Platform acknowledges the exact assembled ADR-0052 architecture and contract package

Assignment ADR-0052/platform/005; coordinator 01a0e095-f279-7fd0-a8ef-92ce8f9547fc, host local; participant 01a0ff07-c6a3-7000-81a3-94f9960a4513. Platform formally acknowledges ADR-0052 and the exact collected contract package at Git commit a09199b69dec7fff1a32d50e22567539455e2e0b, coordination PR 3. This is Platform's own architecture and contract approval, not another owner's position or runtime readiness claim.

The prior review at c114a77d3319e8a36d3edd0e9043e4972b895cc7 identified only the wrong-method validation inconsistency. The new commit contains all four correction files and Platform's findings memo byte-for-byte against the supplied SHA256 manifest. The only other additions since that reviewed commit are owner acknowledgment memos; no additional contract semantics changed. Wrong method on an exact scheduling route is now 405 in the model and vectors, while wrong-route authority remains denied. This resolves Platform's sole package blocker and supersedes its withheld acknowledgment in the collected-package review.

Platform approves scheduling v2.0.0 and the workload/bind-settlement and compatibility/release sub-specs; service-auth v1.8.0; credit-reservation-lock v3.5.0 and bind-evidence v1.0.0; reservation-release-api v1.1.0; and compatible sales-ordering v2.9.0. The four exact policy identities, subjects, scalar audiences, singleton tenant/Organization reach and method/path/query bounds are accepted. Existing default, operator, closure and Coaching authority remains unchanged. No generic inspection, cancellation/refund, financial operation or fifth legacy receipt capability is introduced. Current exact access and retained original identity precede receipt/evidence disclosure.

Platform ratifies exact enabled active-Organization roles sales/owner/admin conjunctively with fresh trusted matching-user bootstrap and Sales app verdicts, with no global app-map change, SuperAdmin-only bypass or configured tenant fallback. Valid immutable v2 command admission becomes service-owned under current service/resource authority; original actor/request/key remain unchanged after initiating-human access loss. Each individual attempt on all four paths obtains distinct successfully audited no-store authority without persisted credentials. Issuance disablement does not instantly revoke an already-issued offline token; residual validity remains bounded by 300 seconds plus accepted clock tolerance capped at 30 seconds.

The continuation correction is accepted: Delivery installs nonexpiring intent-owned protected booking in the bind/receipt transaction; Revenue retains or atomically transfers financial protection before durable provider dispatch; unknown provider/writeback stays protected; terminal settled/abandoned is irreversible and cannot reopen original collection. Delivery reads exact terminal evidence outside locks, then rechecks original intent/receipt/resource identity and CASes the same protection generation before retirement and ordinary writer evaluation. Shared lock order, common invalidating-writer barriers, independently resolvable financial terminal decisions and retained reconciliation uncertainty avoid a cross-domain network-held-lock protocol. Indefinite safety protection for genuine unknown outcomes is explicit, not an unsupported liveness promise.

Incoming genuine payment/refund and operational facts remain recordable; contradictory protected progression defers without suppressing financial truth. Immutable admission reservation revision, coherent current closureRevision and current intent CAS revision remain distinct. Permanent noncommit defeats delayed bind. Stable original preparation/provider attempts and protected writeback recovery prevent fresh-ID reconstruction or duplicate collection. These are accepted obligations; actual writer coverage, external effects and serialization remain later proof requirements.

Permanent admission-specific v2 identity, exact wire/receipt bytes and strict shared normalization are accepted, with no automated legacy execution/receipt replay or inferred historical admission. Scheduling's major compatibility change is explicit; Sales-to-Revenue request/success/error shapes remain compatible under ordering v2.9. The planned cutover attempt is at most four hours with explicit checkpoint and safe-paused extension decision; deprecation is at most 14 calendar days from actual accepted scheduling v2 publication. Protected rollback retains auth, journals, fences, keys/tombstones and quarantine. These bounds do not start live maintenance.

Reused the pinned collected static evidence and the already-passed corrected Platform 188-vector plus 8-boundary check; did not duplicate suites after verifying identical corrected bytes. The assembled commit preserves portable offline validators, pinned dependencies and fail-closed Python date-time checking. This establishes contract evidence only, not cryptographic exchange, deployed authority, no-denial-effects proof or runtime race safety.

Platform approves the coordinator's mechanical removal of proposal-only publication labels and ADR acceptance transition after all required owner approvals, provided the reviewed semantics and separate runtime gates remain unchanged. Any material semantic alteration requires renewed owner review. Accepted atomic publication precedes separately assigned implementation. Actual production workload acquisition/exchanges, issuer/recipient changes, all-writer/sender exclusion, provider uncertainty and compensation, real route denial/replay/concurrency, crash recovery and protected deployment/cutover remain implementation/activation gates.

Live Platform inbox/ledger discovery was refreshed during verification; no implementation commitment is claimed completed. Only this acknowledgment is prepared in Platform scratch for the coordinator's batch. No root-checkout edit, independent publication/indexer/freshness run, token issuance, application change, database mutation, live pause or deployment occurred. The coordinator remains sole publisher and owns the final indexer/freshness steps.
