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.

# Shell
## Description
This Ansible role ensures that [.profile](https://en.wikipedia.org/wiki/Bourne_shell#Startup_scripts) is sourced in both [Bash](https://www.gnu.org/software/bash/) and [Zsh](https://www.zsh.org/) environments. It enables consistent environment variable loading across different login shells by linking shell-specific profile files (`.bash_profile`, `.zprofile`) to a centralized `.profile`.
## Overview
By standardizing `.profile` as the central source for environment configuration, this role ensures consistent shell behavior. It does **not** manage the contents of `.profile` itself; it only guarantees that it is sourced by supported shells.
## Cosmos
The diagram places Shell 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

subgraph role [dev-shell 💻]
svc_shell["shell"]
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 purpose of this role is to unify shell environment setup across Bash and Zsh. It minimizes duplication and confusion by encouraging the use of `.profile` for shared configuration such as environment variables and agent settings.
## Features
- **Centralized Configuration:** Promotes `.profile` as the single source for shared shell settings.
- **Cross-Shell Compatibility:** Ensures both Bash and Zsh source `.profile` properly.
- **Non-Invasive:** Does not alter the content of `.profile`.
