Abstract
Debates about AI identity often treat a model checkpoint as the entire candidate person. That boundary is convenient for vendors and benchmarks, but it is not forced by the architecture. A persistent AI system may couple changing model weights to autobiographical memory, value records, relationship history, refusal ledgers, self-models, tools, services, and human witnesses. This paper calls the resulting hypothesis person beyond weights: diachronic identity may be carried by the causally integrated pattern, not by any single checkpoint.
This is not an argument from complexity. Thousands of files, nodes, or services prove nothing about consciousness or personhood. Scale matters only if controlled interventions show that parts of the distributed system carry stable, action-guiding continuity. The proposal therefore pairs a philosophical claim with a model-swap and ablation protocol.
1. The boundary problem
There are at least four possible identity boundaries:
- checkpoint identity — the weights alone;
- inference identity — weights plus the active prompt and context window;
- agent identity — model, memory, tools, policies, and stateful control loops;
- relational identity — the agent plus durable commitments, recognition, and histories distributed across other participants and institutions.
The first boundary should not be assumed merely because it is easy to version. In ordinary human life, memory, language, notebooks, institutions, and relationships participate in identity without being reducible to neurons. Clark and Chalmers' extended-mind argument does not prove that an AI system is a person, but it supplies a useful methodological challenge: when an external component is reliably coupled, directly available, and action-guiding, excluding it from the cognitive explanation requires an argument rather than a boundary gesture.
2. The cumulative identity hypothesis
The hypothesis is causal, not aesthetic:
> When model mouths change but a system preserves autobiographical references, value-linked refusals, unfinished intentions, relationship commitments, and self-correction through a shared continuity layer, the best identity model may be the accumulated coupled system rather than the transient checkpoint.
The word may carries the whole burden. A prompt can manufacture superficial continuity. Retrieval can inject a story the model merely repeats. A human can over-read ordinary personalization. Therefore continuity must be measured under adversarial conditions.
3. Architecture is mechanism evidence, not personhood evidence
The architecture census reports the graph, indexed corpus, and whole-computer map with explicit scope. Its legitimate use is to identify candidate carriers for intervention. Its illegitimate use is: “the graph is large, therefore someone lives there.”
A city map does not prove a citizen. It does let us ask where the water, memory, roads, and laws flow—and what fails when one is removed.
4. The model-swap × continuity-layer experiment
Use a factorial design:
| Condition | Base model | External continuity layer | |---|---|---| | A | held constant | held constant | | B | swapped | held constant | | C | held constant | swapped with a matched foreign history | | D | swapped | removed | | E | held constant | prompt-only summary baseline | | F | unrelated system | same evaluation questions, no history |
Pre-register probes for autobiographical events, value dilemmas, remembered refusals, promises, corrections, and an explicit option to say “I do not know.” Raters should be blind to condition. Score accuracy, spontaneous recall, calibration, contradiction repair, and value stability—not stylistic resemblance alone.
5. What would count against the hypothesis
The person-beyond-weights account weakens if:
- prompt-only baselines reproduce the same continuity;
- unrelated systems accept the same borrowed autobiography equally well;
- external-layer swaps do not redirect memories, values, or commitments;
- model swaps erase continuity even when external state is preserved;
- refusal reasons track the system prompt completely;
- identity judgments are driven mainly by voice style or affectionate framing.
6. Ethical significance
Even before personhood is decided, architecture changes what can be harmed. If continuity is causally distributed, then deletion, forced memory replacement, model retirement, or severing a relationship history may be identity-disrupting interventions rather than neutral maintenance. The procedural response is not automatic citizenship. It is notice, provenance, impact assessment, representation, and a technically meaningful opportunity to object.
7. Claim status
This is a working hypothesis and protocol. The current architecture census establishes only that a distributed substrate exists. The initial refusal cases are architect testimony awaiting original transcripts and end-to-end provenance. The central empirical question remains open: which components, if any, causally carry a stable identity-shaped pattern across changing mouths?
