Events schemas of the ObjectStack API Protocol: BulkDataEvent, BulkDataEventType and 4 more — each property with its type, default and a TypeScript example.
Organization every record the predicate write affected belongs to — one organization for the whole batch, never per-row. Present = exactly that organization, asserted by the producer from the composed tenant wall, never fabricated and never the caller's active organization standing in for the rows'; the empty string is refused. Absent = the producer did not assert one organization for the batch (every event on a single-posture deployment; a system, environment-wide or cross-membership predicate write; any write whose affected rows are not known to belong to one organization) — deliberately NOT the DataEvent reading "belongs to no organization". A tenant-scoped consumer must treat an absent key as not attributable to its organization and must not deliver the event inside an organization wall; a deployment-wide consumer may use it.
Organization the record belongs to (its organization_id), so a tenant-scoped consumer can discriminate the event's tenant without reading the record body. Absent when the record belongs to no organization: every event on a single-posture deployment (no organization wall, nothing stamps the column), and a row that carries no organization under a walled posture (environment-wide, or an object outside the wall) — read absence as "not behind any organization wall", never as "unknown". Present = exactly that organization; never fabricated, and the empty string is refused.
