the delete reactor’s purpose if needed, using plain ASCII.

- Around line 519-521: Update the termination flow around evictInstances to
return immediately when eviction fails, preventing ICMSRequest deletion and
success reporting; preserve the existing warning while propagating the error. In
evictInstances, return malformed status.instances errors with %w instead of
converting them to nil, and add regressions covering forbidden Pod deletion and
invalid status.instances data.
- Around line 604-605: Update the merge loop over terminated records to preserve
the latest map already in existing: retrieve existing[id], set only its
lastReportedStatus from the terminated record, and write the merged map back
instead of replacing it with the stale terminated map.
- Around line 578-580: Update extractInstances to resolve the workload type from
instanceType, falling back to the legacy type field when instanceType is
missing, and continue processing only when the resolved type is exactly Pod.
Ensure legacy MiniService records are skipped and remain unaffected, and add a
regression test covering a MiniService with no instanceType.
- Around line 513-520: The eviction failure warning in the deleteICMSRequest
flow must include request, function, cluster, and organization context. Update
the logging around evictInstances to attach those required fields before
emitting the warning, while preserving the existing best-effort continuation and
avoiding OpenTelemetry or RED metrics changes.

TL;DR
kill-all/kill-functiondeleted theICMSRequestCR and reported success, but that alone never terminates the workload: the CR stays stuckTerminatingbehind its finalizer forever, the pod (or MiniService) keeps running, and the function staysACTIVE. This fix makes the commands actually terminate the workload, not just ask NVCA to and hope, and fails closed rather than reporting false success when eviction can't be confirmed.Additional Details
A prior fix (PR #1053, merged) corrected the CLI's reporting — it no longer falsely claims
[deleted]when the object is stillTerminating. QA re-verification of that fix (bug reopened) showed the underlying problem it explicitly flagged as out of scope is real:kill-allcould wait indefinitely and still never succeed, because deleting the CR structurally cannot cause termination.Traced the full mechanism in NVCA's reconciler (
src/compute-plane-services/nvca/pkg/nvca/):syncICMSRequestonly checksAllInstancesTerminatedAndReportedand requeues forever if false. It never evicts anything itself.status.instances: the workload gone from Kubernetes ANDlastReportedStatus == "terminated".lastReportedStatus == "terminated"for a Pod instance isApplyTerminationMessage, reachable only from a genuine upstream ICMS termination queue message — and it writes to that message's own CR, never back onto the original one. Nothing bridges instance status between two different CRs.So
kill-allwas built on an incorrect assumption (delete the CR -> NVCA notices and cleans up). Confirmed live on a local k3d cluster: manually deleting the pod and patching the original CR's ownstatus.instances[id].lastReportedStatustoterminatedis what let NVCA's existing, unmodified reconcile clear the finalizer on its own next pass.The fix:
killMatching(k8s_maintainer.go) now calls a newevictInstancesbefore deleting eachICMSRequestCR. It deletes the CR's Pod-type instances directly (or theMiniServiceobject for a Helm function — its own controller performs real teardown when deleted, so no separate resource-deletion step is needed there), and patcheslastReportedStatustoterminatedon that same CR, satisfying NVCA's own precondition so its reconcile finishes the job for real. If eviction fails for any reason, the item is reported as failed and the CR is left alone rather than proceeding to delete it — this matters most with--force, which would otherwise strip the finalizer and report success while the workload keeps running.For the Reviewer
Core change is
evictInstancesininternal/clusteragent/k8s_maintainer.go, called fromkillMatchingright beforedeleteICMSRequest. Please look closely at:evictInstances— it lays out why deleting the CR alone can never work, and why MiniService deletion doesn't need the same active-teardown workaround Pod deletion does.killMatching's handling of anevictInstancesfailure: it now fails the item and skipsdeleteICMSRequestentirely, rather than logging and continuing best-effort.instanceTypeis checked first, falling back to the legacytypefield (matching the inspector's own tolerant reads), and an unrecognized type is left alone rather than guessed at.lastReportedStatusinto whatever is currently on the server instead of overwriting the whole instance record with the pre-eviction snapshot, so a concurrent NVCA status update isn't clobbered.deleteon Pods,deleteonMiniServiceCRs,updateon theICMSRequeststatus subresource).For QA
k8s_maintainer_test.go:TestKillEvictsPodBackedInstanceAndMarksItTerminated,TestKillEvictsMiniServiceBackedInstanceAndMarksItTerminated,TestKillEvictsLegacyTypeMiniServiceInstance,TestKillStopsOnEvictionFailureInsteadOfReportingSuccess,TestKillPropagatesMalformedInstanceStatusError. Each was verified to fail against the corresponding pre-fix behavior and pass against the fix.go build ./...,go vet ./...,gofmt -l: clean.go test ./...(full module): all pass.ICMSRequestwith the real finalizer (reproducing the exact stuck state and log line from QA's reopening note), rankill-function, confirmed the pod and CR both fully disappear andget-functioncorrectly reports "no scheduled function found" afterward — matching the bug's Expected Behavior exactly.Issues
