A ServiceDefinition could not say it needs the host's Intel QuickSync render
device. The schema is `additionalProperties: false`, so there was no authorable
form for it at all, and `apps/` is generated — a hand-edit would be reverted by
the next render.
Adds optional top-level `hardware`, with one optional member `gpu`, an enum
whose only current value is `intel-quicksync` (schema 1.7.0 -> 1.8.0).
The enum is the point. The SD declares WHAT CLASS of device it needs; the
hostPath, the mount and the GID live only in catalog/render.py. Migrating to
the Intel GPU device plugin (`gpu.intel.com/i915` resource requests, no
hostPath) is then a renderer change with zero catalog edits. Letting an SD name
`/dev/dri` directly would look simpler and make that migration a catalog-wide
edit, so both the schema description and the renderer contract say so
explicitly.
When `hardware.gpu == intel-quicksync`, r_deployment emits, on the app
container / pod spec only:
- a hostPath volume `dri` -> /dev/dri, type DirectoryOrCreate;
- a read-write volumeMount of it at /dev/dri (VA-API opens the render node
read-write, so deliberately not readOnly);
- INTEL_RENDER_GID MERGED into podSecurityContext.supplementalGroups, never
clobbering what the SD already declares.
`DirectoryOrCreate` is load-bearing. A node that comes back without the render
device (rebuild, BIOS change, driver regression, hardware swap) must degrade
the workload to software transcoding, not fail the mount: apps-wave-0 is
`wait: true` and apps-wave-1 dependsOn it, so a failed hostPath mount stalls
the whole app tier for a feature that is not load-bearing. /dev is tmpfs, so
the empty directory the kubelet creates leaves nothing durable behind. Its cost
— a missing device is silent, and no metric exists to alert on — is recorded in
the contract rather than papered over with an alert that could not fire.
Deliberately NOT emitted: no `privileged: true` (Kyverno restrict-host-
namespaces is Enforce and it is not needed), no nodeSelector (placement is a
separate concern with its own justification), no resource requests (there is no
app-container resource render path).
INTEL_RENDER_GID = 992 is a single named constant carrying its provenance:
measured on all three prod nodes on 2026-09-30, and a *systemd dynamic*
allocation rather than a static GID, so a node rebuild can move it.
No catalog entry uses the field. Re-rendering `--all catalog -o apps` is a zero
diff, which is the proof the change is inert until opted into.
Three self-test cases in the existing check(...) style: the positive, the
negative (an SD without `hardware` gains no volume, no mount, no
securityContext — mirroring the podSecurityContext negative) and the merge case
([44] + 992 -> [44, 992], fsGroup preserved). Note that NO gate stage runs
`render.py --selftest`; they were run by hand and the gap is recorded in the
handoff.

"description": "Operator-facing onboarding contract for the home k3s + Longhorn platform. One ServiceDefinition per file under catalog/. Captures INTENT; the platform compiles it into concrete resources (see schemas/renderer-contract.md). Canonical source of truth: spec docs/13-service-catalog.md. Serves R-GITOPS-02; ties into R-NET-*, R-STATE-*, R-TLS-*, R-DNS-*, R-OBS-*, R-UPD-*, R-IDP-*. Schema version: 1.8.0 (adds optional `hardware` - a host HARDWARE CAPABILITY declaration for the container kind, currently one member: `hardware.gpu: intel-quicksync`, meaning the workload needs the host iGPU render device for hardware video transcode. It is an ENUM OF INTENT, not a device path: the renderer satisfies it today with a /dev/dri hostPath volume (`DirectoryOrCreate`), a read-write /dev/dri volumeMount on the app container, and the host `render` GID merged into podSecurityContext.supplementalGroups, and a later move to the Intel GPU device plugin is then a render.py change with no catalog edit. Renders NOTHING when absent, so every existing app stays byte-identical. Emits no privileged securityContext (Kyverno restrict-host-namespaces would reject it and it is not needed), no nodeSelector (node placement is a separate concern with its own justification) and no resource requests). 1.7.0 (no field changes; a MAPPING change to `exposure`, which had never had an effect on DNS. `exposure: internal` now renders ExternalDNS's own controller annotation onto every HTTPRoute it emits, set to a value other than `dns-controller`, so external-dns (v0.21.0, source/gateway.go -> annotations.IsControllerMismatch) skips the route before resolving any hostname and the service is INCAPABLE of producing a public record. Both docs/09 R-DNS-03 and schemas/renderer-contract.md already said `internal` renders no public DNS record; nothing enforced it, and six internal services -- jackett, pihole, qbittorrent, radarr, semaphore, sonarr -- were publishing `<name>.home.keithjackson.dev` into the PUBLIC Cloudflare zone answering with the RFC1918 Gateway VIP, which published the internal subnet and a full service inventory and made each name a DNS-rebind primitive. Enforced on every gate run by conformance/tests/l0-static/internal-services-publish-no-public-dns). 1.6.0 (splits `observability.metrics` from WHERE metrics live: adds optional `metricsEndpoint` (port/name/path/interval) and optional `livenessWorkload` (kind/name). `metrics: true` previously rendered a ServiceMonitor hardcoded to a port named `metrics` that no rendered Service ever defined, so all twelve app monitors discovered ZERO targets and every `up{job=...}` SLI was structurally inert on prod; a monitor is now rendered only from a declared `metricsEndpoint`, which also renders the Service port and the monitoring-namespace ingress allow, and the `up` SLI is expressed against kube-state-metrics -- a signal that exists for every workload without a per-app exporter. `livenessWorkload` names the object whose readiness IS the service, for the case where the running workload is not the one this SD renders). 1.5.0 (adds optional `inClusterClients` — additional in-cluster clients, named by NAMESPACE, admitted to a declared port of this service DIRECTLY, bypassing the shared Gateway. `ingressRoutes` admits only the Gateway proxy identity and `dependencies` only links catalog services, so a PLATFORM controller dialling a Service ClusterIP had no authorable form at all; that gap is what deadlocked prod's GitOps when its GitRepository moved to the in-cluster Gitea Service. Renders one least-privilege ingress CiliumNetworkPolicy per entry — the named namespace and the declared port, nothing wider). 1.4.0 (makes the `bulk` tier REAL: a bulk storage entry now carries `export` (the absolute NFS export path on the ${BULK_NFS_SERVER} host) and renders a STATIC, pre-bound NFS PersistentVolume + PVC over data that already exists outside the cluster, plus optional `subPath` and `readOnly` on any entry. Resolves the OQ-2 bulk-backing stub for STATIC pre-existing datasets; dynamic bulk provisioning remains unimplemented and unneeded). 1.3.0 added optional pod-level podSecurityContext for the container kind — k8s PodSecurityContext emitted verbatim onto the pod spec; its fsGroup unblocks non-root images e.g. semaphore/UID-1001 writing a mounted Longhorn PVC). 1.2.0 added optional per-container env/envFrom/lifecycle for the container kind — k8s EnvVar/EnvFromSource/Lifecycle shapes emitted verbatim onto the app container; unblocks headless-install/DB-backed apps e.g. gitea/nextcloud/semaphore/unifi/minecraft. 1.1.0 added the shape invariant exposure:public => auth.mode!=none (docs/13 v1.1 / docs/15 / R-IDP-02).",
