E-summit 26 App
A mobile event application with ticket retrieval, QR payloads, and accessibility-related screens.
Problem
An event app brings schedules, ticket access, and participant-facing information into one mobile interface.
Implementation
TicketService queries Firestore, streams tickets by authenticated user, parses a structured QR payload, compares ownership, and marks a ticket as used.
Results
VERIFIED: ticket and QR handling exist, with commits attributed to Zylus08 for ticketing and accessibility work. Attendance, production adoption, and security of deployed rules are unverified.
Limitations
The inspected check-then-update ticket redemption is not a transaction, so concurrent scans need review. Client logic does not substitute for server-side authorization and Firestore rules.
Reproducibility
Reviewed at commit ce3abd9cca8b on 2026-11-09. Source inspection establishes implementation structure; repository-authored results are not independent measurements. The upstream application and benchmark suite were not rerun during this review.
