## What’s in this release

- CSV-based node selector (no array validators)
- Cron job callback: `AIXF\AutoArticle\Cron\Convert::run`
- Hardening for nodes that don’t allow articles (schema-aware guard)
- Minimal logging of conversions/skips (can be removed once verified)
- “NoCron” packaging option available if XML importers complain
