fix(unifi): the installer secret was committed unencrypted

Every other *.sops.yaml in this repo carries sops metadata and ENC[] values; this one shipped with neither and both fields as literal REPLACE-ME. Two consequences: 'sops <file>' fails with 'sops metadata not found', so the documented operator step could not work; and Flux would pass the file through undecrypted and create the Secret with the literal placeholder strings. Encrypted in place with the repo's age recipient, placeholders intact. Round-trip verified: sops -d returns installer-url and console-password as REPLACE-ME, so the operator's workflow is now the normal one — sops the file, set both values, commit. Both fields need setting, not just the password: installer-url is also REPLACE-ME, which I had omitted from the operator instructions. Co-Authored-By: Claude Opus 5 <[email protected]>

+# RECOVERY BASELINE — the COMPLETE Cloudflare record set for zone `keithjackson.dev`
+# as it stood IMMEDIATELY BEFORE feat/externaldns-scope-public-only is applied.
+#
+# WHY THIS FILE EXISTS. The branch that adds it changes which resources ExternalDNS considers,
+# and ExternalDNS runs `policy: sync` — a record whose source stops matching is DELETED, not
+# merely left alone. That is a one-way, outward-facing operation against a live authoritative
+# zone, so the pre-state is captured and committed BEFORE the change lands, and any record the
+# reconcile removes can be restored by hand from this file. It is the same discipline as
+# dns-before.txt / dns-verify.txt / dns-post-l2.txt beside it, applied to a destructive-capable
+# change rather than to a migration.
+#
+# CAPTURED 2026-09-14 from the Cloudflare API (GET /zones/<id>/dns_records, all pages) using the
+# SOPS-encrypted token in platform/externaldns/cloudflare-api-token.sops.yaml. Read at the
+# AUTHORITY, not through a resolver: 1.1.1.1 served stale answers for minutes after the
+# 2026-09-13 apex flip and must not be trusted for this. `dig` is on the host but NOT in the
+# devcontainer, which has previously produced false "no records" readings — the API is the only
+# reading that is both complete and authoritative.
+#
+# FORMAT (5 fields, `|`-separated) — wider than the sibling files on purpose: a restore needs the
+# TTL and the proxy flag, not just the value.
+#
+#   <type>|<name>|<content>|<ttl>|<proxied>
+#
+# ttl 1 = Cloudflare "Automatic". proxied false = DNS-only (grey cloud), which every record here
+# is; a restore that flips one to proxied would put Cloudflare's edge in front of a LAN address.
+#
+# 39 records. 36 of them are ExternalDNS-managed (18 A + their 18 `a-`-prefixed TXT registry
+# entries), every one registered `external-dns/owner=prod` — i.e. THIS cluster owns them, which
+# is why this cluster's reconcile is able to delete them. The remaining 3 belong to the legacy
+# non-k3s stack and carry NO TXT registry entry, so no owner id claims them and ExternalDNS
+# cannot touch them regardless of what this branch does:
+#
+#   *.keithjackson.dev            -> 136.51.115.252   legacy stack (the zone wildcard)
+#   brickbreak.keithjackson.dev   -> 20.236.242.14    unrelated, off-prem
+#   dev.brickbreak…               -> 20.236.242.14    unrelated, off-prem
+#
+# NOTE there is NO `*.home.keithjackson.dev` wildcard in the zone any more (the comment in
+# clusters/prod/kustomization.yaml still says the zone has both wildcards; it does not, as of
+# this capture). A single-label wildcard does not match two labels, so `*.keithjackson.dev` does
+# NOT cover `<svc>.home.keithjackson.dev`: when a specific `<svc>.home` record is removed, that
+# name goes to NXDOMAIN publicly rather than falling back to the legacy IP. That is the intended
+# end state for `internal` services and it is also precisely why Pi-hole must already be
+# answering the LAN authoritatively before this branch merges.
+#
+# WHICH OF THESE THIS BRANCH DELETES — the 12 rows for the six `exposure: internal` catalog
+# services (jackett, pihole, qbittorrent, radarr, semaphore, sonarr): each one's A record and its
+# `a-`-prefixed TXT registry entry. Nothing else. Verified live on prod against the deployed
+# v0.21.0 with a throwaway hostname before any of this was authored: adding the annotation to an
+# HTTPRoute that already had a published record produced
+# `action=DELETE record=... type=A` and `action=DELETE record=a-... type=TXT` one reconcile
+# interval (~60s) later, and nothing else in the zone moved.
+#
+# TO RESTORE ONE ROW BY HAND (both halves, or ExternalDNS will not recognise the record as its
+# own): recreate the A record with its value/ttl/proxied from this file, then recreate the
+# matching `a-<name>` TXT with its content VERBATIM — the `heritage=…,external-dns/owner=prod,
+# external-dns/resource=…` string is what re-establishes ownership. An A record restored without
+# its TXT is unowned and will not be reconciled; a TXT restored with a wrong `resource=` value
+# points the registry at a source object that does not exist.

+
+    `internal` renders NO public DNS record. That sentence was in the contract from the start and
+    nothing enforced it: ExternalDNS watched EVERY HTTPRoute the shared Gateway carried, so an
+    `internal` service's route published `<name>.${BASE_DOMAIN}` into the PUBLIC authoritative
+    Cloudflare zone, answering with the Gateway VIP — an RFC1918 address. Six of them did
+    (jackett, pihole, qbittorrent, radarr, semaphore, sonarr), which published the internal
+    subnet, the Gateway VIP and a full service inventory to anyone who asked, and made every one
+    of those names a DNS-rebind primitive that the SOHO router strips on the way back in.
+
+    THE MECHANISM, verified against the DEPLOYED version (chart >=1.21.0 <1.22.0, app v0.21.0 —
+    `registry.k8s.io/external-dns/external-dns:v0.21.0`, read off the live prod Deployment), not
+    from memory. external-dns v0.21.0 `source/annotations/processors.go`:
+
+        func IsControllerMismatch(entity metav1.ObjectMetaAccessor, rType string) bool {
+            value, ok := entity.GetObjectMeta().GetAnnotations()[ControllerKey]
+            if ok && value != ControllerValue { ...; return true }
+            return false
+        }
+
+    with `ControllerKey = "external-dns.alpha.kubernetes.io/controller"` and
+    `ControllerValue = "dns-controller"`. `source/gateway.go` calls it per route inside
+    `Endpoints()`, BEFORE any hostname is resolved:
+
+        if annotations.IsControllerMismatch(meta, src.rtKind) { continue }
+
+    so an HTTPRoute carrying any other value is not merely unpublished — it never becomes an
+    endpoint at all, for any hostname it names. `source/service.go` applies the identical check,
+    so the same annotation scopes the `service` source too if a rendered Service ever grows an
+    external-dns hostname.
+
+    WHY THIS IS STRUCTURAL AND NOT INCIDENTAL. The annotation is derived HERE, from `exposure`,
+    with no per-service list anywhere: every HTTPRoute this renderer emits for an `internal`
+    service carries it, and ci/render-golden.sh proves `apps/` reproduces byte-for-byte from
+    `catalog/`, so an `internal` service cannot EXIST in the applied tree without it. Flipping
+    `exposure: internal` to `public` is the only edit that can publish a name, which is exactly
+    the operator-facing declaration R-DNS-03 is written in terms of. The L0 check
+    conformance/tests/l0-static/internal-services-publish-no-public-dns re-proves all of that on
+    every gate run, including that this function reads `exposure` rather than naming services.
+
+    WHY NOT A CLUSTER-WIDE OPT-IN FILTER (`--label-filter`, chart `labelFilter`). It exists, and
+    v0.21.0's own `--help` names both sources in use as supporting it ("currently supported by
+    source types crd, gateway-httproute, ... service and ambassador-host"), so a "publish only
+    what is labelled" posture is available and is STRONGER by default. It is not taken here
+    because its blast radius is not this defect's: seven published names come from hand-authored
+    platform/apps manifests that carry no `exposure` field and that this renderer never sees
+    (auth/oauth2-proxy, crafty + crafty-mc, grafana, headlamp, the homepage apex, unifi). An
+    opt-in filter DELETES all seven the moment it is set, and whether each should stay published
+    is an operator decision, not a renderer one. Per-resource exclusion has exactly the blast
+    radius of the reported defect. The filter remains the available hardening once those seven
+    are adjudicated — see platform/externaldns/helmrelease.yaml.

+# L0 STATIC — no service declared `internal` can produce a PUBLIC DNS record
+# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
+#
+# THE DEFECT THIS CLOSES. docs/09 R-DNS-03 says `internal` services are unreachable from the
+# public internet, that external names resolve to the PUBLIC IP, and that Pi-hole provides the
+# internal split-horizon answers. schemas/renderer-contract.md §exposure says an `internal`
+# service renders "no public DNS record". NOTHING ENFORCED EITHER SENTENCE. ExternalDNS
+# (platform/externaldns/helmrelease.yaml, `sources: [gateway-httproute, service]`,
+# `policy: sync`, provider cloudflare) considered EVERY HTTPRoute on the shared Gateway, so six
+# `exposure: internal` services — jackett, pihole, qbittorrent, radarr, semaphore, sonarr — each
+# published `<name>.home.keithjackson.dev` into the PUBLIC authoritative Cloudflare zone,
+# answering with the Gateway VIP 192.168.2.20. Verified at the authority on 2026-09-14; the
+# pre-state is committed at .standup-dns/dns-20260914-pre-externaldns-scope.txt.
+#
+# Three things were wrong at once, and none of them was visible from inside the cluster:
+#   * the internal subnet, the Gateway VIP and a complete service inventory were publicly
+#     enumerable by anyone who could guess or brute-force a label;
+#   * a public name answering with an RFC1918 address IS a DNS-rebind primitive, which is why the
+#     SOHO router at 192.168.2.1 strips those answers and LAN clients need per-client dnsmasq
+#     overrides to reach their own services;
+#   * the guarantee was only ever prose. `exposure` was the operator's one declaration of intent
+#     and it had NO effect on DNS whatsoever, so "internal" meant nothing an attacker had to
+#     respect.
+#
+# WHY THE FIX NEEDS A GUARD AND NOT JUST A COMMIT. The mechanism is an annotation on a rendered
+# HTTPRoute. An annotation is exactly the kind of thing that survives review by looking harmless
+# and then disappears in a refactor of `_route_meta`, a hand-edit of apps/, or a new service added
+# by copying a public one. Nothing about its ABSENCE is loud: the service keeps working on the LAN,
+# the Kustomization stays Ready, and the only symptom is a public record nobody is looking at. The
+# 2026-09-13 ServiceMonitor incident in this same tree is the precedent — twelve monitors pointed
+# at a port that did not exist for weeks, silently, because the only thing asserting the wiring was
+# prose. This test makes the DNS guarantee a gate condition instead.
+#
+# GIVEN every ServiceDefinition in catalog/ and every HTTPRoute and external-dns-annotated
+#       Service this repo authors,
+# WHEN  each catalog service's rendered routes are resolved in the applied tree (apps/),
+# THEN  (1) every route of an `exposure: internal` service carries ExternalDNS's own controller
+#           annotation set to something OTHER than `dns-controller`, which external-dns v0.21.0
+#           uses to skip the source object outright (source/gateway.go ->
+#           annotations.IsControllerMismatch, checked before any hostname is resolved), so the
+#           route cannot become an endpoint for ANY name it declares;
+#       (2) NO route of an `exposure: public` service carries it — asserted explicitly, because a
+#           renderer that stamped every route would satisfy (1) perfectly while silently
+#           withdrawing the five public services' records, and `policy: sync` would delete them;
+#       (3) the same holds for the `service` source: an internal service's rendered Service may
+#           not carry an external-dns hostname annotation without the disown annotation beside it.
+#           Two sources are configured, so closing only the route half is half a guarantee;
+#       (4) the annotation is DERIVED FROM `exposure` in catalog/render.py and from nothing else —
+#           the emitting function must read `exposure`, must not name any catalog service, and
+#           must not be able to emit external-dns's own `dns-controller` value (the one value that
+#           CLAIMS a route rather than releasing it, inverting the guarantee while looking
+#           plausible). A per-service list is how twelve ServiceMonitors acquired one identical
+#           wrong port name in a single edit;
+#       (5) THE RENDERER IS PROVEN END-TO-END on synthetic ServiceDefinitions, by invoking the
+#           SHIPPED catalog/render.py as a subprocess: an `internal` fixture must yield the
+#           annotation, a `public` fixture must not, and a fixture that OMITS `exposure` must also
+#           yield it (the contract's default posture is `internal`, and omitting the field is the
+#           likeliest way a new service arrives). Without this the check would still pass if the
+#           renderer stopped working and someone hand-maintained apps/;
+#       (6) every HTTPRoute or annotated Service in the tree that the catalog does NOT render is
+#           DECLARED in KNOWN_NON_CATALOG_PUBLISHERS with what it publishes and why it is out of
+#           scope. Those are hand-authored platform/apps manifests with no `exposure` field for a
+#           renderer to read, and they are the seven names that REMAIN publicly advertised with an
+#           RFC1918 answer after this change. The register is shrink-only: an entry that stops
+#           matching a real object FAILS as stale, so the set of unadjudicated publishers cannot
+#           quietly grow, and adding a new one is a review event;
+#   AND (7) the check is LOAD-BEARING: this Test DECLARES `conformance.home.k3s/scope: whole-repo`,
+#           so ci/l0.sh Stage 3b's `--include-scope whole-repo` unions it into EVERY gate run, and
+#           ci/gate.sh blocks the merge when the l0 stage fails. It deliberately adds NO stage to
+#           ci/l0.sh — tests/l0-static/whole-repo-invariants-wired fails the gate if anyone does.
+#
+# WHY SCOPE, NOT REQUIREMENTS: ci/touched-requirements.sh's path map keys apps/* to NOTHING, and
+# apps/ is exactly where the rendered routes live. A requirement-scoped selection would therefore
+# filter this check out of the change most likely to break it — a hand-edit of a rendered route.
+# Same reasoning as its whole-repo siblings.
+#
+# STATUS: EXECUTABLE. `check.sh` is an offline assertion script (PyYAML, as catalog/render.py and
+# the sibling l0-static checks use); conformance/run.sh --layer l0 and ci/l0.sh run it directly,
+# and this Chainsaw Test wraps the SAME script.
+#
+# NOT proven (honest gaps; this is static, and it runs with no cluster and no network):
+#   - That the record is actually GONE from Cloudflare. That is a live read against an external
+#     authority and belongs in L2 beside conformance/tests/l2-behavioral/dns-exposure, which owns
+#     the positive direction (a public name DOES appear). The negative direction was proven
+#     MANUALLY on prod against the deployed v0.21.0 before this landed — a throwaway HTTPRoute
+#     carrying the annotation produced no record at all, and adding the annotation to a route that
+#     already had one produced `action=DELETE` for both its A record and its `a-` TXT registry
+#     entry within one ~60s reconcile — but a manual proof is not a gate.
+#   - That an `internal` name is unreachable from the internet. No DNS record is necessary for
+#     reachability; a port-forward plus a hardcoded IP still reaches the Gateway. This check owns
+#     the NAME axis only. R-NET-04 / the edge port-forward posture owns the other.
+#   - Anything about the seven non-catalog publishers' own correctness. The register records WHAT
+#     each publishes so the claim is reviewable, which is all a static check can offer.
+#   - Anything about the five `public` services' TARGET. They still resolve to the Gateway VIP
+#     rather than a routable address; that is an open operator decision recorded in
+#     platform/externaldns/helmrelease.yaml, and asserting a target here would hard-code a guess.

+# See chainsaw-test.yaml's header for the full WHY. In one paragraph:
+#
+# docs/09 R-DNS-03 and schemas/renderer-contract.md §exposure both say an `internal` service
+# renders no public DNS record. Nothing enforced it: ExternalDNS watched every HTTPRoute on the
+# shared Gateway, so six internal services published `<name>.home.keithjackson.dev` into the
+# public Cloudflare zone answering with the RFC1918 Gateway VIP (verified at the authority
+# 2026-09-14; pre-state committed at .standup-dns/dns-20260914-pre-externaldns-scope.txt). The fix
+# derives ExternalDNS's controller annotation from `exposure` in catalog/render.py; this check is
+# what keeps it derived, present, and scoped.
+#
+# ASSERTIONS
+#   (0) the inventory is non-empty and the parse contract holds (anti-vacuous-pass);
+#   (1) every rendered route of an `internal` service carries the disown annotation;
+#   (2) NO rendered route of a `public` service carries it — a renderer stamping everything would
+#       satisfy (1) and silently delete the five public records under policy: sync;
+#   (3) the `service` source half: an internal service's Service may not carry an external-dns
+#       hostname annotation without the disown annotation beside it;
+#   (4) catalog/render.py DERIVES the annotation from `exposure` — the emitting function reads that
+#       field, names no catalog service, and cannot emit external-dns's own `dns-controller`;
+#   (5) the SHIPPED renderer is proven end-to-end on synthetic ServiceDefinitions (internal,
+#       public, and `exposure` OMITTED — the contract's default posture is internal);
+#   (6) every HTTPRoute / annotated Service the catalog does NOT render is declared in
+#       KNOWN_NON_CATALOG_PUBLISHERS — shrink-only, stale entries FAIL;
+#   (7) the check is LOAD-BEARING: whole-repo scope declared in chainsaw-test.yaml, honoured by
+#       ci/l0.sh's --include-scope union, and ci/gate.sh blocks on an l0 failure. NO hand-written
+#       ci/l0.sh stage (whole-repo-invariants-wired fails the gate if one appears).
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — it is STATIC, offline, cluster-free):
+#   - That the record is gone from Cloudflare. Live read; belongs beside
+#     conformance/tests/l2-behavioral/dns-exposure, which owns the positive direction. The negative
+#     direction was proven manually on prod against the deployed v0.21.0 (a route carrying the
+#     annotation produced no record; adding it to a route that had one produced action=DELETE for
+#     both the A and its `a-` TXT within ~60s) — but a manual proof is not a gate.
+#   - That an internal name is UNREACHABLE. A port-forward plus a literal IP needs no DNS record.
+#     This check owns the NAME axis only.

+    #
+    # THE DEFECT. `sources` above admits EVERY HTTPRoute on the shared Gateway, and each one's
+    # address is the Gateway VIP. docs/09 R-DNS-03 says `internal` services are unreachable from the
+    # public internet and that Pi-hole serves the internal split-horizon answers; the renderer
+    # contract said an `internal` service renders "no public DNS record". Neither sentence was
+    # enforced by anything, so six `exposure: internal` services (jackett, pihole, qbittorrent,
+    # radarr, semaphore, sonarr) published `<name>.home.keithjackson.dev` into this PUBLIC
+    # authoritative zone answering 192.168.2.20. That exposed the internal subnet, the Gateway VIP
+    # and a complete service inventory to anyone who could guess a label, and made every one of
+    # those names a DNS-rebind primitive — which is exactly why the SOHO router at 192.168.2.1
+    # strips RFC1918 answers and LAN clients need per-client dnsmasq overrides to reach their own
+    # services. Pre-state captured at the AUTHORITY and committed:
+    # .standup-dns/dns-20260914-pre-externaldns-scope.txt.
+    #
+    # THE MECHANISM — per-resource exclusion, emitted by catalog/render.py from `exposure`.
+    # An `internal` service's rendered HTTPRoute carries
+    #     external-dns.alpha.kubernetes.io/controller: none
+    # ExternalDNS v0.21.0 (the DEPLOYED app version; read off the live prod Deployment, image
+    # registry.k8s.io/external-dns/external-dns:v0.21.0) skips any source object whose `controller`
+    # annotation is present and != its own `dns-controller`:
+    #     source/annotations/processors.go  IsControllerMismatch()
+    #     source/gateway.go  Endpoints():  if annotations.IsControllerMismatch(meta, src.rtKind) { continue }
+    #     source/service.go  Endpoints():  the identical check
+    # The gateway check runs BEFORE any hostname is resolved, so such a route cannot become an
+    # endpoint for any name it declares. PROVEN LIVE on prod before this landed, with a throwaway
+    # hostname and no existing record at risk: an annotated route published nothing at all, and
+    # ADDING the annotation to a route that already had a record produced
+    #   action=DELETE record=<name> type=A    and   action=DELETE record=a-<name> type=TXT
+    # one ~60s reconcile later, and moved nothing else in the zone.
+    #
+    # WHY PER-RESOURCE AND NOT A CLUSTER-WIDE OPT-IN FILTER. The chart's `labelFilter`
+    # (--label-filter) is the stronger default posture — publish only what is labelled — and
+    # v0.21.0's own --help confirms BOTH configured sources support it ("currently supported by
+    # source types crd, gateway-httproute, ... service and ambassador-host"). It is NOT set here
+    # because its blast radius is not this defect's. Nine publishing objects in this repo are
+    # hand-authored platform/apps manifests with no `exposure` field for the renderer to read, and
+    # seven of them hold live records: auth (oauth2-proxy), crafty, crafty-mc, grafana, headlamp,
+    # the apex (homepage), unifi. Setting an opt-in filter DELETES all seven on the next reconcile,
+    # and whether each should be publicly resolvable at all is an OPERATOR decision per name, not a
+    # renderer one. They are enumerated in the shrink-only register in
+    # conformance/tests/l0-static/internal-services-publish-no-public-dns/check.sh, so the set
+    # cannot grow silently — adjudicate them there, then this filter becomes the right hardening.
+    #
+    # DELIBERATELY UNTOUCHED: `policy: sync`, `txtOwnerId`, `domainFilters`. Nothing above widens
+    # what this instance can see or own; per-resource exclusion only ever REMOVES an object from
+    # this instance's view, so it cannot make prod capable of deleting a record it does not own.
+    # ---------------------------------------------------------------------------------------------
+    # THE PUBLIC-TARGET GAP — STILL OPEN, AND NOT FIXABLE HERE ON v0.21.0 (operator decision)
+    #
+    # The five `exposure: public` services (plex, gitea, seerr, keycloak, nextcloud) publish records
+    # that point at 192.168.2.20 — the Gateway VIP, an unroutable RFC1918 address — so they are not
+    # actually reachable from the internet either. Their records are LEFT EXACTLY AS THEY ARE by
+    # this change, for two independent reasons:
+    #
+    #   1. THE VALUE IS NOT ESTABLISHED. The one public IP this repo knows is 136.51.115.252
+    #      (clusters/prod/kustomization.yaml, where the zone's `*.keithjackson.dev` wildcard also
+    #      points). It belongs to the LEGACY non-k3s stack and currently serves a placeholder
+    #      certificate. Whether prod's public services belong behind it, behind a new forward, or
+    #      are not meant to be public at all is an operator decision. Breaking five services' DNS
+    #      on a guess is worse than leaving a known-wrong-but-stable state.
+    #   2. THE MECHANISM CANNOT BE SCOPED TO THEM. `external-dns.alpha.kubernetes.io/target` is a
+    #      real override, but in v0.21.0's gateway-httproute source it is read ONLY from the
+    #      GATEWAY (source/gateway.go: `overrides: annotations.TargetsFromTargetAnnotation(
+    #      gw.Annotations)`) and from a ListenerSet listener — NEVER from the HTTPRoute. So there is
+    #      no per-service target override while every public service shares the `shared` Gateway.
+    #      Annotating the Gateway would move EVERY gateway-sourced record, which after this change
+    #      still includes auth, crafty, grafana, headlamp and the apex — i.e. it would publish a
+    #      routable address for admin UIs. That is strictly worse than the status quo.

 - `internal` renders **no public DNS record** and is never port-forwarded (PiHole resolves it to the
  internal Gateway VIP).
+- **HOW "no public DNS record" IS MADE TRUE, since it was prose only until 2026-09-14.** Every
+  HTTPRoute rendered for an `internal` service carries ExternalDNS's own controller annotation with
+  a value other than the one ExternalDNS claims:
+
+      external-dns.alpha.kubernetes.io/controller: none
+
+  ExternalDNS v0.21.0 (`source/annotations/processors.go`) skips any source object whose
+  `controller` annotation is present and `!= "dns-controller"`, and `source/gateway.go` applies that
+  check **inside `Endpoints()` before any hostname is resolved** — so the route never becomes an
+  endpoint for any name it declares. `source/service.go` applies the identical check, which covers
+  the second configured source. It is derived **from `exposure` and nothing else**
+  (`catalog/render.py` `_externaldns_route_annotations`), so the operator's one declaration decides,
+  a service that OMITS `exposure` inherits the `internal` default and is likewise unpublishable, and
+  there is no per-service list to forget to extend. `ci/render-golden.sh` proves `apps/` reproduces
+  from `catalog/`, so an `internal` service cannot exist in the applied tree without it, and
+  `conformance/tests/l0-static/internal-services-publish-no-public-dns` re-proves both directions
+  (present on internal, **absent** on public) on every gate run.
+  - The route itself, the wildcard TLS and LAN reachability are **unchanged** — only the public
+    record is withdrawn. The internal split-horizon answer is Pi-hole's job (R-DNS-03), which is why
+    withdrawing these records requires Pi-hole to be answering the LAN authoritatively first: the
+    zone has no `*.home.keithjackson.dev` wildcard, and `*.keithjackson.dev` does not match two
+    labels, so a withdrawn name is a public NXDOMAIN with no fallback.
+  - Why not a cluster-wide ExternalDNS opt-in filter (`labelFilter`, which v0.21.0 supports for
+    both configured sources): seven published names come from hand-authored `platform/`/`apps/`
+    manifests that carry no `exposure` field for a renderer to read, and an opt-in filter deletes
+    all seven the moment it is set. Per-resource exclusion has exactly the blast radius of the
+    defect. The filter stays available as hardening once those seven are adjudicated — see
+    `platform/externaldns/helmrelease.yaml` and the register in the L0 check.
+- `public` renders the record but the renderer does **not** yet set a target: the record still
+  resolves to the shared Gateway VIP, i.e. an RFC1918 address, so a `public` service is not in fact
+  publicly reachable. Fixing that is **not** a renderer change on v0.21.0 —
+  `source/gateway.go` reads `external-dns.alpha.kubernetes.io/target` only from the **Gateway** (and
+  a ListenerSet), never from an HTTPRoute, so a per-service target override is not expressible while
+  the public services share the `shared` Gateway. The open decision is recorded in
+  `platform/externaldns/helmrelease.yaml`.
