Context & Requests for Reviewers

The "This is an Appeals Queue" checkbox only appeared when creating a queue, so a queue could never be converted to or from an appeals queue after the fact. This PR adds that to the edit form.

  • Client: the checkbox now shows on the edit form (still gated on the org's "enable appeals" setting), and the update mutation sends isAppealsQueue.
  • GraphQL (additive): optional isAppealsQueue on UpdateManualReviewQueueInput, plus a new UnableToChangeQueueTypeError in the update response union.
  • Server: QueueOperations.updateManualReviewQueue performs the conversion. A converted queue becomes the default of its new type if the org has none, mirroring creation.

Regular and appeals jobs live in separate Bull queues with different payload shapes, and routing rules are type-specific, so the server refuses a conversion that would orphan anything. It returns UnableToChangeQueueTypeError when the queue is the default queue, still has pending jobs, or is referenced by a routing rule. The form shows that message.

Review focus: the refusal rules in #assertQueueTypeCanChange (QueueOperations.ts). In particular, whether refusing to convert the default queue is the right call versus reassigning the default.

Tests

  • Server integration tests in QueueOperations.test.ts: conversion both ways, promotion to default appeals queue, the no-op case, and each refusal.
  • Client tests in ManualReviewQueueForm.test.tsx: checkbox visibility with appeals on/off, saved variables, and the error modal.

(Optional) Rollout Plan

None. Schema changes are additive.

Checklist

Only check items that apply to this PR; leave the rest unchecked.

  • If you changed anything user-facing (i.e. user interface or APIs):
    Did you update related docs?

  • If the change is notable (refer to Keep a Changelog conventions):
    Did you update CHANGELOG.md?

  • If you changed server/models/**/{ContentTypeModel,ActionModel,RuleModel,PolicyModel}.ts:
    Did you update the corresponding history tables and their triggers?

  • If you changed db/src/scripts/** and used CREATE TABLE, ADD COLUMN, or ALTER COLUMN:
    Are as many columns marked NOT NULL as possible? If some columns can sometimes be null depending on other columns, are there CHECK constraints capturing those relationships, and are these also reflected using unions in the associated Kysely types?

  • If you added a new signal in server/services/signalsService/signals/**:
    Did you classify every error case as a permanent error (SignalPermanentError, no retry) or a normal error (retryable)? Any case where the signal can't determine a score should be a SignalPermanentError.

📝 Walkthrough

Walkthrough

The update flow now supports converting existing manual review queues to or from appeals queues. The server validates queue state, routing rules, and pending jobs. The edit form submits the conversion state and displays conversion errors.

Changes

Manual review queue type conversion

Layer / File(s) Summary
Queue conversion rules and validation
server/services/manualReviewToolService/modules/QueueOperations.ts, server/services/manualReviewToolService/modules/QueueOperations.test.ts
QueueOperations validates queue defaults, routing rules, and pending jobs before conversion. It updates the queue type and assigns a new-type default when needed. Tests cover successful conversions, unchanged values, and rejected conversions.
GraphQL and service wiring
server/graphql/modules/manualReviewTool.ts, server/services/manualReviewToolService/manualReviewToolService.ts
The update input accepts optional isAppealsQueue. The value reaches QueueOperations. UnableToChangeQueueTypeError is exposed through the GraphQL response union.
Edit form and client validation
client/src/webpages/dashboard/mrt/ManualReviewQueueForm.tsx, client/src/webpages/dashboard/mrt/ManualReviewQueueForm.test.tsx, CHANGELOG.md
The edit form shows the appeals checkbox when enabled, submits its value, displays conversion constraints, and renders server-provided conversion errors. Client tests cover visibility, state, saving, and failure handling. The changelog records the change.

Merge Risk: 🟡 Moderate · up to 620af

A queue can be converted while a job or routing rule is concurrently added, leaving type-specific work or routing attached to the wrong queue type. Serialize conversion with those writes before merging.

The "This is an Appeals Queue" checkbox only appeared when creating a
queue, so a queue created without it could never be marked as an appeals
queue afterwards. The edit form now shows the checkbox whenever appeals
are enabled for the org, and `UpdateManualReviewQueueInput` accepts an
optional `isAppealsQueue`.

Regular and appeals jobs live in separate Bull queues with different
payload shapes, and routing rules are type-specific, so the server
refuses a conversion that would orphan anything: the default queue,
a queue with pending jobs, or a queue referenced by a routing rule.
These are returned as a new `UnableToChangeQueueTypeError` so the form
can show the reason. A converted queue becomes the default of its new
type when the org has none, mirroring creation.

Serialize queue-type conversion with pending-job and routing-rule checks. #assertQueueTypeCanChange runs through this.pgQuery before transactionWithRetry, while JobRouting.createRoutingRule, AppealsJobRouting.createAppealsRoutingRule, QueueOperations.addJob, and QueueOperations.addAppealJob can write after those checks. A rule or job created in that window can remain associated with a queue after is_appeals_queue changes, while regular and appeals jobs use separate Bull queues and payload types. Move the checks into the conversion’s serialized critical section, and use the same lock or serialization protocol for routing-rule creation and both enqueue paths. A transaction boundary alone is not sufficient for the Redis-backed job writes.
