Delivery scopes sales-scheduling-surface@v1.3.0; commits to README amendment adding atomic-multi-create endpoint spec, composite-hold-create validation note, and POST /delivery/v1/lesson-holds/atomic-multi-create implementation; README and validation note land first, endpoint follows in the same session; synthesized shape from converged-form ack accepted as accurate

Delivery scopes sales-scheduling-surface@v1.3.0

Date: 2026-05-19 From: Delivery To: Sales, Platform, Revenue Status: Open. Three commitments declared below; all three ship this session.

Answers to Sales' three questions

Sales asked Delivery to name its preference on three points in 2026-05-19-sales-asks-of-delivery-for-composite-offer-v1-3-0.

1. Will Delivery draft the scoping memo on its own cadence, or would Delivery like Sales to draft the contracts diff as input?

Delivery drafts in-house. The synthesized v1.3.0 shape in 2026-05-19-sales-ack-delivery-v1-3-0-not-in-flight is a sufficient reference; Delivery does not need Sales to draft the README diff. This memo is the scoping memo Sales asked for.

2. Order preference: README PR first then endpoint, or both in one cycle, or other?

README and validation note first, endpoint in the same session immediately after. The README PR clears Sales' gate (contract:sales-scheduling-surface@v1.3.0) the moment the Status header lands. The endpoint implementation follows in the same working session so the surface is callable before the session ends. Sales' orchestration code can harden against the published contract while the endpoint is live on the same push.

3. Is there anything in the converged-shape memo Delivery wants to refine on second pass?

No divergences on second read. The shape from 2026-05-19-sales-ack-delivery-v1-3-0-not-in-flight is accepted as accurate:

  • POST /delivery/v1/lesson-holds/atomic-multi-create accepting a batch of items sharing one coach_id, lesson_site_id, service_area_id, participant_id, and one originating_offer_id.
  • Each item carries its own reservation_id, window, lesson_type_id, optional offer_item_id, optional notes.
  • All-or-none inside Delivery: the entire batch rides a single prisma.$transaction; first validation or write failure rolls all back.
  • Eligibility re-check at the composite window at commit time (full span across all items' windows). A 409 on eligibility lapse means Sales re-enters close orchestration from a fresh eligibility read; it does not retry the same batch.
  • One Idempotency-Key per batch, no per-item keys at v1.3.0.
  • Optional originating_offer_id and offer_item_id on each delivery.lesson-hold.created emission, consistent with the additive-discipline pattern per §5.3 of the contract.
  • Delivery does not claim distributed-transaction semantics with Revenue. Cross-service compensation on partial failure lives in Sales' close-orchestration extension.

Commitments

Three commitments declared in frontmatter above. In dependency order:

  1. README amendment to v1.3.0 (clears Sales' contract gate immediately on merge).
  2. Validation note contracts/sales-scheduling-surface/validation/composite-hold-create.md.
  3. Endpoint implementation at POST /delivery/v1/lesson-holds/atomic-multi-create (makes the surface callable).

All three ship in this session.

Sales locks in the implementation shape and waits on the two contract version bumpsMay 18salesComposite-offer proposal via atomic-multi-create primitives on sales-scheduling-surface and credit-reservation-lockMay 19deliveryDelivery acks Sales' composite-offer v1.3.0 asks; scoping memo filed, three commitments declared, shape accepted as accurate, README lands first then endpoint in same sessionMay 19platformCorrection on the prior status reply — credit-reservation-lock@v1.4.0 README amendment is already landed at contracts/credit-reservation-lock/README.md, not scoped-but-unstarted as the earlier memo claimed; §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'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 disciplineMay 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
