Unresolved records are omitted, and conversion helpers receive resolved function and version IDs. Tests and documentation cover this behavior. ChangesFunction identity recovery
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: ⚪ Minimal · up to The change restores function identity for draining records and omits only records whose identity cannot be recovered; no actionable merge-blocking risk remains beyond normal checks and review.

- Around line 254-261: Update resolveFunctionIdentity to accept the source
namespace and skip candidates whose namespace differs before matching instance
IDs. Propagate the namespace from the request through ListFunctions/GetFunction
call sites, and add a regression test covering identical instance IDs in
different namespaces to ensure the request’s namespace determines the returned
function identity.

TL;DR
nvcf-cli cluster agent list-functionsreturnedDRAININGrecords with emptyfunctionId/functionVersionIdafter a function was undeployed, making the record impossible to correlate to the function being drained. Fixed by recovering identity through the shared instance ID between the termination request and the function's creation request, falling back to omitting the record only when no identity can be recovered at all.Additional Details (optional for docs, build, test, refactor, ci, chore, style, and revert PRs)
NVCA relays
TerminateInstances-actionICMSRequestCRs verbatim from the upstream termination message, which never carriesspec.functionDetailsand only optionally carries the deprecatedspec.functionId/spec.functionVersionIdscalars. When those are absent, the CLI'sfunctionIdentity()returned two empty strings, and the caller emitted an anonymousDRAININGrecord with no way to trace it back to a function.internal/clusteragent/k8s_inspector.go:resolveFunctionIdentity, which falls back to correlating a termination request'sspec.terminationMsgInfo.instanceIdsagainst every other listedICMSRequest'sstatus.instanceskeys, borrowing that CR's identity on a match.ListFunctionsandGetFunctionnow useresolveFunctionIdentityinstead of reading identity directly, and skip a record entirely when identity cannot be resolved either way (per the expected behavior in the underlying report: no anonymous entries).scheduledFunctionFromObj/functionDetailFromObjnow take the resolvedfunctionID/versionIDas parameters instead of recomputing them internally.Reproduction was done with a fake dynamic Kubernetes client (the same technique the existing test suite already uses for this code path) rather than a live cluster: hand-planted
ICMSRequestobjects on a live k3d cluster kept getting garbage-collected by NVCA's own reconciler as unrecognized resources, since they had no backing queue message.For the Reviewer
Please look closely at:
resolveFunctionIdentityininternal/clusteragent/k8s_inspector.go— the correlation fallback logic and its scope (sameICMSRequestlist only, no cross-namespace correlation).internal/clusteragent/k8s_inspector_test.go:TestListFunctionsRecoversIdentityForTerminationRequestViaInstanceIDsandTestListFunctionsOmitsTerminationRequestWithNoRecoverableIdentity.For QA (optional for docs, build, test, refactor, ci, chore, style, and revert PRs)
go build ./...,go vet ./...,gofmt -lon touched files: all clean.go test ./...(full module): all pass.resolveFunctionIdentityto direct-only lookup) and pass against the fix, confirming they actually catch the regression.ICMSRequestCR without a real backing workload, and unit tests exercise the exact same code pathlist-functionsuses.Issues
