reference-plus-delta architecture

# reference-plus-delta architecture **Entity class:** Technology, method, or technical system **Collections:** [[collections/Neurotech|Neurotech]] · [[collections/Consciousness Continuity|Consciousness Continuity]] ## Definition **Reference-Plus-Delta Architecture** stores shared structure once and represents each instance by reference identity plus the differences needed to reconstruct that instance. Production precedents include CRAM reference-based genomic compression, parameter-efficient model adaptation, OpenUSD scene instancing, container layers, and shared neural cores with individual readouts. In continuity architecture, the same representation principle separates a [[wiki/reusable human prior|Reusable Human Prior]] from a [[wiki/person-specific residual|Person-Specific Residual]]. The attainable compression ratio for a person is an open empirical quantity. ## Relationships  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]] and [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]].

Ten million people do not need ten million cities** provides the narrative context for **reference-plus-delta architecture**: This is not a thought experiment. - In [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]], **II. The host is reusable; the person is the delta** provides the narrative context for **reference-plus-delta architecture**: Epigenetics requires a qualification, and the qualification improves the model rather than weakening it.  ## Research Edges  #### Consciousness mapping and transfer graph patch — 2026-09-10 **Collections:** [[collections/Neurotech|Neurotech]] · [[collections/Consciousness Continuity|Consciousness Continuity]] **Relationship source:** [[research/Consciousness Mapping and Transfer Ecosystem Relationship Graph - 2026-09-10|Consciousness Mapping and Transfer Ecosystem Relationship Graph — 2026-09-10]] **Related source articles:** [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] · [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]] · [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]] · [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]] #### Outgoing typed edges - **Edge 644 — `has_analogue` → [[wiki/CRAM reference-based genomic compression|CRAM reference-based genomic compression]]** — **ARTICLE_ANALYTIC**; evidence `ARTICLE_NEW`.

Shared immutable base plus compact specialization.  ## Research Inferences  These entries translate the forward-looking register in [[research/Research Inferences|Research Inferences]] into ordinary wiki prose. The tier labels apply to the inference, not automatically to every factual anchor inside it. The interpretive frame comes from [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] and [[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]]. Collection route: [[collections/Neurotech|Neurotech]]. - **INF-0205 — Strongly indicated.** Storing a shared base plus a per-person delta is how every large software distribution system already works, and it is orders of magnitude cheaper than storing complete copies. Continuity infrastructure will converge on this pattern because the economics leave no alternative.  ## Research Inference Attractors  These are secondary semantic placements for the inference attractor network. Each statement keeps its original ID and tier; its canonical cluster page links back to every destination. Source register: [[research/Research Inferences|Research Inferences]]. Interpretive context: [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] and [[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]]. Collection route: [[collections/Neurotech|Neurotech]]. - **INF-0207 — Analytic.** Retrieval-augmented systems separate a small working context from a large external store, which is structurally the hippocampal-neocortical division of labor. Systems converge on this architecture independently because the constraint — bounded fast memory, unbounded slow memory — is the same in both substrates. - **Canonical cluster:** [[wiki/Host–Residual Architecture|host-residual architecture]] - **INF-0219 — Unresolved.** Two instances started from one checkpoint diverge immediately and irreversibly, and no framework specifies which holds the original's obligations or entitlements. The question becomes practical the first time a backup is restored while the original is still running. - **Canonical cluster:** [[wiki/Host–Residual Architecture|host-residual architecture]]
