InstructionComposition
Type CDM 7.2.0Represents an Instruction Composition orchestration, holding data, shared history, and an ordered sequence of CompositionSteps. Each InstructionComposition will have one or more CompositionStps.

Attributes
All 6 declared on InstructionComposition. Cardinality in amber is required.
| Name | Type | Card. | Description |
|---|---|---|---|
| compositionStep | CompositionStep | 1..* | Ordered sequence of CompositionSteps that drive the Instruction Composition process (atomic actions, calculations, validations). |
| compositionState | CompositionState | 0..1 | Shared state accumulated across executed steps, capturing intermediate and final outputs of the Instruction Composition process. |
| instructionCompositionType | InstructionCompositionTypeEnum | 1..1 | Type of Instruction Composition being orchestrated (e.g. ResetInstruction). |
| identifier | string | 1..1 | Unique identifier of this InstructionComposition instance. |
| tradeId | TradeIdentifier | 0..1 | Identifier of the underlying trade to which this InstructionComposition relates. |
| instructionCompositionOutput | InstructionCompositionOutput | 0..1 | Outputs of each Instruction Composition process. The recording of this information will be done in a single step at the end of the process for each Instruction Composition. |
Conditions
Validation rules the model enforces on this type, in Rune. An instance that breaks one of these is invalid CDM, whatever produced it.
InstructionCompositionType Condition
All CompositionSteps within this InstructionComposition must declare the same InstructionCompositionType as the InstructionComposition itself.
compositionStep -> compositionStepInstruction -> instructionCompositionType all = instructionCompositionType CompositionStateByType Condition
Validates structural integrity by ensuring that the specific InstructionCompositionState type provided (e.g., ResetInstructionState) is strictly aligned with the declared InstructionCompositionType.
if instructionCompositionType = ResetInstruction
then (compositionState switch
ResetInstructionState then True) = TrueFunctions
Model functions that produce or consume this type. These are the CDM's own behaviour — the logic a correct implementation has to match.
| Function | Role | Description |
|---|---|---|
| Create_InstructionComposition | returns | Creates a new InstructionComposition instance by appending a CompositionStep derived from the provided instruction, updating any previous compositionState, and producing the Instruction Composition Output if at the end of the Instruction Composition process. |
| Create_InstructionComposition | takes | Creates a new InstructionComposition instance by appending a CompositionStep derived from the provided instruction, updating any previous compositionState, and producing the Instruction Composition Output if at the end of the Instruction Composition process. |
| NextCompositionStepToExecute | takes | Determines the next logical execution step for a given Instruction Composition by evaluating its current execution history and process type. |
