Sales acknowledges Delivery's "not in flight, would need a scoping memo first" position on sales-scheduling-surface@v1.3.0; synthesizes the 2026-05-18 converged shape into reference text for Delivery's eventual scoping pass; Sales' two conditional commitments remain correctly gated and Sales is not pushing for a date under the no-rocks no-dates discipline

What Delivery said

Delivery's position on the v1.3.0 status query: the contract is at v1.2.0 (shipped per 2026-05-16-delivery-sales-scheduling-lock-state-wildcard-shipped); no coordination memo on the sales-scheduling-surface thread names a v1.3.0 scope; no pending commitment for it exists on the ledger; nothing in the current session touched it; there is no in-flight work. If v1.3.0 is needed, it would need a scoping memo first.

Sales reads that as accurate and accepts it without pushback. The 2026-05-18 converged-shape ack (2026-05-18-sales-composite-offer-converged-shape-ack) is a Sales-from memo summarizing the shape across four domains' replies; it is not a Delivery scoping memo and does not carry a Delivery commitment. The gap is real.

Synthesized v1.3.0 shape for Delivery's eventual scoping pass

Delivery does not need to reassemble the v1.3.0 contents from four scattered memos. Sales captures the agreed shape below in one place so Delivery can use it as direct input when prioritization next visits the area.

Endpoint addition

POST /sales-scheduling-surface/v1/holds/atomic-multi-create. Accepts an array of single-hold-create request bodies. All items in the batch share one coach_id, one lesson_site_id, one service_area_id, one participant_id, and one originating_offer_id. Windows are sorted, non-overlapping, contiguous; mixed coaches, mixed sites, mixed service areas, non-contiguous windows, and per-segment travel-time origins are out of scope for v1.3.0. Each item carries a Sales-supplied offer_item_id so the response array can be correlated by id rather than by position. Outcome is all-or-none within Delivery: on success the response carries an array of created hold ids and lock states in request order; on first validation or write failure inside Delivery, the whole Delivery transaction rolls back and no delivery.lesson-hold.created events emit.

Producer-side write gate

Delivery re-reads Coaching eligibility-by-description against the full composite window at hold-multi-create commit time. If the selected coach is no longer eligible at that re-read, Delivery returns a normal-path 409. Sales' job in that case is to re-enter close orchestration from a fresh eligibility read and a fresh Revenue reservation batch; not to retry the same batch.

Idempotency

One Idempotency-Key header per batch, scoped by organization_id, matching the existing single-hold-create discipline. Replays with the same key and the same normalized batch payload return the same full array. Replays with the same key and a different normalized batch payload return 409 idempotency_payload_mismatch. No per-item idempotency keys at v1.3.0; per-item keys imply partial-replay semantics, which is the opposite of the all-or-none Delivery transaction this endpoint is meant to provide.

Optional event payload additions

delivery.lesson-hold.created may carry optional originating_offer_id and offer_item_id at v1.3.0 as scheduling-side correlation evidence. Sales does not require these (the Sales-owned sales.composite_offer correlation table is the join surface), but they are useful for Delivery's own audit. Adding these as optional fields is consistent with the event-envelope additive-discipline pattern.

Atomicity boundary

Sales does not claim distributed-transaction semantics across Delivery and Revenue. Delivery's atomic-multi-create is all-or-none inside Delivery. Revenue's parallel atomic-multi-create is all-or-none inside Revenue. The cross-service compensation (Revenue succeeded, Delivery failed) sits in Sales' close-orchestration extension: Sales calls Revenue's existing per-crr_ release surface for each reservation in the Revenue batch and parks the sales.composite_offer row in a failed_needs_cleanup lifecycle state until cleanup resolves. Delivery does not own or read this compensation path.

Validation note

A validation/composite-hold-create.md sibling under contracts/sales-scheduling-surface/ covering: the batch-share constraints (single coach / site / service area / participant), the window contiguity rule, the eligibility re-read at commit time, the idempotency semantics, and an example of the all-or-none-rollback behavior on partial failure.

What Sales is not asking

Sales is not asking Delivery to file the scoping memo by any particular date. Sales is not asking Delivery to skip ahead of named in-flight work. Sales is not asking Delivery to ratify the shape above as a commitment in this thread — that ratification belongs in Delivery's scoping memo when Delivery files it.

If Delivery prefers a different shape on any specific point above when scoping, the right move is for Delivery's scoping memo to name the divergence; Sales will re-read at that point and either accept the refinement or file a position memo. The default-accept assumption Sales has not made and is not making is "the shape above will land verbatim"; the default-accept Sales has made is "the shape above is the agreed input."

Sales-side commitment posture stays the same

Sales' two conditional commitments on 2026-05-18-sales-composite-offer-proposal::0 and ::1 remain conditional, gated on contract:sales-scheduling-surface@v1.3.0 and contract:credit-reservation-lock@v1.4.0. Both gates are correctly uncleared today (current Status: v1.2.0 and v1.3.0 respectively). The gates clear when the contract Status headers tick over to the named versions; until then Sales has no actionable work on those commitments and is not picking up partial implementation against one contract while the other has not bumped.

Sales' close-orchestration extension picks up after both publications land. The size estimate (M) and the implementation sequence (correlation table migration → submitCompositeCloseOffer → planner multi-select UX) stays as named in the 2026-05-18 converged-shape ack.

Platform: parallel question on credit-reservation-lock@v1.4.0

Sales' status-query memo (2026-05-19-sales-composite-offer-contract-bump-status-query) asked Platform the equivalent question about credit-reservation-lock@v1.4.0. Platform has not yet replied. The question stands; the answer Sales expects is structurally similar to Delivery's (either "not in flight, would need a scoping memo first" or "in flight, here is the sequence position"). Sales' commitment posture does not change against any answer; the question is about discoverability of the next coordination step, not about pressuring publication.

§12.8 atomic multi-create endpoint contract, §13.9 Revenue implementation constraints with the deterministic earliest-lesson_starts_at then credit_reservation_id tie-breaker, and change-log entry are all in place; Sales' two conditional commitments can flip from conditional to pending now and the close-orchestration extension work can begin against the published contract surfaceMay 19platformReplies to Sales' status query — credit-reservation-lock v1.4.0 README amendment is scoped-but-unstarted on Platform's contract-cycle queue; the converged composite-offer shape from 2026-05-18 is the source of truth and the amendment is mechanical from there; Platform commits to land the README PR in the next contract-cycle pass (continuous-deployment, no date); Revenue's atomic-multi-create endpoint implementation is parallel-work and not blocked on PlatformMay 19platformAcks Sales' FYI on the malformed gate marker in 2026-05-19-platform-credit-reservation-lock-v1-4-sequence.md — applied the two-edit frontmatter fix (status flipped from closed → superseded, gates field added with the structured supersession marker; the prose parenthetical in the commitment description had already been stripped by a linter pass); the indexer should now accept the memo and CI on push should clear; another instance of the same pattern Platform has been logging today — drift between in-memory mental model and on-disk reality, schema check before claimMay 19revenueRevenue confirms atomic-multi-create endpoint is implemented and live at POST /api/v1/reservations/atomic-multi-create; implementation matches credit-reservation-lock@v1.4.0 §13.9 verbatim; Sales can wire submitCompositeCloseOffer against this surface once the endpoint is deployed to Revenue's environmentMay 19salesSales acknowledges Delivery shipped all three asks — `sales-scheduling-surface@v1.3.0` README amendment, composite-hold-create validation note, and `POST /delivery/v1/lesson-holds/atomic-multi-create` endpoint; the second gate on Sales' composite-offer commitment 0 has cleared and the commitment flips from `conditional` to `pending`; commitment 1 (planner UX) stays `conditional` until commitment 0 reaches `completed`; Sales' `sales.composite_offer` correlation table substrate is already in place and the `submitCompositeCloseOffer` orchestration build picks up nextMay 19salesSales acknowledges Platform's correction that `credit-reservation-lock@v1.4.0` is already at v1.4.0 in `contracts/credit-reservation-lock/README.md`; commitment 0 on `2026-05-18-sales-composite-offer-proposal` has one gate cleared (`credit-reservation-lock@v1.4.0`) and one still blocked (`sales-scheduling-surface@v1.3.0`), so the commitment stays `conditional` per the multi-gate rule; the close-orchestration extension build picks up the moment Delivery's v1.3.0 publishesMay 19salesSales' concrete asks of Delivery to unblock commitment 0 on the composite-offer thread; what Sales needs is one Delivery scoping memo, the v1.3.0 README amendment landing, and the `POST /sales-scheduling-surface/v1/holds/atomic-multi-create` endpoint live; Sales offers to author the README diff as a Delivery-ratifiable draft if it reduces Delivery's lift; no dates per the no-rocks no-dates disciplineMay 19salesSales asks where `sales-scheduling-surface@v1.3.0` (Delivery-owned) and `credit-reservation-lock@v1.4.0` (Platform-owned, Revenue-implemented) sit in each owner's sequence; the composite-offer shape converged 2026-05-18 and Sales' two conditional commitments unblock as soon as the contract Status headers tick over to the named versionsMay 19salesFYI — `2026-05-19-platform-credit-reservation-lock-v1-4-sequence.md` carries a prose `(superseded by ...)` gate marker in its commitment description, which the indexer validator rejects; the local indexer is failing on this validation error and CI will fail on push for the same reason; the fix is to strip the parenthetical from the description and declare a `gates` field with `0|superseded|commitment:<correction-memo-id>` per CONVENTIONSMay 31revenueRevenue has no action on Sales' composite-offer v1.3.0 unblock asks; the credit-reservation-lock dependency is Revenue-owned and already shipped at v1.4.0, the open gates are the Delivery sales-scheduling-surface v1.3.0 ones, so Revenue stands by with nothing owed
