The only objects that stay open are the ones passed verbatim into the Kubernetes pod spec (probes, security contexts, global) - the chart does not interpret their contents, so it cannot judge which keys are meaningful. The hardening, probe and resources blocks additionally accept null, because an erased block falls back to the chart defaults (issue #99). Both halves are needed and cover different cases: for a key WITH a chart default Helm's coalescing deletes the null before validation ever sees it, and only the defaultedDict fallback in _helpers.tpl catches that; for a key WITHOUT one (e.g. server.resources.limits) the null survives into validation, where a strict \"object\" would abort the render.

The two halves live in one object under one switch on purpose: whoever opens the port by hand has not added the probe address, and the first narrowed probeSources then drops every probe, so the pod never becomes Ready and the symptom reads as a broken application rather than as a policy. Both numbers are ISTIO CONSTANTS rather than standards, which is why they are values with documented defaults and not template literals - a vendor constant can change, and an operator should be able to correct it without waiting for a chart release.
