jakman85andClaude Opus 5 99560c2d22 feat(auth): declare API paths per service, so --api-route can ship at all
gate / gate (pull_request) Failing after 1m44s
gate / conformance (pull_request) Has been skipped
PR #28 fixed the cookie collision, the 5-minute session and the missing metrics
listener in one renderer function, and deliberately declined `--api-route`
because the config model could not express the difference between two apps.
This adds the hook it was missing and sets the flag only where a measurement
says to.

THE DEFECT. oauth2-proxy answers an unauthenticated request with a 302 to
Keycloak. Its AJAX guard would send 401 instead, but it fires only on an EXACT
`Accept: application/json`, which these apps' JavaScript does not consistently
send. So a browser XHR gets a 302, FOLLOWS IT INVISIBLY, has it satisfied
silently by the live SSO session, and resolves 200 carrying the app's HTML where
the JavaScript expected JSON. On a write it is worse: a browser following a 302
re-issues a POST as a GET and DROPS THE BODY, so the operator's change is
discarded and the UI reports success.

MEASURED, on two apps and two different paths -- which is the whole argument:
  jackett 2026-09-30: 33 x 302 vs 2 x 401 on /api/ paths, and 4 of 6 POSTs
          answered by the proxy and never reaching Jackett (upstream `-`).
  radarr  2026-10-01, 23h after PR #28 deployed (pod radarr-7d55cbffb9-42hmh,
          0 restarts): 232 unauthenticated requests in the pod's whole life and
          ALL 232 are the same call -- POST /signalr/messages/negotiate from a
          browser, 302, upstream `-`. A left-open tab whose session the cookie
          rename orphaned, polling forever, silently redirected every time and
          NEVER re-prompting. The reported symptom, still in production.

So radarr's broken path is /signalr/ and jackett's is /api/, and PIHOLE SERVES
NO /api/ AT ALL. One function renders all five sidecars, so the cheap fix is a
constant -- and a constant applies one app's measurement to four apps nobody
measured. `auth` was `additionalProperties: false`, so there was no per-app
hook. Adding one named, documented key is the change; the block stays closed.

  schemas/servicedefinition.schema.json  1.8.0 -> 1.9.0: optional
      `auth.apiRoutes`, a list (radarr needs two, and --api-route is natively
      repeatable) of anchored path regexes. Plus the shape invariant that a
      non-empty list requires mode: forward-auth, since no sidecar is rendered
      for oidc/native/none and declaring it there would be a SILENT NO-OP.
  catalog/render.py  emits one --api-route per entry, in order, and RAISES on
      an unanchored entry. The flag is SINGULAR -- verified against the pinned
      v7.8.1 binary's own --help; --api-routes does not exist and the proxy
      refuses to start with it.
  catalog/{jackett,radarr}.yaml  the two measured apps.
  catalog/{pihole,sonarr,qbittorrent}.yaml  comments recording that they get
      NOTHING, and why. Sonarr and qBittorrent were measured (0 unauthenticated
      requests in 23h) and left alone: that is evidence of no TRAFFIC, not of no
      need, and sonarr being nearly radarr's codebase is what makes the guess
      tempting and still a guess.
  apps/wave-0/jackett.yaml, apps/wave-1/radarr.yaml  regenerated. Only TWO
      goldens change; pihole/qbittorrent/sonarr are byte-identical to main,
      which is the per-app property proving itself on the real tree.

BREADTH IS THE DANGEROUS DIRECTION AND IT IS NOT SYMMETRIC. A missing
--api-route is a silent 302. A too-broad one answers a plain PAGE LOAD with
401, so a logged-out operator gets a bare error page and is never offered a
sign-in -- the service looks permanently broken. Each entry must therefore
match `^\^/[A-Za-z0-9._~/-]+(\.\*|\$)?$`: anchored at ^/ then literal path
characters. `^/`, `^/.*`, `.*`, `/api/` and `^/api/|^/` are all rejected, all
five provoked. Alternation is refused rather than supported because the flag is
repeatable, so one entry per route costs nothing.

NEW GATE CHECK: conformance/tests/l0-static/oauth2-proxy-api-routes-per-app
(whole-repo scope, so ci/l0.sh's --include-scope union runs it on every
invocation; no bespoke stage, which whole-repo-invariants-wired would fail).
It is a SIBLING of oauth2-proxy-cookie-names-distinct, not an extension of it:
that check's subject is cookie IDENTITY and shares neither inputs nor failure
mode with this, so bundling them would make its name a lie and let a future
api-route decision be expressed only by weakening a COOKIE check.

The check exists for one reason the other gates cannot cover: render-golden
compares the render to the goldens, so a RENDERER CONSTANT plus regenerated
goldens AGREE WITH EACH OTHER while both being wrong. Provoked: the regen exits
0 -- render-golden is happy -- and this check exits 1 with 15 failures naming
pihole, qbittorrent, radarr and sonarr individually. It also asserts the
anchoring pattern is the SAME in the schema and the renderer, because three
surfaces guard this and if they drift the loosest wins silently.

Tested in both directions on throwaway trees outside the repo: compliant tree
rc 0 / 43 assertions / 6 sidecars; pre-change tree rc 1 / 11 failures; and four
targeted mutations (hand-edited golden, widened regex, renderer constant,
deleted schema pattern) each firing their own assertion class and nothing else.

ALSO FOLDED IN (coordinator's request; defect is in the file I own). _selftest()
reached _cookie_name() through a bare `next(genexpr)` with NO default, so
deleting the --cookie-name emission -- the exact mutation that assertion exists
to catch -- raised StopIteration, which escaped _selftest() BEFORE its collected
`SELFTEST FAIL:` lines were printed. Right verdict, zero diagnostics, and it
masked every other assertion the same mutation broke (found by Desmond Oyelaran
while wiring the selftest into the render-golden stage; his PR #33 is not in this
base -- origin/main @ cdf3e14 drives the selftest from no stage, checked). Fixed
with `next(..., None)` plus an explicit check(), so a missing flag reports as a
NAMED assertion. Provoking it exposed three more instances of the same class in
the same block -- `side = fa_containers[1]`, `side["env"][0]`, and the fa_svc
lookup all raise rather than assert when the sidecar is absent -- so all four are
now None-tolerant, and the two fixtures added for --api-route were written that
way from the start. Measured on throwaway copies:
  --cookie-name deleted:  before rc 1 / 0 FAIL lines / StopIteration
                          after  rc 1 / 3 FAIL lines / no traceback
  sidecar not appended:   before rc 1 / 0 FAIL lines / IndexError
                          after  rc 1 / 20 FAIL lines / no traceback
Goldens are unchanged by this part; it touches _selftest() only.

NOT verified, in full in the handoff entry: no browser round-trip by anyone for
this flag -- that a 401 REPAIRS the operator's experience is reasoned from HTTP
semantics, not watched. `^/api/` on radarr is PR #30's measurement of radarr's
pre-fix pod, not mine; the current pod has zero /api/ traffic. Sonarr and
qBittorrent are UNMEASURED, not cleared. --cookie-refresh is still unexercised
(0 AuthSuccess on all five pods). Nothing was applied; the live pods are still
the pre-change spec.

jakman85andClaude Opus 5 5da116b34d fix(oauth2-proxy): platform-admins may reach the media UIs — the immediate 403
The four forward-auth media UIs (jackett, qbittorrent, radarr, sonarr) gate on
`--allowed-group=media-users` alone. On prod the `homelab` realm has exactly one
user — the operator's `jakman85` — and it is a member of `platform-admins` ONLY.
`media-users` has zero members, so those four hosts were reachable by nobody:
oauth2-proxy completed OIDC discovery, redirected to Keycloak, got a token whose
`groups` claim is `["platform-admins"]`, found no allowed group in it, and
answered 403. No login form appeared because the browser already held a Keycloak
SSO session from a platform-admins login — hence "403 immediately".

pihole and crafty were unaffected: they already gate on platform-admins.

`--allowed-group` is repeatable and OR-ed, so listing both groups means "media
consumers OR platform operators". This grants no real privilege — platform-admins
already maps to cluster-admin via k8s-oidc-rbac.yaml (oidc:platform-admins), so a
member can already exec into these pods — and it keeps media-users meaningful for
non-admin household accounts.

Ruled out while diagnosing: client-secret drift (all 7 sidecar secrets hash-match
keycloak-realm-clients), stale apex URLs (every live sidecar carries
keycloak.prod.home.keithjackson.dev), missing group mappers (all 7 clients emit
claim=groups, full.path=false), and the central oauth2-proxy pod restarts — those
were Keycloak returning 503 "no healthy upstream" to OIDC discovery at startup, a
consequence of the Keycloak roll, not a cause.

Goldens re-rendered with the canonical command:
  python3 catalog/render.py --all catalog -o apps --wave-layout --no-image-automation

jakman85andClaude Opus 5 6b953cc56b fix(arrs): the config PVC was mounted where the app never looks
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
sonarr, radarr, jackett and qbittorrent all mounted their Longhorn config PVC at
the renderer's default /data/config, but every one of these images runs with
`-data=/config`. So the PVC held nothing but lost+found while the app wrote its
entire configuration to the container's EPHEMERAL writable layer — destroyed on
every pod recreation: restart, reschedule, image bump.

Measured in-cluster before fixing, per app, rather than inferred:
  /data/config  dev=2080  [lost+found]                      <- the Longhorn PVC
  /config       dev=2053  [Sentry asp config.xml logs ...]   <- the node's own disk
and a marker file written to /config did not appear in /data/config, so they are
demonstrably different storage. qbittorrent's /config sat on dev=66309
(/dev/nvme0n1p5), i.e. whichever node it happened to land on.

This is the SAME failure catalog/plex.yaml:54 already records having fixed for
Plex; plex was the only one of the five that was right.

The live /config contents were copied onto each PVC BEFORE this landed, so
jackett's API key and qbittorrent's credentials — which other apps reference —
survive the move rather than being regenerated.

catalog/sonarr.yaml:61 documented this as a latent bug and deliberately left it
because it changes live on-disk state. It is being fixed now because all four pods
had just been recreated, so their configs were freshly generated and nothing had
accumulated to lose.

jakman85andClaude Opus 5 82aff4d053 feat(apps): attach the media library and the legacy Nextcloud dataset over NFS
plex, sonarr, radarr and nextcloud each gain one bulk volume. Authored in the catalog and
re-rendered, never hand-edited into apps/ (render-golden: 10/10). Layout, the export change the
operator must apply, the uid analysis and the validation probes are in docs/BULK-NFS-STORAGE.md;
everything there was measured on the host over read-only SSH, not assumed.

WHAT THE LAYOUT TURNED OUT TO BE, AND WHY IT DECIDED THE DESIGN
/mnt/Storage/plex holds movies/ tv/ photos/ AND downloads/ as SIBLINGS in one dataset — so the
arrs' import source and their libraries are one filesystem on the server, and the download client's
completed folders are already named radarr/ and tv-sonarr/. The k3s arrs are joining a tree an arr
stack has been driving for a long time.

That sibling fact is the whole argument for the arrs mounting the export ROOT rather than a
subPath per directory. Sonarr and Radarr import by hardlinking or atomically renaming, both
same-filesystem operations, and to the kernel "same filesystem" means SAME MOUNT. Two subPath
mounts of one export are two mounts: link() across them returns EXDEV regardless of what the
server knows, and the arrs do not fail loudly — they degrade to copy-then-delete, rewriting every
file over NFS and destroying the seeding copy. The smallest subtree containing both tv/ and
downloads/ IS the export root, so the root mount is the MINIMAL mount that preserves hardlinks.
Least privilege bounded below by a hard requirement. The cost is stated, not hidden: sonarr can
also write /media/movies.

  plex       /mnt/Storage/plex      -> /media                 ro   ReadOnlyMany
  sonarr     /mnt/Storage/plex      -> /media                 rw   ReadWriteMany
  radarr     /mnt/Storage/plex      -> /media                 rw   ReadWriteMany
  nextcloud  /mnt/Storage/nextcloud -> /mnt/legacy-nextcloud  ro   ReadOnlyMany  (subPath: nextcloud)

Plex is read-only because it indexes and streams; every write on that tree belongs to the arrs, and
saying so removes Plex from the set of things that can damage 8.33 T. All three media consumers use
the SAME mountPath deliberately: when qbittorrent is eventually given this export, the arrs and the
download client will already agree on absolute paths, which is the other precondition for hardlinked
imports.

*** /media AND NOT /data — A COLLISION CAUGHT WHILE RENDERING. *** The arrs' Longhorn config PVC
renders at the renderer default /data/config. A media mount at /data is mounted OVER it and MASKS
the config volume: the pod comes up with its app database shadowed by an 8 T media tree. That
discovery also exposed a SEPARATE PRE-EXISTING BUG, reported and deliberately NOT fixed here:
LinuxServer arr images run with -data=/config, so /data/config is very likely the wrong home for
that PVC and the app has been writing its EPHEMERAL layer — the exact failure catalog/plex.yaml's
mountPath comment records already having been bitten by. Plex was fixed; sonarr, radarr, qbittorrent
and jackett were not. Fixing it starts those apps from an empty config volume, so it needs its own
change with the operator present. This change does not make it worse.

UID/GID — THE FAILURE THIS TIER ALWAYS HAS
The export is sec=sys + no_root_squash, so the client's numeric uid passes through verbatim and the
server's ownership is the entire access story. The tree is 0755 owned 1000:3000, so ONLY uid 1000
can write it. LinuxServer images default to 911. Without intervention sonarr and radarr would have
mounted cleanly, gone Ready, and failed EVERY import with EACCES.

And fsGroup cannot fix that — the in-tree NFS plugin does NO ownership management, so
podSecurityContext.fsGroup is a no-op on an NFS volume. Reaching for it is how this gets
misdiagnosed. So PUID=1000/PGID=3000 are added to both arrs (PGID 3000 keeps what they write
group-readable to the live non-k3s consumers of the same export), and fsGroup: 3000 is added for
the LONGHORN config PVC only, so changing PUID does not depend on the image re-chowning /config.
plex already runs as 1000 and reads a 0755 tree; nextcloud reads as www-data. Neither needs work.

NEXTCLOUD IS MOUNTED READ-ONLY, WHICH IS A DEVIATION FROM THE BRIEF — ON EVIDENCE
The task said nextcloud writes. The dataset says otherwise: of 270 G, 267 G is config_backup/, the
rest is config/ (103 M) and config_old/ (3.4 G). There is NO data/ directory. This is the OLD
non-k3s instance's configuration plus a backup blob — an archive — and that instance is STILL LIVE
on it (exported rw to 192.168.1.6 and .5, which the operator has said must stay active). Two
Nextclouds writing one instance's config directory, each with its own database and therefore its own
oc_filecache, is unrecoverable corruption. "Do not grant more than needed" lands on ro, and ro is
the trivially reversible choice. If the intent is in fact a MIGRATION, that is a larger and more
deliberate change than a mount; the one-line flip is documented.

Read-only for nextcloud can additionally be enforced SERVER-side (only nextcloud consumes that
dataset from k3s), and the sharenfs value in the doc uses ro= for the k3s clients. The media tree
cannot: plex and the arrs may land on any node, so the server sees the same addresses for reader
and writers. Plex's ro is therefore a client-side guarantee — stated as a limitation, not left
implied.

jakman85andClaude Opus 5 c8c1d2935d feat(dns): per-environment BASE_DOMAIN — prod moves to its own subdomain
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
INCIDENT FIX. Prod's external-dns DELETED EVERY ONE OF DEV'S PUBLIC DNS RECORDS. Both
clusters ran policy: sync against the SAME Cloudflare zone with the SAME implicit
txtOwnerId (`default`), so prod believed it owned dev's records, found no matching sources,
and removed them plus their TXT registry entries. Dev recovered ~30s after prod was scaled
to 0; verified restored against Cloudflare directly (my first check went through a pfSense
override and falsely showed healthy — local resolvers are not evidence about public DNS).

THE MISS WAS MINE, and it was a failure of imagination in how I briefed every agent. I put
"never touch dev" in brief after brief and enforced it — separate kubeconfigs, verified
--limit, sha-checked dev's kubeconfig before and after. Every one of those guards held. NONE
of them covered SHARED EXTERNAL RESOURCES. Prod reconciling its OWN correctly-authored
manifests reached across a third party and destroyed dev's state. Cluster-to-cluster
isolation was verified; the dependency that mattered was cluster-to-Cloudflare.

Operator's architecture: dev -> *.dev.home.keithjackson.dev, prod ->
*.prod.home.keithjackson.dev, apex CNAME <svc>.home -> <svc>.prod.home.

PHASE 1 ONLY (this commit): prod moves to its own subdomain. DEV IS NOT MIGRATED and its
effective hostname stays home.keithjackson.dev, so dev renders byte-identically and nothing
live moves. That alone ends the collision and unblocks prod. Phase 2 (dev -> dev.home. +
apex CNAMEs) is deferred to when the operator is present: it relocates Keycloak's issuer and
12 clients' redirect URIs, forces a rolling k3s restart and kubectl SSO re-issue for every
user, and moves gitea.home. — which is BOTH the GitOps source and the current push target.

BASE_DOMAIN WAS A DEAD KNOB — it existed in cluster-vars but the status report flagged it as
referenced by nothing, because hostnames were hardcoded throughout. Now real: 141 refs.
Searched the AUTHORITATIVE reconciled set by resolving each Flux spec.path transitively via
conformance/lib/status.py — the same resolver the L0 gate uses, so "what Flux reconciles"
has one definition. 185 occurrences across 47 files in 154 reconciled files. Tokenized:
Gateway listeners, the wildcard Certificate, coredns-custom, external-dns, Keycloak
instance/realm (26 redirect URIs), oauth2-proxy, Grafana OIDC, all HTTPRoutes, Homepage's 15
links, 30 runbook_urls, unifi cloud-init, render.py's ZONE constant (which drove
--oidc-issuer-url/--cookie-domain/--whitelist-domain on every forward-auth sidecar) and 11
catalog/ ServiceDefinitions re-rendered canonically. Left alone: 43 comment/prose
occurrences and non-reconciled paths.

TWO THAT CANNOT BE TOKENIZED, flagged not forced:
  - headlamp's OIDC URLs live inside a SOPS-encrypted Secret; re-encrypting rewrites the MAC
    over every value and the OFFLINE harness cannot verify it (kustomize does not decrypt),
    so an error would break live-dev SSO with no pre-flight proof. Prod needs its own copy
    anyway — client secrets are realm-scoped.
  - kube-apiserver --oidc-issuer-url is a k3s SERVER FLAG, not a manifest, so Flux can never
    reach it. Done on the inventory seam instead (k3s_base_domain -> k3s_oidc_issuer_url,
    overridden in group_vars/k3s_prod). Verified per host: dev keeps the default, prod gets
    prod.home.

EXTERNAL-DNS OWNER, the actual incident cause: txtOwnerId is now explicit per environment —
dev renders exactly `default` (the chart default it was already using, so its existing
records stay recognised) and prod gets `prod`. The BASE default is a NON-COLLIDING SENTINEL,
deliberately not `default`, so a future environment that forgets the knob owns nothing and
can delete nothing rather than silently inheriting dev's identity.

I OVERRODE ONE AGENT DECISION against our own prior finding: it narrowed prod's
domainFilters to prod.home.keithjackson.dev as defence in depth. FINDING F-DNS1
(DECISIONS-LOG 2026-08-17) already proved a subdomain filter DROPS THE PARENT ZONE —
ExternalDNS generates the record then skips it with "no hosted zone matching record DNS
Name". Prod would have published NOTHING. Set to the ZONE (keithjackson.dev) like dev.
Isolation comes from the subdomain split plus txtOwnerId, which is what the incident
actually needed and what a domain filter cannot provide.

DEV PROVEN UNCHANGED: 11 of 12 substituting paths byte-identical; the 12th differs by
exactly one line, `+ txtOwnerId: default` — the value dev was already using implicitly.
POSITIVE CONTROLS confirm the harness is not blind: perturbing BASE_DOMAIN moves 10 of 12
hashes (the 2 that don't provably contain no hostname), perturbing the owner id moves
exactly 1. Prod's rendered output has ZERO home.keithjackson.dev references outside prod.,
and its cert renders *.prod.home.keithjackson.dev — no overlap with dev's.

L0 substitution assertions 106 -> 254; BASE_DOMAIN is no longer flagged dead. Gate PASS.

PROD REMAINS SUSPENDED (platform + 10 downstream tiers) pending review; nothing applied.

Serves: R-ENV-02, R-DNS-01, R-DNS-02, R-DNS-03, R-TLS-01.
