gate / gate (pull_request) Successful in 1m35s
gate / conformance (pull_request) Has been skipped
feat(ci): the pipeline is the approver; humans approve changes to the pipeline
Implements the operator intent: "CI/CD pipeline is the end-all-be-all for approval. If
the CI pipeline is not good enough to be trusted for this, then it is not good enough to
do its intended job and needs to be improved. Manual approvers should only be for
architecturally or security relevant changes."

Adds ci/approval-policy.sh as a gate stage. A green gate becomes sufficient for an
ordinary change; the one exception is structural rather than a matter of taste:

  A CHANGE TO THE GATE CANNOT BE GATED BY THE GATE.

A PR that weakens a check would be approved by the weakened check. The same holds for the
admission policies, the Flux wiring that decides what reconciles, the SOPS recipients and
the RBAC. Those paths -- and only those -- still require an APPROVED review from someone
other than the author.

The list is data with a reason per entry (infra/gitea/approval-policy.json) and is itself
a sensitive path, so the policy cannot be widened or narrowed without a human.

FAIL-CLOSED, and deliberately the opposite of gitea-settings. There, a missing credential
must not block every PR -- that is a lock-out. Here, a missing credential would let an
unreviewed change to the gate merge, so "cannot evaluate" is a BLOCK.

Verified against real PRs rather than fixtures:
  PR #16 (sensitive paths, approved by jakman85, author gitea-admin) -> PASS
  PR #6  (.gitea/workflows/gate.yml, ZERO reviews)                   -> BLOCK, naming the file
  push event (not a PR)                                              -> N/A, exit 0
  bogus token                                                        -> BLOCK, not skip

Also caught before shipping: the first draft passed the PR file list with a second stdin
redirect after a heredoc, which silently wins and leaves the script body unread. Running
it found that; reading it would not have.

required_approvals is NOT changed here. Flipping it live must happen together with the
declaration in expected-branch-protection.json, or gitea-settings correctly fails on the
drift -- that is a separate, deliberate change.

infra/ — node provisioning and the toolchain

OpenTofu (Proxmox VE) + cloud-init + Ansible bring up the 3-node k3s/Cilium dev cluster. Spec: ../home-network-k3s/docs/02-environments-and-provisioning.md.

Path What
tofu/ The "Create" stage: 3 cloud-init'd VMs on the Proxmox box (bpg/proxmox provider)
cloud-init/ First-boot baseline shipped as a Proxmox user-data snippet
ansible/ The "Baseline"/"Configure" stages: k3s HA, Cilium, kube-vip, the VPN egress gateway
devcontainer/ The pinned toolchain (tofu, ansible, sops, age, flux, kubectl, helm and the whole CI gate toolchain)
cluster.sh RETIRED — drove the old libvirt VMs; does not work against Proxmox
PHASE1-STATUS.md Current state of the cluster and how to reconnect to it
PHASE1-SCOPE.md Historical Phase-1 scoping doc (libvirt era — superseded)

Where the cluster actually lives

The dev cluster is not on this workstation. It runs on a Proxmox VE host; the nodes sit on the Proxmox LAN and are reached across a pfSense NAT:

Nodes k3s-dev-1/2/3 at 192.168.1.50/.51/.52 — 6 vCPU, 24 GiB, Debian 13, k3s v1.36.4
kube-API kube-vip VIP 192.168.1.49:6443, reached from the workstation via NAT 192.168.2.50:6443
Node SSH pfSense NAT 192.168.2.102:2250/2251/2252 → node :22 (Ansible only)
Ingress VIP 192.168.1.53 (Cilium L2, shared Gateway); .53–.60 reserved for LB VIPs

The earlier libvirt/KVM cluster on 10.73.0.0/24 is retired. Any doc or command referencing virsh, qemu:///system, or 10.73.0.x for the cluster is historical.
