- Replace legacy utils/run_once.yml with the new helpers utils/once_flag.yml and utils/once_finalize.yml
- Introduce utils/compose_up.yml to ensure docker-compose stacks are up and to flush handlers safely without coupling to run-once flags
- Migrate all affected roles (desk-*, dev-*, sys-ctl-*, sys-svc-*, web-app-*, web-svc-*, util-*) to the new run-once helpers
- Rework sys-svc-msmtp to auto-load Mailu once per deploy, check reachability, and reuse the running stack instead of requiring multiple playbook passes
- Adjust web-app-mailu to integrate cert deployment, handler flushing, and run-once handling so Mailu is fully initialized in a single deploy
- Improve Matomo, CDN, logout and CSP/health-check related roles to cooperate with the new compose_up / once_* pattern
- Simplify alarm/backup/timer/service orchestration (sys-ctl-alm-*, sys-bkp-provider, sys-timer-cln-bkps, etc.) by moving run-once logic into dedicated 01_core.yml files
- Update integration tests so utils/once_flag.yml and utils/once_finalize.yml are recognised as valid run-once providers, keeping the global run_once_* guarantees consistent
- Align frontend injection and service dependencies so Mastodon- and Mailu-related services can be brought up coherently within a single deployment cycle rather than several iterations
- Improved CSP filter to properly include web-svc-cdn and use protocol-aware domains
- Added Todo.md with redis and OIDC notes
- Enhanced Akaunting role config with CSP flags and redis option
- Updated schema to include app_key validation
- Reworked tasks to handle first-run marker logic cleanly
- Fixed docker-compose template (marker, healthcheck, setup flag)
- Expanded env.j2 with cache, email, proxy, and redis options
- Added javascript.js.j2 template for SSO warning
- Introduced structured vars for Akaunting role
- Removed deprecated update-repository-with-files.yml task
