Retrofit of #99 for a chart that already carries a values.schema.json, plus the schema type change that goes with it. An override written without children is YAML null. Where the chart defines a default, Helm's coalescing deletes the default before schema validation runs, so the schema never sees the null and cannot reject it: the container rendered "securityContext: null" - unhardened, healthy, silent. Where the chart defines no default (resources.limits), the null survives into validation and a strict "object" type aborted the render. The defaultedDict helper from #96 handles the first case; widening the types of exactly these blocks to ["object", "null"] handles the second. All other keys stay strict, additionalProperties: false is untouched. The probes address the container port by name, so a rebuilt default probe needs no further context. Rendering with normal values is byte-identical to 5.0.0.
