Response Wall Verification Feature - Implementation Summary

✅ COMPLETED - October 16, 2025

Overview

Successfully implemented a comprehensive response verification system for the BNKops Influence Campaign Tool's Response Wall feature. The system allows constituents to submit representative responses with optional email verification, enabling representatives to authenticate submissions.

Features Implemented

1. Postal Code Lookup Integration ✅

Location: Frontend (response-wall.html, response-wall.js, response-wall.css)

Features:

Search by Alberta postal code (T prefix validation)
Fetches representatives from Represent API
Interactive dropdown selection list
Auto-fills form fields when representative selected:
- Representative name
- Title/office position
- Government level (Federal/Provincial/Municipal/School Board)
- Email address (hidden field)
Fallback to manual entry if search fails
Format validation and user-friendly error messages

Implementation Details:

Reuses existing API client (api-client.js)
Validates Canadian postal code format (A1A 1A1)
Government level auto-detection from office type
Responsive UI with clear user feedback

2. Response Verification System ✅

Location: Backend (controllers/responses.js, services/email.js, templates/email/)

Features:

Optional verification checkbox on submission form
Checkbox auto-disabled if no representative email available
Generates cryptographically secure verification tokens
Sends professional HTML/text email to representative

Professional design with gradient backgrounds
Clear call-to-action buttons
Response preview in email body
Campaign and submitter details
Explanation of verification purpose

3. Verification Endpoints ✅

Location: Backend (controllers/responses.js, routes/api.js)

Endpoints:

GET /api/responses/:id/verify/:token - Verify response as authentic
GET /api/responses/:id/report/:token - Report response as invalid

Security Features:

User Flow

Submission Flow with Verification

User opens Response Wall for a campaign
User clicks "Share a Response" button
[NEW] User enters postal code and clicks Search
[NEW] System displays list of representatives
[NEW] User selects their representative
[NEW] Form auto-fills with rep details
User completes response details (type, text, comment, screenshot)
[NEW] User optionally checks "Send verification request"
User submits form
[NEW] System generates verification token (if opted in)
System saves response with pending status
[NEW] System sends verification email (if opted in)
User sees success message

Verification Flow

Representative receives verification email
Representative reviews response content
Representative clicks "Verify This Response"
System validates token
System updates response to verified
System auto-approves response
Representative sees styled success page
Response appears on Response Wall with verified badge

Report Flow

Representative receives verification email
Representative identifies invalid response
Representative clicks "Report as Invalid"
System validates token
System marks response as rejected/disputed
System hides response from public view
Representative sees styled confirmation page
Admin can review disputed responses

Security Implementation

Token Security

Generation: Crypto.randomBytes(32) - 256-bit entropy
Storage: Plain text in database (tokens are one-time use)
Validation: Exact string match required
Expiration: Currently no expiration (recommend 30-day TTL)

Input Validation

Postal Codes: Regex validation for Canadian format
Emails: Email type validation in NocoDB
Response Data: Required field validation
Tokens: URL parameter validation

Rate Limiting

Existing rate limiters apply to submission endpoint
No rate limiting on verification endpoints (public, one-time use)

XSS Prevention

All user inputs escaped before email inclusion
HTML entities encoded in styled pages
Template variable substitution prevents injection

Testing Results

Manual Testing Completed

✅ Postal code search with valid Alberta codes ✅ Validation rejection of non-Alberta codes ✅ Representative dropdown population ✅ Representative selection auto-fill ✅ Verification checkbox disabled without email ✅ Verification checkbox enabled with email ✅ Form submission with verification flag ✅ Backend verification parameter handling ✅ Verification email delivery ✅ Verification link functionality ✅ Report link functionality ✅ Styled HTML page rendering ✅ Token validation ✅ Duplicate verification handling ✅ Invalid token rejection ✅ Manual entry without postal lookup ✅ Modal reset clearing new fields

Integration Testing Required

⚠️ End-to-end flow with real representative email ⚠️ Email deliverability to various providers ⚠️ Mobile responsive testing ⚠️ Browser compatibility (Chrome, Firefox, Safari, Edge) ⚠️ Load testing for concurrent submissions ⚠️ Token collision testing (extremely unlikely but should verify)

Performance Considerations

Frontend

Postal lookup adds one API call per search
Representative list rendering: O(n) where n = representatives count
No significant performance impact expected

Backend

Token generation: Negligible CPU impact
Email sending: Asynchronous, doesn't block response
Database writes: 5 additional columns per response
No new indexes required (token not queried frequently)

Email

Email sending happens after response saved
Failures don't affect submission success
Consider queue system for high-volume deployments

Known Limitations

Postal Code Validation: Only supports Alberta (T prefix)
- Recommendation: Extend to other provinces
Token Expiration: Tokens don't expire
- Recommendation: Implement 30-day expiration
Email Required: Verification requires email address
- Recommendation: Support phone verification for reps without email
No Notification: Submitter not notified when verified
- Recommendation: Add email notification to submitter
Single Verification: Can only verify once per token
- Recommendation: Consider revocation system

Future Enhancements

Short Term (1-3 months)

Token expiration (30 days)
Submitter notification emails
Verification analytics dashboard
Support for other Canadian provinces
Admin verification override

Medium Term (3-6 months)

Representative dashboard for bulk verification
SMS verification option
Response comment system
Verification badge prominence settings
Export verified responses

Long Term (6-12 months)

Full representative portal with authentication
Two-way communication system
Automated verification reminders
Public verification statistics
API for third-party integrations

Rollback Procedures

If Issues Arise

Level 1 - Frontend Only:

git checkout HEAD~1 -- app/public/response-wall.*
docker compose restart

Level 2 - Backend Only:

git checkout HEAD~1 -- app/controllers/responses.js app/services/email.js
docker compose restart

Level 3 - Full Rollback:

git checkout HEAD~1
docker compose build && docker compose up -d

Database Cleanup (optional):

New columns can remain without causing issues
Remove via NocoDB UI if desired

Maintenance Notes

Regular Tasks

Monitor verification email delivery rates
Review disputed responses in admin panel
Check for expired tokens (when expiration implemented)
Monitor token collision (extremely unlikely)

Monitoring Metrics

Verification email success/failure rate
Verification vs. report ratio
Time to verification (submission → verification)
Disputed response resolution time
