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. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Cleanup Backups Service
Description
This role automates the cleanup of old backups by executing a Python script that deletes outdated backup versions based on disk usage thresholds. It ensures that backup storage does not exceed a defined usage percentage.
Overview
Optimized for effective disk space management, this role:
- Installs required packages (e.g. lsof and psutil) using pacman.
- Creates a directory for storing cleanup scripts.
- Deploys a Python script that deletes old backup directories when disk usage is too high.
- Configures a systemd service to run the cleanup script, with notifications via sys-ctl-alm-compose.
Cosmos
The diagram places Cleanup Backups Service 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).

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The primary purpose of this role is to maintain optimal backup storage by automatically removing outdated backup versions when disk usage exceeds a specified threshold.
Features
- Automated Cleanup: Executes a Python script to delete old backups.
- Threshold-Based Deletion: Removes backups based on disk usage percentage.
- Systemd Integration: Configures a systemd service to run cleanup tasks.
- Dependency Integration: Works in conjunction with related roles for comprehensive backup management.
