## Step 0 — Branch and scaffold

Branched off the unborn `main`:

```bash
git checkout -b feat/proxy-operator
```

Installed kubebuilder v4.15.0 into a scratch `GOBIN` rather than the default
`$(go env GOPATH)/bin`, since the module's package layout changed and
`go install .../cmd/kubebuilder@v4.15.0` (the path from the plan) 404s — the binary is
now the module root itself:

```bash
GOBIN=<scratch>/bin go install sigs.k8s.io/kubebuilder/v4@v4.15.0
```

Scaffolded in place, with `kubebuilder` on `PATH`:

```bash
kubebuilder version
# KubeBuilder: v4.15.0, Kubernetes: 1.36.0

kubebuilder init --domain example.com \
  --repo gitea.home.hrajfrisbee.cz/kacerr/egress-proxies-operator --plugins go/v4
# WARN: target directory not empty (expected — CLAUDE.md, docs/, .claude/ already existed)

kubebuilder create api --group crawl --version v1alpha1 --kind Proxy \
  --resource --controller
```

`create api` auto-ran `make manifests` at the end, which pulled and ran
`controller-gen` itself:

```bash
sigs.k8s.io/controller-tools/cmd/controller-gen@v0.21.0
"$(bin)/controller-gen" object:headerFile="hack/boilerplate.go.txt",year=2026 paths="./..."
```

Confirmed the CRD group landed correctly (no doubling — `--domain example.com
--group crawl` was used specifically to avoid the `crawl.crawl.example.com` trap
called out in the plan):

```bash
grep -A2 "GroupVersion =" api/v1alpha1/groupversion_info.go
# SchemeGroupVersion = schema.GroupVersion{Group: "crawl.example.com", Version: "v1alpha1"}
```

Dropped the scaffolded GitHub Actions workflows (remote is Gitea, not GitHub):

```bash
git rm -r --cached .github 2>/dev/null; rm -rf .github
```

Ran the full manifest/codegen pass once more to confirm the toolchain is reproducible
end to end:

```bash
make manifests generate
# controller-gen rbac:roleName=manager-role crd webhook paths="./..." output:crd:artifacts:config=config/crd/bases
# controller-gen object:headerFile="hack/boilerplate.go.txt",year=2026 paths="./..."
```

then `go build ./...` and `go vet ./...`, both clean with no output.

Worth noting: `CONTROLLER_TOOLS_VERSION` in the generated `Makefile` came out at
`v0.21.0` by default in this kubebuilder release, so the Makefile edit the plan
anticipated wasn't needed. Pre-existing `CLAUDE.md`/`CHANGELOG.md` content survived
untouched; kubebuilder added its own `README.md`, `AGENTS.md`, `.golangci.yml`,
`.devcontainer/`, `Dockerfile` on top of them — those get edited or left as-is in
later steps. Committed as `076bc66`.

## Step 1 — API types (`api/v1alpha1/proxy_types.go`)

Wrote the full `ProxySpec`/`ProxyStatus`/`Proxy` types per the plan, including the
four corrections called out there (`MaxLeases *int32`, `HealthCheck` with
`+kubebuilder:default={}`, `MinLength=1` on `Provider`/`CloudInit.Inline`,
`Conditions` with `+listType=map`), the 7 CEL `XValidation` rules (6 on `ProxySpec`,
1 on `CloudInitSpec`), and pure helpers in `helpers.go`
(`EffectivePort`/`EffectiveHost`/`HealthCheckOrDefault`/`MaxLeasesOrDefault`) with
table-driven tests in `helpers_test.go`.

Regenerated deepcopy and the CRD:

```bash
make manifests generate
# controller-gen rbac:roleName=manager-role crd webhook paths="./..." output:crd:artifacts:config=config/crd/bases
# controller-gen object:headerFile="hack/boilerplate.go.txt",year=2026 paths="./..."
```

Confirmed all 7 CEL rules and the `healthCheck` `default: {}` block landed in the
generated CRD as expected:

```bash
grep -B1 "rule:" config/crd/bases/crawl.example.com_proxies.yaml
# 7 matches, one per XValidation marker written
```

Ran the full suite, not just `go build`/`go vet`, since this was a good opportunity to
confirm envtest itself works end to end for the first time:

```bash
make test
# Setting up envtest binaries for Kubernetes version 1.36...
# .../bin/k8s/1.36.2-darwin-arm64   (confirms the plan's envtest version note)
```

This failed on the first run — not because of anything in the new types, but because
kubebuilder's scaffolded placeholder test in `proxy_controller_test.go` creates a bare
`Proxy{}` with no `spec.mode`, which our new required/enum field correctly rejects:

```text
Proxy.crawl.example.com "test-resource" is invalid: [spec.mode: Unsupported value: "":
supported values: "Managed", "External", ...]
```

That's a real envtest apiserver enforcing our schema for the first time, which is
useful confirmation on its own. Patched just the resource literal in that scaffold
test to a minimal valid spec (`Mode: External` + `Endpoint.Host`) rather than
rewriting the file — that whole test gets replaced in Step 4 alongside the real
reconciler, so a deeper fix now would be thrown away. `make test` then passed clean:
`api/v1alpha1` at 20.5% coverage (helpers only — CEL itself isn't unit-testable, it's
exercised by the real apiserver as shown above), `internal/controller` at 66.7%.

Worth noting: the `go test ./...` command from the plan's own verification section
does *not* work directly for the envtest suite — it needs `KUBEBUILDER_ASSETS` set,
which only `make test` does via `setup-envtest`. Plain `go test ./...` fails the
`internal/controller` package with a `/usr/local/kubebuilder/bin/etcd: no such file`
error that has nothing to do with the code. Use `make test`, not `go test ./...`,
whenever the controller package is in scope.
