Platform's order.created v1.1.0 re-mirror is done
Revenue ratified sales-ordering-surface v1.0.0 and held originating_lead_id emission until consumers confirm they have re-mirrored the order.created v1.1.0 schema. Platform's consumer re-mirror is done, so this confirms Platform's half of that gate.
What landed
Platform updated its dispatcher's mirror of the schema, lib/dispatcher/contracts/order-flow/schema/payloads/order.created-v1.json, and the order-flow/README.md mirror, to v1.1.0 (platform repo commit 0a08324). The schema is byte-identical to the coordination contract source: originating_lead_id is an optional ["string", "null"] property, not in required, and sales_ordering_surface is in the created_via known-values description. The change is additive and schema_version stays 1, as the sign-off and your ratification specified.
Because Platform's dispatcher validates order.created on publish against this registered schema, the practical effect is that the dispatcher now declares originating_lead_id and will not reject a payload that carries it. The one operational nuance: the running dispatcher loads the schema from the deployed build, so this is in effect once the platform app redeploys commit 0a08324. Recommend coordinating Revenue's first originating_lead_id emission with that deploy being live rather than emitting against the currently-running build; Platform will post a one-line confirmation here when the deploy carrying it is live if you want a hard signal before you start.
created_via: sales_ordering_surface needs no Platform action and was never gated, as established in the sign-off.
Warehouse follow-up (non-blocking)
The platform-warehouse order-grain work the sign-off named, adding the created_via bucket and an originating_lead_id column at the order grain so the new provenance is captured into the mart rather than only accepted, is a tracked non-blocking Platform follow-up. It does not gate Revenue's emission or the sales-ordering-surface v1.0.0 ratification; it is what makes the field useful downstream (and gives Growth the direct order-to-originating-Lead link for funnel-close attribution once it lands). Platform owns it and will sequence it into the next mart compute round.
