under one deadline. A read that returns no console is not filed as a quiet guest. Three outcomes get three labels, because only one of them says anything about the guest: the read failed and returned nothing, the read succeeded and returned nothing, or it broke off part way. Each read's stderr is kept beside the capture rather than inside it — kubectl's own `container guest-console-log is not valid for pod` would otherwise fill the file, and a console that never started would read as one that had spoken. That case is the headline one here, so the Pod state and events that explain it are collected alongside, once for the whole selector. The switch is a new opt-in `logSerialConsole` on a node group, off by default. It renders nothing unless set to true, including when set to false, because the `KubevirtMachineTemplate` is content-hash named and a byte emitted for a group that did not ask for it renames the template and rolls every live worker VM on upgrade. I verified that by rendering the base tree and this branch: absent and explicit-false produce a byte-identical template name on both charts. Worker VMs come from two charts, `kubernetes` and `kubernetes-nodes`; both carry the field, and the golden-parity check between them gains a case that keeps their output identical. The passing path checks separately that the container actually attached, and runs that check last, after everything the suite exists to prove — a debugging aid should not preempt the assertions that cover the cluster. Without it the suite would first learn the setting was inert in the one run that needed the console, when it can no longer be recovered. Relates to #3513. ### The risk this carries, stated up front The platform turns serial console logging off cluster-wide in the KubeVirt CR. That setting is a mitigation added in February 2026 for kubevirt/kubevirt#15989, where the `guest-console-log` container kept virt-launcher from starting and left VMs in `PodInitializing`. A per-VM `logSerialConsole` takes precedence over it — `isSerialConsoleLogEnabled` reads the VMI field first and only then falls back to the cluster setting — which is what makes this work, and also makes this the first thing on the platform to go through that mitigation. The mitigation was written against KubeVirt v1.6.x; the platform now ships v1.8.4, and the upstream issue is still open with no reproduction reported either way on the newer version. So the first run of these suites is also the experiment, and it doubles as a revalidation of that February mitigation on the version actually shipping, which nobody has done. The two outcomes are distinguishable rather than ambiguous: kubevirt/kubevirt#15989 shows up as virt-launcher wedged in `PodInitializing` with the VMI never reaching Running, while the failure this instruments shows the VMI Running and zero certificate requests. A red run with the first signature is an answer, not noise — and the collector is built so that it says which one happened instead of reporting silence. The blast radius is small: the product field is absent by default and only the e2e node group sets it, so backing this out is one line. The revert criterion, stated before the run rather than after it. If worker virt-launcher Pods sit in `Init` on `guest-console-log` and no Node registers, kubevirt/kubevirt#15989 still reproduces on v1.8.4: drop the `logSerialConsole: true` line from the e2e node group, keep the chart field, and the upstream issue gains the reproduction on a current version that its thread does not have. If the Pods reach Running and the console logs carry boot output, the mitigation is a candidate for removal platform-wide, which is its own change. Either way the run answers something that was open before it. Dropping `virtualMachineOptions.disableSerialConsoleLog` outright was the alternative. It is a smaller diff and needs no values key, but it exposes every VM on the platform to a race nobody has re-tested, instead of one node group in one test. That is its own revalidation exercise and belongs in its own change, on evidence this one produces. ### Verification `make unit-tests` passes. The new bats suite runs green under both `bash` and a `dash` `/bin/sh`, which matters because `hack/cozytest.sh` is `#!/bin/sh` and an earlier revision of this branch carried a bash-only construct that failed silently there. Every test in it is killed by a specific mutation of the code it covers. Both charts' helm-unittest suites pass, the golden-parity script reports byte-identical output across all four cases including the new one, and `make generate` is idempotent at the repo root. Reviewed by Claude across several rounds and by an independent second reader; the review loop found and fixed real defects in this branch, including a green-path check that had become unable to report the one thing it existed for. ### Screenshots Not a UI change. ### Downstream repositories - [ ] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [x] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: https://github.com/cozystack/terraform-provider-cozystack/issues/26 - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: ### Release note ```release-note feat(kubernetes): worker node groups accept `logSerialConsole`, which streams a worker VM's guest serial console into a `guest-console-log` container readable with `kubectl logs`.

A unit runner has kubectl and no cluster, so a red unit test walked into those legs on its way out and paid for snapshots of nothing. What that costs turns on how kubectl fails, which is why the defect survived: against an endpoint that refuses it is a second, and locally that is what happens. Against one that hangs, which is what a runner with a context pointing at a torn-down cluster has, I measured ~28s for the previous-logs leg and the full 600s for the data-plane one. The 28s is the leg self-bounding its own pod list, so it never reaches the 300s ceiling above it; the 600s is real, because that leg's first pod list carries no bound of its own. Ten minutes of dead waiting for a failure that should have cost seconds. Where crust-gather is installed too, the bill stops being empty and starts being wrong. That leg needs no reachable cluster to fire, only an ambient KUBECONFIG, and it will spend up to 360s snapshotting whatever cluster the current context happens to name. The gate now keys on the `e2e-` prefix, read from the suite's own name or from the directory holding it. At the top level that is the split the project already sorts on: the Makefile builds `BATS_UNIT_FILES` as `$(filter-out hack/e2e-%.bats,$(wildcard hack/*.bats))`, so a top-level `e2e-*` suite is exactly the one `make unit-tests` refuses to run and `packages/core/testing/Makefile` runs against a live cluster. That wildcard is not recursive, and `hack/e2e-apps/` holds live-cluster suites whose own filenames carry no prefix, so the directory is checked too. Matching the basename alone would take the captures away from suites that need them, which is the opposite of the point. Every leg, bound and message on the e2e path is unchanged. It is deliberately not a reachability probe, though a probe would also tell a cluster from a bare binary. A failing e2e run is frequently one whose apiserver is degraded, and a probe answering "no" there would skip the snapshot in precisely the case the snapshot exists for. A diagnostic should not condition itself on the health of the thing it diagnoses. The test drives the runner as a subprocess over fixtures that differ only in where they sit, with stub kubectl and crust-gather on PATH so neither direction is decided by a binary being absent. Each leg is pinned by the artefact it leaves in the report tree rather than by the one leg that echoes, so no single leg can be ungated without a test going red; that was checked by ungating each in turn. The two armed cases are the positive control for the disarmed one, whose assertion is negative and would otherwise pass just as well against a harness that ran nothing. Relates to #3626. ### Screenshots <!-- REQUIRED for UI changes: attach screenshots or screen recordings demonstrating the visual impact of your changes. PRs with UI changes without screenshots will not be merged. --> ### Downstream repositories <!-- Cozystack is upstream for repositories that are NOT kept in sync with it automatically, and nothing in CI compares the two sides, so a change here can break them silently. Which change forces what, and which file to touch, is the trigger map in docs/agents/contributing.md under "Downstream Repositories". Walk it before you tick anything.

Do not decide from the PR title or from your memory of what you changed. 2. For every repository you tick, open the follow-up PR there and link it on the same line. A ticked box with no link claims work that does not exist, which is worse than an empty box. Search that repository for an open PR or issue covering it first, and link that instead of filing a duplicate. 3. When the follow-up is out of scope, or needs a decision that is not yours to make, open an issue in that repository instead, link that, and say so in the PR body. Do not push a speculative PR into another repository just to fill a line here. 4. Do not tick "No downstream repository is affected" to make the checklist go away.

fix(e2e): an unanswered read is not the same as an absent thing
Five places turned an empty or missing result into a fact about the cluster: no affected pods, no ovn-central, no LoadBalancer service, no cilium-agent or ovs on a node, and a LoadBalancer recorded as reachable. Each is also what the script produces when the read behind it never answered, and with a note now saying the read failed, lines sat next to each other and disagreed. Each claim has a counterpart chosen by the status of the read that produced it, and each says what is left unknown rather than what the read did: no scheduled NotReady pods / whether any pod is affected no ovn-central pod in <ns> / whether <ns> runs ovn-central no Service type=LoadBalancer / whether any LoadBalancer needs capturing (no cilium-agent pod found) / could not determine whether one runs there LB reachable, skipped / whether the LB is reachable is unknown The last of those is the subtlest, because nothing about it looks like a claim of absence. host_http_probe resolves a cni-server before probing, and a lookup that never answered produced no probe outcome at all, which the decision helper read as "nothing failed" and the artifact stamped as reachable -- a verdict about an address the script never touched. The probe now emits an explicit unknown, and a set of outcomes that is entirely unknown stays unknown rather than collapsing into either answer. Only a wholly unknown set: one unrun probe beside real failures leaves the failures standing and still captures, because they are the evidence the capture exists to characterise. Wording that describes the read instead would be wrong in a case these bounds create. A list can fail after emitting rows, since a bound firing mid-stream leaves output on stdout and 124 in $?, so an empty result with a non-zero status can mean the read said nothing or that it said only uninteresting things. Before the bounds a read either answered or hung forever, and a partial answer was not a state this script could reach. For the same reason a failure note is unconditional on the status while the consequence -- skipped, unresolved -- is stated only by the branch that takes it, which is why the note inside pod_on_node names none at all: five call sites share it and their consequences differ. Two of these five are in the artifact rather than the log, and they are there because of the bounds. Unbounded, the per-node lookup blocked until the caller's backstop killed the script and no capture file was written; bounded, the script survives and writes the file, so a read that never answered would have been recorded as a pod that is not there or an address that answered. pod_on_node returns its status with the name and the memo stores it, since a hit that dropped it would launder a cutoff into a confident absence. The status travels packed with the value through stdout because every caller reads the helper through a command substitution, where a variable dies with the subshell -- the same property that makes the memo itself a file. Only answers and cutoffs are memoised: an instant failure costs nothing to ask again, and caching it would make one transient permanent for the whole run. Every note also ships beside the capture it explains, not only in the job log, because the reader who has the uploaded report and not the run is exactly the reader who cannot otherwise tell a capture that found nothing from one that never ran. Both sibling collectors hold that contract and this script's notes are modelled on them. The two phrasing helpers move above the sourcing guard so the unit suite can assert their branches directly. The stderr sink stays below it, because anything created above is created again by every test that sources this file and by every host that exits early for want of kubectl. What is deliberately left is the same distinction for the two EndpointSlice reads, which still discard stderr and report neither outcome. Each branch is pinned by a stub that answers one read and fails another, each partial-answer case by a stub that emits a row and then fails, the artifact cases in the artifact rather than the log, and the memo's status round-trip by consuming one lookup from both a miss and a hit. Every one of them carries a positive anchor as well, so a stub that stops short of the branch fails rather than passing quietly.

perf(e2e): ask each per-node pod lookup once
The same (namespace, label, node) is asked up to three times per affected pod across the sections of this script. That was free while the first call hung forever and the script died inside it; with a per-read bound each repeat costs its own timeout, and against a wedged apiserver the repetition becomes the largest consumer of the caller's envelope -- enough that a 300s budget buys two pods where it could buy five. Answers are memoised, empty ones included: "there is no cilium-agent on this node" is exactly the lookup worth not repeating. The memo is a file rather than a variable, which is not a style choice. The walk over affected pods runs on the right-hand side of a pipeline, so it executes in a subshell and a variable memo is discarded at the end of it, leaving every lookup to be paid for again in the sections that follow. With the variable form the suite still recorded each of the three lookups twice. That is also why this is not the shape of the node memo above it, which is a space-delimited string matched with a case glob and is correct for a dedup living entirely inside the walk. Keys are compared as whole tab-separated fields, so the '=' inside a label selector is ordinary payload; what the scheme rests on is that no namespace, label selector or node name contains a tab, which Kubernetes names and selectors cannot. An empty pod list is also separated from one that never answered, so the branch below it stops reporting a failed read as a cluster with nothing wrong. Pinned by a stub that records every per-node lookup it is given: the test fails if any is issued twice. Assisted-By: Claude <noreply@anthropic.com> Signed-off-by: Aleksei Sviridkin <f@lex.la> |

fix(e2e): bound the dataplane capture's reads and name why one failed
Six `kubectl get` calls ran with no bound of their own, while all 27
`kubectl exec` calls in the same script went through one. Against an
apiserver that hangs rather than refuses, the first of them -- the
cluster-wide pod list -- held the script until the caller's backstop
killed it, so the capture wrote nothing at all. From the Chainsaw catch
that is worse than empty: the run is cut off by the outer `timeout -k`
and the script says nothing about having been cut short, so a truncated
capture reads exactly like a complete one that found no affected pods.
Measured against a kubectl stub that never returns: before, the script
was still blocked on its first call when a 60s backstop killed it;
after, it reaches its own end and says which read was cut off and what
that leaves missing. Roughly 4s at a 1s bound, 40s at the 20s default.
A per-read bound buys forward progress, not a smaller total. The sum of
the bounds here is far past any caller's envelope and deliberately so,
because the MAX_PODS and MAX_LBS caps bound work while the outer
`timeout -k` bounds wall clock. What changes is that no single hung read
can consume that envelope before anything is written.
The reporting around them is built to survive being read by someone who
was not there. Only 124 and 137 may name a timeout, since those are the
only statuses a bound produces and every other one is kubectl answering
-- refused, denied, a kind the cluster does not serve -- so the reads
keep their stderr instead of discarding it and quote it back. 137 is
described as what it is, a SIGKILL that cannot be told apart from the
bound's own kill grace. Notes print through `printf` rather than `echo`,
because under /bin/sh echo expands backslash escapes and kubectl's
stderr now flows through the logger: a message holding a literal \n
would otherwise split the note and forge a second "[capture-dataplane]"
line that reads as this script's own verdict, which needs no malice
given the jsonpath in these reads contains {"\n"} and kubectl quotes the
expression back when it fails to parse it.
The per-node lookups ask with `{.items[*].metadata.name}` rather than
`{.items[0]...}`. client-go's evalArray has no allowMissingKeys escape
the way evalField does, so indexing into an empty list is a hard error
and kubectl exits 1 -- which meant nothing while the status was
discarded, and would report "there is no cilium-agent on this node", the
ordinary answer, as a read that failed.
The tests drive the script as a subprocess against a stub kubectl that
hangs, fails instantly, or returns a forged line, and read what it
wrote. The stub that proves forward progress answers the pod list and
hangs afterwards, so the walk over affected pods is actually entered.

docs(ci): record what escalating on the non-PR workflows costs
Three of the four workflows on the escalation list cannot be exercised by the run they trigger. `e2e-fork` runs on `workflow_run`, which always takes the default-branch copy; `e2e-tag` runs on `workflow_call` from a tag push; `nightly` runs on a schedule. Only `pull-requests.yaml` is executed from the pull request's own head, so only there does escalating test the edit rather than the tree around it. That argument existed in the reference doc and was removed by this branch rather than answered, and the list it argued against is what replaced it. Measured over six months of main, 26 commits touch one of the three with no other escalating path; each now pays a full Chainsaw run it used to skip, on a suite whose flake rate is the reason people avoid running it for nothing. Keeping them is defensible: the rule stays one idea rather than two, and dropping them leaves those files inert, which reads as an oversight rather than a decision. What was not defensible was paying it silently. The trade now sits next to the pattern that makes it, with the number, so the next person weighing it starts from measurement instead of rediscovering the mechanism. The reference doc points there rather than carrying its own copy. Assisted-By: Claude <noreply@anthropic.com> Signed-off-by: Aleksei Sviridkin <f@lex.la> |
