Caution Review failedThe pull request is closed. WalkthroughThe changes remove checks that previously prevented the creation of duplicate or concurrent workflow instances by commenting out logic that searched for existing running workflows before creating new ones. Additionally, workflow names in configuration files are updated to include environment-specific suffixes for clarity. Changes

PR Summary
Modified email processing pipeline configuration and workflow management, focusing on environment separation and concurrent processing capabilities.
- Updated workflow naming in
apps/server/wrangler.jsoncby adding environment suffixes ('-staging', '-prod') to prevent naming collisions - Removed workflow instance checks in
apps/server/src/pipelines.tsfor MainWorkflow, enabling parallel processing - Commented out last page fetching logic in ZeroWorkflow
- Disabled thread workflow instance verification, potentially allowing concurrent thread processing

logic: Removing the duplicate workflow check could lead to multiple concurrent workflows processing the same history. Make sure this is the intended behavior and that concurrent processing is handled properly.

logic: Removing last page processing means only history-based updates will be processed. Verify this won't miss any critical updates that might not trigger history events.

Bug: Thread Workflow Duplicate Processing
The THREAD_WORKFLOW duplicate prevention logic, including the existing instance check and deterministic ID assignment (${threadId}__${connectionId}), has been commented out. This allows multiple workflow instances to be created for the same thread and connection, resulting in duplicate processing, race conditions, resource waste, and potential data corruption.

Bug: Workflow Duplication Causes Resource Waste
The duplicate workflow prevention logic for ZERO_WORKFLOW and THREAD_WORKFLOW instances has been commented out. This includes the check for existing running instances and the use of deterministic IDs for workflow creation. As a result, multiple workflow instances can be created for the same history or thread, leading to duplicate processing, resource waste, race conditions, and potential data inconsistencies.

Bug: Recent Emails Processing Issue
The lastPage processing logic was commented out, which removes the processing of the most recent 10 inbox threads. As a result, recent threads not captured by Gmail history changes (e.g., threadsAdded, threadsAddLabels, threadsRemoveLabels) will not be processed. This leads to a functional regression where new or recently updated emails may be missed.
