description: The first working version, before any release. Not for production use yet.
changelog:
  category: Preview
---

The first version that syncs the real sources and serves the API. There is no release, image or stable contract
yet: everything here may still change before v1.0.

- **Sync** of the Register of Legal Entities (snapshot and daily files) and six Financial Administration lists,
  with validation thresholds that block a suspicious update instead of publishing it.
- **Search**: one box for a name, IČO, DIČ or IČ DPH, with an adaptive default mode and an optional fuzzy mode.
- **Lookup** by IČO, DIČ or IČ DPH, with <State is="present" />, <State is="absent" /> and
  <State is="unknown" /> per section, as-of dates and content versions; batch lookup for change detection.
- **Self-hosting** with docker compose: separate database roles for migrate, sync and the API.
- **Objections**: a subject can be kept out of name search, with a backup and restore of the list.

Before the first production use, the remaining checks are listed in the project's open questions.
