Review Comment:
**Suggestion:** Unsafe conversion to float:
`float(info.get("completedSplits", 0))` will raise a TypeError if
`info["completedSplits"]` exists but is `None` (float(None) is invalid), and
the progress calculation may divide by zero if `totalSplits` is 0. Coerce None
to numeric defaults using `or` and guard the division to avoid
ZeroDivisionError. [possible bug]
**Severity Level:** Critical 🚨
```suggestion
completed_splits = float(info.get("completedSplits") or 0)
total_splits = float(info.get("totalSplits") or 1)
if total_splits == 0:
progress = 0
else:
progress = math.floor((completed_splits / total_splits) *
100)
```

<summary><b>Why it matters? ⭐ </b></summary>
The existing code can raise TypeError if info['completedSplits'] exists but
is None (float(None)). The suggested change (coerce None to 0 and guard
division) prevents TypeError and explicitly handles total_splits == 0 to avoid
ZeroDivisionError, improving robustness of progress calculation.

Review Comment:
**Suggestion:** Unguarded import of flask_babel: importing `gettext` from
`flask_babel` without a fallback will raise ImportError when `flask_babel` is
not installed and will also use immediate translation (which can require an
app/request context). Wrap the import in a try/except and prefer `lazy_gettext`
when available, with a safe no-op fallback so the module can be imported in
environments where flask_babel is not present and translations won't require a
request context. [possible bug]
**Severity Level:** Critical 🚨
```suggestion
try:
# Prefer lazy_gettext so translations are evaluated lazily (safe outside
request context)
from flask_babel import lazy_gettext as __
except Exception:
# Fallback to a no-op translator if flask_babel isn't available to avoid
import errors
def __(s):
return s
```
<details>
<summary><b>Why it matters? ⭐ </b></summary>
This is a reasonable safety and correctness improvement: using lazy_gettext
avoids evaluating translations at import time (which can require an app/request
context) and wrapping the import prevents ImportError in environments where
flask_babel isn't installed. The change addresses a real risk in how
translations are evaluated and makes the module more robust.
