If the transcription API returns an empty string (e.g., no speech detected or transcription failed silently), the user receives no feedback. The button will stop processing and return to the normal state, but the user won't know if the recording was successful or if nothing was transcribed. Consider providing user feedback when the transcription returns an empty result, such as "No speech detected" or "Unable to transcribe audio".

There was a problem hiding this comment.
The stopRecording function doesn't check the MediaRecorder's state before calling stop(). If the recorder is already stopped or in an inactive state, calling stop() will throw an error. Consider checking mediaRecorderRef.current.state === 'recording' before calling stop() to prevent potential errors.

The stream variable is captured in the closure of the onstop handler on line 24, but if the user clicks the recording button multiple times without completing a recording, the stream reference will point to an old stream object. This could lead to improper cleanup of media resources.
Consider storing the stream in a ref (e.g., streamRef.current) and accessing it from there in the onstop handler. Additionally, clean up any existing stream before starting a new recording.

The language parameter is accepted but never used in the new implementation. OpenAI Whisper can accept a language hint for better transcription accuracy. Consider either removing the parameter if it's not needed, or passing it to the backend endpoint to be used with the Whisper API.

Unlike the /api/detect-audio endpoint which checks the size of audio_bytes after reading (line 1398), this endpoint only checks file.size before reading. If file.size is not available (e.g., for some upload types), the size check could be bypassed. Consider adding a size check on the audio_bytes after reading, similar to the pattern used in the detect-audio endpoint.

The component doesn't clean up media resources on unmount. If the user navigates away or the component unmounts while recording is in progress, the microphone will remain active and the stream won't be stopped. Consider adding a useEffect cleanup function that stops any active recording and releases the media stream when the component unmounts.

Propagate transcription failures instead of returning empty text.
On non‑200 or exceptions, returning "" makes the endpoint respond 200 with an empty transcript, so the UI can’t distinguish silence from failure. Prefer raising (or returning explicit error details) so callers can surface a real error.
🔧 Proposed fix (propagate failures)
- if response.status_code == 200:
- # Result is usually {"text": "..."}
- data = response.json()
- return data.get("text", "")

Enforce size limit based on actual bytes, not just file.size.
UploadFile.size can be unset, so large uploads can bypass the 25MB gate. Add a post‑read length check (and optionally reject empty audio) to prevent oversized uploads from slipping through.

Add "Vandalism" category to backend enum and update smart-scan mapping.
The backend IssueCategory enum in backend/schemas.py does not include "Vandalism"—only Road, Water, Streetlight, Garbage, College Infra, and Women Safety. Users selecting the new "Vandalism / Graffiti" option will receive a 400 error on submission.
Additionally, the mapSmartScanToCategory function currently maps 'graffiti vandalism' to 'college_infra', so smart-scan won't suggest the new category once it's added.

In `@frontend/src/SmartScanner.jsx`:
- Around line 139-152: The effect's interval callback uses stale closures for
detectFrame, model and previousFrame causing silent failures; change detectFrame
to read model and previousFrame from refs (e.g., modelRef and previousFrameRef
updated inside setModel/setPreviousFrame) or memoize
startCamera/stopCamera/detectFrame with useCallback and include them in the
effect deps so the interval always sees fresh references; ensure you clear the
interval only where it can be defined (remove the dead else branch check for
interval) and update the effect to set interval on start and clear it in the
cleanup using the stable refs/callbacks (refer to useEffect, detectFrame, model,
previousFrame, setPreviousFrame, startCamera, stopCamera).
In `@frontend/src/views/GrievanceView.jsx`:
- Line 4: The parent call to the GrievanceView component still passes a setView
prop even though the GrievanceView component signature no longer accepts it;
open the parent component that renders <GrievanceView /> (in App.jsx) and remove
the prop assignment setView={navigateToView} from the JSX invocation so the
component is rendered without that unused prop; also scan for any leftover
references to setView in that parent render block to avoid unused variable
warnings.
In `@frontend/src/WaterLeakDetector.jsx`:
- Around line 101-118: The effect creates a timer that is only assigned when
isDetecting is true, so clearInterval in the else branch is redundant and you
should avoid suppressing lint; fix by storing the interval id in a ref (e.g.,
detectionIntervalRef) and always use that ref to set/clear the interval in both
the if branch and cleanup, remove the else clearInterval, and wrap startCamera
and detectFrame in useCallback so you can include them in the useEffect
dependency array (use detectionIntervalRef, startCamera, detectFrame,
stopCamera, and canvasRef as dependencies) to eliminate the eslint-disable and
prevent stale closures.
🧹 Nitpick comments (5)
frontend/src/views/GrievanceView.jsx (1)
37-40: Consider usinguseCallbackinstead of disabling the exhaustive-deps rule.The ESLint disable comment suppresses a legitimate warning. Since
loadDatais recreated on every render and capturesfiltersvia closure, it's safer to either wraploadDatainuseCallbackor inline the fetch logic directly in the effect.♻️ Recommended: Wrap loadData with useCallback

34-48: Consider usingdetectorsApi.streetLightfor consistency.This component uses raw
fetch()while other detectors (e.g.,VandalismDetector) use thedetectorsApiabstraction. ThedetectorsApi.streetLightmethod already exists infrontend/src/api/detectors.js(line 45).♻️ Suggested refactor for consistency
+import { detectorsApi } from './api/detectors'; ... - const response = await fetch('/api/detect-street-light', { - method: 'POST', - body: formData, - }); - - if (response.ok) { - const data = await response.json(); + const data = await detectorsApi.streetLight(formData); + if (data) { setDetections(data.detections); if (data.detections.length === 0) { alert("No broken street lights detected."); } - } else { - console.error("Detection failed"); - alert("Detection failed. Please try again."); }frontend/src/api/detectors.js (1)
4-32: Clean up verbose inline comments and simplify logic.The extensive comments (lines 5-30) document a thought process but clutter production code. Additionally, the
FormDatacheck on line 6 is redundant since both branches callpostFormanyway.♻️ Simplified implementation

12-39: Consider adding a timeout or max recording duration.There's no limit on how long a user can record. Very long recordings could result in large uploads and potential API timeouts. Consider adding a maximum duration safeguard.

Remove setView prop from <GrievanceView /> usage in parent component.
The component signature no longer accepts the setView prop, but the parent component in frontend/src/App.jsx (lines 208-210) still passes setView={navigateToView}. Since the component doesn't use this prop, remove it from the parent call for clarity.

In `@frontend/src/views/GrievanceView.jsx` at line 4, The parent call to the
GrievanceView component still passes a setView prop even though the
GrievanceView component signature no longer accepts it; open the parent
component that renders <GrievanceView /> (in App.jsx) and remove the prop
assignment setView={navigateToView} from the JSX invocation so the component is
rendered without that unused prop; also scan for any leftover references to
setView in that parent render block to avoid unused variable warnings.

There was a problem hiding this comment.
Redundant clearInterval in else branch; consider addressing suppressed lint warnings.
On line 108, clearInterval(interval) in the else branch is ineffective because interval is only assigned in the if branch (line 105), so it's always undefined here. The eslint-disable comments suppress warnings about missing dependencies (startCamera, detectFrame), which could lead to stale closures.
🔧 Remove redundant clearInterval
} else {
stopCamera();
- if (interval) clearInterval(interval);
if (canvasRef.current) {
const ctx = canvasRef.current.getContext('2d');
ctx.clearRect(0, 0, canvasRef.current.width, canvasRef.current.height);
}
}For a more robust solution, consider wrapping startCamera and detectFrame in useCallback to properly include them in the dependency array without suppressing the lint rule.

In `@frontend/src/WaterLeakDetector.jsx` around lines 101 - 118, The effect
creates a timer that is only assigned when isDetecting is true, so clearInterval
in the else branch is redundant and you should avoid suppressing lint; fix by
storing the interval id in a ref (e.g., detectionIntervalRef) and always use
that ref to set/clear the interval in both the if branch and cleanup, remove the
else clearInterval, and wrap startCamera and detectFrame in useCallback so you
can include them in the useEffect dependency array (use detectionIntervalRef,
startCamera, detectFrame, stopCamera, and canvasRef as dependencies) to
eliminate the eslint-disable and prevent stale closures.
- Reordered functions in `WaterLeakDetector.jsx` and `SmartScanner.jsx` to ensure they are defined before use in `useEffect`, resolving "variable used before declaration" lint errors. - Fixed `no-unused-vars` lint errors in multiple detectors by ignoring the `err` variable in catch blocks. - Fixed `GrievanceView.jsx` `useEffect` dependency warning. - Cleared `node_modules` and rebuilt frontend to ensure clean state. - Verified build and lint (file-level) pass locally.
