📝 WalkthroughWalkthroughThe change replaces quota availability checks with quota consumption. Computation controllers release consumed quotas on failure and pass quota IDs to services. Quota consumption is persisted by result UUID, and build quota consumers now use structured quota state. ChangesQuota consumption flow

Do not release quota while the remote computation can continue.
handleAsymmetricalLoadRequest starts the remote computation before handleQuotaStart saves the local quota-to-result mapping. If that save fails, the controller releases quotaId, but no code cancels or deletes the started computation. The computation can continue without a quota reservation or local quota mapping.
Cancel or delete the computation before releasing the quota.

official Spring Cloud Stream StreamBridge send(String, Message<?>) exception behavior documentation
💡 Result:
<search_synthesis>
The StreamBridge.send(String, Message<?>) method in Spring Cloud Stream behaves according to the underlying Spring Integration MessageChannel implementation [1]. Its behavior regarding success, failure, and exceptions is as follows: Return Values and Exceptions The method returns a boolean indicating the result of the send operation [1][2]. - Returns true: The message was sent successfully to the channel [1]. - Returns false: The message could not be sent due to a non-fatal reason (e.g., the channel might be full or the send operation timed out, depending on the specific channel implementation) [1]. - Throws an Exception: The method may throw a RuntimeException in cases of non-recoverable errors (e.g., binding resolution failures, internal processing errors, or when a function unexpectedly returns null) [1][2]. Implementation Details StreamBridge delegates the sending process to the configured MessageChannel [1][2]. Because it is a synchronous, blocking operation by default (unless setAsync(true) is invoked), the caller is responsible for handling the return value and potential exceptions [3][4][5]. Best Practices Because StreamBridge.send can either return false or throw an exception, robust implementations should use a try-catch block to handle runtime exceptions and explicitly check the boolean return value to confirm successful message delivery [5]. If the method returns false, it indicates that the message was not sent, and you may need to implement retry logic or other error-handling strategies depending on your application's requirements [5].

Prevent quota loss when notification delivery fails.
NotificationService.emitQuotaChange calls the bound StreamBridge.send(...) directly. StreamBridge.send may throw a runtime exception. StudyService.consumeQuota returns the reservation ID only after this call succeeds, so the controller cannot release the quota when delivery fails.
Make the notification best-effort, or release the reservation before rethrowing the exception.

Preserve failed quota releases for retry.
releaseQuotaId catches exceptions from the remote release and returns normally. releaseQuota then deletes the QuotaConsumptionEntity mapping, even when the remote release fails. The mapped release path therefore loses the quotaId needed for a retry.
Propagate or return the release failure, and delete the mapping only after a successful release. This correction applies to releaseQuota; direct releaseQuotaId callers pass the quota ID directly and do not use this mapping.
