448-478: ⚠️ Potential issue

Decorator factory should be synchronous – current signature breaks usage

Declaring async def track_function_performance() forces callers to await the decorator itself, which is not how decorators are normally consumed (@monitor.track_function_performance("foo")).
This will raise TypeError: object NoneType can’t be used in ‘await’ expression or silently leave the coroutine un-awaited.

-    async def track_function_performance(self, func_name: str):
+    def track_function_performance(self, func_name: str):

No other awaits exist in this factory, so making it synchronous is safe.

310-323: 🛠️ Refactor suggestion

stage_requirements_file_path may be referenced before assignment

If the relevant requirements-*.txt file is missing, the variable is never created yet line 322 still reads it, raising UnboundLocalError.

-        stage_requirements_file = None
+        stage_requirements_file_path: str | None = None

and keep using that single variable afterwards.

121-128: NameError risk

Lines 125/144 still instantiate ActionItemExtractor() even though the import is commented out – this will raise NameError. Fix automatically once the main import is restored or guard with HAS_NLTK.

14-16: Remove unused import and redundant datetime re-import

field is not referenced anywhere and Ruff rightfully flags it.
The second from datetime import datetime immediately shadows the first import (line 9) – dead code & noise.

174-210: Consider early-validating placeholder_dir is actually a directory

placeholder_dir.exists() may return True when a file (not dir) with that name already exists, causing mkdir to later fail and the method to silently proceed while every file_path.touch() raises IsADirectoryError.
A quick guard makes the code more resilient:

-if not placeholder_dir.exists():
+if placeholder_dir.exists() and not placeholder_dir.is_dir():
+    logger.error(f"{placeholder_dir} exists and is not a directory.")
+    return False
+if not placeholder_dir.exists():

176-182: Health-check should reflect actual status

Similarly, the health-check now hard-codes "status": "unhealthy" while still trying to propagate fields from the mocked result. Consider returning early with a minimal object to avoid mixed messaging and extra unused keys.

requirements_versions.txt (1)

9-10: Consider bounding the new dependencies to avoid future breaking changes

Blindly accepting any future requests ≥ 2.20 and psutil ≥ 5.8 may bite you when v3.0 (or any ABI-breaking release) lands. Pinning an upper bound (e.g. <3) – or at minimum documenting the expected major series – keeps reproducibility and supply-chain reviews simpler.

-requests>=2.20.0
-psutil>=5.8.0
+requests>=2.20.0,<3.0
+psutil>=5.8.0,<6.0

requirements-dev.txt (1)

7-9: Assess whether uvicorn and fastapi are runtime, not dev, dependencies

If the application’s production entrypoint is FastAPI served by Uvicorn, these belong in requirements_versions.txt (or requirements.txt) so production images/installations pull them in.
Keeping them only in dev requirements risks “works on my machine” surprises during deployment.

Please verify packaging intent and relocate if necessary.

16-18: 👍 Import redirection looks good

The switch to absolute imports matches the refactor of NLP modules; nothing else to flag here.

25-32: Great observability improvement

The extra, highly-specific log lines around NLPEngine import will make extension-loading issues far easier to diagnose. Nice touch.

30-34: Switch to Pattern[...] or ensure Pydantic v2 is enforced

Field(pattern=…) is only valid on Pydantic v2+.
If your runtime still ships v1 (common in many distros), this will raise TypeError: __init__() got an unexpected keyword argument 'pattern'.

Please either:

1. Pin pydantic>=2.0 in requirements*.txt, or
2. Revert to regex= for v1 compatibility.

127-129: validate_by_name replaces allow_population_by_field_name – version check again

Same version-compatibility concern as above. Make sure every consumer environment has Pydantic v2; otherwise parsing will fail.
