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.

sys-ctl-hlth-btrfs

Description

Checks the health of all mounted Btrfs filesystems by inspecting device error counters.

Overview

This role health-check for Btrfs filesystems, alerts on any device error counters.

Cosmos

The diagram places sys-ctl-hlth-btrfs 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).

flowchart LR
    subgraph role [sys-ctl-hlth-btrfs 💻]
        svc_btrfs["btrfs"]
    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.

Features

Iterates over every Btrfs filesystem.
Runs btrfs device stats and alerts if any error counters are non-zero.
Hooks into systemd and a timer for regular checks.
On failure, calls sys-ctl-alm-compose.infinito@… for notification.

Usage

Just include this role in your playbook; it will:

Deploy a small shell script
Install a .service and .timer unit.
Send alerts via sys-ctl-alm-compose if any filesystem shows errors.
