A.2.3:5 - Archetypal grounding (engineer‑manager friendly)
Worked-case premise. E.24.UK has already admitted the public U.System kind. Every exact entity named as a system in the rows below independently satisfies the complete A.1 criterion, including acting eligibility. If that premise cannot be established, keep the exact entity without system membership and stop only the provider-assignment, access-point, delivery-system, or Work-attribution claim that depends on it; other direct claims may continue under their subject patterns.
| Domain | Promise-content episteme | Provider and consumer assignments | Access specification | Delivery work | Evidence and evaluation |
|---|---|---|---|---|---|
| Cloud storage | Store and retrieve blobs up to 5 TB under declared criteria—for example, 99.9% availability and 99.999999999% durability (eleven nines); these values illustrate targets and are not defaults. | CloudStoragePlatformSystem holds StorageProviderSystemRole; BackupControllerSystem holds StorageConsumerSystemRole, each through an A.2.1 assignment occurrence and its declared species. | S3ApiDescription-vX, a U.MethodDescription; the endpoint is a separate bearer, treated as a U.System under the worked-case premise. | Dated PUT, GET, replication, and integrity-check Work occurrences participating in PromiseContentUse. | Request and integrity observations enter direct evidence relations; evaluation applications bind availability or durability results, and separately constituted verdict epistemes state the judgments. |
| Manufacturing utility | Deliver compressed air at 8 bar in Zone B under stated pressure, flow, and purity criteria. | CompressedAirPlantSystem holds UtilityProviderSystemRole; LineBSystem holds UtilityConsumerSystemRole, each through an A.2.1 assignment occurrence and its declared species. | ZoneBManifoldAccessDescription, a U.MethodDescription; the manifold is a separate bearer, treated as a U.System under the worked-case premise. | Dated compression and delivery Work occurrences. | Pressure, flow, and purity observations support delivery claims; an evaluation application binds the comparison result under the declared scale and window, and a verdict episteme states the judgment. |
| Public passport service | Issue an admissible passport within 20 days under declared defect and eligibility criteria—for example, a ≤ 1% defect target; this value is illustrative, not a default. | IssuingAgencySystem holds PassportIssuerSystemRole; ApplicantPersonSystem holds PassportApplicantSystemRole, each through an A.2.1 assignment occurrence and its declared species. | PassportApplicationAccessDescription, a U.MethodDescription; portal and service-desk bearers are access-point U.System values under the worked-case premise when that boundary claim obtains. | Dated application-handling and passport-issuance Work occurrences. | Submission, issuance, elapsed-time, and defect observations support claims; evaluation applications bind lead-time or defect results, and separately constituted verdict epistemes state the judgments. |
Key takeaway. The same pattern yields one promise-content episteme in each domain. Direct system-role assignment, PromiseContentUse, evaluation-operation, evidence, acceptance, and publication relations retain their own participants and governors; evaluation remains separately performed U.Work.
Locality replay. In the cloud-storage row, identify CloudStoragePromiseContent-v3, CloudStorageOfferScheme-2026, and EligibleStorageAccounts-EU-2026Q3 as the exact promise-content edition, its effective scheme, and its U.ClaimScope. Then PromiseContentUse(PUT-2026-07-14-1042, CloudStoragePromiseContent-v3, Interval-PUT-1042) ties one dated delivery-work occurrence to that edition. Name a selected model-use structure only in a receiving assertion or use that is actually model-local. If another catalog scheme is consumed, add the exact obtaining F.9 Bridge, the separate claim that it suits this bounded use, and the A.10 evidence-provenance relation with RelianceDisposition=pass. Use B.3 only if an actual named assurance claim about this use is current.
