There's a small issue found by Qoder:

Issue #1: propagateAnnotationsToTemplate may unnecessarily mutate template annotations

Attribute	Details
Location	pkg/sandbox-manager/infra/sandboxcr/utils.go:80-86
Category	Logic / Safety

Description:

propagateAnnotationsToTemplate calls sbx.GetAnnotations() which can return nil. While Go allows indexing a nil map (returns zero value, no panic), the function always calls template.SetAnnotations(tmplAnnotations) even when no necessary keys were found, replacing the existing nil with an empty map. For CreateCheckpoint, this creates a template with an empty annotations map instead of nil, which is benign but slightly wasteful.

Fix:

Consider returning early if no necessary keys are found in sandbox annotations:

if sbxAnnotations == nil {
    return
}
