 **2. Probes, security contexts and resources go through the null-safe helper, never behind an `if`.** An override written without children is YAML null and erases the block: the container renders `securityContext: null` (unhardened, healthy, silent), a probe disappears, or `resources` loses its requests and computed limits. The `defaultedDict` helper defines the opposite semantics — an empty block means "chart defaults apply" — while an explicitly set value still wins, **including `false` and `0`** (hence the `kindIs "invalid"` check; `default` and `mergeOverwrite` both swallow zero values). Do **not** wrap these blocks in `{{- if }}`: a guard does not render a visible `null`, it removes the probe entirely, which is the same bug with no evidence left.
 
+  The rule is about the **shape, not about those three block kinds**. `satisfactory` shipped 7.0.0 with `game` null-safe and its two neighbours not (Gitea #16): `--set server=null` aborted the render, and a single erased key was the quieter half — a nulled `server.gamePort` rendered `port:` and `nodePort:` empty into the Service and an empty `containerPort` into the StatefulSet, rejected by nothing until the API server saw it. Every chart-owned block a template dereferences belongs behind the helper, and a chart where only *some* of them do is worse than one where none do: whoever sees `game=null` fall back cleanly assumes `server=null` does too.
+
+  **A deliberate exception is fine; an undocumented one is the bug.** `satisfactory.storage` is left un-defaulted on purpose — an erased size yields an invalid PVC that fails at apply time rather than a volume quietly sized by the chart — so `server: null` still renders a PVC without a size. That is a defensible trade and it is *not* the null-safety bug next to it; what makes it safe to leave standing is that the schema, `values.yaml` and the chart page all name it as an exception and point at the issue where it is argued (Gitea #39). Note also where the trade actually bites: only on a **new** install. For an existing release a fallback to the default size would fail too, because a PVC cannot shrink. Do not overturn a reasoned exception inside a bugfix patch — the patch then stops being one.
+
+  **And `helm template` does not render `NOTES.txt`.** A value read there — `server` is read in four files in that chart — stays broken after a fix that looks green in every render, until someone runs a real `helm install`. `helm install --dry-run=client` is not the way around it either: it still wants a reachable API server (measured on helm v3.22.0). What works without a cluster: in a throwaway copy of the chart, wrap the verbatim `NOTES.txt` body in a `{{- define }}` and `include` it into a scratch ConfigMap, which `helm template` *does* render — same engine, same root context, only the sink differs.
+
 **3. Do not hang liveness on an external dependency where a dependency-free path exists.** `zipline` deliberately probes `/` for liveness and `/api/healthcheck` only for readiness and startup, so a database outage cannot restart the pod. Where no such path exists — `outline` returns 500 on `/` when the database is down — all three probes may share the endpoint, but the reason belongs in a comment on the helper, or the next reader will "fix" the inconsistency.
 
   The other half of the same rule: readiness **must** hang on the dependency, and a separate path is not proof that it does. `urlaubsverwaltung` probed `/actuator/health/liveness` and `/actuator/health/readiness` for two years and still stayed 1/1 Ready through a total database outage (#218), because Spring Boot's `readiness` group contains `readinessState` **alone** — the split paths were right, the group content was empty of anything external. Whatever aggregates behind a probe path (Spring health groups, a `/healthz` a framework assembles for you) has to be read off the **running** endpoint, not off the path name; the chart names the members explicitly (`MANAGEMENT_ENDPOINT_HEALTH_GROUP_READINESS_INCLUDE=readinessState,db`) so the composition is in the template rather than in an upstream default.
