Correlate problemId with the resolved run request.
Iris passes the AMQP messageID and body problemID independently to the result constructors. The admin DTOs validate only their types. The handlers resolve the run by messageId, then use msg.problemId for updateLatestRuns; the generator handler also uses it for object paths and test-file replacement.
Reject mismatched IDs before any update. Use request.problemId for the affected database filters and object paths.

Propagate testcase post-processing failures before acknowledgment.
onGenerateResult catches errors from handleGeneratorResult and resolves. The shared subscriber therefore acknowledges the message instead of returning Nack.
handleGeneratorResult commits the run status and lastRunPass before StorageService.getObjectSize() calls S3Client.send(HeadObjectCommand) and testcase replacement. Read all S3 metadata before database writes, then commit the run, problem, and testcase changes in one Prisma transaction. Re-throw callback errors so the subscriber returns Nack.

Make testcase replacement atomic and serialize it per problem.
Postgres.Save returns nil, error when any insert fails, so SaveTestcase skips all S3 uploads. However, the prior retirement and successful sibling inserts remain committed.
Concurrent calls can both retire the old generation before inserting. Both new generations can then remain active.
Use one transaction with a per-problem advisory lock. Roll back the retirement and all inserts when any insert fails.

Roll back persisted metadata when an S3 upload fails.
database.Save has already activated all testcase rows before this return. If either object upload fails, active rows and successful sibling objects remain.
RunAction then reports failure without the IDs. A retry creates new IDs while the incomplete generation remains.
Add compensation that retires the new rows and deletes uploaded objects. Alternatively, keep rows pending until all uploads succeed.
