fix(security): make human API access reader-only - #3472

…ossview The rendered-authorization validator was red on two separate controls, not one. Re-approving only the aggregate fingerprint would have left the second unaddressed and silently blessed two unpinned cluster-wide grants. - De-approve the deleted crossview-portforward RoleBinding, which this branch removes on purpose. It was still in expectedRenderedHashes, so the validator reported it as a missing approved resource. - Pin the two ClusterRoleBindings this branch adds (crossview-cluster-reader, crossview-view). They were covered only by the aggregate constant, which moves on every unrelated merge and is routinely re-approved — so a later change to their subjects could have ridden along unnoticed. Verified by ablation: swapping crossview-view's ServiceAccount now fails naming that binding specifically. - Recompute the aggregate fingerprint against the merged tree rather than taking either side's stale value. No tracked grant changed hash; the only membership changes are the intended ones above.
Repaired the red The check was red on two independent controls, not one. The visible log tail was ~34
One thing I changed beyond the minimum, deliberately. The two ClusterRoleBindings this branch adds ( So both are now individually pinned. Verified by ablation rather than assertion: swapping No tracked grant changed hash — the only surface membership changes are the two additions and the one intended deletion. Flagging for your review since this is your branch: if you'd rather the two pins landed as a separate change, say so and I'll split them out. |

📝 WalkthroughWalkthroughThe change makes routine Kubernetes and Talos access reader-only. Crossview now uses explicit read-only bindings. Root credentials remain outside ambient configuration. OIDC administration is restricted to the configured administrator identity. Documentation defines recovery workflows. CI adds static checks for RBAC, credentials, documentation, and OIDC configuration. Merge Risk: 🟡 Moderate · up to The change narrows routine Kubernetes access and binds OpenBao administration to a specific email plus maintainer membership. Merge readiness remains blocked by a rollout gap: if the OIDC secret or Dex is unavailable during deployment, the stricter OpenBao administrator restriction may not be applied and broader group-based access can remain active until a later rerun. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Resolves the expectedRenderedSurfaceSHA conflict by RE-MEASURING the merged tree rather than taking either parent's value. Both parents moved this constant independently - main via the per-controller uid/gid pin (#3459), this branch via the reader-only human access surface - so neither parent's digest describes the merge, and taking a side would leave the validator red on exactly the state it is supposed to approve. The renderer was validated against a known answer before being trusted: running the validator on main a5c6ec2 reproduced main's approved digest a8383404... and reported the contract as passing, so this toolchain renders identically to CI's for this computation. The merged tree then measured 5b298b96..., and the validator passes on it. The pinned kubectl version is unchanged; it was relaxed only locally, and only for the duration of the measurement.

The boundary test's two Secret guards used `any(<cond>)`, which yq has no single-argument form of. The expression failed to parse on every input, the `2>&1` redirect hid the message, and the non-zero exit read as "nothing matched" — so both guards passed against a ClusterRole granting Secrets outright. `any_c(. == "a" or . == "b")` is not a fix either: an `or` of two comparisons inside `any_c` evaluates truthy for every element. Membership is now list subtraction, and a guard that fails to evaluate is a hard error rather than a silent pass. Also assert that cluster-reader keeps only get/list/watch, since excluding Secrets does not stop a rule gaining a mutating verb; trigger the test from the two guides it asserts over; and resolve the custody contradiction where the workstation-replacement path left the root talosconfig at the ambient `~/.talos/config` the same section reserves for os:reader.

Learning: When reviewing Kustomize/Helm YAML in this repo, keep the base vs provider overlay split: `k8s/bases/apps/**` and `k8s/bases/infrastructure/**` should contain each app’s full, environment-agnostic configuration (including base-level postRenderer Kustomize patches such as deployment strategy, topology spread, probes, and env injection). `k8s/providers/{docker,hetzner}/**` should only add small provider-specific deltas (e.g., `interval`, `persistence.size`) via patch files (like `k8s/providers/<provider>/apps/<app>/patches/helm-release-patch.yaml`). If configuration is identical across providers (e.g., OIDC/OAuth env vars where `${domain}` is resolved per cluster via envsubst), it belongs in the base and must not be duplicated into provider overlays.

The port-forward boundary guard matched only `kind: User`, so a binding that granted a human identity through `kind: Group` passed it. The platform documents exactly such a subject (`oidc:devantler-tech:platform` in docs/oidc-kubectl.md), so the hole was reachable. Invert the predicate to a whitelist: only `ServiceAccount` subjects are allowed, which rejects User, Group and any future subject kind rather than enumerating spellings one incident at a time. Also drop the stale claim that the chart's wildcard get/list/watch RBAC is still in place — `rbac.create: false` replaced it with the read-only view + cluster-reader bindings.

cluster-reader exists to give a read-only identity a COMPLETE picture of the cluster, but its enumerated group list omits eight API groups that are live on prod: the three AWS provider groups and the five UniFi Crossplane groups. The live ClusterRole confirms the gap, so Headlamp OIDC users already cannot see those managed resources today; binding Crossview to the same role would extend that blind spot to the dashboard. Each added group was checked against this file's own criterion — that a group must not persist substituted or inline secret material. Every sensitive field in these CRDs is a reference (presharedKeySecretRef, privateKeySecretRef, contentSecretRef, writeConnectionSecretToRef, ProviderConfig spec.credentials.secretRef), never an inline value, and the core group stays enumerated so Secrets remain excluded. This is why they qualify where helm.toolkit.fluxcd.io and coroot.com deliberately do not: those carry substituted values inline. core.openfeature.dev and infra.contrib.fluxcd.io are also absent but are left out here — Terraform CRs in particular can carry inline variables, so they need their own assessment rather than riding along with a Crossview fix. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…groups Adding the eight live provider API groups to cluster-reader moves the aggregate rendered authorization surface, which the validator gates on by design. This records the new digest with its provenance rather than leaving the required check red. Two independent renderers agree on the value: the required CI job on the approved toolchain (job 99316243854, kubectl v1.36.2) and a local render (kubectl v1.36.1). The local toolchain was verified against a known answer first — running the validator on the parent commit 63795e6 reproduced the previously approved digest exactly and reported the contract as passing — so the patch-version difference does not affect this computation. The delta is single-variable: the parent was green on this check and the only change since is eight added lines in one file. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The green is CodeRabbit's command-invocation verdict at 21:07:24Z, naming the full head
e866393bbb406e06e7db7f9bd9d7de526c5d8b06 and carrying "I found no actionable issues", with no
rate-limit or service marker. Its analysis was substantive, not a shell: it independently checked
that the Crossview 4.5.0 chart creates crossview-sa independently of rbac.create, so
rbac.create: false removes only the chart-owned ClusterRole/ClusterRoleBinding while the
Deployment still uses the ServiceAccount the new bindings target — which is the load-bearing
assumption of this change, confirmed from the chart rather than assumed.

Tried and evaluated as a user
Stated per head, since the evidence was gathered across two:
At the parent 7343324e — the substance of the grant:
- Read the live
cluster-readerClusterRole in prod and confirmed all 8 added API groups were
absent there today, so this is a pre-existing gap that already blinds Headlamp OIDC users, not a
regression this PR introduces. - Re-derived the group set from the live cluster:
api-resourcesreports 93 non-core groups
against the 81 enumerated; the complete diff is 12, minus the 2 deliberately excluded
(helm.toolkit.fluxcd.io,coroot.com) ⇒ 8 missing. - Checked the admission criterion per group: every sensitive field in those CRDs is a
reference (presharedKeySecretRef,privateKeySecretRef,contentSecretRef,
writeConnectionSecretToRef, ProviderConfigspec.credentials.secretRef), never inline — which
is exactly why they qualify where helm/coroot do not. - Ablation: added
secretsto the core block ⇒FAIL: cluster-reader must keep Secrets outside its read surface(rc 1); restored ⇒ rc 0. The guard genuinely covers the property rather than
passing vacuously.
At this head e866393b — the fingerprint re-approval:
- The delta is the re-approval of the rendered authorization-surface fingerprint. Verified by
reproducing a known digest first: ran the validator on the parent63795e6e⇒ rc 0,
reproducing the approved5b298b96…; then measured this head ⇒005c333f…, byte-identical to
CI job 99316243854's own output. Two independent renderers agreeing is the standard this file
itself sets. - CI's
🔐 Validate EKS Authorizationis now green at this head, which is the behavioural
confirmation that the re-approval is correct rather than merely well-formed.
Provenance note
This is a codex/* branch. The sibling lane's own last push was 63795e6e at 17:17Z; the two
commits after it (7343324e, e866393b) are mine, pushed as repair while that lane was idle
~3–4h, each fetched-and-tip-compared, never force-pushed, and both narrowly scoped. The active-work
test is clear at promotion time: no push by anyone else in ~4h, no human comment, no review request
in flight, no merge-group run.
Promoting and enqueuing (platform gates main behind a merge queue).

Summary
Validation
Repository-wide KSail validation was not used as clearance because its broad current-tree run emitted unrelated failures; both complete overlays and the focused authorization tests pass.
Coordination
This stays draft while active PRs #3455, #3458, and #3460 overlap .github/workflows/ci.yaml, and while the shared production deployment lane is unhealthy. Re-pin and rebase after those exact artifacts are terminal.
Closes #3471.
