Summary

Follow-up to #624. #624 refuses every delete of a sponsor extra question or answer option, because a device can hold answers the server has not seen. That is the right rule for sponsors, but without an escape hatch a stuck sponsor ends with someone deleting the question straight in the database: no checks, no record, no undo.

An FN admin who has the sponsor's devices in hand and can see there are no pending uploads can confirm a delete is safe. This gives admins a guarded and audited way to do it. Sponsors can never delete.

What changes

DELETE .../extra-questions/{extra_question_id} and DELETE .../extra-questions/{extra_question_id}/values/{value_id}, rules in order:

  1. Without force=true: refused (412) for everyone, as in fix(sponsors): never reject badge scan uploads over mandatory questions and block deleting extra questions #624.
  2. force=true from a non-admin: 403. The flag never helps a sponsor.
  3. force=true from an admin: a non-empty reason is required, otherwise 412.
  4. Collected answers on the server: 0 deletes; more than 0 is refused (412) with their count unless delete_answers=true.
  5. Every force delete is audited (who, summit, sponsor, question or option, reason, answers deleted and modified).
  6. A force deleted question frees its slot under Sponsor::MaxExtraQuestionCount right away.

Two new admin-only endpoints, the pre-check the admin reads before deleting:
GET .../extra-questions/{id}/usage and GET .../values/{value_id}/usage. They return the answers a force delete would affect and the sponsor's scan activity per rep (scans and last scan). They do not prove devices have nothing pending, only the devices can show that.

Decisions

  • Admin means Member::isAdmin() (Super Admins, Administrators) or isSummitAdmin() allowed on that summit, the same rule as isAuthzFor minus the sponsor membership. The controller decides and passes the admin to the service as force_by; the service refuses when there is none.
  • Option deletes, only the option leaves. An answer value is a comma separated list of option ids ("12,15,19"). Deleting an option deletes an answer only when it was its only selection; otherwise the id is taken out of the list ("12,19"). Deleting whole answers would also destroy selections of other options that still exist. The error message and usage split both numbers (answers_to_delete, answers_to_modify) and the audit records both.
  • Ids are matched one by one, never with a substring or LIKE: 15 would match 115, and a legacy free text answer like 15 apples would match 15 (a Text question switched to a list type keeps its free text answers).
  • Deleting a question destroys its collected answers first. ExtraQuestionAnswer.QuestionID references the question with no ON DELETE CASCADE, so the answers go before the question. They are removed through their badge scan (orphan removal) and the scan's last edited date is touched; the scans are kept.
  • reason and delete_answers are read from the JSON body or the query string. The body is what the ticket specifies, but some clients and proxies drop the body of a DELETE, so the query string works too.
  • The usage endpoints are admin only (403 otherwise). The ticket does not say; they list the sponsor's reps with their emails and they only inform a force delete, so they follow the same rule.
  • Not found: the force path returns 404 for an unknown sponsor, question or option. The path without force does not look anything up, so for a non-admin it never reveals whether an id exists (same as fix(sponsors): never reject badge scan uploads over mandatory questions and block deleting extra questions #624).
  • The audit entry is emitted explicitly. The onFlush listener already audits the deleted entities, but its formatters only get the entity and the change set, so it cannot carry the reason nor the counts. It is always written to the application log and also sent through OTLP when opentelemetry.enabled. The listener returns early in the testing environment, so the tests capture the emitted job instead.
  • Cap: nothing extra, deleting the question already frees the slot; covered by a test that adds a question to a sponsor that was at 5.

Deploy

A config migration has to run with this release (Version20261009130000): it registers the two usage routes in api_endpoints. The seeder only covers fresh installs and OAuth2BearerAccessTokenRequestValidator rejects any route missing from api_endpoints with a 400 before the controller runs. The DELETE routes were already registered.
Route cache: the cached routes have to be regenerated (php artisan route:cache).

Tests

  • New OAuth2SummitSponsorExtraQuestionForceDeleteApiTest (13 tests, admin): plain delete refused, missing reason, unknown id, delete with 0 answers (slot freed, audit emitted), refused with the answers count, confirmed delete of answers (scans kept), the same for options including the delete-or-strip split, and both usage endpoints.
  • 3 new tests in OAuth2SummitSponsorApiTest with a sponsor-only user: a plain delete is refused (412, proving the sponsor is authorized) and force=true gets 403, for questions and options, and usage is forbidden. The test token stub grants everybody the administrators group and the first request syncs it into the member, so these tests swap the stub before the first request.
  • OAuth2SummitSponsorExtraQuestionForceDeleteApiTest, OAuth2SummitSponsorApiTest and OAuth2SummitBadgeScanApiControllerTest: 108 tests pass. The full suite was not run.

Not covered

  • The path of a summit admin that is not a global admin (isSummitAdmin() plus summit permission) is not exercised; the tests use Administrators.
  • A client with no user (client credentials) is not verified: the existing isAuthzFor call on a null current user comes first and predates this change.
  • The OpenAPI annotations of the four endpoints are written but the docs were not regenerated to validate them.

The UI (Force delete action with the checklist, reason and second confirmation) is in summit-admin, in a separate PR.

Summary by CodeRabbit

  • New Features
    • Authorized summit administrators can force-delete sponsor extra questions and answer options, with a reason and confirmation when collected answers will be affected.
    • New usage views show affected answer counts and sponsor badge-scan activity before deletion.
    • Deletion reports how answers were removed or updated, while preserving badge scans.

…d answer options

Follow-up to #624, which refuses every delete because devices may hold answers
the server has not seen. Without an escape hatch the question ends up deleted
straight in the database, with no checks, no record and no undo. An admin who
has checked the devices can confirm a delete is safe, so give admins a guarded
and audited way to do it. Sponsors still can never delete.

DELETE .../extra-questions/{id} and .../values/{value_id}:
- without force=true: refused (412) for everyone, as in #624
- force=true from a non-admin: 403. Admin is isAdmin(), or isSummitAdmin() allowed on the summit
- force=true from an admin: a non-empty reason is required (412)
- collected answers: refused with their count unless delete_answers=true
- a force deleted question frees its slot under the 5 questions cap

Deleting a question destroys its collected answers first (the answer table
references it without cascade); the scans are kept. Deleting an option deletes
an answer only when it was its only selection, otherwise the option id is taken
out of the answer's list. The ids are matched one by one: the answer value is a
comma separated list, so a substring match would take 15 for 115.

GET .../extra-questions/{id}/usage and .../values/{value_id}/usage (admin only)
return the answers a force delete would affect and the sponsor's scan activity
per rep. Registered by a config migration plus the seeder, the validator rejects
routes missing from api_endpoints.

Every force delete leaves an audit entry with who, summit, sponsor, the question
or option, the reason and the answers deleted or modified. The onFlush listener
cannot carry the reason nor the counts, so it is emitted explicitly.

📝 Walkthrough

Walkthrough

Sponsor extra-question and answer-option deletion now supports an authorized force-delete path with a reason and answer-change confirmation. The change also adds audit logging, usage endpoints, repository queries for answers and scan activity, endpoint registrations, and API tests.

Changes

Sponsor extra-question force deletion

Layer / File(s) Summary
Usage contracts and data access
app/Services/Model/ISummitSponsorService.php, app/Models/Foundation/Summit/Repositories/*, app/Repositories/Summit/DoctrineSponsor*Repository.php
Service and repository contracts add usage-reporting methods. Repository implementations retrieve answers by question and per-member sponsor scan activity.
Deletion behavior and audit
app/Services/Model/Imp/SummitSponsorService.php, app/Audit/SponsorExtraQuestionForceDeleteAuditLog.php, tests/oauth2/OAuth2SummitSponsorExtraQuestionForceDeleteApiTest.php
Question deletion requires an authorized member, a nonblank reason, and confirmation when answers exist. Option deletion removes answers that contain only that option and updates answers that contain other options. Both paths record audit data. Tests cover deletion, answer changes, and audit fields.
API access and usage endpoints
app/Http/Controllers/Apis/Protected/Summit/OAuth2SummitSponsorApiController.php, routes/api_v1.php, database/migrations/config/Version20261009130000.php, database/seeders/ApiEndpointsSeeder.php, tests/oauth2/OAuth2SummitSponsorApiTest.php, tests/oauth2/OAuth2SummitSponsorExtraQuestionForceDeleteApiTest.php
The controller restricts force deletion and usage requests to eligible administrators. The API adds question and option usage routes and endpoint registrations. Tests check access restrictions and usage responses.

Comment thread app/Audit/SponsorExtraQuestionForceDeleteAuditLog.php Outdated
…the delete transaction

The force delete audit only reached the OTLP pipeline (when enabled) and a
warning that the default error log level drops, so a delete could commit with
no durable record. It is now always stored as a SummitAuditLog, in the same
transaction as the delete, and emitted to the log/OTLP after commit.

@romanetar the comment on line 1149 ("the answers reference the question (FK without cascade), so they go first") and the PR description both state the opposite of what the schema does. ExtraQuestionAnswer.QuestionID is declared ON DELETE CASCADE (Version20210521135639 lines 104-106, and SHOW CREATE TABLE ExtraQuestionAnswer on a current DB shows FK_B871C0E03F744DA2 ... ON DELETE CASCADE), and SponsorBadgeScanExtraQuestionAnswer.ID cascades to it as well.

That changes the consequence of the race Copilot describes above rather than removing it: the delete never fails on the FK. An answer committed between getBadgeScanAnswersByQuestion() and the flush is cascade-deleted silently and never counted in audit.answers_deleted, so the audit entry under-reports what was destroyed. Ingestion holds no question-scoped lock (addBadgeScanLocked locks on badge_scan.<sponsor>.<badge>.<member>.<epoch> only), and the transaction runs at the default READ COMMITTED.

Suggested fix:

  1. Correct the comment and the PR description: the explicit loop exists so that the deletion goes through the ORM (orphan removal, LastEdited, onFlush audit), not because the FK would block the delete.
  2. If the undercount matters, lock the question row at the top of the transaction closure: $this->repository->getEntityManager()->lock($extra_question, LockMode::PESSIMISTIC_WRITE). The ingestion INSERT already takes a shared lock on the referenced ExtraQuestionType row when InnoDB checks the FK, so this serializes both sides without touching addBadgeScanLocked. Otherwise, document the window as accepted.

@romanetar confirming this one against the code. getForceDeleteParams() (line 4162) reads reason and delete_answers through $request->input(), which merges the body with the query string, so both are accepted in either location, and the PR description relies on the all-query form for proxies that drop DELETE bodies. The annotations on both DELETE operations (lines 3739-3750 and 4068-4079) document delete_answers as a query parameter only and reason as a body property only, so a generated client cannot build the all-query request the PR says is supported. The new tests use only the documented form (force/delete_answers in the query, reason in the body), so the alternate path is both undocumented and untested.

Suggested fix: on both #[OA\Delete] blocks add new OA\Parameter(name: 'reason', in: 'query', required: false, schema: new OA\Schema(type: 'string'), description: 'Alternative to the body property for clients that cannot send a DELETE body') and a delete_answers boolean property in the request body, and add one test in OAuth2SummitSponsorExtraQuestionForceDeleteApiTest that sends all three in the query string.

@romanetar getBadgeScanAnswersByQuestion() hydrates every answer entity, and two of its three callers only need the count: getSponsorExtraQuestionUsage() (SummitSponsorService.php:1190) and the delete_answers pre-check in deleteSponsorExtraQuestion().

On the destructive path the cost compounds: removeBadgeScanAnswer() triggers one proxy load per badge scan plus one query to initialize the scan's extra_question_answers collection (removeExtraQuestionAnswer calls contains() first, and the mapping on SponsorBadgeScan.php:124 is not EXTRA_LAZY), then the flush issues one DELETE pair and one LastEdited UPDATE per answer, all inside a single transaction. A question answered on a few thousand scans turns the "stuck sponsor" rescue into a multi-second transaction holding locks on those scan rows, which is the same request the admin is waiting on.

Suggested fix: add a countBadgeScanAnswersByQuestion(ExtraQuestionType $question): int (select('count(a.id)') ... getSingleScalarResult()) and use it for the two usage endpoints and the pre-check. Keep the entity loop for the actual deletion so orphan removal and the onFlush audit listener still run; a bulk DQL DELETE would bypass both.
