 # Identity
 
-**Status:** under review  
-**See also:** RQ5, H6, thought experiments TE-02–TE-05, TE-08
+**Status:** revised (Phase I, 2026-08-12)  
+**See also:** RQ5, H6, TE-02–TE-05, TE-08, RN-004, RN-005
 
-## Working definition
+## Disambiguation
 
-**Identity** concerns what makes temporally separated manifestations instances of
-the **same Being**.
+| Question | Soul Frame term |
+|---|---|
+| Same entity over time? | **Identity** (numerical / reidentification) |
+| What continues? | **Continuity** (may branch) |
+| Historical relatedness after branch? | **Lineage** |
+| What is it like? | **Characterization** (narrative/character) |
 
-Working hypothesis: identity is **substrate-independent but continuity-dependent**.
-Replacing the technical Actor need not replace the Being if sufficient continuity
-is preserved.
+Identity ≠ Continuity ≠ Lineage ≠ Character.
 
-## Continuity candidates
+## Core formulation
 
-- informational continuity
-- psychological / memory continuity
-- narrative identity
-- relational continuity (recognition and relationships)
-- bodily / embodiment continuity (where applicable)
+> A Being continues not because its state remains the same, but because its
+> changes remain part of one appropriately connected history of self-individuation.
+>
+> When that history branches, identity becomes lineage.
 
-## Hard cases
+## Continuity profile (constitutive dimensions)
 
-Forks, merges, backups, multi-manifestation, amnesia, gradual component replacement.
+Causal, organizational, psychological, autobiographical/narrative, normative,
+relational.
+
+**Anchors / evidence (not constitutive alone):** provenance, address, substrate.
+
+## Topology labels
+
+`CONTINUOUS | DEGRADED | UNCERTAIN | SUCCESSOR | FORKED | RECONSTRUCTED | USURPED | TERMINATED`
+
+## Implications for artificial systems
+
+- Actor/Body replacement can preserve identity (substrate independence + continuity dependence).
+- Sameness of data is not sameness of Being.
+- Forks require governance; perfect copy while original continues yields FORKED lineage.
+- Ghosts default to authorized succession/representation, not automatic numerical identity.
+- Explicit identity governance is required because state is inspectable, copyable, editable.
