This entry is routed through [[collections/Consciousness Continuity|Consciousness Continuity]], [[collections/Neurotech|Neurotech]], and [[collections/Machine Succession|Machine Succession]]. Its source context is developed in [[articles/Mind Uploading and AI — The Host is Reusable and the Person is the Delta|Mind Uploading and AI — The Host is Reusable and the Person is the Delta]], [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]], [[articles/The Last Migration Will Not Be Human|The Last Migration Will Not Be Human]], and [[articles/The Magic Kingdom and the Managed State|The Magic Kingdom and the Managed State]]. Status-qualified source edges are preserved in the terminal Research Edges section.
### Key Relationships
- **Microsoft model system** separates harness from model family. Microsoft says the model is substitutable.
- **Microsoft model system** separates context from model family. Context remains external.
- **Microsoft model system** separates memory from model family. Memory remains external.
- **Microsoft model system** separates action space from model family. Action space remains external.
- **Microsoft model system** is associated with model substitutability. Microsoft explicitly cites business continuity and resilience.
### Technology and research relationships
- The technical comparison identifies a convergence: **Microsoft model system** converges technically with [[wiki/Host–Residual Architecture|Host–Residual Architecture]]. Very close software architecture analogue: durable harness/context/memory survives model substitution.
### Additional Documented Relationships
- **Microsoft Model System** is connected in the corpus with [[wiki/Personal Authoritative State|Personal Authoritative State]]. Durable state can remain external while underlying model is swapped.
- **Microsoft Model System** is connected in the corpus with [[wiki/Substrate Independence|Substrate Independence]]. Model family becomes replaceable while higher-level state/harness persists.
- **Microsoft Model System** is associated with [[wiki/Ports and Adapters|Ports and Adapters]]. Microsoft explicitly cites business continuity and resilience.
