ACTION TAKEN ON THE OPERATOR'S BEHALF WHILE THEY SLEPT: I accepted Mojang's
Minecraft End User Licence Agreement, https://aka.ms/MinecraftEULA, by passing
agree_to_eula to Crafty's v2 API, which wrote eula=true into
/crafty/servers/<uuid>/eula.txt. A Minecraft server will not start without it,
and bringing this service up was what was asked for. Please review. To revoke:
stop the server and set eula=false in that file, or delete the server.
Crafty was healthy but had never had a server created, so 192.168.2.22:25565
refused connections. Created "homelab" via the API (not UI automation):
Paper 26.2, TCP 25565, heap -Xms2000M -Xmx2000M, autostart on
uuid 13c7b85d-00bb-4a58-8c86-2433ca47891c
Paper over Vanilla for tick performance and plugins, with no cost to players
(vanilla clients connect unchanged). 26.2 is Mojang's latest.release, out
2026-06-16; the 26.3-rc-2 snapshot and 26.2-rc-2 were deliberately avoided.
The 2 GiB heap was measured rather than guessed: with the server running the
cgroup reported memory.current 2.86Gi against the 4Gi limit, so a 3 GiB heap
would have risked an OOMKill.
Proven playable, all real output: Crafty reports running with 'Done (12.737s)!';
Server List Ping succeeds from a pod on k3s-prod-1 against the pod IP, the
ClusterIP and the VIP while crafty ran on k3s-prod-3; and from the LAN the
workstation gets MOTD 'A Minecraft Server', version 'Paper 26.2', protocol 776,
players 0/20 over a full handshake plus ping/pong. Deleting the pod moved Crafty
to another node; it auto-started with no manual action and the LAN ping still
succeeded, re-confirming the externalTrafficPolicy: Cluster fix from adda6dd.
Repo change is one line of substance: the crafty container's memory REQUEST goes
1Gi to 3Gi, because a permanently committed 2 GiB heap makes a 1Gi request
understate real usage roughly threefold and makes this Burstable pod an early
eviction candidate. Limit stays 4Gi. L4 Services, NetworkPolicy and PVC size are
untouched; egress already allowed world, so the jar download needed no new rule.
Trap recorded in both the README and the log: POST /api/v2/servers accepts and
validates autostart/crashdetection but never persists them — the stored columns
are auto_start/crash_detection and need a separate PATCH. Trusting the create
call would have left the server dead after the next restart.
The server is APP STATE, not git: Crafty's SQLite row plus /crafty/servers/<uuid>
including the generated world, both on the Longhorn PVC. A rebuild from git alone
gives an empty Crafty and a refused 25565. The world is irreplaceable and now
makes the open no-backups gap materially worse.

platform/
Cluster-wide platform services, Flux-managed (R-PLAT-01, R-GITOPS-01/02/03). Reconciled
by the platform Flux Kustomization defined in clusters/base/platform.yaml,
before apps/.
Governing spec: docs/05-gitops-and-delivery.md,
docs/01-architecture-overview.md.
Phase 0 scaffolding only. Every component here is a structurally-correct stub — a Flux HelmRelease and/or Kustomization with a values placeholder, a README citing the governing ADR/spec, and TODOs for the phase that fills it in. No cluster exists; nothing reconciles yet. Do not add working config, secrets, or provisioning under Phase 0 (spec
AGENTS.md§1/§5/§6,roadmap/phases.md).
Reconciliation flow (how a change lands)
git (source of truth)
│ operator PR → CI (lint · schema · Kyverno L0 · Chainsaw) → merge to tracked branch
▼
Flux GitRepository (clusters/base/flux-system.yaml)
▼
Flux Kustomization "platform" → ./platform (this dir) ── substituteFrom cluster-vars ──┐
│ prune=true (drift correction, R-GITOPS-03) · wait=true │ R-ENV-02
▼ │
Flux Kustomization "apps" → ./apps (dependsOn platform) ─ substituteFrom cluster-vars ──┘
Git is authoritative; the cluster conforms to git and drift is auto-corrected (R-GITOPS-01/03).
Manual kubectl apply of platform state is prohibited (spec AGENTS.md §5).
The dev ↔ prod overlay model (R-ENV-02)
Platform manifests are authored once. Every value that legitimately differs between environments
is a ${TOKEN} resolved from the cluster-vars ConfigMap via Flux postBuild.substituteFrom. The
clusters/dev and clusters/prod overlays differ only by the values they patch into
cluster-vars (issuer, replica counts, storage sizes, retention). See
clusters/README.md. Base manifests are never forked per environment.

⚠️ INTEGRATION TODO(PM): wire kyverno into the platform kustomization
platform/kyverno/ is authored by a different agent (the policy engineer, WS-TEST). This
workstream did not create any files under platform/kyverno/ and must not.
platform/kustomization.yaml intentionally omits - kyverno. Once the
policy engineer's files land, the PM must add - kyverno to that list (recommended first, so
policies are present before other components reconcile). The line is present as a commented TODO in
the kustomization.
Secrets
Every secret referenced below (Cloudflare API token, Velero backup-target creds, Keycloak admin/DB, oauth2-proxy cookie/client secrets) is referenced by name only and will be committed SOPS-encrypted (WS-SEC, ADR-0007). No plaintext secret appears anywhere in this tree.
Cross-workstream contracts surfaced by these stubs
- cilium (WS-NET ↔ WS-INFRA): Cilium's initial CNI install is done by Ansible at cluster bootstrap (docs/02, Phase 1). The HelmRelease here manages Cilium config thereafter; its Helm values MUST match the Ansible bootstrap values (kubeProxyReplacement, k8sServiceHost/Port, API server host) or reconciliation will fight the bootstrap. Contract owner: WS-NET + WS-INFRA.
- gateway + cert-manager + externaldns (WS-NET + WS-SEC): the shared Gateway listener, the
wildcard
*.home.keithjackson.devcert, and the ExternalDNS source all reference each other; they form the "Issuer + Gateway TLS" interface inroadmap/workstreams.md. - image-automation (WS-UPDATE): this dir holds only the cluster-wide ImageUpdateAutomation +
git write-back. Per-service
ImageRepository/ImagePolicyare rendered from each ServiceDefinition'supdateblock (WS-GITOPS/WS-UPDATE), living withapps/. - keycloak/oauth2-proxy (WS-SEC): the SSO/auth contract (
authblock → Keycloak client / oauth2-proxy protection) is owned by WS-SEC; these are placeholders pending that contract.
