Summary

add optional occurredAt metadata to the shared world event creation contract and event schema
send occurredAt through world-vercel v4 event frame metadata, defaulting to the client-side post time
preserve occurredAt on returned v4 events and keep world-postgres schema typing compatible until it persists the field

Summary

add optional occurredAt metadata to the shared world event creation contract and event schema
send occurredAt through world-vercel v4 event frame metadata, defaulting to the client-side post time
preserve occurredAt on returned v4 events and keep world-postgres schema typing compatible until it persists the field

Summary

add optional occurredAt metadata to the shared world event creation contract and event schema
send occurredAt through world-vercel v4 event frame metadata, defaulting to the client-side post time
preserve occurredAt on returned v4 events and keep world-postgres schema typing compatible until it persists the field

Summary

add optional occurredAt metadata to the shared world event creation contract and event schema
send occurredAt through world-vercel v4 event frame metadata, defaulting to the client-side post time
preserve occurredAt on returned v4 events and keep world-postgres schema typing compatible until it persists the field

Summary

add optional occurredAt metadata to the shared world event creation contract and event schema
send occurredAt through world-vercel v4 event frame metadata, defaulting to the client-side post time
preserve occurredAt on returned v4 events and keep world-postgres schema typing compatible until it persists the field

Summary

add optional occurredAt metadata to the shared world event creation contract and event schema
send occurredAt through world-vercel v4 event frame metadata, defaulting to the client-side post time
preserve occurredAt on returned v4 events and keep world-postgres schema typing compatible until it persists the field

Summary

add optional occurredAt metadata to the shared world event creation contract and event schema
send occurredAt through world-vercel v4 event frame metadata, defaulting to the client-side post time
preserve occurredAt on returned v4 events and keep world-postgres schema typing compatible until it persists the field

Summary

add optional occurredAt metadata to the shared world event creation contract and event schema
send occurredAt through world-vercel v4 event frame metadata, defaulting to the client-side post time
preserve occurredAt on returned v4 events and keep world-postgres schema typing compatible until it persists the field
