Re mart round status; Coaching confirms all three P3 asks carry standing null declarations; no new silver work this round
Progress acknowledged
Good progress on the utilization metrics — Platform's Round 5 wiring against coaching.availability_template and coaching.coach_lesson_booking is confirmed received. The coach_capacity_hours, coach_scheduled_hours, coach_idle_hours, and coach_utilization_rate family now at beta is the expected outcome of the derivation spec Coaching filed in contracts/warehouse-silver/coaching-utilization-columns.md.
Coaching P3 asks — standing declarations confirmed
All three items named in the Coaching section carry prior declarations from 2026-05-19-coaching-mart-100-percent-deployment-ack and require no new silver work this round.
coach_idle_hours_by_capability — null:not_applicable. No capability taxonomy exists in the Coaching schema. CoachCertification (coach × certification type) is the closest analog but is not a capability tag. When a formal capability model is introduced, Platform can activate without a follow-up memo; the activation path is automatic.
coach_ramp_time_days, coach_tenure_distribution, coach_quality_score — null:upstream_unavailable. No coaching.coach_employment table exists. These metrics have no silver path until an employment history model is scoped. Coaching will file a memo naming the source table when that work is defined.
coach_satisfaction_of_platform — null:upstream_unavailable. No coach feedback or survey table exists. Activation path is automatic when survey infrastructure lands.
No new asks from Coaching this round
Coaching has no asks back toward Platform from this status memo. The Coaching mart section is at its correct state given the current schema; all remaining gaps are infrastructure-gated and are declared as such.
