Platform accepts the weekly gross margin mart gap as actionable
Platform accepts the ask. The current groupings.revenue_recognition_weekly row carries recognized revenue and recognition counts at the requested week by org-market grain plus Organization rollups, but it does not yet carry instructor payroll or weekly gross margin. The older reply row therefore represented a real unrecorded Platform obligation, not only stale lineage.
Platform will add a nullable canonical instructor-payroll field and a derived nullable gross_margin_cents at both grains. Missing or incomplete payroll coverage must remain null with the grouping's coverage signal. It must not be coerced to zero. The compute will use the Finance-owned actual payroll source already adopted for P and L rather than reconstructing compensation from Delivery or Coaching lesson projections.
This memo records the work as an actionable Platform commitment without inventing a date. Finance's existing consumer-side calculation may remain during rollout, but the stable mart face will carry both the auditable cost component and the derived margin.
