 ### Changed
+- ČSFD country tag category renamed **Země → Země původu**. Added
+  `scripts/migrate_tag_category.py` to rewrite the category in an existing pool
+  index (backs up `.Curator.!index` first); run against the live pool.
+- Filmotéka tree now also builds the **Země původu** branch — it was missing
+  from `FILMOTEKA_CATEGORIES`, so the country level was never generated. Tree
+  categories are now Rok / Žánr / Země původu / Hodnocení.
+- Movie table trimmed to **Název / Štítky / Velikost** — the Datum and ČSFD
+  columns were dropped (a ČSFD link is a prerequisite, so its indicator was
+  always the same).
 - All references to "Tagger" renamed to "Curator" (code, spec, config filenames
   `.Curator.!gtag` / `.Curator.!ftag`, tests).
 - `requires-python` narrowed to `>=3.14,<3.15` (PySide6 compatibility).
 
+### Removed
+- Legacy Tagger predefined tags: the always-available **Hodnocení** (⭐ rating)
+  and **Barva** (color) categories in `TagManager`, and the automatic
+  **Stav/Nové** tag assigned to every newly imported file. `DEFAULT_TAGS` is now
