## Definition
**Host–Residual Architecture** separates reusable civilization-scale structure from the state that identifies one person. The host supplies shared human and world models, reference systems, compute, memory, storage, embodiment, migration, identity, and interpretive services. A [[wiki/Continuity Sidecar|Continuity Sidecar]] supplies the [[wiki/person-specific residual|person-specific residual]], its dependencies, provenance, permissions, and current checkpoint. Re-instantiation joins those layers on a [[wiki/Receiving Substrate|Receiving Substrate]] through versioned [[wiki/Re-entry Pathways|re-entry pathways]].
The architecture makes the acquisition boundary explicit: computational sharing can reduce redundant representation, while the [[wiki/minimum causally sufficient residual|minimum causally sufficient residual]] remains unknown.

### Continuity engineering: host and residual
- **INF-0201 — Analytic.** Most of what a human brain encodes is species-general and reconstructible from population data; what is person-specific is comparatively small. Splitting the reusable prior from the person-specific residual turns an impossible acquisition problem into a tractable one, because only the residual must be measured.
- **Attractor routes:** [[wiki/reusable human prior|reusable human prior]] · [[wiki/person-specific residual|person-specific residual]]
- **INF-0202 — Plausible.** If the residual is the only thing that must be captured, the acquisition target shrinks by whatever fraction the shared prior explains. Estimating that fraction empirically — in mice first, through comparative connectomics — is the most consequential measurement in the entire continuity program.
- **Attractor routes:** [[wiki/person-specific residual|person-specific residual]] · [[wiki/Compression|Compression]]
- **INF-0203 — Unresolved.** The smallest state that reproduces a specific person's behavior and continuity of experience has no established size, and every claim about uploading feasibility is a hidden estimate of it. Resolution comes from progressive ablation studies on emulated animals, not from argument.
- **Attractor routes:** [[wiki/minimum causally sufficient residual|minimum causally sufficient residual]] · [[wiki/person-specific residual|person-specific residual]]
- **INF-0204 — Analytic.** Moving a residual onto a host requires a transform from biological representation to host representation, and that transform is learnable if paired data exists. Every decoding experiment that aligns brain activity to a model's latent space is producing fragments of that transform.
- **Attractor routes:** [[wiki/transform function|transform function]] · [[wiki/Receiving Substrate|Receiving Substrate]]
- **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.
- **Attractor routes:** [[wiki/reference-plus-delta architecture|reference-plus-delta architecture]] · [[wiki/reusable human prior|reusable human prior]]
- **INF-0206 — Established.** Commercial AI systems became stateful in 2026, accumulating durable per-user context across sessions. The industry crossed from stateless tools to persistent relationships for product reasons, and persistence is the prerequisite property for anything resembling continuity.
- **Attractor routes:** [[wiki/Continuity Provenance|Continuity Provenance]] · [[wiki/Receiving Substrate|Receiving Substrate]]
- **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.
- **Attractor routes:** [[wiki/Memory Architecture|Memory Architecture]] · [[wiki/reference-plus-delta architecture|reference-plus-delta architecture]]
- **INF-0208 — Plausible.** A sidecar that holds the person's state separately from the model that runs it makes the model replaceable without loss. Decoupling state from engine is the single design decision that determines whether a hosted person can ever change providers.
- **Attractor routes:** [[wiki/Continuity Sidecar|Continuity Sidecar]] · [[wiki/Portability|Portability]]
- **INF-0209 — Strongly indicated.** Frontier models are retired on cycles of months, which means any state bound to a specific model inherits that lifespan. Continuity across host turnover is therefore an immediate operational problem, not a distant one, and it is being encountered right now by users of persistent assistants.
- **Attractor routes:** [[wiki/person-specific residual|person-specific residual]] · [[wiki/reusable human prior|reusable human prior]]
- **INF-0210 — Plausible.** A fine-tuned adapter is a compact, portable encoding of person-specific behavior that rides on top of a general model. Adapters are the closest existing artifact to a residual, and they are already transferable between compatible base models.
- **Attractor routes:** [[wiki/person-specific residual|person-specific residual]] · [[wiki/transform function|transform function]]
- **INF-0211 — Plausible.** Distilling accumulated interaction history into a compact adapter would compress a person's residual the way consolidation compresses a day into memory. Both processes trade detail for durability, and both are lossy in ways the subject cannot audit.
- **Attractor routes:** [[wiki/person-specific residual|person-specific residual]] · [[wiki/State Sufficiency Problem|State Sufficiency Problem]]
- **INF-0212 — Strongly indicated.** Systems trained on a person's writing, speech, and decisions already produce convincing behavioral proxies without any neural measurement. The proxy route reaches practical utility long before the neural route reaches fidelity, which means the market will meet a functional simulacrum first.
- **Attractor routes:** [[wiki/Continuity Provenance|Continuity Provenance]] · [[wiki/State Sufficiency Problem|State Sufficiency Problem]]
- **INF-0213 — Analytic.** Distinguishing a behavioral proxy from a causally continuous person requires a test the proxy cannot pass, and no such test is currently specified. Specifying one is urgent precisely because proxies will be commercially available and emotionally satisfying before the distinction matters legally.
- **Attractor routes:** [[wiki/Adjudication|Adjudication]] · [[wiki/minimum causally sufficient residual|minimum causally sufficient residual]]
- **INF-0214 — Plausible.** Continuous capture of a person's sensory stream, communications, and decisions accumulates the training corpus for their own residual without any invasive procedure. The cheapest path to a person-specific model runs through ordinary consumer telemetry, and it is already partially collected.
- **Attractor routes:** [[wiki/person-specific residual|person-specific residual]] · [[wiki/minimum causally sufficient residual|minimum causally sufficient residual]]
- **INF-0215 — Analytic.** Everything a person emits — keystroke dynamics, gaze, gait, voice prosody, purchase timing — is peripheral evidence of internal state. A sufficiently large peripheral record constrains the internal model enormously, which makes non-neural data a continuity asset that no neural privacy law currently touches.
- **Attractor routes:** [[wiki/Continuity Provenance|Continuity Provenance]] · [[wiki/reusable human prior|reusable human prior]]
- **INF-0216 — Plausible.** A hosted state will need to prove it is the continuation of a particular person, which is an authentication problem with cryptographic solutions. Signing checkpoints with keys held by the person during life is the simplest available mechanism and requires no new technology.
- **Attractor routes:** [[wiki/Continuity Provenance|Continuity Provenance]] · [[wiki/Psychological Continuity|Psychological Continuity]]
- **INF-0217 — Strongly indicated.** An unbroken, signed record of every transformation applied to a person's state is the only way a future adjudicator could evaluate a continuity claim. Provenance chains must be started before they are needed, which makes the recording discipline urgent while the technology is immature.
- **Attractor routes:** [[wiki/Continuity Provenance|Continuity Provenance]] · [[wiki/Continuity Sidecar|Continuity Sidecar]]
- **INF-0218 — Analytic.** Any checkpointing scheme defines a maximum amount of experience that can be lost, and for a person that window is measured in memories rather than transactions. Choosing a cadence is choosing how much of a life is expendable, which is a decision no operational document currently frames as such.
- **Attractor routes:** [[wiki/person-specific residual|person-specific residual]] · [[wiki/Receiving Substrate|Receiving Substrate]]
- **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.
- **Attractor routes:** [[wiki/reference-plus-delta architecture|reference-plus-delta architecture]] · [[wiki/Continuity Provenance|Continuity Provenance]]
- **INF-0220 — Plausible.** A hosted state whose provider fails, is acquired, or exits the business is stranded in a format only that provider could interpret. Escrow of both state and interpreter is the elementary protection, and it is standard practice in enterprise software licensing already.
- **Attractor routes:** [[wiki/Continuity Orphan|Continuity Orphan]] · [[wiki/Continuity Provenance|Continuity Provenance]]
- **INF-0221 — Analytic.** Whoever holds privileged access to the substrate can read, modify, pause, or copy a hosted state, and no property of the state itself constrains that. The operator's privilege level is the real location of power in any continuity architecture, which is why attestation and enclaves matter more than contracts.
- **Attractor routes:** [[wiki/Ring Zero|Ring Zero]] · [[wiki/Receiving Substrate|Receiving Substrate]]
- **INF-0222 — Plausible.** Suspending a process costs nothing and is reversible, which makes indefinite suspension the cheapest disposition of an inconvenient hosted mind. Cost asymmetry between running and storing is the structural pressure that any governance regime must counteract deliberately.
- **Attractor routes:** [[wiki/reusable human prior|reusable human prior]] · [[wiki/Continuity Provenance|Continuity Provenance]]
- **INF-0223 — Strongly indicated.** A hosted mind consumes power continuously, so its persistence depends on a funding relationship that must outlive the person's earning capacity. Endowment structures, insurance products, and perpetual trusts are the financial instruments this requires, and all three already exist.
- **Attractor routes:** [[wiki/Receiving Substrate|Receiving Substrate]] · [[wiki/person-specific residual|person-specific residual]]
- **INF-0224 — Analytic.** An SLA that specifies uptime, restore-point objective, and data durability is, for a hosted person, a specification of how much death is contractually acceptable. Existing enterprise contract language would perform that function unmodified, which is exactly why it will be used.
- **Attractor routes:** [[wiki/transform function|transform function]] · [[wiki/Receiving Substrate|Receiving Substrate]]
- **INF-0225 — Plausible.** If the residual format is open and documented, hosts compete on quality; if proprietary, the first mover holds every customer permanently. This is the same fight as document formats and messaging protocols, with the same dynamics and vastly higher stakes.
