Component-level architectural correction (two changes): 1. MinIO → SeaweedFS as unified S3 encapsulation layer The old design used MinIO for in-cluster S3 plus separate cold-tier configuration scattered across consumers. The new design positions SeaweedFS as the single S3 encapsulation layer: every Catalyst component talks to one endpoint (seaweedfs.storage.svc:8333). SeaweedFS internally handles hot tier (in-cluster NVMe), warm tier (in-cluster bulk), and cold tier (transparent passthrough to cloud archival storage — Cloudflare R2 / AWS S3 / Hetzner Object Storage / etc., chosen at Sovereign provisioning). One audit/lifecycle/encryption boundary instead of N. No Catalyst component talks to cloud S3 directly anymore — Velero, CNPG WAL archive, OpenSearch snapshots, Loki/Mimir/Tempo, Iceberg, Harbor blob store, Application buckets all share one S3 surface. 2. Apache Guacamole added as Application Blueprint §4.5 Communication Clientless browser-based RDP/VNC/SSH/kubectl-exec gateway. Keycloak SSO, full session recording to SeaweedFS for compliance evidence (PSD2/DORA/SOX). Composed into bp-relay. Replaces VPN+native-client distribution for auditable remote access. Component changes: - DELETED: platform/minio/ - CREATED: platform/seaweedfs/README.md (unified S3 + cold-tier encapsulation; bucket layout; multi-region replication via shared cold backend; migration-from-MinIO section) - CREATED: platform/guacamole/README.md (clientless remote-desktop gateway; GuacamoleConnection CRD; compliance integration via session recordings) Doc updates: PLATFORM-TECH-STACK §1+§3.5+§4.5+§5+§7.4; TECHNOLOGY-FORECAST L11+mandatory+a-la-carte counts (52 → 53); ARCHITECTURE §3 topology; SECURITY §4 DB engines; SOVEREIGN-PROVISIONING §1 inputs; SRE §2.5+§7; IMPLEMENTATION-STATUS §3; BLUEPRINT-AUTHORING stateful examples; BUSINESS-STRATEGY 13 component-count anchors + Relay product line; README.md backup row; CLAUDE.md folder count. Component README updates (S3 endpoint + dependency renames): cnpg, clickhouse, flink, gitea, iceberg, harbor, grafana, livekit, kserve, milvus, opensearch, flux, stalwart, velero (substantive rewrite of velero — now writes exclusively to SeaweedFS with cold-tier auto-routing). Products: relay, fabric. UI scaffold: products/catalyst/bootstrap/ui/src/shared/constants/components.ts — minio entry replaced with seaweedfs; velero+harbor deps updated; new guacamole entry added. VALIDATION-LOG entry "Pass 104 — MinIO → SeaweedFS swap + Guacamole add" captures the encapsulation principle and adds Lesson #22: storage tier policy belongs at the encapsulation boundary, not inside every consumer. Verification: zero remaining MinIO references in canonical docs (one intentional retention in TECHNOLOGY-FORECAST L37 explaining the swap); 53 platform/ folders matching all "53 components" anchors; bp-relay composition includes guacamole.

OpenOva Catalyst
A self-sufficient Kubernetes-native platform. Published as signed OCI Blueprints. Deployable as your own Sovereign.
Catalyst is the open-source platform built by OpenOva. It turns any Kubernetes cluster into a Sovereign: a self-contained control plane that hosts Organizations, Environments, and Applications via GitOps + Crossplane, with a unified UI/Git/API for users.

The model in 60 seconds
OpenOva (the company) publishes Catalyst (the platform).
A deployed Catalyst is called a Sovereign.
A Sovereign has:
- Organizations (multi-tenancy unit)
- Environments (org-scoped, env-typed: prod/stg/uat/dev/poc)
- Applications (installed Blueprints)
- Blueprints (the App Store catalog — public + Org-private)
Users install Applications from Blueprints into Environments.
Blueprints can depend on Blueprints (arbitrary depth).
Each Environment is one Gitea repo + one or more vclusters.
Every state change is a Git commit.
Every UI surface reads from a single CQRS projection.
Same code runs in every Sovereign:
- openova (run by us; SaaS Organizations)
- omantel (run by Omantel; SME Organizations across Oman)
- bankdhofar (run by the bank; internal Organizations)
- your-company (run by you, on infrastructure you choose)
See docs/GLOSSARY.md for every term, docs/ARCHITECTURE.md for the full picture.

Each folder under platform/ and products/ is the source of one Blueprint, published from CI as a signed OCI artifact at ghcr.io/openova-io/bp-<name>:<semver> (the bp- prefix is added to the OCI artifact name; folder names stay short). Per-folder isolation is provided at the OCI artifact layer, not the Git repo layer — this is a monorepo with per-Blueprint fan-out, not a meta-repo of separate Git repositories. See docs/BLUEPRINT-AUTHORING.md §2 for the folder layout contract.
Today, every folder under
platform/andproducts/(exceptproducts/axon/) contains only aREADME.md. The Blueprint manifests, charts, Compositions, and CI fan-out are all design-stage — seedocs/IMPLEMENTATION-STATUS.md.

Cloud providers
| Provider | Status |
|---|---|
| Hetzner Cloud | Available (most-tested path) |
| AWS / GCP / Azure | Crossplane providers available; full path coming |
| Oracle Cloud (OCI) | Crossplane provider available; full path coming |
| Huawei Cloud | Crossplane provider available; full path coming |
All providers reach Catalyst via the same Crossplane abstraction; Sovereign provisioning details per provider are in docs/SOVEREIGN-PROVISIONING.md.
Getting started
Try it (managed)
Visit marketplace.openova.io to install Applications on the openova Sovereign without any infrastructure setup. SaaS journey for SMEs and evaluations.
Run your own Sovereign
1. Provision via catalyst-provisioner.openova.io (managed bootstrap), OR
2. Self-host bp-catalyst-provisioner in your own infrastructure (air-gap path).
Then follow the procedure in docs/SOVEREIGN-PROVISIONING.md.
Build a Blueprint
See docs/BLUEPRINT-AUTHORING.md. A Blueprint is a folder under platform/<name>/ (or products/<name>/) in this monorepo containing blueprint.yaml + manifests (Helm chart or Kustomize base) + (optional) Crossplane Compositions. CI signs each folder's contents and publishes to OCI as ghcr.io/openova-io/bp-<name>:<semver>. Catalyst's blueprint-controller picks it up automatically. Org-private Blueprints follow the same shape inside per-Sovereign Gitea repos.
License
All Blueprints and the Catalyst control plane are open source. Each component carries its own upstream license (typically Apache 2.0, MPL 2.0, or BSD-3); see each component's LICENSE file.
OpenOva charges for support, managed operations, and expert services — never for access to code. See docs/BUSINESS-STRATEGY.md §10.

PRs welcome. The contribution path for Blueprints (including Crossplane Compositions) is documented in docs/BLUEPRINT-AUTHORING.md §13. Issues and discussions on GitHub.
Cloud-native is the foundation. Catalyst is how you operate it.
