In `@src/clis/nvcf-cli/internal/clusteragent/k8s_maintainer.go`:
- Around line 454-471: The deletion polling loop should enforce the configured
deadline in the resource-check flow: bound each Get call and sleep interval by
the deletion deadline, while preserving true,nil on deletion timeout and
ctx.Err() on caller cancellation. Update the relevant maintainer method and add
a regression test covering a poll interval longer than Timeout.
- Around line 400-402: Update the kill-operation error handling around
aggregateKillError so original failures are retained outside the JSON result,
while preserving the existing failed count and serialized error behavior. Wrap
or join each underlying error when constructing the returned aggregate error so
callers can use errors.Is and errors.As, and add regression coverage for
matching a typed failure cause.
- Around line 381-384: Update the timeout validation in killMatching so negative
opts.Timeout values return an error, while zero continues to select
DefaultKillTimeout. Add a regression test covering a negative --timeout value
and verify the existing default behavior for zero remains unchanged.
In `@src/clis/nvcf-cli/internal/clusteragent/maintainer.go`:
- Around line 117-121: Update the KilledRequest.Error documentation near the
deletion outcome comments to state that it may contain failures from delete,
stripFinalizers, or waitForICMSRequestGone, or otherwise describe it broadly as
a failed deletion operation; keep the comment concise and limited to this
non-obvious contract.

- Around line 818-820: Update the elapsed-time assertion in the test around the
kill-deletion wait to derive its upper bound from the configured Timeout value,
adding a small scheduling tolerance instead of comparing only against
killDeletionPollInterval. Keep the assertion focused on proving the wait
respects the configured timeout.
In `@src/clis/nvcf-cli/internal/clusteragent/k8s_maintainer.go`:
- Around line 482-496: The Get call in the deadline polling logic must classify
only the synthetic local deadline as a timeout. In the flow around
Resource(...).Get and cancel, inspect getCtx.Err() before cancel() and return
true only when the local deadline has actually expired; preserve caller-context
cancellation and other errors. Add a reactor test covering an early
context.DeadlineExceeded returned before getCtx reaches the deadline.

671-710: 📐 Maintainability & Code Quality | 🔵 TrivialCheck whether architecture documentation needs an update.
The new behavior changes the sequence from delete to poll, then classify timeout and finalizer states. If the repository maintains an architecture or sequence diagram for kill operations, update it to show this flow.
As per coding guidelines: "When a change modifies runtime behavior, data flow, or component interactions, ask whether architecture or sequence diagrams need updating."

TL;DR
Fixes
nvcf-cli cluster agent kill-all/kill-functionreporting[deleted]and exiting 0 for ICMSRequests that are still stuckTerminatingbehind a finalizer, so operators no longer get a false success signal while the underlying function pod keeps running.Additional Details (optional for docs, build, test, refactor, ci, chore, style, and revert PRs)
deleteICMSRequestininternal/clusteragent/k8s_maintainer.gocalled KubernetesDelete()on anICMSRequestand treated a nil error (includingNotFound) as "deleted." ButDelete()only guarantees the deletion was accepted — when the object carries thenvca.finalizers.nvidia.iofinalizer (set by the NVCA reconciler), the API server just stampsdeletionTimestampand the object, and the pod it owns, stay alive until NVCA finishes evicting the workload and removes the finalizer itself. If NVCA is slow, stuck, or down, that never happens, but the CLI had already printed[deleted]and exited 0.deleteICMSRequestnow pollsGetafterDeleteuntil the object actually disappears or a bounded--timeout(default 60s, newclusteragent.DefaultKillTimeout) elapses.KilledRequestgained aTerminatingfield andKillResultaTerminatingCount: a request still present at the deadline is reported asterminating, notdeleted, is excluded from the success count, and makes the command return a non-zero-exit aggregate error instead of silently succeeding. The happy path (object disappears quickly) still reportsdeletedas before.While investigating, I traced the NVCA reconciler's deletion-handling code and confirmed that deleting the CR does not itself trigger pod eviction — the reconciler's deletion branch only checks
AllInstancesTerminatedAndReportedand removes the finalizer if true, deferring to the normal ICMS-driven termination-message flow for actual teardown. That's a separate, deeper design question worth the team's attention (whether non---forcekill-allreliably terminates a healthy-but-hung function at all) but out of scope here; this PR's fix is specifically about the CLI no longer lying about the outcome.For the Reviewer
Core change is in
internal/clusteragent/k8s_maintainer.go(deleteICMSRequest, newwaitForICMSRequestGone,killMatching,aggregateKillError) and the type additions ininternal/clusteragent/maintainer.go(KillOptions.Timeout,KilledRequest.Terminating,KillResult.TerminatingCount,DefaultKillTimeout). CLI wiring (--timeoutflag,printKillResultstatus label) is incmd/cluster_agent_maintenance.go.For QA (optional for docs, build, test, refactor, ci, chore, style, and revert PRs)
internal/clusteragent/k8s_maintainer_test.go:TestKillReportsTerminatingWhenFinalizerBlocksDeletion(uses a delete reactor to simulate a finalizer-blocked object survivingDelete, since the fake dynamic client's tracker doesn't emulate real finalizer semantics) andTestKillWithinTimeoutReportsDeletedNotTerminating(confirms the fast/normal path still reports plaindeleted). Both fail against the pre-fix code and pass against the fix.go build ./...andgo test ./internal/clusteragent/... ./cmd/...pass.ICMSRequestwith the real finalizer (no backing pod, so NVCA never removes it, exactly reproducing a stuck-NVCA scenario); pre-fix binary printed[deleted]/exit 0 while the object remainedTerminating; fixed binary correctly printed[terminating: ...], left it undeleted, and exited non-zero after waiting out--timeout.Issues
