kevinveenbirkenbachandClaude Opus 5 c55f508e05 feat(readme): draw mandatory and disabled service relations

The cosmos generator linked a consumer to its provider only through an
'<role>' in group_names reference or an explicit provides: name. A hard
dependency has neither -- pinning the provider on unconditionally is
exactly what removes the Jinja reference the generator was reading -- so
web-svc-asset's bond to web-svc-file vanished from the diagram the moment
it became binding. Match a service key against the provider's own primary
key from the registry, in both directions.

Services the role turns off drew a solid 1:1 edge, claiming a mandatory
relationship for something that carries nothing at deploy time. They now
render as a red 0..0 edge; edge merging gained a real precedence so a
provider consumed through two keys stays live when only one is off.

Named colour, not hex: a '#' opens an entity code in the mermaid lexer and
turns the whole diagram into a parse error on GitHub.

Certbot

Description

This Ansible role automates the installation and configuration of Certbot, a free and open-source tool for automating the deployment of Let's Encrypt certificates. It also handles the setup of DNS plugins for ACME challenges.

Overview

Optimized for Archlinux, this role ensures secure SSL/TLS certificate generation with minimal manual intervention. It supports both webroot and DNS-01 validation methods, providing flexibility based on your infrastructure needs.

Key Features

Automatic Installation: Installs certbot and the necessary DNS plugin via pacman.
Dynamic DNS Plugin Support: Automatically installs the correct certbot-dns-<provider> package based on your selected challenge method.
Credential Management: Creates secure credential files for DNS API tokens when using DNS-01 validation.
Idempotent Execution: Tasks are intelligently executed only once per playbook run.

Cosmos

The diagram places Certbot in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

    end

Solid 1:1 edges are fixed relationships; dashed 0..1 edges are conditional (enabled only in matching deployments); red 0..0 edges are turned off in this role. Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in meta/main.yml.

Purpose

The Certbot role provides a ready-to-use, automated solution for SSL/TLS management in your infrastructure. Whether you're managing traditional servers or containerized environments, this role ensures your certificates are always in place and valid.

Features

Certbot Installation: Ensures the latest version of Certbot is installed.
DNS Plugin Installation: Installs a matching plugin based on your configured ACME challenge method.
Credential Directory Management: Creates a secured /etc/certbot directory with proper permissions.
API Token File Setup: Manages API token files securely for DNS challenge authentication.
