fix(security): stop exposing attendee IPs and rejected presentations on the public API - #673
Two data leaks on the public API, both reproducible logged out:
/summits/{id}/events/published?expand=current_attendance returned attendance records with ip, browser, origin and attendee data.
current_attendance is now serialized with a dedicated PublicSummitEventAttendanceMetricSerializer that omits ip, browser, origin and created_by_id.
SummitEventAttendanceMetric stays mapped to the full serializer for PUBLIC, PRIVATE and the default type (metrics enter/leave unchanged). Only the new PUBLIC_ATTENDANCE type, selected by SummitEventSerializer for that relation, uses the public one. AdminSummitEventSerializer still resolves every relation as PRIVATE.
Admin serializers that don't override getSerializerType() opt out through a new canExposeAttendanceTechnicalData() hook: AdminSummitEventWithFileSerializer (and its CSV subclass) and AdminSummitEventCSVSerializer keep the full attendance metrics.
SummitGroupEvent used the same serializer for PUBLIC, PRIVATE and CSV; a new AdminSummitGroupEventSerializer now handles PRIVATE and CSV, so admins keep ip/browser/origin on group events too.
/summits/{id}/speakers?expand=rejected_presentations returned rejected submissions in full (title, abstract, selection status, extra-question answers).
PresentationSpeakerSerializer (public) no longer returns rejected_presentations, neither as ids nor expanded.
The same applies to the other unpublished submissions: alternate_presentations is hidden in the public serializer, and accepted_presentations only returns published ones (new optional $published_only argument on PresentationSpeaker::getAcceptedPresentations() / getAcceptedPresentationIds(), default false, so other callers are unchanged).
AdminPresentationSpeakerSerializer overrides the canExpose* hooks, so admins and the speaker's own profile (which resolves to the admin serializer) keep the current output.
Notes
Name, picture (honoring the profile privacy flags) and attendee_id are still returned for attendance; the ticket only asks to remove ip/browser/origin.
Behavior change for non-admin clients: alternate_presentations is no longer returned and unpublished accepted presentations are filtered out.
Public responses are cached (cache_api_response, ~10 min), so the old payload may be served for that long after deploy.
Test plan
PublicSummitEventAttendanceMetricSerializerTest: public serializer omits sensitive fields; registry keeps the full serializer for private/default; public event serializers select PUBLIC_ATTENDANCE while every admin/CSV event serializer (event, event with file, group event) keeps the full one; registry maps AdminSummitGroupEventSerializer for private/CSV.
PresentationSpeakerRejectedPresentationsTest: public serializer omits rejected and alternate presentations and asks only for published accepted ones; admin serializer keeps all of them.
SpeakerRepositoryTest and OAuth2SummitSpeakersApiTest (108 tests) pass with the modified accepted-presentations query.
Existing AdminPresentationSpeakerSerializerTest still passes.
Public event attendance details no longer include technical information such as IP addresses and browser data. Member photo and name visibility preferences are respected.
Public speaker profiles no longer show rejected or alternate presentations, or accepted presentations that have not been published. Admin views continue to include these presentations.
…nd=current_attendance on the public API
Serialize the current_attendance collection of the public SummitEvent
serializer with a dedicated public serializer that omits ip, browser,
origin and created_by_id. The admin serializer keeps the full one.
Public event attendance uses a serializer that applies member visibility settings. Speaker serializers now control exposure of rejected, alternate, and unpublished accepted presentations, with separate policies for public and admin serialization.

Select and serialize public attendance metrics app/ModelSerializers/SerializerRegistry.php, app/ModelSerializers/Summit/SummitEventSerializer.php, app/ModelSerializers/Summit/Metrics/PublicSummitEventAttendanceMetricSerializer.php, tests/PublicSummitEventAttendanceMetricSerializerTest.php
The current_attendance relation selects a public-specific serializer. That serializer maps attendance fields and applies member photo and name visibility settings. Tests check sensitive-field omission and serializer selection.

Summary
Filter presentation data by serializer policy app/Models/Foundation/Summit/Speakers/PresentationSpeaker.php, app/ModelSerializers/Summit/Speakers/PresentationSpeakerSerializer.php, app/ModelSerializers/Summit/Speakers/AdminPresentationSpeakerSerializer.php, tests/PresentationSpeakerRejectedPresentationsTest.php
Accepted-presentation lookups can filter for published presentations. The public serializer hides rejected and alternate presentations and excludes unpublished accepted presentations. The admin serializer enables those exposures. Tests check the public and admin policies.
The change restricts public exposure of attendee technical data and of rejected, alternate and unpublished presentations while keeping the admin output. No concrete merge-blocking risk was found; the remaining suggestions concern test coverage.

…ed_presentations on the public speakers API
The public PresentationSpeakerSerializer no longer returns rejected_presentations,
neither as ids nor expanded. AdminPresentationSpeakerSerializer (admins and the
speaker's own profile) opts back in, so the private output is unchanged.

…from the public speakers API

Add a regression test for event-level attendance expansion.
These tests exercise the public metric serializer and registry separately. They do not exercise SummitEventSerializer selecting the serializer for current_attendance. Removing that selection would leave these assertions unchanged. (raw.githubusercontent.com)
Serialize an event with expand=current_attendance through the registry. Assert that the public result omits the four sensitive fields. Add an admin case that verifies the full attendance output remains available.

Test publication filtering with real presentations.
This stub makes both expanded accepted-presentation queries return empty arrays. The flag assertions cover only the ID calls, and the test does not exercise the new query predicate. Add coverage with published and unpublished presentations for both speaker and moderator roles.

… and group event serializers
SummitEventSerializer selected PUBLIC_ATTENDANCE for current_attendance in every
subclass without its own getSerializerType(), so admins lost ip, browser and
origin on SummitEventWithFile and SummitGroupEvent events. Add a
canExposeAttendanceTechnicalData() hook, enable it on the admin and CSV event
serializers, and add AdminSummitGroupEventSerializer for the PRIVATE and CSV
group event types.
