> [!NOTE]
> **Infrapuzzle** is the monorepo for my personal infrastructure, encompassing Kubernetes cluster provisioning, workload deployment, DNS management, and IoT monitoring.

## Repository Structure & Documentation
This repository is divided into distinct domains, each with its own `AGENTS.md` or specialized documentation.

### 1. [Bootstrap](./bootstrap/AGENTS.md) (`bootstrap/`)
*   **Purpose**: Provisioning the single-node Kubernetes cluster (Haumdaucher).
*   **Tool**: Kubespray (Ansible).
*   **Key File**: `init.sh` (Source of Truth for versioning).
*   **Read**: [bootstrap/AGENTS.md](./bootstrap/AGENTS.md)

### 2. [Kubernetes Workloads](./k8s/AGENTS.md) (`k8s/`)
*   **Purpose**: Deploying applications and services to the cluster.
*   **Method**: GitOps-style directory structure (Namespace = Folder).
*   **Constraints**: Enforces `ingress-nginx`, `cert-manager` (Let's Encrypt), and `git-crypt` for secrets.
*   **Read**: [k8s/AGENTS.md](./k8s/AGENTS.md)

### 3. Terraform (`terraform/`)
*   **Purpose**: Infrastructure as Code for external resources, primarily **DNS**.
*   **Provider**: OVH (`ovh/ovh`).
*   **Scope**:
    *   **DNS Zones**: `haumdaucher.de`, `moritzgraf.de`, `ameliegraf.de`, and others.
    *   **Mail Config**: Google Workspace MX/SPF/DKIM records.
    *   **Cluster IP**: Points domains to the Haumdaucher node IP (`136.243.23.215`).
*   **Usage**:
    ```bash
    cd terraform
    terraform init
    terraform apply
    ```

### 4. Monitoring (`monitoring/`)
*   **Purpose**: IoT and physical device monitoring, separate from K8s metrics.
*   **Tool**: [ESPHome](https://esphome.io).
*   **Devices**: Temperature sensors, plant monitors (Xiaomi/BLE), ESP32 bridges.
*   **Usage**:
    ```bash
    cd monitoring
    # Flash or update a device
    esphome run config/<device>.secret.yml
    ```
*   **Network**: Devices typically operate on static IPs in the `192.168.x.x` range.

### 5. Knowledge Wiki & OpenClaw Tasks (`knowledge-wiki/`)
*   **Purpose**: Shared personal knowledge wiki and task dispatch between OpenClaw (mobile/Telegram concierge) and Antigravity (local pair programming agent).
*   **Location**: Git submodule `knowledge-wiki/` at root of `infrapuzzle` (Git repo: `https://git.moritzgraf.de/moritz/knowledge-wiki.git`, branch `main`).
*   **Queue File**: `knowledge-wiki/tasks/antigravity.md`.
*   **Workflow for Antigravity**:
    - When the user asks to check tasks or pick up work from OpenClaw:
      1. Pull latest: `git submodule update --remote knowledge-wiki` (or `git -C knowledge-wiki pull --rebase origin main`)
      2. Read `knowledge-wiki/tasks/antigravity.md` to see pending items.
      3. Implement the chosen task in the appropriate repository files.
      4. Move the task to `## ✅ Completed Tasks` with completion details and commit info.
      5. Push back: `git -C knowledge-wiki commit -am "chore(tasks): complete <task>" && git -C knowledge-wiki push origin main`.
    - When Antigravity needs knowledge about family, home, servers, or setup:
### 6. Architecture Decision Records (`docs/adr/`)
*   **Purpose**: Formal record of architectural decisions, technical trade-offs, and design standards across the monorepo.
*   **Format**: [MADR](https://adr.github.io/madr/) (Markdown Architectural Decision Records).
*   **Consulting ADRs**: AI agents MUST consult `docs/adr/` before designing or altering system architecture, agent topologies, or tool integration patterns.
*   **Key Records**:
    *   [ADR 0001: Hybrid MCP Tool Search and Subagent Delegation for AI Agents](docs/adr/0001-hybrid-mcp-tool-search-and-subagents.md)
    *   [ADR 0002: OpenClaw Multi-Tier Model Selection, Latency Optimization, and Inference Economics](docs/adr/0002-openclaw-model-selection-tiering-and-economics.md)
    *   [ADR 0003: Everything as Code (EaC) and Reproducible Declarative Infrastructure](docs/adr/0003-everything-as-code-and-reproducible-infrastructure.md)

## Global Constraints
*   **Secrets**: `git-crypt` is used extensively. Ensure you have the unlock key before editing `*.secret` files.
*   **Identity**:
    *   **Cluster**: `haumdaucher`
    *   **Primary Domain**: `haumdaucher.de`
    *   **User Identity**: `moritzgraf.de`
