kevinveenbirkenbachandClaude Opus 4.7 79409ebf10 test(tooling): integrate markdownlint-cli2, ansible-lint, galaxy-importer + fix the resulting baseline
Tooling integration
* add .markdownlint-cli2.jsonc, .ansible-lint, .ansible-lint-ignore
  configs (permissive day-1: cosmetic rules disabled, semantic ones on)
* extend scripts/install/lint.sh with generic install_pip_pkg helper +
  ensure_ansible_lint / ensure_galaxy_importer / ensure_markdownlint_cli2
  ensure_* functions (pip / npm with sudo / --user / --break-system-packages
  fallbacks). install_ansible_tools now also pulls ansible-lint and
  galaxy-importer; new `markdown` install group.
* extend scripts/lint/ansible.sh to run ansible-lint after the existing
  syntax-check.
* add scripts/lint/markdown.sh and scripts/lint/galaxy.sh runners. The
  galaxy runner parallelizes via xargs (-P=$(nproc)), prints OK/FAIL per
  role, and treats `bare-name dependency` errors as success since our
  roles/ tree is not a Galaxy collection layout. All other Galaxy schema
  errors still fail.
* Makefile: new lint-markdown and lint-galaxy targets, both wired into
  `make lint`.
* CI: new workflows lint-markdown.yml and lint-galaxy.yml; lint-ansible.yml
  now installs ansible-core + ansible-lint; ci-orchestrator wires both
  new lint workflows into lint-gate.

Galaxy schema fixes
* shorten the canonical `galaxy_info.company` block from three lines to
  two ("Kevin Veen-Birkenbach\nhttps://www.veen.world", 45 chars) so it
  stays under Galaxy's hard 50-char limit. Updated everywhere: 229 role
  meta/main.yml plus _CANONICAL_COMPANY in
  tests/lint/repository/test_role_meta_main_galaxy_schema.py.
* shorten 19 over-long role descriptions to <=255 chars.
* add stub READMEs for sys-svc-compose-ca and sys-utils-service-loader.

Markdown baseline fixes
* markdownlint-cli2 --fix run repo-wide (formatting normalization
  across CHANGELOG, role READMEs, docs).
* manual MD041 fixes: prepend H1 in 15 files (CHANGELOG, LICENSE,
  TODO.md helpers, role README templates, etc.).
* MD025 / MD003 / MD001 / MD032 manual fixes for heading-style and
  list-spacing edge cases.
* role README content polish: "## Single Point of Truth (SPOT)" headings
  renamed to "## User data resolution" (D3 self-label rule).

Systemd Timer

Description

This role configures a systemd timer to periodically start a corresponding service. It uses a Jinja2 template to create a timer unit file that specifies the scheduling parameters (such as OnCalendar and RandomizedDelaySec) and then restarts the timer service accordingly.

Overview

Optimized for automated task scheduling in a systemd environment, this role:

  • Generates a timer unit file for a given service (using the system_service_timer_service variable).
  • Reloads and restarts the timer using systemd to ensure that changes take effect.
  • Supports dynamic configuration of scheduling parameters via variables like system_service_on_calendar and RANDOMIZED_DELAY_SEC.

Purpose

The primary purpose of this role is to provide a reusable mechanism for scheduling recurring tasks on a system. By creating and managing a systemd timer unit, the role ensures that specified services are automatically started at defined intervals, enhancing system automation and reliability.

Features

  • Dynamic Timer Configuration: Uses a Jinja2 template to create a timer unit file based on provided variables.
  • Automated Service Management: Automatically reloads the systemd daemon and restarts the timer when changes are detected.
  • Flexible Scheduling: Supports configuration of parameters such as OnCalendar and RandomizedDelaySec for precise control over task timing.
  • Persistent Timers: Optionally enables persistent timer behavior to ensure missed activations are handled.
