Held-out rules
Can the model predict unseen ECA rules?
Feature-backed rule descriptions transfer; ID embeddings do not.
The Experiments surface where validation runs and assay plans are scheduled, tracked, and tied back to claims.
The experimental track holds ideas outside the primary product path until they survive concrete artifacts: run configs, generated mechanisms, verifier receipts, tests, and explicit claim boundaries. RuliadBench tests observer-relative computation; the epigenome track tests whether chromatin-fidelity peptide hypotheses can be configured without pretending they are validated biology.
The tensor is Y[rule, init, time, observer, observable]. The model learns embeddings over computations and predicts coarse readouts. This keeps the target aligned with computational irreducibility: exact microscopic evolution may require running the computation, while observer-level summaries can still be compressible.

Wolfram Science connection. The ruliad frames physics and computation as an enormous space of possible rules and histories. RuliadBench is a small, executable slice of that idea: sample a known computational universe, choose observers, and measure which observer-relative facts can be learned without pretending to shortcut all microscopic computation.
Can the model predict unseen ECA rules?
Feature-backed rule descriptions transfer; ID embeddings do not.
Can it generalize to unseen starting states?
Initial-state summaries carry real predictive structure.
Can it forecast beyond trained time steps?
Coarse behavior extrapolates better than ID lookup, but this remains the hard split.
Can it infer a new measurement operator?
Observer metadata helps, but real observer transfer needs richer operator semantics.
A learned ID embedding gets very low random-row error, but that is mostly memorized geometry. The feature-backed residual model is the meaningful result because it has rule bits, initial-state summaries, time features, and observer metadata for truly excluded axes.
Exact microstate prediction at held-out horizons still has roughly 22-32% bit error in this run, while coarse observers remain substantially more predictable. That is the scientific point: the model is not replacing computation, it is learning what an observer can compress.
Replace rule, initial condition, time, and observer with cell context, perturbation, dose/time, and readout. The same tensorized intervention question becomes whether unseen biological state transitions have learnable, observer-relative structure.
Current run: build/ruliadbench/eca_256_feature_strict/model/strict/SUMMARY.md. The section reports experiment evidence, not product claims or wet-lab evidence.
The latest configuration turns the Information Theory of Aging discussion into a bounded DiscoveryLab experiment. It focuses on peptides for chromatin-interface reader/writer/eraser targets, DNA-repair-coupling, and epigenome-output assays, with forbidden states treated as first-class verification targets.

SINCLAIR.md frames the information-theory-of-aging thread as a useful hypothesis, not a product claim. The configured objective is epigenomic fidelity: restore cell identity and chromatin order while penalizing dedifferentiation, DNA damage, oncogenic proliferation, and broad chromatin disruption.
The Swift plan includes parent, negative, and near-miss calibration controls alongside discovery candidates, so the batch cannot collapse into top-hit-only reporting. The local in-silico submission completes across the assay panel and records the denominator policy.
The SIRT6 / heterochromatin TensorLang slice deliberately exposes risky repair-chromatin couplings. The manifest is not fully green; failed efficacy and safety obligations are the point because they identify where the encoded mechanism overreaches.
Wolfram Science connection. The same observer-relative discipline from RuliadBench applies here: the system does not claim to solve the full biological evolution. It chooses a finite mechanism slice, names the observer readouts, and lets TensorLang plus PathwayLean show exactly which claims pass, fail, or require wet-lab evidence.
