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>

# sys-daemon
|
|
|
|
## Description
|
|
|
|
Role to reset and configure the **systemd manager** for Infinito.Nexus.
|
|
It ensures a clean state of the manager configuration and applies default timeout values.
|
|
|
|
## Overview
|
|
|
|
- Purges the systemd manager drop-in directory if requested.
|
|
- Validates all active unit files before reload/reexec.
|
|
- Applies default timeout values for systemd manager behavior.
|
|
- Provides handler-based reload/reexec for systemd.
|
|
|
|
## Cosmos
|
|
|
|
The diagram places sys-daemon 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 [sys-daemon 💻]
|
|
svc_daemon["daemon"]
|
|
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
|
|
|
|
- **Drop-in Purge:** Optionally remove `/etc/systemd/system.conf.d` contents.
|
|
- **Manager Defaults:** Deploys custom timeouts via `timeouts.conf`.
|
|
- **Validation:** Uses `systemd-analyze verify` before reload.
|
|
- **Integration:** Triggers `daemon-reload` or `daemon-reexec` safely.
