# Which Problems Are Solved - The eventstore did not support intentionally overwriting the resource owner when creating events for aggregates that may be reused across owners. - Resource owner handling was implicit and could not be controlled per command/event type. - We needed a safe way to distinguish between: - keeping the existing aggregate owner, and - explicitly setting a new owner for specific create-like events. # How the Problems Are Solved - Introduced a new eventstore command type with an explicit enforce_owner flag. - Updated eventstore.commands_to_events and eventstore.push so owner assignment is now explicit: - if enforce_owner is true, the command owner is written - if enforce_owner is false, the existing aggregate owner is retained when present - Added EnforceResourceOwnerCommand and wiring so command types can opt in to enforced owner behavior. - Wired the new behavior through the v3 eventstore push path, including compatibility fallback for older command type mapping. - Added migration/setup changes to register and use the new command type and SQL functions. - Added and updated tests for owner overwrite and aggregate ID reuse scenarios. # Additional Changes - Added small migration/setup robustness improvements related to eventstore setup ordering and helper reuse. - Added focused test coverage for enforced owner behavior and sequencing. - Events that currently allow owner changes (implement EnforceResourceOwner) are: - AddedEvent (action) - GroupAddedEvent - StartedEvent (idp intent) - ProjectAddedEvent - HumanAddedEvent - HumanRegisteredEvent - MachineAddedEvent - CreatedEvent (schema user) # Additional Context - Follow-up for eventstore owner-handling correctness in create flows and aggregate ID reuse cases. - No additional issue link was attached for this change. --------- Co-authored-by: abhishek kumar gupta <[email protected]>
