SIE.Preface:6.1 - A shared request limit changes the provider result
Consider a constructed variation of APP-SIE-04. The receiving contract allows an explicitly incomplete purchasing answer. Assume that adequate models and the required source, correspondence, identity, and composition premises have been supplied. Provider A still means “on hand”; provider B means “available to promise”; their claims must keep those meanings. Permissions allow live retrieval and the agreed immediate presentation, but prohibit replication.
For this illustration, four calls retrieve A’s required rows, four retrieve B’s, and three retrieve the common source and rule trace required even for a partial answer. All calls consume one gateway allowance of ten requests in the agreed request window; none is shared or counted twice. Retries also consume the allowance, and the contract accepts neither a copied cache nor deferral to another window for this answer. Each pair of contributions fits: 8, 7, or 7 calls. The complete answer requires at least 11 before retries, so pairwise feasibility does not establish the whole arrangement.
SIE.8 therefore cannot select that arrangement as supplying the complete result. Under the stated incomplete-answer permission, an A-only result with the required trace uses seven calls before retries and can be proposed with B explicitly marked as not retrieved under the request limit. SIE.9 must preserve A’s on-hand meaning and the incomplete branch; it must not render B as zero stock or call the response a complete provider comparison. For example, an A source value on_hand = 12 observed at T becomes a receiving row 12 on hand at T, with its source and rule trace and the branch B not retrieved. It supplies no available-to-promise value.
SIE.10 tests the remaining required conditions before any bounded positive validation. If both providers are mandatory, return a stop and the exact missing result: for example, an access-owner decision changing the allowance or an implementation that demonstrably reduces calls while preserving meanings and trace. Omitting provenance is not an equivalent repair.
The quantities are construction assumptions, not measurements of providers. Actual use needs evidence for the gateway condition, call demand, permissions, freshness, behavior under failure, and the receiver’s interpretation. Passing source lookups or several pairwise tests cannot supply that evidence for the whole. A changed allowance reopens the affected realization and use validation; an unchanged correspondence can remain usable.
Constituent actions in ongoing work. While processing an exchange, resolving a source identifier can constitute part of interpreting a correspondence, within an ongoing integration of the receiving information. If the receiving use changes from present eligibility to eligibility at an earlier date, a lookup that returns only the present subject state is no longer sufficient. The team may have parser and database skills but lack the intermediate meaning or temporal-identity account. Supply that contribution through the relevant SIE Method rather than treating a successful query as a successful integration. FPF B.1.5.EW helps recover the connection; SIE.8 and SIE.10 keep the whole arrangement and its warranted validation in view.
