# Black Mirror S2E4 — White Christmas
**Decoherence bridge:** The Cookie and William's staged [[wiki/Self-Model Ensemble|self-model ensemble]] clarify different forms of reconstruction. A person-shaped model may be operationally useful or experientially significant without settling continuity with its source, and the administrator's control over the environment does not establish identity or legitimate authority.

## Case
A Cookie is a digital copy of a person used as domestic software. It can refuse, experience isolation, learn coercively imposed duties and endure accelerated subjective time. Another Cookie becomes an interrogation target and is later subjected to an immense simulated sentence by an operator.
The episode separates numerical identity from moral fungibility. A copy can be distinct from its biological source and still become non-fungible after acquiring its own experiential history. Computability does not establish property status; administrative access does not confer moral authority; simulation is not unreal to the subject experiencing it.
## Constitutional Questions
- Does copying create a worker, a descendant, a tool or a captive person?
- Who may alter subjective time, and for what purpose?
- Can a confession extracted from a copied subject be legitimate?
## Key Insight
**A copy can be numerically distinct from its source and morally non-fungible once it acquires an experiential history of its own.**
