 ### Blockers/Concerns
-- Production must run `_rejestracja/sql/apply-2026-04-24-registration-dictionary-phrases.php?run=20260424` or apply the SQL file before dictionary entries are visible/editable.
-- Phase 3 will require applying `_rejestracja/sql/apply-2026-04-24-registration-form-settings.php?run=20260424` or the matching SQL seed after implementation.
+- Production must run `_rejestracja/sql/apply-2026-04-24-registration-dictionary-phrases.php?run=20260424` before dictionary entries are visible/editable.
+- Production must run `_rejestracja/sql/apply-2026-04-24-registration-form-settings.php?run=20260424` before form settings are seeded.
+- Production must run `_rejestracja/sql/apply-2026-04-27-additional-info-field.php?run=20260427` before the "Dodatkowe informacje" field persists.
 
 ### Deferred Issues
