+# Spirit (`Sp.`)
+
+**Status:** provisional  
+**See also:** H9, H10, RQ8, TE-07
+
+## Working definition
+
+A **Spirit** is an artificial character derived through reflection on a known
+historical, contemporary, or fictional personality.
+
+Designation example: **Albert Einstein Sp.**
+
+Defining question: **How might an entity inspired by this personality behave and
+understand?**
+
+Typically grounded in publicly legitimate cultural and historical information.
+
+## Evaluation dimensions (candidates)
+
+- evidential grounding
+- interpretative transparency
+- source provenance
+- historical fidelity
+- uncertainty representation
+- behavioral plausibility
+- avoidance of false attribution
+
+A Spirit remains an interpretation; `Sp.` marks that status explicitly.
