fix(keycloak): one owner for the keycloak ServiceMonitor (26.8 operator 409 loop blocks Flux)

The 26.x Keycloak operator creates its own ServiceMonitor named after the
CR (keycloak/keycloak) when metrics are enabled; spec.serviceMonitor.enabled
defaults true. That collides with the Flux-owned platform/keycloak/
servicemonitor.yaml: the operator's PATCH 409s, it exhausts retries, the CR
stays Ready=False/HasErrors=True, and platform-config (wait: true) stalls
every downstream Kustomization.

Keep the repo's ServiceMonitor (conformance L0/L2 and the dashboard are
written against it; the operator's scrapes the same port 9000 /metrics) and
set spec.serviceMonitor.enabled: false.

+---
+
+## What changed
+
+- `catalog/gitea.yaml`: `source.image` `gitea/gitea:1.27.3` -> `gitea/gitea:28.3.0` (still the
+  newest stable tag on Docker Hub and GitHub on 2026-11-07: 28.0.0, 28.1.0, 28.2.0, 28.3.0).
+  `update.range` `">=1.22.0 <2.0.0"` -> `">=28.0.0 <29.0.0"`.
+- 28.x breaking changes handled in the env block:
+  - `GITEA__server__DOMAIN` **removed**: 28 no longer reads `[server] DOMAIN` (go-gitea/gitea#39400);
+    `ROOT_URL` was already set and is now the only source of the domain. Nothing else in the repo
+    reads the variable (the bootstrap script sets ROOT_URL/SSH_PORT only).
+  - `GITEA__actions__RUN_RETENTION_DAYS=400` **declared** (go-gitea/gitea#38855 added the 400-day
+    default; the spec repo states no CI-history retention requirement).
+  - `GITEA__security__EGRESS_MODE=lax` **declared, with no allow list.** Read from the 28.3.0
+    source: the Keycloak OIDC login source does NOT go through the new egress policy (goth's
+    openidConnect provider, default HTTP client). The policy covers webhooks, the OAuth2 avatar
+    fetch (`UPDATE_AVATAR` is off) and OpenID 2.0. A hostname entry would not even help for a
+    private address — `WithLocalNeedsIPAllow` requires an IP/CIDR entry. So the brief's
+    "Keycloak SSO breaks" premise does not hold for 28.3.0, and an allow-list entry would only
+    widen webhook SSRF reach.
+  - `GITEA__service__DISABLE_REGISTRATION=true` **declared** (28's new default; 1.27 defaulted it
+    open). OAuth2 auto-registration is gated separately and keeps working.
+- `update.autoRollbackOnFailedHealth`: kept `true`, commented as **inert**. It renders only an
+  annotation on a Flux ImagePolicy, and `apps/` is rendered `--no-image-automation`, so no
+  ImagePolicy exists. The Deployment is `Recreate` with no probes, so nothing reverts the image
+  automatically. Rollback = restore the PVC, never an image revert onto the migrated DB.
+- `apps/wave-0/gitea.yaml` re-rendered with the canonical command
+  (`render.py --all catalog -o apps --wave-layout --no-image-automation`, in the toolbox). Only
+  gitea changed.
+- `renovate.json5`: gitea `allowedVersions` `<2.0.0` -> `<29.0.0`; the description no longer calls
+  28.x a stale tag.
+
+## What I verified
+
+- Docker Hub tag list and GitHub tags: 28.3.0 is the newest 28.x stable tag.
+- Read the v28.3.0 source: `modules/egress/policy/policy.go`, `modules/egress/policies.go`, every
+  `egress.New*` caller, `services/auth/source/oauth2/providers_openid.go`,
+  `modules/setting/{security,actions,service}.go`, `routers/web/auth/{oauth,linkaccount}.go`,
+  `cmd/admin_user_list.go`, `cmd/admin_auth*.go`, the Dockerfile, and `docker/root` (the s6 setup
+  still runs `environment-to-ini`). The postStart hook's CLI is unchanged in 28.3.0: `admin user
+  list --admin` still has Username in column 2, `admin auth list` still has ID/Name in columns 1/2,
+  `add-oauth`/`update-oauth` keep the same flags, and curl and su-exec are still in the image.
+- Live Gitea (API, 2026-11-07): version 1.27.3. Zero repo, org and system webhooks, no mirrors.
+- `renovate-config-validator` at 44.167.0 (the tag renovate.yaml pins): "Config validated
+  successfully".
+- Ran the toolbox gate on the committed tree (numbers are in the PR).
+
+## What I did NOT verify
+
+- **The upgrade itself.** Nothing booted 28.3.0 against a copy of the production DB. Migration
+  time, migration success and the post-upgrade SSO login are all UNVERIFIED, and the PR's
+  post-merge checklist covers them.
+- **The age of the latest gitea-data Longhorn/off-cluster backup.** The cluster read failed from
+  the worktree (no k3s-prod context with the kubeconfig available), so the operator must confirm
+  it before merging.
+- How the Envoy Gateway handles the new `/-/ws` WebSocket. If upgrades are not forwarded, live
+  notifications fall back to polling (not breaking). UNVERIFIED.
+- Whether the L2/L3 conformance suite passes. It does not run in CI.

+---
+
+## What changed
+
+**Incident.** PR #121 (Renovate) bumped `platform/keycloak/kustomization.yaml`'s three
+`keycloak-k8s-resources` URLs 26.0.6 -> 26.8.2. Upstream `kubernetes/` at 26.8.2 holds **four**
+CRDs, not two (GitHub contents API, `?ref=26.8.2`):
+
+| file | at 26.0.6 | at 26.8.2 |
+|---|---|---|
+| `keycloaks.k8s.keycloak.org-v1.yml` | yes | yes |
+| `keycloakrealmimports.k8s.keycloak.org-v1.yml` | yes | yes |
+| `keycloakoidcclients.k8s.keycloak.org-v1.yml` | — | **new** (v2alpha1) |
+| `keycloaksamlclients.k8s.keycloak.org-v1.yml` | — | **new** (v2alpha1) |
+| `kubernetes.yml` | yes | yes (now carries RBAC for both new kinds) |
+
+(`cluster-wide/` is a separate variant; upstream's own `kubernetes/kustomization.yml` lists exactly
+the five files above.) The 26.8.2 operator starts an informer for every controller it has and dies
+on the first missing kind: `Couldn't start informer for keycloaksamlclients.k8s.keycloak.org/v2alpha1
+... GET .../namespaces/keycloak/keycloaksamlclients ... Not Found`, exit 1, CrashLoopBackOff. Flux
+`platform` (`wait: true`, 5m) sat in health checks and every dependent Kustomization reported
+`dependency ... is not ready`. The old 26.0.6 ReplicaSet kept serving (RollingUpdate 25%/25%), so SSO
+stayed up.
+
+**Fix.**
+- `platform/keycloak/kustomization.yaml`: added the two CRD URLs, each with the same
+  `# renovate: datasource=github-tags depName=keycloak/keycloak-k8s-resources` marker (the repo's
+  custom.regex manager matches all five — checked by running its regex over the file). Header
+  comment updated to v26.8.2, plus a warning that Renovate cannot add a CRD a release introduces.
+- Same file: a `patches:` JSON6902 patch on Deployment `keycloak-operator`: memory limit
+  450Mi -> **768Mi**, request 450Mi -> **512Mi**. 450Mi is upstream's default (unchanged at 26.8.2,
+  so not something the bump changed). Evidence it is too small here: the 26.0.6 pod had **154
+  restarts**, `lastState.terminated.reason: OOMKilled` (exit 137, 2026-11-07T23:09:54Z), and
+  `kubectl top` showed **421Mi / 450Mi**. 26.8.2 runs four controllers instead of two on Quarkus
+  3.40.1.1 (was 3.15.1). No variable in the operator to disable watching unused kinds was used —
+  installing the CRDs is upstream's supported shape.
+- `platform/keycloak/README.md` "Upgrading Keycloak": the diff-the-CRD-list step; "three URLs" ->
+  "the release URLs". `renovate.json5`: same wording fix in a comment only.
+
+## What I verified
+
+- Upstream file lists at 26.0.6 and 26.8.2 (GitHub API) and `diff` of `kubernetes.yml` between the
+  two: the new kinds' ClusterRoles + RoleBindings ship in it, and the Deployment's resources are
+  still 450Mi/450Mi.
+- Live, read-only (`kubectl --context k3s-prod`, 2026-11-08 ~05:57Z): only `keycloaks` and
+  `keycloakrealmimports` CRDs installed; Deployment strategy RollingUpdate maxSurge/maxUnavailable
+  25%; RS `keycloak-operator-58dff6c4` (26.8.2) 0/1 CrashLoopBackOff, RS `78dbb75f64` (26.0.6) 1/1;
+  operator log is the informer error above; Flux `platform` `Healthy=Unknown` "Running health
+  checks for revision main@sha1:e8d2666"; no NetworkPolicy and no CiliumNetworkPolicy in ns
+  `keycloak`.
+- No sensitive path touched (`infra/gitea/approval-policy.json`), so this should merge on green.
+- Gate: see the PR body for the exact rc and stages of the run against the final commit.
+
+## What I did NOT verify
+
+- **That the 26.8.2 operator becomes Ready after this merges.** Only the two missing kinds were
+  observed failing; another start-up failure behind them is possible.
+- **That 768Mi is enough** — no 26.8.2 memory measurement exists yet; re-check `kubectl top` after
+  a week.
+- **The Keycloak server upgrade 26.0.6 -> 26.8.2 itself.** Once the operator runs it will roll
+  keycloak-0/1 and Keycloak migrates the DB schema. The CR's `spec.update.strategy` defaults to
+  `RecreateOnImageChange` — expect a **full SSO outage** while both pods recreate, not a rolling
+  one. Back up / confirm the latest CNPG backup first if that matters.
+- **The 26.8.2 Keycloak CRD's `spec.networkPolicy.enabled` defaults to `true`.** The operator will
+  create a NetworkPolicy selecting the Keycloak pods (first policy in that namespace). With no
+  `from` lists set it allows all sources on the HTTP/management ports, so Gateway, ServiceMonitor
+  and the reconciler Jobs should still reach it — but this was read from the CRD text, not observed.
+- **The passkey reconciler's 26.0.6 Admin API assumptions against 26.8.2** (README "Upgrading
+  Keycloak" list) — not re-checked here; PR #121 merged without it.
+- `catalog/keycloak.yaml`'s documentation-only image tag was not updated.

+---
+
+## What changed
+
+- `platform/keycloak/keycloak-instance.yaml`: added `spec.serviceMonitor.enabled: false`.
+  The 26.x Keycloak operator creates its own ServiceMonitor, named after the CR (`keycloak/keycloak`),
+  whenever `metrics-enabled=true` and the ServiceMonitor CRD exists. `serviceMonitor.enabled` defaults
+  to `true` in the 26.8.2 CRD, both in v2alpha1 and in v2beta1 (v2beta1 is now the storage version).
+  That is the same name and namespace as the repo's Flux-owned `platform/keycloak/servicemonitor.yaml`.
+  After the 26.0.6 -> 26.8.2 bump (#121/#144) the operator's PATCH against it returned
+  `409 Conflict` and it ran out of retries. The CR then sat at `Ready=False`/`HasErrors=True`, and
+  `platform-config` (`wait: true`, which health-checks every object it applies, this CR included)
+  blocked everything that `dependsOn` it: velero, apps-vms, apps-wave-0 (and so waves 1/2 and
+  pm-agent), homepage, oauth2-proxy, headlamp, conformance, vpn-ingress, crafty, runbooks.
+- `platform/keycloak/servicemonitor.yaml`: a comment saying it is the sole owner.
+- **Why ours is kept:** these are written against it: the L0 `servicemonitor-ports-resolve`
+  allow-list entry `platform/keycloak/servicemonitor.yaml:keycloak`, the L2 `keycloak-monitored`
+  chainsaw test, the README's ownership table, and the dashboard's `up{namespace="keycloak"}`.
+  The operator's version (upstream `KeycloakServiceMonitorDependentResource` @26.8.2) scrapes the same
+  target: port name `management` (9000 on `keycloak-service`), path `/metrics`, interval 30s,
+  selector = the operator's instance labels. It offers nothing ours lacks, so having two owners
+  would add a fight and gain nothing.
+
+## What I verified
+
+- Live, read-only, `k3s-prod` ~06:25Z: the CRD schema field `spec.serviceMonitor.enabled`
+  (`default: true`) exists in both served versions. The live `keycloak` ServiceMonitor has exactly
+  **one** managedFields manager, `kustomize-controller` (Apply, 2026-09-05), **no ownerReferences**,
+  and labels `kustomize.toolkit.fluxcd.io/name=platform-config`, `release=kube-prometheus-stack`. So
+  the operator's apply never landed, and nothing on the object ties it to the Keycloak CR.
+- The ServiceMonitor will not be deleted when the operator is switched off: the operator's dependent
+  informer is filtered on `Constants.DEFAULT_LABELS_AS_STRING`
+  (`app.kubernetes.io/managed-by=keycloak-operator`). Our object does not carry that label and has
+  no ownerReference, so the operator cannot see it as its secondary and cannot delete or GC it.
+  This conclusion comes from reading the code. It was not observed.
+- The other operator dependents in ns `keycloak` do not collide with anything: `keycloak-service`,
+  `keycloak-discovery`, the StatefulSet `keycloak`, `keycloak-initial-admin`, and
+  `keycloak-network-policy` (owner Keycloak, no Flux label). The repo declares none of these names.
+  It only *references* `keycloak-service` by name (HTTPRoute, reconcilers). There are no PDBs in the
+  namespace, and the Ingress is already `enabled: false`. The only NetworkPolicy in the namespace is
+  the operator's. The repo has no Keycloak NetworkPolicy, and no Kyverno-generated default-deny is
+  present there. NetworkPolicies add up, so the operator's allow-policy cannot fight another owner.
+  Left at its default.
+- Local gate: see the PR body. It records the rc and stages.
+
+## What I did NOT verify
+
+- That the CR reaches `Ready=True`/`HasErrors=False` after merge. The status also says
+  "Performing Keycloak upgrade, scaling down the deployment". I am inferring that this half clears
+  once the workflow stops erroring. It is not proven.
+- That the operator stops issuing the PATCH once `enabled: false` is applied. Watch the operator
+  logs for 409.
+- That `platform-config` and its downstream Kustomizations go Ready on the new revision, and that
+  Prometheus keeps exactly one `serviceMonitor/keycloak/keycloak/0` pool with targets up.
+- The operator's actual label set for `DEFAULT_LABELS_AS_STRING`. I took it from the observed labels
+  on operator-created objects, not from `Constants.java`.

+---
+
+## What changed
+
+- **`renovate.json5`: the deprecated top-level `"docker": {"enabled": true}` is hand-migrated** to
+  `packageRules[0] = {"matchCategories": ["docker"], "enabled": true}`, the exact shape Renovate's
+  own migration produced on `origin/renovate/migrate-config` (PR #139). Its comment moved with it.
+  This replaces #139, which was closed because its rewrite deleted every comment in the file. No
+  other comment was removed or reflowed (diff is additions plus the moved block).
+- **`gitea/runner` added to the blast-radius rule** beside `gitea/act_runner`, with a comment:
+  act_runner was renamed upstream to gitea/runner after 0.6.1; Renovate does not follow renames,
+  so the actual image migration is a separate manual PR.
+- **Two new packageRules for flux/helm `>=A <B` ranges:** `rangeStrategy: "bump"`, plus
+  `matchUpdateTypes: ["bump"] -> enabled: false`, so in-range releases (which Flux adopts on its
+  own) do not become PRs. Cause of the bug, from the 44.167.0 source: rangeStrategy is unset
+  (`auto`); the flux manager has no `getRangeStrategy`/`updateLockedDependency`, so
+  `lib/modules/manager/index.ts getRangeStrategy` resolves `auto` to `replace`; helm versioning is
+  the npm api verbatim, and npm `getNewValue` under `replace` turns `>=1.12.0 <1.13.0` into
+  `<1.14.0` (what PRs #131, #130 and #115 did).
+- **`platform/headlamp/helmrelease.yaml`: `version: "<0.47.0"` -> `">=0.46.0 <0.47.0"`**, comment
+  refreshed. The live chart is 0.46.0, so the set of installable charts is unchanged.
+
+## What I verified
+
+- **Semantic diff of #139:** I parsed `renovate.json5` on `origin/renovate/migrate-config` and on its
+  parent `5b484f6` with json5 (the copy inside the renovate image). With `docker` removed from the
+  parent and `packageRules[0]` removed from the migrated file, the two are identical. So the only
+  change was `{"matchCategories":["docker"],"enabled":true}`, inserted at packageRules[0].
+- **Validator, `ghcr.io/renovatebot/renovate:44.167.0`** (the tag that `.gitea/workflows/renovate.yaml`
+  pins as `container.image`): `renovate-config-validator` gives `Config validated successfully`
+  (rc 0), and so does `--strict` (rc 0), both as a file path and in repo mode. **`--strict` on

+## What I did NOT verify
+
+- **I have not seen a real scheduled Renovate run against this repo with this config.** The claim that
+  Renovate stops reopening the migrate-config PR rests on the validator and on `No config migration
+  necessary` in the local dry run, not on the Gitea bot. After merge, watch the next run, and if
+  `renovate/migrate-config` is still on the remote, delete it.
+- **Under bump, the new lower bound is the release Renovate proposes**, e.g. `>=1.13.2 <1.14.0`, not
+  `>=1.13.0`. Flux still installs the newest release in the window. Ranges with other shapes keep the
+  default `replace`: `3.9.x`, `~`, ceiling-only, and exact pins.
+- **The open PRs #131, #115 and any others still carry unbounded `<X` values.** They were generated
+  under the old strategy, and Renovate should rebase or regenerate them under bump on its next run.
+  I have not checked that it does.
+- The gitea/runner rename itself (a new image reference and any config changes) is not done here.
