AWS PSM model root

The AWS PSM root is the deployment-oriented container. It owns stages, SAM stacks, AWS policies, documents, and the derived resource index.

`AwsPsmModel`

Represents aws psm model in the PSM vocabulary. It specializes TraceableElement with the details needed for this modeling concern.

Direct supertypes: TraceableElement. Inherited attributes and marker capabilities are documented in the shared kernel; this section lists every attribute declared by this class.

Declared attributes

Attribute	Type and multiplicity	What it captures and why it exists	Accepted values and example
`accountStrategy`	`String` [1]	How AWS account selection is governed across stages. It prevents account identity from being hidden in generated configuration and makes promotion rules reviewable. Transformation role: ETL rule `PIMModel2AwsPsmModel` in `mde/transformations/pim-to-awspsm/root-stage-stack.etl` assigns or materializes this feature while refining `AwsPsmModel`.	A free-form `String`, subject to this class's semantic meaning and any EVL constraints. Example: `Aws Psm Model Account Strategy`.
`regionStrategy`	`String` [1]	The policy for choosing deployment regions, including whether the model is single-region, configurable, or intended for a multi-region posture. Transformation role: ETL rule `PIMModel2AwsPsmModel` in `mde/transformations/pim-to-awspsm/root-stage-stack.etl` assigns or materializes this feature while refining `AwsPsmModel`.	A free-form `String`, subject to this class's semantic meaning and any EVL constraints. Example: `us-east-1`.
`defaultRegion`	`String` [1]	The concrete region used when a more specific stage/resource decision is absent. It is validated because generated templates cannot safely omit their deployment location. Semantic validation: `DefaultRegionRecommended` (default region recommended) in `mde/validation/psm/rules/core.evl` the value must be present and non-blank. Transformation role: ETL rule `PIMModel2AwsPsmModel` in `mde/transformations/pim-to-awspsm/root-stage-stack.etl` assigns or materializes this feature while refining `AwsPsmModel`. Generation role: The artifact generator references this feature in `mde/generation/awspsm-to-artifacts/templates/infrastructure/samconfig.egl`. The artifact generator references this feature in `mde/generation/awspsm-to-artifacts/templates/scripts/deploy.egl`.	A free-form `String`, subject to this class's semantic meaning and any EVL constraints. Example: `us-east-1`.
`namingConvention`	`String` [1]	The human-readable naming policy applied to AWS resources and stacks, preserving operational discoverability across environments. Transformation role: ETL rule `PIMModel2AwsPsmModel` in `mde/transformations/pim-to-awspsm/root-stage-stack.etl` assigns or materializes this feature while refining `AwsPsmModel`.	A free-form `String`, subject to this class's semantic meaning and any EVL constraints. Example: `Aws Psm Model Naming Convention`.
`taggingStrategy`	`String` [1]	The organizational rule for resource tags, including ownership, environment, cost, and propagation expectations. Transformation role: ETL rule `PIMModel2AwsPsmModel` in `mde/transformations/pim-to-awspsm/root-stage-stack.etl` assigns or materializes this feature while refining `AwsPsmModel`.	A free-form `String`, subject to this class's semantic meaning and any EVL constraints. Example: `Aws Psm Model Tagging Strategy`.
`productionMode`	`Boolean` [1]	Whether the model is being prepared for production safeguards. EVL uses it to require production stages and stronger retention, approval, and security posture. Semantic validation: `ProductionModeHasProdStage` (production mode has prod stage) in `mde/validation/psm/rules/core.evl` the flag must be enabled for this rule to pass. Transformation role: ETL rule `PIMModel2AwsPsmModel` in `mde/transformations/pim-to-awspsm/root-stage-stack.etl` assigns or materializes this feature while refining `AwsPsmModel`. Generation role: The artifact generator references this feature in `mde/generation/awspsm-to-artifacts/lib/trace.eol`. The artifact generator references this feature in `mde/generation/awspsm-to-artifacts/lib/validation.eol`.	Either `true` or `false`. Example: `true`.
`partition`	`AwsPartition` [1]	The AWS partition in which resources live, commercial, GovCloud, or China, because ARN and endpoint assumptions are partition-specific. Transformation role: ETL rule `PIMModel2AwsPsmModel` in `mde/transformations/pim-to-awspsm/root-stage-stack.etl` assigns or materializes this feature while refining `AwsPsmModel`.	Exactly one of: `AWS`, `AWS_US_GOV`, `AWS_CN`. Example: `AWS`.
