Backend Validation API
apps/backend/app/api/router/v1/__init__.py, apps/backend/app/api/router/v1/validation.py
Added new validation router with POST /validate endpoint. Defines ValidationRequest (content: str) and ValidationResponse (is_valid, score, issues, sections_found, statistics). Endpoint validates input, calls ResumeValidator, and returns structured response with error handling (400 for empty content, 500 for failures).
Backend Validation Service
apps/backend/app/services/__init__.py, apps/backend/app/services/validation_service.py
Introduced ResumeValidator class with orchestrated validation pipeline. Includes ValidationSeverity enum (error, warning, info), ValidationIssue data structure, and methods for checking content length, critical sections, formatting, keywords, and calculating a 0-100 score. Exposes ResumeValidator via services module.
Frontend Theme System
apps/frontend/components/common/theme-provider.tsx, apps/frontend/components/common/theme-toggle.tsx, apps/frontend/hooks/use-theme.ts
Added theme management system with useTheme hook (persists to localStorage, syncs document class), ThemeProvider context wrapper, and ThemeToggle button component. Supports light/dark modes with Moon/Sun icons.
Frontend Export Utilities
apps/frontend/lib/export-utils.ts, apps/frontend/components/dashboard/export-buttons.tsx
Added AnalysisExportData interface and export functions: exportAsCSV, exportAsJSON, generateHTMLForPDF, and downloadFile. Created ExportButtons component with three outline-styled buttons (CSV, JSON, PDF) for downloading analysis results.
Frontend Tailwind Configuration
apps/frontend/tailwind.config.js
Configured Tailwind dark mode using 'class' strategy and added dark color palette tokens (dark-bg, dark-surface, dark-text).

PR Compliance Guide 🔍

Below is a summary of compliance checks for this PR:

Security Compliance
HTML injection/XSS

Description: The client-side download function creates object URLs and clickable anchors but does not
sanitize the HTML produced by generateHTMLForPDF; if any of the analysis fields contain
untrusted input, the exported HTML could include unsanitized content leading to stored XSS
when opened in a browser.
export-utils.ts [232-241]

Referred Code
export const downloadFile = (content: string, filename: string, mimeType: string) => {
	const blob = new Blob([content], { type: mimeType });
	const url = window.URL.createObjectURL(blob);
	const link = document.createElement('a');
	link.href = url;
	link.download = filename;
	document.body.appendChild(link);
	link.click();
	document.body.removeChild(link);
	window.URL.revokeObjectURL(url);
Weak input validation

Description: The phone number regex is overly permissive and may cause false positives/negatives; while
not a direct exploit, relying on weak validation for contact detection could be abused to
bypass checks—considered a possible weakness rather than a confirmed vulnerability.
validation_service.py [144-146]

Referred Code
has_contact = bool(re.search(r'[\w\.-]+@[\w\.-]+\.\w+', resume_lower)) or \
             bool(re.search(r'\+?1?\s*\(?[\d\s\-\)]{9,}\)?', resume_lower))
Ticket Compliance
🟡
🎫 #534
🟢 Update setup/docs to guide users to resolve "node is not installed" false negatives.
🔴 The setup should correctly detect an existing Node.js installation on Windows when
installed via winget.
🟡
🎫 #535
🔴 Add an advanced SkillsScorer using hybrid Jaccard similarity and semantic similarity
(SentenceTransformer all-MiniLM-L6-v2).
Provide guidance on whether to integrate into Streamlit app or Next.js/FastAPI webapp.
Integrate the module into the chosen part of the project.
🟡
🎫 #438
🔴 Update Pydantic models to allow optional/missing Projects section fields and similar
optional sections.
Preprocess to discard null project entries before validation.
Ensure backend gracefully handles resumes without Projects, avoiding Pydantic validation
errors.
🟢
🎫 #533
🟢 Clarify documentation about missing or renamed files run_first.py and streamlit_app.py.
Update setup docs to reflect current app structure and how to run it without those files.
Codebase Duplication Compliance
Codebase context is not defined

Follow the guide to enable codebase context checks.

Custom Compliance
🟢
Generic: Meaningful Naming and Self-Documenting Code

Objective: Ensure all identifiers clearly express their purpose and intent, making code
self-documenting

🔴
Generic: Secure Error Handling

Objective: To prevent the leakage of sensitive system information through error messages while
providing sufficient detail for internal debugging.

Status:
Verbose Errors: The HTTP 500 response returns internal exception messages to clients which can leak
implementation details; detailed info should be confined to logs and a generic user-facing
message returned.

Referred Code

Generic: Comprehensive Audit Trails

Objective: To create a detailed and reliable record of critical system actions for security analysis
and compliance.

Status:
Missing Auditing: The new validation endpoint performs critical input validation without emitting any
structured audit logs of requests, user context, or outcomes.

Referred Code

Generic: Robust Error Handling and Edge Case Management

Objective: Ensure comprehensive error handling that provides meaningful context and graceful
degradation

Status:
Error Context: The endpoint raises generic HTTP 500 with only exception message and lacks explicit
handling for boundary lengths or validator return-shape validation, which may miss edge
cases.

Referred Code

Generic: Secure Logging Practices

Objective: To ensure logs are useful for debugging and auditing without exposing sensitive
information like PII, PHI, or cardholder data.

Status:
PII In Logs: Logging the raw exception with exc_info during validation may inadvertently include or
correlate with user-provided resume content if exceptions bubble from parsing/validation

Possible issue
Improve phone number validation regex

Improve the phone number validation regex to be more specific and prevent it
from incorrectly matching non-phone number strings like ----------.

apps/backend/app/services/validation_service.py [144-145]

-has_contact = bool(re.search(r'[\w\.-]+@[\w\.-]+\.\w+', resume_lower)) or \
-             bool(re.search(r'\+?1?\s*\(?[\d\s\-\)]{9,}\)?', resume_lower))

+             bool(re.search(phone_regex, resume_lower))
+
  • Apply / Chat
Suggestion importance[1-10]: 7

__

Why: The suggestion correctly identifies a flaw in the phone number regex that could lead to false positives and provides a more robust pattern, improving the validation logic's accuracy.

Medium
Prevent file download race condition

Add a setTimeout before revoking the Blob URL in the downloadFile function to
prevent a race condition that could cause downloads to fail.

apps/frontend/lib/export-utils.ts [232-242]

 export const downloadFile = (content: string, filename: string, mimeType: string) => {
 	const blob = new Blob([content], { type: mimeType });
 	const url = window.URL.createObjectURL(blob);
 	const link = document.createElement('a');
 	link.href = url;
 	link.download = filename;
 	document.body.appendChild(link);
 	link.click();
 	document.body.removeChild(link);
-	window.URL.revokeObjectURL(url);
+	setTimeout(() => window.URL.revokeObjectURL(url), 100);
 };
  • Apply / Chat
Suggestion importance[1-10]: 5

__

Why: The suggestion addresses a potential race condition that could cause downloads to fail in some scenarios and provides a simple fix to improve the reliability of the downloadFile function.

Low
General
Prevent theme-switching flash on load

Prevent a "flash of unstyled content" by moving the theme detection logic from
useEffect to a useState initializer, ensuring the correct theme is set on
initial render.

apps/frontend/hooks/use-theme.ts [15-24]

-useEffect(() => {
-	// Get initial theme from localStorage or system preference
+const [theme, setThemeState] = useState<Theme>(() => {
+	if (typeof window === 'undefined') {
+		return 'light';
+	}
 	const storedTheme = localStorage.getItem('theme') as Theme | null;
 	const prefersDark = window.matchMedia('(prefers-color-scheme: dark)').matches;
-	const initialTheme = storedTheme || (prefersDark ? 'dark' : 'light');
+	return storedTheme || (prefersDark ? 'dark' : 'light');
+});
+const [mounted, setMounted] = useState(false);
 
-	setThemeState(initialTheme);
-	applyTheme(initialTheme);
+useEffect(() => {
+	applyTheme(theme);
 	setMounted(true);
-}, []);
+}, [theme]);
 
+const setTheme = (newTheme: Theme) => {
+...
+

[To ensure code accuracy, apply this suggestion manually]

Suggestion importance[1-10]: 6

__

Why: The suggestion correctly identifies a potential "flash of unstyled content" and proposes a valid pattern to mitigate it, which improves the user experience.

🧹 Nitpick comments (3)
SETUP.md (1)

281-489: Consider condensing the FAQ section.

The FAQ section is comprehensive (200+ lines) but could benefit from better organization. Consider moving some content to separate documentation files (e.g., DEPLOYMENT.md for production questions, API.md for API-specific questions) to improve maintainability and navigation.

apps/frontend/components/common/theme-toggle.tsx (1)

23-23: Consider extracting the lengthy className.

The className string spans multiple Tailwind utilities. For better maintainability, consider using clsx or cn utility, or extracting common button styles into a reusable constant.

Example refactor:

const toggleButtonStyles = "relative inline-flex items-center justify-center rounded-md p-2 text-gray-600 hover:bg-gray-100 hover:text-gray-900 dark:text-gray-400 dark:hover:bg-gray-800 dark:hover:text-gray-100 transition-colors";

<Button
	variant="ghost"
	size="sm"
	onClick={toggleTheme}
	className={toggleButtonStyles}
	aria-label="Toggle theme"
>

14-68: Inject ResumeValidator via FastAPI dependencies.

Per our backend API guidelines we resolve services through Depends(...) instead of constructing them inside the route. That keeps wiring consistent, enables reuse/testing, and lets us extend the validator later without touching every handler. Please add a get_resume_validator() provider and inject it via Depends.

-from fastapi import APIRouter, HTTPException, status
+from fastapi import APIRouter, Depends, HTTPException, status
 ...
-validation_router = APIRouter()
+validation_router = APIRouter()
+
+
+def get_resume_validator() -> ResumeValidator:
+    return ResumeValidator()
 ...
-async def validate_resume(request: ValidationRequest) -> ValidationResponse:
+async def validate_resume(
+    request: ValidationRequest,
+    validator: ResumeValidator = Depends(get_resume_validator),
+) -> ValidationResponse:
 ...
-        validator = ResumeValidator()
-        validation_result = validator.validate(request.content)
+        validation_result = validator.validate(request.content)

⚠️ Potential issue | 🟠 Major

Fix provider to always supply context.

The current implementation returns children without the context provider when !mounted (lines 18-20). This breaks the provider contract: any child component calling useThemeContext() during this phase will receive undefined and trigger the error "must be used within ThemeProvider", even though it technically is within the provider.

While ThemeToggle handles this by checking mounted, other consumers might not be aware of this requirement, leading to runtime errors during hydration.

Apply this diff to always provide context:

 export const ThemeProvider = ({ children }: { children: ReactNode }) => {
 	const { theme, toggleTheme, setTheme, mounted } = useTheme();
 
-	if (!mounted) {
-		return <>{children}</>;
-	}
-
 	return (
 		<ThemeContext.Provider value={{ theme, toggleTheme, setTheme, mounted }}>
 			{children}
 		</ThemeContext.Provider>
 	);
 };

Consumers can still check mounted from the context value if they need to defer rendering, but the context itself will always be available.

ThemeContext.Provider and breaks the provider contract; remove the early return
and always wrap children with <ThemeContext.Provider value={{ theme,

can still read mounted from the context and decide to defer rendering).

⚠️ Potential issue | 🟠 Major

Fix the “PDF” export – it currently downloads HTML.

Clicking the “PDF” button saves ${baseFileName}.html with a text/html MIME type. That’s misleading for users (and the feature promise) because they expect an actual PDF. Either generate a real PDF via a library or relabel the UI as “HTML” until a true PDF exists.

the "PDF" button currently calls a handler that downloads an HTML file (filename
`${baseFileName}.html` with MIME `text/html`), which is misleading. Fix by
either (A) implementing a real PDF generator: replace handleExportPDF to convert
the generated HTML into a PDF (e.g., use html2pdf/html2canvas+jsPDF or
server-side conversion), create an application/pdf Blob and trigger download as
`${baseFileName}.pdf` with MIME `application/pdf`, or (B) immediately relabel
the button to "HTML" (change displayed text, title/aria-label to "Export as
HTML") and keep the existing handler but ensure filename and MIME remain
`.html`/`text/html;charset=utf-8;` so UI matches behavior; choose one approach
and update tests/docs accordingly.

⚠️ Potential issue | 🟠 Major

Guard theme persistence when storage is unavailable.

Safari Private Browsing (and other privacy scopes) throws a DOMException on localStorage.getItem/setItem. Because both the initial effect and setTheme touch storage without a guard, the hook crashes and the UI never toggles. Please wrap the storage access in try/catch and fall back to a safe default so the hook still works when storage is blocked.

effect and setTheme call localStorage.getItem/setItem without guards causing
crashes in environments where storage is unavailable (e.g., Safari Private
Browsing); wrap reads/writes in try/catch: on read, catch and treat storedTheme
as null (fall back to system preference or 'light'), and on write, catch and
ignore errors (no-op) so theme application still proceeds; ensure applyTheme and
state updates run regardless of storage success so the hook remains functional
when storage is blocked.

⚠️ Potential issue | 🟠 Major

Preserve line number 0 in CSV output.

improvement.lineNumber ? … : 'N/A' treats 0 as falsy, so any item pinned to line 0 exports as “N/A”. That’s incorrect data. Please check for null/undefined instead of truthiness.

 		rows.push([
 			`"${improvement.suggestion.replace(/"/g, '""')}"`,
-			improvement.lineNumber ? `Line ${improvement.lineNumber}` : 'N/A',
+			improvement.lineNumber !== undefined && improvement.lineNumber !== null
+				? `Line ${improvement.lineNumber}`
+				: 'N/A',

In apps/frontend/lib/export-utils.ts around lines 34 to 39, the CSV code treats
line 0 as falsy and outputs "N/A"; change the conditional to check for
null/undefined instead of truthiness (e.g., use an explicit != null or typeof
check) so that lineNumber 0 is preserved and only null/undefined become 'N/A'.

(data.details, data.commentary, data.improvements[].suggestion and optional
lineNumber) are interpolated directly into HTML causing XSS; escape all dynamic
strings before embedding by HTML-encoding characters &, <, >, ", ' (and
optionally /) and use the escaped values in the template and the generated
improvementsList; ensure any conditional formatting (like lineNumber) uses the
escaped value and that the final string interpolation only inserts sanitized
text.
