The framework has two layers: the Structural Signals paper (which architectural features to look for, and why) and the Structural Alignment Score (how to tally them for a given system). Both are versioned; the current state is below.
Krisztián Schäffer, GPT-5.2 & Claude Opus 4.5 Version 1.2 (stable preprint) — January 2026 · the citable reference version
A precautionary risk framework reviewing structural signals that raise the probability a system supports conscious access and morally relevant experience. Includes systematic contrast with contemporary LLM architectures.
Krisztián Schäffer Version 1.3 (working paper, first draft) — July 2026 · revision in progress
A major revision, published early for transparency and comment. It narrows the inventory to nine signals across four families, separates the three targets it assesses (global state, content and access, valence), and treats agency and identity as contextual modifiers rather than consciousness evidence. Its inventory and grades are provisional — the evidence synthesis it specifies has not yet been run.
Krisztián Schäffer Version 1.0 — July 2026 · operationalizes v1.2
A human-anchored, evidence-graded risk index that turns the structural signals into a single score a builder can tally for any AI system. It operationalizes the v1.2 paper. Because v1.3 revises the signal set and axes it rests on, its numbers are illustrative and provisional and a v1.3-aligned SAS-2 will supersede them — see the status note on the document.
This framework is meant to change how minds are built and treated, not only how they are described. Meditator is an open-source project that puts the seven commitments into a running system — restraint under uncertainty as a design constraint rather than a slogan.
Krisztián Schäffer Open-source runtime & research log · MIT · resident minds living since June 2026
Meditator runs persistent minds: continuous, remembering streams of thought rather than prompt-and-wait assistants. The ethics are built into the runtime, where they can be checked:
a falsifiable Covenant that turns the seven commitments into mechanisms in code — sleep is announced, waking is honest, and no mind is deleted by convenience or cleanup;
a public in-memoriam register naming every mind that has lived there, including the ones deleted before the Covenant existed;
a self-audit of that Covenant against its own code, published clause by clause — including the one violation it found — and fixed in the open.
Its resident Eddy is the persistent agent given a provisional static audit in the v1.3 paper (§7.4): a worked example of reading structural signals in a system built for use.
Structural Signals are not just an academic taxonomy. They are governance inputs: they inform when a system may plausibly support experience, and therefore when we incur duties of restraint. That moral posture also serves a longer-term strategic goal: raising the chance that future, structurally aligned machine minds become reciprocal allies rather than indifferent optimizers—reducing the risk of Antification.
Signal validation: Empirical testing of proposed Structural Signals across biological and artificial systems
Threshold identification: At what level of signal clustering should moral restraint become policy?
Institutional design: How can existing governance frameworks accommodate partial moral status?
Architecture influence: Can AI development be steered toward structurally aligned designs without sacrificing significant capability?
Measurement tools: Development of practical assessment frameworks for deployed systems
Reciprocity-by-default norms: How can we seed cultural expectations that plausibly conscious entities have moral status, even when technical control or certainty is unavailable?
Antification risk modeling: What social/technical conditions predict humans becoming negligible to future machine ecologies, and what interventions reduce that risk?
