The row is addressed by its engine-derived group id so compact code-path artifacts can be joined without a coordinate guess. ## OpenAPI ````yaml /api-reference/bundled.yaml get /v0/experimental/component/{id}/discriminator_code_paths openapi: 3.1.0 info: title: Gable API description: > API to interact with the Gable platform ## Authorization All API requests require an API key to be passed in the `X-API-KEY` header.

Emitted by sca-prime for every strand step regardless of kind; absent on legacy DDB-sourced anchors that predate the strand read path. transform: type: string description: > sca-prime's transform mechanism for the call at this step — what the call does to the value rather than where it flows. Current vocabulary: `reformat`, `calculation`, `aggregation`, `encryption`, `decryption`, `hashing`, `redaction`. Intentionally an open string rather than an enum: sca-prime documents the vocabulary as growable and requires consumers to tolerate values they do not recognize, so an enum here would reject otherwise-valid scans the day Prime adds a mechanism. Absent when the step's call carries no transform tag, and on legacy DDB-sourced anchors. containingFunction: type: string description: > Fully-qualified name of the function whose body contains this step — the enclosing function, not the callee named in `description`. sca-prime emits it as a METHOD node id on the strand-sourced code-paths file; the read resolves that id against the run's strand metadata index. Best-effort: absent for steps in external, unparsed, or synthetic functions, when the metadata index is unavailable, and on legacy DDB-sourced anchors. required: - anchorId - name - codeUri CodeURI: type: object description: >- Code URI is a unique identifier for a code location.
