PR #49 (merged 21c88b0) fixed the blocked scrape and it is verified working on prod
2026-10-05: all 6 targets up == 1, health=up, lastError='', lastScrapeDuration 0.001-0.006s
against 10.0s and "context deadline exceeded" before. oauth2_proxy_* is in the TSDB for
these namespaces for the first time (5 metric names, 148 series).
Four places in the tree still asserted the pre-fix state as current, in the present tense,
in the files a reader consults first:
platform/oauth2-proxy/podmonitor.yaml "READ THIS BEFORE BELIEVING THE TARGETS ARE UP:
THE SCRAPE IS CURRENTLY DENIED BY NETWORKPOLICY" and "SO THE TARGETS BELOW WILL READ
up == 0 UNTIL AN INGRESS ALLOWANCE LANDS". The first actively instructs the reader to
disbelieve a correct up == 1. Now a STATUS block with the post-fix numbers, with the
diagnosis kept below it under an explicit HISTORY heading because it is why the fix is
shaped the way it is.
catalog/render.py:159 "THIS IS THE PREREQUISITE ONLY, AND IT IS NOT YET SCRAPED".
catalog/render.py:1365 the same claim on the sidecar arg.
platform/oauth2-proxy/README.md its subsections are dated and so are honest records, but
a reader hits the stale body long before any correction. A SUPERSEDED pointer now sits
under the heading and an Update 2026-10-05 section carries the before/after.
The "not scraped" claims are corrected; the "a flag alone is not enough" warning is KEPT
deliberately, because that part is still true and "flag without ingress allowance" is
exactly what caused the 63.7h outage.
Two substantive errors fixed while there, not just tense. The README's "three things are
needed" listed a Service port and a ServiceMonitor — wrong, a PodMonitor targets pod ports
directly, which is why no Service exposes 44180 and the renderer needed no Service change;
following it would have sent someone to edit Service rendering for nothing. And
podmonitor.yaml deferred the fix to "the catalog/renderer, in flight on another branch" —
no such branch existed; it now names r_monitoring_ingress_policy, with a new CRAFTY section
explaining the one namespace this file cannot help.
Comments only in render.py, so the rendered output is byte-identical: no apps/ file and no
golden changes, and therefore no sensitive path and no human approval needed — the opposite
of the PR this documents.

catalog — ServiceDefinition entries (the onboarding surface)
One YAML file per service. Each file is a ServiceDefinition conforming to
../schemas/servicedefinition.schema.json. Adding or
editing a service here is the only onboarding step — the platform renders compute, storage, network
policy, egress, TLS, DNS, monitoring, and update policy from it (see
../schemas/renderer-contract.md). Serves R-GITOPS-02.
Source of truth for the initial catalog: spec
docs/13-service-catalog.md (14-service table +
SSO/egress/dependency intent).
Current examples
| File | docs/13 row | exposure | egress | auth | Notes |
|---|---|---|---|---|---|
pihole.yaml |
6 | internal | internet | forward-auth | admin UI behind oauth2-proxy; config on Longhorn (DR-critical); also platform DNS |
keycloak.yaml |
0 | public | internet | native | the IdP itself (own admin login + MFA); PostgreSQL on Longhorn; DR-critical |
The remaining catalog services (plex, sonarr, radarr, jackett, seerr, nextcloud, minecraft, unifi, semaphore, kasm, gitea, qbittorrent) are onboarded in later phases; they follow the same schema and inherit every guarantee automatically.
Authoring rules
- Only
nameandsourceare mandatory; every other field defaults to docs/13's default posture (kind: container,exposure: internal,egress: internet,auth.mode: forward-auth, stable auto-update, DNS-only default-deny). Set a field only to override the default. - Any exposed UI must have an
authblock:forward-auth(default) oroidc, each with a non-emptyauth.groups;native/noneare documented exceptions only. - Irreplaceable state (
class: longhornconfigs/DBs) must setbackup.policyto an off-cluster schedule — neverreacquirable(R-STATE-03). Only bulk media may bereacquirable. - Shell braces must be escaped
$${...}. Anything rendered verbatim onto the workload — alifecyclepostStart script, anenvvalue — lands underapps/wave-<N>/, and everyapps-wave-<N>Flux Kustomization declarespostBuild.substituteFrom: cluster-vars. Flux runs envsubst over the WHOLE manifest at reconcile time, so an unescaped${VAR:-}meant for the shell is replaced with the empty string before the container ever starts (this silently killed gitea's and nextcloud's OIDC registration for days). Bare$VARand$(cmd)are left alone and need no escaping; a genuine environment knob is declared inclusters/base/cluster-vars.yamland written bare${KNOB}. Full contract:../clusters/base/apps-vms.yaml.render.pyREFUSES to emit a manifest that breaks this rule (Flux's strict substitution mode cannot: it deliberately exempts the${V:-}/${V:=x}/${V:?}default-operator forms).

This is the L0/L1 schema gate (spec docs/14); CI (.gitea/) runs it on every change.
Rendering — render.py (the ServiceDefinition renderer, T-0.3)
render.py compiles a ServiceDefinition into the concrete manifest set defined
by ../schemas/renderer-contract.md: a Namespace (with the
app-namespace/gateway-access labels), the default-deny baseline (R-NET-01), a
Deployment+Service or a KubeVirt VirtualMachine + CDI DataVolume (R-PLAT-02/03), PVCs
(R-STATE), one CiliumNetworkPolicy egress-allow per dependency (R-NET-02), the
egress-class steering label (R-NET-05), HTTPRoute(s) on the shared Gateway (R-TLS/R-DNS),
ServiceMonitor + SLI alerts (R-OBS-01), the Flux ImageRepository/ImagePolicy update plumbing
(R-UPD), and the auth-mode / backup wiring hints (R-IDP/R-STATE-03).

- Deterministic: identical input → byte-identical output (golden-diffable). The L1 render
conformance tests (
conformance/tests/l1-rendering/*) diff the output against committed goldens — run offline byconformance/run.sh --layer l1andci/l1.sh(no cluster). - How CI/Flux consume it: CI invokes
render.pyin the L1 stage; a GitOps flow renders--all catalog -o <rendered-dir>and Flux reconciles the rendered directory. Design choice (renderer-contract is silent on mechanism): a render-then-consume script is the simplest reproducible option — see the header ofrender.py. - Dependency: PyYAML (the renderer's single dependency; the conformance harness stays stdlib-only and only shells out to this script + diffs text).
