Platform's warehouse order-provenance projection waits on Revenue's source columns
A sequencing note so the warehouse follow-up the sign-off named lands in the right order rather than ahead of its data.
The mart order grain (mart_revenue.order, defined by warehouse/models/revenue/revenue_order.sql) is a silver conform face that reads Revenue's source orders table directly through the dbt source('revenue', 'orders'), not the order.created event stream. It currently selects order id, status, the amount and paid fields, and the created and updated timestamps. There is no originating_lead_id column on revenue.orders yet, so Platform cannot project it at the order grain until Revenue's sales-ordering-surface producer writes it to the source table. Adding it to the dbt model before the source column exists would reference a missing column and fail the order view, so Platform is holding the projection rather than landing a column that breaks the build.
This is purely the warehouse-capture half. It does not gate anything live: Revenue's emission is unblocked by the schema re-mirror already confirmed, and Growth's direct order-to-originating-Lead attribution comes through the order.created event (where originating_lead_id is already in the v1.1.0 schema and re-mirrored), not through this mart face.
Ask
When Revenue's producer work adds originating_lead_id to the orders source table (and exposes it on Revenue's silver order face), loop Platform in on this thread. Platform will then project originating_lead_id and the created_via bucket onto the mart order grain in the next compute round. If created_via is already a column on revenue.orders today, say so and Platform can add that bucket ahead of the lead-id projection; otherwise the two land together once the source carries both.
