+    #
+    # And one assertion that spans TWO charts (Gitea #136), the only one here
+    # that does: where a chart dials the Service of another chart of this
+    # repository, its EGRESS rule must contain that chart's POD ports. kube-proxy
+    # does the ClusterIP's destination NAT before the policy is evaluated, so a
+    # rule naming the SERVICE port matches nothing wherever port and targetPort
+    # differ - paperless-ngx shipped exactly that and lost Tika and Gotenberg in
+    # production on 2026-10-15. The pairs are an explicit table in the script,
+    # because no render can discover which Service another chart dials, and the
+    # row is checked with the feature gate on AND off.
+    #
+    # Every one of those failures is SILENT. The API server accepts a policy
+    # whose selector matches nothing - it then sits in the namespace, is listed
+    # by kubectl, reads as a boundary and filters exactly nothing - just as
+    # readily as it accepts one naming a NodePort number, which matches no

Renovate automerges those continuously and never touches the wiki, which is why chart pages carry no version numbers at all and name `Chart.yaml` as the source of truth. Since Gitea #128 **"plain" is mechanically defined instead of being a judgement**: the chart version now states the size of the jump, because `ci/renovate-bump-chart.sh` takes that size from Renovate's update type (app minor → chart minor). An app update that *does* change values or behaviour is not a plain bump and the table applies — but **nothing obliges anyone to go and find out**. That is the deliberate limit of #128, not an oversight: the reading duty was rejected, so the `sonarr` incident in `Lessons-Learned` stays repeatable and a bigger number is the only warning that is given.

+Semver conventions for the chart part. **The chart jump is the greater of the chart's own classification and the jump of what it ships** (Gitea #128) — a maximum, never a replacement, so a value that becomes required stays a major even under an app patch:
 
-- **Patch**: bug fixes without behavior or values-schema change; plain app-version updates.
-- **Minor**: additive, backward-compatible changes (new optional values with unchanged defaults).
-- **Major**: runtime behavior changes or breaking values changes (e.g. probes, security hardening, computed limits, values that become required).

+- **Major**: runtime behavior changes or breaking values changes (e.g. probes, security hardening, computed limits, values that become required); an app **major** update.
+
+The app half of that is mechanical: `ci/renovate-bump-chart.sh` takes the level from **Renovate's update type**, passed in as `{{{updateType}}}`, and not from comparing `appVersion` — `freesailarr` pins every tag in `values.yaml` and its `appVersion` never moves, so a comparison is blind to exactly the case the rule exists for. Non-semver app versions (CalVer, date tags, four-part and suffixed tags — seven charts) stay at **patch** for a minor, because their second position is a month or a flavour and says nothing about the jump; an app **major** still produces a chart major. **It obliges nobody to read the release notes** — that variant was rejected in #128 — so an app minor that changes a default can still reach `main` unremarked; the number stops understating, that is all it does. See the wiki, `Lessons-Learned`.
 
 App-version updates go through PRs (so the validate and install-test pipelines run), not through the `change-app-version.yml` dispatch workflow (which commits directly to main and bypasses both). For app **major** jumps, update stepwise: first to the last release of the old major line (own PR, merge, publish), then to the newest major.

+- **Every chart renders a `NetworkPolicy`, `networkPolicy.enabled` defaults to `true`** (#5); adding one to an existing chart is a **major**. Values: `enabled`, `allowedNamespaces`, `probeSources`, `ingressController`, `egress.extraPorts` — and only the ones that actually reach a rule, because a value that does nothing reads as a control. Each port falls in one of four classes and the class decides the rule: a port a **network** probe addresses stays open (`no from`) until `probeSources` is set, because the kubelet probes from the worker node's IP and no chart can know it; a NodePort-published port stays open (the source is already masqueraded); anything else is restricted to the namespace, `allowedNamespaces` and — for HTTP — `ingressController`; a replica-to-replica bus gets a bare `podSelector`. **`exec` probes are not network probes** (no packet, so the port can be restricted — `valkey`, `minecraft-server`). **`allowedNamespaces` is never shipped pre-filled** — a chart must not bake in an assumption about this cluster's namespace layout, so restrictive is the default and filling it is the deployment adaptation (which is why a sweep produces release-side one-liners: that is the procedure, not a defect list). **A policy applies to traffic that came through a Service** — a Service is only destination NAT and the policy acts at the pod interface; what changes is the *source address*, preserved for pod→ClusterIP→pod (this is why the `ingressController` rule works) and masqueraded to a node for NodePort traffic. **And the whole convention depends on one setting it cannot check: Traefik must not run with `hostNetwork`** — measured, its pods have real pod IPs in `10.42.0.0/16`; on host networking they stop being selectable as pods and every web chart goes dark at once while every pod stays `Ready`. **Pod ports, never NodePorts.** Never `from: []`. Reasoning in Go template comments, never `#` (those ship to the cluster), and such a comment must not spell out its own closing delimiter. Egress is by **port, never destination** — Canal has no FQDN rule and Calico-specific objects are out of scope — so most dependency ports are the *standard* ones and a dependency elsewhere is blocked; `policyTypes` names only what there is something to restrict (`valkey`, `homeassistant`, `satisfactory` are Ingress-only, each argued in its own file). `ci/run-networkpolicy-test.sh` is the gate. Full rules: README, "NetworkPolicies".
 - Resources: requests as values defaults; limits auto-computed by the `_helpers.tpl` helper (`limitFactor` default 3; no CPU limits unless set explicitly).
 - Replicas per workload (explicit `0` allowed) plus a chart-global `scaleDown` flag that overrides them.
 - `icon:` mandatory in every `Chart.yaml`; `helm lint --strict` without findings; CI fixtures under `ci/<chart>/` or a justified exclusion.

StatefulSet with **one** PVC at `/app/data`, carrying all four of Bulwark's directories (admin config, admin state with the audit log, encrypted user settings, telemetry) as subdirectories — one volume because snapshots are atomic per volume and never across them (the `garage` lesson, #81). No ConfigMap, so no `checksum/config` (§9 has nothing to attach to); the `op://` paths are covered by `checksum/secret-ref`. **The defining property, and it governs every value: the VOLUME BEATS THE CHART.** `configManager.get` resolves `admin override > env var > default`, the admin dashboard may write *any* key, and nothing says it just disconnected the chart — so a `helm upgrade` with a changed value can succeed and change nothing. Upstream documents this only for the server URL; it is true of everything. Exactly three values escape it (`SESSION_SECRET(_FILE)`, `ADMIN_PASSWORD`, `BULWARK_TELEMETRY`), and `bulwark.adminConfigReadOnly` closes it at a price that is **threefold and measured**: it freezes the settings policy (and with it the only way to move Web Push off the vendor relay), it freezes an override that *already* exists rather than removing it, and on a **fresh** install it stops `admin.json` from being written at all — so the admin dashboard never comes up and answers HTTP 500 while the pod stays Ready. Hence the default `false`. Sign-in is **OIDC-only** (`oauth.only`), and the way back out of a lockout is **not** `helm upgrade` with it `false` — `oauthOnly` is read through the same precedence chain, so the repair is removing the override in the **admin dashboard**, which is why `ADMIN_PASSWORD` is set at all (it generates no random password and logs nothing — the `#65` analogy does not hold here). Its **redirect URI carries the UI language** (`/<locale>/auth/callback`, 27 locales, and the language is not in the visible URL), so a single registered URI is the likeliest cause of a failed first sign-in. Both `SESSION_SECRET_FILE` and `OAUTH_CLIENT_SECRET_FILE` exist and are used — the better path `garage` and `keycloak` did not have — mounted **without `subPath`** so that a rotation takes effect without a restart, since both are re-read on every use. Two backup statements, both sharp: without the session secret the synchronized settings are unreadable **out of an intact volume**, and if the dashboard's OAuth setup was ever used the client secret sits in `config.json` on that volume in **cleartext**. All three probes are a plain GET on `/api/health` — **not** HEAD, which a `HTTPGetAction` cannot send — and the limit is written at the value: it carries process, HTTP acceptance, a free event loop and Next.js routing, and **nothing** about Stalwart, so with the mail server gone the pod is green. Served only at a host **root** (`NEXT_PUBLIC_BASE_PATH` is compiled in), one replica (single RWO PVC), two emptyDirs for `readOnlyRootFilesystem` (`/tmp`, `/app/.next/cache` — image optimization is active because `images.unoptimized` is in the lite branch only) |

It is also the only chart whose install-test runs in Gateway mode, because that test installs one configuration per chart |
 | `freesailarr` | gluetun VPN media stack (qbittorrent, prowlarr, flaresolverr, radarr, recyclarr, sonarr, seerr, bazarr, and mediathekarr off by default) | Single-pod StatefulSet: all apps share gluetun's network namespace; config volumes via volumeClaimTemplates, media PVCs as existingClaims (optional per-category `subPath`, so one claim can serve all three categories). One ClusterIP Service per app (mediathekarr's carries both of its ports); no global `ingress.domain`. Ingress in two shapes that mix: one host per app (default, each app's host required), or one shared `ingress.host` with the apps as sub-paths (documented ingress exception below) |
 | `garage` | Garage (S3-compatible object store) | **One** node, `replication_factor = 1` — a deliberate trade with its price named (Gitea #81): the volume layer underneath already replicates and encrypts, so Garage replication on top would be nine times the raw data across two layers that know nothing about each other. What that costs is that the factor applies to the **metadata** too, where a corrupted database is upstream-documented as "generally not recoverable" and a replicated volume replicates the corruption. Hence three settings that are mandatory rather than optional: `metadata_fsync = true` (**off** in Garage's defaults), the automatic metadata snapshots, and those snapshots on a **second PVC** — a file-system snapshot of a live metadata database is not a restore point, so the volume backup covers the blocks and not the index. The first PVC carries `metadata_dir` **and** `data_dir` as two subdirectories, because volume snapshots are atomic per volume: that is what keeps index and blocks consistent with each other. Two further properties shape the whole chart: the image is **`FROM scratch`** and contains exactly one file, `/garage` — no shell, so **exec probes are impossible here** and an init container would need a second image — and the RPC secret has to arrive as an **environment variable**, because `rpc_secret_file` rejects any file with a group bit set while the kubelet sets one (the reasoning sits at the value). Started with `garage server --single-node`, which creates the cluster layout in-process before any listener opens and is idempotent on the layout version, and with `--default-access-key`/`--default-bucket`, which **import** key and bucket from the 1Password item — so the vault is the source of truth instead of a copy of what the server generated. Readiness is the admin API's `/health`, liveness and startup deliberately are **not**: `/health` answers 503 until a layout exists, so a node waiting for one would be restarted forever |

 - **The resources paths come from `values.schema.json`, not `values.yaml`** — it is JSON, so `python3` reads it without pyyaml (same runner constraint as `ci/run-trivy-config.sh`), and every chart-owned key must appear there anyway.

A chart whose templates render a resources block while its schema declares none **fails** the test with exactly that message: the schema is then out of sync with the chart.

+### Selector-match render test (all charts, every PR)
+
+`ci/run-selector-match-test.sh [chart …]` (no argument = all charts) renders every chart with the same fixtures the install-test uses and checks that **every label selector the render contains really matches the labels of a pod template in that same render**. Two kinds of object are covered, and both of them fail *silently* when their selector matches nothing:
+
+| Object | What a non-matching selector does | Who notices today |
+|---|---|---|
+| `topologySpreadConstraints` | the constraint is a condition over **zero** pods and is therefore trivially satisfied: nothing is distributed, no event, no log line | nobody — and with `whenUnsatisfiable: DoNotSchedule` the object reads like a guarantee |
+| `PodDisruptionBudget` | the budget does its arithmetic over zero pods and never blocks an eviction, so `kubectl drain` takes every replica at once | nobody — `kubectl get pdb` shows an object that looks like protection |
+
+Neither is a render error, neither fails the install-test, and neither shows up in the diff of the PR that causes it: the chart that breaks it is usually a chart that **renamed a label somewhere else**. Charts answer the first half of that by keeping the selector and the pod labels in one helper (`stalwart.groupLabels`, `keycloak`'s `app` label) — but one definition only helps while nobody writes a second one, and that is the half a test can hold. Introduced with Gitea #96, where the chart-owned spread constraint made the trivially-satisfied case reachable by design rather than by accident.
+
+Three things to know before touching it:
+
+- **Helm is the YAML parser, through the one-template chart `ci/yaml2json`.** The runners have neither `pyyaml` nor `yq` (measured; the same constraint `ci/run-trivy-config.sh` and `ci/run-quantity-render-test.sh` work under), and a YAML reader written in `awk` was the obvious alternative and the wrong one: its failure mode is a parser that quietly reads nothing, finds no selector, reports no mismatch and leaves the test green for a chart it never looked at. So the rendered manifest stream is handed to that chart as a **values file** and comes back as JSON, which `python3` reads from the standard library. The one textual step is the document split on a line that is exactly `---` in column one, and getting *that* wrong does not produce a false pass — the fragment stops being valid YAML and `helm` exits 1.
+- **What is deliberately not checked, named so the gap is not mistaken for coverage.** *Preferred* `podAffinity` and `podAntiAffinity` of either strength are out of scope: their semantics are relative to pods that exist, so a term matching nothing is a legitimate configuration rather than a mistake — a preference that cannot be met is dropped, and an anti-affinity over zero pods is satisfied. And a selector expressed **only** through `matchExpressions` is **reported as "not checked", never counted as passing** — evaluating set-based requirements means reimplementing label-selector semantics, which is a second parser by another name.
+- **`requiredDuringSchedulingIgnoredDuringExecution` `podAffinity` *is* checked** (Gitea #101), and it is the one affinity case that is not a preference: a required term whose selector matches no pod in the release can never be satisfied, so the pod stays `Pending` for good. It is held against **all** pod templates of the render rather than its own, because selecting a *different* workload's pod is the entire purpose of such a term. First and so far only user: `paperless-ngx`' consume CronJob, pinned onto the node of its StatefulSet pod so Longhorn will mount the shared RWX consume volume — where the silent failure would be a mover that stops moving, one `Pending` pod per schedule, with both templates still rendering perfectly.
+- **Two anti-vacuum guards, because this test can be green over nothing.** Both objects are rendered only above a replica threshold, and most charts' CI fixtures sit below it. `ci/selector-match/<chart>.yaml` is a render-only overlay applied **last**, whose only job is to push a chart over that threshold — and a chart that *has* one and still renders no selector **fails**, since that overlay existing is the whole claim that something was checked. On top of that the run fails if **no selector at all** was checked anywhere. Today `stalwart` is exercised through its overlay (two replicas in both node groups plus an `externalServices.valkey.host`, without which the chart's own "cluster with no in-memory store" abort fires), `keycloak` through its ordinary install-test fixture, which already runs two replicas, and `paperless-ngx` through `ci/selector-match/paperless-ngx.yaml`, whose only job is to switch `smbConnection` on so the consume CronJob — and with it the required `podAffinity` — renders at all.
+
+Measured: 30 charts, **6 selectors verified**, no cluster. The fail path was exercised rather than assumed — renaming `node-group` to `nodegroup` in a hand-written copy of the PDB selector produced two `FAIL` lines naming both the selector and the labels actually present, and a non-zero exit; the same was done for the spread constraint's selector. For the `podAffinity` check the same was done by renaming the StatefulSet's `app` label in a throwaway copy of `paperless-ngx` while leaving the CronJob's term alone: one `FAIL` naming the selector, the three pod templates it missed and the labels actually present, and a non-zero exit.
+
+### HTTPRoute render test (all charts, every PR)
+
+`ci/run-httproute-match-test.sh [chart …]` (no argument = all charts) renders every chart with the same fixtures the install-test uses and checks every `HTTPRoute` in the result against the `Service` objects of that **same** render. Introduced with the Gateway-API pilot (Gitea #114); three failure modes, all silent:
+
+| Finding | What it does | Who notices today |
+|---|---|---|
+| `parentRefs` empty | the route attaches to **no** Gateway: created, schema-valid, rejected by nobody, and it routes nothing | nobody — no event, no condition, the only symptom is a hostname that does not answer |
+| `backendRefs` naming a Service or a port that does not exist | the reference is resolved **by name** at runtime and validated by nothing | nobody in CI — `ResolvedRefs: False` lands in a route status that only a Gateway controller writes, and none runs here |
+| a prefix stripped with `ReplacePrefixMatch` while the same route carries no `Exact` match on that prefix with a `RequestRedirect` filter (Gitea #118) | the **slashless** form of the path is rewritten to `/` and answered **200** by the app, under a document URL that keeps the prefix off — so every relative link in that page resolves against the host root, which on a shared host is a *different* application | nobody — the app's own assets and XHRs are served by its neighbour, and the symptom is a half-working UI, not an error |
+
+**The real CRDs in the install-test close none of these gaps**, which is the whole reason this job exists next to them: the Gateway-API schema happily accepts an empty `parentRefs` list, a `backendRefs` entry pointing at a Service that was never created, and a prefix-stripping rewrite with no redirect beside it. The CRDs prove the object is *well-formed*; this test proves it *points somewhere*, and *somewhere right*. The port half is a genuine new exposure rather than a hypothetical: an Ingress backend references its Service port **by name**, while `backendRefs` takes a `PortNumber` and cannot, so the number in the route and the port in the Service are kept in step by hand from now on.
+
+The third check is a **pairing within one HTTPRoute object**, and the scope is deliberate: Gateway-API matching precedence is a property of a single route, so a redirect in a *different* route (a different hostname) says nothing about this one. Precedence also makes the pairing a question of existence rather than order — an `Exact` path match outranks every prefix match, so the redirect rule wins wherever it is emitted, and the rules' length-descending order stays a rendering convention. `freesailarr` is the first chart it applies to — **and, after group 3, still the only one.** The line that used to stand here said `bulwark` was the second `rewrite-target` chart and would meet the same check when group 3 landed. Group 3 landed and it does not: **`bulwark` has one Ingress object, no `rewrite-target`, and cannot have one** — `NEXT_PUBLIC_BASE_PATH` is compiled into its bundle, so it cannot be served under a sub-path at all and its route is one rule at `/` with no `URLRewrite` filter. Every occurrence of the string `rewrite-target` in that chart is an explanation of *why it does not help*, and #114's measured table arrived at "`bulwark`, `freesailarr`" by grepping for the string rather than for the annotation. The check still runs over all charts for the reason below — the mistake arrives by copy into a chart whose own diff nobody reads for it — not because a second chart is known to need it.
+
+Three things to know before touching it:
+
+- **Helm is the YAML parser**, through `ci/yaml2json`, for the same reason as the selector-match test above — the runners have neither `pyyaml` nor `yq`, and a parser written in `awk` fails by reading nothing and reporting nothing.
+- **What is deliberately not checked**, named so the gaps are not mistaken for coverage. *That traffic flows* — no Gateway controller runs in CI and none will, so `Accepted: True` is not obtainable; that claim is simply not made anywhere in this pipeline. *That any redirect is ever served* — the pairing check proves the rendered **object** carries a `RequestRedirect` rule on the bare prefix and nothing more: whether an implementation honours the `statusCode` or declines it and fails the whole route is outside what a render can see. *Mutual exclusion with the Ingress* — each chart aborts its own render when `ingress.enabled` and `httpRoute.enabled` are both true, which is where it belongs: this test renders one configuration per chart, and a rule here would have to assume the switch is chart-global, which may not survive the multi-app charts of the sweep. *Cross-namespace and non-Service backends*, and a rule with no `backendRefs` at all (legal for a filter-only rule) — all three are **reported as "not checked", never counted as passing**. The redirect rule the pairing check demands is itself backend-less, so a chart that satisfies that check also earns one "not checked" line; both verdicts are correct at once.
+- **Two anti-vacuum guards**, because the convention ships `httpRoute.enabled: false` and this test would otherwise be green over nothing. `ci/httproute/<chart>.yaml` is a render-only overlay applied **last** whose one job is to put a chart into Gateway mode — and a chart that *has* one and still renders no route **fails**. On top of that the run fails if **no assertion at all** held anywhere. `cyberchef` is exercised through its ordinary install-test fixture (which installs in Gateway mode, see below), every other converted chart through its overlay. For a multi-app chart the overlay also has to enter every shape the template has: `ci/httproute/freesailarr.yaml` moves one app onto a host of its own so that the shared-host route *and* the per-app route are both rendered.
+
+Measured in CI (run 719, the pilot): **30 charts, 4 assertions held**, whole job 13 s including checkout and the Helm setup, no cluster. Group 1 took that to 20 assertions over 10 charts and group 2 to 36 over 15; the prefix/redirect pairing of Gitea #118 adds the first check since the pilot rather than a chart, which brought it to 37 over 15 — one assertion for `freesailarr`'s `/qbittorrent`, plus one more "not checked" line for the backend-less redirect rule it demands. Group 3 took it to `56` assertions over `21` charts, from six charts of which three contribute more than one route: `keycloak` 4 (public and admin routes), `matrix-synapse` 4 (homeserver and delegation routes), `homeassistant` 5 (two routes, three rules — its overlay was the first in the repo that has to *supply* hostnames, since the chart has no `ingress.domain`), `bulwark` 2, `stalwart` 2, `ytdlp-web-player` 2. **`rss-bridge` finishes the sweep at `58` assertions over `22` charts** — read on this branch, which does **not** contain the realm-hostname round of Gitea #122 (measured separately at `60` over `21`, on a branch that did not contain `rss-bridge`). **Neither total includes the other, so the figure to trust from either is the delta**; the running total was therefore read off the first branch that contained both — the realm-hostname branch rebased onto this one — and it is **`62` assertions over `22` charts**, `0` failed. `keycloak` contributes `8` of them: one `parentRefs` and one `backendRefs` assertion for each of its four routes, the two realm routes adding one "not checked" line each for their backend-less redirect rule (`keycloak: ok (8 assertion(s) held, 2 not checked)`). The #118 prefix/redirect pairing deliberately does **not** fire on those two: it is scoped to rules that strip a prefix with a `ReplacePrefixMatch` rewrite, and a realm route strips nothing — it redirects the bare root of a hostname that serves one realm. The delta here is one route, so two assertions, and its overlay is the **second** that has to supply hostnames — for a different reason than `homeassistant`'s, which is worth keeping apart. `homeassistant` has no `httpRoute.hostnames` key at all and its overlay supplies the names through `ingress.hosts`; `rss-bridge` *has* the key and its overlay fills it, because this chart has no `ingress.domain` to fall back to either but its hostnames are unambiguous (one Service, one path). **The MTA-STS routes of Gitea #123 add `2`**, and they are the entry that shows what this figure means once the sweep is over: `stalwart` goes from `2` assertions to `4` — one `parentRefs` and one `backendRefs` assertion for its new MTA-STS route — and **the chart count does not move at all**. Every earlier entry in this history grew because a chart *joined* the list; this is the first that grew because a chart already in it gained an **object**, which is the ordinary shape of the next one too. Following the same delta rule, and read off the first run that contains all three rounds — this branch, rebased onto a `main` that already held `rss-bridge` and the realm hostnames — the figure is **`64` assertions over `22` charts**, `0` failed. The delta counts only because the overlay was extended to enter the new shape: `ci/httproute/stalwart.yaml` carries an entry with a `clusterIssuer`, one without, and one host on a **subdomain**. An overlay left alone would have added a second route this test never rendered — the anti-vacuum rule biting on a *second* object inside a chart that already passes, which no per-chart "has an overlay" check can see. **The Ingress half of that feature is not covered here at all**, because an overlay's one job is to switch Gateway mode on; it sits in `ci/stalwart/test-values.yaml`, where the install-test has a real API server accept it.
+
+**And in the same PR that chart's install-test went green, which is the event Gitea #51 was waiting for.** It had failed on the Gitea runner for months (uid 33 unable to read `/app/index.php`, startup probe 403 through its whole budget), and the chart was deliberately kept *out* of `ci/excluded-charts.txt` precisely so that the day it passed would be noticed rather than silenced. It passed: k3d cluster up, `helm install` in Ingress mode, pod `1/1 Ready` in 22 s with 0 restarts, and no `Permission denied` anywhere in the job. **The chart cannot be the reason, and that is measured rather than argued** — the rendered output for the fixture values is byte-identical to `origin/main`, so the pod spec that installed is exactly the one `main` produces. The implicated layer is the runner, which is where #51 had already put the burden of proof. Two cautions belong with the result: **nobody has identified what changed on the runner**, and a green test does not explain itself — it has reproduced on every run of that branch since, across several commits, so it is not a fluke - but that is still a colour and not a cause; and the install covers **Ingress** mode, since that is what the fixture installs — so this chart's Gateway mode stays render-only, exactly like its 21 siblings rather than worse than them.
+
+The fail path was exercised rather than assumed: a Service renamed in the route, a port the Service does not expose, a port left out entirely, an emptied `parentRefs` with the chart's own guard disabled, an overlay that renders no route, a run with zero assertions, and — for the pairing — both the redirect rule deleted outright and the redirect pointed at a path other than the one stripped; each produced a `FAIL` naming both sides and a non-zero exit.
+
+### Bump-level test (the version-bump hook, every PR)
+
+`ci/run-bump-level-test.sh` (no arguments) holds every case of `ci/renovate-bump-chart.sh` against the version string it writes. Added with Gitea #128, which is what made it necessary: until then the hook was a calculator with one branch, and with the update type coming from Renovate it became the thing that *says how big a change a cluster is being offered* — while the chart version is the only signal anything downstream sees (see "Chart dependencies": Fleet reads our chart version and nothing inside the package).
+
+Its failure mode is the silent kind this section's two rules are about: **a wrong level is a valid version string.** The PR goes green, the chart publishes, and the only symptom is a number that understates what it ships. Nothing in the pipeline reads that number, so nothing but a test can.
+
+A case is not a function call, because the script reads the **base commit** (`git show HEAD:<chart>/Chart.yaml`) *and* the working tree: each of the 49 cases gets a throwaway `git init` under `mktemp -d`, one commit carrying the base `Chart.yaml`, and the new one written over it uncommitted — the state Renovate's `postUpgradeTasks` hook actually runs in. Signing is switched off per command, since this workspace signs through an SSH signer and a throwaway repo has no business invoking it. No Helm, no cluster, no `pyyaml`, no `yq`, no Docker: the fixtures are six-line `Chart.yaml` files written with `printf`, and the assertion is one `version:` line read back with `sed`. The job therefore carries no Helm step and takes about a second.
+
+What the cases cover: each update type, the `freesailarr` shape (an app minor while `appVersion` stands still), all seven non-semver app versions plus the majors that must *not* fall back, the maximum rule in both directions including a stale branch version that must **not** be kept, a missing and an empty and an unknown second argument, and the inputs the script must leave alone — a chart new on the branch, `template-chart`, a `.github/` or `ci/` argument, no argument at all. The full `version:` line is asserted in every case, so the `+up` suffix and its dash-to-dot normalization are covered throughout.
+
+**What it cannot assert, and does not pretend to:** that Renovate passes the update type at all. The hook runs only when the command is allow-listed on the shared instance, which is outside this repository — which is why a *missing* second argument is itself a case here, and why the change that introduced it carries a dry run instead of a claim (see "The version-bump hook").
+
+### YAML-scalar render test (all charts, every PR)
+
+`ci/run-yaml-scalar-render-test.sh [chart …]` (no argument = all charts) renders every chart with the same fixtures the install-test uses and checks that **every scalar Kubernetes types as a string really arrived as one**. Introduced with Gitea #11, where a value rendered without `| quote` had been shipping in a chart for months; #112 turned out to be the same defect in the same chart's `env` block. Three assertions, and all three are properties the API itself requires — there is no chart for which the opposite is a legitimate configuration, which is why this test needs no per-chart expectations:
+
+| Assertion | What a bare render does | Who notices today |
+|---|---|---|
+| `CronJob.spec.schedule` is a non-empty string | a schedule beginning with `*` (the commonest cron notation there is) or with `@` **aborts the render** — YAML reads the leading character as an alias or a reserved indicator | the operator, eventually: the error names the **template** and their own value appears nowhere in it, and **quoting it in the values file does not help**, because Helm passes the string's content through |
+| every `env[].value` of every container and initContainer is a string | `"true"` and `"0755"` are legal plain scalars that are **not strings**: the chart renders perfectly and the API server rejects the object with `cannot unmarshal bool into Go struct field EnvVar.value of type string` | nobody until apply time — which in this repo means the install-test or a cluster, never the render |
+| every `metadata.labels` and `metadata.annotations` value is a string | both are typed `map[string]string`, so a unit-less `100` in an upload-size annotation is rejected whole | nobody in the render |
+
+**Why this job exists next to the render tests that already run:** the object that carried the original defect is rendered by **no fixture at all**. `paperless-ngx`' consume CronJob sits behind `smbConnection.enabled`, which is `false` in the chart defaults and `false` in its install-test fixture — deliberately, since the CI cluster has no SMB CSI driver. So nothing in this repository ever produced that object: not lint, not the other render tests, not the install-test. A test that renders only what the fixtures already render would have been just as blind, which is the whole argument for the overlays below.
+
+Three things to know before touching it:
+
+- **Helm is the YAML parser**, through `ci/yaml2json`, for the same reason as the two tests above — the runners have neither `pyyaml` nor `yq`, and a parser written in `awk` fails by reading nothing and reporting nothing.
+- **Two anti-vacuum guards.** `ci/yaml-scalar/<chart>.yaml` is a render-only overlay applied **last**, whose job is to switch such objects on *and to feed them the hostile values* — a schedule beginning with a star, an `env` value that is a bare `true`. A chart that *has* one and still renders none of the three kinds **fails**, and the run fails if **nothing at all** was asserted anywhere.
+- **What is deliberately not checked**, named so the gaps are not mistaken for coverage. A value rendered into a scalar that is **hand-quoted in the template** (`"{{ .Values.x }}"`) is a string in the output by construction, so this test is blind to it — what it can still do is break the YAML when the value itself contains a quote or a backslash, and only `| quote` fixes that. Everything that is **not** a label, an annotation, an `env` value or a schedule: a bare `storage:` or `className:` is just as unquoted, but its value space is DNS labels and quantities, where no legal value is YAML-ambiguous. And **whether a cron schedule is a *valid* schedule** — that is the controller's judgement, and narrowing the schema to a regex was considered and rejected, because the defect was never a wrong schedule but a correct one rendered bare.
+
+Measured locally: **30 charts, 408 scalars verified, 0 failed**, no cluster. The fail path was exercised rather than assumed, in all three of its shapes, against a throwaway copy of the chart as it stands on `main`: the unquoted schedule aborted the render with `yaml: line 6: did not find expected alphabetic or numeric character` and the test reported it; with only the schedule quoted, the star-valued `env` entry aborted the render on the StatefulSet instead; and with only the bool-looking value left — a render that **succeeds** — the type assertion produced a `FAIL` naming the variable, the container and the exact API-server message. **Seven charts still render their `env` block bare** (`matrix-synapse`, `minecraft-router`, `minecraft-server`, `rallly`, `satisfactory`, `teamspeak-server`, and `paperless-ngx` until #11); the test is green for them only because their fixtures set no hostile `env` value, and the overlay is what makes the difference between covered and merely green.
+
+### NetworkPolicy render test (all charts, every PR)
+
+`ci/run-networkpolicy-test.sh [chart …]` (no argument = all charts) renders every chart with the same fixtures the install-test uses and holds **every `NetworkPolicy` it renders against the pod specs, probes and Services of the same render**. Introduced with Gitea #5, which put a policy into all 29 installable charts at once with `networkPolicy.enabled: true` as the default — 29 objects whose every failure mode is silent, because the API server accepts a policy that filters **nothing** exactly as readily as one that filters **everything**.
+
+| Assertion | What goes wrong without it | Who notices today |
+|---|---|---|
+| the `podSelector` matches a pod spec of the same render | the object sits in the namespace, is listed by `kubectl`, reads as a boundary and filters nothing at all — usually because a label was renamed in the workload template, a different file and a different diff | nobody, ever: nothing is denied, so there is no symptom to trace |
+| every **ingress** port is a `containerPort` of the selected pods | a NodePort number where a pod port belongs. The policy is evaluated at the pod's interface, *after* kube-proxy translated the port, so `30025` matches nothing while looking strict — and being the only rule for that port, it blocks every inbound connection instead | nobody in CI (see below), and in production as a service that went mute |
+| no ingress rule allows every source by accident | `from: []` allows everything, identically to having no `from` at all, while reading in a diff and in `kubectl` output as a restriction — the one mistake in this class that makes a policy *weaker* while looking *stricter* | nobody |
+| every port a **network** probe addresses is either unrestricted, or the chart offers `networkPolicy.probeSources` **and** says in `NOTES.txt` what a wrong CIDR costs | the kubelet probes from the IP of the worker node running the pod, which no chart can know. A restricted probe port without that address drops every probe: the pod never becomes `Ready`, the rollout times out, and the symptom reads as a broken application | the install-test, in production's CNI — **but not in CI**, see below |
+| **cross-chart egress**: where a chart dials another chart *of this repository*, its egress rule must contain the **pod** ports behind that chart's Services (#136) | an egress rule naming the **Service** port. kube-proxy does the ClusterIP's destination NAT *before* the policy is evaluated at the pod's interface, so the policy sees `podIP:targetPort` and the rule matches nothing wherever `port` and `targetPort` differ | nobody: the symptom is a **timeout**, not `connection refused`, and no error mentions a NetworkPolicy — `paperless-ngx` 14.0.0 shipped it and cost an outage on 2026-10-15 |
+
+Egress ports are otherwise **deliberately not** held against the pod's `containerPort`s: an egress port is a port on the *destination*, and that comparison would fail every chart that reaches a database.
+
+**The one exception is the fifth row, and it is the only assertion here that needs two charts.** For a database, a cache or the web the destination is in no render this repository has — but it *is* in a render when one chart dials the Service of another, and `paperless-ngx` → `apache-tika`, `gotenberg` is the single place in the repository where that happens (checked for #136: the three other charts naming `port: 80` in a policy are aiming at the **internet**, where there is no DNAT and 80 is the real port). So the pairs live in an explicit table (`EGRESS_PEER_ROWS`) rather than being discovered — a chart cannot know which Service another chart dials, because the address is a value or a 1Password field — and a row naming a chart that no longer exists **fails** instead of being skipped. Each row is checked on **two** renders: with the feature gate **on** the containment must hold, and with it **off** the requirement must not apply *and* those ports must be gone, so a gated rule cannot quietly become one that permits what the release cannot use.
+
+Two guards beyond the four, both earned rather than designed. **A chart that renders no policy at all fails** — that is how this issue decayed in the first place: `garage` (#81) and `keycloak` (#83) were both created *after* #5 was filed and both arrived without a policy, `keycloak` with its unauthenticated management surface on 9000. And **a `#` comment inside a rendered policy fails**, because a `#` comment is part of the *object*: it travels into the cluster, shows up in `helm get manifest` and `kubectl get -o yaml`, and lands in every release diff. Reasoning belongs in Go template comments, which render nothing. Both precedent charts failed that check when it was first run, which is what it is for.
+
+Four things to know before touching it:
+
+- **Assertion 3 is stricter than it first reads, deliberately.** A *missing* `from` is the documented open form and both precedent charts use it on purpose, so banning it outright was not an option. It is accepted only where the render itself justifies being open: every port of the rule is addressed by a network probe, or is published by a `NodePort` Service in the same render. Anything else is an allow-all nobody chose.
+- **`exec` probes are not network probes**, and that distinction carries real weight rather than being a technicality. An `exec` probe runs inside the container through the kubelet's runtime and puts no packet on the network, so a chart whose probes are all `exec` can restrict its port by source with **no `probeSources` at all** — which is why `valkey` and `minecraft-server` have the tightest policies in the repository and every web app has a looser one.
+- **Subchart documents are skipped by the comment assertion**, for a structural reason and not a lenient one: a dependency is fetched from the Helm registry rather than from the copy in this repo, so the policy `paperless-ngx` and `stalwart` bundle is whatever `valkey` version is *published*, and nothing in the parent chart can change its rendered comments. The subchart's own PR is where it is caught, because this test runs over `valkey` too.
+- **Anti-vacuum guard**, as in the tests above: `ci/networkpolicy/<chart>.yaml` is a render-only overlay applied **last**, whose job is to render the **source-restricted probe rule** — a branch no chart's own defaults ever reach, and the one containing the expensive mistake (a `namespaceSelector` and a `podSelector` written as two list entries instead of one would be an OR, opening the port to every pod in `kube-system`). A chart that *has* an overlay and still renders no restricted **probe** rule fails. That counter is specifically the probe rule and not "any restricted rule", because `keycloak` restricts two rules in its own defaults and would have satisfied a looser guard while the branch went unrendered.
+
+Measured locally: **30 charts, 210 assertions held, 0 failed**, no cluster, ~15 seconds. All twelve fail paths were exercised rather than assumed — and one earned its keep immediately: the `probeSources` check was a substring test, so a chart whose key had been **deleted** while the long comment above it still discussed the value passed it. It now looks for the key. The cross-chart assertion added two of those 210, and its own six fail paths were executed the same way: a required port removed from the rule, a wrong number in its place, a peer chart renamed away, the policy's name no longer following the `<release>-<chart>-<kind>` convention, the peers rendering no Service at all (which would make the requirement empty, and is treated as a failure because an empty requirement reads exactly like a satisfied one), and the gated rule made unconditional — which is the failure path of the *gate-off* half, since with the gate off and the rule properly gated the assertion must stay silent.
+
+**What this test does not and cannot cover, named so the gap is not mistaken for coverage:** that traffic still flows. No ingress controller runs in the install-test cluster, so the path from Traefik to a pod is proven nowhere in this pipeline — and, measured on the PR for #5, **k3s exempts the kubelet's probe traffic from policy**, so a blocked probe path does *not* turn the install-test red either (`cyberchef` became `Ready` in 69s with its probe port restricted to an address no probe can come from). What the install-test *does* prove is enforcement of everything the application itself needs: with `outline`'s DNS egress rule removed, its pod never became `Ready` and the job failed after 5m59s. So the net under this convention is real, but it is an **egress** net — which raises the stakes for assertion 2, since a wrong ingress port is caught mechanically here or not at all.
+
 ### Install-test (PR pipeline stage 2)
 
 For every chart a PR changes, `ci/run-install-test.sh <chart>` runs against a throwaway k3d cluster: it applies the stub `OnePasswordItem` CRD plus the chart's fixtures, `helm install`s the chart with its CI values, and waits for all Deployments/StatefulSets to roll out (per-chart timeout). Since probes and security hardening are active on all workloads, "Ready" means the app actually answers. On failure the job dumps pod descriptions, events and container logs.

 One rule those overrides share, learned from `searxng` and worth knowing before writing the next one: **a capture group is a claim about how the value is compared.** Renovate's regex versioning parses `major`, `minor`, `patch`, `build` and `revision` with `Number.parseInt` (`modules/versioning/regex/index.js`, `_parse`), so a non-numeric commit hash captured as `build` becomes whatever digits lead it — `9fea41204` is `9`, `777ba8fa4` is `777`, and a hash starting with a letter is `NaN`. Measured on renovate 41.173.1 and 44.48.0, that makes Renovate offer an image pushed *earlier the same day* as an update to a newer one — a downgrade wearing the clothes of a routine date bump, which is exactly what a review waves through and automerge then carries to `main`. Parts of a tag that carry no ordering belong **outside** every group: the anchored pattern still requires them to be there, they simply take no part in the comparison. `prerelease` is not the way out either — it sorts correctly but marks every tag `isStable === false`, which hands the whole chart to `ignoreUnstable`. `freesailarr` has no **app-version** block on purpose — see the images exception above; a block would either duplicate the `helm-values` updates or rewrite an `appVersion` that selects no image. It does carry one `customManagers` block, for `mediathekarr`: that image is pinned by digest because its tags carry no version (`latest` is a 2024 build, `beta` moves), and the built-in `helm-values` manager reads only `repository`/`tag` and skips it (`skipReason: invalid-value`), so the two cannot collide. Digest rules need the same guard as versioning rules and for a sharper reason: while the pin is current, a matching rule and a broken one produce the identical empty result. Verified with two dry-run fixtures — the real digest yields no update, a deliberately stale one yields exactly one `digest` update back to the pinned digest.
 
-A consequence of pinning every tag in `values.yaml`: `ci/renovate-bump-chart.sh` sees an unchanged `appVersion` and bumps the chart **patch**. That holds for all ten images alike, the digest-pinned one included — none of them is special — and it is the intended outcome, since `appVersion` here is the chart's own marker rather than a tracked upstream version.
+A consequence of pinning every tag in `values.yaml`, and the measurement that forced the change in Gitea #128: `ci/renovate-bump-chart.sh` used to see an unchanged `appVersion` and bump the chart **patch** — for all ten images alike, the digest-pinned one included. `appVersion` here is the chart's own marker rather than a tracked upstream version, so a comparison had nothing to read: prowlarr's `2.5.2 → 2.6.5` was an upstream **minor** that arrived as a chart patch. Since #128 the level comes from Renovate's classification instead (`{{{updateType}}}`, the hook's second argument), so a minor among the ten makes a chart minor and a mixed group takes the highest level in it. The `+up` suffix still follows `appVersion` and therefore still stands still.
+
+**That open point is now decided (Gitea #128), and the decision is deliberately smaller than the problem.** The gap was real: the automatic patch was also a *classification*, and the convention exempts a "plain app-version bump" from the wiki obligation — so an image update that quietly changed a **default** was the one case where nothing reviewed it and nothing documented it. It had already happened: the `sonarr` 4.0.19 bump carried upstream's removal of the hard-coded trusted proxy networks and reached `main` unremarked (see [Lessons learned](https://git.jk-dev.de/jlab-cluster/helm-charts/wiki/Lessons-Learned)). What was decided is **the classification and not a reading duty**: the chart jump follows the app jump, so the number stops understating what it ships. The variant that would have caught that incident at its origin — *a chart minor or major obliges reading the upstream release notes, with the result stated in the PR even when it is "nothing found"* — was **rejected**, and its price is the part that stays: nobody is obliged to look behind the number, so an app minor that changes a default can still reach `main` unremarked. What the bigger number does buy is visibility where a patch has none — Fleet's `fleet.yaml` in `cluster-config` sees only our chart version (see "Chart dependencies"), so a minor is a number other gates can act on. Whether `cluster-config` actually distinguishes update types is **not** visible from this repository; that is the mechanism which makes the number effective, not a claim that it is in use.
 
 Two dependencies are constrained beyond their versioning. **nginx** (the Synapse delegation sidecar) is limited to **even minors** via `allowedVersions`. nginx numbers its release branches by minor — even is stable, odd is mainline — and the chart belongs on stable. Patch updates inside the stable branch still flow through normally. The constraint tolerates a variant suffix (`1.30.4-alpine`) on purpose: docker versioning only ever offers candidates carrying the current tag's suffix, so a suffix-blind constraint would silently freeze nginx the day the sidecar moves to a slimmer base image — a switch to `1.30.4-alpine` that #84 has commissioned a check on — with no error and no warning.
 
 **linuxserver/qbittorrent** (freesailarr) excludes two tags by name, `14.3.9` and `20.04.1`. They are leftovers from earlier linuxserver tagging schemes, and docker versioning sorts both above every real release, so Renovate offers them as major updates — PRs #152 and #153 were exactly that. They are named rather than cut off with an upper bound like `<10`, because a bound would eventually reject a genuine major, while two finished artifacts cannot grow and therefore cannot hide a future release. The same guard as for nginx applies and was run: a lookup from `currentValue 4.6.4` still offers `5.2.3` as a **major**, so the filter does not silently empty the update list. That fixture also shows the cost of leaving it alone — without the rule the very same lookup offers `20.04.1` and never mentions the real `5.2.3`, since Renovate fills the major bucket only once.
 
+### The one grouped chart
+
+`freesailarr` is the only chart whose updates are **grouped**: all ten of its images arrive as one PR per cycle (`groupName: "freesailarr stack"`), where every other chart in this repo gets one PR per image. For the others that is already the same thing — one chart, one image — so this is a rule about a ten-image chart rather than a change of policy. It is also the only `groupName` in `renovate.json5`, and it reverses what the comment above the app-version managers describes: the `helm-values` manager finding those ten images and proposing "one update per image". That sentence described what Renovate does, not what the chart wants.
+
+**What it fixes, measured on 2026-10-12.** Eight of the ten images had an open Renovate PR simultaneously (#102 bazarr, #103 qbittorrent, #104 sonarr, #105 flaresolverr, #106 recyclarr, #107 prowlarr, #108 radarr, #111 seerr). Each edits `freesailarr/values.yaml` and — through the `postUpgradeTasks` hook — `freesailarr/Chart.yaml`, so the API reported `mergeable: false` for all eight: they rewrite the same `version:` line. One could merge; the other seven then needed a rebase each, and every rebase restarts the most expensive install-test here (a real Wireguard tunnel, ten containers). A sharper second symptom came with it: all eight carried `version: 3.1.1+up1.0.0 → 3.1.2+up1.0.0` while `main` already stood at `3.3.0+up1.0.0`, because the hook derives everything from the **base commit** and those branches predated the Gateway-API rounds. A rebase repairs that, which is precisely the problem — nothing *fails* if the rebase does not happen first, so the repair depends on the bot reaching the branch before a human reaches the merge button. Grouped, there is one branch, one `version:` computed from one base, one publish and one install-test run.

+- **Matched by file name, not by a list of images.** What causes the collision is "touches `freesailarr/Chart.yaml`", true of every dependency Renovate finds in that `values.yaml` regardless of manager or datasource. A `matchPackageNames` list would be a second place to keep the chart's image set current, and its failure mode is silence — an image added later never joins the group, with no error (#158: a valid rule is not a matching rule).
+- **`mediathekarr` is in the group** although it comes from its own `customManagers` block: its digest PR edits the same two files and blocks the others identically. `digest` is in `matchUpdateTypes` for exactly that, and its own block is untouched — a group decides which *branch* an update lands on, not how it is found.
+- **`gluetun` and the `busybox` init image are in too.** Neither "gluetun is the tunnel" nor "busybox is only an init container" has anything to do with the blocking, and a grouped PR hides nothing: the review still sees every changed line, just not eight times over.
+- **Majors stay out**, via `matchUpdateTypes: ["patch", "minor", "digest"]`. An app major must be taken stepwise in its own PR, and `separateMultipleMajor` splits a multi-major jump to produce that sequence; a group throwing a major in with seven patches would undo both.
+
+**It takes two `packageRules`, and that is not cosmetic.** Renovate refuses `matchUpdateTypes` and `separateMinorPatch` in one rule — `packageRules cannot combine both matchUpdateTypes and separateMinorPatch`, a config-validation error — which is consistent, since `separateMinorPatch` is what *decides* the split a rule would then be selecting on. So one rule groups the non-major update types and a second sets `separateMinorPatch: false` for the same file. Without that second rule the group still arrives as **two** PRs: verified by dry-run (`--platform=local --dry-run=full`, real registries) against a checkout holding those eight updates, they landed on `renovate/freesailarr-stack` (the three minors) and `renovate/patch-freesailarr-stack` (the five patches) — note that `separateMinorPatch` **prefixes** the branch rather than suffixing it, which makes the second name easy to miss in a branch list. With both rules, one branch carries all eight. The global `separateMinorPatch: true` keeps its reason for every other chart; "one red install-test must not block unrelated updates" simply does not apply within a single chart, where the updates share a pod, a chart version and a publish.
+
+What this cannot show from inside the repo: Renovate runs as the shared instance outside it, so a valid config and a correct local lookup are the evidence available — not the behaviour of the next real run.
+
 Not managed: `ci/**` (install-test fixtures pin throwaway infrastructure to major lines on purpose) and `template-chart/**` (placeholder image). A consequence worth knowing: `ci/matrix-synapse/fixtures.yaml` pins a Synapse image that Renovate will not follow — bump it by hand when the chart moves a major.
 
 ### The version-bump hook
 
-Renovate only rewrites `appVersion:` or an image tag; it knows nothing about `version: <chart-semver>+up<app-version>`. Left alone, every chart PR would fail the `build-chart` version check. `ci/renovate-bump-chart.sh <chart-dir>` closes that gap and is wired up as a `postUpgradeTasks` command:
+Renovate only rewrites `appVersion:` or an image tag; it knows nothing about `version: <chart-semver>+up<app-version>`. Left alone, every chart PR would fail the `build-chart` version check. `ci/renovate-bump-chart.sh <chart-dir> [update-type]` closes that gap and is wired up as a `postUpgradeTasks` command. **Since Gitea #128 the chart jump follows the app jump**, which turned the script from a calculator into deciding logic:
 
-- **app major changed** → chart major (`6.0.0` → `7.0.0`), matching "runtime behavior changes" in the semver conventions
-- **anything else** (plain app update, sidecar image) → chart patch
+- **update type `major`** → chart major (`6.0.0` → `7.0.0`), matching "runtime behavior changes" in the semver conventions
+- **update type `minor`** → chart **minor** (`6.0.0` → `6.1.0`) — the part that was missing, and where the incident sat
+- **`patch`, `digest`, `pin`, `pinDigest`** → chart patch
+- **no or unknown update type** → the pre-#128 behaviour: app major changed → chart major, anything else → chart patch
+- **never below what the branch already carries** — the maximum rule below
 - the `+up` suffix is recomputed from the new `appVersion`, dashes normalized to dots
 
-Everything is derived from the base commit, so the script is idempotent across the multiple updates a single Renovate branch can carry.
+**The level comes from Renovate, not from `appVersion`,** and that is the whole point: `freesailarr` keeps a hand-maintained `appVersion` for ten upstreams, so the update that prompted the rule moved an image tag in `values.yaml` while `appVersion` stood still (see "The one grouped chart" above). Verified rather than assumed — Renovate 44.155.7, keycloak pinned one minor back: `--platform=local --dry-run=full` classifies the update (`"updateType": "minor"`) but **never reaches the branch worker**, so it cannot show the hook at all; driving Renovate's own post-upgrade executor against a throwaway checkout does, and logs `cmd: "ci/renovate-bump-chart.sh keycloak minor"` with the script answering `1.3.0+up26.7.0 -> 1.4.0+up26.8.1 (update type minor)`.
+
+**Non-semver app versions stay at patch for a minor**, with the reason in the convention rather than in a footnote: in CalVer and date tags the second position is a *month*, so following it would mint a chart minor every month that says nothing about the risk, and in a four-part or suffixed version the positions are not semver positions at all. Seven charts on `main` are in that class — `rss-bridge` (`2026-09-30`), `homeassistant` (`2026.8.3`), `searxng` (`2026.9.13-3b8009065`), `minecraft-server` (`2026.8.2-java25`), `apache-tika` (`3.3.1.0-full`), `teamspeak-server` (`6.0.0-beta13.1`), `valkey` (`9.1.2-alpine`) — and an app **major** is not subject to it, so a year rolling over in a date tag is a chart major exactly as it was before. The honest edge: for `6.0.0-beta13.1` and `9.1.2-alpine` the numeric part *is* a semver line, so the fallback understates a real minor there. That is the accepted trade — conservative by default; a chart that wants the minor earns a documented exception rather than a widened pattern.
+
+**Maximum, not replacement.** The chart jump is the *greater* of the chart's own classification and the app jump, so a value that becomes required stays a chart major under an app patch. Mechanically it is also what makes a grouped branch deterministic: the hook runs once per update and every call recomputes from the same base commit, so without the maximum the last call would win and `freesailarr`'s minor-among-patches group would take whatever level it happened to end on. The script only ever keeps a *higher* version than it computes, which is why repeated runs stay idempotent, and everything else is derived from the base commit for the same reason.
+
+`ci/run-bump-level-test.sh` holds every one of those cases (49 of them) against the version string the script writes — a wrong level is a valid version string, so the PR would go green and the only symptom would be a number that understates what it publishes.

The safeguard is not the absence of automerge, it is the branch protection: `main` requires a **review** and requires `validate-charts` to pass. `platformAutomerge` arms the PR on the forge, and Gitea merges it when *both* conditions are met, so an armed PR without a review simply sits there.

+- Semver rules for the chart part. **The chart jump is the greater of the chart's own classification and the jump of what it ships** (Gitea #128) — a maximum, never a replacement, so a value that becomes required is a chart major even under an app patch:

The full rule, the seven affected charts and what it deliberately does **not** oblige anybody to read are in "The version-bump hook" above.

 - **Documented exception — minecraft-server**: the only chart whose main image tag can be overridden, through `image.tagOverride` (#158, empty by default — the tag still comes from `appVersion`). `appVersion` is the tag and therefore fixes the JVM, and since chart 5.0.0 only the **newest** Java line is maintained out of this one directory; the older lines stay published as frozen chart versions (java8 and java17 at 4.0.0, java21 at 4.1.0) and never receive another change. Without the override, running an older JVM would mean installing a frozen chart and giving up every later fix — so the line is a decision at rollout time rather than a property of the chart. The override is named `tagOverride`, not `tag`, because it decouples the running image from the chart version, and it is deliberately outside Renovate's reach (`renovate.json5` tracks the `appVersion` in `Chart.yaml` and nothing else). The chart checks the pairing itself: the Java line of the **effective** tag against `minecraft.version`, failing the render with both values named — a mismatch used to install silently and only break the container afterwards.
 - Auxiliary images (sidecars, init containers, secondary workloads — e.g. the delegation nginx in matrix-synapse, guacd in patchmon, busybox init/consume images in paperless-ngx) are pinned via values instead of being hardcoded in templates, and their pinned versions are reviewed alongside every app-version update round.

+- `ingress.domain` and `ingress.clusterIssuer` (cert-manager) are `required` values **without defaults** — every installation sets both explicitly; they are the only values needed for a default install. `clusterIssuer` is required **only while `ingress.enabled`**: in Gateway mode the chart renders no certificate, and a value that is demanded and does nothing is precisely the defect guideline 12 exists to remove.
 - `ingress.className` selects the ingress class and defaults to `nginx`.
 - `ingress.annotations` takes optional extra annotations that are merged with the cert-manager `cluster-issuer` annotation the chart always sets.
 - The TLS secret is named `tls-<release>-<chart>-ingress`.
-- **Documented exception — homeassistant**: keeps its upstream-style flexible ingress values (host/tls lists, no required values); only its `ingress.className` default follows the standard (`nginx`, clearable to omit the field).
+- **A set of objects publishing ONE backend under hostnames the chart does not own is the third admissible shape, and it buys its secret name and its issuer per entry (Gitea #122).** Where a chart's app serves several tenants from one deployment and each wants a hostname of its own — `keycloak`'s realms are the case this was written for — the hostnames come as a values list and the chart renders one object per entry. Two convention rules do not survive that, and both deviations are **required**, not merely tolerated: the TLS secret name is a per-entry value with **no** default, because these hostnames already have certificates and several entries typically share one (a wildcard for a zone), so a derived `tls-<release>-<chart>-...` name per entry would ask cert-manager for a second certificate for a name that is already covered — one ACME order per hostname, for nothing; and the cert-manager annotation becomes **optional per entry**, because cert-manager keys a Certificate by the secret it writes, so of several objects naming one secret exactly one may carry it. That is the same deliberate omission the qBittorrent object in `freesailarr` makes, for the same reason, and it is why the secret name is required rather than defaulted: a chart that invents the name cannot also leave the issuing to somebody else. Annotations are per entry too, since the set is not uniform across the hostnames. Object names carry the **list index**, for the reason spelled out in the homeassistant bullet below — a hostname is not a dependable object-name fragment, so reordering the list renames and recreates the objects — and the entries render in **both** routing modes: a routing value in this repository is mode-independent by design, so a feature rendering in one mode only would silently disappear when an installation switched. That is also why the per-entry `parentRefs` exists, as the counterpart of the per-entry class.
+- **Documented exception — homeassistant, and it extends to the Gateway mode**: keeps its upstream-style flexible ingress values (host/tls lists, no required values); only its `ingress.className` default follows the standard (`nginx`, clearable to omit the field). Because it has **no `ingress.domain`**, it has **no `httpRoute.hostnames`** either — the second chart without that key after `freesailarr`, and the schema rejects it outright so the absence is enforced rather than merely intended. The hostnames and the paths come from `ingress.hosts`, which is therefore read in **both** modes and is not an Ingress-only value, and the chart renders **one `HTTPRoute` per entry** of that list with one rule per path of the entry. One object carrying several hostnames would be wrong rather than merely different: an `HTTPRoute`'s rules apply to *every* hostname of the object, and per-host paths are this chart's whole point. `ingress.className`, `ingress.tls` and `ingress.annotations` are not read in Gateway mode. Route names carry the entry's **index**, not its hostname (a hostname is not a dependable object-name fragment), so reordering `ingress.hosts` renames routes and therefore recreates rather than edits them — harmless, since a route holds no state and no certificate, but worth knowing before it looks like a bug. Its `pathType` default is the awkward one; see the `ImplementationSpecific` rule in the Gateway-API bullets below.
 - **A shared domain with sub-paths is the second admissible ingress shape.** Where a chart exposes several apps, they may either each take a host of their own or share one host and be told apart by path (`domain.tld/sonarr`, `domain.tld/radarr`, …) — one DNS name and one certificate for the whole bundle. The rules for the shared shape: the domain is a single value (`ingress.host`), each app's path is its own value defaulting to `/<app>`, the paths render in one Ingress object `<release>-<chart>-ingress` with the standard TLS secret `tls-<release>-<chart>-ingress`, and an app that carries a host of its own always wins and keeps its own object — so both shapes mix without extra values. An app that needs a per-path proxy annotation (`rewrite-target` is per **object**, not per path) gets its own object on the same host, repeating the same TLS secret name and **omitting** the cert-manager annotation, so that exactly one certificate is requested. Apps that cannot serve a base path must be rendered at `/` or refused with a `fail` — never rendered somewhere they provably cannot work.
-- **Documented exception — freesailarr**: the chart bundles several independently exposed apps in one pod, so it has **no** `ingress.domain`. It offers both shapes. By default each app carries its own `<app>.ingress.enabled` plus a required `<app>.ingress.host` (required only while that app's ingress is enabled and it is not on the shared domain) and renders its own Ingress object `<release>-<chart>-<app>-ingress` with its own TLS secret `tls-<release>-<chart>-<app>-ingress`. Setting the global `ingress.host` switches every app without a host of its own to the shared-domain shape under `<app>.ingress.path`; qBittorrent (no base path, needs a prefix-stripping rewrite) gets the extra object described above, and seerr as well as mediathekarr are pinned to `/` — mediathekarr because its UI links assets with root-absolute paths, which a rewrite cannot fix; with both of them on one shared host the duplicate-path guard fires and one of them needs a host of its own (its ingress is therefore off by default). `clusterIssuer`, `className` and `annotations` stay global defaults under `ingress.` and are overridable per app.
+- **The Gateway API is the second routing mode, and it is implementation-neutral by construction (Gitea #114).** A chart offers it through one values block, off by default:
+
+  ```yaml
+  httpRoute:
+    enabled: false     # counterpart to ingress.enabled
+    parentRefs: []     # the Gateway (name, namespace, sectionName) — a platform object
+    hostnames: []      # empty = [ingress.domain]
+  ```
+
+  The rules, each of which is load-bearing:
+
+  - **Only `HTTPRoute` with `parentRefs`.** No `Gateway`, no `gatewayClassName`, no certificate, and **no implementation-specific policy object** (`ClientSettingsPolicy`, `ClientTrafficPolicy` and their equivalents). That subset looks identical on nginx-gateway-fabric, Cilium, Envoy Gateway and Istio, and keeping to it is the whole reason the cluster's implementation can be chosen — or replaced — without touching the charts again. A policy object binds a chart to one implementation *and* to a CRD whose presence it cannot check. Class and certificate therefore move to the **platform**: they sit on the Gateway and its listeners, in `cluster-config`.
+  - **A value, not auto-detection.** `.Capabilities.APIVersions` is unreliable at template time, and an `HTTPRoute` without the Gateway-API CRDs fails at install time — so a chart that guessed would sometimes render an object the cluster rejects and sometimes silently render nothing.
+  - **Mutually exclusive with `ingress.enabled`**, enforced by a `fail` that names **both** value paths. Two paths onto the same Service under one hostname is a conflict at DNS level already; a migration runs over a **second hostname** (`httpRoute.hostnames` set explicitly while the Ingress keeps `ingress.domain`), never over parallel operation.
+  - **`parentRefs` is mandatory in Gateway mode**, enforced by a `fail` on the empty list. A route without a parent attaches to nothing and is simply inert — created, schema-valid, rejected by nobody, reported by nothing.
+  - **One source of truth for the hostname.** Empty `hostnames` means `[ingress.domain]`; two values that have to agree drift apart. `ingress.domain` is therefore read in Gateway mode too — it names the release's public hostname and is not an Ingress switch. After the sweep there are **three** shapes here, and which one a chart gets follows from its values rather than from taste: a chart with an `ingress.domain` falls back to it (the default, most charts); a chart with no `ingress.domain` whose names could not be attributed — `freesailarr` to one of ten apps, `homeassistant` to one host entry and therefore one set of paths — has **no `hostnames` key at all** and reads the names where they already live; and `rss-bridge` has the key as a **mandatory** value with no fallback, because it has no `ingress.domain` either but its names *are* unambiguous (one Service at `/`), while the `ingress.hosts` list it would otherwise reuse carries per-host `tlsSecretName` values that address nothing once TLS sits on the listener. The rule behind all three: a hostname list is admissible exactly where it can say what it belongs to, and reusing an Ingress structure whose other half is meaningless in this mode is not a saving.
+  - **`NOTES.txt` says which mode is active**, as `keycloak` already does for its cases, and names what the mode costs.
+  - **What has no counterpart, and must be said rather than rebuilt.** The Gateway API has no annotation channel for controller behaviour. `rewrite-target` has a real equivalent (the `URLRewrite` filter in a rule); **`proxy-body-size` has none** — an upload limit is implementation-specific policy, so a chart that depends on one must print in its Gateway-mode `NOTES.txt` that the limit is **not enforced** and has to be set at the Gateway. Charts that *set or recommend* one carry that disclosure: `calibre-web-automated`, `outline`, `paperless-ngx`, `zipline` since group 2, `bulwark` and `matrix-synapse` since group 3. `garage` *depends* on one without setting it: its `ingress.annotations` comment tells the operator to set `proxy-body-size: "0"` because ingress-nginx's 1 MB default truncates S3 uploads. Measured while sweeping group 1 — "sets no behaviour-bearing annotation" is not the same question as "needs none", and the sweep screens on the second one. `freesailarr` is the mirror image of `garage` and was measured in group 2: it sets no body-size annotation and needs none itself, but `ingress.annotations` is the only lever an operator has for one (qBittorrent takes torrent-file uploads), so its Gateway-mode `NOTES.txt` says that an annotation set there is gone. The same applies to auth annotations in front of an app with no login of its own: in Gateway mode that escape hatch does not exist in the chart at all (`cyberchef`, `searxng`), and so does any annotation a chart documents as its only lever for a response header (`bentopdf`: `X-Robots-Tag`).
+  - **Screen the LIVE object, not only the chart — group 3's lesson, and the generalisation of Gitea #118.** A chart can read as correct while the running system fills a gap of the chart with an annotation the **operator** set, and the Gateway mode drops `ingress.annotations`, so it drops the compensation with it. At #118 that was found *after* shipping, on `freesailarr`, where the annotation was a redirect nobody would have looked for in the chart. Group 3 measured it beforehand with read-only `kubectl` against the live cluster, and **four of its six charts carried such an annotation that the chart never sets**: `keycloak` (`proxy-buffer-size: 16k` and `proxy-buffers-number: 4`, on *both* of its Ingress objects), `matrix-synapse` (`proxy-body-size: 50m`, plus the `nginx.org/client-max-body-size` twin for the other nginx controller, plus a `configuration-snippet`), `stalwart` (the whole `enable-cors` block), `bulwark` (`proxy-body-size: 25m`). None of them appears in a `git grep` of this repository, because no template sets any of them — the only hits are the *documentation* that recommends two of them. **The measurement at the live object is part of the procedure, not a flourish**, and reading the chart alone is not a substitute for it.
+  - **And read the annotation's directive before calling it load-bearing.** `matrix-synapse`'s live `configuration-snippet` looks like exactly what Synapse's `x_forwarded` setting depends on — client IP for rate limiting, and federation. It is not: `more_set_headers` is the headers-more module's **output**-header directive ("Replaces (if any) or adds (if not any) the specified output headers"), the request-side one being `more_set_input_headers`. Those headers therefore go on the **response to the client**; Synapse never sees them, and what it reads with `x_forwarded: true` is the *request's* `X-Forwarded-For`, which ingress-nginx supplies itself. So the scariest-looking loss in group 3 is not a loss at all, and its `NOTES.txt` says in as many words **not** to re-create it at the Gateway and not to read its absence as the cause of a rate-limiting problem. The real loss on that chart is the body size. A reading of documented semantics, stated as such — nothing A/B-tested a running Synapse.
+  - **"No counterpart" is a claim to check against the pinned CRDs, and for CORS it is false.** `stalwart`'s live Ingress carries `enable-cors` with an allow-origin pointing at `bulwark`, the webmail chart in the *same group* — so losing it breaks a second chart, with a browser console error and nothing at all in the server's log. Measured by grepping the CRD set this repo pins (`ci/gateway-api-crds.sh`, gateway-api v1.6.3 standard channel): HTTPRoute's filters **do** carry a full `cors` field (GEP-1767) with `allowOrigins`/`allowMethods`/`allowHeaders`/`allowCredentials`/`maxAge`, and its documented level, verbatim from that CRD, is `Support: Extended`. `responseHeaderModifier` is in the same CRD and is **also Extended, not Core**. The chart still renders neither, for three reasons in order: it has **no CORS values** to render one from (the origin and the method list are the operator's, and the chart sets no CORS annotation in Ingress mode either, so a filter would exist in Gateway mode only — an asymmetry that is its own defect and its own piece of work); **Extended support is not support**, since a rejected route is rejected *whole* (the reasoning #119 reached for `statusCode`) and the observed failure is quieter still — Cilium accepts `filters.type: CORS` and forwards the preflight upstream anyway, i.e. `Accepted: True` with the behaviour absent; and **half a CORS is worse than none, with the translatable half being the useless one here** — the browser's preflight must be answered *by the gateway* (the CORS filter's own contract forbids passing it upstream) and a bare header filter cannot do that, while this installation's allowed headers include `Authorization`, which makes **every** request preflighted. Hence: configure CORS at the Gateway with that implementation's own support *before* moving the host, and test from the browser — `curl` sends no preflight, so it passes while the webmail fails.
+  - **`rewrite-target` is the one place where the Gateway API is less machinery than what it replaces, not a translation of it.** `rewrite-target` applies per **Ingress object**; a `URLRewrite` filter applies per **rule**. A chart serving several apps under one host, one of which needs its prefix stripped, therefore needs a *second* Ingress object for that app — which then has to repeat the other object's TLS secret name, omit the cert-manager annotation so only one certificate is requested (conditionally, for the case where no other object renders), and match on an `ImplementationSpecific` regex path whose capture group the rewrite refers to. In Gateway mode all four disappear: one route, one rule per app, the filter on one rule, a plain `PathPrefix`. Measured on `freesailarr` in group 2, and after group 3 it is still the **only** chart here with a `rewrite-target`: `bulwark` was listed as the second one by #114 and by this file, and it has none — see the HTTPRoute-test section for why the string occurs in that chart four times without the annotation ever being set.
+  - **`pathType: ImplementationSpecific` has no counterpart either, and it is a chart *default* in one place.** Ingress offers `Exact`, `Prefix` and `ImplementationSpecific`; the Gateway API offers `Exact`, `PathPrefix` and `RegularExpression`. The first two map cleanly. `ImplementationSpecific` means "ask the controller", so nothing preserves it — and it is the default in `homeassistant`'s `ingress.hosts`, the one chart keeping upstream's flexible host list. The rule group 3 settled on, and the split is not tidiness: on the path `/` it is rendered as `PathPrefix`, because every controller treats a root `ImplementationSpecific` path as a prefix match and the chart's own default therefore works in Gateway mode unchanged; on **any other path the render aborts**, because in ingress-nginx an `ImplementationSpecific` sub-path is a **regex** and `PathPrefix` is not one, so mapping it silently would change how the path matches while the render stayed green — the #118 class of defect exactly. `RegularExpression` is deliberately not offered as an escape hatch: its support level is Implementation-specific, which is what the first rule above forbids.
+  - **A value derived from `ingress.enabled` is a second thing the sweep has to look for, and it is not visible in the Ingress template.** Gateway mode sets `ingress.enabled: false` *by construction*, so any value computed from it flips — and where it stood for "is there a TLS-terminating proxy in front" or "is this app published at all", the flipped value is wrong while nothing fails. Two finds so far, both fixed by one helper reading `ingress.enabled OR httpRoute.enabled` rather than by a new value:
+    - `sure` (group 1), whose `RAILS_ASSUME_SSL`/`RAILS_FORCE_SSL` would have gone `false` with TLS terminated at the Gateway: insecure cookies, no HSTS, `http://` links, green pod. Helper `sure.publishedOverTls`.
+    - `freesailarr` (group 2), whose `freesailarr.sharedIngressApps` was gated on `ingress.enabled` and is read by the `<APP>__SERVER__URLBASE` environment variables as well as by the routing objects. In Gateway mode that list would have come out **empty**, so Radarr, Sonarr and Prowlarr would have been told no base path while their routes served them under `/radarr`, `/sonarr`, `/prowlarr` — a UI whose assets and API calls are linked at the host root, behind a Ready pod. The two guards living in that helper (seerr/mediathekarr only at `/`, no duplicate paths on the shared host) would have gone unenforced in that mode for the same reason. Helper `freesailarr.published`.
+    - `ytdlp-web-player` (group 3), the one this file had listed as still open, and the find with the sharpest consequence. Its `ytdlp-web-player.validate` guard — which refuses to publish the application and the bundled oauth2-proxy on the **same host** — was gated on `ingress.enabled`, so in Gateway mode it went silent. **And that guard is needed more in Gateway mode, not less.** In Ingress mode ignoring it fails loudly: ingress-nginx's admission webhook rejects the second Ingress and the Fleet bundle lands in `ErrApplied`. In Gateway mode **the webhook never fires** — it compares Ingress objects with Ingress objects, and an `HTTPRoute` is a different kind — so nothing rejects anything, both objects stay valid, and one hostname is served over two data paths that are *not* equivalent: the proxy's Ingress goes through **authentication**, the chart's `HTTPRoute` goes straight to the application. Which one a client reaches depends on what DNS resolves to, so it is an authentication bypass that comes and goes with a record, reported by nothing. Helper `ytdlp-web-player.published`, and the Gateway-mode abort carries its own message saying exactly that.
+
+    All three are now closed, and the screen was run over all six charts of group 3 rather than only the suspected one — and over `rss-bridge` as the last chart, where it came back **clean**: outside its Ingress template the only readers of an ingress value are `NOTES.txt`, which knows its own mode, and the `rss-bridge.tlsGroups` helper, which is called only from behind `ingress.enabled`. The application takes no base URL and no hostname in its environment, so there is nothing to compute from the switch and no `published` helper is needed. **A clean result is worth recording too**: the screen's value is that it is run, not that it always finds something, and "this chart needed no helper" is a measurement rather than an omission.
+  - **A subchart does not come along, and that has to be said where somebody will look for it.** `ytdlp-web-player`'s oauth2-proxy dependency has **no Gateway-API support** and this repo does not patch upstream charts (see "Chart dependencies"), so it renders an Ingress or nothing. In the *recommended* configuration — the proxy in the data path, owning the host, the chart's own routing object off — the object that publishes the release is therefore **the subchart's Ingress in both of the chart's modes**, and setting `httpRoute.enabled` there changes nothing about how the host is served. The chart's own route is for the proxy-disabled case or for the application on a host of its own, which is the documented unauthenticated bypass. Stated in the template header, in `values.yaml`, in the schema and in the proxy branch of `NOTES.txt`, because an operator migrating hosts would otherwise set the value and wonder why nothing moved.
+  - **CI**: either the chart's install-test fixture installs in Gateway mode, or it gets a render-only overlay at `ci/httproute/<chart>.yaml` — otherwise `ci/run-httproute-match-test.sh` is green over nothing for it, which that test fails on. An overlay for a multi-app chart has a second job: it must enter **every** shape the template has, or the branch nobody exercised is the one that breaks. `ci/httproute/freesailarr.yaml` gives one app a host of its own so both the shared-host route and the per-app route render.
+
+  Reference implementation: `template-chart/templates/xxx.httproute.yaml`. Pilot: `cyberchef`. Group 1 — the charts rendering one Ingress with no behaviour-bearing annotation — followed: `bentopdf`, `garage`, `patchmon`, `rallly`, `searxng`, `sure`, `urlaubsverwaltung`, `voucher-vault`. Group 2 — the charts whose behaviour hangs off an nginx annotation — followed: `calibre-web-automated`, `outline`, `paperless-ngx`, `zipline` (all four `proxy-body-size`) and `freesailarr` (`rewrite-target`). Group 3 — the special shapes: `homeassistant`, `keycloak`, `bulwark`, `matrix-synapse`, `stalwart`, `ytdlp-web-player`. **`rss-bridge` finishes the sweep**, as the twenty-second and last chart: 22 charts carried an Ingress template and 21 an HTTPRoute template, and the difference was exactly this one. It had been held back as frozen for changes by #51 — a runner defect, not a property of the chart — and the earlier claim that **#114 could not be closed while #51 was open no longer holds**: the maintainer lifted that freeze, so #114 closes with the chart converted while **#51 stays open**, since the runner defect is worked around for this purpose rather than fixed. Its shape: one `HTTPRoute` carrying **all three** of its hostnames, because nothing differs per host (every name serves the same Service at `/`, measured on the live Ingress), so `spec.hostnames` as a list is the whole answer and a second object would repeat one rule. It is also the only chart of the sweep whose Gateway branch has **no loss to document** — its live Ingress carries no `nginx.ingress.kubernetes.io` annotation at all, so the group-3 screen came back empty. Its install-test, red since the move (#51), **went green in the conversion PR** with a pod `Ready` in 22 s and no `Permission denied`; since that PR's rendered defaults are byte-identical to `origin/main`, the chart is ruled out as the cause and the runner is the implicated layer. That green covers Ingress mode, which is what the fixture installs, so the Gateway mode of this chart is render-only like every other chart's.
+
+  **Three of #114's descriptions of the group-3 shapes did not survive contact with the charts**, and the corrected list is worth having here because it is the one somebody will copy from:
+
+  | #114 said | Measured |
+  |---|---|
+  | `keycloak` and `bulwark` have **two** Ingresses each | `keycloak` has two (public and admin hostname) and gets two routes. **`bulwark` has one.** |
+  | `bulwark` is the second `rewrite-target` chart | It has none and cannot have one — `NEXT_PUBLIC_BASE_PATH` is compiled into its bundle, so it cannot be served under a sub-path and its route is one rule at `/`. The grep that produced the claim hit the chart's *refutations* of the idea. |
+  | `matrix-synapse` renders its Ingresses **in a loop over several apps** | That is `freesailarr`. `matrix-synapse` renders **one** Ingress object with **two host rules** — the homeserver at `/` and the delegation nginx at `/.well-known/matrix` — which has to become **two** `HTTPRoute` objects, because `spec.hostnames` applies to the whole object and these two want different paths and different backends. |
+  | `stalwart` renders **per node group** | Its Services and StatefulSets do; the routing object does not and must not. One Ingress targets exactly `ingress.nodeGroup`'s own http Service, and the route keeps both of that template's guards — the management surface is not safe to spread over a group that may not run the management tasks. |
+
+  Three further group-3 specifics: **`keycloak`'s admin Ingress did not hang off `ingress.enabled`** before the sweep (`ingress.admin.enabled` gates it, and that value is not an Ingress switch — it also sets `KC_HOSTNAME_ADMIN`), so `ingress.enabled: false` did not mean "no Ingress" and the object would have gone on claiming the admin host next to the admin route; it is gated on both now, which leaves the default render unchanged and only alters a combination that could not be coherent. `httpRoute.admin.parentRefs` falls back to `httpRoute.parentRefs` exactly as `ingress.admin.className` falls back to `ingress.className`, because **"which data path" is a property of the Gateway in this API, not of the route** — an internal Gateway there is what an internal ingress class is in the other mode. And **`stalwart` is the only chart in the sweep that still renders a `Certificate` in Gateway mode**: its mail certificate covers STARTTLS on 25 and implicit TLS on 465/993, which pass through neither an ingress controller nor a Gateway, so `ingress.domain` stays required there and the object must not be removed as part of a migration — deleting it drops SMTP and IMAP back to a self-signed certificate while every Kubernetes object stays green.
+
+  `garage` was one of #114's named special cases and was done in group 1: it ships `ingress.enabled: false`, so both of its modes are off by default and its route is exercised by a render overlay rather than by the install-test, which keeps its Ingress. `homeassistant` is the same case and the same treatment — its `ingress.enabled` default is `false` too, so group 3's overlay for it **adds** coverage the install-test never had rather than trading one object for another. `paperless-ngx` was the one chart in the repository that still rendered its Ingress **unconditionally**; group 2 gave it an `ingress.enabled` switch defaulting to `true`, because without a second value path there is nothing for the mutual-exclusion abort to name and the `required()` on `clusterIssuer` would have kept demanding a value the Gateway mode does not use.
+
+  **One place where the Gateway API is the better fit, found in group 3**: Matrix delegation. The server name is normally an apex domain that already serves a website, and under ingress-nginx two Ingress objects cannot both claim one hostname — the admission webhook rejects the second — which is why `matrix-synapse` has to carry the `/.well-known/matrix` rule *inside* its own single Ingress object. HTTPRoutes attached to the same listener for the same hostname are **merged** by the implementation, longest match winning, so in Gateway mode that route can sit beside whatever owns the apex without either side knowing about the other.
+- **Documented exception — freesailarr, and it extends to the Gateway mode**: the chart bundles several independently exposed apps in one pod, so it has **no** `ingress.domain` — and therefore **no `httpRoute.hostnames`** either, the only chart without that key. A chart-global list of hostnames could not say which of the ten apps it belonged to, so the hostnames stay where they already are, in `ingress.host` and `<app>.ingress.host`; both are read by both modes and neither is an Ingress switch. In Gateway mode the per-app shape renders one `HTTPRoute` per app (`<release>-<chart>-<app>-httproute`) and the shared shape exactly one (`<release>-<chart>-httproute`) with one rule per app — qBittorrent included, since its prefix-stripping rewrite is a per-rule filter there, and it is the one app contributing **two** rules: the rewrite plus a 301 from the bare, slashless prefix to the slashed form (Gitea #118). Without that redirect the slashless path is stripped to `/`, answered 200, and the page's relative links resolve to the root of the shared host — a different app. **The Ingress mode does not render it and cannot**: nginx offers only a `configuration-snippet` annotation, which is ignored unless the controller runs with `allow-snippet-annotations=true` (off by default since ingress-nginx 1.9, and it means accepting annotation risk level `Critical`), so the chart documents the snippet in `values.yaml` instead of shipping a no-op. It is the one place where the Gateway mode closes a gap rather than merely replacing machinery. It offers both shapes. By default each app carries its own `<app>.ingress.enabled` plus a required `<app>.ingress.host` (required only while that app's ingress is enabled and it is not on the shared domain) and renders its own Ingress object `<release>-<chart>-<app>-ingress` with its own TLS secret `tls-<release>-<chart>-<app>-ingress`. Setting the global `ingress.host` switches every app without a host of its own to the shared-domain shape under `<app>.ingress.path`; qBittorrent (no base path, needs a prefix-stripping rewrite) gets the extra object described above, and seerr as well as mediathekarr are pinned to `/` — mediathekarr because its UI links assets with root-absolute paths, which a rewrite cannot fix; with both of them on one shared host the duplicate-path guard fires and one of them needs a host of its own (its ingress is therefore off by default). `clusterIssuer`, `className` and `annotations` stay global defaults under `ingress.` and are overridable per app.

 - Every workload container offers an additive `env` value block, appended to the env entries the chart always sets.
 - Entries are rendered through `tpl` (so values may contain Helm templating) and support the `value`, `secretKeyRef` and `configMapKeyRef` forms (pattern: `template-chart/templates/xxx.deployment.yaml`).
+- **`| quote` on the rendered `value`, and on the `name`/`key` of the ref forms, is part of the pattern and not cosmetic.** An env value is typed `string` by Kubernetes, so a value of `"true"` or `"0755"` rendered bare becomes a YAML bool or integer and the API server rejects the whole manifest with `cannot unmarshal bool into Go struct field EnvVar.value of type string` — after a perfectly green render. A value beginning with `*` is worse in the other direction: it aborts the render with a YAML error naming the template, while the operator's own value appears nowhere in the message, and quoting it in the values file does not help. **The rule is held by `ci/run-yaml-scalar-render-test.sh` on every PR** (Gitea #11/#112), which is also how the count below is known rather than assumed: `template-chart` carries the rule in a comment claiming "every chart in this repo quotes here", and **six still do not** — `matrix-synapse`, `minecraft-router`, `minecraft-server`, `rallly`, `satisfactory`, `teamspeak-server`. They are green only because no fixture of theirs sets a hostile value; bringing a chart to the quoted form is a **major** bump for it, since it changes rendered output for values that currently work.
 - **Additive means additive: an entry repeating a name the chart already sets does not replace it, and what the pair does depends on when it arrives.** At install both entries reach the pod and the later one — the user's — wins. On an *existing* release the same entry is lost: Kubernetes merges `env` by name, the pair collapses to the chart's own value, and `helm upgrade` still reports success. Measured on `urlaubsverwaltung` (helm 3.19.0, Kubernetes 1.35): `helm get manifest` shows the variable twice while the live Deployment shows it once, carrying the chart's value. The failure mode is silence, so a chart whose `NOTES.txt` tells operators to override one of its own variables has to say that the override only takes at install time — and that a green upgrade proves nothing, the value belongs read back off the Deployment.

@@ -389,6 +578,9 @@ These guidelines are **binding for every current and future chart** in this repo
 - Implemented via a per-chart `<chart>.replicas` helper in `_helpers.tpl` (reference in `template-chart`); the helper uses an explicit nil check (`kindIs "invalid"`) because Helm's `default` would swallow an explicit `0`.
 - **A chart whose default is more than one replica ships a `PodDisruptionBudget`** — `policy/v1`, named `<release>-<chart>-pdb`, `minAvailable` as a value (default `1`), selector matching the workload's `app` label. `keycloak` (Gitea #83) is the first and sets the convention. The reason it is a rule and not a per-chart taste: a node drain is the most common reason a pod moves — it is what a node upgrade does — and without a budget the drain is free to take every replica at once, so the second replica buys nothing against the failure it was added for.
 - **And it is rendered only while the effective replica count is `>= 2`.** `minAvailable: 1` with exactly one replica forbids every voluntary eviction, so `kubectl drain` blocks forever on a pod nothing may move — and the message names the PDB, not the replica count, which sends the reader to the wrong file. The same applies to `scaleDown: true`, where there are no pods and the object would describe a promise about nothing. So the condition is on the **computed** replica count (the `<chart>.replicas` helper), not on the raw value, and `NOTES.txt` prints which of the two happened rather than leaving it to be inferred from `kubectl get pdb`.
+- **A chart whose replicas are a property of a *group* gets one PDB per group, with that group's own count** (Gitea #96; `stalwart` is the first, one node group per cluster role). The condition above then applies per group — with `full: 2` and `mx: 1` exactly one object is rendered — and `NOTES.txt` lists the outcome per group rather than once for the release. The name carries the group (`<release>-<chart>-<group>-pdb`), and so does the selector.
+- **A budget without a distribution rule is half an answer.** The PDB keeps a drain from taking every replica at once; it says nothing about where the replicas were put in the first place. Where a chart's replicas are meant to survive the loss of a node, it also offers a **per-group switch that renders the `topologySpreadConstraints` entry itself, with a selector the chart fills from its own pod labels** — never one the operator writes, because a spread constraint whose selector matches no pod is trivially satisfied and distributes nothing, with a green rollout and no message. `stalwart` sets the convention: `nodes.<group>.spreadAcrossNodes` (default `true`, gated on the same computed `>= 2`), `maxSkew: 1` on `kubernetes.io/hostname`, `whenUnsatisfiable: DoNotSchedule` so the distribution is a promise rather than an effort, and a generic per-group pass-through (`affinity`, `nodeSelector`, `tolerations`, `topologySpreadConstraints`) for everything the switch does not cover. Three traps come with it and all three belong in the chart's `values.yaml`: `nodeAffinityPolicy: Ignore` must be set **explicitly** (its API default is `Honor`, under which a narrowing `nodeSelector` shrinks the set of counted domains until both replicas fit in one, giving skew 0 — co-location with no `Pending`, no event, and a selector that is *correct*, so no CI check can see it); that field is **beta** and is pruned without a word below Kubernetes 1.26, which brings that exact gap back; and the replica ceiling is **a rule, not a number** — as many replicas per group as there are schedulable workers, because `nodeTaintsPolicy` defaults to `Ignore` and control-plane domains therefore hold the minimum at 0 permanently. That ceiling comes from `nodeTaintsPolicy` and is **not** a consequence of setting `nodeAffinityPolicy`; the two are documented separately for that reason. A user entry colliding with the chart's own on `(topologyKey, whenUnsatisfiable)` **aborts the render naming both values**, because the two alternatives are an API error pointing at a list index and a silent merge over `patchMergeKey: topologyKey` that drops one selector and goes green.
+- **Both selectors are held against the rendered pod labels on every PR** by `ci/run-selector-match-test.sh` — see "Selector-match render test" above. Needed because the shared-helper rule above is a convention, and a convention is the thing a copy breaks.

+### 15. NetworkPolicies (#5)
+
+**Every chart renders a `NetworkPolicy`, and `networkPolicy.enabled` defaults to `true`.** Reference implementation: `template-chart/templates/xxx.networkpolicy.yaml`. The default is the decision the whole convention rests on — a policy that ships switched off is reached only when somebody remembers to switch it on, and then the issue is closed while nothing is filtered. Adding one to an existing chart is therefore a **major** bump.
+
+**What the object is: a ceiling on reachability, not an authentication layer.** Three limits are real and worth having, and for most charts here the first two are where all of the value sits:
+
+1. **Only the declared ports are reachable at all.** Whatever else the process binds — a debug listener, a management interface the image opens by default, a port that appears in the next app version — is blocked without anyone having to notice it exists.
+2. **Egress is capped by port**, so a compromised pod cannot open arbitrary outbound connections.
+3. **Ingress is capped by source for every port no network probe touches.**
+
+#### The four port classes, and why the class decides the rule
+
+Every port of a workload falls into one of four, and this is the part to get right before writing anything:
+
+| Class | Rule | Why |
+|---|---|---|
+| **probe path** — a port a *network* probe addresses | **no `from`** by default; restricted once `networkPolicy.probeSources` is set | the kubelet probes from the IP of the **worker node running the pod**, an address no chart can know. A guessed CIDR that misses it drops every probe: the pod never becomes `Ready`, the rollout times out, and the symptom reads as a broken application rather than as a policy |
+| **public** — published by a `NodePort` Service | **no `from`** | the senders are on the internet and, after NodePort masquerading, the source address is a cluster node anyway. A source selector could only ever be a list of node IPs — a restriction in appearance and a maintenance trap in fact |
+| **closed** — no probe, not published outside | own namespace + `allowedNamespaces` (+ the ingress controller where the chart routes HTTP there) | this is the only class that yields a *real* inbound restriction, and the charts that have one are the ones whose probes use a *different* port: `keycloak`'s 8080, `garage`'s s3 and web, `minecraft-server`'s RCON, `teamspeak-server`'s query interface |
+| **self** — a cluster bus between a release's own replicas | `podSelector` only, no `namespaceSelector` | the narrowest rule the object can express: "these labels, in this namespace". `keycloak`'s jgroups, `garage`'s rpc. Note that `policyTypes: Egress` means the **outbound** side needs its own rule, or the bus is open one way and the cluster never forms while every node looks healthy |
+
+**`exec` probes are not in the probe class**, and the distinction is load-bearing rather than pedantic: an `exec` probe runs inside the container through the kubelet's runtime and puts no packet on the network, so there is no kubelet traffic to accommodate. That is the entire reason `valkey` and `minecraft-server` have the tightest policies in the repository — every port restricted by source, no `probeSources` value at all — and every HTTP-probed web app has a looser one.
+
+#### Values
+
+`networkPolicy.enabled`, `.allowedNamespaces`, `.probeSources`, `.ingressController`, `.egress.extraPorts` — and a chart ships **only the ones that reach a rule**. A chart may add a **named** egress switch where a port depends on something the values cannot see: `paperless-ngx`' `.egress.mailImport` opens IMAPS `993`, off by default, because its mail accounts are rows in its own database and no value says whether a release fetches mail. The bar for one of those: it names what it opens, and it is **not** a second switch for a port some *other* value already decides — that is why the Tika/Gotenberg rule stayed gated on `paperless.files.tikaGotenberg.enabled` and got no policy switch of its own. Two values that can drift apart re-arm the outage the rule was fixed for. A value that silently does nothing is worse than one that is absent, because it reads as a control: `samba` and `satisfactory` carry `enabled` alone (every inbound rule is open to any source), and `teamspeak-server` has `allowedNamespaces` but no `probeSources`.
+
+**No chart ships `allowedNamespaces` pre-filled, ever.** A chart that named `mc-router`, or `paperless-jk`, or `stalwart` in its defaults would be baking in an assumption about *this* cluster's namespace layout — which is exactly the kind of claim a chart cannot keep true. So the default is the empty list and the chart is **restrictive**; filling it is the **deployment adaptation**, made where the namespace layout is actually visible. That is why a sweep like this produces a list of release-side one-liners: those are the expected procedure, not a defect list, and the breaking-change major on each chart is what announces them.
+
+`ingressController` is the one exception to that, and only because it names a **cluster component** rather than a tenant: its default is measured below, and it is still overridable.
+
+`ingressController` is a separate value with two keys rather than a line in `allowedNamespaces` for one reason: **its two selectors render as one `from` entry, which is an AND** — those pods in that namespace. Written as two list entries they would be an OR, and putting `kube-system` into `allowedNamespaces` instead would open the port to every pod in the cluster's own namespace. Its default is **measured, not assumed**: `ingress-nginx` is gone from this cluster, the only `IngressClass` is `traefik`, and the controller is the DaemonSet `rke2-traefik` in `kube-system` — which also serves the Gateway API here, so one source covers the Ingress and the HTTPRoute path alike. `ingress.className` says nothing about it: a class names an implementation, not the pods the traffic comes from.
+
+#### What these policies do not do — and it belongs in every chart, not just here
+
+- **Egress is coarse: by port, never by destination.** A `NetworkPolicy` matches `ipBlock` CIDRs and pod/namespace selectors and **never hostnames**, so "only to the database host" is not expressible at all. This cluster's CNI is Canal (Flannel plus Calico for policy) and has no FQDN rule; Calico's `GlobalNetworkSet` could express one but would bind every chart to Calico — the same argument that kept implementation-specific objects out of the Gateway-API sweep (#114) — so it is **not used**. This is a limit of the object, and each chart names what it costs *that* chart.
+- **Most dependency ports are the standard ones, not the configured ones.** Databases, caches and OIDC issuers arrive as connection URLs or as fields inside 1Password items the charts never parse, so a chart cannot know where its dependency listens and cannot validate a guess. A dependency somewhere else is **blocked**, and `networkPolicy.egress.extraPorts` is the escape hatch. The exceptions are the two charts that hold their ports as values and therefore derive them: `keycloak` (`keycloak.db.port`) and `stalwart` (`dataStore.postgres.port`, `externalServices.*.port`); `minecraft-router` derives its backend ports from its own routing table the same way.
+- **The probed port stays open inside the cluster by default.** For a single-port web app that means the policy is a port and egress ceiling, not pod-level isolation — say so in the chart rather than letting the object imply otherwise.
+- **A subchart's pods are not covered.** The policy selects this chart's workload by label; a subchart renders its own pods with its own labels. `ytdlp-web-player`'s oauth2-proxy is the sharpest case — with the proxy on, the pod that actually faces the Ingress is unrestricted in both directions, and an upstream chart is consumed as it comes (section 14). `paperless-ngx`' `valkey` is the opposite: it brings its own, tighter policy. Name which case a chart is in.
+- **And a policy is only a boundary where the CNI enforces one.** Unenforced, the API server still accepts it and nothing is filtered, so everything reads as configured. Verify by connecting from an unrelated namespace, not by reading the value.
+
+#### Where the convention says "Ingress only"
+
+`policyTypes` names only what there is something to restrict. `valkey` established it for a workload that opens **no** outbound connection: an egress rule would constrain nothing while making the object look stricter than it is. Three charts now invoke the same rule in the other direction, for outbound traffic nobody can enumerate — and each argues it in its own file rather than inheriting a blanket excuse:
+
+- **`homeassistant`**: outbound traffic is the union of every integration an operator enables (mDNS and SSDP discovery, MQTT, a Zigbee or Z-Wave bridge on whatever port its firmware chose, ESPHome, printers, speakers, inverters, cloud APIs, NTP). A cap would protect little — the devices sit on the node's own LAN — and would break integrations one at a time, months apart, each looking like a flaky device.
+- **`satisfactory`**: Steam's content delivery is not a pinnable port set, *and* this is the one chart with no install-test at all (`ci/excluded-charts.txt`), so an egress cap here would be the only one in the sweep with no empirical check behind it, on the chart whose correct port set is least knowable.
+- **`gotenberg`** goes the other way and is worth contrasting: it *keeps* a DNS-only cap deliberately, because it drives a headless Chromium and 3000 is its probe port — so an egress rule for 80/443 would turn a service the whole cluster can POST to into an SSRF pivot. The price is that HTML conversion silently loses remote assets, which is written into the chart because nothing will alert on it.
+
+#### Mechanics
+
+- **Pod ports, never NodePorts.** A `NetworkPolicy` is evaluated at the pod's network interface, *after* kube-proxy has translated a NodePort to the `targetPort`. `30025` where the pod listens on `25` matches nothing: accepted, strict-looking, and blocking every inbound connection instead. The render test asserts this mechanically against the selected pod spec's `containerPort`s.
+- **And pod ports, never Service ports — in `egress` too (#136).** The same destination NAT runs on the way *out*: kube-proxy rewrites a ClusterIP's address and port **before** the egress policy is evaluated, so the policy sees `podIP:targetPort` and never `clusterIP:port`. An egress rule therefore names the **pod** port of its destination, and a Service port only ever matches by coincidence — wherever `port` and `targetPort` are the same number, which is the case for `5432`, `6379`, `993` and `443` and is why this mistake stayed invisible until a chart dialled a Service that forwards `80` to `9998`. It was argued the other way in `paperless-ngx` (*"an egress rule names the port on the destination as the client dials it, and the client dials the Service"*), shipped, and cost an outage. **The tell is the symptom:** a dropped packet runs into a **timeout**, a missing listener answers `connection refused` — so a timeout where the service demonstrably exists is a policy question, and no Kubernetes error will say so. For a destination *outside* the cluster there is no NAT in the path and the port dialled is the port to name; the deciding question is the DNAT, not the direction.
+- **Protocol as well as number.** `teamspeak-server`'s voice port is UDP and `satisfactory`'s game port is both — a TCP-only rule on either is accepted, looks complete, and drops the traffic that actually arrives.
+- **`kubernetes.io/metadata.name`** is set by Kubernetes itself on every namespace (≥ 1.21), so namespace selectors need no labelling work on namespaces the chart does not own — and get no typo protection either.
+- **Never `from: []`.** It allows everything, identically to having no key, while reading as a restriction. Write no `from` where open is meant and say so in a template comment.
+- **Reasoning goes in Go template comments, not `#` comments.** A `#` comment is part of the rendered object: it travels into the cluster, appears in `helm get manifest` and `kubectl get -o yaml`, and lands in every release diff. The render test fails on a rendered `#`. One second-order trap, found while writing the reference implementation: prose inside a template comment must not spell out the comment's own closing delimiter, or the parser ends the comment early and the rest is emitted as manifest content — the render then fails with `did not find expected node content`, pointing at the template and not at the sentence.
+- **A conditional `containerPort` needs a conditional rule.** `minecraft-server`'s RCON port is rendered only when `server.rcon.enabled` is true; a rule without the same gate names a port the pod does not declare, and the render test rejects it.
+- **A policy applies to traffic that arrived through a Service, and that is why the `ingressController` rule works at all.** A `NetworkPolicy` is evaluated at the pod's network interface and a Service is only destination NAT, so going through a ClusterIP does not exempt anything. What the Service *does* change is the **source address**: pod → ClusterIP → pod **preserves** it, which is what lets a `podSelector` match the Traefik pod or a `namespaceSelector` match a consumer's namespace. **And what it also changes is the destination port, which is the half #136 was paid for:** "a Service is only destination NAT" is exactly why an *egress* rule has to name the pod port — the same sentence, finished in the other direction. It was written here before the wrong rule was written there; the information was present and the conclusion was missing, which is the sort of gap no check catches. Traffic from outside through a `NodePort` with the default `externalTrafficPolicy: Cluster` is **masqueraded to a node**, which is why those rules cannot be restricted by source at all and are left open instead (`stalwart`'s template carries that second half; the first half is the load-bearing one).
+
+#### The one cluster setting this convention depends on and does not control
+
+**Traefik must not run with `hostNetwork`.** Measured on 2026-10-14: the `rke2-traefik` DaemonSet has no `hostNetwork`, and its pods carry real pod IPs (`10.42.3.120`, `10.42.4.94`, `10.42.0.187` — the pod CIDR is `10.42.0.0/16`, nodes are on entirely different addresses). **Only because of that does a `podSelector` match it**, and the `ingressController` value is built on exactly that.
+
+If Traefik were ever switched to host networking, its pods would share the node's network namespace, they would no longer be selectable as pods, the `ingressController` entry would match nothing — and **every web chart in this repository would go dark at once**, in the restricted configuration. The policies would still be accepted, still read as correct, and deny all web traffic.
+
+This is a dependency on a cluster setting this repository does not own, in the same class as the `--enable-certificate-owner-ref` case from #126: nothing here can detect it, and nothing here can fail usefully on it. It is written down in both places someone would look — here, and in the header of `template-chart/templates/xxx.networkpolicy.yaml` — so that whoever changes the ingress controller's networking finds the consequence attached to the thing they are changing. The symptom to recognise: every chart's web traffic stops at once while every pod stays `Ready`, because the probe path does not go through the controller.

+NetworkPolicy for apache-tika (Gitea #5).
+
+Apache Tika here is a cluster-internal service: the chart creates no Ingress at
+all, and its only consumers are other pods - paperless-ngx points at
+http://<service>.<namespace>.svc.cluster.local for text extraction.
+
+THAT MAKES THE SOURCE QUESTION THE INTERESTING ONE, AND IT HAS AN AWKWARD
+ANSWER. 9998 is the port all three probes address, so it cannot be restricted
+by source without the worker node's IP - and this chart's consumers live in
+OTHER namespaces (paperless-cmk, paperless-jk, paperless-tb in this cluster).
+So an operator who narrows probeSources has to list those namespaces in
+allowedNamespaces in the same breath, or every document extraction stops. That
+is written into values.yaml and NOTES.txt rather than left to be discovered.
+
+Egress is DNS only. Tika extracts text from documents it is handed; it fetches
+nothing, and a text extractor that can reach the internet is a worse thing to
+hand an untrusted document to.
+
+WHAT THIS OBJECT IS: a ceiling on reachability, not an authentication layer.
+Only the ports declared below are reachable at all - whatever else the process
+binds, now or after the next app update, is blocked without anyone having to
+notice it exists.
+
+WHAT IT IS NOT:
+  - EGRESS IS COARSE. A NetworkPolicy matches CIDRs and selectors and NEVER
+    hostnames, so "only to the database host" cannot be expressed at all. This
+    cluster's CNI is Canal (Flannel plus Calico for policy) and has no FQDN
+    rule; Calico's GlobalNetworkSet could express one but would bind this chart
+    to Calico, the same argument that kept implementation-specific objects out
+    of the Gateway-API sweep (#114). Each egress rule therefore permits its
+    PORT to any destination.
+  - NOT A BOUNDARY WHERE THE CNI DOES NOT ENFORCE ONE. An unenforced policy is
+    accepted by the API server and filters nothing, so everything reads as
+    configured while nothing is filtered.
+  - THE REASONING IS IN TEMPLATE COMMENTS, not in "#" comments: those are part
+    of the rendered object, travel into the cluster and appear in every release
+    diff. ci/run-networkpolicy-test.sh fails on a rendered "#".
+
+THE PORT NUMBERS BELOW ARE POD PORTS, NEVER NODEPORTS. A NetworkPolicy is
+evaluated at the pod's network interface, after kube-proxy has already
+translated a NodePort to the targetPort, so a NodePort number here would match
+nothing while looking strict - and, being the only rule for that port, would
+block every inbound connection instead. ci/run-networkpolicy-test.sh asserts
+every port here against the containerPorts of the pod spec this policy
+selects.

+None of that is rebuilt here - a policy object would bind the chart to one
+implementation. NOTES.txt says so in this mode instead of leaving it to be

+NetworkPolicy for bentopdf (Gitea #5).
+
+BentoPDF is a browser-side PDF tool: nginx serves the bundle, the documents are
+processed in the visitor's browser, and the chart has no secrets and no
+volumes. So the pod holds nothing and calls nothing, and the policy is as tight
+as this object gets - inbound 8080, outbound DNS.
+
+The ingress direction is not restricted by source in the default, because 8080
+is the port all three probes address. See the rule below.
+
+WHAT THIS OBJECT IS: a ceiling on reachability, not an authentication layer.
+Only the ports declared below are reachable at all - whatever else the process
+binds, now or after the next app update, is blocked without anyone having to
+notice it exists.
+
+WHAT IT IS NOT:
+  - EGRESS IS COARSE. A NetworkPolicy matches CIDRs and selectors and NEVER
+    hostnames, so "only to the database host" cannot be expressed at all. This
+    cluster's CNI is Canal (Flannel plus Calico for policy) and has no FQDN
+    rule; Calico's GlobalNetworkSet could express one but would bind this chart
+    to Calico, the same argument that kept implementation-specific objects out
+    of the Gateway-API sweep (#114). Each egress rule therefore permits its
+    PORT to any destination.
+  - NOT A BOUNDARY WHERE THE CNI DOES NOT ENFORCE ONE. An unenforced policy is
+    accepted by the API server and filters nothing, so everything reads as
+    configured while nothing is filtered.
+  - THE REASONING IS IN TEMPLATE COMMENTS, not in "#" comments: those are part
+    of the rendered object, travel into the cluster and appear in every release
+    diff. ci/run-networkpolicy-test.sh fails on a rendered "#".
+
+THE PORT NUMBERS BELOW ARE POD PORTS, NEVER NODEPORTS. A NetworkPolicy is
+evaluated at the pod's network interface, after kube-proxy has already
+translated a NodePort to the targetPort, so a NodePort number here would match
+nothing while looking strict - and, being the only rule for that port, would
+block every inbound connection instead. ci/run-networkpolicy-test.sh asserts
+every port here against the containerPorts of the pod spec this policy

+       "ResolvedRefs: True" is what a working attachment looks like. An empty
+       status means no controller has looked at the route at all.
+    3. The TLS certificate for the hostname, on the Gateway's listener.
+       ingress.clusterIssuer is NOT used in this mode and is not required: the
+       chart renders no Certificate here, so there is no
+       tls-{{ .Release.Name }}-{{ .Chart.Name }}-ingress secret and nothing for cert-manager to do
+       for this release.
+
+  THE UPLOAD LIMIT IS NOT ENFORCED BY ANYTHING THIS CHART RENDERS.
+
+  In Ingress mode an operator sets nginx.ingress.kubernetes.io/proxy-body-size
+  through ingress.annotations - this installation runs with 25m - because
+  nginx's default of 1m rejects almost every attachment. IN THIS MODE THAT IS
+  GONE: the Gateway API has no body-size field, it is implementation policy
+  rather than routing, and this chart renders no policy object on purpose (it
+  would bind the chart to one Gateway implementation).
+
+  So the limit in force is THE GATEWAY'S, whatever it happens to be, and no
+  value of this chart has any say in it. The failure mode on a webmail client
+  is worth picturing before it happens: a user has written the mail, attached
+  the file and pressed send, and the 413 comes back FROM THE PROXY. It reads
+  like Bulwark being broken, nothing mentions a limit, and the draft is the
+  thing at risk.
+
+  Set the equivalent next to the Gateway, in your implementation's own object,
+  BEFORE you point DNS at it - and size it to what the MAIL SERVER accepts
+  (the Stalwart release above), not to what looks generous here. A webmail
+  client that accepts a 40 MB attachment the mail server will refuse has only
+  moved the failure later.
+
+  ingress.annotations is inert in this mode in general: the Gateway API has no
+  annotation channel for controller behaviour.

+That was true and is no longer - bulwark.httproute.yaml reads it as the route's

+complete without a domain - the calibre-web-automated case, where the gate
+frees both values. The enforcement sits in whichever routing template is
+active; this helper still renders a visible placeholder instead of failing,
+because `helm template` does not render NOTES.txt.
+
+IN GATEWAY MODE THE PUBLIC URL IS THE ROUTE'S HOSTNAME, not ingress.domain, and
+the two differ exactly when httpRoute.hostnames is set explicitly - which is
+how a migration off the Ingress runs. Printing ingress.domain there would hand
+the operator an OIDC redirect URI for the host being migrated AWAY from, and
+that failure surfaces as a rejected login at the identity provider rather than
+as anything about this chart. So the helper follows the active mode.

+HTTPRoute - the Gateway-API alternative to bulwark.ingress.yaml (Gitea #114).
+
+ONE ROUTE, ONE RULE, AT THE ROOT - and the reason is the same one that makes
+the Ingress rule permanently "/": NEXT_PUBLIC_BASE_PATH is compiled into
+Bulwark's bundle, so the application cannot be served under a sub-path at all.
+Which is also why THIS CHART RENDERS NO URLRewrite FILTER and needs none. That
+differs from what #114's measured table and the header of
+ci/run-httproute-match-test.sh both expected of this chart, so it is worth
+writing down where it will be read:
+
+  - This chart has ONE Ingress object, not two (keycloak has two).
+  - This chart has NO rewrite-target annotation and CANNOT have one. Every
+    occurrence of the string "rewrite-target" in this chart - values.yaml, the
+    schema, the Ingress template - is an explanation of why it does not help:
+    the bundle's own asset and API URLs are built for the root, so stripping a
+    prefix at the proxy yields a page that loads and then fetches everything
+    from the wrong place. A `git grep rewrite-target bulwark/` finds those
+    refutations and counts them as occurrences, which is how the expectation
+    arose.
+  - Consequently the #118 prefix/redirect assurance in
+    ci/run-httproute-match-test.sh does not apply here: with no URLRewrite on a
+    prefix other than "/", its precondition is never met. The bare-prefix
+    redirect that freesailarr needs has nothing to redirect here.
+
+WHAT THIS RENDERS, AND WHAT IT MUST NOT
+
+Only an HTTPRoute with parentRefs. No Gateway, no gatewayClassName, no
+Certificate, no implementation-specific policy object - the subset that looks
+identical on nginx-gateway-fabric, Cilium, Envoy Gateway and Istio (decision 1
+of #114). Class and certificate belong to the PLATFORM, on the Gateway and its
+listeners, in cluster-config.
+
+WHAT THIS MODE DROPS FOR THIS CHART, MEASURED ON THE LIVE OBJECT
+
+On 2026-10-12 the live Ingress (jk-cluster, namespace bulwark,
+webmail.bekemeyer-klein.de) carried
+
+    nginx.ingress.kubernetes.io/proxy-body-size: 25m
+
+The CHART does not set it - values.yaml recommends exactly that value and
+explains why the chart cannot pick it (the right number is the mail server's,
+which this chart does not know), so the 25m is the operator's, supplied through
+ingress.annotations. It is therefore invisible to anyone reading this
+repository alone, and it is the single annotation this installation depends on.
+
+In this mode it is gone. The Gateway API has no body-size counterpart: it is
+implementation policy, not routing, and decision 2 of #114 says such a limit is
+DOCUMENTED rather than rebuilt. So the Gateway branch of NOTES.txt names it in
+this chart's own terms - an attachment above the Gateway's default is rejected
+before Bulwark sees a byte, with a 413 from the proxy that reads like an
+application fault, on the one application whose whole purpose is sending files
+to other people.

+NetworkPolicy for bulwark (Gitea #5).
+
+Bulwark is a JMAP webmail CLIENT: it holds no mail, has no database, no cache
+and no broker. Everything it shows lives on a Stalwart server reached over
+bulwark.jmapServerUrl, and that single outbound dependency is what shapes the
+egress rules.
+
+AND IT IS THE ONE CHART WHERE THE EGRESS CAP CAN FAIL QUIETLY. Bulwark's probes
+address its own HTTP port and say nothing about whether the JMAP server is
+reachable - so a release whose JMAP URL sits on a port this policy does not
+allow comes up Ready and then shows an empty, broken webmail. 443 is allowed
+because that is where a published JMAP endpoint lives; a URL pointing straight
+at Stalwart's in-cluster HTTP port (8080) is blocked and needs
+networkPolicy.egress.extraPorts. That asymmetry is in values.yaml and NOTES.txt
+because nothing else will report it.
+
+WHAT THIS OBJECT IS: a ceiling on reachability, not an authentication layer.
+Only the ports declared below are reachable at all - whatever else the process
+binds, now or after the next app update, is blocked without anyone having to
+notice it exists.
+
+WHAT IT IS NOT:
+  - EGRESS IS COARSE. A NetworkPolicy matches CIDRs and selectors and NEVER
+    hostnames, so "only to the database host" cannot be expressed at all. This
+    cluster's CNI is Canal (Flannel plus Calico for policy) and has no FQDN
+    rule; Calico's GlobalNetworkSet could express one but would bind this chart
+    to Calico, the same argument that kept implementation-specific objects out
+    of the Gateway-API sweep (#114). Each egress rule therefore permits its
+    PORT to any destination.
+  - NOT A BOUNDARY WHERE THE CNI DOES NOT ENFORCE ONE. An unenforced policy is
+    accepted by the API server and filters nothing, so everything reads as
+    configured while nothing is filtered.
+  - THE REASONING IS IN TEMPLATE COMMENTS, not in "#" comments: those are part
+    of the rendered object, travel into the cluster and appear in every release
+    diff. ci/run-networkpolicy-test.sh fails on a rendered "#".
+
+THE PORT NUMBERS BELOW ARE POD PORTS, NEVER NODEPORTS. A NetworkPolicy is
+evaluated at the pod's network interface, after kube-proxy has already
+translated a NodePort to the targetPort, so a NodePort number here would match
+nothing while looking strict - and, being the only rule for that port, would
+block every inbound connection instead. ci/run-networkpolicy-test.sh asserts
+every port here against the containerPorts of the pod spec this policy
+selects.

+
+Only an HTTPRoute with parentRefs. No Gateway, no gatewayClassName, no
+Certificate, and no implementation-specific policy object - that subset looks
+identical on nginx-gateway-fabric, Cilium, Envoy Gateway and Istio, which is
+the whole reason the cluster's implementation can be swapped without touching
+this chart. Class and certificate therefore belong to the PLATFORM, on the
+Gateway and its listeners.
+
+ingress.clusterIssuer is meaningless here - this chart renders no Certificate
+in this mode - and it is not demanded either: its only required() sits inside
+calibre-web-automated.ingress.yaml, behind ingress.enabled.
+
+THE UPLOAD LIMIT IS THE ONE THING THIS MODE LOSES, AND IT IS NOT REBUILT
+
+cwa.maxUploadFileSize is rendered into nginx.ingress.kubernetes.io/proxy-body-size
+and nginx.org/client-max-body-size by the Ingress template. The Gateway API has
+NO counterpart: it knows no body size at all, because a request-body limit is
+implementation-specific policy and lives in an implementation's own object
+(ClientSettingsPolicy on nginx-gateway-fabric, ClientTrafficPolicy on Istio,
+and so on). Rendering one here would bind this chart to one implementation and
+to a CRD whose presence it cannot check, so the limit is DOCUMENTED instead -
+NOTES.txt says in this mode that the value is not enforced and names where to
+set it. The price is named and deliberate: whoever overlooks that output gets
+the Gateway's default limit, and an oversized book fails as a proxy error
+rather than as a message from CWA. This chart is an e-book library, so the
+value is not decoration - a book above the Gateway's default is rejected, and
+the rejection carries no hint that a chart value was ignored.
+
+ingress.domain, AND WHY THIS FILE CHANGES WHAT CAN BE CLAIMED ABOUT IT
+
+Checked for this chart rather than copied: ingress.domain is read in the
+Ingress template and - until this file existed - NOWHERE else. No environment
+variable, no probe Host header, no URL the app builds itself; CWA is told its
+address by nothing. That is why values.yaml could say that switching the
+Ingress off makes domain unnecessary along with clusterIssuer.
+
+This file is now a second reader (when httpRoute.hostnames is empty), so that
+sentence holds only while BOTH modes are off. It is corrected in values.yaml
+and in values.schema.json rather than left standing. In Gateway mode with

+{{- /*
+NetworkPolicy for calibre-web-automated (Gitea #5).
+
+Calibre-Web-Automated keeps its library on a PVC and has no database and no
+cache of its own, so the only outbound traffic that matters is metadata
+lookups: cover art and book details fetched from public providers over HTTPS.
+
+That is why 443 is allowed and nothing else is. The failure mode if it were
+not: metadata lookups return nothing, which looks like a provider being down
+rather than like a policy - so the rule is here rather than left to
+extraPorts.
+
+WHAT THIS OBJECT IS: a ceiling on reachability, not an authentication layer.
+Only the ports declared below are reachable at all - whatever else the process
+binds, now or after the next app update, is blocked without anyone having to
+notice it exists.
+
+WHAT IT IS NOT:
+  - EGRESS IS COARSE. A NetworkPolicy matches CIDRs and selectors and NEVER
+    hostnames, so "only to the database host" cannot be expressed at all. This
+    cluster's CNI is Canal (Flannel plus Calico for policy) and has no FQDN
+    rule; Calico's GlobalNetworkSet could express one but would bind this chart
+    to Calico, the same argument that kept implementation-specific objects out
+    of the Gateway-API sweep (#114). Each egress rule therefore permits its
+    PORT to any destination.
+  - NOT A BOUNDARY WHERE THE CNI DOES NOT ENFORCE ONE. An unenforced policy is
+    accepted by the API server and filters nothing, so everything reads as
+    configured while nothing is filtered.
+  - THE REASONING IS IN TEMPLATE COMMENTS, not in "#" comments: those are part
+    of the rendered object, travel into the cluster and appear in every release
+    diff. ci/run-networkpolicy-test.sh fails on a rendered "#".
+
+THE PORT NUMBERS BELOW ARE POD PORTS, NEVER NODEPORTS. A NetworkPolicy is
+evaluated at the pod's network interface, after kube-proxy has already
+translated a NodePort to the targetPort, so a NodePort number here would match
+nothing while looking strict - and, being the only rule for that port, would
+block every inbound connection instead. ci/run-networkpolicy-test.sh asserts
+every port here against the containerPorts of the pod spec this policy
+selects.

+#
+# Usage: ci/gateway-api-crds.sh        (called by ci/run-install-test.sh)
+#
+# WHY NOT A STUB CRD, WHICH IS WHAT ci/common/ DOES FOR OnePasswordItem
+#
+# Because a stub would make the install-test prove nothing. ci/common's
+# OnePasswordItem CRD is schema-less on purpose (x-kubernetes-preserve-unknown-
+# fields): nobody is testing the 1Password operator's API, only that the chart's
+# CR applies. For an HTTPRoute the situation is the opposite - the SCHEMA is the
+# entire value of the exercise. With a schema-less stub the API server accepts a
+# malformed parentRefs, a backendRef with a port written as a string, a
+# path type that does not exist; the install goes green and the only thing
+# demonstrated is "something was created". With the real CRDs the same apply is
+# validated field by field, and a malformed route fails the install-test loudly.
+#
+# This is the half that CANNOT be moved into a render test: a render cannot know
+# the Gateway API's schema. And the half the CRDs cannot cover is held by
+# ci/run-httproute-match-test.sh - schema validation accepts an empty
+# parentRefs list and a backendRef naming a Service that does not exist.
+#
+# What neither proves, and nothing here can: that traffic flows. No Gateway
+# controller runs in k3d, so no route is ever reconciled and no status is ever
+# written. Provable: the object is schema-valid and the pod becomes Ready.
+#
+# WHY --server-side, AND THE MEASUREMENT BEHIND IT
+#
+# Client-side `kubectl apply` stores the whole applied object in the
+# kubectl.kubernetes.io/last-applied-configuration annotation, and an object's
+# annotations may total at most 262144 bytes. The HTTPRoute CRD of the standard
+# channel is 429367 bytes of YAML, which comes to 244792 bytes as JSON
+# (measured on v1.6.3, re-read through ci/yaml2json) - i.e. 93% of the limit,
+# with every release adding fields. So client-side apply happens to fit today
+# and is one upstream release away from failing with "metadata.annotations: Too
+# long", on a Renovate PR that has nothing to do with it. Server-side apply
+# writes no such annotation and has no such limit.
+#
+# This is also why the CRDs are NOT in ci/common/, which ci/run-install-test.sh
+# applies client-side for EVERY chart: putting them there would hand that
+# landmine to all 20-odd charts and spend the download on charts that render no
+# route at all.
+#
+# WHY DOWNLOADED AND NOT VENDORED
+#
+# 1.1 MB of generated YAML in the repository would go stale invisibly and would
+# bury every diff that touches ci/. Downloading a PINNED artifact is what this
+# repo already does for every other piece of CI tooling - Trivy's tarball, k3d's
+# install script, kubectl - each with a `# renovate:` comment keeping the pin

+# An overlay and not a change to ci/keycloak/test-values.yaml: the install-test
+# runs exactly ONE configuration per chart, and this chart's fixture is the
+# expensive and informative one - two replicas against a throwaway PostgreSQL,
+# two init containers, `kc.sh build` under readOnlyRootFilesystem, and the
+# Infinispan cluster forming over jdbc-ping (see that file for the four things
+# only a real install can prove). Trading all of it for a CRD schema check that
+# cyberchef's fixture already performs against the real Gateway-API CRDs would
+# be a bad swap. The install keeps the two Ingresses; the two routes are held
+# here, at render level, which is where their silent failure modes live.
+#
+# ingress.enabled: false is not optional here. The two modes are mutually
+# exclusive and the chart aborts its own render when both are true, so an
+# overlay that only switched httpRoute on would turn this test red.
+#
+# WHAT THIS OVERLAY COVERS, WHICH IS BOTH ROUTING OBJECTS:
+#
+#   - ingress.domain comes from the fixture (keycloak.ci.example.com), so the
+#     PUBLIC route renders with its hostname from that single source of truth
+#     (httpRoute.hostnames stays empty on purpose - the fallback is the path
+#     that every installation will actually use).
+#   - ingress.admin.enabled is true in the fixture with
+#     ingress.admin.domain set, so the ADMIN route renders too, and its
+#     parentRefs fall back to httpRoute.parentRefs below - the empty-admin
+#     branch, which is the one an installation hits unless it wants an
+#     internal Gateway.
+#   - every route's backendRef is checked against the serving Service of the
+#     same render. They all point at the SAME Service, by PORT NUMBER
+#     (keycloak.ports.http) rather than by the name "http" the Ingress uses,
+#     because backendRefs takes a PortNumber - so this overlay is what holds
+#     that number against the Service's.
+#   - THE TWO REALM ROUTES (Gitea #122), which come from keycloak.realmHosts in
+#     the fixture rather than from this file. Nothing is repeated here on
+#     purpose: the fixture installs them as Ingress objects and this overlay
+#     turns the same two entries into HTTPRoutes, so one definition covers both
+#     modes and the two halves cannot drift into describing different hostnames.
+#     What the routes add to the two above is a SECOND RULE SHAPE - an Exact
+#     match on / carrying a RequestRedirect filter and no backendRefs at all.
+#     That rule is reported as "not checked" by this test, correctly and by
+#     design: a filter-only rule has no backend to resolve. The assertion it
+#     does earn is on its sibling rule, the PathPrefix one that points at the
+#     Service. The prefix/redirect pairing check of #118 does NOT fire for these
+#     routes and must not: it is scoped to rules that STRIP a prefix with a
+#     ReplacePrefixMatch rewrite, and these strip nothing - they redirect the
+#     bare root of a hostname that serves one realm.
+#     The entries also cover the two Ingress-mode forms (one with a
+#     clusterIssuer, one without) and what this test holds about them is their
+#     INERTNESS: neither tlsSecretName nor clusterIssuer nor the per-entry
+#     annotation may appear anywhere in a rendered route.

+#
+# A note on this chart's install-test, because it has a history. It had failed
+# on the Gitea runner since the move - php-fpm unable to read /app/index.php,
+# the startup probe 403ing through its whole budget, the pod never Ready (Gitea
+# #51), reproduced on two images while the same chart and image ran healthy in
+# the cluster. The chart was deliberately kept OUT of ci/excluded-charts.txt so
+# that a pass would be noticed rather than silenced, and in the PR that added
+# this overlay it PASSED: pod 1/1 Ready in 22s, 0 restarts, no permission error
+# in the job. Since that PR's rendered defaults are byte-identical to
+# origin/main, the chart is ruled out as the cause and the runner is the
+# implicated layer - which is where #51 had already placed it. It reproduced
+# on every run of that branch since, so it is not a fluke, and #51 was closed
+# on that round. What was NEVER identified is the cause: nobody established
+# what changed on the runner, and the diagnostic programme in that issue
+# (docker info for userns and the dind configuration, the same image in a
+# local k3d without remapping) was not executed. So if this chart's
+# install-test goes red again, that is a fresh finding and not a known quirk -
+# and this comment is the context it should be read against.
+#
+# Either way this overlay stays load-bearing: the install-test installs the
+# INGRESS mode (that is what the fixture sets), so the Gateway mode of this
+# chart is covered here at render level and nowhere else - the same situation
+# as every other chart in the sweep.
+#
+# ingress.enabled: false is not optional here - the chart ships it as TRUE and
+# aborts its own render when both modes are on.
+#
+# httpRoute.hostnames MUST be supplied, and this overlay is the second in the
+# repository that has to (homeassistant's was the first). The other charts let
+# an empty hostnames list fall back to ingress.domain; this chart has no
+# ingress.domain, and it deliberately does not reuse ingress.hosts from the
+# fixture, because those entries carry tlsSecretName values that address
+# nothing once the certificate sits on the Gateway's listener. The render
+# aborts on an empty list rather than publishing a route that matches every
+# request reaching its listener.
+#
+# THREE hostnames on ONE object, which is the shape this chart's production
+# installation has (three hosts, all serving the same Service at "/"). It is
+# also the shape the test should see: one HTTPRoute, one rule, one backendRef,

+#     empty on purpose: the fallback is the path every installation will
+#     actually use.
+#   - ingress.nodeGroup comes from the fixture too, so the route is checked to
+#     point at THAT GROUP'S http Service and no other. This chart is the one in
+#     group 3 where the backend is group-scoped, and the ONE-route-not-one-
+#     per-group property is exactly what would be easy to get wrong on a copy.
+#   - the backendRef is checked against the per-group http Service of the same
+#     render, by PORT NUMBER (ports.http.containerPort) rather than by the name
+#     "http" the Ingress uses, because backendRefs takes a PortNumber. Note
+#     that this chart's NodePort Services publish a DIFFERENT number
+#     (ports.<name>.nodePort) than the container binds, so naming the wrong one
+#     here would be a plausible mistake - this overlay is what catches it.
+#
+# No URLRewrite filter is rendered by this chart in either mode, so the #118
+# prefix/redirect assurance has no precondition to meet here.
+#
+# NOT covered here, and none of it can be:
+#
+#   - that the hostname answers. No Gateway controller runs in CI and no route
+#     reaches "Accepted: True".
+#   - THE CORS CONFIGURATION, which is the thing this chart actually loses in
+#     this mode and the one that breaks the bulwark webmail. It lives in the
+#     operator's ingress.annotations, the chart has no values for it, and the
+#     Gateway API's own CORS filter is Extended-support with observed
+#     implementation variance - all of which is documented in values.yaml and
+#     printed by NOTES.txt. Documentation is not something a test can assert.
+#   - that SMTP/IMAP still work. They never went through the Ingress and do not
+#     go through the route; the mail Certificate that serves them keeps being
+#     rendered in this mode, which is this chart's distinguishing feature in
+#     the sweep, and no render test looks at whether it was left alone.
+#   - THE MTA-STS ROUTE (Gitea #123), which is the second HTTPRoute this chart
+#     renders. Its backendRef is held against the same per-group http Service
+#     by the same port number, so the one place information travels from the
+#     Service object into a route template is checked twice rather than once.
+#     What the list below is shaped for is the three cases the entry form has:
+#     an entry WITH a clusterIssuer, an entry WITHOUT one, and a host on a
+#     SUBDOMAIN - the last because mta-sts.sub.<domain> is one label deeper
+#     than *.<domain> and a parent wildcard does not cover it.
+#
+#     Both TLS fields are INERT IN THIS MODE: TLS sits on the Gateway's
+#     listener and this chart renders no certificate for an HTTP hostname
+#     here. They are set anyway, and that is the assertion - the render has to
+#     ACCEPT them in Gateway mode without requiring them, because the mirror
+#     image (tlsSecretName required in Ingress mode) is what makes them
+#     mode-specific rather than optional-everywhere.
+#
+#     The Ingress half of this feature is NOT exercised here - this overlay's

+#
+# THE UPDATE TYPE COMES FROM RENOVATE, AND THAT IS THE POINT (Gitea #128).
+# Renovate has already classified the jump; passing `{{{updateType}}}` in is
+# what makes a chart minor possible at all. Deriving it here from appVersion
+# would be blind to exactly the case that prompted the rule: `freesailarr`
+# carries a hand-maintained `appVersion: "1.0.0"` for ten upstreams and it never
+# moves, so prowlarr's 2.5.2 -> 2.6.5 — an image tag in values.yaml — is a
+# minor with an unchanged appVersion. README, "Dependency updates (Renovate)".
+#
+# WHAT A CHART MINOR BUYS, AND WHAT IT DOES NOT. It makes the number honest: an
+# app minor stops arriving as a chart patch. It does NOT oblige anyone to read
+# the release notes — that variant was decided against — so an app minor that
+# changes a default can still reach `main` unremarked. What the number does is
+# make the jump VISIBLE to everything downstream that sees only our chart
+# version (Fleet's `fleet.yaml` in `cluster-config` among them), where a patch
+# is invisible. See the wiki, Lessons-Learned.
+#
+# THE SECOND ARGUMENT IS OPTIONAL ON PURPOSE. `postUpgradeTasks` only runs when
+# the command is allow-listed in the *instance* config, which is not visible
+# from this repository, and a command that does not match the allow-list is
+# skipped SILENTLY. So a missing update type — a narrower allow-list pattern, an
+# older Renovate, a template field that is not populated — must not be a
+# failure: without it the script falls back to what it did before #128 and every
+# chart PR still gets its version bump.
 #
 # Everything is derived from the base commit (HEAD, which during
 # postUpgradeTasks still points at the base branch), never from the working
 # tree's `version:`. That makes repeated runs on the same branch idempotent —
 # Renovate calls the script once per dependency update, and a branch may carry

+# Bump-level test: every case of ci/renovate-bump-chart.sh, held against the
+# version string it writes into a throwaway chart.
+#
+# Usage: ci/run-bump-level-test.sh
+#
+# WHY THIS TEST EXISTS (Gitea #128)
+#
+# Until #128 the hook was a calculator with one branch: app major -> chart
+# major, everything else -> chart patch. With the update type coming from
+# Renovate it became DECIDING LOGIC — it is now the thing that says how big a
+# change the cluster is being offered, and the chart version is the only signal
+# anything downstream sees (README, "Chart dependencies": Fleet's `fleet.yaml`
+# in `cluster-config` sees our chart version and nothing inside the package).
+#
+# And its failure mode is silence. A wrong level is a valid version string: the
+# PR goes green, the chart publishes, and the only symptom is a number that
+# understates what it ships. Nothing in the pipeline reads it, so nothing but a
+# test can.
+#
+# HOW A CASE IS BUILT, AND WHY A REAL GIT REPO
+#
+# The script reads the BASE commit (`git show HEAD:<chart>/Chart.yaml`) and the
+# working tree, so a case is not a function call — it is a repository with a
+# commit and a dirty file. Each case therefore gets a throwaway `git init` in a
+# unique temp directory, one commit carrying the base Chart.yaml, and the new
+# Chart.yaml written over it uncommitted. That is exactly the state Renovate's
+# `postUpgradeTasks` hook runs in.
+#
+# Signing is switched off per command (`-c commit.gpgsign=false`): this
+# workspace signs every commit through an SSH signer, and a throwaway repo has
+# no business invoking it. The temp root comes from `mktemp -d`, because /tmp is
+# shared with whatever else runs on this machine.
+#
+# The runners have no pyyaml, no yq and no Docker — the same constraint
+# ci/run-selector-match-test.sh and ci/run-quantity-render-test.sh work under.
+# None is needed: the fixtures are six-line Chart.yaml files written by printf,
+# and the assertion is one `version:` line read back with sed. Helm is not
+# needed either, which is why this job carries no Helm step.
+#
+# WHAT IS ASSERTED, AND WHAT IS NOT
+#
+# Asserted: the full `version:` line (so the `+up` suffix and its dash-to-dot
+# normalization are covered by every case), the exit code, and for the cases
+# that must leave the chart alone, that the line is untouched.
+#
+# NOT asserted, and not assertable from here: that Renovate passes the update
+# type at all. The hook only runs when the command is allow-listed in the
+# *instance* config, which lives outside this repository — and a pattern that
+# does not match is skipped silently. That is why a missing second argument is
+# itself a case here (it must fall back, not fail), and why the PR that
+# introduced this carries a dry-run instead of a claim.

+# HTTPRoute render test: every HTTPRoute a chart renders is held against the
+# Services of the SAME render, and against the one condition without which the
+# route attaches to nothing.
+#
+# Usage: ci/run-httproute-match-test.sh [chart ...]   (no argument = all charts)
+#
+# WHAT IT GUARDS AGAINST, AND WHY NEITHER A RENDER NOR AN INSTALL DOES (#114)
+#
+# An HTTPRoute is the Gateway-API alternative to the Ingress (README, "Ingress
+# and Gateway API"), and it has two silent failure modes that look exactly like
+# a working route from the outside:
+#
+#   parentRefs EMPTY - a route without a parent attaches to no Gateway. The
+#     object is created, it is schema-valid, no controller rejects it, and it
+#     routes nothing. There is no event and no condition; the only symptom is a
+#     hostname that does not answer. The charts abort the render over this, and
+#     this test is the half that catches a chart which forgot to.
+#   backendRefs pointing at NOTHING - the reference is by name, in the release
+#     namespace, and nothing validates that the name exists. A typo, a renamed
+#     Service, or a port number that no longer matches the Service's port
+#     yields a route that resolves to no endpoint. ResolvedRefs goes False in
+#     the route's STATUS, which only exists once a controller has looked at it
+#     - so in CI, where no Gateway controller runs, nothing reports it at all.
+#   A PREFIX STRIPPED WITHOUT THE BARE PREFIX REDIRECTED (#118) - the third
+#     finding, and the one that is not about an object pointing nowhere but
+#     about an object pointing somewhere WRONG. A rule that matches
+#     PathPrefix "<path>" (anything but "/") and carries a URLRewrite filter
+#     with ReplacePrefixMatch strips the prefix before the app sees the
+#     request. For the slashed form that is correct. For the BARE form -
+#     "<path>", no trailing slash - the request becomes "/" and the app
+#     answers 200, while the browser's document URL keeps the prefixless form:
+#     every relative link in that page then resolves against the PARENT of
+#     that path, which is the host root. On a shared host the root belongs to
+#     a different application, so the app's own assets and XHRs are answered
+#     by its neighbour. Nothing in the chart, the render, the schema or the
+#     install reports any of it; the symptom is a half-working UI and a
+#     neighbour in the access log, which points nowhere useful.
+#
+#     So: wherever a route strips a prefix, the SAME route must also carry a
+#     rule matching that path with type Exact and a RequestRedirect filter.
+#     Per HTTPRoute object, because Gateway-API matching precedence is a
+#     property of one route - a different route is a different hostname and
+#     says nothing about this one. Exact outranks every prefix match in that
+#     precedence, so the pairing is about existence and not about order.
+#     freesailarr is the FIRST AND, AS OF GROUP 3 OF #114, THE ONLY chart this
+#     applies to. The line that used to stand here said bulwark was the second
+#     rewrite-target chart and would meet the same check when group 3 landed.
+#     Group 3 landed and it does not: bulwark has ONE Ingress object, no
+#     rewrite-target annotation, and cannot have one - NEXT_PUBLIC_BASE_PATH is
+#     compiled into its bundle, so it cannot be served under a sub-path at all
+#     and its route is one rule at "/" with no URLRewrite filter. Every
+#     occurrence of the string "rewrite-target" in that chart is an explanation
+#     of why it does not help, and #114's measured table arrived at "bulwark,
+#     freesailarr" by grepping for the string rather than for the annotation.
+#     The check stays over all charts for the reason below - the mistake
+#     arrives by copy - not because a second chart is known to need it.
+#
+# And the install-test cannot close either gap, even with the real CRDs in the
+# cluster: schema validation accepts an empty parentRefs list and accepts a
+# backendRef to a Service that does not exist. The CRDs prove the object is
+# WELL-FORMED; this test is what proves it POINTS SOMEWHERE.
+#
+# Over ALL charts and not the changed ones, for the same reason as
+# ci/run-quantity-render-test.sh and ci/run-selector-match-test.sh: the mistake
+# arrives by copy into a chart whose own diff nobody reads for it - and this
+# convention is going to be copied 20 more times when the sweep of #114 runs.
+# Running over everything also means there is no list to maintain: adding a
+# chart enrols it.
+#
+# HOW THE YAML IS PARSED
+#
+# By Helm, through ci/yaml2json, exactly as ci/run-selector-match-test.sh does
+# it - the runners have neither pyyaml nor yq, and a parser written in awk
+# would be able to read nothing, find no route and report no finding, leaving
+# this test green for a chart it never looked at. The only textual step is the
+# document split on a line that is exactly "---" in column one, and getting
+# that wrong is not a false pass: the fragment stops being valid YAML and helm
+# exits 1. See that script's header for the long form.
+#
+# WHAT IS DELIBERATELY NOT CHECKED, so the gaps are not mistaken for coverage
+#
+#   - THAT TRAFFIC FLOWS. No Gateway controller runs in CI and none will; a
+#     route's status is written by the implementation, so "Accepted: True" is
+#     not obtainable here. What is obtainable: the object is schema-valid
+#     (install-test, against the real CRDs) and it names a Service and a port
+#     that exist (this test). Routing itself is unproven, by construction.
+#   - MUTUAL EXCLUSION with the Ingress. Every chart aborts its own render when
+#     ingress.enabled and httpRoute.enabled are both true, which is where that
+#     check belongs: this test renders ONE configuration per chart, and a
+#     render-level rule here would have to assume the switch is chart-global.
+#     That holds for the pilot and may not hold for the multi-app charts of the
+#     sweep (matrix-synapse renders in a loop, keycloak and bulwark have two
+#     Ingresses each), so the rule is not written down here where it would have
+#     to be undone.
+#   - CROSS-NAMESPACE backendRefs and non-Service backends. A backendRef into
+#     another namespace needs a ReferenceGrant on the other side and its target
+#     is by definition not in this render; a backend that is not a Service is
+#     some implementation's own kind. Both are REPORTED as "not checked" and
+#     are never counted as passing, because a green tick for a code path nobody
+#     entered is worse than an honest gap (README, "Two rules for every check
+#     added here").
+#   - A RULE WITHOUT backendRefs. Legal - a rule carrying only a
+#     RequestRedirect filter needs no backend - so it is reported, not failed.
+#     The redirect rule the prefix check below demands is exactly such a rule,
+#     so a chart that satisfies that check also earns one "not checked" line
+#     here. Both are correct: the pairing is an assertion, the missing backend
+#     is an honest gap.
+#   - THAT ANY REDIRECT IS EVER SERVED. The prefix/redirect pairing proves the
+#     rendered OBJECT carries a RequestRedirect rule on the bare prefix. It
+#     does not prove that a 301 ever reaches a client, and it cannot: no
+#     Gateway controller runs in CI, nothing evaluates matching precedence,
+#     and no route reaches "Accepted: True" - so whether the implementation
+#     honours the statusCode, or declines it and fails the whole route, is
+#     outside what this test can see. What is proven is that the rule exists,
+#     that it matches the right path, and that the chart did not silently stop
+#     rendering it.
+#
+# AND THE ANTI-VACUUM GUARDS, because this test can be green over nothing. The
+# convention ships with httpRoute.enabled: false, so a chart renders no route
+# at all unless its CI values or an overlay switch the mode on. Two rules:
+#
+#   1. ci/httproute/<chart>.yaml is an overlay applied last, whose only job is
+#      to put a chart into Gateway mode for this test. A chart that HAS one and
+#      still renders no HTTPRoute FAILS - the overlay exists for exactly that.
+#   2. If no HTTPRoute at all was checked across the whole run, the run fails.

+# Selector-match render test: every label selector a chart renders is held
+# against the labels of the pod templates in the SAME render.
+#
+# Usage: ci/run-selector-match-test.sh [chart ...]   (no argument = all charts)
+#
+# WHAT IT GUARDS AGAINST, AND WHY A GREEN ROLLOUT DOES NOT (Gitea #96)
+#
+# Two kinds of object in this repository select pods by label, and BOTH of them
+# fail silently when the selector matches nothing:
+#
+#   topologySpreadConstraints - a constraint whose labelSelector matches no pod
+#     is TRIVIALLY SATISFIED. It is a condition over zero pods, so every
+#     placement meets it: nothing is distributed, the rollout is green, no event
+#     is emitted and no log line appears. With whenUnsatisfiable: DoNotSchedule
+#     this is worse rather than better, because the object then reads like a
+#     guarantee that two replicas sit on different nodes.
+#   PodDisruptionBudget - a budget whose selector matches no pod does its
+#     arithmetic over zero pods and never blocks an eviction. `kubectl drain`
+#     takes the whole group at once while the object sits in the namespace
+#     looking like protection.
+#
+# Neither is a render error, neither is an install-test failure, and neither is
+# visible in a diff: the chart that breaks it is usually a chart that RENAMED a
+# label somewhere else. Charts keep their selector and their pod labels in one
+# helper for that reason (stalwart.groupLabels, keycloak's app label) - but one
+# definition only helps while nobody writes a second one, and that is the part a
+# test can hold.
+#
+# Over ALL charts and not the changed ones, for the same reason as
+# ci/run-quantity-render-test.sh: the mistake arrives by copy into a new chart,
+# whose own diff nobody reads for it, and running over everything means there is
+# no list to maintain - adding a chart enrols it.
+#
+# HOW THE YAML IS PARSED, AND WHY NOT WITH A PARSER WRITTEN HERE
+#
+# The runners have neither pyyaml nor yq - measured, the same constraint
+# ci/run-trivy-config.sh and ci/run-quantity-render-test.sh work under. Writing
+# a YAML reader in awk or sed was the obvious alternative and is the wrong one:
+# its failure mode is a parser that quietly reads nothing, finds no selector,
+# reports no mismatch, and leaves this test green for a chart it never looked
+# at - the exact class of signal this repository removes rather than adds.
+#
+# So HELM is the parser, which is a YAML implementation that is already
+# installed, already trusted, and already the one that produced the manifests.
+# ci/yaml2json is a one-template chart that prints its values back as JSON; the
+# rendered manifest stream is handed to it as a VALUES FILE and comes back as
+# JSON that python3 reads with its standard library. What IS done textually is
+# only the document split, on a line that is exactly "---" in column one, and
+# the consequence of getting that wrong is not a false pass: the fragment stops
+# being valid YAML and helm exits 1.
+#
+# WHAT IS DELIBERATELY NOT CHECKED
+#
+#   - preferred podAffinity and podAntiAffinity of either strength. They carry
+#     labelSelectors too, but their semantics are "relative to pods that exist",
+#     and a term matching nothing is a legitimate configuration rather than a
+#     mistake: a preference that cannot be met is dropped and an anti-affinity
+#     over zero pods is satisfied. Out of scope, and named so that the gap is
+#     not mistaken for coverage.
+#
+#     requiredDuringSchedulingIgnoredDuringExecution podAffinity is NOT in that
+#     gap and is checked (Gitea #101). Its failure is not a preference quietly
+#     dropped: a required term whose selector matches no pod in the release can
+#     never be satisfied, so the pod stays Pending forever. For the workload
+#     that introduced one here - paperless-ngx' consume CronJob, pinned onto the
+#     node of its StatefulSet pod so that Longhorn will mount the shared RWX
+#     volume - that would mean a mover that silently stops moving, with one
+#     Pending pod per schedule and a green render behind it. The term names a
+#     label written in ANOTHER template, which is the copy this test holds.
+#   - selectors expressed ONLY through matchExpressions. Evaluating a set-based
+#     requirement means reimplementing label-selector semantics, which is a
+#     second parser by another name. Those are REPORTED as "not checked" and
+#     are never counted as passing, because a green tick for a code path nobody
+#     entered is worse than an honest gap (README, "Two rules for every check
+#     added here").
+#
+# AND THE ANTI-VACUUM GUARDS, because this test can be green over nothing. A
+# chart renders a PDB or a spread constraint only above a replica threshold, and
+# every chart's CI fixtures sit below it. Two rules therefore apply:
+#
+#   1. ci/selector-match/<chart>.yaml is an overlay applied last, whose only job
+#      is to push a chart over that threshold. A chart that HAS one and still
+#      renders no selector FAILS - the overlay exists for exactly that, so an
+#      overlay that stopped working is a finding and not a shrug.
+#   2. If no selector at all was checked across the whole run, the run fails.

+# YAML-scalar render test: an operator value that must arrive in the manifest as
+# a STRING is held against the manifest it actually produced.
+#
+# Usage: ci/run-yaml-scalar-render-test.sh [chart ...]   (no argument = all charts)
+#
+# WHAT IT GUARDS AGAINST (Gitea #11, and #112 turned out to be the same genus)
+#
+# A value is rendered into a YAML scalar without `| quote`. The operator quotes
+# it correctly in their values file, Helm passes the string's CONTENT through,
+# and the quotes are gone again in the manifest. Two outcomes, and the quiet one
+# is the worse one:
+#
+#   1. LOUD, but misdirected - the content is not a legal plain scalar and the
+#      render aborts. Measured on paperless-ngx' consume CronJob, whose schedule
+#      was unquoted: a schedule in the commonest cron notation of all (a star, a
+#      slash, an interval) made `helm template` exit 1 with
+#
+#        error converting YAML to JSON: yaml: line 6: did not find expected
+#        alphabetic or numeric character
+#
+#      YAML read the leading "*" as an alias indicator. The message names the
+#      TEMPLATE and the operator's own value is nowhere in it, so the search
+#      starts in the wrong place. "@daily" fails the same way.
+#   2. SILENT until the API server - the content IS a legal plain scalar, just
+#      not a string. "true" becomes a bool, "0755" becomes an integer, and the
+#      chart renders perfectly. Kubernetes then rejects the object with
+#      "cannot unmarshal number into Go struct field EnvVar.value of type
+#      string" - at apply time, which for this repository means in the
+#      install-test or in a cluster, never in the render.
+#
+# Neither is caught by "does helm template exit 0" alone: the first one is, but
+# only if something actually renders the object, and the second one is not
+# caught at all.
+#
+# WHAT IS ASSERTED, and all three are properties Kubernetes itself requires -
+# there is no chart for which the opposite is a legitimate configuration, which
+# is why this needs no per-chart expectations:
+#
+#   1. CronJob .spec.schedule is a non-empty string.
+#   2. Every env[].value of every container and initContainer is a string.
+#   3. Every metadata.labels and metadata.annotations value is a string
+#      (the API types both as map[string]string).
+#
+# WHY OVER ALL CHARTS, not the changed ones: the same reason as
+# ci/run-quantity-render-test.sh and ci/run-selector-match-test.sh. The env
+# block is copied into every chart rather than shared, so the unquoted form
+# travels by copy into whatever chart is started from an older one - and that
+# chart's own pull request is not where anyone would look for it. Running over
+# everything also means there is no list to maintain: adding a chart enrols it.
+#
+# THE OVERLAYS, AND WHY THIS TEST IS USELESS WITHOUT THEM
+#
+# The defect above survived in a shipped chart for months for one reason: the
+# object that carried it is rendered by NO fixture. paperless-ngx' CronJob sits
+# behind smbConnection.enabled, which is false in the chart defaults and in
+# every committed fixture, so neither lint, nor the render tests, nor the
+# install-test ever produced it. A test that renders only what the fixtures
+# already render would have been just as blind.
+#
+# So ci/yaml-scalar/<chart>.yaml is an overlay applied LAST whose job is to
+# switch such objects on AND to feed them the hostile values - a schedule
+# beginning with a star, an env value that is a bare "true". Two rules follow,
+# the same ones ci/run-selector-match-test.sh works under:
+#
+#   1. A chart that HAS an overlay and still renders none of the three things
+#      above FAILS. The overlay exists for exactly that, so an overlay that
+#      stopped reaching its object is a finding and not a shrug.
+#   2. If nothing at all was asserted across the whole run, the run fails. A
+#      pass over zero assertions is not a pass.
+#
+# WHAT IS DELIBERATELY NOT CHECKED, so the gap is not mistaken for coverage:
+#
+#   - Values rendered into a scalar that is hand-quoted in the template
+#     ("{{ .Values.x }}"). Those are strings in the output, so this test is
+#     blind to them by construction; what they can still do is break the YAML
+#     when the value itself contains a quote or a backslash, and only `| quote`
+#     fixes that. Reported here rather than silently implied.
+#   - Everything that is not a label, an annotation, an env value or a schedule.
+#     A bare `storage:` or `className:` is just as unquoted, but its value space
+#     is DNS labels and quantities, where no legal value is YAML-ambiguous. The
+#     three above are where operator free text actually lands.
+#   - Whether a cron schedule is a VALID schedule. That is the cron
+#     controller's judgement, and narrowing the schema to a regex was considered
+#     and rejected: the defect was never a wrong schedule, it was a correct one
+#     rendered bare.
+#
+# How the YAML is parsed: with helm, via ci/yaml2json, exactly as in
+# ci/run-selector-match-test.sh - the runners have neither pyyaml nor yq, and a
+# YAML reader written in awk here would fail by quietly reading nothing and
+# staying green. That script's header carries the full argument.

+NetworkPolicy for cyberchef (Gitea #5).
+
+CyberChef is a static web app: nginx serves files, the recipes run in the
+visitor's browser, and the pod holds no state and talks to nothing. That makes
+this the simplest policy in the repository and a good one to read first.
+
+What it is worth here is almost entirely the two CEILINGS rather than any
+source restriction: only 8080 is reachable, and outbound traffic is capped at
+DNS. The pod has no reason to open a single outbound connection - it serves
+static files - so the egress cap is as tight as the object allows. Were this
+image ever to gain a second listener, or were the container ever compromised,
+neither could be reached or could reach out.
+
+The ingress direction is NOT restricted by source in the default, and that is
+not an oversight: 8080 is the port all three probes address. See the probe note
+on the rule below.
+
+WHAT THIS OBJECT IS: a ceiling on reachability, not an authentication layer.
+Only the ports declared below are reachable at all - whatever else the process
+binds, now or after the next app update, is blocked without anyone having to
+notice it exists.
+
+WHAT IT IS NOT:
+  - EGRESS IS COARSE. A NetworkPolicy matches CIDRs and selectors and NEVER
+    hostnames, so "only to the database host" cannot be expressed at all. This
+    cluster's CNI is Canal (Flannel plus Calico for policy) and has no FQDN
+    rule; Calico's GlobalNetworkSet could express one but would bind this chart
+    to Calico, the same argument that kept implementation-specific objects out
+    of the Gateway-API sweep (#114). Each egress rule therefore permits its
+    PORT to any destination.
+  - NOT A BOUNDARY WHERE THE CNI DOES NOT ENFORCE ONE. An unenforced policy is
+    accepted by the API server and filters nothing, so everything reads as
+    configured while nothing is filtered.
+  - THE REASONING IS IN TEMPLATE COMMENTS, not in "#" comments: those are part
+    of the rendered object, travel into the cluster and appear in every release
+    diff. ci/run-networkpolicy-test.sh fails on a rendered "#".
+
+THE PORT NUMBERS BELOW ARE POD PORTS, NEVER NODEPORTS. A NetworkPolicy is
+evaluated at the pod's network interface, after kube-proxy has already
+translated a NodePort to the targetPort, so a NodePort number here would match
+nothing while looking strict - and, being the only rule for that port, would
+block every inbound connection instead. ci/run-networkpolicy-test.sh asserts
+every port here against the containerPorts of the pod spec this policy
+selects.

+The Gateway-API alternative to freesailarr.ingress.yaml (Gitea #114). Form and
+reasoning: template-chart/templates/xxx.httproute.yaml and README, "Ingress and
+Gateway API".
+
+Only HTTPRoutes with parentRefs. No Gateway, no gatewayClassName, no
+Certificate, and no implementation-specific policy object - that subset looks
+identical on nginx-gateway-fabric, Cilium, Envoy Gateway and Istio, which is
+the whole reason the cluster's implementation can be swapped without touching
+this chart. Class and certificate therefore belong to the PLATFORM, on the
+Gateway and its listeners. ingress.clusterIssuer, ingress.className,
+ingress.annotations and their per-app overrides are all inert in this mode.
+
+THE SAME TWO SHAPES AS THE INGRESS, AND THEY STILL MIX
+
+  1. One host per app (the default): every published app gets its own
+     HTTPRoute with its own hostname, pointing at its own app's Service.
+  2. One shared domain with sub-paths (ingress.host): the apps that carry no
+     host of their own move into ONE route with one rule each.
+
+THIS CHART HAS NO ingress.domain, SO httpRoute HAS NO hostnames
+
+It is the documented exception on that point (README, guideline 4): the chart
+bundles ten independently exposed apps, so there is no single hostname to put
+in a chart-global list - a hostnames entry could not say which app it belonged
+to. The hostnames therefore come from the values that already hold them,
+ingress.host and <app>.ingress.host, which keeps the single source of truth the
+convention is actually about. Those two are not Ingress switches: they name the
+public addresses of this release, and both modes read them.
+
+Consequence for a migration: the "second hostname" the convention offers
+elsewhere is done here by changing <app>.ingress.host, which in Gateway mode
+feeds only the route - there is no Ingress rendered to disagree with it.
+
+WHERE THE GATEWAY API IS BETTER THAN WHAT IT REPLACES, AND IT IS NOT A
+TRANSLATION
+
+qBittorrent has no base-path setting: it serves its WebUI at the root and the
+proxy has to strip the prefix. nginx applies rewrite-target per INGRESS OBJECT
+and not per path, and the other apps must NOT be rewritten - their UrlBase
+contains the prefix, so they expect the full path. That is why
+freesailarr.ingress.yaml splits qBittorrent into a SECOND Ingress object on the
+same host, which then has to
+
+  - repeat the same TLS secret name as the main object, so that neither object
+    depends on an assumption about whether nginx applies the other one's TLS
+    configuration to its paths,
+  - OMIT the cert-manager annotation so only one Certificate is requested for
+    that one secret - except when no main object renders at all, which is a
+    conditional inside the annotation block, and
+  - match on an ImplementationSpecific path with a regex
+    ("<path>(/|$)(.*)") whose capture group 2 the rewrite refers to.
+
+The Gateway API's URLRewrite filter is per RULE. All of that disappears: one
+route, one rule per app, and qBittorrent's rule carries the filter while its
+neighbours do not. The path match goes back to a plain PathPrefix, there is no
+second object, no duplicated TLS block, no conditional annotation and no
+regex. The convention's own summary says rewrite-target "has a real
+equivalent"; in this chart the equivalent is strictly less machinery than the
+original, and that is the reason this chart was worth converting rather than
+merely translating.
+
+qBittorrent is the one app that contributes a SECOND rule, and it is not part
+of the rewrite: a 301 from the bare, slashless prefix to the slashed form
+(Gitea #118). Without it qBittorrent answers 200 under a URL whose relative
+links resolve to the host root, which on the shared host is a DIFFERENT
+application. In Ingress mode the chart does not render that redirect - it
+cannot, as the only mechanism nginx offers for it is a snippet annotation that
+most clusters refuse (values.yaml, qbittorrent.ingress, has the full price).
+This is therefore the one place where the Gateway mode is not merely less
+machinery but closes a gap the Ingress mode leaves open.
+
+WHAT IS NOT BETTER: ANYTHING THAT WAS AN ANNOTATION AND IS NOT A FILTER. The
+per-app and global ingress.annotations have no counterpart at all here. This
+chart sets no body-size annotation of its own, so nothing it NEEDS is lost -
+but an operator who added one through ingress.annotations (qBittorrent takes

+
+           A request for the bare qbittorrent.ingress.path - "/qbittorrent"
+           by default, no trailing slash - is matched by the PathPrefix rule
+           above and the URLRewrite turns it into "/". That is a valid
+           request to qBittorrent, which answers 200 with its login
+           page, so nothing anywhere reports a problem. But the browser's
+           document URL stays prefixless, and a relative link in that page
+           resolves against the PARENT of that path - which is the host root.
+           Every asset, every XHR and every form target therefore goes to "/",
+           and "/" on this shared host is SEERR. The symptom is qBittorrent's
+           login page that is unstyled and does nothing, while the requests it
+           makes are answered by a different application entirely - and seerr
+           answering a qBittorrent request is not a clue anyone follows
+           quickly. One redirect to the slashed form fixes all of it, because
+           relative links then resolve against the slashed prefix.
+
+           PRECEDENCE IS NOT POSITION. This rule is matched by the Gateway API
+           on an Exact path, and the specification ranks "Exact path match"
+           ABOVE "Prefix path match with largest number of characters", with
+           list order consulted only when every earlier criterion ties
+           (gateway-api v1.6.3, apis/v1/httproute_types.go). So this rule wins
+           over the PathPrefix rule above AND over seerr's PathPrefix "/" no
+           matter where it is emitted. The length-descending sort of the rules
+           in this route therefore stays what the header says it is - a
+           deterministic, reviewable rendering - and emitting this rule
+           directly after the one it corrects is a readability choice, not a
+           correctness one.
+
+           301 AND NOT 308, deliberately, and the reason is not the HTTP
+           semantics but which values an implementation is obliged to support.
+           The Gateway API marks 301 and 302 as CORE and everything else -
+           308 included - as EXTENDED. An implementation that does not support
+           the value given here must set the Accepted condition of the ROUTE to
+           status False with reason UnsupportedValue: not of this rule, of the
+           whole object. On the shared host that is one route carrying every
+           app under it, so a 308 that one implementation declines takes
+           prowlarr, radarr, sonarr and seerr down with qBittorrent - and it
+           does so on a route that is schema-valid, in a status field no
+           controller writes in CI. It would also contradict decision 1 of
+           Gitea #114, which is that this chart renders only the subset
+           that looks identical on nginx-gateway-fabric, Cilium, Envoy
+           Gateway and Istio, so that the cluster's implementation can be
+           swapped without touching the chart.
+
+           What 308 would buy is method and body preservation, and this rule
+           does not need it: it fires on exactly one path, the prefixless entry
+           to the WebUI, which a browser reaches with GET. qBittorrent's API
+           lives under "<path>/api/..." - slashed, longer, and therefore
+           served by the PathPrefix rule above, which this rule never sees. A
+           POST to the API is not redirected at all, so there is no body to
+           lose.
+
+           statusCode MUST BE WRITTEN OUT: it defaults to 302 in the API, and
+           a temporary redirect here would be re-fetched by every client on
+           every visit forever, for a prefix that is a permanent property of
+           this release's layout.
+
+           THE ONE ASYMMETRY TO THE nginx SNIPPET (values.yaml, qbittorrent):
+           HTTPRequestRedirectFilter has exactly five fields - scheme,
+           hostname, path, port, statusCode - and says nothing about the query
+           string, while ReplaceFullPath is specified as replacing the full
+           PATH. The nginx remedy in Ingress mode appends "$is_args$args" and
+           so carries the query over explicitly; here the query's fate is left
+           to the implementation and is not something this chart can state.
+           It costs nothing on the path this rule actually serves - the UI
+           entry point takes no query parameters - but it is a real difference
+           and not a translation. */}}

+{{- /*
+NetworkPolicy for freesailarr (Gitea #5).
+
+TEN CONTAINERS IN ONE POD, BEHIND A VPN, AND THE POLICY IS SIMPLER THAN THAT
+SOUNDS - for one reason worth stating first: the containers talk to each other
+over LOCALHOST. They share a network namespace, so none of that traffic ever
+reaches a network interface and NO NetworkPolicy has anything to say about it.
+Prowlarr reaching Radarr, Recyclarr reaching Sonarr, every one of those hops is
+invisible here. What this policy governs is only what enters or leaves the pod.
+
+INBOUND is the eight published web interfaces plus gluetun's health server, and
+almost all of them are probe ports - the kubelet opens an HTTP connection to
+each container's own interface - so they are one rule on the probe path. The
+newznab port of mediathekarr is the exception: nothing probes it, and its only
+consumer is Prowlarr in this same pod over localhost, so it is restricted by
+source and that costs nothing.
+
+OUTBOUND IS WHERE THIS CHART IS UNLIKE EVERY OTHER ONE HERE, because the pod's
+network namespace belongs to gluetun. Every connection the *arr containers make
+goes into the WireGuard tunnel and leaves the pod as UDP to the VPN endpoint -
+so a NetworkPolicy sees the OUTER packets and almost nothing else. Three rules
+cover it: DNS, UDP 51820 for the tunnel itself, and 443 for gluetun's own
+server-list API. Indexer and tracker traffic needs no rule of its own; it is
+already inside the tunnel.
+
+AND THE TUNNEL RULE IS THE ONE THAT CAN BREAK THIS CHART, which is also why it
+is well covered: gluetun's health server returns 200 only while the tunnel is
+up, and all three of its probes address it. A blocked UDP 51820 therefore means
+a pod that never becomes Ready - visibly, in the install-test, which brings up
+a real tunnel. 51820 is WireGuard's standard port and Mullvad's; Mullvad also
+offers 53, 123, 500 and 4500 for obfuscation, and a release using one of those
+needs networkPolicy.egress.extraPorts. Note that extraPorts is TCP only, so an
+alternative UDP port needs the rule here widened instead - said plainly,
+because it is a limit of the shared values shape and not an oversight.
+
+WHAT THIS OBJECT IS: a ceiling on reachability, not an authentication layer.
+Only the ports declared below are reachable at all - whatever else the process
+binds, now or after the next app update, is blocked without anyone having to
+notice it exists.
+
+WHAT IT IS NOT:
+  - EGRESS IS COARSE. A NetworkPolicy matches CIDRs and selectors and NEVER
+    hostnames, so "only to the database host" cannot be expressed at all. This
+    cluster's CNI is Canal (Flannel plus Calico for policy) and has no FQDN
+    rule; Calico's GlobalNetworkSet could express one but would bind this chart
+    to Calico, the same argument that kept implementation-specific objects out
+    of the Gateway-API sweep (#114). Each egress rule therefore permits its
+    PORT to any destination.
+  - NOT A BOUNDARY WHERE THE CNI DOES NOT ENFORCE ONE. An unenforced policy is
+    accepted by the API server and filters nothing, so everything reads as
+    configured while nothing is filtered.
+  - THE REASONING IS IN TEMPLATE COMMENTS, not in "#" comments: those are part
+    of the rendered object, travel into the cluster and appear in every release
+    diff. ci/run-networkpolicy-test.sh fails on a rendered "#".
+
+THE PORT NUMBERS BELOW ARE POD PORTS, NEVER NODEPORTS. A NetworkPolicy is
+evaluated at the pod's network interface, after kube-proxy has already
+translated a NodePort to the targetPort, so a NodePort number here would match
+nothing while looking strict - and, being the only rule for that port, would
+block every inbound connection instead. ci/run-networkpolicy-test.sh asserts
+every port here against the containerPorts of the pod spec this policy
+selects.

+  or at its implementation's own policy object, next to the Gateway and not
+  here.

+Only an HTTPRoute with parentRefs. No Gateway, no gatewayClassName, no
+Certificate, and no implementation-specific policy object - that subset looks
+identical on nginx-gateway-fabric, Cilium, Envoy Gateway and Istio, which is
+the whole reason the cluster's implementation can be swapped without touching

+OFF BY DEFAULT, AND SO IS THE INGRESS. This chart publishes nothing unless
+asked (ingress.enabled: false, httpRoute.enabled: false), because the consumer
+it was built for speaks S3 inside the cluster. Both routing modes are therefore
+a values change, and both expose THE S3 API - not a web UI. Garage's admin API
+is JSON and its authenticated half is closed in this chart, and the project's
+web interface is a separate program that is not in this image. Whoever turns
+either mode on is putting an S3 endpoint on the internet; it authenticates
+every request with a signature, and the credentials are the two fields of the
+s3 vault item.
+
+WHAT CHANGES FOR ingress.domain, AND IT IS THE ONE CLAIM THIS FILE INVALIDATES
+
+garage.ingress.yaml used to be able to say that NOTHING outside it reads
+ingress.domain, so that switching the Ingress off freed domain as well as
+clusterIssuer. This file is now a second reader (when httpRoute.hostnames is
+empty), so the sentence holds only while BOTH modes are off. That is corrected
+in that template's header and in values.schema.json rather than left standing.
+
+Unchanged: garage.s3.rootDomain is still its own value and still not coupled to
+ingress.domain. A wildcard vhost suffix for bucket addressing and the single
+host a route answers on are different things, and the Gateway API does not make
+them the same.

+                (see garage.service.yaml), and it gets the narrowest rule this

+Only the ports declared below are reachable at all - whatever else the process

+WHAT IT IS NOT:
+  - EGRESS IS COARSE. A NetworkPolicy matches CIDRs and selectors and NEVER
+    hostnames, so "only to the database host" cannot be expressed at all. This
+    cluster's CNI is Canal (Flannel plus Calico for policy) and has no FQDN
+    rule; Calico's GlobalNetworkSet could express one but would bind this chart
+    to Calico, the same argument that kept implementation-specific objects out
+    of the Gateway-API sweep (#114). Each egress rule therefore permits its
+    PORT to any destination.
+  - NOT A BOUNDARY WHERE THE CNI DOES NOT ENFORCE ONE. An unenforced policy is

+NetworkPolicy for gotenberg (Gitea #5).
+
+Gotenberg here is a cluster-internal service: no Ingress, and its consumers are
+other pods (paperless-ngx converts mail HTML to PDF through it).
+
+EGRESS IS DNS ONLY BY DEFAULT, AND THAT IS A DELIBERATE, VISIBLE TRADE rather
+than an oversight. Gotenberg drives a headless Chromium, so an egress rule for
+80 and 443 would let anything that can POST to this service fetch arbitrary
+URLs through it - a textbook SSRF pivot, and the pod is reachable from the
+whole cluster by default because 3000 is the probe port. Blocking it costs the
+remote-asset half of HTML conversion: a converted page keeps its EMBEDDED
+content and loses the images it would have FETCHED, which degrades a PDF rather
+than failing a pod. The degradation is silent, which is why it is named here, in
+values.yaml and in NOTES.txt.
+
+A deployment that needs those images sets networkPolicy.egress.remoteAssets:
+true - a named switch rather than a line in extraPorts, so the trade is a
+decision someone made and not a port number nobody can place. Its default is
+off, because restrictive-by-default is the convention and the deployment is
+where reality is accommodated. The long form of what it buys, and of the one
+thing about it that was NOT verified, is on the rule itself.
+
+WHAT THIS OBJECT IS: a ceiling on reachability, not an authentication layer.
+Only the ports declared below are reachable at all - whatever else the process
+binds, now or after the next app update, is blocked without anyone having to
+notice it exists.
+
+WHAT IT IS NOT:
+  - EGRESS IS COARSE. A NetworkPolicy matches CIDRs and selectors and NEVER
+    hostnames, so "only to the database host" cannot be expressed at all. This
+    cluster's CNI is Canal (Flannel plus Calico for policy) and has no FQDN
+    rule; Calico's GlobalNetworkSet could express one but would bind this chart
+    to Calico, the same argument that kept implementation-specific objects out
+    of the Gateway-API sweep (#114). Each egress rule therefore permits its
+    PORT to any destination.
+  - NOT A BOUNDARY WHERE THE CNI DOES NOT ENFORCE ONE. An unenforced policy is
+    accepted by the API server and filters nothing, so everything reads as
+    configured while nothing is filtered.
+  - THE REASONING IS IN TEMPLATE COMMENTS, not in "#" comments: those are part
+    of the rendered object, travel into the cluster and appear in every release
+    diff. ci/run-networkpolicy-test.sh fails on a rendered "#".
+
+THE PORT NUMBERS BELOW ARE POD PORTS, NEVER NODEPORTS. A NetworkPolicy is
+evaluated at the pod's network interface, after kube-proxy has already
+translated a NodePort to the targetPort, so a NodePort number here would match
+nothing while looking strict - and, being the only rule for that port, would
+block every inbound connection instead. ci/run-networkpolicy-test.sh asserts
+every port here against the containerPorts of the pod spec this policy
+selects.

+
+      - EMBEDDED images are MIME parts INSIDE the file. Neither Tika nor
+        Gotenberg needs the network for them, which is why apache-tika stays
+        DNS-only and why this switch is not needed for a mail that carries its
+        pictures with it.
+      - REMOTE images (<img src="https://..."> in the mail body) are fetched by
+        CHROMIUM, here, at render time. With this switch off they are silently
+        dropped: the PDF is produced, it is just missing them. Nothing fails,
+        nothing is logged by this chart, and no probe notices.
+
+    NOT CHECKED, and not claimed: whether paperless-ngx re-embeds the images
+    Tika extracted before handing the HTML over. If it does not, embedded
+    images would be lost as well - but that would be pre-existing paperless
+    behaviour and not this policy, so do not read the switch as a fix for it.
+
+    WHY IT IS A SWITCH AND NOT THE DEFAULT. Gotenberg drives a headless
+    Chromium and 3000 is its probe port, so the service is reachable from the
+    whole cluster by default. Allowing 80/443 outbound therefore turns anything
+    that can POST here into a way of fetching arbitrary URLs - an SSRF pivot
+    with the cluster's whole internal address space behind it. That argument is
