, roshankumar0036singh#754) roshankumar0036singh#753 — free RSVP check-in always failed: checkInParticipant writes checkInStatus/checkedInAt/checkedInBy to events/{eventId}/participants/ {userId}, but the update rule only allowed the participant themselves to touch status/buddyPreference/updatedAt, so the transaction was always denied. - participants update rule: event owner/club may now apply the check-in fields (checkInStatus, checkedInAt, checkedInBy, updatedAt); self-service status updates and the restricted-key checks stay intact - offline sync benefits from the same rule fix (participant update no longer silently swallowed) roshankumar0036singh#754 — offline check-in sync marked attendance on the non-existent events/{eventId}/registrations/{userId} subcollection, so the attended status was silently lost (the catch(() => {}) hid the failure). - syncOfflineCheckInItem now updates the top-level registrations doc registrations/{eventId}_{userId} (the id registerForEvent writes) with status: 'attended' + checkedInAt rules tests: owner check-in field write allowed; non-owner check-in write denied; owner payload rewrite denied; registration attended update allowed for owner, denied for students

Make the registration update required and retryable.
updateDoc() rejects when the registration document is missing. The catch suppresses this error, so the item is counted as synced and removed from the queue. A retry skips the registration update because the check-in document already exists. Move the registration update outside the check-in existence guard and let failures propagate. Add tests for both failure and retry paths.

Implement the stated club authorization policy.
This branch only authorizes isEventOwner() or isEventOwnerAfter(). It never evaluates isClub(). A club account whose UID differs from ownerId is denied participant check-in writes.
Add an event-scoped club authorization condition and a regression test for that actor. Do not grant all club accounts access to every event.

Restrict and test the root registration payload.
The test at Lines 387-403 writes to events/event1/participants/student1. It does not test registrations/event1_student1. Firestore rules Lines 479-482 currently let an event owner change any root registration field, including eventId and userId.
Restrict event-owner registration updates to the intended attendance fields. Add a denied root-registration payload rewrite test. Include checkedInAt in the allowed test because app/src/lib/checkInService.js writes both fields.

Closes #753, Closes #754
Two regressions in the same check-in code path:
#753 — Free RSVP check-in always fails
checkInParticipant(organizer action) writescheckInStatus/checkedInAt/checkedInBytoevents/{eventId}/participants/{userId}, but the participants update rule only allowed the participant themself to touchstatus/buddyPreference/updatedAt— so the check-in transaction was always denied for free RSVP participants.Fix (
firestore.rules): event owner/club may now apply the check-in fields (restricted tocheckInStatus,checkedInAt,checkedInBy,updatedAt). Self-service status updates,validateAttendanceStatus, and the restricted-key checks for everyone else are unchanged. The offline sync participant update (previously swallowed by.catch(() => {})) benefits from the same fix.#754 — Offline sync writes to a non-existent subcollection
syncOfflineCheckInItemupdatedevents/{eventId}/registrations/{userId}— a subcollection that does not exist in the current data model — so theattendedstatus was silently lost.Fix (
checkInService.js): updates the top-levelregistrations/{eventId}_{userId}document (the deterministic idregisterForEventwrites since #735) withstatus: attended+checkedInAt.Tests (
tests/firestore.rules.test.ts)status: attended→ allowedRun:
