A.6.S:5 - Worked cases
Ordinary cheap stop. An editor adds the law Refund does not increase net balance to PaymentBoundarySignature and issues edition 4. The changed ClaimGraph identifies a new signature episteme; the edition or continuity relation and the editor’s Work are stated only when the receiving claim uses them. If nobody needs reusable constructor vocabulary, stop. No ConstructorSignature or pair object is created.
A.6.S:5.1 - Repeated engineering of a service boundary
Working situation. Several client teams and two authoring Systems will revise and republish the same payments boundary over multiple editions. They need one reusable account of the allowed authoring operations.
TargetSignature: PaymentBoundarySignature declares operations such as Authorize, Charge, and Refund; the participant meanings and ref modes reused in any actual relation declaration; laws such as idempotent charging; and the external-API applicability boundary. Keep operation arguments and results under A.6.1; A.6.5 governs participant positions only in an exact RelationSignature.
ConstructorSignature: PaymentSignatureEngineering is justified because the named authoring and review uses reuse the same operation vocabulary and laws. It may declare:
- a by-value law revision and a reference-retargeting operation when those distinctions are reused; apply A.6.5 only if the move concerns a SlotSpec in an exact RelationSignature, keeping ordinary law-content revision under its declaration rule and operation arguments/results under A.6.1;
- a direct calibration, provenance, or other relation assertion under its own pattern, with an A.6.6 declaration-change label only when a receiver tracks its represented history; and
- an E.17 publication operation for the repeated Plain, Tech, and interoperability publications, with a reusable view-producing operation only when needed and any A.6.3 construction identified separately.
PaymentSignatureEngineeringPipeline, if admitted as a System, may apply the described operations. Any claimed dated authoring or publication Work requires its complete A.13 performer core and independent A.15.1 admission as in §4.0. The ConstructorSignature does not act. Add the separate F.6 Work-assignment relation only for precise attribution through that same obtaining assignment; state an application binding, carrier, evidence relation, or additional classification or assignment only when its own claim is current.
The sentence Charges are recorded in Ledger L for the external API must first name and test its actual direct relation. Do not replace it with declareBase, a generic baseRelation, or a witness package. If later comparison needs a stable representation of that assertion and its scope, A.6.6 may add the optional declaration history.
The publication faces are faithful forms over the exact TargetSignature edition for their bounded readers and uses. Any claim that the selected episteme is a U.View requires its own E.17.0 conformance under §4.4. Guarantees idempotency is unpacked into the actual law, any separate mechanism admission condition, deontic commitment, and evidence-use claim; the word contract creates none of them.
A.6.S:5.2 - Repeated engineering of a model-correspondence signature
Working situation. A research group maintains a correspondence signature across several model editions and publishes mathematical and engineering views. A second group must reproduce the same revisions.
ModelCorrespondenceSignature is the TargetSignature. Its vocabulary, laws, and applicability state the exact correspondence claim and the schemes in which it is interpreted. An actual F.9 Bridge is cited only when a relation between two exact F.17 cells obtains and a separate bounded-use claim is current.
CorrespondenceSignatureEngineering is an optional ConstructorSignature because the second group reuses its declared revision and view-production vocabulary. A reference-retargeting operation may identify a new model edition. An A.6.2 arrow may compare exact source and receiving signature epistemes and any named neighboring facts; it changes none of those facts. The actual application, authoring System, Work, resulting episteme, and publications remain separate.
If the project only changes one reference dataset window once, state that direct revision and any needed Work or successor edition, then stop. Do not create the ConstructorSignature merely to host retime.
