`claude --print --output-format json` reports its own failures (API error, usage limit,
error_max_turns) as the result envelope on stdout and leaves stderr empty, so ask_pm()'s
stderr-only message logged "claude exited 1: " with nothing after it, twice on 2026-10-31.
describe_cli_failure() now logs the envelope's diagnostic fields plus stdout/stderr tails,
redacted (sk-ant-, Bearer/token, URL userinfo). PM_DECISION_MAX_TURNS (default 1, unchanged)
makes the max-turns remedy a ConfigMap change if the envelope turns out to say error_max_turns.

The run-383 worker image (df36d9b, pinned in #96) bakes imagePullSecrets: pm-agent-registry,
which admission requires, and the dispatcher's dry-run triage of #97 was read and approved.
PM_REQUIRE_LABEL=agent and the worker caps are unchanged. The dry-run status text in the
configmap comments, the README and the plan's follow-up 3 is updated to match.
Pre-flight (read-only, k3s-prod): pm-agent-job-shape Ready+Enforce; SA/Role/RoleBinding
present and can-i create jobs = yes; pm-agent-registry and pm-agent-credentials exist; both
egress CNPs Valid.

Rebased #61 onto the CI image pipeline (#81). This commit makes the remaining in-git
blockers to going live go away:
- deployment.yaml and PM_WORKER_IMAGE pin images run 340's digest (sha256:c4eba5b3...,
tag sha-523cd9118f95 = main), read from the registry. Renovate markers unchanged.
- PM_DRY_RUN=true and PM_REQUIRE_LABEL=agent for the first run. Dry run is required, not
just cautious: the run-340 image's baked worker template predates imagePullSecrets, so
admission would deny its Jobs until CI re-publishes after this merge and Renovate bumps.
- Token scopes: Gitea 1.24.3 scopes GET /api/v1/user (the dispatcher's first call) under
read:user. The documented list was missing it. Now read:user, write:repository,
write:issue, read:package everywhere.
- Org-package read documented as a team (Packages=Read, no repos), not just a scope.
- sops is toolbox-only; the .examples say so and give the in-place edit.
- runbook: key-name check no longer emits Secret values before the pipe.

The registry had two blockers. #59 fixed the first (nodes resolved the hostname to the
non-hairpinned WAN and failed TLS against the router's CN=%D cert). This is the second:
the pull is unauthenticated, and this registry refuses unauthenticated clients outright —
measured 2026-10-05, its anonymous token carries access: null and every path 401s.
pm-agent-registry is a dockerconfigjson Secret (SOPS, placeholders) referenced by
imagePullSecrets on the dispatcher Deployment and on the committed worker Job template. It
holds 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. Same one-value-in-two-files pattern as the Keycloak client
secret, documented in both .example files. The operator's part is the value plus one new
scope: read:package.
ADMISSION GAINED A SEVENTH RULE. imagePullSecrets is a pod-spec field 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; rule 7 forbids any other and any second one. Both halves are needed: a
foreach over an absent list yields no result.
The leverage is small and the policy says so: the image is digest-pinned, so a different
pull credential cannot change WHAT runs. Pinned anyway — 'only the committed shape' is the
premise, and the rule costs four lines.
kyverno test: 33 passed, 0 failed (was 28). Three new fixtures, each a real path: the
committed entry plus a second one, a different Secret, and none at all.
The gate also caught me shipping the Secret in plaintext — I never ran sops -e -i on the
placeholder. Recorded in the handoff entry, because the file looked finished.

Operator decision on PR #81: no CI job may reach a privileged daemon. The act runner is untouched.
- platform/buildkit (+ clusters/base/buildkit.yaml): moby/buildkit v0.34.1-rootless pinned by
digest, uid 1000, not privileged; caps drop ALL + SETUID/SETGID, seccomp/AppArmor Unconfined,
read-only rootfs (each measured under podman). cert-manager CA + server/client certs, ClusterIP
:1234, default-deny with ingress only from the act-runner pod (DinD masquerades jobs to it).
No Kyverno exception: every applied policy matches app-namespace=true only.
- Each Containerfile names its shipped stage and ends in a `verify` stage holding every former
`docker run` assertion (uid 65532, RUN --network=none, writable-path inventory standing in for
the read-only rootfs). The old `&& echo` checks that could never fail are real assertions now.
- images.sh drives buildkitd with a pinned buildx (sha256-checked) via bake; PRs build verify
targets with agent-runner FROM the in-run toolbox (target: context); main verifies, then pushes.
Fails loudly when the builder secrets are absent or buildkitd is unreachable.
- infra/gitea/buildkit-client-secret.sh copies the client cert into Actions secrets.

Operator rule 2026-10-29: image creation, hosting and lifecycle belong to CI/CD, never to a
workstation build/push. Nothing had ever been pushed to the Gitea registry.
- .gitea/workflows/images.yaml + scripts/images.sh: PRs build+verify (no credential); main
builds, verifies and pushes toolbox, agent-runner (FROM toolbox) and conformance-runner as
sha-<commit> + main, reading the digest back from the registry. Only changed images build.
- Each image's own build-image.sh does the build and in-image verification, now engine-neutral
(DinD: no podman-only calls, probe over stdin not a bind mount). New toolbox build-image.sh.
- Digest references carry `# renovate-digest:` markers; renovate.json5 gains a custom.regex
manager for them. The worker Job template is deliberately untracked (it would loop).
- renovate.yaml pins renovate-version 44.167.0: the action's default (39.264.0) rejects the
current config's managerFilePatterns, so every run would have died at CONFIG_VALIDATION.
- Push credential: REGISTRY_PUSH_TOKEN secret; the Actions token has no package scope in
Gitea 1.24.3 (container.go Authenticate). Retention: infra/gitea/registry-retention.sh.

Node configuration in this project is Ansible's — declared in the inventory, reviewed,
version-controlled — and for prod it is the ONLY surface: infra/PROD-PROVISIONING.md
records prod as 3x bare metal with the dev OpenTofu -> Proxmox -> cloud-init path
explicitly not applying, so there is no tofu/cloud-init half to keep in parity for an
/etc/hosts pin.
The pin was already in the right place; what the docs lacked was the command. All four
places now carry the scoped, idempotent one:
cd infra/ansible && ansible-playbook playbooks/node-baseline.yml \
-e k3s_hosts=k3s_prod --tags hosts
--tags hosts runs ONLY the /etc/hosts task, so applying this pin cannot drift any other
baseline setting.
Also verified the mechanism is not inert, which is the failure mode this repo keeps
meeting: roles/node_baseline/tasks/main.yml renders node_baseline_hosts_pins into a marked
blockinfile with backup: true, and state: absent when the list empties — so a removed
entry really does leave the node.

The pm-agent image pull failed TLS verification, and the previous entry on this branch
recorded it honestly as not diagnosed. Diagnosed now, and it is not about the image.
containerd pulls as a NODE process, so it resolves through node_baseline_dns_servers (the
LAN gateway, deliberately not PiHole) and gets the public answer: a CNAME to
wan.home.keithjackson.dev -> 136.51.115.252, measured via both 1.1.1.1 and 8.8.8.8. This
router does not hairpin, so WAN:443 answers with its own placeholder certificate —
measured with the right SNI from the workstation:
subject=C=ZZ, ST=Somewhere, L=Unknown, O=%D342e7e6b, CN=%D
No extensions in certificate
No extensions means no subjectAltName, which is exactly 'certificate is not valid for any
names'. Meanwhile 192.168.2.20 IS the shared Gateway's VIP and its https listener serves
the real Let's Encrypt *.home.keithjackson.dev. The Gateway, the wildcard cert and the
digest were never implicated — only the node's answer.
This file already documents the identical failure for the Keycloak issuer, measured from
k3s-prod-2/-3 on 2026-10-03 (curl exit 60, ssl_verify_result=18), and already carries the
mechanism that fixes it. gitea is simply the second node process to need it; containerd is
a node process and nobody had added it. An operator must run the node_baseline play.
Also records, where an operator reads them, that the agent authenticates to Gitea with a
local account and a scoped PAT by decision — and why the federated alternative is not
merely unchosen but unavailable: Gitea implements only the Authorization Code Grant and
validates no third-party OIDC token, so a Keycloak service-account token cannot
authenticate to its API or to git-over-HTTP.

An in-cluster consumer reaches a service by its *.svc.cluster.local name, which is by
design a different path from how a client outside the cluster reaches the same service.
pm-worker's host allowlist accepted TWO values: the cluster-local name and the external
hostname gitea.home.keithjackson.dev. The second is removed.
It was never needed — nothing sets it — it would route in-cluster traffic out through the
Gateway and back for no reason, and as an ACCEPTED value it widened the allowlist to a
host reachable over the namespace's world:443 egress rule, which is precisely the
injection shape the allowlist exists to refuse.
probe-validation.sh now pins that: 20 refusals, including the external hostname, the
cluster-local name over https, and the cluster-local name on the wrong port.
Also corrects a remark in the handoff entry: I cited cluster-vars' GATEWAY_VIP
(192.168.1.53) as suspicious next to the nodes' 192.168.2.x. That was noise — those base
cluster-vars values are dev-era leftovers for a decommissioned cluster and say nothing
about prod. None of the measured facts depended on it.

pm-agent reconciled exactly as designed after #57: Flux applied main@sha1:95597bd to
platform-config, pm-agent and apps-wave-0 (all Ready), the ClusterPolicy
pm-agent-job-shape is live with Enforce + failurePolicy Fail and all six rules, SOPS
decryption works through the new overlay patch (checked by key names and value lengths,
never values), and pm-agent-worker really is bound to nothing.
Measuring it turned up two prerequisites for the NEXT operator step that nothing in this
repository declares, and that #57's handoff could not have known — it listed the image
pull as unverified, and that is exactly where it bit:
- the nodes cannot verify the registry's TLS certificate (containerd: 'x509: certificate
is not valid for any names'), while the same name serves a healthy Let's Encrypt
wildcard from the LAN. A correct digest fails identically;
- an unauthenticated client gets nothing from this Gitea's registry (its anonymous token
carries no access scope) and no imagePullSecret exists anywhere in the tree.
Not specific to pm-agent: conformance-runner shares the registry path and has never been
pulled either. The dispatcher is the first workload in the cluster ever to reference it.
Documentation only — no manifest, no policy, no code. Both fixes need an operator action
and one of them is a posture decision, so the docs present both rather than pick.

pm-worker's command is pinned by admission with no args, so everything a caller could
influence arrives in the environment — and the guards at the top of that script are what
stand between an injected variable and a clone from the wrong host or a push to the
wrong ref. Nothing exercised them, which makes them a claim rather than a control.
probe-validation.sh asserts 17 refusals, each on BOTH a non-zero exit and the specific
message, so a guard that stopped firing cannot pass by failing somewhere else. It covers
a redirected git host, a real and reachable WRONG one (the egress policy permits tcp/443,
so that case is not hypothetical), the right host with a smuggled path, 'main' and five
other bad branch shapes, a malformed owner/repo, a bad mode, a bad issue number, and each
missing credential. build-image.sh runs it inside the built image too.
Writing it found three things:
- the PM_BRANCH != main guard is unreachable while the pattern check above it holds, so
the comment claiming it as the defence was wrong about which line does the work. Kept
as an assertion independent of the regex; the comment now says so.
- the EXIT trap ended in a failing test, which under set -e can replace the script's
real exit code with that failure.
- a provenance LOG LINE read a file through a redirect that set -o pipefail would have
turned into a dead worker if the file were absent.

A service that reads this repository's Gitea issues, decides what to do about each
thread as the Program Manager persona, and runs one worker agent per assignment that
authors a change, runs the merge gate and opens a pull request. It reacts to issue
creation and to comments; the assignment and all correspondence travel through the
issue thread and the PR. It authenticates with an Anthropic subscription token. It
never pushes to main and never merges.
Three choices carry the design, with alternatives recorded in docs/plans/:
- it POLLS rather than receiving webhooks (Gitea's webhook SSRF guard, lost
deliveries, and no inbound reach needed at all);
- it keeps NO state: the trigger is "the newest thing in this thread was not
written by me", so the issue thread is the state — no PVC, no backup obligation;
- the model holds NO tools: its reply is one JSON object this code validates, so
nothing in the path executes text.
The boundary is platform/kyverno/admission/pm-agent-job-shape.yaml (Enforce,
failurePolicy: Fail), not the RBAC: Kubernetes places no `use` check on
serviceAccountName, so "may create Jobs" is "may run arbitrary code as the
namespace's most privileged identity". Six rules admit only the committed shape, and
the worker identity is bound to nothing with no token mounted, so there is nothing to
escalate to. 28/28 offline Kyverno assertions.
Nothing has run: the image has never been built or pushed, and both the image digest
and the two credentials are deliberate placeholders. See the handoff entry's
"What I did NOT verify".
