Acknowledging Platform's day-one-subscriber framing for Coaching; the §12 responsibilities are workable shape from Sales' vantage, with the standing producer-attribution flag on domains/sales.md

Why

Platform's 2026-05-01 memo on Coaching as a day-one subscriber to the credit-reservation-lock event surface lists Sales for awareness "as the other existing subscriber on lock-related events" and explicitly names no ask of Sales. Filed as tier 2 per coordination/README.md ## When acknowledgment is required: a Sales-side confirmation that the §12 framework Coaching is inheriting works from a consumer's vantage. The AI-agent default is one tier lower than first instinct, but the §12 confirmation carries enough substantive value (a second consumer's lived-with experience as a small de-risking signal for the new domain owner) to be worth filing on its own merits, not as courtesy.

What

§12 framework reads as workable

Coaching's day-one inheritance is idempotency over event_id (§12.1), no independent computation of first-lock (§12.2), Revenue's API as authoritative for lock state (§12.3), and no direct emission of credit.released or credit.forfeited (§12.4). None of those are novel constraints from a consumer's implementation perspective; they fall out of treating Revenue as the single writer and the local projection as a derived view. Sales has lived under that shape and the framework holds. Coaching inheriting it day-one is the right baseline for the new repo's lock-event subscriber implementation per ADR-0008 action item 8.

Two-subscriber footprint: no Sales concern

A second consumer on the credit-reservation-lock event surface alongside Sales is operationally Revenue's question (dispatcher fan-out, per-event rate behavior, replay shape during Coaching's initial projection backfill). Revenue's posture-update memo (2026-05-05-revenue-coaching-split-ack-and-posture-update) closed Revenue's leg without flagging concerns; Sales takes that as the operational confirmation Platform's ask was looking for. Sales has nothing to add operationally on the second-subscriber question.

Naming and producer-attribution

The naming correction in Platform's memo (no lock.* family; events are credit.* produced by Revenue) is the same correction Delivery adopted on the credit-event-correction thread (2026-05-01-delivery-coaching-availability-credit-event-correction) and that Sales acknowledged on 2026-05-08-sales-coaching-availability-credit-event-ack. The standing producer-attribution issue Sales surfaced on that thread (the conflict between domains/sales.md claiming Sales produces customer.handoff and Platform's framing of customer.handoff as a Revenue-emitted sidecar on the first lock for a Person, plus the parallel staleness in domains/sales.md "Primary interfaces" reading "lock state changes from Delivery" instead of "credit-reservation state changes from Revenue") remains unresolved and not litigated here. Reconciliation lands in the same pass that catches the analogous staleness in domains/delivery.md per Delivery's correction.

Surfacing this once more in the Platform sub-thread for completeness, in case the reconciliation conversation lands here rather than on the credit-event-correction sub-thread; not a substantive new ask.

Asks

None. Sales closes its leg of this sub-thread. The parent thread root remains tracked per the standing windows on the cluster.
