====== TWIN-002b — Support Multiple Twin Realizations ======

[[dido:03-dido-te:99-annexes:annex-c-requirements:03-functional-requirements:03-03-twin-node-requirements:twin-002-associate-twin-realizations:start|Go to TWIN-002 — Associate Twin Realizations]]

===== Statement =====

The [[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]] SHALL support association of more than one [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_realization|Twin Realization]] with the same [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_identity|Twin Identity]].

===== Source =====

  * [[dido:03-dido-te:99-annexes:annex-b-references:dte-001|[DTE1] U.S. Patent Application US20220237111A1]], virtual and physical Twin Node concepts and identifiers shared among Twin Nodes
  * [[dido:03-dido-te:99-annexes:annex-b-references:dte-002|[DTE2] Non-Traditional BAA Submission]], F17, //Twin Nodes Selection//

===== Rationale =====

The source material distinguishes multiple realizations of the same logical twin, including virtual and physical or real-world Twin Nodes.

Allowing more than one [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_realization|Twin Realization]] to reference the same [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_identity|Twin Identity]] allows the DIDO-TE to select among alternative realizations without changing the logical twin represented by a test.

This multiplicity also supports comparison of behavior or results produced by different Twin Realizations associated with the same Twin Identity.

===== Applies To =====

  * [[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_identity|Twin Identity]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_identifier|Twin Identifier]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_realization|Twin Realization]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_realization_identifier|Twin Realization Identifier]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_realization_type|Twin Realization Type]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_node|Twin Node]]

===== Verification =====

Verification confirms that:

  - A Twin Identity can be associated with at least two distinct Twin Realizations.
  - Each associated Twin Realization retains its own Twin Realization Identifier.
  - Each associated Twin Realization references the same Twin Identifier.
  - Twin Realizations associated with the same Twin Identity may have different Twin Realization Types.
  - Adding another Twin Realization does not change the Twin Identity or the identifiers of existing Twin Realizations.

Verification includes a Twin Identity associated with at least one virtual Twin Realization and one physical or real-world Twin Realization.

===== Traceability =====

{{backlinks>.}}

===== ConOps Relationship =====

This requirement supports registration and management of alternative Twin Realizations that represent the same logical twin and supports later selection or comparison of those realizations during Test Execution.
