Design companion to #223: Job shape (one Job per skyhook/package/stage/node), completion flow with a persisted processed-once marker, outcome-based TTL, naming/rerun rules, upgrade dual-path, and rejected alternatives incl. podFailurePolicy for ImagePullBackOff (split to #306). Closes #299 Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
Review (Fable, xhigh effort) found 3 blockers + 5 majors; all addressed: - AlreadyExists is no longer blindly benign: GET; finished/mismatched Jobs are foreground-deleted + requeued, never Upserted as in_progress - ValidateRunningPackages checks scoped to unfinished Jobs; finished Jobs cleaned only by TTL or a precise rerun predicate (protects retention) - Upgrade window: JobExists/HasRunningPackages/validation are legacy-pod aware to prevent duplicate executors and premature interrupts - not-ready/unreachable NoExecute tolerations so slow reboots don't evict the pod and fail the Job (backoffLimit: 0) - Failed (disruption) Jobs no longer write erroring: silent re-execution, keeping DeploymentPolicy failure counting unchanged - Crash-window claim corrected + stage-progress re-processing guard - Child-pod fallback for GC'd pods; package annotation on pod template - HandleConfigUpdates added to blast radius (delete Job, not child pod) - Interrupt Job name formula kept; metrics dead-code note; namespace-scoped Jobs informer; node-label length fallback; podReplacementPolicy rationale Also: TTL knobs named as chart values controllerManager.manager.env.jobTtl* Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
…ndings The load-bearing correction (CodeRabbit, confirmed against Job controller semantics): with restartPolicy: OnFailure the Job controller counts the sum of container restarts (init containers included) toward backoffLimit and terminates the pod at the limit — backoffLimit: 0 would kill a package on its first step retry. backoffLimit is now effectively unlimited (math.MaxInt32); retry ownership stays with kubelet in-place restarts, pod loss self-heals via the Job controller's replacement pod (nodeName-pinned template), and Job Failed becomes a backstop-only branch. Also, from CodeRabbit + a second adversarial review pass: - AlreadyExists must never delete a Complete-but-unrecorded Job (requeue; JobReconcile owns unprocessed completions) - child pods selected by batch.kubernetes.io/controller-uid, not job-name - containerName GC-fallback defined (interrupt label determines it) - Failed-path marker/TTL write specified; node-NotFound completion handling - postcondition guard now enumerates the interrupt/ProgressSkipped case - HasRunningPackages defined over unfinished Jobs (pod-based reading would stall interrupts behind retained Succeeded pods for the TTL window) - fourth legacy accommodation: HandleConfigUpdates keeps direct deletion of legacy erroring pods during the upgrade window - orphaned-node sweep covers Jobs of deleted nodes regardless of status - uninstall retention carve-outs documented; podReplacementPolicy gate-off wording honest; generation-label note fixed; in-flight hyphenation Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
… log-tail snapshot Enhancement over today's model (per review discussion): a stage that runs past its deadline — hung, crash-looping, or unpullable — is failed and surfaced instead of churning or hanging invisibly forever. - New additive SCR field Package.stageTimeout (metav1.Duration, follows gracefulShutdown pattern) -> Job activeDeadlineSeconds; operator default JOB_STAGE_TIMEOUT (1h, chart controllerManager.manager.env.jobStageTimeout), "0" disables. The one CRD change in the migration; additive, no shim. - DeadlineExceeded is a first-class failure: state -> erroring (new signal for hung stages; DeploymentPolicy sees stuck nodes), Job parked as the marker that stops recreation until rerun/reset/config-update or JOB_TTL_FAILED expiry (deliberate slow-retry cadence). Rules 2/3 gain the park exception; other Failed reasons stay the silent backstop. - Log-tail snapshot: on FailureTarget (pods still terminating) the operator captures the stuck container's last ~16KiB via the pod-logs API into the skyhook.nvidia.com/last-logs Job annotation, so the parked tombstone stays debuggable after the deadline deletes the pod. Best-effort, never blocks the park path. Needs pods/log get RBAC + a client-go clientset seam in dal. - Honest caveat retained: full post-deadline container logs live in SKYHOOK_LOG_DIR host logs / log aggregation. - Rejected alternative documented: restartPolicy Never + small backoffLimit (retains failed pods but can't catch hangs, changes retry substrate).

Second deliberate enhancement: skyhook.nvidia.com/pause now halts in-flight stages instead of letting them finish. UpdatePauseStatus sets spec.suspend on the Skyhook's unfinished Jobs (annotation stays the user-facing primitive; suspension is enforcement). SIGTERM mid-step is the same recovery shape as reboot/eviction — agent flag files skip completed steps on resume. Suspension clears/resets Job startTime, so the stage deadline stops ticking while paused and resets fresh on resume — closing the bad interaction where a paused-but-running stage could hit its deadline and park as erroring. Suspended Jobs stay unfinished for JobExists/validation; interrupts that already fired a reboot converge via the resource-id flag; legacy pods keep let-finish semantics during the upgrade window (CLI docs must note the version-dependent strength). disable is unchanged. Replaces the earlier 'Rejected: suspend as pause primitive' section — the no-checkpointing cost is now accepted deliberately. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
…attempt archive Reworks the retry substrate (maintainer direction + review pass 3): - Package/stage Jobs: restartPolicy Never — each attempt is a fresh pod; the operator prunes Failed pods keeping ONE full-log archive (newest Failed without DisruptionTarget, by creationTimestamp; normal deletion only). kubectl logs on the last real failure works during retries, past the deadline, and through a pause — superseding the 16KiB snapshot for genuinely-failing stages (snapshot remains for hangs and never-started containers, now also recording Waiting reason+message, e.g. ImagePullBackOff + registry error). - podFailurePolicy Ignore-on-DisruptionTarget: evictions/preemption/PodGC count nothing and stay silent. backoffLimit stays MaxInt32 (counts Failed pods under Never). - INTERRUPT Jobs keep OnFailure (no podFailurePolicy): a reboot interrupt kills its own pod by design; Never would mint a spurious failed attempt per successful reboot. - Erroring evidence guards: no DisruptionTarget, real terminal verdict (skip ContainerStatusUnknown + admission rejections), and DeletionTimestamp unset — pause suspension, rule deletions, sweeps and manual pod deletes stay silent (review pass 3 blocker). - Resume half of the pause cascade gets an explicit owner and ordering (after ValidateRunningPackages; invalidate stale suspended Jobs first). - New rule 5: REAPPLY_ON_REBOOT reset sweeps the node's Jobs regardless of status — pre-reboot completions must not land on reset state. - Honest deltas documented: hard-crash 137/Error can flap erroring once; admission-rejected pods count attempts (replaces a worse latent wedge where such a raw pod satisfies PodExists forever); attempts figure now job.status.failed (user-visible nodeState/CLI improvement); deadline on an unreachable node surfaces via stale FailureTarget as erroring; stageTimeout "0" omits activeDeadlineSeconds; HandleConfigUpdates scoped to unfinished/parked Jobs; Complete path reads the Succeeded pod.

Address maintainer review (@lockwobr): the substance was approved but the layering buried it. Restructure without cutting the analysis: - add a TL;DR decision table up top so the shape reads in 60 seconds - describe behavior by role in the narrative; move Go symbols and file references to a baseline section and a new References block - drop exact constants and most inline cross-references from the prose - collapse the defensive material (crash-window guards, hard-crash deltas, admission edge, erroring guards, pruner safety) into an 'Edge cases and correctness arguments' appendix - collapse Rejected alternatives to a table, keeping only the central Never-vs-OnFailure decision in full Also fixes the meta-lint failure: the Goals list had a duplicate '4.'

…ct (#300) (#313) * refactor(operator): package annotation helpers accept any client.Object GetPackage/SetPackages/InvalidatePackage/IsInvalidPackage only ever touch an object's annotations, but were typed to *corev1.Pod. Widen them to client.Object (using GetAnnotations/SetAnnotations instead of the .Annotations field) so the same package metadata can ride on batch/v1 Jobs and their pod templates — the first step of the package-execution-as-Jobs migration (#223). No behavior change: every call site passes a *corev1.Pod, which already satisfies client.Object. Adds a round-trip spec proving SetPackages -> GetPackage (and the invalidate path) behaves identically on a *batchv1.Job and a *corev1.Pod. Part of #300. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * refactor(operator): use metav1.Object for package annotation helpers Address review on #313: - Widen to metav1.Object instead of client.Object. The Job pod template (*corev1.PodTemplateSpec) satisfies metav1.Object but not client.Object (it has no runtime.Object methods), and the Job builder (#301) sets the package annotation on job.Spec.Template. metav1.Object is also the more precise seam, since these helpers only ever touch metadata. - Extract the repeated "<prefix>/package" key into a named constant. - Add a round-trip spec covering the Job pod template. Part of #300. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * test(operator): assert package fields and guard typed-nil in helpers Address the follow-up review on #313: - Guard the metadata helpers against typed-nil interface values. Widening from *corev1.Pod to metav1.Object weakened the original nil check — obj == nil misses a (*corev1.Pod)(nil) and would panic in GetAnnotations. A small isNil helper (reflect-based) catches both a nil interface and a typed-nil pointer; used by all four helpers. Adds a spec proving a typed-nil object is treated as absent. - The round-trip spec now asserts Version/Image/ContainerSHA against the source package, not just cross-resource equality, so a serialization regression is caught. Part of #300. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): guard nil package in InvalidatePackage/IsInvalidPackage GetPackage returns (nil, nil) when the package annotation is absent, so pkg.Invalid = true and return pkg.Invalid would panic for an object without package metadata. Now that these helpers accept any metav1.Object (and Job handling will call them on Jobs), guard nil: InvalidatePackage no-ops and IsInvalidPackage reports false. Adds a regression spec for unannotated objects. Addresses CodeRabbit review on #313.

Each wraps the pod the operator builds today (createPodFromPackage / createInterruptPodForPackage) so the executor shape can't drift, then applies the Job differences: the forever pause container becomes an exit-0 container so the pod can reach Succeeded; package Jobs use restartPolicy Never + effectively-unlimited backoffLimit + podFailurePolicy Ignore-on-DisruptionTarget (disruptions stay silent); interrupt Jobs keep OnFailure with no podFailurePolicy; podReplacementPolicy Failed; ttlSecondsAfterFinished unset at creation; unbounded not-ready/unreachable NoExecute tolerations; labels name/package/stage/node/generation (+interrupt) on the Job and its pod template, full resource-id as an annotation, node label hashed for long names. - CRD: additive Package.stageTimeout (*metav1.Duration) -> Job activeDeadlineSeconds (package value else JOB_STAGE_TIMEOUT default; 0 omits the deadline). Added to the legacy source and regenerated into the nodewright group; webhook validation (non-negative); conversion + zero-value-guard fixture; chart CRD mirror. - Options: JOB_TTL_SUCCEEDED (1h) / JOB_TTL_FAILED (24h) / JOB_STAGE_TIMEOUT (1h) with Validate() floors (TTLs >= 1m, stage timeout >= 0). - Extracted pauseContainerName/interruptLabelValue/shellBinary constants (goconst). No prod behavior change; the field/options/builders are consumed starting in #303. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): round up stage deadline; add admission and edge tests Adversarial review follow-up on #301: - activeDeadlineSeconds now rounds up via math.Ceil. A positive sub-second stageTimeout (e.g. 500ms, reachable since the webhook only rejects < 0) truncated with int64(d.Seconds()) to 0 — and activeDeadlineSeconds: 0 insta-fails every Job, so the package could never complete. Any positive timeout now yields at least a 1s deadline. - Tests: sub-second stageTimeout (=> 1s); gracefulShutdown + imagePullSecret carry-through to the pod template; interrupt Job activeDeadlineSeconds; and an envtest that Creates both Job kinds against the apiserver, validating the podFailurePolicy x restartPolicy x podReplacementPolicy x activeDeadlineSeconds field combinations that struct-level tests can't see admission for. The reviewer's second flag (Never + MaxInt32 vs the design's OnFailure/backoffLimit:0) was a false positive: that quotes the superseded pre-rework model. This implements the final approved design (Never + failed-attempt archive + Ignore-on-DisruptionTarget). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * chore(chart): mirror stageTimeout into the nodewright CRD The rebased fix/api-rename base now ships chart/templates/nodewright-crd.yaml (the nodewright.nvidia.com CRD chart mirror). The package stageTimeout field added in this series must appear there too, alongside the existing mirror into chart/templates/skyhook-crd.yaml. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * refactor(operator): author new API fields in the nodewright group only (#301) The nodewright group was a schema-frozen textual-rename mirror of the legacy skyhook types (gen_nodewright.sh), so new fields had to be added to the deprecated skyhook API and mirrored across. That guard only has value during the rename bridge; the skyhook group is removed next release. Retire the mirror so new API surface lands on nodewright only (review: lockwobr on #316): - delete scripts/gen_nodewright.sh; drop generate-nodewright from the manifests/generate prereqs and remove the generate-nodewright and verify-nodewright-gen make targets; - un-generate the nodewright group (drop the gen_nodewright DO-NOT-EDIT markers from its 5 source files; deepcopy and CRDs stay controller-gen-owned); - remove Package.stageTimeout from the legacy skyhook API (types, webhook, webhook test, conversion + its test, skyhook CRD, chart skyhook-crd.yaml) and keep it native in the nodewright API. job_builder.go already reads the nodewright field, so no behavior change.

Each wraps the pod the operator builds today (createPodFromPackage / createInterruptPodForPackage) so the executor shape can't drift, then applies the Job differences: the forever pause container becomes an exit-0 container so the pod can reach Succeeded; package Jobs use restartPolicy Never + effectively-unlimited backoffLimit + podFailurePolicy Ignore-on-DisruptionTarget (disruptions stay silent); interrupt Jobs keep OnFailure with no podFailurePolicy; podReplacementPolicy Failed; ttlSecondsAfterFinished unset at creation; unbounded not-ready/unreachable NoExecute tolerations; labels name/package/stage/node/generation (+interrupt) on the Job and its pod template, full resource-id as an annotation, node label hashed for long names. - CRD: additive Package.stageTimeout (*metav1.Duration) -> Job activeDeadlineSeconds (package value else JOB_STAGE_TIMEOUT default; 0 omits the deadline). Added to the legacy source and regenerated into the nodewright group; webhook validation (non-negative); conversion + zero-value-guard fixture; chart CRD mirror. - Options: JOB_TTL_SUCCEEDED (1h) / JOB_TTL_FAILED (24h) / JOB_STAGE_TIMEOUT (1h) with Validate() floors (TTLs >= 1m, stage timeout >= 0). - Extracted pauseContainerName/interruptLabelValue/shellBinary constants (goconst).

A positive sub-second stageTimeout (e.g. 500ms, reachable since the webhook only rejects < 0) truncated with int64(d.Seconds()) to 0 — and activeDeadlineSeconds: 0 insta-fails every Job, so the package could never complete. Any positive timeout now yields at least a 1s deadline. - Tests: sub-second stageTimeout (=> 1s); gracefulShutdown + imagePullSecret carry-through to the pod template; interrupt Job activeDeadlineSeconds; and an envtest that Creates both Job kinds against the apiserver, validating the podFailurePolicy x restartPolicy x podReplacementPolicy x activeDeadlineSeconds field combinations that struct-level tests can't see admission for. The reviewer's second flag (Never + MaxInt32 vs the design's OnFailure/backoffLimit:0) was a false positive: that quotes the superseded pre-rework model.

That guard only has value during the rename bridge; the skyhook group is removed next release. Retire the mirror so new API surface lands on nodewright only (review: lockwobr on #316): - delete scripts/gen_nodewright.sh; drop generate-nodewright from the manifests/generate prereqs and remove the generate-nodewright and verify-nodewright-gen make targets; - un-generate the nodewright group (drop the gen_nodewright DO-NOT-EDIT markers from its 5 source files; deepcopy and CRDs stay controller-gen-owned); - remove Package.stageTimeout from the legacy skyhook API (types, webhook, webhook test, conversion + its test, skyhook CRD, chart skyhook-crd.yaml) and keep it native in the nodewright API. job_builder.go already reads the nodewright field, so no behavior change.

Each wraps the pod the operator builds today (createPodFromPackage / createInterruptPodForPackage) so the executor shape can't drift, then applies the Job differences: the forever pause container becomes an exit-0 container so the pod can reach Succeeded; package Jobs use restartPolicy Never + effectively-unlimited backoffLimit + podFailurePolicy Ignore-on-DisruptionTarget (disruptions stay silent); interrupt Jobs keep OnFailure with no podFailurePolicy; podReplacementPolicy Failed; ttlSecondsAfterFinished unset at creation; unbounded not-ready/unreachable NoExecute tolerations; labels name/package/stage/node/generation (+interrupt) on the Job and its pod template, full resource-id as an annotation, node label hashed for long names. - CRD: additive Package.stageTimeout (*metav1.Duration) -> Job activeDeadlineSeconds (package value else JOB_STAGE_TIMEOUT default; 0 omits the deadline). Added to the legacy source and regenerated into the nodewright group; webhook validation (non-negative); conversion + zero-value-guard fixture; chart CRD mirror. - Options: JOB_TTL_SUCCEEDED (1h) / JOB_TTL_FAILED (24h) / JOB_STAGE_TIMEOUT (1h) with Validate() floors (TTLs >= 1m, stage timeout >= 0). - Extracted pauseContainerName/interruptLabelValue/shellBinary constants (goconst).

Any positive timeout now yields at least a 1s deadline. - Tests: sub-second stageTimeout (=> 1s); gracefulShutdown + imagePullSecret carry-through to the pod template; interrupt Job activeDeadlineSeconds; and an envtest that Creates both Job kinds against the apiserver, validating the podFailurePolicy x restartPolicy x podReplacementPolicy x activeDeadlineSeconds field combinations that struct-level tests can't see admission for. The reviewer's second flag (Never + MaxInt32 vs the design's OnFailure/backoffLimit:0) was a false positive: that quotes the superseded pre-rework model.

Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * docs(design): switch package Jobs to restartPolicy Never with failed-attempt archive Reworks the retry substrate (maintainer direction + review pass 3): - Package/stage Jobs: restartPolicy Never — each attempt is a fresh pod; the operator prunes Failed pods keeping ONE full-log archive (newest Failed without DisruptionTarget, by creationTimestamp; normal deletion only). kubectl logs on the last real failure works during retries, past the deadline, and through a pause — superseding the 16KiB snapshot for genuinely-failing stages (snapshot remains for hangs and never-started containers, now also recording Waiting reason+message, e.g. ImagePullBackOff + registry error). - podFailurePolicy Ignore-on-DisruptionTarget: evictions/preemption/PodGC count nothing and stay silent. backoffLimit stays MaxInt32 (counts Failed pods under Never). - INTERRUPT Jobs keep OnFailure (no podFailurePolicy): a reboot interrupt kills its own pod by design; Never would mint a spurious failed attempt per successful reboot. - Erroring evidence guards: no DisruptionTarget, real terminal verdict (skip ContainerStatusUnknown + admission rejections), and DeletionTimestamp unset — pause suspension, rule deletions, sweeps and manual pod deletes stay silent (review pass 3 blocker). - Resume half of the pause cascade gets an explicit owner and ordering (after ValidateRunningPackages; invalidate stale suspended Jobs first). - New rule 5: REAPPLY_ON_REBOOT reset sweeps the node's Jobs regardless of status — pre-reboot completions must not land on reset state. - Honest deltas documented: hard-crash 137/Error can flap erroring once; admission-rejected pods count attempts (replaces a worse latent wedge where such a raw pod satisfies PodExists forever); attempts figure now job.status.failed (user-visible nodeState/CLI improvement); deadline on an unreachable node surfaces via stale FailureTarget as erroring; stageTimeout "0" omits activeDeadlineSeconds; HandleConfigUpdates scoped to unfinished/parked Jobs; Complete path reads the Succeeded pod. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * docs(design): restructure Jobs migration doc for readability Address maintainer review (@lockwobr): the substance was approved but the layering buried it. Restructure without cutting the analysis: - add a TL;DR decision table up top so the shape reads in 60 seconds - describe behavior by role in the narrative; move Go symbols and file references to a baseline section and a new References block - drop exact constants and most inline cross-references from the prose - collapse the defensive material (crash-window guards, hard-crash deltas, admission edge, erroring guards, pruner safety) into an 'Edge cases and correctness arguments' appendix - collapse Rejected alternatives to a table, keeping only the central Never-vs-OnFailure decision in full Also fixes the meta-lint failure: the Goals list had a duplicate '4.' (MD029/ol-prefix); it is now sequential 1-5. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * refactor(operator): package annotation helpers accept any client.Object GetPackage/SetPackages/InvalidatePackage/IsInvalidPackage only ever touch an object's annotations, but were typed to *corev1.Pod. Widen them to client.Object (using GetAnnotations/SetAnnotations instead of the .Annotations field) so the same package metadata can ride on batch/v1 Jobs and their pod templates — the first step of the package-execution-as-Jobs migration (#223). No behavior change: every call site passes a *corev1.Pod, which already satisfies client.Object. Adds a round-trip spec proving SetPackages -> GetPackage (and the invalidate path) behaves identically on a *batchv1.Job and a *corev1.Pod. Part of #300. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * refactor(operator): use metav1.Object for package annotation helpers Address review on #313: - Widen to metav1.Object instead of client.Object. The Job pod template (*corev1.PodTemplateSpec) satisfies metav1.Object but not client.Object (it has no runtime.Object methods), and the Job builder (#301) sets the package annotation on job.Spec.Template. metav1.Object is also the more precise seam, since these helpers only ever touch metadata. - Extract the repeated "<prefix>/package" key into a named constant. - Add a round-trip spec covering the Job pod template. Part of #300. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * test(operator): assert package fields and guard typed-nil in helpers Address the follow-up review on #313: - Guard the metadata helpers against typed-nil interface values. Widening from *corev1.Pod to metav1.Object weakened the original nil check — obj == nil misses a (*corev1.Pod)(nil) and would panic in GetAnnotations. A small isNil helper (reflect-based) catches both a nil interface and a typed-nil pointer; used by all four helpers. Adds a spec proving a typed-nil object is treated as absent. - The round-trip spec now asserts Version/Image/ContainerSHA against the source package, not just cross-resource equality, so a serialization regression is caught. Part of #300. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): guard nil package in InvalidatePackage/IsInvalidPackage GetPackage returns (nil, nil) when the package annotation is absent, so pkg.Invalid = true and return pkg.Invalid would panic for an object without package metadata. Now that these helpers accept any metav1.Object (and Job handling will call them on Jobs), guard nil: InvalidatePackage no-ops and IsInvalidPackage reports false. Adds a regression spec for unannotated objects. Addresses CodeRabbit review on #313. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * docs(operator): recast em-dashes in package annotation comments Repo prose style prefers colon/comma over em-dashes in doc comments (review on #313). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * feat(operator): add Job builders and stage-timeout/TTL options (#301) Adds the batch/v1 Job builders for the package-execution-as-Jobs migration, not yet wired into reconcile (ApplyPackage/Interrupt still create raw pods until #303). - job_builder.go: createJobFromPackage / createInterruptJobFromPackage. Each wraps the pod the operator builds today (createPodFromPackage / createInterruptPodForPackage) so the executor shape can't drift, then applies the Job differences: the forever pause container becomes an exit-0 container so the pod can reach Succeeded; package Jobs use restartPolicy Never + effectively-unlimited backoffLimit + podFailurePolicy Ignore-on-DisruptionTarget (disruptions stay silent); interrupt Jobs keep OnFailure with no podFailurePolicy; podReplacementPolicy Failed; ttlSecondsAfterFinished unset at creation; unbounded not-ready/unreachable NoExecute tolerations; labels name/package/stage/node/generation (+interrupt) on the Job and its pod template, full resource-id as an annotation, node label hashed for long names. - CRD: additive Package.stageTimeout (*metav1.Duration) -> Job activeDeadlineSeconds (package value else JOB_STAGE_TIMEOUT default; 0 omits the deadline). Added to the legacy source and regenerated into the nodewright group; webhook validation (non-negative); conversion + zero-value-guard fixture; chart CRD mirror. - Options: JOB_TTL_SUCCEEDED (1h) / JOB_TTL_FAILED (24h) / JOB_STAGE_TIMEOUT (1h) with Validate() floors (TTLs >= 1m, stage timeout >= 0). - Extracted pauseContainerName/interruptLabelValue/shellBinary constants (goconst). No prod behavior change; the field/options/builders are consumed starting in #303. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): round up stage deadline; add admission and edge tests Adversarial review follow-up on #301: - activeDeadlineSeconds now rounds up via math.Ceil. A positive sub-second stageTimeout (e.g. 500ms, reachable since the webhook only rejects < 0) truncated with int64(d.Seconds()) to 0 — and activeDeadlineSeconds: 0 insta-fails every Job, so the package could never complete. Any positive timeout now yields at least a 1s deadline. - Tests: sub-second stageTimeout (=> 1s); gracefulShutdown + imagePullSecret carry-through to the pod template; interrupt Job activeDeadlineSeconds; and an envtest that Creates both Job kinds against the apiserver, validating the podFailurePolicy x restartPolicy x podReplacementPolicy x activeDeadlineSeconds field combinations that struct-level tests can't see admission for. The reviewer's second flag (Never + MaxInt32 vs the design's OnFailure/backoffLimit:0) was a false positive: that quotes the superseded pre-rework model. This implements the final approved design (Never + failed-attempt archive + Ignore-on-DisruptionTarget). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * chore(chart): mirror stageTimeout into the nodewright CRD The rebased fix/api-rename base now ships chart/templates/nodewright-crd.yaml (the nodewright.nvidia.com CRD chart mirror). The package stageTimeout field added in this series must appear there too, alongside the existing mirror into chart/templates/skyhook-crd.yaml. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * refactor(operator): author new API fields in the nodewright group only (#301) The nodewright group was a schema-frozen textual-rename mirror of the legacy skyhook types (gen_nodewright.sh), so new fields had to be added to the deprecated skyhook API and mirrored across. That guard only has value during the rename bridge; the skyhook group is removed next release. Retire the mirror so new API surface lands on nodewright only (review: lockwobr on #316): - delete scripts/gen_nodewright.sh; drop generate-nodewright from the manifests/generate prereqs and remove the generate-nodewright and verify-nodewright-gen make targets; - un-generate the nodewright group (drop the gen_nodewright DO-NOT-EDIT markers from its 5 source files; deepcopy and CRDs stay controller-gen-owned); - remove Package.stageTimeout from the legacy skyhook API (types, webhook, webhook test, conversion + its test, skyhook CRD, chart skyhook-crd.yaml) and keep it native in the nodewright API. job_builder.go already reads the nodewright field, so no behavior change. Also recast em-dashes in job_builder.go doc comments per repo prose style. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * test(operator): set Job TTL options in the legacy-workload migration test The Job builders (#301) add JobTTLSucceeded/JobTTLFailed validation to SkyhookOperatorOptions; the legacy-workload migration test (from the rename) must set them or NewSkyhookReconciler rejects the options. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * feat(operator): dal Job accessors and Job event mapper (#302) First increment of the Job-controller work for the package-execution-as-Jobs migration. Not wired into reconcile yet. - dal: GetJob / GetJobs mirroring GetPod / GetPods (+ regenerated DAL mock). - job_controller.go: jobHandlerFunc maps Job events into the single reconcile queue as "job---<name>" requests (mirrors podHandlerFunc's "pod---<name>" routing), gated on the skyhook name label so only Jobs we own are enqueued. JobReconcile / jobMatchesPackage and the pod-log-tail accessor land next. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * docs(operator): recast em-dashes in jobHandlerFunc comment Repo prose style prefers commas over em-dashes in doc comments (review on #313). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * feat(operator): jobMatchesPackage staleness check (#302) Adds jobMatchesPackage, the Job analogue of podMatchesPackage: does an existing stage Job still match what the operator would build for this package+stage now? Later increments use it to decide, on an AlreadyExists race or a validation sweep, whether a Job is stale and must be replaced. Still unwired. The Job builder wraps the raw pod without changing its initContainers or the package label — the only things podMatchesPackage compares — so this reuses podMatchesPackage on the Job's pod template rather than duplicating (and risking drift in) the env-filtering / resource comparison. Next increment: JobReconcile (completion recording + state-recorded marker + outcome TTL + DeadlineExceeded/park + failed-attempt pruner + FailureTarget log-tail snapshot) and dal.GetPodLogTail. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): guard init-container count in podMatchesPackage; harden jobMatchesPackage tests Address CodeRabbit + adversarial review on #319: - podMatchesPackage indexed expectedPod.Spec.InitContainers[i] by the actual chain's length, so an extra actual init container panicked and a missing one silently matched. Add a length check before the compare — this fixes both the pod and the Job path (jobMatchesPackage delegates here). - jobMatchesPackage specs: add a negative interrupt case (drifted version), an image-change case (package label matches but the init-copy image differs), and an init-container count-mismatch case (extra + missing, must return false without panicking). Vary the arbitrary argEncode/stage the still-unwired interrupt builder receives, and note that init-container Args are intentionally not part of the match. - Tighten the jobMatchesPackage doc comment: podMatchesPackage also branches on the interrupt label and compares init-container resources, not just the label. Part of #302. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * docs(operator): recast em-dashes in jobMatchesPackage comments Repo prose style prefers colon/comma over em-dashes in doc comments (review on #313). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): guard podMatchesPackage against init-container count drift The compare loop walks the actual pod's init containers while indexing the expected slice, so an actual pod carrying more init containers than the operator builds panics with an index-out-of-range. podMatchesPackage runs on real cluster pods from the raw-pod path (skyhook_controller.go), and no RecoverPanic is configured, so an admission webhook injecting an init container takes the manager down rather than failing one reconcile. The same missing check let the opposite case pass silently: a pod with a container missing was never compared on it and matched. Compare lengths first, which covers both. The panic is what the "does not match (and does not panic) when the init-container count differs" spec was written for; it was failing. Also move jobMatchesPackage next to podMatchesPackage in job_builder.go, with its specs beside the podMatchesPackage ones, rather than reviving job_controller.go. That file was deleted when Job events moved onto the global delay handler, and the base merge resolved the delete/modify conflict by restoring it whole, bringing back jobHandlerFunc and its "job---" routing alongside the globalDelayHandler case that replaced it.

…il (#302 part 2b) (#348) * feat(operator): JobReconcile completion recording and dal.GetPodLogTail (#302) Second increment of #302 (part 2b), stacked on #319. Adds the completion/ failure authority for the Jobs execution path plus the pod-log tail it needs. Deliberately NOT wired into reconcile yet (no Job watch, no job--- routing, no new RBAC) — the swap lands in #303 — so there is no prod behavior change. dal.GetPodLogTail: client-go clientset-backed pod-log tail (the controller-runtime client cannot read log subresources), threaded via dal.New -> NewSkyhookReconciler -> cmd/manager/main.go and mocked. The read is a thin clientset call plus a pure tailAndSanitize helper (bounded memory, true tail, valid UTF-8) under a 10s timeout so a slow/unreachable kubelet cannot stall the single reconcile pass. JobReconcile: invalid->foreground-delete; Complete->record node state once (guarded so a re-served event after a crash between the node write and the state-recorded marker cannot lose, duplicate, or regress a stage) + success TTL; Failed/DeadlineExceeded ->erroring + park + failure TTL; Failed/other->backstop marker, no state write; FailureTarget->best-effort last-logs snapshot, stale-on-unreachable-node erroring, and requeue-until-stale. The failed-attempt pruner keeps two archives - the first genuine failure (likely root cause) and the most recent - excluding disruption casualties. Verification: controller suite 236/236, dal tests, make lint 0 issues, gofmt clean. Adversarial review (opus) found no blockers; its findings (bounded log context, FailureTarget requeue, pkg-nil logging, interrupt guard) are folded in. Docs: design doc updated for the two-archive pruner. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): retry stale-FailureTarget erroring write on error (#302) handleActiveJob logged and swallowed a failed recordStaleFailureTarget, so on an unreachable node — which emits no further Job events — the erroring evidence was deferred to the next informer resync. Return the error instead so it escapes to the work queue for a backoff retry, per the repo's error-escape convention. Adds a test that forces the node patch to fail and asserts JobReconcile surfaces the error. Addresses CodeRabbit review on #348. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * docs(operator): recast em-dashes in JobReconcile/dal comments Repo prose style prefers colon/semicolon/comma over em-dashes in doc comments (review on #313).

Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): bound the log tail server-side and requeue only the grace left GetLogs streamed the whole container log and tailAndSanitize discarded all but the tail locally. Paired with podLogStreamTimeout that inverts the feature: a stage that ran to its deadline producing steady output times out and yields no snapshot at all, so the evidence is lost in exactly the case it exists for. Bound it with TailLines, not LimitBytes, which reads from the start and would return the head; tailAndSanitize still applies the byte cap. handleActiveJob requeued a fresh full failureTargetGrace no matter how much of the window had already elapsed, so a Job four minutes into a five-minute window waited another five before its stale check re-fired. Requeue the remainder, with a second of slack so the wake-up lands past the boundary instead of a hair short and burning another window. Also wrap the two bare errors in recordStaleFailureTarget and split their conditions, which conflated a lookup failure with an absent object. The design doc said the snapshot "retries once when the Job goes terminal", contradicting its own paragraph four sentences earlier: deadline expiry deletes the pod the logs live on, so there is nothing left to read once the Job is terminal. Replaced with the real behavior and the cost of missing the window.

#350) * feat(operator): swap package/interrupt execution to Jobs (#303 part 1) Wire the reconcile path to create batch/v1 Jobs instead of raw pods for package and interrupt stage execution. All Job machinery landed in #300-#302 (builders, JobReconcile, dal accessors, log tail) but was unwired; this is the cutover. - ApplyPackage/Interrupt build Jobs (createJobFromPackage / createInterruptJobFromPackage), stamp the package annotation on both the Job and its pod template (setJobPackage), gate creation on JobExists, and resolve AlreadyExists against the deterministic name via handleExistingJob. - JobExists is the migration-window union: an unfinished Job OR a pre-upgrade raw pod (legacyPodExists), so a single call gates both worlds. The !jobFinished filter is load-bearing: retained (TTL) finished Jobs must not read as running, unlike pods which were reaped on completion. - HasRunningPackages spans Jobs + legacy pods. ValidateRunningPackages becomes an orphan sweep: shouldDeleteFinishedJob rerun predicate, jobIsStale -> InvalidPackage, validateLegacyPods. TrackReboots sweeps node Jobs after Reset. - pod_controller dual-path: Job-owned pods route to jobPodReconcile (surfaces in-flight erroring only; JobReconcile owns completion), legacy pods keep the delete-on-complete path. podFailureIsGenuine skips disruption/unknown noise. - main.go registers a namespace-scoped Job informer. RBAC (batch/jobs, pods/log) mirrored into config/rbac and chart/templates. The user-facing contract is unchanged: same labels, nodeState annotations, metrics, CRD, and CLI. Behavioral mechanics are documented in the design doc. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): run the Job exit-0 container on the package image (#303) The swap's `done` container (which replaces the forever-running pause container so the pod can reach Succeeded) ran `/bin/sh -c "exit 0"` on the agent image. A minimal agent image (e.g. the agentless test image on arm64) has no /bin/sh, so the container StartErrors (exit 128), the pod never succeeds, the Job never completes, and the skyhook hangs in_progress forever. Use the package image instead: the init-copy container already invokes /bin/sh from it, so the package image is guaranteed to have a shell, and it is already pulled (no new image). Verified end-to-end on a local kind cluster (arm64, agentless): the package Jobs now complete and the skyhook reaches complete. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * feat(operator): give package-stage Jobs their own controller Jobs were wired as a prefixed "job---<name>" request on the Skyhook queue, mirroring the pod path. That shape exists to serialize writers, not because it fits: JobReconcile is already per-object and returns a per-object Result, so routing it through the whole-world pass means folding a per-Job requeue and a per-Job backoff into a queue that has neither. JobReconciler now owns Jobs on its own watch, with the name-label gate as a predicate so foreign Jobs (a CronJob's, say) never enter the workqueue rather than being filtered inside Reconcile. That removes the serialization the unlocked node patches were relying on. Two controllers now write nodewright.nvidia.com/nodeState_<name>, one annotation key holding every package, so an unconditional patch would silently drop whichever write landed second and the state-recorded marker would stop anything retrying it. Both Job-path writes go through patchNodeState: read, mutate, patch under an optimistic-lock precondition, retry on conflict. The guards moved inside the retry closure, since a retry starts from state another writer just changed and a decision made against the previous read is not reusable. The heavy pass gets the precondition on its node patches too, where a conflict escapes to the existing error aggregate: it cannot retry in place because the snapshot it computed from is stale, so the pass requeues and re-derives. TrackReboots is deliberately left unlocked, with a comment saying why. Its spec requires the reset to land on a node whose resourceVersion moved under other controllers, because losing it strands a stale "complete" and the package is never reapplied. Drops the Job case from globalDelayHandler.relevant: a Job event no longer needs to wake the heavy pass, since the node write JobReconcile makes is itself a Node event the existing watch already picks up. Signed-off-by: Brian Lockwood <lockwobr@gmail.com> * refactor(operator): drop the pod-to-Job migration window The dual path guarded an upgrade landing while raw package pods were still mid-flight. That state is unreachable: the rename has never shipped (no released operator carries the nodewright API group at all), the swap ships with it, and NodeWright reconcile is gated behind legacyMigrationHold, which holds on any legacy Skyhook whose status is not empty/complete/paused/disabled and tells the operator to finish, roll back, or delete it on the pre-rename operator first. Nothing raw can be running by the time the Jobs path takes over. So this removes validateLegacyPods, legacyPodExists, the legacy branch of the interrupt gate, and the legacy pod deletion in the config-update path. PodReconcile collapses to what was the Job-owned branch: the watch now only surfaces in-flight erroring, and never deletes a pod or records completion, both of which would race JobReconcile for the same node-state key. isJobOwnedPod and HandleInvalidPackage lose their last callers with it; the Job path covers invalidation through IsInvalidPackage plus a foreground delete. Known gap, deliberately not re-covered: the hold skips paused and disabled legacy Skyhooks, and pre-rename pause did not suspend an in-flight pod, so a Skyhook paused mid-stage could still have one running at takeover. Narrow enough not to justify keeping two execution paths alive for a release. Signed-off-by: Brian Lockwood <lockwobr@gmail.com> * test(e2e): move chainsaw assertions onto the Jobs execution model Package pods are owned by their Job now, not by the CR directly, so every assert naming NodeWright as the pod's owner fails against this branch. Those seven files were staged in the e2e PR two steps down the chain, which left #350 and #351 red in between and made a real regression indistinguishable from the expected breakage. They are a consequence of this change, so they belong with it. Also drops a restarts > 0 check that only held when a failed step restarted in place; package Jobs run restartPolicy Never, so a retry is a fresh pod. Adds assert_jobs.yaml for the half nothing covered: assert_pods.yaml proves pod -> Job, this proves Job -> NodeWright as a controller reference, which is what makes the whole tree GC with the CR. It also pins the run-to-completion defaults the pod assert cannot see (unlimited backoff, podReplacementPolicy Failed, restartPolicy Never, and the 1h JOB_STAGE_TIMEOUT default). Signed-off-by: Brian Lockwood <lockwobr@gmail.com> * fix(operator): scope Jobs and pod-log RBAC to the operator namespace Cluster-wide grants the operator never exercises. Every Job it touches lives in its own namespace: the informer is scoped there in main.go, and all six GetJobs calls pass client.InNamespace. Pod logs are only ever read off those Jobs' child pods for the deadline snapshot. The namespace= field on the kubebuilder rbac markers moves both onto a Role. kustomize's namespace transformer rewrites the literal, and the chart templates .Release.Namespace, so nothing is pinned to the default install namespace. The RoleBinding is hand-written because controller-gen generates roles but never bindings. pods/status stays cluster-wide despite sharing a generated rule with pods/log: drain reads workload pods on any node. Raised by review on the chart RBAC; the design doc said the role stays cluster-scoped, which is no longer true. Signed-off-by: Brian Lockwood <lockwobr@gmail.com> * fix(operator): stop optimistic-locking the heavy pass's node writes The precondition added with JobReconciler turned every concurrent write into a conflict the pass could not recover from. It patches every node from one whole-world snapshot, so a conflict cannot be retried in place: the state the patch was computed from is already stale, and the pass just re-runs and re-conflicts. e2e went from 0 conflicts to 156 on a single lifecycle run, and three suites (config-skyhook, cleanup-pods, interrupt) stalled with node state pinned at in_progress and the log full of "error processing skyhook". JobReconciler keeps its own lock and retry, which does converge because a single object can be re-read cheaply. That leaves the write race one-sided: the pass can still overwrite a completion that landed between its read and its patch. Closing it properly means narrowing what the pass patches, not gating a snapshot it cannot recompute, and that is its own change. Also drops the pod-finalization suite. It hand-created a raw pod and asserted the Pod watch drove node state to complete, which was the legacy path; under Jobs the operator owns node placement, so a hand-built executor cannot be attributed to a node without pinning one, and a nodeSelector leaves the Job template's nodeName empty. Nineteen other suites assert a package reaching complete through real operator-driven rollouts, and the JobReconcile unit specs cover the recording path directly. Signed-off-by: Brian Lockwood <lockwobr@gmail.com> * fix(operator): stop the pod watch from resurrecting node state The pod watch recorded in-flight erroring unconditionally, so it could create a node-state entry the operator never wrote. Under restartPolicy Never a failing Job mints a fresh pod per attempt indefinitely, which turns that into a repeating write with two failure modes: - After a node-state reset, the next attempt re-pins the package to the stage the reset just cleared. jobIsStale then reads the Job as matching node state, so the sweep never invalidates it and JobExists gates the package forever: the reset can never take effect. This is the cleanup-pods e2e failure. - A pod for a package absent from the spec writes an entry for a package that was never applied, polluting node state and flipping the Skyhook to erroring. This is the interrupt e2e failure, which HandleInvalidPackage used to mask by deleting the pod. Guard the write the way JobReconcile's shouldRecordCompletion and recordJobErroring already are: record only when the entry is present, still at this pod's stage, and not already complete. The pod watch is evidence, not authority. Finish the controller split started for Jobs: - The pod watch becomes a real controller (PodReconciler) instead of a pod---<name> request routed through the heavy pass, so it gets a real requeue and its own backoff. - Both per-object controllers hold their own dependencies rather than embedding SkyhookReconciler. Embedding inherited a Reconcile each had to shadow, so deleting the shadow would still compile and silently run the whole-world pass on every pod or Job event. - patchNodeState and deleteJobForeground become free functions, the only two helpers with callers on both sides. - The Job env knobs group into JobOperatorOptions, embedded in SkyhookOperatorOptions so field promotion leaves the builder chain and Validate untouched, and the env names stay flat. Leaving the heavy pass's single-threaded queue means the pod watch no longer serializes against it, so its node-state write now goes through the optimistic-locked patchNodeState like the Job path. That retry re-reads the Node uncached from attempt 1 onward: dal reads through the cached client, and the informer has usually not seen the write that just beat us, so a cached re-read rebuilds the same doomed precondition and burns every attempt. Attempt 0 stays cached, so the hot path costs nothing extra. Narrow the cache and RBAC to the operator namespace for the kinds that never leave it. ConfigMaps and Secrets join Jobs: all ConfigMap access already passes InNamespace and a package's spec.configMap is mounted by the kubelet rather than read, and the only Secret is the operator's own webhook serving cert. Cache scope and RBAC scope have to move together, since a cluster-wide informer under a namespaced Role is rejected at LIST/WATCH — which is why webhookBootstrapMgr, a second manager that owns the only Secret watch, gets its own scoped cache here. Pods stay cluster-wide: drain must see workload pods on any node, and scoping them would report a node drained while workloads still run. The reasoning for every kind, scoped or not, is recorded at the cache options. Removes the unreachable StateComplete half of UpdateNodeState, and corrects three comments that described a legacy raw-pod path deleted with the migration window. Signed-off-by: Brian Lockwood <lockwobr@gmail.com> * fix(e2e): drop the unsatisfiable conditions filter from cleanup-pods The precondition assert added for the reset check also required bb's config Job to be unfinished: status: (conditions[?type == 'Complete' && status == 'True']): [] An active Job has no status.conditions field at all, so that filter evaluates to null rather than an empty list and the assert can never pass while the Job is running — it failed with "Invalid value: null: value is null" against a Job that was present and correct. Existence is the whole precondition the assert needs: the step above already waits for the Skyhook to report erroring, so this Job cannot have completed. Drop the status clause and note why a conditions filter does not belong here. Signed-off-by: Brian Lockwood <lockwobr@gmail.com> * revert(operator): leave the ConfigMap cache and RBAC cluster-wide Scoping the ConfigMap informer to the operator namespace correlated with intermittent apply-to-config stalls in e2e/core: simple-update-skyhook and simple-skyhook timed out with a package parked at apply/in_progress, on a different k8s version each run. No mechanism has been identified — every ConfigMap access site passes client.InNamespace and a package's spec.configMap is a kubelet-resolved mount rather than an operator read — so this backs the change out as a single-variable bisect rather than as a diagnosis. Cache scope and RBAC scope move together: a cluster-wide informer under a namespaced Role is rejected at LIST/WATCH, so the kubebuilder marker and the chart mirror revert with it. Jobs and Secrets stay scoped. Secrets are not exercised by e2e at all (make run sets ENABLE_WEBHOOKS=false, so the manager owning the only Secret watch never starts), and Jobs have been scoped since c274004, well before these failures appeared. The reasoning for re-scoping ConfigMaps later is kept at the cache options so the memory win is not lost, with a note not to re-apply it without a reproduction first.

* feat(operator): cascade pause to Job suspension (#303 part 2) Give the Emergency Stop teeth: while a Skyhook is paused, set spec.suspend=true on all of its unfinished Jobs so the Job controller SIGTERMs the running pod and starts nothing until resume; clear it on resume. Before this, pause only blocked new stage scheduling and an in-flight stage ran to completion. - suspendUnfinishedJobs runs in the paused branch; resumeSuspendedJobs runs in the non-paused branch AFTER validateAndUpsertSkyhookData. The ordering is load-bearing: validation invalidates any Job whose spec changed while paused (returning update=true, which early-returns the loop), so resume only clears suspend on survivors. Clearing first could launch one stale-spec attempt. - The shared worker skips finished Jobs (Suspended is not terminal, so an unfinished suspended Job still gates existence and never records completion), invalid Jobs (mid-reap), and Jobs already at the desired suspend state. - The stage deadline pauses with the Job: suspension clears the Job start time, so activeDeadlineSeconds stops ticking and a resumed stage gets a full timeout (native Job behavior, no code). - Legacy raw pods can't suspend; pause keeps let-finish semantics for them until the migration window closes. docs/cli.md notes the version-dependent stop strength. Node state stays in_progress across a suspend: the killed pod carries a DeletionTimestamp, so erroring-evidence guard (c) keeps pod evidence silent. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): merge-patch spec.suspend, and cover the cascade in e2e Two review findings from #351. Patch spec.suspend instead of Updating the Job. The Jobs come from a cached list, and the Job controller rewrites Job status constantly — flipping suspend itself deletes the pod and produces more status writes — so a full Update carries a resourceVersion that is already stale and 409s for no reason. No optimistic lock: the operator is the only writer of spec.suspend and sets an absolute value rather than a read-modify-write, so last-write- wins is correct here. Same tradeoff the Node patches document in TrackReboots. Add the pause-suspends-jobs e2e test. The unit specs cover which Jobs get spec.suspend set, but they run against a fake client where nothing acts on the field, so every behaviour the feature actually promises was untested: suspension SIGTERMing the pod, node state holding at in_progress, and resume starting a fresh pod that re-runs the stage. The assertion worth the most is that pausing does not mark packages erroring. A pod deleted by suspension is indistinguishable from a failed attempt to the pod watch; only PodReconcile's DeletionTimestamp guard separates them, and nothing else exercises it. Without that guard every pause would record its packages as failures and count them against DeploymentPolicy budgets. Signed-off-by: Brian Lockwood <lockwobr@gmail.com> * fix(e2e): correct the pause-suspends-jobs fixture and precondition Two defects found by running the test rather than only linting it. The package version is the agentless image tag, and 1.0.0 is not published, so the pod sat in ImagePullBackOff. Use 1.2.3, which shared-cordon-slow already runs with SLEEP_LEN. The precondition asserted status.phase: Running, which that pod can never reach while the stage is in flight. Package work runs in init containers, so the pod stays Pending for the whole stage and only reaches Running once apply has finished — the opposite of the state this test needs. It burned the full assert timeout waiting. Assert instead that exactly one init container is running. Init containers execute sequentially, so that means a step is genuinely executing, which is what keeps the post-pause negative assertion from passing vacuously against a pod that never started. Verified against a kind cluster: passes in 12s, and the erroring check observes node state holding at stage=apply state=in_progress across the suspension. Signed-off-by: Brian Lockwood <lockwobr@gmail.com> * fix(e2e): poll for the executing stage instead of asserting it The precondition assert failed in CI after 400ms on a single attempt, despite a 240s assert timeout: CREATE at 20:41:56.233, ASSERT ERROR at 20:41:56.640. The operator has to reconcile before any pod exists, and on a CI node that just finished another test that is not instant — so the assert had nothing to match. It passed locally only because a warm empty cluster produced the pod before chainsaw's first poll. Use a bounded polling script, the same shape as the event poll in delete-blocked-when-paused. A resource assert carrying a status expression has nothing to evaluate against an empty match, and rather than depend on exactly which chainsaw semantic bites here, polling is correct either way and prints the Jobs and pods on timeout instead of failing bare. Local runs cannot reproduce the CI timing, so this is verified as no-regression locally; the two k8s versions that failed are the real check.

…lk (#387) `dag.Next(complete...)` could permanently stop offering a package that had no `dependsOn` and had not finished yet. `leaves()` returned nil as soon as the completed set was larger than the number of dependency-free vertices, and the fallback walked outward from the completed set. That walk only ever reaches children of completed vertices, and a dependency-free vertex is nobody's child, so once it was skipped it could never be offered again. `RunNext()` then returned a list without it, `ApplyPackage` was never called for it, and the package parked at its last recorded stage forever. The NodeWright stayed `in_progress` with no error, no event and no condition. Reproduced in e2e/core as an intermittent apply-to-config stall in `simple-update-skyhook`, which has three dependency-free packages out of five: whichever dependency-free package happened to finish last was stranded once the other four completed. Whether that happens depends on which stage Job finishes last, which is why it looked like flake and moved between Kubernetes versions. Replace both branches of `Next` with a single scan for "not in `from`, and every parent in `from`". That is the definition the existing specs already encode step for step, and it cannot lose a vertex because it never depends on reachability from the completed set. Also fill in `parents` when a placeholder vertex is promoted. A vertex named by a child before it was added kept an empty parent set, so the parent check passed vacuously and it could run ahead of its dependencies. `BuildGraph` ranges a Go map, so the add order is re-randomised on every reconcile and the promotion happens at random. The new `Next` consults `parents` on every vertex rather than only on walked children, so this had to be correct. Both defects predate the Jobs migration; the graph code is unchanged on main.

#390) Part of #223. Mirrors the LEGACY_CLEANUP_DELAY precedent so JOB_TTL_SUCCEEDED, JOB_TTL_FAILED, and JOB_STAGE_TIMEOUT (introduced as envconfig-only defaults in #316) are configurable instead of requiring a hand-edited Deployment. - operator/config/manager/manager.yaml: add the three env entries, kustomize defaults matching the envconfig defaults (1h/24h/1h) - chart/templates/deployment.yaml: add matching env entries reading from .Values.controllerManager.manager.env - chart/values.yaml: add jobTtlSucceeded/jobTtlFailed/jobStageTimeout values (1h/24h/1h) with doc comments No Go changes -- the envconfig fields already existed on JobOperatorOptions. JOB_BACKOFF_LIMIT is not wired since backoffLimit is still hardcoded (#373 not yet landed). Verified: helm lint clean, helm template renders all four values correctly, no duplicate env entries.

#316 set the stage deadline on JobSpec.ActiveDeadlineSeconds, which is terminal: exceeding it fails the Job permanently with no replacement pod, so the first expiry parked. That made a timeout the one failure class with no retry. Move the bound to the pod template so an expired attempt is Failed and replaced like any other failure, and give up on a finite backoffLimit instead of math.MaxInt32. No operator-side retry counter to persist. Package Jobs now carry three bounds: spec.template.spec.activeDeadlineSeconds = stageTimeout (per attempt) spec.backoffLimit = JOB_BACKOFF_LIMIT (default 3) spec.activeDeadlineSeconds = derived ceiling The ceiling is (backoffLimit+1) * (stageTimeout + gracefulShutdown + 10m), clamped to MaxInt32. It exists only for the case a per-attempt clock cannot bound: that clock runs from pod.Status.StartTime, which a pod the kubelet never acknowledges never gets. gracefulShutdown is in the formula because podReplacementPolicy Failed waits out every shutdown; without it a slow shutdown could truncate the retry budget into a DeadlineExceeded that reads as a hang. Deriving it rather than adding a fourth knob makes a ceiling below the retry budget unrepresentable. Interrupt Jobs are deliberately unchanged. Under OnFailure backoffLimit counts container restarts, so a finite budget would be spent by the in-place restart that is the reboot recovery, and the bound must span the reboot, which a per-attempt clock cannot. The park signal inverts, as #373 anticipated: BackoffLimitExceeded becomes the park and DeadlineExceeded becomes a routine retry. Two consequences that were not in the issue and are worth review attention: - BackoffLimitExceeded alone is not sufficient to park. These pods carry spec.nodeName rather than going through the scheduler, so kubelet admission is the only gate they face; a node at capacity or returning from a reboot can reject several node-pinned replacements in a row, each Failed with no container statuses and no DisruptionTarget for the Ignore rule to match. At MaxInt32 that cost an archive slot; at 3 it exhausts the budget in ~70s and would park a package that never ran a line of script. Terminal failure is now believed only when a retained archive really failed. The Job-level ceiling needs no such evidence. - pod_controller.go could not stay untouched. A pod killed by its own deadline whose container never started (unpullable image, missing configmap - the hang the deadline exists for) has no exit code, and podFailureIsGenuine rejects both shapes it can take. The Pod watch now also keys on the pod-level DeadlineExceeded reason, which nothing else sets; without it a hang would read in_progress for the whole retry budget, worse than the single deadline this replaces. Also: shouldDeleteFinishedJob now requires the state-recorded marker for Failed Jobs, not just Complete. A finite backoffLimit takes a Job from first failure to terminal in about a minute, so the sweep would otherwise race the erroring write into a fresh, equally doomed attempt. Behavior note for the changelog: backoffLimit bounds every failure class, not just timeouts. A crash-looping package parks after 4 attempts (~70s) where it previously retried for the whole stageTimeout (~1h, ~10 attempts). Packages that ride out transient environment flakiness lose that hour of self-healing, which is why the limit is an operator knob rather than a constant. Default stays 3 per the issue. Docs: stageTimeout docstring and both CRD copies, the design doc's Job shape / retry / stage-deadline / pause / finished-Job-rules / rejected- alternatives sections and its stale skyhook_types.go path, and the erroring row in operator-status-definitions.md (it now also means "gave up"). Chart and kustomize both carry JOB_BACKOFF_LIMIT. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
…-expiry text CodeRabbit review on #402, both findings valid: - backoffLimit: 3 permits one initial attempt plus three retries. Four comments described it as the attempt count; say retries and spell out backoffLimit+1 total attempts. - The Log visibility section still described deadline expiry as deleting the running pod. That is now only true of the Job-level ceiling; a per-attempt expiry terminates the containers and marks the pod Failed with reason DeadlineExceeded in place, so the attempt survives as an ordinary archive with its logs. Distinguish the two and keep the snapshot rationale, which the ceiling case still needs. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
CodeRabbit review on #402. The comments conflated two decisions the code deliberately keeps apart: backoffLimit counts Failed pods, but exhausting it only takes the Job terminal — the stage parks as erroring solely when a retained attempt genuinely failed. A Failed pod falls into one of three classes: an ignored disruption spends nothing; an attempt the kubelet refused to admit spends an attempt without being the package's failure; a genuine step failure or per-attempt timeout spends an attempt and is. Only the third parks. Say so in the options docstring, manager.yaml, values.yaml, and the design doc's backoffLimit paragraph, which still claimed only genuine failures could count at all.

CodeRabbit review on #402 read jobFailureIsGenuine as the sole gate on parking and concluded that losing the archives to pod GC loses the park. It is not the sole gate, but nothing said so, so write it down. The park predicate is (terminal Failed, entry at (stage, erroring)) in both places that evaluate it. jobFailureIsGenuine only decides whether the terminal path is the one to write that entry; the Pod watch writes it live, while the archive still exists, using the same classification. Each covers the other's blind spot — the Pod watch survives archives being GC'd, the terminal path survives the operator being down through the retries. Both must miss to lose a park, and the stage then re-runs and parks on the next cycle rather than churning. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
…th too CodeRabbit review on #402. shouldDeleteFinishedJob was taught to wait for the state-recorded marker on both outcomes, but handleExistingJob — its mirror, and the path that reaches the window first — still carved out only unprocessed Complete Jobs.

Generalize the carve-out to any unprocessed finished Job so both paths reach the same verdict, and cover the ordering with specs on handleExistingJob, which had none. Also wrap the two propagated errors in handleFailedJob so a failure names whether classification or the state write broke.

UpdatePauseStatus sets spec.suspend on the Skyhook's unfinished Jobs (annotation stays the user-facing primitive; suspension is enforcement). SIGTERM mid-step is the same recovery shape as reboot/eviction — agent flag files skip completed steps on resume. Suspension clears/resets Job startTime, so the stage deadline stops ticking while paused and resets fresh on resume — closing the bad interaction where a paused-but-running stage could hit its deadline and park as erroring.

Each wraps the pod the operator builds today (createPodFromPackage / createInterruptPodForPackage) so the executor shape can't drift, then applies the Job differences: the forever pause container becomes an exit-0 container so the pod can reach Succeeded; package Jobs use restartPolicy Never + effectively-unlimited backoffLimit + podFailurePolicy Ignore-on-DisruptionTarget (disruptions stay silent); interrupt Jobs keep OnFailure with no podFailurePolicy; podReplacementPolicy Failed; ttlSecondsAfterFinished unset at creation; unbounded not-ready/unreachable NoExecute tolerations; labels name/package/stage/node/generation (+interrupt) on the Job and its pod template, full resource-id as an annotation, node label hashed for long names. - CRD: additive Package.stageTimeout (*metav1.Duration) -> Job activeDeadlineSeconds (package value else JOB_STAGE_TIMEOUT default; 0 omits the deadline). Added to the legacy source and regenerated into the nodewright group; webhook validation (non-negative); conversion + zero-value-guard fixture; chart CRD mirror. - Options: JOB_TTL_SUCCEEDED (1h) / JOB_TTL_FAILED (24h) / JOB_STAGE_TIMEOUT (1h) with Validate() floors (TTLs >= 1m, stage timeout >= 0). - Extracted pauseContainerName/interruptLabelValue/shellBinary constants (goconst).

A positive sub-second stageTimeout (e.g. 500ms, reachable since the webhook only rejects < 0) truncated with int64(d.Seconds()) to 0 — and activeDeadlineSeconds: 0 insta-fails every Job, so the package could never complete. Any positive timeout now yields at least a 1s deadline. - Tests: sub-second stageTimeout (=> 1s); gracefulShutdown + imagePullSecret carry-through to the pod template; interrupt Job activeDeadlineSeconds; and an envtest that Creates both Job kinds against the apiserver, validating the podFailurePolicy x restartPolicy x podReplacementPolicy x activeDeadlineSeconds field combinations that struct-level tests can't see admission for. The reviewer's second flag (Never + MaxInt32 vs the design's OnFailure/backoffLimit:0) was a false positive: that quotes the superseded pre-rework model.

That guard only has value during the rename bridge; the skyhook group is removed next release. Retire the mirror so new API surface lands on nodewright only (review: lockwobr on #316): - delete scripts/gen_nodewright.sh; drop generate-nodewright from the manifests/generate prereqs and remove the generate-nodewright and verify-nodewright-gen make targets; - un-generate the nodewright group (drop the gen_nodewright DO-NOT-EDIT markers from its 5 source files; deepcopy and CRDs stay controller-gen-owned); - remove Package.stageTimeout from the legacy skyhook API (types, webhook, webhook test, conversion + its test, skyhook CRD, chart skyhook-crd.yaml) and keep it native in the nodewright API. job_builder.go already reads the nodewright field, so no behavior change.

UpdatePauseStatus sets spec.suspend on the Skyhook's unfinished Jobs (annotation stays the user-facing primitive; suspension is enforcement). SIGTERM mid-step is the same recovery shape as reboot/eviction — agent flag files skip completed steps on resume. Suspension clears/resets Job startTime, so the stage deadline stops ticking while paused and resets fresh on resume — closing the bad interaction where a paused-but-running stage could hit its deadline and park as erroring. Suspended Jobs stay unfinished for JobExists/validation; interrupts that already fired a reboot converge via the resource-id flag; legacy pods keep let-finish semantics during the upgrade window (CLI docs must note the version-dependent strength). disable is unchanged.

Item 8 of #411. The page claimed the operator "relies only on core, long-stable Kubernetes APIs" and "gates on no version-specific features", and marked ~1.23-1.32 as expected to work. That stopped being true when package execution moved to batch/v1 Jobs. The Jobs path depends on podFailurePolicy, the DisruptionTarget pod condition, the FailureTarget Job condition, podReplacementPolicy, the batch.kubernetes.io/* pod labels, suspend and ttlSecondsAfterFinished. An apiserver that does not know a field drops it and returns success, so on an older cluster the operator creates a healthy-looking Job with the field absent and the property it guaranteed simply gone — no error, event, or log line, and nothing surfaces until the case that field existed to handle actually occurs. Replaces the blanket claim with a cumulative table: each row lists what newly stops working below that version, so reading top-down accumulates the losses. Splits the old 1.23-1.32 band into 1.29-1.32 (every field at least beta-on-by-default, losses theoretical) and 1.23-1.28 (real degradation). The sharpest row is below 1.26, and it got sharper with #402: without podFailurePolicy the Ignore-on-DisruptionTarget rule disappears, so evictions and preemptions count toward backoffLimit like genuine failures. At the old unbounded limit that was harmless; at a finite JOB_BACKOFF_LIMIT a couple of unrelated disruptions can park a package that never failed. Version numbers track upstream feature-gate graduation, not measured NodeWright behaviour — none of these clusters are in CI, and the table says so rather than implying a tested promise.

Review question on #421 that the row could not survive: does losing the succeeded-container-name lookup mean we stop knowing a stage completed? No, and the row implied otherwise. Completion is read from the Job's Complete condition, never from pods (job_controller.go:164). The container name it finds feeds one variable whose only use is an equality check against InterruptContainerName (job_controller.go:342), and interrupt Jobs source that from the Job's own label rather than a pod. For every other stage it is cosmetic, exactly as the comment above the call says. Listing it as a cost was wrong. The claim that failure evidence stops being retained was backwards too: losing pruneFailedAttempts means archive pods accumulate rather than being trimmed to two, which is a scale problem, not an evidence problem. The row now names the two real costs — unbounded archive accumulation, and the last-logs snapshot never firing for a container that never started — and states plainly that completion is unaffected.

Item 5a of #411, confirmed against the code. resumeSuspendedJobs is called from the reconcile loop for any Skyhook that is not paused, and the only IsDisabled guard in that flow lives in processSkyhooksPerNode, a different function further down. So clearing the pause annotation and setting disable in one edit un-suspended every Job pause had suspended: disabling a paused NodeWright restarted it. That makes disable strictly weaker than pause for in-flight work, which is the opposite of how it reads — docs/cli.md offered it as "disable completely", directly under the pause example. Disable still does not stop work already running; the design doc is explicit that it never claimed to. The fix is only that it must not RESTART work pause stopped. Re-enabling resumes them. The guard is inside resumeSuspendedJobs rather than at the call site so it holds for every caller, and because that is where the existing specs already exercise this behaviour — a call-site guard would have been untestable without standing up a whole reconcile, and this controller has no full-Reconcile spec to model one on. docs/cli.md now states the distinction rather than implying disable is the bigger hammer. Written as prose rather than a third stacked blockquote, which MD028 rejects. Spec verified to fail against the unguarded version. Refs #411 (item 5a).

CodeRabbit review on #422; all three points were right. My replacement for "disable completely" was "stop it being processed at all", which oversells it just as much. It is now "prevent new work being scheduled". NewDisableCmd still said "Disable a NodeWright completely" and "the operator will completely stop processing". Updating docs/cli.md without it left the CLI's own --help contradicting the page, which the repo requires to move together. Its long help now states that a stage already under way runs to completion, and that disable never restarts what pause stopped. The re-enable sentence was wrong, not merely vague. Reconcile hits `if skyhook.IsPaused() { ...; continue }` before resumeSuspendedJobs, so while pause is set the resume never runs regardless of disable. "Re-enabling resumes them" implied enable alone was enough; both annotations have to be cleared. The command's short help keeps the word "Disable" because lifecycle_test.go asserts each Short contains its verb — a convention worth conforming to rather than loosening the test for.

…ommodations Item 2 of #411, resolved as a docs fix now that the epic's open question has an answer: the rename and the Jobs migration ship together. The Upgrade section specified four in-place accommodations so Jobs and raw pods could run side by side for a minor release — legacy-aware completion, existence gating that ORs in raw pods, a legacy sweep in validation, and direct deletion of legacy erroring pods on config update. None were built. That was not an oversight; they were superseded by legacyMigrationHold, which takes a stricter line: it runs first in Reconcile and requeues while any pre-rename Skyhook is still rolling out, so the two execution models never overlap rather than being taught to coexist. Shipping the two together is what makes that work, and the section now says so. Had the rename landed in an earlier release, the preceding operator would already be nodewright-native, no legacy Skyhook objects would exist, the hold would never fire, and its raw pods would carry labels the legacy sweep does not select — and the accommodations really would have been required. Also records the one case the hold does not cover: it treats a paused legacy Skyhook as not-in-flight so migration does not force an unpause, but pre-Jobs pause never stopped a running pod. Unpausing such a Skyhook on the new operator before its pod finishes puts a Job alongside it on the same host copyDir. Narrow, idempotent in practice via the agent's flag files, and now written down rather than discovered later. ValidateRunningPackages claimed a legacy raw-pod sweep ran alongside its Job checks. It never did; the comment now says why it walks Jobs only. Refs #411 (item 2). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
… running Item 4 of #411, resolved as documentation. Editing stageTimeout, JOB_STAGE_TIMEOUT or JOB_BACKOFF_LIMIT changes what the next Job is built with and does not reach a Job already running. jobMatchesPackage compares only the pod-template subset podMatchesPackage looks at — labels and per-init-container name/image/env/resources — so the changed value is not staleness and nothing is replaced on the strength of it. Making it reach in-flight work is not a small fix, and Kubernetes does not offer a clean one. The per-attempt bound lives on the Job's pod template, which is immutable, so it cannot be patched — and a template edit would only reach pods created after it anyway. The running pod's own activeDeadlineSeconds is mutable but may only be DECREASED, which is backwards from the edit that motivates the change: people raise a timeout because a stage needs longer. Applying an increase means replacing the Job, which kills the in-flight attempt in order to give it more time. So the contract is stated rather than engineered around: the new value applies at the package's next stage, and to apply it to work already under way the user clears the Job — `kubectl nodewright package rerun`, or deleting it — and the stage restarts under the new value. Covers the CRD docstring (regenerated into both CRD copies), the chart's jobStageTimeout comment, and the design doc's stage-deadline section, which also records why the Job-level ceiling is left unpatched even though it alone is mutable: patching it would leave the ceiling and the per-attempt bound disagreeing.

#426) (#435) * fix(operator): never resurrect a package entry on interrupt completion An interrupt Job is package-agnostic — one per node, stage and interrupt type, deduped across packages — so its completion also has to promote siblings left at (interrupt, skipped). shouldRecordCompletion's interrupt branch authorizes the write on the strength of such a sibling, before looking at the Job's own package at all. recordJobCompletion then took that as license for its own package too: HandleCompletePod's interrupt branch only promotes and reports no update, so the fallback Upsert always ran, and Upsert creates. A rerun, reset or finalizer-driven uninstall that removed the entry while the interrupt Job was completing therefore got it back at (interrupt, complete) — and with the entry present and complete, the rerun predicate keeps the Job, so the stage never runs again. The rerun the user asked for silently does nothing until the failure TTL. The self-write is now gated on entryAwaitsCompletion (present, at this stage, not complete), extracted so shouldRecordCompletion's non-interrupt tail and this guard cannot drift. Promotion is untouched. State is re-read after HandleCompletePod, since promotion can move this package's own entry. Closes #426.

A deleted NodeWright reads as (nil, nil) from GetSkyhook, and wrapper.Convert dereferences it, so HandleCompletePod's interrupt branch panicked when the CR was removed while a completed interrupt Job was still unprocessed — the same window the entry guard is about. The uninstall branch two blocks down already nil-checks; this one now does too. Pre-existing, but it is the same failure family, and the new spec panics without the guard. The success event could also lie once the self-write is gated: an interrupt Job that reaches the recorder purely on a sibling's promotion left skyhookNode.Changed() true, so the operator announced "Package [x:1.0.0] state complete" for a package whose entry a reset had just cleared. The event now follows what was actually written. Also folds shouldRecordPodErroring onto entryAwaitsCompletion — it was a third verbatim copy of the same predicate in the same package — and notes on recordJobErroring why its erroring-exclusion is deliberately not the same helper. Specs added for the CR-gone panic, the upgrade branch's RemoveState path (previously untested), and no-regression from a later stage on the interrupt path, which is the direction only the new guard covers. The design doc now records that the create-nothing rule binds the Job path too, not just the Pod watch. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * refactor(operator): name the shared guard for its shape, not one caller Review pointed out that reusing a predicate called entryAwaitsCompletion for the Pod watch's erroring write reads as the wrong thing, which is the same complaint that renamed isParkedJob. It is now entryOpenAtStage — present, at this stage, not complete — which is what both callers actually require, with the doc comment saying so and recording why an already-erroring entry is deliberately still open (a rising restart count must land; an identical write is dropped by the Changed() check). Also tightens the no-regression spec to assert State as well as Stage, and fixes a garbled sentence in the design doc. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * test(operator): prove the no-regression spec exercised the completion path The spec seeded the entry at (post-interrupt, complete) and asserted it was still there, which a reconcile that did nothing at all would also satisfy. It now asserts the sibling was promoted and the Job carries the state-recorded marker, so the interrupt completion path demonstrably ran while the entry was left alone. Also inserts the relative pronoun the design doc sentence was missing. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> --------- Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>

…snapshot (#413) * fix(operator): merge node-state deltas instead of restamping a stale snapshot The heavy pass, JobReconciler and PodReconciler are three controllers with three workqueues, all writing nodewright.nvidia.com/nodeState_<name> — one annotation whose value is a single JSON document covering every package. Before the Job and Pod watches became their own controllers they rode the heavy pass's queue at MaxConcurrentReconciles 1 and could not interleave; splitting them removed that guarantee without replacing it. The heavy pass builds its result from a snapshot taken at cluster-state build time and then patches the whole value unconditionally. A completion recorded by JobReconcile in between is reverted to in_progress, and nothing re-records it because the Job is already marked state-recorded: the stage recovers only by being torn down and re-run. Locking the write would not have fixed it. The value is computed long before the write, so a lock just serializes a stale value into place. Instead derive the pass's delta by diffing its starting snapshot against its result, and apply only that on top of whatever the annotation holds at write time, under an optimistic lock with retry. Entries the pass never touched keep whatever another writer put there. The patch target is rebuilt from the freshly read node rather than the pass's own object, deliberately: that object predates any concurrent write, so diffing against it would emit deletions for keys another writer added since the snapshot — another NodeWright's nodeState_* among them. SkyhookReconciler gains the uncached reader NewJobReconciler already takes. Without it RetryOnConflict re-reads through the informer, rebuilds the same resourceVersion precondition that just lost, and burns every attempt — which is how the earlier optimistic-locking attempt produced a conflict storm. The regression test was verified to fail against the old overwrite behaviour before being kept. Refs #411 (item 1). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): keep spec fields and the wrapper cache out of the merge's blast radius Review of #413 found that rebuilding the patch target from the freshly read node — the step that makes the node-state merge work — quietly turned two other fields into whole-value restamps, and left the wrapper answering from a cache the merge had invalidated. spec.taints and spec.unschedulable were assigned from the pass outright on the grounds that this controller owns them. It does not: the cluster autoscaler, node-problem-detector and a human with kubectl all write taints, and hasSkyhookCordon exists precisely because two Skyhooks can hold a cordon on one node. With the fresh read as the patch base, an untouched field became an explicit write — taints are listType=atomic so the list is replaced, and Unschedulable is omitempty so false diffs as an explicit null. A pass that never touched either could delete an autoscaler taint or uncordon a node another Skyhook was draining. Both now replay only what the pass changed. skyhookNode caches a parsed copy of node state and State() serves it whenever it is non-nil, so replacing the embedded Node with the merged one left IsComplete, NextStage and UpdateCondition reading the pre-merge map. That published a NotReady/Incomplete condition for a node that had just completed and dropped its MarkComplete event. The wrapper gains InvalidateStateCache, matching the nodeState = nil precedent Reset and CleanupSCRMetadata already use, and the merge calls it. The node condition patch was still based on the pass's build-time snapshot while being applied to the post-merge object. That re-sent whatever the kubelet had changed in .status and carried the snapshot's resourceVersion into the patch body, where the apiserver reads it as a precondition — so any concurrent write turned it into a 409, and that error gates both the Skyhook's UpdateCondition and its status patch. It is now based on the post-merge object, so the diff is exactly the conditions UpdateCondition touches. The untracked-node branch returned StrategicMergeFrom against a copy of the object itself, which is an empty patch: a broken invariant would have silently dropped the write. BuildState tracks and adds a node in the same step so it is unreachable; it now says so. Also drops the duplicated node reader in favour of the existing readNodeForPatch, which is a free function for exactly this reason. Both new spec-field regressions and the cache-coherence assertion were verified to fail against the unfixed code before being kept. Refs #411 (item 1). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * test(operator): cover the conflict retry and the uncached read path These were the last untested part of the node-state merge, called out on the PR: nothing in the suite forced a conflict, so neither RetryOnConflict nor the uncached branch of readNodeForPatch ever ran. The optimistic lock is only worth anything if a conflict is retried AND the retry re-derives against a fresh read, and neither half was being checked. The first test forces a conflict on the first patch via an interceptor client (the pattern job_controller_test.go already uses) and supplies the uncached reader with a node the cached client does not have: a completion only the apiserver knows about. It then asserts the patch was retried, that exactly one uncached read happened (attempt 0 stays cached), and that the retry merged its delta onto what the uncached read returned rather than onto the stale cache. That last assertion is what makes the uncached branch load-bearing rather than an optimisation nobody would notice losing. The second covers the node being deleted between attempts, which returns nil rather than an error: a node that went away mid-pass has no state to resurrect. Both were verified against sabotaged code before being kept. Disabling the uncached branch fails both; replacing RetryOnConflict with a single call fails both. Refs #411 (item 1). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): wrap propagated errors and replay a pass-owned taint edit CodeRabbit review on #413. Three findings; one was already closed by the adversarial-review pass, two were not. Wrap the propagated errors in saveNodeChanges. Five bare `return err` values from a function that reads, merges and patches, which the coding guidelines forbid outright. The patch error is wrapped with %w deliberately: RetryOnConflict decides via apierrors.IsConflict, which unwraps, so the retry keeps working — and the conflict-retry spec added in 115d1a4 fails if that ever stops being true, which is how this was checked rather than assumed. Replay a pass-owned taint edit that a concurrent delete removed. If original and modified hold the same taint identity with different values and the fresh read no longer has it, applyTaintChanges dropped the pass's edit: the second loop only appended identities absent from original. It now appends when the pass added the taint OR changed the value of one it inherited, while an identity the pass left exactly as it found it still yields to the concurrent deletion. This one is latent rather than live: Taint() early-returns when the key is already present and RemoveTaint() only removes, so the operator has no path that edits a taint's value in place and the scenario is unreachable today. Pinned with specs on both sides of the rule so it stays closed if such a path ever appears. Also adds the untracked-node spec CodeRabbit asked for, inverted to match what that branch now does. Its suggestion — assert the node still changed — was right for the original code, which diffed the object against a copy of itself and silently dropped the write. The branch returns an error now, so the spec asserts that instead: a broken invariant must not look like success. The retry-loop half of that same finding was already covered by 115d1a4. Refs #411 (item 1). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): compare inherited taints by value, not by struct identity CodeRabbit review on #413, and a real bug in the taint fix from c4b0cfb. corev1.Taint carries TimeAdded *metav1.Time, so `originalTaint != taint` compares pointer identity, not the instant. original and modified are separate DeepCopies and DeepCopy allocates a fresh *metav1.Time, so every taint that carries TimeAdded compared as edited even when the pass never touched it — and the edit-replay branch then resurrected taints another writer had concurrently deleted. That is the exact failure mode the surrounding code exists to prevent. Key and Effect are the taint's identity, so Value is the only thing an edit can change; comparing it sidesteps the pointer entirely. TimeAdded is set by the system rather than this operator, so it has no business driving a replay decision either way. The existing specs missed it because every fixture left TimeAdded nil, where two nil pointers compare equal. The new one sets it, and fails against the struct compare. Refs #411 (item 1). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * fix(operator): re-seed the node-state cache instead of nilling it cli-e2e has failed on every commit since ff2ca87, consistently, on cli-deployment-policy-reset: the rollout stalls at progressPercent 50 with status waiting and an empty batchState. This is the cause. ff2ca87 added InvalidateStateCache, which set skyhookNode.nodeState to nil so the next State() would re-parse the merged annotation. State() does re-parse when the cache is nil — but IsComplete, NextStage, GetComplete and PackageStatus read node.nodeState DIRECTLY and never go through State(). A nil cache therefore reads as "no package has any state": a node that had just completed reported incomplete, its MarkComplete event never fired, RemoveNodePriority was never called, and skyhook.IsComplete stayed false, so the DeploymentPolicy batch never advanced past the first node. NodeState.Upsert makes it worse still — it allocates a fresh map over a nil one, so the next write on that wrapper would have dropped every other package's entry. Replaced with ReloadState, which re-parses into the cache rather than leaving it nil. That is what the review actually asked for; nilling it was my substitution and it was wrong. The unit test missed it because it asserted through State(), the one accessor that tolerates a nil cache by re-parsing. It now also asserts through PackageStatus, which reads the cache directly, and fails against the nil-cache version. Refs #411 (item 1). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * refactor(operator): diff against the snapshot, merge only the contended value Review found the justification for rebuilding the patch target from the freshly read node does not hold. A two-way strategic merge diff is computed from the snapshot and the pass's object alone, so a key present in neither -- another NodeWright's nodeState_*, a foreign label, an autoscaler taint -- cannot appear in the patch at all. The emitted body for a pass that edits one annotation and two labels is exactly: {"metadata":{"annotations":{"...nodeState_a":"..."},"labels":{"added":"1","drop":null}}} Rebuilding from the fresh read is what turned every untouched field into an explicit write, and applyPassChanges/applyMapChanges/applyTaintChanges existed only to undo that. The taint half did not fully succeed: its first loop restamped the pass's value over a taint another writer had edited, and dropped TimeAdded that the apiserver had stamped on a NoExecute taint. Both were reachable by a pass that changed no taints at all. So keep the pass's snapshot as the diff base and splice the fresh resourceVersion into it for the lock. The base serves two roles -- left-hand side of the diff, and source of the optimistic-lock precondition -- and MergeFromWithOptimisticLock reads the version from the base, so the two can be served by different objects. Only the contended annotation value is re-derived. spec.unschedulable and spec.taints then need no handling whatsoever: unchanged by the pass means absent from the diff. That removes 122 lines and both taint regressions with them. Clobbering a foreign taint when the pass DOES change a taint is pre-existing on main and is tracked in #447; the structural fix that would delete the delta machinery outright is #448. Also guards the merge on the pass having kept the annotation. Reset() deletes it outright and means it, so re-merging would resurrect the key it just wiped -- a divergence from main that the fresh-read version shared. The foreign-metadata assertions move off applyPassChanges unit specs onto the real saveNodeChanges path, where a stored node carries a foreign label, a second NodeWright's state key, an autoscaler taint and a cordon that this pass never saw. Verified to fail with the base swapped back to the fresh read. Refs #411 (item 1). Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com> * test(operator): cover the wipe guard and the divergence the sweep clears Two gaps found auditing what the node-state work actually proves. The passKeptState guard shipped without a spec. Reset() deletes the annotation outright, and a delta of pure removals would otherwise be re-marshalled and written back as "{}" -- resurrecting the key the pass just wiped and leaving a node that reads as tracked-with-no-packages rather than untracked. Verified to fail with the guard forced true. shouldDeleteFinishedJob had four cases and none of them was the one the lost update actually produces. Absent-entry was covered (a reset or an uninstall) but not an entry reverted to (this stage, in_progress), which is the regression shape: a completion clobbered back by the pass. That predicate is the reason a lost update self-heals rather than stalling, at the cost of re-running the stage, so it is worth pinning as its own case rather than inferring it from the absent-entry one.

fix(operator): never resume a disabled NodeWright's suspended Jobs
Brings the jobs branch up to main (15 commits behind, 55 ahead). Seven files conflicted; three needed a semantic resolution rather than a side pick, because main fixed code that this branch had moved or deleted. Ported forward, not dropped: - #450's semantic resource comparison. Main fixed podMatchesPackage to compare quantities with apiequality.Semantic instead of reflect.DeepEqual: apimachinery rewrites a quantity into canonical form on serialization ("4000m" -> "4"), so a pod read back is never byte-equal and reflect.DeepEqual reports a mismatch that isn't one, invalidating and recreating forever. That function moved to job_builder.go on this branch and still had the pre-fix reflect.DeepEqual, so the Jobs path carried the same bug. Taking either side of the conflict would have shipped it; the fix is now in job_builder.go where the function lives, and the now-unused apiequality import is dropped from skyhook_controller.go. - #410's skyhook -> nodewright event text. Main renamed every "[skyhook:%s]" in controller sources; this branch had added three more in job_controller.go and pod_controller.go that main could not reach. Renamed to match. - Main's "Resource Comparison" spec block. It exercises podMatchesPackage, which survives here, so it tests exactly the fix above and is kept alongside this branch's "cluster state compartments" block rather than replaced by it. Side picks, with reasons: - pod_controller.go / skyhook_controller.go ValidateRunningPackages: main edited raw-pod code this branch replaced with the Jobs path. Ours, plus the rename. - chart/templates/manager-rbac.yaml: main's #371 removed the kube-rbac-proxy Role; that deletion auto-merged elsewhere in the file and the conflicting hunk is this branch's new least-privilege namespaced Role. Ours. - strict-order chainsaw: main's script block lacks the "set -e" guard this branch added. Ours. - Both RELEASE_NOTES.md: additive bullets under the same heading describing different shipped changes. Both kept. Also repairs a textual auto-merge artifact: main added six workload_migration specs calling the 4-argument NewSkyhookReconciler, which this branch widened to six parameters (uncached reader + clientset). Updated to match. make unit-tests passes (8 suites, 333 controller specs), golangci-lint 0 issues. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
The Jobs release notes said a stage killed by its own deadline gets a last-logs snapshot. It does not, and manual validation on 2026-08-12 and again on 2026-08-13 found the annotation empty in every package-stage case: a per-attempt deadline fails the pod in place, so the archive holds the logs and snapshotFailureLogs deliberately skips. The annotation is still written for an interrupt Job's whole-stage deadline, where the Job controller deletes the pod, so the note now says that instead of promising it for every timeout. Refs #449, which tracks the fact that the fallback is currently unreachable for package Jobs at all. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>

the behavior when set to "0".
- Line 36: Update the controllerManager.manager.env.jobTtlSucceeded description
in chart/README.md at lines 36-36 to state that the success TTL does not apply
to successful explicit uninstall, which deletes its Job and pod immediately.
Update chart/RELEASE_NOTES.md at lines 17-18 to state that successful explicit
uninstall does not retain Job or pod logs.

In `@docs/designs/2026-07-10-package-execution-as-jobs.md`:
- Line 140: Update the archive-retention statement and related scale guidance to
clarify that pruneFailedAttempts caps only genuine failed child pods during
active handleActiveJob reconciliation; disruption casualties are excluded, and
terminal Jobs may retain additional failed pods if no further active reconcile
occurs.
- Around line 183-191: Update
docs/designs/2026-07-10-package-execution-as-jobs.md lines 183-191 to mark the

while preserving the existing error message and failure behavior for invalid
states.
In `@operator/internal/controller/annotations_test.go`:
- Around line 114-128: Add a test in the annotation specs for a Job whose
packageAnnotationKey value is malformed JSON, asserting that GetPackage and
IsInvalidPackage return errors and InvalidatePackage fails without panicking.
In `@operator/internal/controller/job_builder_test.go`:
- Around line 258-275: The API admission test should create Jobs in the suite’s

BuildState and ReportState omit such nodes before ValidateRunningPackages runs.
Keep the deletion behavior unchanged for any node missing from nodesByName.
In `@operator/internal/dal/dal_test.go`:
- Around line 134-210: Convert TestTailAndSanitize and TestGetPodLogTail to
Ginkgo/Gomega specs within the existing suite, replacing t.Run and t.Fatalf with

Document the explicit-uninstall retention exception consistently. Successful explicit uninstall currently deletes its Job and pod immediately, so its output is not retained for the configured success TTL. Qualify the success-retention description in the chart documentation and release notes for both chart and operator packages, or fix #443 before release.

Reuse one options helper for all three Describe blocks.
The saveNodeChanges Describe repeats the same SkyhookOperatorOptions literal twice, and saveNodeChanges conflict retry already defines an equivalent opts() helper at lines 331-341. Move that helper to package scope in this file and call it from both places. This keeps the three fixtures from drifting when a new required option is added to Validate().
Also applies to: 287-301

Scope ownedPod to the operator namespace and require both package labels.
The Pod cache is cluster-wide for node drain, so a copied nodewright.nvidia.com/name label in another namespace can enqueue this controller and drive node-state writes. Require nodewright.nvidia.com/name and nodewright.nvidia.com/package, pass options.Namespace into NewPodReconciler, and update the existing ownedPod() test call sites.

Remove the duplicated compartment spec.
The new cluster state compartments Describe repeats the spec that still exists at lines 1942-1981 inside the Resource Comparison Describe. Both specs are named should partition nodes into compartments and assert the same fixtures and expectations. The PR summary states the coverage was moved into a dedicated group, so the original occurrence should have been deleted. Delete the copy at lines 1942-1981 and keep this dedicated group.

Convert these tests to Ginkgo/Gomega.
TestTailAndSanitize and TestGetPodLogTail use stdlib t.Run and t.Fatalf. The package now owns a Ginkgo suite (dal_suite_test.go), so these cases run outside the suite's reporting and randomization. Use DescribeTable/It with Gomega matchers instead, matching the Job accessors block above.
As per coding guidelines: "Use Ginkgo/Gomega rather than stdlib t.Run".

The release notes covered the Jobs migration's features but never its upgrade story, and the one bullet #305 scoped for it asserted behavior that does not exist: in-flight legacy pods finishing under an old path for one minor. Those four accommodations were deliberately dropped in favour of legacyMigrationHold, which stops the two execution models overlapping at all — the design doc's Upgrade section already records this, so the notes were the last place still implying a dual path. Document what actually happens instead: the hold, the quiet-window prerequisite, the cordoned-and-stalled node an operator sees if they ignore it, and the one unsupported sequence the hold does not cover (unpausing a migrated NodeWright while a pre-upgrade raw pod is still live). Mirror the prerequisite into the chart notes, where helm upgrade is what the user actually runs. Also note the successful-uninstall retention carve-out (#443) next to the retention bullet it contradicts, and correct the two remaining comments — suspendUnfinishedJobs and the design doc's pause section — that still described pause's legacy behavior as a closing migration window rather than a difference across operator versions. Add a Validation section to the design doc. docs/plans/ is gitignored, so the hand-run pass behind #305 (16 Jobs cases, plus the rename pass that exercised the hold) had no committed home; the repo rule asks for the verification to be documented, and the not-covered list is part of that record. No behavior change. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>

| - **Resume has an explicit owner and ordering.** Because the pause path only runs for paused Skyhooks and paused Skyhooks skip validation, un-suspension is a separate step for *non-paused* Skyhooks, ordered after validation: invalidate suspended Jobs whose spec changed while paused, *then* clear `suspend` on the survivors. Clearing first would let one stale-spec attempt launch before validation catches it. | ||
| - **Everything else is indifferent**: existence gating counts the suspended Job, completion ignores it (Suspended is not terminal), and node state stays `in_progress` (guard (c) of the erroring evidence makes that hold). | ||
| - **Interrupts already fired**: suspension can't un-ring a reboot; on resume the replacement pod skips the interrupt via the resource-id flag and completes. | ||
| - **Legacy pods can't suspend** — a pre-rename raw pod has no Job, so pause cannot stop one. It never has to: the migration hold keeps the two execution models from running side by side (see [Upgrade and compatibility](#upgrade-and-compatibility)). What stays version-dependent is pause's stop-strength *across operator versions* — a pre-Jobs operator lets an in-flight stage finish — which is the CLI-docs note. |

Correct the migration-hold claim.
The migration hold does not guarantee that a paused or disabled legacy Skyhook has no live raw pod. operator/RELEASE_NOTES.md Lines 192-200 states that re-enabling such a resource before its raw pod exits can start a Job beside it on the same copyDir. Replace “It never has to” with the supported condition and retain the warning for this unsupported case.

Narrow the migration claim to active legacy rollouts.
legacyMigrationHold runs only in SkyhookReconciler; Pod and Job reconcilers do not create replacement execution. Paused or disabled legacy Skyhooks bypass the hold, and an existing raw pod is not suspended. Unpausing or enabling the migrated NodeWright before that pod exits can start a Job beside it. Align this comment with the documented unsupported transition and avoid claiming that the execution models can never overlap.

Resolves 12 conflicts where main's rename work (#440 chart resource names, #462 metrics rename, #452 runtime-required taint key) touched files the Jobs work also changed: - Options struct keeps both PublishLegacyMetrics and the embedded JobOperatorOptions. - Pod builders moved to job_builder.go on this branch, so main's edits to createPodFromPackage / createInterruptPodForPackage were ported there: GetRuntimeRequiredToleration -> GetRuntimeRequiredTolerations (plural). - Chart values/deployment/README/RELEASE_NOTES keep both sides' knobs. - Chainsaw metrics assertions take main's nodewright_* names, keeping this branch's set -e and TIMEOUT harness lines. - manager.yaml takes main's RUNTIME_REQUIRED_TAINT spelling (the old RUNTIME_REQUIRED_TAINT_KEY was never read) alongside the JOB_* knobs. Two test fixes the merge required: main's new legacy-taint reboot spec now wires dal (TrackReboots deletes node Jobs on this branch), and the Job admission spec creates its own namespace instead of relying on the suite's, which moved to nodewright with the namespace default.

| # | Case | Result | Evidence that it passed |
|---|---|---|---|
| 1 | single package | pass | no Job-level activeDeadlineSeconds, per-attempt 3600, backoffLimit 3, podReplacementPolicy: Failed; pods retained and logs readable after completion; ttl=3600 + state-recorded set at completion |
| 2 | multiple packages + dependsOn |
pass | 6 Jobs, exactly one per (package, stage); dexter reached config/complete on the same tick the dependents started |
| 3 | erroring, retries exhausted | pass | failed=4, BackoffLimitExceeded, ttl=86400, exactly 2 archive pods, no churn over 60s (same UID); both unpark paths — spec edit and kubectl nodewright package rerun — replaced the terminal Job |
| 4 | stage timeout | pass | attempt killed at ~21s not 600s, pod Failed/DeadlineExceeded in place with the SIGTERM readable; raising stageTimeout to 10m cleared the old Job and the new one carried 600 |
| 5 | multiple CRs on one node | pass | priority 100 held the node exclusively for 90s, then priority 200 — no tick with unfinished Jobs from both CRs; separate nodeState_ keys |
| 6 | interrupt grouping | pass | one merged interrupt Job for two packages, node cordoned during and uncordoned after; the skipped sibling promoted to complete |
| 7a | explicit uninstall | fail | #443, third consecutive reproduction — details below |
| 7b | CR deletion + full wipe | pass | finalizer ran an uninstall Job during deletion; stays entry preserved as docs/uninstall.md specifies; a CR whose only package is uninstall.enabled: true left zero nodewright.nvidia.com/* annotations |
| 8 | TTL by outcome | pass | succeeded ttl=60 collected first, failed ttl=180 still present; node state unchanged by collection; replacement Job after the failure TTL; sub-minute TTL refused at startup (job ttl succeeded must be at least 1 minute) |
| 9 | kubelet-refused attempts | pass | OutOfcpu with no container statuses, failed climbed to 4, node state stayed in_progress and never erroring; budget→sweep→recreate self-heal observed |
| 10 | pause / disable | pass | pause set spec.suspend: true and deleted the running pod; resume started a fresh one; disable-added-while-pause-removed held the Job suspended for 64s (#422 behaviour) |
| 11 | config update mid-flight | pass | in-flight config Job invalidated ~6s after the edit (new UID and new resource-id); the ConfigMap itself is not swapped until the stage completes on all nodes, then the stage re-ran and ended colour=red |
| 12 | two nodes + interruption budget | pass | never more than 1 node cordoned across the whole rollout; one interrupt Job per node |
| 13 | node deleted mid-run | pass | orphaned Job foreground-deleted 5s after the node object went away, no replacement; surviving node completed and the CR reached complete |
| 14 | disruption casualty | pass | evicted attempt (eviction subresource, so DisruptionTarget is set) left status.failed empty — no retry budget spent — and never erroring |
| 15 | upgrade → downgrade | pass | upgrade ran the upgrade stage and removed the superseded entry; downgrade keeps both entries, which docs/uninstall.md states is intentional for uninstall.enabled: false |
| 16 | unpullable image | pass | erroring at t+62s with a 60s stageTimeout — bounded, not indefinite (the #306 baseline) |
Nothing regressed under the merge: every case landed the same way as the 3e3886ea run.
New issue found and not fixed
The operator never explains a Job it deletes — no log line, no event. deleteJobForeground
(operator/internal/controller/job_controller.go:752) logs nothing at any level and records no
event, so all three delete paths are silent to an operator:
- orphaned-node sweep (case 13 — the Job was simply gone 5s later)
- stale-spec / spec-edit clear of a terminal Job (cases 3 and 4)
- config-invalidation of an in-flight Job (case 11)
The asymmetry is what makes it confusing: Job creation and stage transitions are well covered
(~296 events this run — NodeWright/State, NodeWright/Apply, Node/State, Node/Apply, plus
Job/SuccessfulCreate from the Job controller). Only deletion is unexplained, so on pager duty a
vanished Job is indistinguishable from a TTL collection or a stray kubectl delete. Across the
whole ~70-minute run the operator log contained 10 distinct messages, all controller-runtime
startup plus one benign reconcile error.
Suggested fix: one logger.Info in deleteJobForeground carrying the job name, node and a
caller-supplied reason (orphaned-node, stale-spec, config-update, timed-out-cleared).
Diagnosability only — no lifecycle impact — so P2, in the same family as #443 and #449.
Already-open findings, unchanged
- #443 (case 7a) — a successful uninstall
Job and its pod are deleted immediately, so uninstall output is unrecoverable; every sibling stage
in the same CR keptttlSecondsAfterFinished: 3600. Entry removal, CR status and the full-wipe
path were all correct. - #449 —
last-logswas absent in cases
4, 9 and 16. Case 9 (kubelet refuses every attempt, so there is no genuine archive to defer to)
was the scenario where it should have populated; it did not. That is direct evidence for the
issue's claim that the annotation never fires for package Jobs at all.

Merges the Jobs migration (#223) to
main: package stages now execute asbatch/v1Jobs instead of operator-managed raw pods. 58 commits, 85 files.The lifecycle state machine is unchanged — stages, Status/State derivation, interrupt/cordon/drain sequencing and DeploymentPolicy all behave as before. What changes is the executor, and three deliberate enhancements ride along: a per-attempt stage deadline (
stageTimeout), pause becoming a true stop, and retained failure logs. Design:docs/designs/2026-07-10-package-execution-as-jobs.md.Before merging
