Pull request overview
This PR integrates additional “HF-powered” detector views into the React app and updates navigation/UI scaffolding (header + floating widget manager), alongside a small Render deployment dependency update.
Changes:
- Added routes and lazy-loaded components for multiple new detector views (e.g., traffic sign, abandoned vehicle, water leak, crowd, accessibility).
- Updated Home view UI to surface new “Quick Actions” entries.
- Added new UI components (AppHeader, LoadingSpinner, FloatingButtonsManager) and updated auth client import usage.

There was a problem hiding this comment.
test_home_page is named like a pytest test and sits in a regular Python module, so pytest will likely auto-discover and attempt to run it (requiring a running dev server + Playwright). Consider renaming the function/file (e.g., run_check_home) or placing it under a non-test path/pattern to avoid breaking automated test runs.

This script navigates to http://localhost:5173, but the app’s Home route is now /home (with / used for the landing page). If the intent is to verify the Home UI, update the URL to hit /home to avoid taking a screenshot of the landing page instead.

The newly added detector routes pass onBack={() => navigate('/')}. Since / now renders the Landing page and Home is /home, these “Back to Home” actions will take users to the landing screen instead of the home dashboard. Update these callbacks to navigate to /home (or reuse navigateToView('home')).

useTranslation() is imported and t is destructured but never used, which will trigger unused-variable linting and adds unnecessary bundle/code. Remove the unused useTranslation/t until the header actually renders translated strings.

There was a problem hiding this comment.
FloatingButtonsManager accepts setView but never uses it. This creates dead props and can fail strict lint rules; either remove the prop or actually use it (or rename to _setView) depending on intended future behavior.

There was a problem hiding this comment.
colorClasses is computed but never applied; the code instead hard-codes a comparison to decide text-blue-500 vs text-white. This is brittle and makes variants hard to extend. Prefer mapping variants directly to the final class (e.g., text color) and using a safe fallback when an unknown size/variant is provided.

- Explicitly set `base = "."` to ensure build runs from root context. - Simplified `netlify.toml` by removing potentially conflicting header rules. - Confirmed `publish` directory points to `frontend/dist`. - Verified local build succeeds with `cd frontend && npm install && npm run build`.

In `@backend/requirements-render.txt`:
- Around line 19-20: Update requirements-render.txt to pin the crypto-related
packages: replace the unpinned entries `passlib[bcrypt]` and
`python-jose[cryptography]` with pinned versions (e.g., `passlib>=1.7.4` and
`bcrypt==4.0.1` to ensure bcrypt <5.0.0 compatibility, and `python-jose>=3.4.0`
(preferably 3.5.0) plus `cryptography>=44.0.1`) so that `passlib`, `bcrypt`,
`python-jose`, and `cryptography` are fixed to secure, compatible releases; also
add a note or start a follow-up to add a locked dependency file
(pip-compile/Poetry/Pipenv) to lock transitive dependencies.
In `@frontend/src/AbandonedVehicleDetector.jsx`:
- Around line 1-172: AbandonedVehicleDetector and TrafficSignDetector share
camera, detection loop and canvas overlay logic; extract a reusable LiveDetector
component that contains startCamera, stopCamera, detectFrame, drawDetections,
videoRef and canvasRef, and the useEffect hook, and parameterize it with props:
title, description, detectApi (e.g., detectorsApi.abandonedVehicle),
overlayColor, and onBack; then rewrite AbandonedVehicleDetector and
TrafficSignDetector to be thin wrappers that pass the specific detectApi,
overlayColor and text into LiveDetector, preserving behavior (blob upload,
FormData, canvas sizing and drawing) and ensuring hook dependencies and error
handling remain intact.
- Around line 65-87: The else branch inside detections.forEach currently draws
all no-box labels at fixed coordinates (20,40), causing overlap; modify the loop
to accept the index (e.g., detections.forEach((det, i) => { ... })) and compute
a vertical offset for each label (for example labelY = 40 + i * <spacing>) and
use that y coordinate instead of the hardcoded 40 so each no-box detection
(rendered in the else branch) is drawn on its own line; ensure you update the
fillText/fillRect positions accordingly and keep spacing consistent with text
height.
- Around line 90-121: detectFrame currently draws the video into the overlay
canvasRef (causing doubled visuals) and allows overlapping requests; change it
to draw the video into a separate offscreen canvas (create a local
offscreenCanvas sized to video.videoWidth/video.videoHeight and use its 2D
context to call toBlob) so canvasRef is used only for annotations via
drawDetections, and add an in-flight guard (e.g., a boolean or ref like
inFlightRef/isRequestInFlight checked at the start of detectFrame and set true
before awaiting detectorsApi.abandonedVehicle(formData) and false in finally) to
skip starting a new API call while one is pending; ensure you still resize
offscreenCanvas to the video dimensions and pass the blob from the offscreen
canvas to detectorsApi.abandonedVehicle, and only drawDetections onto
canvasRef's context.
- Around line 10-28: The else branch in the useEffect contains a dead
clearInterval and the detectFrame closure captures a stale isDetecting; change
to store the interval id and detection state in refs (e.g., detectionIntervalRef
and isDetectingRef), update useEffect to set isDetectingRef.current when
isDetecting changes, assign the interval id to detectionIntervalRef.current
inside the if (isDetecting) block and clear it only from the cleanup using
clearInterval(detectionIntervalRef.current), remove the redundant clearInterval
in the else branch, and modify detectFrame to read isDetectingRef.current
instead of the captured isDetecting; keep existing startCamera/stopCamera and
canvasRef clear logic but rely on the cleanup function to clear the interval.
In `@frontend/src/App.jsx`:
- Around line 297-302: The onBack handlers for the detector routes in App.jsx
currently call navigate('/') which sends users to the Landing page; update each
detector route's onBack prop (e.g., WasteDetector, WaterLeakDetector,
CrowdDetector, AccessibilityDetector, TrafficSignDetector,
AbandonedVehicleDetector and also the earlier detectors at lines ~259–296) to
call navigate('/home') instead so the Back button returns to the Home route;
locate the Route elements that pass onBack={() => navigate('/')} and replace the
path string with '/home'.
In `@frontend/src/components/AppHeader.jsx`:
- Line 7: The header element in the AppHeader component currently has
conflicting Tailwind classes ("bg-white" and "bg-white/80"); remove the solid
"bg-white" class from the header's className so the translucent "bg-white/80"
and "backdrop-blur-md" glassmorphism effect can take effect (i.e., update the
header JSX in AppHeader.jsx to drop "bg-white" while keeping "bg-white/80" and
the blur/positioning classes).
In `@frontend/src/components/FloatingButtonsManager.jsx`:
- Around line 4-10: FloatingButtonsManager currently destructures the unused
prop setView and wraps a single child in an unnecessary fragment; either remove
setView from the parameter list and return the single child directly (replace
the fragment with just <ChatWidget />) or, if setView is intended to be used,
pass it through to ChatWidget (e.g., <ChatWidget setView={setView} />) and
implement handling in ChatWidget; update the FloatingButtonsManager declaration
(function params) and its returned JSX accordingly.
In `@verification/check_home.py`:
- Around line 3-20: test_home_page currently only screenshots and prints but
never fails; change it to read the base URL from an environment variable (e.g.,
os.environ.get("BASE_URL", "http://localhost:5173")) instead of the hardcoded
string and add assertions so the test can fail: assert the page loaded
successfully after page.goto (e.g., check response status or wait_for_load_state
and assert page.title() contains expected text) and fail if any console "error"
or pageerror events occurred (collect console/pageerror messages in a list and
assert it is empty). Update references in the function test_home_page
(page.goto, page.on handlers, and the final assertion logic) so the test runner
will correctly surface failures.

9-15:colorClassesmap is never applied — it's used as an indirect string comparison to pick text color.
colorClasses[variant]resolves to a border class string (e.g.,'border-blue-500'), but that string is never added toclassName. Instead, it's compared to'border-blue-500'to decide betweentext-blue-500andtext-white. This is fragile and misleading — if anyone changes the map value, the comparison silently breaks.

passlib bcrypt latest stable version 2025 security advisories
💡 Result:
Latest stable versions (as of 2025)

- bcrypt (pyca/bcrypt on PyPI): 5.0.0 — released Sep 25, 2025. [2]
Security advisories / known issues relevant to 2025
- passlib: No known direct vulnerabilities reported for the latest release 1.7.4 in Snyk’s DB, but older versions (<1.7.3) are flagged for a cryptographic weakness (unsalted SHA-256 “prehash” used with bcrypt, enabling breach-correlation). Upgrade guidance: use passlib ≥ 1.7.3 (1.7.4 satisfies this). [3][4]
- bcrypt (Python package): Snyk and Safety DB report no known direct vulnerabilities affecting bcrypt 5.0.0. [5][6]
Practical 2025 concern (compatibility, not a CVE)
- passlib + bcrypt compatibility: bcrypt releases have explicitly had compatibility friction with passlib (e.g., bcrypt 4.1.0 was yanked due to “incompatibility with assumptions made by passlib”). [2]
- Community reports indicate bcrypt 5.0.0 can break passlib-based workflows (e.g., Ansible users reporting failures and proposing patches, noting passlib maintenance concerns). [7]

This component is nearly identical to TrafficSignDetector.jsx — extract a shared LiveDetector component.
AbandonedVehicleDetector and TrafficSignDetector share ~95% of their code (camera management, detection loop, canvas overlay, UI layout). The only differences are the API endpoint, title, description text, and overlay colors. This is a textbook case for a reusable component parameterized by those differences.

Dead clearInterval in the else branch and stale closure on isDetecting.
On Line 17, interval is always undefined in the else branch because it's only assigned inside if (isDetecting). This clearInterval call is dead code — the cleanup happens correctly in the return function (Line 25).
Additionally, detectFrame (Line 91) checks !isDetecting, but it's captured in a closure where isDetecting was true at the time the interval was created, so this guard never triggers. Consider using a ref to track detection state if you need a reliable guard.
💡 Suggested approach using a ref

let interval;
if (isDetecting) {

Multiple no-box detections render at the same fixed position, overlapping each other.
In the else branch (Line 85), all detections without a bounding box are drawn at coordinates (20, 40), stacking on top of each other. Offset each label vertically using the loop index.

- detections.forEach(det => {
+ detections.forEach((det, index) => {
const { label, confidence, box } = det;
// ...

Drawing video frame onto the overlay canvas causes visual doubling and concurrent request pileup.
Two issues in detectFrame:
-
Visual doubling (Line 104):
context.drawImage(video, ...)paints the video frame ontocanvasRef, which is the transparent overlay canvas positioned on top of the<video>element. This produces a doubled image. The video frame should be drawn to a separate offscreen canvas for blob capture, keepingcanvasRefexclusively for detection annotations. -
No in-flight guard: If the API takes >2s,
setIntervalfires again and queues another request. Multiple overlapping calls can cause flickering detections and unnecessary load. Track whether a request is in-flight and skip if so.
🐛 Proposed fix — use offscreen canvas + in-flight guard
const detectFrame = async () => {
- if (!videoRef.current || !canvasRef.current || !isDetecting) return;
+ if (!videoRef.current || !canvasRef.current) return;
const video = videoRef.current;

In `@frontend/src/AbandonedVehicleDetector.jsx` around lines 90 - 121, detectFrame
currently draws the video into the overlay canvasRef (causing doubled visuals)
and allows overlapping requests; change it to draw the video into a separate
offscreen canvas (create a local offscreenCanvas sized to
video.videoWidth/video.videoHeight and use its 2D context to call toBlob) so
canvasRef is used only for annotations via drawDetections, and add an in-flight
guard (e.g., a boolean or ref like inFlightRef/isRequestInFlight checked at the
start of detectFrame and set true before awaiting
detectorsApi.abandonedVehicle(formData) and false in finally) to skip starting a
new API call while one is pending; ensure you still resize offscreenCanvas to
the video dimensions and pass the blob from the offscreen canvas to
detectorsApi.abandonedVehicle, and only drawDetections onto canvasRef's context.

onBack navigates to / (Landing) instead of /home — broken "Back" button on all new detectors.
The Home route was moved to /home (Line 203), but onBack callbacks here still use navigate('/'), which resolves to the Landing page. Users pressing "Back" from any detector will land on the Landing page instead of Home.
Note: this same issue exists on Lines 259–296 for the pre-existing detectors, but at minimum the newly added routes should be correct.

Conflicting Tailwind background classes: bg-white and bg-white/80.
Both are applied to the same element. bg-white sets full opacity background, which undermines the bg-white/80 + backdrop-blur-md glassmorphism effect you likely intend. Remove bg-white to let the translucent background work with the blur.

setView prop is accepted but never used.
The component destructures setView from props but doesn't use it or pass it to ChatWidget. This indicates incomplete integration. If it's not needed yet, remove it to avoid confusion. Additionally, the fragment wrapper is unnecessary with a single child.

Verification script has no assertions — it will never fail.
test_home_page() captures a screenshot and prints console messages but never asserts anything. If a test runner picks this up (the test_ prefix is pytest-discoverable), it will always pass regardless of page state. Consider adding at least a basic assertion (e.g., checking the page title or that the page loaded without errors).
Also, the hardcoded http://localhost:5173 URL makes this non-portable across environments. Consider using an environment variable.

Security headers were removed — consider restoring them.
The previous configuration included security headers (e.g., X-Frame-Options, X-Content-Type-Options, Content-Security-Policy, etc.) which have been entirely dropped. For an application with authentication and API integrations, these headers are important for defense-in-depth against clickjacking, MIME-sniffing, and XSS.
If the old headers were causing deployment issues, consider adding back at minimum:
