1. Function
The Stance Selection (PGM‑STS) AIM is a Sub-AIM of Personality Alignment (PGM‑PAL). It selects the personality stance appropriate to the User State and the context.
PGM‑STS:
- Receives the User State, the Resolved Context and the AUC-PAL Request.
- Selects the personality stance appropriate to the User State and the resolved context, applying role and locale constraints. The stance is not necessarily a mirror of the User State.
- Produces the Selected Stance.
PGM‑STS does not compose the A‑User State.

8. Conformance Testing
Table 2 provides the Conformance Testing Method for the Stance Selection (PGM‑STS) AIM.
If a schema contains references to other schemas, conformance of data for the primary schema implies that any data referencing a secondary schema shall also validate against the relevant schema, if present, and conform with the Qualifier, if present.
| Receives | User State | Shall validate against the User State schema. |
| Resolved Context | Shall validate against the Resolved Context schema. | |
| AUC-PAL Request | Shall validate against the AUC-PAL Request schema. | |
| Produces | Selected Stance | Shall validate against the Selected Stance schema. |
