+## How images are built
+
+This repo's three images — `toolbox` (`infra/devcontainer/`), `agent-runner` (`infra/agent/`,
+built `FROM` the toolbox) and `conformance-runner` (`conformance/incluster/`) — are built,
+verified and published by [`images.yaml`](images.yaml), never from a workstation
+(operator rule, 2026-10-29). The logic is in [`scripts/images.sh`](scripts/images.sh).
+
+**The builder is rootless BuildKit** ([`platform/buildkit/`](../../platform/buildkit/README.md)),
+reached over mTLS with a pinned `buildx` — no job here touches a Docker daemon, privileged or
+otherwise (operator decision on PR #81). The client certificate reaches jobs as the Actions
+secrets `BUILDKIT_CA`, `BUILDKIT_CLIENT_CERT`, `BUILDKIT_CLIENT_KEY`.
+
+**Verification is a build target.** Each Containerfile ends in a `verify` stage that runs every
+in-image assertion at build time as the non-root uid with `RUN --network=none` (tool presence and
+pinned versions, `PM_SELFTEST=1 pm-dispatch`, the pm-worker probe, the `conformance-clone`
+refusals, no writable path outside the workspace). The pipeline builds `<image>-verify` before it
+builds, let alone pushes, the image. Build args come from each image's own
+`build-image.sh --print-build-args`, which is also the local podman path — so the recipe and the
+proof exist once.
+
+| Trigger | What happens |
+|---|---|
+| pull request touching an image's inputs | build + verify only. Nothing is pushed and **no registry credential is referenced** |
+| push to `main` touching an image's inputs | build + verify + publish to `gitea.home.keithjackson.dev/home-network/<image>` as `sha-<commit>` (immutable) and `main` (moving); the **registry-returned** digest is in the job summary |
+| `workflow_dispatch` | the same as a push when run on `main` (all images by default); verify-only elsewhere |
+
+Only images whose inputs changed are built. The publish job **never writes to git**: Renovate
+follows each image's `main` tag through a `# renovate-digest:` marker next to every digest
+reference (`platform/pm-agent/`, `infra/agent/versions.env`, `conformance/versions.env`) and
+opens the bump PR, which goes through the gate like anything else. A PR opened with the Actions
+token would not trigger the required gate, which is why it is Renovate's job and not this one's.
+
+Credential: the repository secret **`REGISTRY_PUSH_TOKEN`** (scope `write:package`, owned by an
+account with package write on the org). The automatic Actions token cannot push in Gitea 1.24.3
+— the reasoning, with source citations, is in the header of `images.yaml`. Retention:
+[`infra/gitea/registry-retention.sh`](../../infra/gitea/registry-retention.sh), an operator
+action, keeps every digest git pins plus the newest tags.
+
+Cost: the job shares the single act_runner slot with the gate, but the build itself runs in the
+`buildkitd` pod, not in DinD, so the runner's disk and memory are untouched. Until
+`platform/buildkit` is deployed and its client certificate copied
+(`infra/gitea/buildkit-client-secret.sh`), the job fails loudly at its builder preflight.

+# ═══════════════════════════════════════════════════════════════════════════════════════════════
+# "Container image creation, hosting and lifecycle must be part of CI/CD and the codebase, never a
+# one-off build/push from a workstation." Before this workflow, three images existed only as
+# workstation builds and NOTHING had ever been pushed to the Gitea registry: the Home-Network org's
+# package list was empty, platform/pm-agent/ pinned an all-zero digest and sat in ImagePullBackOff,
+# and conformance/versions.env carried an empty digest. Both build scripts said "publishing is an
+# operator action" — a step with no log, no recorded inputs and no verification anyone could read.
+#
+# WHAT IT DOES — the logic is in scripts/images.sh; this file only wires triggers and secrets.
+#   pull_request -> build + VERIFY only. No push, and no registry credential is referenced.
+#   push to main -> build + verify + PUBLISH to gitea.home.keithjackson.dev/home-network/<image>
+#   dispatch     -> same as a push when run on main; verify-only on any other ref.
+# Images: toolbox (infra/devcontainer), agent-runner (infra/agent, FROM toolbox) and
+# conformance-runner (conformance/incluster). Only images whose inputs changed are built.
+#
+# THE DIGEST LIFECYCLE — this workflow NEVER writes to git.
+#   1. publish pushes `sha-<commit>` (immutable) and `main` (moving), and prints the digest the
+#      REGISTRY returns in the job summary.
+#   2. Renovate (renovate.yaml) follows the `main` tag of each image through the
+#      `# renovate-digest:` markers next to every digest reference, and opens the bump PR.
+#   3. That PR goes through the gate like any other change, and Flux deploys it.
+# The bump PR is Renovate's and not this job's because a PR opened with the Actions token does not
+# trigger workflows, so it could never pass the REQUIRED gate check; Renovate's token is a real
+# user's.
+#
+# THE PUSH CREDENTIAL — `REGISTRY_PUSH_TOKEN`, a repository Actions secret, referenced BY NAME.
+# The automatic Actions token CANNOT be used. Gitea 1.24.3 source, verified:
+#   * services/auth/basic.go (Basic.Verify) turns a task token into the pseudo-user
+#     `gitea-actions` (ActionsUserID -2) and sets NO token scope;
+#   * routers/api/packages/container/container.go (Authenticate, the /v2/token exchange every
+#     docker client uses) then requires read:package / write:package / all scope and answers 401;
+#   * services/context/package.go (determineAccessMode) has `// TODO: ActionUser permission check`
+#     and no branch for that user, so even past login it would get at most READ on a public org.
+# So: a personal access token with scope `write:package`, minted by an account that has package
+# WRITE on the Home-Network org (org owner, or a team with the Packages unit at write). A dedicated
+# bot account in a packages-only team is the least-privilege choice. The username sent with it is
+# not checked by Gitea (basic.go resolves the owner from the token), so `vars.REGISTRY_PUSH_USER`
+# is optional and only labels the login.
+#
+# THE BUILDER — rootless BuildKit (operator decision on PR #81, 2026-10-29).
+# The act runner's job containers get NO Docker daemon (act_runner 0.2.11 forces docker_host "-"
+# for a tcp:// DinD, and gitea/act strips every bind when valid_volumes is empty — measured on
+# this PR's first run), and handing them the privileged DinD daemon would be root on the node for
+# anyone who can push a branch. So images are built by platform/buildkit/: a ROOTLESS buildkitd
+# (not privileged; uid 1000 in a user namespace), reached over mTLS at
+# buildkitd.buildkit.svc.cluster.local:1234 with a pinned `buildx` (remote driver). Its client
+# certificate reaches jobs as three Actions secrets — BUILDKIT_CA, BUILDKIT_CLIENT_CERT,
+# BUILDKIT_CLIENT_KEY — copied from cert-manager by infra/gitea/buildkit-client-secret.sh.
+# Pull requests get the client certificate (they must build) but never a registry credential.
+#
+# UNTIL platform/buildkit IS DEPLOYED (Flux applies it only after merge) THIS JOB FAILS, LOUDLY,
+# at its builder preflight. A skipped Gitea job reports `success`, so it is red on purpose.
+#

+          Images cannot be published without a registry credential, and this step fails rather
+          than skipping ON PURPOSE: a skipped Gitea job reports `success`, so skipping here would
+          make "nothing was published" look exactly like "published". That is how this repo went
+          a month with images that existed only on one workstation.
+
+          WHY NOT THE BUILT-IN ACTIONS TOKEN: Gitea 1.24.3 gives it no package scope at the
+          registry's /v2/token exchange (routers/api/packages/container/container.go,
+          Authenticate) — see the header of .gitea/workflows/images.yaml.
+
+          TO FIX: as an account with package WRITE on the Home-Network org (ideally a dedicated
+          bot in a packages-only team), create an access token with scope `write:package` and
+          nothing else, then add it to this repository as the Actions secret
+          REGISTRY_PUSH_TOKEN. Optionally set the Actions variable REGISTRY_PUSH_USER to that
+          account's name. Do not commit the token anywhere. Then re-run this workflow
+          (workflow_dispatch on main, images: all).

+# .gitea/workflows/scripts/images.sh — the image pipeline's driver (images.yaml calls this).
+#
+# Builds, verifies and (on main) PUBLISHES the three images this repo ships:
+#
+#   toolbox             infra/devcontainer/    the pinned dev/gate toolchain
+#   agent-runner        infra/agent/           FROM toolbox; the PM dispatcher + worker
+#   conformance-runner  conformance/incluster/ the in-cluster L2/L3 Chainsaw runner
+#
+# THE BUILDER (operator decision on PR #81): a ROOTLESS BuildKit daemon, platform/buildkit/,
+# reached over mTLS. No CI job may reach a privileged daemon, so there is no `docker build` and no
+# `docker run` here: this script drives buildkitd with a pinned `buildx` (remote driver) and
+# nothing else. The client certificate arrives as Actions secrets (BUILDKIT_CA,
+# BUILDKIT_CLIENT_CERT, BUILDKIT_CLIENT_KEY; infra/gitea/buildkit-client-secret.sh puts them
+# there). If the daemon is unreachable this FAILS LOUDLY — it never skips.
+#
+# VERIFICATION IS A BUILD TARGET. Each Containerfile ends in a `verify` stage that runs every
+# in-image assertion at build time (as the non-root uid, with RUN --network=none); this script
+# builds `<image>-verify` and only then the image. Build args come from each image's own
+# `build-image.sh --print-build-args`, the same list the local podman path uses.
+#
+# MODES (env MODE):
+#   verify   build the verify targets, never push, hold no registry credential. Pull requests.
+#   publish  verify, then build + push to ${REGISTRY}/${NAMESPACE}/<image> with tags
+#            `sha-<12 hex>` (immutable: never re-pushed) and `main` (moving; Renovate follows
+#            it). The digest recorded is the one the REGISTRY returns, read back after the push.
+#
+# WHAT GETS BUILT (env IMAGES): `auto` (default) diffs BASE_SHA..HEAD_SHA against each image's
+# inputs; otherwise a space-separated list. A change to the pipeline itself (images.yaml, this
+# file, platform/buildkit/versions.env) builds everything in verify mode, and nothing extra in
+# publish mode: re-publishing unchanged inputs would only mint new digests and churn Renovate PRs.
+#
+# THE agent-runner BASE:
+#   * verify mode -> FROM the toolbox built in this run, linked with a bake `target:` context —
+#     a pull request holds no registry credential and that toolbox exists in no registry. If the
+#     toolbox's inputs did not change it is built anyway, as the base.
+#   * publish mode, toolbox published in this run -> FROM the digest the registry just returned.
+#   * publish mode otherwise -> AGENT_BASE_IMAGE from infra/agent/versions.env (the published
+#     toolbox digest Renovate keeps current). If that is still the all-zero placeholder the
+#     toolbox has never been published, so it is built and published first (the bootstrap).
+#
+# LOOP-FREEDOM. Renovate turns each publish into a digest-bump PR. Those bumps land in
+# platform/pm-agent/ (no image input), conformance/versions.env (no image input) and
+# infra/agent/versions.env (agent-runner input -> ONE more agent-runner build, whose own bump
+# lands in platform/pm-agent/ and stops). The worker Job template is deliberately NOT tracked:
+# it is baked INTO agent-runner, so bumping it would rebuild agent-runner, mint a new digest,
+# bump it again, forever. pm-dispatch overwrites that field at runtime anyway.

-  # THE SPLIT-HORIZON ANSWERS. A dnsmasq `address=/<domain>/<ip>` entry answers that domain AND
-  # every subdomain of it, and dnsmasq resolves overlapping entries by LONGEST MATCHING DOMAIN —
-  # so the first line is a wildcard for the whole zone and each later line is a specific override.
-  # PRECEDENCE IS THEREFORE STRUCTURAL, not order-dependent: `unifi.${BASE_DOMAIN}` matches both
-  # line 1 and line 2, line 2 is the longer domain, line 2 wins. Rewriting these in any order
-  # changes nothing.
+  # THE LAN ANSWERS — AN EXPLICIT LIST, NOT A ZONE WILDCARD (2026-11-09). A dnsmasq
+  # `address=/<domain>/<ip>` entry answers that domain AND every subdomain of it (on LABEL
+  # boundaries: `pihole.` does not match `pihole-dns.`), and dnsmasq resolves overlapping entries by
+  # LONGEST MATCHING DOMAIN, so the order below is irrelevant. Every name NOT listed here is
+  # FORWARDED to the upstreams above and gets the PUBLIC answer.
  #
-  # A NEWLY ONBOARDED SERVICE NEEDS NO CHANGE HERE. Every catalog ingressRoute host is
-  # `<label>.${BASE_DOMAIN}` served by the shared Gateway, so the wildcard already answers it with
-  # ${GATEWAY_VIP} — the same guarantee, and the same reasoning, as the `template IN A` block in
-  # platform/coredns/coredns-custom.yaml. Add a line here ONLY for a service that does not live
-  # behind the Gateway: an L4 LoadBalancer on its own pinned VIP. Those are enumerated from the
-  # repo, not from memory — grep `external-dns.alpha.kubernetes.io/hostname` on a Service, which
-  # is the annotation that means "this Service publishes its own hostname at its own address":
-  # apps/vms/unifi/50-service-l4.yaml (unifi -> ${UNIFI_L4_VIP}) and
-  # platform/crafty/service-l4.yaml (crafty-mc -> ${CRAFTY_L4_VIP}). Those two, plus PiHole's own
-  # resolver address, are the complete set of exceptions today.
+  # WHY NO WILDCARD ANY MORE. Until 2026-11-09 the first entry was `address=/${BASE_DOMAIN}/
+  # ${GATEWAY_VIP}`, answering the whole zone. That made sense while every public record was a
+  # DNS-only CNAME to `wan.${BASE_DOMAIN}` (no NAT hairpin on this router, so the LAN NEEDED a
+  # private answer). Since PR #156 every public name is a PROXIED CNAME to the Cloudflare Tunnel
+  # (platform/externaldns/README.md), which works identically from the LAN — so a name that is
+  # public now SHOULD resolve publicly from the LAN too, and the LAN no longer depends on PiHole for
+  # it: a client that bypasses PiHole (DoH browser, phone private DNS, the router's fallback) gets
+  # the same working answer. The wildcard had also become actively misleading: it answered names
+  # that exist nowhere (`wan.` itself resolved to the Gateway VIP on the LAN).
  #
-  # AAAA needs nothing: dnsmasq answers a AAAA query for an `address=`d name with NODATA
-  # (NOERROR, no answer), so IPv6-capable clients fall back to the A record instead of getting
-  # NXDOMAIN — the same behaviour coredns-custom hand-writes a `template IN AAAA` block for.
+  # WHAT IS LISTED, and why each — enforced by conformance/tests/l0-static/pihole-lan-names:
+  #   -> ${GATEWAY_VIP}, LAN-ONLY: every HTTPRoute disowned from public DNS
+  #      (`external-dns.alpha.kubernetes.io/controller: none`, i.e. catalog `exposure: internal`,
+  #      plus plex and headlamp) — jackett, pihole, plex, qbittorrent, radarr, semaphore, sonarr,
+  #      headlamp. These have NO public record and the tunnel 404s them, so THIS LINE IS THEIR ONLY
+  #      PATH: drop one and the app is unreachable everywhere. A NEWLY ONBOARDED `internal` SERVICE
+  #      MUST BE ADDED HERE (the L0 check fails until it is). A new `public` service needs nothing.
+  #   -> ${GATEWAY_VIP}, PUBLIC BUT KEPT ON THE LAN PATH: gitea (git push, LFS, container registry)
+  #      and nextcloud (uploads) — Cloudflare's proxy caps a request body at 100 MB and a response
+  #      at 100 s, which a large push or upload exceeds; keycloak and auth (oauth2-proxy) — so the
+  #      OIDC login of those two LAN-path apps stays on the same path as the apps themselves.
+  #   -> their own L4 VIPs: unifi (${UNIFI_L4_VIP}) and crafty-mc (${CRAFTY_L4_VIP}) are not behind
+  #      the Gateway (grep `external-dns.alpha.kubernetes.io/hostname` on a Service:
+  #      apps/vms/unifi/50-service-l4.yaml, platform/crafty/service-l4.yaml); their public records
+  #      are DNS-only A records to the same RFC1918 VIPs, which this router's rebind protection
+  #      strips, so the LAN answer is still required. pihole-dns (${PIHOLE_DNS_VIP}) is PiHole's own
+  #      resolver address; plex-vip (${PLEX_L4_VIP}) is below.
+  # NOT listed, deliberately, so they resolve via Cloudflare from the LAN as from anywhere: the apex,
+  # grafana, crafty, seerr. In-cluster (platform/coredns/coredns-custom.yaml) and node
+  # (/etc/hosts pins, node_baseline_hosts_pins) resolution are separate and unchanged.
+  #
+  # AAAA: dnsmasq answers a AAAA query for an `address=`d name with NODATA (NOERROR, no answer),
+  # so IPv6-capable clients fall back to the A record instead of getting NXDOMAIN — the same
+  # behaviour coredns-custom hand-writes a `template IN AAAA` block for. Unlisted (proxied) names
+  # now get Cloudflare's real A and AAAA answers.

+  # plex-vip -> ${PLEX_L4_VIP} (added 2026-10-04) is the name of the tcp/32400 LoadBalancer
+  # (apps/wave-0/plex-remote.yaml) and the domain of the certificate Plex serves there
+  # (catalog/plex.yaml CERTDOMAIN / customCertificateDomain, Secret `plex-vip-tls`). It is NOT what
+  # Plex advertises any more (ADVERTISE_IP is a resolver-independent plex.direct name since
+  # 2026-10-05) and it has NO public record, so this entry is its only resolution — kept for

+  # before it existed the zone wildcard answered it with ${GATEWAY_VIP}, where nothing listens on
+  # 32400; without it now, the name is NXDOMAIN.

+  # ── local-ttl=60 — THE SPLIT-HORIZON ANSWER MUST BE CACHEABLE ────────────────────────────────
+  # MEASURED 2026-10-18, diagnosing "DNS flapping between the cluster ingress and the public IP":
+  #
+  #   dig home.keithjackson.dev @192.168.2.23 (pihole)  -> 192.168.2.20                TTL=0
+  #   dig home.keithjackson.dev @1.1.1.1      (public)  -> wan.home.keithjackson.dev   TTL=300
+  #   dig home.keithjackson.dev @192.168.2.1  (router)  -> wan....  TTL=153 -> 148 -> 143
+  #
+  # dnsmasq answers `address=` entries with **TTL 0** unless told otherwise, and that is the whole
+  # bug. The SOHO router forwards LAN queries to PiHole and CACHES the result, so:
+  #   * the CORRECT answer is UNCACHEABLE (TTL 0) -- the router must re-query PiHole on every
+  #     single lookup, which is maximum exposure to any momentary gap; while
+  #   * the WRONG answer is CACHEABLE FOR 5 MINUTES -- the instant the router falls back to its
+  #     upstream (standard forwarder behaviour when the forward target does not answer) it latches
+  #     the public WAN address and serves it to EVERY LAN CLIENT for the public record's 300s TTL.
+  # The decrementing TTL on the router's reply above is the proof it caches rather than forwarding
+  # live. So ONE sub-second PiHole gap -- a pod restart, an L2 announcement lease moving, an ARP
+  # flap, a kured node reboot -- becomes FIVE MINUTES of the whole house resolving to the WAN IP.
+  # That asymmetry, not the gap, is why this is visible as "flapping" rather than a blip.
+  #
+  # 60s is a deliberate floor, not a tuning knob: long enough to ride out a pod restart and a lease
+  # re-election (both seconds), short enough that a genuine VIP change still propagates inside a
+  # minute. These VIPs are pinned by name (`lbipam.cilium.io/ips`) and effectively static, so the
+  # propagation cost is theoretical while the flap it prevents is measured. If flaps persist across
+  # LONGER outages, raising this toward the public record's 300 would cover them -- at the cost of
+  # the same delay on a real change. It does NOT help when PiHole is down longer than the TTL: the
+  # cache expires, the router falls back, and the public answer latches again. That is a real
+  # outage, and the fix for it is PiHole availability, not DNS caching.
+  #
+  # SINCE 2026-11-09 THE LATCH IS MOSTLY HARMLESS. The measurement above predates the tunnel: the
+  # public answer was then `wan.`, unreachable from the LAN. Now the public answer for every
+  # proxied name is Cloudflare, which works from the LAN, and those names are not listed below at
+  # all. A latch still bites only the listed names: gitea/nextcloud/keycloak/auth fall back to
+  # Cloudflare (working, but under its 100 MB / 100 s limits); the LAN-only names and the L4 VIPs
+  # get NXDOMAIN or a stripped answer until the router re-queries PiHole.

+#
+# Render platform/keycloak/passkey-desired-state.yaml FROM
+# platform/keycloak/keycloak-realm-import.yaml.
+#
+# WHY THIS EXISTS
+# ---------------
+# The Keycloak realm import is a ONE-SHOT that fails OPEN: once it rests at
+# Done=True / Started=False it never re-runs. Measured on prod 2026-10-18, hours
+# after the passkey declaration merged:
+#
+#     kubectl -n keycloak get keycloakrealmimport homelab -o jsonpath=...status
+#     Done=True  Started=False  HasErrors=False
+#
+# So the WebAuthn passwordless policy and the restructured `browser-mfa` flow that
+# keycloak-realm-import.yaml declares are INERT. They are in git, Flux applied
+# them, and they reach the realm never. platform/keycloak/passkey-reconciler.yaml
+# is the level-triggered loop that closes that; this renderer supplies the DESIRED
+# STATE it converges towards.
+#
+# THE ONE VALUE THAT IS NOT RENDERED: `bind-browser-flow`, git's switch for whether the
+# reconciler may BIND its verified candidate browser flow (one atomic PUT of the
+# realm's browserFlow). It is an operator DECISION -- "I have tested the candidate
+# flow in a browser; make it the login path" -- not a fact derivable from the realm
+# import, so it cannot be generated. It is instead CARRIED THROUGH from the committed
+# file: --write preserves it, --check accepts any value of it that is exactly the
+# string "true" or "false" and rejects everything else (an unquoted YAML true is a
+# bool, which a ConfigMap rejects at apply time -- failing the whole platform-config
+# Kustomization -- so it is refused HERE, at merge time). An absent file or key
+# renders as "false". Going live is therefore a one-line PR flipping that line.
+#
+# THE CONSTRAINT THAT SHAPES IT: the reconciler pod runs with
+# automountServiceAccountToken: false, exactly like its client-secret sibling. It
+# has NO Kubernetes API access at all, by design (R-SEC-02) — so it cannot read the
+# KeycloakRealmImport CR to learn what the realm is supposed to look like. Its input
+# must be MOUNTED. Hence a ConfigMap.
+#
+# THAT IS ALSO WHY THIS IS A RENDERER AND NOT A HAND-WRITTEN ConfigMap. A
+# hand-authored copy of the policy would be a SECOND SOURCE OF TRUTH for the RP ID,
+# the user-verification requirement and the whole flow tree — free to disagree with
+# the realm import. "Two declarations that can disagree" is the same shape as the
+# bug this whole effort is closing. So the ConfigMap is GENERATED from the realm
+# import and the generation is GATED:
+# conformance/tests/l0-static/keycloak-passkey-reconciler/check.sh runs this script
+# with --check on every merge, and the merge fails if the committed file is not what
+# this renderer produces. Same render==golden idiom as
+# ci/render-keycloak-client-urls.py, catalog/render.py and ci/render-golden.sh.
+#
+# STRINGS ARE COPIED VERBATIM, NEVER RE-DERIVED. webAuthnPolicyPasswordlessRpId is
+# written in the realm import as the Flux substitution token ${BASE_DOMAIN}, and it
+# is carried through into the ConfigMap CHARACTER FOR CHARACTER. Both files are
+# rendered by the SAME Flux Kustomization (./platform-config, whose
+# postBuild.substituteFrom reads cluster-vars), so both are substituted in the same
+# pass with the same value and cannot disagree about what the base domain is. This
+# renderer never parses, splits or reconstructs a hostname and never reads
+# cluster-vars — there is no second place the domain is decided.
+#
+# THE ONE THING THIS RENDERER DERIVES RATHER THAN COPIES
+# -----------------------------------------------------
+# The enrolment required action, `webauthn-register-passwordless`. It is
+# deliberately NOT declared in the realm import, and the import's own header
+# explains at length why declaring it there would be actively DANGEROUS: Keycloak
+# 26.0.6 treats `requiredActions` in a realm representation as REPLACE, not merge,
+# so declaring one action imports exactly that action plus delete_account and skips
+# DefaultRequiredActions.addActions entirely — deleting CONFIGURE_TOTP,
+# UPDATE_PASSWORD, VERIFY_EMAIL and seven more. Losing CONFIGURE_TOTP is a hard
+# lock-out of every platform-admin, because auth-otp-form in the browser flow still
+# demands a TOTP they could then never enrol.
+#
+# So the required action cannot be copied from the import, because it is correctly
+# absent from it. It is instead DERIVED, as a consequence of what the import DOES
+# declare:
+#
+#   IF the declared browser flow contains a `webauthn-authenticator-passwordless`
+#   execution, THEN passkey logins are offered, THEREFORE the enrolment action must
+#   be registered and enabled — and NOT a defaultAction, because the import's whole
+#   stated posture is "additive and optional" and a defaultAction forces enrolment
+#   on every user at next login.
+#
+# This is a derivation, not a second declaration: there is no value here that a
+# human could edit into disagreement with the import. If the import stops declaring
+# the passkey execution, this renderer stops emitting the required action (and
+# fails, because then the whole desired state is empty of passkey intent).
+#
+# WHAT IS DELIBERATELY NOT EXPORTED
+#   * the TWO-FACTOR webAuthnPolicy* family. Nothing in this realm uses the
+#     `webauthn-authenticator` two-factor authenticator; the passwordless
+#     authenticator reads getWebAuthnPolicyPasswordless() only, so a policy written
+#     into the two-factor family is a silent no-op. Exporting it would hand the
+#     reconciler a write surface with no purpose.
+#   * `clients`, `users`, `groups`, `roles`. Client secrets and client URLs are the
+#     SIBLING reconciler's surface (platform/keycloak/client-secret-reconciler.yaml),
+#     and users/groups/roles are nobody's — prod's real user and the media-users /
+#     platform-admins / viewers groups must survive every run of everything.
+#   * execution `priority`. It is consumed here to ORDER the exported executions
+#     (Keycloak returns them in priority order), but the numbers themselves are not
+#     exported: the reconciler compares the resulting SEQUENCE, which is what
+#     actually determines behaviour. Exporting the integers would make a
+#     priority renumbering that changes no ordering read as drift.

+# GENERATED FILE — DO NOT EDIT BY HAND, except the one bind-browser-flow line below.
+#
+#   source:      platform/keycloak/keycloak-realm-import.yaml (spec.realm)
+#   regenerate:  python3 ci/render-keycloak-passkey-policy.py --write
+#   gated by:    conformance/tests/l0-static/keycloak-passkey-reconciler
+#                (runs this renderer with --check on every merge)
+#
+# WHAT THIS IS: the DESIRED STATE for the `homelab` realm's PASSKEY configuration —
+# the WebAuthn passwordless policy, the enrolment required action, and the declared
+# browser authentication flow tree. platform/keycloak/passkey-reconciler.yaml mounts
+# it and (a) converges the policy and the required action onto it, (b) builds the
+# declared flow tree BLUE/GREEN under a new alias and verifies it by readback, never
+# writing the flow users are logging in through, and (c) BINDS that verified flow as
+# the realm's browserFlow ONLY when `bind-browser-flow` below is "true".
+#
+# EVERYTHING HERE IS GENERATED EXCEPT ONE LINE: `bind-browser-flow`. That is an
+# operator decision, carried through by the renderer from this committed file (see
+# ci/render-keycloak-passkey-policy.py). It defaults to "false".
+#
+# WHY IT IS A SEPARATE OBJECT: the realm import is a ONE-SHOT that never re-runs
+# once Done=True, so a realm-level field or a flow edited in git never reaches the
+# realm. Measured on prod 2026-10-18, hours after the passkey declaration merged:
+# Done=True / Started=False, with the whole passkey block inert. The reconciler is
+# the level-triggered loop that closes that; this file is what it reconciles
+# TOWARDS.
+#
+# WHY IT IS GENERATED AND NOT AUTHORED: a hand-written copy of the RP ID, the
+# user-verification requirement and the flow tree would be a second source of truth,
+# free to disagree with the realm import — the same "two declarations that can
+# disagree" shape as the bug being closed. It is rendered from the import and the
+# render is gated, so the two cannot drift.
+#
+# STRINGS ARE VERBATIM: webAuthnPolicyPasswordlessRpId is the ${BASE_DOMAIN}
+# substitution token exactly as the realm import writes it. Both files are rendered
+# by the SAME Flux Kustomization (./platform-config), so the token resolves to the
+# same value in both and the domain is decided in exactly one place.
+#
+# `requiredAction` is the ONE entry that is DERIVED rather than copied: the realm
+# import deliberately declares no `requiredActions` block, because Keycloak 26.0.6
+# treats that as REPLACE and declaring one action would delete CONFIGURE_TOTP and
+# nine more (a hard lock-out of every platform-admin). It is derived instead from
+# the presence of a webauthn-authenticator-passwordless execution in the flow:
+# passkeys are offered, therefore enrolment must be enabled — and defaultAction is
+# false, so enrolment stays opt-in.
+#
+# A field NOT declared on the realm in the import is simply ABSENT here, and the
+# reconciler leaves it alone. Absence means UNMANAGED, never "force to a default".

+# Flux Kustomization: Cloudflare Tunnel connector — reconciles ./platform/cloudflared.
+#
+# ISOLATION IS THE POINT OF THIS FILE. The Deployment it applies CANNOT become Ready until the
+# operator enrols the tunnel (runbooks/cloudflare-tunnel.md): it ships with REPLACE-ME credentials
+# and a placeholder UUID, and a wrong or revoked credential later produces the same state. So:
+#
+#   * ITS OWN Kustomization, not a line in platform/kustomization.yaml. `platform` is wait:true and
+#     gates platform-config, which gates every apps wave; an unenrolled tunnel there would be a
+#     platform-wide stall ON MERGE, with the cause (a missing manual step) invisible from any Flux
+#     condition. Same reasoning, and same failure shape, as vpn-ingress's unfilled server key.
+#   * wait: false. Its pods are legitimately not-Ready whenever the credentials are absent or the
+#     edge is unreachable. Health is reported by the CloudflaredTunnelDown / ReplicasDegraded
+#     alerts (platform/cloudflared/alerts.yaml), not by this Kustomization's Ready condition —
+#     which reaches Ready on APPLY success.
+#   * NOTHING dependsOn THIS, and nothing should. A missing or invalid credentials Secret can then
+#     only ever affect the tunnel itself. conformance/tests/l0-static/cloudflared-ingress-rules
+#     fails the gate if any Kustomization gains `dependsOn: cloudflared`, or if this one stops
+#     being wait:false.
+#   * No Certificate, no HelmRelease, no CRD: nothing in the path for Flux's health checks to wait
+#     on even if wait were flipped (the Certificate-stall lesson).
+#
+# dependsOn: [platform-config] — A REAL EDGE.
+#   1. CRD ORDERING: PodMonitor and PrometheusRule are monitoring.coreos.com CRs whose CRDs are
+#      installed by kube-prometheus-stack in `platform`; platform-config dependsOn platform, so this
+#      edge carries that guarantee transitively (Flux aborts a whole pass on an unknown kind).
+#   2. THE FAR SIDE OF THE TUNNEL: the Gateway (and so the cilium-gateway-shared Service the ingress
+#      rules point at) is applied by platform-config. A tunnel that comes up before its origin is a
+#      support call.
+#
+# ZERO EFFECT ON LIVE TRAFFIC UNTIL DNS MOVES. Cloudflare only sends a hostname through a tunnel
+# when that hostname's DNS record is a CNAME to <uuid>.cfargotunnel.com. This change creates no

-# then trusts. So this builds locally, proves the toolchain works INSIDE the image as the
-# non-root uid the policy demands, and prints the exact `podman push` line for a human.
+# THIS SCRIPT NEVER PUSHES — and nobody pushes this image from a workstation either.
+# Publishing is done by CI: .gitea/workflows/images.yaml builds the SAME Containerfile on
+# rootless BuildKit (platform/buildkit/), taking its build args from `--print-build-args`, and
+# on a push to `main` pushes it to the Gitea registry and records the registry-returned digest
+# in the job summary; Renovate then opens the pull request that moves conformance/versions.env
+# onto that digest. The proof that the image works is the Containerfile's `verify` stage, which
+# this script (podman locally) and CI both build.
 #
 # VERSIONS ARE NOT DEFINED HERE. They are read from infra/devcontainer/versions.env, the
 # single source of truth (CHAINSAW_VERSION, KUBECTL_VERSION, FEDORA_VERSION) — the same
 # pins the toolbox gate runs with. Nothing in this file invents a version.
 #
-# THE DIGEST CAVEAT — read it before pasting a digest into anything.
-# The digest printed here is the LOCAL manifest digest. It is normally identical to the
-# registry digest (podman pushes the manifest it already has rather than recompressing),
-# but that is a property of the push, not a guarantee. So the push command below uses
-# `--digestfile`: the digest the registry actually returns is the authoritative one, and
-# that is the one that goes into conformance/versions.env.
+# NO DIGEST IS PRINTED. A manifest digest does not exist until a registry holds the manifest,
+# and the only digest anything may pin is the one the REGISTRY returns. CI captures that at
+# push time (.gitea/workflows/scripts/images.sh) and Renovate carries it into
+# conformance/versions.env.

+PARALLELISM (--jobs, env CONF_OFFLINE_JOBS)
+-------------------------------------------
+The checks are independent processes, so they run in a bounded thread pool (one `bash` child
+per worker). Default: min(8, usable CPUs); `--jobs 1` is the old serial runner exactly. Each
+check's stdout+stderr is CAPTURED and only reported after every check has finished, in the
+ORDER THE DIRS WERE GIVEN, so the log, the JUnit and the step summary are byte-for-byte
+independent of which check finished first (only the trailing "[N.Ns]" wall-time on each
+status line varies). The 0/1/3 aggregation runs over the same ordered case list as before.
+
+Parallel-safety is a property of the CHECKS, not of this runner: every check must keep its
+scratch state in a private mktemp/mkdtemp dir and must not write into the tree or a fixed
+path. The audit that established that for the current set is recorded in
+decisions/2026-11-08-parallel-l0-checks.md; a new check that needs shared state must say so.
+
+Nested pools: the keycloak reconciler checks run their own mutation suites in a pool
+(mutations.py, env MUTATION_JOBS). When this runner is itself parallel it exports a SMALLER
+MUTATION_JOBS (unless the caller already set one), so the two suites share the CPUs the
+other jobs-2 checks are not using instead of each taking min(8, CPUs). See inner_jobs().

+# L0 static check (offline, no cluster) — cloudflared-ingress-rules
+# Serves: R-NET-01 / R-NET-02 (default-deny; allow rules declarative and scoped), and the four
+#         operator decisions of 2026-11-08 recorded in decisions/2026-11-08-cloudflare-tunnel.md.
+#
+# WHY THIS EXISTS. platform/cloudflared/config.yaml is the whole of what the internet can reach
+# through the Cloudflare Tunnel. A one-line edit there — a rule pointing at the Kubernetes API, a
+# LAN-only hostname moved below the wildcard, a dropped catch-all — publishes something the operator
+# decided must never be public, and nothing in the cluster turns red: the tunnel stays connected and
+# the Kustomization stays Ready. So the decisions are asserted here, on every gate run.
+#
+# GIVEN the repository as authored,
+# THEN  (1) every ingress rule's `service` is `http_status:404` or EXACTLY the shared Gateway's
+#           in-cluster Service, derived from platform/gateway/gateway.yaml (so a Gateway rename
+#           fails here rather than in production) — which by construction excludes the
+#           Kubernetes API, and a named deny-list says so explicitly when it is violated;
+#       (2) each LAN/VPN-only hostname (plex, plex-vip, jackett, pihole, pihole-dns, semaphore,
+#           qbittorrent, radarr, sonarr, headlamp, unifi, crafty-mc) has a rule mapping it to http_status:404 that comes BEFORE any
+#           Gateway-bound rule (cloudflared matches first-rule-wins);
+#       (3) the apex and the wildcard are the Gateway rules, with matchSNItoHost, and nothing
+#           disables origin TLS verification; the last rule is a hostname-less 404 catch-all;
+#       (4) the egress CiliumNetworkPolicy admits none of kube-apiserver/host/remote-node/
+#           cluster/all and no CIDR rule, and its backend selector excludes the LAN-only
+#           namespaces (the second, independent layer behind (2));
+#       (5) the Flux tier is ISOLATED: its own Kustomization, wait:false, not listed in
+#           platform/kustomization.yaml, nothing anywhere dependsOn it, and both overlays carry its
+#           SOPS decryption patch — so a missing or invalid credential can stall nothing else;
+#       (6) the rule evaluator is not vacuous: it is run against mutated copies of the real config
+#           (an API rule added, plex moved below the wildcard, the catch-all removed) and must
+#           flag each one;
+#   AND (7) every Secret volume the container mounts — the tunnel credentials above all — is
+#           READABLE by the container's run-as identity, modelled the way the kubelet lays it out:
+#           files owned by uid 0, group-owned by fsGroup if set (else gid 0), with the item mode or
+#           defaultMode (API default 0644). The identity is the container securityContext over
+#           the pod's; the process's groups are runAsGroup + fsGroup + supplementalGroups. An
+#           unset runAsUser is a FAIL, not a pass: the image default cannot be read offline. The
+#           model is deliberately conservative — it does not credit the kubelet's habit of
+#           OR-ing group-read into fsGroup-owned volumes, so 0400+fsGroup fails here though it
+#           would work. Self-tested by mutation (fsGroup removed; mode 0400; runAsUser unset).
+#           This is the 2026-11-08 CrashLoop: runAsUser 65532, no fsGroup, 0440 root:root.
+#
+# NOT proven (static): that Cloudflare routes only the hostnames whose DNS points at the tunnel,
+# that the Gateway's certificate validates from cloudflared, or that Envoy enforces (4) — those are
+# runtime properties, verified by the operator per runbooks/cloudflare-tunnel.md.

+# Once it rests at Done=True the operator never re-runs it, so the WebAuthn passwordless

+# them changed nothing about how anyone logs in, and nothing anywhere said so.
+# Declarative config that silently does not apply is not declarative config.
+#
+# GIVEN the repository as authored,
+# THEN  the reconciler's desired state is GENERATED from the realm import (so the RP ID —
+#       which is baked into every passkey at enrolment and can NEVER be re-keyed — is
+#       declared exactly once); both files are rendered by the SAME Flux Kustomization, so
+#       their ${BASE_DOMAIN} token cannot resolve to two values; the renderer's exported
+#       policy keys and the reconciler's writable keys are the SAME tuple; the realm
+#       import declares NO requiredActions block (26.0.6 treats it as REPLACE, which would
+#       delete CONFIGURE_TOTP and lock out every platform-admin); the enrolment action is
+#       enabled but NOT a defaultAction, so enrolment stays opt-in; the reconciler carries
+#       no ServiceAccount token, mounts only what it needs, passes no mode flag, and
+#       contains no dollar sign; the endpoint allow-list contains NO delete, NO
+#       single-execution or config-edit write, and NO required-action write for any alias
+#       other than the one named literally; the protected-subtree guard exists, is wired
+#       into the single request choke point and is fail-closed; the SIBLING client-secret
+#       reconciler's allow-list is NOT widened; and the reconciler's own `--selftest`
+#       (extracted from the shipped ConfigMap and executed) proves compare-then-write,
+#       idempotence, strict read-modify-write, the RpEntityName gate, the bound flow and
+#       its sub-flows unwritable, the git bind switch and a rollback that sticks, the
+#       conditional-OTP regression and fail-closed — with mutations.py proving that
+#       selftest can FAIL.
+#
+# WHY THE FLOW IS BUILT BLUE/GREEN AND BOUND ONLY ON GIT'S SAY-SO, asserted here rather
+# than only argued: converging a five-flow, ten-execution restructure needs
+# create-subflow, create-execution, set-requirement and bind-config as SEPARATE admin API
+# calls with no transaction. Doing that to the BOUND flow means a run that dies between
+# them leaves a HALF-BUILT FLOW AS THE LOGIN PATH for Grafana, Gitea, Nextcloud, Headlamp,
+# Semaphore, PiHole, Crafty, the *arr stack AND kubectl — this repo has had a total SSO
+# outage from a realm change (2026-09-06), and the conditional-OTP sub-flow once 403'd
+# every platform-admin. So every multi-call write lands on a NEW, unused candidate flow,
+# which is verified by readback before anything is bound. Binding it is then ONE atomic
+# PUT of browserFlow, made only when passkey-desired-state.yaml sets
+# bind-browser-flow: "true" (default "false"): an untested login flow never goes live on
+# a schedule tick, and with the switch off an operator's rollback is never undone.
+#
+# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (git + PyYAML +
+# stdlib); conformance/run.sh --layer l0 and ci/l0.sh run it directly, and this Chainsaw
+# Test wraps the SAME script.
+#
+# NOT proven here: that the LIVE realm's policy, enrolment action or browser flow match
+# git (that is cluster state — the reconciler's `--audit` mode is the read-only probe for
+# it, and NO L2 test is added by this change, so the live realm is UNVERIFIED by CI);
+# that a passkey ceremony actually completes or that the ALTERNATIVE fork degrades to the
+# password form (needs a real browser against a real realm); that the five flow-building
+# admin-API calls behave against a live Keycloak the way the 26.0.6 source says they do

+#   Done=True  Started=False  HasErrors=False
+#
+# A KeycloakRealmImport is a ONE-SHOT. Once it rests at Done=True the operator never
+# re-runs it, so every realm-level field and every flow declared after the FIRST
+# import is inert — in git, applied by Flux, reported Ready, reaching the realm
+# never. The same shape as the 2026-09-06 client-secret incident (12 prod clients
+# holding the literal `(env:...)` placeholder behind an entirely green cluster), and
+# the same fix: a level-triggered reconciler. This check is the static half.
+#
+# THE RECONCILER HOLDS WRITE ACCESS TO THE IDENTITY PROVIDER. That is the reason this
+# check is unusually thorough about its BLAST RADIUS rather than only its behaviour.
+#
+# GIVEN the repository as authored,
+# THEN  (1) THE DESIRED STATE IS DERIVED, NOT DECLARED TWICE: the reconciler's input
+#           (platform/keycloak/passkey-desired-state.yaml) is GENERATED from the realm
+#           import by ci/render-keycloak-passkey-policy.py, and this check RUNS the
+#           renderer with --check, so a hand edit that makes the two disagree is
+#           unmergeable. The RP ID is the sharpest case: it is baked into every passkey
+#           at enrolment and can NEVER be re-keyed, so two declarations that can skew
+#           about the domain is an unrecoverable-credential bug, not a cosmetic one.
+#       (2) BOTH FILES ARE RENDERED BY THE SAME FLUX KUSTOMIZATION.
+#           postBuild.substituteFrom is per-Kustomization, so a split would let the
+#           ${BASE_DOMAIN} token in the realm import and the one in the desired state
+#           resolve to two different values — and an RP ID mismatch invalidates every
+#           enrolled passkey with no error the user can act on.
+#       (3) THE DESIRED STATE USES NO SUBSTITUTION TOKEN THE REALM IMPORT DOES NOT, and
+#           declares no realm key outside the reconciler's write surface.
+#       (4) THE TWO WRITE SURFACES AGREE: the renderer's exported policy keys and the
+#           reconciler's POLICY_FIELDS are the SAME tuple. If they drifted, the renderer
+#           could emit a key the reconciler refuses (fail-closed forever) or the
+#           reconciler could accept a key the renderer never emits (dead surface).
+#       (5) THE RECONCILER MANIFEST IS SAFE AND WIRED: reconciled from BOTH cluster
+#           entrypoints, mounts exactly the ConfigMaps its code defaults to, carries NO
+#           ServiceAccount token, and contains no dollar sign (it ships inside a
+#           SUBSTITUTED Flux path, where an unescaped dollar-brace expansion is
+#           rewritten before any container runs).
+#       (6) THE CURRENTLY BOUND FLOW IS STRUCTURALLY UNWRITABLE — asserted against the
+#           SOURCE, not the comments. The flow converges BLUE/GREEN (build under a new
+#           alias, verify, flip browserFlow in one atomic PUT), so flow-create and
+#           execution-add endpoints ARE on the allow-list and their presence is not the
+#           hazard. What is asserted instead: nothing is DELETABLE (the superseded flow
+#           is the rollback target); the execution- and config-id-scoped write endpoints
+#           stay off the list because they carry no flow alias and so cannot be screened;
+#           no required-action write reaches any alias but the one named literally; and
+#           the guard the allow-list CANNOT express exists in the source and is wired
+#           into the single request choke point, FAIL-CLOSED until the live binding has
+#           been read. That last one is what the whole design rests on: a reconciler that
+#           half-rewrites the BOUND browser flow is a total SSO outage on a loop, and
+#           this repo has had one (2026-09-06).
+#      (6b) THE BIND IS GIT'S DECISION: the desired-state ConfigMap carries
+#           bind-browser-flow as exactly "true" or "false", the script reads it from the
+#           SAME mount, and the CronJob passes no flag that could widen it. With "false"
+#           (the default) the reconciler builds and verifies but never PUTs browserFlow,
+#           so an operator's rollback sticks; the selftest proves that end to end.
+#       (7) THE SIBLING RECONCILER IS UNTOUCHED: client-secret-reconciler.yaml's
+#           allow-list is NOT widened by this work. Its --selftest asserts it refuses
+#           /users, /groups, /roles, /authentication and the whole-realm endpoint, and
+#           its guarantee that prod's real user and the media-users / platform-admins /
+#           viewers groups survive every run must stay LITERALLY true.
+#       (8) THE RECONCILER'S BEHAVIOUR IS PROVEN, NOT ASSERTED: this check EXTRACTS the
+#           script from the ConfigMap and executes its `--selftest`, which drives the
+#           real code paths against an in-process stub Keycloak that MODELS the three
+#           Keycloak 26.0.6 behaviours that bite — the RpEntityName gate on the
+#           passwordless policy, the all-or-nothing policy rebuild that defaults every
+#           omitted key, and the required-action representation replace.
+#      (8b) AND THAT PROOF IS FALSIFIABLE: mutations.py injects plausible regressions
+#           one at a time and requires --selftest to CATCH every one. A passing suite
+#           proves nothing if it cannot fail, and "reported success while the realm was
+#           broken" is the exact failure this component exists to end.
+#   AND (9) THIS CHECK IS LOAD-BEARING: it DECLARES
+#           `conformance.home.k3s/scope: whole-repo` so ci/l0.sh runs it unconditionally
+#           via --include-scope, ci/gate.sh blocks the merge when the l0 stage fails, and
+#           ci/touched-requirements.sh maps platform/keycloak/ to these requirement IDs.
+#           An unreferenced test is precisely the "looks applied and isn't" failure this
+#           repo keeps hitting.
+#
+# NOT proven here (named honestly, in the style of the sibling L0 checks):
+#   - that the LIVE realm's policy, enrolment action or browser flow match git. That is
+#     cluster state. The reconciler's own `--audit` mode is the read-only probe for it
+#     and is what an L2 test should run; no such L2 test is added by this change, so the
+#     live realm is UNVERIFIED by CI.
+#   - that the declared browser flow actually WORKS as a login path. Nothing offline can
+#     prove that a passkey ceremony completes, that the ALTERNATIVE fork degrades to the
+#     password form, or that a platform-admin is still asked for TOTP. Those need a real
+#     browser against a real realm.
+#   - that the reconciler's first real run against prod will succeed. The flow is built
+#     through five admin-API endpoints whose request shapes were read from the 26.0.6
+#     source but never exercised against a live Keycloak.
+#   - that the admin credential decrypts to a usable password. Key PRESENCE is checkable
+#     offline; the plaintext is not, and must not be.
+#   - that the CronJob's image can be pulled or its schedule fires.

+# mutations.py -- prove the passkey reconciler's --selftest IS FALSIFIABLE.
+#
+# WHY THIS EXISTS
+# ---------------
+# A selftest that passes proves nothing on its own: a selftest asserting `True ==
+# True` also passes. This reconciler exists because a one-shot realm import
+# REPORTED SUCCESS while the realm was never converged (Done=True / Started=False
+# with the whole passkey block inert, measured on prod 2026-10-18), and the same
+# trap applies one level up -- a green test suite that cannot fail is the same lie
+# in a different place.
+#
+# It matters more here than for the sibling client reconciler, because this program
+# CONSTRUCTS AUTHENTICATION FLOWS and then REBINDS THE REALM'S LOGIN PATH. An
+# untested safety property on that surface is not a documentation gap, it is an
+# outage waiting for a schedule tick.
+#
+# So this injects a series of PLAUSIBLE regressions into the shipped script, one at
+# a time, and requires that --selftest FAILS for every one. A mutation that
+# SURVIVES means the suite does not actually check that property, and the check
+# fails, naming it.
+#
+# THE FIRST SIX ARE THE BLUE/GREEN SAFETY ARGUMENT ITSELF. The design builds a new
+# flow under an unused alias, verifies it, and flips `browserFlow` in one atomic
+# write -- never mutating the flow users are logging in through. Each of those
+# properties is enforced in code; these mutations are the proof that the enforcement
+# is load-bearing rather than commentary. Several model the obvious "simplification"
+# someone will propose:
+#   * "just build it under the declared alias, the suffix is ugly"
+#   * "bind it first, then check -- the check is just belt and braces"
+#   * "the protected-alias screen is redundant, the allow-list covers it"
+# Every one of those would be a total SSO outage waiting to happen.
+#
+# ANCHORS ARE AUTHORED AGAINST THE EXTRACTED SCRIPT, not against the YAML manifest.
+# The sibling mutations.py dedents by four because its anchors are copied out of the
+# ConfigMap block scalar; these are copied out of the script as `python3 -` sees it,
+# which is one less transformation to get wrong. check.sh passes the extracted file,
+# so what is proven falsifiable is byte-for-byte what runs on the cluster either way.

+# Runtime is ~85s serial (one subprocess per mutation, each running the full selftest
+# against an in-process stub Keycloak; no network, no cluster). The selftests run in a

+#
+# THE BUG CLASS THIS CLOSES. PiHole's LoadBalancer frontends are the only thing stopping it being
+# an open resolver, and their `loadBalancerSourceRanges` is pulled in two opposite directions:
+#   * Too WIDE, and the resolver is open: a public range, or 0.0.0.0/0, in this list is the whole
+#     restriction gone, with nothing else in the path to catch it (the CiliumNetworkPolicy admits
+#     `world` on :53, because that is the only peer that can describe post-LoadBalancer traffic).
+#   * Too NARROW, and VPN DNS dies: wg0 is a Cilium kube-proxy-replacement device, so a tunnel
+#     client's query is load-balanced with its 10.90.0.x source intact, ahead of the iptables
+#     MASQUERADE. A LAN-only list is predicted to drop it as DROP_NOT_IN_SRC_RANGE, and the
+#     tunnel would still report a healthy handshake.
+#
+# GIVEN the repository as git tracks it,
+# WHEN  every type=LoadBalancer Service in namespace `pihole` is collected and each source range
+#       is resolved through cluster-vars (base value AND the prod overlay's replacement),
+# THEN  (1) the frontends exist and cover both udp/53 and tcp/53;
+#       (2) every frontend lists ${LAN_CIDR} and ${WG_CLIENT_CIDR};
+#       (3) every range resolves to a valid IPv4 CIDR inside RFC1918 — so no 0.0.0.0/0, no public
+#           range, and no unresolvable token that could hide one;
+#   AND (4) the check is NON-VACUOUS: a real checkout and a floor on the assertion count.
+#
+# WHAT THIS DOES NOT PROVE: that a query over the tunnel is actually answered. That needs a
+# handshake from a real client; see platform/vpn-ingress/README.md.

+branch: feat/pm-agent-registry-pull-secret
+title: The kubelet's pull credential — the second half of making agent-runner pullable, and the seventh field the admission policy had not read
+---
+
+## What changed
+
+The registry had two blockers. The first — the nodes resolving the registry hostname to the
+non-hairpinned WAN and failing TLS against the router's `CN=%D` certificate — was diagnosed
+and fixed by an `/etc/hosts` pin, merged in #59 and applied by the operator. This is the
+second: **the pull is unauthenticated, and this registry refuses unauthenticated clients
+outright.**
+
+`pm-agent-registry` is a new `kubernetes.io/dockerconfigjson` Secret, SOPS-encrypted with
+placeholder values, referenced by `imagePullSecrets` on both the dispatcher Deployment and
+the committed worker Job template. It is a **second Secret holding the same Gitea token** as
+`pm-agent-credentials`, because the two consumers need two formats: the application reads a
+raw token from env, the kubelet reads a dockerconfigjson before any container starts. That
+duplication is the established pattern here (the Keycloak client secret is mirrored the same
+way, for the same reason) and it is documented in both `.example` files.
+
+The operator's part is the value, and one scope: the Gitea token must now carry
+**`read:package`** alongside `write:repository` and `write:issue`. Steps are in
+`platform/pm-agent/pm-agent-registry.sops.yaml.example`, including the trap that
+`.dockerconfigjson`'s registry key must be the bare host as the image reference spells it —
+with a scheme or a port it matches nothing, the kubelet pulls anonymously, and the failure is
+indistinguishable from the Secret being absent.
+
+**The admission policy gained a seventh rule.** `imagePullSecrets` is a pod-spec field that
+no container references, which is exactly why it is easy to leave unread — the same shape of
+omission as `initContainers`, `ephemeralContainers`, `env` and `envFrom` before it. The
+kubelet reads the named Secret, in this namespace, before anything runs. Rule 1's pattern now
+REQUIRES the committed entry and rule 7 forbids any other or any second one; both halves are
+needed because a `foreach` over an absent list yields no result.
+
+The leverage is small and worth saying so: the image is digest-pinned, so a different pull
+credential cannot change *what* runs, and the only Secrets in this namespace are the agent's
+own. It is pinned anyway, because "only the committed shape" is this policy's whole premise
+and the rule costs four lines.
+
+## What I verified
+
+- **`kyverno test platform/kyverno/tests/pm-agent` → 33 passed, 0 failed** under the pinned
+  CLI (was 28 before this change). Three new fixtures, each a real path rather than a style
+  violation: `extra-pull-secret` (the committed entry PLUS a second one — rule 1's array
+  pattern is satisfied by the first element, which is why the count is asserted separately),
+  `wrong-pull-secret` (a different Secret in this namespace), and `no-pull-secret` (absent
+  entirely, refused by rule 1's pattern because rule 7's foreach cannot see it).
+- **`PM_SELFTEST=1 pm-dispatch` → exit 0**, now also asserting that the committed Job
+  template names exactly `pm-agent-registry` — so the template and the policy cannot drift
+  apart without the image build failing.
+- **`./ci/gate.sh` in the pinned toolbox, from a §0 worktree → exit 3 (UNDETERMINED)**, with
+  `gitea-settings` the only stage that did not run (no `SETTINGS_API_TOKEN` on this
+  workstation). Every other stage green, `spec-immutability` included. rc 3 is not a pass.
+- **The gate caught me shipping the Secret in plaintext.** I wrote the placeholder
+  `pm-agent-registry.sops.yaml` and never ran `sops -e -i` on it. `no-plaintext-secrets`
+  refused it with both halves named — "has no top-level `sops:` block with a mac" and
+  "Secret value '.dockerconfigjson' is not SOPS ciphertext" — which is exactly the check
+  earning its place: the file looked finished, and the value was a placeholder, so nothing
+  about reading the diff would have made it obvious. Encrypted, and the stage is green.
+- **The registry really does refuse anonymous clients**, measured before building this
+  (2026-10-05): the anonymous registry token's `access` claim is `null`, every `/v2/…`
+  path answers 401 whether it exists or not, and `/api/v1/packages/Home-Network` replies
+  `{"message":"token is required"}`. That is why this is a credential and not a posture
+  tweak.
+
+## What I did NOT verify
+
+- **That the pull now works.** Nothing has been pushed to that registry and the committed
+  digest is still the all-zero placeholder, so neither half of the registry fix has been
+  exercised end to end. The first real pull is what proves both at once — and if it fails, the
+  error names which half: `x509 … not valid for any names` is the resolution pin, `401` /
+  `unauthorized` is this credential.
+- **That the `/etc/hosts` pin from #59 took effect.** The operator applied it; I could not
+  confirm the effect, because the dispatcher pod's retained events are all repeating
+  `BackOff` with no fresh `Pulling`, so the `x509` message still visible is the one from
+  before the play ran. Not evidence either way.
+- **Whether `read:package` is sufficient** for a pull from a Gitea package of this type. It is
+  the documented read scope for packages; nothing here has exercised it, because no package
+  exists yet.
+- **The dockerconfigjson placeholder is not a valid credential and is not meant to be.** Its
+  `auth` field is a `REPLACE-ME` string rather than base64, so a pull with it will fail at
+  authentication rather than be mistaken for working.
+- **Anything about runtime.** Unchanged from the previous entries: the image has never been
+  built or pushed, no dispatcher has authenticated to Gitea, no issue has been triaged, no
+  worker Job has ever been created, and the admission policy — live, `Enforce`, now seven
+  rules — has still never admitted or refused a real Job.
+
+**Addendum 2026-10-30 (rebased onto #81/#82/#83; see `decisions/2026-10-30-pm-agent-live.md`).**
+Three statements above are now out of date, and one was wrong when written:
+- *"Nothing has been pushed to that registry"* — no longer true. CI published agent-runner in
+  images run 340 (`sha-523cd9118f95` = `main`, digest `sha256:c4eba5b3…6eb42`), and this
+  branch now pins it.
+- *"That the `/etc/hosts` pin from #59 took effect"* — now measured: all three prod nodes
+  carry the line, resolve the name to `192.168.2.20`, and get `401` with `ssl_verify_result=0`
+  from `https://gitea.home.keithjackson.dev/v2/` (see the new entry).
+- *"Whether `read:package` is sufficient"* — the scope is necessary but not the whole answer:
+  org-package access is decided by account permission (team Packages unit, or org
+  visibility). Handled in the registry `.example`.
+- **Wrong when written:** the scope list. Gitea 1.24.3 puts `GET /api/v1/user` — the
+  dispatcher's first call — behind the `user` scope category, so a token with only
+  `write:repository`, `write:issue` and `read:package` CrashLoops the dispatcher on startup.
+  The token needs `read:user` too.

+title: "Make the passkey realm config converge via GitOps — policy, enrolment action and the browser flow, the flow blue/green so the bound login path is never mutated"
+---
+
+## What changed
+
+**Why this is a new branch and not an update to PR #72.** The brief for this work said to extend
+PR #72 (`feat/keycloak-passkeys`) in place and not open a new PR. That premise was already stale
+when I started: **PR #72 merged at 2026-10-18T05:44:04Z** (Gitea API: `state: closed`,
+`merged: true`, `merge_commit_sha: 4d489f2`), and `git log origin/main` carries
+`4d489f2 Merge pull request '…' (#72)`. A merged PR cannot be updated, and CLAUDE.md §1 leaves
+exactly one path to `main`. So this is a fresh branch from `origin/main` in its own worktree, and a
+new PR. For the same reason this is a **new** `decisions/` entry rather than an edit to
+`decisions/2026-10-17-keycloak-passkeys.md`, which is now merged history describing a different unit
+of work; it is the entry to read first for the passkey *design* decisions, which are not repeated
+here.
+
+**The problem.** PR #72 declared the WebAuthn passwordless policy and a restructured `browser-mfa`
+flow in `platform/keycloak/keycloak-realm-import.yaml`. That declaration **could not take effect**.
+A `KeycloakRealmImport` is a one-shot; prod's reads `Done=True / Started=False / HasErrors=False`,
+so the operator will never re-run it and every realm-level field or flow declared after the first
+import is inert — in git, applied by Flux, reported Ready, reaching the realm never. Merging it
+changed nothing about how anyone logs in, and nothing anywhere said so. Same failure class as the
+2026-09-06 client-secret incident, third field over.
+
+**What now makes it converge.** A **sibling** reconciler, modelled on
+`platform/keycloak/client-secret-reconciler.yaml`:
+
+- `platform/keycloak/passkey-reconciler.yaml` — ConfigMap (Python, stdlib only, **zero dollar
+  signs**) + CronJob on `*/15 * * * *`, `automountServiceAccountToken: false`, admin credential by
+  `secretKeyRef` only. Three passes, **all of which converge**:
+  1. **WebAuthn passwordless policy.** Strict read-modify-write of `GET`/`PUT /admin/realms/homelab`,
+     changing only the `webAuthnPolicyPasswordless*` keys that differ, readback-verified.
+  2. **`webauthn-register-passwordless` required action.** Strict read-modify-write of one
+     **literally-named** alias; converges `enabled: true` / `defaultAction: false` only.
+  3. **The browser authentication flow — BLUE/GREEN.** Build the declared tree under a new, unused
+     alias; verify it by readback; flip `browserFlow` in **one atomic PUT**.
+- `ci/render-keycloak-passkey-policy.py` + the **generated**
+  `platform/keycloak/passkey-desired-state.yaml` — the desired state, rendered from the realm
+  import, `--check`ed by the merge gate.
+- `conformance/tests/l0-static/keycloak-passkey-reconciler/` — `check.sh`, `chainsaw-test.yaml`
+  (`scope: whole-repo`), `mutations.py`.
+- `platform-config/kustomization.yaml` — both new resources, in the **same** Kustomization as the
+  realm import.
+- `platform/keycloak/README.md` — the layout table, the section heading, and the "does NOT reach the
+  live realm" section rewritten: all three declared things now converge, with the blue/green
+  mechanics, the rollback command and the `--no-bind` fallback written out.
+
+### The flow design was reconsidered, and the first version of it was wrong
+
+**This is worth recording because the superseded reasoning was not silly, it was just wrongly
+scoped.** The first design of pass 3 was **audit-only**: compare the live browser flow against git,
+report divergence loudly, and never write it — leaving the restructure as a one-time admin-console
+action. The reasoning was that converging a five-flow / ten-execution tree needs create-subflow,
+create-execution, set-requirement and bind-config as *separate* untransacted admin-API calls, so a
+run dying between them leaves a **half-built flow bound as the login path** for every SSO-gated app
+*and* kubectl — and this repo has had a total SSO outage from a realm change (2026-09-06), with the
+conditional-OTP sub-flow (which the declared structure moves one level deeper) once 403ing every
+platform-admin.
+
+**That risk analysis was sound but it assumed the wrong shape.** It is true only if you mutate the
+*bound* flow. The operator's instruction was *"if this can be done through GitOps, it should"*, and
+audit-only did not meet it — a manual admin-console step is exactly what the one-shot import already
+forces. So:
+
+- All the multi-call construction happens on a flow **nothing is using** (the declared alias plus a
+  hash of the desired shape, applied to *every* alias in the tree — reusing `browser-mfa-forms`
+  would mean writing *into* the bound tree). A failure at any point leaves an orphaned, unbound flow
+  and **zero user-visible effect**. The untransacted-calls problem dissolves.
+- The built flow is **read back and verified** — nesting levels, ordering, authenticators,
+  requirements, and the conditional-OTP config *contents* — **before** anything is bound. The
+  regression the operator feared is now caught *before* it can bite rather than after.
+- The flip is **one atomic PUT** of the realm setting `browserFlow`.
+- **Rollback is one write.** The previous alias is printed in the run log, and there is **no
+  `DELETE` anywhere in the allow-list**, so the old flow survives as a working rollback target.
+
+**The new safety property, enforced structurally rather than by intention.** Blue/green needs
+flow-create and execution-add endpoints, which widens the allow-list — and the allow-list alone
+cannot express "but not the flow that is bound", because its write entries are alias-parameterised.
+So a second guard sits at the same choke point in `_http()`: the live `browserFlow` alias and its
+**entire subtree** of sub-flow aliases and execution ids are read first, and every write is screened
+against those sets before a socket opens. Protecting the whole subtree matters — adding an execution
+to `browser-mfa-forms` changes live login behaviour just as surely as touching `browser-mfa`. It is
+**fail-closed**: the sets start each run as "not determined", and while they are, *every* flow write
+is refused; if the bound flow's executions cannot be read they stay undetermined and the flow pass
+writes nothing.
+
+**Idempotence became load-bearing rather than merely nice.** A rebuild-and-reflip every 15 minutes
+would churn the login path on a schedule, so the bound flow is compared *structurally* and a match
+produces **zero writes and no new flow**. Sub-flow and config *aliases* are deliberately not
+compared: a flow this program built carries a hash suffix, so comparing labels would make it
+permanently unrecognisable as converged. A crashed run's completed-but-unbound flow is **reused**; a
+half-built one is left alone and the next candidate alias is used, with the candidate count
+**bounded** so a persistently failing build fails loudly instead of creating unbounded sprawl.
+
+**Where the rollback target is recorded, and why not as an annotation.** The brief suggested
+recording the previous `browserFlow` alias as an annotation on the CronJob or in a ConfigMap. The
+pod **cannot**: it runs with `automountServiceAccountToken: false` and has no Kubernetes API access
+at all, which is the same property that made the mounted-generated-ConfigMap design preferable to
+reading the CR (and is why this change adds no `**/rbac.yaml`). Giving it write access to its own
+annotations would trade a narrow, gate-verified read for a Kubernetes API writer, which is a worse
+bargain than the one it would buy.
+
+So the record is in two places that cost nothing: the **run log** prints
+`ROLLBACK is one write: set browserFlow back to <alias>. The old flow was NOT deleted.`, and — more
+durably — **the realm itself**, because nothing is ever deleted. Every superseded flow is still
+listed under `Authentication -> Flows`, so the rollback target is discoverable from the admin console
+even if every Job log has rotated away. The README carries the rollback procedure.
+
+**I achieved full convergence including the bind.** `--no-bind` exists as the deliberate fallback
+(build and verify, leave the flip as a one-write human act) but it is not the default and was not
+needed.
+
+**No `**/rbac.yaml` was touched.** The brief floated having the reconciler read the
+`KeycloakRealmImport` CR from the Kubernetes API, which would need a Role, a RoleBinding and a
+ServiceAccount token. I rejected that for the narrower, already-proven pattern: a desired state
+**generated** from the import and **mounted**, so the pod keeps `automountServiceAccountToken:
+false` and no Kubernetes API access at all. Skew is prevented by the gate running the renderer with
+`--check`, not by a second declaration being trusted.
+
+**Sensitive paths touched** — checked against `infra/gitea/approval-policy.json` rather than from
+memory, which caught one I had initially missed. **Three**:
+
+| Path | Why it is in the policy | What I changed |
+|---|---|---|
+| `ci/**` | the pipeline itself | added `ci/render-keycloak-passkey-policy.py` |
+| `conformance/**` | changing the tests changes what green *means* | added the L0 test directory |
+| `platform-config/kustomization.yaml` | Flux wiring / which manifests are actually applied | added the two new resources |
+
+**Not** touched: `**/rbac.yaml`, `clusters/**`, `platform/kyverno/**`, `.gitea/**`, `bootstrap/**`,
+`infra/gitea/**`, `.sops.yaml`, any `*.sops.yaml`, `CLAUDE.md`.
+
+So this PR **requires an approving review from someone who is not its author**, and
+`ci/approval-policy.sh` is fail-closed, so it will block until that exists. I did **not** post
+`/approve-override` — CLAUDE.md §1 names doing that on your own agent PR as exactly the
+self-approval the stage exists to prevent. The operator needs to either review it or post the
+override.
+
+## What I verified
+
+**Measured against the live cluster** (read-only `kubectl --context k3s-prod`):
+
+- `keycloakrealmimport homelab`: `Done=True Started=False HasErrors=False` — the import is a
+  completed one-shot. **This is the premise of the whole change and it is measured, not assumed.**
+- Keycloak image actually running: `quay.io/keycloak/keycloak:26.0.6`.
+- `kustomization/platform-config` `.status.lastAppliedRevision` ==
+  `gitrepository/flux-system` artifact revision == `main@sha1:83d3568…`, which contains the PR #72
+  merge. So the inert declaration is genuinely applied and genuinely inert.
+
+**`PUT /admin/realms/{realm}` does not touch users, groups, clients or roles in 26.0.6** —
+established from source at tag `26.0.6`, not from documentation or memory:
+
+- `RealmAdminResource.updateRealm` is the only handler. Its javadoc: *"Any user, roles or client
+  information in the representation will be ignored. This will only update top-level attributes of
+  the realm."*
+- It delegates to `RepresentationToModel.updateRealm` →
+  `DefaultExportImportManager.updateRealm` (`model/storage-private/.../datastore/`), **lines
+  725–894**. I brace-matched that body and enumerated every `rep.getX()` call in it: it contains
+  **no** `getUsers()`, `getClients()`, `getGroups()`, `getRoles()`, `getRequiredActions()`,
+  `getAuthenticationFlows()` or `getAuthenticatorConfig()`. Those objects are **unreachable** from
+  the endpoint, not merely ignored by convention.
+- Two findings that changed the design, both from the same read:
+  - `updateRealm` **does** read `rep.getBrowserFlow()`, so the endpoint can rebind the realm's login
+    path. The write therefore carries `browserFlow` straight back from the GET and a hard assertion
+    refuses the PUT if it would differ.
+  - The passwordless policy is applied **all-or-nothing and only when `RpEntityName` is non-empty**
+    (line 842), and `getWebAuthnPolicyPasswordless(rep)` substitutes a **Keycloak default** for every
+    null field (line 1253ff). A partial PUT would therefore silently reset every key it omitted, and
+    one missing `RpEntityName` would drop the whole policy while returning 204. This is why the write
+    is a strict read-modify-write of the full live representation.
+- `AuthenticationManagementResource.updateRequiredAction` (line 1205) is **per-alias** and likewise
+  **replaces** the provider from the representation (name, alias, priority, enabled, defaultAction,
+  config), and 404s when the alias is unregistered. Hence read-modify-write there too.
+- `DefaultRequiredActions` registers `webauthn-register-passwordless` with `enabled=true`,
+  `defaultAction=false`, `priority=80` — confirming the realm import's claim that declaring it would
+  restate a default while deleting ten siblings.
+- **The realm GET really does return what the read-modify-write needs.** This is load-bearing: if
+  the GET omitted the passwordless keys, the PUT body would be missing them and 26.0.6 would reset
+  them to defaults. `ModelToRepresentation.toRepresentation` (lines 471–482) sets **all ten**
+  `webAuthnPolicyPasswordless*` fields plus `ExtraOrigins`, and line 496 sets `browserFlow`. I
+  checked for an `internal`/`export` guard around that block — there is none in lines 380–500, so
+  those fields are emitted unconditionally, not only on the export path.
+
+**The five flow-construction endpoints, read from 26.0.6 source before being used:**
+
+- `POST /authentication/flows` — `AuthenticationManagementResource.createFlow`, rejects a duplicate
+  alias. Carries **no alias in its path** (the alias is in the body), which is why it needed its own
+  body-based screen; without that it escaped the protected-subtree guard entirely. My selftest
+  caught that, not my reading.
+- `POST /flows/{alias}/executions/flow` — `addExecutionFlow`, body `{alias, type, description}`.
+  Creates the sub-flow **at requirement DISABLED**, and refuses if the parent `isBuiltIn()`.
+- `POST /flows/{alias}/executions/execution` — `addExecutionToFlow`, body `{provider}`. Also
+  DISABLED unless the factory has exactly one requirement choice. Both assign `getNextPriority()`,
+  so **insertion order is the resulting order** — which is why the builder inserts depth-first in
+  declared order and then verifies by readback.
+- `PUT /flows/{alias}/executions` — `updateExecutions`. **A trap I would have walked into:** it
+  compares `rep.getPriority()` against the stored priority, and a JSON body omitting `priority`
+  deserialises it as the int **0** — which would silently **reshuffle the whole execution order**
+  while only a requirement change was intended. Every requirement write therefore carries the
+  execution's current priority back. There is a mutation for it and a selftest assertion on the
+  resulting order.
+- `POST /executions/{id}/config` — `newExecutionConfig`, creates an authenticator config and binds
+  it. Config aliases are suffixed like flow aliases, because 26.0.6 keeps them unique per realm and
+  the old flow already uses the declared alias.
+
+**Offline proofs, all green:**
+
+- The reconciler's `--selftest`, **extracted from the shipped ConfigMap** and run: **216 assertions
+  pass**. Its stub Keycloak models the 26.0.6 behaviours that bite — the RpEntityName gate, the
+  all-or-nothing policy rebuild, the required-action replace, the `updateExecutions` priority trap,
+  and flow construction where everything is created DISABLED — so these are tested against the real
+  semantics rather than a forgiving fake.
+- **A build killed at four different points (after 1, 3, 6 and 9 construction writes) never binds
+  and never touches the live flow.** Each case asserts the realm is still bound to the old alias,
+  that no write targeted the bound subtree, and that every live flow survives. This is the assertion
+  that makes blue/green a property rather than a claim.
+- **Verify-before-bind is exercised, not assumed.** Two stub sabotages — a server that accepts the
+  requirement writes and applies the wrong value, and one that writes the conditional-OTP role under
+  `condition.evaluated.user.role` — both end with the flow **built but NOT bound** and the old flow
+  still live.
+- `mutations.py`: **all 30 injected regressions caught**, including the six that are the blue/green
+  safety argument itself (build into the bound flow; never call the screen; reset the protected sets
+  to empty; bind before verify; report a failed build as success; reuse an existing flow without
+  verifying it).
+- Mutation testing again found real gaps in my own work, which I fixed rather than weakening the
+  mutations. Across the two designs: no readback coverage on the realm write, no coverage of an
+  undeclared policy key surviving, a mis-indented anchor, and — in this design — **no coverage at
+  all of the bound flow being unreadable**, which is the fail-closed path. It also showed me that
+  **two of my proposed mutations were not real regressions**: the module-level initial value of the
+  protected sets is dead code (`run()` resets them first), and removing the early return after a
+  build failure is covered by verify-before-bind anyway. I re-anchored both onto the properties that
+  *are* load-bearing rather than pretending the originals had been caught.
+- The new L0 `check.sh`: rc 0, all assertions. It asserts the renderer `--check`; that the realm
+  import and the desired state are rendered by the **same** Flux Kustomization; that the renderer's
+  and reconciler's writable key tuples are identical (parsed out of both sources with `ast`); that
+  `defaultAction` is `false`; that the realm import declares **no** `requiredActions` block
+  (previously only a comment saying "DO NOT ADD ONE"); that the **sibling** reconciler's allow-list
+  was not widened; that **nothing is deletable** and the execution-/config-id-scoped write endpoints
+  stay off the list (they carry no flow alias, so they could not be screened); and — the
+  load-bearing one — that the **protected-subtree guard exists in the source, is wired into
+  `_http()`, resets to "undetermined" every run, screens the body-only create-flow endpoint, and
+  that the policy write still refuses to rebind `browserFlow`**.
+- `ci/render-keycloak-passkey-policy.py --write` output round-trips: the generated JSON is accepted
+  by the reconciler's `declared()`, its 10 policy keys equal the reconciler's `POLICY_FIELDS`, and
+  it flattens to the exact 11-step tree the realm import declares, with
+  `conditional-otp-platform-admin` bound at level 4.
+- `${BASE_DOMAIN}` is carried into the generated ConfigMap **verbatim**, and both files sit in
+  `platform-config`, so one substitution pass decides the RP ID.
+- Zero dollar signs in the reconciler script (the Flux envsubst trap), verified on the committed
+  manifest.
+
+**The conditional-OTP regression is detectable — and now also preventable.** The comparison is
+key-by-key on the authenticator config contents, and because it runs **before** the bind, a flow
+carrying the bug never becomes the live login path. `--selftest` covers it three ways: the historical
+`condition.evaluated.user.role` key injected into a *built* flow (built, verified, **not bound**,
+old flow still live); the same bug already live in the *bound* flow (reported, then **fixed** by
+building and binding a correct flow); and the config disappearing entirely. `mutations.py` deletes
+the comparison and the undeclared-key report and requires the selftest to notice both. The suite
+also covers a requirement flipped from `ALTERNATIVE` to `REQUIRED`, the un-restructured legacy flow,
+a correct-but-unbound flow, and a cyclic declaration.
+
+**Gate:** see the gate section of the PR / the run quoted in my report — rc and per-stage results
+are recorded there rather than paraphrased here.
+
+## What I did NOT verify
+
+- **The live realm's actual passkey state is entirely UNVERIFIED.** I never authenticated to the
+  Keycloak admin API. Doing so needs the `keycloak-admin-credentials` password, which CLAUDE.md §6
+  forbids decrypting or printing, so I did not read the realm's current
+  `webAuthnPolicyPasswordless*` values, its required-action list, or its `browser-mfa` executions. I
+  therefore **do not know** how much drift the first real run will report, nor that the live flow is
+  in the "legacy shape" my selftest models — only that the import never re-ran, which makes drift
+  the overwhelmingly likely state. The first run's log is the measurement, and nobody has seen one.
+- **Nothing has ever run against a real Keycloak.** Every behavioural proof is against an
+  in-process stub I wrote, and a stub I wrote cannot falsify my own reading of the source. This
+  matters more for the blue/green flow builder than for anything else in the change, because it is
+  **five endpoints I have never exercised**. Specifically unproven in reality:
+  - That `POST /flows/{alias}/executions/flow` and `.../executions/execution` accept the bodies I
+    send and assign priorities in insertion order. If they do not, the build produces a tree that
+    fails verification — which is the safe failure (nothing is bound, login unaffected), but it
+    means **the flow would never converge** and the Job would fail every 15 minutes.
+  - That `PUT /admin/realms/homelab` accepts a full round-tripped representation. The analogous
+    *client* endpoint rejects one with `400 "Cannot parse the JSON"` (measured 2026-09-06), and the
+    sibling reconciler's whole minimal-PUT rule exists because of it. The source says the realm
+    endpoint differs; no measurement here confirms it. **If it does not, both the policy pass and
+    the atomic bind fail closed** — loudly, writing nothing.
+  - The exact JSON shapes compared: `AcceptableAaguids` as `[]` rather than absent or null,
+    `CreateTimeout` as a JSON int, `RequireResidentKey` as the literal string `"Yes"`. A shape I did
+    not anticipate would show up as **perpetual drift** — a write every 15 minutes that never
+    converges — rather than as an error.
+  - That `authenticationConfig` on an execution-info response is the config **id** (I read it from
+    the representation class, but never saw a live response).
+- **I did not verify the alias-collision behaviour against a real realm.** The recovery logic
+  assumes `POST /flows` returns a non-2xx on a duplicate alias (the source checks
+  `getFlowByAlias != null` and raises `ErrorResponse.exists`), and that a config alias collision
+  likewise fails. If either silently succeeded, the recovery path would behave differently than
+  modelled.
+- **Flow sprawl is bounded but real.** Every genuinely new desired shape creates a new flow and
+  **nothing is ever deleted** — by design, because the old flow is the rollback target. Over many
+  shape changes the realm accumulates unbound flows. There is no cleanup, automated or documented
+  beyond "an operator deletes them". I consider that the right trade (deletion is the one operation
+  that could destroy a rollback target) but it is a cost, not a non-issue.
+- **No L2 behavioural test was added.** The reconciler has an `--audit` mode built for one and the
+  sibling has `tests/l2-behavioral/keycloak-client-secrets-match-git`, but I added no equivalent.
+  And `vars.CLUSTER_AVAILABLE` is unset, so L2/L3 would not run in CI anyway. **CI proves the
+  offline subset only; it proves nothing about the live realm.**
+- **No alerting.** Unlike the first design there is no longer any failure that is "expected by
+  design", so a PrometheusRule on `kube_job_status_failed` would now be meaningful — and I did not
+  add one. A silently failing CronJob (image pull failure, rotated admin password, changed Secret
+  key) is visible only to someone who looks at Jobs. This is a real gap, not a resolved one.
+- **That passkey login works.** No passkey has been enrolled and no browser has been pointed at
+  this. Nothing offline can prove a WebAuthn ceremony completes, that the `ALTERNATIVE` fork
+  degrades to the password form via `CREDENTIAL_SETUP_REQUIRED`, or that a platform-admin is still
+  asked for TOTP on the password branch. The README's four-step manual check remains the only thing
+  that would establish it, and it remains undone.
+- **That the RP ID is right for the origin.** `${BASE_DOMAIN}` is a legal registrable-domain suffix
+  of `keycloak.${BASE_DOMAIN}` on paper, but a wrong RP ID fails **in the browser**, before Keycloak
+  is involved, with no server-side log line. The reconciler will happily converge the realm on a
+  wrong RP ID; it checks that git and the realm agree, never that git is correct.
+- **The first real run will change how everyone logs in.** Once this merges and Flux applies it, the
+  next tick builds a flow and — if it verifies — **flips the realm's browser flow**. The UX change
+  is deliberate and documented (username screen, then password), but it is the first time it will
+  have happened, unattended, on a schedule. The rollback is one write and the old flow survives;
+  that is the mitigation, and it has not been rehearsed either.
+- **CI's own result.** My gate run is local. `gitea-settings` cannot run locally, and
+  `ci/approval-policy.sh` reports green N/A offline while this branch touches three sensitive paths,
+  so **the PR is guaranteed to need a non-author approving review** and I have not seen CI report. I
+  did not and will not post `/approve-override` on my own PR.
+- I re-measured branch protection this session (`protected: true`, `user_can_push: false`,
+  `enable_status_check: true`, context `gate / gate (pull_request)`, `required_approvals: 0`), but
+  the branches endpoint does **not** expose `block_admin_merge_override`, so that row of CLAUDE.md
+  §2 is **not re-confirmed** by me.

+branch: fix/pihole-local-ttl
+title: "The split-horizon answer was uncacheable while the wrong answer cached for 5 minutes"
+---
+
+## What changed
+
+The operator reported DNS "flapping between the cluster ingress and the router (public IP)".
+PiHole was not at fault — both replicas answer correctly and consistently. The bug is an
+**asymmetry in cacheability** that we created.
+
+Measured on prod 2026-10-18:
+
+```
+dig home.keithjackson.dev @192.168.2.23 (pihole)  -> 192.168.2.20                TTL=0
+dig home.keithjackson.dev @1.1.1.1      (public)  -> wan.home.keithjackson.dev   TTL=300
+dig home.keithjackson.dev @192.168.2.1  (router)  -> wan....  TTL=153 -> 148 -> 143
+```
+
+dnsmasq answers `address=` entries with **TTL 0** unless told otherwise. The SOHO router forwards
+LAN queries to PiHole and **caches** the result — the decrementing TTL above is the proof it caches
+rather than forwarding live. So:
+
+* the **correct** answer is **uncacheable** (TTL 0): the router must re-query PiHole on *every*
+  lookup, which is maximum exposure to any momentary gap;
+* the **wrong** answer is **cacheable for 300s**: the instant the router falls back to its upstream
+  (standard forwarder behaviour when the forward target does not answer) it latches the public WAN
+  address and serves it to **every LAN client** for five minutes.
+
+So **one sub-second PiHole gap becomes five minutes of the whole house resolving to the WAN IP** —
+then it expires, the router re-queries PiHole, gets TTL 0 again, and is immediately re-exposed.
+That asymmetry, not the gap itself, is why this is visible as flapping rather than a blip.
+
+Fix: `local-ttl=60` prepended to `FTLCONF_misc_dnsmasq_lines` in `catalog/pihole.yaml`, so the
+private answer is cacheable and a short gap is invisible to clients. `apps/wave-0/pihole.yaml`
+regenerated with the canonical render command.
+
+## What I verified
+
+* **PiHole is NOT the fault.** Both replicas, queried directly by pod IP, answer `192.168.2.20`;
+  the VIP returned it 6/6; this workstation 8/8. DHCP hands out only `192.168.2.23`.
+* **The router caches rather than forwards live** — three successive queries returned TTL 153, 148,
+  143 (decrementing), which a pure forwarder could not do.
+* **The TTL asymmetry**, as quoted above: 0 from PiHole, 300 from public DNS.
+* **The router does answer DNS and returns the public chain** (`wan.home.keithjackson.dev` → the WAN
+  address), so a fallback always has a wrong answer available.
+* **`local-ttl` is the right directive**: dnsmasq applies it to replies made from configuration,
+  `/etc/hosts` and DHCP leases, which covers all five `address=` names with one directive. It is a
+  standalone option, not a sub-field of `address=`, so prepending it to the `;`-separated
+  `FTLCONF_misc_dnsmasq_lines` list is syntactically correct.
+* **The render is clean and scoped**: `catalog/render.py --all catalog -o apps --wave-layout
+  --no-image-automation` (the canonical command `ci/render-golden.sh` asserts against, and
+  deliberately **not** `--emit-waves`) changed exactly two files — `catalog/pihole.yaml` and
+  `apps/wave-0/pihole.yaml` — and the rendered diff is the single `local-ttl=60;` prefix.
+
+## What I did NOT verify
+
+* **UNAPPLIED.** Nothing has been reconciled, so I have not observed PiHole serving a non-zero TTL,
+  nor the router caching the private answer, nor the flap stopping. **Verify after merge with
+  `dig home.keithjackson.dev @192.168.2.23` (expect `TTL=60`, not 0) and then the same query at the
+  router (expect `192.168.2.20` with a decrementing TTL, not `wan.…`).**
+* **I did not confirm that PiHole/FTL accepts `local-ttl` via `FTLCONF_misc_dnsmasq_lines`.** The
+  directive is valid dnsmasq and the field is a passthrough, but `catalog/pihole.yaml`'s own header
+  records that FTL has previously written a bogus line into `dnsmasq.conf` and reported "0 invalid"
+  — so a malformed passthrough fails *silently*. If the TTL is still 0 after merge, that is the
+  cause, not this reasoning. Check the pod's `/etc/pihole/dnsmasq.conf`.
+* **60s is chosen, not derived.** Long enough for a pod restart and a lease re-election (both
+  seconds); it does **nothing** for an outage longer than the TTL, where the cache expires and the
+  public answer latches again. That is a real availability problem, not a caching one.
+* **This does not remove the trigger.** `192.168.2.23` is served by **two** LoadBalancer Services
+  (`pihole-dns-tcp`, `pihole-dns-udp`) with **two independently-elected L2 announcement leases**, so
+  two nodes can ARP for the same address at once — they sat on different nodes earlier the same day
+  (tcp on prod-2, udp on prod-1). The same pattern applies to crafty (`.22`) and unifi (`.21`).
+  Merging each pair into one mixed-protocol Service would remove the class; the operator has parked
+  that decision, and it is deliberately **not** in this change.
+* **Client-side bypasses are unexamined.** A device with its own resolver, or a browser with
+  DNS-over-HTTPS, bypasses PiHole entirely and always gets the public answer; this fix cannot help
+  there. Only this one workstation's resolver chain was inspected.
+* **No alert fires if the split-horizon answer regresses to the public address.** Nothing probes
+  `home.keithjackson.dev` from a LAN vantage point and compares it against `${GATEWAY_VIP}`, so the
+  next recurrence would again be found by a human noticing. That gap is not closed here.

+title: "The Renovate cron fired outside Renovate's own schedule, so it would never have opened a PR"
+---
+
+## What changed
+
+`.gitea/workflows/renovate.yaml` shipped (PR #73) with `cron: "15 3 * * *"`. **That schedule could
+never have produced a single PR.**
+
+Gitea Actions cron is **UTC**. `renovate.json` carries `"schedule": ["after 3am and before 6am"]`
+with `"timezone": "America/New_York"`, and that inner schedule is **authoritative** — Renovate
+re-checks it and declines to open PRs outside it. So:
+
+```
+cron 03:15 UTC  ->  23:15 EDT, the PREVIOUS EVENING in New York
+window          ->  03:00-06:00 local
+inside?         ->  NO (3h45m before the window opens)
+```
+
+The original comment claimed the cron was "slightly ahead of the repo window ... so a run is always
+in flight when the window opens". It is 3h45m *behind*, on the previous day. Every nightly run would
+have started, logged "not within schedule", opened **zero** PRs and exited **successfully** — a
+green tick forever, indistinguishable from "nothing needed updating". That is the same
+"failure-mode-is-a-green-tick" shape this repo keeps hitting, and it would have hidden the ~30
+pending updates PR #73 was written to surface.
+
+Changed to `cron: "15 8 * * *"`, chosen to survive DST rather than to be tidy. The window's UTC
+position moves:
+
+| | local window | in UTC |
+|---|---|---|
+| EDT (UTC-4, Mar–Nov) | 03:00–06:00 | 07:00–10:00 |
+| EST (UTC-5, Nov–Mar) | 03:00–06:00 | 08:00–11:00 |
+
+`08:15 UTC` is inside **both** (04:15 EDT / 03:15 EST), so no edit is needed at either switchover.
+A cron cannot follow DST, so this is the only way to get it right once.
+
+## What I verified
+
+* **The defect, by arithmetic rather than assertion:** `datetime(2026,10,18,03,15, UTC)` converted to
+  `America/New_York` via `zoneinfo` is `2026-10-17 23:15 EDT`; `3 <= hour < 6` is **False**.
+* **The fix, at both DST extremes:** `08:15 UTC` → `04:15 EDT` in July and `03:15 EST` in December,
+  both inside `03:00–06:00`. Computed, not reasoned.
+* **The inner schedule really is authoritative and really is set:** `renovate.json` on `main` carries
+  `timezone = America/New_York` and `schedule = ['after 3am and before 6am']`.
+* **`RENOVATE_TOKEN` now exists** as a repository Actions secret (listed by name via the Gitea API
+  alongside `SETTINGS_API_TOKEN`), so the workflow's fail-hard preflight will pass. It did not exist
+  when PR #73 was authored.
+* The edited workflow parses as YAML.
+
+## What I did NOT verify
+
+* **Renovate has still never executed.** This fixes *when* it runs, not *whether it works*. No run
+  has happened, so nothing here proves it extracts dependencies, authenticates to Gitea, or opens a
+  usable PR.
+* **`enabledManagers` may silently disable the custom managers — UNRESOLVED and the likelier
+  remaining bug.** `renovate.json` lists `enabledManagers: [..., 'regex', ...]` and defines
+  `customManagers` (correct modern key; `regexManagers` is absent, which is right). But modern
+  Renovate names the custom manager **`custom.regex`** in `enabledManagers`, not bare `regex`. If
+  the bare name is invalid or ignored, every inline `# renovate:` marker in the tree does nothing —
+  including the `external-snapshotter` `newTag` pin PR #73 flagged as probably inert. **I did not
+  change it**, because guessing at a config key that could fail validation and take the whole run
+  down is worse than leaving a question that one dry run answers definitively. The `dry_run: true`
+  dispatch log settles it: look for a per-manager dependency-extraction count, and for any config
+  validation warning naming `regex`.
+* **Whether a dry run inside vs outside the window differs usefully.** Renovate honours its schedule
+  even in dry-run, so a manual dispatch outside 03:00–06:00 local will also log "not within
+  schedule". That makes the first dispatch's output less informative than it looks; to see what
+  Renovate *would* do, either dispatch inside the local window or override the schedule for that
+  run. Not tested either way.
+* **No alert fires if the schedule stops firing.** PR #73 recorded this gap and it is still open: a
+  Renovate workflow that silently stops running (disabled Actions, expired token, deleted secret)
+  produces no signal at all. Closing it needs a check on last-successful-run age, which nothing
+  does.
+* No conformance test asserts the cron falls inside `renovate.json`'s window, so this exact bug can
+  return. A static check comparing the two is feasible and is not written.

+title: "renovate.json was invalid, so the first manual run errored out"
+---
+
+## What changed
+
+The operator ran the Renovate workflow manually and it **failed**. The cause is not the workflow:
+**`renovate.json` was never a valid Renovate config.**
+
+It carried five pseudo-comment keys — `_comment`, `_kubernetes_comment`, `_unmanageable_comment`,
+`_ignorePaths_comment`, `_docker_comment` — because JSON has no comments. Renovate **rejects unknown
+top-level options**, so the entire config failed validation. Proven with the official validator
+rather than inferred:
+
+```
+$ podman run --rm -v "$PWD/renovate.json:/tmp/renovate.json:ro,Z" \
+    ghcr.io/renovatebot/renovate renovate-config-validator /tmp/renovate.json
+ERROR: Found errors in configuration
+  Invalid configuration option: _comment
+  Invalid configuration option: _docker_comment
+  Invalid configuration option: _ignorePaths_comment
+  Invalid configuration option: _kubernetes_comment
+  Invalid configuration option: _unmanageable_comment
+```
+
+This is the second independent reason Renovate had never worked, on top of PR #77's cron firing
+outside `renovate.json`'s own schedule window. Either alone was sufficient to produce "nothing ever
+happens"; #73 shipped both.
+
+**Converted `renovate.json` → `renovate.json5`.** JSON5 permits real `//` comments, and Renovate
+discovers `renovate.json5` natively — nothing in `.gitea/` or `ci/` pins the old filename (only
+prose inside comments), and no `RENOVATE_CONFIG_FILE` is set. Every word of the original rationale
+is preserved as comments positioned next to what it explains, which a flattened `description`
+string would have lost.
+
+A header on the new file records the failure, the validator command, and the instruction to run it
+before committing — this class of bug is invisible to the repo's own gate.
+
+## What I verified
+
+* **The exact failure**, from the official validator, quoted above. Not read off a log, not inferred
+  from the workflow.
+* **The fix validates**: the same validator against `renovate.json5` returns
+  `INFO: Config validated successfully against 1 file(s)`.
+* **Nothing was dropped in the conversion**, checked programmatically against `git show
+  HEAD:renovate.json`: 18 non-comment keys before, 18 after, **no missing keys, no extra keys, and
+  no key whose value changed**. `docker: {enabled: true}` confirmed still present — the validator
+  prints a normalisation diff that mentions it, which is its own migration suggestion, not a
+  removal.
+* **74 comment lines survive** in the new file, so the rationale is intact.
+* **`RENOVATE_TOKEN` exists** as a repository Actions secret (listed by name via the Gitea API), so
+  the workflow's fail-hard preflight is satisfied.
+* **A suspicion was DISPROVED:** `enabledManagers` containing bare `regex` was thought to need to be
+  `custom.regex`, which would have silently disabled every inline `# renovate:` marker. The
+  validator accepts `regex`, so that concern was unfounded and nothing here changes it.
+* Nothing functionally references `renovate.json` by name — `grep -rn "renovate\.json" .gitea/ ci/
+  conformance/` returns only comment prose.
+
+## What I did NOT verify
+
+* **Renovate has still never completed a run.** This removes one of two blockers; PR #77 removes the
+  other. Neither is merged, so **no successful Renovate run has been observed** and I cannot say the
+  bot works — only that these two specific defects are fixed.
+* **I did not re-run the workflow after the fix.** The honest test is a `workflow_dispatch` with
+  `dry_run: true` once both this and #77 are merged. Expect ~30 dependencies behind, rate-limited to
+  `prHourlyLimit: 2` / `prConcurrentLimit: 5`.
+* **Whether the managers actually extract anything.** A valid config that matches no files is still
+  a no-op. The dry-run log's per-manager dependency counts are the only thing that proves the
+  `managerFilePatterns` are right, and I have not seen them.
+* **Whether `renovate.json5` is honoured by the pinned Renovate version in the workflow.** JSON5
+  discovery is long-standing and the validator accepted the file, but the workflow's image tag was
+  not cross-checked against the version that added it.
+* **Nothing in the gate catches an invalid Renovate config.** This bug would have recurred silently.
+  A one-line L0 check shelling out to `renovate-config-validator` would close it; it is not written
+  here, and `conformance/**` is a sensitive path.

+- gitea/act v0.261.2 `pkg/container/docker_run.go` `sanitizeConfig` drops **every** bind,
+  socket included, when `valid_volumes` is empty, which it is (the runner has no config file).
+
+Giving jobs the DinD daemon would have made every branch push root on the node, because that
+daemon is `privileged: true`.
+
+**The decision:** no job may reach a privileged daemon, and images are built by a **rootless
+BuildKit** daemon over mTLS. The runner (`apps/wave-1/gitea-actions.yaml`, DOCKER_HOST,
+valid_volumes) is **untouched**.
+
+- **`platform/buildkit/`** — a new hand-managed component in its own namespace `buildkit`. The
+  runner manifest is renderer-generated (`catalog/render.py` EXTRA_UNITS), and the builder has no
+  business sitting next to a privileged container. Flux reconciles it as the new Kustomization
+  `buildkit` (`clusters/base/buildkit.yaml`, `dependsOn: platform`).
+  - **Deployment:** `moby/buildkit:v0.34.1-rootless@sha256:f68752a5…0c4f89`, pinned by index
+    digest. The securityContext, every line measured (see *What I verified*):
+    - `privileged: false`;
+    - uid/gid 1000, `runAsNonRoot`;
+    - `capabilities: drop ALL, add SETUID, SETGID`;
+    - `allowPrivilegeEscalation: true`;
+    - `seccompProfile: Unconfined` and `appArmorProfile: Unconfined`;
+    - `readOnlyRootFilesystem: true`, with five emptyDirs.
+
+    Other settings:
+    - `--oci-worker-no-process-sandbox`;
+    - no ServiceAccount token;
+    - memory limit 4Gi, which covers build steps too;
+    - cache emptyDir with `sizeLimit: 6Gi`, and GC capped at 4 GB in `buildkitd.toml`
+      (ConfigMap).
+  - **mTLS via cert-manager** (`certificates.yaml`): a self-signed CA used only here, the server
+    cert `buildkitd-tls`, and the client cert `buildkit-client-ci`. buildkitd verifies every
+    client against that CA.
+  - **Service:** ClusterIP `buildkitd.buildkit.svc.cluster.local:1234`.
+  - **NetworkPolicies:**
+    - default-deny;
+    - ingress on 1234 **only from the act-runner pod** (`gitea-actions`,
+      `app.kubernetes.io/name=act-runner`);
+    - egress: DNS, world :443/:80 for downloads, and the `ingress` entity (the Gateway) for the
+      registry push.
+  - `versions.env`: the CI-side client, `buildx` v0.38.1 with the sha256 from its
+    `checksums.txt`, plus the address and certificate name CI dials.
+- **How DinD job containers appear to Cilium (measured, read-only).**
+  `iptables -t nat -S POSTROUTING` in the dind container shows
+  `-A POSTROUTING -s 172.18.0.0/16 ! -o br-… -j MASQUERADE` (and the same for docker0). So a job's
+  connection leaves with the **act-runner pod's IP, and therefore that pod's Cilium identity**.
+  That makes "only the act-runner pod" expressible and correct, but it cannot tell one job from
+  another, or a job from act_runner itself. Per-job authentication is the client certificate.
+- **Admission: no Kyverno exception needed.**
+  - Every ClusterPolicy actually applied (`platform-config/kustomization.yaml`; live:
+    `conformance-trigger-job-shape`, `label-cdi-worker-pods`, `pm-agent-job-shape`,
+    `require-auth-mode-label`, `require-default-deny-baseline`, `require-egress-class-label`,
+    `restrict-host-namespaces`, `secret-provenance`, `validate-default-deny-shape`) matches only
+    namespaces labelled `homelab.keithjackson.dev/app-namespace: "true"`, or only its own
+    namespace in the job-shape policies' case. `buildkit` carries no such label.
+  - There are no namespaced Kyverno Policies and no cluster-wide PSA default (both measured).
+  - The namespace is deliberately left without a PSA label, because PSS `baseline` forbids
+    `Unconfined` seccomp and AppArmor.
+  - `validate-default-deny-shape` does apply to the namespace's default-deny NetworkPolicy, and
+    its shape (both directions) satisfies it.
+- **Unprivileged user namespaces on the nodes (measured, read-only, via Ansible `sysctl`).** On
+  all three Debian 13.7 nodes, kernel `7.1.8+deb13-amd64`:
+  - `kernel.unprivileged_userns_clone = 1`;
+  - `user.max_user_namespaces = 127206`;
+  - no `kernel.apparmor_restrict_unprivileged_userns` (an Ubuntu-only key);
+  - AppArmor enabled (`Y`).
+
+  So this is a satisfied prerequisite, not an open one.
+- **The TLS conformance check needed a narrow, self-proving exception** (`conformance/**`, so this
+  changes what green means; flagged for the reviewer).
+  - The first gate run failed L0 `tls-lifecycle-automated` clause (5): "every Certificate's
+    issuer must be ACME". That is broader than the spec it serves:
+    - R-TLS-01 and docs/08 concern *externally reachable* services;
+    - ADR-0006 says "mTLS between workloads is a separate concern … not covered here";
+    - a public CA cannot issue for a `*.svc.cluster.local` name or a client-auth certificate.
+  - The new clause (5b) exempts a Certificate annotated
+    `homelab.keithjackson.dev/tls-scope: workload-mtls` **only if it proves it**:
+    - no Gateway listener serves its Secret;
+    - every DNS name and the commonName are a bare label or `*.svc[.cluster.local]`;
+    - it has no IP, URI or email SANs;
+    - its issuer is a namespaced `selfSigned`/`ca` Issuer in its own namespace;
+    - a `ca` issuer's Secret is produced by a likewise-exempt tracked Certificate.
+  - Exemptions are printed, and clause (9), the renewal arithmetic, still applies.
+  - **Negative-tested:** a public DNS name, and a Gateway serving `buildkitd-tls`, each fail the
+    check with a specific message.
+- **`infra/gitea/buildkit-client-secret.sh`** (operator action): copies `ca.crt`, `tls.crt` and
+  `tls.key` from the Secret `buildkit/buildkit-client-ci` into the Actions secrets `BUILDKIT_CA`,
+  `BUILDKIT_CLIENT_CERT` and `BUILDKIT_CLIENT_KEY`. Before writing anything it checks that:
+  - the cert verifies against the CA;
+  - the cert is a client-auth cert;
+  - the key matches the cert.
+
+  It never prints a value. `--check` reports whether the stored copy is older than the current
+  certificate.
+
+### Verification moved into the Containerfiles
+
+`docker run` cannot exist on BuildKit, so each Containerfile now names its shipped stage after the
+image (`toolbox`, `agent-runner`, `conformance-runner`) and ends in a **`verify` test stage**,
+`FROM <image> AS verify`. That stage runs every previous assertion at build time, as the image's
+non-root uid (65532 for agent-runner and conformance-runner), in `RUN --network=none`. It is never
+pushed.
+- **Every existing assertion is preserved**, and the toolbox gained one it never had: every tool
+  on PATH, and five tools report their pinned versions.
+- `probe-validation.sh` is `COPY`ed into the verify stage only, so it never ships.
+- **Bug fixed on the way:** in the old `docker run` block, `cmd | grep -q … && echo ok` and
+  `[ … ] && echo` could never fail the script under `set -e` + `pipefail`. The "entrypoints refuse
+  arguments", "not root", "no API key baked in" and "HOME writable" checks asserted nothing. They
+  are real assertions now.
+- **What a build step cannot reproduce, and how it is approximated** (also written in each stage's
+  header):
+  - **uid:** exact.
+  - **`--network none`:** exact, and each stage *proves* it. Its first check fails if DNS or a
+    TCP connection works. A negative control without `--network=none` fails that check.
+  - **`--read-only` rootfs:** not reproducible, because a RUN step always has a writable layer.
+    It is approximated by permission:
+    - `touch /should-fail` must fail;
+    - a `find / -xdev -writable ! -type l` inventory, run as the uid, must lie entirely under
+      `/workspace`, `/tmp` or `/var/tmp`. `! -type l` was needed: Fedora's `/usr/tmp` symlink
+      to `/var/tmp` tripped it.
+
+    The real control remains the pods' `readOnlyRootFilesystem`, which the admission policies
+    enforce.
+  - **`--tmpfs /workspace`:** approximated by the image's own `/workspace`, owned by 65532, which
+    is exactly what the pod's emptyDir replaces.
+
+  The opt-in `--verify-clone` still `run`s the image, so it remains local-only.
+- **`build-image.sh` (all three):**
+  - verify is `build --target verify` and the image is `build --target <image>`;
+  - a new `--print-build-args` prints the pins as `KEY=VALUE`, which is what CI consumes. The
+    arg list therefore exists once;
+  - the local podman path still works.
+- The L0 check `alert-rules-unit-tested` now looks for `"PROMTOOL_VERSION=$PROMTOOL_VERSION"` in
+  the toolbox's build-arg list.
+
+### The pipeline (`.gitea/workflows/images.yaml` + `scripts/images.sh`)
+
+- **The builder.** The driver downloads the pinned `buildx` and refuses a checksum mismatch. It
+  writes the client cert from the `BUILDKIT_*` secrets to a 0600 temp dir that is removed on exit,
+  creates a `remote` builder, and runs `buildx inspect --bootstrap`.
+- **It fails loudly, never skips.** It stops with a clear message if:
+  - the secrets are absent;
+  - buildkitd is unreachable. The message lists the causes in order: not deployed yet (Flux
+    applies it only after merge), stale certificate, NetworkPolicy.
+- **Pull request:** `buildx bake <image>-verify` for changed images. Nothing is pushed and no
+  registry credential is referenced. The `BUILDKIT_*` builder secrets *are* given to PR jobs,
+  because they must build.
+  - agent-runner is built FROM the toolbox built **in the same run** through a bake `target:`
+    context. That toolbox exists in no registry, so the toolbox is built as its base even when
+    its own inputs did not change.
+- **Push to main / dispatch on main:** for each image, the verify target first, and only then the
+  image itself with `push=true`. Tags are `sha-<12 hex>` (immutable) and `main` (moving).
+  - The digest is read back from the registry and compared with the client's metadata.
+  - agent-runner builds FROM the toolbox digest just pushed, or else from the pinned
+    `AGENT_BASE_IMAGE` (the zero placeholder bootstraps).
+  - `BUILDX_NO_DEFAULT_ATTESTATIONS=1` keeps one manifest per tag, which is what admission,
+    Renovate and the retention script assume.
+- **Unchanged from the first iteration:** change detection, publish idempotence,
+  `REGISTRY_PUSH_TOKEN` and its preflight, the Renovate markers, and `registry-retention.sh`. The
+  DinD prune step is gone, because nothing is built in DinD now.
+
+### Unchanged from the first iteration (still true)
+
+- **Digest references** carry `# renovate-digest: image=<repo> tag=main` markers:
+  - `platform/pm-agent/deployment.yaml` and `configmap.yaml`;
+  - `infra/agent/versions.env` `AGENT_BASE_IMAGE`, now the published toolbox by digest, zero
+    until the first publish;
+  - `conformance/versions.env` `CONFORMANCE_RUNNER_IMAGE_DIGEST`, which went from `""` to zero.
+
+  The admission policies are untouched.
+- **`renovate.json5`**:
+  - the `custom.regex` marker manager;
+  - `enabledManagers` `regex` → `custom.regex`;
+  - the `kubernetes` manager disabled for these three repos;
+  - `ignorePaths` narrowed so `conformance/versions.env` is visible.
+
+  `renovate.yaml` pins `renovate-version: 44.167.0` and adds a docker `RENOVATE_HOST_RULES` entry
+  using `RENOVATE_TOKEN`, which now needs `read:package`.
+- **`infra/gitea/registry-retention.sh`** (dry run by default; operator action); the
+  `conformance-trigger-kubeconfig.sh` precondition fix; and the docs (pm-agent README, runbook,
+  plan, conformance README, devcontainer README, workflows README). The docs are updated again
+  for BuildKit, and there is a new `platform/buildkit/README.md`.
+
+### Decisions and pushback
+
+- **The push credential is a PAT secret, `REGISTRY_PUSH_TOKEN`; the Actions token cannot push.**
+  Checked against Gitea **v1.24.3** source:
+  - `services/auth/basic.go` `Basic.Verify` turns a task token into the pseudo-user
+    `gitea-actions` (ID −2) and sets no token scope;
+  - `routers/api/packages/container/container.go` `Authenticate` (the `/v2/token` exchange every
+    docker client performs) requires `read:package`/`write:package`/`all` scope, so it answers
+    401. The Actions token cannot even *pull*;
+  - `services/context/package.go` `determineAccessMode` has `// TODO: ActionUser permission check`
+    and no branch for that user. Even past login it would get at most read on a public org;
+  - `models/repo/repo_unit.go` `ActionsConfig` has no token-permissions setting in 1.24.3.
+
+  The workflow fails loudly when the secret is absent, copying the `RENOVATE_TOKEN` preflight
+  pattern. With BuildKit the credential reaches the daemon through the buildx session (a
+  0600 `config.json` in the job's temp dir), never through the cluster.
+- **`regex` vs `custom.regex`: both work. Switched to the canonical `custom.regex`.** In Renovate:
+  - `lib/config/migrations/custom/enabled-managers-migration.ts` rewrites `regex` →
+    `custom.regex`;
+  - that migration runs on every repository run (`lib/workers/repository/init/merge.ts` →
+    `migrateAndValidate`), not only in the validator;
+  - `lib/modules/manager/index.ts` `getEnabledManagersList` accepts either spelling;
+  - `custom.regex` exists since 37.51.1 (renovatebot/renovate#24079).
+- **The open question hid a bigger bug: the Renovate config on main is invalid for the Renovate
+  the workflow actually runs.**
+  - `renovatebot/[email protected]` defaults `renovate-version` to `39`
+    (`action.yml`, `src/docker.ts`), which is 39.264.0.
+  - The validator used in #79 was `ghcr.io/renovatebot/renovate` with no tag, i.e. `latest`,
+    44.167.0.
+  - **Measured:** `renovate:39.264.0 renovate-config-validator` on main's `renovate.json5` gives
+    `ERROR: Found errors in configuration` with five errors, all `managerFilePatterns`.
+    `fileMatch` was renamed in 40.2.0.
+  - So once #80 fixes the filename, every run would still die at `CONFIG_VALIDATION`.
+  - Fixed by pinning `renovate-version: 44.167.0`. This branch's config validates clean on it.
+    The only `--strict` complaint is a pending migration of the pre-existing top-level
+    `"docker": {"enabled": true}` block, which I left alone.
+- **Unworkable as briefed: tracking the worker Job template's digest.**
+  - `infra/agent/worker-job-template.yaml` is `COPY`ed into agent-runner. A Renovate bump there
+    changes agent-runner's inputs, CI publishes a new digest, Renovate bumps it again, and so on
+    forever.
+  - `pm-dispatch` overwrites that field from `PM_WORKER_IMAGE` at runtime
+    (`pm-dispatch.py:649`), so nothing is lost by leaving it all-zero. It is commented as
+    deliberately untracked.
+  - For the same loop reason, `conformance/versions.env` is **not** an input of the
+    conformance-runner build, and a pipeline-only change does not republish on main.
+- **Changed from the brief: retention is a script, not a Gitea cleanup rule.**
+  - Gitea 1.24.3 has **no API** for cleanup rules (none in `routers/api/v1/api.go`; web
+    session+CSRF forms only, in `routers/web/web.go`). So a rule cannot be created, or
+    drift-asserted, as code. **`ci/gitea-settings.sh` was therefore not extended.** A cheaper
+    proxy (count versions per image) would need `read:package` on `SETTINGS_API_TOKEN`, which
+    it lacks.
+  - A built-in rule is also **unsafe here**. Gitea stores a manifest as a file of the TAG
+    version it was pushed under (`routers/api/packages/container/manifest.go`
+    `createPackageAndVersion`), and resolves a by-digest pull from those files
+    (`models/packages/container/search.go`). Deleting the tag a deployed digest was pushed under
+    breaks the `@sha256:` pull, and the rule's "newest N" knows nothing about what git pins. The
+    script keeps every digest git pins.
+- **Auto-merge.** Digest bumps of these images auto-merge on a green gate (the existing
+  `digest` rule). The exception is the conformance-runner bump: `conformance/versions.env` is a
+  sensitive path, so it waits for an administrator's `/approve-override` every time.
+
+## What I verified
+
+**Proved locally, against the exact pinned images:**
+
+- **Rootless buildkitd, configured as the manifest configures it.**
+  - Setup: the pinned `moby/buildkit:v0.34.1-rootless` digest, under rootless podman, with
+    `--cap-drop ALL --cap-add SETUID --cap-add SETGID`, seccomp unconfined and `--read-only`;
+    tmpfs at the same five paths; the ConfigMap's `buildkitd.toml`; mTLS on :1234.
+  - The image's `/etc/subuid` was overridden with `user:1:999` and `user:1001:64535`, because
+    rootless podman maps only 65,537 uids. rootlesskit's real `newuidmap` user-namespace path
+    still ran.
+  - It started, `buildctl debug workers` listed the OCI worker, and `debug workers -v` showed the
+    GC config applied (max 4.29 GB, reserved 1.07 GB).
+- **The securityContext, item by item.** Each requirement was measured by taking it away:
+  - **default seccomp:** daemon starts, every RUN step fails → `Unconfined` is required;
+  - **no `SETUID`/`SETGID`:** rootlesskit dies with
+    `newuidmap … operation not permitted` → both capabilities are required;
+  - **`--read-only` rootfs:** works once the five emptyDirs exist. Its only failure was the
+    probe client's `~/.docker`, which is now an emptyDir;
+  - **minimal caps + Unconfined seccomp:** works, and a RUN step executes.
+- **The full CI path, in the actual CI job image.** Setup: `ghcr.io/catthehacker/ubuntu:act-22.04`
+  running `.gitea/workflows/scripts/images.sh` in verify mode. It downloaded and sha256-checked
+  buildx v0.38.1, connected over mTLS, and bake-built all three `verify` targets from an empty
+  cache. rc 0, 1m32s total:
+  - `TOOLBOX VERIFIED` (42 s);
+  - `AGENT-RUNNER VERIFIED` (26 s): selftest OK, probe "20 refusal(s), 0 failure(s)", and built
+    FROM the in-run toolbox through the `target:` context, with the log showing
+    `[agent-runner-verify toolbox 1/6]` and `base=toolbox-in-this-run`;
+  - `CONFORMANCE-RUNNER VERIFIED` (21 s): all seven refusals;
+  - every stage printed `confirmed: no network`.
+- **mTLS rejects what it should.** Tested with a real BuildKit API call (`buildctl debug workers`):
+  - no client cert → `remote error: tls: certificate required`;
+  - a client cert from another CA → rejected the same way;
+  - the valid cert → accepted.
+
+  Through the driver:
+  - another CA's client cert → rc 1;
+  - the wrong CA for the server → rc 1;
+  - an unreachable host → rc 1 in about 20 s, with the explanatory message;
+  - missing secrets → rc 1, naming the three secrets.
+- **The local podman path**, `build-image.sh` for all three (rc 0).
+  - Negative control: a verify stage expecting a different promtool version printed
+    `DRIFT promtool want 9.9.9` and failed the build.
+  - Negative control: the `--network=none` check fails when the flag is removed.
+- **`buildkit-client-secret.sh`'s sanity checks**, run offline on local certs. They tell apart:
+  - a good client cert;
+  - a server cert (not client-auth);
+  - a mismatched key;
+  - a cert from another CA.
+
+**Measured live, read-only:**
+- node user namespaces, Debian 13.7 and AppArmor (via an Ansible `sysctl`/`cat`);
+- DinD's MASQUERADE rules;
+- the live ClusterPolicies, namespaced Policies, PSA labels, and cert-manager v1.21.3 with its
+  ClusterIssuers;
+- the act-runner pod labels.
+
+**Renovate (unchanged since the first iteration):**
+- the validator with 44.167.0: exit 0;
+- `extract` finds all four markers;
+- the `kubernetes` duplicates are `skipReason: disabled`;
+- 39.264.0 rejects `main`'s config.
+
+**Local gate, CI results:** see the PR body. They are recorded there because this entry is part of
+the tree being gated.
+
+## What I did NOT verify
+
+- **platform/buildkit has never run in the cluster.** It can't until it merges: agents may not
+  `kubectl apply`, and Flux reconciles only `main`. So this PR's own `images` job **cannot build
+  and is expected to fail at the builder preflight**, which is the designed loud failure. The
+  following are therefore all unproven in-cluster:
+  - kubelet admitting the pod;
+  - containerd honouring `appArmorProfile: Unconfined`;
+  - the five emptyDirs;
+  - cert-manager issuing the three certs;
+  - the CiliumNetworkPolicies.
+- **AppArmor `Unconfined` is reasoned, not measured.** My test host runs SELinux, so the AppArmor
+  requirement comes from upstream's example plus the nodes having AppArmor enabled. If the pod
+  were to work under `RuntimeDefault` AppArmor, that line could be tightened; I did not test it.
+- **The local userns mapping is narrower than the cluster's.** Locally it was 65,535 ids across
+  two ranges; in the cluster it is the image's own `100000:65536` against real host subuids. That
+  is the normal case, but it is the cluster's first test.
+- **The NetworkPolicies are untested.** In particular:
+  - that `toEntities: [ingress]` admits the push to the Gateway VIP. The comment explains the
+    reasoning, but it is unmeasured;
+  - that world :443/:80 covers every download the builds make. A dnf mirror on another port
+    would fail a build visibly.
+- **No push, anywhere.** The whole publish path is unexercised:
+  - `REGISTRY_PUSH_TOKEN` reaching buildkitd through the buildx session;
+  - `push=true`;
+  - the metadata digest compared with the registry read-back;
+  - agent-runner FROM `toolbox@sha256:`;
+  - the immutable-tag guard;
+  - idempotence.
+
+  So are the 15 s Envoy route-timeout risk on blob finalisation, and the Gitea PVC (10Gi, shared
+  with repositories) absorbing ~2 GB per toolbox publish until retention runs.
+- **Node disk under real builds.** The cache emptyDir (6Gi limit, 4 GB GC cap) sits on nodes that
+  had 7–9 GB free. It is untested under concurrent pressure.
+- **Certificate rotation is designed, not exercised.** The server cert renews 30 days early but
+  buildkitd only reads it at start; the client copy needs the script re-run.
+- **`--oci-worker-no-process-sandbox` is an accepted risk, not a mitigated one.** A build step can
+  ptrace the daemon and read its TLS key and cache. Anyone with the client cert, which means every
+  PR job, can run build steps.
+- **Renovate has still never completed a run.** It is blocked on #80, on `RENOVATE_TOKEN` gaining
+  `read:package`, and on this branch. The `[email protected]` + 44.x image pairing is
+  untested.
+- **Pods cannot pull these images until PR #61** (the kubelet pull secret) merges.
+- **`registry-retention.sh --apply` has never run**; its keep logic has only run against an empty
+  registry.

+title: "Passkey reconciler review fixes: bind only on git's say-so (rollback sticks), protect the real 26.0.6 sub-flows, screen the requirement PUT by body id, alert on failure"
+---
+
+## What changed
+
+This branch carries the unmerged passkey reconciler (commit `36fcb7b`, cherry-picked with its
+authorship, recorded in `decisions/2026-10-18-keycloak-passkey-reconciler.md`) plus the fixes for a
+review of it. Read that entry for the design; this one records what the review found and what
+changed.
+
+**1. HIGH: the bind was automatic, and rollback did not stick.** Within one tick of merge the
+reconciler would build and BIND `browser-mfa-<hash>`, a login flow no human had tried. Worse, the
+README's rollback (rebind `browser-mfa`) was undone every 15 minutes: the next run found the
+verified candidate again and rebound it, and a hotfix inside the bound flow was "corrected" by
+building and binding an `-r2`.
+
+- New git-declared switch: `bind-browser-flow` in `platform/keycloak/passkey-desired-state.yaml`,
+  a second key of the same ConfigMap, so it reaches the pod through the existing mount. **Default
+  `"false"`.** It is the one hand-edited line in a generated file: the renderer carries it through
+  on `--write`, and `--check` (run by the L0 gate) refuses anything but the quoted strings `"true"`
+  / `"false"`. An unquoted `true` is a YAML boolean, which a ConfigMap rejects at apply time and
+  which would have failed the whole `platform-config` Kustomization, realm import included.
+- `"false"`: pass 3 builds and verifies the candidate (or reuses a verified one), logs
+  `WOULD BIND <alias>`, exits 0 with `KEYCLOAK_PASSKEY_RECONCILED_OK_PENDING_BIND`, and never PUTs
+  a changed `browserFlow`. That holds after an earlier bind too, so the operator's rebind sticks.
+  If the bound flow *is* the candidate alias and has been hand-edited, it is left alone (no `-r2`
+  is built beside it).
+- `"true"`: binds as before, and keeps asserting it. That is GitOps working; the README says so,
+  and says not to hotfix the flow while it is `"true"`.
+- The CronJob passes no flag. `--no-bind` still exists for a hand-run Job and can only narrow
+  git's value. The L0 check asserts the CronJob carries no `--` argument.
+- Rollback is now: a PR setting `"false"` (first), then one rebind write. README documents the
+  order and why it matters, plus how to test the candidate on one client (a per-client
+  `account-console` browser-flow override) before the go-live PR.
+
+**2. HIGH: the protected-subtree guard read the wrong field for sub-flows.** Read from source at tag
+26.0.6 (`services/src/main/java/org/keycloak/services/resources/admin/AuthenticationManagementResource.java`,
+fetched from GitHub this session): `recurseExecutions` sets `displayName = flowRef.getAlias()` and
+`flowId` on a sub-flow row and never calls `setAlias`. `alias` is set only on authenticator rows,
+where it holds the bound **config's** alias. So the protected set was `{bound}` alone, and a write
+into `browser-mfa-forms` would not have been refused. The old stub returned `alias` on sub-flow
+rows, which is why all 216 assertions passed anyway.
+
+- New `subflow_alias()` reads `displayName` and cites the source. I did not resolve by `flowId`:
+  `getFlows()` (same file) filters to `isTopLevel()`, so a nested sub-flow's id resolves to nothing
+  through the flows list. A sub-flow row with no `displayName` makes the listing unreadable, which
+  leaves the flow pass fail-closed.
+- The stub now returns rows shaped like 26.0.6's: sub-flow rows carry `displayName`, `flowId` and no
+  `alias`/`providerId`. Authenticator rows carry a display *type* as `displayName` (not the
+  provider id) and the config alias as `alias`. Nulls are omitted.
+- New assertions: after a real run, `browser-mfa-forms` and `browser-mfa-conditional-otp` are in
+  the protected set, and an execution add or requirement write into them is refused. A missing
+  `displayName` fails closed.
+
+**3. MEDIUM: `PUT /flows/{alias}/executions` was screened on the wrong field.** `updateExecutions`
+resolves `realm.getAuthenticationExecutionById(rep.getId())` without checking membership in
+`{alias}`. The same handler also renames the flow named by `rep.getFlowId()` when the body carries
+`authenticationFlow` + `displayName`. Now:
+
+- `body["id"]` is screened against the protected execution ids.
+- It must also be in `_BUILD_EXECUTION_IDS`: the ids read back from the flow this call just
+  created, open only inside `build_flow`.
+- The config `POST /executions/{id}/config` is held to the same build scope.
+- The body may carry only `id`, `requirement` and `priority`.
+- Selftest cases cover each of these.
+
+**4. Stale docs on sensitive paths** now describe what ships, including the switch:
+`platform-config/kustomization.yaml`, the chainsaw test header, the desired-state header and its
+renderer template, the renderer's own header and `--check` message, and the README.
+
+**5.**
+- `backoffLimit: 0`: every failure is deterministic within a tick, and a retried build burns
+  another of the 5 candidate aliases.
+- New alert `KeycloakPasskeyReconcilerFailing` in `platform/monitoring/alerts.yaml` (warning,
+  `for: 15m`, `kube_job_status_failed` on `job_name=~"keycloak-passkey-reconciler-.*"`), the same
+  shape as the sibling's. It has promtool tests in
+  `platform/monitoring/tests/keycloak-passkey-reconciler.test.yaml`, in both directions plus
+  "the sibling's failure is not this alert" and "one transient failure stays quiet". The alert
+  ratchet in `alert-rules-unit-tested` would have refused it untested. A new runbook,
+  `runbooks/keycloak-passkey-reconciler.md`, is projected by the runbooks generator.
+- The stale "Renovate does not manage plain `image:` tags" comment is corrected: `renovate.json5`
+  enables the `kubernetes` manager over `platform/**`. The image is pinned to
+  `python:3.13.15-alpine3.23@sha256:6438599575cca0d1df94aeee0d2ae088d4d8846eab554b2ee7784a3a6df0d516`,
+  the multi-arch index digest read from Docker Hub today. The tag is mutable: the sibling
+  reconciler's pod on prod reports `imageID ...@sha256:75f27d68...` under the same tag, which is
+  neither today's index nor today's amd64 manifest.
+
+**6. Hygiene.** The ~160-line header that appeared in both the YAML and the script is now kept once,
+in the script, where it ships next to the code and its selftest. A short header above the
+ConfigMap points to it. Nothing else was restructured, apart from the build's second half moving
+into `_finish_build()` so the build scope can be opened and closed around it.
+
+Sensitive paths touched: `ci/**` (renderer), `conformance/**` (L0 check, mutations, chainsaw),
+`platform-config/kustomization.yaml` (comment only). This needs the operator's
+`/approve-override` or a non-author review. I did not post one.
+
+## What I verified
+
+- **Local toolbox gate, rc 3** (pinned toolbox via `dev.sh`, `DEV_KUBECONFIG=/dev/null`, ENGINE
+  shim bind-mounting the main `.git`, run on the committed branch). Stages: `spec-immutability`
+  pass (the spec repo resolved as a sibling), `decisions-log` pass, `lint` pass, `l0` pass
+  (including `keycloak-passkey-reconciler`, `alert-rules-unit-tested` and
+  `alert-runbooks-resolvable`), `render-golden` pass, `l1` pass, `approval-policy` pass (N/A
+  offline; it is guaranteed to fail in CI). **`gitea-settings` did not run** (no
+  `SETTINGS_API_TOKEN` locally) and is the only stage that did not run. L2/L3 `conformance` is
+  skipped by design (no cluster). rc 3 is **not** green.
+- `platform/monitoring/tests/run.sh platform/monitoring/tests/keycloak-passkey-reconciler.test.yaml`
+  in the toolbox: `promtool check rules` SUCCESS (54 rules), `promtool test rules` SUCCESS,
+  promtool 3.14.0.
+
+- **Selftest: 259 assertions pass** (was 216), extracted from the shipped ConfigMap by the L0
+  check.
+- **`mutations.py`: 40 of 40 injected regressions caught** (was 30). The ten new ones each undo
+  one fix:
+  - sub-flows read by `alias` again;
+  - an unnameable sub-flow tolerated;
+  - the requirement PUT screened on its path only;
+  - execution writes not held to the build tree;
+  - extra body keys allowed;
+  - the bind switch ignored in `run()`;
+  - the bind switch ignored in `reconcile_flow()`;
+  - an absent switch reading as true;
+  - an invalid switch guessed at;
+  - `-r2` built beside a hand-edited bound flow.
+  "Sub-flows by `alias`" is caught less cleanly (the selftest aborts on an unreadable listing
+  rather than failing an assertion). It is still caught.
+- The renderer accepts `"true"` and `"false"` and refuses `true` (unquoted) and `"yes"`. I
+  checked this by hand-editing the committed file and running `--check`.
+- The 26.0.6 source for `recurseExecutions`, `updateExecutions` and `getFlows` was read directly
+  (lines ~225-231, 658-724 and 747-806 of the file at that tag).
+- Read-only `kubectl --context k3s-prod`: Keycloak pods run `quay.io/keycloak/keycloak:26.0.6`
+  (2 replicas). The only CronJob in `keycloak` is `keycloak-client-secret-reconciler`, so the
+  passkey reconciler is **not** live.
+
+## What I did NOT verify
+
+- **Nothing has run against a real Keycloak.** The stub's row shapes now follow the 26.0.6
+  source, but they are still my reading of that source, not a captured response. In particular,
+  I have never seen a live executions listing to confirm `displayName` on a sub-flow row. If it
+  differs, the failure is fail-closed (no build), not fail-open.
+- **The candidate flow has never been tested in a browser.** That is now a precondition of the
+  go-live PR (README, "Testing the candidate flow before binding it"). Nobody has run those steps.
+  I also have not checked that the per-client `account-console` override behaves as described on
+  26.0.6.
+- **"Merging changes nothing users see" is true of login, but passes 1 and 2 still write the
+  realm.** They set the passwordless policy and enable the enrolment action. That action is
+  enabled by default in 26.0.6, but I did not read the live realm, because no admin API calls were
+  allowed. Pass 3 also creates the unbound candidate flow (realm DB writes, invisible to login).
+- **Race in pass 1, not fixed:** the policy PUT is a read-modify-write that carries `browserFlow`
+  back from its own GET. An operator rebind landing between that GET and PUT would be reverted.
+  The window is one HTTP round trip and only exists when the policy has drifted.
+- **The alert has never seen a real series.** The CronJob has never run, so
+  `kube_job_status_failed{job_name=~"keycloak-passkey-reconciler-.*"}` does not exist yet. Its
+  shape is copied from the sibling's rule, which does have live series.
+- **The digest is of today's index.** I did not pull it or run the image. Renovate's handling of a
+  `tag@digest` pin under the `kubernetes` manager is from its documentation, not from a Renovate
+  run here.
+- **CI's own result** is in the PR, not here. `approval-policy` is expected to fail until the
+  operator overrides.
+
+### Follow-ups (out of scope here, deliberately not done)
+
+- A dedicated least-privilege service-account client for the reconciler, instead of the
+  master-realm break-glass admin it shares with the client-secret reconciler.
+- A NetworkPolicy for the `keycloak` namespace.
+- Whether a passkey login should skip TOTP for platform-admins. This is the PR #72 design
+  decision, currently "no TOTP after a passkey".
+- A `KeycloakPasskeyReconcilerStale` rule (no successful run in N hours), like the sibling's.
+  Only the failure alert was in scope.

+title: Renovate has failed every run since #79 — the workflow still named renovate.json
+---
+
+## What changed
+
+**`.gitea/workflows/renovate.yaml`** — `configurationFile: renovate.json` → `renovate.json5`.
+
+PR #79 (`fix/renovate-invalid-config`) renamed the config to `renovate.json5` and did not update
+the one line in the workflow that names it. Measured 2026-10-29 from the Gitea Actions log of run
+322 (task 513, schedule, 08:15 UTC):
+
+    Error: ENOENT: no such file or directory, stat '/workspace/Home-Network/home-network-k3s-impl/renovate.json'
+
+Runs 315–322 (2026-10-22 → 10-29, every one listed) are all `failure` on the `schedule` event,
+each failing in about one second. Renovate never started. `RENOVATE_TOKEN` **does** exist as a
+repository Actions secret (listed by name via the API; value not read), so the token preflight
+passes and this filename is the only blocker observed.
+
+**`ci/lint.sh`** — a new assertion after yamllint: every non-comment `configurationFile:` key in
+`.gitea/workflows/*.y*ml` must name a path that exists. This is valid YAML, so yamllint cannot see
+it, and the gate stayed green through 11 days of failures.
+
+**Second blocker, same PR:** the workflow did not pin a Renovate version, so
+`renovatebot/[email protected]` ran its default, Renovate **39** (`action.yml`:
+`renovate-version` `default: '39'`, read at that tag). `renovate.json5` uses `managerFilePatterns`,
+which needs >= 40.2.0. Under 39.264.0 the validator rejects the config with five errors. This was
+found and reproduced by the image-pipeline worker (PR #81). #79 had validated against `latest`. Pinned
+`renovate-version: 44.167.0`, the version the config validates clean against per that worker.
+
+## What I verified
+
+- The root cause, from the run log quoted above, and that `origin/main` has `renovate.json5` and
+  no `renovate.json` (`git ls-tree`).
+- The new guard, both ways, run standalone: on this branch it prints
+  `workflow configurationFile references resolve`, rc 0. With the line reverted to `renovate.json`
+  it prints `configurationFile 'renovate.json' does not exist in the repo`, rc 1. My first version
+  also matched its own explanatory comment in the workflow and failed. That is why the grep is
+  anchored to non-comment lines.
+- Toolbox gate: result and rc are reported in the PR, not predicted here.
+
+## What I did NOT verify
+
+- **The 39.x rejection and the 44.167.0 pass were not reproduced by me.** I confirmed only the
+  action's default (`'39'`). The validation results are the PR #81 worker's.
+- **Renovate has still never completed a run.** This removes the observed blocker. Others may
+  follow it. The test is a `workflow_dispatch` with `dry_run: true` after merge, and its log is
+  the first evidence that Renovate authenticates, extracts dependencies, and honours `.json5`.
+- **The `enabledManagers: ["regex"]` vs `custom.regex` question** (#73, #77) is still open. The
+  same dry-run log answers it: look for the regex/custom manager's dependency-extraction count.
+- **No alert for "Renovate keeps failing".** The guard prevents this specific cause from recurring.
+  Nothing notices a scheduled workflow that is red every day. That gap stays open.
+- **Sensitive path.** `.gitea/**` and `ci/**` are both in `approval-policy.json`. CI will block
+  on `approval-policy` until the operator posts `/approve-override` as a review. The local gate
+  reports that stage as N/A.

+title: The registry push 403 is Cilium refusing buildkitd's EGRESS at the Gateway — fixed in platform/buildkit, not in Gitea's ingress
+---
+
+## What changed
+
+**`platform/buildkit/networkpolicy.yaml`** — `buildkitd-allow-egress` gains one rule:
+`toEndpoints {io.kubernetes.pod.namespace: gitea, app.kubernetes.io/name: gitea}` on TCP 3000,
+with a comment carrying the measurement. `platform/buildkit/README.md`'s policy row says the same.
+
+**What did NOT change, deliberately:** `catalog/gitea.yaml` `inClusterClients` and
+`apps/wave-0/gitea.yaml`. The brief proposed admitting `buildkit` there. The evidence below says
+that is the wrong policy: Gitea's ingress is not what refuses the push, and adding it would only
+open the direct ClusterIP path from build code to Gitea, which nothing uses.
+
+### Why: the brief's hypothesis was half right
+
+Images run 337 failed its push with `HEAD .../blobs/sha256:5855... 403 Forbidden: Access denied`.
+The PM's hypothesis was that this was Cilium's Envoy denying the request, not Gitea. **That part
+holds.** The hypothesis also said the denial came from Gitea's *ingress* policy, which does not
+admit the `buildkit` namespace. **That part is wrong.** The denial is enforced on buildkitd's own
+*egress*. Since Cilium 1.16.8/1.17.2 (CVE-2025-30162; prod runs `cilium:v1.20.1`), the Gateway's
+L7 load balancer re-evaluates the source pod's egress policy against the identity of the backend
+it resolves to. buildkitd's egress allowed `world` :443/:80 and the `ingress` entity. That gets
+the TCP connection to Envoy, but no rule matches Gitea's backend identity, so Envoy answers
+`403 Access denied` without forwarding the request. This is the failure commit `68690e5` fixed for
+every SSO app's hop to Keycloak, and the fix has the same shape. Keycloak's ingress names no app
+namespaces either.
+
+## What I verified
+
+All measurements are read-only, against `k3s-prod`, on 2026-10-30 around 05:27–05:37 UTC.
+
+- **Gitea never saw the failed push.** Its router log for the previous 12h had 316 `/v2/` lines
+  and **0** that were `toolbox/blobs`, PUT, POST or PATCH. It also had **0** from buildkitd's pod
+  IP (`10.0.0.7`). In the same window it logged the CI job's own `HEAD .../toolbox/manifests/
+  sha-0dd57fbaf002 → 404` from the act-runner pod (`10.0.0.38`). Requests that came through the
+  Gateway reach Gitea and get logged. This one never arrived.
+- **A reproduction with no credentials.** An unauthenticated `GET https://gitea.home.keithjackson.dev/v2/`
+  (Gateway VIP `192.168.2.20`) gave:
+  - from the buildkitd pod: **`403 Forbidden`**, with no matching line in Gitea's log;
+  - from the act-runner pod's `dind` container: **`401 Unauthorized`**, which is Gitea's normal
+    registry challenge, logged by Gitea as `GET /v2/ for 10.0.0.38:0, 401`.
+
+  No token was involved, so this cannot be a package-permission problem. The bot account and the
+  `REGISTRY_PUSH_TOKEN` were not the cause, and the operator does not need to change them.
+- **Hubble names the enforcement point.** On `cilium-55jv8`, buildkitd's node:
+  `buildkit/buildkitd-859d67c8f8-x44nh (ingress) -> gateway/cilium-gateway-shared:443 http-request
+  DROPPED (HTTP/1.1 GET https://gitea.home.keithjackson.dev/v2/)`, followed by `http-response
+  FORWARDED (HTTP/1.1 403 0ms)`. In the JSON form, **`traffic_direction: EGRESS`**. Envoy wrote
+  the 403 itself in 0 ms.
+- **Gitea's ingress does not need the source namespace.** The act-runner pod's namespace
+  (`gitea-actions`) is **not** in Gitea's ingress allows. Its NetworkPolicy
+  `default-deny-ingress-allow-egress` has an `{}` egress rule, so its egress is unrestricted. Its
+  requests through the Gateway still reach Gitea. `cilium-dbg bpf policy get` on Gitea's endpoint
+  (1876 on `cilium-9rk5x`) shows all Gateway traffic admitted as `reserved:ingress 3000/TCP`
+  (391 MB, 1.19 M packets) and no row for `gitea-actions`. The source-identity check therefore
+  happens on the source's egress, not on the destination's ingress.
+- **The policy gap is visible in the BPF map.** `bpf policy get 83` (buildkitd) has these egress
+  rows and nothing else: `reserved:world` 80/443, `reserved:ingress ANY`, and kube-dns 53. There
+  is no Gitea identity.
+- The edited YAML parses (three documents, names unchanged).
+
+## What I did NOT verify
+
+- **That this rule turns the 403 into a 401/200. UNVERIFIED.** That needs the policy applied, which
+  is a Flux/operator action. My confidence is high but not proven, and it rests on two things. The
+  Hubble verdict is EGRESS. Commit `68690e5` made the identical change for Keycloak and recorded
+  "Verified live: headlamp-ns -> keycloak discovery 403 -> 200".
+- **The port restriction.** The rule names `3000`, Gitea's container port, which is the upstream
+  port Envoy connects to. The Keycloak precedent has no port. If the 403 survives, the first thing
+  to test is whether L7LB enforcement uses the frontend :443 instead. I expect it does not.
+- **Run 337's own flows.** The Hubble ring buffer had already rotated past them, and buildkitd had
+  been restarted since (the pod was 18 minutes old). The reproduction above uses the same path, the
+  same pod spec and the same policy, but it is not the original request.
+- Envoy's access logs in the `cilium-envoy` pods. Hubble's L7 flow already shows the drop, so I
+  did not read them.
+- The push itself, the Renovate digest flow, and whether the bot team's `Packages=Write` is enough
+  for a first push that creates a new package. These only become testable after this lands.

+---
+
+## What changed
+
+- **`catalog/{pihole,jackett,plex}.yaml` `source.image`** pinned to the tag whose digest was
+  already running, so the *image* does not change:
+  - `pihole/pihole` (no tag) -> `pihole/pihole:2026.10.0`
+  - `lscr.io/linuxserver/jackett:latest` -> `lscr.io/linuxserver/jackett:v0.24.2865-ls7`
+  - `plexinc/pms-docker:latest` -> `plexinc/pms-docker:1.43.4.10903-e5521bd8c`
+- **`apps/wave-0/{pihole,jackett,plex}.yaml`** re-rendered (`render.py --all catalog -o apps
+  --wave-layout --no-image-automation`, in the toolbox). The diff is exactly the three app-container
+  `image:` lines; nothing else moved.
+- **`catalog/jackett.yaml`** `update.range` comment: "stay on the Jackett 0.22.x stable line" was
+  false (0.24 runs, and `>=0.22.0` has no ceiling). Range unchanged; comment corrected.
+- **`renovate.json5`**, four packageRules plus a comment block:
+  - jackett `versioning: regex:^v(major).(minor).(patch)-ls(build)$` (Renovate's linuxserver example).
+  - jackett **`overridePackageName: ghcr.io/linuxserver/jackett`**: not in the brief, and needed.
+    Renovate's docker datasource reads at most `dockerMaxPages` (20, a global-only option) tag
+    pages from any host except a short list that includes ghcr.io (1000 pages). lscr.io is not on
+    that list. Jackett has **32,093** tags, oldest first, ~1000 per page; the running tag is #31,980.
+    Before this rule the dry run extracted jackett at `v0.24.2865-ls7` and **proposed nothing**,
+    with no warning. The override changes only the lookup; the manifests keep `lscr.io/...`.
+    Every jackett rule matches on `depName`, because the override rewrites `packageName`.
+  - jackett `schedule: after 3am and before 6am on sunday`, i.e. weekly. Measured: 13 ls builds in
+    12 days (ls7 built 2026-10-17, ls20 built 2026-10-29). Each is a `patch` and auto-merges, so on
+    the daily window it would mean a PR, a gate run and a jackett restart (Recreate) every day.
+    Weekly picks the newest tag, so it skips nothing. `catalog/jackett.yaml update.cadence` still
+    says daily. That field fed the retired Flux image-automation, and the rule's description
+    says the rule is now the cadence that takes effect.
+  - plex `versioning: regex:^(major).(minor).(patch).(build)-[0-9a-f]+$`.
+  - pihole: **no rule**, as the operator decided. CalVer parses under default docker versioning.
+    Patches and minors auto-merge, and a year rollover is a major (dashboard approval). This is
+    written in a comment.
+  - Corrected the "WHAT RENOVATE STILL CANNOT FIX" comment. It listed these three as floating;
+    they publish immutable version tags.
+  - No `allowedVersions` mirror was added. None of the three catalog ranges has a ceiling
+    (`>=2024.0.0`, `>=0.22.0`, `>=1.40.0`), so #86's mirror has nothing to encode for them.
+- **Runbooks:** `image-policy-stalled.md` no longer says jackett and pms-docker are
+  `latest`-only. In `plex-quicksync.md`, "the floating-image caveat" became "the image-version
+  caveat", because the deployment no longer runs `:latest` with an implicit `Always`, and the symptom
+  is now "after a pms-docker bump". `plex-claim.md`'s two "running `:latest`" mentions are
+  now in the past tense.
+
+## What I verified
+
+- **Live digests** (read-only `kubectl --context k3s-prod`, pod `.status.containerStatuses[].imageID`):
+  pihole-0 and pihole-1 `sha256:d34134716fc3…`, jackett `sha256:4fcf3cc22dd3…`, plex
+  `sha256:e0ab27395614…`.
+- **Each chosen tag resolves to the same digest** (anonymous registry HEAD, OCI index + manifest-list
+  Accept): `pihole/pihole:2026.10.0` = `sha256:d34134716fc3…`; `ghcr.io/linuxserver/jackett:v0.24.2865-ls7`
+  = `sha256:4fcf3cc22dd3…`; `plexinc/pms-docker:1.43.4.10903-e5521bd8c` = `sha256:e0ab27395614…`.
+  (For contrast, `pms-docker:latest` is now `sha256:6d778d41…` and `jackett:latest` `sha256:ee6ae915…`.
+  The pods would have drifted on their next restart.)
+- `renovate-config-validator` (ghcr.io/renovatebot/renovate:44.167.0) reports "Config validated
+  successfully". The only warning is the existing `docker` block migration.
+- **Renovate dry run** (`RENOVATE_PLATFORM=local`, `--dry-run=full`, 44.167.0, anonymous, includePaths
+  limited to the six files). It extracted all three from both `catalog/` (custom regex) and
+  `apps/wave-0/` (kubernetes) under the same depName, so each lands in one branch:
+  - plex `1.43.4.10903-e5521bd8c` -> `1.43.5.11079-b3b13e506` (patch, `renovate/plexinc-pms-docker-1.x`)
+  - jackett `v0.24.2865-ls7` -> `v0.24.2961-ls20` (patch, `renovate/lscr.io-linuxserver-jackett-0.x`).
+    This needs the ghcr override; without it there was no proposal.
+  - pihole `2026.10.0` -> none. That is correct, because 2026.10.0 is the newest numbered tag on Docker Hub.
+- **Automerge, schedule and dashboard flags** come from Renovate's own `applyPackageRules`
+  (datasource-merge, then update-type-merge, the same order as `flatten.js`), run on the resolved
+  config. The local platform does not run the branch worker:
+  - plex patch: automerge **true**, daily window.
+  - jackett patch: automerge **true**, schedule **sunday** window.
+  - pihole (synthetic updates) `2026.10.1` patch and `2026.11.0` minor: automerge **true**. `2027.01.0`
+    major: automerge **false**, `dependencyDashboardApproval` **true**, +needs-review/breaking.
+- **Versioning filters** (Renovate's versioning module): the jackett regex rejects `latest`, bare
+  `0.24.2961`, `amd64-…` and `development-…`. The plex regex rejects `latest`, `public`, `beta`,
+  `plexpass` and `…-amd64`/`…-arm64`. Docker versioning ranks `2026.09.0 < 2026.10.0`.

+
+## What I did NOT verify
+
+- **That the merge is restart-free. It is not.** The pod-template `image` string changes, so Flux
+  rolls all three: plex and jackett are `Recreate`, so each has a brief outage, and pihole is a
+  2-replica StatefulSet that rolls one pod at a time. The digest is identical, so the image's
+  behaviour should not change, but the kubelet resolves the new tag name and may pull it. The
+  rollout itself was not observed.
+- The implicit `imagePullPolicy` moves from `Always` (`:latest` or no tag) to `IfNotPresent`. This is
+  intended, and was not observed live.
+- A real (non-dry) Renovate run against Gitea, and whether the Sunday window actually opens a jackett
+  PR. The schedule was only evaluated, not exercised.
+- Other `lscr.io/linuxserver/*` images (radarr, sonarr, qbittorrent) may hit the same 20-page
+  truncation once their tag counts grow. Not measured here, and not changed.
+- Plex not self-updating on a version tag was checked only against the running pod (read-only
+  `kubectl exec cat`). `/etc/cont-init.d/50-plex-update` does `exit 0` when `version` from
+  `/version.txt` equals the installed `plexmediaserver` package. Both are
+  `1.43.4.10903-e5521bd8c`. I did not boot a pod on a *new* tag to watch that short-circuit.

+title: PM agent — #61 rebased onto the CI image pipeline, first published digest pinned, and the remaining path to live audited
+---
+
+## What changed
+
+PR #61 (`feat/pm-agent-registry-pull-secret`, the kubelet pull credential and admission rule
+7) was rebased onto `origin/main` after #81 (CI image pipeline), #82 and #83. Conflicts in
+`docs/plans/pm-agent-issue-to-pr.md`, `platform/pm-agent/README.md` and
+`runbooks/pm-agent.md` were resolved keeping both sides: #61's "pull credential now wired"
+and #81's "CI publishes, Renovate bumps". No manual build-and-push text came back.
+
+On top of the rebase, as a second commit:
+
+- **The first published digest is pinned**: `deployment.yaml` and `PM_WORKER_IMAGE` in
+  `configmap.yaml` now name
+  `gitea.home.keithjackson.dev/home-network/agent-runner@sha256:c4eba5b3c508bf456a03391ac76f8275e7ea28a829da1450d99f6f6f25c6eb42`
+  (images run 340, tag `sha-523cd9118f95`, which is also `main`). The `# renovate-digest:`
+  markers are unchanged and still sit on the line directly above each value, so later bumps
+  stay Renovate's. Pinning by hand once removes the dependency on Renovate's first-ever run.
+- **The first run is dry, and scoped to a label**: `PM_DRY_RUN: "true"`,
+  `PM_REQUIRE_LABEL: "agent"` (the plan's follow-up 3); `config-generation` bumped to `2`.
+  Dry run is also a *correctness* requirement, not only caution: the pinned digest was
+  built before this PR added `imagePullSecrets` to the worker Job template, which is baked
+  into the image. Admission now requires that entry, so a worker Job built from the run-340
+  image would be denied. Merging this PR touches `infra/agent/**`, so `images.yaml`
+  re-publishes agent-runner; Renovate's bump to that digest is what makes workers
+  admissible. Only then flip `PM_DRY_RUN` to `false`.
+- **The token scope list was wrong; it is fixed.** Gitea 1.24.3's `routers/api/v1/api.go`
+  closes the `/user` route group with `tokenRequiresScopes(AccessTokenScopeCategoryUser)`,
+  and the dispatcher's first call is `GET /user`. The documented scopes are now
+  `read:user`, `write:repository`, `write:issue`, `read:package` everywhere (both
+  `.example`s, README, runbook row).
+- **Org-package permission is documented separately from the scope.** Per
+  `services/context/package.go` `determineAccessMode` (v1.24.3), a non-admin's access to an
+  org-owned package is the highest Packages-unit mode across its org teams, else read if the
+  org is visible to it. Home-Network is `public`, so it works today by visibility alone; the
+  registry `.example` now has the operator create a `pm-agent-pull` team (no repositories,
+  Packages = Read) so it does not depend on that.
+- **`sops` is toolbox-only**: both `.example`s now say so and give the in-place
+  `./infra/devcontainer/dev.sh run sops <file>` edit (the same procedure
+  `runbooks/vpn-remote-access.md` documents), which writes no plaintext file.
+- The runbook's Secret-key check used `-o jsonpath='{.data}'`, which prints values before the
+  pipe trims them; it is now a `go-template` that emits key names only. Two new runbook
+  rows: the `read:user` 403, and the admission denial from a pre-#61 digest.
+
+## What I verified
+
+- **Registry digest**, read-only from the registry API (bearer token from `/v2/token`,
+  `HEAD /v2/home-network/agent-runner/manifests/<tag>` with OCI and Docker accept headers):
+  `main` and `sha-523cd9118f95` both answer `200`,
+  `Docker-Content-Digest: sha256:c4eba5b3…6eb42`, `application/vnd.oci.image.manifest.v1+json`.
+  Tags list: `[main, sha-523cd9118f95]`. The admission pattern
+  `gitea.home.keithjackson.dev/home-network/agent-runner@sha256:*` matches the pinned value.
+- **#81's claim that the template's digest needs no tracking holds**: `pm-dispatch.build_job`
+  sets `containers[0].image = cfg.worker_image` (from `PM_WORKER_IMAGE`) on every Job.
+  Renovate's `renovate-digest` custom manager only matches `platform/pm-agent/*.yaml` and
+  `versions.env`, so the template is not touched by it.
+- **Node path to the registry, read-only over SSH, all three prod nodes**: `/etc/hosts` line 9
+  is `192.168.2.20 keycloak.home.keithjackson.dev gitea.home.keithjackson.dev`, nsswitch is
+  `hosts: files dns`, and `curl https://gitea.home.keithjackson.dev/v2/` from the node answers
+  `401` with `ssl_verify_result=0` and `remote_ip=192.168.2.20`. That is the host resolver,
+  which is what containerd (a node process) uses; a pod's view would not have shown it.
+- **Network path from the namespace**: dispatcher and worker both use
+  `PM_GITEA_URL=http://gitea.gitea.svc.cluster.local:3000` (ConfigMap, Job template, and
+  `pm-worker`'s hard allowlist, which refuses anything else); the git remote and the API base
+  are both derived from it. So nothing goes through the Gateway and #83's
+  `toEndpoints`-through-Gateway issue does not apply. Egress: `toEndpoints` gitea pods `:3000`
+  (both CNPs), `kube-apiserver` (dispatcher only), `world:443` (the model). Ingress on the
+  Gitea side: `gitea-allow-pm-agent-ingress` exists live and is `VALID True`.
+- **Live state (read-only, `--context k3s-prod`)**: namespace `pm-agent` exists; Deployment
+  `0/1`, pod `ImagePullBackOff` for 24d on the all-zero digest; Secret `pm-agent-credentials`
+  (2 keys) exists, `pm-agent-registry` does not yet (it ships in this PR); Flux Kustomization
+  `pm-agent` Ready at `main@dfc432c`; ClusterPolicy `pm-agent-job-shape` Ready.
+- **Gitea state (read-only API)**: 1.24.3; org Home-Network `public`; no user `pm-agent`
+  exists; teams are `Owners` and `registry-push`; collaborators are `jakman85` (owner) and
+  `renovate-bot` (write); the repository has **no labels** and **no open issues**.
+- **Placeholders, without decrypting**: the registry ciphertext decodes to 155 bytes, exactly
+  the length of the `.example`'s placeholder JSON. The credentials values decode to 57 and 39
+  bytes — neither a 40-char Gitea token nor a ~100-char Claude OAuth token. Both files'
+  `lastmodified` is the commit that created them as placeholders.
+- `kyverno test`, `PM_SELFTEST=1 pm-dispatch` and the gate: numbers in the PR description and
+  the final handoff report for this run.
+
+## What I did NOT verify
+
+- **Any authenticated pull, poll or worker.** No `pm-agent` account or token exists, so the
+  scope set has not been exercised end to end. The `read:user` requirement is read from
+  Gitea's v1.24.3 source, not from a live 403.
+- **That the credentials ciphertext is a placeholder.** Lengths are strong evidence, not
+  proof; I did not decrypt.
+- **That Renovate will open the post-merge bump.** Its token was being re-minted at the time
+  of writing and it has never completed a run here. Renovate's `kubernetes` manager also
+  scans `infra/agent/*.yaml` and `platform/**`; what it does with a digest-only reference
+  with no tag (the template) is unmeasured.
+- **The dispatcher's `claude --print` call to `api.anthropic.com`** through `world:443`, and
+  whether the run-340 image's dispatcher behaves as this tree's code does (it predates #61's
+  selftest line, nothing else in `pm-dispatch.py`).
+- **The admission policy against a real Job.** Still never admitted or refused one live.

+title: Renovate's token needs five scopes, not three; the workflow documented the wrong list, and now probes it
+---
+
+## What changed
+
+**The fix is operator-side.** `RENOVATE_TOKEN` lacks `read:organization`, and it will next lack
+`write:issue`. The operator must re-mint it with five scopes:
+
+- `read:user`
+- `read:organization`
+- `write:repository`
+- `write:issue`
+- `read:package`
+
+The git half fixes the two things that sent the operator round this loop twice.
+
+**`.gitea/workflows/renovate.yaml`**:
+- **The header's scope list is corrected**, with the call each scope serves. The old list named
+  only `write:repository`, `read:user` and `read:package`, and the operator minted exactly that.
+  The preflight's "TO FIX" text is corrected the same way.
+- **A new step, "Preflight - the token has every scope Renovate needs".**
+  - It probes read-only GETs: `/user` for read:user, `/orgs/Home-Network` for read:organization,
+    `/repos/{repo}` for read:repository, `/repos/{repo}/labels` for read:issue, and registry
+    `/v2/token` for read:package.
+  - It reads the token's own scope list out of Gitea's 403 from `/admin/orgs` (names only), and
+    requires `write:repository` and `write:issue` in it.
+  - It says what a failure means: 401 is the value; a Gitea 403 is a scope, and the probe prints
+    Gitea's message; an "Access denied" 403 is a Cilium/Envoy denial.
+  - The token is fed to curl on stdin (`--config -`), never in argv.
+
+**`ci/lint.sh`**: a new guard rejects any non-comment `uses:` in `.gitea/workflows` that needs a
+Docker daemon: `docker://`, `renovatebot/github-action` and Docker's daemon-bound
+`docker/*-action`s. That is the class of bug fixed in #84.
+
+### Root cause, with evidence
+
+Run 350 (task 567, 06:49 UTC) **got further than 348 and 349.** Gitea's router log, filtered to
+the act-runner pod `10.0.0.38`:
+
+    06:49:31 GET /api/v1/user                                   200 OK
+    06:49:31 GET /api/v1/version                                200 OK
+    06:49:31 GET /api/v1/repos/Home-Network/home-network-k3s-impl  200 OK
+    06:49:31 GET /api/v1/orgs/Home-Network                      403 Forbidden
+
+There were no `/v2/` requests: Renovate stopped before extraction. From the job log, verbatim:
+
+    ERROR: Repository has unknown error (repository=Home-Network/home-network-k3s-impl)
+      "url": "https://gitea.home.keithjackson.dev/api/v1/orgs/Home-Network",
+      "message": "token does not have at least one of required scope(s), required=[read:organization], token scope=read:package,write:repository,read:user"
+      "x-envoy-upstream-service-time": "27", "server": "envoy"
+    INFO: Repository finished ... "result": "unknown-error", "exitCode": 8
+
+**This is not Cilium.** The body is Gitea's JSON scope message, Gitea logged the request, and
+`x-envoy-upstream-service-time` shows that Envoy forwarded it upstream.
+
+**The secret WAS updated.** Runs 348 and 349 got `GET /user 403` from `tokenRequiresScopes`. Run 350
+got `/user 200`, and its token scope list now includes `read:user`.
+
+**Why `read:organization` is needed.** Renovate 44.167.0, `lib/modules/platform/gitea/index.ts`
+`initRepo`, calls `helper.isOrg` → `GET /orgs/{owner}` and rethrows on error. Gitea 1.24.3,
+`routers/api/v1/api.go`, puts `/orgs/{org}` behind
+`tokenRequiresScopes(AccessTokenScopeCategoryOrganization)`.
+
+**Why `write:issue` is needed next.** In the same `api.go`, `/repos/{o}/{r}/issues…`, `/labels`
+and `/milestones` sit in a group with `tokenRequiresScopes(AccessTokenScopeCategoryIssue)`
+(lines 1466–1582). Renovate's gitea-helper uses `/issues`, `/issues/{n}/labels`, `/labels` and
+`/issues/{n}/comments`, for the dependency dashboard (`:dependencyDashboard` is extended) and for
+PR labels. A dry run only reads them; a scheduled run writes them.
+
+The other causes the coordinator listed are ruled out:
+- **Schedule window and dry-run.** The run never reached branch processing.
+- **Repository config.** The run never reached the clone (`"cloned": undefined`).
+- **The Summary step.** It is not involved; the failure is Renovate's own exit 8.
+
+## What I verified
+
+- I read the whole run 350 job log (204 lines), and the router lines above. Runs 348 and 349 are
+  as recorded in `decisions/2026-10-30-renovate-first-run.md`'s follow-up: `/user` got 403 from
+  `tokenRequiresScopes`.
+- **The probe step, in the pinned image.** I extracted the step body from the YAML and ran it in
+  `ghcr.io/renovatebot/renovate:44.167.0` (`curl` 8.5.0 and `jq` are present) with a deliberately
+  **bogus** token. Every probe reported 401 with the "token VALUE" diagnosis, the scope-list read
+  fell back to a warning, and the step exited 1.
+- **The scope-list parser.** Against run 350's exact message format it reports `write:issue`
+  MISSING. Against a five-scope list it reports both OK. Against `all` it reports both OK.
+- **The lint guard.** It flags `renovatebot/github-action` in the pre-#84 `renovate.yaml`
+  (dfc432c, line 152). It reports nothing on the current workflows, and it ignores commented
+  lines. `bash -n ci/lint.sh` passes.
+- **Account facts, read-only.** `renovate-bot` is a collaborator with `write`, and the org is
+  public.
+
+## What I did NOT verify
+
+- **The probe with a real token. UNVERIFIED.** I never had the token. In particular, I have not
+  observed that `GET /api/v1/admin/orgs` gives renovate-bot's token a 403 with a `token scope=`
+  list. The source says the scope check runs before `reqSiteAdmin`. If the message format
+  differs, the step warns and does not fail.
+- **That five scopes are enough for a full non-dry run.** They cover every helper endpoint Renovate
+  44.167.0 calls, mapped to Gitea 1.24.3's route categories by reading source. Branch pushes go
+  over git-over-HTTPS with the token; I believe that needs write:repository, but I have not
+  observed it.
+- **Registry reads as renovate-bot.** `read:package` on a public org is expected to work. The new
+  probe is the first real test of it.
+- **Sensitive paths.** `.gitea/**` and `ci/**` are both sensitive. CI's `approval-policy` will block
+  until the operator posts `/approve-override` as a PR review.

+title: Renovate never started because its action needs a Docker daemon jobs here do not get; it now runs as the job container
+---
+
+## What changed
+
+**`.gitea/workflows/renovate.yaml`**: the job no longer uses `renovatebot/github-action`. The
+pinned Renovate image (`ghcr.io/renovatebot/renovate:44.167.0`, the same version the action was
+pinned to) is now the job's `container:`. A `run:` step calls `renovate-entrypoint.sh renovate`
+inside it. `actions/checkout` is gone, because Renovate clones the repo itself.
+`GITHUB_COM_TOKEN` is wired from a new **optional** secret, `RENOVATE_GITHUB_COM_TOKEN`. The step
+unsets it, and `RENOVATE_DRY_RUN`, when they evaluate to the empty string. The preflight also
+prints `renovate --version`, which proves the step ran inside the pinned image.
+
+**`renovate.json5`**: one comment now names `container.image` as the version pin, in place of
+`renovate-version`. The config itself is unchanged.
+
+### Why: the root cause
+
+Every run of the action died before Renovate started. That includes the operator's dispatch,
+run 343 (task 555, 2026-10-30 06:14 UTC), and the 11 scheduled runs before it (312–322). From
+run 343's log:
+
+    RENOVATE_TOKEN is present (value not printed).
+    [command]/usr/bin/docker run --env LOG_LEVEL ... --env RENOVATE_TOKEN=*** --env RENOVATE_CONFIG_FILE=/github-action/renovate.json5 ...
+    failed to connect to the docker API at unix:///var/run/docker.sock; check if the path is correct and if the daemon is running: dial unix /var/run/docker.sock: connect: no such file or directory
+    Error: The process '/usr/bin/docker' failed with exit code 1
+
+The action is only a wrapper around `docker run`. On this runner a job deliberately gets no
+Docker daemon (`decisions/2026-10-29-image-pipeline.md`): act_runner maps `docker_host` to `-` when
+`DOCKER_HOST` is `tcp://`, and the DinD daemon is privileged. So this was a
+platform-compatibility failure. The run never reached authentication, token scope, config or the
+network. **The re-minted token is not implicated, and nothing in this log can say whether its
+scopes are right.**
+
+A job `container:` needs no daemon. act creates it through the runner's DinD the same way it
+creates the default `ubuntu-latest` image, then `exec`s each step inside it. I checked this
+against gitea/act v0.261.2:
+
+- The job container's entrypoint is `/bin/sleep` (`run_context.go`). The Renovate image has
+  `/usr/bin/sleep`.
+- The step command files are written `0o666` (`step.go`), so the image's uid 12021 can write
+  `$GITHUB_STEP_SUMMARY`.
+- `HOME` comes from the image env.
+
+## What I verified
+
+- **The root cause.** I read all of run 343's job log (162 lines, job 0; job 1 is 404). It has one
+  error, quoted above, and no Renovate output at all. Runs 312–322 are all `failure` from the
+  `schedule` event.
+- **The config validates against the pinned tag.** `podman run ... ghcr.io/renovatebot/renovate:44.167.0
+  renovate-config-validator /tmp/renovate.json5` printed `Config validated successfully`. It also
+  printed the known migration diff for the top-level `docker` block.
+- **A dry run with the fix extracts and looks up dependencies.** This was a local reproduction. I
+  made a clean snapshot of this branch's tracked files. I ran it in a podman container of the pinned
+  image with entrypoint `/bin/sleep`, as the image's own uid 12021 with `HOME=/home/ubuntu`.
+  Inside it I `exec`ed the workflow step's `run:` body, extracted verbatim from the YAML, with:
+  - `RENOVATE_PLATFORM=local`, `RENOVATE_DRY_RUN=full` and `GITHUB_COM_TOKEN=` (empty, to
+    exercise the unset);
+  - a docker host rule for `gitea.home.keithjackson.dev` using the `gitea-admin` credential from
+    `~/.git-credentials`, passed through env and never printed.
+
+  The run exited 0 and logged `Dependency extraction complete`:
+  - flux 15 deps / 13 files
+  - github-actions 24 / 4
+  - kubernetes 131 / 67
+  - kustomize 2 / 2
+  - regex (both custom managers) 7 / 6
+  - **total 179 deps / 92 files**
+
+  It found **42 updates**: 29 kubernetes, 6 flux, 2 kustomize, 1 github-actions and 4 regex
+  `digest`. 7 of them are `major`.
+- **The `# renovate-digest:` lookups against the Gitea registry succeed.** All three
+  `/v2/token?scope=repository:home-network/<img>:pull` requests succeeded, and so did
+  `HEAD /v2/home-network/<img>/manifests/main`. They proposed `digest` updates for
+  `conformance/versions.env`, `infra/agent/versions.env`, `platform/pm-agent/configmap.yaml` and
+  `platform/pm-agent/deployment.yaml`, all of which carry the zero placeholder digest today. The
+  `kubernetes` manager's copies of those images report `disabled`, which is the intended effect of
+  the packageRule.
+- **The new pin is still maintained by Renovate.** The github-actions manager extracts
+  `ghcr.io/renovatebot/renovate:44.167.0` from `renovate.yaml` as depType `container`, and proposes
+  44.198.0.
+- **The `regex` vs `custom.regex` question from #73/#77 is closed.** Both custom managers produced
+  dependencies.
+- **Missing GitHub token.** The local run logged `GitHub token is required for some dependencies`.
+  That accounts for 17 deps skipped with `github-token-required`, which is why
+  `RENOVATE_GITHUB_COM_TOKEN` is offered as an optional secret.
+
+## What I did NOT verify
+
+- **The workflow on the real runner. UNVERIFIED.** My reproduction ran with podman, not
+  act_runner + DinD, and used `--platform=local`. The act behaviour (sleep entrypoint, `exec` as the
+  image user, 0666 command files) comes from reading the gitea/act v0.261.2 source, not from a run.
+  The first real evidence will be a `workflow_dispatch` after merge.
+- **The Gitea platform path and `RENOVATE_TOKEN`'s scopes. UNVERIFIED.** I have no access token, only
+  the `gitea-admin` password, which Renovate's Gitea platform cannot use. So these were not
+  exercised: platform init (`GET /user`, which needs `read:user`), repo clone, and the registry
+  lookups using the **token** with `read:package` rather than a password.
+- **Behaviour inside the schedule window.** A dispatch outside 03:00–06:00 America/New_York
+  (07:00–10:00 UTC during EDT) will extract and look up, but will log "not within schedule"
+  instead of `DRY-RUN: Would create ...` lines. I did not change this.
+- **Renovate as uid 12021 doing artifact updates** (for example helm lockfiles) on a real,
+  non-dry run. `--dry-run=full` does not run the tools.
+- **The self-bump.** Renovate will propose `ghcr.io/renovatebot/renovate` 44.167.0 → 44.198.0 as a
+  minor, which the default rule auto-merges. `.gitea/**` is a sensitive path, so it will in fact
+  wait for an administrator override. Nothing re-runs `renovate-config-validator` on that bump,
+  and no gate check runs the validator.
+- **No alert for "Renovate red every day".** That gap is still open. This failure ran for 12 days
+  without anyone noticing.
+- **Sensitive path.** `.gitea/**` is in `infra/gitea/approval-policy.json`, so CI's
+  `approval-policy` stage will block until the operator posts `/approve-override` as a PR review.

+title: Operator decision — the oauth2-proxy sidecar and Renovate's own version never auto-merge
+---
+
+## What changed
+
+`renovate.json5` gains two packageRules. Both set `automerge: false` and `addLabels: ["needs-review"]`.
+They sit after the auto-merge rule, so they override it at every update type. Each rule's
+`description` carries the operator's reason.
+
+1. **`quay.io/oauth2-proxy/oauth2-proxy`.** This is the single depName emitted for:
+   - `catalog/render.py` `OAUTH2_PROXY_IMAGE` (custom regex manager);
+   - the five rendered `apps/wave-*` sidecars;
+   - `platform/crafty/deployment.yaml` (kubernetes manager).
+
+   **Reason:** since v7.13.0, oauth2-proxy validates refreshed OIDC sessions against the access
+   token, not the id_token. Every sidecar sets `--cookie-refresh`, and that path is untested against
+   this Keycloak: the platform oauth2-proxy runs v7.15.5 without `--cookie-refresh`.
+   `render-golden` and `--selftest` pass on the bump, but both check rendered text, not the binary.
+2. **`ghcr.io/renovatebot/renovate`.** This is the job `container.image` in
+   `.gitea/workflows/renovate.yaml`. The rule also lists `renovatebot/github-action`, so a
+   reintroduction would be held too. It is not used anywhere today; `ci/lint.sh` rejects it.
+
+   **Reason:** nothing re-validates `renovate.json5` against the new version before it takes
+   effect. The 39.x `CONFIG_VALIDATION` failure is the precedent.
+
+## What I verified
+
+- **The config validates on the pinned 44.167.0.** `renovate-config-validator` printed
+  `Config validated successfully`. The migration diff is only the pre-existing top-level `docker`
+  block.
+- **The flag change is exactly the intended one.** I used Renovate 44.167.0's own
+  `resolveConfigPresets` and `applyPackageRules` to evaluate b4ff287's config and this branch's
+  config against the same updates (the local dry run of the #86 config). Exactly **2 of 29**
+  branch rows differ:
+  - `ghcr.io-renovatebot-renovate-44.x`: `automerge=true labels=` → `automerge=false labels=needs-review`;
+  - `quay.io-oauth2-proxy-oauth2-proxy-7.x`: the same change, and every upgrade in the branch
+    resolves `false`, the `catalog/render.py` one included.
+
+  The other 27 rows are byte-identical.
+
+## What I did NOT verify
+
+- **The three GitHub-hosted branches** in run 357 (`pin-dependencies`, `kubevirt-cdi`,
+  `intel-intel-device-plugins-for-kubernetes-0.x`) are not in the harness table: my local run has
+  no github.com token. Neither rule's package names can match them.
+- **A live Renovate run with this config.** The next debug-level dispatch should show
+  `needs-review` on both branches.
+- **The oauth2-proxy refresh path itself** remains untested. Exercising it on one app is the
+  review the label asks for.

+title: Renovate's first completed dry runs, audited; it would have opened red PRs for every app and missed the databases. Config fixed
+---
+
+## What changed
+
+**`renovate.json5` only.** Each change carries a comment quoting the measurement behind it.
+
+1. **Three new regex managers, so updates edit the SOURCE.**
+   - `catalog/*.yaml` `source.image`.
+   - `catalog/render.py` `OAUTH2_PROXY_IMAGE`.
+   - CNPG `imageName:` under `platform/` and `apps/`.
+
+   The first two match the rendered line's depName, so the catalog edit and the generated
+   `apps/wave-*` edit land in **one** branch.
+2. **`allowedVersions` mirroring each ServiceDefinition's `update.range`:**
+   - gitea/gitea `<2.0.0`
+   - nextcloud `<32.0.0`
+   - qbittorrent `<6.0.0`
+   - radarr `<6.0.0`
+   - sonarr `<5.0.0`
+   - semaphore `<3.0.0`
+
+   Plus CNPG postgresql `<17.0.0`, because a Postgres major is a migration, not a bump.
+3. **The blast-radius never-automerge list gains** `gitea/gitea`, `gitea/act_runner` and
+   `ghcr.io/cloudnative-pg/postgresql`.
+4. **HelmRelease range widening** (`matchManagers: flux`, ranged currentValue) is never
+   auto-merged and is labelled `range-widen`.
+5. **Majors need a Dependency Dashboard tick** (`dependencyDashboardApproval`) before a PR opens.
+6. **`flux` manager docker deps are disabled.** These are duplicates of `kubernetes` manager
+   extractions.
+7. **`velero/velero-plugin-for-aws` uses `semver` versioning**, so its RC pin can reach a stable
+   release.
+8. **`python` minors are not auto-merged.**
+9. **Two false comments are corrected.**
+   - Ranges "cap Renovate at patches": false, Renovate widens them.
+   - `nextcloud:31-apache` and `docker:27-dind` "cannot be maintained": false, they were.
+
+PR #85 is merged, so nothing here overlaps an open branch.
+
+### The audit: dispatch runs 353 (07:12 UTC) and 354 (07:23 UTC), on 593d0fa
+
+Both runs ended `success`, Renovate `"result": "done"`, `exitCode 0`. Both were at `info` level, so
+I reproduced the per-dependency detail with a debug-level local dry run of the same commit (see
+below).
+
+The runs were inside the 03:00–06:00 America/New_York window, so branches were processed:
+- run 353: 37 "Would commit" branches;
+- run 354: 40, because the operator had added `RENOVATE_GITHUB_COM_TOKEN` 9 s before it.
+
+Gitea's router log for the act-runner pod during both runs shows 317 2xx responses. The only
+non-2xx were all expected:
+- `/v2/` 401: the registry challenge;
+- `/admin/orgs` 403: the #85 scope probe, by design;
+- 6× `HEAD …/manifests/sha256:000…` 404: the placeholder digests.

+| # | Class | Count | Cause | Severity | Fix |
+|---|---|---|---|---|---|
+| 1 | App-image PRs edit only generated `apps/wave-*` | 9 branches | A ServiceDefinition has no `apiVersion`, so the `kubernetes` manager extracts 0 deps from `catalog/`. The oauth2-proxy sidecar is a Python constant (`catalog/render.py:132`) | **Real problem.** Every such PR fails `ci/render-golden.sh` (reproduced: rc 1 "GOLDEN DRIFT"), stays red and holds a PR slot | git (1) |
+| 2 | CNPG `imageName` untracked | 3 Clusters | The `kubernetes` manager reads `image:` only. The one tracked postgres line was the grant Job (`nextcloud-db.yaml:303`, "keep in step with spec.imageName") | **Real problem.** A real run bumps the Job and leaves the databases behind | git (1) |
+| 3 | Bogus or out-of-policy majors | 5 branches: gitea 28.2.0, qbittorrent 20.04.1, radarr 6.x, nextcloud 35, postgresql 18.6 | Odd legacy tags, plus `update.range` in `catalog/` not being read by Renovate | Risk if run for real: unmergeable PRs, which hold slots | git (2) |
+| 4 | Auto-merge of the merge gate's own host | gitea 1.24.3→1.27.3, act_runner 0.2.11→0.6.1, both "minor" | Not in the blast-radius list. A 0.x minor is breaking by semver | **Risk if run for real** | git (3) |
+| 5 | Range widening auto-merged | external-dns, headlamp (minor); longhorn (blast radius); kube-prometheus-stack (major) | Renovate widens `>=a <b`. The config's comment claimed the opposite | **Risk if run for real:** silently lets Flux adopt new minors | git (4, 9) |
+| 6 | Majors hold PR slots | 10 majors in run 354 against `prConcurrentLimit: 5` | Majors never auto-merge, so they stay open | Risk: starves auto-mergeable PRs | git (5) |
+| 7 | `Cannot find replaceString … alpine:3.22` (INFO) | 1 per run | The same HelmRelease `image:` line is extracted by `flux` and `kubernetes` (also the velero plugin) | Cosmetic. The branch is still right | git (6) |
+| 8 | velero-plugin-for-aws stuck on `v1.14.3-rc.2` | 1 dep, 0 updates | Docker versioning treats `-rc.2` as a suffix, so stable `v1.14.3` and `v1.14.4` never qualify | **Real problem** (silent) | git (7) |
+| 9 | python 3.13→3.15 as auto-mergeable "minor" | 2 files | Language runtime minor | Risk if run for real | git (8) |
+| 10 | `WARN GitHub token is required` | run 353: 5 packages, 17 deps | No github.com token | Real (they were unmaintained) | **operator, done:** run 354 has no WARN and adds `pin-dependencies`, `kubevirt-cdi`, `actions-checkout-7.x`, `major-github-artifact-actions` |
+| 11 | Floating or untagged images (`invalid-value`) | 4: jackett, plex `latest`; pihole, keycloak no tag | No version to compare | Real, already documented | none in git. Pinning by hand is an operator/PM decision |
+| 12 | `runs-on: ubuntu-latest` `invalid-version` | 11 | The github-actions manager extracts runner labels | Cosmetic, debug-only | none |
+| 13 | `Docker Manifest is unknown` (debug) | 3 | HEAD on the all-zero placeholder digests | Expected. Clears when the own-image digest PRs merge | none |
+| 14 | `Docker: error fetching data from DockerHub` 403 (debug) | 5 | Hub refuses `page=11`. Renovate already has the tags | Cosmetic. Updates were still found | none |
+| 15 | `Config migration necessary` | 1 | Top-level `"docker": {"enabled": true}` | Cosmetic, pre-existing | none (as before) |
+
+**Checked and fine:**
+- The 3 own-image digest updates were found in both runs. All 4 `# renovate-digest:` markers parse.
+- No marker failed to parse.
+- No package file is under `conformance/runs` or `tests`, nor is `DECISIONS-LOG.md`, `decisions/` or
+  any `*.sops.yaml` (77 package files checked).
+- `kubevirt-cdi` grouping works.
+- The schedule window behaved as designed.
+- Vulnerability alerts: none in either log.
+
+## What I verified
+
+- I read both job logs in full (132 and 129 lines), and the router log for 10.0.0.38 during both
+  runs.
+- **`renovate-config-validator` on 44.167.0**: `Config validated successfully`. The migration diff
+  is only the pre-existing `docker` block.
+- **Local dry runs.** Pinned image, `--platform=local`, debug, origin/main snapshot. "Before" is
+  593d0fa and "after" is this config; the GitHub-hosted deps were skipped in both.
+  - **Extraction:** `regex` went from 6 files / 7 deps to **19 files / 20 deps**. Every other
+    manager is unchanged: flux 15, github-actions 24, kubernetes 131, kustomize 2.
+  - **Branches:** 33 before, **29 after**. Removed: gitea-28.x, qbittorrent-20.x, radarr-6.x,
+    nextcloud-35.x and postgresql-18.x. Added: velero `v1.14.3-rc.2 → v1.14.4` (patch).
+  - **Gitea, qbittorrent, radarr, sonarr, semaphore and seerr branches** now each carry
+    `catalog/<svc>.yaml` + `apps/wave-*/<svc>.yaml`.
+  - **The oauth2-proxy branch** carries `catalog/render.py` plus the 5 rendered apps and
+    `platform/crafty`.
+  - **The postgresql-16.x branch** carries all three Clusters.
+  - The 2 flux docker duplicates report `disabled`.
+- **render==golden holds for the new branch shape.**
+  - In the toolbox, I applied the gitea branch edit (catalog + apps) and the oauth2-proxy branch
+    edit (`render.py` constant + 5 apps) textually. `./ci/render-golden.sh` reported
+    `all 10 onboarded service golden(s) reproduce`, rc 0.
+  - Negative control, the old shape with only `apps/wave-0/gitea.yaml` bumped: rc 1,
+    `GOLDEN DRIFT`.
+  - Both edits were reverted afterwards.
+
+## What I did NOT verify
+
+- **The effect of the automerge, label and dashboard-approval rules (3, 4, 5, 8). UNVERIFIED in a
+  run.** `--platform=local` stops before branch processing, so I saw only which updates exist, not
+  their merged flags. The matchers are standard (`matchPackageNames`, `matchManagers`,
+  `matchCurrentValue`, `matchUpdateTypes`). The next dispatch's debug log shows them per branch.
+- **`allowedVersions` under docker versioning** used Renovate's "Falling back to npm semver
+  syntax" path (16 debug lines). That it filters is shown by the five removed branches.
+- **render==golden for the other app branches** (qbittorrent, radarr, sonarr, semaphore, seerr). I
+  proved it only for gitea and oauth2-proxy. They have the same shape: one `source.image` line ↔
+  one rendered `image:` line.
+- **The `allowedVersions` rules duplicate `catalog/*/update.range`** and can drift from it. Nothing
+  checks them against each other. A lint comparing the two is the obvious follow-up.
+- **Any real (non-dry) run.** None has happened. PR creation, labels, auto-merge through Gitea's
+  API and the Dependency Dashboard issue are all unobserved.
+- **Sensitive path?** `renovate.json5` is not in `infra/gitea/approval-policy.json`, as far as I
+  know. CI's `approval-policy` result on the PR is the measurement.

+title: Renovate tracks the Keycloak operator (the real Keycloak version), never auto-merged; the catalog's phantom image is pinned as documentation and disabled
+---
+
+## What changed
+
+- **`platform/keycloak/kustomization.yaml`**: each of the three `keycloak-k8s-resources/26.0.6`
+  release URLs (two CRDs and `kubernetes.yml`) now has a
+  `# renovate: datasource=github-tags depName=keycloak/keycloak-k8s-resources` marker on the line
+  above it. That is the format the existing `custom.regex` marker manager parses (the kubevirt
+  pattern). A comment explains that these URLs are the Keycloak version. The `Keycloak` CR has no
+  `spec.image`, so the operator's `RELATED_IMAGE_KEYCLOAK` picks the server image.
+- **`renovate.json5`** has two new packageRules:
+  - **`keycloak/keycloak-k8s-resources`**: `groupName: keycloak-operator`, `automerge: false`,
+    `addLabels: [needs-review, blast-radius]`. A comment explains why. The operator, the CRDs and
+    the server are released in lockstep. The IdP gates SSO for every app and for kubectl. And
+    `passkey-reconciler.yaml` encodes Keycloak 26.0.6 Admin API shapes that the static gate never
+    exercises. Majors still go through the existing dashboard-approval rule.
+  - **`quay.io/keycloak/keycloak`**: `enabled: false`. Its only occurrences are in files that
+    deploy nothing.
+
+  The "STILL CANNOT FIX" comment also gains a one-line correction for keycloak.
+- **`catalog/keycloak.yaml`**: `source.image` changed from `quay.io/keycloak/keycloak` (no tag) to
+  `quay.io/keycloak/keycloak:26.0.6`. A comment says the image is DOCUMENTATION-ONLY and that the
+  operator chooses the real one. `apps/wave-1/keycloak.yaml` was re-rendered, which changes one
+  line.
+- **`platform/keycloak/README.md`**:
+  - Corrects the false claim "Renovate maintains the version". Until now Renovate could not see
+    the version.
+  - Adds a new section, **"Upgrading Keycloak: the operator IS the version"**. It lists the 26.0.6
+    assumptions in the passkey reconciler to diff against a new tag, and the post-merge checks.
+
+**The phantom: pin and disable, not delete.** `apps/wave-1/keycloak.yaml` is not listed in
+`apps/wave-1/kustomization.yaml`, and render-golden excludes it (`RENDER_GOLDEN_NOT_ONBOARDED`).
+Deleting it would still not be a no-op:
+
+- It is the fixture for the keycloak cases in `apps/wave-1/tests/app-slis.test.yaml` (the
+  StatefulSet-based `keycloak-down` rule). Those cases are discovered by the
+  every-PrometheusRule-in-apps/wave-1 convention.
+- Removing it means moving that rule and its tests to `platform/keycloak`. That is a separate
+  observability change, not a Renovate one.
+
+Pinning plus `enabled: false` changes one line in a file nothing applies. It cannot affect the
+cluster, and render-golden stays green.
+
+## What I verified
+
+- **Live state, prod, read-only kubectl, 2026-10-30.**
+  - Keycloak CR `keycloak` has an empty `spec.image`.
+  - The operator Deployment runs `quay.io/keycloak/keycloak-operator:26.0.6`, imageID
+    `sha256:8e3a1a56346f…`, with `RELATED_IMAGE_KEYCLOAK=quay.io/keycloak/keycloak:26.0.6`.
+  - `keycloak-0` and `keycloak-1` both run `quay.io/keycloak/keycloak:26.0.6`, imageID
+    `sha256:a93d22e13b86…`.
+  - There is no PrometheusRule containing "keycloak" in any namespace. This confirms the phantom
+    deploys nothing, including its `keycloak-down` rule (see the next section).
+- **`renovate-config-validator`** on the pinned `ghcr.io/renovatebot/renovate:44.167.0`:
+  `Config validated successfully`. The only migration note is the pre-existing `docker` block.
+- **Local dry run** (`RENOVATE_PLATFORM=local`, `RENOVATE_DRY_RUN=full`, debug, the same pinned
+  image, this worktree, with a GitHub token passed by environment variable; the token string
+  occurs 0 times in the log):
+  - The regex manager went to 21 files / 24 deps.
+  - `keycloak/keycloak-k8s-resources` was extracted three times from
+    `platform/keycloak/kustomization.yaml`, each at `currentValue 26.0.6`, datasource
+    `github-tags`, versioning `semver`.
+  - Each extraction has one update, `26.8.1`, updateType `minor`, and all three share **one**
+    `branchName: renovate/keycloak-operator`.
+  - `quay.io/keycloak/keycloak` was extracted from `catalog/keycloak.yaml` (regex) and from
+    `apps/wave-1/keycloak.yaml` (kubernetes) at 26.0.6, with `skipReason: disabled` and no
+    updates.
+- **Rule effects.** `--platform=local` does not print each branch's merged flags. So I ran
+  Renovate's own `applyPackageRules` (from `dist/util/package-rules` in the same 44.167.0 image)
+  over this `renovate.json5` for each case:
+
+  | Update | Result |
+  |---|---|
+  | operator minor 26.0.6 → 26.8.1 | `automerge:false`, `groupName:keycloak-operator`, labels `dependencies, automated-update, needs-review, blast-radius` |
+  | operator patch | same as the minor |
+  | operator major | `automerge:false`, `dependencyDashboardApproval:true`, labels add `breaking` |
+  | `quay.io/keycloak/keycloak`, catalog and rendered | `enabled:false` |
+  | control: sonarr patch | `automerge:true`, so the rule did not disable auto-merge globally |
+- **render-golden, host:** `render.py --selftest` passed, and `all 10 onboarded service golden(s)
+  reproduce`. Before the pin, the committed phantom was byte-identical to the canonical render. I
+  re-rendered it after the pin.
+- **Toolbox gate** (commit 24db269, worktree with the ENGINE shim mounting `.git` and the spec
+  repo, `DEV_KUBECONFIG=/dev/null`): **rc 3**.
+  - The only stage that did not run is **`gitea-settings`**.
+  - spec-immutability, decisions-log, lint, l0, render-golden, l1 and approval-policy all passed.
+  - L2/L3 `conformance` scaffold-skipped, as expected.
+  - **Not green.**
+- **Sensitive paths:** none touched (checked against `infra/gitea/approval-policy.json`), so no
+  `/approve-override` is needed.
+
+## What I did NOT verify
+
+- **A real Renovate run.** No PR was opened by Renovate. The labels and `automerge:false` are
+  proven by Renovate's own matcher, not by an opened PR.
+- **That 26.8.1 is safe to adopt.** I did not diff 26.0.6 against 26.8.1. That includes the
+  reconciler's assumptions: `recurseExecutions` displayName, `updateExecutions`, the
+  `RpEntityName` guard, `requiredActions` REPLACE, and config aliases. The README section lists
+  them for whoever reviews the first bump PR. It also says to take or confirm a fresh CNPG backup
+  first, because a server minor may migrate the schema.
+- **FINDING, not fixed: Keycloak has no deployed "IdP down" alert.** The `keycloak-down` SLI rule
+  exists only inside the undeployed `apps/wave-1/keycloak.yaml`. promtool tests it, but it is not
+  on the cluster: there is no keycloak PrometheusRule live. Separately, because that file exists,
+  `render.py --emit-waves` would treat keycloak as onboarded. It would then add a Deployment named
+  `keycloak` beside the operator's StatefulSet (the known `--emit-waves` hazard). The proper fix is
+  a separate PR: move the rule and its tests into `platform/keycloak`, then delete the phantom.
+- **The catalog tag can drift.** Nothing ties `catalog/keycloak.yaml`'s documentation tag to the
+  operator URLs. It must be updated by hand after an operator bump, and the README says so.
+- **Concurrent branches** `fix/renovate-hold-auth-and-self` and `feat/pin-pihole-jackett-plex`
+  also edit `renovate.json5`. Neither had merged when I checked. A rebase may be needed.

+- No other values changed. `PM_DRY_RUN` stays "false". `PM_DECISION_MAX_TURNS` is not set, so

+- PR #99's merge commit is `466f63ec3c3df968a1dab25a8811dcd41961efde` (origin/main HEAD at

+- The Gitea Actions tasks API shows the `images` workflow (images.yaml) on that commit as

+## What changed
+
+- `platform/pm-agent/configmap.yaml`: `PM_DRY_RUN` `"true"` -> `"false"`. The operator approved
+  this after reading the dry-run triage of issue #97. `PM_REQUIRE_LABEL: agent`,
+  `PM_MAX_ACTIVE_WORKERS: 2`, `PM_MAX_NEW_WORKERS_PER_CYCLE: 1`, the worker image digest and every

+- Egress: `default-deny` NetworkPolicy exists. CiliumNetworkPolicies `pm-agent-allow-egress`

+title: Bump pm-agent to the run-383 agent-runner digest by hand; Renovate saw it but the schedule withheld it
+---
+
+## What changed
+
+`platform/pm-agent/deployment.yaml` (the dispatcher `image:`) and `platform/pm-agent/configmap.yaml`
+(`PM_WORKER_IMAGE`) move:
+
+- from `agent-runner@sha256:c4eba5b3c508bf456a03391ac76f8275e7ea28a829da1450d99f6f6f25c6eb42`, the
+  run-340 publish;
+- to `agent-runner@sha256:df36d9b7fef56d141220a387f64fb864cede8e5af30513ebfeb3ab566d3f771d`, the
+  images run 383 publish of ddd04d4.
+
+Both `# renovate-digest:` markers are unchanged, directly above their values.
+
+`pm-agent.homelab.keithjackson.dev/config-generation` goes `"2"` → `"3"`. That is the convention in
+`deployment.yaml`'s own comment: "bump it in the same commit as a change to configmap.yaml". The
+image change alone would roll the pod, but the convention is followed regardless.
+
+No `*.sops.yaml` file is touched. Branched from 06d4a9a, which already contains the operator's #95.
+
+### Why Renovate did not do this: the schedule, not a config defect
+
+- **Run 385** (dispatch, 2026-10-31 16:14 UTC, on ddd04d4) was a **real** run. It logged
+  `Deleting orphan branch (… renovate/pin-dependencies)`, not a `DRY-RUN:` line. It ran at **12:14
+  America/New_York**, outside `"schedule": ["after 3am and before 6am"]`, so it created and updated
+  no branch.
+- **The lookup DID see the new digest.** Dependency Dashboard issue #91 lists, under **"Awaiting
+  Schedule"**:
+  `chore(deps): Update gitea.home.keithjackson.dev/home-network/agent-runner:main Docker digest to df36d9b`.
+- **Nothing else blocked it.** There are no open Renovate PRs and no `renovate/*` branch on Gitea
+  (111 branches listed across all pages). The previous agent-runner PR, #90 (to c4eba5b), was
+  auto-merged by renovate-bot at 08:22 on 10-31. No PR limit was hit, and digests are not
+  dashboard-approval gated.
+- **The registry, read-only, with Docker/OCI `Accept` headers:**
+  - `HEAD …/agent-runner/manifests/main` → `docker-content-digest: sha256:df36d9b7…771d`
+  - `HEAD …/agent-runner/manifests/sha-ddd04d460ef6` → the same digest.
+
+**Without this PR** the next scheduled run (08:15 UTC, 04:15 EDT) would open it, and it would
+auto-merge as a `digest` update. Ticking that "Awaiting Schedule" checkbox on #91 makes the next
+run of any kind create it out of schedule.
+
+### Found on the way: Renovate's labels have never been applied
+
+- The repo has exactly one label, `agent`. The org has none.
+- Every Renovate PR so far (#89, #90, #92, #93) was created with `"labels": []`.
+- On Gitea, Renovate drops a label that does not exist in the repo. So `needs-review`,
+  `blast-radius`, `range-widen`, `own-image`, `dependencies`, `automated-update`, `breaking` and
+  `ci-tooling` are never attached.
+- The **automerge flags still work.** Only the labels, the visible review signal, are missing.
+- **Operator fix:** create those labels on the repo. This was not changed here.
+
+## What I verified
+
+- **The new image carries the fix.** I fetched both images' layers read-only from the registry and
+  read `/etc/pm-agent/worker-job-template.yaml` from each (`infra/agent/Containerfile:116` copies
+  it there):
+  - df36d9b's has `imagePullSecrets:` / `- name: pm-agent-registry`;
+  - c4eba5b's has no `imagePullSecrets` at all.
+
+  This matches `infra/agent/worker-job-template.yaml:76-77` at ddd04d4.
+- **`main` = `sha-ddd04d460ef6` = df36d9b**, both measured.
+- **No other file references c4eba5b.** No admission policy pins it.
+- **No override is needed.** `infra/gitea/approval-policy.json` lists only `platform/kyverno/**`
+  under `platform/`, so `platform/pm-agent/**` is not sensitive.
+- I read the whole job logs of runs 362, 367 and 385.
+
+## What I did NOT verify
+
+- **That the rolled dispatcher starts on df36d9b and that a worker Job is admitted.** That needs
+  Flux to apply this and a real dispatch. Both are operator actions.
+- **That the `pm-agent-registry` Secret exists and decrypts in-cluster** (#95's sops file). I did not
+  read it.
+- **That Renovate will treat this hand bump as current.** It should: its next lookup finds
+  `main` == the pinned digest, so it proposes nothing and drops the dashboard entry. Not observed.

+title: pm-agent triage fails with "claude exited 1:" and no message; log the CLI's stdout envelope so the cause is visible
+---
+
+## What changed
+
+- `infra/agent/pm-dispatch.py`, `ask_pm()`: on a non-zero exit the error now comes from a new
+  `describe_cli_failure()`, not from `proc.stderr` alone. With `--output-format json` the CLI
+  reports its own failures as the result envelope on **stdout** and writes nothing to stderr,
+  which is why both failures today logged `claude exited 1: ` with an empty message. The new
+  line carries the envelope's `subtype`, `is_error`, `api_error_status`, `num_turns`,
+  `duration_ms`, `total_cost_usd`, `stop_reason`, its `result`/`error` text, and the tails of
+  stdout and stderr. It names silence explicitly when both streams are empty.
+- `redact()`: everything in that message, and in `extract_decision()`'s "no decision object"
+  error, passes through it. It covers `sk-ant-…`, `Bearer`/`token` values, and `user:pass@` in
+  both `http://` and `https://` URLs.
+- `PM_DECISION_MAX_TURNS`: a new knob. It defaults to 1, today's value, so behaviour is
+  unchanged, and it is bounded to 1–5. If the newly visible envelope says `error_max_turns`,
+  the remedy is a ConfigMap change rather than another image build. Documented in
+  `platform/pm-agent/README.md`.
+- Selftest: four new assertions. They cover an empty stderr with the cause on stdout, a
+  stderr-only failure, total silence, and redaction.
+
+## What I verified
+
+- **Timeline (Loki, `{namespace="pm-agent"}`, and `kubectl logs`):**
+  - **16:37:38 to 16:38:00**: pod `pm-agent-898fd8f5f-dp5hs`, image **c4eba5b3**,
+    config-generation 2, dry run. It triaged #97 in **22 s**, logged `PM says comment`, and
+    posted the 16:38:00Z comment. The thread then held only the issue body.
+  - **16:43:09 to 16:44:00**: pod `pm-agent-f7c9b7fcf-j8mzn`, image **df36d9b7**,
+    config-generation 3, **still dry run**. It logged `claude exited 1: ` with an empty
+    message after **51 s**.
+  - **16:55:42 to 16:56:36**: pod `pm-agent-7796db8bcb-p5dsm`, df36d9b7, config-generation
+    4, live. The same empty failure, after **54 s**.
+  - The only successful triage ever was the 16:38 one. Every earlier `898fd8f5f`/`5db55d558c`
+    log line is a startup crash (Gitea `GET /user` 401), not a triage.
+- **Going live is NOT the cause.** The first failure happened in dry run. `ask_pm()` has no
+  dry-run branch: the prompt, flags, tools (`--tools ""`) and cwd are identical in both
+  modes. `PM_DRY_RUN` gates only `create_job()`, which runs after the model has answered.
+- **Ruled out, with evidence:**
+  - **Timeout**: 51 to 54 s against a 900 s limit, and a timeout raises `TimeoutExpired`,
+    not rc 1.
+  - **Budget cap**: the PM call passes no `--max-budget-usd`.
+  - **Prompt size**: the thread is the issue body (293 chars) plus three comments
+    (1871 + 404 + 77 chars), and the persona is 8 KB.
+  - **Writable HOME**: HOME=`/workspace` (emptyDir), and `CLAUDE_CONFIG_DIR=/workspace/.claude`
+    was written at 16:56.
+  - **Egress**: a TLS 1.3 handshake to `api.anthropic.com:443` from the dispatcher pod
+    succeeds in 0.06 s.
+  - **Model name and CLI version**: the same `claude-opus-5` and CLI 2.1.285 succeeded at
+    16:38. Between c4eba5b and df36d9b, `infra/agent/` differs only by a template selftest
+    assertion and the toolbox base digest.
+- **A hint, not proof:** `/workspace/.claude/.claude.json` in the live pod has
+  `cachedExtraUsageDisabledReason: 'out_of_credits'`. No token was read or printed.
+- Offline selftest: `PM_SELFTEST=1` against the worktree's template and persona prints
+  `selftest OK`, including the 4 new assertions.
+- Toolbox gate: see the PR description for the rc and the stages that were skipped.
+
+## What I did NOT verify
+
+- **The root cause. UNVERIFIED.** The CLI's own message was discarded, `--no-session-persistence`
+  leaves no transcript, and I did not run `claude` in the pod. The candidates still open:
+  - **Usage or rate limit on the subscription seat.** The seat is shared with the operator's
+    interactive use. The `out_of_credits` extra-usage flag fits this. So does a ~50 s run,
+    which matches the CLI exhausting its 429/529 retries.
+  - **`error_max_turns`.** With `--max-turns 1` and `--json-schema`, an answer that fails the
+    schema cannot be retried. The failing thread now invites `implement` (a branch plus a
+    long brief), where the 16:38 one produced a short `comment`. ~50 s is about two
+    generations of the 22 s success.
+- **The 17:11 retry will NOT reveal the cause.** It runs the old image, which still discards
+  stdout. The cause becomes visible only after this PR merges, CI re-publishes agent-runner,
+  and a follow-up PR bumps the dispatcher digest (`deployment.yaml` and the `PM_WORKER_IMAGE`
+  in `configmap.yaml`, plus a `config-generation` bump).
+- That the CLI's error envelope carries exactly these key names. The parser takes whichever
+  keys are present and falls back to raw tails.

+## What changed
+
+- `infra/devcontainer/versions.env`: new `VELERO_VERSION=1.18.2`, with a comment explaining that
+  the CLI and server are version-coupled, so this pin follows the server and is not bumped on

+  no checksum check, which matches the other tools in that file (none of them verify one).
+  `velero=` is recorded in `/etc/dev-toolchain-versions`. The verify stage now checks that
+  `velero` is on PATH, and `check velero v${VELERO_VERSION}` asserts the output of
+  `velero version --client-only`.
+- `infra/devcontainer/build-image.sh`: `VELERO_VERSION` added to `BUILD_ARGS`. CI reads that
+  list generically through `--print-build-args` (`.gitea/workflows/scripts/images.sh`), so
+  **no sensitive path (`.gitea/**`, `ci/**`) was touched**.
+- `infra/devcontainer/README.md`: added a Backups row to the tool table.

+  `velero backup describe --details` / `backup logs` example run through dev.sh.
+
+## What I verified
+
+- Live server version, read-only: `kubectl --context k3s-prod -n velero get deploy velero`
+  shows image `docker.io/velero/velero:v1.18.2`, and HelmRelease `velero` has
+  lastAttemptedRevision `12.2.3`.
+- Local build: `IMAGE=localhost/home-k3s-dev:velero-wt ./build-image.sh` returned rc 0. The

+- Smoke test with that image against prod (read-only): `velero version` reports Client v1.18.2

+- Recurring warning (reported only, not fixed): every daily backup since
+  `velero-daily-20261031030050` has 1 warning. Backups up to 20261030 have 0. The warning text is:
+  `gitea-actions: resource: /pods name: /act-runner-5944dfdfb8-69bvq message: /Skip pod volume
+  data error: /pod is not in the expected status, ... phase=Failed: pod is not running`.

+  2026-10-30T08:26Z. The running runner is `act-runner-fc597f6b5-vsvkl`. So the warning comes from a

+  `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

+  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.

+## What changed

+`conformance/tests/l0-static/internal-services-publish-no-public-dns/check.sh` gains assertion
+(8). The check is already whole-repo-scoped, so it runs on every gate.
+
+- **(8a)** `platform/externaldns/helmrelease.yaml` must set `values.annotationPrefix` explicitly,

+- **(8b)** `extraArgs` must not carry `--annotation-prefix` or `--enable-legacy-annotation-prefix`,

+- **(8c)** Every external-dns-looking annotation key under apps/, platform/ and runbooks/ must use

+- **(8d)** catalog/render.py must emit no external-dns key under any other prefix.
+
+`CONTROLLER_KEY` and `HOSTNAME_KEY` are now derived from `ANNOTATION_PREFIX`. The Service
+inventory matches any external-dns prefix variant, not only the alpha one.
+
+Why: on 2026-11-07, external-dns v0.23.0 (whose default prefix is GA) ignored every alpha
+annotation. Assertions (1) to (3) stayed green, because they prove the annotations are present,
+not that the controller reads them. See `decisions/2026-11-07-public-dns-wan-a-record.md`.
+
+This branch is stacked on `fix/public-dns-wan-a-record` (PR #140). Without that fix, (8a) fails,

+  access or a vendored chart in L0.

+  `/approve-override`. The agent did not post one.

+title: The PM agent can be @-mentioned on a pull request — an EXPLICIT mention is the only trigger, reply only, shipped OFF
+---
+
+## What changed
+
+Issue #116 asked for the PM agent to react when it is `@`-mentioned on a pull request: read
+the PR, the changes and the thread, and reply in that thread. This branch implements the
+**trigger, context assembly, dispatch and reply** half. The change-authoring half (the
+operator's point 6 — revise an agent-owned branch versus open a fresh branch/PR against
+`main`) is deliberately absent and wants its own issue, as the PM said on the thread.
+
+### Revised 2026-11-07: continuation removed, an explicit mention is the only trigger
+
+The first version of this branch carried a **continuation** rule: once a thread held a
+mention, every later non-bot comment in that thread triggered a run with no second mention.
+The operator withdrew that requirement after reading the first PR description:
+
+> Since there is no threads and the PR comments are flat, then the pm-agent should be looking
+> for explicit mentions rather than a single mention and continued scrapping of comments
+> within the PR in perpetuity
+
+Read with their earlier *"the 'same thread' requirement was based on my assumption that
+comments can be hierarchical. If not, then disregard"*, the requirement is **withdrawn, not
+relocated**. So the arming state is gone, in both code and fixtures:
+
+- `plan_pr_replies` no longer carries an `engaged`/armed flag. A comment is answered iff
+  (1) it is not the bot's own, (2) no earlier reply of the bot's marks it answered, and
+  (3) it explicitly mentions the bot account. Nothing a comment's neighbours say can make it
+  actionable, so a comment with no mention produces **no reply and no model call**.
+- Applied **uniformly** — conversation comments, review bodies and inline review comments.
+  Inline comments *are* genuinely threaded in Gitea, and keeping continuation for them alone
+  was considered and rejected: it would be a second rule the operator did not ask for, and
+  the brief said to stop and ask rather than invent a middle rule. Nothing turned out to be
+  load-bearing on the arming state for the inline path (the inline path keys replies off the
+  (path, position) group, which is a *destination*, not a trigger), so there was nothing to
+  stop and ask about.
+- Thread identity survives, but **only as a reply destination**. "What counts as the same
+  thread" needed a policy while it was part of the trigger; now it only answers "where does
+  this reply go", and the two answers are Gitea's own: the conversation, or the (path,
+  position) group.
+- `reason` on a plan is now always `"mention"`. The field is kept because it is what the log
+  line and `PM_PLAN` print as *why you are running*, and the selftest asserts across every
+  fixture that no plan ever carries another value — a second value would mean a second
+  trigger had come back.
+- **What a mention still batches:** two *unanswered* mentions in one thread are one reply
+  naming both keys, because the at-most-once-reply model is per reply, not per mention.
+  Comments sitting between them are neither answered nor keyed.
+- The PM persona now tells the PM to **answer as if its reply is the last word it will see**,
+  and to ask the human to tag it again if it needs something back — under the old rule it
+  could end a reply with a question and expect the answer to reach it. It will not.
+
+Kept untouched, as the brief required: the in-reply idempotency marker and the
+at-least-once-decision / at-most-once-reply failure model; the self-authored filter as the
+first check; the hostile-payload fencing and the untrusted banner; `PM_PR_MENTIONS: "false"`,
+`PM_PLAN`, `PM_DRY_RUN` implying plan mode and the two-step rollout; the `/notifications`
+query with its fallback and the `read:notification` scope note; `PM_PR_DIFF_MAX_CHARS` and
+its default. **Context assembly is unchanged** — "explicit mention required" governs what
+triggers a run and what gets replied to, not how much the model sees, so the payload still
+carries the PR, the changed files, the diff and the whole comment list. The only payload
+edit is a line telling the PM that comments which do not mention it are context, not
+questions put to it.
+
+**The dispatcher was not structured the way the brief guessed, and that is worth recording.**
+The brief expected the poll loop under `ci/**` and/or `.gitea/**`. It is not there: it is
+`infra/agent/pm-dispatch.py`, a long-running Python program in the pm-agent Deployment
+(`platform/pm-agent/`). `ci/**` and `.gitea/**` are the merge gate and have nothing to do
+with it. **So this PR touches no approval-policy sensitive path** — I checked every changed
+path against `infra/gitea/approval-policy.json` by hand (see "What I verified") — and the
+`ci/approval-policy.sh` stage should pass on a green gate without a human review. The PM's
+own warning on the issue that the PR would sit red was an honest guess from an unverified
+belief about where the code lived; it was wrong, and nothing about the change needed to move
+to make it so.
+
+There *was* a poll loop to extend, so no architecture was improvised.
+
+`infra/agent/pm-dispatch.py`:
+
+- A second, independently-guarded pass per poll — `cycle_pr_mentions()`, called from `run()`
+  rather than from `cycle()`. Two reasons: the issue cycle returns early at the worker cap
+  and a mention creates no worker, so it must not be suppressed by a cap it cannot
+  contribute to; and a Gitea failure on one path must not silence the other.
+- **Discovery** (`discover_pr_candidates`). Tries Gitea's notification list for the bot
+  account — one bounded call, which is the "way to check for '@'s for the bot account
+  instead of scouring the entire pull request list" the operator asked for — and falls back
+  to listing open pull requests. Mode is a knob (`auto` / `notifications` / `pulls`), and
+  which query answered is logged every cycle. **A 401/403 is handled as its own case**
+  (`GiteaForbidden`) because on this service it is almost certainly a token scope, not a bug:
+  `/api/v1/notifications` sits behind Gitea's `notification` scope category and the bot's
+  token is minted `read:user, write:repository, write:issue, read:package`. The log names
+  `read:notification` as the remedy instead of reporting "no mentions found".
+- **Detection** (`normalize_pr_entries`, `plan_pr_replies`) — pure functions over normalized
+  comments, so the parts that must be provable offline are provable offline. Reads all three
+  Gitea resources: conversation comments (`/issues/{n}/comments`), review bodies
+  (`/pulls/{n}/reviews`) and inline review comments (`.../reviews/{id}/comments`).
+- **Context assembly** (`render_pr_thread`) — PR title and body, the changed-file summary,
+  a bounded diff, the full thread being answered with the anchor comment marked, and the
+  surrounding comments. Every field that came from a person goes through a single new
+  `fence()` helper under an explicit untrusted banner; `render_thread` was refactored onto
+  the same helper, which removes a twice-retyped `.replace("```", "`` `")`.
+- **A narrowed decision shape.** `PR_ACTIONS = ("comment", "decline")` and
+  `PR_DECISION_SCHEMA` with **no `branch` and no `brief` property at all** — the PM has no
+  field in which to ask for work. `handle_pull()` refuses anything outside that set (and
+  still marks it answered, so an unusable decision costs one decision rather than repeating
+  forever), and nothing on this path calls `build_job()`.
+- **Replying in the thread.** Conversation threads get an issue comment. Inline threads get
+  a one-comment review (`POST /pulls/{n}/reviews`, `event: COMMENT` — never `APPROVE`),
+  which is the only way Gitea creates an inline comment; if Gitea refuses it the reply falls
+  back to the conversation naming the file and position, because a mention answered in the
+  wrong place is better than one answered nowhere.
+- **`PM_PLAN`** — discover, assemble, print the exact payload and the exact thread it would
+  post into; ask no model, post nothing. Setting it also enables the path, so it is one knob
+  to look before leaping. `PM_DRY_RUN` implies it (see "the decision I made" below).
+
+`infra/agent/testdata/pr-mention-fixtures.json` (new) — 18 fixture cases driving the trigger
+logic from `PM_SELFTEST=1 pm-dispatch`, covering the six the brief required plus twelve edges.
+The three cases that asserted continuation are **inverted rather than deleted**, so the old
+behaviour cannot creep back unnoticed, and three were added for the revised rule.
+`infra/agent/Containerfile` COPYs them into the **verify stage only** (test data has no
+business in the shipped image) and the selftest **fails rather than skips** if it cannot find
+them. `infra/agent/pm-persona.md` gains a "When you are reading a PULL REQUEST" section, and
+the selftest asserts it is there — without it the PM would be answering a mention while still
+believing it may pick `implement`.
+
+`platform/pm-agent/configmap.yaml` adds the knobs with `PM_PR_MENTIONS: "false"`;
+`deployment.yaml` bumps `config-generation` 5 → 6 in the same commit, as that file requires.
+`platform/pm-agent/README.md` and `runbooks/pm-agent.md` document the path, the token scope,
+the plan mode and six new log lines.
+
+### The decisions made explicitly
+
+**The trigger.** Settled by the operator rather than by me: an explicit mention, and nothing
+else. See the revision section above. The earlier back-and-forth about what "the same thread"
+means for a flat comment list is moot — the question only existed because continuation needed
+a notion of sameness, and there is no continuation.
+
+**Idempotency ordering.** The marker lives *inside the reply the PM posts*
+(`<!-- pm-agent:replied-to=comment-9001,review-comment-77 -->`), which makes it one atomic
+write with the reply and therefore impossible to get out of step with it. The failure mode
+chosen, deliberately, is **at-least-once model call, at-most-once reply**: a crash before
+posting costs one repeated decision; a crash after posting is a no-op because the marker is
+already in the thread; and a POST that errors while Gitea actually created the comment is
+also a no-op, because nothing is retried inside the cycle and the next cycle re-reads the
+list. A mention is therefore never silently dropped and a reply is never duplicated. The
+rejected alternative — write a marker *before* asking the model — buys cheapness by making a
+crash swallow the mention with nothing in the thread saying so. `PM_PR_COOLDOWN_SECONDS`
+(900s) bounds the cost of the repeat, which is why paying it is the cheap side of the trade.
+
+**Loop prevention.** With no author gate (operator answer 3: *"anyone can talk and have the
+agent work"*), any passer-by can start a run, so a bug that let the bot's replies count as
+triggers is an unbounded loop anyone could light. The self-authored check is the first thing
+`plan_pr_replies` does with each comment and it is structural — a bot-authored comment can
+only ever *clear* work, never create it, so a reply of ours containing our own handle is
+inert. The posted reply additionally never contains `@`-the-bot. Fixture (c) is that case and
+the selftest asserts the second guard too. Dropping continuation narrows this surface
+further: a reply is now reachable only from a comment that spells the handle out, and the
+bot's own output never writes it, so the guard is doubled rather than relied upon.
+
+**Why it ships off.** Not one call on this path has been made against the live Gitea, and
+the endpoint it most wants is expected to be refused on today's token. `CLAUDE.md` §2b is
+explicit that this repository is not evidence about anything live, and the service's own
+rollout precedent is a staged one (`PM_DRY_RUN=true` for a day, `PM_REQUIRE_LABEL=agent`).
+Shipping it on would be asserting it works. `PM_DRY_RUN` was also made to imply `PM_PLAN`,
+because the runbook sells `PM_DRY_RUN` as "stop it taking new work" and a path that kept
+posting replies under it would be a footgun — and on this path the reply *is* the action
+under test, and it also carries the idempotency marker, so posting it would make a dry run
+not dry.
+
+No requirement ID is claimed. The brief is right that nothing in the `R-*` set covers agent
+tooling, and inventing one would be worse than the gap.
+
+## What I verified
+
+**The offline selftest, run in this container, exit 0.** 95 assertions, all passing:
+
+    PM_SELFTEST=1 PM_WORKER_JOB_TEMPLATE=infra/agent/worker-job-template.yaml \
+      PM_PERSONA_FILE=infra/agent/pm-persona.md python3 infra/agent/pm-dispatch.py
+    -> selftest OK, rc=0
+
+`PM_PERSONA_FILE` has to be named because this worker container's own image is older than
+this branch, so the baked `/etc/pm-agent/pm-persona.md` is the pre-#116 copy and the
+"persona states" assertion fails against it. In the shipped image the Containerfile COPYs
+the branch's persona to that path and the override is unnecessary.
+
+All 18 fixture cases pass, including the six the brief named: (a) a mention in a PR
+conversation comment is detected; (b) a mention in an inline review comment is detected as
+its own thread; (c) a bot-authored comment is ignored *including when it contains the bot's
+own handle*; (d) an already-marked comment id is skipped; (e) a conversation follow-up with
+no mention is **not** actionable even after the bot replied; (f) an unrelated comment on an
+unrelated PR triggers nothing.
+
+The cases that pin the revised rule:
+
+- **(e), (m), (l) — inverted, not deleted.** (e) a conversation follow-up after a reply, (m)
+  an inline follow-up in a thread the bot has already replied in, and (l) an unmentioned
+  inline comment on a pull request whose conversation was answered: all three now expect
+  **no reply at all**. (m) is the deliberate one — an inline thread is genuinely threaded in
+  Gitea and still gets no continuation.
+- **(i) — the burst shape the operator described.** Three comments, only the first mentioning
+  the bot: exactly **one** reply, keyed to the first comment only. The other two are carried
+  into the payload as context and are not answered.
+- **(q) — the consequence that is now closed.** A once-mentioned-and-answered pull request
+  then gets comments from `renovate` and `gitea-actions`: no reply.
+- **(p)** two *unanswered* mentions in one thread are one reply naming both keys; **(r)** a
+  fresh mention after an answered one gets its own reply, keyed only to itself, so a mention
+  is repeatable; **(o)** a comment made before the mention is still not pulled in.
+- Three assertions over **every** fixture at once, so a single case drifting cannot hide the
+  regression: every plan's `reason` is `mention`, every comment answered matches the mention
+  pattern, and no bot-authored comment is ever answered.
+
+Also still passing, unchanged: `@pm-agent-worker` and `[email protected]` (and
+`@pm-agentx`, `mail:foo@pm-agent`, `@pm-agent.worker`) are **not** mentions — which matters
+more now that the mention is the only trigger; a marker pasted by a non-bot author does not
+suppress a mention; a mention in a review *body* is a conversation trigger; two inline
+threads on one file stay separate with the newest-anchored one taken first; a position-less
+inline comment still lands in a stable thread.
+
+Also asserted: the reply carries a marker for every key it answers and contains no
+`@pm-agent`; the refusal comment is marked too; `PR_ACTIONS` is exactly `comment`/`decline`
+and a subset of `ACTIONS`; `PR_DECISION_SCHEMA` has no `branch`/`brief` and
+`additionalProperties: false`; `fence()` breaks an embedded triple backtick rather than
+dropping it; the assembled payload on a hostile PR (a body *and* a diff that each try to
+close the fence and issue orders) has balanced fences, carries the banner twice, and quotes
+the hostile text verbatim inside a fence; truncation keeps both the head and the tail.
+
+**The dispatcher plumbing the selftest does not reach, re-exercised against a stub Gitea
+after the revision** (a throwaway script under `$TMPDIR`, not committed; 26 assertions, all
+passing). Measured:
+
+- discovery resolves a notification subject URL to index 120 and reports source
+  `notifications`; a `GiteaForbidden` from `/notifications` falls back to `open-pulls`; in
+  `notifications`-only mode it returns `([], 'notifications-unavailable')` rather than
+  silently widening into the scan the operator rejected;
+- plan mode printed the payload and posted **nothing** for four fixtures;
+- case (a) posted into the **conversation** carrying marker `comment-9001`, and case (b)
+  posted **inline** on `infra/agent/pm-dispatch.py` position 42 carrying marker
+  `review-comment-7701` — so the reply still goes back where the mention was made;
+- case (i) (burst, only the first mentions) produced exactly one reply whose marker names
+  **only** `comment-9070`, and its payload still carried comments 9071 and 9072 as context;
+- cases (e), (m), (l) and (q) produced **no reply and no model call** — the stub counted zero
+  calls into `ask_pm_pr` across all four, which is the "no reply and no model call" half of
+  the brief's done-criterion measured rather than asserted;
+- case (p) produced one reply whose marker names both `comment-9100` and `comment-9102`;
+- an out-of-vocabulary action (`implement`) was refused with a marked explanatory comment and
+  no Job;
+- the rendered payload says `why you are running: **mention**` and carries the line telling
+  the PM that unmentioned comments are context, not questions put to it.
+
+**The merge gate, in this container, re-run after the revision:**
+
+    ./ci/gate.sh   ->   exit 3 (UNDETERMINED)
+    Stages that did not run: spec-immutability gitea-settings
+    diff base: origin/main @ 5b484f6b7884 ... HEAD @ 2fdb95393cc0
+
+Nothing failed. Those are the two skips `CLAUDE.md` §3 names as expected here — the sibling
+spec repo is not reachable from the cluster and `SETTINGS_API_TOKEN` exists only in CI — and
+they are the *only* two. `decisions-log`, `lint`, `l0`, `render-golden`, `l1` and
+`approval-policy` all reported green.
+
+**That this PR touches no sensitive path**, checked path by path against the
+`sensitive_paths` globs in `infra/gitea/approval-policy.json`: the changed files are under
+`infra/agent/`, `platform/pm-agent/`, `runbooks/` and `decisions/`. `infra/agent/**` is not
+in the list (`infra/gitea/**` is, and is a different directory), `platform/pm-agent/**` is
+not (`platform/kyverno/**` is), no `rbac.yaml` and no `*.sops.yaml` is touched, and
+`platform-config/kustomization.yaml` and `CLAUDE.md` are untouched. The gate's own
+`approval-policy` stage is the authority on this and it only evaluates on a
+`pull_request` event, so **read its verdict on the PR** rather than trusting this paragraph.
+
+## What I did NOT verify
+
+- **Nothing here has run against the live Gitea, and nothing here is deployed.** I held no
+  Gitea credential, no kubeconfig and no ServiceAccount token: this container has egress to
+  the in-cluster Gitea and the Anthropic API only, and `kubectl` fails. Every claim below is
+  therefore an operator measurement, not mine.
+- **Every one of the five new Gitea API calls is UNEXERCISED.** `/notifications`,
+  `/pulls/{n}`, `/pulls/{n}/files`, `/pulls/{n}.diff`, `/pulls/{n}/reviews`,
+  `.../reviews/{id}/comments` and `POST /pulls/{n}/reviews` were written to Gitea's published
+  swagger for the 1.24 line. The fixtures prove this program *parses* those shapes; they
+  prove nothing about whether this Gitea *emits* them. The exact read-only curl commands to
+  settle it are in `platform/pm-agent/README.md`, and replacing the fixtures with a real
+  capture is the cheapest way to close the gap.
+- **That `/api/v1/notifications` needs `read:notification` is read from Gitea's documented
+  scope model, not measured.** It is the reason the fallback and the named-remedy log line
+  exist; if the endpoint turns out to work on today's token, the fallback simply never fires.
+- **Whether a notification is actually raised for a mention in an *inline review* comment,
+  and whether `subject.url` is populated for it.** If it is not, discovery via notifications
+  will miss inline mentions and only the `pulls` fallback will find them. Untested; it is the
+  single most likely gap in the cheap query.
+- **Whether `POST /pulls/{n}/reviews` with one comment lands in the *existing* inline
+  thread** or opens a second conversation at the same line. Gitea groups by (path, position)
+  in its UI, which is why this should work, but I have not seen it. The fallback covers
+  outright refusal, not mis-placement.
+- **Whether `position` from a stored review comment is still a valid `new_position` on the
+  current head.** It will not be after a force-push, which is exactly when the inline
+  fallback fires.
+- **The image.** Nothing was built. The Containerfile `verify` stage change (the fixture
+  COPY) has not been run by a container engine — there is none in this container — so the
+  only evidence the selftest passes under the fixture path resolution is the repo-checkout
+  run above, which takes branch 2 of `pr_fixture_path()`. CI's `images` workflow is what
+  exercises branch 3. Related and worth knowing when reading a failure: the selftest's
+  "persona states" assertion fails in *this* container against the baked
+  `/etc/pm-agent/pm-persona.md`, because the image predates this branch. That is an artefact
+  of where the run happened, not a defect — in the built image the two are the same file —
+  but it does mean the image's own selftest invocation (`PM_SELFTEST=1 pm-dispatch`, with no
+  `PM_PERSONA_FILE`) has not been observed passing with this branch's persona.
+- **The two open items from the first version of this branch are closed, and that part is
+  verified offline rather than unverified.** They were "continuation has no end condition"
+  and "another bot commenting on a once-mentioned PR would get a reply". Both are gone by
+  construction: there is no continuation left to terminate, and fixture (q) measures that
+  `renovate` and `gitea-actions` commenting on an answered pull request draw nothing. No
+  ignore-list for automated authors was needed or added.
+
+  **The residual case, stated precisely.** A reply is still reachable by *anyone* who writes
+  the literal handle, including an automation, because the operator's answer (3) is "anyone
+  can talk and have the agent work" and there is no author gate. Two concrete shapes:
+  (1) a bot whose comment template happens to contain `@pm-agent` — e.g. somebody quoting a
+  mention into a Renovate PR description that Renovate then echoes — gets one reply per such
+  comment; (2) **a quoted mention counts as a mention.** Gitea gives this program no way to
+  tell `> @pm-agent what do you think?` pasted into a Markdown quote from a fresh request, so
+  re-quoting an earlier mention in a new comment costs one more decision and one more reply.
+  Both are bounded — one reply per comment id, one decision per pull request per 15 minutes —
+  but neither is prevented. Whether to ignore quoted lines, or particular authors, is a
+  policy call for the operator and not one I should take.
+- **Spend.** `PM_PR_DIFF_MAX_CHARS` defaults to 20000, so a mention costs a decision over a
+  payload meaningfully larger than an issue triage's. No measurement of the real cost exists.
+  Dropping continuation should reduce the *number* of runs substantially — the trigger rate
+  is now how often somebody types the handle rather than how busy a once-mentioned pull
+  request is — but that is reasoning, not a measurement.
+- **R-TEST-06 (spec immutability) and L2/L3 conformance** were not verified by this run —
+  the two gate skips above. And the `approval-policy` stage reported N/A because there was no
+  `pull_request` event; its verdict on the PR is the authoritative one.

+branch: fix/public-dns-wan-a-record
+title: external-dns v0.23 ignored every alpha-prefixed annotation — pin annotationPrefix back
+---
+
+## What changed
+
+`platform/externaldns/helmrelease.yaml`:
+
+- adds `values.annotationPrefix: "external-dns.alpha.kubernetes.io/"`. The chart renders it as
+  `--annotation-prefix=`.
+- tightens the chart range from `<1.24.0` to `>=1.23.0 <1.24.0`, because that flag needs app
+  >= 0.22.
+- adds a comment block explaining why.
+
+**Root cause.** Renovate PR #129 (merged 12:12:00Z) moved the chart from `>=1.21.0 <1.22.0` to
+`<1.24.0`. Helm deployed chart 1.23.0 at 12:13:08Z, which moved the app from v0.21.0 to v0.23.0.
+The upstream v0.22.0 release notes (#6424) say: "The default annotation prefix is now
+`external-dns.kubernetes.io/` with no fallback". Every external-dns annotation in this repo uses
+`external-dns.alpha.kubernetes.io/`. At 12:13:12Z v0.23.0 therefore:
+
+- **ignored the Gateway's `target`.** Every public name flipped from `CNAME
+  wan.home.keithjackson.dev` to `A 192.168.2.20`, an RFC1918 address served in public DNS.
+- **ignored `controller: none`.** The internal names jackett, pihole and semaphore were published.
+  That breaks R-DNS-03.
+- **ignored the L4 Services' `hostname`.** The unifi and crafty-mc A records were deleted.
+
+cloudflare-ddns (#123, v1.18.0) is not involved. It logs only `IPv4-enabled domains:
+wan.home.keithjackson.dev` and has made no changes.
+
+**Why pin the prefix instead of migrating the annotations.** The pin is one value in one file, and
+that file is not on the sensitive-path list. It restores the exact v0.21 reading of `target`,
+`controller` and `hostname` together. A migration would touch `catalog/render.py`, every
+`apps/wave-*` file, the hand-written platform manifests, and the conformance goldens and checks.
+`conformance/**` needs an operator override. And a migration half-applied in either direction
+reproduces this incident.
+
+I rejected `--enable-legacy-annotation-prefix`. Upstream calls it a migration aid that will be
+removed.
+
+**Follow-up.** The L0 guard that the tree's annotation prefix matches this value is a separate PR
+(`feat/l0-externaldns-annotation-prefix`), because it lives in `conformance/**`. A full migration
+to the GA prefix remains open. It must change the annotations and this value in one commit.
+
+## What I verified
+
+- **Live HelmRelease history.** `1.23.0 0.23.0 lastDeployed 2026-11-07T12:13:08Z deployed`, and
+  before that `1.21.1 0.21.0 ... superseded`. The Deployment image is `external-dns:v0.23.0`. The
+  startup config logs `AnnotationPrefix:external-dns.kubernetes.io/
+  EnableLegacyAnnotationPrefix:false`.
+- **external-dns log, 12:13:12Z:**
+  - `action=CREATE ... type=A` and `a-` TXT for gitea, crafty, the apex, headlamp, auth, jackett,
+    nextcloud, keycloak, grafana, seerr, plex, pihole and semaphore.
+  - `action=DELETE ... type=CNAME` and `cname-` TXT for all of those except jackett, pihole and
+    semaphore.
+  - `action=DELETE ... type=A` for unifi and crafty-mc.
+- **Before the upgrade.** Loki covers about 11-05 13:00Z to 12:13Z. The old pod logged no `Changing
+  record` line in that window. Its only error was one Cloudflare 502 on 11-05.
+- **Gateway.** `gateway/shared` still carries `external-dns.alpha.kubernetes.io/target:
+  wan.home.keithjackson.dev`.
+- **Public DNS.** At the authority (betty.ns.cloudflare.com), 1.1.1.1 and 8.8.8.8:
+  - plex, gitea, auth, the apex, jackett, pihole and semaphore answer A `192.168.2.20`.
+  - unifi and crafty-mc have no record.
+  - `wan.` answers A `136.51.115.252`.
+  - There is no AAAA for any of these names.
+  - The `a-plex` and `a-jackett` TXT records read `external-dns/owner=prod`.
+- **Upstream v0.23.0 source.**
+  - `controller/execute.go` calls `annotations.SetAnnotationPrefix(cfg.AnnotationPrefix)`.
+  - `SetAnnotationPrefix` rebuilds `TargetKey`, `ControllerKey` and `HostnameKey`.
+  - `source/gateway.go` still reads `TargetsFromTargetAnnotation(gw.Annotations)`.
+  - Chart 1.23.0 `templates/deployment.yaml` renders `--annotation-prefix={{
+    .Values.annotationPrefix }}`.
+- **Phone.** Pi-hole 192.168.2.23 answers correctly: A `192.168.2.20` with TTL 60, and AAAA
+  NOERROR with no data. The router 192.168.2.1 answers `gitea.` with NOERROR and 0 answers, because
+  it strips RFC1918 results. The workstation uses only `nameserver 192.168.2.23` and has
+  `disable_ipv6 = 1`.
+- **Toolbox gate.** See the PR description.
+
+## What I did NOT verify
+
+- **The fix live.** This depends on Flux applying it. Expected on the first reconcile, with
+  `policy: sync` and owner `prod`, all of these records being prod-owned:
+  - DELETE the A record and create CNAME `wan.` for the ten public names.
+  - DELETE the A and TXT records for jackett, pihole and semaphore.
+  - CREATE A for unifi (.21) and crafty-mc (.22).
+  This is UNVERIFIED until someone reads the external-dns log and checks with `dig
+  @betty.ns.cloudflare.com`. The A-to-CNAME type swap went through cleanly on 2026-10-03, and the
+  reverse went through today, so I expect it to converge. If it does not, see the manual list in
+  the PR.
+- **That the chart's schema accepts `annotationPrefix` under Flux.** I did not render the
+  HelmRelease with helm here. The gate checks YAML and policy, not the chart render.
+- **The phone.** Not investigated, by decision. Likely cause: the phone bypasses Pi-hole on the
+  client side. Candidates are IPv6 RA/RDNSS DNS from the router, Android Private DNS and iCloud
+  Private Relay. Answers it gets that way are rebind-stripped, or point to the WAN IP, which needs
+  hairpin NAT. Hairpin looked absent on 2026-10-03 (a self-signed cert on WAN:443). This is
+  router- or client-side, not in-repo.
+- The AAAA records the operator saw on 8.8.8.8. I did not reproduce them.
+- The cilium (#104) and pihole (#109) bumps were not examined beyond Pi-hole answering correctly.

+clients Google's IPv6 DNS, so split DNS keeps breaking. This is **Phase 1: the connector only.**
+external-dns, the Gateway annotations, Pi-hole and CoreDNS are untouched. A later change, by a
+different agent, moves DNS.
+
+**Operator decisions (2026-11-08), recorded here as the source for the guard:**
+
+1. Public hostnames stay `*.home.keithjackson.dev` and the apex `home.keithjackson.dev`. The
+   operator enables Cloudflare ACM (ordered edge cert or Total TLS) for edge certificates.
+2. **Plex stays OFF the tunnel.** No plex hostname goes through cloudflared (`plex`, `plex-vip` → 404).
+3. **jackett, pihole and semaphore stay LAN/VPN-only**, never via the tunnel. The same goes for the
+   non-HTTP L4 VIPs **unifi** and **crafty-mc**. After the PM's read-only audit, the other three
+   catalog `exposure: internal` apps, **qbittorrent, radarr and sonarr**, are on the same list. All
+   six carry the external-dns `controller: none` route annotation live.
+4. **The Kubernetes API stays local-only.** It must never be reachable through the tunnel.
+5. Pi-hole keeps serving the LAN. Split DNS gets trimmed later, by another agent.
+6. **Headlamp is LAN/VPN-only** (operator decision, relayed by the PM later the same day). It is
+   permanently in the 404 list and excluded from the egress backends. Its catalog/route exposure is
+   deliberately **not** changed here; the Phase 2 DNS-flip PR does that.
+
+**Files:**
+
+- `platform/cloudflared/` (new):
+  - `config.yaml` is the locally-managed tunnel config, projected through a content-hashed
+    `configMapGenerator`, so edits roll the pods. It has explicit `http_status:404` rules for
+    plex, plex-vip, jackett, pihole, pihole-dns, semaphore, qbittorrent, radarr, sonarr, headlamp,
+    unifi and crafty-mc. Then the apex and `*.${BASE_DOMAIN}` go to
+    `https://cilium-gateway-shared.gateway.svc.cluster.local:443` with `matchSNItoHost: true`. Last
+    comes a catch-all 404. The tunnel UUID is a **literal** in this file (`REPLACE-ME-TUNNEL-UUID`
+    until enrolment), not a cluster-var, so the Phase 2 PR can match it without touching `clusters/**`.
+  - `cloudflared-credentials.sops.yaml` is SOPS-encrypted and holds `REPLACE-ME` placeholders, with
+    a `.example` hand-off sibling. I encrypted the placeholder (not a credential) in the toolbox
+    with the root `.sops.yaml` recipient.
+  - `deployment.yaml` runs 2 replicas with a hard `topologySpreadConstraints` across nodes. The image
+    is `cloudflare/cloudflared:2026.10.7@sha256:4955524a…` (tag + digest, Renovate `kubernetes`
+    manager). It runs as non-root 65532, with a read-only root fs, all capabilities dropped and no
+    SA token. Requests are 10m/64Mi and limits 500m/256Mi. Readiness uses `/ready`. Liveness uses
+    `/healthcheck`, so an edge outage cannot restart-loop the pods. The pods are labelled
+    `egress-class: internet`. A PDB sets `minAvailable: 1`.
+  - `networkpolicy.yaml`:
+    - A namespace `default-deny` with DNS only. It has a **single owner**: the namespace is not
+      `app-namespace=true`, so Kyverno's generate rule never writes it.
+    - A Prometheus scrape allow on :2000.
+    - The egress CNP allows world tcp/udp 7844 and tcp 443, plus the `ingress` entity on tcp 443.
+      It also allows **Gateway backends by `io.cilium.k8s.namespace.labels.gateway-access=shared`,
+      minus the LAN-only namespaces.**
+  - `servicemonitor.yaml` (headless metrics Service + ServiceMonitor) and `alerts.yaml` (`CloudflaredTunnelDown`, `CloudflaredReplicasDegraded`)
+    ship with `alerts.promtool-test.yaml`, and `README.md` documents the component.
+- `clusters/base/cloudflared.yaml` (new) is its own Flux Kustomization: `dependsOn: platform-config`,
+  **`wait: false`**, prune, and postBuild `cluster-vars`. It is listed in `clusters/base/kustomization.yaml`.
+- `clusters/{dev,prod}/kustomization.yaml` each gain a SOPS `decryption` patch for `cloudflared`.
+- `conformance/tests/l0-static/cloudflared-ingress-rules/` (new, whole-repo scope) asserts several
+  things:
+  - Every rule targets either 404 or exactly the Gateway Service. The Service name is derived from
+    `platform/gateway/gateway.yaml`, and API markers are named explicitly.
+  - The excluded hosts 404 before the first Gateway rule, the Gateway rules use `matchSNItoHost`,
+    there is no `noTLSVerify`, and a catch-all closes the list.
+  - The CNP has no kube-apiserver, host, remote-node, cluster or `all` entity, no CIDR, and the full
+    NotIn list. The pods carry egress-class internet and have no SA token.
+  - The Flux tier is isolated: wait:false, not in `platform/kustomization.yaml`, nothing
+    `dependsOn: cloudflared`, and both overlays decrypt it.
+  - **Mutation self-test:** an added API rule, plex moved below the wildcard, and a dropped
+    catch-all must each be flagged.
+- `conformance/tests/l0-static/alert-metrics-have-scrape-targets/check.sh` gains an additive
+  `cloudflared_` scrape owner, with a networkpolicy companion, in the same shape as the kured entry.
+- `runbooks/cloudflare-tunnel.md` (new) is registered in `runbooks/kustomization.yaml` and the
+  README index.
+
+**Design choices:**
+
+- **Isolation (the merge-before-credentials question).** The PR is safe to merge with placeholders.
+  The Deployment CrashLoops, but in its own `wait:false` Kustomization that nothing depends on. Its
+  Ready condition tracks the apply, not pod health, so neither `platform`, `platform-config` nor any
+  apps wave can stall. There is no Certificate or HelmRelease in the path for health checks to hang
+  on. Health is reported by the two alerts instead. `CloudflaredTunnelDown` **will fire from merge
+  until enrolment**. That is honest, and it is `warning` because nothing routes through the tunnel
+  yet. Raise it to critical in the DNS-flip change.
+- **Egress to backends, not `{}`.** Under Cilium 1.20 (CVE-2025-30162), the Gateway's Envoy
+  re-checks the source pod's egress against the resolved backend. An egress rule that names only
+  the Gateway would therefore make every tunnelled request `403 Access denied`
+  (decisions/2026-10-30-gitea-admit-buildkit.md; catalog/render.py, `r_internet_egress`). The
+  gitea-actions `- {}` pattern would also work, but it admits kube-apiserver and host, which
+  decision 4 rules out. The namespace-label selector names every Gateway backend and nothing else.
+  **Backends need no ingress change.** Envoy reaches them as `reserved:ingress`, and the 2026-10-30
+  measurement showed the identity check sits on the source's egress: gitea-actions is in none of
+  Gitea's ingress allows and still reaches it. So no app's `inClusterClients` was touched.
+- **The alerts cannot self-silence.** Both expressions use `or on() vector(0)`, so absent series
+  (a broken scrape, zero pods, KSM gone) fire. The promtool tests pin the absent case and the
+  working-then-stale re-fire case.
+
+## What I verified
+
+- **The Gateway Service, measured live (read-only, `k3s-prod`, 2026-11-08).** It is
+  `gateway/cilium-gateway-shared`: type LoadBalancer, ClusterIP `10.43.225.79`, EXTERNAL-IP
+  `192.168.2.20`, ports 80/443, no selector, labelled `gateway.networking.k8s.io/gateway-name=shared`.
+  It belongs to Gateway `gateway/shared` (class `cilium`).
+- **The namespace selector, measured live.** Cilium identities carry the label
+  `k8s:io.cilium.k8s.namespace.labels.gateway-access` (read from a gitea identity). Every namespace
+  with an HTTPRoute (crafty, gitea, headlamp, homepage, jackett, keycloak, monitoring, nextcloud,
+  oauth2-proxy, pihole, plex, qbittorrent, radarr, runbooks, seerr, semaphore, sonarr) is
+  `gateway-access=shared`.
+- **Nothing exists yet.** Namespace `cloudflared` does not exist on prod. **cloudflared is not in
+  the pinned toolbox**, so the runbook runs the pinned image under podman instead.
+- The image tag and digest came from Docker Hub's API: `2026.10.7` = `latest` =
+  `sha256:4955524a…c9b9c5ba`, published 2026-10-30.
+- The credentials Secret is encrypted: `stringData.credentials.json` is `ENC[…]`, with the age
+  recipient from the root `.sops.yaml`.
+- The new L0 check passes on the host (47 assertions, mutation self-test included). The toolbox
+  gate result is reported in the PR description. I ran it after committing.
+
+## What I did NOT verify
+
+- **UNVERIFIED: nothing ran in a cluster.** No pod has started, and no tunnel exists. I have not
+  observed placeholder CrashLoop behaviour itself. I expect cloudflared to treat
+  `REPLACE-ME-TUNNEL-UUID` as a tunnel name, find no origin cert, and exit, but whatever it does,
+  the pods are not Ready and the tier is non-gating.
+- **UNVERIFIED: the CVE-2025-30162 path for cloudflared specifically.** The selector form was
+  checked against live identity labels, but no tunnelled request has been made. The runbook's
+  step 6 `kubectl debug` probe exists to prove "real backend, no 403" from the pod's own identity.
+- **UNVERIFIED: whether the `ingress` entity rule's `toPorts: 443` restriction holds at Envoy.**
+  buildkit's working rule has no port restriction. If the canary shows drops, removing the port
+  restriction there is the first thing to try.
+- The metric name `cloudflared_tunnel_ha_connections` and the `/ready` / `/healthcheck` endpoints
+  come from my knowledge of cloudflared, **not measured** against 2026.10.7.
+- The Cloudflare edge egress is `world` + ports, not Cloudflare CIDRs. I did not narrow it blind.
+- Egress `world:443` "for the API" follows the brief. I have not confirmed that a credentials-file
+  tunnel needs it at all.
+- The Cloudflare-side settings (ACM, Total TLS / ordered cert, Bot Fight Mode, BIC/WAF, WebSockets)
+  are documented for the operator but not inspected. I have no Cloudflare access.
+- The headlamp, qbittorrent, radarr and sonarr catalog exposures are deliberately unchanged
+  (Phase 2).

+title: cloudflared CrashLoop — credentials Secret unreadable by uid 65532; add fsGroup, pin it in L0
+---
+
+## What changed
+
+- **`platform/cloudflared/deployment.yaml`**: pod `securityContext.fsGroup: 65532`. Root cause of
+  the CrashLoop that followed #152/#153: the pod runs as `65532:65532` with no `fsGroup`, and the
+  Secret volume is `defaultMode: 0440`. The kubelet therefore laid `credentials.json` down as
+  `root:root 0440`, which uid 65532 (not owner, not in gid 0) cannot read. cloudflared logged
+  `couldn't read tunnel credentials ... permission denied`, then fell back to origin-cert lookup
+  and ended on the misleading `error parsing tunnel ID: Error locating origin cert`. With
+  `fsGroup` the files are group-owned by 65532, readable by the container and no other uid; the
+  mode stays 0440 (not loosened to 0444). Same fix as `platform/keycloak/client-secret-reconciler.yaml`.
+  Still non-root, `runAsNonRoot: true`, unchanged otherwise.
+- **`conformance/tests/l0-static/cloudflared-ingress-rules/check.sh`**: new assertion (7). For each
+  Secret volume a container mounts, it models kubelet ownership (uid 0, gid = fsGroup or 0, item
+  mode / defaultMode / API default 0644) against the container's effective runAsUser and its groups
+  (runAsGroup + fsGroup + supplementalGroups) and fails if the file is unreadable. An unset
+  runAsUser fails (image default is not knowable offline). Conservative: it does not credit the
+  kubelet OR-ing group-read into fsGroup volumes. Mutation self-test: fsGroup removed, mode 0400,
+  runAsUser unset must each be flagged. Chainsaw step description updated to match.
+- **`runbooks/cloudflare-tunnel.md`**: new first "likely cause" (permission denied on
+  credentials.json → the origin-cert error is a red herring) plus a "read the first error line"
+  note; causes renumbered. New section **Rotating the tunnel credential**: create a new tunnel,
+  swap the UUID and the encrypted credentials, merge, verify (new tunnel has two connectors, old
+  has none), then `cloudflared tunnel cleanup`/`delete <old>`.
+- NOT touched, on purpose: `tunnel:` in `config.yaml` and `cloudflared-credentials.sops.yaml`. The
+  operator is rotating the credential (it was exposed in a transcript) in a separate PR.
+
+## What I verified
+
+- Live (k3s-prod, read-only, 2026-11-08 ~21:38Z): Deployment pod securityContext is
+  `{"runAsGroup":65532,"runAsNonRoot":true,"runAsUser":65532,"seccompProfile":...}`, no
+  `fsGroup`; creds volume `defaultMode: 288` (= 0440). All three pods CrashLoopBackOff (38
+  restarts). Secret `cloudflared-credentials` has the one key `credentials.json` (key names only).
+- Pinned image `cloudflare/cloudflared@sha256:4955524a...` config (`skopeo inspect --config`):
+  `User: 65532:65532`, `Entrypoint: [cloudflared]`, `Cmd: [version]`.
+- The new assertion FAILS (rc 1) on the pre-fix deployment.yaml with
+  `container cloudflared (uid 65532, groups [65532]) cannot read Secret volume creds ... files are
+  0:0 mode 0440`, and PASSES (51 assertions) with the fix. All three mutants are flagged.
+- Kyverno admission policies under `platform/kyverno/admission/` that mention securityContext
+  fields are scoped to the conformance-trigger and pm-agent Jobs only; none constrains fsGroup here.
+- Toolbox gate: see the PR description for the rc and skipped stages.
+
+## What I did NOT verify
+
+- **That the pods actually become Ready after merge.** Not deployed by me; Flux applies it. The
+  file mode inside the running container was not observed (pods crash before an exec is possible,
+  and exec would be an operator action anyway). The readability claim rests on the kubelet's
+  documented fsGroup behaviour and the identical, working keycloak reconciler.
+- Whether the CURRENT credential is otherwise valid (UUID/TunnelID match, tunnel exists). Moot:
+  the operator is rotating it.
+- The rotation runbook section has not been executed; `cloudflared tunnel cleanup` / `delete`
+  syntax is from the CLI's documented commands, not run here.
+- The deployment comment says the image ENTRYPOINT is `cloudflared --no-autoupdate`; the pinned
+  image's ENTRYPOINT is plain `cloudflared`. Left unchanged (out of scope); flagged for follow-up.

+---
+
+## What changed
+
+One atomic change, so the conformance guard lands with the DNS flip.
+
+- `platform/gateway/gateway.yaml`: the shared Gateway's `external-dns.alpha.kubernetes.io/target`
+  is now the literal `fc81938b-5855-47f1-8a27-6286f56dda93.cfargotunnel.com` (was
+  `wan.${BASE_DOMAIN}`). Comment block rewritten.
+- `platform/externaldns/helmrelease.yaml`: `extraArgs: [--cloudflare-proxied]` (global, because
+  v0.23.0 reads per-object `cloudflare-proxied` from the route/Service, never the Gateway). The
+  public-target comment block rewritten, including the prefix-regression risk.
+- `apps/vms/unifi/50-service-l4.yaml`, `platform/crafty/service-l4.yaml`:
+  `external-dns.alpha.kubernetes.io/cloudflare-proxied: "false"` (L4 A records stay DNS-only). They
+  are the only `service`-source publishers in the tree and live (measured).
+- Plex web UI LAN/VPN-only: `catalog/plex.yaml` `exposure: public` → `internal`; `apps/wave-0/plex.yaml`
+  re-rendered with the canonical command into a scratch dir and ONLY plex.yaml copied back. The
+  render diff is exactly +2 lines (`annotations: external-dns.alpha.kubernetes.io/controller: none`
+  on HTTPRoute plex-32400). No other golden moved, and nothing was onboarded (vm-demo/keycloak files
+  were not touched). ADVERTISE_IP, the L4 VIP .24 and `plex-remote.yaml` are untouched.
+- Headlamp LAN/VPN-only: `controller: none` on the hand-authored `platform/headlamp/httproute.yaml`.
+- `conformance/tests/l0-static/internal-services-publish-no-public-dns/check.sh`: header and
+  register prose updated; new assertion (9):
+  (9a) Gateway target == `<tunnel: from platform/cloudflared/config.yaml>.cfargotunnel.com`, and
+  `--cloudflare-proxied` is set; (9b) every `service`-source publisher has `cloudflare-proxied:
+  "false"` and no HTTPRoute opts out of proxying; (9c) no undisowned route names a hostname the
+  tunnel 404s, the only `service` publishers of a 404'd name are the declared L4 set
+  {unifi, crafty-mc}, and every disowned route's hostname IS 404'd by the tunnel (lists kept
+  consistent both ways); (9d) plex and headlamp pinned disowned. Its `chainsaw-test.yaml` gap prose
+  updated.
+- `conformance/tests/l2-behavioral/dns-exposure/chainsaw-test.yaml`: fixture Service gets
+  `cloudflare-proxied: "false"`, else the global flag proxies it and the exact-IP poll fails.
+- Docs: `platform/externaldns/ddns.yaml` header (wan. is WireGuard-only), `platform/externaldns/README.md`,
+  `platform/gateway/README.md`, `runbooks/plex-remote-access.md`, `runbooks/cloudflare-tunnel.md`
+  (Phase 2 done; operator step to close WAN tcp/80+443 and keep udp/51820 + tcp/32400; rotation
+  now also swaps the Gateway UUID; rollback path).
+
+## What I verified
+
+- external-dns v0.23.0 source, read at the tag: `source/gateway.go` takes target overrides from
+  `gw.Annotations` and provider-specific (incl. `cloudflare-proxied`) from the ROUTE's annotations;
+  `annotations.SetAnnotationPrefix` re-derives `CloudflarePrefix`, so the alpha-prefixed key is the
+  one read here; `provider/cloudflare` `shouldBeProxied` starts from `--cloudflare-proxied` and a
+  parsed `"false"` annotation overrides it.
+- (8b) only forbids `annotation-prefix` / `enable-legacy-annotation-prefix` in extraArgs; a mutation
+  confirmed `--cloudflare-proxied` passes and `--annotation-prefix=x/` fails.
+- The L0 check passes (116 assertions) and each new assertion FAILS on its mutation: Gateway target
+  back to wan (9a), flag removed (9a), unifi proxied "true" (9b), headlamp undisowned (9c,9d), plex
+  golden undisowned (9c,9d,(1)), jackett removed from the tunnel's 404 list (9c).
+  `cloudflared-ingress-rules` still passes; `render.py --selftest` PASS.
+- Live, read-only (kubectl k3s-prod, ~23:55Z): 17 HTTPRoutes; the six internal apps carry
+  `controller: none`; plex and headlamp do not (yet); the only Services with an external-dns
+  hostname are crafty/crafty-l4-tcp and unifi/unifi-l4-tcp; Gateway target is currently
+  `wan.home.keithjackson.dev`.
+- Toolbox gate result: see the PR description (rc and skipped stages quoted there).
+
+## What I did NOT verify
+
+- Anything after merge: that external-dns actually UPDATEs the eight public names to proxied CNAMEs
+  to the tunnel, DELETEs plex + headlamp and their TXT, and leaves unifi/crafty-mc/wan untouched.
+  Expected effect is listed in the PR; the PM must read external-dns logs and `dig @1.1.1.1`.
+- A rendered HelmRelease: I read the chart 1.23.0 `templates/deployment.yaml` (a list `extraArgs`
+  is emitted item-by-item via `tpl . $ | quote`), but did not `helm template` it.
+- kubectl OIDC from nodes: nodes resolve publicly, so `keycloak.` discovery/JWKS now goes through
+  Cloudflare + the tunnel. No `oidc-ca-file` is set (system roots), so the edge cert should validate,
+  but Cloudflare bot/WAF settings on that path are untested.
+- RISK: if the annotation prefix stops being honoured at runtime again (11-07 incident class),
+  `target` is ignored and every name becomes a PROXIED A record at 192.168.2.20, while internal
+  names publish. Assertion (8) only keeps the tree and `values.annotationPrefix` consistent; it
+  cannot catch a controller that ignores the flag. No runtime alert exists for it.
+- The router WAN 80/443 close is an operator step, not done. The Pi-hole wildcard trim is a later PR.
+- Follow-up: spec requirement IDs for this (proposed R-DNS-04/05, R-SEC-04) once the spec ADR merges;
+  `platform/pm-agent/README.md` and a comment in `catalog/pihole.yaml` still describe the wan. CNAME.

+title: The merge gate runs inside the CI-built toolbox image, pinned by digest — no per-run tool install
+---
+
+## What changed
+
+`.gitea/workflows/gate.yml`, job `gate` (job name, the gate step, its env and its
+`|| [ "$?" -eq 3 ]` tolerance are unchanged, so the required context `gate / gate (pull_request)`
+is unchanged):
+
+- **`container:`** `gitea.home.keithjackson.dev/home-network/toolbox@sha256:83a3501e…ef81` — the
+  image `images.yaml` published from `dd94101` (run 789; it is today's `main` and `sha-dd941016478c`
+  tag). The same image `infra/devcontainer/dev.sh` runs, so local and CI gate on the identical
+  toolchain. A `# renovate-digest: image=… tag=main` marker sits on the line above, the repo's
+  existing convention; `infra/gitea/registry-retention.sh` reads the same marker, so this digest
+  is protected from pruning.
+- **`actions/checkout` replaced by a plain-git step.** The toolbox has no Node (measured:
+  `command -v node` → missing), and `actions/checkout` is a Node action. Chosen over adding Node to
+  the toolbox because that would need two sequential PRs (Containerfile, then a publish, then the
+  pin) and would put a JS runtime into the operator toolbox only to run one action. The step
+  reproduces what checkout@v7 `fetch-depth: 0` actually ran here (read from runs 490 and 495):
+  every branch to `refs/remotes/origin/*`, tags, plus the event SHA; detached for a PR,
+  `-B <branch>` for a push; asserts `HEAD == github.sha`. The job token goes to that one fetch via
+  `GIT_CONFIG_*` env and is **not** persisted in `.git/config` (nothing later needs network git).
+  It sets **`umask 0022`** first: the PR's first CI run (run 500) failed L0
+  `prod-baremetal-not-dev-surface` because act runs steps with umask 0000, every checked-out
+  directory was world-writable, and Ansible (present in the toolbox, absent from the catthehacker
+  image) then ignored `infra/ansible/ansible.cfg`. Reproduced locally in the pinned image: clone
+  under umask 0000 → that check fails with the same message; under 0022 → `check OK`. Side
+  effect worth knowing: the Ansible-driven parts of that check now actually execute in CI.
+- **"Install pinned CI toolchain" step removed**, replaced by **"Toolchain is the one
+  ci/versions.env pins"**: every `*_VERSION` in `ci/versions.env` must equal the image's
+  `/etc/dev-toolchain-versions`, else `::error::DRIFT` and the job fails. Without this, dropping
+  the installer would have made `ci/versions.env` an unenforced claim for everything except
+  promtool (which `alert-rules-unit-tested` already asserts).
+- Header comments rewritten for the new job image (pull auth, cold-pull size, no-Node, why
+  `install-tools.sh` stays).
+
+`renovate.json5`: the `renovate-digest` custom manager now also scans `.gitea/workflows/gate.yml`;
+the `github-actions` manager is disabled for this repo's own images (same reason the `kubernetes`
+manager already was: it would see a digest-only image and look up `latest`).
+
+Comment/message wording only: `ci/gate.sh` (header + the strict-skip error text), `ci/lib.sh`,
+`ci/README.md`, `.gitea/workflows/README.md` — they said the CI toolchain comes from
+`install-tools.sh`.
+
+`.gitea/workflows/scripts/install-tools.sh` is **kept**: `merge-gate.yaml` (dormant blueprint)
+calls it, and `conformance/tests/l0-static/alert-rules-unit-tested/check.sh` asserts its promtool
+wiring (not touched — another agent owns `conformance/`).
+
+**Consequence to know:** every toolbox digest bump is now a Renovate PR touching `.gitea/**`,
+i.e. a sensitive path needing an operator `/approve-override`. That is arguably correct (a new
+toolchain changes what green means — and `ci/versions.env` was already sensitive), but it is a
+new recurring operator touch.
+
+## What I verified
+
+- Registry pull auth: the Home-Network org is `public`; anonymous `/v2/token` → manifest `200`,
+  `docker-content-digest: sha256:83a3501e…ef81` for both `main` and `sha-dd941016478c`. So no
+  `container: credentials:` is needed. (The Actions token could not have been used anyway — no
+  package scope, per images.yaml's header.)
+- Image: 466,912,274 bytes compressed across 6 layers (manifest sum), 1,541,728,125 bytes
+  unpacked (`podman image inspect`). Local cold pull 10.4s on the workstation.

+  chainsaw 0.2.12, yamllint 1.35.1, kubectl 1.36.4, yq 4.44.6, promtool 3.14.0, check-jsonschema
+  0.29.4) — both via `/etc/dev-toolchain-versions` and by running each binary's `--version`.
+  `sleep`, `tail`, `git` 2.56.0, `bash`, `python3`, `jq`, `curl` present (act's entrypoint is
+  `/bin/sleep 10800`).
+- The new checkout script, run in the pinned image against the public repo (auth header disabled

+title: "Keycloak 26.8.2 operator CrashLoop: install its two new CRDs, raise its memory"
+---
+
+## 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.

+title: One owner for the keycloak ServiceMonitor — disable the 26.8 operator's (409 loop stalled platform-config)
+---
+
+## 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`.

+title: L0 offline checks, mutation suites and yamllint run in bounded parallel pools (gate 184s -> 32s locally)
+---
+
+## What changed
+
+The gate's wall time was dominated by serial loops over independent subprocesses. Three of
+them now run in bounded pools; none of them changes a verdict, an exit code, or the order of
+anything printed.
+
+- `conformance/lib/run_l1_offline.py` — the per-check loop (L0 and L1 offline checks) runs in
+  a `ThreadPoolExecutor` of `bash <check>` children. `--jobs N` / env `CONF_OFFLINE_JOBS`,
+  default `min(8, usable CPUs)` (`sched_getaffinity`, so a cgroup cpuset is respected);
+  `--jobs 1` is the old serial runner. Results are consumed in SUBMISSION order, so `cases`,
+  the JUnit, the step summary and the 0/1/3 aggregation are built from exactly the same
+  ordered list as before. Additive output only: one `[offline] running N check(s), jobs=…`
+  line, and a trailing `[N.Ns]` wall time on each per-check status line. Children get
+  `stdin=/dev/null` (parallel children must not share the runner's stdin).
+- `conformance/tests/l0-static/keycloak-{passkey,client-secret}-reconciler/mutations.py` —
+  pass 1 (serial) checks every anchor and builds each mutated source, exactly as before;
+  pass 2 runs the `--selftest` children in a pool (env `MUTATION_JOBS`, default
+  `min(8, CPUs)`, `1` = serial). Verdicts are consumed in `MUTATIONS` order. A timeout
+  (`TimeoutExpired`) still propagates and fails the check; queued mutations are cancelled.
+  An invalid `MUTATION_JOBS` exits 2 (fails the check, never skips it).
+- **Nested-pool budget.** When the outer runner is parallel it exports
+  `MUTATION_JOBS = max(2, min(8, (cpus - jobs + 2) // 2))` unless the caller already set
+  one. Reason: only those two checks fan out; the other `jobs-2` workers are single
+  processes, so the two suites split the CPUs those leave free. Peak processes ≈
+  `(jobs-2) + 2*inner` ≤ cpus whenever cpus ≥ jobs+2 (24 CPUs: 6 + 16 = 22), and ~1.25–1.5×
+  cpus on a small runner (4 CPUs: 2 + 4 = 6). The floor of 2 is deliberate: a 1-wide inner
+  pool would make the 40-mutation passkey suite (~85s serial) the critical path of the stage.
+- `ci/lint.sh` — yamllint runs over `LINT_JOBS` (default `min(8, nproc)`) CONTIGUOUS slices
+  of the sorted file list concurrently; each slice's output is buffered to its own file and
+  printed in slice order, so the text is the same as one serial call and a `file` header is
+  never separated from its `line:col` findings. Stage rc = the highest slice rc; a slice that
+  leaves no rc file counts as 1. Invalid `LINT_JOBS` exits 2.
+
+### Parallel-safety audit (all 25 `l0-static/*/check.sh`, 3 `l1-rendering/*/render-check.sh`)
+
+Grepped every check for fixed `/tmp` paths, `_artifacts`/`ARTIFACTS`/`COVERAGE_OUT`,
+`write_text`/`open(…,"w")`, `mktemp`/`mkdtemp`/`TemporaryDirectory`, sockets/ports, `git`
+writes and `run.sh` invocations, and read what each writer writes to:
+
+- **Scratch state: all private.** Every writer uses its own `mktemp -d` / `mkdtemp` /
+  `TemporaryDirectory` (placeholder-guard-coupling, spec-immutability-enforced,
+  whole-repo-invariants-wired, auditability-proofs-producible, alert-rules-unit-tested and its
+  `platform/monitoring/tests/run.sh`, internal-services-publish-no-public-dns,
+  oauth2-proxy-{api-routes-per-app,cookie-names-distinct}, both keycloak reconcilers, the three
+  L1 render checks). No fixed `/tmp` path anywhere.
+- **Git writes:** only spec-immutability-enforced, and only `git init/add/commit` inside its
+  own `mktemp` repo. Everything else is `git ls-files`/`ls-tree`/`log`/`rev-parse` (read-only).
+- **Ports:** the reconciler selftests bind `127.0.0.1:0` (kernel-assigned); the passkey
+  selftest also dials `127.0.0.1:1` as a deliberate refused connection. No fixed listener.
+- **Ansible** (dev-nodes-provisioned-as-code): `--syntax-check`/`--list-hosts` only,
+  `retry_files_enabled = False`; its local tmp is per-process.
+- **The one shared writer:** auditability-proofs-producible runs
+  `./run.sh --coverage-only --requirements …`, which REWRITES
+  `conformance/_artifacts/coverage/coverage.{json,md}` (it inherits `CONF_ARTIFACTS`). That was
+  already true serially. No other offline check reads or writes that directory (the only
+  reader is `tests/meta/harness-selfcheck`, not an offline check), and the outer runner
+  writes coverage BEFORE and the JUnit AFTER the pool, so the final state is the same as
+  serial. Not serialised; left as is and recorded here. `lib/status.py` (run by that check)
+  reads `_artifacts/report.junit.xml` as an advisory — written only after the pool, unchanged.
+- whole-repo-invariants-wired calls `run.sh --print-selection` (writes nothing) and the
+  runner itself against synthetic dirs in its own `mktemp`.
+
+Result: no check needed fixing or serialising. A new check that needs shared state must say
+so; the runner's docstring now states that contract.
+
+## What I verified
+
+All in the pinned toolbox (`dev.sh run`, `DEV_KUBECONFIG=/dev/null`, ENGINE shim adding a ro
+mount of the main checkout's `.git`; spec repo resolved as a sibling, spec-immutability
+`pass`), host 24 CPUs, every `dev.sh` call under `flock`.
+
+- **Gate, before** (origin/main `1a33814`, detached scratch worktree + spec mount):
+  `GATE_RC=3`, in-container wall **183.9s**; `l0` stage **168.3s**, `lint` **7.8s**.
+  "Stages that did not run: gitea-settings" (plus the expected on-base
+  touched-set-not-determinable note, since main has no branch commits).
+- **Gate, after** (this branch, commit `a775082`): `GATE_RC=3`, in-container wall **32.1s**;
+  `l0` **21.1s**, `lint` **2.4s**, `l1` 2.3s. "Stages that did not run: gitea-settings" — the
+  only not-run stage. **rc 3, not green.** Caveat: the branch run selected 23 L0 checks (the
+  touched-requirement scoping dropped dev-nodes-provisioned-as-code and
+  placeholder-guard-coupling), the main run 25.
+- **Same-tree L0 comparison** (all 25 l0 dirs, same tree, same container):
+  `CONF_OFFLINE_JOBS=1 MUTATION_JOBS=1` **164.0s / 165.3s** vs default (jobs=8,
+  MUTATION_JOBS=8) **19.2s / 18.7s**. JUnit `cmp`-identical, step summary `cmp`-identical,
+  stderr identical except the timing suffixes and the JUnit path in the last line.
+- **Mutation suites, host:** passkey 83.2s → 10.5s (`MUTATION_JOBS=8`), client-secret
+  11.2s → 2.0s; output of `MUTATION_JOBS=1` and `=8` byte-identical to the pre-change script's,
+  rc 0 all round.
+- **Falsification (not committed):** in a scratch worktree at `a775082`, made the passkey
+  mutation "the protected-subtree screen is never called" a no-op (replacement == anchor).
+  Host: `MUTATION_JOBS=1` and `=8` both rc 1, output byte-identical (with a second, broken
+  anchor also injected: both reported). Toolbox: runner rc 1 both serial and parallel,
+  `L0 FAIL keycloak-passkey-reconciler … 1 of 40 mutation(s) not proven … SURVIVED`; full
+  gate **rc 1**, `stage l0: FAIL`, `MERGE GATE: BLOCKED`. Reverted; scratch worktree removed.
+- **lint.sh, host scratch repo** (31 YAML files, two broken): `LINT_JOBS=1/4/8` all rc 1,
+  stdout identical, findings named `y/f07.yaml` / `2:1 … key-duplicates` etc.; clean tree rc 0;
+  `LINT_JOBS=x` rc 2.
+
+## What I did NOT verify
+
+- **CI timings at the time of writing.** The PR's CI run is measured after push and reported
+  on the PR / handoff message, not here. The CI runner's CPU count is UNVERIFIED — the new
+  `[offline] running … jobs=… cpus=…` line in the CI log is what will show it. On a small
+  runner the speedup will be smaller than locally.
+- **approval-policy** will be red on CI: `ci/**` and `conformance/**` are sensitive paths and
+  need the operator's review. I did not and must not override it.
+- Flakiness under load: the selftests have no wall-clock assertions I found, and 4 toolbox
+  runs + several host runs were all stable, but that is a handful of runs, not a soak.
+- The coverage files under `conformance/_artifacts/coverage/` end in the same state as before
+  only because a single check rewrites them; I did not change that pre-existing quirk.
+- L2/L3 conformance: not run (no cluster in CI, as before).
