feat: implement ADR-080 phase-transition events - #349
Conversation
Implement ADR-080 phase and verdict Events across Job, Workflow, Certification, and WorkloadRun. Emit only after successful status persistence, suppress same-phase updates, and retain action warnings when persistence fails. Preserve concurrent terminal Job decisions during status retries. Stage timeout and success fixtures through their real lifecycle, and cover validation errors, rejected creates, checkpoint restart, polling-message churn, and failed-write recovery. Add UID-scoped Event goldens and bounded collection, consolidate recorder test setup, and document the accepted ADR and troubleshooting guidance.

Review (ADR-080 phase-transition events)
Tip reviewed: 01a04aaf8d6dbfd2f5fa54362b6561b7780cc58c. CI green on this SHA (Test, Lint, UAT/Kind+KWOK, Build, Analyze Go, DCO, generated-files verify, etc.). No prior human reviews.
This is a careful implementation of Accepted ADR-080, not a drive-by Event sprinkle. Approving.
What lines up well
- Flip ≠
changed.conditionFlip/conditionTransitionignore reason/message/ObservedGeneration/extra-only edits; exclusive wrappers andsetJobFailedemit only when the true type changes, and only after a successful write. That is the whole point of splitting #252 from #250. - Conflict-retry correctness. Transition is cleared and recomputed inside each mutate attempt (
setExclusiveStatusConditionUnless), so a stale pre-retry flip cannot leak into an emit. WorkloadRun’ssetWorkloadRunConditionAndUpdatemirrors the same before/after rule at its direct-update seam without forcing it onto the shared helper. - Decision 5 fallbacks. Same-reason pre-write Warnings at WorkloadRun
BuildFailed, WorkflowHeterogeneousPlatform, and bothOverrideErrorsites are moved to distinct*StatusUpdateFailedreasons on failed persistence; successful paths notify only via the Failed transition. Certification’s typedworkflowCreateRejectedErrorstops the catch-all from rewritingWorkflowFailed→WorkflowValidationFailed, so Events and Conditions stay aligned. - Job verdicts + timeout hook.
HardwareFailed/ValidationFailed(including absent→FalseThresholdsMet) and the Workflow-drivenJobTimedOutwrite are hooked as specified, including emit-against-Job from the Workflow recorder and no duplicate on pod-drain re-entry. - Concurrent terminal preservation. Routing Job exclusive writes through
setExclusiveStatusConditionUnless(..., r.isTerminalState)so a conflict retry cannot replace a Workflow timeout / Succeeded winner with a stale workload observation is a real correctness win;TestJobPhaseWritePreservesConcurrentTerminalDecisionpins it (including no Event on the discarded attempt). - Harness. UID-filtered
events/v1projections, opt-inevents:blocks, cumulative deadline, and recorder-level counters for node-poll / checkpoint-restart match the ADR’s testing-method amendments. Goldens I spot-checked (rejected Create, threshold fail/pass, timeout, early override) match the promised shapes.
Residual (non-blocking)
- Branch state: tip is diverged from
main(behind_by: 1). Rebase before merge so CI re-runs on a current base. - Deferred status shape (already in ADR): timed-out Jobs still carry
InProgress=TruebesideFailed=True, and that write still uses a bareStatus().Updatewithout the shared retry helper. Fine to leave as a follow-up record; just do not treat this PR as having closed that exclusivity gap. - Coverage preference (optional):
workflow-job-timeoutwaits for WorkflowFailedbut only goldens Job Events. A sibling expect row for the Workflow terminal Warning would lock the manual Kind/KWOK sequence end-to-end; other Workflow Failed cases already cover the generic path. - Docs nit: ADR narrative still illustrates Job start as
WorkloadCreatedin several places; fixtures that enter mid-flight correctly showWorkloadRunningas the first InProgress Event. Harmless if readers treat those snippets as the create-path happy path, not as every golden’s literal first row.
No blocker findings on design fidelity, emit-after-write safety, or dedup. Thanks for the thorough recorder + envtest matrix.

Read through this closely and ran the suite locally against 01a04aa. The design is sound and most of the implementation is exactly right: transitions are computed inside the retry callback and reset per attempt, emission sits strictly after a successful write, transitionEventType takes each tier's own Failed constant so a terminal failure cannot render as Normal, no user string is ever used as a format string, and Event projections are filtered by fresh UID so a name-reusing case cannot contaminate a golden. workflowCreateRejectedError also fixes a real status bug: on the base branch the generic catch-all rewrote the persisted reason from WorkflowFailed to WorkflowValidationFailed.
Two things I would like resolved before this merges, one I would like soon after, and a few follow-ups.
Blocking
-
docs/operations/troubleshooting.md:25-27promises a verdict Event that most runs never emit.checkPerformanceThresholdsreturns atjob_controller.go:738-740whenlen(job.Spec.Thresholds) == 0, andreasonThresholdsMethas exactly one non-test write site,job_controller.go:793, inside that function. Both callers go through the same early return, so no other path can emit it. Only thecommunication/nccl-*catalog entries setthresholds:;training/nemotron5-*anddiagnostics/dcgm-level4set none, as does any hand-written Job or WorkloadRun. That makes this the common case rather than an edge case. The sentence needs a no-thresholds clause. -
ADR-080 does not describe the
stop/isTerminalStateguard, and this commit flips the record toAccepted. To be clear about which way this cuts: the guard is correct and it is load-bearing. I reverted both Job call sites to plainsetExclusiveStatusConditionand it emits an Event in 4 of the 6 combinations thatTestJobPhaseWritePreservesConcurrentTerminalDecisioncovers, including aWarning WorkloadFailedon a Job the Workflow had already givenWarning JobTimedOut. The ADR's flip-detection premise at:149-152does not hold at this seam, because the timeout write is additive and leavesJobInProgress=True, sotrueConditionTyperesolves the before-type toInProgressand the retry does see a flip. The problem is only that the record says the opposite::435is "Keepchangedand its semantics" and:445-447sayssetJobFailedkeeps itsextraclosure "unchanged; only the post-write emission is added". Please add a paragraph covering the guard and its two consequences:changedno longer implies a landed write, andrecordJobStatustherefore leavesnvcre_job_statusatin_progress=1for a timed-out Job permanently, since the series is only removed on Job deletion and timed-out Jobs are kept for the report.
Strong should-fix, fine as an immediate follow-up
- Event notes over 1024 bytes are rejected outright by the API server, so no Event object is created at all. I reproduced it end to end through the real controller path: patching
job-trainjob-fail's TrainJob failure message to 1116 characters producesServer rejected event (will not retry!) ... message: Invalid value: "": can have at most 1024 characters, and the case then fails on missing Events. client-go performs no truncation (tools/events/event_recorder.go:66and:110pass the note through verbatim) and does not retry. The class predates this PR and its worst instance is already onmain, which is why I am not making it a gate. But this PR now routes persisted condition messages into notes at all four tiers, while CRDconditions[].messageallows 32768 characters, and it adds a new length-scaling site atworkflow_controller.go:2482-2486. One truncation helper in the sharedeventfwrappers covers it. Worth noting that six reconcilers callRecorder.Eventf, not four:goodputmeasurement_controller.go:1523andbandwidthmeasurement_controller.go:566bypass the transition wrappers.
Follow-ups, not gates
-
The new
workloadrun-event-successcase is timing-flaky. It failed 2 of 8 runs under-raceontimed out waiting for condition Succeeded on WorkloadRun/event-success-run, and passed 16 of 16 without. See the inline note for the root cause, which is a pre-existing race this PR makes operator-visible. -
job-bandwidth-threshold-passswappingbandwidthMeasurement.minBusBandwidthGBpsforthresholds.busBandwidthGBpsdrops the only integration coverage of the legacyminBusBandwidthGBpsfield. Worth restoring somewhere. -
The transient "existing Workflow is being deleted; retrying" path at
certification_controller.go:585-602produces 0 Events onccc8991and 1Warning WorkflowValidationFailedhere. The code is byte-identical to the base and the underlying misclassification (a retry path that writesFailed=True) is pre-existing, so this PR only makes it audible. Worth a separate issue rather than a change here. -
Optional test additions: a
stop: truecase in the transition golden, since the input schema already has aconflictWinnerknob; and asserting message and count in the event readiness gate atintegration_test.go:1171-1172, which currently keys only on{type, reason}.
One small correction to my own earlier read, in case it came up elsewhere: moving the HeterogeneousPlatform and OverrideError Warnings post-write does not remove a per-requeue re-emission. On the base branch that Warning already fired exactly once, because the following setWorkflowFailed succeeds and reconcileJob short-circuits on isTerminal. What the move actually buys is that the Warning no longer claims a Failed phase before the write that would persist it. Still worth doing, just for a different reason.

Re-review (tip 606059f)
Prior APPROVE was on 01a04aa. Tip moved through 2a09b58 (ndipebot findings) → 57305ed (Event-collection determinism) → 606059f (merge main). CI green on this SHA. Re-checked the prior gaps; approving again.
Prior gaps — closed
-
Troubleshooting Event overclaim.
docs/operations/troubleshooting.mdnow statesWorkloadCompletedis unconditional, and thatThresholdsMet/ validation-failure Events exist only when thresholds are configured. Matches the no-threshold goldens. -
ADR
stop/isTerminalStaterecord. ADR-080 Implementation now documentssetExclusiveStatusConditionUnless: refreshed-object guard before mutation,changed=false/ no transition when Succeeded or Failed is already True, skippedextraon the discarded attempt, and the consequence thatchangedis not proof a write landed. Status staysAcceptedwith the shipped behavior described rather than contradicted. -
Testing-plan amendment for
verifyNodePollEvents. Dedup bullet now records the recorder-count exception for the time-dependent countdown message, parallel to the checkpoint-restart amendment. -
Event-note 1024-byte cap.
formatEventNotetruncates with UTF-8 safety and... [truncated]; all six recorder wrappers (Job,Workflow,Certification,WorkloadRun,Goodput,Bandwidth) route through it with a literal"%s". Unit boundary + envtest persistence coverage present. Troubleshooting documents the limit and points operators at status conditions for the full message. -
workloadrun-event-successflake. Fixture now starts from persistedInProgress+ an existing Succeeded Workflow and goldens onlyNormal/WorkflowSucceeded. Production informer-ordering race remains #352 — correct split. -
Harness determinism (
57305ed). Event projection sort key includesCount; API ops inside the cumulative Event budget use the deadline-derived context (waits, deletion, frozen-goodput, spec-immutability, final collect).
What still looks right
Emit-after-successful-write, flip ≠ reason/message churn, conflict-retry recomputation, Job terminal preservation via Unless, and Decision 5 fallbacks are unchanged in substance from 01a04aa and still hold on this tip.
Residual (non-blocking, unchanged)
- #352 still owns the production
WorkflowDeletedmisclassification on informer lag; this PR correctly hardens the fixture without pretending to fix the controller path. - Timed-out Jobs can still carry
InProgress=TruebesideFailed=True(additive Workflow timeout write). Exclusivity repair remains a separate follow-up, as previously noted. - CodeRabbit’s “recover Workflow after status write fails” path is pre-existing / tracked (#354 per author); not introduced here.
No remaining blocker from the prior COMMENT set. Thanks for the precise follow-ups.
There was a problem hiding this comment.
formatEventNote is correct on the byte boundary: I confirmed against an envtest apiserver that a 1024-byte note is accepted and 1025 is rejected, and that reverting the six call sites reproduces the original rejection on the node-shortfall path. The wrote = false pin is real too: deleting that line now fails four subcases of TestJobPhaseWritePreservesConcurrentTerminalDecision, and restoring the pre-review test file makes the same mutation green again. On the dedup bullet, removing the guard at pkg/controller/status.go:221 fails certification-event-progress with expected 1, actual 5, so the ADR text now describes something that exists.
Build and merge hygiene are clean at 606059f: go build, go vet, the full ./pkg/..., ./test/... and ./cmd/... suites with envtest, -race, -shuffle=on, make manifests generate a no-op, and the main merge byte-identical to ccc8991..d90b5ff.
Three of the inline comments below I would like resolved before this goes in: the waitForDeletion deadline hole, the WorkloadRun coverage gap, and the workloadrun-mpi behavior under -race. The remaining two are low priority.

Normal / WorkflowSucceededfrom a pre-persisted InProgress + existing Succeeded Workflow; fake-client recorder test is explicitly not a substitute for Reconcile / API-level creation coverage. Release prerequisite text matches the author note (do not ship ADR-080 without #352). -
workloadrun-mpirace exposure.initializeWorkloadRun: trueruns initial reconcile on the direct API client before the manager cache starts; golden asserts only terminalWarning / WorkflowFailedand does not acceptWorkflowDeleted. -

WorkloadCreated. -

Still holds from earlier reviews
Emit-after-successful-write, flip ≠ reason/message churn, conflict-retry recomputation inside Unless, Job terminal preservation (wrote = false / skipped extra), Decision 5 fallbacks, and the 1024-byte note cap across all six recorder wrappers remain intact on this tip.

Went through the round-2 fixes the same way, by reverting each one and checking whether anything actually fails. All seven are addressed and five are properly pinned. readObject and getObject in particular are clean: swallowing the error again fails TestReadObjectPreservesErrors, removing the ctx.Err() pre-check fails it too, and deleting the NotFound arm takes down 30 integration cases. The workloadrun-mpi flake is genuinely fixed rather than relocated, 15/15 clean against 2/10 at 606059f, and running the first reconcile before startManager is the right shape. I also checked that the per-tier requirement at docs/designs/080-phase-transition-events.md:625-626 is byte-identical to the old :618-619, so nothing was weakened to fit, and the #352 gap and release gate are recorded honestly.
Worth saying plainly: measured against main, this PR is net-additive on coverage. Executed cases go 767 to 773 across cmd/integration and pkg/controller, six pure additions and zero removals.
What I am raising below is not leftover review comments. It is three things the fix commit itself introduced, one of which is in the same function my last comment was about. Only the first is blocking for me.
Verified at b8ae291: go build ./..., go vet, and ./pkg/controller/ all clean after the main merge, which touched none of the implementation files.
Normalize invalid UTF-8 before applying the Event note byte limit and verify persistence through the API server. Avoid fatal assertions in polling goroutines and reject unknown fixture kinds before polling. Clarify ADR examples and explicitly require restoration of WorkloadRun WorkflowCreated coverage with NVIDIA#352 before release. Signed-off-by: Kayne Tu <kaynet@nvidia.com>

Emit-after-successful-write, flip ≠ reason/message churn, conflict-retry recomputation inside Unless, Job terminal preservation (wrote = false / skipped extra), Decision 5 fallbacks, and the 1,024-byte note path across all six recorder wrappers are unchanged in substance from b8ae291.
Main merges since then (#360–#364) are deps / release / Fern register and do not touch the ADR-080 controller seams.
Residual (non-blocking, unchanged)
- #352 still owns production
WorkflowDeletedmisclassification and WorkloadRun creation-to-success Event coverage restoration. - Timed-out Jobs can still carry
InProgress=TruebesideFailed=True. - Pre-existing Workflow-recover-after-status-write-fails path remains #354.
No blocker from the b8ae291 COMMENT set or the 258af6f follow-ups. Approving on tip 893880c.

Summary
Implement ADR-080 so
kubectl describeshows lifecycle transitions for Certification, Workflow, Job, and WorkloadRun. InProgress and Succeeded transitions emit Normal Events; Failed transitions emit Warnings. Events use the persisted condition's reason and message, emit only after successful status writes, and suppress repeated phases and reason/message-only updates.Add separate Job hardware and validation verdict Events, including
ThresholdsMet, and the Workflow-drivenJobTimedOutEvent on the Job. Preserve concurrent terminal Job decisions during status retries. Keep action-failure diagnostics when status persistence fails, and preserve Certification's specificWorkflowFailedreason after rejected Workflow creation.Add UID-scoped Event integration goldens, a bounded collection deadline, and recorder-level coverage for retries, failed writes, fallback warnings, polling-message changes, and checkpoint restart. Mark the ADR accepted and document operator-facing Event semantics. Measurement reconcilers retain their action warnings; their outcomes are reported through Job verdicts, as specified by ADR-080.

Type of Change
Component(s) Affected
Testing
Validation:
make manifests generate,make lint-fix,make ci, andgit diff --check.The automated suite covers successful and failed lifecycle transitions, hardware and threshold verdicts, timeout/pod-drain re-entry, rejected Workflow creation, status-write failures and conflict retries, fallback recovery, checkpoint restart, and changing polling messages. Event goldens assert API persistence; recorder assertions count emissions before API aggregation.
Manual Kind + KWOK validation on this implementation:
OverrideErrorand one WorkloadRunWorkflowFailedWarning.JobTimedOut, one WorkflowIterationsFailed, and one WorkloadRunWorkflowFailedWarning.KWOK simulates workload completion; these checks validate lifecycle propagation and Events, not GPU execution or performance measurements. The full catalog UAT suite was not run for this controller change.
Risk Assessment
OverrideNoOpand transientWorkloadCreationErrorwarnings can still appear during successful runs; they are separate from transition deduplication.Checklist
