Description

Backend service that processes event sign-up requests from peer mentors and contacts. Validates eligibility against role-based access rules, enforces configured capacity limits, and persists participant records consumed by attendance, statistics, and Bufdir reporting features.

Feature: Event Sign-up

event-registration-service

Sources & reasoning

Event Sign-up is the third canonical feature of the event-management area in section 8 and is implied by the core operational flow (peer mentor performs activity or event). Marked MVP because the operational flow described as Phase 1 requires events to be participable, not just creatable and listable.

  • event-management | Event Management | Event Creation, Event Listing, Event Sign-up
  • Optimistic mutations with automatic rollback on failure (contact edits and paginated list updates)
  • Peer mentor performs activity or event ... Activity is registered and tracked in Meander Mobile App ... Coordinator oversees follow-up, quality, and approval

Responsibilities

  • Validate user eligibility for the event based on role and access rules
  • Enforce event capacity limits with concurrency-safe checks
  • Create and persist participant records linking user to event
  • Emit registration events for downstream attendance and reporting consumers
  • Return structured registration outcomes (success, full, ineligible, duplicate)
