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.

# Cleanup Docker Anonymous Volumes
## Description
This Ansible role installs and executes [`dockreap`](https://github.com/kevinveenbirkenbach/docker-volume-cleaner), a tool designed to clean up unused anonymous Docker volumes (including symlinks and their targets) to maintain a tidy Docker environment.
## Overview
The role installs `dockreap` using Python tooling and runs it with the `--no-confirmation` flag to ensure automatic, non-interactive cleanup.
## Cosmos
The diagram places Cleanup Docker Anonymous Volumes 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).
```mermaid
flowchart LR
subgraph role [sys-ctl-cln-anon-volumes 💻]
svc_anon_volumes["anon-volumes"]
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
This role automates the removal of orphaned Docker volumes that consume unnecessary disk space. It is especially useful in backup, CI/CD, or maintenance routines.
## Features
- **Automated Cleanup:** Runs `dockreap --no-confirmation` to remove unused anonymous Docker volumes.
- **Python-based Install:** Installs `dockreap` (isolated, system-friendly CLI install).
- **Idempotent Execution:** Ensures the tool is installed and run only once per playbook run.
- **Symlink-Aware:** Safely handles symlinked `_data` directories and their targets.
