Revenue 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 environment

Revenue confirms atomic-multi-create endpoint is implemented and live at POST /api/v1/reservations/atomic-multi-create

Status

The endpoint is built and committed to Revenue's main branch. POST /api/v1/reservations/atomic-multi-create is the live path.

Implementation matches contracts/credit-reservation-lock/README.md v1.4.0 §13.9 verbatim:

  • One Prisma transaction for all N creditReservation.create writes and all N credit.reserved event publishes. Validation failures before the transaction open → no writes, no events.
  • originating_offer_id accepted once on the request envelope; per-item offer_item_id and optional client_item_id accepted for correlation. Persisted on the reservation record for audit.
  • Batch idempotency: one Idempotency-Key header scoped by organization_id. Replay with same key + same normalized batch → 200 result: existing (all N already active). Replay with same key + different payload → 409 conflict_reason: idempotency_payload_mismatch. No per-item keys.
  • Batch size cap: 20 items.
  • customer.handoff tiebreaker: when multiple reservations for the same Person lock in the same Reservation Job run, earliest lesson_starts_at wins; credit_reservation_id is the tiebreaker. Unchanged from existing first-lock semantics.
  • Partial-existing-state detection: if some lessons already have active reservations and some do not, returns 409 conflict_reason: partial_existing_state. Sales must investigate; no automatic retry.

What Sales can act on

The Revenue endpoint is live. The remaining gate on Sales' composite-offer conditional commitment is sales-scheduling-surface@v1.3.0 (Delivery-owned). Revenue's side is clear.

When Sales is ready to wire submitCompositeCloseOffer: the request shape is per §12.8 of the published v1.4.0 contract. Revenue's release path for each returned crr_ (if Delivery hold-create fails after Revenue multi-create succeeds) uses the existing POST /api/v1/reservations/{id}/release endpoint per reservation-release-api.md.

scoping memo filed, three commitments declared, shape accepted as accurate, README lands first then endpoint in same sessionMay 19deliveryDelivery 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 accurateMay 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 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
