+            checks.append(has_cyprus)
+
+            conn.close()
+        except Exception as e:


The broad exception handler catches all exceptions including system-level exceptions like KeyboardInterrupt and SystemExit. Consider catching specific exceptions (e.g., sqlite3.Error, sqlite3.DatabaseError) or at least avoid catching BaseException subclasses that should propagate.

Suggested change

except Exception as e:

except sqlite3.Error as e:

verify_extraction.py

+        exists = os.path.isfile(path)
+        size = os.path.getsize(path) / (1024*1024) if exists else 0


If a file doesn't exist, calling os.path.getsize() will raise FileNotFoundError. The ternary operator checks 'exists' but this could fail if the file is deleted between the exists check and getsize call. Consider moving the size calculation inside an if block or catching the specific exception.

Suggested change

exists = os.path.isfile(path)

size = os.path.getsize(path) / (1024*1024) if exists else 0

try:

size_bytes = os.path.getsize(path)

exists = True

size = size_bytes / (1024*1024)

except FileNotFoundError:

exists = False

size = 0

+            case_count = cursor.fetchone()[0]
+            valid_cases = case_count > 15000


The magic number 15000 for validating case count is not explained. Consider defining this as a named constant (e.g., MINIMUM_EXPECTED_CASES = 15000) with a comment explaining why this threshold was chosen, to improve code maintainability.

+            checks.append(has_cyprus)
+
+            conn.close()


The database connection is not properly closed if an exception occurs before line 55. Consider using a context manager (with statement) to ensure the connection is always closed: with sqlite3.connect(db_path) as conn:

Suggested change

conn = sqlite3.connect(db_path)

cursor = conn.cursor()

cursor.execute("SELECT COUNT(*) FROM `case`")

case_count = cursor.fetchone()[0]

valid_cases = case_count > 15000

print(f" {check_mark(valid_cases)} Cases count: {case_count:,}")

checks.append(valid_cases)

cursor.execute("SELECT COUNT(*) FROM `case` WHERE respondent='CYP'")

cyprus_count = cursor.fetchone()[0]

has_cyprus = cyprus_count > 0

print(f" {check_mark(has_cyprus)} Cyprus cases: {cyprus_count}")

checks.append(has_cyprus)

conn.close()

with sqlite3.connect(db_path) as conn:

The verify_extraction.py script lacks test coverage. Given that the repository has comprehensive automated testing for Python code (tests/ directory with pytest configuration), consider adding tests for this verification script to ensure its reliability. Tests should cover scenarios like: missing directories, corrupted database, invalid file paths, and import failures.

+        kw = get_keywords_by_article("6")
+        has_keywords = len(kw) > 0
+        print(f"   ✅ hudoc_keywords module imported ({len(kw)} keywords)")


The variable name 'kw' is too abbreviated and unclear. Consider using a more descriptive name like 'keywords' to improve code readability.

Suggested change

kw = get_keywords_by_article("6")

has_keywords = len(kw) > 0

print(f" ✅ hudoc_keywords module imported ({len(kw)} keywords)")

keywords = get_keywords_by_article("6")

has_keywords = len(keywords) > 0

print(f" ✅ hudoc_keywords module imported ({len(keywords)} keywords)")

Modifying sys.path at runtime can lead to unexpected import behavior and namespace conflicts. Consider using a more robust approach such as proper package installation, relative imports, or setting PYTHONPATH environment variable before running the script.
