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>

Arduino Development Utilities
Description
This Ansible role installs everything needed for Arduino development on Arch Linux. It includes the official Arduino IDE, documentation, and user group configurations to enable serial port access for uploading code to boards.
Learn more at the Arduino Project Website, Arch Wiki - Arduino, and on Wikipedia.
Overview
Building upon the general developer persona, this role focuses on embedded and microcontroller development. It ensures that the system has the correct packages and permissions to work with Arduino boards via USB.
Cosmos
The diagram places Arduino Development Utilities 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 role enables a ready-to-use Arduino development setup by installing necessary tools and configuring user permissions for serial access.
Features
- Installs Arduino IDE & Docs: Provides GUI and offline references.
- User Group Configuration: Adds the developer to
uucpandlockgroups for serial communication. - Persona Integration: Extends
dev-corewith embedded-specific tools.
